Standardization of herbal formulations is essential in order to assess the quality of drugs, based on the concentration of their active principles, physical and chemical standards. This article reports on standardization of a Polyherbal ayurvedic formulation used as anti-hyperlipidemic. Specific morphological parts of the plants are used in the Polyherbal formulation. Polyherbal formulation has been standardized on the basis of organoleptic properties, physical characteristics, and physico-chemical properties.

The study of generalized field associated with Abelian dyons has been undertaken and it has been demonstrated that topologically, a non-Abelian gauge theory is equivalent to a set of Abelian gauge theories supplemented by dyons which undergo condensation leading to confinement and consequently to superconducting model of QCD vacuum, where the Higgs field plays the role of a regulator only. Constructing the effective action for dyonic field in Abelian projection of QCD, it has been demonstrated that any charge (electrical or magnetic) of dyon screens its own direct potential to which it minimally couples and anti-screens the dual potential leading to dual superconductivity in accordance with generalized Meissner effect. In this Abelian projection of QCD an Abelian Higgs model (AHM) has been successfully constructed and it has been shown to incorporate dual superconductivity and confinement as the consequence of dyonic condensation. It has been demonstrated that in AHM t’ Hooft loop creates the string (AHM-string) around which the monopole current under London limit leads to vanishing coherence length in the chromo-magnetic superconductor. It has also been shown that in London limit the squared density of monopole current around AHM-string has a maximum at the distance of the order of penetration length. © 2016 Springer Science+Business Media New York

Ethnoveterinary medicine is the holistic interdisciplinary study of the local knowledge and the socio-cultural structures and environment associated with animal healthcare and husbandry. The investigation is aimed at clearing some facts and Indian concepts of ethnoveterinary science. The paper deals with 23 household plants and plant products which are used in the treatment of animal diseases by local people and tribes of Uttarakhand.

Variability in premonsoon precipitation, which has direct impact on rabi crop productivity in the Himalayan region, is not well understood in a long-term perspective, largely due to the paucity of weather data. We developed an annually resolved February-May (FM) precipitation record extending back to AD 1730 using tree-ring width data of Himalayan cedar for the first time from the Kumaon region, eastern sector of the western Himalaya, India. The FM precipitation reconstruction, capturing 58% of the variance in instrumental data over the calibration period (1901-1968), is the strongest so far from the Indian region. The reconstruction revealed inter-annual to decadal-scale variations in precipitation anomalies. Twentieth-century decadal-scale droughts occurred in the 1920s, and 1960s to early 1970s, and pluvials in the 1910s and 1980s. However, the droughts in 1920-1924 were the most severe of any other comparable period in last three centuries. Pre-instrumental droughts of the 1740s, 1780s, and 1840s were widespread in a large part of the western Himalaya. The drying tendency noted in the last two decades, which is widespread in the western Himalaya and western Nepal, in view of increased hydrological demand is alarming, and could cause severe water stress in the region unless adaptive measures are taken. © 2013 Elsevier Ltd and INQUA.

This paper examines the role of local and regional institutions in environmental governance in Hindu Kush Himalaya (HKH). These institutions have been playing a significant role in regional environmental governance, particularly through generating and disseminating critical knowledge, mobilizing resources and addressing marginality, and regional environmental fragility. However, local and regional institutions have not yet comprehensively addressed the issues of poverty, livelihood, food security, gender inequality, education and social marginalization that affect the entire process of environmental governance. Community access to and involvement in critical socio-economic sectors such as infrastructure and health and education systems, including their governance processes, did not improve due to a lack of inter-linkages within and between local and regional institutions. This underlines the need for capacity building and the development of partnerships and horizontal and vertical linkages among local, regional and national institutions. These practical advances would facilitate improved access to new knowledge, technology and critical information and encourage the movement of financial resources to local levels. © 2014 Elsevier Ltd.

The essential oils of four wild growing Origanum vulgare L. (family Lamiaceae) collected from different locations in Kumaon region (Uttarakhand, India) were analysed by capillary GC and GC/MS. The comparative results of O. vulgare L. collected from four different regions showed differences in the chemical constituents of the essential oils. The oil of O. vulgare L. collected from Dhoulchina and Champawat (chemotype I) shows p-cymene (6.7-9.8%), γ-terpinene (12.4-14.0%), thymol (29.7-35.1%) and carvacrol (12.4-20.9%) as major constituents while the oil from Kilbury and Rushi village (chemotype II) shows linalool (6.7-9.7%), bornyl acetate (12.6-16.8%), β-caryophyllene (10.5-13.8%) and germacrene D (6.3-11.3%) as the major constituents. These features highlight the chemosystematics of this genus. © 2012 Copyright Taylor and Francis Group, LLC.

The study of superconductivity has been undertaken through the breaking of supersymmetric gauge theories which automatically incorporate the condensation of monopoles and dyons leading to confining and superconducting phases. Constructing the effective Lagrangian near a singularity in moduli space for N=2 supersymmetric theory with SU(2) gauge group, it has been shown that when a mass term is added to this Lagrangian, the N=2 Supersymmetry is reduced to N=1 supersymmetry yielding the dyonic condensation which leads to confinement and superconductivity as the consequence of generalized Meissner effect. In the Coulomb phase of N=2 SU(3) Yang-Mills theory the gauge symmetry has been broken down to SU(2)×U(l) and it has been shown that on perturbing it by suitable tree-level superpotential this supersymmetry theory breaks to N=1 SU(2) Yang-Mills theory described by Higgs field in confining phase incorporating superconductivity. © 2011 Springer Science+Business Media, LLC.

An old variational principle (Maupertuis principle), forgotten as inconvenient quirk of history, has been reformulated into the modified variational principle (MVP) along with its reciprocal principle (RMP) and both these principles have been derived classically as well as quantum mechanically. Wide scope of applicability of these new principles in classical mechanics has been demonstrated by solving the problems of Linear Oscillator, Anharmonic Oscillator and Anisotropic 2D-Quartic Oscillator (chaotic system).©2011 Academic Journals.

Entanglement has been explored as one of the key resources required for quantum computation, the functional dependence of the entanglement measures on spin correlation functions has been established, correspondence between evolution of maximally entangled states (MES) of two-qubit system and representation of SU(2) group has been worked out and the evolution of MES under a rotating magnetic field has been investigated. Necessary and sufficient conditions for the general two-qubit state to be maximally entangled state (MES) have been obtained and a new set of MES constituting a very powerful and reliable eigen basis (different from magic bases) of two-qubit systems has been constructed. In terms of the MES constituting this basis, Bell's States have been generated and all the qubits of two-qubit system have been obtained. It has shown that a MES corresponds to a point in the SO(3) sphere and an evolution of MES corresponds to a trajectory connecting two points on this sphere. Analysing the evolution of MES under a rotating magnetic field, it has been demonstrated that a rotating magnetic field is equivalent to a three dimensional rotation in real space leading to the evolution of a MES. © 2013 Springer Science+Business Media New York.
