Kangra, India

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.

The recently invented ThFeAsN superconductor, belonging to the family of Fe-based superconductors, has been studied using ab initio density functional theory. Our calculations demonstrate that the electronic structure of this superconductor is similar to that of other Fe-based superconductors with computed magnetic ground state showing strong dependence on atomic positions. Using relaxed atomic positions, the single- and double-stripe magnetic states are found to be energetically close to each other, which may lead to stripe-like antiferromagnetic spin fluctuations. We speculate that such energetic degeneracy among two antiferromagnetic structures may be an ideal condition for strong stripe-like antiferromagnetic spin fluctuations, which may be playing a key role in obtaining high transition temperature of 30 K. Fixed spin moment calculations demonstrate the possibility of local minima for magnetic states in ThFeAsN. The absence of long-range ordering in ThFeAsN may be due to presence of such local minima. © 2017 The Minerals, Metals & Materials Society

Laser-based approaches for graphene synthesis, reduction, modification, cutting and micro-patterning have been developed and applied to the fabrication of various electronic devices. These laser-based techniques exhibit several advantages over alternative methods: low temperature, shorter reaction times, environmentally friendly, energy saving, catalyst free growth on insulating substrates, high productivity, better reproducibility, scalability, excellent control over experimental parameters. Given the importance of the subject, in the last few years a remarkable increase in the number of scientific articles has occurred in this area. Direct fabrication of graphene patterns for micro-supercapacitors, flexible electrodes, field-effect-transistors, and sensors are some of the examples. Direct laser writing enables local graphene synthesis and fabrication of graphene patterns on graphene oxide films. It can be used to achieve band gap modulation, removal of surface functionalities, conductivity enhancement, exfoliation and porous structure formation. The aim of this review is to collect some of the most relevant research efforts published on this important topic, with emphasis in the articles published in the last few years. After an introduction highlighting the main factors affecting the outcome of laser-materials interactions, devices built using direct laser writing (DLW) on graphene oxide/graphene films and the experimental conditions used for their fabrication are summarized. Some of the expected directions for promising future research in this area are briefly discussed. © 2017 Elsevier B.V.

Outer membrane proteins (OMPs) in eubacteria have several important roles, which range from membrane transport to the host-pathogen interactions. These are directly involved in pathogen attachment, entry and activation of several pathogen-induced signaling cascades in the cell. The cardinal structural features of OMPs include the presence of a β-barrel, a signal peptide and the absence of the transmembrane helix. This is the first report on proteome-wide identification of OMPs of ruminant pathogen, Mycobacterium avium subsp. paratuberculosis (MAP). The complete proteome of MAP was analyzed using a pipeline of algorithms, which screens the amino acid sequences and structural features shared by OMPs in other bacteria. Secondary structure of these proteins is also analyzed and scores are calculated for amphiphilic β-strands. From the set of 588 exported proteins, 264 proteins are predicted to be inner membrane proteins while 83 proteins are identified as potential OMPs in MAP. Finally, this study identified 57 proteins as top candidates, on the basis of computed isoelectric points, as the core set of OMPs. Significantly, the resulting data for OMPs are not only useful in designing novel vaccines but may also open avenues for the development of early serodiagnostic tools for MAP. © 2014 the Partner Organisations.

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.

Environmental Science and Pollution Research | Year: 2014

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.

After the observation of non-zero θ13 the goal has shifted to observe CP violation in the leptonic sector. Neutrino oscillation experiments can, directly, probe the Dirac CP phases. Alternatively, one can measure CP violation in the leptonic sector using Leptonic Unitarity Quadrangle (LUQ). The existence of Standard Model (SM) gauge singlets – sterile neutrinos – will provide additional sources of CP violation. We investigate the connection between neutrino survival probability and rephasing invariants of the 4×4 neutrino mixing matrix. In general, LUQ contain eight geometrical parameters out of which five are independent. We obtain CP asymmetry (Pνf→νf′−Pν¯f→ν¯f′) in terms of these independent parameters of the LUQ and search for the possibilities of extracting information on these independent geometrical parameters in short baseline (SBL) and long baseline (LBL) experiments, thus, looking for constructing LUQ and possible measurement of CP violation. We find that it is not possible to construct LUQ using data from LBL experiments because CP asymmetry is sensitive to only three of the five independent parameters of LUQ. However, for SBL experiments, CP asymmetry is found to be sensitive to all five independent parameters making it possible to construct LUQ and measure CP violation. © 2016 The Authors

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.

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.

We present an overview of recent progress in the theoretical and phenomenological studies of neutrino masses, lepton avor mixing, and CP violation. Firstly, We discuss the status of neutrino mass with in the Standard Model (SM) of particle physics. Then the possible ways in which neutrino mass terms can be included in the SM are discussed. The inclusion of new physics beyond the SM inevitably brings new parameters which are not constrained by the present experimental data on neutrino masses and mixing angles and, thus, are free parameters of the theory. We, also, discuss various theoretically motivated phenomenological approaches which can be used to reduce the number of free parameters and, thus, provide an excellent tool to understand the underlying physics of neutrino masses and mixings. Current experimental constraints on the neutrino mass spectrum and the lepton avor mixing parameters, including the recent observation of nonzero θ 13, have been summarized. Finally, We discuss the renewed interest in the possible existence of one or more sterile neutrinos and their phenomenology. © 2015 Surender Verma.
