INTRODUCTION

Faculty of Science of P. J. Šafárik University in Košice was founded in 1963 and since

that time it has educated more than 5 000 graduates of both, single and joint degree

programme studies in all branches of natural sciences. Within the European Union adopted

model 3-5-8, the Faculty provides the Bachelor's and Magister's degree studies in the

following branches: Biology, Chemistry, Environmental Ecology, Geography, Informatics,

Mathematics and Physics as well as all joint degree programmes in combinations of Biology,

Chemistry, Geography, Informatics, Mathematics and Physics. Since 2006, in cooperation

with Institute of Filological and Social Sciences joint degree programmes in combinations

with Physochology, Philosophy, Slovak language and Briyish and American studies were

opened.

As a respected research institution, the Faculty offers also PhD study programmes in

fifteen accredited fields of science for graduates from Slovak and foreign universities. The

education at the Faculty of Science is provided by experienced teachers who carry out also

research and closely co-operate with Slovak and foreign universities and research facilities.

The research at the Faculty of Science at Šafárik University in Košice shows

multidisciplinary character and due to this it covers a wide range of topics from molecular

biology to computer and material sciences. The research in 2007 in the field of Biology and

Ecology was directed towards the problems of biodiversity of plants and animals,

biotechnology of medicinal plants, carcinogenesis, prevention and cancer therapy; in

Geography the research was aimed at hydrology of the Slovak karst. Research in Chemistry

focused on synthesis and properties of new compounds with biological activity, new materials

and new analytical methods. Research in Informatics was concentrated on fuzzy techniques,

neural networks, logical programming and preparation of web-university, in Mathematics it

followed the ideas of graph theory, algebraic structures, differential equations and topology

and in Physics it was concentrated on development of new magnetic materials, theoretical and

experimental research of low-dimensional magnetism and quantum liquids at ultra-low

temperatures, nuclear collision studies and photodynamic effect. The research was also

carried out in the fields of theory of teaching of biology, chemistry, informatics, mathematics

and physics. High percentage of the scientific outputs is done in the co-operation with foreign

universities or research facilities.

Graduates of the Faculty find positions not only as researchers and secondary school

teachers but they can successfully work in the business sphere and public administration.

Some of them successfully undertake doctoral study or postdoctoral training abroad to be well

accepted in the European labour market. New forms of further long-life education as a part of

service done to society are provided for graduates of the Faculty of Science as well as for the

public. The RNDr. (Rerum Naturalium Doctor) examinations, qualification examinations,

various courses and training projects are to be mentioned. In accordance with European

documents on higher education the Faculty uses the credit-based system in line with the

European standard ECTS. Joining the European SOCRATES/ERASMUS programme

promoted the possibility for our students to undertake a fully recognized period of study at

EU universities as an integral part of their degree and academic qualification as well as

allowed to the students from EU countries to undertake a semester or two of studies at our

faculty.

STRUCTURE OF FACULTY

The administrative structure of the Faculty of Science is based on larger institutes

incorporating individual departments. The head of each institute is Director (Professor or

Associated Professor) and the Council of the Institute formed of full-time Professors and

Heads of departments. This structure enables better organization of the pedagogical and

scientific life of the Faculty.

During 2007 reorganisation of the administrative structure of the Faculty took place.

From September 1, the Institute of Social Sciences splitted off of the structure of Faculty of

Science and also the Detached Unit in Rožňava became a part of the administrative structure

of the University. Nevertheless, the Detached Unit in Rožňava continued to provide Bachelor

study programme.

Within the Faculty are active also the Centre of Applied Computer Science (developing

the Academic Information System) and the Centre for Lifelong Learning organizing other

forms of educational activities and European projects are included within the structure of the

Faculty.

RESEARCH HIGHLIGHTS

Faculty of Science of P. J. Šafárik University in Košice is included in the group of

research faculties, which put strong accent on research as an integral part of their mission.

Multidisciplinary character of the Faculty is a good prerequisite for interdisciplinary approach

and integration of scientific activities. After entering into European structures the priorities of

the Faculty are integration into European research area, improving the quality of scientific

outputs and PhD study, increasing the stream of financial sources for scientific activities, re-

building of research and information infrastructure of the Faculty and extension of services in

community, business, research, developmental, industrial and agricultural facilities in

Slovakia.

In 2007, the Faculty has continued to improve the quality of several excellent research

laboratories: Laboratory of NMR spectroscopy, Laboratory of spectral methods, Laboratory

of thermal analysis and Laboratory of structure analysis of biomacromolecules (Institute of

Chemistry), Laboratory of flow cytometry and Laboratory of cell cultures (Institute of

Biology), Laboratory of low temperature physics with new helium liquefier and MPMS

SQUID as well as PPMS apparatuses, Laboratory of biophotonics and Laboratory of

advanced computer technologies (Institute of Physics) as well as the Laboratory of GIS

(Institute of Geography).

