AGE-RELATED CHANGES OF MORPHOLOGICAL PARAMETERS OF PIKE PERCH THE FIRST GENERATION WHEN GROWN IN RAS [№ 12 ' 2016] In commercial breeding of fish pay special attention to its physiological state, which is estimated based on the account of morphological and physiological indicators. The aim was to assess the conditions of cultivation and to determine the value of the indices of internal organs walleye the first generation, for the first time introduced to the process of growing mode in the ultrasound. The material for the research was collected during the research work for three years from 2007 to 2009 served as objects of fingerlings, yearlings and two-year walleye. The first generation was obtained from wild walleye eggs and grown under regulated temperature. At the age of 76 days the fry reach an average sample of 1 g and were transported to the ILC LLC “Aqua”, where they put in pools of pilot RAS. As a result of the research within three years could determine the indexes of internal organs from fingerlings, yearlings and two-year walleye. All of the fish examined, regardless of the age of the maximum values of the relative mass were observed in the index of the gills, and the minimum in the spleen index. In the study of the internal organs of juvenile walleye, marked a change of color and structure of the liver. It was noticeable increase in her and change the color to pale sand, which is obviously connected with the feed quality. As a result of analysis of the feed was carried out and recommendations for optimization of feeding walleye. Comparing the results, age dynamics of the relative mass of internal organs was found. In the analysis of the data was possible to establish certain regularities in the changes of the studied first domesticated in RAS walleye the first generation, which was the basis for further research in the direction of establishing the status of walleye morphophysiological under RAS.

OUTLOOK RECYCLING SPENT TYPE ZEOLITE NAX ORENBURG GAS CHEMICAL COMPLEX [№ 10 ' 2015] NaH type zeolites used in industry for drying and deep fine purification of gases and liquids, for the separation of gaseous and liquid mixtures, separation of a mixture of hydrocarbons in a cryogenic air separation plant. Used zeolites Orenburg gas chemical complex is placed on authorized landfill gas production management and refers to the IV and V classes of hazard. Zeolites are unusable production waste. The paper presents experimental data on the reuse of waste zeolites. Laboratory studies were carried out on the basis of a branch of Gubkin Russian State University of Oil and Gas in Orenburg. A variant of asphalt production with the introduction of the grain portion of these zeolites. On the basis of the experiments selected the optimal component composition of the experimental asphalt. A variant of the use of waste zeolites — putting them in the concrete mix as a placeholder. It was found optimal amount of spent zeolite added to the composition of the resulting samples. A technique for obtaining samples of concrete mixtures and their composition. Determine their strength properties, such as water saturation, swelling, tensile strength, and coefficient of frost-grade asphalt and concrete strength. Depending on the strength of the samples revealed the content of the waste in their composition zeolite the possibility of using zeolites in agriculture. The developed technology allows to relieve the landfill and reduce the environmental burden on the region. Implementation of the proposed technologies in production will be accompanied by extra profit.

Stryapkov INDUSTRIAL TESTS OF THE ZEOLITE SAA-U CARRIED OUT ON THE ETHANE FRACTION CLEANER AT ORENBURG HELIUM PLANT [№ 3 ' 2001] The article cartains a positive experience of the home tzeolit SAA-U use. Industrial tests were carried auf in the Orenburg helium plant. Some practical recommendations on the use and on regeneration, in particular, of tzeolit were given.
