Cerium-based conversion coatings were formed on AZ91D magnesium alloy by immersion of the substrate in solutions containing Ce(NO_(3))_(3),H_(2)O_(2) and ascorbic acid(HAsc).The characterisation of the films was performed by electrochemical and surface analysis techniques such as SEm,EDS,X-ray diffraction and X-ray photoelectron spectroscopy(XPS).The degree of corrosion protection achieved was evaluated in simulated physiological solution by the open circuit potential monitoring,polarisation techniques and electrochemical impedance spectroscopy(EIS).The presence of HAsc in the conversion solution causes changes in the morphology,adherence and anticorrosive performance of the *** improvement in the corrosion resistance is closely associated with the corrosion inhibition properties of HAsc.

Objective: The study aims to explore the prevalence of hypertension and its impact on Type 2 diabetes in a mysore population of the Indian subcontinent. methods: 636 participants volunteered for the study. Anthropometric measurements and blood pressure were recorded while plasma was analyzed for biochemical markers. The IDF and jNC 7 diagnostic criteria were followed to define diabetes and hypertension. Statistical Analyses: One-way analysis of variance, χ2-test and Logistic regression analysis were performed to assess differences of the mean, proportion and the independent effect of hypertension on the development of type 2 diabetes. Results: Hypertension was observed to be prevalent in 37.1% of the studied population with an insignificant gender difference. Rate of occurrence of hypertensives was found to be significantly higher in type 2 diabetes (51.9%), obese subjects (45.2%), long-term smokers (49%) and alcohol addicts (48%) than control groups. The risk of development of diabetes was significantly higher in hypertensives than normotensive. However, when creatinine and blood urea nitrogen were included in the model, the significance was nullified. Conclusions: The prevalence of type 2 diabetes and hypertension is increasing at an alarming rate. This study reveals that the significance of hypertension as a parameter in predicting the risk of type 2 diabetes was influenced by the renal function and lipid profile.

magnesium and aluminum alloys continually attract interest as lightweight structural materials for transport applications. However, joining these dissimilar alloys is very challenging. The main obstacle that hinders progress in dissimilar mg-Al joining is the formation of brittle intermetallic compounds(ImCs). As a solid-state joining technique, FSW is an excellent candidate to attenuate the deleterious ImC effects in dissimilar Al-mg joining due to the inherent low heat inputs involved in the process. However, the ImCs, namely Al_(3)mg_(2) and Al_(12)mg_(17) phases, have also been reported to form during Al-mg dissimilar FSW;their amount and thickness depend on the heat input involved;thus,the weld parameters used. Since the heat dissipated in the material during the welding process significantly affects the amount of ImCs,the heat input during FSW should be kept as low as possible to control and reduce the amount of ImCs. This review aims to critically discuss and evaluate the studies conducted in the dissimilar Al/mg FSW through a scientometric analysis and also with a focus on the strategies recently applied to enhance joint quality. The scientometric analysis showed that the main research directions in mg/Al FSW are the technological weldability of aluminum and magnesium during FSW, structural morphology, and mechanical properties of dissimilar welded joints. Considering the scope of application of the aforementioned joints, the low share of articles dealing with environmental degradation and operational cracking is surprising. This might be attributed to the need for well-developed strategies for obtaining high-quality and sustainable joints for applications. Thus, the second part of this review is conventional, focusing mainly on the new strategies for obtaining high-quality mg/Al joints. It can be concluded that in addition to the necessity to optimum welding parameters to suppress the excessive heat to limit the amount and thickness of ImC formed and improv

Agroforestry and beekeeping are widely promoted as prospective Nature- Based Income Generating Activities (NIGAs) to improve livelihoods while at the same time enhancing biodiversity conservation in degrading agro-ecologies. These activities can diversify and increase famers’ incomes and support instinctive biota and fauna resilience. However, evidence to showcase and compare their long-term benefits is scant. We use the case of Uluguru Mountains in Tanzania to evaluate and compare viability of agroforestry and beekeeping projects using the Cost Benefit Analysis (CBA) approach. The results of analysis yielded positive NPVs for both agroforestry and beekeeping projects at discount rates not higher than 8.2% and 8.5% respectively. Overall, the comparison of economic viability between agroforestry and beekeeping projects revealed that the former was relatively more profitable than the later in terms of both the NPV and Benefit Cost Ratio (BCR) criteria. However, the Internal Rate of Return (IRR) for beekeeping was slightly higher than that of agroforestry. Yet, we underscore the fact that these two projects can jointly be implemented to enhance livelihoods of farmers and support biodiversity conservation in the study mily:Verdana;">

· AIm: To describe and analyze the demographic characteristics and to determine the angiographic features of acute central serous chorioretinopathy(CSCR) in an Egyptian population. ·mETHODS: A series of consecutive patients presenting with acute idiopathic CSCR to mansoura Ophthalmology Center mansoura University who underwent fluorescein angiography (FA) within a 3 -year -period (between january 1, 2007 and December 31, 2009) was retrospectively studied. Patient demographics and angiographic features were studied. Results were compared to those of other Western and Asian populations. ·RESULTS: Fluorescein angiograms of 86 patients were analyzed. 91% were males. The age range of patients was 24 -49 years, with a mean age of (38±6) years. The right eye was the presenting eye in 47% of patients. Eighty seven percent of eyes showed delayed choroidal filling. Thirty -five percent of patients had more than one point of leakage. The macula was the most common site of fluorescein leakage seen in 79% of patients. Peripheral leakage was seen in 14% of patients while peripapillary leakage was seen in 12% of patients. The inkblot leakage pattern was found in 53% of patients. The presenting eye had RPE atrophic changes in 84% of cases. The other eye was assessed in 44 patients (51%). Fifty-five percent of them had signs of RPE atrophic changes. ·CONCLUSION: In the Egyptian population, CSCR is seen at younger age with higher male -to -female ratio and more frequent smokestack leaks than other populations. Despite younger age group, this series of patient showed higher frequency of bilateral and multifocal disease compared to other studies. Roles of psychological stress and choroidal ischemia in pathogenesis of CSCR need further evaluation. ·
