In this work, the characteristics of AlGaAs film grown on transparent Al2O3 substrate are investigated. AlGaAs films having various Al compositions were fabricated on the GaAs buffer layer of an Al2O3 substrate using metal organic chemical vapor deposition. It was found that the crystal quality and surface roughness of the AlGaAs film was gradually improved by increasing the Al composition. The relatively improved surface and crystallizations were observed at AlGaAs film having an Al composition of 80%. A marked decrease in the d-spacing between the AlGaAs plane and Al2O3 substrate was clearly observed under the same condition. From these results, the high-quality AlGaAs film on the Al2O3 substrate was attributed to an increase in the substitutional effect of Al for Ga caused by increasing the Al composition.

Statistical analysis of ground water of kamleshwarpur area at Mainpat, was carried out to study the correlation between various physico-chemical parameters. Eleven water quality parameters of ground water of this area were estimated standard methods and procedures of sampling and estimation. pH of drinking water is an important parameter and it is correlated with ten parameters. It may be suggested that TH, Mg++,TDS, TSS and fluoride are positively correlated with pH but Conductivity, Total Alkalinity and Cl- are negatively correlated with pH. Calcium and Iron showed no relation with pH. The Iron value of ground water is also above the permissible limit.

Radon gas is colorless, odorless and tasteless and can only be detected by testing. It naturally occurs from traces of uranium in soils and rocks. It results from the decay of trace amounts of uranium, found in most rock and soil. It is measured using special monitors and expressed in units of bequerels per cubic metre (Bq/m3) or picocuries per litre (pCi/L). The air pressure inside the laboratory is usually lower than in the soil surrounding the foundation [4]. This difference in pressure draws air and other gases, including radon, from the soil into the atmosphere. The Uranium stays in the ground, but radon gas seeps upward and enters buildings. It can be used to predict the arrival of an earthquake. This is because radon is a radioactive gas and it can be traced by detecting alpha particles emitted during the decay of radon and its daughters. It can be achieved by using alpha sensitive solid state nuclear track detectors or some other suitable radon gas detectors.

The process of collaboration and technology transfer between university and industry in Nigeria cannot be effectively undertaken if there is no formal structure to promote interaction and communication between them. Research has shown that most universities in Nigeria are lacking in fundamental startups for collaboration with industry that is, research groups and facilities. This paper discusses the need for the establishment of a regenerative structure to enhance linkage between university and industry for the purpose of achieving the aforementioned aims. The paper also discusses the functions of various units comprising the regenerative structure and proposes a network of communication between them for effective technology transfer and innovation.

In this research we have proposed a new compression algorithm that used locational compression technique based on Freeman chain code. The technique consists of two parts, the first part is compression algorithm which starts by obtaining the chain code for particular color value then saving location of start point for chain code, color value and chain code in compressed file, the next step is to remove all color values that related to chain code from input image and shrink the input image, the algorithm repeats the previous procedures until there will be no color values with significant chain code. The second part is to construct the original image by using start point, color value and chain code.

The article deals with the use of activated water for drinking of pigs. Moreover, is described a method sonochemical activation of water. Sonochemical activated water is devoid of own supramolecular structure and has a high solvent power similar to how a boiling water, while remaining virtually the same temperature, which was prior to treatment. It is shown that the water in a thermodynamically nonequilibrium state, in which abideth some time as a result of such treatment, and has bactericidal and bacteriostatic properties, which it retains long time. All this suggests that the hydration of biopolymers directly into the esophagus and stomach of animals during their drinking will give tangible effect. Given the description of the mechanisms of cavitational disintegrated of water and described in comparison reactors for water treatment. Said that a regulatory authority in Russia give permission to use sonochemical technologies and devices in the food industry. Described sonochemical reactor, designed specifically for use in drinking of pigs, which have a reduced noise level and power consumption, but with better performance.

This study sought to investigate the effectiveness of the Early Childhood Development (ECD) programme on grade one performance in Mzilikazi District in Bulawayo. Papalia, Olds and Feldman (2001) observed that children who have been through ECD programmes generally excelled in basic academic skills while Smith (1994) suggested that ineffective ECD programmes led to fragmented and wide variation in the quality of early primary school education. The study was quantitative in nature and used a cross-sectional survey and the ex-post facto research designs. Two independent samples of 100 grade one children each, 20 grade one teachers and 10 administrators participated in the study. Mathematics and English Language self-designed tests were used with the children while structured questionnaires were used with teachers and administrators. Data were presented on tables and analysed using the Likert Scale, descriptive and inferential statistics. Indications from qualitative data were that the ECD programme was not effective on grade one performance in both subjects. A t-test of independent means confirmed that, there was no difference in performance in Mathematics between grade one children who underwent the ECD programme and those who did not. However, in English Language the t-test indicated a significant difference in performance between the two groups. On these bases, the research concluded that the ECD programme in Mzilikazi District was not effective on grade one performance in Mathematics but was effective on English Language performance. The study then recommended increased financial, material, human resource and infrastructural support of the ECD programme and review of the ECD curriculum

The paper focuses on simulation & analysis of a Rear Under Run Protection (RUPD) system under crash scenario. The basic objective is to improve the safety of the car and the occupants by designing the RUPD and car bumper. The choice of material and the structural design are the two major factors for impact energy absorption during a crash .The deformation of RUPD bar and plastic strains in RUPD components can be determined before the physical test for predicting failure of the system to meet the compliance requirements as per IS 14812-2005. Additionally, failure of the RUPD attachment points with chassis can be determined. Physical testing can be reduced significantly with this approach which ultimately reduces the total cycle time as well as the cost involved in product development. This project explains the FE analysis of RUPD for impact loading. All the results obtained from the impact load analysis are evaluated against the requirements of IS 14812-2005 which could reduce the process development time and cost involved in the same. The analysis was carrying out using Finite Elements software (LS-Dyna), Meshing tools by Altair Hyper mesh and Modeling on Pro-E. This analysis is a partial work of a major project wherein the RUPD will be subjected to static testing with variable load distributions at different locations on RUPD. The analysis establishes the method and parameters of the simulation on modeling and analysis software used by demonstrating the energy absorption pattern in bumper and RUPD during frontal crash of a car with different design parameters of RUPD.

Matrix Multiplication is one of the most commonly used algorithm in many applications including operations on Relations in Relational Database System. In this paper we study and evaluate the execution time of matrix multiplication on a single, dual and multi-core processor with same set of processors having OpenMP(Open Multi-Processing) libraries for C-Language. OpenMP is a very well known standard that exploits parallelism in shared memory architecture. The evaluation is based on execution of the algorithm uses single thread for computation whereas the one with OpenMP uses multi-threads.
