    This paper presents the tensile strength of woven kenaf fiber reinforced polyester composites. The as-received yarn kenaf fiber is weaved and then aligned into specific fiber orientations before it is hardened with polyester resin. The composite plates are shaped according to the standard geometry and uni-axially loaded in order to investigate the tensile responses. Two important parameters are studied such as fiber orientations and number of layers. According to the results, it is shown that fiber orientations greatly affected the ultimate tensile strength but it is not for modulus of elasticity for both types of layers. It is estimated that the reductions of both ultimate tensile strength and Young’s modulus are in the range of 27.7-30.9% and 2.4-3.7% respectively, if the inclined fibers are used with respect to the principal axis

    This research study aims to explore the sociocultural analysis ofdehumanization in Khaled Hosseini’s The Kite Runner. The findings of thisstudy show that Hazaras are dehumanized by Pashtuns for a few reasonsamong which the most important reason is their historical background. Thestudy highlights that other reasons for the dehumanization of Hazaras byPashtuns are their low economic and less powerful status, the difference inreligious beliefs, physical appearance, immigrant status, and illiterateness.This study explores that these incidents made Hazaras subordinatedpolitically, socially, economically as well as religiously. Based onSociocultural theory, this article uses a methodological approach based onclose textual reading to analyze the narrative structure of the novel. Usingclose textual reading analysis, this article investigates how Hazaras areothered in society. As a result of these incidents, Hazaras are completelyothered in society which is depicted by Khalid Hosseini in the novel throughthe prejudice and negative behaviors of Pashtun characters towards Hazaras.The Repercussion of dehumanization can be examined in The Kite Runnerwritten by Khaled Hosseini (2003). The after-effects of the dehumanization ofHazaras by Pashtuns resulted in racial discrimination, dehumanization,sexual abuse, religious conflict, socio-political conflict, and economic conflict.The repercussion of dehumanization can be observed in the novel throughdifferent characters such as Ali, Hassan, Baba, Sanaubar, and Sohrab.Through these different characters, the Hazaras are presented as enslaved byPashtuns, objectified, sexually abused, and dehumanized for no good reasonbut racial differences

    Financial inclusion and energy productivity: evaluating the role composite risk for E7 countries

    The global temperature has been on the rise in recent times. Due to the worsening environmental quality and greenhouse gas emissions, countries around the globe are looking for energy productivity. Various countries have successfully promoted cleaner technologies. This study empirically examines the determinants of energy productivity for the panel of seven emerging economies during 2004–2019 to understand why some countries are more energy productive compared to others. This study contributes to the previous literature by identifying the new influencing factors for a selected set of emerging countries that help import universal suggestions for improving energy productivity, green growth, and sustainable development. Using an Augmented Mean Group (A.M.G.) approach, the results suggest that financial inclusion (F.I.N.I.N.C.), globalisation (G.L.B.), human capital index (H.C.I.), composite risk index (C.R.I.) and income are important factors contributing to energy productivity in sample countries. Specifically, an increase in one unit’s F.I.N.I.N.C. brings about a 3% increase in the value of energy productivity. Hence, we conclude that a well-functioning financial system is important in achieving sustainable development goals (S.D.G.s)

    This study investigates the contagion and globalization between the South Asian (Pakistan, India, Bangladesh and Sri Lanka) and five largest economies (US, UK, China, Japan and Germany) stock markets. Daily stock returns data from 1st July 1997 to 30th June 2015 consisting of total 4695 observation is analyzed. DCC GARCH is applied to calculate the conditional correlation coefficients to overcome the issue of heteroscedasticity. Null hypothesis of no globalization got rejected eleven times out of twenty while the hypothesis of no contagion got rejected six times. Further analysis of conditional correlation coefficients confirmed the impact of 9/11 attacks, Subprime mortgage crises and Europeans debt crises on the Indian market. Impact of 9/11 attacks also found on Pakistani and Sri Lankan stock exchanges, while Dhaka stock exchange remained independent of all shocks. In sum, the South Asian stock markets remained isolated from the global shocks except India. Isolation of South Asian stock markets from the global shocks is due to their lower integration with the global markets. This study provides some useful recommendations to the investors and policy makers. Results suggests that Indian stock exchange get contagion impact from the major economies, so authorities of India should have to take measure to decouple the market from the global shocks. The markets of Bangladesh, Sri Lanka and Pakistan are not properly integrated with global financial system, so the authorities of these countries should have to take proper steps to liberalize the markets. This paper presents the first empirical study on financial contagion and globalization of South Asian countries.peer-reviewe

    Perception of the healthcare professionals towards the current trauma and emergency care system in Kabul, Afghanistan: A mixed method study

