In Wireless Sensor Networks (WSNs) lifetime of the system relies upon the vitality of the hubs, where vitality utilization is for the most part utilized for information transmission as opposed to detecting and preparing. A critical test in remote sensor systems is the ideal utilization of hub assets. Bunching of sensor hubs helps to utilize the hub vitality ideally and delay the lifetime of vitality compelled remote sensor arrange. Also, in WSN, the decision of steering convention assumes a significant job in using the vitality of hubs effectively. In this paper, another A2S LEACH (Active ↔Sleep - Low Energy Adaptive Clustering Hierarchy) directing strategy is proposed, which joins the two significant classes of various leveled conventions in particular bunch based methodology and chain based methodology. The proposed system is reproduced utilizing NS2 and the outcomes are examined. Reenactment results shows that the proposed A2S LEACH steering convention altogether diminishes vitality utilization and expands the all-out lifetime of the remote sensor organize when contrasted with the LEACH convention.
The paper deals with the awareness of information literacy among students of Arts and Science colleges in Tirunelveli. The objectives of the study is to identify the level of awareness of information literacy among students, to know the purpose of accessing library resources, to identify the search strategy tool used to access information, to know the level of usage of library resources, to identify the problem faced while accessing information and to know the level of satisfaction among students about their information literacy skills. This study deals with survey method and questionnaire tool was used for data collection. The research sample consists of both undergraduate and postgraduate students. The questionnaires were distributed randomly among the sample of 300 students in the selected three Arts and Science colleges in Tirunelveli. The collected data was analysed, interpreted and tabulated by using statistical tools like simple percentage and Pearson Moment Correlation Coefficient (PMCC) with the help of SPSS software. This study can used to know how to locate, access, and evaluate the right information in right time. It helps the librarian and faculty members to guide the students as where to access right source of information and how to evaluate their needed information and to satisfy the information users in an easy manner.
Aim: The present study was thus undertaken to analyze the genetic diversity of Kilakarsal and Vembur sheep breeds using single-nucleotide polymorphism (SNP) markers within Toll-like receptor (TLR) 3, 5, 6, 9, and 10 genes. Materials and Methods:Competitive allele-specific polymerase chain reaction (PCR)-based end-point genotyping was performed using real-time PCR to type the SNPs.Allele discrimination module implemented in real-time PCR was utilized to call the genotypes based on fluorescence intensity recorded for each of the two alleles.Basic diversity indices, namely, gene frequencies, observed heterozygosity, expected heterozygosity, and inbreeding coefficient (F IS ), and testing for Hardy-Weinberg equilibrium (HWE) were estimated using package for elementary analysis of SNP data software program.Results: Of the 25 SNPs, 22 were found to be polymorphic, whereas two SNPs, namely, TLR3_1081_AC and TLR9_2036_CT, were monomorphic in both Kilakarsal and Vembur sheep populations.The SNP TLR10_1180_AG was monomorphic in Kilakarsal but polymorphic in Vembur sheep.The observed heterozygosities were estimated as 0.289 and 0.309 in Kilakarsal and Vembur sheep, respectively, whereas the expected heterozygosity values were 0.305 and 0.309 in the two breeds, respectively.The overall mean F IS was 0.107 ranging from -0.005 to 0.241 in Kilakarsal sheep and -0.047 ranging from -0.005 to 0.255 in Vembur sheep.In Kilakarsal sheep, the test for HWE revealed TLR9_1308_GC SNP locus with significant deviation (p<0.05)due to heterozygosity deficit.In Vembur sheep, TLR10_82_CT and TLR10_292_CG loci showed significant deviation (p<0.05)due to heterozygosity excess.Other SNP loci did not deviate from HWE (p>0.05)revealing that the population was in HWE proportions. Conclusions:The SNP markers within five TLR genes (TLR3, TLR5, TLR6, TLR9, and TLR10) utilized for genotyping in this study were highly polymorphic in Kilakarsal and Vembur breeds of sheep.This study on the genetic diversity analysis of the Kilakarsal and Vembur sheep breeds revealed considerable genetic variation within the breeds and it can be utilized to improve desirable traits.
Book fairs play a great role in encouraging the reading habit among the people of all age groups. It is a basic and an imperative objective to make an educated society in this world. It shapes the identity of an individual and encourages them to build up the best possible reasoning techniques and making new thoughts. At display because the impact of the broad communications, individuals couldn't demonstrate much enthusiasm for perusing books, magazines and diaries, and so on, in this manner there is a need to build up the perusing propensities among the people in the general public. The present study investigates the reading habit among the public in a book festival at Tirunelveli. The purpose of this study is to know about the different aspects of reading habits of people through a book fair and opinions about the book fair at Tirunelveli. All the data obtained in the present study are presented in the form of tables for final interpretations.
