However, the environmental pollutants in the fish have the opposite effect and appears to eliminate the protective effect from fatty fish intake. This has been shown by researchers at Chalmers University of Technology in Sweden, using innovative methods that could be used to address several questions about food and health in future studies.</b></p>​Research on the effect of fish consumption on diabetes risk has produced contradictory results in recent years. Some studies show that eating a lot of fish reduces the risk of developing type 2 diabetes, while others show it has no effect, and some studies show it even tends to increase the risk. Researchers at Chalmers University of Technology conducted a study with an entirely new design and have now arrived at a possible explanation for this puzzle.<br /><br />“We managed to separate the effect of the fish per se on diabetes risk from the effect of various environmental pollutants that are present in fish,” says Lin Shi, a Postdoc in Food and Nutrition science. “Our study showed that fish consumption as a whole has no effect on diabetes risk. We then screened out the effect of environmental pollutants using a new data analysis method based on machine learning. We were then able to see that fish themselves provide clear protection against type 2 diabetes.”<br /><br />“Protection is provided primarily by consumption of fatty fish. However, at the same time, we saw a link between high consumption of fatty fish and high contents of environmental pollutants in the blood.”<br /><br />Environmental pollutants measured in the present study are persistent organic pollutants (POPs), for example dioxins, DDT and PCB. Previous research has shown that they may be linked to increased risk of type 2 diabetes. The varying effect of fish on diabetes risk in different studies could therefore be due to varying levels of consumption of fish from polluted areas in the different studies.<br /><br />According to the Swedish National Food Agency, food is the main source of exposure to dioxins and PCBs. These substances are fat soluble and are primarily found in fatty animal foods such as fish, meat and dairy products. Particularly high contents are found in fatty fish such as herring and wild salmon from polluted areas. In Sweden, for example, this means the Baltic Sea, the Gulf of Bothnia and the biggest lakes, Vänern and Vättern.<br /><br />The Chalmers researchers also used a new method to find out what the study participants had eaten, as a complement to questionnaires on dietary habits. Previous research has often relied entirely on questionnaires. This produces sources of error that may also have contributed to the contradictory results concerning fish and type 2 diabetes.<br /><br />“Using a technique known as mass spectrometry based metabolomics, we identified around 30 biomarkers in blood samples, i.e. specific molecules that could be used to objectively measure of how much fish the study participants had consumed,” says Lin Shi.<br /><br />Overall, the new methodology provides considerably better tools for this research field. They can be used to better discern which dietary factors are the actual causes of different types of health effects.<br /><br />“Metabolomics and the new way of analysing data give us new opportunities to distinguish between effects from different exposures that are correlated,” says Rikard Landberg, Professor of Food and Nutrition Science at Chalmers. “This is very important as otherwise it is difficult to determine whether it is diet, environmental pollutants or both that affect the risks of disease.”<br /><br /><strong>More about the study<br /></strong><br />The study is a case-control study nested in a prospective cohort in Västerbotten in northern Sweden. The participants had completed questionnaires on dietary habits and lifestyle, and provided blood samples, which were frozen. A total of 421 people who had developed type 2 diabetes after an average of 7 years were included, and they were compared with 421 healthy control individuals. The original blood samples were then analysed. In addition, blood samples were analysed that had been provided ten years after the first blood samples by 149 of the case-control pairs.<br /><br /><div>The study is reported in the article <a href=""><em>Joint analysis of metabolite markers of fish intake and persistent organic pollutants in relation to type 2 diabetes risk in Swedish adults</em></a>, which was published in <em>The Journal of Nutrition</em>. In addition to the Chalmers researchers, researchers from Umeå University, Karolinska Institutet, the National Institute for Health and Welfare in Finland and the University of Eastern Finland also participated.</div> <div><br /></div> <div>Text: Johanna Wilde<br /></div> Wed, 19 Jun 2019 07:00:00 +0200 fumes of concern are sent below the surface<p><b>Shipping companies are now installing scrubbers on a large number of vessels around the world to meet the more stringent rules on sulfur emissions that come into effect at the turn of the year. Researchers in Gothenburg say that this method runs the risk of only transferring the environmental pollution from the air to the sea. They warn that the effects in the marine ecosystem could be serious.