When Dutch prog rock legends Kayak released album number Seventeen
longstanding keyboard player Ton Scherpenzeel looked back and pondered what might have been
Dutch proggers Kayak came close to breaking America in the 70s
Kayak’s last remaining original member Ton Scherpenzeel looked back over their career and discussed what went wrong
his hopes for the future and his fear of flying…
Nor should there be any, of course. Kayak’s history dates back to 1972
when the teenaged Scherpenzeel and drummer Pim Koopman became friends at a volleyball club in Hilversum
The pair knew their eventual lead vocalist Max Werner as a fellow student at a local music conservatory
completing the team with guitarist Johan Slager and bassist Cees van Leeuwen
The band achieved huge success right off the bat with the following year’s debut album See See The Sun and its hits
it was as good a start as anyone could have wished for.”
Max Werner decided to abandon the mic and become a drummer
The timing of such a switch could not have been any worse
reach Number 55 on America’s Billboard chart and threaten to climb higher still
Forced to seek a replacement singer and unable to tour there thanks to Scherpenzeel’s fear of flying
Kayak’s American dream was abandoned to wither and die
“Max hated his own voice – he had never wanted to be the lead singer when we started,” Scherpenzeel states
‘If you want me to remain in the band
I will drum.’ He wasn’t the best drummer in the world
we’d still have his voice along the drums
America felt a lot further away than it does now
Everything was done by letters and phone calls but without having to change things around something very big could have happened for Kayak there.”
disappointment can still be heard in Scherpenzeel’s voice
To have come within touching distance must have been especially heartbreaking
the full significance didn’t really dawn on me,” he admits
“We had a number one album in Holland and we were busy
but it’s only afterwards when you see the paperwork and statistics
when they’re out there on the internet
Kayak could really have been something.’”
Scherpenzeel used Kayak’s absence to join Camel from 1984 onwards
Scherpenzeel was thrilled to hook up with Andy Latimer and company
alternating between full-time band membership and touring muso status and appearing on Stationary Traveller
It was the keyboardist’s problems with aviation that made it difficult for this relationship to continue
Despite having sought various potential remedies
things haven’t really changed for him
“If it is not really necessary for me to fly
Kayak were invited to appear on a popular Dutch TV show
Things went so well that Scherpenzeel had no qualms with a permanent reunion
though this wasn’t as simple as it sounds
“I had remained in contact with Pim Koopman
the other important member of the band who
and we took things slowly at the start,” he relates
Scherpenzeel and Koopman first discussed working together again in 1995
but it would take a further four years for Kayak to be reborn
“We had a manager who forbade us to use the name,” Scherpenzeel explains
It took his death in ’98 for us to receive the all-clear.”
Regrettably, Koopman also died unexpectedly in 2009. In 2014, several line-ups later, a further obstacle arose when Kayak lost co-lead singers Edward Reekers and Cindy Oudshoorn before a tour for the rock opera Cleopatra – The Crown Of Isis
a project that the group had spent two years preparing for
Kayak’s current biography pointedly describes those exits as “unexpected and inconvenient”
“I cannot say it any better than that,” comments Scherpenzeel through gritted teeth. Kayak replaced a man and woman with a solitary male – Bart Schwertmann – and their latest, all-new line-up also includes Kristoffer Gildenlöw, formerly of Pain Of Salvation
though Scherpenzeel played most of the album’s bass parts himself
So belated was Kayak’s tie-in with InsideOut that
Scherpenzeel is thrilled by the possibilities of association with one of the biggest and most forward-thinking labels of the genre
“This is the first time in 12 or 13 years that we’ve had a record label,” he chuckles
but the experience taught us that to take things further you really do need extra support.”
Kayak’s music is certainly blessed with commercial potential
though at 11 and 10 mins respectively the grander pieces La Peregrina and Walk Through Fire really allow them to stretch out
music must sound organic – it’s not a matter of how clever it is,” Scherpenzeel stresses
“I love shorter songs just as much as the epic ones
but the format of verse-chorus-verse-chorus is just as fulfilling
Pop music has been a part of our repertoire: we are a two-sided band and that has sometimes confused our audience
but it’s something that I cannot change.”
Andy Latimer is a guest on Ripples On The Water
a beautiful instrumental piece that Scherpenzeel wrote intentionally for the guitarist
he plays one note and you know it’s him,” Scherpenzeel smiles
“I’ve always loved Camel’s music
Maybe I’ll go back to Camel someday: it’s up to Andy.”
Kayak look set to be busy over the next couple of years
they last performed in the UK back in March 1977 on a bill with Jan Akkerman and singer Kaz Lux who were promoting their concept album Eli
“Jan didn’t want to play any Focus material which left the audiences disappointed
so it was cut short,” Scherpenzeel recalls
this was the band’s one and only foray to Britain to date
of course Scherpenzeel is anxious to return under more favourable circumstances
with just the English Channel between our two nations
“European gigs are always possible – I did some two years ago with Camel
Of course Kayak want to play wherever possible

Interview by Paul González-Morgan of Marine Strategy – Ben van Scherpenzeel
Policy & Plans at the Port of Rotterdam
is passionate about continuous improvement with a focus on ports and shipping in every aspect: nautical
Ben’s past experience onboard vessels of Shell and Holland America Line
together with the knowledge he has gained of the port since 2004
have been applied to initiate and develop many different projects that have had a positive impact on the port’s ecosystem and further afield across the shipping industry
Container throughput at the Port of Rotterdam has risen significantly in Q1 2018 to 3.5 million TEU per quarter
The continued growth in container throughput is a confirmation that Rotterdam is taking an increasingly important position in the maritime connection networks of large shipping company alliances
We are seeing a somewhat more measured growth after the significant growth last year
and this is entirely in accordance with our expectations
What are the challenges of Marine Spatial Planning in the context of the Port of Rotterdam
For traffic approaching the Port of Rotterdam
we’ve worked hard together with our national authorities and all stakeholders at sea to create sufficient space for safe navigation and wind farms
we’ve concentrated on deepening the river towards the Botlek area
Overall it’s a challenge to use the existing infrastructure as efficient as possible by better planning – not only of ships but also related to maintenance like dredging
Port call inefficiencies result in unnecessary delays costing billions in lost revenue and CO2 emissions
How has the Port of Rotterdam optimised vessel calls to maximise efficiency
This will be achieved by working on maximum cargo on board by online depth information
This will mean taking into account “Just In Time” arrivals by exchange of ship planning – platform to exchange has become life: Pronto
Fundamental for both data exchanges is to have standards that work for shipping port to port worldwide
so parties do not build in unnecessary safety margins as they fully understand and trust the information provided
Please talk to us about the importance of information exchange between all parties in the logistics chain:
The departure time is the cornerstone to port logistics
Most departure time dictate the arrival time of another vessel
and that arrival time is key for planning resources for nautical services (pilots
cargo services and vessel services (bunkers
departure time depends on many parties: most of all terminal operations
but certainly also bunker operations or any other critical service a vessel needs to complete before departure
What are the three key elements that define productivity at a port terminal
and avoiding idle time when commercial operations have finished
Severe weather conditions can impact port operations
How do you minimise the down-time at the terminal
allowing ships to remain alongside safely under adverse weather conditions
Is Blockchain a solution to increase port efficiency
Last year the Municipality of Rotterdam and the Port of Rotterdam Authority jointly started BlockLab: a field lab for Blockchain
Blockchain technology offers considerable potential to change the way we manage supply chains
Its main contributions will be increased compliance and transparency
and find more effective ways of resolving trust issues
High-impact is therefore to be expected within the domains of supply chain finance and cross chain collaborations – especially when chains are decentralised and involve numerous stakeholders and transactions
BlockLab puts Blockchain technology into practice
The Lab develops the use of cases with alliances of engineers
Is the port fully aligned with the demands of the ocean supply chain
We’re working together with GS1 to connect to the supply chain standards
allowing better resource planning in warehouses and factories
How is the increasing size of ships shaping your plans for the port
Ten years ago we already designed the Maasvlakte for the ships we have today
We already applied more and stronger bollards
based on the new IACS guidelines which will enter into force this year
how do you see Brexit affecting the Port of Rotterdam in terms of capacity
We all agree that Brexit will have its challenges however
the Port of Rotterdam is treating this matter as a top priority and is fully committed in talking to all stakeholders (Dutch Government
etc.) with a focus on contingency plans to ensure that the transition will go as efficient as possible
What future plans do you have for the port
The Dutch port infrastructure has been elected best port infrastructure in the world by the World Economic Forum for the sixth consecutive time
A good infrastructure is essential for a port’s growth and development
Billions have been and will be invested in the expansion of the intermodal network
state-of-the-art terminals and ICT systems and the Offshore Center Rotterdam to name a few
the digital infrastructure is of major importance
By creating transparency across the chain and by sharing data
we can further increase the efficiency and reliability of the logistics chain
The Port of Rotterdam Authority invests 150 to 200 million euros per year in its port infrastructure
Important investments for the coming year include the development of the Hartel Tank Terminal and the changes to the port railway via Thamesweg
eliminating the clash between transport by rail and ocean-going vessels

