A problem of pursuit in the controlled systems of elliptic type without mixed derivatives with variable coefficients was considered. The model of the considered system is described by partial differential equations. The players (opponents) control parameters occur on the right-hand side of the equation and are subjected to various constraints. The first player’s goal is to bring the system from one state into another desired state;the second player’s goal is to prevent this from happening. We represent new sufficient conditions for bringing the system from one state into another. The finite-difference method is used to solve this problem.

The electrical conductivity of pure CaTiO3 and that containing 0.5~5.0 mole fraction CuO as dopant were measured in the temperature range 291~773 K. The conductivity values varied as a function of temperature and dopant concentration. The activation energy in the lower temper- ature range depended on the impurity content while in the high temperature range it indicated a value of energy gap width. The infrared absorption spectra in the range of 100~4000 cm-1 revealed the presence of two main bands at 340 and 570 cm-1 which were assigned to Ti06 oc- tahedral normal mode. Bands in the range of 106~270 cm-1 were due to the vibration of anion TiO3-2. Some bands were observed at higher values due to the presence of lattice imperfections. There was a slight shift in band position with increasing dopant concentration which favors the formation of orthorhombic modification.

It is noted that necessity of further increase of accuracy of GPS positioning systems requires de-velopment of more perfect methods to compensate information losses occurred due to residual ionospheric delay by using optimization procedures. According to the conditions of formulated optimization task, the signal/noise ratio in measurements of zenith wet delay depends on the second order ionospheric errors, geographic latitude and day of year. At the same time if we assume that the number of measurements at the fixed geographic site is proportional to geographic latitude and if we accept existence of only two antiphase scenarios for variation of residual ionospheric delay on latitude normed by their specific constant, there should be optimum functional dependence of precipitated water on latitude upon which the quantity of measuring information reaches the maximum. The mathematical grounding of solution of formulated optimization task is given.

Background: Systemic inflammation due to radiation exposure has been identified in a biological system by certain metabolic and behavioral disorders. These anarchies mostly mediated under a regulation of cyclooxygenase 2 (COX2) induced production of an inflammatory mediator prostaglandin E2 (PGE2). Aim: This study was undertaken to investigate the anti-inflammatory impact of brown sea weed extract (BSWE) against induction of COX2/PGE2 inflammatory pathway in gamma-irradiated rats. Rats were orally administrated with BSWE (27 mg/kg body weight/day) for 7 consecutive days before exposure to 8 Gy fractionated gamma radiation (2 Gy × 4;every 3 days). Treatment with BSWE was extended along with and in-between irradiation doses for another 14 successive days. Our data demonstrated that the administration of BSWE to rats exposed to gamma radiation, following the regimen suggested, significantly neutralize the changes induced in the inflammatory molecules COX2, PGE2, tumor necrosis alpha (TNF-α), and nitric oxide (NO). In addition, it adjusted significantly the cellular redox tone via regulation of changes induced in malondialdehyde (MDA) reduced glutathione (Gsh), superoxide dismutase (SOD) catalase (CAT) and xanthine oxidoreductase system (XOR). Credibly, from the results emerged in this study, it could be suggested that BSWE has substantial anti-inflammatory activities and gamma radiation protection capabilities. It is recommended to include BSWE in the treatment strategy of various inflammatory diseases especially cancer as a safe natural anti-inflammatory agent.

It is well-known that according the Dozier’s method, utilization of integral of Planks function in fusion of signals of two different channels of airborne radiometer makes it possible to compute such components of temperature field within one pixel as temperatures of the object and background. In the paper, the generalization of Dozier method is suggested. The suggested generalization of Dozier’s bispectral method named as biparametric method is applicable for static remote objects. In the suggested biparametric method, the measurements are carried out at the moments t1 and t2. It is assumed that the object temperature reaches quantity T(t1) and T(t2) at these moments. On the bases of operational data of scanning infrared radiometer, the square area of one pixel can be calculated in dependence of distance between object and radiometer. This makes it possible to carry out location of static objects from two basis points using serial single wavelengths measurements of radiation emitted by the sub pixel object.

Our expedition have identified location in the central part of Kosovo where were collected a samples （accessions） at coordinates; Sub-Locality SL-1 （N42°34′36″, E21°07′45″）, altitude 574 m, SL-2 （N42°34′29″, E 21°07′45″altitude 591 m and SL-3 （N42°34′30″, E21°07′46″） on altitude 565 m. The aim of present investigation was carried out to study genetic variability of quantitative and qualitative parameters. The populations from SL-2 were characterized of higher significance on seed oil （23.74%） and protein content （16.74%）. The estimation average value of seed protein and oil content was 15.52% and 23.48% respectively. The variability of plant height ranged from 182.33 cm to as much as 200.89 cm, while distinction＇s between them were ＋ 18.56 cm which was a significant higher at P〈0.05 probability level. The SL-3 showed the higher value of hWK （34.6 g）, head per plant （39.33） and head diameter （9.5 cm） but, was characterized significantly lowest on seed protein content （13.99%）. The all traits included in our investigations showed a higher genetic variability with majority of extreme values. The sunflower populations differed significantly in several parameters measured, they have a different genetic and morphological backgrounds. Results from wild sunflower form indicated notable differences in dispersion of important genes for different traits and showed the potential for using in future for breeding program.

The pure spinel phase of Ni0.45Co0.2Zn0.35F2O4 was prepared by coprecipitation method and ceramic method. The nanocomposite [(NCZF)1–x(Na(***))x] (x = 0%, 20%, 40%, 60%, 80%, 100%) was prepared by mixing two phases, Ni0.45Co0.2Zn0.35F2O4 with coprecipitation method [NCZF] and sodium acetylacetonate [Na(***)]. The TEM photographs of the as prepared ferrite samples by coprecipitation method at different ratios of Na(***) show that the crystalline cubic nanoparticles diameter were ranged from 26 - 36 nm and the particle size of Na(***) is greater than NCZF. The same behavior has also confirmed by XRD pat-terns indicating polycrystalline nature of prepared sample. The comparison between the SEM micrographs for NCZF nanoparticles prepared by a) ceramic method and b) co-precipitation method was done to show the effect of preparation condition on the microstructure. IR analysis confirms the composites formation.
