A lake is a large body of water surrounded by land and inhabited by various aquatic life forms. Lakes are subjected to various natural processes taking place in the environment, such as the hydrological cycle. Due to tremendous population growth of the city and rapid urban development, lakes are facing various environmental problems resulting in deterioration of its water quality The present investigation was carried out from may 2014 to may 2015 to study the hydrobiology of the shahpura lake of Bhopal (M.P), with special reference to its management. The physico-chemical parameter we have used are pH, Water temperature, transparency, dissolved oxygen, free carbon dioxide, B.O.D., Chloride, Nitrate, Alkanity, total hardness etc. These parameters suggest that the lake is medium productive. The fish yield of the lake if managed properly on scientific lines can be enhanced.

In the Jaintia Hills of Meghalaya large scale coal mining operation is going on since 1970. In these areas coal is extracted mainly by rat hole mining method. In the rat hole method large scale labours are employed in areas to carry out the mining operation. In doing so huge number of child labours are being engaged specially from Bangladesh and Nepal. These child specially in the age group of 10 - 14 years are brought from the neighboring countries. In these mining areas human rights are violated for these children’s - these children are being forced to work which is a violation of Article 23 of Indian constitution. They are being imported specially from adjoining countries as a traffic in human beings. Among child below the age of 14 years are also engaged for digging the coal. They work in a dangerous condition which is a type of exploitation and their normal human rights are violated.

Active and passive noise controlling methods are widely used for noise reduction applications as it is essential to control unwanted noise and vibration which adversely affects human life, wild life, aquatic life and the ecosystem as such. The technological, automobile and biomedical world also prefer noise and vibration free atmosphere for the efficient performance. However, passive noise reduction at lower frequency range is highly challenging due to the unavailability of suitable materials. The emergence of engineered composite materials pave way to this bottle neck problem. Herein, natural fiber composites are synthesized using Vacuum Assisted Resin Transfer Molding and characterized for noise reduction in the low frequency region with the help of transfer matrix method using an impedance tube. The results show that the natural micro fibrous basalt fiber composite is a highly efficient sound absorber in the lower frequency region compared to the glass fiber based one. The fiber radius is critical in tuning the frequency range. The contact angle measurements reveals that the basalt fiber composite is more hydrophobic in nature.

In the present work, different methods were used to calculate the atomic cross-sections, electronic cross-sections, effective Z, effective electron density and mean free path for the Bi4Ge3O12 gamma ray detector popularly known as BGO detector. The methods are Direct method using attenuation coefficients evaluated using WinXCom software, the others are DirectZeff software, AutoZeff software, XMuDat software and still another method used is Power law method. The results of first two methods i. e. Direct method and Direct Zeff software are in good agreement with each other. These results are also reproduced nicely by power law method. The Zeff predicted by AutoZeff are too large compared with our predictions and XMuDat predicts too small value for Zeff

The alpha–hydroxy acids (AHA) are naturally occurring organic acid. The oxidation of mandelic acid by pyridiniumdichromate has been studied spectrophotometrically in presence of p-toluenesulphonic acid (PTSA) in dimethylsulphoxide (DMSO) as a solvent. The rate of reaction decrease & with an increase in polarity of solvent indicating an ion-dipole interaction in the slow step. The reaction exhibit no primary kinetic isotope effect. The activation parameters have been evaluated.

Water temperature affects plants in many ways. A change of temperature alters metabolic activity and even affects aquatic ecosystems. From houseplants to aquatic plants, water temperature plays a part in growth and development Water temperature has a direct effect on the growth of aquatic plants. An unnatural introduction of warm water into a water body is called thermal pollution. Thermal pollution alters the population dynamics of aquatic plants. Also, some aquatic plants float to the surface in warm water. In this study we strongly explained that water temperature can fluctuate in every season which directly affect aquatic ecosystem .water temperature is taken from the month jan 16 to june 16 which ranges from28oC-42oC that shows large variation in plankton growth.