In these and other laboratories worked more than 220 university teachers and

researchers together with about 90 doctoral students. This staff is involved in up to 140

scientific projects supported by both, grants for fundamental research from the Slovak grant

agencies: Slovak Grant Agency for Science (VEGA), Slovak Agency for Science and

Technology (APVV), Slovak Cultural and Educational Agency (KEGA), and foreign sources

of funding such as EU FP6 projects, COST Agency, DAAD (Germany) and other institutions.

Moreover, young researchers were supported by internal grant systems (VVGS) at the

university as well as faculty level. In 2007, the University and Faculty supported 25 and 25

VVGS projects, respectively.

Excellence in research measured by international standards is a first objective of our

research teams. Within the Faculty, a Centre of excellence for low-temperature physics was

established. In applied research, the main attention is paid to pharmaceutical,

17

pharmacological, chemical and material research. Continuous increase in funding sources for

research is caused by the growing activity and comes from research grants and contracts. It

exceeds the average grant income of the Slovak universities, year after year it becomes more

and more important part of the budget of the Faculty (in 2007 grants made up 85.25 % of the

overall budget-see the graph).

Selected Results

VEGA 1/4321/07 (Bojková):The effects of peroral antidiabetic agent metformin on basic tumor growth parameters, metabolic and hormonal variables in chemically-induced mammary carcinogenesis in female Sprague-Dawley rats were studied. The results are under evaluation.

VEGA 1/1273/04 (Bruňáková): The time-course of expression of dbat and dbtnbt genes involved in later steps of paclitaxel biosynthesis and the intracellular taxane accumulation were studied thorough a 64-day culture interval of Taxus baccata callus cultures. The expression profile of these genes was slightly different and varied within the subculture. The highest level of dbat expression was detected 24 hours after inoculation followed by a decrease in both cultures. Although the increase in transcriptional activity of both genes positively correlated with callus growth, the intracellular accumulation of paclitaxel varied during subculture with the maximum in stationary or at the end of linear phase.

VEGA 1/2326/05 (Čellárová): Cryobiological study was aimed at optimisation of cryopreservation procedure for Hypericum perforatum by means of a study of phase transition of cryoprotective solutions and application of vitrification method, respectively. Temperature changes within interval of phase transition were measured directly in cooled samples. We have detected increase of temperature by 0.5 to 7.17°C during cooling process within this interval. The data indicate that amount of released heat depends on the rate of cooling.

APVV 20-003704 (Čellárová): Expression of the hyp-1 gene with proposed function in the biosynthesis of hypericin was studied for the first time. Based on our previous results on expression of this gene in Hypericum perforatum L. with the highest detected level of transcript in organs non-producing hypericin (Košuth et al. 2007) we have continued with an aim to clear up the function of this gene by analyses of transcription level in different representatives of the genus Hypericum, producing and not producing hypericin. It was found that level of expression of this gene correlated with biosynthetic ability. The lowest expression levels were detected in taxons where hypericin was under quantification limit.

AV 4/0029/07 (Dudáš): Methodologic aspects of short-time immobilization of sperm cells were resolved for the purposes of intravital diagnosis.

VEGA 1/4320/07 (Dudáš): We have implemented maintenance of transgenic animal colonies in our animal facility and tested histological detection of cleft defects in embryonic tissues.

APVV LPP-0155-06 (Fedoročko): The role of epithelial seam in palate formation. We have identified important teratogenes inhibiting disintegration of the epithelial seam.

VEGA 1/2355/05 (Kassayová): Chemopreventive effects of selected nonsteroidal antiinflammatory drugs – cyclooxy-genase-2 (COX-2) inhibitors were tested in the model of chemically (N-methyl-N-nitrosourea)-induced mammary carcinogenesis in female Sprague-

30

Dawley rats. Nonselective inhibitor of COX-2 activity - diclofenac was administered in drinking water in concentration of 0.01 mg/ 1 ml. Tumor suppresive effects by some basic parameters of mammary carcinogenesis were recorded. The incidence decreased by 12 %, tumor frequency per group decreased by 39 % and per animal decreased by 32 % when compared to the control group. Administration of selective COX-2 activity inhibitor - celecoxib significantly decreased tumor frequency per group (by 54 %), tumor incidence ( by 24 %) and frequency per animal (by 40 %).

