Abstract: Cotton is more sensitive to low K availability than most other major field crops, and often shows symptoms of K deficiency in soils not considered K deficient. Field investigation was conducted at Sahiwal to study the effect of different rates of K and Na application on seed cotton yield, ionic ratio and quality characteristics of two cotton varieties. Ten soil K: Na ratios were developed after considering indigenous K, Na status in soil. The treatments of K+Na in kg ha-1 to give K:Na ratios were as: 210+ 60 (3.5:1) i.e. control, 225 + 60 (3.75:1), 240 + 60 (4:1), 255 + 60 (4.25:1), 270 + 60 (4.5:1), 210 + 75 (2.8:1), 225 + 75 (3:1), 240 + 75 (3.2:1), 255 + 75 (3.4:1) and 270 + 75 (3.6:1). Control treatment represented indigenous K, Na status of soil. The experiment continued until maturity. Maximum seed cotton yield of NIBGE-2 was observed at K: Na ratio of 3.6:1. Variety NIBGE-2 manifested greater seed cotton yield than MNH-786. Leaf K: Na ratio of two cotton varieties differed significantly (p < 0.01) due to varieties, rates of K and Na and their interaction. Variety NIBGE-2 maintained higher K: Na ratio than MNH-786 and manifested good fiber quality. There was significant relationship (R2 = 0.55, n = 10) between K: Na ratio and fiber length and significant relationship (R2 = 0.65, n = 10) between K concentration and fiber length for NIBGE-2. There was also significant relationship (R2 = 0.91, 0.78, n = 10) between boll number and seed cotton yield for both varieties. The increase in yield was attributed to increased boll weight.

Abstract: Objective: To assess the potential of oral Clonidine premedication indecreasing patient discomfort during the injection of Propofol. Design: This was a comparative study of 80 ASA class1 and II. Place and Duration of study: This study was carried out at Combined Military Hospital, Kharian. Patients andMethods: This was a study of 80 ASA class 1 and 2 patients of similar age group. Patients selected were from amongstthose undergoing elective gynaecological surgery, specifically Diagnostic Dilatation and Curettage. These patients wereselected by non-probability convenience sampling. The patients were randomly assigned, by means of a random table,to one of the two groups of 40 patients each. Group ‘A’ patients were given oral Clonidine, 300mg two hours beforeinduction of anaesthesia by Propofol injection. Group B’ patients were given 0.01 to 0.02mg/kg plain Lidocaine justbefore Propofol induced anaesthesia. Non-invasive systolic arterial blood pressure (ni-SBP), non-invasive diastolicarterial blood pressure (ni-DBP) and heart rate were recorded in the ward about 120 min [before administration of oralClonidine in group-A] in both groups. Measurements were repeated in the operating theatre before induction ofanaesthesia. Patients in Group-A were given one tablet Catapres [Clonidine, 300mg] with a sip of water, two hoursbefore induction of anaesthesia and they were observed in the Post Anaesthesia Care Unit during this period, whiletheir pulse and blood pressure were monitored. Patients in group-B were not premedicated with Clonidine. They wereinjected 0.01 to 0.02mg/kg injection plain lidocaine, through the injection port of an 18-gauge cannula, as premedicationjust before propofol monitoring was done as for group-A. Before administration of propofol, the patient was requestedto rate immediately any sensation of pain during injection as none (0), mild (1), moderate (2) or severe (3), also calledthe Verbal Rating Scale (VRS). Results: The results showed both groups to have similar pain score, and differenceswere deemed statistically not significant by the analysis. Conclusion: Our results imply that Clonidine makes anexcellent premedication with Propofol for short gynaecological procedures.

