In the first part of the article discusses a number of issues related to engineering. Engineering is a field of scientific, technical and technological knowledge to ensure the practical implementation of ideas to improve the human environment at all stages of the life cycle of an idea from inception to disposal. Organization and maintenance of conditions of life of people identified the main concern of mankind from ancient to contemporary community formations of the international community, has given rise to the full range of human activities. The same motivation stood at the origins of civilization. Civilization - the next stage of development for the barbaric culture that teaches people to deliberate organized activities to targeted, predictable results. Engineering activities to meet these criteria. The subject of engineering is the human environment, research and monitoring her condition, prognosis of problem situations, organization and implementation of measures to improve the elements and the environment in general. The area of engineering for the benefit of human systems - organizing and conducting the study, the identification and resolution of problem situations at all stages of the life cycle of the system of ideological views and theories of fundamental and applied research , engineering - technical realization , the incorporation of innovation into the existing system . The author urges that in order to find practical ways to harness the potential of engineered solutions to the problems of social and cultural environment as the most important factor in the formation of the cultural level of society and personality.

This article describes the model of the pseudorandom sequences (PRS) generator developed in OrCAD program suite.The described model is applicable for radio systems modules circuits simulation that are using in the operation a PRS. The PRS generator implementation in OrCAD make possible to change PRS parametres immediately in the program, without using other software. A model specificity is that it is parametrised. Parametrization facilitates model control and that is reduce to a minimum necessary manipulations for changing of PRS type. The model is constructed on the basis of circuitry implementation of the linear feedback shift register (LFSR). For adjustment of model it is enough to instal code words setting starting state a LFSR, parametres of a signal of a clock source and to specify register tap output. As an example, used a 16-bit LFSR to create maximum length PRS, tap sequence {0, 5, 9, 13}. Emulation results are presented.

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.

The urgency and feasibility of application of biosensors with active biological layer for environmental studies was justified. A study of biosensors of various configurations to build a test system of environmental pollution control and determine the degree of aquatic toxicity was conducted. A simulation model of biosensor system was built. The selectivity of the biosensor was determined by theoretical experiments in which the analytical signal of the biosensor for biologically active layer without other biologically active substances was determined. The relationship between the type of transducer and biologically active substance was revealed. The software implementation of bisensor system was developed that reveals a number of pollutants and allows using not only different converters, but also different strains.