VEGA 1/2362/05 (Mock): Within the project we have realized wide study  of soil fauna in the most important surface and cave localities of the  orographic unit Čierna hora Mts. (E Slovakia).Special attention we  have laid on study of these taxonomic groups: Lumbricida, Acarina,  Palpigradida, Isopoda, Chilopoda and Diplopoda. Within the caves also  Araneae, Opiliones, Collembola and Coleoptera were studied. The most diversified communities of soil fauna were detected mainly in forest and forest-steppe habitats on limestone. Among important findings several West Carpathian endemics were identified, some first records from Slovakia (e.g. mite Belba clavigera) or new for science (millipedes Mecogonopodium carpathicum, Ochogona sp., springtail Neelus sp.).

Selected Results

6RP/DeSANNS-020133 (Zeleňák): New nanoporous sorbents, for selective and reversible sorption of carbon dioxide, were prepared and tested. We have studied the influence of pore size and surface basicity of the sorbents on sorption capacity. The lower limit for pore size of nanoprous silica to be used in preparation of efficient amine-based sorbents is approximately 3,5 nm. Below this size the active sites inside the pores are inaccessible for CO2 molecules due to a limited rate of their penetration to the pores. The molecular sieves with larger pores (7nm) possess higher sorption capacity. The surface basicity is the other factor influencing the sorption capacity.

APVV RPEU-0027-06 (Zeleňák): We investigated influence of amine concentration on mesostructure development in amine modified molecular sieves using SAXS and HRTEM measurements. Hexagonal mesostructure was preserved up to 10 wt.% of amine. The transition to lamellar phase was observed at higher concentration of amine.In the study of metal-organic frameworks (MOFs), several novel 2D complexes with pyrazine or azo-bis(pyridine) were prepared using hydrothermal methods and structurally characterized by single crystal X-ray diffraction. The geometry of the ligands and crystal structure of the complexes were influenced by temperature and pressure used in the hydrothermal synthesis.

APVV-20-038405 (Gonda): The microwave-assisted thermal aza-Claisen rearrangement of allylic imidates and thiocyanates to the corresponding amides and isothiocyanates was investigated. Significant accelerations of the rearrangement of allylic imidates to amides and of allylic thiocyanates to isothiocyanates in comparison with standard thermal reactions was observed. The acceleration of the rearrangement of allylic imidates to amides (8–30-fold) and of allylic thiocyanates to isothiocyanates (24–80-fold) in comparison with thermal reactions carried out at the reflux temperature of the solvent has been described.

APVV-0514-06 (Kutschy): A series of 2-aryl amino analogs of 1-methoxyspirobrassinol methyl ether was synthesized by application of the spirocyclization strategy. Corresponding diastereoisomers were separated by column chromatography and their structure determined by NMR spectroscopy. The obtained substances were tested on their antiproliferative activity against cancer cell lines Jurkat, MCF7, MDA, HeLa, CEM and A-549. Among the most active substances are trans-isomer of 2-(3,4-dichloro)phenylamino analogue (IC50 = 20,7 – 22,6 μmol ´ l-1) and cis-isomer of 4-methylphenylamino analogue of 1-methoxyspirobrassinol methyl ether, which is selectively effective against leukemic line Jurkat (IC50 = 6,6 μmol ´ l-1), whereas against the other studied cell lines it exhibits significantly lower activity (IC50 = 64,7 - >100 μmol ´ l-1).

APVT-20006604 (Walko): New resveratrol derivatives containing the Schiff base moiety and differing in the position of the hydroxy groups were synthesized. Interaction of this potentially cytotoxic derivatives with the DNA was studied. It was observed that they have a high afinity for the DNA as well as they act as an efficient infibitor of the DNA topoisomerase I. Now, the cytotoxicity of those new derivatives is under investigation.

VEGA 1/3550/06 (Černák): Within our continuous study of magneto-structural correlations we have prepared and structurally characterized new bimetallic compounds based on cyano and N-donor ligands. Cu(NH3)2Ag2(CN)4 exhibits 2D crystal structure with antiferrodistortive

43

arrangement of octahedral around Cu(II) atoms; as a consequence the system exhibits magnetically 1D character due to magnetic interactions mediated by hydrogen bonds. Hydrogen bonds play also an important role in enhancing the magnetic dimensionality of Cu(bmen)2Pd(CN)4 to 2D with regard to 1D character of the crystal structure. From the systems Cd(II)/Zn(II)–aepn–[Ni(CN)4]2- were isolated ionic compounds [M(aepn)2][Fe(CN)6].H2O as well as compounds exhibiting formula M(aepn)Ni(CN)4 with polymeric structure. As a by-product of the synthetic procedures a salt [NH4][Et4N]2{[Fe(CN)6]}.3H2O was prepared and structurally characterized.