    Get PDF
    Background: Trauma and injury contribute to 11% of the all-cause mortality in Afghanistan. The study aimed to explore the perceptions of the healthcare providers (pre and in-hospital), hospital managers and policy makers of the public and private health sectors to identify the challenges in the provision of an effective trauma care in Kabul, Afghanistan.Methods: A concurrent mixed method design was used, including key-informant interviews (healthcare providers, hospital managers and policy makers) of the trauma care system (N = 18) and simultaneous structured emergency care system assessment questionnaire (N = 35) from July 15 to September 25, 2019. Interviews were analyzed using content analysis approach and structured questionnaire data were descriptively analyzed.Results: Four themes were identified that describe the challenges: 1) pre-hospital care, 2) cohesive trauma management system, 3) physical and human resources and 4) stewardship. Some key challenges were found related to scene and transportation care, in-hospital care and emergency preparedness within the wider trauma care system. Less than 25% of the population is covered by the pre-hospital ambulance system (n = 23, 65.7%) and there is no communication process between health care facilities to facilitate transfer (n = 28, 80%). Less than 25% of patients with an injury requiring emergent surgery have access to surgical care in a staffed operating theatre within 2 h of injury (n = 19, 54.2%) and there is no regular assessment of the ability of the emergency care system to mobilize resources (human and physical) to respond to disasters, and other large-scale emergencies (n = 28, 80%).Conclusion: This study highlighted major challenges in the delivery of trauma care services across Kabul, Afghanistan. Systematic improvement in the workforce training, structural organization of the trauma care system and implementing externally validated clinical guidelines for trauma management could possibly enhance the functions of the existing trauma care services. However, an integrated state-run trauma care system will address the current burden of traumatic injury more effectively within the wider healthcare system of Afghanistan

    Optimization and Characterization of Novel and Non-Edible Seed Oil Sources for Biodiesel Production

    Get PDF
    Biodiesel mainly comes from edible oil, and there is little research on its yield from non-edible sources with low-cost oil. It is paramount to investigate the non-edible oil resources which may lead to advance the commercial feasibility of biodiesel and cost effectiveness as well as resolve the food issues. This chapter describes four novel non-edible seed oil sources comprising Koelreuteria paniculata, Rhus typhina, Acacia farnesiana and Albizzia julibrissin for biodiesel production. We aimed to optimize different reaction parameters for oil extraction, alkali-catalyzed transesterification process for maximal biodiesel production and finally evaluate its compatibility with mineral diesel. The optimization factors in transesterification included the molar ratio of methanol to oil, reaction time, stirring intensity, catalyst concentration and temperature. Two methods have been described including Soxhlet and mechanical for extraction of seed oil. The synthesized esters were evaluated and characterized through the nuclear magnetic resonance (NMR; 1H and 13C), Fourier transform infrared (FT-IR) and gas chromatography–mass spectrometry (GC–MS) and the total conversion of crude oil to fatty acid methyl esters (FAMEs) were established. The inductively coupled plasma-optical emission spectrometry (ICP-OES) and Elemental Analyzer (EA) were used for evaluation of elemental concentration. The physico-chemical characterizations of the biodiesel, i.e., flash point, pour point, cloud point, and density were within the American Society for Testing and Materials (ASTM; D6751) and European Standards ((EN14214). Koelreuteria paniculata produced highest biodiesel oil content by Soxhlet extraction (28–30%) followed by the Albizzia julibrissin (19–24%), Acacia farnesiana (23%), Rhus typhina (20–22%). The density ranged from 0.83–0.87 @ 15°C (g/cm3) and the kinematic viscosity ranged from 3.75–6.3 (mm2/s) among all the plant sources. Koelreuteria paniculata had highest Na (5456.2), Cr (1246.8), Ni (658.36), and Al (346.87) elemental concentrations (μg/g) than other plant sources. The elemental percent of C, H, N, and O of biodiesel ranged from 72.54–76.86, 11.25–13.34, 1.97–2.73, and 9.86–12, respectively. In conclusion, these non-edible plant seeds offer a cheap source of renewable energy and can be easily grown on barren and wastelands and contribute to efficient biodiesel production to mitigate the energy crisis

    Drivers of climate variability and increasing water salinity impacts on the farmer’s income risk with future outlook mitigation

    Purpose The main aim of this study is to investigate the impact of climate change and water salinity on farmer’s income risk with future outlook mitigation. Salinity and climate change are a threat to agricultural productivity worldwide. However, the combined effects of climate change and salinity impacts on farmers' income are not well understood, particularly in developing countries. Design/methodology/approach The response-yield function and general maximum entropy methods were used to predict the impact of temperature, precipitation and salinity on crop yield. The target minimization of total absolute deviations (MOTAD)-positive mathematical programming model was used to simulate the impact of climate change and salinity on socioeconomic and environmental indicators. In the end, a multicriteria decision-making model was used, aiming at the selection of suitable climate scenarios. Findings The results revealed that precipitation shows a significantly decreasing trend, while temperature and groundwater salinity (EC) illustrate a significantly increasing trend. Climate change and EC negatively impact the farmer's income and water shadow prices. Maximum reduction in income and water shadow prices was observed for A2 scenario (−12.4% and 19.4%) during 2050. The environmental index was the most important, with priority of 43.4% compared to socioeconomic indicators. Subindex amount of water used was also significant in study area, with 28.1% priority. The technique for order preference by similarity to ideal solution ranking system found that B1 was the best climatic scenario for adopting climate change adaptation in the research region. Originality/value In this study, farmers' income threats were assessed with the aspects of different climate scenario (A1, A1B and B1) over the horizons of 2030, 2040 and 2050 and three different indicators (economic, social and environmental) in Northwestern region of Pakistan. Only in arid and semiarid regions has climate change raised temperature and reduced rainfall, which are preliminary symptoms of growing salinity.publishedVersio
