Leaves of roadside plants as bioindicator of traffic related lead pollution during different seasons in Sargodha, Pakistan

African Journal of Environmental Science and Technology , 2010,
Abstract: Plants are important bioindicators of heavy metal environmental pollution. For this purpose a study was conducted during winter and summer seasons in Sargodha, Pakistan. Three roadside plants that is Dalbergia sissoo Roxb., Prosopis juliflora L. and Eucalyptus spp. were collected from different locations. The study area was divided into five on the basis of traffic density and industrial pollution. These were Urban, Suburban, Industrial, Roadside and Rural. It was found that lead concentration was highest in the plants that were collected from industrial site in Dalbergia during winter and summer that is 421.43 ± 1 9.30 and 429.37 ± 14.49 ug g-1 respectively and lowest at the control site (rural site) 69.57 ± 36.80 ug g-1 in Eucalyptus during winter and 61.89 ± 35.97 ug g-1 in Prosopis during summer. All the three selected plants proved to be good indicators of lead pollution and due to their diverse distribution in different parts of the world their leaves can be used as bioindicators of lead pollution.

Jovian Problem: Performance of Some High-Order Numerical Integrators  [PDF]
Shafiq Ur Rehman
American Journal of Computational Mathematics (AJCM) , 2013, DOI: 10.4236/ajcm.2013.33028

N-body simulations of the Sun, the planets, and small celestial bodies are frequently used to model the evolution of the Solar System. Large numbers of numerical integrators for performing such simulations have been developed and used; see, for example, [1,2]. The primary objective of this paper is to analyse and compare the efficiency and the error growth for different numerical integrators. Throughout the paper, the error growth is examined in terms of the global errors in the positions and velocities, and the relative errors in the energy and angular momentum of the system. We performed numerical experiments for the different integrators applied to the Jovian problem over a long interval of duration, as long as one million years, with the local error tolerance ranging from 10-16 to 10-18.

Accuracy and Computational Cost of Interpolation Schemes While Performing N-Body Simulations  [PDF]
Shafiq Ur Rehman
American Journal of Computational Mathematics (AJCM) , 2014, DOI: 10.4236/ajcm.2014.45037
Abstract: The continuous approximations play a vital role in N-body simulations. We constructed three different types, namely, one-step (cubic and quintic Hermite), two-step, and three-step Hermite interpolation schemes. The continuous approximations obtained by Hermite interpolation schemes and interpolants for ODEX2 and ERKN integrators are discussed in this paper. The primary focus of this paper is to measure the accuracy and computational cost of different types of interpolation schemes for a variety of gravitational problems. The gravitational problems consist of Kepler’s two-body problem and the more realistic problem involving the Sun and four gas-giants—Jupiter, Saturn, Uranus, and Neptune. The numerical experiments are performed for the different integrators together with one-step, two-step, and three-step Hermite interpolation schemes, as well as the interpolants.

African Journal of Biotechnology , 2009,
Abstract: Cellulolytic enzymes have immense potential to convert cellulosic biomass into useful products. Tribolium castaneum crude proteins were isolated to screen the cellulolytic activities. The activity was established by substrate-agar plate assay and confirmed by endoglucanase assay. Cellulolytic activity was further purified and characterized using the different chromatographic techniques and electrophoresis. Gel filtration chromatography showed the presence of multiple forms of enzyme activities with different molecular weights. Stability of enzyme activity was investigated at different temperatures and pH. Optimum pH for was found 4.8 at 40oC determined as optimum temperature. Gradually decreasing Enzyme activity remained half at 60oC. Zymography and SDS-PAGE showed the presence of multiple forms of endoglucanase activities (Cel I and Cel II) with molecular weight of 55 kDa and 35 kDa.
Safety Management in a Manufacturing Company: Six Sigma Approach  [PDF]

Engineering (ENG) , 2012, DOI: 10.4236/eng.2012.47053
Abstract: The manufacturing company under consideration recorded the high accident rates for last few years. These accidents cause the organization the heavy man-day loss, the production loss and heavy costs of insurance. The objective of health and safety department at the manufacturing company was to set and improve accidents prevention system. The paper presents how does the six-sigma technique will help to evaluate the safety and environmental hazards in performance of organizations? It is observed that the study helped the management to measure, analyze and improve overall safety plan to protect the life and health of the employees.
Effect of cadmium on the growth of tomato
F. Rehman
Biology and Medicine , 2011,
Abstract: The present experiment was conducted to test the effect of cadmium (Cd) on the vegetative and reproductivegrowth of Lycopersicon esculentum cv. Navodaya (tomato). The selected plant species was treated 4 times with10, 20, 30 and 40 μg cadmium. The plant was treated twice at pre-flowering stage at 10 days interval and twice atpost-flowering stage. Almost all selected growth parameters were sensitive to all or at least high doses of Cd. Inthe present study, the total chlorophyll content increased in the plants treated with Cd. The plant biomassdecreased significantly on treatment with higher doses of Cd. The leaf number and leaf area was negativelycorrelated with the concentration of cadmium.
E-Marketing Practices: An Empirical Investigation of HSBC and Jammu & Kashmir Bank

Abstract: e-Marketing has a lot of benefits which add value to customers’ satisfaction in terms of better quality of service offerings the banks gain more competitive advantage over other competitors. The present empirical study focuses on identifying the key factors of e-marketing practices that have an adverse effect on the customers’ satisfaction. In this paper, two banks are taken under study i.e. HSBC (HongKong and Shanghai Banking Corporation) and J & K (Jammu & Kashmir Bank). In this paper respondents are selected through Random sampling; while the survey Instrument was a developed Questionnaire comprising questions based on Likert scale. The Likert scale has a 5 point scale (indicating 1 = Strongly Disagree, 2 = Disagree, 3 = Neutral , 4 = Agree and 5 = Strongly Agree) divided into two (2) sections: personal details and customers’ opinion towards e-marketing through the medium of Internet banking, mobile banking and ATM (Automated Teller Machine). The instrument contained 12 items and was administered to about 200 respondents, while 157 completed and returned their Questionnaire. The statistical techniques used for the analysis were Independent sample Test. The Independent sample test revealed that the customer satisfaction of e–marketing practice offered by HSBC and J & K banks have significant influence on their customers at 95%. In this study the main focus is on the e-marketing practices which are prevailing in both the banks that is Internet Banking, Mobile Banking and ATM (Automated Teller Machine). Results of independent sample t-test shows that Internet Banking, Mobile Banking and ATM practices were most important factors in customer satisfaction in both the banks.

Thecommonest ABO +ve group was O +ve present in 40.03% (CL 37.48% - 42.69%) followed by B +ve in 30.31% (CL27.95% - 32.78%), A +ve in 18.21% (CL 16.27% - 20.34%) and AB +ve in 1.8% (CL 1.21% - 2.66%) donors. The mostcommon ABO -ve was O -ve present in 4.54% (CL 3.56% - 5.77%), A -ve in 2.66% (CL 1.93% - 3.66%), B -ve in 2.23%(CL 1.57% - 3.17%) donors. Conclusion: Blood group O is the commonest ABO blood group and 90.35% are RH +vein this area.
