Antimicrobial control programs are widely used to decrease antibiotic utilization, but effects on antimicrobial resistance and outcomes for patients remain controversial. The purpose of this study was to determine the impact of rotation of antibiotic classes used as empirical surgical prophylaxis on the emergence of bacterial resistance organisms and antibiotics drug use when compared with non-rotation period. Three core, broad spectrum agents (Cephalosporins, beta-lactam-inhibitors, and fluoroquinolones) were selected for inclusion in the quaternary rotation for 21 months, based on prior 8 months baseline data from GIT and urology surgical wards in Ibn Sina hospital. Intensive surveillance done for patients admitted to the selected settings. 1681 surveillance samples obtained from 2359 eligible inpatients admitted to hospital from Jan 2008 to May 2010. A significant reduction in the percentage of positive growth had been observed with antibiotic rotation for both wards from 65% and 49% in baseline to 59% and 33% in rotation (1) and 25% and 33% in rotation (2) in GIT and urology ward respectively (p? 0.0001). As general there was a divergent effect of the antimicrobial rotation on the prevalence of resistance among G+ve and G-ve bacteria. We concluded that antimicrobial drug use in surgical departments could be optimized after implementation of antimicrobial cycling policy, and associated in reduction in the incidence of infectious mortality and morbidity but stabilize antibiotic resistance, without significant reduction.

Exhaust of simple, reheat and inter-cooling cycle of gas turbine cycle posses a lot of energy. Sometime this energy is so much that it can run another cycle or it can be used to heat the compressed air from the compressor to the combustion charmer that results to increase the overall efficiency of the plant. Air Bottoming Cycle (ABC) was proposed as an alternative for the conventional steam bottoming cycle. In spite of the cost of reducing hardware installations it could achieve a thermal efficiency of 80%. This paper is the parametric analysis of regenerative ABC Combine Cycle. The variables are compression ratio of topping cycle, peak temperature of the combustion chamber and mass flow rate of bottoming cycle. The result shows the gain in net work output as well as efficiency of combined cycle is 14% to 33%.

The research study was design to measure the participants’ satisfaction with continuous professional development (CPD) program. Study also aims to explore the affects of demographic factors that can enhance or decrease the satisfaction level of the course participants. For the measurement of participants’ satisfaction quantitative and qualitative methods were used. For quanttative analysis a research tool comprised of 73 items were developed and for qualitative analysis interview method was used. The population of the study includes primary school teachers, head teachers and DTE’s. Cluster training and support center, district teacher educator and primary school teachers asked to response about continuous professional development program through the questionnaire and interview. Total number of sample was 66 PST’s, head teachers and DTE’s. The data collected through the questionnaires was analyzed with the help of statistical package for social sciences. Results reveled that overall teachers with less experience and professional qualification are more satisfied with this training; Moreover female teachers are more satisfied as compared to male participants.

Growing public interest and awareness of environmental issues have contributed to the global spread of pay-as-you-throw (PAYT) schemes, highlighting their effectiveness in promoting cultural change toward more responsible and sustainable consumption practices. The objective of this paper, after a systematic review of the literature, is to analyze the system, methods, and calculation of point-based taxation, focusing on the benefits: from the point of view of environmental sustainability, the application of the point-based tariff leads to a reduction in waste, while increasing sorting and recycling; from the point of view of local finances, this could reduce the costs of waste management services, through more efficient use of public resources.After outlining trends in using the PAYT system in Italian municipalities over the past five years, we focus on implementation in Benevento, a medium-sized city in southern Italy. Introducing this system involves several significant investments, funds for which can be raised from Recovery and Resilience Plan funds and through a complex administrative process.

And responsibilities should be assigned to the right people who have access to the right information concerning retirees.

A multiband slotted and defected ground microstrip patch antenna which operates at more than one frequency has been designed. It effectively tunes at 3GHz, 5.5GHz and 7.8GHz with satisfactory return loss obtained at these resonant frequencies, which is -10.72dB, -13.38dB and -14.55dB respectively. Size of the antenna is going to be compact. The substrate FR4 epoxy (relative permittivity: 4.4) is used in the design of the antenna. Antenna design is proposed in different type of slots such as T-shaped and rectangular-shaped etc. slots in patch. This design can be used for wide range of Wireless applications. For the simulation HFSS is used.

The study evaluates the performance and risk of monthly income plans of selected mutual funds with an objective to identify the top performing monthly income plan amongst the selected plans. The study has analyzed growth performance on the basis of returns of 6 months, 1 year, 3 years and since inception returns. Growth performance of the funds have been compared with industry average, and its benchmark index i.e., CRISIL MIP Blended Index. The Standard Deviations, Sharpe Ratio and Beta of the selected schemes have been compared to analyze volatility of the schemes and return per unit of risk. The study ends up with identifying top performing monthly income plans for relatively aggressive and conservative risk profile investors.

Peritoneal pseudomyxoma, sometimes called a gelatinous disease of the peritoneum or gelatinous ascites of the peritoneum, is a rare disease. Peritoneal pseudomyxoma is defined by the presence of extracellular mucin in the peritoneal cavity. The objective of our work is to study, through a case of pseudomyxomeperitoneal and a review of the literature, the semiological, diagnostic and therapeutic features of this pathology.

Pharmacovigilance is an important and integral part of clinical research. Pharmacovigilance is defined as the pharmacological science relating to the detection, assessment, understanding and prevention of adverse effects, particularly long term and short term adverse effects of medicines. Pharmacovigilance will certainly help identifying risks and risk factors in the shortest possible time so that harm can be avoided or minimised. Pharmacovigilance is the science and activities relating to detection, assessment, understanding and prevention of adverse effects or any other possible medicine related problem. Today its importance cannot be sidelined at all, given the number of new medicines being introduced in the market.

The use of a latent heat storage system using Phase Change Materials (PCM) is an effective way of storing thermal energy (solar energy, off-peak electricity, industrial waste heat) and has the advantages of high storage density and the isothermal nature of the storage process. In the present era the utilizations of electricity and other conventional modes are quite in effective to the present demand and in other hand the role of alternative energy resources which compensates the present energy demands of the world will be not enough for the future. Meanwhile by the year 2020 the renewable energy resources are depleting so that it will become in need of very high energy demand due to over population in India comparing to the world resources and their populations. Now it clearly shows that trapping the solar energy and storing the heat by means of suitable PCMs will give other hand support to solve the energy crisis will help to bring out a new milestone in energy storage revolutions. It has been demonstrated that, for the development of a latent heat storage system, choice of the PCM plays an important role in addition to heat transfer mechanism. The information on the latent heat storage materials and systems is enormous and published widely in the literatures. In this paper, an attempt has been made to provide information from the previous works on PCMs and latent heat storage systems. This review may have been planned to be useful to the scientists and researchers to investigate more on PCMs.