</b></p>​In January 2020, the limit is lowered drastically for how much sulfur global shipping can release into the air. The international maritime organization IMO has tightened the rules from a maximum of 3.5 to 0.5 per cent permitted sulfur content in the fuel. Many shipping companies now choose to install scrubbers on their vessels, instead of switching to much more expensive low sulfur bunker oil or alternative fuels. A scrubber washes the exhaust gases in a fine spray of water, which can lower the sulfur content in the air emissions to the corresponding lower level. <div><br /></div> <div>Ida-Maja Hassellöv, associate professor of marine environmental science at Chalmers, is deeply concerned about the development. Not because the sulfur is moved from the air to the sea – it is converted into it sulphate which is a natural element of seawater – but because of the consequences of discharging scrubbing water into the sea has. </div> <div><br /></div> <div>​&quot;One reason for the stricter rules is to reduce acidifying emissions sulfur oxides from ships&quot;, she says. &quot;But scrubber use does not reduce emissions, it only concentrates it in the sea instead of spreading in the air over larger surfaces of the sea, land and lakes. When the sulfur oxides react with water and forms sulphate, it becomes heavy local acidification of the sea water.&quot;</div> <div><br /></div> <div>&quot;In addition, a number of other contaminants are washed from the exhaust, which causes scrubbing water to contain a cocktail of toxic substances. For example, we have shown that a ship can release as much copper and zinc from its scrubber as it does from its bottom paint. During certain conditions nitrogen oxides from the exhaust gases can also be washed out. For example in the Baltic Sea, this can contribute to the eutrophication problem.&quot;</div> <div><br /></div> <div>So-called open scrubs are an obvious problem because they release all scrubbing water into the sea. But even most closed scrubbers, that circulate the water and add alkaline chemicals, separates some scrubbing water and releases it. They need to do this to be able to replenish with new water and alkaline chemicals. It releases smaller volumes of scrubbing water than open scrubs, but that water, on the other hand, has a higher concentration of pollutants. </div> <div><br /></div> <div>Ida-Maja Hassellöv is part of a research group at Chalmers examining how scrubbing water affects plankton, in collaboration with professor Angela Wulff's research group at Gothenburg university. They are the first researchers to do field trials on natural plankton communities. Large bags of seawater from the Stockholm archipelago is treated with scrubber water, and in parallel, the researchers do laboratory tests on individual plankton species. The results show, among other things, different Plankton species are differently sensitive to scrubbing water. It is not surprising in itself but indicates the difficulty of making complete, detailed analyses of large-scale effects of scrubber use. One particular challenge is to distinguish the effects of acidification and toxic substances when the algae are simultaneously fertilized form of nitrogen oxides.</div> <div><br /></div> <div>&quot;Nobody knows what the scrubbing water would mean on a larger scale and on a longer term&quot;, says Ida-Maja Hassellöv. &quot;But because plankton is the basis of the entire marine ecosystem it is very scary that the number of scrubbers right now increases exponentially. Particularly when it comes to the Baltic Sea, which is already heavily burdened by environmental degradation, but this also applies to many other seas. The situation is most strained in the areas that have the most important biological productivity – that is, close to the coasts.&quot; </div> <div><br /></div> <div>Uncertainty is not only considerable when it comes to the effect of the emissions on the marine ecosystem, but also in terms of the content of different types of scrubbing water. Few independent studies have been done. An example of the lack of knowledge is that no one even knows where the metals in the scrubbing water come from. From the fuel, lubricating oils or pipelines, are some of the guesses. And the metals are an immense risk, especially in combination with acidification. A low pH causes metals to turn into free ion form, which makes them more toxic. </div> <div><br /></div> <div>The full picture is rarely discussed when it comes to scrubbing emissions, according to Ida-Maja Hassellöv. </div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">&quot;Often people just talk about the sulfur itself, but that is not the real problem. As a result, scrubbers appear like a good and inexpensive way to meet the new sulfur rules. A scrubber pays off in just about 18 months compared to buying low-sulfur bunker oil.