No. 80 PLAYING WITH TIME THE POLISH SCIENCE VOICE FROM THE PUBLISHER A revolutionary new bridge made of special composite materials is being built at Błażowa near the southeastern city of Rzeszów in a project co-financed by the National Center for Research and Development (NCBR) using European Union funds. In two years this hi-tech bridge will replace the existing steeland-wood structure, which is in poor condition, and will be the first such bridge in Poland and one of a few facilities of its kind in Europe. The new bridge will be lighter and more durable than traditional bridges. It will be made from carbon and fiberglass materials embedded in a polymer resin matrix. Such materials are used in aviation. For example, the Boeing Dreamliner range of airlines is built from composites. The project is being carried out by a consortium led by the Mostostal Warszawa company with the participation of the Rzeszów University of Technology and the Warsaw University of Technology as well as the Promost Consulting company from Rzeszów. In another innovative project, Polish information technology professionals are working to develop a breakthrough method for eliminating errors from computer software. The project is called Time Machine because it aims to enable software engineers to go back in time in a sense and find the source of errors right where they emerged. If you have ever worked at a computer you are probably familiar with the frustrating feeling when a program crashes and the results of your work are destroyed. Such occurrences are often the result of software errors. Companies that create computer soft- ware not only employ staff tasked with writing new applications but also whole teams of people whose job is to diagnose and repair errors. Kamil Kupcewicz, manager of the software development department at IT company TKomp and head of the Time Machine project—which is co-financed by the National Center for Research and Development under its Innotech program— says removing errors from computer programs takes time and money and involves many people with specialist skills. A method to deal with errors by nipping them in the bud could make things much cheaper and faster. It seems no one in the world has taken this route before and it must be a real pleasure to be a trailblazer, especially as success could include handsome financial rewards.

What is the Time Machine project? It is an innovative idea to facilitate and improve the work of programmers, particularly in terms of spotting and fixing problems. Let me give you an example. Anyone who has ever worked at a computer is familiar with the nasty experience of a program crashing and your work being lost. Such frustrating events are the result of software errors. These stem from errors that are present in every programming product. Therefore companies that create them not only have staff tasked with writing new applications but also whole teams of people whose job is to diagnose and repair errors. Computer programs have millions of lines of code describing the operations that a processor should perform. Sometimes for a simple result on the screen you have to write hundreds of lines of program code. This leads to a situation in which the diagnosis of a problem is difficult and time consuming. And fixing it is even more difficult. At the moment, to diagnose a software 3 SPECIAL GUEST F A C T F I L E KAMIL KUPCEWICZ has been managing software development projects, including R&D, for nine years. He began his career as a software developer and then became a team leader. He is currently head of the software development department at the TKomp company and manages the Time Machine project. TKomp, founded in 1996, is based in the northcentral Polish city of Bydgoszcz. The company designs, produces and implements software for managing information flow in businesses. TKomp has carried out IT projects for some of the largest companies in Poland, including PGE, KGHM Polska Miedź, PKN Orlen and PZU. 4 error it is necessary to run the program repeatedly in special conditions. So how can the Time Machine project help? We want programmers to be able to find the source of an error at its first occurrence—in a sense to enable them to go back in time and find the actual place where it emerged. Plus we want to give them an opportunity to introduce changes to the program and determine whether the error has been fixed without rebooting and entering data. Often this takes much longer than correcting a single line of code. This can be compared to an airplane flight and black box recording when something bad happens. Thanks to our Time Machine we can go back to a second prior to or to the very moment of failure and diagnose the cause of the problem based on all the flight parameters. And, most importantly, it is possible to carry out repairs in the course of the flight and safely continue with the program. SPECIAL GUEST We want programmers to be able to find the source of an error at its first occurrence—in a sense to enable them to go back in time and find the actual place where it emerged. Do you think a small company like yours will be able to revolutionize the work of programmers worldwide? We have been creating software since 1996. We are pioneers in the field of electronic support for quality management