This study was conducted to examine the effects of Zingiber officinale (ginger) powder on male broiler reproductive system. Zingiber officinale was administered in the feed of two groups of male broiler breeder (30 wk age) at levels of 5 and 10 kg/ton, Third group was a control group (no additive). Treatments were ejaculate volume, sperm concentration, counts, movements, motility and abnormality, blood serum LH, FSH and testosterone concentration. The ginger caused a significant increase (p<0.05) in ejaculate volume, sperm concentration, counts, movements and a significant decrease (p<0.05) in motility and abnormality. There was also a significant increase (p<0.05) in blood serum LH, FSH and testosterone levels. Our results indicated that Zingiber officinale powder possesses pro-fertility properties in male broiler which might be a product of androgenic activities. © Asian Network for Scientific Information, 2011.

AIM: To determine the risk factors associated with H. pylori infection and possible correlation with clinicopathological parameters. MATERIAL AND METHODS: Gastroduodenal biopsies were examined by rapid urease test and Gram staining. Cag A cytotoxin was detected by in situ hybridization. RESULTS: Risk of H. pylori acquisition reported as following: Males have 1.38 fold, rural residents have 0.63 fold, Nonsmokers have 0.39 fold, mild smokers have 18 fold, and moderate smokers have 1.4 fold while heavy smokers have 1 fold. A person who’s in contact with animals has 1.52 fold risks. Illiterates and patients with primary education have 5.36 & 3 fold risk respectively. Pa-tients under proton pump inhibitor (PPI) therapy have 1.02 fold. Patients under NSAID therapy have 3.48 fold while nonalcoholic Patients have 0.75 fold. Patients using tap water have 0.45 fold risk. H. pylori infection positively correlated with age, weight loss, and heartburn. H. pylori inversely correlated with endoscopic diagnosis, Cag A positivity, and education level. Cag A positivity corre-lated with animal contact and NSAID usage. CONCLUSIONS: Several life style factors, education, animal contact, using of PPI, and NSAIDs increase the risk of H. pylori infection. Weight loss and heartburn cardinal signs for H. pylori infec-tion. Endoscopic diagnosis and clinicopathological parameters not strictly associated with Cag A positivity. © 2015 Ali Ibrahim Ali AL-Ezzy.

Two types of composites consisting of single–walled carbon nanotubes (SWNTs) and mwuti-walled carbon nanotubes (MWNTs) with titanium dioxide (TiO2-P25) were synthesized by simple evaporation methods. These composites were characterized by UV–vis diffuse reflectance, XRD, Raman spectroscopy, Fluorescence spectroscopy and Surface area (SBET). The results show that Carbon Nanotubes (CNT) which used to synthesis composites (TiO2/CNTs) has succeeded in increased the activity of TiO2when exhibits higher photocatalytic activity than TiO2. The multi walled carbon nanotubes MWNTs were succeeded to increase the adsorption for synthesis composites more than SWNTs, while SWNTs succeed to improve the activity of photocatalytic degradation of TiO2. The enhancements of the activity for the composites by the two types of CNTs can explain by two parameters: the first were increased the surfaces area for synthesis composites and the second was translating the exited electron e-from conduction bands (CB) of TiO2 to the surfaces of CNTs which causing reduces the recombination of e-/h+. © 2016, Sphinx Knowledge House.

Mathematical and statistical modelling has been used in determining the relation of response as a function of independent variables. Corrosion inhibition data (response) as a function of temperature, acid concentration and inhibitor concentration (independent variables) of some steels in acidic environments were collected from literature and used as source for generalisation of two corrosion rates models. About 100 researches and papers were selected and used as a source of models data. These models could assist corrosion engineers in predicating corrosion rate value and some kinetics parameters. Two and three variable models were tested and estimated by a computer program. Regression method was based on the Levenberg-Marquardt estimation method. Two models represent corrosion data successfully with a high correlation coefficient. Results showed good agreement between experimental and theoretical results. Correlation coefficients values were 0·9952 and 0·9976 for two and three variables models respectively, which indicate a strong relationship between variables. © W. S. Maney & Son Ltd. 2013.

Two methods were experimented to regenerate the spent ZnO catalyst. The first one involved combustion by air while the second one involved steam treating of catalyst. The results abstracted from the first method showed that it is not suitable and reliable in regeneration of the catalyst because of the formation of zinc sulphate which cause blockage of the catalyst pores and hence reduce its activity. The steam regeneration method seem to be very practical and promising as the catalyst regenerated have a good activity which approached 97 %, in addition, the physical and chemical properties of the regenerated catalysts was very close and similar to the commercial new one © EuroJournals Publishing, Inc. 2010.