&quot;</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">So the need is great for more of the type of research that Ida-Maja Hassellöv is engaged in together with her colleagues Erik Ytreberg and Amanda Nylund. But in view of the scrubber boom, which is going on right now, she believes that the need for faster measures is even greater. </span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">&quot;In the case of Sweden, the Swedish Transport Administration should prohibit open scrubbers in Swedish waters. China, California and some European ports have introduced such bans, and we already have enough research to justify it to Sweden. If there is a time to use the precautionary principle, it is now.&quot;</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">From <em><a href="/sv/nyheter/magasin/Sidor/default.aspx">Chalmers magasin nr 1 2019​</a></em><br /></span></div> <span></span><div><div><div><span></span></div></div></div>Tue, 18 Jun 2019 00:00:00 +0200 power research advances the energy transition<p><b>​Since 2010, the Swedish Wind Power Technology Centre has gathered and developed knowledge in collaboration with industry, and now constitutes a national knowledge industry for wind power technology. The research centre recently entered into its third stage, now going towards larger projects in collaboration with multiple disciplines. Several of the research results have attracted interest outside Sweden, and the centre is now becoming a player on the international arena.</b></p><p>​Today, wind power is the energy source with the greatest potential in the transition towards green energy in Sweden. A national political goal dictates that all electricity production should come from 100 percent renewables by 2040. From today's 11 percent, wind power is estimated to make up at least 40 percent of the Swedish electricity production within a couple of decades, probably more. The Swedish Wind Power Technology Centre (SWPTC) unites theory and practice in a close collaboration between industry and academia. The common goal is to optimise the capacity of wind turbines and make production and operation more cost-effective.</p> <h2 class="chalmersElement-H2">New methods for lowering costs and prolonging life-span</h2> <p>Unforeseen down-time in production can incur high costs for wind power owners, not only because of faulty components that need replacing, but also because of reduced revenue due to no energy production.</p> <p><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Vindkraftsforskning%20rustar%20branschen%20för%20snabbare%20energiomställning/Sara_Fogelstrom_250x350px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:175px;height:245px" />“In the transition towards 100 percent renewable energy in Sweden, it is important that we can take care of our wind turbines, as they will count for a large part of the electricity supply in the future. An important contribution from SWPTC in promoting the wind energy expansion is to develop better maintenance methods and knowledge about prolonging the life-time of wind turbines”, says Sara Fogelström, who is the coordinator of the research centre.</p> <p>With data from the wind turbine, one can calculate the expected life-span of different components and, on that basis, provide an optimal maintenance schedule. It also means that you can schedule the maintenance to a time when there is little wind, when the wind turbine would have a low production anyway.</p> <p>“The methods developed within SWPTC advocate a so-called opportunistic maintenance, which means that the system proposes replacing of several components at once, as the service technician is on site. Problems can then be addressed before they become too costly and, also, you do not have to go out to the windfarm as often, Sara adds.</p> <h2 class="chalmersElement-H2">Several research disciplines in collaboration</h2> <p>Until now, the centre has been building up fundamental knowledge, through individual research projects, within each of the research disciplines needed to understand how a wind turbine works. For example, at Chalmers, researchers in fluid dynamics are looking at how wind turbines in the forests are affected by the surrounding terrain. Researchers in dynamics investigate how the mechanical drive train, and in particular the gearbox, works. In electric power engineering, research is being carried out on detection of electric faults in the generator and how windfarms can be better connected at sea. Furthermore, researchers in construction engineering are interested in how different loads (“forces”) affect the foundation of the wind power turbine. Mathematicians are also involved in calculating how to optimise the maintenance methods.</p> <p>One of the projects that endorses the entire spectrum of competences is a project about how individual wind turbines are affected under harsh operating conditions. In complex terrain, it is subjected to ever-changing winds, which results in greater mechanical stress on the gearbox than it would in flat terrain. This explains why maintenance costs are often much higher in Sweden, which has a hillier terrain, than Denmark, which is mostly flat. <img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Vindkraftsforskning%20rustar%20branschen%20för%20snabbare%20energiomställning/Vindfält_710x330px.jpg" alt="" style="margin:5px" /><br /><em>With a new calculation model, researchers can see exactly how the wind field of each individual wind turbine behaves in a wind farm.

