Institute of social-economic problems of Aral sea region, Karakalpak branch of Academy of sciences of Uzbekistan, Nukus
SUMMARY
The paper presents the concept for truth-table software means to simulate composite environmental-meteorological processes. Advantages in the system integration of the models considering features of dynamical systems had been shown. Conceptual system approach to integrated meta-model development allows to avoid eclectic outlines in bioclimatic researches. General theoretical framework allocates an ontological synchronization of functional sub-models. This holistic construction with unified computational procedure is an effective tool for a system analysis of complex geographical objects and feedbacks in environmental climatology.

SUMMARY
Various types of light emission due to recombination: on X-Rays luminescence (XRL), gamma-luminescence (GL), cathode-luminescence (CL), thermo-luminescence (TL) in crystals BaFX (x=c1,y) had been studied. Has been studied temperature affected luminescence intensity and also admixture strength affected recombined luminescence intensity. The analysis identified that the luminescence layers with maximum range 300-340 nm for BaFY crystals and 360-365 nm for BaFCL crystals depends on neutral excitons luminescence having (Vk+ё) form.

SUMMARY
This article observes the case of Schottky. Barrier Diodes Mo-n-n+-GaAs affected by microwave frequency. Has been studied the changes of inter phase interactions in phase Mo-GaAs boundary layers and contact parameters caused by microwave emission. Has been identified that the changes on boundary layers is the result of inner mechanical tensity relax in contacts, caused by microwave emission. The effect of which is the decreased deflection in contact structure. After induced microwave emission the barrier parameters in Gallium arsenide semiconductors having Schottky Barrier Diodes Mo-n-n+-GaAs structure was intensified. It occurs due to stipulated microwave frequency emission on inter phase interactions.

Complex Institute for Natural Scienses of Karakalpak Branch of UzAS, Nukus
SUMMARY
Kinetics of a photocurrent at laser photoionization of СО2 solutions and water in liquid tetramethanesilane was considered. The constants of direct and opposite reactions rate of CO-2:+ H2O U CO-2 (H2O) were determined to be К10 = 3X1010 м-1с-1 and К = 2X105 с-1 at Т=293 К, respectively. The calculated in a such way constant of rate of СО2- ion hydration appears approximately twice less, than for an О2- ion in tetramethanesilane. Also it is shown, that the presence of water increases the time of electron auto detachment from negative ions, that is considered to be connected with the formation of СО2-(Н2О) cluster ions.

SUMMARY
It is shown that in various age working termites as well as in soldiers and winged termites the protein contain in a body is subjected to seasonal fluctuations. In the spring and autumn in all termites, irrespective of age and castes the protein contain is raised, and during the diapauses period (in the winter and summer) is goen down. The increase or fall of the protein contain in the termite body are correlated with their viability.

Biodiversity of a butterfly (Lepidoptera, Cossoidea families) the Khorezm region
Bekchanov X.U.
Urgench state university
SUMMARY
During last decades the biodiversity and natural resources of Uzbekistan undergo considerable depletion. Land use intensification caused extreme anthropic pressure on various species, including butterflies. Strength and range of these species drop down. All these phenomena are result of land reclamation, environment pollution and hunting. Khoresm oasis has unique natural resource due to genesis and spatial isolation of the domain. Butterflies are one of the important component of the ecocenosis.

SUMMARY
The paper investigates dimension, hatching rate and content of polyunsaturated fat acids of cysts of Artemia parthenogenetica from the Aral Sea. Dimension (diameter) was on average 235,5 µm varying from 228 µm to 244 µm. Hatching rate was on average 71,5%, varying from 62,6% to 76,4%. Oleic acid make 30,3% of total fat acids of cysts, linoleic acid – 6.2%, linolenic acid – 6,9% arachidonic acid – 1,5%, eicosapentaenoic acid – 12,8%. So all major parameters of cysts of Aral Artemia completely meet the international standards of quality.

Coldwater aquaculture development in Uzbekistan as a way of rationale using of water resources productivity in the basin of the Aral sea
Juldashov M.A.
Navoi pedagogikal institute
SUMMARY
Goal of the work is choosing of new ways for escalation of fish production in Uzbekistan. Characteristics of natural, primarily and secondary artificial water bodies is given. Fish capturing has no real base under conditions of deeply landlocked and completely stocked basin of the Aral Sea. In addition, local ichthyofauna is poor with commercial species. Aquaculture is presented only by one form – extensive polyculture of carps in earth ponds with low productivity (up to 19 centners/ha). That technology can be optimized, but this is strongly not enough for the country. On the base of water temperature analysis is shown that one of the most promising directions of development is coldwater aquaculture in pre-mountain regions of republic. About 75% of population lives on such areas. Raceways and cage trout culture development is recommended.

Comparison of algoflora of the Andijan water reservoir with other impoundments of Uzbekistan and Central Asia.
Ergasheva Kh.E.
Namangan State University
SUMMARY
Analyses of algae in the Andijan water reservoir in comparison with twelve big water reservoirs of Uzbekistan and Central Asia is given. Algae species compound in the Andijan water reservoir (418 species) is very similar to the Kayrokkum water reservoir (212 species) and Chordara water reservoir (210 species). But Uchkizil pond and Tudakul water reservoir have small common species with the Andijan water reservoir– only 36 and 30 species accordingly. There is lack of species compound similarity in the water objects far outlined from the Andijan water reservoir. Especially low similarity for Tudakul and Kuymazar water reservoirs caused with differences in mineral salts content.
