Occurrence of 19 weeds (18 angiospermic and 1 pteridophytic weed) was observed in the paddy fields of Sivagangai district in Tamil Nadu. The weeds are consumed as vegetables by the local people. During present study, botanical names of the weeds along with their families, vernacular names, mode of consumption and utilities as food have been documented.Keywords

This study examines the quality assurance in services provided by Arjun Singh Central Library, Periyar Maniammai University, Thanjavur, Tamilnadu. A well structured 125questionnaires were distributed among the library users to find the qualitative services provided by the university library. The questionnaires were checked and out of 115 filled-in questionnaires returned 108(93.98%) were found fit for analysis and out of which 7(6.08%) were considered unusable. The present study demonstrates and elaborates the various aspects of use of information resources and services, physical facilities available and collection of Central Library, Periyar Maniammai University, Thanjavur. It identifies the levels of use of various services provided, and highlights problems faced by the users and satisfaction level of users with the central library collection. Suggestions have been given to make the service more beneficial for the academic community of the university.Keywords

The present investigation reveals standardization which includes moisture content, total ash, acid insoluble ash, water soluble extractive value and loss on drying of Alocasia sanderiana W.Bull ethanolic leaf, stem and ischolar_main tuber extracts. Total ash value is useful in determining authenticity and purity of drug and also these values are important quantitative standards. Total ash value of plant material indicated the amount of minerals, and earthy materials present in the plant material. Analytical results showed the total ash higher value was 3.30% w/w in ethanolic ischolar_main tuber extract of Alocasia sanderiana. Percent weight loss on drying or moisture content of ethanolic leaf, stem and ischolar_main tubers extracts is 63.69%, 73.35% and 75.63%. The less value of moisture content could prevent bacterial, fungal or yeast growth. Leaf ethanolic extracts having less value compared stem and ischolar_main tuber extracts. Ethanolic leaf extracts shows more antimicrobial activity. The higher amount of acid-insoluble siliceous matter present in the tuber extracts of A. sanderiana was 0.95w/w%. The water-soluble extractive value indicated the presence of sugar, acids, and inorganic compounds. The ethanolic ischolar_main tuber extract have higher value of water soluble extractive values.Keywords

During cross flow in a heat exchanger, heat transfer in the front portion of the tube is more compared to back portion of the tube. This is due to less formation of vortices at the backside of the tube. For uniform heat transfer to take place throughout the tube, it is necessary to increase the vortex formation at the rear side of the tube. The aim of this study is to explore the possibilities of improving the flow structure and thereby increasing uniform heat transfer around the tubes by introducing special type of fin arrangement over the tubes. The effect of shape and orientation of the fin on vortex generation and respective heat transfers are studied numerically. It have been identified that by introducing special type of fin arrangement over the tube there is a possibility for increase the vortex formation at the rear portion of the tube, which significantly leads to creation of uniform heat transfer all around the tube.Keywords
