The present paper is focused on the modification of the properties of polystyrene by adding cobalt chloride and manganese chloride. The composites are prepared using casting technique with different percentages of fillers. The experimental results show that the D.C conductivity of composites increases with the increase of cobalt chloride and manganese chloride concentrations. The D.C electrical conductivity changes with increasing of temperature. Also the activation energy of electrical conductivity of (PS-CoCl2) and (PS-MnCl2) composites decreases with increasing cobalt chloride and manganese chloride concentrations.

Voltage instability is the major concern of power system stability. It is caused due to the deficit of reactive power in the system. Improving the systems voltage by increasing the reactive power handling capacity of the system by using Static VAR Compensator, during a large disturbance is the area of study. The simulations are carried out for IEEE 14 bus system by using MATLAB/PSAT software. The result shows the effectiveness of SVC to improve the voltages when connected to a system.

In this work we have demonstrated an experimental study and theoretical analysis of the effect of power intensity of illumination on the SnO2/n-Si Hetero-junction devices that irradiated with 150 min. (Cs 137) Gamma ray. The (J-V) characteristic was plotted as function of power intensity of illumination (1.95, 2.88, 3.78, 5.9, and 9.5) mw/cm2. This was shown increase in efficiency of this device until reach maximum efficiency at 9.5 mw/cm2 which represent optimal case. Theoretical analysis of this processes achieve by using “Table Curve 2D version 5.01” program leading to estimate theoretical modeling equation Y= a + b x +c ex We calculate these parameters (a, b, and c) as function of power intensity and testing the equation for power intensity (4 and 8 mw/cm2). Theoretical (J- V) curves are plotted with experimental data, there is a good agreement between them and the behavior of these two curves contain linear term and exponential term.

Non-traditional method (grinding) was used for the preparation of novel schiff bases from 4-amino-3-methyl phenol / 2-amino-4-methyl phenol and several aldehydes and ketones under catalytically free condition. This procedure constitutes an energy efficient, shorter time, higher yield as well as green synthesis approach. Some synthesized products were characterized by IR, NMR and MASS and also tested for antibacterial (Escherichia coli, Staphylococcus aureus, Bacillus subtilis, and Klebsiella pneumonae) activities by disc diffusion method

Current perspectives on the early childhood curriculum stress the need for a play-based program for children. Although the status of play has been given due to emphasis in the Malaysian Preschool National Curriculum, the implementation of play in the daily practice may not be consistent with the curriculum guidelines. Therefore, this study set out to examine the preschool teachers’ perception on the implementation of play in the private preschools. This study adopts the survey method, involving 105 teachers from 35 private preschools in Tampoi and Skudai, Johor. The questionnaire comprised of 46 items modified based on the CIPP model with the focus on the Input and Process constructs. Data were analyzed using descriptive analysis (mean, rank and standard deviation). Results on input evaluation revealed that although the teachers viewed play positively, they perceived possessing only average pedagogical knowledge about the implementation of play. On the other hand, the respondents believed that parents’ attitude towards the play concept was averagely positive. The overall appropriateness and availability of resources were also rated average. As for the process evaluation, the aspects of play management and the observation of the children’s behaviors were claimed to be average. A few suggestions were highlighted in the end of the study to enhance the effectiveness of the implementation of play in preschool curriculum.

Thyroid hormones has profound effects of lipid metabolism and carbohydrate homeostasis . Abnormalities in serum lipids and lipoproteins are frequent findings in thyroid dysfunction, mainly in hypothyroidism. Impaired glucose tolerance and insulin resistance have been documented in patients with thyroid dysfunction. In addition, thyroid hormones are remarkable regulators of energy metabolism, being the adipose tissue the largest fuel storage compartment. Furthermore, thyroid hormones share some physiological actions with adiponectin, such as reduction of body fat by increasing thermogenesis and lipid oxidation .However, a few number of studies have found low adiponectin levels in hypothyroid subjects (Díez and Iglesias, 2009). Cortisol excess in man is characterized by abdominal obesity, hypertension, glucose intolerance or diabetes and dyslipidemia. All these features share a state of insulin resistance, and contribute to high cardiovascular risk typical of this condition. Glucocorticoids negatively regulate adiponectin mRNA in human visceral adipose tissue. Cortisol counteracts the action of insulin at multiple sites, and increases hepatic gluconeogenetic efficiency (Fallo et al.,2004). Study the relationship between adiponectin with thyroid hormones and cortisol for both gender and for both control and diabetic groups also in diabetic patients according to duration of disease. This study was conducted between November 2010- November 2012 and, it was carried out at the diabetic Centre / Merjan Teaching Hospital in Babel Province by taking 120 diabetic patients(Type II DM) (60 male and 60 female) with disease duration (0-5),(>5-10 )and (>10 )years ,with age average (30-65 year)and most of them were on oral hypoglycemic drugs. While the study included 40 people apparently healthy that included 20 male and 20 female with age average (30-65 year).