Kayak’s 18th studio album ‘Out Of This World’ will be out on May 7th
Legendary Dutch progressive rockers Kayak recently announced they will return with their 18th studio album ‘Out Of This World’ on May 7th
Following the launch of the album’s first single in February
they are now pleased to reveal the follow-up
Ton Scherpenzeel comments: “Not the kind of song you’d expect from Kayak
We get a little but disturbing peek inside the mind of someone who is overly obsessed by what he thinks is his love for another person.”
The album is now also available for pre-order, arriving as a Limited CD Digipak, Gatefold 2LP + CD, and as Digital Album. An exclusive blood red vinyl edition is available directly from the band. Pre-order now here: https://kayak.lnk.to/OutOfThisWorld
The full track-listing is as follows:
spanning 70 minutes of energetic and incredibly diverse material- though still very much recognizable as Kayak
It is clear that the new found energy has gained even more momentum since Hans Eijkenaar rejoined the group
Although they were forced to cancel all tours because Ton Scherpenzeel suffered a heart attack at the end of 2019
and immediately after that because of the Covid pandemic
The current line-up of the band is as follows:

Interface announced this week it has reached a series of major sustainability milestones at its European manufacturing facility in Scherpenzeel, The Netherlands. As of January 2014 the plant has been operating with 100 percent renewable energy
“2014 is a landmark year for us in many ways as we celebrate 20 years of Mission Zero
and these figures from our European manufacturing operations show just how far we’ve come and what can be achieved with the right mind set and ambition," said Rob Boogaard
while our achievements are to be celebrated
this is certainly not a time to be complacent
Mission Zero is not simply about reducing our own direct impacts — it’s also about taking full responsibility for the entire lifecycle of our products
Our goal is to cut the umbilical cord to oil
with the result that 44 percent of our raw materials in Europe are already recycled or bio-based
We’ve come a long way but our Mission continues.”

The V-ATPase is the main regulator of intra-organellar acidification
Assembly of this complex has extensively been studied in yeast
We identified 11 male patients with hemizygous missense mutations in ATP6AP1
encoding accessory protein Ac45 of the V-ATPase
Homology detection at the level of sequence profiles indicated Ac45 as the long-sought human homologue of yeast V-ATPase assembly factor Voa1
restored V-ATPase-dependent growth in Voa1 mutant yeast
Patients display an immunodeficiency phenotype associated with hypogammaglobulinemia
hepatopathy and a spectrum of neurocognitive abnormalities
Ac45 in human brain is present as the common
Our work unmasks Ac45 as the functional ortholog of yeast V-ATPase assembly factor Voa1 and reveals a novel link of tissue-specific V-ATPase assembly with immunoglobulin production and cognitive function
we describe a novel ATP6AP1-linked immunodeficiency and identified disease mutations in ATP6AP1 in 11 male patients with abnormal protein glycosylation
Yeast V-ATPase assembly factor Voa1 was predicted to be homologous to Ac45
which was confirmed by functional complementation of Voa1 mutant yeast with the processed C-terminal domain of Ac45
Identification of different Ac45 protein isoforms in human brain
liver and B cells indicated the presence of tissue-specific regulation of organelle acidification
The dominating clinical symptoms displayed by the present cohort of patients with various ATP6AP1 mutations (Table 1) include hepatopathy and immune abnormalities
Recurrent bacterial infections were associated with hypogammaglobulinemia
ranging from plantar abscesses and gastrointestinal infections in family 1 to multiple episodes of childhood pneumonia and purulent otitis media in families 2–6
Several patients were successfully treated with intravenous immunoglobulins
some of the patients responded very poorly to childhood vaccinations
Hepatopathy ranged from mild hypertransaminasemia to cirrhosis and end-stage liver failure
gastric problems were noted in the majority of patients and laboratory abnormalities included leukopenia
The two brothers from family 4 displayed high-normal levels of IgD+/CD27− naïve B cells and lowered levels of IgD+/CD27+ intermediate and switched memory B cells
suggesting a problem in B-cell differentiation
Patients with the p.E346K substitution (families 3–5) showed in addition splenomegaly
abnormal hepatic histology and neurological symptoms such as epilepsy
mild intellectual disability and behaviour abnormalities
Muscle weakness with mildly elevated serum creatine kinase (CK) was demonstrated in a few patients
the presence of the p.E346K mutation predicted a more severe phenotype within the ATP6AP1 disease spectrum
which is in accordance with the early death of two patients (3.2 and 5.1) due to liver failure
2 and 6 display a milder disease course and are currently doing well without cognitive impairment
radiography showed no signs of osteopetrosis as observed in ATP6V0A3 deficiency
There was no apparent renal phenotype with no signs of metabolic acidosis
Hypokalemia was reported for patients 3.1 and 5.1
no signs for renal tubulopathy as observed in ATP6V0A4 deficiency were seen

cleaved-Ac45-KKNN function is comparable to that of Voa1
While Ac45 protein levels were lower than Voa1
levels for mutated Ac45 proteins were unchanged compared with non-mutated Ac45 protein
reduced V-ATPase function observed for the Y313C or E346K mutation cannot be ascribed to decreased protein abundance
Though GFP-tagging slightly reduced fitness of processed Ac45-KKNN on restrictive medium (data not shown)
dilysine-dependent ER localization was verified
these results indicate that the human and yeast proteins function about equally well in V0 V-ATPase assembly in the ER
likely at least some of the symptoms are related to V-ATPase dysfunction
which is supported by our studies on V-ATPase restricting growth conditions in yeast
The question is why these systems are affected
Possible explanations could include the tissue-specific processing of Ac45 or the existence of additional functions of Ac45 beyond pH regulation via its effect on the V-ATPase
Our studies in human hepatocytes show that Ac45
in contrast to what was observed in neuroendocrine cells
mostly localizes to the early secretory pathway
This is in agreement with the presence of mostly intact-Ac45 carrying non-processed high-mannose glycans
Further studies are needed to elucidate the mechanisms driving differential Ac45 glycosylation and processing in brain
since tissue-specific forms of Ac45 could suggest a possible mechanism for the tissue-restricted disease symptoms in Ac45-deficient patients
A glycosylation defect therefore may affect B-cell activation and thus antibody production
or pH regulation are mainly affecting antibody production by a defective accessory subunit of the V-ATPase
combined with its observed steady-state localization in the early secretory pathway (ER
suggests that differential proteolytic processing might represent such a mechanism
the identification of tissue-specific proteolytic processing of Ac45
and the availability of Voa1 mutant yeast as valuable model to further dissect the individual functions of Ac45 will facilitate future research to understand the functional roles and isoforms of Ac45 in the immune system
muscle and brain and its relation to the V-ATPase in human
Screening for abnormal protein glycosylation in plasma of patients with hepatopathy and immune dysfunction with or without neurological symptoms provides a rapid way to identify additional individuals with ATP6AP1 deficiency
Genomic DNA was extracted from fibroblast pellets or white blood cells from 10 patients and available family members. Primers (Supplementary Table 4) were designed to amplify the 10 exons of ATP6AP1 (GenBank accession number NM_001183.4)
including at least 50 bp of the flanking intronic regions

