DEFINITION OF BASIC PARAMETERS ON HEAVY METALS IN ECOLOGICALLY DANGEROUS ZONES ^{[№ 6 ' 2011]}
To determine the basic parameters in multiparameter researches a matrix of research has been constructed. We find the matrix of factor loadings using the principal of components method. Varimax rotation in the space of factors was carried out, the maximum loading by absolute factor was found, and the association of the parameters of factors was identified. Polynomial models were constructed for all parameters of the study. Determination of contribution of the parameters-arguments was realized by constructing models for each option. A comparative analysis of quality of group conditioning with quantitative parameters of conditionality was conducted in this paper.

DETERMINISTIC AND STATISTICAL METHODS FOR PREDICTING THE NATURAL PROCESSES ^{[№ 5 ' 2011]}
We consider the prediction of gender time based on the tidal changes of gravity. The results are given for the prediction models build on the matrix without shift and with shift of time frame for tidal changes in gravity.

DEFINING QUALITY OF GROUP CONDITIONING POLLUTION OF ATMOSPHERE BY DIVISIONS NOSTA ^{[№ 4 ' 2011]}
For definition qualitative group conditioning pollution of atmosphere by divisions NOSTA on an initial matrix of research study was conducted factor analysis. Factor analysis has given associations of parameters of research under four factors. According to the factor analysis the parameters which have united in one factor, have one nature of behavior. That is all parameters of pollution the atmospheres which have got to one factor, are caused by the ejections of divisions NOSTA which have got to this factor.

QUANTITIES ASSESSMENT OF DEPENDENCE FROM ATMOSPHERIC POLLUTION ^{[№ 1 ' 2011]}
To quantify the conditioning between the parameters of the study we build up the regression models, and based on them we determined the contributions of the argument parameters to these models. These argument parameters contributions are the estimate for the quantitative dependence of the parameter in the regression model. Parameters of the study were taken as argument parameters in the regression models. Regression models were built through Brandon method and method of least squares.

THE DETERMINATION OF THE QUALITATIVE PAIRED CONDITIONALITIES OF THE POLLUTION OF THE ATMOSPHERE BY SUBDIVISIONS OF NOSTA ^{[№ 10 ' 2010]}
For determining all forms of the conditionalities of the pollution of the atmosphere by subdivisions of NOSTA the matrix of experiment was built. For determining the qualitative paired conditionalities the correlation analysis on all parameters of a study was realized. According to correlation analysis with the values of the coefficient of pair correlation on the modules large 0,75 we obtained the strong linear connection between two parameters of a study. With the values of the coefficient of pair correlation on the modules greater 0,5 and less than 0,75 — average linear connection between two parameters of a study. And with the values of the coefficient of pair correlation on the modules of less than 0,5 — weak linear connection between two parameters of a study.

AGE MORPHOMETRY OF NASAL MEATUS AS ONE OF THE MAIN ASPECTS WHEN USING PROBES AND CATHETERS IN GOAT-RANCHING PRACTICE ^{[№ 9 ' 2009]}
The article presents morphometric data, characterizing anatomic features of nasal cavity structures, which form nasal meatus – passages for probes and catheters. Data and pictures, given in the article, clearly demonstrate dependency of sizes of used probes and catheters upon morphometric peculiarities of nasal meatus of goats of Orenburg breed.