Ola Carlson is a Professor at the Division of Electrical Power Engineering and the Director of SWPTC. He is leading the project, which is carried out in collaboration with several industrial partners.</p> <p>“We have developed a calculation model that takes many different parameters into account, which can calculate the accumulated load that an individual wind turbine is subjected to. This knowledge is needed for manufacturers to be able to adapt the design of wind turbines to different operating conditions”, says Ola.</p> <h2 class="chalmersElement-H2">An international player</h2> <p>The research results have received attention also outside Sweden. The centre is now participating in several international networks and organisations, such as the European Energy Research Alliance, the European Academy of Wind Energy and the international energy agency IEA.</p> <p>“It is an important strategic move. We have already received inquiries of collaboration in major EU projects. Besides being a collaborative platform, it is also a way of spotting trends in the field”, Sara concludes.</p> <h3 class="chalmersElement-H3">About Swedish Wind Power Technology Center (SWPTC)</h3> <p>The centre was established in 2010 and during the first two stages, 35 research projects were carried out in collaboration with 26 industrial partners and research institutes. Prior to the start of stage 3 in January 2019, the research had generated 38 published articles and eight doctoral theses.

Measuring it can be a challenge, however, as the equipment tends to be large and expensive. But soon, this may change, thanks to a small, optical nano-sensor, developed at Chalmers, which can be mounted onto an ordinary streetlight.​</b></p><div>​The technology is already in use in western Sweden, and researchers and other interested parties hope that the sensor could soon be used in many broad contexts. A collaboration with the University of Sheffield is also underway. <br /><span style="background-color:initial"><img src="/SiteCollectionImages/Institutioner/F/350x305/350x305_IremTanyeli_labb_20190405.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" />“Air pollution is a global health problem. To be able to contribute to increased knowledge and a better environment feels great. With the help of these small, portable sensors, it can become both simpler and cheaper to measure dangerous emissions extremely accurately,” says Chalmers researcher Irem Tanyeli, who has helped develop the small sensors, which measure nitrogen dioxide with great precision. <br /><br /></span></div> <div>For the hi-tech sensors to make the move from the lab out into the real world, Irem Tanyeli worked with the Gothenburg-based company Insplorion, co-founded by Chalmers researcher Christoph Langhammer in 2010. With help from financier Mistra Innovation, he has been involved with the company’s efforts at taking on the great environmental challenge of precisely mapping air pollution. <br /><br /></div> <div><img src="/SiteCollectionImages/Institutioner/F/350x305/ChristophLanghammerfarg350x305.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:250px;height:218px" />“This is a great example of how a university and a company can collaborate. Both parties contribute with their expertise to create a new product, contributing to a more sustainable society,” says Christoph Langhammer, Professor at the Chalmers Department of Physics.<br /><br /></div> <div>Exhaust gases from road traffic are responsible for the majority of nitrogen dioxide pollution in the air. Breathing in nitrogen dioxide is harmful to our health, even at very low levels, and can damage our respiratory systems and lead to cardiac and vascular diseases. According to the World Health Organisation, air pollution is the single biggest environmental health risk worldwide. <br /><br /></div> <div>The new optical nano-sensor can detect low concentrations of nitrogen dioxide very precisely – down to the parts-per-billion level (ppb). The measuring technique is built upon an optical phenomenon which is called a plasmon. It arises when metal nanoparticles are illuminated and absorb light of certain wavelengths. Christoph Langhammer and his research group have been working in this area for over a decade, and now innovations are starting to see the light of day. <br /></div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/F/350x305/350x305Leading%20Light%20armatur.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />For the last two years, Irem Tanyeli has been working with optimising the sensor material and conducting tests under differently simulated environmental conditions.

