Dynamics of socio-economic development of districts of eastern Uttar Pradesh

Development process of any system is dynamic in nature and depends on large number of parameters. This study attempted to capture latest dynamics of development of districts of Eastern Uttar Pradesh in respect of three dimensions- Agriculture, Social and Infrastructure. Techniques adopted by Narain et al. (1991) have been used in addition to Principal component and factor analysis. Ranking seems to very close to ground reality and provides useful information for further planning and corrective measures for future development of Eastern UttarPradesh’s Districts. The Composite Indices (C.I.) of development in respect of 18 developmental indicators for the total 28 districts of eastern Uttar Pradesh have been estimated for the year 2010-2011. The district Barabanki was showed a higher level of development (C.I. =0.10) in Agricultural development compared to Social development (C.I.=1.12) and Infrastructural development (C.I. =0.89) followed by the district Ambedkar nagar (Agricultural, C.I. =0.52), (Social, C.I. =1.12) and (Infrastructure, C.I. =0.89). District Allahabad secured first position in the Social development (C.I. =0.81) and second in Infrastructural development (C.I. =0.34) as compared to Agriculture (C.I. =0.93). District Varanasi was the most developed district in Infrastructure (C.I. =0.10) as compared to Agriculture (C.I.=0.96) and Social (C.I. =0.96). As per findings of the study, the two districts Mau and Jaunpur were down in their ranking and the districts Chandauli and Maharajganj improved their ranking

Hepatitis E virus: the current scenario

SummaryHepatitis E infection, caused by the hepatitis E virus (HEV), is a common cause of acute hepatitis in developing countries with poor sanitation and hygiene. The virus is classified into four genotypes (1–4) with one serotype. Genotypes 1 and 2 exclusively infect humans, whereas genotypes 3 and 4 also infect other animals, particularly pigs. In endemic areas, large outbreaks of acute hepatitis caused by viruses of genotype 1 or 2 frequently occur due to fecal–oral transmission, usually through contamination of drinking water. With a high attack rate in young adults (aged 15–45 years), the disease is particularly severe among pregnant women (20–30% mortality). HEV appears to be a zoonotic disease, with transmission from pigs, wild boars, and deer, or foodborne. Chronic infections are rare, except in immunosuppressed persons, such as organ transplant recipients. A subunit vaccine has been shown to be effective in preventing the clinical disease, but is not yet commercially available. Our understanding of HEV has undergone major changes in recent years and in this article we review the currently available information with regard to the molecular biology, pathobiology, and epidemiology of HEV infection. We also review the current therapeutic interventions and strategies being used to control HEV infection, with emphasis on possible approaches that could be used to develop an effective vaccine against HEV

Evaluation of Anthelmentic and Antimicrobial Activity of the Extract of the Root of the Plant Jasminum multiflorum(Andr.)

As per qualitative evaluation in different solvents of the root of the plant satisfies the presence of cardiac glycosides along with trace quantities of steroid and saponins. Among them the petroleum ether extract of the root of the plant Jasminum multiflorum was evaluated for anthelmintic activity and the ethanolic extract was evaluated for antimicrobial activity.1,2 Traditionally this species are used in indolent ulcer, pitta and inflammation. Only few CNS activity are reported on ethanolic extract of aerial part of the plant, though the root of the plant is more potent as per folkore claim. The petroleum ether extract was investigated for anthelmentic activity using earthworm (Pheretima posthuma) at different concentration (5mg/ml – 50 mg/ml). As standard albendazole suspension (10mg/ml) and 3% solution of normal saline was used as control. The death and paralysis time were recorded and compared. Extract exhibit significant anthelmentic activity at (100mg/ml) concentration and found effective.1,3,4The ethanolic fraction of the root of the plant was collected and evaporated to dryness under vacuum to avoid the presence of even less quantity of ethanol in the extract. Two Gram (+ve) bacteria namely Bacillius subtilis, Staphylococcus aureus and two Gram (-ve) ve bacteria namely Escherichia coli and Klebsiella pneumonia were selected for the estimation of antimicrobial activity depending on zone of inhibition. It was seen that 100mg/ml concentration of the extract showed maximum activity against Klebsiella pneumonia with a zone of inhibition 0.5mm and for others it ranged from 0.3 to 0.4 mm. 1,4,5 Keywords: Jasminum multiforum; anthelmintic; antimicrobial; zone of inhibitio

