Present communication presents numerical investigation of magnetohydrodynamic Sisko fluid flow over linearly stretching cylinder along with combined effects of temperature depending thermal conductivity and viscous dissipation. The arising set of flow govern equations are simplified under usual boundary layer assumptions. A set of variable similarity transforms are employed to shift the governing partial differential equations into ordinary differential equations. The solution of attained highly nonlinear simultaneous equations is computed by an efficient technique (shooting method). Numerical computations are accomplished and interesting aspects of flow velocity and temperature are visualized via graphs for different parametric conditions. A comprehensive discussion is presented to reveal the influence of flow parameters on wall shear stress and local Nusselt number via figures and tables.Furthermore, it is observed that magnetic field provides noticeable resistance to the fluid motion while both material parameter and curvature accelerates it. The progressing values of both Eckert number and thermal conductivity parameter have qualitively same effects i.e. they rise the temperature. Additionally, material parameter and curvature parameter increase the coefficient of skin friction absolutely and qualitively similar effects are noticed for Nusselt number against variations in Prandtl number and curvature parameter. On the other hand local Nusselt diminishes for larger values of Eckert number and power law index. The present results are compared with existing literature via tables, they have good covenant with previous results. © 2016 The Authors

Pakistan is very fertile for wheat production but there are problems of yield loss, low grain quality and substandard fodder. Wheat (Triticum aestivum L.) is invaded by several fungal pathogens; many of them are seed-borne. In current study, 29 different seed-borne pathogens were is olated from eight wheat varieties of district Bhimber Azad Kashmir during the years 2014 and 2015. Mycoflora was explored by using Agar plate method (APM), standard blotter method (SBM), washing method (WM) and deep freeze blotter method (DFBM). Deep freezing method showed better results among all protocols. Tilletia tritici (87.5%) and Cladosporium herbarum (87.5%) were more prevalent fungal pathogens on the most wheat varieties. Susceptibility analysis depicted that varieties Fareed-2006, Seher-2006, Lasani-2008 and Millat-2011are most vulnerable for fungal attack and not suitable for growth in this study area. Wheat varieties V4 (Faisalabad- 2008), V7 (Punjab-2011) and V8 (Galaxy-2013) showed least prevalence and these three wheat varieties are cultivated dominantly in the study area. For control measures two chemical and biological methods were used. In chemical protocol fungicides Benlate (56.84%) and Thiabendazole (58.44%) showed good fungal control. In biological treatment, applying plant extracts showed better germination rates (79.5A, 81.6A and 78.2A) in study area in comparison with other treatments. Fungicide treatments also gave better germination rate (77.3A), but are not recommended due to their detrimental and toxic impacts on environment and human health. This study recommends that biocontrol method for elimination of seed mycoflora which is ecofriendly, less costly and easily to handle. It depicts that seed-borne diseases severely affect the biomass and gains quality and quantity of wheat crop. As conclusion wheat variety Galaxy-2013 (0.7EF) showed maximum resistance to seed mycoflora hence it is recommended as the best variety for cultivation in the study area. © 2017, Pakistan Botanical Society.

Ficus genus has medicinally important plant and being used by indigenous communities of Azad Kashmir. In this research, some taxa of Ficus (F. bengalensis, F. carica, F. sermentosa, and F. semicordata) were analyzed to investigate their antimicrobial potential. In antibacterial analysis three strains viz: Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli were tested using negative and positive controls. For antimycotic studies three fungi taxa: Fusarium solani, Aspergillus flavus and Candida albicans were used in compatible with both type of control set up for comparison. In analysis, plant samples were extracted by maceration method using four solvents Petroleum Ether (P.E.), Chloroform, Methanol and water. Two methods viz: Agar Well Diffusion Method and Micro dilution method. Methanol was proved to be the best solvent with highest %age yield. Highest zone of inhibition (ZI) was found for methanolic extract of lead of Ficus bengalensis against S. aereus with 22.3±0.65 mm and AI: 0.94. For fungi maximum ZI was 25.3±0.60 mm against C. albicans. In Ficus bengalensis extracts; most resistant bacterial strains was P. aeruginosa with MBC of 93.5±0.30 µg and most resistant fungus was A. flavus with MFC of 108.6±1.12µg. Among F. carica extracts best ZI was 20.5±0.55 mm and AI of 0.93 agaisnt P. aeruginosa whilst for antimycotic analysis MFC was 51.4±0.60 µg found for F. solani. In analysis of macerates of F. sermentosa; highest ZI (19.7±0.55 mm) was found for E. coli and ZI of 23.1±0.66 mm for C. albicans for methanolic extract. In its extracts, best MBC was 86.9±0.30 µg agaisnt S. aereus and MFC with 95.5±0.85 µg for F. solani. For extract analysis of F. semicordata, good ZI was explored for S. aereus with 19.5±0.80 µg and for fungus activity it was found that methanolic extract had highest ZI (21.3±0.45 mm) for A. flavus. In this plant activity tests, it was found that best MIC (40.5±0.60 µg), MBC (39.5±0.25µg) for E. coli and MFC (99.6±0.55 µg) F. solani. Out all analyzed taxa; methanolic extract of F. bengalensis was found to be best for antimicrobial dose of medication with least MBC and MFC followed by macerates of and F. semicordata. This research reveals that Ficus bengalensis and F. semicordata are more effective agaisnt bacteria and fungi than leaf extracts of Ficus carica and F. sermentosa. The current findings might be useful for preparation of herbal recipes or allopathic medicines by pharmaceutical industries to cure resistant gaining microbes. This will culminate into alternative medicine development by indigenous pharmacopeia for cure of these pathogens with drugs having no-side effects, synergistic in action and easy to purchase. © 2017, Pakistan Botanical Society.

