FORMAL TRADE BETWEEN INDIA AND BANGLADESH: AN EMPIRICAL ANALYSIS

The importance of improving trade flows between India and Bangladesh is not only beneficial to them, but for the whole SAARC region, given that Bhutan and Nepal utilise Bangladesh ports as gateways to trade outside the region. Bangladesh’s overall exports are dominated by labour-intensive manufacturing and its imports to India by primary commodities. The shares of manufactured goods in country’s overall export were about 92 and 91 percent in 2001 and 2011 respectively. However, the composition of bilateral trade between these two countries has been changing over time. Addition and removal in the list of products of trade basket is a usual process. Consistent products in the trade basket of Bangladesh are ready made garments and sea food, whereas those of India are raw cotton, cereals and products and machinery of iron and steel. Expansion of trade of these countries with outside world, but not with each other confirms the prevalence of certain barriers, physical or non-physical in nature, rendering many potential products remain untraded. India and Bangladesh being geographically proximate to each other possess huge scope to trade. Specifically as both the countries are rich in natural resources and are competent in the production of small-scale manufacturing and agrarian supplies, mostly from the eastern parts of India and Bangladesh, both possess huge potential for bilateral trade. Many items having high trade potential are still not able to get market exposure in the neighbouring country because of various non-tariff barriers prevailing in current trade scenario, which have hiked up the cost of doing business to unacceptable proportions and as most of the highly tradable products are still kept under the sensitive lists of Bangladesh. There are numerous bottlenecks in the current trade infrastructure which turns out to be physical barrier to trade. The present paper highlights the import export and Exchange Rate change and prospects of bilateral trade between the two countries

PRACTICING GREEN BUSINESS WITH SPECIAL REFERENCE TO INDIA: PERCEPTION AND COGNIZANCE OF RESEARCHERS

‘Green Business’ has risen in prominence.  Green supply chain management is a concept that is gaining popularity in the South East Asian region especially in India. For many organizations in India, it is a way to demonstrate their sincere commitment to sustainability.    For this purpose a conceptual model was developed from literature review and data used secondary sources.  The analysis identified that Awareness of Green Business in India   has been improving very slowly but now people of both countries are feeling that this area is having lot of scope to improve and they started to do work on this area.   This paper presents the   link between green business management practices and increased competitiveness and improved economic performance amongst a sample of organizations in India. India is fast growing country but slow in developing green business

Bianchi type II models in the presence of perfect fluid and anisotropic dark energy

Spatially homogeneous but totally anisotropic and non-flat Bianchi type II cosmological model has been studied in general relativity in the presence of two minimally interacting fluids; a perfect fluid as the matter fluid and a hypothetical anisotropic fluid as the dark energy fluid. The Einstein's field equations have been solved by applying two kinematical ans\"{a}tze: we have assumed the variation law for the mean Hubble parameter that yields a constant value of deceleration parameter, and one of the components of the shear tensor has been considered proportional to the mean Hubble parameter. We have particularly dwelled on the accelerating models with non-divergent expansion anisotropy as the Universe evolves. Yielding anisotropic pressure, the fluid we consider in the context of dark energy, can produce results that can be produced in the presence of isotropic fluid in accordance with the \Lambda CDM cosmology. However, the derived model gives additional opportunities by being able to allow kinematics that cannot be produced in the presence of fluids that yield only isotropic pressure. We have obtained well behaving cases where the anisotropy of the expansion and the anisotropy of the fluid converge to finite values (include zero) in the late Universe. We have also showed that although the metric we consider is totally anisotropic, the anisotropy of the dark energy is constrained to be axially symmetric, as long as the overall energy momentum tensor possesses zero shear stress.Comment: 15 pages; 5 figures; matches the version published in The European Physical Journal Plu

Formulation and evaluation of chitosan/chondriotin sulphate complex microcapsules for controlled delivery of water soluble drug

