Research ArticleOpen accessIn the author namesHistomorphochemical Studies on Accessory Glands of Iraqi Blackbuck (Caprus Hircus)Waleed J. A. Al-Kelaby, Wafaa Hadi Mousa AL-Hashem, Zahraa S. M. Al Kaabi et al.Thevarious species' male accessory genital glands vary and are intimately relatedto the pelvic urethra. These glands secrete nutritional substances, buffers,and mucous to increase volume, serve as lubricants, reduce the minor acidity ofvaginal contents and make the environment more hospitable to motile sperm. Thisstudy aims to study the histological and histochemical structure of the maleaccessory sex glands in caprine Iraqi breeds. … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 4 · 25 Nov 2022 · 5,387 accessesView PDFCite
Research ArticleOpen accessIn the author namesKinetics and Adsorption Isotherm of Ibuprofen onto Grafted β-CD/Chitosan PolymerHashem Bany-Aiesh, Raid Banat, Khaldoun Al-Sou’odThe adsorption of the Ibuprofen (Ibu) drug on β-cyclodextrin (β-CD) grafted chitosan polymer was studied under different experimental conditions. The effect of Ibu concentration, mass of β-CD grafted chitosan polymer as adsorbent, contact time, temperature and pH were investigated. Three equilibrium models, Langmuier, Freundlich and Temkin isotherm models were analyzed to evaluate the adsorption isotherms. The adsorption isotherms were best … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 20 Nov 2015 · 7,450 accessesView PDFCite
Research ArticleOpen accessIn the author namesModification of Carbon Steel by Laser Surface Melting: Part II: Effect of Laser Beam Power on Microstructural Features and Surface HardnessHashem F. El-Labban, M. Abdelaziz, Essam R.I. MahmoudThe surface hardness has an important effect on the wear resistance of different materials. The present study aims to improve the surface hardness of carbon steel through the application of laser surface melting with suitable conditions. The laser beam power and travelling speed are the main factors that affect the properties of the treated zone. In this study, three different … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 30 Jan 2014 · 7,211 accessesView PDFCite
Research ArticleOpen accessIn the author namesCharacterization of Aluminum Alloy-Based Nanocomposites Produced by the Addition of AL-TI5-B1 to the Matrix MeltHashem F. El-Labban, M. Abdelaziz, Essam R.I. MahmoudThe present study is an attempt to produce aluminum matrix nanocomposites using a certain aluminum alloy (which its melt has high fluidity) as a matrix material and reinforced with hard and stable fine (nano-sized) precipitates. Therefore, Al-Ti5-B1 master alloy and Al-Si alloy of high silicon content were proposed for preparation of such nanocomposites. Three nanocomposites were prepared by adding Al-Ti5-B1 … …Current Research in Nanotechnology, Vol. 4, Issue 1 · 9 Jan 2014 · 7,130 accessesView PDFCite
Research ArticleOpen accessIn the author namesModification of Carbon Steel by Laser Surface Melting: Part I: Effect of Laser Beam Travelling Speed on Microstructural Features and Surface HardnessHashem F. El-Labban, M. Abdelaziz, Essam R.I. MahmoudThe present study aims to improve the surface hardness of carbon steel by application of laser surface melting of effective conditions. The travelling speed of laser beam during this treatment is one of the important treatment conditions. This study aims to investigate the effect of laser surface melting with different beam speeds on macro and microstructure as well as the … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 2 Jan 2014 · 7,407 accessesView PDFCite

Before the beginning of the experiments, acute and subacute studies were carried out in control animals first to investigate the LD50 of this extract. In the experimental design, adult male albino rats were divided into five groups: (1) … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 1 · 9 Dec 2013 · 8,156 accessesView PDFCite
Research ArticleOpen accessIn the author namesSHADOW DETECTION USING COLOR AND EDGE INFORMATIONMaryam Golchin, Fatimah Khalid, Lili Nurliana Abdullah, Seyed Hashem DavarpanahShadows appear in many scenes. Human can easily distinguish shadows from objects, but it is one of the challenges for shadow detection intelligent automated systems. Accurate shadow detection can be difficult due to the illumination variations of the background and similarity between appearance of the objects and the background. Color and edge information are two popular features that have been … …Journal of Computer Science, Vol. 9, Issue 11 · 5 Oct 2013 · 7,965 accessesView PDFCite
Research ArticleOpen accessIn the author namesEvaluation of Energy Aspects of Apple Drying in the Hot-Air and Infrared DryersSeyed Hashem Samadi, Issa LoghmaniehDrying is an energy-intensive process. In general, heating and evaporation require large quantities of energy. This study has been conducted to evaluate analysis for dying apple slices in two drying systems including hot-air convection and infrared drying. The apple samples were dried at temperatures of 90, 120 and 150°C and radiation intensity of 0.22, 0.31 and 0.49 W/cm2 in the … …Energy Research Journal, Vol. 4, Issue 1 · 26 Aug 2013 · 8,013 accessesView PDFCite
Research ArticleOpen accessIn the author namesAsymptotic Giant Branch Stars Migration from the Central of the Milky Way Galaxy to our Sun’s Birthplace and its Relation with Silicon Carbide GrainsAhmad Hashem AbdelhadiSilicon carbide grains found in meteorites are peculiar in their age and isotopic ratios; they formed before the Sun was born and their isotopic signature indicates that they come from a different galactic region. This study aims to seek a possible paradigm for such richness and peculiarity through Monte Carlo simulation of scattering of Asymptotic Giant Branch (AGB) stars off … …Space Science International, Vol. 1, Issue 1 · 20 Jun 2013 · 7,058 accessesView PDFCite