Ensuring a smooth and comfortable experience for passengers has long been the key for major airports looking to differentiate themselves
Ross Davies talks to Marianne van Scherpenzeel of Amsterdam Airport Schiphol – long considered a front runner in the field – to learn more about the initiatives it has in place to slake the demands of the modern traveller
It might be the length of the queue at the check-in desk
the number of boutiques or even the softness of the seat in the departure lounge
but the gamut of metrics that constitute passenger satisfaction at the world’s busiest airports is steadily becoming more complex
The days when an airport simply represented a transient transportation hub are long gone
By dint of the burgeoning airport city concept – identified by TIME magazine in 2011 as one of the "ten ideas that will change the world" – today’s terminals are just as likely to house offices
hotels and high-end restaurants as they are standard currency exchange and car rental desks
Today’s customer-service-savvy passengers are also a lot more exacting when it comes to expectations of what a desirable airport experience should entail
While a swift check-in and shorter wait at the baggage carousel remain paramount
comfort and leisure facilities are arguably just as highly valued by passengers
particularly as a means of offsetting the potential itchy feet and lengthy waiting times synonymous with air travel
with a turnover of approximately 50 million passengers each year
Amsterdam Airport Schiphol has long been considered something of a pioneer: it is set on shifting the image of a modern airport away from a necessary evil and towards a situation in which passengers are actually happy to spend prolonged periods of time
it has been declared Europe’s best airport at both the Skytrax World Airport Awards and ACI Europe Best Airport Awards
Manager policy and projects Marianne van Scherpenzeel argues that these accolades have come about as a result of ongoing efforts to improve passenger processes and experience
such as the revamp of one of its departure lounges and the roll-out of self-service technology in its check-in areas
"We have done several things over the latest period," she says
"One of those was to update lounge three
The addition of new shops and refurbishments has completely transformed the waiting experience
We have also installed self-service drop-off points for several airlines so passengers can check in their baggage independently."
Don’t let policy changes catch you off guard
Stay proactive with real-time data and expert analysis
Self-service at airports is a trend that has gathered speed in recent years
the usage of which has grown steadily in recent years due to their manifest popularity with passengers
particularly to the baggage drop-off machines," she claims
"As well as adding speed and mitigating waiting times
the advantage of self-service is that passengers can remain in control of their own baggage processes
Schiphol has long valued technology as an indispensable asset in facilitating various passenger procedures
it became one of the first airports in the world to introduce millimetre-wave security scanners – eschewing arduous metal detection gates – while it has also made use of iris scan technology at its border passage since 2001
"It’s really important to pursue innovation
especially if it helps us to add more speed
comfort and control to passenger processes such as checking in and baggage drop-off," says van Scherpenzeel
"We are still looking to develop even more self-service processes
as well as improving the ‘no-queue’ concept
which is an automated border control passage developed in collaboration with the government
We also have a mobile app through which passengers can check their flight information."
airports such as Schiphol have also ramped up their interaction with passengers in order to gauge overall satisfaction levels
the airport is appreciative of the rising influence of social media as a forum where passengers propagate opinion and word of mouth – both positive and unfavourable
"We still conduct a bi-monthly survey
using a broad passenger questionnaire on a number of quality items in order to gauge their overall perception of the airport," explains van Scherpenzeel
"But we also monitor Twitter and Facebook to see what is being said about us and how we can improve our quality."
Schiphol will undoubtedly have been buoyed by the aforementioned accolades that have been bestowed upon it this year – "it’s an indication that we are on the right track and motivates us to continue making passengers feel welcome," confirms van Scherpenzeel
A major contributing factor to the airport’s passenger experience offering remains its impressive folio of amenities – in 2011 it also opened a 200m² park
which serves as a waiting area and is complemented by a connecting rooftop terrace
"The area represents somewhere nice where passengers can relax during their stay
especially if they have a longer transfer time between flights," says van Scherpenzeel
"Adding more comfort is certainly a major driver for us."
tourist-friendly facilities – it also has a library and a Dutch-themed museum – make it a stand-alone airport in many ways
they clearly cannot come at the expense of efficiency
while essential to the smooth running of operations
Airports are still defined and represented by the staff that work across their array of public service areas
training is required to bolster both hard and soft skills
it is really dependent on the situation," she says
a security agent will receive a different kind of training from one of our floor managers as it’s a different kind of job
hospitality remains the central focus for our staff
a number of masterclasses are provided for them."
Despite being the fourth-busiest airport in Europe
Schiphol currently has the highest peak-hour capacity on the continent owing to its status as a major transit hub
And with passenger volumes expected to increase in the future
there will be an onus on the airport to maintain the high levels of satisfaction to which passengers have become accustomed
will necessitate a creative and far-sighted approach
"We will try and stay as innovative as possible," she says
"This will require us to keep abreast of what passengers want and continually improve the overall process
we hope to remain Europe’s preferred airport."
Given the developments over the last year – recognised by passengers and the industry alike – this goal would appear to be more than achievable

We focus on the greatest sustainability challenges across all sectors
Offering unparalleled depth and breadth of expertise
In this follow up to our most recent edition of the SustainAbility Institute by ERM's annual Sustainability Trends Report
we explore the sustainability issues and trends shaping the business agenda in 2022 from the perspective of the technology sector
The supplement focuses on the five environmental
and governance (ESG) related trends we anticipate will most impact the industry:
The ESG risks and opportunities facing the tech sector are striking
While for many sectors COVID-19 has posed significant challenges
for technology it has also opened numerous new opportunities
the sector has experienced significant growth as people and businesses were forced to go online and rapidly embrace digital solutions to continue economic
and welfare activities when lockdowns were introduced across the world
Pandemic-initiated growth is likely to continue
as remote working and many other uses of technology to connect people in more innovative ways are likely to stick long term
The pervasiveness and ubiquitous nature of technology also means it faces regulatory and civil society scrutiny in areas like data ethics
Edelman’s 2021 Trust Barometer shows that public trust in the sector is waning; in fact
while trust in business overall is growing
trust in the technology sector has consistently declined over the past decade.2 The sector has high-profile environmental challenges as well
the sustainable sourcing of critical minerals
The technology sector has great potential to help society and other industries manage the transition to a sustainable economy
especially considering the sector’s exponential growth
Tech companies already provide technological solutions to other sectors to support their transitions to sustainable operations
If the sector can build and maintain public trust regarding data privacy and digital innovation – so that more digitally enabled solutions can be embraced in everyday lives – then the low-carbon transition can be a digitally enabled one
Learn more about these five sustainability trends
and what companies might expect to result from the trend as the decade advances