In multivariate sampling, the major interest is on the problem of estimation of several population characteristics which often make conflicting demands on the sampling procedure. In this type of survey, the best allocation for one item may not in general be the best for another. There is the need to come up with compromise solution in a survey with many characteristics under study. This paper focuses on comparing some techniques of optimum sample allocation which are Yates/Chatterjee, Booth and Sedransk and Vector Maximum Criterion (VMC) on five sets of real life data stratified into six strata and two variates with desired variances using: (i.) Method of maximum variances with fixed n and (ii.) arbitrary fixing of variances. The stratum sample size nh among the classes are obtained to ascertain the criterion that will produce the smallest n. Based on the set of data collected and used for the empirical study it was discovered that Vector Maximum Criterion (VMC), Booth and Sedransk are superior to Yates/Chatterjee.

The search for more effective hypoglycaemic agents continues to be an area of research interest. World Health Organization recommended the use of alternative therapy especially in countries including, Nigeria, where access to conventional treatments of diabetes is inadequate. Majority of people in Abeokuta were majorly peasant farmers and petty traders who could not afford high cost of pharmaceutical remedies of diabetes which is very rampant as a result of poor feeding pattern. However, naturally endowed plants such as Hibiscus sabdariffa are found everywhere, parts of which are taken as vegetables without putting into consideration its hypoglycemic advantages. However, this study could assist in providing some information needed for the health improvement of the rural populace (Abeokuta) as regards diabetes. Combination of 300g M. lucida + 100g A.sativum+l00g Z. officinale produced the best hypoglycaemic effect (69.85%) in alloxan-induced diabetic rats.

Background: The parity is the number of times that she has given birth to a fetus with a gestational age of (24) weeks or more, regardless of whether the child was born alive or was stillborn. The aim of this study is to shed more like on the role of effect parity on fibrinogen level. Objectives: study the effect of parity on the plasma fibrinogen in normal pregnant Sudanese women, and determination of levels of plasma fibrinogen in pregnant women Material and method: cross- sectional study was conducted at Algazera& Khartoum states during October to November 2015. (120) normal pregnant women with age ranging (20 – 42) years, classified as (60) non pregnant women (nullparas) as control group, (30) multiparae and (30) grand multipara’s. Results: The concentration of fibrinogen in the multiparae mean (6.20) as compared to (8.52) mg/dl in the control group (P.value 0.266) was insignificant, Grand multipara mean (3.77) as compared to (8.52) mg/dl in the control group (P.value 0.015) were significantly decreased compared to control.Conclusion: Normal pregnant multipara and grand multipara women fibrinogen levels are lower than in aged matched with non pregnant women. These changes are not directly associated with lipid metabolism during pregnancy (8).

This paper explored the motivations for beneficiaries’ participation in community-based agriculture and rural development program among Guba farmers in Nigeria. Utilizing qualitative research approach, the data for the study was collected through in-depth interviews and focus group discussion based on semi-structured questions from 8 key informants. The data collected was analyzed through open-coding system. Findings of the study indicates that though, several reasons have been identified by informants as their motivations to participate in the program, the desire by beneficiaries to meet tangible material benefits stood above all other considerations. However, Group leadership, Workshops and Seminars, the program’s approach, Officials / beneficiaries’ relationship and publicity given to the program were also found to have motivated beneficiaries’ participation. At the end, the paper made recommendations to practitioners and policy makers in designing future developmental programs that ensures popular participation. This will in the long run ensure the sustainability of the programs and effective poverty alleviation.
