Investigation of helmet use behavior of motorcyclists and effectiveness of enforcement campaign using CART approach
Use of the helmet is beneficial in reducing the severity of injuries and avoiding fatalities for motorcyclists, therefore, legislation exists in almost all countries. In practice, the situation is different regarding the helmet use, especially in the developing countries. This paper investigates the helmet use behavior of motorcyclists in Karachi, [...]
Amino acid functionalized glassy carbon electrode for the simultaneous detection of thallium and mercuric ions
Mercury and thallium forms a eutectic alloy that finds extensive use in thermostatic devices owing to its capability of withstanding extremely low temperature. As both these metals are highly toxic, so herein we report their co-sensing on a sensitive electrochemical platform. The performance of the designed sensing surface was tested [...]
Enhancing Beaconing Efficiency via Grouping for Vehicular Communications
To enhance transportation systems’ safety, vehicles have to periodically broadcast authenticated beacons on a dedicated limited wireless medium; beacons include vehicles’ current status. To provide the required authentication, the Public Key Infrastructure (PKI) security framework has been embraced; PKI has a significant authentication overhead that consumes the limited wireless medium. [...]
Biochemical Conversion of Microalgae Biomass into Biofuel
Biofuel production via microalgae is a promising and sustainable alternative to replace the typical fossil fuel that is the main contributor to the global warming. However, for a cost-effective biofuel production, further advanced research is still needed for large-scale operation. This article is a tutorial review on conversion processes of [...]
Pyrolysis of Expanded Waste Polystyrene: Influence of Nickel-Doped Copper Oxide on Kinetics, Thermodynamics, and Product Distribution
In this study, pyrolysis of waste polystyrene was investigated in the presence of a mixed metal oxide (Nix=0.5Cu1-xO) under inert conditions in a pyrolysis chamber. The pyrolysis products were collected and analyzed by gas chromatography/mass spectrometry. Kinetic parameters were determined from thermogravimetric data, and the activation energy and pre-exponential factor [...]
What Drives Remittances from Saudi Arabia to Pakistan? Home Versus Host Country’s Economic Conditions
Saudi Arabia is the largest source country of remittances to Pakistan since the 1970s. This study examined the impact of home versus host country’s economic conditions on remittances from Saudi Arabia to Pakistan. The ARDL bounds testing is used on the annual data set from 1973 to 2014. The study [...]
Contribution of International Trade in Human Development of Pakistan
Very few studies have attempted to examine the relationship between international trade and human development. Some panel and cross-section studies have been done, but mostly Pakistan has not been included. This study examines for the first time ever the effect of aggregate and disaggregate trade on human development in Pakistan [...]
Smart PV grid to reinforce the electrical network
Photovoltaic (PV) became the new competitive energy resources of the planet and needs to be engaged in grid to break up the congestion in both Distribution and Transmission systems. The objective of this research is to reduce the load flow through the distribution and transmission equipment by 20%. This reduction [...]
Fitting school buildings to the requirements of physically disabled students in Algeria: An ergonomic study
Achieving development in any country is a joint responsibility and needs intensive efforts from all citizens; the able-bodied and the disabled. But how can people with disabilities contribute to this development if their work and environment are not fitted to them? In Algeria, according to the Algerian National Office of [...]
Gender differences in relation to organization sources of power: An exploratory research of individuals and contextual issues
Women encounter more challenges than men in their attempts to reach top managerial positions. Challenges stem from proscribed social roles, employed life strategies, and/or organizational structures. The same challenges lead men and women to use organizational sources of power differently. This qualitative research examines gender differences in relation to individual [...]
