FORMULATION AND EVALUATION OF LACTIC ACID BACILLUS AND ZINC SULPHATE FAST DISPERSIBLE TABLETS
Srikanth CH,Subal Debnath,Shireesh Kiran R,Raja shekhar S
Journal of Drug Delivery and Therapeutics , 2012,
Abstract: The aim of the present work is to formulate fast dispersible tablets of lactic acid bacillus & Zinc sulphate. In this study, different formulations of fast dispersible tablets were prepared using various excipients & super disintegrants. Different concentrations of crospovidone, cross carmellose sodium & sodium starch glycolate were used as super disintegrants in the formulation of fast dissolution tablet. The powder mass was evaluated for flow properties. All these formulations were prepared by wet granulation method. The tablets were evaluated for hardness, thickness, weight variation, friability, wetting time, disintegration time, and water absorption ratio. Tablets containing crospovidone showed shorter disintegration time i.e. less than 30 sec, comparaed to cross carmellose sodium & sodium starch glycolate hence better patient compliance & effective therapy.
X-ray absorption (XANES) and photoelectron spectroscopy (XPS) of gamma irradiated Nd doped phosphate glass
V. N. Rai,Parasmani Rajput,S. N. Jha,D. Bhattacharya,B. N. Raja Shekhar
Physics , 2015,
Abstract: This paper presents the X-ray absorption near edge structure (XANES) and X-ray photoelectron spectroscopic (XPS) studies of Nd doped phosphate glasses before and after gamma irradiation. The intensity and location of LIII edge white line peak of Nd are found to be dependent on the concentration of Nd as well as on the ratio of O/Nd in the glass matrix. The decrease in the peak intensity of white line of XANES spectra and asymmetry in the profile of Nd 3d5/2 peak of XPS after gamma irradiation clearly indicates that Nd3+ gets reduced to Nd2+ in the glass matrix, which increases with an increase in the doses of irradiation. Sharpening of Nd 3d5/2 XPS profile indicates about the deficiency of oxygen in the glass after gamma irradiation, which is supported by EDX measurement.
Measuring Quality of Service in Retail Outlets Using Fuzzy Numbers
P. K. Mishra,B. Raja Shekhar
Management Science and Engineering , 2010,
Abstract: The measurement of quality of service in any service providing organisation has been a very complex process to deal with. Most of the attributes here are intangible; largely depend upon customers’ expectations and perceptions. The quality of service may be poor, average, good, and so on depending upon the performance of the service provider. The linguistic terms like poor, average and good could be vague (fuzzy) unless various attributes of a particular service are understood precisely. In order to avoid the ambiguity of the concept associated with customers’ expectations and perceptions of service quality fuzzy numbers are widely used in many complex management issues. In this paper we focus on quantifying the quality of service in retail outlets based on some specific characteristics using fuzzy numbers. Key words: Quality of service; Retail outlets; linguistic terms; fuzzy numbers
Impact of Service Quality Management (SQM) Practices on Indian Railways - A Study of South Central Railways
M. Devi Prasad,B. Raja Shekhar
International Journal of Business and Management , 2010, DOI: 10.5539/ijbm.v5n9p139
Abstract: The main objective of this study is to present a framework developed for assisting Railways to monitor and control the quality of services provided to passengers. The study evaluated the passenger Rail Service quality of Indian Railways by developing SQM (Service Quality Management) model on the basis of SERVQUAL and Rail Transport quality. Three new dimensions (Service Product, Social Responsibility and service delivery) are added to the original five SERVQUAL dimensions (i.e. assurance, empathy, reliability, responsiveness and tangibles). The instrument is tested for reliability and validity. Empirical study was conducted at Secunderabad Railway station of South Central Railway, India, using a purposive sample of 200 respondents. Valid responses from the questionnaire are statistically analyzed by using factor analysis. This research has also identified the order of importance for these eight factors, for example service delivery and social responsibility are identified as the most important and the least important factors respectively. This study would help the Railways to monitor, control and improve the service.
Impact of Risks and Uncertainties on Supply Chain: A Dairy Industry Perspective
PRAMOD KUMAR MISHRA,RAJA SHEKHAR B
Journal of Management Research , 2011, DOI: 10.5296/jmr.v3i2.651
Abstract: No business organisation is out of purview of risks and uncertainties and hence the dairy industry is no deviation. Dairy industry which plays a crucial role in agro-based economy of a country provides enough scope to the rural and sub-urban people to earn extra money in their leisure time. The industry is extended from a milk producer in the rural area to a consumer in the urban area through some of the core processes like pasteurisation and transportation. The dairy food supply chain which entangles several stakeholders in the system gets disrupted many a times due to various vulnerabilities in the operation. The vulnerabilities in terms of risks and uncertainties get multiplied with the perishability nature of the raw material that is milk which the industry deals in. The study will discuss about the various risks and uncertainties from a dairy industry perspective and their impact at various stages of the supply chain.

