SMARTAQUA: Acting fast on marine corrosion

Maintenance is not the sexiest aspect of business, but diligent corrosion monitoring in the oil, gas, and maritime industry could prevent massive environmental accidents. Inês Pimparel writes on behalf of AquaBioTech Group.

The maritime industry is going through massive developments. Traditional oil and gas remain powerful, as does the shipping industry, but there is a big rise in more sustainable businesses such as offshore wind and solar energy farms. Corrosion affects them all equally.

The NACE International Institute estimates that corrosion costs the maritime industry between $50 and $80 billion every year. Clearly, maintenance is an expensive practice, which might lead to neglect, resulting in catastrophic environmental incidents. 

A low-cost, eco-friendly, and efficient solution is needed to monitor corrosion and enable earlier repair.

The industry currently monitors structures using ultrasonic or magnetic sensors. However, other solutions exist. The University of Aveiro (Portugal), the Norwegian research institute SINTEF, and the Maltese company AquaBioTech Group are working on SMARTAQUA, an innovative but simple approach that uses a special paint. 

Scanning electron microscope pictures of nanomaterials used in the project.

It uses environmentally-friendly nanomaterials to form a functional solid film over surfaces such as the support for a floating fish farm or the base of a wind turbine. Because the nanolayer goes directly onto the structure, it can combine colorimetric with magnetic analysis to detect corrosion as it happens. 

The detection method will be tailor-made to the depth at which the metallic structure is placed to assess the integrity of the structures. Colorimetric detection is a relatively simple, user friendly, and reliable manner of detecting corrosion in splash zones. But in submerged structures, where colorimetric detection is not possible, the use of magnetic measurements would reveal the state of coated substrates.

The approach is not completely novel. The aeronautical sector is already introducing it. The AquaBioTech Group is performing toxicity tests on the nanomaterials using marine organisms such as microalgae and mussels. After this, the team will test the nanolayer’s efficacy on metallic structures in their offshore testing site close to St Paul’s Islands.

If this technology is proven safe and effective it will revolutionise the field of monitoring activities. It will reduce transport needs when assembling new offshore structures, indirectly reducing fuel use and greenhouse gas emissions. The commercial and environmental benefits are massive.

The project is highly collaborative. It brings together a small business, a research institute, and a university; testament that success can be achieved through co-creation, inclusivity, and sustainability—and that small advances can lead to a sea of change. 

Note: This project was funded by the Research Council of Norway (through the programme of Petromaks II, project 284002), the Foundation of Science and Technology in Portugal, and the Malta Council for Science and Technology via the MarTERA – ERA-NET Co-fund scheme of H2020 of the European Commission.

STEM ambassadors thrashing stereotypes

Over the last four decades, STEM industries have risen to great heights. Scientific, technological, engineering, and mathematical minds have been called to rally. And the demand continues. How can you contribute?

Few would dispute that technological and scientific advancements dominate the 21st century. Adverts provide ample proof. From tablets to smartphones, to robot home appliances and driverless cars, our world is changing fast. As a result, we are now living in a global knowledge-based economy where information can be considered as the highest form of currency. This reality comes with both benefits and challenges. 

Statistics from 2013’s European Company Survey show that 39% of European Union-based firms had difficulty recruiting staff with STEM skills. Malta is no exception. Another report in 2018 showed that people with STEM careers are still in short supply locally, especially in the fields of healthcare, ICT, engineering, and research. So, while the jobs are available, there aren’t enough people taking up STEM careers, and this is holding Malta back. 

There are many reasons for this trend. For one, Malta has a low number of tertiary level graduates; the third lowest in the EU. An array of harmful stereotypes can also shoulder some blame. The ‘fact’ that people in math, science, and technology ‘don’t have a social life’ is unhelpful. The ‘nerd’ image is still prevalent, especially among the younger generations that are still in primary and secondary school. Then there is the ‘maleness’ associated with STEM jobs and industries. According to Eurostat statistics, in 2017, from 18 million scientists and engineers in the EU, 59% were men and 41% women. 

