The Central University of Himachal Pradesh is operating from temporary academic block which is established at Shahpur,Himachal Pradesh. The university will have its two permanent campuses viz Beas campus at Dehra and Dhauladhar campus at Dharamshala. This university was previously allotted to Dehra town but due to political propaganda same was shifted to Shahpur for temporary classes although enough space was provided at Dehra and later divided into two location for political benefits. The university was founded in 2009 as a result of the government's policy to establish Central Universities in each of the states that do not already have a central university. Wikipedia.

We show that the global nonlinear stability threshold for convection in a couple-stress fluid is exactly the same as the linear instability boundary. This optimal result is important because it shows that linearized instability theory has captured completely the physics of the onset of convection. It is also found that the couple-stress fluid is thermally more stable than the ordinary viscous fluid and then the effect of couple stress parameter on the onset of convection is also analyzed. © 2011 Elsevier Ltd.

Purpose: E-waste is the most rapidly growing problem throughout the world, which has serious future concerns over its management and recycling. This article proposes a simple approach for future e-waste projection which can be obtained by using life-span data of various electronic items along with incorporation of population statistics. Methods: For this purpose, 7-year sales data of electronic items were collected, which is then used to generate various mathematical equations. These mathematical relations are then modified by incorporating life-span and population data. Results and discussion: By comparing sales data with their life-span (average) and population statistics, future e-waste can be quantified both in terms of specified area under investigation and proposed estimation area. The following equation is thus proposed: E - waste (In terms of quantity) = [m {Waste projection year - Life span} - Initial data collection year + C] × Population of estimation area/ Population of study area Where m and C can be obtained from plotting year-wise sales data over Excel sheet. Conclusions: Local as well as global projection of future e-waste can be possible with the help of final equation. © 2013 Springer-Verlag Berlin Heidelberg. Source

Pollution resulting from hazardous glass (HG) is widespread across the globe, both in terms of quantity and associated health risks. In waste cathode ray tube (CRT) and fluorescent lamp glass, mercury and lead are present as the major pollutants. The current review discusses the issues related to quantity and associated risk from the pollutant present in HG and proposes the chemical, biological, thermal, hybrid, and nanotechniques for its management. The hybrid is one of the upcoming research models involving the compatible combination of two or more techniques for better and efficient remediation. Thermal mercury desorption starts at 100 °C but for efficient removal, the temperature should be >460 °C. Involvement of solar energy for this purpose makes the research more viable and ecofriendly. Nanoparticles such as Fe, Se, Cu, Ni, Zn, Ag, and WS2 alone or with its formulation can immobilize heavy metals present in HG by involving a redox mechanism. Straight-line equation from year-wise sale can provide future sale data in comparison with lifespan which gives future pollutant approximation. Waste compact fluorescent lamps units projected for the year 2015 is 9,300,000,000 units and can emit nearly 9,300 kg of mercury. On the other hand, CRT monitors have been continuously replaced by more improved versions like liquid crystal display and plasma display panel resulting in the production of more waste. Worldwide CRT production was 83,300,000 units in 2002 and can approximately release 83,000 metric tons of lead. © 2013 Springer-Verlag Berlin Heidelberg. Source

E-waste now has been a rapidly growing problem in terms of quantity and toxicity of its components. Recycling of e-waste becomes rather complicated because of the technological advancement in the materials and composition of the e-equipment. From the management perspective e-waste components can be divided in two categories: 1) organic part contains thermo and thermosetting plastic; 2) inorganic parts consists of metallic and non-metallic components. The current review addresses the various environmental issues related to existing management and proposes microbial participation as a viable and eco-friendly technique. Microbial participation improves the process in a greener way and this technology can be applied for the treatment of both organic as well as inorganic part of the e-waste. It affects organic part principally by its dehalogenation and inorganic part by metal xtraction pattern. © 2014 Inderscience Enterprises Ltd. Source

Recycling method of polycarbonate (PC) plastic using glycerol is proposed as a novel green method. Glycerol was found as an efficient reagent for chemical recycling of PC and gives upto 98% monomer recovery, which is compatible with any of existing chemical recycling methods. Recycling involves digestion followed by glycerolysis reaction of PC. The various products thus obtained are Bisphenol A (BPA); mono glycerol ether of BPA and di glycerol ether of BPA. Addition of urea improves the yield toward more alkoxylated products, controls the dehydration of glycerol to acrolein at reaction temperature and improves the application of glycerol as a reagent. Temperature programmed FTIR spectra study provides a mechanistic picture of the proposed chemical recycling. Glycerol carbonate and glycerol urethane was found as the important reaction intermediates. The process works well with industrial grade glycerol to improve the economy in this process. Furthermore, a working model of the recycling of post-user optical disc is also proposes. © 2016 The Institution of Chemical Engineers. Published by Elsevier B.V. All rights reserved. Source