systems. That’s what we started out with. Then we created a platform for the comprehensive management of information flow in businesses—NND Integrum. Our applications are used by more than 200 Polish and international organizations. In Poland alone, this currently means about 230,000 users for our main product. From the very beginning we’ve been creating original solutions. Innovation is part and parcel of the company’s strategy. The experience in developing and testing software we have collected over the years provides a strong basis for the creation of tools such as the Time Machine. Dealing with this is a team of eight programming enthusiasts who think outside the box. How did the idea for the Time Machine come about? Every now and again we hold brainstorming sessions at our company that are expected to result in the development of the applications we create. At one such session we pondered ways of how to more accurately measure the performance of one of our solutions. My colleague Adam Kruszewski came up with an idea that was completely unrelated to that. He proposed the Time Machine concept. We started to analyze this issue and it turned out that we knew how to approach this topic. To our surprise, we learned that no one in the world had done this before. Then, in collaboration with consultants from PwC, we examined the market potential and looked for opportunities to finance our research. Your concept was a good fit for the NCBR’s Innotech program... The project involves co-financing from our own resources and from the NCBR. We are sharing the cost of the project, which comes to over zl.2.5 million. The National Center for Research Development has allocated zl.1,457,000, and we are contributing zl.1,097,000. I think the project has been singled out for co-financing [by the NCBR] not only because of its scientific potential, but also because it has considerable commercial potential. I think the experts evaluating our proposal— who are familiar with how software is created—simply saw it as an opportunity in the same way as we did. In Poland we have the best programmers who have been winning international competitions for years. It’s high time that Polish programmers start creating innovations for the whole world. Who will buy your product at home and abroad? This will be a product for software developers whose work is needed in almost every field of business. Software development companies form a market that has been growing at a rate of several to more than 10 percent a year. In the United States alone there are about 45,000 independent software development companies. Of course, we have no intention to limit ourselves to the U.S. market. After all, software is produced all over the world. So the demand is enormous. The program began in June this year and will last two years. Project co-financed by the European Union under the European Regional D e ve l o p m e nt Fu n d 5 TECHNOLOGY BRIDGE TO THE FUTURE An innovative bridge from composite materials is being built at Błażowa near the southeastern city of Rzeszów in a project co-financed by the National Center for Research and Development (NCBR) using European Union funds. This hi-tech bridge will replace an existing facility that is in poor condition and will be the first such bridge in Poland and one of a few facilities of its kind in Europe. T he project is being carried out by the Com-bridge consortium led by the Mostostal Warszawa company with the participation of the Rzeszów University of Technology and the Warsaw University of Technology as well as the Promost Consulting company from Rzeszów. The National Center for Research and Development has allocated zl.5,150,000 for the project under its Demonstrator+ program. The bridge will be lighter and more durable than traditional bridges thanks to the use of special composite materials, says the project manager, Juliusz Żach from Mostostal Warszawa. “These materials have better mechanical properties than steel and are more resistant to corrosion,” Żach says. The project includes the design and construction of the bridge as well as static and dynamic tests and monitoring services. All of these tasks are divided between the four partners in the consortium. Researchers from the Warsaw University of Technology are testing in their laboratories samples of the composites from which the bridge will be built. Researchers at the Rzeszów University of Technology, in turn, are testing the actual bridge components produced. “The composite materials from which the bridge will be made were tested earlier,” says Żach. “We already know what profile of the bridge beam—which means its geometry—will work best. Mostostal Warszawa carried out all the work as part of earlier projects financed 6 by both the NCBR and from funds available under the [European Union’s] 7th Framework Programme. The results of this work were used as the basis for designing the Com-bridge technology demonstrator.” The bridge will be made from materials containing carbon and fiberglass, embedded in a polymer resin matrix. Such materials are used in aviation. For example, the Boeing Dreamliner range of airlines is built from composites. No one before has built a similarly sized bridge using this technology in Poland—though small footbridges have been constructed. The