Valentina Luigia CERIANI City/Region: Solaro School: Liceo linguistico “Stefano Maria Legnani” Career intention: business consultant Hobbies: reading books, listen to music e-mail: vale.ceriani@tin.it
City/Region: Origgio School: Liceo linguistico “Stefano Maria Legnani” Career intention: businessman Hobbies: swimming, running, listen to music e-mail: drammy@virgilio.it Nowadays by the advent of the computer in Biology, as in other sciences, it has become possible to work with an enormous quantity of data in a short time. The micro array’s technology is based on genetic researches both on healthy and sick people, in order to underline which genes could be considered responsible for some illnesses. We compared genetic expression of two different groups of people and we built a referring table where the genes are in the rows and the patients in the columns. This matrix is composed of one and zero. The zero represents the normality, the number one shows that in the patient the gene we are speaking about is over expressed or under expressed. We have considered more than 3.000 genes. The Shapley’s index is based on the coalition concept, which is an under set of the whole of players. So in our game, the coalitions are about 23000! It means that any calculus is possible without a strong calculator instrument. We used the “R” program in order to find the index.
City/Region: Turate (Como) School: Liceo linguistico “Stefano Maria Legnani” Career intention: researcher, teacher at the university Hobbies: playing the piano, listening to music, singing e-mail: saravilla@tiscali.it JAPAN SOFT WARE FOR SUPPORTING MODE DETERMINATION Shiori YAMASHITA City/Region: Kagoshima School: Nagata Jr. High School Career intention: Teacher Hobbies: Watching movies, Reading books, dancing This is software for supporting of the mode determination. It is based on Microsoft excel. It is very helpful for scientists who study stones, particularly igneous rocks or granite. They could get the rate of ingredient in a sample instantly with color graphics. It is very important step to know the constituent to study stones. They use this software to analyze the mineral elements by percentage of a sample. In the past, they used to tally the number of small stones, which compose the sample on a paper. It is original software that manages to save energy and time. It is easy for anybody to use and has a simple design. LATVIA CONSTRUCTION AND OPERATION OF SMALL-SCALE AERODYNAMIC WIND TUNNEL Kristaps DAMBIS City/Region: Kegums School: Riga State Gymnasium №1 Career intention: automotive engineer Hobbies: autocross, travelling e-mail: kristaps@osc.lv Most probably you have heard something about the fast Formula 1 fellows like Schumacher brothers. But have you ever wondered why there are so many weird wings and plates all around their racing cars? Or have you ever seen the most modern and fuel efficient vehicles that resemble nothing but a rain drop? In his research project, the author engaged himself in designing, constructing and operating such a test facility that allows studying flow patterns around bodies and aerodynamic forces on them. During various wind tunnel tests, the constructed instrumentation was found to work accurately and to yield meaningful results.

Ever since the 19th century numerous methods have been designed to optimize the rearranging, and they have proven to be particularly useful in such fields as logistics and programming. This project focusses on exploring how particles can be rearranged by means of networks. They identified the ultimate number of particles which can be rearranged by using networks with one entrance and many exits or one exit and many entrances. They proved that this number is equal to the number of ways in which the network can be crossed by a single particle, and have shown why it is true for all networks of such kind independently on any other feature, like crossroads which seem to perplex the movement of particles. ORGANOCLAY PREPARATION AND PROPERTIES Inese SARCEVICHA City/Region: Auce/Dobele region School: Auce Secondary School Career intention: chemist Hobbies: science, culture, philosophy, music, art, literature, sports, photography, communications, activities in youth organizations and projects, theater, volunteering, taking part in interest groups e-mail: ineses_s@auce.lv, sisi@banda.lv The problem of environmental pollution becomes more and more important. An example is the leakage of oil. It is a reason for developing new methods for fighting pollution. Using organoclay is one of these methods. There is a great quantity of Trias clay in Latvia but it is not suitable for industry. As this clay is especially suitable for preparing organoclay, Latvia could take advantage of its raw materials for solving problems of environmental pollution.
City/Region: Vilnius School: Vilnius “Žirmūnai” gymnasium Career intention: physicist-theoretician Hobbies: history e-mail: erikas-g@one.lt It is impossible to get exact results in contemporary many-electron atoms theory, as in all other many-particle quantum systems. At this point new methods are very important. One of them is isospin method. In this new method all main atom theory quantities can be determined. For this purpose we gained original results. The mathematical aspect of isospin formalism was explicated, the main theoretical relations and expressions were found, that are necessary for the main atomic quantities (coefficients of fractional parentage, transformation matrices, physical size operator’s matrices elements and etc.) analysis.
