Effect of Regional Dialects in Learning Tamil Language

Having two forms of practice, the spoken and written, is a peculiarity that the Tamil language has. In written form the language is used with no grammatical errors. Spoken form is the one that people use in their daily language as they speak. This colloquial usage is most importantly used to express human emotions. It can be observed that, spoken form of language and the pronunciation of words differ according to region, race and caste. The word is subject to change depending upon these factors while the meaning remains constant. When a word differs from the common usage based on the region, race or caste it is called as a regional dialect. Tamil language is considered to be the oldest language, the one that man spoke first. It has a rich sense of nativity and intellectual depth. Language is not just a medium, it is also an identity for the race that used it. It becomes our responsibility to document it. Regional dialects are assets to a language. While teaching such language, along with teaching the meaning of lessons, vocabulary and its usage should also be taught in order to have a deeper understanding about the taught meaning. Only then Tamil’s richness could be internalised.  A teacher should elaborate the influence that regional dialects have on a language, in order to make the process of language learning fruitful. A child’s primary learning begins at home before it steps into a school. This research article reflects the impacts that understanding the changes in people and their language while exposed to the external environment from home environment has on the process of learning

Radiation and Chemical Reaction Effects on MHD Thermosolutal Nanofluid Flow over a Vertical Plate in Porous Medium

In this study we discussed the influence of radiation and chemical reaction on MHD thermosolutal nanofluid convective slip flow over a vertical plate in porous medium in presence of thermophoresis and Brownian motion effects. The governing boundary layer partial differential equations are transformed into system of ordinary differential equations by using similarity transformation and then solved numerically using bvp5c Matlab package. The effects of dimensionless governing parameters on the flow, heat and mass transfer was discussed and presented through graphs. Also, the skin friction coefficient and local Nusselt and Sherwood numbers are computed and discussed. Results indicate that an increase in chemical reaction parameter enhances the mass transfer rate. Keywords: MHD, Radiation, Chemical Reaction, Nanofluid, Convection

Influence of Aligned Magneticfield on the Flow through Vertical Surface in Porous Medium with Heat Source

In this paper we analyzed the influence of aligned magneticfiled, radiation and chemical reaction on the flow through vertical surface in porous medium in presence of heat source. The governing partial differential equations are reduced to ordinary differential equations and solved numerically by using Shooting technique with Matlab Package. The effects of non-dimensional governing parameters on the flow, heat and mass transfer are discussed and presented with the help of graphs. Also, coefficient of skin friction, Nusselt and Sherwood numbers are discussed and presented through tables. Comparisons of the results with the existed studies were presented. Present results have an excellent agreement with the existed studies under some special conditions. Keywords: Radiation, Aligned magneticfiled, Chemical reaction, Heat source, Dissipation

Nonlinear Thermal Radiation and Chemical Reaction Effects on MHD 3D Casson Fluid Flow in Porous Medium

In this study, we analyzed the influence of nonlinear thermal radiation and viscous dissipation on three-dimensional MHD Casson fluid flow over a stretching surface in the presence of chemical reaction. The transformed governing equations are solved numerically using Runge-Kutta based shooting technique. The influence of non-dimensional parameters on velocity, temperature and concentration profiles along with the friction factor, local Nusselt and Sherwood numbers are discussed with the help of graphs and tables. It is found that an increase in the nonlinear thermal radiation parameter enhances the temperature profiles of the flow.  Chemical reaction parameter have tendency to enhance the mass transfer rate. Keywords: MHD, Casson fluid, Radiation, Chemical Reaction, Dissipation

Evaluation of various methods of susceptibility to ofloxacin in strains of Mycobacterium tuberculosis

A comparison of three methods of susceptibility testing was undertaken on 30 susceptible and 25 resistant strains of Mycobacterium tuberculosis to determine an acceptable in vitro definition of resistance of ofloxacin. The strains were tested by the proportion method on Lowenstein Jensen (L-J) and 7H11 media and also by the BACTEC radiometric method. Using a criterion of 1 per cent or more growth at a concentration of 2 mg/1, there was a 100 per cent agreement with the conventional MIC method by the proportion tests on L-J as well as on 7H11 media. The BACTEC radiometric method, at the same concentration, yielded 98 per cent agreement. Thus, any of these methods could be used depending upon the infrastructure available

Nocardia bacteraemia in an HIV-positive patient - a case report

Nocardiosis has been recognized in recent times as an unusual opportunistic infection associated with HIV. Bacteraemia due to this pathogen is even rarer and only few cases have been reported in the literature. We report here a case of pulmonary nocardiosis with bactcracmia, which was initially diagnosed as pulmonary tuberculosis. A high index of suspicion is required to diagnose this infection as the clinical presentation and radiographic features mimic pulmonary tuberculosis
