The seismic can be threatened the stability of the flexible body of the earth dam and can cause completely damaged or deformation on their embankment. Therefore, a geotechnical engineer needs to know the effect of earthquakes on earth structures. The change in the seismic zone that recently Iraq affected is the reason for this research, in general, in 2017, the whole of Iraq, and in particular the region, where the Al-Wand earth dam (the subject of the study) is located, was exposed to several earthquakes. This research project mainly aims to study the behavior of Al-Wand earth dam under seismic load in different conditions by simulating Al-Wand earth dam through numerical modeling and study the influence of water reservoir level, earthquake peak acceleration, and duration. This paper includes an analytical study of the effect of this earthquake on Al-wand earth dam, using the quake/w program, which is a sub-program of geo-studio, also the stability of the dam was studied under the influence of earthquakes of different intensity, and a review of the impact of different water levels on the stability of the body dam. Where the response of the Al-wand dam was analyzed to earthquakes at the normal and the maximum water level, and by using a quake that may have been exposed to Iraq in 2017 and used the time of 100 seconds and using an acceleration of 0.02g, 0.03g, 0.05g measured by units of ground acceleration to identify the behavior of displacements, effective stress and pore water pressure during the earthquake.
Abstract
This current research aims to make theoretical frame for the thoughts and principle knowledge for high performance work system ،also trying to know the role that high performance work system practices which is (Effective staffing، comprehensive training، providing work career، and employee participation) play to enhance the organization effectiveness ، although knowing the principles of high performance work system which is: (Shared Information، Knowledge Development Performance and Reward linkage Egalitarianism)and its effect on the organizations. As well as defining the special concept of High performance wo

Show MoreSilver-bismuth iodide (ABI) ternary semiconductors, such as AgBi2I7, AgBiI4, Ag2BiI5, and Ag3BiI6, have emerged as promising lead-free light absorbers for photovoltaic applications due to their favorable optoelectronic properties. Despite recent advances that have improved power conversion efficiencies from ∼1% to over 5%, ABI-based solar cells still show substantial open-circuit voltage (VOC) losses of up to ∼1 V, which significantly hinder the device performance. These losses have been experimentally attributed to the non-radiative recombination originating from intrinsic defects, however, theoretical understanding of these defect mechanisms remains limited. Here, using density functional theory calculations, we systematical
... Show MoreThe Adaptive Optics technique has been developed to obtain the correction of atmospheric seeing. The purpose of this study is to use the MATLAB program to investigate the performance of an AO system with the most recent AO simulation tools, Objected-Oriented Matlab Adaptive Optics (OOMAO). This was achieved by studying the variables that impact image quality correction, such as observation wavelength bands, atmospheric parameters, telescope parameters, deformable mirror parameters, wavefront sensor parameters, and noise parameters. The results presented a detailed analysis of the factors that influence the image correction process as well as the impact of the AO components on that process
Background: Sexual dysfunction in patients with schizophrenia was reported as one of the most distressing antipsychotics drug adverse effects and it is directly related to treatment compliance, but the subject seldom touched in the field of psychiatry in Iraq previously.Objectives: To assess and find out the impact of schizophrenia on Sexuality of the patient, and illustrate effect of anti-schizophrenic on sexual activityMethods: using DSM4-TR and ASEX scale questionnaires for 104 male participants from out 155schizophrenic patient were studied in sex clinic in Al-Rashad teaching hospital for psychiatric disease in Baghdad. The study extended for 22 months from 1st of July 2010 to the 1st of April 2012, t test and chi square test were us

Show MoreLos lingüistas no árabes suelen quedar perplejos a la hora de interpretar el fenómeno de Al-ḍdad, −normalmente traducido en español como palabras autoantónimas (1)− en la lengua árabe, en el que los arabistas, y entre ellos los españoles, han quedado sombrosos ante este fenómeno. El jefe del tribunal de la defensa de mi tesis me pidió que le explicara este fenómeno según mi teoría “El esquema básico de la referencia”; pues me dijo que no podía imaginar que una palabra tuviera dos significados opuestos, y en ese momento le expliqué la palabra albayn البين que significa la separación, o la relación o el enlace que comentar
