       The work focused on concrete mixes having a fixed water/cement ratio. In the present experimental programme an attempt has been made to investigate the possibility of reusing one of these locally available rural waste fibrous material, coir in concrete. Since the material used in this study is locally available rural fibre, a detailed characterization is planned. A concrete mix has been designed to achieve the minimum grade of M30 as required by IS 456 – 2000. The investigation contains, to identify the effects on workability and mechanical strength properties due to the addition of coir fibre, workability tests such slump and the mechanical strength tests on standard specimens such as compressive strength, split tensile strength and flexural strength were conducted on the coir fibrous concrete specimens. Totally 36 cubes,36 cylinders and 36 flexure specimens were cast and tested. Based on the experimental results of workability and mechanical strength studies, a constant length of 50 mm and three trials such as 0.2% , 0.5% and 1% (volume of coir fibre) are chosen for further studies. By analyzing the results, it is concluded that marginal improvements in the mechanical strength properties are observed.

They are known to be highly toxic to cells, mainly through their action on cell reproduction. Many have proved to be carcinogens, mutagens or teratogens. Patients receiving therapeutic doses of these drugs have exhibited many adverse effects, including cancers. All people who came in contact with cytotoxic drug...

Student, Dept. of Home Science, University of Rajasthan, Jaipur, Rajasthan, India Kesar Chayal  Assistant Professor, Dept. of Home Science, University of Rajasthan, Jaipur, Rajasthan, India The present study was an attempt to investigate the preference of information sources by agriculture farmers. Study was conducted in Jaipur district of Rajasthan. 75 respondents were selected through random sampling method for the study and personal interview technique was used for data collection. Data related to information source used by the farmers revealed that mobile phone was the most preferred source by the farmers (70.66%). Farming helping apps (56%), television (53.33%), internet (52%) and local leader /neighbors (41.33%) always used by the farmers for accessing agriculture information. Study further revealed th...