Interview with Dick Wittenberg (Dutch journalist and writer) about his career and ambitions
Dick Wittenberg (1953) is a Dutch journalist and writer
His ambition to write started when he was about seven years old and the urge never stopped
after working for 30 years as a journalist for several newspapers
he decided to focus more on writing non-fiction books
This resulted in three books: Prikkeldraad (Barbed wire) 2015
Het gezicht van armoede (The face of poverty) 2015
The last book was crowned with the Bob den Uyl prize and the Dirk Scherpenzeel prize
He now works as correspondent ‘worldsavers’ at the online journalistic platform The Correspondent
It was early in life that Wittenberg knew he wanted to become a writer
Although his dad passed away when he was still young
Wittenberg remembers sitting beside him in the living room watching him write
From that moment on he wanted to become a writer too
As his dad was an accountant it seems more likely that he was noting numbers instead of writing stories but these domestic scenes resulted in Wittenbergs desire to become a writer
In the assumption that writers and journalists were the same thing he left for Utrecht to study journalism
The educational innovations of the seventies that implied democratization of education did not work well for Wittenberg
the project based subjects and excessive freedom did not give him the descent foundation he would have liked
What did help to gain writing skills was his range of correspondence friends that made him write six to seven letters a day
But even though his study didn’t provide him with a good set of skills he never worried about getting a job
He just wanted to get started and learn the profession by experience
He returned to Eindhoven and applied for the first job he could find from there on he applied for other jobs
Wittenberg ended up at the Institute of social research for Surinamese
Maybe this is where his affection with minorities started but because of an incident with corrupt management this job ended
A while after the resignation he started at NRC Handelsblad as a correspondent Eindhoven
It seems characteristic for the unruly attitude of Wittenberg that he moved to the sports department when he wanted something else
In the time the department was highly unpopular and conservative
Because he wasn’t interested in just reporting games he shone a new light on the department by publishing background stories of sportsmen and analysing sports behaviour instead of just reporting a match
Due to the NRC Handelsblad he also ended up as a reporter in London
In the contrary of his preference to be situated in a place in the shadow he was now staged in the spotlights
This pressure weighed heavy on him; besides long working hours and a baby at home
he felt the responsibility towards his paper because of the enormous financial outlay for his correspondence. With unstable politics and the death of princess Dianna it were tempestuous times for England and consequently also for Wittenberg
Publishing everyday worked addictive and ego flattering but eventually also caused a burnout
‘Publishing everyday worked addictive and ego flattering but eventually also caused a burnout.’
When he returned to the Netherlands he could start as an editor on the foreign department focussing mainly on Africa
Although he never thought of it himself, it appeared to be spot on
In this position he could fly to Africa four times a year
write background stories while not being obligated to bring the daily news. Obviously he mainly visited countries nobody was originally interested in, and reported stories that would otherwise not be told
But the times are over that newspapers had the financial resources to fly reporters all over the world several times a year. As we come to talk about contemporary journalism and how digitalization influenced journalism does Wittenberg make clear that he doesn’t see a substantial difference between pressed or digital journalism
But he does observe an increasing level of snack-content in articles
I'm not sure if he is joking when he talks about some contemporary journalist as ‘modern vampires’
By this term he means journalists who are reporting gossip and celebrity news instead of covering the role of a trustable guide
The ideas for his books were born during his last years of employment at the NRC
Because of a shrinking budget there was no money available for thorough research and long background stories
But Wittenberg stayed occupied with his ideas and decided to quit his job and become a freelancer
With some rough ideas for his books he found a publisher and raised the necessary funds
This way he created a particular certainty for himself and enabled himself to become a book writer after all
Simultaneously Rob Wijnberg started the online platform The Correspondent and Wittenberg decided to join on a freelance basis.
The research for his books turned out to be a fantastic experience for him
In the contrary to writing for a newspaper he experienced the freedom to follow side-tracks and didn’t feel the pressure of tight deadlines
For his book Prikkeldraad he visited the place in America where barbed wire was invented and ended up in an elderly home that was funded by money made in the barbed wire industry
This home fascinated him so much that he stayed there for almost his whole stay
His eyes twinkle when we talk about his ‘barbed wire journey’
Wittenberg wants to create decent and enjoyable pieces of writing and by doing so he wants to contribute to society
Later it becomes clear that twinkling eyes are the highest profit you get from publishing non-fictional books about subjects most people walk past. His previous books were on the Malawian village Dickisoni that Wittenberg follows for over 10 years
The daily poverty that is normal to half of the world’s population
The connection between this village and Wittenberg is strong and he tries to return every year
He sais that it keeps him grounded and reminds him to all that is good in life
It’s one of the greatest privileges of his career that he was able to travel so much for his work and is accepted in a culture that is so different from our own
When I ask about the origin of his engagement to minority groups and subjects Wittenberg refers to his youth
Because of the choices and support of his mom he was able to escape this milieu but never forgot where he grew up
He always stayed connected to minorities in the shadow of society
But this is not the goal of his writership
Wittenberg wants to create decent and enjoyable pieces of writing and by doing so he wants to contribute to society Additionally he emphasizes that he doesn’t want to write about celebrities and superficial media events
He prefers to write background stories that the reader doesn’t read every day and in doing so enlighten people and events that are usually left aside
In his writing Wittenberg doesn’t necessarily looks out for stories; he comes across subjects that interest him and keeps an archive
(A small part of this archive is displayed on the title photo.) He later states that he doesn’t see himself as a journalist but more as an archivist
Now he becomes older he also likes to share his knowledge with young journalists and likes to mentor writers with ambition. After his books he decided to put his writing on the back burner but if it’s up to him he keeps writing and collecting stories till the end
Our newsletter arrives every Monday with fresh reviews
Formed in the Nethrlands back in 1972 by keyboard player Ton Scherpenzeel
progressive rock band Kayak have run a course of highs an dlows over a career that spans 45 years
After a three year break they’re back with an almost complete line up and their 17th album – Seventeen
We had the chance to chat with founder the and one constant of the band
LOUDER THAN WAR: First question from me is that having been active band for 45 years
I’m ashamed to say that the new album is the first of yours I’ve heard
How come you’ve managed to steer under my radar for so long
LTW: It’s been quite a journey with all manner of ups and downs
but can we focus on a couple of stops on the journey
Signing with a major label like EMI in the early days must have been a massive boost
when you’re twenty and a beginner in this business
it is all just as exciting as it is ‘normal’ to get a major record company like that interested
You have no idea what you’re up against
the sacrifices that have to be made and the chance of really becoming a success with something you started because it was your passion
That’s great when you’re twenty and naive as hell
and you sort of expect the world to like you
LTW: What was behind the reunion in 2000 after the split in 1992
Or was it a ‘split’ or just a break…
TS: We always made the joke about ‘we have waited till the kids grew up and moved out’ but really we did not think about doing anything with Kayak for over fifteen years since 1981
Until Pim and I found each other again in a creative way
We wouldn’t have used the name while he was still alive- not that he had any rights but he was just crazy enough not to accept Kayak going on without him
Still it took a couple of years before it actually happened as no major record company was really interested to begin with
you must have seen a few changes in the music industry – which do you see as the biggest changes and what are the challenges in making music in 2018
TS: In all sorts of ways I would say the transition from analog to digital made the biggest difference
but on the other hand it is much cheaper to make an album
It is difficult to make some money in the business
while on the other hand the number of acts
bands and artist that all want a piece of the cake has grown immensely
In the past you would hear or read the odd review
reviews from all over the world are pouring in
One fart in Holland and they smell it in Australia
The big challenge I would say is to stand out amidst that all
LTW: You’ve recorded a real variety of music from rock operas to female vocalists
which area do you think you work best
and think I have the ability to write both shorter songs as well as longer epics
or music that belongs in a certain framework and story like rock operas
the theatre-like stuff as well as intimate ballads or out-of-the-box music
The problem with rock operas is usually about the money if you want to do it properly
LTW: You seem to have been dogged with all sorts of struggles
deaths and departures but resolutely carried on – how do you feel these issues have affected the band
TS: Sure how could it not affect you or a band
Ultimately it lead to a band that has me as the sole survivor
Life is all about changes and Kayak is no exception
LTW: And although you have these guys in the band
so what sort of input do they have when it comes to recording
LTW: About Andy Latimer’s contribution to Ripples On The Water
Did you have him in mind to actually play on that track
from the beginning I knew he would have to play it
And I am very fortunate that he wanted to do it
recognizable like only the real great players are
He plays one note and you instantly know it is him
We have kept in touch throughout the years
For some mysterious reason it never happened
LTW: How did the association with Inside Out come about
I know Thomas Waber has his finger on the prog pulse….
TS: We already offered Cleopatra to InsideOut
Arjen Lucassen gave me the tip to contact Thomas
But they weren’t really into this sort of thing
maybe it was too much musical-like for their taste
When our manager Rob Palmen sent them the demos for Seventeen
it is much more of a rock band now compared to the rock opera idea of Cleopatra
I guess you’re always enthused about new material but how do you think the new album sits with in the Kayak catalogue
it is too fresh still and I could not say where it fits in
People say it’s the band going back to the seventies
LTW: And finally – Record World in the USA made you ‘Most Promising Band of the Year’ in 1977…forty years on
If the promise was that we’d conquer the world (or the US at least) and sell many albums
If the promise was to stay true to ourselves
Often things went wrong at the wrong moment
If your singer decides he does not want to sing while a US tour is in the making
If two of your singers decide to leave while you’ve got a rock opera written with them in mind
co-producer and co-writer dies in the middle of a tour
I have always been able to make a living out of my music outside Kayak

