TOURIST INFRASTRUCTURE CAPACITY IN ORENBURG REGION ^{[№ 1 ' 2015]}
The article provides an analysis of tourist-infrastructure capacity in Orenburg region. Tourist and infrastructure capacity is considered as one of the components of infrastructure capacity territory including a set of stable functioning institutions, schools, businesses, transport, communications, collective and individual means of accommodation and activities which should cater for tourists. This research is based upon the aggregate of statistical data on cities and districts of Orenburg region. To estimate the total tourist and infrastructure capacity of Orenburg region the following indicators have been analyzed: the specific gravity of paved roads in the length of public roads; the proportion of roads with improved surface in the length of public roads with hard surface; the number of cultural and leisure facilities; the number of places in institutions of culture and leisure; a turnover of catering enterprises; the number of hotels and similar accommodation; the number of rooms in hotels and similar accommodation; the number of overnight stays in hotels and similar accommodation; the number of national parks; the number of objects of cultural heritage. In assessing the tourist-infrastructure capacity of Orenburg region based on the above parameters there has been calculated an integrated coefficient characterizing the level of development of tourist and infrastructure capacity in the towns and districts of the region. On the basis of the data we’ve made a cartogram characterized by the development of tourist and infrastructure capacity in the cities and districts of Orenburg region. The analysis of the coefficients showed the uneven distribution of tourist and infrastructure capacity in the territory of Orenburg region. Orenburg, Orsk, Buzuluk, Sorochinsk, Orenburg and Pervomajskij districts are among the towns and districts with the highest level of tourist and infrastructure capacity. Svetlinskiy and Yasnensky Districts, the towns Yasniy, Abdulino and Sol-Iletsk have relatively low levels of tourism and infrastructure capacity. The analysis of tourist and infrastructure capacity in the article allows to draw conclusions about the reasons for the relatively low development of the tourism industry of Orenburg region and to identify the necessary measures to improve the tourism infrastructure in the regional towns and districts with a high recreational potential.

FORECAST DAYS WITH ZERO VALUES OF THE AVERAGE DAILY AIR TEMPERATURE IN THE HARMONIC MODEL OF TIDAL GRAVITY CHANGE ^{[№ 9 ' 2012]}
Spectral methods by building harmonic models for the average daily rate of acceleration, the third, fourth derivative amendment tidal changes of gravity. By construction, the model is determined by numbers of days with zero values, which are projected numbers of days with zero values of the average daily air temperature.

SPACE-TIME WATER BALANCE STRUCTURE OF THE SOUTH-URAL RIVERS AS THE FOUNDATION TO DEVELOP THE METHODS TO PROVIDE THE HYDROLOGICAL STUDY ^{[№ 2 ' 2005]}
The author characterizes the mechanism of forming and transformation of the water-resources elements in the river Ural, and using the water-balancing method points the changing factor of its time and space structure. Taking Sakmara as an example the author develops specifically regional ways of hydro-resources rating.

INVESTIGATION OF JOINT HYDROLYSIS OF CERIUM (III) WITH FERRUM (III) ^{[№ 1 ' 1999]}
Precipitation composition produced by joint hydrolisis precipitating of cerium(III) with ferrum(III) from sulfate solutions under various pH has been studied. It is found that bond strength of cerium(III) with precipitation is great enough and only ions presented in the solution are recovered with cationite KУ-2х8. The mechanism of coprecipitating included acidic properties of joint ion strengthening and formation of covalent bonds is suggested.