Still, this is far from the whole picture. 

Employers have reported instances where, despite having enough graduates to fill roles, applicants did not possess the right non-technical skills for the job. This was especially true for abilities such as communication, creative thinking, and conflict resolution. 

Many were unprepared to work in a team, to learn on the job, and to problem solve creatively. This is a real concern, especially for the country’s future. At the rate with which markets are evolving, a decade from now young people will be applying for jobs that do not exist today, and the country needs to prepare students for these roles. And it has to start now. 

The Malta Council for Science and Technology (MCST) is trying to do this through an Erasmus+ project called RAISE. They are launching an Ambassador Programme to empower young students to take up the STEM mantle. STEM Career Cafés are going to be popping up in schools all over Malta, alongside a Career Day at Esplora aimed to inform and inspire. This is where you come in.

They want undergraduates from the University of Malta and MCAST to work with Esplora by sharing your experiences in STEM and telling your stories to encourage those who may be considering a STEM career. STEM Ambassadors will gain important public engagement skills while making research and science careers more accessible.

STEM is crucial in our contemporary world; our economies depend on it. It has completely changed the way we live and opened up new prospects for a future we never imagined. For those who have already made up their mind to be a part of it, there is now the opportunity to empower others and guide them in finding their own path. 

Note: To become a STEM Ambassador, email programmes@esplora.org.mt or call 2360 2218.

The MCST, the University of Malta, and the Malta College of Arts, Science and Technology have embarked on a national campaign to promote STEM Engagement. Its first activity was a National STEM Engagement Conference.

We’re exploring Here!

If you had a rich malleable canvas that could flip rules on their heads and expose truths we take for granted, wouldn’t you use it? Jasper Schellekens writes about the games delving deep into some of our most challenging philosophical questions.

The famous Chinese philosopher Confucius once said, ‘I hear and I forget. I see and I remember. I do and I understand.’ Confucius would have likely been a miserable mystic in modern mainstream education which demands that students sit and listen to teachers. But it’s not all bad. Technological advancements have brought us something Confucius could never have dreamed of: digital worlds. 

A digital world offers interaction within the boundaries of a created environment. It allows you to do things, even if the ‘thing’ amounts to little more than pressing a key. Research at the Institute of Digital Games (IDG) focuses on developing a deeper understanding of how these concepts can be used to teach through doing by looking at people interact with gameworlds, studying how games can impact them (Issue 24), and designing games that do exactly that. 

Doing it digital 

Two millennia later, John Dewey, one of the most prominent American scholars of the 20th century, proposed an educational reform that focused on learning through doing and reflection instead of the ‘factory model’ that was the norm. Dewey’s idea was embraced, and has become a pedagogical tool in many classrooms, now known as experiential learning.

Let’s not pretend that Confucius was thousands of years ahead of his time—after all, apprenticeships have always been an extremely common form of learning. But what if we were to transplant this method of experimentation, trial and error, into a digital world?

It would allow us to do so much! And we’re talking about more than figuring out how to plug in to Assassin’s Creed’s tesseract or getting the hang of swinging through New York City as Spiderman. While these are valuable skills you don’t want to ignore, what we’re really interested in here are virtual laboratories, space simulations, and interactive thought experiments.

Games make an ideal vehicle for experiential learning precisely because they provide a safe and relatively inexpensive digital world for students to learn from.

Think of the value of a flight simulator to train pilots. The IDG applied the same idea to create a virtual chemistry lab for the Envisage Project. They threw in the pedagogical power tools of fun and competition to create what’s known as serious games.

Serious games are at the heart of many of the IDG’s research projects. eCrisis uses games for social inclusion and teaching empathy. iLearn facilitates the learning process for children with dyslexia and Curio is developing a teaching toolkit to foster curiosity. However, the persuasive power of videogames stretches further than we might think.

