The major purpose of this study is to find out the extent to which previous knowledge of Book-keeping will predict students’ academic performance in Principles of Accounts 1 (BED 111) at the NCE 100 level in College of Education, Ikere Ekiti, Ekiti State, Nigeria. The study employed an ex-post facto research design with a sample of 371 selected from a population of 708. Three research hypotheses were tested at 0.05 level of significant using T-test, Standard deviation, Multiple regression and Analysis of variance. A finding from the study reveals that previous knowledge of Book-keeping significantly contributes to the prediction of academic performance of students in Principles of Accounts 1 (BED 111) among others. It was concluded that the influence of previous knowledge in teaching/learning process provides the background to framework upon which new learning will be placed. It is recommended that Joint Admission Matriculation Board (JAMB) should properly streamline
this study was undertaken for the purpose to determine the concentration of caffeine in eight brands of soft drinks with the use of an Ultraviolet spectroscopy. This told us about the best brand among the different brands containing caffeine. The highest concentration of caffeine was found in Sting 500mL (560.29 µg/mL), so it is strongest CNS (central nervous system) stimulant among all samples and it is harmful for health. The lowest concentration of caffeine was found in 7up 500mL (29.71 µg/mL). So it is a weakest stimulant among all samples and can be sold in market
Purpose: To determine the clinical relevance of determining the semen pH during semen analysis as per WHO (World Health Organisation) standard criteria among the infertile couple attending a tertiary ART (Assisted Reproductive Technology) Centre in South India. Methods: Regular Semen analysis as per WHO standards (2010) Results: The Semen pH value showed no major correlation with other Semen parameters and also varied greatly from the given WHO standard. Conclusion: The semen pH determined during semen analysis is found to have not much relevance for clinical practice. The clinical relevance of semen pH for Azoospermia patient needs to be revised.
wastewater is the harmful for the surroundings and it is released from commercial, domestic or public waste materials, the wastewater treatment companies needs to take care of wastewater.water treatment plant is also known as sewage treatment plant. there are many procedure of waste water treatment that are categorized in different groups. The main purpose of water treatment companies is to prepare chemical method which help to remove waste products form water for its purification.Aqua pristine are well known supplier and manufacturer of sewage treatment plant. we have professionally water treatment experts which specialist in water purification system.we set up wastewater and sewage treatment plant for different types industries.
The purpose of this study was to refine Gravitational Insecurity (GI) assessment among Indian Children. GI assessment (original version) was examined with 28 children with GI and matched typically developing children. The results revealed that 9 items (Jumping, height jump, Stand on chair, jumping off chair with eyes closed, forward roll, backward roll, tilt board step, Supine ball-active and supine on ball – passive) were correctly discriminate GI children from typically developing children than the other six items (broad Jump, stick jump, Jump off chair with eyes open, prone on ball, swinging ball, bounced ball catch) . These 9 items were included in revised version of GI assessment. Revised version of GI assessment required 30-40 minutes for administration. It was time consuming to assess Gravitational Insecurity. May benson & Koomar suggested that GI assessment (revised version) has to be refined inorder to avoid time consuming.
This paper presents an enhanced 32-bit carry lookahead(CLA) adder implementing using the constant delay (CD) logic, targeting at full-custom high-speed applications. The CD characteristic of this logic style regardless of the logic type makes it suitable in implementing complicated logic expressions such as addition. CD logic exhibits a unique characteristic where the output is pre-evaluated before the inputs from the preceding stage is ready. This feature offers performance advantage over static and dynamic domino logic styles in a single-cycle multistage circuit block. Several design considerations including timing window width adjustment and clock distribution are discussed. Using 65-nm general-purpose CMOS technology, the proposed logic demonstrates an average speed up of 94% and 56% over static and dynamic domino logic, respectively, in five different logic gates. Simulation results of 8-bit ripple carry adders show that CD logic is 39% and 23% faster than
Development is explain not as an empirical term (Reese and Overton1970) and on occasion as through it is (Kaplan 1983) . Many times as what ever happens across the life span is what constitutes development. The concept of development centers on value based notion of improvement. In life span perspective the development is life long, interactive, multidimensional, culturally historically embedded process, shows plasticity, involves both gain and losses and has multidisciplinary field of study. (Sugarman 2001) The quality of life is interpreted differently as satisfaction (Summers 1976), happiness( Esterling 1978),psychological wellbeing( Andrews and Withey 1978) and degree of fulfillment of individuals important goals(Frish 1089) .In Positive Psychology the scientifically unwieldy notion of happiness is broken down several more quantifiable aspect: positive emotion (the pleasant life) engagement (engaged life) and purpose(meaningful life).

Background: One of the major concerns in intensive care units is caring. There was no universally accepted definition of the phenomenon, instead of decades of research in this field. Purpose: The study presented here was designed to explore the meaning of caring, particularly from the nurses working at a renowned intensive coronary care unit (ICCU). Method: Volunteers participated in semi-structured interviews and the interviews were recorded in a tape. The recordings were transcribed verbatim and the analysis was done using Colliazzi reductive framework. Findings: Being a nurse in the ICCU meant being valuable, professional, and confident. However, in some cases they were also frustrated. The theme that emerged from the meaning of caring include accountability, empathy, competency development and holistic service.
The purpose of this study was to determine the concentrations of toxic metals (Cd, Hg, Cr, Pb, As) in meat at the Kumasi Central Abattoir, Ghana by using a Varian 220 Atom Absorption Spectrophotometer. The levels of toxic metals in meat (cow, pig, sheep, goat, grass cutter, deer) varied in concentration. The concentration of lead was above the tolerance level in all the meat samples with the highest concentration recorded in beef at 1.154 mg/kg and the lowest at 0.037 mg/kg in pork. The amount of mercury, Hg observed in the various meat samples fell within the range of 0.059 mg/kg to 0.012 mg/kg, a little over the tolerable level of 0.05 mg/kg. The highest mercury, Hg concentration was observed in grasscutter meat (0.071 mg/kg) and the lowest concentration in pork, which was observed at 0.012 mg/kg, with the former above the permissible limit and
This paper presents Computational Fluid Dynamics (CFD) analysis of Pelton turbine of Khimti Hydropower in Nepal. The purpose of CFD analysis is to determine torque generated by the turbine and pressure distributions in bucket for further work on fatigue analysis. The CFD analysis is carried out on model size Pelton runner reduced at 1:3.5 scale to minimize computational cost and time. The operating conditions for model size runner is selected in accordance with IEC 60193 and IEC 1116. The paper describes the methods used for CFD analysis using ANSYS CFX software. 3 buckets are used to predict the flow behavior of complete Pelton turbine. k-ε and SST turbulence model with interphase transfer method as free surface and mixture model is compared in the paper. The pressure distribution is found maximum at bucket tip and runner Pitch Circle Diameter (PCD). The torque generated by the middle bucket is replicated over time to determine total torque generated by Pelton turbine.
