The corrosion inhibition of copper alloy was studied experimentally in our previous work. The effect of phenylenediamine (PDA), Tetraethylenepentamine (TEPA), Diethylenetriamine (DETA) and Ethylenediamine (EDA) were used and evaluated. Quantum chemical and theoretical calculations were carried out in present study. Several quantum parameters are obtained via two computer software. Maximum energy band gab was 6.263 eV for PDA, while minimum one was 3.057 eV in the case of EDA, which support the experimental results of inhibitors efficiency. A comparative study was done. Theoretical calculations are a powerful way for estimation inhibitors efficiencies. A good correlation was seen between experimental inhibitor efficiency and theoretical one with high correlation coefficients. © 2017, University of Mohammed Premier Oujda Morocco.

In a mobile environment and at high data rate transmission, channel makes highly hostility. This paper presents multi-orthogonal code modulation (MOCM) as a novel spread spectrum modulation scheme for spreading a transmission system to combat the channel effects and it is suitable for high data rate communications. This scheme uses an orthogonal chaotic signal to modulate and spread the information; therefore, a good information security is produced. The obtained results in noisy channel demonstrated the superiority of using MOCM compared with using traditional PSK for direct sequence spread spectrum (DS-SS); MOCM achieves a significant improvement in terms of bit error rate (BER) and data transmission rate. © 2016 by Begell House, Inc.

Objectives: To determine the role of Bcl2 and p53 gene expression in the pathogenesis of antral-predominant non-atrophic gastritis (APNG) according to Helicobacter pylori (HP) cytotoxin-associated gene A (CagA) status. Methods: Multiple antral biopsies were taken from 78 patients for rapid urease test, histopathology, Bcl2 and P53 immunohistochemistry and HP CagA in situ hybridization. Results: CagA was detected in 74.35% cases. There was no significant difference in Bcl2 expression among CagA+ and CagA− APNG cases. Significant differences in polymorphonuclear neutrophils (PMNs) and lymphocytes grades were detected among CagA+ and CagA− APNG cases. There was no significant correlation among patients’ age, inflammatory infiltrates, Bcl2, p53 expression. CagA has positive correlation with p53 (p=0.001), PMNs grade (p=0.027), lymphocytes grade (p=0.003), inflammation intensity (p=0.006), and inflammation activity (p=0.007). Bcl2 has no significant correlation with p53, CagA, PMNs, and lymphocytes indexes. P53 expression has significant correlation with PMNs and lymphocyte grades (p=0.000), inflammation intensity (p=0.003), and inflammation activity (p=0.002). PMNs grade has positive correlation with lymphocyte grade, inflammation intensity, and activity (p=0.000). Lymphocyte grade has a significant correlation with inflammation intensity and activity (p=0.000). Inflammation intensity has a significant correlation with inflammation activity (p=0.000). Conclusions: CagA cytotoxin has direct effect on P53 gene and indirect effect on Bcl2 gene expression in APNG cases. Bcl2 and P53 expression do not get affected by patient’s age and gender. PMNs grade, lymphocytes grade, inflammation intensity, and inflammation activity affected directly by P53 and CagA cytotoxin expression and indirectly by Bcl2 expression. The balance of P53-Bcl2 pathways play a vital role in pathogenesis of HP and CagA-induced APNG. © 2017 The Authors.

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.

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.

This paper presents the analytical methods of a SDOF system analysis subjected to blast loadings. Two types of blast wave applied for study the non-linear behavior of system, the analysis focused on displacement time history responses which form the basis for studying behavior of SDOF System under blast loadings. For two types of blast function simple pulse, and bilinear pulse, many parameters used for obtained time history plots, computed energy, and Hysteresis Analysis. The results obtained from a computer program NON-SDOF clarified the effect of type of blast wave on the behavior of system. © 2010 EuroJournals Publishing, Inc.

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.