In a videogame world, players take intentional actions based on the rules set by the creators. These ‘rules’ are also referred to as ‘game mechanisms’. Through these rules, and experiential learning, players can learn to think in a certain, often conventional, way.

Which brings us to HERE.

Prof. Stefano Gualeni is fond of using games to criticise conventions: in Necessary Evil a player takes on the role of an NPC (Non Player Character) monster, in Something Something Soup Something the definition of soup is questioned, while in HERE Gualeni breaks down what ‘here’ means in a digital world.

What’s Here?  

HERE sees the player explore the philosophical concept of ‘indexicality’, the idea that meanings depend on the context in which they occur. A fitting example is the extended index finger, which means different things depending on where it is placed and what movement it makes. Point one way or another to indicate direction, place over the lips to request silence, or shake it from side to side to deny or scold. 

The game explores the word ‘here’ in the digital world. It sheds light on how much we take for granted, and how a lot of concepts are not as straightforward as we think. 

HERE you play as ‘Wessel the Adventurer’, a cat of acute perception that is sent on a quest by a wizard to find magic symbols and open an enchanted cave. Playing on the tropes of role-playing games, the expectations of the adventurer are thus framed in a conventional manner, but not everything is as it seems.

By subverting players’ expectations of role-playing games, they will have the opportunity to discover what they have been (perhaps unwittingly) taught. They will be confronted with a puzzle involving the many versions of ‘here’ that can co-exist in a digital world. Among their prizes is Gualeni himself performing a philosophical rap. 

Explorable Explanations 

Experiential learning isn’t the only way to learn, but video games, with their interactivity and ability to manipulate the gameworld’s rules with ease, offer a ripe environment for it. The digital realm adds a very malleable layer of possibility for learning through doing and interacting with philosophical concepts. HERE is not alone in this approach. 

Words often fall short of the concepts they are trying to convey. How do you explain why people trust each other when there are so many opportunities to betray that trust? Telling people they have cognitive biases is not as effective as showing them acting on those biases.

Explorable Explanations is a collection of games curated by award-winning game developer Nicky Case that dig into these concepts through play. The Evolution of Trust is one of them, breaking down the complex psychological and social phenomena contributing to the seemingly simple concept of trust in society. Adventures in Cognitive Biases is able to show us how we are biased even when we don’t think we are. HERE delves into our understanding of language and the world around us, showing us (instead of telling us) that learning doesn’t have to be boring. Now go learn something and play HERE.

Burnout

In airplane safety demonstrations, we are always told to put oxygen masks on ourselves before we help others. If we are not well, how can we help others efficiently? Dr Patrick Barbara writes about burnout among Malta’s mental health professionals and what we can do to resolve this worldwide issue.

Mental health professional ‘Joe’ works in the Maltese hospital’s  services. He feels emotionally drained and at the end of his rope. In the morning, he wakes up dreading his workday. The passion for it has dissipated. Maybe, he thinks, it’s time to quit.

Dr Patrick Barbara

Dr Aloisia Camilleri and I explored the concept of burnout in professionals working within our mental health system. The research project itself was born from the notion that to support those who need care, service providers themselves need to have good mental health. 

To understand job-related burnout, it is best to see it as a spectrum. People can be happy, satisfied, and fully engaged, or they can be completely disinterested and disengaged. This framing helps us understand that there are differing degrees of burnout, while also highlighting that different definitions of burnout can lead to different results.

In our research, burnout was defined as a process where a person’s psychological resources are gradually depleted as a result of prolonged stress at work. This then manifests in emotional exhaustion, depersonalisation, and loss of personal accomplishment. The person feels worn out, fatigued, detached, and cynical about their job. Ultimately there’s a sense of inability to cope, and low morale sets in. This is the ultimate lose-lose situation where both the employee and the patients suffer as the organisation loses efficiency.