Abstract: Ficus infectoria has a wide distribution in Bangladesh, Nepal, Pakistan, Sri Lanka, Southwest China and Indochina and is an enrich source of phytochemicals thereby possess antibacterial, antifungal and hyperglycaemic activities. In this study, we attempted to examine the cognitive ability of methanolic and ethanolic extract of F. infectoria fruit extract in scopolamine induced memory impairment in mice by using preliminary phytochemical and antioxidant tests, and the cognitive ability of the methanolic and ethanolic fruit extract of F. infectoria. Fruit extract was analyzed in scopolamine amnesia mice using passive avoidance approach. Piracetam was used as a reference drug (200 mg/Kg). Further confirmation was provided by means of mice brain homogenate biochemical tests. Maximum phytochemical, antioxidant activity and nootropic ability were observed in the ethanolic fruit extract of F. infectoria. Plant extract was used at three doses i.e. 75 mg/Kg, 150 mg/Kg and 300 mg/Kg and exhibited nootropic abilities in all tests used. Enhanced SDL value i.e. (291.2 ± 0.33+++###) was observed by the administration of plant extract at all dose range in comparison to reference drug i.e. piracetam (252.8 ± 1.60###) used in the study. The plant extract utilization has showed increase in total protein (25.08 ± 0.26+++### mg/g of tissue) and reduced glutathione content (33.0 ± 0.46+++### nmoles/mg of protein) and vice versa while low malondialehyde (MDA) (9.18 ± 0.17+++### nmoles/mg of protein) and AChE activity (0.067 ± 0.009+++### M/min/g protein). However, opposite situation was observed in the scopolamine amnesia mice. Hence it was concluded the plant extract possessed neuroprotective activity in the scopolamine induced cognitive decline in mice thereby used as cost effective natural medicines in near future.

Abstract: Unmanned Aero Vehicles (UAV) has become a useful entity for quite a good number of industries and facilities. It is an agile, cost effective and reliable solution for communication, defense, security, delivery, surveillance and surveying etc. However, their reliability is dependent on the resilient and stabilizes performance based on control systems embedded behind the body. Therefore, the UAV is majorly dependent upon controller design and the requirement of particular performance parameters. Nevertheless, in modern technologies there is always a room for improvement. In the similar manner a UAV lateral control system was implemented and researched in this study, which has been optimized using Proportional, Integral and Derivative (PID) controller, phase lead compensator and signal constraint controller. The significance of this study is the optimization of the existing UAV controller plant for improving lateral performance and stability. With this UAV community will benefit from designing robust controls using the optimized method utilized in this paper and moreover this will provide sophisticated control to operate in unpredictable environments. It is observed that results obtained for optimized lateral control dynamics using phase lead compensator (PLC) are efficacious than the simple PID feedback gains. However, for optimizing unwanted signals of lateral velocity, yaw rate, and yaw angle modes, PLC were integrated with PID to achieve dynamical stability.

International Journal of Conservation Science , 2013,
Abstract: The present study was conducted to estimate the status of common leopard (Panthera pardus) in and around Machiara National Park (MNP) Azad Jammu and Kashmir between May 2007 and July 2008. Fifteen fixed transects were monitored on regular basis. Indirect signs of leopard such as pugmarks and scats were recorded along the transects in addition to people and livestock which were counted as an index of disturbance and mean encounter rate for leopard scats, footprints, livestock and people was calculated. Mean encounter rate for leopard pugmarks was 1.6, for scats 2.11, for livestock 25.03, and for people 22.48. Linear measurements of front and hind pugmarks and strides were classified which indicated that at least six to nine (06-09) individuals are present in the study area (13,532 ha). Questionnaire survey revealed that Leopards were sighted by the locals at 23 locations during the study period including; in the morning (35%), evening (29%), night (21%) and daytime (15%). Maximum sightings were recorded between 4765ft to 9634ft elevation presenting moist temperate zone with Pinus wallichiana as a dominant tree species. As a result of increasing biotic pressures, the leopard has become rare with growing threat of further degradation and fragmentation of its habitat. It may cause the species to depend more on the domestic livestock available in and around the area giving way to the problem of human-leopard conflict. The information generated from the study will be helpful for the conservation and management of this critically endangered species.

Natural Science (NS) , 2010, DOI: 10.4236/ns.2010.24039
Abstract: The behaviour of poly(methyl methacrylate) was examined in the presence of phosphorus tri-bromide (PBr3) with varying concentrations. Films were cast from common solvent and subjected to TG, DTA, DTG, IR and Py-GC-MS for evaluating the degradation routes. Despite early decomposition of the blends, certain tempera-ture zones were identified for stabilization of the system. New products were found and mecha-nisms of their formation were proposed. Pyro-lysis of the blends was also carried out at dif-ferent temperatures to ascertain the nature of interaction between the constituents of the system.