problem is that no standard guidelines exist for composite bridges. The design must be accompanied by a study confirming that the bridge will be safe. The Promost Consulting company is responsible for handling these procedures. Many practical dilemmas need to be solved when building such an innovative bridge—for example how to combine components to ensure durability. Researchers at the Rzeszów University of Technology are responsible for carrying out such tests. Prof. Tomasz Siwowski heads the team from that university. The bridge will be based on four beams. Before Mostostal Warszawa manufactures these, it will first produce a trial beam for tests. The beam will be tested at the Rzeszów University of Technology using a special machine. It will subjected to heavy loads until it is destroyed. In this way, the researchers will determine the TECHNOLOGY strength of the future bridge component. Only then will it be possible to embark on the production of the four beams that will form the supporting structure of the bridge. The Rzeszów University of Technology will also test some smaller components of the bridge, including the joints and the bridge deck. The Warsaw University of Technology Research Center managed by Rafał Molak, Ph.D., is testing finished materials designed by Mostostal Warszawa and Promost Consulting. Composites are materials made from two or more constituent materials with significantly different physical or chemical properties that when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons: common examples include materials that are stronger, lighter or less expensive than traditional materials. Composite materials are generally used for buildings, bridges and structures such as boat hulls, swim- ming pool panels, race car bodies, shower stalls, bathtubs and storage tanks. The most advanced examples are used on spacecraft in demanding environments. The properties of a composite can be determined theoretically. But laboratory tests are needed to ensure certainty. Also the conditions under which a composite is produced influence its final performance. Therefore materials studies are necessary, and the Warsaw University of Technology has performed a series of such studies. The old road bridge at Błażowa was built in 1958. Its steel-wooden structure no longer meets modern technical requirements. Due to the poor condition of the bridge, its capacity has been limited to 15 tons. The Com-bridge consortium undertook to dismantle it and build a new composite bridge. The work will be carried out from March to November next year. After the bridge is built, its operating parameters will be examined. The whole project covering industrial research, development and manufacture of a demonstration installation runs from November 2013 to March 2016. Karolina Olszewska Project co-financed by the European Union under the European Regional D e ve l o p m e nt Fu n d 7 MEDICINE OXYGEN MAPS FOR Scientists at the Jagiellonian University in the southern city of Cracow are working on a method to draw up special oxygen maps of tissue in a patient’s body. Such maps are needed in cancer treatment. A doctor referring a patient for radiotherapy can use such a map to determine just how high a radiation dose must be applied to increase the effectiveness of treatment. C ancer tumors have much less oxygen than healthy tissues. The degree of oxygenation of individual cells in a human body also varies. Research conducted by a team led by Martyna Elas, Ph.D., from the Department of Biochemistry, Biophysics and Biotechnology at the Jagiellonian University, has shown that the less oxygen in the tumor, the more difficult the radiation procedure is and the greater dose of radiation is needed. The scientists have conducted an experiment on mice. They implanted an identical cancer tumor in different mice. When the tumor reached a certain size, they administered a specific dose of radiation to the mice. It turned out that the lower the concentration of oxygen in the tissue, the less effective treatment was. When all the cancer tumors were treated with the same dose, depending on the concentration of oxygen at the time of irradiation it was possible to predict which mouse would be cured, and which would not. “We want our oxygen maps to be used in clinics to enable precise and quantitative determination of the concentration of oxygen in tissue. Its influence on the efficacy of radiotherapy is particularly evident in the case of tumors of the uterus, as well as of the head and neck,” says Elas. Cancer treatment is just one of the areas where such oxygen maps can be useful. Another is sleep apnea, or snoring, which may lead to severe hypoxia —a condition in which the body is deprived of adequate oxygen supply—and accelerate the development of cancer. Oxygen maps are also useful in the treatment of stroke, limb ischemia and damaged vasculature, for example in patients with diabetes and hard-healing wounds. Olga Majewska 8 MEDICINE CANCER TREATMENT 9 TECHNOLOGY FUEL CELLS UNDER WATER A doctoral student from the Naval Academy (AMW) in Gdynia, northern Poland, is working to improve the efficiency of robots that are used to check the condition of pipelines at the bottom of the sea and to detect sea mines and enemy ships. 