A mathematical model is presented to discuss magnetohydrodynamic Sisko fluid flow over a stretching cylinder with cumulative effects of viscous dissipation and Joule heating in the presence of nanoparticles. The mathematical modelling of the physical problem produced nonlinear set of partial differential equations which are transfigured into simultaneous system of ordinary differential equations with appropriate boundary conditions via suitable scaling group of transforms. Shooting technique is used to solve nonlinear set of flow govern equations. Comparison of numerical solution is made with previously reported data to validate the accuracy. The influence of governing parameters on the velocity, temperature and concentration is discussed under different parametric conditions. The numerically computed results are deliberated via graphs by selecting suitable values of the relevant physical parameters. Additionally to insight physical phenomenon in the vicinity of surface skin friction coefficient, local Nusselt number and local Sherwood number are computed and explicated through tables as well as graphs. © 2017 Elsevier B.V.

A mobile ad hoc network (MANET) is a wireless, dynamic, infrastructure-less, self-organized, multi-hop, and decentralized network. Each node in MANET can act as a router as well as a work station. Many routing protocols have been developed to increase the efficiency of MANET. The primary objective of this paper is a detailed QoS comparison of reactive (AODV), proactive (DSDV), and hybrid (ZRP) routing protocols of MANET in order to find which routing protocol works best in a particular network scenario. The analysis was made for TCP-based traffic patterns. The performance differentials were analyzed on the basis of normalized routing overhead, packet loss, packet delivery ratio, control packets, end-to-end delay, packet received, and packet sent with a variation of nodes density and mobility. The results were obtained using the NS-2 simulator. © 2016 The Chinese Institute of Engineers

A comprehensive analysis of various horticulturally important morphological traits of sixty pear accessions located in five districts of Azad Jammu and Kashmir (Pakistan) was carried out. Several qualitative and quantitative traits were investigated in situ and after the harvesting of leaf and fruit samples. The rich diversity was observed for qualitative traits (i. e. growth habit, blooming time, intensity of flowering, fruit setting, ripening time, productivity, and fruit shape and color) among pear accessions. As for the quantitative traits, significant variation was observed for leaf area (8.96–27.17 cm2), flowering duration (11–24 days), fruit weight (68.1–322.3 g), average fruit length (2.68–9.87 cm) and average fruit width (1.82–8.12 cm) between pear accessions. Based on qualitative and quantitative data, two dendograms were constructed by using cluster analysis which separated pear accessions into three distinct groups. The cluster analysis showed considerable differences between the accessions for qualitative and quantitative traits. Furthermore, a close association between accessions was noted inside the clusters for qualitative and quantitative traits. The results showed rich diversity and similarity between the pear accessions and needs further assessment at molecular level to elucidate their phylogenetic relationship. © 2016 Springer-Verlag Berlin Heidelberg

This study aims at the development of an artificial neural network-based model for the estimation of weekly sediment load at a catchment located in northern part of Pakistan. The adopted methodology has been based upon antecedent sediment conditions, discharge, and temperature information. Model input and data length selection was carried out using a novel mathematical tool, Gamma test. Model training was carried out by using three popular algorithms namely Broyden-Fletcher-Goldfarb-Shanno (BFGS), back propagation (BP), and local linear regression (LLR) using forward selection of input variables. Evaluation of the best model was carried out on the basis of basic statistical parameters namely R-square, root mean squared error (RMSE), and mean biased error (MBE). Results indicated that BFGS-based ANN model outperformed all other models with significantly low values of RMSE and MBE. A strong correlation was also found between the observed and estimated sediment load values for the same model as the value of Nash-Sutcliffe model efficiency coefficient (R-square) was found to be quite high as well.

Currently licensed typhoid vaccines are based on Vi capsular polysaccharides. Recent molecular reports from typhoid endemic countries state that Salmonella enterica serovar Typhi (S. Typhi) Vi negative strains occur naturally and cause typhoid fever which is indistinguishable from disease caused by Vi positive strains. Vaccine based on Vi polysaccharide may not protect patients if the invading S. Typhi are negative for Vi. The lipopolysaccharide (LPS) is an essential component of S. Typhi outer membrane in which O-specific polysaccharide (OSP) is a protective antigen and universal candidate for vaccine development. In this study, S. Typhi Vi negative isolates were discriminated from Vi positive isolates through a duplex PCR using primers of fliC-d (599bp) and tviA (495bp) genes. The LPS of S. Typhi Vi negative isolates was extracted by hot phenol method and OSP was purified by core hydrolysis. The yield of extracted LPS was 91 mg/L and that of purified OSP was 49.14 mg/L of culture broth. LPS showed ladder like appearance by zinc imidazole staining following SDS-PAGE. Whole cell challenged mice sera were used for in vitro antigenicity evaluation of the purified LPS and OSP. The antigenicity was found adequate by immunodiffusion assay. To our knowledge, this is the first report of purification and antigenic evaluation of LPS of a Vi negative S. Typhi isolate. The purified OSP from S. Typhi Vi negative isolate may be coupled with a carrier protein to produce universal low cost conjugate vaccine candidates for use in typhoid endemic regions.
