Leaf antomy of the plants growing in saline soils
Ivanova N.A., Muzychko L.M.
Abstract
Distinctive features of leaf anatomy of plants growing in saline soils of Northern Kazakhstan, mainly in Kostanay Oblast, were studied. According to Y.V.Gamaley’s classification, plants of different skleromorphic leaf structures prevail in soils with low and medium soil content, whereas high salinity soils are dominated by succulent plants

Species composition and ecological characteristics of planktonic cyanobacteria in the Vakh river
Skorobogatova O.N., Naumenko Y.V.
Abstract
The work describes the results obtained from the study of planktonic cyanobacteriae of the Vakh river. Thirty two taxons have been identified of 13 genera, 10 families, 2 classes of Cyanophyta division. Twenty nine of them were identified for the first time in the Vakh river. Anabaena spiroides species hasn’t been found in the studied samples. Taxonomic composistion and ecological characteristics of planktnonic cyanobacteriae found in the Vakh river are considered

Switching sympathetic cervical ganglion off for indication of cardiac function of rats
Chiglincev V.M.
Abstract
For the first time the research has been carried out to measure heart rate dynamics and stroke volume of sympathectomized infant rats from 21st till 120 days of age under one stage bilateral stimulation of vagus nerves and obsidian-induced stimulation of vagus nerves. It is revealed that the electrical stimulation of both vagus nerves causes a decrease in the heart rate and stroke volume in sympathectomized rats of all age groups examined. After one stage bilateral stimulation of vagus nerves sympathectomized rats display no heart rate increase at 28 days of age. Moreover, the heart rate reduction of sympathectomized rats under the stimulation of the vagus nerves was minimal as compared to intact animals

Climate frocing role of ocean currents
Kozina O.V., Dugin V.S.
Abstract
On the example of the Gulf Stream, the influence of currents on the climate of northern continents is considered. Climatic norm for the temperature of parallels corresponding to latitudes of the Gulf Stream has been identified. The influence of the Gulf Stream not only on coastal areas of North America and Eurasia, but also on the territories of Europe and Asia distant-located from the ocean has been analyzed

Theoretical & methodological foundations of territorial organization of society
Sokolov S.N.
Abstract
The article considers different approaches to the definition of the territorial organization of society, stating that various authors have developed theories of cycles. It provides analysis of the resource cycles and energy producing cycles. The author introduces the concept of market cycles of economy. In such a cycle information is used as the primary resoure instead of natural raw materials or energy. This cycle in the best way characterizes production and non-production processes taking place in a particular area

Formation of the sustem of settlement of Transurals
Yasybaeva R.S.
Abstract
Historic and geographical factors played a big role in the development of a system of settlements. They are primarily connected to geographical location of every region withing Bashkortostan’s Transurals. It should be noted that towns appeared to become centres of non-agricultural activities, trade and commerce. Therefore the great importance was placed on natural resources and trade routes

Functional potency and number of microorganisms in oil-contaminated soils
Usacheva Y.N.
Abstract
The work is devoted to analysis of oil-contaminated soils according to lysis of azotobacter colonies, amino acids deamination and microorganisms’ responces to oxygen. The research indicated that oil contamination increases lysis of azotobacter colonies, amino acids deamination, decreases growth of microorganism and their intensity in environment. The methods used during the research could be employed for analysis of oil-contaminated soils

The analysis of correlation between survival rate & fertility of Ceriodaphnia affmis and chemical composition of water
Aleksandrova V.V.
Abstract
The proximate and multivariate correlation analysis between the results of biotesting and tests of water chemical composition is carried out. Survival rate and fertility of Ceriodaphnia аffinis were biotested. The correlation between survival rate, fertility of Ceriodaphnia affinis and water chemical composition is described as both positive and negative.

Features of the pigment system of Lemna minor when exposed to copper ions
Storchak T.V., Grischechkina A.A.
Abstract
The research concerned the influence of copper ions on the content of pigments in the leaves of Lemna minor , which shall be used for biotesting of the polluted water of the surface impoundments. The studies were carried out in the model experiments. The plant Lemna minor was kept in the solution of copper sulfate having different concentrations. The amount of pigments was determined using the spectrophotometric method. The content of chlorophylls and total number of carotenoids was determined by the Lichtentaler formula. The copper ion has a toxic effect on the Lemna minor plants, which influences the growth and the content of pigments; the photosynthesis processes are suppressed.