It has led all the way to summer jobs and awards.</b></p>​<span style="background-color:initial">During spring, small air quality measuring stations have been placed on several bus stops along the route of bus 55, including at Chalmersplatsen and Götaplatsen. In addition, one of the buses on the line has had a sensor on the roof, which in real time could measure the air quality of the city along the way the bus travels.</span><div>“There are already great sensors from the City’s Environmental Administration, but with a bus you can cover a huge area. In addition, the measuring equipment ends up in a good height, it is at street level that people breathe”, says Lina Lagerquist who, together with Magnus Carlsson, Åke Axeland, Henrik Hagfeldt, Simon Duchén and Sofija Zdjelar, study the third year at Computer Technology and have been part of the group.</div> <div><br /></div> <div><strong>Placed a meter on the bus</strong></div> <div>The idea appeared on an <a href="/sv/styrkeomraden/energi/nyheter/Sidor/Moved-vinnare-i-Ideathon.aspx">ideathon</a> before Christmas. After winning it, the students went on to do a bachelor thesis based on the idea.</div> <div>“We wanted to design a chain between sensors that measure air quality in Gothenburg and a web application where we can both see the measurement data in real time and during time periods in compiled reports. The chain also includes a server that we have developed that receives and manages the measurement data”, says Lina Lagerquist.</div> <div><br /></div> <div>Early during the bachelor thesis, contact was made with Ericsson, Västtrafik and the Environmental Administration, and then there was no difficulty in placing a meter on one of the electric buses that go through town.</div> <div>“Everyone has been accommodating and it went quickly to be permitted to place the sensors out when we got in touch. That's a topical issue”, says Lina Lagerquist.</div> <div><br /></div> <div><strong>Important collaboration for Västtrafik</strong></div> <div>Hanna Björk is Head of Sustainability at Västtrafik:</div> <div>“Our collaboration with Chalmers and the students is important for us, to be able to take part of the ideas and knowledge that the students have. We have recently conducted a test drive campaign to attract motorists to more sustainable ways of traveling, with the issue of whether we should act differently if we saw the problem – that is, the poor air quality. Carrying out this test gives another dimension to the problem and hopefully the students' ideas can be taken from test to development that society then benefits from”, she says.</div> <div><br /></div> <div>The project has used the Environmental Administration's air quality meter on Nordstan's roof as a reference. It turned out that the project's simple and inexpensive sensors followed the same trends but were not sufficiently reliable for the students to want to go out with their results.</div> <div>“We deliberately chose cheap sensors to see how they managed. Now we are thinking about how to make progress, for example placing more of them and denser, to get a more reliable result”, says Lina Lagerquist.</div> <div><br /></div> <div><strong>Summer jobs at Ericsson</strong></div> <div>And there will opportunities for more tests and theories. Everyone in the group have gotten a summer job at Ericsson.</div> <div>“We will work on developing a foundation for a technical system that <a href="">ElectriCity </a>will be able to use in future air measurements. It is such a great opportunity that we are very happy about. And it is awesome to see that you can put your studies into practice, that we can accomplish something and are on the right path”.</div> <div>In addition, the group has been awarded the Entrepreneurial Student Award within the Eng project at Chalmers.</div> <div><br /></div> <div>In the end, Lina Lagerquist and the others hope to be able to contribute to making people more aware of the problems of air pollution.</div> <div>“Poor air quality is a global problem, and one has to understand what it is to do something about it. Therefore, we hope that this project will be the same eye-opener for others as it has been for us”.</div> <div><br /></div> <div><strong>Text:</strong> Erik Krång</div> <div><strong>Photo:</strong> Johan Bodell</div> Wed, 12 Jun 2019 00:00:00 +0200 box that opens new doors into the nanoworld<p><b>Researchers at Chalmers have discovered a completely new way of capturing, amplifying and linking light to matter at the nanolevel. Using a tiny box, built from stacked atomically thin material, they have succeeded in creating a type of feedback loop in which light and matter become one. The discovery, which was recently published in Nature Nanotechnology, opens up new possibilities in the world of nanophotonics.