10 TECHNOLOGY J ust how long a robot can stay underwater and how many tasks it can perform depends on the fuel cell that powers it. Adam Polak, a Polish doctoral student from the Mechanical and Electrical Engineering Faculty at the Naval Academy, is working to optimize fuel cell cathodes used underwater. His research has been singled out for praise in the sixth round of the Innodoktorant scholarship program for innovative doctoral students. A fuel cell is typically a device that uses hydrogen and an oxidant to create electricity from an electrochemical process. Much like a car battery, a fuel cell converts chemical energy into electrical energy. Each fuel cell uses an electrolyte and two electrodes. There are different types of fuel cells, based mainly on what kind of electrolyte they use. Many combinations of fuel and oxidant are also possible. The fuel could be diesel or methanol, while air, chlorine, or chlorine dioxide may serve as oxidants. Most fuel cells in use today, however, use hydrogen and oxygen as the chemicals. The efficiency of a fuel cell is key. It influences the running costs of equipment, and how long and how efficiently it performs. “A fuel cell converts chemical energy into electricity,” says Polak. “This requires the installation of auxiliary equipment such as pumps, humidifiers, and condensers. An important role is played by a pump for the recirculation of oxygen in air-free systems. It causes a continuous circulation of oxygen in a fuel cell. I’m going to eliminate this recirculation stage to save energy. If this pump is removed, there will be no need to power it,” adds the researcher. Polak also aims to develop an algorithm to control the flow of oxygen in the system. His work involves both developing the theory and conducting laboratory tests using a model. Polak says his research should be of interest to defense industry enterprises and companies that use a range of underwater devices. Karolina Olszewska 11 MEDICINE ANALYZING ANEURYSMS A young researcher from the Łódź University of Technology in central Poland aims to help doctors precisely diagnose patients with aneurysms— balloon-like bulges in arteries that can be highly dangerous. A neurysms form due to inflammation, injury or disease. Arteries have thick walls to withstand normal blood pressure. However, certain medical problems, genetic conditions, and trauma can damage or injure artery walls. The force of blood pushing against the weakened or injured walls can cause an aneurysm, which can grow large and rupture or dissect. Both a rupture and a dissection can be fatal. Some aneurysms do not cause any symptoms. A rupture of an abdominal or thoracic aortic aneurysm can lead to death and requires surgical intervention, involving the implantation of a vascular prosthesis, a so-called stent graft. This is a cylindrical scaffolding in an impermeable jacket. In smaller vessels, stents without jackets are routinely implanted. Andrzej Polańczyk, D.Sc., a young scientist from the Łódź University of Technology, is working on a project called “The development of a non-invasive method for the selection and optimization of intravascular prostheses.” The project has received zl.1.2 million in co-financing in the fifth round of the National Center for Research and Development’s Lider (Leader) program. The project will get under way in January. Polańczyk became interested in the formation of blood clots in vascular prostheses after being inspired by research conducted at the Medical University of Łódź. He developed a model of thrombus formation that makes it possible to predict potential dangers before surgery involving the implantation of a vascular prosthesis. The model also enables doctors to assess the risk of post-graft complications. After collecting and analyzing detailed medical data, a team of researchers including Polańczyk wants to construct three-dimensional fragments of a patient’s cardiovascular system, using 3D printing technology. This will make it possible to test various types of vascular prostheses in blood flow conditions specific to a particular patient. The next step will be to develop a mathematical model to simulate blood flow in a patient. “By using our diagnostic system we can help companies that produce vascular grafts, highlighting areas at risk of post-graft complications and thus facilitate the choice of a particular type of prosthesis for a specific patient,” says Polańczyk. Danuta K. Gruszczyńska 13 MEDICINE DOUBLE WHAMMY AGAINST BREAST CANCER Angelika Kaczyńska, a young researcher from the Faculty of Biology at the University of Gdańsk in northern Poland, is exploring the possibilities of combining pharmaceuticals with natural biologically active substances in the treatment of breast cancer. K aczyńska is taking part in a project led by Prof. Anna Herman-Antosiewicz that involves studying biologically active compounds of plant origin for their anticancer properties. Some cancer cells exhibit resistance to drugs from the start, others may acquire such resistance with time, Kaczyńska says. Breast cancer is the most common cancer in women worldwide. Patients with a high level of HER2 receptor protein have a poor chance of recovering. This applies to 25-30 percent of all cases of the disease. Kaczyńska aims to change these statistics. To this end, she proposes