Journal of Agriculture and Environment for International Development , 2012,
Abstract: Résumé : L’étude a évalué l’approvisionnement en porcs et viande de porc de la ville de Bobo-Dioulasso (Burkina Faso). Les données ont été collectées par enquête transversale et rétrospective auprès de 623 éleveurs en 2003, de 34 commer ants/transformateurs en 2005 et 2006 et auprès de l’Abattoir Frigorifique de Bobo-Dioulasso (AFB) en 2009. Les résultats ont montré que les porcs provenaient des élevages urbains et périurbains (38%) et des villages au-delà de la périphérie de Bobo-Dioulasso (62%). La production de viande de porc à l’AFB s’est accrue entre 2001 et 2006. Les carcasses, les poumons et le foie ont été surtout saisis aux motifs de tuberculose, de congestions et de cysticerques. Sur 982kg de viande traitée quotidiennement par les acteurs (35), 80% l’a été par des r tisseurs (88,24% des acteurs), 17% par des charcutiers (5,88%), 2% par les bouchers (2,94%) et 1% par les restaurateurs (2,94%). Des études complémentaires sur la rémunération de la production et de la commercialisation et sur la qualité des produits (porcs, viande et produits transformés) seront nécessaires pour impulser l’accroissement de la part des viandes porcines dans l’approvisionnement de la ville de Bobo-Dioulasso Mots clés : Approvisionnement, porcs, viande de porc, Ville de Bobo-Dioulasso
Analysis of Social, Psychological and Other Factors on College Dropout Rates among African American Students  [PDF]
Salam Khan
Advances in Applied Sociology (AASoci) , 2017, DOI: 10.4236/aasoci.2017.78020
Abstract: This study explored the African American college students’ retention behavior and identifies the effect of different social, psychological and other factors. Randomly selected students from predominant African American university completed the perceived stress scale, self-motivation scale, parental involvement, childhood economic situation, mentorship and drug and alcohol use questionnaire. Non-parametric analyses suggested that higher stress level, childhood poverty, lack of parental involvement or support, without a mentor support and lack of self-motivation increase the likelihood of dropping out from college. This study’s findings have important implications for college retention among African American students.
Assessment of Surfactant Modified Activated Carbon for Improving Water Quality  [PDF]
Kamoru A. Salam
Journal of Encapsulation and Adsorption Sciences (JEAS) , 2019, DOI: 10.4236/jeas.2019.91002
Abstract: Effluents containing inorganic contaminants are releasing into the environment untreated despite being hazardous to man and environment. It is costly and unsustainable to use conventional methods to remove them from dilute aqueous solution. Adsorption involving granular activated carbon is an alternative method for treating such effluents. Granular activated carbon is structurally strong, highly resistance to attrition and wearing, large and can easily separate from the effluents. However, its surface is highly hydrophobic and has little surface charge thereby reducing its adsorption capacity for anion or cation. This article reviews surfactant modification of activated carbon to enhance its adsorption capacity for inorganic contaminants and key factors affecting the adsorption efficiency. They include initial concentration of contaminants, contact time, solution pH, solution temperature, adsorbent concentration, ionic strength, competing ions, type of surfactant, and surfactant concentration. The modified activated carbon usually shows maximum contaminant uptake around its critical micelles concentration. Surfactant modification reduces specific surface area and/or micro pore volume but hot NaOH or HNO3 treatment before surfactant modification minimises this drawbacks and increases the net surface charge. Overall, surfactant modification is a simple but efficient method of enhancing adsorption capacity of activated carbon for removing anion or cation from aqueous solution. However, a handful publication is available on the regeneration of the spent (saturated) surfactant modified activated carbons. Hence, more research efforts should be directed towards proper regenerating reagents and the optimise conditions such as contact time, concentration, and temperature for regenerating spent modified activated carbons.

Journal of Diabetes Mellitus (JDM) , 2014, DOI: 10.4236/jdm.2014.41005

Objectives: Diabetic nephropathy is the leading cause of chronic kidney disease. The pathogenesis of DN remains incompletely understood. It has been recently demonstrated that inflammatory processes play a significant role in the development and progression of DN. Toll-like receptors play a fundamental role in the innate immune system by triggering proinflammatory signaling pathways. Our aim is to evaluate the expression of TLRs on monocytes and relate their expression with inflammation in HD patients with & without diabetic nephropathy. Method: In a case control study (60) patients from Alkasr El Aini Hospital on hemodialysis were divided into two groups: Group 1, 30 patients on heamodialysis not due to diabetic nephropathy, Group 2, 30 patients on heamodialysis due to diabetic nephropathy, compared to Group 3, including 30 healthy controls. All participants were subjected to: Full medical history, complete physical examination, Serum creatinine, uric acid, A1C, fundus examination, detection of TLR2, TLR expression by real time PCR in peripheral blood mononuclear cells. Data were statically calculated using SPSS, comparision between groups was done using student T test comparing 2 groups, correlation using spearman’s correlation. Results: Diabetic had significantly increased TLR2, TLR4 mRNA in peripheral blood mononuclear cells compared to controls and non diabetics patient on heamodialysis (p < 0.001), TLR2, TLR4 significantly correlated with dialysis duration in diabetic (p < 0.001), no correlation with A1C in relation to TLR2 (p = 0.078), TLR4 (p = 0.163). Conclusion: TLR2, TLR4 were significantly elevated in diabetic on dialysis initiating event in the pathogenesis of DN, providing a link between hyperglycemia and hypoxia with inflammation and fibrosis within the kidney. Hence, therapeutic interventions aimed at targeting the inflammatory component through interruption of TLR signaling may be a novel strategy to target prevention and treatment of DN.