</b></p><div><span style="background-color:initial"><div><span style="background-color:initial">Photonics is concerned with various means of using light. Fibre-optic communication is an example of photonics, as is the technology behind photodetectors and solar cells. When the photonic components are so small that they are measured in nanometres, this is called nanophotonics. In order to push the boundaries of what is possible in this tiny format, progress in fundamental research is crucial. The innovative ‘light box’ of the Chalmers researchers makes the alternations between light and matter take place so rapidly that it is no longer possible to distinguish between the two states. Light and matter become one. </span><br /></div> <div><span style="background-color:initial"><br /></span></div></span><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/RuggeroVerre_200px.jpg" class="chalmersPosition-FloatRight" alt="" /><span style="background-color:initial"></span><span style="background-color:initial"><div>“We have created a hybrid consisting of equal parts of light and matter. The concept opens completely new doors in both fundamental research and applied nanophotonics and there is a great deal of scientific interest in this,” says Ruggero Verre, a researcher in the Department of Physics at Chalmers and one of the authors of the scientific article.</div> <div><br /></div> <div>The discovery came about when Verre and his departmental colleagues Timur Shegai, Denis Baranov, Battulga Munkhbat and Mikael Käll combined two different concepts in an innovative way. Mikael Käll’s research team is working on what are known as nanoantennas, which can capture and amplify light in the most efficient way. Timur Shegai’s team is conducting research into a certain type of atomically thin two-dimensional material known as TMDC material, which resembles graphene. It was by combining the antenna concept with stacked two-dimensional material that the new possibilities were created. </div> <div><br /></div> <div>The researchers used a well-known TMDC material – tungsten disulphide – but in a new way. By creating a tiny resonance box – much like the sound box on a guitar – they were able to make the light and matter interact inside it. The resonance box ensures that the light is captured and bounces round in a certain ‘tone’ inside the material, thus ensuring that the light energy can be efficiently transferred to the electrons of the TMDC material and back again. It could be said that the light energy oscillates between the two states – light waves and matter – while it is captured and amplified inside the box. The researchers have succeeded in combining light and matter extremely efficiently in a single particle with a diameter of a mere 100 nanometres, or 0.00001 centimetres. </div> <div><br /></div></span><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/TimurShegai_190510.jpg300x.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px;height:355px;width:280px" /><span style="background-color:initial"><div>This all-in-one solution is an unexpected advance in fundamental research, but can hopefully also contribute to more compact and cost-effective solutions in applied photonics. </div> <div>“We have succeeded in demonstrating that stacked atomically thin materials can be nanostructured into tiny optical resonators, which is of great interest for photonics applications.

Sometimes, where we’re trying to improve the situation, we have ideas which seem good but which don’t really focus on the major problems. However, in this case I think we’re spot-on”, says Ulf Svanberg, Professor of Food and Nutrition Science at Chalmers.</span><br /></div> <div><span><br /></span> </div> <div><div><strong>The initiative was launched </strong>by President and CEO of Chalmers, Stefan Bengtsson, to bring about greater collaboration with Universities in East Africa. Keeping in mind the UN’s 17 Sustainable Development Goals - aimed at combating extreme poverty, reducing inequality and injustice in the world, promoting peace and justice and solving the climate crisis - Chalmers has identified three focus areas: food, water and energy. The partnership has been formed around Chalmers researchers from these fields.</div> <div>In early April, researchers from Chalmers and the Jaramogi Oginga Odinga University of Science and Technology, JOOUST met for a workshop in the Kenyan port of Kisumu, on the northern shores of Lake Victoria.