                                                            Abstract

An ethnomedicinal plant, Pterolobium hexapetalum (Roth) Santapau & Wag (Leguminosae) was analyzed for antimicrobial activity. Bioassay of antimicrobial activity of hexane, chloroform and ethanol leaf extract showed significant activity against the human pathogens such as Proteus vulgaris, Pseudomonas aeruginosa causing urinary tract infections and septicaemia, Salmonella typhi causing typhoid fever, Vibrio species causing diarrheal infections and the fungus Candida albicans. The antimicrobial activity expressed the concentration-dependent against all the tested microorganisms.  Ethanol extracts exhibited the highest antimicrobial activity. The present findings provide an authentic scientific evidence for the traditional usages by various tribes in India. The bioactive compounds responsible for these antimicrobial activities against the tested microorganisms should be isolated and identified to develop a new lead of therapeutic interest.

DISTRIBUTED FILE SYSTEM

This paper describes Tidy FS, a simple and small distributed file system that provides the abstractions necessary for data parallel computations on clusters. In recent years there has been an explosion of interest in computing using clusters of commodity, shared nothing computers.Frequently the primary I/O workload for such clusters is generated by a distributed execution engine such as Map Reduce, or Dryad, and is high-throughput, sequential, and read-mostly. Other large-scale distributed file systems have emerged to meet these workloads, notably the Google File System (GFS) and the Hadoop Distributed File System (HDFS). Tidy FS differs from these earlier systems mostly by being simpler. The system avoids complex replication protocols and read/write code paths by exploiting properties of the workload such as the absence of concurrent writes to a file by multiple clients ,and the existence of end-to-end fault tolerance in the execution engine. We describe the design of Tidy FS and report some of our experiences operating the system over the past year for a community of a few dozen users. We note some advantages that stem from the system’s simplicity and also enumerate lessons learned from our design choices that point out areas for future development.

                                                     Abstract

A field experiment was carried out the pearl millet (Pennisetum americanum L., Leeke) in a mixture of garden soil, manure, and sand (1:1:1) to investigate the effects of supplementary calcium carbonate on plants grown at high NaCl concentration (50 mM). The treatments were: (i) control, (ii)NaCl treatment alone (50 mM); (iii) combined salt (50mM NaCl+10mM CaCo3). The plants grown under NaCl stress produced low fresh and dry weight and relative water content that those grown in control plants. Supplemental calcium carbonate added to NaCl treated plants significantly improved the growth and physiolocal differences affected by stress (e.g. plant growth, and membrane permeability) and also increase the K+ , Ca2+ , and N content in pearl millet. The effects of supplemental CaCO3 in maintaining membrane permeability, increase the content of  Ca2+ , N and K+  and reduce the content of Na+ in pearl millet crops production caused by high NaCl salinity.

Posted on by

Abstract

The development of the Internet during the past four decades had a profound impact on society in general, and on the field of library and information science in particular. This technology has involved processes, functions, services, media and information resources: the library as a whole. Its use has changed the fundamental roles, paradigms, and organizational culture of libraries and librarians. Today, library professionals are using it to provide library and information services to library clients. It is being used to provide access to electronic library collections, electronic reference services, electronic document delivery, and communicate with library users. Hundreds of discussion groups on various topics related to library and information work, electronic journals, and Web sites are also available on the Internet. Therefore, library professionals also have an opportunity to use the Internet for professional development and upgrading their skills.

STUDY OF SOCIAL INTELLIGENCE AND ACADEMIC ACHIEVEMENT OF THE PROFESSIONAL COLLEGE STUDENTS

Posted on by

Abstract

Education and social intelligence are interrelated since education is not a simple process of importing information, but it focuses on the development of personal and social qualities. Without the social and personal qualities man is incomplete. A truly educated person identifies himself as part of the society in which he lives, and makes good relations with others. Therefore, the nurturing process of social intelligence leads the academic success of the individuals. The study was carried out by Normative Survey Method under simple random sampling technique. The samples are drawn from the B,.Ed., Nursing and Medical Colleges located at Salem and Namakkal Districts of Tamilnadu, India. The sample consists of 377 professional college students studying final year course. Of them 152 were male and the rest 225were female. The results reveal that, the social intelligence of the college students are in the place of ‘average’ and their academic achievement is high. The ‘social leadership’ is higher and ‘social competency’ is lower. The college students differ in academic achievement and gender do not play any role in mean difference of their academic achievement.

Abstract

This study emphasizes the Locus of Control in school students and their progress in Academic Achievement in Zoology. The Locus of Control has a significant role on students’ lives, as their decisions and choices are related to their progress. Internal or external locus of control plays an important role for students to sustain the effectiveness and usefulness of learning performance. The knowledge and experience gained by the students by means of learning the content and the role of demographic factors is vital for increasing student’s performance. In this perspective, this study was carried out by Normative Survey Method. The samples were drawn from Salem Educational District under simple random sampling technique. The sample consists of 324 higher secondary studying students in the second year. Of them 117 were male and the rest 207 were female. The results reveal that the higher secondary students are high in overall locus of control and internal locus of control and above average in ‘academic achievement in zoology. They do not differ in ‘overall locus of control, internal and external locus of control and academic achievement in zoology’ with respect to gender and locality of the school. The students are possessing high relationship between the internal LOC and AAZ.