VEGA 1/2474/05 (Györyová ): New methods of synthesis of zinc(II) complexes with bioactive ligands were developed with the aim to study their physicochemical properties and biological activity. Prepared compounds were characterised by elemental analysis, spectroscopic and thermal methods of analysis and structural determination. The mechanism of thermal decomposition of prepared compounds was investigated. The correlation between spectral, thermal and structural properties of complexes was explained. Microbiological studies confirmed strong antimicrobial and antioxidative effect of prepared complexes. The compound with the highest biological activity does not cause gene mutation. In vivo biological experiments on animals indicated antibacterial properties of zinc.

VEGA 1/3557/06 (Martinková): The microwave-assisted thermal aza-Claisen rearrangement of allylic imidates and thiocyanates to the corresponding amides and isothiocyanates was investigated. Significant acceleration of the rearrangement of allylic imidates to amides and of allylic thiocyanates to isothicyanates in comparison with standard thermal reactions was observed. A novel synthetic approach to β-D-C-mannosyl-(R)- a (S)-alanines was investigated. The key C-N bond formation was effected through the aza-Claisen rearrangement of allylic thiocyanate induced by the microwaves and also realized at the standard thermal conditions.

VEGA 1/3553/06 (Kutschy): Stereoselective synthesis of indole phytoalexin (R)-(+)-1-methoxyspirobrassinin and its unnatural (S)-(-)-enantiomer was achieved by spirocyclization of 1-methoxybrassinin in the presence of (+)- and (-)-menthol and subsequent oxidation of the obtained menthyl ethers. Methanolysis of menthyl ethers in the presence of TFA afforded (2R,3R)-(-)-1-methoxyspirobrassinol methyl ether as well its unnatural (2S,3S)-, (2R,3S)- and (2S,3R)-isomers.

VEGA 1/2118/05 (Oriňáková): The galvanostatic deposition of binary Ni–Co coating onto iron micro-particles was achieved in fluidised bed arrangement. The effect of anode material on the composition of coating layer as well on the distribution of coating components on the surface and across the coated particle was investigated. Regarding the thin coating layer the anomalous behaviour was not observed. The overall content of Ni in binary deposit was always higher than that of Co. However, the Co fraction was greater when the stainless steel anode was used [1]. In the course of electrolytic deposition of Ni-Co coating on graphite electrode it was found that increasing pH value increased the rate of deposition and the content of cobalt in the binary deposit.

DAAD 16/2005 (Oriňáková): Iron powder microparticles were coated with a poly(methyl methacrylate) (PMMA) film by electropolymerization in a fluidised bed reactor. Polymeric PMMA coatings prepared at different experimental conditions were characterised with pyrolysis gas chromatography (Py-GC) fingerprinting as well as time-of-flight secondary ion mass spectrometry (TOF-SIMS). Results confirmed that PMMA coating on the iron powder

44

microparticle surface formed an incoherent and inhomogeneous film. The optimal conditions for preparation of PMMA coating onto Fe particles by electrochemical polymerisation in fluidised bed were specified.

VEGA 1/2470/05 (Potočňák): We have studied an antibacterial and antifungal activity of 9 prepared [Cu(L)2N(CN)2]Y compounds against medicinally imported bacteria (Enterococcus faecalis, Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli) and fungi (Candida spp.). Their antiproliferative activity against L1210 leukemia has been tested, too. Most of the tested compounds expressed increased activity against bacteria and yeasts. Interestingly, the most effective compounds possess also a significant activity against lymphoblastoic leukemic cell line L1210. The most effective compounds are [Cu(phen)2N(CN)2]Y (Y = PF6, BF4 a CF3SO3) and [Cu(mbpy)2N(CN)2]PF6, which inhibit the growth of leukemic cells by 92-96 percent at 10 mM concentrations.

VEGA 1/1274/04 (Podhradský): DNA supercoiling, temperature, the presence of divalent ions and intercalators have cooperative influence on the formation and stability of irregular structural motifs in DNA, e.g. DNA cruciform. The result is possible to extrapolate also for chromosomal DNAs. The coincidence between the cytotoxic concentrations of intercalating agents and the concentrations that modulate cruciform extrusion in vitro is interesting but correlative. Overall, we provide new and interesting insights into the potential role of cruciform structures in biology and, by extrapolation, in cancer therapy.

