The Impacts of Demographic Factors, Household Characteristics and Locational Factors on Poverty in Pakistan
No full textPoverty refers to lack of basic necessities such as shelter food, and clothing. Poverty is mostly observable in Pakistan, therefore its measurement and analysis deserve claim on our attention. The aim of the study is to examine the impacts of demographic factors, household characteristics and locational factors on poverty in Pakistan. Logistic regression model has been used to achieve this objective. The data for the study is obtained from PSLM survey covering period 2014 to 2015. Findings of the study revealed that household head education, household size, household head age, marital status, health status, remoteness, region and gender have significant impacts on poverty level. The study finds that due to differences in region, gender, and provinces causes rise in poverty rate due to low health facilities, poor educational system, low infrastructure, low employment opportunities and low economic growth. Findings of the study recommend that government should take measures to improve basic facilities, quality education, employment opportunities and health facilities in remote areas of Pakistan
A study of the changing role of the Balochistan Textbook Board
No full textAfter the 18th Constitutional Amendment the role of all provincial Textbook Boards has changed. Since no study has been conducted so far to understand changing role of the Balochistan Textbook Board, this study investigates the changing role of Balochistan Textbook Board after the 18th Constitutional Amendment. This qualitative study comprises semi-structured interviews, focused group discussions and analysis of relevant documents. The study uses a purposive sampling strategy. The study finds that the changing role of Balochistan Textbook Board has helped in developing a sense of responsibility and ownership, making progress in textbooks development and speeding up the process of textbooks development including improving the quality of textbooks. However, the Balochistan Textbook Board has faced some challenges. These include; limited capacity, lack of effective coordination with different stakeholders, lack of teachers’ effective participation in textbooks development, lack of effective evaluation and to ensure quality of textbooks. The study recommends effective coordination among the stakeholders, effective participation of different stakeholders, effective evaluation process, and devising new strategies and mechanisms for textbooks development
Scoping review of the current state of low back pain research in Pakistan
No full textIt is important to know what evidence is available for LBP management in Pakistani population to avoid duplication of research endeavours. The scarcity of resources for conducting research in Pakistani population dictates that impactful research questions are pursued. Therefore, this review aims to summarize the scope, and map the current state of back pain research in Pakistan. It will identify gaps in the literature to provide recommendations for future research

(R1992) RBF-PS Method for Eventual Periodicity of Generalized Kawahara Equation
No full textIn engineering and mathematical physics, nonlinear evolutionary equations play an important role. Kawahara equation is one of the famous nonlinear evolution equation appeared in the theories of shallow water waves possessing surface tension, capillary-gravity waves and also magneto-acoustic waves in a plasma. Another specific subjective parts of arrangements for some of evolution equations evidenced by findings link belonging to their long-term actions named as eventual time periodicity discovered over solutions to IBVPs (initial-boundary-value problems). Here we investigate the solution’s eventual periodicity for generalized fifth order Kawahara equation (IBVP) on bounded domain in combination with periodic boundary conditions numerically exploiting mesh-free technique called as Radial basis function pseudo spectral (RBF-PS) method
Hydrogenation of Xylose to Xylitol in the Presence of Bimetallic Nanoparticles Ni3Fe Catalyst in the Presence of Choline Chloride
No full textHydrogenation of sugars to sugars alcohols is of prime interest for food applications for instance. Xylose obtained from the hemicellulose fraction of lignocellulosic biomass can be hydrogenated to xylitol. Herein, we conducted catalytic hydrogenation reactions in a non-conventional media approach by using choline chloride, a non-toxic naturally occurring organic compound that can form a deep eutectic solvent with xylose. Acknowledging the benefits of cost-effective transition metal-based alloys, Ni3Fe1 bimetallic nanoparticles were utilized as a hetero-catalyst. Under optimized reaction conditions (110 °C, 3 h and 30 bar H2), a highly concentrated feed of xylose (76 wt.%) was converted to 80% of xylitol, showing the benefit of using choline chloride. Overall, the catalytic conversion activity and the product selectivity in the substrate-assisted DES media are relatively high but, the recyclability of the catalyst should be improved in the presence of such media
Efficient Nickel-Iron bimetallic nanoparticles catalysts for the selective hydrogenation of biomass-derived sugars to sugar alcohols
No full textInternational audienceHerein, we demonstrate that a bimetallic nickel-iron based nanoparticles synthesized by simple one-pot hydrothermal method was active and selective in the hydrogenation of sugars to sugar alcohols. To investigate the catalytic performance of NixFey bimetallic nanoparticles, hydrogenation reactions were performed in water starting from biomass derived monosaccharides (xylose, mannose, rhamnose, arabinose, galactose). The molar Ni:Fe ratio was studied and it appears that a bulk composition of Ni:Fe of around 3:1 is active in such reactions. Hence, the Ni3Fe1 BMNPs gives high yield (99%) of corresponding sugar alcohols (with selectivity up to 99%) under mild conditions. The efficient catalytic activity of Ni3Fe1 BMNPs is ascribed to the synergistic actions of Ni and Fe bimetallic composition. The catalyst was recyclable up to 9 consecutive cycles. Furthermore, the catalytic potential of Ni3Fe1 bimetallic nanoparticles was demonstrated starting from different monosaccharides to produce sugar alcohols
Heat transfer analysis of generalized second-grade fluid with exponential heating and thermal heat flux
No full textAbstract The aim of present work is to apply the Caputo–Fabrizio fractional derivative in the constitutive equations of heat transfer. Natural convection flow of an unsteady second grade fluid over a vertical plate with exponential heating is discussed. The generalized Fourier law is substituted in temperature profile. A portion of the dimensionless factors are utilized to make the governing equations into dimensionless structures. The solutions for temperature and velocity profiles of Caputo–Fabrizio model are acquired through the Laplace transform method. These solutions are greatly affected through the variation of different dimensionless variables like Prandtl number, Grashof number, and second-grade fluid parameter. Finally, the influence of embedded parameters is shown by plotting graphs through Mathcad. From the graphical results it is concluded that, the temperature of the fluid decreases with the increasing values of the Prandtl number and Second grade fluid parameter and increases with the passage of time. The velocity of the fluid increases with increasing values of the Grashof number, second grade parameter and time while decreases with increasing values of fractional parameter and Prandtl number
