The structural adjustments programmers adopted in a number of countries have brought home the vulnerability of human development variables. The linkages between investments in human development programmes and economic development have become sharper. There have been major international developments-such as the opening of global markets, the increased market orientation of economies and the restructuring in socialist countries-which have given rise to an increased competition, forcing developing countries to produce and market quality products at competitive prices.

Investing in education is imperative in this knowledge based economy to sustain a competitive edge. As we are aware, the higher education level is a significant factor for a long term economic growth. To ensure students’ are well equipped with the foundation for a higher level, a proper transition from primary right up to tertiary is crucial. In retrospect, poor achievement in higher learning institution has been an invariable issue and has drawn the attention of the higher learning institution, especially in numerical subjects like the College Mathematics. Although research of the higher learning institution places emphasis on classroom intervention to enhance students’ achievement, a study in the phenomenon from the perspective of course setting of the high school level mathematics education as reason behind poor performance in college is also vital. The aim of this study was to investigate the influence of students’ performance in high school Mathematics on students’ academic performance in College Mathematics. The respondents of this study were the students from a private college. This study revealed that performance in high school Mathematics has an association with student’s performance in College Mathematics, while gender and medium of study act as moderators.

The prevention climatic changes induced by anthropological greenhouse gas emissions, is one of the of severe major challenges for the current and future generation of mankind hence this study investigates in providing a cheaper and cleaner fuel in burning from post harvesting agricultural wastes. Coal and wood have been the primary fuel used subsequently and produce lot of polluting gases like carbon monoxide, sulphur dioxide, carbon dioxide which has consequences on health. The agriculture waste is bio degradable and decomposes/burns. Since waste can be a source of energy after mixing the waste material of different calorific value, the agriculture waste can be converted into fuel cakes or by modifying charcoal by destructive distillation process by using of effective carbonizer. The results obtained with multifuel (Agri charcoal) further stronger the idea of setting small power plants, dedicated to rural sector of India.

Cloud computing is an efficient data sharing technique where users can directly store and access information through internet. Hence the chances of unauthorized access and security of data is an important issue in cloud computing, hence various techniques are implemented for the security of cloud data. Encryption is a technique of providing a secure access of data over internet, but chances of attack is still possible. Hence an efficient technique is implemented using the concept of multi-keyword based data retrieval in cloud computing with encryption [1]. Although the technique is efficient in terms of communication overhead and security from various attacks but further enhancements can be done in the technique to make it for secure and easy, hence a new and efficient technique is implemented in cloud computing using attribute based encryption and verification, the proposed technique implemented provides security from various attacks and provide less storage and communication overhead.

During this last decade, mesh networks have experienced strong growth due to their ability to provide an additional and complementary support for existing infrastructure communication systems. In such a network, routers are supposed to be fixed for short (e.g. public safety deployment) or long (e.g. network operator extension) period. This relative stability of infrastructure makes proactive routing protocols appropriate. One of the well known proactive routing protocols is OLSR (Optimized Link State Routing), which routing decisions are based on exchanges of topology information using all-to-all flooding of local information in order for each router to build a global knowledge of the topology. This study first goal is to improve the performance of topology information flooding in OLSR by introducing network coding techniques, which leads to a decrease of signaling overhead.

The leaves extract of abutilon indicum leaves herbal preparation that has been suggested as useful in the treatment of varies diseases anti microbial, anti wound killing agents and anti oxidant etc. In this study to determine the gastro protective effect of abutilon indicum leaves in a model of Indomethacin induced ulcer rat. The extract was given by oral gavages (100 and 200mg/kg) three times at 12 h intervals after administering indomethacin 30mg/kg. Treatment with the extract resulted in a significant decreased of the ulcerated area. The results were comparable with the positive control (ranitidine 50mg/kg). Further the results were confirmed using Histopathological studies of the stomach. Thus, we concluded that hydro-alcoholic extract of abutilon indicum leaves possess good preventive and therapeutic action on the gastric ulcers.

Maximising academic learning time has been identified as a critical tool for improving student achievement. The study aimed at assessing factors that influence the utilisation of teaching time allocated to primary schools, how distortions in the allocated time affect teaching curriculum, and measures in place to ensure that instructional time is efficiently utilised in schools within the Sekondi-Takoradi Metropolis. Descriptive research design was adopted for the study. Stratified sampling procedure was used to sample 63 respondents. Questionnaire and observation guide were used as instruments for collecting data. SPSS version 17 and Microsoft Excel 2007 Edition were used to analyse the data. Descriptive statistics, chi square and one sample t-test were used to describe the data.

Black Carbon (BC) in PM2.5 and PM10 concentrations in Ashaiman, a semi-urban area of Ghana, were determined in 2008 using IVL PM2.5 and PM10 particle samplers. The aerosols were sampled on Teflon filters for three months, and the particulate mass PM2.5 and PM10 determined by gravimetrical method. Aerosol filters were analyzed to determine BC concentration levels using the black smoke method. PM2.5 mass concentrations determined averaged 23.26µg/m3 (3.85 - 46.43 µg/m3) and that of PM10 was 96.56µg/m3 (37.10 - 293.06 µg/m3). For fine particulates (PM2.5), the contribution of BC have been found to be about 18% of the total mass, while for particulate matter PM10, it has been found to be about 4% , its averaged 2.83µg/m3 (1.67-4.89µg/m3) for PM2.5 and 3.98µg/m3( 1.99-12.44µg/m3) for PM10. The results were compared with some literature values and World Health Organization guideline values. The mean 24-h BC values for the particulate mass varied daily and shows that the semi-urban background during the period, not only involved combustion activities which are largely responsible for the PM2.5 particulate matter but also involved in other man-made or natural activities that resulted in the high value of PM10.

To help the user to cope with such a variety of interfaces, instance types, and pricing models, cloud brokers have emerged as a powerful tool to serve as intermediary between end users and cloud providers. A cloud broker can provide a uniform interface independently of the particular cloud provider technology, can collect automatically information from providers (instance availability, prices, etc.), and can help cloud users to choose the right platforms when deploying their services across multiple clouds, also allowing them to switch between platforms to get the best conditions.

The aim of this paper is to explore the diasporic sensibilities of Jhumpha Lahiri as demonstrated through the culinary montage she appends to the retrospection of her life and history narrated in her anthology of short stories titled Interpreter of Maladies. The article highlights how Indian women living abroad find difficult to shed off the memories of their native land during their process of assimilation. To camouflage her apprehension of losing her identity and ameliorate her sense of dislocation in a foreign land, Jhumpha Lahiri persistently makes references to Indian food habits and culinary skills. Further she reminisces of rituals practised in the kitchen room and uses excessive food imagery to substantiate the physical and psychical conditions of Indian men and women and also to evaluate their intensiveness of relationship- cordial or complicated.
