In this study, water quality and eutrophication aspects of Mansar, Surinsar, Tsokar, Tsomoriri and Renuka lakes have been discussed. The water quality parameters were compared with BIS standards for drinking purposes. The values of physico-chemical water quality parameters for Mansar and Surinsar lakes (Jammu Division) were found within the desirable limits except low DO in hypolimnion. Whereas, the values of physico-chemical parameters for Tsomoriri and Tsokar lakes (Ladakh region) were found beyond limits having much higher concentration of pH, total dissolved solids, total hardness, chloride, calcium, magnesium. The water quality of Renuka lake shown higher concentration of magnesium, iron, manganese, lead, total coliform, faecal coliform and low DO in hypolimnion. The eutrophication status assessed on the basis of phosphate concentration show eutrophic condition of Mansar, Surinsar, Tsomoriri and hyper-eutrophic condition of Tsokar and Renuka lake. The results indicate that efforts are required to lower the existing eutrophication levels by adopting conservation measures for the lakes.

Energy and pollution are the present burning questions. So, there is an impending demand of an alternative green power. Solar, as believed, is the only major alternative in comparison to other sources of available renewable energies. For absorbing the sun solid silicon-crystalline photo-voltaic (SPV) method is the best. SPV panels are laid on structures at tilt angle. SPV is a land consuming system. Scarcity of land is the greatest crisis of the earth. Solar Power Tree is invented for installing PV-modules on a tall pole-like structure with branch- like panels and takes only 1% of land than conventional SPV layout.

The discovery of carbon nanotubes has created new era in the field of nanotechnology. Spectacular properties of these nanostructured materials, stimulating scientists to peep into this tiny tube with ever increasing curiosity. The immediate challenge is to produce desired structural and characteristic featured carbon nanotubes in large quantities. Chemical vapor deposition is the most popular method of producing carbon nanotubes and it is of low-cost and highly useful technique for mass production of carbon nanotubes. These efforts requires not only chosen technique but also based on the precursor and the catalytic support. Glycine max oil a botanical hydrocarbon, has been found to be effective precursor for the synthesis of multi-walled carbon nanotubes (MWNTs) by Spray Pyrolysis over well dispersed Fe /Mo catalyst supported on silica at 650 °C under Ar atmosphere. As-grown MWNTs were characterized by SEM, HRTEM, Raman spectroscopy and Nitrogen adsorption studies. Raman spectroscopy revels that MWNTs are well graphitized. Dynamic and equilibrium studies of adsorption of Basic brown-4 on MWNTs were also reported.

In recent years, an Axisymmetric Bessel-modulated Gaussian beam with quadratic radial dependence (QBG beam) has attracted very much. In this paper, Focal shift in radially polarized QBG beam with radial variance phase wavefront is investigated theoretically byvector diffraction theory. The wavefront phase distribution is cosine function of radial coordinate. Simulation results show that the intensity distribution in focal region of the radially polarized QBG beam can be adjusted considerably by small beam parameter

Indigenous Traditional Knowledge (ITK) on herbal medicines is gaining importance continuously, due to their efficiency, rare chances of side effects in the treatment, good faith of society on herbal medicines and their products. The present study was carried out on the tribal communities i.e., the Bhotias and Gangwals. A non-participant observation method was used to extract the knowledge from local medicine men. Ethno-medicinal uses of local plants by the natives the Bhotias and Gangwal tribes were documented.In this paper a total of 78 plants belonging to 39 families and 61 genera were recorded, which were used for the treatment of 68 diseases. Out of 78 plants, roots and rhizomes of 26 are used for medicine preparation followed by leaves (20), fruits (03), whole plant/ aerial parts (10/04), seeds (07), bark (07), flowers (07), stem (01), aerial bulbs (01), latex (02), resin (01). About 07 species were commonly used for treating wounds/ sores followed by 05 species for treating fever and 05 species for headache, 04 species each for pregnancy problems, sprains, urine problem and cold and cough. Twenty one species were found using for curing more than one ailments while 57 species were reported for single therapeutic application. Twelve species are also used as dyes, spices, condiments, flavouring agent and food items and play a significant role is rural economy of the region. P.S. Mehta E-mail: mehta.puran@yahoo.com Now, due to change of socio-economy and culture, the traditional knowledge of these communities is also diminishing. It needs to be preserved before the onslaught of modernization. There is also an urgent needof conservation and resource augmentation of these medicinal plants in their natural habitat as well as their plantation in suitable agro-climatic conditions. Thus, it was concluded that the tribes Bhotias and Gangwals possess a good knowledge of herbal based medicinal practice.

Corrosion is an unintentional gradual degradation of metal that occurs because of chemical or electrochemical attach. The corrosive nature of the gaseous environment at high temperature may cause rapid material degradation and result in premature failure of components. Boiler tubes in power plant are subjected to a wide variety of failure due to high temperature corrosion fatigue. For the reduction of corrosion either a material of required mechanical properties is used, which is impossible for a single material to have all these properties or provide the coating to existing material with surface coating methods, which improves the existing properties in economical way and reduce the cost of replacement. In this paper an attempt has been made by conducting the experimental work on SAE213 T-22 boiler steel tubes with different coating powders having composition of WC-10% CO-4% Cr and WC-12% Cr by adopting the High Velocity Oxy Fuel (HVOF) thermal spray technique to protect the boiler tubes from hot corrosion in gaseous environment and do the various calculations to made the comparison between uncoated and coated tube materials, by creating the artificial environment in the lab.
