This paper investigates the effect of P-Delta in seismic response of structures with different heights. For indicating the effect of P-Delta, nonlinear static analysis (pushover analysis) and nonlinear dynamic analysis (Time history analysis) were conducted by using finite element software. The results showing that the P-Delta has a significant impact on the structural behavior mainly on the peak amplitude of building when the height of the structures increased. In addition, comparison has been made between concrete and steel structure.

Land zonings process like what achieved in this paper will help and of it's of a high interest point for the future of Kirkuk city especially urban planning and economic issues of the city. Also, it may be considered as a reference in solving the traffic jam problems in the city. Transportations and sounds of horn of vehicles are the major sources of traffic noise pollutions .Vehicular traffic noise problems are contributed by various types of vehicles such as heavy and medium trucks or buses or automobiles. During this study, six major regions within the city were selected (Governorate region, Baghdad road, Al Wasti, Al Askary, Al Nasir and North garage). A su...

This treatment plant is suffering some troubles associated with inefficient grit chambers due to lack of continuous maintenance resulting in abnormal grit deposits in the subsequent units of the treatment plant, especially digesters tanks. Field tests on these AGCs were conducted for evaluating their operating performance and their efficiency of removing TSS and oil and grease content during 30 days. Samples were taken from the inlet and outlet of each AGCs every 48 hour and were analyzed. The performance of these AGCs was also re-evaluated again by plotting the velocity distribution across a chosen chamber, at four sections perpendicular to the flow in the AGC. Certain operating problems were observed in the existing AGCs as a result of the experiments.

Kirkuk city is one of these cities, which suffer from a shortage of drinking water. People have adopted the use of different rooftop tanks to overcome this problem. This research focuses on studying the effect of storage time on the five main characteristics of drinking water, which include, acid index (pH), electrical conductivity (EC), total suspended solids (TSS), total dissolved solids (TDS), and turbidity (Tr). Three types of tanks were used predominantly (galvanized metal, plastic, and aluminum tanks). By analyzing the results, the characteristics of three samples of municipal source water obtained. Three samples were taken from each tank at different periods (4, 8, and 12 days). The results showed that the storage time affected the characteristics of drinking water. These characteristics differed from one tank to another. Metal tanks showed an increase in total dissolved s...

The conventional modelling technique usually deals with this problem by a linear method. The substitute modelling technique is an artificial neural network (ANN) system, and it is selected to reflect the non-linearity in the interaction among the variables in the function. Herein, synthesized deep eutectic solvents were used as a functionalized agent with carbon nanotubes as adsorbents of Pb2+. Different parameters were used in the adsorption study including pH (2.7 to 7), adsorbent dosage (5 to 20 mg), contact time (3 to 900 min) and Pb2+ initial concentration (3 to 60 mg/l). The number of experimental trials to feed and train the system was 158 runs conveyed in laboratory scale. Two ANN types were designed in this work, the feed-forward back-propagation and layer recurrent; both methods are compared based on their predictive proficiency in terms of the ...

Aluminum sulfate (alum) and polyelectrolyte (polymer) are the common chemical coagulants which are used in this process. The produced leachate in waste disposal places is considered to be one of the highly contaminated resources from the physical, chemical, and biological point of view. In Sulaimaniah, Tanjaro was found to be one of those solid waste landfill areas. Okra is used for the treatment of raw leachate samples that obtained directly from Sulaimaniah – Iraq solid waste sanitary landfill area. Fresh solid waste samples of the leachates were taken and tested for their heavy metals concentrations contents. It was found that the leachate contains a high amount of heavy metals of cadmium, chromium, copper, nickel, and zinc. By using conventional coagulants of alum, polymer and natural indigenous okra (as a primary coagulant or in combination with the other two primary coagulants) ...

During this study, six major regions within the city were selected (Governorate region, Baghdad road, Al Wasti, Al Askary, Al Nasir and North garage). A survey for all those six regions were taken place and noise measurements were captured at points or near to the intersections for a duration of three different periods days per a week [ Sunday 3 rd , Monday 4 th , and Tuesday 5 th ] of January 2016. The results showed a high level of noise pollution and super passing on many occasions to the prescribed levels by Central Pollution Control Board (CPCB) , maximum level noise pollution value was 94.6 dB(A) in AlWasti region near to the road that leading to Kirkuk university , while minimum level noise pollution value was 48 dB(A) in AlNasir region. As a result, a noise map zoning was prepared for Kirkuk City for top peak working three days. The prepared noise distribution map will help and could be used as a considerable point for the future during designing projects related to transportations. Also in another hand, the map reflected indirectly the amount of regional air pollutions. High distributed noise pollution zones means a zone of a high air pollutions levels specially Cox and Nox gaseous pollutions.
