The service system has become a necessity of life in modern cities to be the most basic necessities of modern humans, they constitute a major base, which is based on the sustainability of life in the city and a standard measured through the degree of well-being and progress of civilized peoples and their interaction with the surrounding environment, making the services sector as a need not be an option, whenever the cities widened in population and space whenever provision of services and upgrading the quality and quantity more pressing, which made the subject of the services takes the biggest area of the trends and thinking of urban planners and those who in charge of drawing the cities policies. Considering that the processing and transfer of the water system with all its components (stations – water tanks -transmission and distribution pipelines), it is one of the most important parts of the services systems in the city. It has become a key element of the arteries of the establishment of life, but for several considerations of most important ( like storage of water and supplied with
constant pressure that balanced without wobbling at the peak daytime hours with the necessary provision of water to fight fires , as well as secured it to the sectors of city n the maintenance time of the parts of the water system or the occurrence of a failure, with the need to confirm the save and generate energy factor in renewable way). For this in whole and others, the elevated water towers cornerstone of the pillars of the water system was made that can be indispensable in providing outsourcing and distribution network , and on the grounds that the case study concerning our capital Baghdad and its suffering of the water distribution and pressure intermittent problems, this research aims to clarify the idea of the elevated water tanks have become an important actor and is a part of the process and transport of the water in the city's system, and that its presence in a thoughtful siting and storage capacities and sufficient numbers will reduce the cost of the service system and its problems and provides continuously a constant pressure is to rescue the city from the overtaking problems on the network, while avoiding the problems experienced by interruptions in the water supply process, especially in the summer, which will make the water tanks
as a necessary structures and essential elements of attractions for recreational activities and benchmarks functions within the city.
Background: Irrigation of the canal system permits removal of residual tissue in the canal anatomy that cannot be reached by instrumentation of the main canals so the aim of this study was to compare and evaluate the efficiency of conventional irrigation system, endoactivator sonic irrigation system,P5 Newtron Satelec passive ultrasonic irrigation and Endovac irrigation system in removing of dentin debris at three levels of root canals and to compare the percentage of dentin debris among the three levels for each irrigation system. Materials and methods: Forty extracted premolars with approximately straight single root canals were randomly distributed into 4 tested groups of 10 teeth each. All canals were prepared with Protaper Universal ha

Effect of Chlorococcum humicola alcoholic algae extract was studied on the growth of, Pseudomonas aeruginosa, and Klebsiella pneumonia, which were isolated from contaminated water. The extract of Ch. humicola showed a high efficiency in reducing the numbers of the two types of bacteria. . The removal rate of K. pneumonia were 0.0, 48.4 and 57.0, The removal rate of P. aeruginosa were 63.1, 79.8 and 82.9% after24,48, 72 h respectively. The results improved that the K. pneumonia is more sensitive than P. aeruginosa for algae extract concentrations used in study ,and the beast effective time is 24h for the two bacterial species The aim of the study was to eliminate microorganisms using the Alcoholic algae extract. Especially P. aeruginosa and

This paper deals with prediction the effect of soil re-moulding (smear) on the ultimate bearing capacity of driven piles. The proposed method based on detecting the decrease in ultimate bearing capacity of the pile shaft (excluding the share of pile tip) after sliding downward. This was done via conducting an experimental study on three installed R.C piles in a sandy clayey silt soil. The piles were installed so that a gap space is left between its tip and the base of borehole. The piles were tested for ultimate bearing capacity according to ASTM D1143 in three stages. Between each two stages the pile was jacked inside the borehole until a sliding of about 200mm is achieved to simulate the soil re-moulding due to actual pile driving. The re