It should be noted that the Quinto Elemento team won the previous two tournaments and will seek to secure a perfect performance
a member of Camel and the founder of prog/jazz band Nathan Mahl
has succumbed to kidney cancer at the age of 54
LeBlanc's passing was confirmed by the official Camel website
"It is with a hugely heavy heart that we announce the gentle passing of our friend and keyboard player
We are unable to adequately express the sorrow we are experiencing at this time
Joining the band in 2000 as a replacement for departing keyboardist Ton Scherpenzeel
LeBlanc toured with Camel and was featured on their 2002 release A Nod and a Wink
He was forced to take a leave of absence prior to the group's 2003 farewell tour
but was back in the lineup for their Retirement Sucks tour in 2013
and appeared on 2014's live DVD In From the Cold
Camel's renewed activity came as LeBlanc was battling the cancer that would ultimately claim his life
and he was forced to sit out the band's 2014 live dates
manage to complete work on a new Nathan Mahl album
According to LeBlanc's Facebook page
he passed "peacefully at home in Kemptville
with his wife and daughters," leaving behind "a legacy of beautiful and inspiring music – music that tells a story and each story exposes a search within for the answers to life and art

LeBlanc's passing was confirmed by the official Camel website
According to LeBlanc's Facebook page
In 2021 Kayak released their 18th album Out Of This World
they didn't realise it would be their final farewell
There haven’t been too many reasons to be cheerful for musicians in the 2020s so far. But Ton Scherpenzeel, founder member of Dutch prog mainstays Kayak
That’s not the result of enforced isolation
Rather it’s an upbeat attitude that’s been reinforced through the relentlessly turbulent history of a band that have released their 18th studio album and are approaching 50 years since their original formation in 1972
The most recent tribulation to confront them could have spelled the end not just of Kayak but of their driving force
Keyboardist and songwriter Scherpenzeel suffered a heart attack in 2019
which forced him to re-evaluate his lifestyle as well as his attitude to his art.
“It made me realise how precious life is,” he tells Prog
fair-haired 68-year-old looks sprightly enough on the other end of a Zoom call
I’m not going to make another 20 albums
So now I’m approaching every album as if it’s the last
I’m as dedicated to this one as I was with the first one
I’ve learned not to trust my body anymore
I’m not an excessive drinker or smoker
So I’m walking every day for an hour
I like playing piano and normally that’s enough movement
But my attitude has changed because I still want to go on for a little while yet…”
It’s arguably the best they’ve made since Scherpenzeel reformed the band at the turn of the millennium after their initial 1982 split
And although the current line-up sees no fewer than four members take the lead mic at certain points
Kayak have long since moved beyond being a band of one voice
is a group whose lead singer has regularly switched
amid personnel changes resulting in no fewer than 19 former members being listed on their Wikipedia page
Kayak forged a role at the forefront of the Dutch prog scene in the early 70s after teenage friends Scherpenzeel and drummer Pim Koopman put a band together with Max Werner on vocals
Johan Slager on guitar and Cees van Leeuwen on bass.
Koopman left in 1976 suffering from respiratory problems
their sound had evolved into a noticeably more radio-friendly AOR style
always a reluctant singer and troubled by stage fright despite his striking tenor voice
pulled a rare move known in the trade as “a reverse Phil Collins” by switching from lead vocals back to the drum kit that was his first love (Werner would return to the mic briefly as part of the 1999 reunion before having to leave after the first tour due to health problems).
That left centre-stage open for Kayak fan Edward Reekers to join the band
and for casual observers he’s probably the most recognisable face by virtue of arriving just in time to front Kayak’s biggest hit
The group split in 1982, and Camel fans may remember Scherpenzeel’s subsequent tenure alongside Andrew Latimer and co in that band
but after a one-off live show for a Dutch TV show in 1999 Kayak decided to reform
with former Vandenberg man Bert Heerink replacing the ailing Werner up front a few months later
only for Reekers to rejoin again on vocals in 2005.
who injected a new dimension into the Kayak sound as an additional lead singer from 2003.
This second coming of Kayak saw them increasingly explore their progressive roots with Scherpenzeel’s classically influenced keyboards and fascination for myths and legends returning to the fore on albums such as 2003’s Merlin – Bard Of The Unseen (a more successful
proggier reworking of 1981’s Merlin album with new tracks added)
and the multivoice rock opera Nostradamus: The Fate Of Man in 2005
Readers should expect the unexpected in this band
co-founder and key songwriter Pim Koopman died suddenly of a heart attack
it was really up to me whether the band would continue or not,” says Scherpenzeel
“because we started the band together
And in the end what kept me going – still keeps me going – was the endless drive to create
It’s not like I want a band because it’s so cosy and nice playing with people
It’s a drive to create something that wasn’t there before.”
crowdfunded rock opera Cleopatra – The Crown Of Isis suggested the post-Koopman Kayak still had plenty of creative potential
Scherpenzeel was stunned to learn that both the band’s singers
we had troubles in the band,” he says
“It took me two years to get myself together and convince myself we should continue
He ended up recruiting a whole new line-up in 2017, who would make the following year’s Seventeen album
the highest placing they’d achieved since 1980
The only way was surely up… then came not only the aforementioned heart attack but a global pandemic
sweeping touring plans off the table and giving him further pause for reflection
with actions and consequences that touch us all.”
he’d already bounced back from his near-death experience and written much of the new album
including the title track of Out Of This World
a storming prog tour-de-force geared around a brilliantly baroque quasi-classical synth motif
Its lyrics would soon take on extra layers of resonance as much of the planet locked itself down.
‘Why don’t we get out of this world and fly to a place we could live in?’ Kayak’s (relatively) new frontman Bart Schwertmann sings
It speaks of a wanderlust and the search of relief from a screwed-up planet
“It’s a theme that’s been in the back of my mind for a long time,” Scherpenzeel says
"In fact it actually quotes a song of ours from 1975
‘Remember Noah wrought his ship a long
long time ago?’ It’s about a man who takes off in a spaceship with a selected few
but it’s the same idea with this new song
the desire to escape the world’s problems
Corona hits and it seems to fit even better to the current times…”
Elsewhere on the new album the styles diversify considerably: the short
is funk-inflected soft rock that has a distinctly 80s feel
Cary is irresistible accordion-led folk-pop and Kaja is a transcendent instrumental passage that’s a sublime showcase for the emotive melodic strokes of new guitarist Marcel Singor
the rich banks of harmonies characterising Mystery recall Asia or Yes at their most accessible
the irresistibly bombastic Under A Scar feels like an emotional high point of a rock opera yet to be written
slow-burning nine-minute fable A Writer’s Tale is imbued with bewitching pomp rock melodrama
and Critical Mass adopts an breathless time signature to hopscotch around another beguiling Scherpenzeel piano riff and gnarly
what strikes the listener right away is the immediacy of the songs – with hooks
riffs and instrumental flourishes demanding attention at the first time of asking.
“It’s natural to me,” says Scherpenzeel
I have to grab the listener quickly.’ I’m always trying to make every song stand out
But those come out naturally in the way I write.”
Another stand-out upbeat track is Traitor’s Gate
a gutsy rocker geared around a stabbing central riff and a theme of romantic treachery
Given that it’s preceded by a bittersweet ballad
are we to deduce that Scherpenzeel has had to deal with heartbreak as well as a heart condition?
thankfully I’ve been married 45 years this year
so it’s not really personal,” he smiles
it all stemmed from coming up with that title
where I noticed the Traitor’s Gate sign
I had the title and then I put myself into the role of the person in the song.”
Traitor’s Gate was co-written and sung by top session drummer Hans Eijkenaar (who departed with the Reekers/Oudshoorn-led line-up and later rejoined)
Singor and Swedish former Pain Of Salvation bassist Kristoffer Gildenlöw
Scherpenzeel now feels galvanised by his band.
“I’m lucky to have such fantastic players and singers around me,” he says
“I’m so fortunate to know they are willing to work weeks and months on this album and do their thing
but then you have to find the right people who want to play it.”
“It was inspired by losing David Bowie
then every year it gets more as everybody’s ageing
Later in the song I wanted to make the point that it’s gonna happen to us all
it doesn’t matter if you’re famous or not
We can’t expect our heroes to be any different
Assuming Scherpenzeel’s conservative estimate is right
and he’s not likely to make another 20 albums before he joins the great rock’n’roll hall of fame in the sky
we can only hope he sticks around long enough to make a few more records as good as Out Of This World
he might have the same band alongside him too
But maybe that’s asking a little too much.