For the study, we invited 322 professionals to participate anonymously. The roles they occupied varied and included psychiatry doctors, nurses, occupational therapists, psychologists, psychotherapists, and social workers. In the end, 230 agreed to answer our standardised questionnaires. The results were in line with those of similar studies conducted abroad.

Emotional exhaustion scored highly (40.4% of respondents), as did poor personal accomplishment (30.4%). A fifth (18.3%) experienced high depersonalisation levels, while 13.9% scored high on all three features of burnout.

What causes burnout is complex and difficult to explain. The healthcare environment and the systems operating within it do tend to put healthcare workers at risk. They suffer from time pressures, emotional intensity, role conflict, and difficult relationships between employees and management.

Research suggests that people at risk of experiencing burnout often experience a mismatch between their personality and abilities and the role they are in. This mismatch is subjective, depending on the individual as much as it is related to any particular job. So while it can mean that a person has chosen a job outside of their natural abilities, it can also mean that there may be a discrepancy in expectations between the person and the organisation. So this is not just an issue of too much work. Other central elements include control, values, community, fairness, and rewards.

To prevent or resolve some of the issues associated with burnout, people need to have a sense of control at work. They need to feel rewarded (not just financially, but also socially) and treated fairly. They need to feel that they are part of a community that communicates in a civil manner and shares the same or at least similar values. Since this job-person mismatch is a subjective experience, a positive outlook towards work also helps avoid burnout. Our research showed that people who have a better ‘match’ in one factor tend to score better in the other factors as well.

So how can burnout be addressed? Awareness is the first step towards recovery. Education is essential for people to recognise and identify burnout. Practising mindfulness can prove to be an excellent tool for anyone. By becoming more in tune with our own thoughts and emotions, evaluating them in a non-judgemental way, we can avoid falling down the slippery slope towards an unhealthy mental state.

Keeping boundaries and a correct work-life balance is another point. Having time for life outside work and being passionate about other activities is critical. Whether it’s exercise, writing, or creating art, cultivating other interests keeps our worlds varied and occupied. It creates a situation where there are other things to focus on when difficult times come.

From an organisational perspective, we need to work harder to recognise that employees are the most important resource at any workplace. They need to be supported and involved in decision making as much as possible.

Burnout is linked to other mental health conditions such as depression and anxiety. Any employee who experiences mental health problems that impinge on one’s life must feel that they are not alone and help is available. Most people spend the majority of their day and life at work so we need to make sure that it is experienced as positively as possible. 

Four reasons why we should not forget about Ebola

Author: Dr Raquel Medialdea-Carrera

Dr Raquel Medialdea-Carrera

When was the last time you heard about the Ebola virus? Many of you may recall Ebola dominating headlines in global news throughout 2014 and 2015 when it spread explosively across West Africa, claiming more than 11,300 lives.

For the last few years, Ebola has been my focus, passion, and dreaded nightmare rolled into one. In 2015, I joined a wonderful team of physicians, nurses, and scientists, that were leading the fight against Ebola in Sierra Leone. We worked in Ebola hospitals isolating patients and supporting survivors of the virus’ worst epidemic in history. Then, the World Health Organization (WHO) declared that the outbreak was over in 2016. News stations stopped covering our progress. Discussions about the disease dwindled. But the fight to eradicate Ebola was far from over. 

Since August 2018, an Ebola epidemic has spread across the Democratic Republic of Congo (DRC), affecting over 2,000 people and becoming the second largest epidemic ever recorded. Over the last few weeks, I have joined the WHO to support the fight against it in Africa.

The latest Ebola outbreak in Congo is affecting people who were already suffering from a major humanitarian crisis. People in the DRC are devastated by years of violence and conflict, resulting in the largest displacement emergency in Africa. Four and a half million are currently fleeing their homes. With over 100 different armed groups in the country, the challenge of ending this Ebola outbreak is on a whole new level. But still, there is hope.

