Alpha-Alumina Extraction from Al-Ga'ara Bauxite
...Show More Authors

The bauxite produced from Al-Ga 'ara area in Al-Enbar containing 50.4 wt. percentages Al2O3 was used for a- alumina production.                                                                                                

For α-alumina production bauxite was mixed with calcium carbonate in a ratio 1:3 and the mixture was burned at temperature range 1l 50-l350°C, cooled to 500°C; crushed and ground. The powder produced treated then with 6% sodium carbonate solution using different temperature (60-100°C) for fifteen minutes. After filtration, the produced sodium alurninate solution was reacted with 2% of calcium hydroxide at 98°C for thirty minutes. The filtrate was carbonated with purified C02 gas at 70°C for different times (30-180 min) and different flow rates (20-80 cm3/min).

Alumina was precipitated as hydrate, then washed with water, dried at 110°C, and calcined at 1200°C. The produced α­ Al2O3 was identified   by X-ray diffraction.

Shot Peening Time Effect on Corrosion Behaviors of Al Alloy 2024-T3
...Show More Authors

In this study many specimen s were prepared from 2024-T3 Aluminum alloy for corrosion test by the dimensions of (15*15*3) mm according to ASTM G71-31 and then subjected to shot peening process at different time (15, 30, 45) minutes using steel ball having a diameter of 2.75 mm and Rockwell Hardness of 55RC to induce compressive residual stress which were measured using X-Ray diffraction method, surface roughness and   hardness were tested before and after peening. Electrochemical corrosion test by Tafel extrapolation method was carried out in an environment of 3 .5% NaCl solutions (sea water) where Corrosion rate calculated using Tafle equation.

The obtained results show a favorable influence of SP treatment

Animation from a legitimate perspective
...Show More Authors

This study aims at investigating the partial Islamic rules of preparing and distributing cartoons in order to issue an overall Islamic rul. To reach an end, descriptive and analytical approaches are adopted to clarify the nature of cartoons and other related concepts. The researcher, as well, with reference to verses of the Holy Quran, tradition (Hadith) and Islamic jurists, adopts a deductive approach to issue Islamic rules related to the industry of cartoons and it's distribution
The study consists of three sections. The first Section addresses the following issues: Definition animation; and related wordy. The second Section: Origin of Cartoon's history and it's negative and positive effects. The third Section: Islamic rules related

Meaning From a Logical Perspective
...Show More Authors

This paper is intended to focus on the existing relation between 'logic' and 'meaning', and how 'meaning' is looked at through logical perspective. Besides, this paper adopts simple logical symbols to represent some aspects of meaning.

    Since meaning is still regarded as a thorny area that needs further study to determine its nature and borderline, this paper proposes to resort to logic and logical rules. This paper points out how logical rules are used and how they clarify some oblique sentences. The paper also sheds light on how meaningful sentences are logically symbolized and how logic can define the borderline of meaning in an adequate manner. This paper hypothesizes that logic, l

Removal of Lead Ions from Wastewater by using a Local Adsorbent from Charring Tea Wastes
...Show More Authors

   Adsorption of lead ions from wastewater by native agricultural waste, precisely tea waste. After the activation and carbonization of tea waste, there was a substantial improvement in surface area and other physical characteristics which include density, bulk density, and porosity. FTIR analysis indicates that the functional groups in tea waste adsorbent are aromatic and carboxylic. It can be concluded that the tea waste could be a good sorbent for the removal of Lead ions from wastewater. Different dosages of the adsorbents were used in the batch studies. A random series of experiments indicated a removal degree efficiency of lead reaching (95 %) at 5 ppm optimum concentration, with adsorbents R2 =97.75% for tea. Three mo
