    While cloud computing is picking up prevalence, assorted security and protection issues are rising that block the quick reception of this new computing worldview. Furthermore, the improvement of cautious arrangements is lingering behind. To guarantee a safe and reliable cloud environment it is fundamental to distinguish the impediments of existing arrangements and imagine headings for future research. In this paper, we have reviewed basic security and protection challenges in cloud computing, arranged different existing arrangements, looked at their qualities and constraints, and imagined future research headings

    Background: Nosocomial infections are a major problem in both developed and developing countries. Among various reasons for the increase in the rate of nosocomial infections, the role of mobile phones used by Health Care Professionals (HCPs), is analyzed in this study. Aims and Objectives: To screen the surfaces of mobile phones of HCPs for pathogenic and nonpathogenic bacteria and to compare it with the control group. To study the significance of mobile phones of HCPs acting as vehicles for transmitting nosocomial infections. Materials and Methods: 200 HCPs (Doctors, nurses, medical students, and technicians) 50 other than HCPs mobile phone surfaces are swabbed with sterile swabs soaked in sterile saline and inoculated onto Blood agar and Mac Conkey agar and incubated for 48 hours. The organisms are identified by the colony morphology and characteristic biochemical reactions. Control group (50) comprised of general public and arts and science students. A questionnaire related to their habit of using the cell phones was also filled up by both the test group and the control group. Results: The pathogenic bacteria isolated from study group are Staphylococcus aureus, which is predominant, followed by E. coli, Klebsiella, Pseudomonas aeruginosa andProteus mirabilis. The non- pathogenic bacteria isolated are Micrococci, Coagulase Negative Staphylococci, Diphtheroids, Neisseria catarrahlis, Aerobic spore bearers, and Candida albicans. The prevalence of Pathogenic bacteria and Non Pathogenic bacteria are higher in HCPs samples when compared with the control group. KEY WORDS: Nosocomial infections; Mobile phones; Health care professionals

    Background: Abnormal uterine bleeding is most commonly encountered in 10-20% of women in reproductive age.  The objectives of the study are to assess the proportion and association with causes and postoperative outcome of preoperative anaemia and obesity in women with abnormal uterine bleeding who underwent hysterectomy.Methods: This was a retrospective observational record-based study conducted in the Dept. of Obstetrics and Gynaecology of Sri Manakula Vinayagar Medical College and Hospital(SMVMCH), Pondicherry. The study population consisted of 169 patients who were admitted for abnormal uterine bleeding and underwent hysterectomy from January 2016 to December 2016 for a period of one year.Results: The mean age was 43years.The mean value of haemoglobin on admission was 9.89g/dl. The distribution frequencies of patients by WHO BMI classification as underweight, normal, overweight and obesity are 8, 59, 78 and 24 respectively. The distribution frequencies of patients by WHO anaemia classification as no anaemia, mild, moderate are 34, 37 and 98 respectively. Seventy-six patients had blood transfusion. Six patients had urinary tract infection and all of them were anaemic and obese. Two patients had developed respiratory tract infection and none of the patients had developed deep vein thrombosis.  Conclusions: Preoperative anaemia was more common in patients with fibroid and associated with increased morbidity in immediate postoperative period. There is more prevalence of SSI among overweight and obese women

    Effects of the aqueous extracts of Rhodamnia cinerea on metabolic indices and sorbitol-related complications in Type 2 diabetic rats

    There is growing interest in the use of plant bioresources for managing Type 2 diabetes. In this study, Rhodamnia cinerea, which is used traditionally to manage diseases in Malaysia, was explored for its antidiabetic effects. Type 2 diabetic rats were managed for 4 weeks using aqueous extract of R. cinerea or quercetin. Weights and fasting glucose were measured weekly, while serum lipid profiles, insulin, antioxidant status, urea, creatinine and liver enzymes were assayed at the end. Sorbitol contents, antioxidant capacities and aldose reductase activities of the kidney, lens and sciatic nerve were also assessed. The results showed that the aqueous extract of R. Cinerea mainly contained Myricitrin and it reduced glycemia (p>0.05), lipid profiles (p<0.05), F2-isoprostanes (p<0.05) and overall metabolic condition of type 2 diabetic rats. R. cinerea also attenuated sorbitol contents of the nerve (p<0.05) and kidney (p<0.05), partly through regulating the activity of aldose reductase (p<0.05 for nerve) and sorbitol dehydrogenase (p<0.05 for kidney) in comparison with diabetic untreated group. Quercetin is a known aldose reductase inhibitor and can improve several metabolic indices related to Type 2 diabetes. In this study, the results of R. cinerea were comparable to or better than those of quercetin, suggesting that R. cinerea extract can be a good candidate for managing Type 2 diabetes and its complications related to sorbitol accumulation

    Numerical study of non-Newtonian polymeric boundary layer flow and heat transfer from a permeable horizontal isothermal cylinder

    In this article, we investigate the nonlinear steady state boundary layer flow and heat transfer of an incompressible Jeffery non-Newtonian fluid from a permeable horizontal isothermal cylinder. The transformed conservation equations are solved numerically subject to physically appropriate boundary conditions using a versatile, implicit, finite-difference technique. The numerical code is validated with previous studies. The influence of a number of emerging non-dimensional parameters, namely with Deborah number (De), surface suction parameter (S), Prandtl number (Pr), ratio of relaxation to retardation times (λ) and dimensionless tangential coordinate (ξ) on velocity and temperature evolution in the boundary layer regime are examined in detail. Furthermore, the effects of these parameters on surface heat transfer rate and local skin friction are also investigated. It is found that the velocity is reduced with increasing Deborah number whereas temperature is enhanced. Increasing λ enhances the velocity but reduces the temperature. The heat transfer rates is found to be depressed with increasing Deborah number, De, and enhanced with increasing λ. Local skin friction is found to be decreased with a rise in Deborah number whereas it is elevated with increasing values of relaxation to retardation time ratio (λ). Increasing suction decelerates the flow and cools the boundary layer i.e. reduces temperatures. With increasing tangential coordinate, the flow is also decelerated whereas the temperatures are enhanced. The simulation is relevant to polymer coating thermal processing. Polymeric enrobing flows are important in industrial manufacturing technology and process systems. Such flows are non-Newtonian. Motivated by such applications, we did the present problem
