Solar parabolic trough collectors are the most useful technology that directly supports renewable energy for conventional energy for water heating. But it is observed that due to ambient temperature many convective losses occur which effects the temperature variation. This article shows the practical work for increasing temperature to cover it by thin transparent glass plate which creates the oven effect and decreases its convective losses which increases the temperature and finally it increase its efficiency.

Lack of good research proposal and its presentation is a growing concern in academics researches worldwide. This has been linked to increased poor research writing skills and unavailability of relevant materials including presentation and interpretations of researches. What makes a good research proposal and the basic ideas and steps of the research proposal in scientific investigations were lacking also. The nature, scope and role of research proposal was conceived with the mind to attempt to overcome this non-unique approaches into researches but from different disciplines by providing a-one-stop article for good research proposal writing and presentation. In order to get the above fulfilled, the concept and procedures of good research proposal writing were examined and explained. The basic steps and the importance of research proposal were equally outlined. Good examples were used in illustrations and recommendations were also advanced.

Granule size is used as a parameter and as a quality specification by manufacturers while designing a cost- effective prilling tower for obtaining a standard granule size. In this study, we obtained a standard 2 mm diameter granule using an alternate prilling method other than those available in the industry.

Black liquor the main waste remained from paper industry composed mainly of some organic compounds as a soluble salts and a high portion of sodium silicate. The idea of this paper is to transfer the inorganic part from this waste into useful product (calcium silicate hydrate) which has a lot of known applications nowadays. The preparation of calcium silicate from black liquor was done through direct reaction between the black liquor, calcium carbonate and calcium hydroxide and boiling for about 2 hrs. This method was known as hydrothermal method. The obtained materials as well as the raw materials were investigated using both IR and XRD analyses.

The nutrient composition of processed minor millets was investigated by various cooking methods like wet heating (boiling, blanching, soaking and germination) and dry-heating (roasting) and to compare the antioxidant activity of processed minor millets in relationship with their total phenolic content. Foxtail and proso millet were subjected to different processing methods; samples were dried and powdered into fine flours, respectively. Standard methods were used to evaluate the flours for moisture, ash, protein, fibre, iron, phosphorus, calcium, magnesium and zinc. The antioxidant activity was estimated with respect to DPPH radical scavenging activity; FRAP assay and reducing power method. The soaked samples of foxtail and proso millet showed higher scavenging activity which was found to be (51.06% and 52.12%) respectively. The antioxidant power of roasted foxtail millet and blanched proso millet had significant increase ranging about (317.5 ? mol and 236.8 ? mol) respectively using FRAP assay. The blanched samples had higher reducing power indicating enhanced antioxidant activity i.e. (0.426 and 0.418) respectively. The phytochemical content was determined qualitatively. The blanched and germinated millet samples possessed higher antioxidant activity.

There has been an increasing level of interest, among government and industry constituents, in the growth of the SME sector in India. There is today a recognized need felt for the transformation of firms in this sector from a hitherto ‘family-owned-and-run’ orientation to a more ‘professionally managed’ one. This transformational process unfolds several challenges to the organizations in the SME sector. This exploratory study, on a sample of auto-components firms in the SME sector, located in the Tamilnadu Capital Region of Chennai, has the objective of furthering our understanding of the specific challenges faced by these organizations. The case-study method has been used to carry out this study. Areas in this sector that need immediate attention have been identified. A couple of propositions based on this study, related to the source of organizational transformation and to the major challenge to firms in this industry, have also been put forth.

The study was designed to investigate the perceptions of university teachers for feasibility of problem based learning at university level. Being a descriptive study a questionnaire was used as a tool to acquire perceptions of university teachers regarding feasibility of problem based learning at university level. A purposive sample of 23 university teachers from two departments i.e. Education & Mass communication at university was selected including some senior faculty members. Participants were with different qualifications which ranged from masters to MS/PhDs. Data was analyzed through descriptive statistics and by calculating a t-test to determine the difference of perceptions among university teachers in view of their gender. Results indicated a strong perception of university teachers about effectiveness of problem based learning on student. It was also found that university teachers were having strong perceptions about initiation of problem based learning at university level. There was no significant difference about perceptions of teachers in view of their gender. Necessary changes in curriculum, assessment procedures, training of staff, administrative needs and raising of financial resources were recommended for initiation of problem based learning at university campus.

Identifying Points of Difference (POD) is a challenging task for any brand manager. Though Points of Parity (POP) can be easily identified, research needs to be undertaken to identify distinguishing points of difference. In order to get a view of how customers perceive different brands on various parameters perceptual mapping can be used. This paper studies the use of attribute based perceptual mapping for major mobile service provider brands. Three major attributes were identified namely; Service quickness, Service friendliness and Service fairness and these attributes were used to create a perceptual map and to identify which mobile service provider brand fares better in a multidimensional space.

Pooled confirmatory factor analysis (CFA) for wellness perception (PK) emotional intelligence (KE) spiritual intelligence (KS) counseling self-efficacy (EKK) and self-development (PD) of the public university’s counselor trainees were done using IBM_AMOS Version 21.0. A total of 208 respondents, who are trained counselors from Bachelor Degree in Counseling, was involved in the research which currently undergoing internship training. needs to validate all the latent construct measurement model for unidimensionality, validity and reliability.

The employability skills are regarded as valuable in employment success. The application of employability skills in the present and future workplaces also facilitates employees’ job performance. Explanatory correlational research design was used in the study which was aimed at determining the relationship between the practice of employability skills and contextual performance of employees. Drawn from The Conference Board of Canada’s Employability Skills 2000+ and Borman and Motowidlo’s Taxonomy of Contextual Performance, two sets of survey questionnaires were adopted to collect data from 220 sampled respondents representing employers and employees of 25 government institutions in Central Mindanao region of the Philippines. Results showed that government employees practiced fundamental, personal management and teamwork skills to some extent. Also, these employees demonstrated satisfactory contextual performance as perceived by the two groups of respondents. Moreover, inferential analysis revealed that practice of employability skills had significant moderate positive relationship to contextual performance. The use of employability skills, therefore, needs to be sustained to pave way to improved extra-role behaviors that help meet the requirements and demands of public institutions
