Abstract: Nitrogen availability can be enhanced with the application of nitrogen fixing bacteria and it may be helpful in increasing forage yield and improving quality of oat. Therefore, a field trial to evaluate the effect of seed inoculation with nitrogen fixing bacteria on forage yield and quality of oat was carried out at Agronomic Research Area, University of Agriculture, Faisalabad during Rabi season 2013-14. The experiment was laid out in Randomized Complete Block Design (RCBD) with factorial arrangements using three replications. The experiment was comprised of two integrated approaches. The first approach was oat cultivars consisting of four treatments, V1 (AVON), V2 (S-2000), V3 (S-2011) and V4 (PD2LV65) and the second approach was seed inoculation consisting of three treatments, S0 (control), S1 (Azotobacter spp.), S2 (Azospirillum spp.). Fisher’s analysis of variance technique was used for statistically interpretation of data by using least significant difference (LSD) test at 5% level of probability. Nitrogen fixing bacteria significantly affect the germination count (m2), plant height (cm), number of tillers (m2), number of leaves per tiller, leaf area per tiller (cm2), green forage yield (t·ha-1) and dry matter yield (t ha-1). The maximum green forage yield (85.2 t·ha-1), dry matter yield (14.1 t ·ha-1) and crude protein (11.5%) were recorded where Azotobacter inoculation was applied. The interaction between cultivars and nitrogenous strains was significant for green forage yield (t·ha-1), dry matter yield (t·ha-1) and crude protein (%). Conclusion showed that cultivar Sargodha-2011 which was inoculated with Azotobacter spp. gave higher forage yield of good quality.

Abstract: In order to study the response of "Various Wheat cultivars to different levels of salinity at early growth stage" a pot experiment was conducted in the green house of NWFP, Agricultural University Peshawar, Pakistan during 1990. Statistical analysis of the data revealed that various salinity levels, cultivars and their interaction had a significant (p=0.05) effect on germination, emergence, plant height, root length, fresh shoot weight, and fresh root weight. It was clear from the result that addition of salt progressively reduced germination, plant height, root length, fresh shoot weight, and fresh root weight and cumulative reduction for the parameters were maximum at salinity level of 30 dSm-1 when compared with other treatments. Wheat cultivar, mutant and LU 26s proved more salt tolerant than the other cultivars with respect to the parameters under study.
Jovian Problem: Performance of Some High-Order Numerical Integrators  [PDF]

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]

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.

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

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.

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.
