Leuceana lucocephala is a small tree originated and scoped as a weed in tropical and warm temperate region of other countries in India .it mostly cultivated for its fodder fuel, timer and other important uses like huge plant, green manure, food for animal and like a bio energy crop. Leucaena Leucocephala, commonly called subabul in the locality of Vidisha district, has considered for crop intensification .Leucaena Leucocephala has also considered among the fast-growing, multipurpose nitrogen-fixing trees, hence, it has regarded by the nickname “Miracle tree”. In recent years, subabul has become popular among farmers in the southern states also due to its ability to produce pulpwood within a three to five years. On this basis, leucaena  leucocephala was selected as potential pulping raw material and alternative source fiber for making the paper. The Leuceana Leucocephala plant has high nutritive content like carbohydrats, protein and fat as alfalfa.it is used as a raw material for making paper, agriculture implements and the seed oil could be used as biofuel by blending with the conventional diesel.

The aryldiazonium salt is used as intermediate in different reactions because, Ar-N_2⁺Cl^- are highly reactive compounds. These reactions, either, losses nitrogen containing function or without loss of nitrogen function. In the present piece of work we have reacted the five aryldiazonium salt with phenolic compound (Resorcinol). The final product, 1 to 5 formed has potential to use as azo dyes and as intermediate in other synthetic procedures or transformations

The rare aromatic ketone, 5-Chloro-2-hydroxy-4-methyl-acetophenone is condensed with aniline and its six dialkyl derivatives viz. 2,3-Dimethyl-aniline, 2,4-Dimethyl-aniline, 3,4-Dimethyl-aniline, 2,5-Dimethyl-aniline, 2,6-Dimethyl-aniline,and 3,5-Dimethyl-aniline(each separately) efficiently to produced a series of novel ketimines, CJ-0 to CJ-6. These were analyzed by employing the techniques such as thin layer chromatography(TLC) and UV-Vis spectra. All these novel ketimines were characterized by their colour, physical constant, TLC, elemental analysis and spectral(UV-Vis and FTIR) methods. After confirming their desired molecular studies, these novel ketimines were studied for their biological potential.

Fluorine is the 13^th most abundant element on earth. It cannot exist outside a controlled environment without combing with other substances to become fluorides. Three main anthropogenic sources were identified as fertilizers, combusted coal and industrial waste with phosphate fertilizer being the most significance source of fluoride. There are ionisable and non-ionisable, organic and inorganic fluorides.  Rajasthan suffers both the problems of quantity and quality of water. In most part of the state groundwater is either saline or having high nitrates and fluoride content. The entire state is principally dependent on groundwater for its needs. The hydro geological environment controls the occurrence, distribution and movement of groundwater. Poor rainfall and excessive dependence on ground water, both for agricultural irrigation and drinking water coupled with over exploitation of ground water has made the task of providing safe and potable water supply, more difficult. The physicochemical characteristics of the ground water samples were determined by standard methods .The pH and Electrical conductivity were measured by using portable meters. The concentrations of Magnesium, Calcium hardness, total hardness, nitrate, were estimated by volumetric methods and the results are compare with Water standards. The present investigation was therefore undertaken to workout relationship between different indices of water quality by determining correlation coefficients (r Value) between each pair of parameters for all possible correlations. The linear relationship of the type Y= mx + C (m is slope and, C is intercept) are obtained for parameters. The corresponding linear relationships (regression equations) were observed. The analysis of ground water shows higher values of fluoride and nitrate in the drinking water samples of almost all locations, some places have higher values of alkalinity and chloride while remaining parameters are within the permissible limits. In these areas, the treatment technologies must be implemented to ensure good health of the community.