</div></div> <div> </div> <div><strong><img class="chalmersPosition-FloatRight" alt="Monica Awuor Ayieko, photo by Maria Grahn" src="/sv/styrkeomraden/energi/nyheter/PublishingImages/Monica_A_JOOUSTIMG_7194-(002).jpg" style="margin:5px" />Before travelling, the researchers</strong> had sent descriptions of their specialist fields. But when Svanberg tried to find a potential partner with a background in food, he found that there really weren’t any.</div> <div>Then, along came Monica Awuor Ayieko, heading a research group whose focus included the nutritional value of insects, at the Africa Center of Excellence in Sustainable Use of Insects as Food and Feeds, INSEFOODS.</div> <div>“I had no expertise in that area, so I read a comprehensive research article from the Netherlands. Insects are eaten in Africa and Asia and I immediately saw the connection between Monica’s research and my own”.<br /><br /></div> <div>Svanberg has a well-established background in food and nutrition science. In the early 1980s, his first doctoral student was Alex Mosha in Tanzania, who worked at the country’s Food and Nutrition Centre. They travelled around, weighing and measuring children in rural areas to investigate the prevalence of malnutrition and anaemia.</div> <div>Iron deficiency anaemia and malnutrition are global health problems entailing diminished quality-of-life and increased risk of death from infectious diseases like measles and malaria. Currently, over half of preschool children in Africa are affected by iron deficiency anaemia.</div> <div><br /> </div> <div><strong>Svanberg and his doctoral student discovered Power Flour. </strong>This sprouted flour could transform the thick porridge the children were eating into a nutritious gruel and help reduce the number of malnourished children in the region. </div> <div>“Without enough protein, children will be of shorter stature relative to their age. There is research showing the societal effect of this, including lower GDP in countries where the population is iron-deficient,” explains Svanberg, pointing out that food and nutrition are at the centre of the UN’s global goals.</div> <div>“That’s how I got involved. I’ve also run research projects in a number of other countries such as Ethiopian, Uganda and Mozambique. But, up to now, Kenya was one of the few East African countries where I didn’t have a partnership.” </div> <div><br /></div> <div><strong>So, how do insects help? </strong><span>Iron from animal foods is easily absorbed by the body but the iron present in cereals such as rice and maize is much less absorbed.</span></div> <div>“This is the cunning part. If you add a little bit of meat with the cereals, more of the iron from the cereals is absorbed. Mixing insects into cereal foods may therefore have a   positive effect on iron uptake”, says Svanberg.</div> <div> </div> <div>At the Kisumu workshop, the researchers brought together a research project which they called “Hidden treasures of underutilised plants and insects: from molecule to landscape”.</div> <div>Svanberg explains that they set out to study and map insects and “forgotten” plants; nutrient-rich green leaves used in rural villages for purposes unknown to us. Researchers will also study land use in cultivation. Food wastage is a problem in Kenya, with some 30 percent of perishable foods in the cities going to waste.</div> <div><br /> </div> <div><img class="chalmersPosition-FloatLeft" alt="Cakes with a base of insects, photo by Maria Grahn" src="/sv/styrkeomraden/energi/nyheter/PublishingImages/Kenya_kakor.jpg" style="margin:5px" /><strong>“So, there’s a lot to do in this project. </strong>This is a new university, but the researchers we met are incredibly talented. They have a drive and a positive attitude to research collaboration. We’ve already appointed a tentative doctoral student for our project and a partnership within the other fields is also underway.</div> <div><br /></div> <div>Svanberg received a pack of biscuits from JOOUST, to which Monica had added 10 percent insects.</div> <div>“It tastes pretty much like shortbread but with a slightly bitter aftertaste. In June, when we discuss this partnership with the department, I’m going to hand those biscuits around at coffeetime!”</div> <div> </div> <div><strong>Just as the interview is ending</strong>, Svanberg mentions a quote from then US president, John F. Kennedy, at the first World Food Congress, held in Washington on June 4,1963:</div> <div>“We have the ability, as members of the human race, we have the means, we have the capacity to eliminate hunger from the face of the earth in our lifetime. We only need the will”.</div> <div>“President Kennedy was right. He understood and had the vision. It’s 40 years since I first came to Africa but now we’re finally here to realise the UN’s Sustainable Development Goals; to eliminate hunger and malnourishment by 2030.<br /><br /></div> <div>Maria Grahn is the photographer for all photos.