a combined therapy in which anti-cancer drugs are supplemented with natural biologically active substances. She is examining how the substances combined impact breast cancer cells overexpressing HER2 protein. The first group is commercial drugs used in therapy. The second group are plant-based biologically active compounds called isothiocyanates. These occur naturally in cruciferous plants such as Brussels sprouts, cabbage, cauliflower, broccoli, radish and arugula. “Isothiocyanates are formed through the breakdown of larger organic compounds called glucosinolates under the influence of an enzyme called myrosinase. Additionally, they are easily absorbed by the body,” says Kaczyńska, who is a winner of the sixth round of the Innodoktorant scholarship program for innovative doctoral students. The innovativeness of the project lies in the fact that the new kind of treatment will be directed at several targets at the same time. There is a chance that this combined therapy will reduce the invasiveness of cells overexpressing the HER2 receptor and the speed at which 14 they spread in the body. For now, the research is being conducted on a cell model in a procedure called in vitro simulation. This allows researchers to track the process whereby cells develop resistance to drugs. The tests are being conducted on human cancer cells grown in laboratory conditions. The HER2 protein, which is present in the cell membrane, belongs to a family of receptors related to growth factors. It is one of the regulators of growth, migration and differentiation of cells as well as formation of capillary blood vessels. The most popular drugs prescribed for women with breast cancer exhibiting overproduction of the HER2 receptor exclusively block the action of the receptor. However, they do not target certain important proteins that are responsible for the transmission of signals from HER2. The increased activity of these proteins enables cells to develop resistance to drugs. In her method, Kaczyńska is aiming to target not only the receptor, but also these particular proteins. “This is supposed to be a double impact kind of effect. The drug targets the receptor, and the vegetable compound targets receptor proteins. I’m researching several different combinations. Each involves the use of a very small dose of one of the commercial drugs in combination with one of the isothiocyanates: sulforaphane, erucin or sulforaphene,” says Kaczyńska. She adds that the smallest possible amount of the traditional drug should be used. This is important because currently used doses cause many undesirable side effects, such as fever, rash, vomiting and diarrhea. “My goal is to develop a method that on the one hand will produce a stronger effect compared with the effect of the drug itself, and on the other hand minimize the risk of adverse effects. There is a long road MEDICINE from in vitro studies to treatment for patients, one that involves a series of analyses and tests. However, isothiocyanates seem to be a promising anticancer agent,” says Kaczyńska. Earlier findings suggested that sulforaphane, one of the best known isothiocyanates, prevents the formation of cancer cells. Research by the Herman-Antosiewicz team showed that sulforaphane effectively inhibits the growth of breast cancer cells belonging to many different cell lines. However, nobody earlier used isothiocyanates for commercial drugs or tried to develop such a therapy method. It is already known that such a method inhibits the growth of cancer cells, including those resistant to drugs, more effectively than the drug itself. The combination of the compounds used effectively inhibits cell division and migration of cancer cells. If the treatment proves successful in in vivo conditions it could not only inhibit the growth of the primary tumor, but also prevent drug-resistant metastasis. “The results of my research suggest that the tested combinations are far more effective than any of the compounds tested separately. I already know that this kind of therapy works in in vitro conditions. The next stage will be tests on laboratory animals. They will confirm whether or not this kind of therapy using isothiocyanates has the potential to enter a phase of testing on humans in the future,” says Kaczyńska. Karolina Olszewska 15 HEALTH SCRUTINIZING SUPERFRUIT Researcher Magdalena Kupska from the Gdańsk University of Technology in northern Poland is developing tools for evaluating select types of fruit with strong health-promoting properties. S ome of these naturally occurring and genetically unmodified types of fruit are changing the food market, the cosmetics industry and the pharmaceutical sector. One of these wonders of nature is Physalis peruviana, a small, orange-colored fruit with an intense flavor reminiscent of kiwi, strawberry and gooseberry. Physalis peruviana is a genus of plants from the nightshade family and native to the Americas. The plants produce small orange fruit encased in a lantern-like husk and similar to the tomato. Since it has a mild, refreshing acidity similar to the tomato, it can be used in much the same way. Many Physalis species are called groundcherries. Much like the chokeberry and Kamchatka berry, Physalis peruviana is regarded as a superfruit that contains healthy bioactive compounds. These compounds neutralize free radicals and heavy metals and have an antiinflammatory, anti-cancer, antibacterial, antifungal and anti-allergenic effect. 