The technology of utilization of drilling waste in the framework of pilot tests at an oil field is considered. The technology is based on a physicochemical method of disposal of drilling waste by introducing natural environmentally friendly components aimed at improving the water-physical and chemical properties of drilling waste. The basic technological scheme of utilization of drilling waste by pitless drilling is presented. The man-made soil obtained in the process of utilization of drilling waste is suitable for reclamation of adjacent (adjoining) industrial and auxiliary infrastructure, disturbed lands of temporary and permanent allotment of oil fields. The hydrogen index in the technogenic soil corresponded to the alkaline reaction of the medium and amounted to 8.8 pH. The content of oil products was at the level of 956 mg/kg. In terms of salinity, the technogenic soil was classified as non-saline soil (<0.5%).

Naftalan oil is known to be used in a treatment of various deseases. The unique medicinal effect is caused by the special chemical nature, due to this oil is differ from the industrial one. The actual problem of today is to study physical and chemical properties and chemical composition of Naftalan oil from various expluatation levels for the development of scientific bases of ecological monitoring of medicinal oil, and for the solution of the practical tasks on its standardization. The paper discusses the study on physical and chemical properties and chemical composition of the oils from the various levels of the top part of Naftalan field and the peculiarities of its biological effect.The tasks are as: a determination of physical and chemical properties, component and group hydrocarbon composition of oil in working wells of three exploitation levels (the first, marly, the second – sandy) of the top department of the Maikop suite of Naftalan oil field; a comparative study on structure-group composition of saturated hydrocarbons isolated from different on the properties samples of Naftalan oil to find their “working start”. As a result of the studies the influence of vertical differentiation was shown to effect sufficiently on fraction and component composition of Naftalan oil. The peculiarities of area distribution of a deposit are associated with changes in properties and composition of a fold structure and presence of the bed water-oil contact. A stability of oil of the first and marl levels and changes in properties of oil of the second sandy level effected by the stretching levels of the commercial oil are shown by the comparison of the results of the systematical analysis of the oil from the working wells of the top department of the oil field carrying out for 10 years. A difference in physical and chemical properties of oils was found to be caused by the peculiarities of structure-group composition of saturated components.Forcitation:Adigozalova V.A., Polyakova L.P.

In connection with the spectrophotometric study of population-type characteristics of various kinds of stars, a statistical analysis of kinematical and distribution parameters of the same stars is performed at the Toruń Observatory. This has a twofold purpose: first, to provide a practical guide in selecting stars for observing programmes, second, to contribute to the understanding of relations existing between the physical and chemical properties of stars and their kinematics and distribution in the Galaxy.

Organic farming is one of the management strategies that improve productivity of marginal uplands. The study aimed to: (1) evaluate effects of various organic-based fertilizers on the growth and yield of corn; (2) determine the appropriate combination for optimum yield; and (3) assess changes on the soil physical and chemical properties. Experiment was laid out in Randomized Complete Block Design, with 3 replications and 7 treatments, namely; T0=(0-0-0); T1=1t ha-1 Evans + 45-30-30kg N, P2O5, K2O ha-1; T2=t ha-1 Wellgrow + 45-30-30kg N, P2O5, K2O ha-1; T3=15t ha-1 chicken dung; T4=10t ha-1 chicken dung + 45-30-30kg N, P2O5, K2O ha-1; T5=15t ha-1 Vermicast; and T6=10t ha-1 Vermicast + 45-30-30kg N, P2O5, K2O ha-1. Application of organic-based fertilizers with or without inorganic fertilizers promoted growth of corn than the control. But due to high infestation of corn silk beetle(Monolepta bifasciata Horns), its grain yield was greatly affected. In the second cropping, except for Evans, any of these fertilizers applied alone or combined with 45-30-30kg N, P2O5, K2O ha-1 appeared appropriate in increasing corn earyield. Soil physical and chemical properties changed with addition of organic fertilizers. While bulk density decreased irrespective of treatments, pH, total N, available P and exchangeable K generally increased more with chicken dung application.
