Chlorination is the most common, and in fact no alternative method of disinfection using in Baghdad water supply system. Thus there is an urgent need to control the trihalomethanes (THMs) in drinking water. One of the objectives of this study is to investigate the content of THMs in Baghdad water supply network. Studies showed that the substantial amount of THMs formed in water distribution system, THMs content tends to increase with the distance from the starting point coupled with a decrease of residual chlorine concentration. It is observed that in summer total THMs concentration growth rate in water supply network was 1.3-1.4 times higher than in winter as well as total amount of THMs increase by 30 percent in summer. It was found that the concentration of total THMs never exceeded 80 μg/l – the level specified in National Primary Drinking Water Regulations: Disinfectants and Disinfection Byproducts (Stage 1) established by USEPA. However, in summer total THMs concentration in the water always exceeded 40 μg/l – the level set in accordance with Stage 2 of this Rule. The most of total THMs (73-80%) were bromine compounds (CHCl2Br, CHClBr2 and CHBr3). It is shown that the most efficient way to reduce THMs in Baghdad water supply network is to use the chlorine dioxide for chlorination.

his paper presents mathematic model of logging timber freights by combine transport network. This model optimize of cargo-carrying and technological roading of forest bases in timber procurement enterprise and lumber factories. Authors developed procedures and functions, which allowed solving optimization of cargo-carrying and technological roading of forest bases in timber procurement enterprise and lumber factories. Authors also analyze technological process on cut-over land, loading bay and railheads. This reporting allows to reduce transport costs and makes optimal schedule of logging timber freights.

In article it is briefly considered stages of formation of definition of strategic marketing in scientific literature of Russia. The importance of a services sector in economy and the importance of modernization of the given sphere for the general development of economy as a whole locates. The analysis of dynamics of paid services to the population that will allow to reveal the sphere of servants with the greatest volume of consumption among the population is carried out. Are considered the sphere of transport services of the Rostov region, as a result of research SWOT analysis of marketing strategy is carried out to projections to the sphere of transport services of the Rostov region and recommendations to transport companies of the Rostov region for a choice of suitable marketing strategy are made.

The article considers the regulatory and estimated characteristics, as well as proposals for the estimate of the strength and deformability characteristics for possible practical inculcation of fiber concrete with aggregate distribution of fibers produced by the shuttle and conveyor technology, and reinforced concrete structures of them.

Keywords: regulatory, estimated characteristics, stress-strain diagram, compression, tension.

One of the most important technological aims is to obtain a fiber concrete with uniform (aggregate) distribution of the fibers by volume of concrete, from which depend essentially on the constructive and performance attributes of fiber concrete. Authors proposed pipeline technology of preparation of fiber concrete with aggregate distribution of the fibers, also they studied changes in its structural characteristics, and developed estimated recommendations for the evaluation of its strength and deformability characteristics and strain diagrams in compression and tension