VEGA 1/1272/04 (Tomášková): We have shown that destabilization effect of polyanions on basic proteins correlates both with isoelectric points of proteins and hydrophobicity of polyanions. This effect, reminding chaperone action, is probably the reason of polyanions increased efficiency of protein refolding. Based on comparison of effect of anions and polyanions it follows that an anion cooperativity in polyanions is the reason of their significant effect on protein stability. Cytochrom c as a typical globular basic protein in a complex with polyanions in slightly acidic environment (pH~5-6) achieves molten globule-like state (MG) that differs by its properties from a „typical“ MG state.

VEGA 1/4459/07 (Walko): New derivatives of the diarylethene photochromic switches were succesfully synthesized. The method used is enviromentally friendly and is based on the solventless reaction. This method also allows to incorporate additional moiety into a diarylethene backbone, a property usefull in construction of molecular devices. However, the method requires further optimization since the yields are not optimal.

KEGA 3/3004/05 (Ganajová): The important results of this project were:1. The formation of the informational - communication chemical - environmental

laboratory (IKCHEL) for selected problems of the topic constant sustainable development in the education of the teachers of Chemistry and Biology.

2. The formation and verification of the monitoring suitcase for fast simple analysis of parameters of, water, soil, air and foodstuffs.

3. The establishment of the chemical – environmental laboratory with the mobile analytical instruments Photometer MultiDirect, RQflex 10 System.

MVTS 9 a APVV SK-CZ 77 – 81 (Vargová): Azamacrocyclic Zn-cyclen complex forms „gauche“ conformationsof five membered chelate rings. Zn-cyclen complex forms ternary complex species with aminoacids glycine and alanine. Nonprotonated ternary species

45

[ZnLL1]2+ a [ZnLL2]2+ (logK = 4.4 alebo 4.9) were confirmed by 1H NMR spektroscopy and potenciometric titrations in slightly alkaline solution. Disocciation constants of protonated species [ZnL(HL1)]2+ [ZnL(HL2)]2+ are 7.5 resp. 5.6. Protonated complexes were isolated from slightly acid solution in solid state.

Selected Results

VEGA 1/3063/06 (Spišiak): We have continued researching the model microregional structures in the rural areas. The studies were carried out in marginal areas where new approaches like changes in land use and perception of inhabitants on development programmes were applied. Some analyses were presented on foreign conferences in the Czech Republic and Hungary.

VEGA 1/2024/05 (Kulla): In this project almost all partial components of humangeographical research were processed. With respect to inhabitants, the intiguing research on Roma population as well as non-traditional research of population intentions of the young has been done. A phenomenon typical of city development in post-socialistic period-suburbanisation - has been elaborated and main urbanisation zones in the city surroundings were identified. Mapping the productive and non-productive activities in the region was another area of interesting research. Issues such as identification of industrial parks, recreation resorts, agrosubjects both in the city as well as in the city surroundings, changes of functional use of city centre are among the most valuable.

VEGA 1/3062/06 (Hochmuth): The principal outcome of the application part was an ongoing implementation of historical and current knowledge and concepts into the proposal of geographical information database of karst territories in Slovakia. The second phase of the proposal comprises the preparation of synthetical work to be published. We have worked on analogue as well as digital founding maps and systematisation of knowledge in the context of proposal of database, structuring the geographical base and verification of its usage for regionalisation of smaller sample karst territories in Slovakia.

APVV SK - UA 00206– Slovensko -Ukrajina (Hochmuth): In the course of the second year of the project we aimed at practical application of methods used in Slovakia and exploring the socioeconomic phenomena on Ukraine border. Considering the evaluation of travel and tourism forms, new Ukrainian methodology that has not been used in Slovakia yet, was applied.

Selected Results

Grant VEGA 1/3128/06 (Geffert): We have obtained new relationship between the sizes of two-way finite automata accepting a language and its complement. In the deterministic case, for a given automaton (2dfa) with n states, we build an automaton accepting the complement with at most 4n states. For the nondeterministic case, using a variant of inductive counting, we show that the complement of a unary language, accepted by an n-state two-way automaton (2nfa), can be accepted by an O(n^8)-state 2nfa. This allows the simulation of unary 2nfa’s by probabilistic Las Vegas two-way automata, still using only O(n^8) states.

VEGA 1/3129/06 (Vojtáš): We proposed a model of a middleware system enabling personalized web search for users with different preferences. We integrate both inductive and deductive tasks to find user preferences and consequently best objects. The model is based on modeling preferences by fuzzy sets and fuzzy logic. We present the model-theoretic semantic for fuzzy description logic f-EL which is the motivation of creating a model for fuzzy RDF. Our model was experimentally implemented and integration was tested.

