Effect of Deformation on Semi–infinite Viscothermoelastic Cylinder Based on Five Theories of Generalized Thermoelasticity

We considera dynamical problem for semi-infinite viscothermoelastic semi infinite cylinder loaded mechanically and thermally and investigated the behaviour of variations of displacements, temperatures and stresses. The problem has been investigated with the help of five theories of the generalized viscothermoelasticity by using the Kelvin – Voigt model. Laplace transformations and Hankel transformations are applied to equations of constituent relations, equations of motion and heat conduction to obtain exact equations in transformed domain. Hankel transformed equations are inverted analytically and for the inversion of Laplace transformation we apply numerical technique to obtain field functions. In order to obtain field functions i.e. displacements, temperature and stresses numerically we apply MATLAB software tools. Numerically analyzed results for the temperature, displacements and stresses are shown graphically

Expression of genes related to Na⁺ exclusion and proline accumulation in tolerant and susceptible wheat genotypes under salt stress

In the present investigation, expression of genes related to Na+ exclusion such as salt overly sensitive (TaSOS1) and Na+/H+ antiporter (TaNHX1) and proline accumulation such as pyrroline-5-carboxylate reductase (P5CR) and glutamate synthase (GOGAT) was studied in seedlings of Kharchia 65 (Kh 65, salt tolerant) and HD 2009 (sensitive) under salt stress (ECe, 12 dSm–1) and controlled conditions. As compared to HD 2009, Kh 65 showed significantly lower accumulation of Na+ (p + exclusion in root and compartmentation in leaf and increased proline concentration are associated with tolerance to salinity stress in wheat. The information will be useful for improving wheat genotypes for salt tolerance

Synthesis, Spectral, and Biological Properties of Copper(II) Complexes of Thiosemicarbazones of Schiff Bases Derived from 4-Aminoantipyrine and Aromatic Aldehydes

We have synthesized a novel series of Schiff bases by condensation of 4-aminoantipyrine and various aromatic aldehydes followed by reaction with thiosemicarbazide. These thiosemicarbazones are potential ligands toward transition metal ions. The reaction of copper(II) salts with 4[N-(benzalidene)amino]antipyrinethiosemicarbazone (BAAPTS), 4[N-(4′-methoxybenzalidene) amino] antipyrinethiosemicarbozone (MBAAPTS), 4[N-(4′-dimethylamino benzalidene) amino] antipyrinethiosemicarbazone (DABAAPTS), and 4[N-(cinnamalidene) amino] antipyrinethiosemicarbazone (CAAPTS) resulted in the formation of solid complexes with the general composition CuX(2) · (H(2)O)(L)(X = Cl, Br,NO(3),NCS, or CH(3)COO; L = BAAPTS, MBAAPTS, DABAAPTS, or CAAPTS). These complexes were characterized through elemental analysis, molecular weight, electrical conductance, infrared, electronic spectra, and magnetic susceptibilities at room temperature. Copper(II) complexes with BAAPTS and MBAAPTS were screened for antibacterial and antifungal properties and have exhibited potential activity. Thermal stabilities of two representative complexes were also investigated

A descriptive analysis of patients admitted in short stay ward at psychiatric centre, Jaipur, Rajasthan, India

Background: The average length of stay (LOS) at psychiatric centre and the factors determining longer LOS in Psychiatry disorders remains largely unexplored. Longer LOS is associated with social isolation and maladaptive behaviours in patients thus warrants a shorter stay. The observed LOS and predicted LOS among different psychiatry hospitals in future may serve as an index of quality care and efficient management of meagre but available resources in our country. The aim was (1) To study the socio demographic and clinical factors of patients admitted at our hospital and (2) To ascertain the relationship between the socio demographic, clinical factors and LOS.Methods: A retrospective analysis of psychiatry inpatients admitted at Psychiatric Centre, Jaipur during July 2014 and June 2015. The data was analysed studying the 489 case records. The socio demographic characteristics and clinical factors were correlated with LOS in hospital.Results: Our study has shown the correlation of socio-demographic factors and clinical factors with LOS. Rural population, marital status, employment status, number of episodes and diagnosis itself has positive correlation with longer LOS.Conclusions: From present study it was shown the correlation of socio-demographic factors and clinical profile with LOS. Rural population, marital status, premorbid employment status, number of episodes and diagnosis itself has positive correlation with longer LOS. However, gender and substance abuse had no correlation with LOS. Short term and planned admissions along with individualized treatment plans fitting patient’s social background may be more beneficial as compared to long term admissions