Wnt-induced β-catenin-mediated transcription is a driving force for stem cell self-renewal during adult tissue homeostasis
Enhanced Wnt receptor expression due to mutational inactivation of the ubiquitin ligases RNF43/ZNRF3 recently emerged as a leading cause for cancer development
targeting canonical Wnt receptors such as LRP5/6 holds great promise for treatment of such cancer subsets
we employ CIS display technology to identify single-domain antibody fragments (VHH) that bind the LRP6 P3E3P4E4 region with nanomolar affinity and strongly inhibit Wnt3/3a-induced β-catenin-mediated transcription in cells
Structural analysis reveal that individual VHHs variably employ divergent antigen-binding regions to bind a similar surface in the third β-propeller of LRP5/6
sterically interfering with Wnt3/3a binding
anti-LRP5/6 VHHs block the growth of Wnt-hypersensitive Rnf43/Znrf3-mutant intestinal organoids through stem cell exhaustion and collective terminal differentiation
VHH-mediated targeting of LRP5/6 provides a promising differentiation-inducing strategy for treatment of Wnt-hypersensitive tumors
These Wnt-enhancing properties complicate the application of LRP6-targeting mAbs in vivo
we selected three highly potent VHHs that bind LRP6 with nanomolar affinity and efficiently block Wnt3/3a-dependent β-catenin signaling
Structural analysis revealed that these VHHs all bind a surface of the third propeller domain of LRP6 that is likely involved in Wnt3 binding
treatment with anti-LRP6 VHHs induces strong growth inhibition of Wnt-hypersensitive intestinal organoids by driving collective terminal differentiation
we identify a highly potent set of VHHs that target Wnt-hypersensitive tumors
VHHs targeting LRP6P3E3P4E4 block cellular responses to Wnt3a

anti-LRP5/6P3 VHHs effectively target Wnt-dependent tumorigenic organoids by removing an essential pathway for renewal of stem-like tumor cells and promoting their terminal differentiation
From an initial panel of 33 LRP6P3E3P4E4-binding VHHs
we selected three VHHs that most efficiently inhibited cellular responses to Wnt3a at low nanomolar IC50 values
These VHHs efficiently blocked the growth of murine tumorigenic R/Z-mutant organoids
We show that L-P2-B10 employs a particularly long CDR3 loop that interacts with the VHH framework to create a stable flat paratope for recognition of a plane epitope at the center of the LRP6 P3 domain
while CDR1 does not participate in the interaction
L-P2-D07 employs a much shorter CDR3 loop that
interacts with the same relatively flat epitope
This recognition motif is absent in the CDR sequence of our LRP6P3-binding VHHs
in line with their lack of interference with Wnt1-mediated signaling and apparent specificity for inhibition of Wnt3/3a-mediated cellular responses
due to conservation of the VHH-binding epitope on LRP5P3 and LRP6P3
allowing for selective blockade of Wnt3/Rspo-mediated cellular responses while leaving non-blocked Wnts unaffected
The broad species cross reactivity of these VHHs as anticipated based on in silico modeling of the contact surfaces (rodent
non-human primate) should facilitate both therapeutic proof-of-concept experiments as well as toxicology studies

They decided to take up this challenge after their existing clientele expressed a clear need for an additional screen supplier
Ridder started to explore the opportunities and we soon realized these existed."
a start was made at the time to develop an extensive portfolio
“At that moment the portfolio was still far from complete
but we did have a number of good products to enter the market with
It was a good time to introduce a new supplier.”
Ridder started with twelve screens - all available from stock and in three different sizes
Now seventeen types of screens are supplied from stock and the complete assortment consists of more than thirty types
including screens produced entirely in the Netherlands
Co-creationLast year Ridder started with "co-creation"
In addition to the already existing screens
operational director: “Together with the customers
we develop a variant that meets their specific wishes and needs
This way we contribute to the solution to the challenge that our customers face in their project
supported by the existing knowledge and experience within the Ridder Group
A great development that we are proud of.”
In addition to the introduction of new and co-created screens
Ridder is constantly looking to optimize the current screens
we are investigating how we can achieve higher energy savings with our energy screens
for example by increasing the thickness of the foil
But we always keep looking at the net return
When we compare the additional costs of such a new product with the advantages
we still have to conclude that we have the ideal mix with the current RES 10 FR screen
That is also an outcome of a development.”
Mario ScherpenzeelNiels and Johan tell about the knowledge within Ridder
they would not be able to realize new developments
The foundation of this knowledge was laid by Mario Scherpenzeel
Johan: "The professional and stable base that he created within our department ensures that there is now an incredibly good team that is ready to go through."
Niels also agrees that this foundation is very important to Ridder: "Thanks to the foundation that Mario laid
the team can now continue to develop with enthusiasm and energy."
Present situation Ridder has already delivered more than 4000 ha of climate screens
Last year Ridder reached a milestone by supplying 1500 ha in the Netherlands
There are now four knitting machines at the production location in Maasdijk
there is no intention to bring the total production to the Netherlands
“The most important thing is that production in the Netherlands is going to provide us with a lot of knowledge and experience
This makes us less dependent on our partners in Asia
It also ensures that with our production we are closer to the customer
“It is now also possible for our customers
to come and view the production of their screen,” says Niels
“Our department now consists of eighteen employees
Most people will know my colleagues Joachim Keus
And of course we can always use new people
Bright futureWith the celebration of the fifth anniversary
“We have now positioned ourselves well in the market
We have made progress and are developing new screens ourselves,” says Johan
Ridder would like to make the difference in the current market over the next five years
Five years plus one“The invitations had already been printed and we had made many arrangements,” Johan laughs
But then he says: “Delay does not mean cancellation
If the current circumstances do not make it possible to celebrate this year

a dedicated photographer from the Netherlands
has been able to wholeheartedly document the early stages of Sultanate of Oman’s renaissance
He recently offered his exceptional collection as a special gift to Oman
based on his deep love for the country and on his keenness to enrich its national archives
his collection illuminates this pivotal era of Oman’s modern history
which he collated with the earlier one under the title “Oman
Scherpenzeel said that over the past four years he spent in Oman in the early 70s
he was able to document a large number of scenes
scenery and landmarks of Omani governorates that reflected the social
cultural and human heritage of the country
Oman has seen a comprehensive transformation
thanks to the country’s ability to keep pace with the events of the age as they unfolded
Scherpenzeel said that photos are more truthful in projecting reality at a time the rhythm of life is changing at a rapid pace
crisscrossing with all aspects of social interactions
He affirmed that he was already in Oman by June 1970
three weeks prior to late Sultan Qaboos Bin Said’s accession to power in the country
“Life in Oman was marvelous and Omani people were gentle
sociable and truthful in their friendship,” said Scherpenzeel
noting that one could move freely in the fascinating landscape and that one could even sleep safely on the golden dunes
Scherpenzeel said he could still remember his visit to Sur and the long trip to the easterly wilayat from Muscat by 4-wheel on the rough roads
he could observe Omani people’s devotion to the Islamic religion and sound Arabian habits and traditions of hospitality
Oman’s Ambassador to the Netherlands
said that these sincere reflections represent a model of the Sultanate of Oman’s soft power that distinguishes Omani people among nations of the world
when he visited Scherpenzeel at his home in the Netherlands
he was astonished at the man’s amicable reaction
“It was as if he had known me for a very long time
His warm welcome unveiled his deep love to Oman and his thorough knowledge of the country
the reputation of its people and the grandeur of its leadership.”
Many things struck me as I entered Scherpenzeel’s home: Every corner is adorned with an image from Oman
his bedroom is bedecked with historical paintings
What baffled me more was the fact that Scherpenzeel made accounts of Omani villages and countryside in such details that gave me the impression that I was listening to an academic in Omani history and civilization
The ambassador explained that he visited Scherpenzeel to thank him for the gift he presented to the Sultanate of Oman and to express gratitude for such a humanitarian gesture

Kayak have announced their farewell tour which is set to take place in April & May 2022
These shows will see them perform tracks from across their career
Band lead Ton Scherpenzeel comments “It’s been a great ride but we’ve come to the end of the line
As the other band members would have liked to continue
But it takes a lot more than just that to make a good tour and circumstances for bands like us are not getting any easier
In that respect I feel I’ve reached the limit of my capabilities
I’d rather stop too early than go on too long.”