VEGA 1/4003/07 (Török): We derived a new representation of polynomials based on reference points. We also generalized the r-point transformation for functions of two variables with 2x2 reference points and derived the form of IZA surfaces for local approximation of 3D data. Based on IZA polynomials we suggested new local models with r reference points, r=2-4, and proved that the recursive estimation of the local model is consistent. Due to an appropriate localization of the reference points we succeeded to grant the smoothness of the neighboring approximants without solving the classical system of spline equations.

Selected Results

APVT-20-004104 (Jendroľ): In 1955 Kotzig proved that every 3-connected planar graph contains an edge with degree sum of its endvertices at most 13. This theorem is strengthened for planar graphs of minimum degree 3 in J.Harant, S. Jendroľ [Graphs Combin. 23 (2007), 529-543] where the existence of a star K1,r in every planar graph G of minimum degree 3 is proved such that the central vertex of K1,r has in G degree r, 3 ≤ r ≤ 5, and r - 2 leaves of K1,r

have in G degrees from a certain small list. By this paper are, except for the Kotzig statement, strengthened also several recently published theorems.

VEGA 1/3002/06 (Bukovský): The equivalence of two recently studied properties of the topological space of continuous real functions with topology of pointwise convergence has been shown (QN=(α1), one implication was already known). That enabled to apply some consistency results to unsolved problems connected with so called Scheepers hypothesis (wQN=S1(Γ,Γ)), e.g. to show that this hypothesis is undecidable in the set theory.

67

VEGA 1/3003/06 (Studenovská): In J. Herchl, D. Jakubíková-Studenovská [Soft Computing 11 (2007), 1107-1112] it has been proved that, in general, a unary algebra with more than one operation is not globally determined. In D. Jakubíková-Studenovská, J. Pócs [Czechoslovak Math. J. 57(132) (2007), 975-986] it has been proved that Retract Theorem is valid for all monounary algebras. There have been found conditions of existence and a constructive description of a retract extension of one partial monounary algebra by another one [D. Jakubíková-Studenovská, Selected questions of algebra, Collection of papers dedicated to the memory of N.Ya. Medvedev, (2007), 242-253]. Properties of a Cantor extension of an Archimedean lattice ordered group have been investigated.

VEGA 1/3004/06 (Jendroľ): An n-vertex tree T is arbitrarily vertex decomposable if for any sequence τ of positive integers adding up to n there is a sequence of vertex disjoint subtrees of T with orders given by τ.In the paper M.Horňák, Zs. Tuza, M. Woźniak [Discrete Appl. Math. 155 (2007), 1420-1429] there have been completely characterised on-line arbitrarily vertex decomposable trees. Necessary and sufficient conditions for the existence of G(5,n)-fulleroids having 5-gonal and n-gonal faces only and the group of automorphism isomorphic to a given group have been determined for all possible groups.

VEGA 1/3005/06 (Ohriska): In the study of noncanonical nonlinear differential equations of the third order with quasiderivatives there have been obtained comparison theorems on property A between linear and nonlinear equations. Using these results integral criteria for property A for nonlinear equations have been found. In the study of neutral differential equations there have been obtained sufficient conditions for bounded solutions to be oscillatory which generalise some known results for differential equations without neutral term.

KEGA 3/3007/05 (Šveda): Methodology and recommendation for creation and realisation of e-learning courses have been worked out. General schemes for realisation of cognitive process in e-learning courses have been created with the emphasis on active work with information and utilisation of feedback during teaching process. Some topics from the educational content have been didactically developed.

Selected Results

VEGA 1/3027/06 (Orendáčová): Experimental study of spin relaxation in dipolar spin ice Dy2Ti2O7 has been performed. The obtained results suggest dominant influence of releasing residual entropy by external magnetic field at temperatures lower than 1 K. The lowest temperature obtainable by adiabatic demagnetization of spin ice seems to be nominally 0.3 K due to dynamic crossover in magnetic field induced temperature response. The analysis of temperature dependence of relaxation time indicates Orbach relaxation process. The obtained results did not confirm the existence of quantum tunneling in ‚frozen‘ diploar spin ice.

APVV 005204 (Feher): The specific heat in the temperature region of 100 mK–300 K and in magnetic fields up to 9 T, as well as the susceptibility from 2 to 300 K have been measured in the polycrystalline layered NaxCoO2 (x = 0.65, 0.70, and 0.75) oxides. Analysis of the obtained data gives evidence of anomalous metallic behavior of non-Fermi liquid character. Closer inspection indicates low-lying quantum states resembling Griffiths phases. The underlaying microscopic mechanism is likely related to the mesoscopic phase separation, i.e. the coexistence of partially ordered magnetic regions with Fermi liquid electrons.