Amplified fragment length polymorphism of clinical and environmental Vibrio cholerae from a freshwater environment in a cholera-endemic area, India

<p>Abstract</p> <p>Background</p> <p>The region around Chandigarh in India has witnessed a resurgence of cholera. However, isolation of <it>V. cholerae </it>O1 from the environment is infrequent. Therefore, to study whether environmental nonO1-nonO139 isolates, which are native to the aquatic ecosystem, act as precursors for pathogenic O1 strains, their virulence potential and evolutionary relatedness was checked.</p> <p>Methods</p> <p><it>V. cholerae </it>was isolated from clinical cases of cholera and from water and plankton samples collected from freshwater bodies and cholera-affected areas. PCR analysis for the <it>ctxA, ctxB, tcpA, toxT </it>and <it>toxR </it>genes and AFLP with six primer combinations was performed on 52 isolates (13 clinical, 34 environmental and 5 reference strains).</p> <p>Results</p> <p>All clinical and 3 environmental isolates belonged to serogroup O1 and remaining 31 environmental <it>V. cholerae </it>were nonO1-nonO139. Serogroup O1 isolates were <it>ctxA, tcpA </it>(ElTor), <it>ctxB </it>(Classical), <it>toxR </it>and <it>toxT </it>positive. NonO1-nonO139 isolates possessed <it>toxR</it>, but lacked <it>ctxA </it>and <it>ctxB</it>; only one isolate was positive for <it>toxT </it>and <it>tcpA</it>. Using AFLP, 2.08% of the <it>V. cholerae </it>genome was interrogated. Dendrogram analysis showed one large heterogeneous clade (n = 41), with two compact and distinct subclades (1a and 1b), and six small mono-phyletic groups. Although <it>V. cholerae </it>O1 isolates formed a distinct compact subclade, they were not clonal. A clinical O1 strain clustered with the nonO1-nonO139 isolates; one strain exhibited 70% similarity to the Classical control strain, and all O1 strains possessed an ElTor variant-specific fragment identified with primer ECMT. Few nonO1-nonO139 isolates from widely separated geographical locations intermingled together. Three environmental O1 isolates exhibited similar profiles to clinical O1 isolates.</p> <p>Conclusion</p> <p>In a unique study from freshwater environs of a cholera-endemic area in India over a narrow time frame, environmental <it>V. cholerae </it>population was found to be highly heterogeneous, diverse and devoid of major virulence genes. O1 and nonO1-nonO139 isolates showed distinct lineages. Clinical isolates were not clonal but were closely related, indicating accumulation of genetic differences over a short time span. Though, environment plays an important role in the spread of cholera, the possibility of an origin of pathogenic O1 strains from environmental nonO1-nonO139 strains seems to be remote in our region.</p

Synthesis, Biological, Spectral, and Thermal Investigations of Cobalt(II) and Nickel(II) Complexes of N-Isonicotinamido -2′,4′-Dichlorobenzalaldimine

A new series of 12 complexes of cobalt(II) and nickel(II) with N-isonicotinamido-2′,4′-dichlorobenzalaldimine (INH-DCB) with the general composition MX(2) · n(INH-DCB) [M = Co(II) or Ni(II), X = Cl(−) ,Br(−), NO(3)(−), NCS(−), or CH(3)COO(−), n = 2; X = ClO(4) (−), n = 3] have been synthesized. The nature of bonding and the stereochemistry of the complexes have been deduced from elemental analyses, infrared, electronic spectra, magnetic susceptibility, and conductivity measurements. An octahedral geometry has been suggested for all the complexes. The metal complexes were screened for their antifungal and antibacterial activities on different species of pathogenic fungi and bacteria and their biopotency has been discussed

Assessment of Biomass Potential in Engine Emission Reduction

77-80The twin crisis of environmental degradation and fossil fuel depletion has confronted the world with the upcoming threat to seek the solution for some alternate fuel. The present condition of environment forces the search of some suitable alternate fuel. The present degradation of environment is also mainly influenced by the diesel vehicles. The emissions released by these diesel vehicles not only degrade the environment but also increase the number of health diseases. The present research on bio-fuels will lead to develop a sustainable solution to this problem and also create a harmonic relationship between the economy and ecosystem. The present research will provide the optimized blending ratio compression ratio and other operating parameters to be selected while approaching to sustainable output. The present study will depict the behavior of different bio-fuels poured in VCR engine at different compression ratio at different operating parameters. The outcomes of this research paper reveals the discussion on the potential assessment of different biofuels in the reduction of engine emissions
