The synthesis of chalcone system -C=C-C=O is relatively easy to prepare, usually highly reactive and are starting point of preparation of various bioactive compounds. This, -unsaturated ketones (chalcones) can be synthesized by Claisen-Schmidt condensation of different aromatic aldehydes with ketone and their cyclization with hydrazine hydrate in basic condition. Numerous pyrazoline derivatives have been found to possess considerable biological activities, which stimulated the research activity in this field. Amongst all the nitrogen containing five member heterocycles, it have proved to be...

There are crisis of drinking water all over the world and ground water is the major source of all, as more than 90% of water is of no use for such purpose. This source is under tremendous pressure caused mainly by human activities. Groundwater also has an important role in the environment: it replenishes streams, rivers, and wetlands and helps to support wildlife habitat; it is used as primary source of drinking water and also in agricultural and industrial activities. Keeping these things in mind and starting the study are from home ground the groundwater quality of various regions of...

The present investigation was undertaken for studying the economic utility of Prosopis juliflora pods growing in different habitats like sandy and marshy of Kachchh region of Gujarat in India. Along with prosopis pods from different habitats collected, a commercial cattle feed was also analyzed and compared with the Prosopis juliflora pods. Various parameters like Calcium, Magnessium, Chloride, Sodium, Potassium etc. were analyzed from the pods and soil supporting the plant.
