Aranese and Gardiol: phonetic study about two poles of the Occitan language.

Spain, Social sciences
Roger Ferran i Baños
Aranese and Gardiol, phonetic study about two poles of the Occitan language compares the phonetics of these Occitan varieties showing their differences to determine if Occitan is a single language or not. In order to do it, a very extensive study is required; but I could only study from this point of view because my High School limited my work in 70 pages. Therefore, my project cannot completely demonstrate if we are talking about one or more languages. But, despite all, as there is mutual intercomprehension between both varieties and the so-called standard Occitan (Languedocien), it is possible to classify Occitan as a single language. This project has also another objective: to divulgate what are Aranese and Gardiol, because although Occitan is official in Spain (in Catalonia), it is an unknown reality and a seriously endangered language.

Aspirin and salicylic acid in the combination with inhibition of PI3K promote cell death in malignant melanoma

Slovakia, Medicine
Emília Petríková
Aspirin – acetylsalicylic acid and salicylic acid are anti-inflammatory drugs. Because of their acts on cyclooxygenases and NF-kappaB, aspirin and salicylic acid are recently tested as a cure for various types of cancer. Malignant melanoma is a very dangerous type of cancer responsible for 75 % of death realted to skin cancers. There is still a lack of effective treatment of melanomas. We decided to try the ability of these drugs to suppress the proliferation of melanoma cell lines. Tests of cell viability and Western blot assays showed that aspirin or salicylic acid could be used to trigger apoptosis in malignant melanoma cells when they are combinated with Gossypol, an inhibitor of PI3K. These results can help in finding a treatment for malignant melanoma in future.

Astrobiology: to what extent can life-supporting amino acids form on cosmic dust?

Denmark, Chemistry
Alexander Mørch
Astrobiology and Amino Acids We know a surprising amount of information about how the universe was created. We know a surprising amount of information about how the Sun came about and how its planets formed around it. But the concept of how life evolved on Earth remains an unresolved albeit miraculous mystery. My project is focused on investigating the origin of some of the key molecules believed to have been involved in reactions intricately linked to life – molecules like amino acids. Research is indicating that the Earth’s initial supply of amino acids was from outer space, which is why scientists have been searching for them in extraterrestrial environments for years on end. I believe to have found a molecule that can act as a precursor to amino acids and is perhaps even responsible for our presence in the universe.

Automated system for searching deffects and quantitative evaluation of damaged surfaces

Ukraine, Engineering
Illya Litkin
Problem of flaw detection is actual in modern industry and science. Typical defects of surfaces are cracks. The aim of the project was to create automated system for fixation, visualization and calculation of quantitative characteristics of cracks and other formations on solids with help of computer technologies. The main task of research was creating technical complex (mini lab) for visualization and processing images by computer program for evaluation quantitative characteristics of defects on solids surfaces. For visualization surfaces we proposed mini lab consist hand made microscope (500 times enlargement) with USB output and computer. Computer program for processing was created with special algorithm that was invented by us. Offered method and computer program is universal for researching micro and macro surfaces. Processing photos by special programs on the spacecrafts and sending final results as tables and plots can be effective because much important information about planets formations and inside processes we can get from cracks on the surfaces.

Autonomous Arduino-based recirculation of radiosondes

Switzerland, Engineering
Alex Hönger, Nicolas Mesot
In our work we analyze the feasibility of an autonomic return of radiosondes. These instruments are used to measure different atmospheric values up to 30 kilometers height. Daily, over 1000 radiosondes are started and many of them will never be found. Our idea is to bring them back with a glider. The first part of our work deals with the feasibility at many different degrees (economic feasibility, legislation, physical and technical feasibility etc.). The second part was to program an autopilot for a model airplane in the field of vision of the pilot in sort to gain experience for the prosecution of our final goal, an automatic system to bring back radiosondes to their starting point.

Connection Between Optimization Programs and Quantum Chemical Software Packages: Its Use in Exploring Hypersurface of Potential Energy

Czech Republic, Computing
Lukáš Červenka
Today, various optimization algorithms exist which can effectively find stacionary points of functions. There are also quantum-chemistry software packages which contain different types of energy computation. The software package I made represent a novel software bridge between these two groups of programs. The main function of the developed software package is to find stable structures or structural isomers of, in principle, any molecule. The developed bridge has been applied to finding classical equilibrium structures of ionized clusters of helium HeN+, N = 3 - 10. These clusters are very important in modeling of cold helium plasma which has been shown recently to have great potential for medical applications (non-destructive and highly efficient sterilization, chronic wounds healing). The use of cold helium plasma jets in medicine is currently extensively investigated by several laboratories worldwide.

Constant diameter sets and their applications

France, Mathematics
Fabian Rainouard, Margaux Le Brun
For two years, we have been working on constant diameter sets. They are flat geometrical figures with a distance between two points which is always inferior or equal to the diameter. The circle is an example of constant diameter set but there are many others. After drawing and building some models of these sets, we tried to work out properties that they could have. Then, we did a study in 3D. For a few months we have been thinking about applications of the theory. Cams and British coins are the most famous applications. But the application to tubular boilers is an innovation. Moreover it’s a good illustration of the properties of constant diameter sets and could result in a patent.

Daylily (Hemerocallis L.). A New Method of Breeding and Cultivation

Lithuania, Biology
Edvinas Misiukevičius
Over the last 10 years daylily breeding has reached its peak, however, the majority of daylily varieties are created in the U.S.A., thus making them barely resistant to the Lithuanian climate. Hence, I decided to create a new variety of daylilies resistant to the climate of Lithuania. To fasten the process, I decided to grow the seedlings indoors, which shortens the bloom time to 9 months. I investigated 3 main factors: temperature, pollination time and ploidy (tetraploid or diploid), and found that the best time for crossing daylilies is 10 a.m., the most efficient temperature is 18-20 °C, and the diploids set pods better than tetraploids. The main result is a new variety of daylily – Hemerocallis ‘Mitsu’, which I tested for 3 years, and it grows well after winter.

DeafTalk – analysis and recognition of human gestures

Bulgaria, Computing
Nikolay Dakov
The project analyzes one very interesting problem - the recognition of human gestures. It is separated in two parts. The first part of the project is a library for recording and recognizing gestures. It is useful for the developer community because it is easy to use and effective. It can be used for creating modules in existing software. In general, it will be capable of improving the user experience regardless their speaking and hearing disabilities. The functuality of the library is based on a combination of Kinect and advanced machine learning algorithms like Hidden Markov Models and Support Vector Machines. The second and more important goal of the project is to facilitate in the communication of deaf people by creating products that uses the library and can recognize the sign language. This can help many people and make their lives easier and better. Taking into account the relevance of our system, we hope that it will find applications in many different fields.

Determination of the temperature and spectral classification of stars: an experiment in astrophysics

Portugal, Physics
Sofia Fernandes, Pedro Oliveira, Ana Sofia Lopes
The experimental Astrophysics project in the spectroscopy area is aimed to obtain star temperatures and its spectral classification. Thus, two different methods were used accordingly to the star’s emission peak whether within the “visible” spectrum or not: 1- The first method enabled us to accomplish the estimation of the star temperature applying Wien’s law, taking into account the wavelength where the stars has the maximum flow. 2- The second method consists in using a Plank curve (black body radiation fit) applied to a spectrum, and therefore we estimate its temperature. It is to mention that our project can be easily replicated in various schools throughout the world as an effective and interesting experimental exercise in astronomy.
