The present study was planned to study the influence of Rimonabant pretreatment (1 week) on the anti-diabetic activity of oral anti-diabetic agents in albino & Streptozotocin induced diabetic rats. Rimonabant (0.36mg/kg) & Sulfonylureas like Glibenclamide (180µg/kg) and Glipizide (270µg/kg) were administered and the time to onset of hypoglycemia, duration of the hypoglycemia & peak hypoglycemia were determined. Then Rimonabant (0.36mg/kg) was administered for 1week and on the next day 1 hour after Rimonabant treatment, the hypoglycemic effect of Sulfonylureas were evaluated. The results showed that co- administration of Rimonabant with Glipizide and Glibenclamide had positive influence on the peak hypoglycemic effect and a significant enhancement in the duration of hypoglycemic action in both normal and diabetic rats. This increased hypoglycemic activity of Glipizide and Glibenclamide after Rimonabant treatment may be due to improved insulin sensitivity and other insulin-resistant state in diabetes.

Stress has been viewed as an inevitable consequence of work life. A worker will fell stress when his or her does not match their job requirements. Work stress come from a variety of sources and it can affect people in different ways. In the report The Scale of Occupational Stress (Smith et al., 2000 in Jeremy, 2005) it was estimated that there were 5 million workers suffering the high level of stress at work. The study shows the important outcomes that approximately one in five workers reported stress arising from work. There were cause by excessive workloads or lack of managerial support, ill health and back pain, together with certain health related activities such as smoking and alcohol intake.

The potential of Mobola Plum seed to serve as raw material for industrial applications, domestic consumption was examined by this study. The moisture content, crude protein, crude fat, crude fibre, ash and carbohydrate were 5.11 %, 33.10 %, 5.15 %, 1.60 %, 2.65 % and 52.39 % respectively. The seed is a veritable source for Carbohydrate and protein, which enhance its potential usage for food and feed formulation. The fatty acids profile of the oil showed that it contains high level of unsaturated fatty acids. The Mobola Plum seed oil could be a good source of edible oil for human consumption.

In present investigation mycoflora from groundnut, soybean, sesame, safflower and sunflower was isolated by using different agar media. Total thirty fungi were isolated from these oilseeds and screened against different plant leaf extract and latex. It was found that, out of five oilseeds, soybean yielded ninteen fungi, fifteen fungi were found to be associated with sesame and safflower seed. On the other hand sunflower yielded only nine fungi. Aqueous extract of Eucalyptus angophoroides retarded the growth of Alternaria dianthicola, Curvularia pellescens, Fusarium oxysporum, Macrophomina phaseolina, Rhizopus stolonifer, Penicillium digitatum and Penicillium chrysogenum. The latex of Calotropis gigantia for Alternaria dianticola; Aloe vera for Curvularia lunata and Penicillium digitatum were found to be fungitoxic.

In this paper we prove that the graphs obtained by duplication of an edge in , mutual duplication of pair of edges and mutual duplication of pair of vertices between two copies of cycle admit product cordial labeling. Moreover let and be two graphs such that their order and/or size differ by at most 1 then we prove that the new graph obtained by joining and by a path of arbitrary length is a product cordial graph.

This paper investigates a two multi-component unit parallel system model with imperfect detection and common cause failure. A single repair facility is always available with the system but whenever a regular detector fails in detection of the failure cause, then the unit goes for replacement for which a single replacement facility is always available. Using regenerative point technique various measure of system effectiveness are obtained. The behaviour of MTSF and profit function have been studied in a particular case.

Effect of chemical reaction on free convection MHD flow through a porous medium bounded by vertical surface is studied here. The governing equations involved in the present analysis are solved by the two-term perturbation method. The velocity, temperature, concentration, skin friction and Nusselt number are studied for different parameters like thermal Grash of number, mass Grash of number, Schmidt number, magnetic field parameter, Permeability parameter, Prandtl number, Eckert number and chemical reaction parameter.

The study is examined how employee’s job performance is affected by job involvement and reward system. The main objective of this study is examined how job performance of the employees is affected through described independent variables that are job involvement and reward system in banking sectors. This study examined that Effective Reward system and job involvement of employees playing important role in every organization since from many years and organization itself pays more attention to these kinds of sensitive matters because organization knows these 2 matters can increase their overall profit or increase organizational productivity. This study shows Reward system refers to that program which is offered by any organization for the purpose to increase employee performance and employee productivity.

The purpose of this study was to determine the levels of trace elements in some selected fruit juices and carbonated beverages purchased in Accra metropolis, Ghana. The technique used in this study was Instrumental neutron activation analysis (INAA). Fruit juices considered in this study includes pineapple, strawberry, lemon and orange. Some carbonated drinks were also analysed in this analysis. The trace elements considered were Al, Br, Ca, Cl, Mg, Mn, Na, K, Cd, Co, and As. Generally, the trace elements in the fruit juices were found to be more than that of the carbonated beverages. As, Cd, Co and Br were not detected in any of the samples analysed. Also Ca, Mg, Mn were not present in all the carbonated drinks studied. The levels of trace elements in both the fruit juices and carbonated drinks were however within permissible levels.

The Study examined gender-based labour contribution and decision making role among maize farming households in Lafia Local Government Area, North-central Nigeria. Data were collected using structured questionnaire from 60 households randomly selected and analyzed with descriptive statistics and decision making index (DMI). The results showed that Male members of maize farming households contributed 74% of the total household labour needed for maize production per hectare in the study area. However, labour contribution towards post-harvest farm operations by female farmers was 16% higher than that of male. Male farmers in maize farming households dominated decision making role for all activities (with DMI? l) except for processing (1.6) and consumption (1.6) of farm produce decision activities. Poor income, culturally gender-assigned responsibility, poor access to farm inputs, multiple domestic responsibility were ranked major constraints to women contribution to household farming decisions. In order to encourage greater participation of women in agricultural production and household farming decisions for increased food production and income, efforts should be made towards improving women access to farm inputs and credit facility. Literacy and sensitization progamme on gender issues should be embark upon for the purpose of promoting shared responsibilities.