City/Region: Varena School: Varena secondary school “Azuolas” Career intention: medicine Hobbies: dancing, listening to music, singing, traveling, taking part in various contests e-mail: guleraatajeva@yahoo.com The accident at the Chernobyl nuclear power-plant in 1986 constructed a laboratory for a large-scale experiment, designed to study spread of radioactive pollution over huge areas. There are well known climatic, meteorological, geologic, topographic etc. factors, influencing uneven distribution of the radioactive nuclide 137Cs. However, the path of Chernobyl radioactive cloud, crossing the iron ore fields near town Varena (Lithuania), predetermined favorable circumstances to study the influence of serpentine magnetite ore deposits on redistribution of the radioactive pollutant 137Cs. Taking into account identical meteorological, geologic and topographic factors in the studied zones, and the fact that the 137Cs radionuclide is carried by the smallest aerosol fraction, we propose a hypothesis: lower mushroom radioactivity above the serpentine magnetite ore deposits could be explained by the influence of the natural magnetic fields, producing magnetic anomalies in those areas. Finally, we suggest to employ artificial magnetic fields for protection of important areas from 137Cs contamination in case of accidents, followed by radioactive pollution, or to cover nuclear power- plants with protective magnetic shields to prevent radioactive nuclide leakage by air.

68 69 THE PROPERTIES OF ADAPTATION OF CRANBERRIES TO PH OF SUBSTRATE IN VITRO AND EX VITRO Rugilė STANYTĖ City/Region: Babtai, Kaunas district School: Kaunas district Babtai Gymnasium Career intention: biochemist, biotechnologist Hobbies: dancing e-mail: ru-gile@one.lt The aim of the project was to investigate the properties of physiological and morphological changes during adaptation process of American cranberry to unoptimal acidity of substrate in vitro and ex vitro. The investigation was carried out with three cultivars of cranberry: ‘Bergman’, ‘Bain 10’ and ‘Black Weil’. The change of morphological parts of plant during the adaptation process was measured. The amount of monosaccharides in microshoots growing in medium of different acidity was evaluated by using high-pressure liquid chromatography. The impact of photon flex density and wavelength on ‘Bain 10’ microshoots adaptation process was investigated. It was established that ‘Bergman’ and ‘Black Weil’ are more adaptive to the pH of substrate than ‘Bain 10’. Also, light of different wavelength may influence microplant’s reaction to different acidity of nutrient medium. The investigation has shown that the change of the amount of monosaccharides in microshoots depends on the acidity of medium. It is supposed that pH of substrate has influence on photosynthesis mechanism in plant and the amount of monosaccharides characterize the level of adaptation. LUXEMBOURG CARTOGRAPHY OF GALLS Eric DELE City/Region: Ehlange School: Lycee de Garзons / Esch-Alzette Career intention: architect, pilot Hobbies: nature observation e-mail: gips_eric@hotmail.com Our work deals with the autumn galls found in the area Lei (near Dudelange) and the area Leiffrachen (near Kayl), both situated in the south of the Grand Duchy of Luxembourg. We formulated two questions and tried to get suitable answers to the following: – Which gall-builders are to be found during autumn in the selected area? – Which kinds of animal species are resulting by being cultivated in the galls produced by Diplolepis rosae? As a result we came to the following statements: We could prove with their identification, the existence of 8 gall-builder species in the Lei area and 11 gall-builder species in the Leiffrachen area. We identified for the first time the existence of one species, namely Cryptomyzus ribis (currant blister aphis), in the iron mine area of the Grand Duchy of Luxembourg. Another rare species, Neurotems fumipennis, was found again, 95 years after its first notification in the Grand Duchy. Further investigation would be required in order to be able to conclude if the gall-builders are driven out by civilization and its accompanying symptoms.
City/Region: Randaberg School: International school of Stavanger Career intention: Medicine Hobbies: Music Clarinet, hiking, handikrafts, Origamy, Reading e-mail: narula@broadpark.no Ants (Hymoptera Formicidae) are foraging insects that damage food and property but have their place and use in the ecosystem. For most people they are a nuisance and pest. According to Indian folklore many household spices have been used for repelling ants and other insects that enter the house. It is believed that plants have evolved ways to repel ants, as ants are poor pollinators, and thus plants may emit chemical toxins in their nectar or essential oils. Spices are direct plant products, and so they may contain ant repellant toxins and essential oils. The purpose of this project is to identify and evaluate the ant repelling properties of certain household spices. The aim is to find natural products that are effective at repelling ants, safe to use in a household situation, biodegradable, and are easily available.
City/Region: Bugibba School: St. Aloysis College Career intention: Lawyer or Medical Doctor Hobbies: Reading, travelling, playing piano and listening to music e-mail: rhea@maltanet.net Mark ABELA City/Region: Naxxar School:Saint Aloysis Sixth FormCollege (Birkirkara) Career intention: Cardiovasсular surgeon Hobbies: Playing handball and football, socializing, learning biology, making new friends e-mail: abelamark@hotmail.ru The aim of this project is to produce biogas from grinded waste organic matter, cut by 2 S-shaped blades powered by a 230V motor with a 50Hz frequency and with a maximum input power of 350 Watts. The matter is then preserved in a black-sprayed plastic container, which can absorb heat from the surroundings, hence facilitating anaerobic digestion. An extractor, when switched on, creates pressure so that the gas enters a container and is kept there, due to the presence of one-way valves. When another valve is opened, the flammable biogas is ignited, generating renewable energy. The sludge in the containers can then be dried and used as compost.