Over the last few years, researchers have toiled hard and developed a powerful vaccine against the Ebola virus. This vaccine is still under evaluation, however, the preliminary results show a wonderful efficiency of over 97.5%. Even so, we have to remain aware. Ebola is a cruel, painful death sentence for most people who get infected, and leaves in its wake a trail of broken families, hundreds of orphans, and shattered hospitals. It decimates economies and destroys societies, leading to even more poverty and hardship. This is why we cannot forget about Ebola.  

Saving the Maltese freshwater crab from extinction

Author: Clayton Sammut

A considerable amount of endemic species inhabit the Maltese Islands. The Maltese freshwater crab (Qabru in Maltese) is one of them. In the 50s, the invertebrate was so abundant that freshwater crab soup was a common Maltese delicacy. And up until Malta adopted the Euro, it graced the Maltese five cent coin. The Maltese freshwater crab is unique to our heritage, but it is now threatened with extinction. 

Under the supervision of Dr Adriana Vella and the University of Malta’s conservation research group, I used various population and biological parameters to analyse the data and produce conservation recommendations.

To estimate the crab population size and density, I used two techniques known as the capture–recapture method and distance sampling in a number of repeated surveys in different sites throughout the dry (August to mid-September) and wet season (October to January). I then measured the crabs to determine their life stage and sex. This revealed more information about the reproductive population size and recruitment at each study site.

What we found was that there was an imbalance in the number of female to male breeding adults, which resulted in a small amount of offspring. This means the population cannot sustain itself, putting the species in grave danger.

Beyond health and numbers, we also directed attention to the crabs’ natural habitat. We wanted to find out whether hydrological and chemical parameters, such as water depth and water acidity, are also having an impact. As it happens, the freshwater crab’s population density is affected significantly by a water stream’s depth, width, velocity, and acidity (pH). We also found that specific sites and seasons also had an impact.

Direct water extraction, excessive use of fertilisers, and water stream channelisation are creating severe drought that suffocates the crabs during summer. So much so that adult male crabs were seen preying on their own juvenile crabs.

Looking at the rapid decline of watercourses around the Maltese Islands throughout the years, and the abuse that goes ignored and unchecked, the freshwater crab will not have a future unless we act immediately.

There are three things that we can do to undo some damage. We can fund research to determine if a reintroduction programme would work in sites which previously hosted the crab. We can also create new engineered habitats which can host the crab and bolster the population. Finally, the highly diverse habitats that are now hosting the crab can be turned into protected nature reserves. The nature reserves could engage citizens with Maltese organisms. If run as a social enterprise, it could generate funds to support important research. Protecting the animals that call our islands home is our duty as responsible citizens, but it goes beyond that. Protecting them means protecting our surroundings, our home, from a path that severs us from our roots. Protecting them is protecting ourselves. 

Voices for freedom and choice

Author: Dr Alexander Clayman

Dr Alexander Clayman

Abortion is a criminal offence in Malta. This means Maltese women who wish to end their pregnancy have severely limited choices. Those more affluent can pay to terminate their pregnancy abroad. Those who do not have the money can either continue the pregnancy against their will or terminate locally under unsafe conditions, risking both their health and freedom. 

Any woman who undertakes an abortion potentially faces three years in jail. Anybody who assists, such as a doctor, could also be sentenced to four years behind bars. This flies in the face of best medical practice which states that safe abortion services should be accessible to women who need them. 

A few weeks ago a group of doctors, including myself, came together to set up Doctors for Choice Malta in order to advocate for sexual and reproductive health. This includes comprehensive sex education (NOT abstinence-only education) and access to free contraception (condoms, pills, and intrauterine devices). Increased use of contraception alone results in fewer unwanted pregnancies and subsequent abortions. Putting contraceptives in the hands of comprehensively sex-educated individuals can do even more. This said, abortion still needs to be available to those people who need it. 

As a doctor, I feel I have a duty to use my knowledge and skills to better my community’s health. Together with Doctors for Choice, we are basing our efforts not on opinions or morality, but on years of medical and sociological research which shows that sex education, contraception, and accessible abortions make a society healthier. 

