Successful project management depends upon practicing nine knowledge areas; managing project scope, time, cost, quality, time and workload management for human resources, stakeholder communication, procurement, risk and integration of all these. However, existing literature does not give primary importance to workload management for human resources. From July 2007 to April 2009, this study observes that in the IT industry working in Islamabad, Pakistan, workload management was considered as support or secondary function of human resource management. Focusing on workload management this study hypothesized that the quality of the workload management determines the project outcome. Adopting stratified sampling 70 heterogeneous IT projects from 24 different software houses were selected. Using a reliable instrument, data was about the quality of workload management by the project managers and the consequent results of the IT projects was collected in a cross sectional manner. The data was analyzed using frequency distribution, Pearson correlation and linear regression. The findings confirmed a strong correlation and dependency of project outcome on proper workload management. This study recommends good quality workload management a primary tool for determining the project’s scope, time and cost. The study contributes guidelines and templates to help project managers improve workload management skills and its role in project outcomes respectively.

A micro strip-fed monopole antenna for ultra-wideband antenna with triple band notched and WLAN antenna is presented and analyzed in detail. In the UWB antenna three different frequencies are notched by means of using E-shaped resonator. The three notched frequencies are 3.6 GHz (WLAN), 5GHz (WLAN) and 10 GHz (X- band) with a reference level of s11 > -10dB. The center frequency of the notched band is 7 GHz. The frequency band of the proposed antenna is 0 GHz-11GHz for voltage standing wave ratio (VSWR) less than 2.Surface current distributions and transmission line models are used to analyze the effect of these slots. The antenna is successfully fabricated and measured, showing broad band matched impedance and good Omni directional radiation pattern. The designed antenna patch has a compact size of 17x13.8 mm2.

This paper proposes a novel approach for optimal allocation of a distributed generator in a radial distribution feeder for tail end node voltage improvement and loss minimization during peak load. A multi objective optimization method is proposed to determine optimal allocation of a distributed generation (DG) unit in a radial distribution feeder. The DG allocation problem has been formulated as multi objective function which includes two objectives: viz Power Loss Reduction and Tail End Node Voltage Improvement with associated weights. The proposed methodology uses Genetic Algorithm to optimize the multi objective function. This method is tested on standard IEEE 33 bus and 69 bus radial distribution systems using MATLAB 8.0. The results show that the proposed method yields considerable tail end node voltage improvement along with significant reduction in line losses during peak load.

WHO defines Overweight and obesity as abnormal or excessive fat accumulation that presents a risk to health. A crude population measure of obesity is the body mass index (BMI), a person’s weight (in kilograms) divided by the square of his or her height (in metres). A person with a BMI of 30 or more is generally considered obese. A person with a BMI equal to or more than 25 is considered overweight.

The unsteady state mass conservation equation for chlorine concentration decay in drinking water in a pipe line network for axisymmetric flow is solved analytically with the help of Hankel transform. The numerical values and graphical representations are shown by using MATLAB for various values of chlorine consumption rate, diffusivity, time and fluid velocity etc.

The evaluation of I0 (?) and Q0 (?) for Gold, Cupper, Thorium, Uranium and Potassium in Modified Irradiation Site of Nigeria Nuclear Reactor-1 (NIRR-1) was done using Instrumental Neutron Activation Analysis (INAA) and off-line gamma ray spectrometric technique. It was found that before the Cd-lined installation i.e. modification of the large irradiation site (A-3) of NIRR-1, the deviation parameter (?) was positive with a value of 0.024±0.002 indicating high neutron thermalization. However, after the Cd-line installation, the ?-parameter was found to be negative with a value of -0.9274 ± 0.016 indicating poor thermalization and as a consequence achieved the purposed of the modification. Further correction for Q0 to Q0 (?) and I0 to I0 (?) for the nuclides; Au, Cu, Th, U, and K in the modified large outer irradiation channel A-3 were done. Before Cd-lined installation the Q0 (?) values for Au was 15.05, for Cu was 0.88, for Th was 10.05, for U was 0.86 and for K was 90.37. However, after the Cd installation the Q0 (?) values for Au increased to 139.64, for Cu increased to 4681.32, for Th increased to16661.89, for U increased to 6141.55 and for K it increased to 133177.92. Also, before Cd-lined installation (BF), I0 (?) values for Au and Cu were 1485.410, 3.870 and after Cd-lined installation they increased to 13782.47 and 18631.64 respectively.

The study finds the relationship between abnormal lower discretionary expenses and future financial performance. Four measures of financial performance measures; Return on Asset (ROA), Return on Equity (ROE) and Earning per Share (EPS) and Price to Earnings ratio (PE) are taken. Manufacturing firms listed on Karachi Stock Exchange (KSE) are selected for analysis and data is collected from year 2004 to 2011. Financial data is collected from the annual reports of the firms and data of market value is collected from business recorder site. Panel data analysis technique, Generalised least square methods is used for analysis. It has been revealed that there is negative impact on firm’s subsequent performance which reduced discretionary expenses to report higher earnings but this impact is not significant.
