This paper presents a class of predictive estimators for two stage sampling with unequal first and second stage units to the case where information on auxiliary character is not available. A double sampling procedure is proposed as alternative under such a situation. The proposed class consists of mainly two estimators namely Ratio and Regression. The mean square error (MSE) and minimum mean square of this class have been derived. In addition, we support these theoretical results by an empirical study.Keywords

This paper investigates a two-unit cold standby system with different repair policies and imperfect coverage. There is a single server remains always with the system to do repair, recovery and replacement of the unit after imperfect coverage. The failure time of the unit is exponentially distributed while the distribution of repair times, replacement time and recovery time of the unit follows arbitrary distribution. The unit works as new after repair and preventive maintenance. All random variables are statistically independent. Switch devices are perfect. By using semi-Markov process and regenerative point technique we analyse various performance measures of system effectiveness. The behaviour of some important measures of system effectiveness has been observed numerically with respect to repair rate by giving particular values to other parameters.Keywords

The mass-production of antibiotics and medication has started an evolutionary race between antibiotics and bacteria. Pharmaceutical companies proved helpful to create new antibiotics, while pathogens developed a new level of resistance to these antibiotics. Growth of drug-resistant disease increases the challenge of searching for new, more effective antibiotics. The isolation and sequencing of cyclic peptide antibiotics is time-consuming and error-prone, compared with the linear peptides. Given these facts, there is a need for new tools to sequence cyclic non-ribosomal proteins (NRPs). In this paper we show how to improve the cyclic peptide sequencing method further to reduce its running time considerably in its expansion (branching) step. Our results suggest that instead of extending the k-mers over the full span of 18 to more than 100 amino acids, we could extend the k-mers just over the candidate amino acids measured in the first step of the cyclic peptide sequencing method. This strategy improves the running time and space requirement of the method significantly.

The success of in vitro fertilization (IVF), mammalian embryo culture and somatic cell nuclear transfer (SCNT) depend on stringent laboratory conditions and quality of chemicals, plastic ware, and glassware used to culture generated embryos. Therefore, all components and conditions need to be regularly monitored to avoid any kind of contamination and toxicity. Mineral oil (MO), a petroleum product, is extensively used to overlay the embryo cultures to maintain pH and osmolality of the culture medium. In human and farm animals, embryos are cultured with MO for 5 to 7 days to develop fertilized embryos to blastocyst stage1. Commercial suppliers claimed that MO is embryo safe by testing it with mouse embryo culture; however, MO quality can varied by a lot number and may deteriorate by improper storage and transport conditions. In addition, MO is an oil product that makes it susceptible to peroxidation and free radical formation2,3. Therefore, embryologist( s) should be more attentive to avoid MO-based embryo contamination and toxicity.Full Text

The electronic information resources have become the essential component of digital-era Library. These resources are indispensable in the present-day environment of rapid technology change. The present paper focuses on the use of e-resources in DAV College Libraries in Haryana by the students and faculty members for their learning, research, teaching and assignment purposes. This study evaluates the use of e-resources and satisfaction level with the e-resources by the users. The data has been collected using the questionnaire-based survey method. The paper also delineates how Libraries can prop up from these resources to improve the quality of work in rendering qualitative services to their users, consecutively saving time, energy and money as it is now the necessity of the hour.Keywords

The present study has been carried out on the availability of IT based facilities used by the staff and students of DAV College Libraries in Haryana. These facilities are a necessity in the technology friendly environment. IT provides major help to its users in organizing, processing, managing and retrieving the information and how to apply it in different thrust areas. With the introduction of new IT, Libraries redesigned their facilities to borderless world to support the society. Libraries use IT to manage housekeeping operations, communications, facilities and services and to provide better consistency in value added Library activities. It also assists Libraries in performing their operations and services most efficiently in a systematic way for rendering better and satisfying services to different user needs and to create an effective and intensive impact on all aspects of the present Library environment. This study evaluates various facilities and services rendered by the degree college libraries in Haryana State. For this purpose, the researcher has collected the data with the help of structured questionnaire. The data have been analyzed with the help of percentage and Chi-square test. Findings reveal that most of the IT based facilities are available in the libraries of DAV Colleges.Keywords