The irony was not lost on me when comments accusing me of being a baby-killing-mad-axe-murderer-who-doesn’t-understand-what-a-real-doctor-is started rolling in. Luckily for me, forewarned is forearmed, and the negativity failed to penetrate very deep. 

What did strike me was the contrast between the way people communicate their derision and their support. Abusive comments come in fast, prominent, and loud. Supportive comments are usually sent in private. At present, it’s clearly very easy to be openly anti-choice, but very difficult to be openly pro-choice. 

To those afraid to raise their voice and speak the truth, I say: whatever dogma, tradition, or a battalion of angry keyboard lieutenants might tell us, those who advocate for reproductive choice have nothing to be ashamed of. We are on the right side of history.

Paintings in motion

Vince Briffa’s contribution to the Venice Biennale in 2019 is OUTLAND. An audio-visual piece inspired by The Odyssey, a story intimately linked to the Maltese islands’ own folklore, the work unfurls over many layers.

On one level, it explores the lure of safety and the numbness that can bring—exhibited through Ulysses’ portrayal, who is caught in a bubble of his own making. ‘The plastic room replaces the island from the story, presenting a different interpretation,’ explains Briffa. Here, it is Ulysses’ own mind and thoughts that keep him trapped. 

The character of Calypso is also a reflection of the theme MALETH—port and safe haven. ‘She is both a lover and oppressor,’ Briffa says. ‘Calypso offers a haven for Ulysses during the seven years he spends harboured in her cave. But he is also her prisoner.’

Finally, there is fragmentation and distortion to create new from old. Penelope is Ulysses’ waiting wife, torn between longing for her husband’s safe return and an uncertainty she secretly harbours—is that even what she truly wants? Her presence in the work comes through the use of Emmanuel Mifsud’s poem Penelopi Tistenna (‘Penelope waits’). For Briffa, the Maltese language helps the story ‘take on a different life.’

The work’s duality is apparent. Images are juxtaposed against one another. One can observe two characters simultaneously, living their own truths and challenging each other. However, the conflict is not structured. ‘It’s a contemporary art piece, not film. There is no story. It’s more of a painting. I am, myself, a painter first,’ Briffa notes. 

So for those who find a narrative in this piece, know that it is uniquely yours. The question now is: will you share it?

Redesigned hip joints need a simulator

People are living longer than ever. But a long life has its price. With age come more diseases and health issues, such as hip problems that can limit a person’s mobility. 

Hip replacement procedures have become common, although implants have a lifespan too. It might happen that a hip replacement you get at 60 needs to be replaced at 75. This is not the ideal scenario.

To minimise these cases, researchers are testing new materials and designs to prolong prostheses’ lifespans. These potential solutions need to be tested, but each test costs tens of thousands of euro. Enter, the University of Malta’s hip joint simulator.

Hip joint simulator in all its glory.

The hip joint simulator is a machine that replicates the joint movements and loads imposed on the human hip. To do so, the simulator uses three stainless steel frames, each of which can be controlled independently using motors. These motors act as the ‘muscles’ of the hip, programmed to replicate the walking cycle during testing.

When it comes to simulating load and forces, a mechanism can load the implants with weights of up to 300kg in a fraction of a second. This emulates what happens while walking, when the weight of the body rests on one leg due to the body’s shift in the centre of gravity. While running, inertial forces can cause the hip to sometimes take five times a person’s body weight.

Finally, to simulate the environment inside the human body, researchers use a specialised solution that mimics the bodily fluids surrounding the hip joint. They even warm the fluid to imitate body temperature. 

The hip joint simulator forms part of the MaltaHip project that intends to radically redesign hip implants to give them the longer lifespan patients want and need. Watch this space for more.  

The MALTAHIP project is funded by the Malta Council for Science and Technology through FUSION: The R&I Technology Development Programme 2016 (R&I-2015-023T).
