Heart Attack and other cardiac diseases have shooted up the death rate in the world in recent years. So they have to be given more importance. Though the Heart transplantation techniques has originated in 1960’s it gained popularity only in 1980’s, after the invention of Anti Rejection Medicine. Now the advancement is such that, the patient’s old heart ECG can alone be monitored by suppressing the interference arising from the new heart, which ease the job of the surgeon, which can be achieved using Adaptive Noise Cancellation Technique. The algorithms such as LMS and RLS were implemented using MATLAB 6.5 and simulated and synthesized using Modelsim and Leonardo spectrum VLSI tools. In future the design will be fused into a chip and dedicated to mankind.

In order to success in removing stains from historical dyed samples, it is necessary to understand the nature and type of these stains. This research work aimed to study in detail the different changes occurring on mimic cotton carpet samples dyed with natural yellow dye turmeric and subjecting to different stains (blood, mud and wax). All the stained samples were subjected to light ageing followed by cleaning with different detergents according to the nature of the stain. The examined samples were characterized and evaluated using FTIR-ATR analysis to examine the change in the chemical structure after each treatment process and studying the effect of such processes on the crystallinity/amorphousity of the samples. Also, the color measurement in the CIELAB system was used to quantify the change in samples' colors through the different treatments. The obtained results indicated that: there was an obvious change in the transmission peak intensities of the different functional groups after each treatment, a variation in both the crystalline index (C.I) and % crystallinity of the examined samples and the cleaning process greatly depends on both the type of stain and the cleaning material.

This study was undertaken to assess the characteristics of solid waste generated in the three campuses of the university viz Abuja, Delta and Choba campus. Open dumpsites were identified in each campus and a representative sample of solid waste (5kg) was obtained. The results showed that food waste contributed the highest percentage composition of 35.9% in Choba followed by Abuja (25.49%) and Delta Park (17.39%). Paper had the highest percentage composition of 26.45% in Delta Park, followed by Abuja Park (23.14%) and Choba (10.71%). Wood had the least composition of 1.96% in Abuja Park but absent in Delta and Choba Park. The results further showed that food waste had the highest composition of M.S.W generated in Choba (Weight kg) 3.55, followed by Abuja Park (2.6) and Delta Park (2.1) while wood had the least weight generated of 0.20 in Abuja Park and absent in Delta and Choba Park. The data analysis revealed that there was no significant difference in the composition of waste in the different campuses at p<0.05. It is believed that given the characteristics of these waste streams, an integrated solid waste management system in the University will enhance the adequate utilization of the various categories of solid waste in the areas of resources, recovery and waste-to-energy.

Banana bunchy top virus (BBTV) is a destructive pathogen in banana cultivating areas worldwide. As the virus is located in the phloem tissue and its purification is difficult and gives low yield. Therefore, in the present study BBTV coat protein was bacterially cloned and expressed using recombinant DNA approach. The BBTV infected banana leaf samples were collected around Uttar Kannada district of Karnataka. Further, the total nucleic acid was extracted using dellaporta method. A 531bp PCR product containing coat protein coding region of BBTV was amplified using BBTVCPF and BBTVCPR primers and the amplified product was cloned into the pTZ57R/T and further sub-cloned in to the pQE30. After transformation in to JM 109 and M15 cells the clones were confirmed through PCR and sequencing. Amplification with expected size of 531bp and 100% homology with other isolates showed integrity of the clone. Further, the coat protein appeared to be expressed at 3hr after induction with 1mM IPTG. The expressed protein was analyzed through sodium-dodecyl sulphate-Poly acrylamide gel electrophoresis (SDS-PAGE). A band of 21kDa on the gel confirmed that coat protein was really fused to the His-tag. Further, 10mg/liter of the coat protein were purified using His-tag purification kit (Genei).

Cognition is the mental processing that includes the attention of working memory, language comprehension, reasoning, etc. Reading is a basic and essential skill and has its own set of cognitive advantages which includes; the ability to empathize, reduction in stress levels, better analytical skills, etc. In the novel To Kill a Mocking Bird, Atticus Finch is a character who indulges in the seraphic pleasure of reading. The paper aims at bringing out how reading visibly impacts his character, as he stands juxtaposed in myriads of arenas, to the people of his race. Scientists have conducted a detailed research and have declared that reading has the following advantages.