APVV-20-007804 (Varga): The domain wall dynamics in thin magnetic wires has been studied in order to find the crucial parameters that govern the maximum velocity of the domain wall. It was found that it is the low anisotropy together with the presence of two perpendicular anisotropies, which is responsible for fast domain wall. The hypotesis was confirmed by the measurement on different magnetic wires. Very fast domain walls have been observed reaching the velocity that exceeded the sound velocity, in the case of microwires with very low anisotropy even 4 times.

VEGA 1/3035/06 (Varga): The domain structure and magnetization processes of amorphous and nanocrystalline FeNiMoB based microwires have been studied. These microwires show magnetic softening after devitrification (in contrary to the FINEMET- based microwires). The anomalous increase of the switching field at low frequencies was explained by the structural relaxation induced by magnetic field.

82

VEGA 1/4020/07 (Kollár): In order to investigate ac magnetic properties of FeNi bulk material, in the form of a cylinder, prepared by hot compaction of the powder the hole with diameter is 5 mm were drilled using spark plasma erosion. The losses were obtained from the ac hysteresis loops traced by an ac hysteresisgraph in the frequency range 100 Hz - 3 kHz at maximum magnetic induction of 0.2 T Annealing at 1000 ◦C reduces the loss, due to the relaxation of internal stresses induced by milling and compaction.

APVV-20-008404 (Kollár): Bulk metallic Co-based samples with different contents of Fe-based Vitroperm-type alloys were successfully synthesized by consolidating the proportioned mixtures of amorphous Co-based and amorphous or nanocrystalline Fe-based powders. For the studied alloys, it was found that the addition of nanocrystalline or amorphous FeCuNbMoSiB powder to amorphous CoFeZrB powder caused a decrease of the magnetostriction of the resultant bulk samples, while the coercivity shows an opposite behavior. The high coercivity may be mainly due to the defects and internal stresses created by milling and consolidation.

Hasylab projekt II-20060031 EC The nanocrystallization of amorphous Co-Fe-Zr-B alloys obtained by melt spinning was followed in detail using in-situ synchrotron radiation diffraction experiments. Both thermal and mechanically induced crystallization processes were investigated. We could evidence the one-step crystallization into a nanoscale mixture of bcc-Co(Fe) and ZrCo3B2 phases at onset crystallization temperatures close to 620oC and the decrease of the exothermal signal with longer milling times. The use of X-ray diffraction line profile analysis allowed us to minitor not only the temperature/time evolution of the average crystallite sizes and microstrains, but also the global microstructural changes of the alloy specimens.

VEGA 1/40009/07 (Sovák): The influence of vanadium content on the magnetic and structural properties of nanocrystalline Finemet-based alloys was investigated. It was confirmed that vanadium influences the creation of nanocrystalline phase and magnetic properties. On the basis of X-ray absorption spectroscopy was performed the analysis of the both nanocrystalline and amorphous state.

VEGA 1/4010/07 (Martinská): The data on the tensor Ayy, Axx, Axz and vector Ay analyzing powers in the dd ® 3 Hen reaction at Td= 270 MeV in the angular range 0° - 110° in the c.m. were obtained. The observed negative sign of the tensor analyzing powers Ayy, Axx and Axz

at smalll angles clearly demonstrate the sensitivity to the ratio of the D- and S- wave component of the 3He wave functions. However, the one-nucleon exchange calculations by using the standard 3He wave functions have failed to reproduce the strong variation of the tensor analyzing powers as a function of the angle in c.m.

VEGA 1/2007/05 (Vokál): Fragmentation of light relativistic stable and radioactive nuclei at energies around few GeV per nucleon have been measured in the frame of Becquerel experiment in collaboration with JINR Dubna. The new results on dissociation of 7Be, 8B, 9Be, 11B, 14N and other light nuclei have been obtained. The new experimental results on emission of different types of secondary charged particles in inelastic interactions of Kr and Au nuclei with nuclei in photoemulsion detector at primary nucleus energies 0.95 and 10.6 GeV per nucleon have been obtained. The analysis of dependence of these characteristics on collision centrality and also the comparison with the results from the calculations in the frame of Dubna cascade-evaporation model of nucleus-nucleus interaction has been made.

83

APVV-20-011704 (Vokál): Scaling properties of the strange baryons and mesons production along with the behaviour of elliptic flow of the strange and non-strange particles produced in ultrarelativistic Au+Au collisions imply a formation of extremely dense and hot nuclear matter with partonic collectivity which furthermore reached thermal equilibrium, including strange quarks. Its behaviour during subsequent expansion and hadronization is consistent with the scenario of quark recombination or coalescence.