70 71 POLAND RELIEVING STRESS IN DOGS IN A HOMELESS DOG SHELTER BY MUSICOTHERAPY Kaja GIZEWSKA City/Region: Szczecin School: The King Mieszko I High School №2 Career intention: doctor Hobbies: skiing, volleyball, sailing, traveling, music e-mail: kaja@px.pl The homelessness among dogs is an increasing problem. The shelters for homeless dogs are the “lesser of two evils”. Unfortunately while staying there the dogs are exposed to the bad impact of a prolonged stress. The aim of this project has been an attempt to relieve stress in dogs by applying the selected compositions of classic music. The animals were observed both in normal conditions, and in the course of music therapy, additionally with analyzing the differences in noise level. She found that the reaction of dogs has individual character. However, most animals calmed down at the sounds of music and the amount of aggressive behaviours diminished. THE HISTORY OF DISCOVERING AND EXPLORING BD+14° ECLIPSING CONTACT BINARY Agata KARSKA City/Region: Cuiavia School: Nicolaus Copernicus University Career intention: astrophysicist Hobbies: astronomy, photography, intercultural learning e-mail: ad-astra@wp.pl Agata has been interested in variable stars which, unlike ordinary stars, mostly change their brightness regularly with periods of hours, days or years. In previous two years she travelled 60 km nearly every weekend from her home to the Torun University Astronomical Observatory in Piwnice to survey large areas of the sky in search for variability. During analysis of the collected data she discovered some completely new, short period variable stars. One of them: BD+14°5016 appeared to be a very special system consisting of two stars with a hot spot between them. Further investigations of this system resulted in interesting conclusions about such stars in general.
City/Region: Szczecin School: The Stefan Czarniecki High School №6 Career intention: psychologist Hobbies: theatre e-mail: ZZ@asternet.pl Contemporary agriculture is strictly connected with common use of artificial fertilizers and plant protection chemicals, among others herbicides. Apart from desired effect of weed elimination, applied herbicides may also cause imperceptible changes in the development and activity of soil microorganisms. The aim of this project was to evaluate the influence of a new herbicide on entomopathogenic fungus Metarhizium flavoviride – one of the most important insecticidal fungi. Kamila found that each concentration of the herbicide inhibited its growth but even the highest concentration of the herbicide didn’t kill the fungus. Kamila’s conclusion is that the use of herbicides leads to qualitative changes in ecosystems and may limit the role of microorganisms as natural insecticides. PORTUGAL ALGAE OF SERRA DA GARDUNHA – CONTRIBUTION FOR THEIR KNOWLEDGE Ana In ê s RONDA ˜ O City/Region: Fundão School: Escola Secundária com №3 Ciclo do Fundão Career intention: biochemist Hobbies: listen to music, make friends e-mail: inesrondao_1@hotmail.com
City/Region: Fundão School: Escola Secundária com №3 Ciclo do Fundão Career intention: biochemist Hobbies: read, watch TV, swim e-mail: andreiacatarina_84@hotmail.com With this work we wanted to contribute to the knowledge of the algae from Serra da Gardunha; associate the diversity and abundance of algae with environmental conditions and improve our knowledge about the algae role in the maintenance of the trophic chains of the local aquatic ecosystems. The conclusion are: * clorophyta was the division that was observed frequently while rodophyta was observed only in Ribeira da Barbara; * the algae development is better in places where environmental conditions are stable.
City/Region: Alcongosta School: Escola Secundária com №3 Ciclo do Fundão Career intention: doctor, biochemist Hobbies: read, watch TV, listen to music, mode e-mail: dorasmh@hotmail.com ANTIOXIDANT ACTIVITY OF HEATHER David VICENTE MEDROA City/Region: Seia School: Escola Secundária de Seia Career intention: engineer Hobbies: listen to music, play computer e-mail: davidmedroa@hotmail.com Heather is a common shrub in “Serra da Estrela” whose flower heads are used in folk medicine. An extract of this plant was made and used to assess its antioxidant properties. The heather extract that I prepared showed significant antioxidant capacity, as it can be seen by the results obtained on protection against lard peroxidation. Although lard used in my experiments already has an antioxidant as additive, the heather extract demonstrated the capacity to increase still more the protection against peroxidation in a significant way. Probably this activity is due to flavonoids that are present in the heather extract, because they are known to act as good antioxidants in several conditions, and a variety of them were already identified in this plant.
72 73 HOLOGRAPHY MADE EASY, THE SANDBOX SYSTEM AND PORTABLE SYSTEM Alexandre LOPES City/Region: Aveiro School: Escola Secundária Jaime de Magalhães Lima Career intention: particle physicist Hobbies: play the guitar, reading, computer programming e-mail: kezacolt@msn.com, kezacolt@gmail.com This project is the result of several years of experience. I had the idea to miniaturize the classic process to make holograms because it was heavy, and because it was expensive. After the sand box system was tested, the first good results were achieved. Today, the project aims at two main objectives: – from a scientific technological point of view, to prove that a low-priced set of an holographic system may give good results, as a professional set does; – from a scientific sociological point of view, to facilitate the spread of science, with an easy way of doing it, as a seed to promote the contact with physics. Remotely, the portable system may be replicated in order to reach a wide range of schools.