Effect of synthetic fibres on concrete with GGBFS replaced cement

Concrete is used widely in many construction activities. As cement is getting costlier and demand is growing more day by day, investigators have been trying to replace cement with other materials to save money either by maintaining the properties using waste materials or by enhancing the properties using selected materials. This paper is an attempt to study the various engineering properties of a concrete made with cement replaced by ground granulated blast furnace slag. To maintain the engineering properties, a synthetic fiber namely Recron 3s fibers manufactured by Reliance Industry Limited, India (RIL) and commonly available in the local retail market of India, has been used in various proportions. The experimental investigations include basic tests for cement, and conventional tests for concrete such as compressive strength, split tensile strength and flexural strength have been taken up. The capillary tests and porosity tests have been also conducted to study the effects of concrete in respect of resistance to seeping or dampening. It has been observed that the Recron fibers to the extent of 0.2% fiber content maintain the satisfactory properties of concrete. However, the resistance to capillary action and porosity problems in concrete is improved considerably

On the order of a non-abelian representation group of a slim dense near hexagon

We show that, if the representation group $R$ of a slim dense near hexagon $S$ is non-abelian, then $R$ is of exponent 4 and $|R|=2^{\beta}$, $1+NPdim(S)\leq \beta\leq 1+dimV(S)$, where $NPdim(S)$ is the near polygon embedding dimension of $S$ and $dimV(S)$ is the dimension of the universal representation module $V(S)$ of $S$. Further, if $\beta =1+NPdim(S)$, then $R$ is an extraspecial 2-group (Theorem 1.6)

Formulation and Characterization of Alginate Microbeads of Clonidine Hydrochloride by Ionotropic Gelation Technique

The objective of this study was to prepare and evaluate sodium alginate microbeads with calcium chloride as cross-linking agent for Clonidine hydrochloride by ionotropic gelation method. Clonidine hydrochloride a centrally acting sympatholytic and imidazoline-derivative hypotensive agent; selective α2-adrenergic agonist. It stimulates alpha2-adrenergic receptors in the brainstem to decrease sympathetic nervous system outflow. It is also administered epidurally to treat pain. Microbeads offer numerous advantages for releasing one of the drugs or part of the same drug immediately while remaining drug or parts of the same can be sustained release. Prepared microbeads were evaluated for particle size, polydispersity index, zeta potential, particle shape, surface morphology, entrapment efficiency and In vitro drug release. The prepared beads were free flowing and white in color. The drug loaded beads showed 72.9±2.4% to 94.6±2.6 % drug entrapment, which was found to increase with increase in alginate concentration. In vitro drug release study of these microbeads indicated controlled release for Clonidine hydrochloride 83.46% release after 48 hours. Hence the observations of all results of the different batches, MBD 11 showed controlled release action and improved drug availability. From this study it could be concluded that the free flowing microbeads of Clonidine hydrochloride could be successfully prepared by ionotropic gelation technique with high entrapment efficiency and prolonged release characteristics.

Thermal shape fluctuation effects in the description of hot nuclei

The behavior of several nuclear properties with temperature is analyzed within the framework of the Finite Temperature Hartree-Fock-Bogoliubov (FTHFB) theory with the Gogny force and large configuration spaces. Thermal shape fluctuations in the quadrupole degree of freedom, around the mean field solution, are taken into account with the Landau prescription. As representative examples the nuclei $^{164}$Er, $^{152}$Dy and $^{192}$Hg are studied. Numerical results for the superfluid to normal and deformed to spherical shape transitions are presented. We found a substantial effect of the fluctuations on the average value of several observables. In particular, we get a decrease in the critical temperature ($T_c$) for the shape transition as compared with the plain FTHFB prediction as well as a washing out of the shape transition signatures. The new values of $T_c$ are closer to the ones found in Strutinsky calculations and with the Pairing Plus Quadrupole model Hamiltonian.Comment: 17 pages, 8 Figure
