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.

The presence and introduction of new potato cultivars in kosovo has increased the yield per unit area but reduced the cultivation of native potato population. Indigenous potato is linked to specific adaptations to local fanning system and specific agro ecological conditions. This research was conducted in Prishtina region which is located in the kosovo agro ecological region （42°38′97″ latitude and 21°08′45＂ longitude at 574 m.a.s.l ）. Plant material used in this research was 18 potato accessions with different origins. The experimental design was a randomized complete block （RCB） with three replicates, while the plot sizes were 4.20 m^2. All observation and analysis were carried out on 12 plants from each accession. All characters were measured in the field and laboratory at the normal harvest time. Morphological diversity was characterized using standard descriptors. The genetic diversity studies of the investigated potato accessions showed significant genetic variation on 17 physiological and chemical parameters, which could be largely due to that they were of different origins. The genetic diversity of potato cultivars offers a wealth of natural resources from which breeders can select the most desirable genotypes based on their favorable traits.

本文分析了谨慎型消费行为、枯竭型消费行为和畸形结构型消费行为三种非理性消费行为。谨慎型消费行为由旧消费习惯、实用消费观念等因素所导致,可以引起消费不足的问题;枯竭型消费行为由攀比心理、虚荣心理等因素所导致,可以引起产生物价过快上涨的问题;畸形结构型消费行为由偏好刚性、物质欲极强等因素所导致,可以引起社会资源利用效率降低的问题。对中国非理性消费现象进行分析,发现中国居民非理性消费行为符合上述理论解释。

Equipment has been designed and created for experimental simulation of space environment conditions of Geostationary orbit of the Earth. The following conditions are supported in the vacuum chamber having volume of 1.2 cubic meters: Vacuum 10-5 Torr. (1.3 × 10-3 Pa), electron beam with energy up to 8 MeV, temperatures from -150°C to +150°C and solar ultraviolet radiation. The peculiarity of this equipment is the possibility of analyzing complex simultaneous influence of mentioned above 4 factors on the sample and in-situ direct measurement of sample parameters under irradiation which provides almost real conditions. Silicon single crystals used in space environment were tested in the vacuum chamber and new results were received having scientific and applied interest. It was shown, particularly, that the electro-conductivity of silicon samples has higher value at in-situ condition than ex-situ after irradiation.

In nature, cellulose, lignocellulose and lignin are major sources of plant biomass; their recycling is indispensable for global carbon cycle. The major portion of the municipal solid waste consists of lignocellulose. The incineration of organic fraction of municipal solid waste （OFMSW） with high moisture content and low calorific value is not environmentally, techno-commercially viable option for energy recovery. Optimization of biomethanisation process is aim to maximize organic waste stabilization at short digestion period with higher energy recovery. The biomethanisation studies, demonstrate co-digestion of substrates improves CH4 yield due to nutrients balance. Fungi are low sensitive to environment, thrive in acidic environment and produces required multi-enzyme, attach to cell envelope and hydrolyze the substrate for energy recovery. Fermentation of cellulose by the monoculture results in the formation of H2, CO2, formate, acetate, lactate, succinate, and ethanol. In co-cultures with Methanobacterium, H2 and formate reduction indicates it＇s utilized in CH4 production. Engineered co-culture of microorganisms is essential for the heterogeneous complex organic substrate degradation for extraction of unutilized energy fraction of biomass, as potential source of energy.