Netherlands-based meat business Vion Food Group is investing in a plant in the south of the country as part of a consolidation process
Netherlands-based meat business Vion Food Group is investing in its plant in the town of Boxtel as part of a consolidation process
Vion plans to spend EUR35m (US$39.6m) to modernise the facility in “order to further increase its competitiveness on the national and international meat markets”
according to a statement posted on its website.
Some of the fresh meat production carried out at the company’s site in the town of Scherpenzeel
located in the Dutch province of Gelderland
will be transferred to Boxtel in the south of the country
Vion said the “majority” of the 120 workers employed in the fresh division at Scherpenzeel will be relocated to its other factories in Boxtel
or “will leave by means of natural labour turnover”
Around 20 workers may not find relocation a suitable possibility
It expects to complete the transfer by the middle of 2021.
Vion noted the operational transfer “will shorten the supply chain
which will result in an improvement in the quality and freshness of the meat and more efficient production”.

Experts stressed the importance of standardisation, data sharing and transparency at Riviera’s webinar, Voyage and vessel optimisation when making port calls
Icelandic maritime energy management provider Marorka’s director of service
International Taskforce Port Call Optimization chairman Ben van Scherpenzeel
PortXchange international business consultant - port call optimisation Captain Abhishek Nair
and Shell general manager shipping & maritime for Europe & Africa
Captain Kaia Bjerre van de Ven discussed issues related to the future of data sharing and digitalisation in port operations
Mr Björnsson said real-time optimisation was made possible when vessels were able to receive real-time weather and sea-state forecasts and terminal data. While improvements in connectivity and modelling have helped Marorka provide customers with efficient speed profiles for voyages
Mr Björnsson said the question of data sharing remains an issue
He suggested the industry needs to have standards in place for data sharing and must incentivise companies to share operational data
Mr van Scherpenzeel said data sharing is burdened by the differing standards and formats present throughout the industry
While standardisation will require co-operation
investments in implementation and cultural change
Any data sharing process has to be applicable geographically as well as across operational types and profiles
Mr van Scherpenzeel explained berth planning in the context of vessels and ports that are not linked by a central database
Most ports are run by a public body while the terminals are managed by private organisations
“Berth planning is dictated by a terminal
The access to the terminal is through a public waterway
normally organised by the public authority with the help of a service provider for nautical services
That collaboration is key to our customers who arrive at the port," he said
terminals and service providers to realise one planning system that allows ships to arrive at port at a safe
Citing a practical case of a mariner receiving conflicting navigational data
Captain Nair showed how this could lead to efficiency losses throughout the supply chain
the data [a mariner] has on [a] chart or publication does not match the information [he or she is] getting from the port authorities or the agents
just a difference of 10 cm between a chart and the port’s data can mean a loading difference of 2,000 tonnes on a VLCC
And as a master you will probably err on the side of safety," he said
Noting the delays and costs incurred due to a lack of data sharing, Captain van de Ven said "shipping is not linear; sharing data helps us react at any time"
“We still see container vessels up to 20,000 TEU waiting for bunker barges that are delayed
This is about being aware of how different parts in the chain are active,” she said
Captain van de Ven said she expects standardisation will be driven by IMO
and supported by industry bodies like BIMCO and Intertanko
The experts also pointed out it is important to incentivise change in addition to creating a standard
Noting that “incentives work better than regulations” Mr van Scherpenzeel said by modifying contracts
masters can be incentivised to share data without fear of breaching the contract
Captain Nair said the process involves changing work culture and that PortXchange is conducting an ongoing pilot programme with chemical clusters in Houston
Recognising that companies have widely varying levels of digital maturity
he said “You have to work with them slowly
find what works best for each user and finally bring them towards one common standard.”
Mr Bjönsson said Marorka places emphasis on a practical approach
He said performance management has benefited from increased transparency between owners
charterers and managers and is expected to be useful in vessel optimisation
standards alone cannot improve performance
Decisions made on bad data have the potential to be worse than decisions made on gut feeling."
Captain Nair said existing data can be used for optimisation
stressing the need for more willingness within shipping to adapt to new technology
We want things to work right before we step into it
Let’s try to make this digitalisation journey together."
Some 74% of webinar attendees felt that current regulations encourage digitalisation and 43% agreed with our panel that willingness is the biggest barrier to further digitalisation in the industry
73% of attendees said their company has a clear idea of digitalisation in the coming years with 39% suggesting there is a clear roadmap for the next five years
A strong majority at 80% said they expect to see full IoT connected vessels between 2025 and 2030

Muscat – Dutch photographer Eric van Scherpenzeel
who documented the beginning of Omani renaissance from 1970 to 1974
recently presented his photos as a gift to the sultanate
The photos captured an important stage of modern Omani history for posterity
Scherpenzeel spoke of he great love for Oman and its the beauty
and hence his decision to gift these to the sultanate
He visited Oman for the second time in the 1990s to photograph specific areas
which he recently published as a comparative study in a book titled Oman’s Past and Present
features and various details reflecting social and cultural aspects of Omani people across several governorates,” he told ONA
three weeks prior to the Late Sultan Qaboos bin Said’s accession to power
“Life in Oman was marvelous; the people were gentle
sociable and truthful in their friendship,” said Scherpenzeel
adding that visitors could travel in the fascinating landscape at will and sleep safely on sand dunes under stars in the desert
visited Scherpenzeel at his home to thank him for the gift
“It was as if he had known me for a very long time,” the ambassador said
H E Dr Harthi was struck by what he saw in Scherpenzeel’s home
his bedroom was bedecked with historical paintings
mementos and even old rifles from Oman,” he said
Muscat Daily is now the largest selling broadsheet newspaper in the Sultanate of Oman with 33,500 daily copies and 28,000 subscribers.

Fiber Nederland (Fiber NL)
a provider of triple play and smart home solutions
is acquiring its competitor Stipte (formerly Scarlet Netherlands)
which was founded three years ago by Martijn van Scherpenzeel
and operates independently of network operators
“Between powerhouses such as KPN and Ziggo Fiber NL is a relatively small player
but in a consolidated market competition has generally more to lose than to gain
service-oriented and able to react faster to trends.”
Van Scherpenzeeland points out that for instance Fiber NL beat KPN in 2015 by being the first to offer an integrated smart home solution
The company also took a majority stake in the technology company that offers the Smart Alarm home automation services
Van Scherpenzeel added: “With the acquisition of Stipte
known for its operational excellence and its organisation and brand fits well with Fiber NL
we hope to expand our role as a challenger
We are pleased to welcome Matthijs Kamp as a partner and collaborate with an enthusiastic group of professionals
This acquisition has no impact on staffing and delivery of services to customers of Stipte.”

