Adsorption of Some Alephatic Dicarboxylic Acids on Zinc Oxide: A kinetic and Thermodynamic Study
...Show More Authors

The adsorption of Malonic acid, Succinic acid, Adipic acid, and Azelaic acid from their aqueous solutions on zinc oxide surface were investigated. The adsorption efficiency was investigated using various factors such as adsorbent amount, contact time, initial concentration, and temperature. Optimum conditions for acids removal from its aqueous solutions were found to be adsorbent dose (0.2 g), equilibrium contact time (40 minutes), initial acids concentration (0.005 M). Variation of temperature as a function of adsorption efficiency showed that increasing the temperature would result in decreasing the adsorption ability. Kinetic modeling by applying the pseudo-second order model can provide a better fit of the data with a greater correlation coefficient, which indicates that the adsorption process follow the pseudo-second order kinetics. The negative values of Gibbs free energy and the enthalpy change confirm the spontaneous and exothermic nature of the adsorption process. A good ability of zinc oxide to remove aliphatic dicarboxylic acids from its aqueous solutions has been found, and the chain length of the acids has no significant effect on its adsorption.

Extraction of Essential Oil from Iraqi<i>Eucalyptus Camadulensis</i>Leaves by Water Distillation Methods
...Show More Authors

The extraction of Eucalyptus oil from Iraqi Eucalyptus Camadulensis leaves was studded using water distillation methods. The amount of Eucalyptus oil has been determined in a variety of extraction temperature and agitation speed. The effect of water to Eucalyptus leaves (solvent to solid) ratio and particle size of Eucalyptus leaves has been studied in order to evaluate the amount of Eucalyptus oil. The optimum experimental condition for the Eucalyptus oil extraction was established as follows: 100˚C extraction temperature, 200 rpm agitation speed; 0.5 cm leave particle size and 6:1 ml: g amount of water to eucalyptus leaves Ratio.

Abstract<p>Due to the wide distribution through the Iranian Plateau, especially in its western parts adjacent to Iraq’s northeastern borders, the occurrence of Brandt’s Hedgehog <italic>Paraechinus hypomelas</italic> (Brandt, 1836) was suspected, but no confirmed records were made. In 2021–2023, several sightings were obtained during <italic>in situ</italic> surveys in the Bamo-Khoshk Mountains in the Kurdistan region-northeastern Iraq which confirm the first occurrence of this species in the country.</p>

Iraqi government policy towards the Kurds in light of British documents, February 1963 - April 1966
...Show More Authors

The Kurds' positions were characterized by insistence on their rights during the monarchy and choosing various solutions to obtain independence. After the revolution of July 14, 1958, the Kurds welcomed it, and the leaders of the Kurdistan Democratic Party sent a telegram to the Free Officers Organization congratulating them on the new era in order to build sound and correct relations between the two parties. However, the military conflict was renewed between the Iraqi government and the Kurds and continued even after the coup of February 8, 1963, and all the subsequent negotiating and peaceful attempts to resolve the Kurdish problem until 1966. It was a state of double contradiction for both parties that thwarted the peaceful attempts. The

GIRL’S TRADITIONA COSTUME IN MAKKAH AL MUKARRAMAH _ KINGDOM OF SAUDI ARABIA”: ليلى عبد الغفار فدا
...Show More Authors

This research is concerned with documenting traditional clothes of girls and children in Makkah in the past 100 years and is a step towards preserving our heritage which is exposed to rapid changes. The researcher’s goal is to contribute to the Saudi’s folklore studies with a qualitative study of clothes and ceremonies used in the past. Sources of information were collected from human and material samples, ceremonies, clothes, techniques used to embellish them and from previous studies. The study concludes that aspects of civilization influenced clothes and resulted in a great deal of change. Children wore scale-down versions of adult clothing. Costumes were rich by their styles and adornment. The researcher emphasizes the importance

...Show More Authors

Abstract :H.pylori is an important cause of gastric duodenal disease, including gastric ulcers, Mucosa-associated lymphoid tissue (MALT), and gastric carcinoma. biosensors are becoming the most extensively studied discipline because the easy, rapid, low-cost, highly sensitive, and highly selective biosensors contribute to advances in next-generation medicines such as individualized medicine and ultrasensitive point-of-care detection of markers for diseases.  Five of ten patients diagnosed with H.pylori ranging in age from 15–85 participated in this research. who [gastritis, duodenitis, duodenal ulcer (DU), and peptic ulcer (PU)] Suspected H.pylori colonies w