VEGA SAV 2/6192/26 (Urbán): Transverse mass spectra and Hanbury-Brown and Twiss correlation functions of negatively charged hadrons, which are predominantly pions, were studied at 40 A GeV/c beam momentum. Based on these data the collision dynamics and the spacetime extent of the system at the thermal freeze-out were examined over a centrality region corresponding to the most central events giving 53% of the Pb-Pb inelastic cross section. Comparison with freeze-out conditions of strange particles and HBT results from other experiments were discussed.

VEGA 1/2009/05 (Bobák):We have proposed a spin valve suitable for a new class of spintronic device which can operate as a current-driven nano-oscilator of microwaves in zero magnetic field.

LPP-0107-06 (Jaščur): It has been found exactly that the decorated square lattice with two different kinds of decorating spins on horizontal and vertical bonds displays a very peculiar critical behavior similar to the effectively quasi-one-dimensional spin system.

VEGA 2/7011/7 (Gális): The most prominent outburst activity over the past 12 years was detected and studies for symbiotic system AG Dra. Object was very active during whole this period whereby its activity was modulated by the pulsations of the cool giant in this system. The flickering activity during the recent outburst of recurrent nova RS Oph was studied and the basic physical parameters of this nova were obtained using own long-term photometric material. New variable star GSC00008-00901 was discovered on the archive CCD images. The observations led to conclusion, that star is an eclipsing binary and its basic parameters were determined. Analysis of photometric and spectroscopic observations of an eclipsing binary DV Psc and V456 Cyg was performed, masses and luminosities of the components were determined and migration of spots on a surface of the components was studied.

KEGA 3/4320/06 (Hanč): We have finished a pilot research of students’ knowledge using FCI test in classical-teaching-methods environment at university and high school level. We have created pedagogical materials for teachers which will apply Peer instruction and Interactive lecture demonstrations. After a study stay we gained a strong feedback and own experience with using PI and ILD directly from originators of the method.

KEGA 3/4321/06 (Kireš): We created and evaluated the e-learning courses for Physics Olympiad categories C,D support. We focused the innovation of the collection of the solved physical problems on student’s conceptual understanding of the selected phenomenon.

APVV, LPP-0192-06 (Kireš): We created and realized the set of popularization activities for basic and secondary school students. E-learning support through web server was established as a platform for systematic teachers and students information about our own activities for them.

KEGA 3/5272/07 (Degro): Analyze of pupils environmental attitudes shows, that pupils are willing to participate on the protection and creation of environment, if adults do for it good conditions. Published teaching materials: Environmental Education in Physics Teaching (methodical guide) and Selected Chapters of Environmental Physics, Part 1.

KEGA 3/3008/05 (Ješková): Improving and updating the physics teaching at high school with the help of the use of information and communication technologies emphasizing the future teachers´ education has brought the following outcome to the education in physics: Set of computer-aided activities available on the web (http.//physedu.science.upjs.sk) and ־

CD ROM. Creation of the course Computer aided school physical experiment in the Moodle system ־

with the distant learning support.

APVV-20-036104 (Miškovský): A special role of the LDL receptors for Hyp delivery to U-87 MG cells in the presence of LDL particles was revealed by the substantial increase of Hyp uptake in the situation, when the number of LDL receptors on the cell surface was elevated. Moreover, the colocalization experiments showed the lysosomal localization of Hyp following the uptake and that the concentration of Hyp in these organelles was enhanced in the cells with elevated number of LDL receptors when the incubation medium contained LDL. These facts can significantly contribute to the improvement of the selectivity of accumulation of photosensitizers to cancer cells and consequently lead to the higher effectivity of photodynamic therapy of cancer. Time resolved phosphorescence of Hyp embedded in LDL as well as time course of singlet oxygen creation and annihilation after illumination of Hyp/LDL complex with visible light was thoroughly studied.

VEGA 1/4019/07 (Uličný): We introduced simple and extensible quantitative model of caspase activation process as a point of convergence of both intracellular and extracellular stimulation.In this model, caspases 8 and 9 represent all initiator, and caspase 3 represents all effector caspases. The model also includes interactions of apoptosome complex as the key player in intracelular apoptotic pathway. Activity of effector caspases is controlled by effective representant of IAP protein family. The effective BAR inhibitor, was found as crucial regulator of sensitivity of modeled system. The model is based on experimental data from HeLa cells and correctly predicts most characteristic dynamical features of caspase cascade.

VEGA 1/4021/07 (Brutovský): We have developed the methodology for the simulation of circular growth with a priori defined properties of the border (quantified by the fractal dimension) and the growth rate. The methodology has been applied to test the hypothesis about the growth of multicellular tumor spheroids and the possible dependence of the therapy efficiency on the fractal dimension of the tumor spheroids border.
