Light-cone gravity in AdS
We obtain a closed form expression for the Action describing pure gravity, in
light-cone gauge, in a four-dimensional Anti de Sitter background. We perform a
perturbative expansion of this closed form result to extract the cubic
interaction vertex in this gauge.Comment: 11 page
Performance of Regional Rural Banks after Amalgamation in India: Progress and Prospects
For the past three decades India's banking system has several outstanding achievements to its credit. The most striking is its extensive reach. It is no longer confined to only metropolitans or cosmopolitans in India. In fact, Indian banking system has reached even to the remote corners of the country. This is one of the main reasons for India's growth process. The government's regular policy for Indian banks since 1969 has paid rich dividends with the nationalization of 14 major private banks of India. Regional Rural Banks started their development process on 2 October 1975 with the formation of a single bank—Prathama Grameen Bank. The RRBs mobilize financial resources from rural/semi-urban areas and grant loans and advances mostly to small and marginal farmers, agricultural labourers and rural artisans. The area of operation of RRBs is limited to the area as notified by GoI covering one or more districts in the State. In this context, the present study is an attempt to examine the impact of amalgamation on physical performance of RRBs during post-amalgamation period
A conceptual study on Cosmetic Toxicity w.s.r. to Dushi Visha
In present state thousands of hurtful toxins are accumulated in environment are taken by the human being itself. Cosmetics are one of them. Cosmetics are those elements which are used to improve the appearance of the human body. They are generally combinations of chemical compounds, some being derived from natural sources, many being synthetic. But the people are not aware of adverse effects of these chemical substances on human body due to its long-term usage. Therefore, this study was carried out which was conceptual type in nature. The aim & objectives of this study was to study the concept Dushivisha & to study the toxic effects of cosmetics on human body & correlate the Dushivisha w.s.r. cumulative toxicity of cosmetics. All the relevant material was compiled from Brihatrayi and available commentaries on it. Research articles are also searched from various websites. All the references were collected & analyzed & finally conclusion was drawn. Conclusion of this study is that cosmetics can be included under cumulative type of toxicity. Due to cumulative toxicity hazards of this substance not seen on the body immediately but they can be seen slowly after their long-term use. This cumulative type of toxicity is similar to Dushivisha concept described by Ayurveda
Wound Healing Activity of Calotropis Procera Root Bark on Diabetic Rats
Herbal therapy and herbal medicine in traditional medicine as well as in alternative medicine practiced in the developed world. There is recent most of the harbal formulation are used to cure & improve the humal life. The present study Wound healing activity of Calotropis procera root bark on diabetic rats in that root bark is extracted from ethanolic extract using soxhlet method. The pharmacognostic study was done after that phytochemical characters should be studied. The root bark has alkaloids, Flavonoids, steroids and tannins active constituents. Acute toxicity study carried out with three pharmacological models Incision model, Excision model, and Dead space model. All the extract show predominant activity against selected species. Extract shows beneficial effect on diabetic wound it heals in time with standard component. Overall results of this study reveals that this is an effective extract on diabetic wound.

Salient Features Selection Techniques for Instruction Detection in Mobile Ad Hoc Networks
The development of wireless mobile ad hoc networks offers the promise of flexibility, low cost solution for the area where there is difficulties for infrastructure network. A key attraction of this mode of communication is their ease of deployment and operation. However, having a good and robust mobile ad hoc networking will depend entirely on security mechanism system in place. Traditional security mechanisms know as firewalls were used for defensive approach to oppose security obstacle. However, firewalls do not fully or completely defeat intrusions. To cope with this limitation, various intrusions detection systems (IDSs) have been proposed to detect such network intrusion activities. The problem encounter for this particular technique of instruction detections technique is that during network monitoring for data collection for anomaly detection, data that does not contribute to detection must be deleted before detection can be processed or application of learning algorithm for detection of abnormal attacks. In this paper we present a novel feature technique for feature selection before learning technique should be applied. The method has been applied into our own data set, and for the detection purpose we have used most of the well reputed three Machine Learning classifiers with the new selected features for performance evaluation and the experiment shows that higher accuracy results could be achieved with only all the 9 features extracted with our own algorithm with the data set created by using RandomForest classifier
State of malaria diagnostic testing at clinical laboratories in the United States, 2010: a nationwide survey
<p>Abstract</p> <p>Background</p> <p>The diagnosis of malaria can be difficult in non-endemic areas, such as the United States, and delays in diagnosis and errors in treatment occur too often.</p> <p>Methods</p> <p>A nationwide survey of laboratories in the United States and its nine dependent territories was conducted in 2010 to determine factors that may contribute to shortcomings in the diagnosis of malaria. This survey explored the availability of malaria diagnostic tests, techniques used, and reporting practices.</p> <p>Results</p> <p>The survey was completed by 201 participants. Ninety percent reported that their laboratories had at least one type of malaria diagnostic test available on-site. Nearly all of the respondents' laboratories performed thick and thin smears on-site; approximately 50% had access to molecular testing; and only 17% had access to rapid diagnostic tests on-site. Seventy-three percent reported fewer than five confirmed cases of malaria in their laboratory during the 12-month period preceding the survey. Twenty-eight percent stated that results of species identification took more than 24 hours to report. Only five of 149 respondents that performed testing 24 hours a day, 7 days a week complied with all of the Clinical and Laboratory Standards Institute (CLSI) guidelines for analysis and reporting of results.</p> <p>Conclusion</p> <p>Although malaria diagnostic testing services were available to a majority of U.S. laboratories surveyed, very few were in complete compliance with all of the CLSI guidelines for analysis and reporting of results, and most respondents reported very few cases of malaria annually. Laboratories' difficulty in adhering to the rigorous CLSI guidelines and their personnel's lack of practice and proficiency may account for delays and errors in diagnosis. It is recommended that laboratories that infrequently process samples for malaria seek opportunities for practice and proficiency training annually and take advantage of available resources to assist in species identification.</p
A BRIEF REVIEW ON PROCESS ANALYTICAL TECHNOLOGY (PAT)
Process analytical technology (PAT) has been defined as a mechanism to design, analyze and control pharmaceutical manufacturing processes through measurement of critical process parameters which affect critical quality attributes. PAT checks the quality of raw material attributes both physically and chemically (i.e. at off-line, on-line, in-line). PAT involves a shift from testing the quality of building to the quality of products by testing at several intermediate steps. PAT saves a huge amount of time and money required for sampling and analysis of products. The main goal of PAT is to provide successful tools such as multivariate data analysis and acquisition tools, modern process analyzers or analytical chemistry, endpoint process monitoring, controlling tools and continuous improvement and knowledge improvement tools. In this review attempt has been carried out to explore the concept of PAT, different tools of PAT, goals of PAT, How it Works and Its benefits