Oral route of drug administration is the most preferred route of drug administration but this route has its own limitations like pH of gastric media and controlling release rate of water soluble drug. To overcome these limitations, formulations containing controlled release matrix need to be developed. Controlled release of drug can be achieved by incorporating the drug into a release rate controlling carriers. Chitosan (CH)/Chondroitin Sulphate (CS) complex microcapsules were prepared to encapsulate the cardio vascular drug Propranolol hydrochloride (PHCl) by emulsion-chemical crosslinking method using sodium tripolyphosphate (STPP) as cross-linking agent. The FT-IR and DSC spectra’s revealed that there is no chemical interaction between drug and polymers used. Encapsulation efficiency and in-vitro drug release was found to be 64-84 % and 55-85 % respectively. Among all the formulations the F4.1 showed controlled drug release. This study revealed that the cross linked microcapsules of chitosan and chondroitin sulphate can be used to control drug release rate of water soluble drug.Colegio de Farmacéuticos de la Provincia de Buenos Aire

Inheritance study and stable sources of maydis leaf blight (Cochliobolus heterostrophus) resistance in tropical maize germplasm

Maydis leaf blight (MLB), a serious foliar fungal disease of maize, may cause up to 40% losses in yield. The present studies were undertaken to identify the stable sources of MLB resistance, its inheritance study, and testing of MLB resistance linked markers from diverse background in the Indian adapted tropical maize genotypes. A set of 112 inbred lines were screened under artificially created epiphytotics conditions at three hotspot locations. Analysis across multi-locations revealed significant effects of genotypes and environments, and non-significant effects due to genotypes × environment interaction on disease incidence. A total of 25 inbred lines with stable resistance were identified across multi-locations. Inheritance of resistance was studied in six F1s and two F2s of resistant and susceptible parents. The null hypothesis of segregation of resistance and susceptible for mono and digenic ratios in two F2 populations was rejected by Chi-square test. The non-significant differences among the reciprocal crosses depicted the complete control of nuclear genome for MLB resistance. Partial dominance in F1s and normal distribution pattern in F2s of resistant and susceptible parents suggested polygenic nature of MLB resistance. Correlation studies in F2 populations exhibited significant negative correlation between disease score and days to flowering. Five simple sequence repeats (SSRs) markers, found associated to MLB resistance in different studies were unable to differentiate amongst MLB resistance and susceptible parents in our study. This emphasizes the need of fine mapping for MLB resistance in Indian germplasm. The identified stable sources of resistance and information on inheritance study can be used further in strengthening of resistance breeding against MLB

Bianchi Type III Anisotropic Dark Energy Models with Constant Deceleration Parameter

The Bianchi type III dark energy models with constant deceleration parameter are investigated. The equation of state parameter $\omega$ is found to be time dependent and its existing range for this model is consistent with the recent observations of SN Ia data, SN Ia data (with CMBR anisotropy) and galaxy clustering statistics. The physical aspect of the dark energy models are discussed.Comment: 12 pages, 2 figures, Accepted version of IJT

Some anisotropic universes in the presence of imperfect fluid coupling with spatial curvature

We consider Bianchi VI spacetime, which also can be reduced to Bianchi types VI0-V-III-I. We initially consider the most general form of the energy-momentum tensor which yields anisotropic stress and heat flow. We then derive an energy-momentum tensor that couples with the spatial curvature in a way so as to cancel out the terms that arise due to the spatial curvature in the evolution equations of the Einstein field equations. We obtain exact solutions for the universes indefinetly expanding with constant mean deceleration parameter. The solutions are beriefly discussed for each Bianchi type. The dynamics of the models and fluid are examined briefly, and the models that can approach to isotropy are determined. We conclude that even if the observed universe is almost isotropic, this does not necessarily imply the isotropy of the fluid (e.g., dark energy) affecting the evolution of the universe within the context of general relativity.Comment: 17 pages, no figures; to appear in International Journal of Theoretical Physics; in this version (which is more concise) an equation added, some references updated and adde

Non-Gaussian isocurvature perturbations in dark radiation

We study non-Gaussian properties of the isocurvature perturbations in the dark radiation, which consists of the active neutrinos and extra light species, if exist. We first derive expressions for the bispectra of primordial perturbations which are mixtures of curvature and dark radiation isocurvature perturbations. We also discuss CMB bispectra produced in our model and forecast CMB constraints on the nonlinearity parameters based on the Fisher matrix analysis. Some concrete particle physics motivated models are presented in which large isocurvature perturbations in extra light species and/or the neutrino density isocurvature perturbations as well as their non-Gaussianities may be generated. Thus detections of non-Gaussianity in the dark radiation isocurvature perturbation will give us an opportunity to identify the origin of extra light species and lepton asymmetry.Comment: 32 pages, 7 figure
