Ahmed Waqas,Muhammad Zubair,Hamzah Ghulam,Muhammad Wajih Ullah,Muhammad Zubair Tariq Majeed
PeerJ , 2015, DOI: 10.7287/peerj.preprints.523v1
Abstract: Background: The objectives of the study were to explore the knowledge and attitudes of Pakistani university students toward mental illnesses. People with mental illnesses are challenged not only by their symptoms but also by the prejudices associated with their illness. Acknowledging the stigma of mental illness should be the first essential step toward devising an appropriate treatment plan. Methods: A cross-sectional survey was conducted at the University of Punjab, Lahore, CMH Lahore Medical and Dental College, Lahore, and University of Sargodha, Sub-campus Lahore, from February to May, 2014. The self-administered questionnaire consisted of three sections: demographics, general knowledge of psychiatric illnesses, and Community Attitudes towards Mental Illnesses (CAMI) Scale. The questionnaire was distributed to 650 participants enrolled in different disciplines (Social Sciences, Medicine and Formal Sciences). Results: Response rate was 81% (527/650 respondents). Mean age was 20.98 years. Most of the students (331, 62.8%) had an urban background and studied Social Sciences (238, 45.2%). 418 (79.3%) considered religion very important and most respondents considered psychiatrists (334, 63.4%) and spiritual leaders (72, 13.7%) to be best able to treat mental illnesses. 169 (32.1%) considered black magic to be a cause of mental illness. Only 215 (41%) had ever read an article on mental illnesses. Multiple regression analysis revealed study discipline, exposure, perceived causes of mental illnesses and superstitions to be significantly associated with attitudes towards mental illnesses (p < .05). Conclusion: Although low awareness and exposure were found in this sample of Pakistani university students, their attitude towards mental illnesses was generally positive. Most respondents gave supernatural explanations for mental illnesses but only a few believed that spiritual leaders can play a role in treatment.

Rehmat Ullah, Muhammad Zafarullah Khan, Kalim Ullah, Tahir Munir Butt
Agricultural Sciences (AS) , 2015, DOI: 10.4236/as.2015.69092
Abstract: The instant study was conducted to estimate the Model Farm Services Center’s (MFSC) contribution in yield improvement of major crops/vegetables in district Dera Ismail Khan, Khyber Pakhtunkhwa, Pakistan, during the year 2014-15. Based on Sekaran sampling technique 306 respondents were selected and were personally interviewed through well prepared and pre-tested interview schedule. To find out the actual performance of yield improvement by Model Farm Services Center along with other repressors, step by step analysis was performed. The results of Wilcoxon Sign Rank Test showed significant improvement in yield of sugarcane, wheat, maize, rice and tomato by Model Farm Services Center. Pearson’s correlation coefficient showed highly significant positive relation of sugarcane and wheat yield difference before and after Model Farm Services Center registration with MFSC. Ordinary Least Square Multiple-Regression Model indicates that MFSC registration duration and landholding significantly define the variation in dependent variables at 1% and 5% level of significance respectively for sugarcane yield. Whereas solely Model Farm Services Center registration duration profoundly highly significantly (P ≤ 0.01) explains the variation in dependent variables in wheat yield.
Correlation and Causality between Inflation and Selected Macroeconomic Variables: Empirical Evidence from Pakistan (1990-2012)  [PDF]
Mehwish Nawaz, Muhammad Naeem, Sami Ullah, Salim Ullah Khan
iBusiness (IB) , 2017, DOI: 10.4236/ib.2017.94011
Abstract:

Inflation is regarded as one of the most chronic problems in Pakistan and the recent surge of inflation (10.8) in consumer price index is a matter of serious concern in the economy [1]. Inflation imposes high cost on economies and societies; disproportionately hurts the poor and fixed income groups, creates uncertainty throughout the economy and undermines macroeconomic stability. It also results in inefficient resource allocation and hence reduces potential economic growth. High inflation has always penalized the poor. Lowering inflation therefore, directly benefits the low and fixed income groups. The present study focuses to examine the impact of various macroeconomic variables on inflation in Pakistan and to find their correlation and causal relationship with economic and econometric criterion by using time series data over the period of 1990 to 2012. To achieve this objective, regression analysis, correlation coefficient and granger causality test are used. Results from regression analysis indicate that money supply, government expenditure, government revenue, foreign direct investment and gross domestic product have positive impact on inflation in Pakistan, while interest rate shows negative impact. Correlation analysis confirms that there exists a positive association of inflation with money supply, government revenue, interest rate, foreign direct investment, gross