16 There are many types of superfruit. To learn which of them have the most biologically active compounds, precise analytical methods are needed. Kupska, who won a scholarship in the sixth round of the Innodoktorant program for innovative doctoral students in Poland, is working to develop such methods under the supervision of Prof. Jacek Namieśnik and Justyna Gromadzka, Ph.D. Kupska’s research provides information about the contents of selected fruit compounds. “Until now, no methods were available to make it possible to detect, identify and quantitatively evaluate a broad spectrum of compounds in food products,” says Kupska. Some of these compounds are difficult to put a finger on because they undergo various transformations. The process of isolating these compounds from the fruit is not an easy task, either. This is done with the help of modern analytical techniques and topclass equipment used by the Department of Analyti- HEALTH cal Chemistry at the Gdańsk University of Technology’s Faculty of Chemistry. Among fruit rich in health-promoting compounds, chokeberry has proved a hit on the Polish market, especially as the climate in Poland is conducive to its cultivation. Chokeberry is widely used to color food products, especially fruit juices, because it has an intense red color. The tart taste of this fruit makes eating chokeberry straight from the bush a somewhat daunting experience. But it can be used to make jams, especially when combined with apples, for example. It is also perfectly suited for use as a key component of liqueurs or wines. Moreover, like other superfruit, it can be used for the production of dietary supplements. Though many juices in Poland are colored with chokeberry, it is not always possible to find this information listed among the ingredients. Nevertheless, chokeberry has a lot of health-giving properties and even small amounts of it add to the health value of juices. The analytical procedures being developed by Kupska are expected to allow for a quick and comprehensive evaluation of healthy compounds in fruit. This will facilitate the introduction on the market of new foods, rich in health-promoting ingredients. The results of the research will be used not only in the food industry, but also in the cosmetics industry. Bioactive compounds include essential oils (terpenes) such as menthol, which is used in chewing gum, for example. Pleasant scents found in fruit and flowers can be isolated and added as natural ingredients to perfumes, shower gels, lotions and creams. And the super-antioxidants contained in fruit can be used for the production of cosmetics. Kupska has authored several publications in international scientific journals and papers delivered at international conferences. Karolina Olszewska 17 INNOVATION SMART GLASSES OFFER Young Polish inventors from the western city of Poznań have developed a computer imaging system using a pair of special glasses that make it possible to see farther and in more detail than with one’s own eyes. The system, inspired by virtual reality technology, can come in handy in road traffic, field observations, and even when going diving. T he glasses make it possible to see yourself from the back and see a much larger area than normally—at least twice as large or three times larger. Today divers wanting to see large areas of the underwater world often use expensive cameras that they place on a spe- 18 cial extension arm. The glasses designed by the Poznań inventors could enable divers to observe a wide area in real time. The invention also helps improve traffic safety. “By placing the camera behind the vehicle, the driver can see more, for example, when parking the car,” says one of the inventors, Bartosz Barłowski. He adds that the system also makes it possible to deal with the problem of blind spots—the area around the vehicle that cannot be directly observed by the driver through either the rearview or side mirrors. “In video games such technology is used when we want to follow a vehicle or a player. The camera is then positioned behind the figure in question. Our glasses work in much the same way,” Barłowski says. It all started with a competition held by the Intel company for innovative technologies that will be entering use in the coming years. The Poznań inventors made a INNOVATION ENHANCED VISION video for the competition in which they showcased their glasses. “We made the prototype after working away for two days in a garage. We then posted this video on the internet and got a huge response,” says Barłowski, who, together with four other inventors, runs several online “knowledge platforms,” including www.mepi.pl, where he posts content such as instructional video courses. After the release of the video the inventors received a proposal of collaboration from Facebook, which had previously invested in virtual reality technology using special glasses. The inventors also received a lot of questions about when the product would be available. For now, they are at the prototype stage. If large companies take an interest in the project, the system can be quickly put on the market. Then virtual reality