Studying the Utility of Using Reed and Sawdust as Waste Materials to Produce Cementitious Building Units
...Show More Authors

In this research, the possibility of using waste wooden materials (reed and sawdust) was studied to produce sustainable and thermal insulation lightweight building units , which has economic and environmental advantages. This study is intended to produce light weight building units with low thermal conductivity, so it can be used as partitions to improve the thermal insulation in buildings. Waste wooden materials were used as a partial replacement of natural sand, in different percentages (10, 20, 30, and 40) % . The mix proportions were (1:2.5) (cement: fine aggregate) with w/c of 0.4. The values of 28 days oven dry density ranged between (2060-1693) kg/m3.The thermal conductivity decreased from (0.745 to 0.222) W/m. K .The percentages of decrease in 28 days compressive strength were (30.8, 36.8, 50 and 56.4) % .The flexural strength increased at low replacement of reed and sawdust content, and then it decreases with the increase of reed and sawdust content. At the end of the work, building units were produced from selected mix (natural sand with 30 % reed and sawdust) (MS30) .Two types of brick units were produced; the first type without coating reed or sawdust and the second type was coated with bituminous emulsion. The coating with bituminous emulsion increased the compressive by about (20.3) % and the water absorption was reduced by about (30.4) %. Efflorescence was almost negligible for both types of bricks.

Synthesis, Characterization and Studying Mass Spectra and Thermal Analysis for Complexes of Some Metal Ions and Determining their Activity as Antioxidants
...Show More Authors

The new azo dye was prepared from the reaction of the diazonium salt derived from 3-aminophenol with 2- hydroxyquinoline, then it was used to prepare a series of complexes with the chlorides of cobalt, chromium, copper, nickel, platinum, palladium and ammonium molybdate. The ligand was identified by a proton and carbon nuclear magnetic resonance spectroscopy, and the compounds were collected. The prepared materials were subjected to infrared, ultraviolet-visible, and mass spectrometry, as well as thermogravimetric analysis, differential calorimetry, and elemental analysis. Conductivity, magnetic susceptibility, metal content, and chlorine content of the complexes were also measured. The results showed that the ligand behaves in a trigonal b

The measurements of neutron Fermi Age for selected Nuclear Reactor shielding materials using the Indium foil technique
...Show More Authors

The Neutron Fermi Age, t, and the neutron slowing down density,   q (r, t) , have been measured for some materials such as Graphite and Iron by using gamma spectrometry system UCS-30 with NaI (Tl) detector. This technique was applied for Graphite and Iron materials by using Indium foils covered by Cadmium and the measurements done at the Indium resonance of 1.46 eV. These materials are exposed to a plane 241Am/Be neutron source with recent activity 38 mCi. The measurements of the Fermi Age were found to be t = 297 ± 21 cm2 for Graphite, t = 400 ± 28 cm2 for Iron. Neutron slowing down density was also calculated depending on the recent experimental t value and distance.

Some Properties of Concrete Containing Waste Brick As Partial Replacement Of Coarse Aggregate And Addition Of Nano Brick Powder
...Show More Authors
Abstract<p>The accumulation of construction and demolition waste is one of the major problems in modern construction. Hence, this research investigates the use of waste brick in concrete. Seven different concrete mixes were investigated in this study: a control concrete mix, three mixes with volumetric replacement (10, 20, and 30)% of natural aggregate with brick aggregate, and two mixes with the addition of nano brick powder at a percentage level of 5– 10% by weight of cementitious materials. And the last one was mixed with 10% nano brick and 10% coarse brick aggregate. The experimental results for the additive of nano brick powder showed an enhancement in mechanical properties (compressive, </p> ... Show More

We need to know the basic facts concerning planning top and bottom limits including any critical levels or the threshold over which the cost would be much higher for land development. Therefore this paper concerned with Baghdad Municipality decision No.2/1004 dated 7/12/2004. The reason behind this decision is the hope to face up at least in the severe housing crisis in the city of Baghdad. This paper attempts to know the attitude of the local community in the general through a field study of people living near such dwelling where third floors are added of.

The Civil Liability of SWAT Units under American Law
...Show More Authors

It is necessary for police agencies both in the United States and elsewhere in the world to have rapid intervention units that carry out special tasks that regular police cannot handle, such as carrying out search warrants and arresting dangerous criminals, Armed robbery, release of hostages, terrorist incidents, mentally disturbed persons, and other special missions. They are supposed to be well trained, highly self-confident; working together, self-disciplined, and use the force to deal with the special situations they may face. Either there have been many cases in the United States of America against members of these units, personally or against the agencies, they work in because of excessive use of force in many cases that have been use

Minimizing the Principle Stresses of Powerhoused Rock-Fill Dams Using Control Turbine Running Units: Application of Finite Element Method
...Show More Authors

This study focuses on improving the safety of embankment dams by considering the effects of vibration due to powerhouse operation on the dam body. The study contains two main parts. In the first part, ANSYS-CFX is used to create the three-dimensional (3D) Finite Volume (FV) model of one vertical Francis turbine unit. The 3D model is run by considering various reservoir conditions and the dimensions of units. The Re-Normalization Group (RNG) k-ε turbulence model is employed, and the physical properties of water and the flow characteristics are defined in the turbine model. In the second phases, a 3D finite element (FE) numerical model for a rock-fill dam is created by using ANSYS®, considering the dam connection with its powerhouse