Microstructure, Corrosion, and Fatigue Properties of Alumina-Titania Nanostructured Coatings  [PDF]
Ahmed Ibrahim, Abdel Salam Hamdy
Journal of Surface Engineered Materials and Advanced Technology (JSEMAT) , 2011, DOI: 10.4236/jsemat.2011.13015
Abstract: Air Plasma spray process was used to deposit a conventional and nanostructured Al2O3-13 wt% TiO2 coatings on a stainless steel substrates. Morphology of the powder particles, microstructure and phase composition of the coatings were characterized by XRD and SEM. Potentiodynamic polarization tests and Electrochemical Impedance Spectro- scopy (EIS) were used to analyze the corrosion of the coated substrate in 3.5% NaCl solutions to determine the opti-mum conditions for corrosion protection. The fatigue strength and hardness of the coatings were investigated. The experimental data indicated that the nanostructured coated samples exhibited higher hardness and fatigue strength compared to the conventional coated samples. On the other hand, the conventional coatings showed a better localized corrosion resistance than the nanostructured coatings.

Abstract: Background: Primary hyperhidrosis of the upper limbs is characterized by over activity of the eccrine sweat glands, primarily occurring on palmar, plantar and axillary regions. It is distressing and often socially disabling condition. Conservative treatment is usually not effective in controlling the disease mainly due to adverse effect of therapies. Endoscopic thoracic sympathectomy is considered as the treatment of choice, causing minimal morbidity and high success rates and patient satisfaction. Objective: The study aims to evaluate the long-term outcomes of single port bilateralthoracoscopic dorsal sympathectomyin treatment of primary hyperhidrosis of the palm and axilla. Methods: In this prospective study, performed primarily by a single surgeon, between August 1st 2010, and August 1st 2012, we performed 200 thoracoscopies on 100 patients with signs and symptoms of primary palmar and axillary hyperhidrosis in different age groups and in both genders, and all were studied and analyzed following treatment by single-port bilateral thoracoscopic dorsal sympathectomy in Sulaimani teaching hospital. Results: Total of 99 patients were satisfied with the outcome of post-surgery with a follow-up in the mean of 27 months and only one patient was reported no change in symptoms postoperatively. Complications reported in 6 patients inform of compensatory sweating (n = 2), Gestatory sweating (n = 1), Pneumothorax (n = 1), Intraoperative minor bleeding (n = 1) and only 1% failure rate was reported. No mortality was reported. Conclusions: Single port bilateral thoracoscopic thoracic sympathectomy is a very effective method in the management of primary hyperhidrosis. Single port provides less postoperative pain, safety, short operative time, and quick method for the treatment of primary hyperhidrosis in comparison to two or three ports approaches.
Application of the Improved Kudryashov Method to Solve the Fractional Nonlinear Partial Differential Equations  [PDF]
Md. Abdus Salam, Umme Habiba
Journal of Applied Mathematics and Physics (JAMP) , 2019, DOI: 10.4236/jamp.2019.74061
Abstract: Our purpose of this paper is to apply the improved Kudryashov method for solving various types of nonlinear fractional partial differential equations. As an application, the time-space fractional Korteweg-de Vries-Burger (KdV-Burger) equation is solved using this method and we get some new travelling wave solutions. To acquire our purpose a complex transformation has been also used to reduce nonlinear fractional partial differential equations to nonlinear ordinary differential equations of integer order, in the sense of the Jumarie’s modified Riemann-Liouville derivative. Afterwards, the improved Kudryashov method is implemented and we get our required reliable solutions where the results are justified by mathematical software Maple-13.
STUDENTS‘ FIRST IMPRESSION OF SECOND LIFE: A case from the United Arab Emirates
The Turkish Online Journal of Distance Education , 2011,
Abstract: Emerging 3D virtual worlds such as Second Life can offer students with opportunities to enhance learning using rich collaborative asynchronous media. Virtual worlds are believed to impact the future of higher education and therefore, universities across the world are immersing themselves inside virtual worlds to establish a unique learning and research environments. This research examines the viability of Second Life as an educational platform from the perspective of a group of students in an Islamic society context. The students were attending one of the universities in the United Arab Emirates. The analysis indicates that students experienced both positive and negative aspects of Second Life. The results do encourage further experimentation in this positive novel way for learning.
