A high dopant concentration significantly reduces the peak current of the internal quantum efficiency (IQE) of the light-emitting diode (LED). The effect of the dopant concentration on the epitaxial layer toward the IQE, current density, and IQE droop of gallium nitride (GaN)-based LED chip is analyzed with the doping variation from 1 × 1015 cm−

Wastewater effluent contaminated with heavy metals originating from numerous human and industrial activities is one of the major threats to the environment. Lead (Pb) is one of the common and most toxic pollutants in natural waters. Pb contamination present in water is associated with mining and semiconductor industries pose serious health issues t

The story of ‘Al-Gharaneeq al-‘Ula’ or ‘prominent deities’ concerns about a historical narrative in the early stage of Islam.

Centre for Zakat Management (CZM) introduced a new mechanism of payment, utilization, mobilization and effective distribution of Zakat in an organized and planned manner to achieve significant success in poverty eradication in Bangladesh. CZM adopted prime initiatives for institutionalizing Zakat management system aiming to promote prosperity and r

Burkholderia pseudomallei is a saprophytic Gram-negative bacillus that is found in soil and surface water. It causes the disease melioidosis, which infect humans and animals. Melioidosis can be fatal in human, where it causes fever and commonly present with pneumonia, with or without septicaemia. Melioidosis is primarily endemic in Southeast Asia a

The aim of this study was to identify and verify the potential bacteria as the bioremediation agent. It involved bacteria isolation, identification through Gram staining, analytical profile index (API) test and determine bioremediation activities by using inductively coupled plasma mass spectrometry (ICPMS). The soil and water sample were collected

Introduction: Syzigium cumini has been known to have an anti-microbial effect and is traditionally used as medicine for some human diseases. However, only a few studies were done on water extracts of these leaves. This study aimed to elucidate the minimum inhibition concentration (MIC) and minimum bactericidal concentration (MBC) of water extract o

This book discusses the case of ‘Arafah, Muzdalifah and Mina - which are collectively called in Arabic al-masha’ir al-muqaddasah, or just masha’ir – during the course of some crucial periods of Muslim history. The al-masha’ir al-muqaddasah expression signifies the sacred geographical locations in the vicinity of the holy city of Makkah wh