glasses could appear in stores within half a year, the inventors say. The inventors did not create their product from scratch. They used existing virtual reality technology and attached two wide-angle cameras to their glasses. There is also a computer controlling the system. The computer is placed in a backpack. The designers now plan to miniaturize their device so that the technology can be controlled by an application in a smartphone without the need to carry a backpack with a computer. If a user wants to look to the right or left, it is necessary to move a joystick. But the joystick is only a temporary component of the prototype version of the device. The designers intend to modify the system so that a movement of the head will be enough to point the camera in the desired direction. There are also plans to improve the performance of the camera. Olga Majewska 19 NUCLEAR RESEARCH SCIENCE VS. NUCL An international research team including Polish physicists has developed a prototype mobile detector of radioactive materials that could help prevent terrorists from carrying out a devastating attack using a nuclear bomb. T he system, which can be used to help prevent illegal trade in radioactive materials, is referred to as MODES SNM. Polish physicists from the National Center for Nuclear Research (NCBJ) in Świerk near Warsaw were responsible for research into innovative pressurizedgas-based radiation detectors as part of the project. The MODES SNM (Modular Detection System for Special Nuclear Materials) project started in January 2012 and is nearing completion. It is a collaborative project funded by the European Commission under its FP7 Security program. Teams of scientists from Italy, Britain, Switzerland, Ireland and Poland’s National Center for Nuclear Research have been tasked with developing a new-generation system capable of detecting weak or shielded radioactive sources. The prototype is designed to help quickly and easily detect radioactive sources, identify hazardous fissile materials, and provide information on shielding used to conceal such sources. The MODES SNM project, with a budget of 3.3 million euros, has been co-financed from EU funds to the tune of 2.4 million euros. The prototype has been successfully tested in some major cargo hubs in Europe. A specially adapted van fitted out with state-of-the-art equipment 20 has traveled more than 6,000 kilometers and visited the seaports of Rotterdam and Dublin as well as London’s Heathrow airport, and some logistic centers in Zurich and Brussels. The prototype was tested in those places during routine operations performed in each port and center. The collected data confirm results earlier obtained during simulations in R&D labs and paves the way to deploying the system in sites such as customs and border service checkpoints. “Special Nuclear Materials, which means materials containing enriched uranium or plutonium, are not easily detectable,” explains Prof. Marek Moszyński from the Detector Physics Department at the National Center for Nuclear Research. “They can be identified by the weak neutron and gamma radiation they emit, however the detectors must be sensitive enough to identify these signals against a natural background, especially when such materials are concealed in radiation-shielded containers in places like cargo containers or truck trailers. MODES SNM-performed screenings are of a short duration and exceptionally effective. We are convinced that the MODES SNM system will find plenty of applications.” EAR SMUGGLING According to Moszyński, who is an internationally recognized expert in the field of nuclear electronics, “illegal trafficking in special nuclear materials that may be used to construct nuclear bombs or even smuggling nuclear bombs themselves are among the most dangerous terrorist activities that pose an unimaginable threat to the world.” Innovative radiation detector technology based on high-pressure gas scintillators was used to build the MODES SNM system. Gas in such detectors can be compressed to a pressure as high as 200 bars. In comparison to classical scintillating crystals, such gaseous detectors are much more robust and cheaper to operate, researchers say. Łukasz Świderski, Ph.D., head of the Detector Physics Department at the NCBJ, says, “The MODES SNM prototype consists of nine detecting modules. Five of them are responsible for detecting fast neutrons; each of them is composed of two cylinders filled with helium-4. Two modules are responsible for the detection of slow neutrons; each of them is also composed of two cylinders filled with helium-4. However, to be able to detect slow neutrons, internal surfaces of the walls of the latter cylinders are coated with lithium-6. Finally, two modules responsible for the detection of gamma radiation are filled with pressurized xenon. Such a setup, coupled with innovative electronics and combined with dedicated data analysis algorithms, makes it possible to identify radioactive materials very accurately.” The MODES SNM system can work for a few hours without an external power supply. Users also value its userfriendly human-machine interface (HMI) that can be synchronized with smart phone and tablet applications. Visual and acoustic alerts inform the user that a threat has been detected. The device