This paper presents the organization structure of the Public Library System in Tamil Nadu, the first state in the Indian Republic, and brings out the growth of public libraries in Tamil Nadu after the approval of the library reorganization committee recommendations. Appraises the performance of the Public Library System in Tamil Nadu from 1975 to 2006. An analysis has been made about the nature and adequacy of the existing resources in the public library system in the state of Tamil Nadu, based on the analysis of the statistical data relating to public libraries and their use collected from the annual administration reports of the Directorate of Public Libraries, Government of Tamil Nadu. Based on the analysis and observationsa few suggestions are given for the development of public library system and services in India general and Tamil Nadu in particular.

This Study examines and explores through a web metric ranking analysis of the websites of 22 state universities in Tamil Nadu. It discussed the domain systems of the websites; WISER Web ranking for the year 2016 and 2017. Similarly, the researchers manipulated a new ranking tools for ranking the websites of State universities of Tamil Nadu, According to WISER ranking, Anna University is ranked first with 2469.4 WISER value followed by Tamil Nadu Agricultural University which is ranked second with 4031.4 WISER value. University of Madras is ranked third with 4333.8 WISER values in the year 2017. But when we used the PRIMOEX ranking, Anna University is ranked first with 3653.3 PRIMOEX value followed by Tamil Nadu Agricultural University which is ranked second with 4090.6 PRIMOEX value. Madurai Kamaraj University is ranked third with 4136.1 PRIMOEX values. Alagappa University is ranked fourth with 4956.1 PRIMOEX value and Alagappa University with 6001.9 PRIMOEX value is ranked fifth. It found that PRIMOEX good tool to measure the ranking of websites of state universities of Tamil Nadu.

Mealybugs (Hemiptera: Coccomorpha: Pseudococcidae) harbor diverse microbial symbionts that play essential roles in host physiology, ecology, and evolution. In this study we aimed to reveal microbial communities associated with two different mealybugs, papaya mealybug (Paracoccus marginatus) and two-tailed mealybug (Ferrisia virgata) collected from the same host plant. Comparative analysis of microbial communities associated with these mealybugs revealed differences that appear to stem from phylogenetic associations and different nutritional requirements. This first report on both bacterial and fungal communities associated with these mealybugs provides a preliminary insight on factors affecting the endomicrobial communities.

Information seeking behaviour is an activity of an individual in the process of identifying information that suits his/her knowledge pursuit. It is observed from the review of literature that there is no single study on the information seeking behaviour of faculties of pharmacy either at state level or national levels in India. Therefore this research has been conducted to bridge the gap on information seeking behaviour of pharmacy faculty in Tamil Nadu in view of the recent developments in information seeking behaviour, with objectives such as: to identify the information needs and seeking behaviour of faculty of the pharmacy educational institutions in Tamil Nadu (India); to examine the motivating factors for information seeking behaviour of the pharmacy faculty; to examine faculty opinions about the comprehensiveness or otherwise of respective institutions' library collections; and to analyse the extent of use and dependence on various sources of information for teaching and research. A total of 729 questionnaires have been distributed among 41 pharmacy educational institutions in Tamil Nadu, out of which 601 have responded, and the response rate is 82.44%. Based on the findings of the study certain implications have been derived as measures to enhance the quality of the pharmacy libraries in Tamil Nadu.

Information on forest type and cover density status of the present and past on large scale (1:50,000) is very much needed for conservation of any forest region. Such large-scale maps are not available for the Eastern Ghats (EG) of Tamil Nadu. This study deals with the preparation of forest type and cover density map of EG of Tamil Nadu during 2003 and the changes it has undergone between 1990 and 2003 using appropriate satellite data. About 10 forest types have been identified and mapped. Major changes have been observed in the forest types such as evergreen, and deciduous.

The methanolic crude leaf extract of Acacia melanoxylon shows inhibitory effects on seed germination, shoot growth, root growth and biomass of black gram (Phaseolus mungo L. Co 1) and weeds (Cassia occidentalis L. and Cyperus rotundus L.). The post emergence treatment was given on the 8th day after sowing and 4-6 days after seedling emergence. After postemergence treatment with 20% extract concentration, wilting symptoms appeared in P. mungo and C. occidentalis while necrosis occurred in C. rotundus. The seedling growth was inhibitory at all concentrations (5%, 10%, 20%) as compared to control plants. This inhibitory effect may be due to the presence of allelochemicals like phenolics in the A. melanoxylon leaves. Different types of phenolic acids were identified.

This paper aims to present a brief overview of consortia' initiatives that have been taking place at national and International level. The developed countries witnessed the progressive growth of consortia initiatives; on the other hand, the situation is not encouraging in developing countries like India. Therefore in this paper an attempt has been made to trace the current developments in consortia awareness in Engineering Educational Institutions. For this purpose, a survey of Engineering Educational Institutions in Tamil Nadu has been considered to measure the consortia awareness and also the attitude towards Joining any consortia. Based on the results of the survey a model consortium has been proposed for the Engineering Educational Institutions in Tamil Nadu.

Hexanal, a C-6 aldehyde has been implicated to have antimicrobial properties. Hence, this study was conducted to determine the antifungal activities of hexanal vapor against major postharvest pathogens of banana viz., Colletotrichum gloeosporioides and Lasiodiplodia theobromae. The pathogens were cultured in vitro and exposed to hexanal vapor at 600, 800, 1,000 and 1,200 ppm. Mycelial growth of both fungal pathogens were inhibited completely at 800 ppm and the incidence of anthracnose and stem-end rot diseases reduced by 75.2% and 80.2%, respectively. The activities of peroxidase, polyphenol oxidase, phenylalanine ammonia-lyase and glucanase had transiently increased in hexanal vapor treated banana by 5 to 7 days and declined thereafter. Postharvest treatment of banana with hexanal vapor resulted in phospholipase D inhibition and also resulted in cell wall thickening of the treated fruit, which impeded the penetration of the pathogenic spores. This was further confirmed by scanning electron micrographs. The defense-related protein intermediaries had increased in hexanal vapor treated banana fruit, which suggests induced resistance against C. gloeosporioides and L. theobromae, via., the phenylpropanoid pathway which plays a significant role in hindering the pathogen quiescence. Delayed ripening due to inhibition of phospholipase D enzyme, inhibition of mycelial growth and induced systemic resistance by defense enzymes collectively contributed to the postharvest disease reduction and extended shelf life of fruit.