Shahbaz Awan, Muhammad Ali, Muhammad Asif, Amjad Ullah
Energy and Power Engineering (EPE) , 2012, DOI: 10.4236/epe.2012.44028
Abstract: Pakistan is facing acute energy crises since last few years. Due to shortage of fuel oil and its sky touching prices, it seems very uneconomical to generate electricity from fuel oil. In order to generate cheap electricity we have to rely on renewable energy resources. To address these challenges, wind power generation is among the popular options in the world which is now being considered in Pakistan as well. However unremitting change in wind speed from calm to stormy introduces real challenges. Storing wind energy in batteries during the periods of low demand seems an expensive option, especially when dealing with large scale power generation. Due to incessantly varying nature of wind speed, it is not feasible to rely only on wind power for cheap power production. Also, it is not thriftily possible to construct separate transmission line. However if we integrate wind power with hydro power, we can utilize the maximum possible transmission capacity. Existing hydro power station operating in that area or pumped storage scheme can be used. This paper is an attempt to analyze coordination of wind generation with hydro power in those areas of Pakistan where both wind and hydro power sources exist. In this paper, different issues have been analyzed taking case study of Dargai. This paper is first attempt in Pakistan about integration of wind and hydro power to draw some general conclusions and to point out some areas in which further research can be done.

Engineering (ENG) , 2019, DOI: 10.4236/eng.2019.111003
Abstract: Aerodynamics analysis has become a mindset for high performance vehicles. This is because it provides valuable insight on a vehicle motion during different phases. There are vast varieties of software available like ANSYS Workbench, Star CCM+, Autodesk Simulation, SimFlow, FeatFlow, Autodesk Inventor etc. Amongst these softwares, Star CCM+ and ANSYS Workbench are the most widely used. Normally, it is observed that considerable users are confused in choosing the right software for CFD simulation because of a large variety of commercially available softwares. The present study provides comparative results to users of Computational Fluid Dynamics (CFD) with the driven case study. In the present case, authors chose the most commonly used CFD softwares, the ANSYS Workbench Fluent and the Star CCM+. Polyhedral meshing was applied on computer aided model of a car in both of these softwares. It has been found that coefficients of drag and lift achieved by aerodynamic analysis of a car are in a small marginal approximation between both ANSYS Workbench Fluent and Star CCM+ softwares. In the case of Star CCM+, CD was around 0.261 and CL was 0.07; however, in the case of ANSYS Workbench Fluent approximations were found to be 0.271 for CD and 0.05 for CL.

Abstract: Bank credit plays an important role in the economy of any nation. The current study examined the association among bank credit to private sector and economic growth in Pakistan. Economic growth was taken as dependent variable, while bank credit to private sector, interest rate, inflation, investment to GDP and government consumptions were taken as independent variables. Secondary data were collected from World Bank Indicator, ranging for the period 1973 to 2013. Descriptive research and correlation were used to check the normality of data. Unit root test was used to check the stationarity of variables. Co-integration VECUM and Granger Casuality test were statistically used to test the variable relationship and casuality effect of the variable. Regression analysis was used to analyze the impact of bank credit on economic growth. The findings of the study showed that bank credit had extensive relationship with economic progression; in short term the relationship was also significant. Regression analysis showed that there was adverse impact of bank credit on economic growth in Pakistan. However, problem associated with bank credit facility is the constraint and regulation imposed by SBP on the percentage of credit to be given to the Entrepreneurs. For solitary in the meantime bank lending has a casual influence on economic growth, there is a policy need to give devotion to liberalization the monetary sector.