meets all International Atomic Energy Agency (IAEA) requirements for mobile radiation scanners. The project was carried out by a consortium of R&D institutions including researchers from Italy, Switzerland and Britain as well as Irish customs services, in addition to Poland’s NCBJ. Work was coordinated by Padua University. The Polish scientists were involved in research focusing on the innovative detection system. They were responsible for tasks such as verification of detector sensitivity, estimation of the time needed to detect a specific activity and optimization of operational parameters. The MODES SNM project should help prevent illegal trafficking of nuclear and radioactive materials, which is particularly important now that EU borders are open and cargo can be freely transported from one country to another. In 2012 alone EU customs authorities processed 139 million import declarations (250 million items), 105 million export declarations (224 million items) and 17 million transit declarations.

T he European Rover Challenge is the European equivalent of the famous University Rover Challenge competition organized by the Mars Society in the United States. The European Rover Challenge was held in Podzamcze near Chęciny in Poland’s south-central Świętokrzyskie province. The competition was targeted at university students, graduates and faculty members. The participating teams were expected to design and build a Mars rover. A total of 10 teams took part. The rovers were expected to perform a series of tasks, including reaching a designated place using GPS and a compass, completing a course as fast as possible, and collecting a soil sample. The designers were not allowed to see their rovers during the contest tasks and had to rely on images from a camera on the vehicle and GPS data. The idea was to simulate the conditions with which a rover must cope during a mission to Mars as closely as possible. For this reason, a special course was prepared for the rovers reminiscent of the surface of the Red Planet. Competitors could score 22 additional points during a presentation before the competition jury. The Wrocław University of Technology team won the competition with its Scorpio robot. The runnerup was the Impulse team from the Kielce University of Technology in south-central Poland. The Wrocław students have taken part in the University Rover Challenge competition in the United States four times, with a continually upgraded version of their Scorpio rover. Overall, Polish teams regularly win the U.S. competition. Students from Białystok in eastern Poland won the University Rover Challenge in 2011 with their Magma2 rover. They won again in 2013 with the Hyperion rover, outclassing rivals and scoring a record 493 points out of a maximum of 500 possible. This year in early June, the team from the Białystok University of Technology proved to be the best again, while the Legendary Rover Team, made up of students from the Rzeszów University of Technology, finished third. “In fact, the rovers designed by the students are not intended to fly to Mars. But they can be useful in testing other devices that are intended to fly to the Red Planet,” said Łukasz Wilczyński of Mars Society Polska. One example is the Magma White rover designed by a team of Polish students from Białystok and Toruń. That rover was used for testing the Wisdom groundpenetrating radar (GPR), which is destined to fly to Mars as part of the European Space Agency’s ExoMars (Exobiology on Mars) mission. Many countries were interested in hosting the European Rover Challenge. Because of the repeated victories of Poles in the University Rover Challenge in the United States, the organization of the European competition was entrusted to Poland. Organizing the competition in Europe opened it to teams that cannot afford to travel to the United States. “Sometimes the trip to the U.S. cost twice as much as the rover itself. Representatives from some countries also find it difficult to get an American visa. Holding the competition in the center of Europe made it possible to significantly reduce the budgets of some projects,” said Wilczyński. The competition was organized by Mars Society Polska in association with the Planet PR agency, the PHYSICS Świętokrzyskie Province Chairman’s Office, and the Regional Center for Science and Technology in Podzamcze near Chęciny. The University Rover Challenge competition in the United States aims to select the best robotic vehicles that could be used to explore the universe in the future. The winners receive prizes and their robots are presented to NASA as potential designs for a Mars exploration vehicle. The annual competition is held in the Mars Desert Research Station, a simulated Mars base in a desert in the state of Utah. Mars Society Polska is a division of the Mars Society, an international organization that aims to promote the idea of a manned mission to Mars and Mars research. Founded in mid-1998, the organization brings together scientists; aerospace engineers such as Robert Zubrin, who has mapped out a plan for the colonization of Mars; astronauts like Buzz Aldrin, who took part in the first landing on the Moon; filmmakers like James Cameron; and writers and other enthusiasts—all of whom share the vision of a human presence on Mars.
