The Effect of Urban Form on Temperature for Hot Arid Zones. The Case Study of Baghdad, Iraq
...Show More Authors

The research aims to determine optimal urban planning and design indicators of the urban clusters form in hot arid zones through studying of three urban areas in Baghdad, analyzing their urban indicators which include floor area ratio (FAR), urban clusters height, building density or land coverage, green areas, paved areas, shading ratio and how they affect urban temperature. The research reached the conclusion that air outdoor temperature on urban areas affected primarily by shadows casted on the ground, the effect of shaded area equals (5) times the effect of paved areas and (3.7) times the effect of green areas, this means that increasing urban clusters height in hot arid zones could minimize air outdoor temperature, buildings with (6) levels at minimum seems to be suitable to produce shadows in the ground plane of urban land, Increasing urban volumes in the vertical dimension height and compacting clusters or increasing FAR seem to be a smart strategy to minimize the hot dry climate effect and urban temperature.

A Vision to development the Islamic banks that operating under the financial system based on interest: (Iraq Case Study)
...Show More Authors

This paper aims to build a modern vision for Islamic banks to ensure sustainability and growth, as well it aims to highlight the positive Iraqi steps in the Islamic banking sector. In order to build this vision, several scientific research approaches were adopted (quantitative, descriptive analytical, descriptive). As for the research community, it was for all the Iraqi private commercial banks, including Islamic banks. The research samples varied according to a diversity of the methods and the data availability. A questionnaire was constructed and conducted, measuring internal and external honesty. 50 questionnaires were distributed to Iraqi academic specialized in Islamic banking. All distributed forms were subject to a thorough analys

Effect of Temperature On The Dissociation Of Cysteine In Aqueous Solutions From Conductivity Measurements
...Show More Authors

The  conductance  of  solu ti ons  of  cysteine  in  water  at  different concentrations and temperatures has been measured. These solutions obey Onsagcr  equation  and  give  linear  relations  especially  at  low concentrations. In more concentrated solutions a deviation from the equation is observed.

The molar conductivity of these solutions decreases with t he increase  in concen trations at constant temperature.

The  values of  the ionization constants and the conductivity at  infin ite

dilution for each temperature have been calcu lated.

Phases of Urban Development Impact on the Assessment of Thermal Comfort: A Comparative Environmental Study
...Show More Authors

Millions of pilgrims and visitors from numerous parts of the world flock to Karbala (one of the most prominent ideological and religious places in central Iraq) each year to visit the holy shrines in Karbala due to their sanctity. Many improvements have been made to the Two Holy Shrines (THS), the Shrines of Imam Husayn and Imam Abbas, and the area between them (ATHS), due to the high temperatures in this region and to improve pedestrian thermal comfort. Studies on improving outdoor thermal comfort in Karbala are scarce. Hence, this research aims to look into historical and current architectural changes and how they affect thermal comfort. On the hottest summer day, the ENVI-met software program was used to simulate the building des

Theoretical Study of the Photons Production Kinetic In Hot Quark-Gluon Plasma Matter
...Show More Authors

In this paper, we study flow of photons rate production in a quark-gluon QG plasma. General theory of this study is based on the field theory for hard interaction. The kinetic of photons production from hard interaction in charm with anti-top to production photons with gluon due to plasma phase at high temperatures (150, 200,250,300 and 350 MeV) .It has been investigated and studied using the postulate of quantum chromodynamic theory QCD .The photons production rate of hard photons with( GeV) are insensitive to strength coupling and depend mainly on the temperature of system T . Despite the different critical temperature (150 and 190MeV) comes, we find that same order of flow rate photons magnitude in both cases. In both cases, the f

Abstract<p>The present work included a study of benthic algae on two substrates: rocks and clay on a section of the Tigris River at the Al-Atifiyah site in the fall of 2018. The result of this study was recorded 89 species belong to 50 genus of benthic algae on both substrates and composed of Bacillariophyceae (59.6%, 61.2%), Chlorophyceae (25.8%, 20.4%) and Cyanophyceae (14.5%, 18.3%) respectively on epilithic and epipelic algae. The present study was recorded the highest total algae cell density (1173.2 cells *10<sup>3</sup>/cm<sup>2</sup>) on epilithic algae while the lowest total algae cell density was recorded on epipelic algae (76.95 cells *10<sup>3</sup>/gm).

Analysis and Study of the Effect of Atmospheric Turbulence on Laser weapon in Iraq
...Show More Authors

One of the most important challenges facing the development of laser weapons is represented by the attenuation of the laser beam as it passed through the layers of atmosphere.This paper presents a theoretical study to simulate the effect of turbulence attenuation and calculates the decrease of laser power in Iraq. The refractive index structure C_n^2 is very important parameter to measure the strength of the atmospheric turbulence, which is affected by microclimate conditions, propagation path, season and time in the day. The results of measurements and predictions are based on the Kolmogorov turbulence theory. It was demonstrated by simulations that the laser weapons in Iraq were severely affected due to the large change in temperatures,