There are several unanswered questions about autonomous vehicles. The EU is, therefore, investing EUR 4 million in research within this research field. Chalmers has been entrusted with the task of coordinating the Marie Curie project.</b></p>​The researcher who has been entrusted with the task is Jonas Bärgman who works at the Department of Mechanics and Maritime Sciences and the Division of Vehicle Safety. The Marie Curie project has the title SHAPE-IT, Supporting the interaction of Humans and Automated vehicles: Preparing for the Environment of Tomorrow. It runs for four years and will fund 15 doctoral students, spread over six universities across the EU. The overall goal of the project is to enable rapid and reliable development of safe and user-centred automated vehicles for urban environments. <div><br /></div> <div>”In the project, we will conduct research with the goal to understand the interaction between humans and automated vehicles, how to best develop and design human-machine interfaces for automated vehicles, and how to evaluate the traffic safety effect of automated vehicles” says Jonas Bärgman. </div> <div><br /></div> <div>For each of these areas, two different aspects will be addressed: the interaction between humans and automated vehicles inside and outside automated vehicles, respectively. In addition to the coordination and project management, Chalmers will, and more specifically, the unit Crash Analysis and Prevention at the division of Vehicle Safety, have two PhD students. </div> <div><br /></div> <div>“One of the PhD-students will focus on quantitative modelling of the interaction between bicyclist and automated vehicles. The other PhD student will continue the research to develop and validate methods for assessment of traffic safety benefits of automated vehicles through virtual simulations of different scenarios” </div> <div><br /></div> <div>The Department of Computer Science and Engineering, which is a department shared between Chalmers and the University of Gothenburg, will also participate in the project with two doctoral students who, among other things, will do research on artificial intelligence (AI) linked to self-driving vehicles. This includes using AI- methods to provide a better understanding of the interaction between humans and automated vehicles, and about developing methods to integrate knowledge from the research domain of Human Factors Engineering and driver behaviour, into frameworks that are used to develop AI-based automated vehicles. </div> <div><br /></div> <div>Jonas Bärgman thinks that they will be able to address many of the questions that today there are no answers to with respect to automated vehicles and how they will/should interact with humans in city/urban environment – both from a designer perspective and from a traffic safety perspective. </div> <div><br /></div> <div>”My hopes are that we will be able to make automated vehicles much safer, while we improve the usability and acceptance for them, and, in general, build competencies around human behaviour inside and outside automated vehicles.&quot;</div> <div><div> </div></div> <h3 class="chalmersElement-H3">Read more</h3> <div><a href="/en/departments/m2/research/vehiclesafety">The Division of Vehicle Safety​​</a></div>Wed, 29 May 2019 14:00:00 +0200 the Win win award for stopping food waste<p><b>​The 2019 Win win Prize is awarded to French judge Arash Derambarsh, who managed to ban French grocery stores and restaurants from throwing away food.

The breakthrough could lead to more compact, cheaper equipment that could be useful for many applications, including proton therapy.​​​</b></p><div><p class="chalmersElement-P">Proton therapy involves firing a beam of accelerated protons at cancerous tumours, killing them through irradiation. But the equipment needed is so large and expensive that it only exists in a few locations worldwide. ​</p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P">Modern high-powered lasers offer the potential to reduce the equipment’s size and cost, since they can accelerate particles over a much shorter distance than traditional accelerators – reducing the distance required from kilometres to metres. The problem is, despite efforts from researchers around the world, laser generated proton beams are currently not energetic enough. But now, the Swedish researchers present a new method which yields a doubling of the energy – a major leap forward. </p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <div><p class="chalmersElement-P">The standard approach involves firing a laser pulse at a thin metallic foil, with the interaction resulting in a beam of highly charged protons. The new method involves instead first splitting the laser into two less intense pulses, before firing both at the foil from two different angles simultaneously. When the two pulses collide on the foil, the resultant electromagnetic fields heat the foil extremely efficiently. The technique results in higher energy protons whilst using the same initial laser energy as the standard approach.<span style="background-color:initial;color:rgb(51, 51, 51)"> </span></p></div> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"> <img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/JulienFerri_190508_200x300.jpg" class="chalmersPosition-FloatLeft" alt="" style="width:180px;height:270px" /> </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">“This has worked even better than we dared hope. The aim is to reach the energy levels that are actually used in proton therapy today. In the future it might then be possible to build more compact equipment, just a tenth of the current size, so that a normal hospital could be able to offer their patients proton therapy,” says Julien Ferri, a researcher at the Department of Physics at Chalmers, and one of the scientists behind the discovery. <br /></p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">The unique advantage of proton therapy is its precision in targeting cancer cells, killing them without injuring healthy cells or organs close by. The method is therefore crucial for treating deep-seated tumours, located in the brain or spine, for example.

One of my ambitions is to help more people get access to proton therapy.

They can be used to investigate and analyse different materials, and to make radioactive material less harmful. They are also important for the space industry. Energetic protons constitute a large part of cosmic radiation, which damages satellites and other space equipment. Producing energetic protons in the lab allows researchers to study how such damage occurs, and to develop new materials which can better withstand the stresses of space travel. </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">Together with research colleague Evangelos Siminos at the University of Gothenburg, Chalmers researchers Julian Ferri and Tünde Fülöp used numerical simulations to show the feasibility of the method.
