Since the emergence of software engineering the perfect requirements have a deeper effect on the overaU quality of software systems. This research paper is focusing on the shortcomings or limitations of existing software requirements prioritization techniques and paves the way for researchers to explore new horizons in software requirements prioritization. Most of the techniques are solving the plight of smaU projects or toy applications. There is not a single evidence of a successful prioritization technique that would solve the problem of large set of requirements. The innovative requirements prioritization approaches are required for systems where user requirements increase in hundreds and even in thousands. The existing techniques are not providing sufficient automation for such systems due to their certain limitations.

It is a stare of over-nutrition with long-term complications such as dyslipidemia, hypertension, and coronary artery disease and type-2 diabetes. Underweight is the result of under nutrition leading to reduction in growth and development of every body organ especially the Central Nervous System. Long-term under-nutrition causes failure in linear growth (height) of the child. Growth is further retarded by the repeated attacks of respiratory infections, diarrhea and anemia as a result of reduced immunity. This study was carried, out eight primary schools of Dera Ismail Khan (Private, semi government organizations, and welfare foundations) having mixed population with some of the wards belonging to high socioeconomic group. Thorough clinical examination excluded those suffering from chronic heath problems. Height and weight of each one was taken body mass index of determined according to 'Quat...

The larvae of pest attack on all plant parts and cause maximum damage (Pogue, 2002; Nagoshi, 2007; & Bueno et al., 2010).

The performance of human-based systems depends much on the skill of labor that varies person to person within available manpower. Much work has been done on human resource and management, however, allocation of manpower based on their skill yet not investigated. For this purpose, this study considered offline inspection system where inspection is performed by the human labor of varying skill levels. A multi-objective optimization model is proposed based on Time-Varying factors; inspection skill, operation time and learning behavior. Min-max goal programming technique was used to determine the efficient combination of inspectors of each skill level at different time intervals of a running order. The optimized results ensured the achievement of all objectives of inspection station: the c...

This study was conducted to compare changes in baseline strength of hair after treating it with hard water and deionized water. Hardness level of water samples collected from 10 districts of KP, Pakistan was determined, and that with maximum hardness was considered our sample hard water. Hair samples of 70 male individuals, from district with minimum hardness levels, were collected. Each hair sample was divided into three equal parts, and three groups of hair were established, each group containing 70 hairs. Group A was considered control. Group B was treated with deionized water and Group C was treated with hard water. Tensile strength of all three groups was measured using the universal testing machine and compared using paired -test. The mean age of all 70 participants were 23.87 ± 3. The mean values of tensile strength for hairs of Groups A, B, and C were 255.49, 254.84, and 234.16 with a standard deviation of 57.55, 58.74, and 56.25, re...

Soil samples were collected from top-slope, midslope and bottom slope positions at horizon-A, B and C. Results showed a significant difference among the physicochemical properties of top, mid and bottom slope soils. Bulk density of the top-slope (1.51 g cm-3) was the highest followed by mid (1.39 g cm-3) and bottom slopes (1.32 g cm-3). Conversely, electrical conductivity EC-2.47 dS m-1), phosphorus (3.40 mg kg-1), Potassium (118.8 mg kg-1), Organic matter content (1.52 %), clay content (20.39 %) and silt content (49.17%) were the highest at bottom slope followed by mid and top-slopes, respectively. Soil A, B and C horizons were also significantly (p<0.05) different in their physico-chemical properties. Mean values showed that horizon Ap had the highest bulk density (1.43 g cm-3) and lower electrical conductivity (1.74 dS m-1), phosphorus (2.29 mg kg-1), potassium (84.86 mg kg-1), organic matter (1.08%), clay (12.83%) and silt content (40.49%) than both the B and C horizons. The deterioration in physico-chemical properties of top slope as compared to mid and bottom slopes and that of Ap horizon as compared to B and C horizons were presumed to be due to past soil erosion effect that removed the finer soil particles including soil organic matter and other plant nutrients. This study concluded that increasing extent of erosion due to slope effect can further deteriorate soil properties. The control of such damaging effects would require soil conservation strategies such as proper land levelling, afforestation, terracing and inclusion of restorative crops in cropping systems on these lands.

Different time correlated quantum memory channels are considered to analyze the Nash equilibrium payoff of the 1st player. It is seen that the Nash equilibrium payoff is substantially enhanced due to the presence of correlated noise. The behaviour of damping channels (amplitude damping and phase damping) is approximately similar. However, bitphase flip channel heavily influences the minority game as compared to other channels in the presence of correlated noise. On the other hand, phase flip channel has a symmetrical behaviour around 50% noise threshold. The significant reduction in payoffs due to decoherence is well compensated due to the presence of correlated noise. However, the Nash equilibrium of the game does not change in the presence of noise. It is seen that in case of generalized amplitude damping channel, entanglement plays a significant role at lower level of decoherence. The channel has less dominant effects on the payoff at higher values of decoherence. Furthermore, amplitude damping and generalized amplitude damping channels have almost comparable effects at lower level of decoherence (p < 0.5). Therefore, the game deserves careful study during its implementation due to prominent role of noise for different channels.

But at the same time he was thinking and talking to himself – “Will that idea of building a pharmaceutical on this land will be as fulfilling as his early experience had been with setting up a successful Pharmaceutical distribution venture from scratch?” N.R Enterprises and Pharmic Enterprises had grown to be one of the largest pharmaceutical distribution services in Karachi with revenue more than 400 million annually. The services mainly provided to Institutional organizations across Pakistan for pharmaceutical related products such as medicines and surgical items. The clientele included major pharmaceutical companies in Pakistan both national and Multinational players. The journey to achieve this success had not been very easy. Muhammad Ramzan had a price to pay for such a fast g...

It is shown that the entanglement of initial state is heavily influenced by quantum correlations. It is seen that quantum memory compensates the loss of entanglement generated caused by the Unruh effect. It is interesting to note that the sudden death of entanglement disappears for any acceleration for higher values of memory. Therefore, it is possible to avoid ESD in non-inertial frames due to the presence of quantum memory. Furthermore, the degree of entanglement is enhanced as we increase the degree of memory and it maximizes for maximum correlations.