set a target for his business to have zero impact on the environment by 2020 many thought it an outrageous ambition
But the company has made such great strides that
its European operations are within touching distance
At a time when very few companies were making public commitments to sustainability, "mission zero" was a bold vision
Since then Interface's journey towards sustainability has seen a momentous shift in the way the company operates – and some outstanding results
Interface's plants in Holland and Northern Ireland have been using around 90% less carbon and 95% less water than in 1996
All the gas used here is biogas produced from green waste that comes from a local fish processing company
The gas is produced from the anaerobic digestion of fish waste
which is filtered to the natural gas standard
pumped into the grid and bought by Interface
The switch to 100% biogas has eliminated all energy-related emissions at the plant
which at the beginning of 2014 stood at 8,900 tonnes of CO2 a year
The Dutch facility uses hardly any water in the manufacturing process – the only water it consumes is on the domestic front
Interface's manufacturing facilities use 95% less water today than they did 18 years ago
95% of Interface's energy consumption comes from renewable sources
a massive leap from 2012 when the figure stood at 33%
This has shielded the company from energy price volatility and carbon-related price movements
Interface's facility in Craigavon has used 100% green electricity since 2006 and has recycled all of its waste since 2008
In 2014, the company will reduce its scope 1 and 2 emissions in Europe by 90% from a 1996 baseline
So how has Interface achieved such massive reductions in energy and water use
Meeting the challenge of zero impact on the environment is not about making a few tweaks
an aggressive energy efficiency programme and the technology to go with it
It means an approach to sustainability that influences every aspect of the company's business
inspiring Interface and its people to continually push at the boundaries
This attitude was applauded by the Guardian judges who were impressed with Interface's "clear and determined pursuit of mission zero to realise a radical and transformative change"
One of the innovations that helped Interface reduce its energy use is a new pre-coat manufacturing line
Pre-coat is an important part of the backing that supports the look and feel of a carpet by anchoring the yarn in place – in Interface's case this layer is latex
The new pre-coat line makes more efficient use of hot air through ultra-efficient ovens
cutting gas consumption and dramatically reducing the company's dependence on fossil fuels
the new pre-coat process has reduced energy use by 40% per square metre of carpet produced and cut the use of materials by 8% in the Scherpenzeel factory
It is just one of a wide range of energy-saving measures introduced by the carpet tile manufacturer
more sustainable materials and the installation of LED lighting
many of Interface's savings have come from fundamental shifts in the way it makes its products
The company has also changed the way it operates
A new closed-loop piping system in its Scherpenzeel plant
recycles all cooling and manufacturing water
meaning the only water used by the factory is for domestic purposes
These latest achievements bring Interface closer to achieving its ambitious goal
in 2014 the company's European operations will achieve a 90% reduction in greenhouse gas emissions
That exceeds the EU Commission's proposed 2030 carbon reduction target by more than 100%
Interface is proud of these milestones on its "mission zero" journey
It is the kind of progress that is beyond the imagination of many companies
but for Interface it is by no means the end of the story
"mission zero" is not just about its own operations – it is taking responsibility for the lifecycle of its products
And that is where the carpet tile revolutionaries are going to focus their attention next

The Guardian Sustainable Business Sustainability Case Studies contain articles on all the initiatives that met the criteria for the GSB Awards.
‘The waste processors want to visually check if there’s anything that doesn’t belong in the bags and you can’t do that with the opaque grey bags
If we can’t see what the quality of the material is we can’t process it,’ Rudie Marsman of Van Scherpenzeel recycling firm told the broadcaster
At Van Scherpenzeel two to three tonnes of plastic and metal packaging and cartons (PMD) end up being burnt unnecessarily every year
Waste disposal companies told local councils as early as January that opaque bags containing such refuse are no longer welcome because ‘the assumption is they contain ordinary household waste’
locals authorities have failed to notify the public that opaque bags are banned and transparent bags are now the order of the day
these were issued via packaging industry initiative Plastic Heroes but when local councils took over the collection of PMD waste in 2015 the bags were no longer available
which have introduced containers for plastic or wheelie bins
It should have been explained to the public that the transparent bag served a purpose,’ Marsman told NOS
Waste processing companies are reportedly struggling to process the enormous amount of PMD waste: although more people are sorting their waste
the amount of other refuse in among the PMD waste is growing too
A report by Rijkswaterstaat showed that 21% of collected PMD waste contains items that sorting machines cannot handle, such as food waste, plastic toys, household implements and clothes, NOS writes.

Horizon Forbidden West has been out for quite some time now and one thing is for certain
we are going to have a sneak-peek into a collection of stunning art from the Horizon Forbidden West Art Team
The developers uploaded a collection including early concept art of environment
We will not be showing everything that the team has uploaded for obvious reasons. You can view them in all their glory here
here are some of our favourites from the collection
With a fleet of 200 trucks and three hubs in Poland
which also serve the Slovak and Bulgarian markets in addition to the main location in the Netherlands
Mandersloot is one of the market leaders in conditioned groupage transport to Central Europe
"The advantage of the various depots is that we are locally present and speak the language of the customer
while a branch manager from the Netherlands is active in all countries
we can immediately solve problems with a certain shipment and we offer on the spot services such as stickers
documentation and quality controls," says Willem van Leuveren
frozen goods and so-called high value cargo
"We are a customer at almost all retailers in the mentioned Central European countries
We can therefore apply very competitive rates for retail," says Willem van Leuveren
"We often cross-dock the Dutch products in our logistics centre in Scherpenzeel
the trucks must be on their way to our hubs
so that the cargo can be delivered to the Eastern European the next day
For this we have in-house transport from vans to LHVs
because we are also active in urban distribution and can therefore also cover the last mile
our activities go much further than transport from A to B
the company took an important step in obtaining the IFS Logistics certificate
this means not only a safety system for the transport and cross-docking of food-related products
but it is a system in which we can guarantee the quality of every conditioned product on all fronts," says Willem
"This has also changed things for the customer
They used to be able to choose from various temperature ranges
now they can only choose between four different set points for LTL transport
We drive with these temperatures on a continuous basis
so that there is less temperature fluctuation during transport
Willem mentions the recruitment of qualified drivers as the main challenge
because we always drive with drivers from the country of origin
so from Poland with Polish drivers and from the Netherlands with Dutch drivers." He does not expect that road transport to these countries will be replaced by other modalities
"The network in Central Europe is not suitable for this
and the truck is still the fastest means of transport."
Web portalAutomation is a spearhead for Mandersloot
"Our web portal is available to all customers
so that they can track their shipments and view documents 24 hours a day
We also send our key accounts a performance report every week
but we find it is important to communicate proactively to the customer
There can always be something that slows down the freight
in which I expect that most of the planning will take place automatically within a few years
I do not think that the human factor will be superfluous
but planning will become a different profession
the planners knew all the postcode areas by heart
Nowadays they have to think much more systematically
That is why we also focus on the necessary education and training
"Mandersloot remains a real family business
In 1964 it was founded by Teuni and Wuf Mandersloot
the management is led by Ronald and Marjon Mandersloot and the third generation is already involved in the company," says Willem
"Sustainability is of paramount importance to us
This year we have installed solar panels on the roof of our headquarters in Scherpenzeel
and the purchase of LNG trucks is planned for next year."

Mandersloot will be the first logistics service provider in Europe with 3 LHVs (Longer Heavier Vehicles) on an international route to supply the Czech Republic
specialized in conditioned transport of mainly food
will use the LHVs mainly for the line-haul of groupage goods between the parent company in Scherpenzeel (gld) and the subsidiary in Prague
Sustainability is of paramount importance at Mandersloot
is equipped with solar panels and in addition
several LHVs are already being used for inland transport
sees the deployment of LHVs over long distances as an important next step in the process to reduce the company’s carbon footprint
In addition to its head office in the Netherlands
Mandersloot has several modern premises in Central Europe
Mandersloot is able to supply all major retail organizations in Poland
With a fleet of more than 200 vehicles and a customer-oriented focus
authorities and employees who made this fantastic milestone possible

Kim Carter, a young Dutch gymnast of Maltese descent, yet again played a prominent role in her club's success in the national Rhythmical Gymnastics finals, held recently.
On April 13, Carter and her colleagues had represented their club - GTV de Badhoeve - in the last qualifying round ahead of the main finals.
A fine performance on that occasion earned GTV de Badhoeve the right to compete in the finals last month in Scherpenzeel.
Under the heading 'GTV de Badhoeve - the best Rhythmical Gymnastic Club in the Holland', regional newspaper Het Witte Weekblad reported that Carter and her team-mates produced an excellent performance in the finals, winning three gold medals and a first placing in the overall rankings.
In Category 1B, GTV de Badhoeve was very successful.
In the 'hoop exercise', Sarah Vogel, Tessa Herngreen, Daphne van Delden, Kim Carter, Dominique Corver, Stephanie Klassen and Nikki Wesdorp were the season's favourites for the Dutch title.
Expectations were eventually met as the team obtained 18.392 points to become national champions.
There was stiffer competition in the ribbon exercise but a second and third placing in the qualifying rounds secured a place in these finals for GTV de Badhoeve.
Encouraged by the other successes on the day, the team carried out their exercise almost to perfection and with a total of 15.599 points, they clinched another gold.
Thanks to these fine performances, valuable points were obtained towards the overall standings and rankings. In 2001, GTV de Badhoeve were third but this time around they dethroned former champions Pax Hoofdorp.
GTV de Badhoeve were crowned Dutch champions with 1,753 points, enjoying a lead of 120 points over their nearest rivals.
GTV de Badhoeve are planning a visit to Malta. About 20 to 30 girls will be coming over in October to give a training demonstration at a local club. Carter is currently spending her summer holidays on the islands.
