    The assessment of groundwater is essential for the estimation of suitability of water for safe use. An attempt has been made to study the groundwater of selected areas of Punjab (Sheikhupura & Sahiwal) and Sindh (Sindh, Jawar Dharki and Dharki), Pakistan. The results indicate that pH, color and odor were all within limits of WHO that is pH ranges 6.5–8.5, colorless and odorless respectively. The high values of suspended solids were observed in the Sindh-1 and Dharki samples. Microbiologically only Sahiwal and Jawar Dharki were found fit for drinking purpose. Trace metals analysis of Sheikhupura-1 and Sindh-1 has showed that they do not fall within limits of WHO for Iron. The ionic concentration analysis showed that high bicarbonate (HCO3-), ions are present in the samples of Sahiwal and Dharki; Sindh-1 and Jawar Dharki samples have showed very high concentration for chloride ions, all samples were satisfactory level for sulphate (SO42-), sodium, magnesium and phosphate ions except samples of Sindh-1 and Jawar Dharki. High concentration of calcium and potassium ions noticed in samples of Sindh-1 while all samples were found fit for drinking purposes in respect of nitrate, nitrite and ammonium ions. The high concentration of Fluoride was found only in Sheikhupura-2 samples

    Glucuronoxylan hydrogel (GXH) isolated from M. pudica seeds was assessed for acute toxicology in albino mice that were alienated into four groups. Three groups, i.e., II, III and IV received GXH at a dose of 1, 2 and 5 g/kg, respectively while group I was retained untreated and provided routine diet. After administering GXH, mice were examined for vomiting, diarrhea, allergy and tremors for 8 h. All animals were carefully observed for food and water consumption at 1, 2, 3, 7 and 14 day after administering GXH. At the end of studies, blood samples were drawn for investigation of hematological and biochemical parameters. All animals were sacrificed, relative body weight of vital organs was calculated and their histopathology was studied. It was concluded that there was insignificant difference in body weight, behavioral pattern, food and water intake among treated and control groups. Haematology and biochemistry of blood samples from all groups were found analogous. Histopathological evaluation of vital body organs exhibited no lesions in all groups. Ocular, cardiac and dermal safety of GXH was also established on albino rabbits

    Human Resource Outsourcing has become one of the familiar thoughts to the media and business terms. This research is focused on the predictor and consequences of human resource outsourcing in educational institutions. Further, it helped us to establish a framework which would clearly highlight the factors and consequences of human resource outsourcing in educational institution of Baluchistan “Quetta”, Pakistan along with advantages and disadvantages of Human resource outsourcing policies. The Baluchistan was taken for research because this province has very less literacy rate. The research comprises very latest empirical and theoretical work which directly addresses the predictors and consequences of Human Resource outsourcing. Human resource outsourcing positively increases these effects in higher educational institutions. The study found that human resource outsourcing has negative effect on time management and communication issues in higher educational Institutions thus it can be said because of human resource outsourcing organizations may feel time management conflicts and communication issues among their employees. The results of 2 sample t test concluded that human resource outsourcing level does not differ in public and private institutes of Quetta, Baluchistan

    Purpose: To examine the ethnomedicinal claims regarding the antidiabetic uses of Cassia sophera L. (Caesalpiniaceae) using an alloxan-induced diabetes model.Methods: The methanol extracts of leaves (CSLM) and roots (CSRM) of C. sophera were evaluated for hypoglycemic and anti-diabetic activities in normal and alloxan-induced diabetic rats. Alloxan (120 mg/kg, i.p.) was administered to induce diabetes in rats. A dose regime of 50, 100 and 200 mg/kg of CSLM and CSRM was given orally to the respective groups (n = 6). Blank group consisted of normal animals maintained on saline. The diabetic untreated group served as negative control while the group that received glibenclamide (5 mg/kg) was positive control.Results: A significant (p < 0.05) lowering of fasting blood glucose level FBG in oral glucose tolerance test (OGTT) in normal rats was observed after daily  administration of the extract for 7 days. Both extracts demonstrated decreased (p < 0.05) BGL with significantly (p < 0.05) improved glucose tolerance and body weight at the end of 4th, 7th and 14th day in extract-treated diabetic rats when compared with negative control and normal untreated group, respectively. In normoglycemic rats, CSLM and CSRM showed dose-dependent decrease in BGL.Conclusion: These results suggest that both extracts possess significant blood glucose lowering activity in normal as well as in diabetic rats.Keywords: Cassia sophera, Hypoglycemic activity, Anti-diabetic activity, Alloxan, Weight los

    Analysis and Forecast of Mining Fatalities in Cherat Coal Field, Pakistan

    Get PDF
    Mineral exploitation contributes to the economic growth of developing countries. Managing mineral production brought a more disturbing environment linked to workers' causalities due to scarcities in the safety management system. One of the barriers to attaining an adequate safety management system is the unavailability of future information relating to accidents causing fatalities. Policymakers always try to manage the safety system after each accident. Therefore, a precise forecast of the number of workers fatalities can provide significant observation to strengthen the safety management system. This study involves forecasting the number of mining workers fatalities in Cherat coal mines by using Auto-Regressive Integrating Moving Average Method (ARIMA) model. Workers' fatalities information was collected over the period of 1994 to 2018 from Mine Workers Federation, Inspectorate of Mines and Minerals and company records to evaluate the long-term forecast. Various diagnostic tests were used to obtain an optimistic model. The results show that ARIMA (0, 1, 2) was the most appropriate model for workers fatalities. Based on this model, casualties from 2019 to 2025 have been forecasted. The results suggest that policymakers should take systematic consideration by evaluating possible risks associated with an increased number of fatalities and develop a safe and effective working platform