Udaya Bhaskar Nallamalli,B.Raja Shekhar
Journal of Management Research , 2011, DOI: 10.5296/jmr.v3i2.674
Abstract: The Indian Retail Industry is witnessing a rapid transformation and is the fastest growing sector contributing 10 percent of the country’s GDP. Indian retail market is estimated to grow from $427 billion in 2010 and is expected to reach $637 billion by 2015 (Srivastava 2008). India became the prime destination for the global retailers because of favorable demographics, high disposable income levels, changing life styles and increased customer awareness. Indian apparel retailing is the country’s largest opportunity for the organized retailers after food retailing. The fast pace of the Indian retail industry presents many companies with a host of daily challenges. In today’s competitive environment and with the growing importance of services, delivering high quality services has become the basic retailing strategy. The present paper studies the impact of service quality on apparel retail customer satisfaction and also indentifies the critical factors of service quality from customer’s perspective. The sample consists of 250 respondents from the Metropolitan City Hyderabad which is one of the fastest growing metropolitan cities in India a structured questionnaire RSQS (Retail Service Quality Scale) was administered for data collection. Secondary data was collected from research databases, reports, journal articles etc. SPSS 17.0 was used for statistical analysis. The results will help the Retail service managers to plan and design their service strategies. The study identifies the critical of factors of Apparel Retail Service Quality and evaluates the impact of service quality on Retail Customer Satisfaction. The results helps the retailers to focus on critical areas of service where to improve, where to modify and where to cut down and enables them to take effective service strategies.
Fast Digital Convolutions using Bit-Shifts
Shekhar S. Chandra
Computer Science , 2010,
Abstract: An exact, one-to-one transform is presented that not only allows digital circular convolutions, but is free from multiplications and quantisation errors for transform lengths of arbitrary powers of two. The transform is analogous to the Discrete Fourier Transform, with the canonical harmonics replaced by a set of cyclic integers computed using only bit-shifts and additions modulo a prime number. The prime number may be selected to occupy contemporary word sizes or to be very large for cryptographic or data hiding applications. The transform is an extension of the Rader Transforms via Carmichael's Theorem. These properties allow for exact convolutions that are impervious to numerical overflow and to utilise Fast Fourier Transform algorithms.
Testosterone and Its Analogs as a Male Contraceptive  [PDF]
Abdul S. Ansari, Chandra Shekhar Yadav, Nirmal K. Lohiya
Advances in Sexual Medicine (ASM) , 2013, DOI: 10.4236/asm.2013.33A002
Abstract: Male contraception by means of hormonal approach was initiated more than 60 years ago when men became azoospermic with administration of testosterone. The basic principle of male hormonal contraception is suppression of spermatogenesis. Exogenous testosterone/testosterone analogs alone or in combination with progestin have been tested for contraceptive efficacy by inhibiting gonadotropins release from pituitary gland. In this review article, advancement in different testosterone preparation tested alone or in combination for contraceptive efficacy has been focused. Administration of testosterone or testosterone analogs alone failed to provide uniform azoospermia or severe oligospermia (<1 million/ml sperm count) at lower doses regimens whereas higher doses causes side effects. Newer, androgen-progestin combination has proved better contraceptive efficacy than testosterone alone. Further, long term studies with hormonal regimens and other alternative approaches are required with fewer side effects for development of safe and reversible contraceptive.

Drug-Induced Hemolytic Anemia: A Fatal Complication Further Under-Recognized in Sickle Cell Disease  [PDF]
Monica Khurana, Shekhar S. Raj
Open Journal of Blood Diseases (OJBD) , 2017, DOI: 10.4236/ojbd.2017.73008
Abstract:
Drug-induced immune hemolytic anemia (DIIHA) is commonly attributed to cephalosporins. Ceftriaxone is the most frequently administered cephalosporin in patients with sickle cell disease. We present a pediatric patient with severe DIIHA (hemoglobin < 2 g/dl) who survived. Since DIIHA often goes undiagnosed until late in the course, vigilance of DIIHA minimizes unnecessary diagnostic tests and therapies. DIIHA likely remains under-recognized in all patient subpopulations due to its rarity and overlapping presentations with other conditions. Distinction between exacerbation of chronic hemolysis and new onset of acute hemolysis poses a unique challenge in patients with sickle cell disease. A thorough analysis is warranted to better identify factors within the pediatric sickle cell population that may increase the predisposition for DIIHA, particularly due to ceftriaxone.
