Abstract : Phosphorus Adsorption Capacity of Four Soil Series for P Requirement of Wheat (Triticum aestivum L)
|
|
|
Abstract: A pot experiment was conducted in order to know the phosphorus requirement of wheat as affected by different levels of phosphorus (P) for obtaining 95% relative yield grown in four soil series i.e. Gishkori, Buzdar, Sultanpur and Tikken of Dera Ismail Khan Khyber Pakhtunkhwa, Pakistan. The various treatment levels were consisted of 0, 5.5, 11.0, 16.5 and 22.0 mg P/kg of soil. Wheat dry matter yield remained at highest (1.1g) where P was supplemented at 22.0 mg P/kg in Gishkori and lowest (0.95g) in Tikken soil with the same P applied level. An increase in phosphorus concentration was recorded in wheat shoot with an increase in applied P level. Maximum phosphorus percentages recorded in wheat were 0.28 and 0.26 grown in Gishkori and Buzdar soil series followed by Sultanpur and Tikken with values of 0.11 and 0.10 respectively against P applied level of 22.0 mg P/kg soil. Minimum P concentration was noted in control. The phosphorus content of wheat and P levels were highly correlated with r values of 0.99. 0.99. 0.98 and 0.74 for Gishkori, Buzdar, Sultanpur and Tikken soil series respectively.

Abstract : “Cues” for Non-Routine Decisions on the Fireground
|
|
|
Abstract: A decision making model for building decision support system is reported here that is developed through working with fireground incident commanders of the United Kingdom. The model is suitable for decision making in non-routine situations. A detailed description of the development of the model is available in Shaikh (2011). There is a need to develop a working prototype decision support systems based on this model particularly for training and helping FGCs working in countries such as Pakistan, Sri Lanka, Indonesia etc. Keywords: Fireground incident commanders, decision making, non-routine, information systems. |
Abstract : Effect of Okra Yellow Vein Mosaic Virus (OYVMV) on Plant Growth and Yield
|
|
|
Abstract: Okra yellow vein mosaic virus (OYVMV) is one of the most destructive diseases of okra plant. In the current study, effect of okra yellow vein mosaic virus (OYVMV) was assessed on plant growth and yield in naturally infected crop under agro-ecological conditions of Hyderabad district. The virus showed the significant reduction in plant height, number of leaves, flowers, fruits, and over all pickings and yield of all the locations wherever the crop was examined in the district. The significant reduction in plant height (48.67 cm) in infected plants as compared to healthy plants (62.96 cm) was recorded. Similarly, significant difference in the flowers formation per plant at all four locations was recorded in diseased (0.912) and healthy (2.165) plants. Fruit weight was also significantly reducing due to the disease prevalence at all four locations (73.25 g) as compared to healthy observed fruits (91.50 g). Interestingly, on overall basis there were more numbers of leaves (20.66) in infected plants as compared to healthy one (16.33). It is obvious from the results that virus (OYVMV) showed significant increase in number of leaves but reduced plant height, flowers, fruits and yield at all four observed locations, thus, pathologists and breeders are advised to work more on evaluation of resistant varieties using advanced molecular tools. The growers are also advised to adopt preventive as well as curative control measures so that the yield losses may be decreased. Keywords: Abelmoschus esculentus L., OYVMV, Growth and yield. |
Abstract : The Effects of Exercise on Perceived Barriers and Benefits of Exercise by Cancer Survivors Post Treatment
|
|
|
Abstract: Exercise may be used to attenuate cancer treatment-related side effects. However, the majority of cancer survivors do not participate in regular exercise. Purpose: This study examined changes in fitness parameters as well as perceived exercise benefits and barriers held by post-treatment adult cancer survivors, who participated in a 12-week structured exercise program. Methods: This study used a randomized controlled trial design. Participants were 24 post-treatment adult cancer survivors with various cancer diagnoses. The Exercise Benefits /Barriers Subscale (EBBS) questionnaire was used to evaluate perceived exercise benefits and barriers. Data was analyzed using a mixed-between-within ANOVA. Results: There were no significant differences in the total EBBS score (128.7 ± 23.2 v. 142.6 ± 17.8; p=.20) or the benefits (86.4 ± 17.2 v. 96.3 ± 12.9; p=.31) and barriers subscales (42.3 ± 7.8 v. 46.5 ± 6.1; p=.14). However, those in the exercise group were significantly more likely to respond that exercise participation would not cause fatigue (2.42 ±.90 v. 3.25 ± .45; p=0.04), but may decrease fatigue (3.0 ± .60 v. 3.17 ±.58; p=.03). Conclusion: Among cancer survivors, exercise participation may strengthen the perception that exercise reduces, rather than causes, fatigue.

Abstract : The Effects of Classical Trapping on the Control of Malaria Transmission
|
|
|
Abstract: This paper investigates the effects of classical trapping on the control of malaria transmission. The Ross-Macdonald model is modified and a trapping probability function is introduced to construct a partial differential equation (PDE) system. The proof of existence and uniqueness of solution of density functions to the PDE system is given, numerical simulation results based on Gaussian distribution and exponential distribution are obtained for the solutions, and graphical representations of solutions are shown and interpreted. Keywords: Trapping Probability, Ross-Macdonald Model, Gaussian Distribution, Mosquito Density, Malaria. |