An attempt has been made to evaluate the effect of surface roughness and deformation on the performance of a magnetic fluid based squeeze film in rough porous circular plates considering porous matrix of variable thickness. The stochastic model of Christensen and Tonder has been adopted to characterize the roughness of the bearing system. With appropriate boundary conditions, the associated Reynolds’ type equation has been solved by invoking the dilog function, to derive the expression for pressure distribution resulting in the calculation of load carrying capacity. It is observed that the adverse effect of transverseroughness gets aggravated due to the bearing deformation. But the situation remains fairly improved in the case of negatively skewed roughness for a large range of bearing deformation with a suitable strength of the magnetic field. Further, it is appealing to note that this positive effect gets augmented with a proper selection of thickness ratio parameter associated withvariable film thickness.

India has come a long way from being called the ‘land of snake-charmers’ to one of the fastest developing countries of the SAARC region. Having seen the rise and fall of many a kingdoms and being ruled by many, India has soaked up the essence of almost every dynasty resulting in a rich cultural milieu which manages to enthrall everybody. Post independence, India witnessed the drafting of the Constitution which pronounced India as a ‘Sovereign, Socialist, Secular, Democratic, Republic’ and as a newly emerged welfare state. Since then and after 66 years of Independence, India has been growing steadily though not without challenges. To contextualize this article, we can argue that the health care system of India has been facing many challenges in terms of the perspective of being user friendly and distributed equitably, to favor all the sections of the society equally. Widespread loopholes have been noticed in the delivery of the health care system in India. Availing quality health care has now become the prerogative of only the well to do section of the society, leaving the marginalized section of the society at the mercy of governmental setups which are drowned in their own incompetence and corruption therefore failing to provide quality health care to the society. This paper proposes to take a look at these existent inequalities in the delivery of the health care system. In this effort data has been collected from 6 districts of Karnataka, 3 of which are rural districts and 3 of which are urban. Rural and urban districts are operationally understood as 3 districts each having lowest HDI and 3 districts having the highest recorded human develop index (HDI) of Karnataka respectively. High human development Index (HDI) is being represented by Bangalore, Udupi and Mangalore consisting of 1136 people interviewed in total, whereas low level of HDI is represented by Raichur, Chamarajnagara and Gulbarga, with a total of 1327 respondents.

The thermal performance of tractor radiator is improved with Cu/water when compared with CuO/water nanofluids as workings fluid. The nanomaterial plays a vital role for past two decades in the research areas like thermal management and material science. Miniaturization and increased operating speeds of heat exchangers warranted the need for new and innovative cooling concepts for better performance. The nano materials and its suspension in fluids as particles have been the subject of intensive study worldwide recently since pioneering researchers recently discovered the anomalous thermal behavior of these fluids. For heavy vehicles the engine cooling is an important factor for their performance in the intended application. Here the tractor engine radiator cooling is enhanced by nanofluid mechanism of heat transfer for its improved performance in agricultural work. If the tractor engine cooling is enhanced then using this farm equipment more agricultural field can be ploughed which can be utilized for cultivation within a short period of time. Heat transfer in automobile is achieved through radiators. In this research work an experimental and numerical investigation for the improved heat transfer characteristics of a radiator using Cu/water and CuO/water nanofluid for 0.025, 0.05 and 0.075% volume fraction is done with inlet temp of 50 - 60°C under the turbulent flow regime (8000 ? Re ? 25000). The overall heat transfer coefficient decreases with increase in nanofluid inlet temperature of 50 - 60°C. The experimental results of the heat transfer using the Cu metal particles of nanofluid is compared with Oxide and the numerical values which shows an increase in heat transfer coefficient. The results in this work suggest that the best heat transfer enhancement can be obtained compared with the base fluid and oxide form by using a system with Cu/water nanofluid-cooled radiators. The nanofluids showed better heat transfer characteristics as a new alternative coolant for the radiator.

No story is ever told as if it is the only one; the subtext changes as time passes by. It can have a number of meanings, explanations, understandings, and interpretations according to its context and readers. Consequently, appreciation of any literary work may have its own evolution in course of time. The possible plurality of meaning leads into the maze of meaninglessness of meanings. This indeterminacy of meaning requires deconstruction of the text and its structure and reconstruction of it to find an appropriate meaning. The works of very many authors apparently seem to be in the same meaningless level. It is the researcher’s task to find meaning to this meaninglessness of meanings. The works of Bertolt Brecht, the German playwright are not an exception to this task. His complex artistic works require deep study and careful analysis to arrive at new understanding. In short, they require complex seeing. Brecht’s plays grapple with some of the intense situations of life as lived in different societies. Some of his leading concerns are issues derived from religion, war, capitalism, motherhood and rebellion. This article investigates the theme of religion in the selected plays with the tool which Brecht himself has expected from his audience - complex seeing.
