Underground Coal Gasification is a non-traditional, in-situ combustion process for converting coal into product gases. In this process coal is combusted and the produced syngas which basically contains CO2, H2, CO and CH4 is extracted to the surface with the help of drilled wells. In this study, with reference to a lab-scaled UCG experiment [1] and taking the experimental data as the basis for the research a two dimensional CFD reactor model was created and further studies were done to establish the activity at the different locations of the reactor.

Energy harvesting is defined as a process of acquiring energy surrounding a system and converting it into electrical energy for usage. Piezoelectric energy harvesting is a very important concept in energy harvesting in microelectronics. In this report, an analysis of the cantilever type piezoelectric energy harvester is conducted using the finite element method (FEM) based software COMSOL Multiphysics. A unimorph type cantilever beam of the silicon substrate, structural steel as proof mass and support, and PZT-5A material as piezoelectric constitute the physical system.

When coherent light rays can be incident on an optically rough object it will scatter randomly through all directions. Interference of these scattered rays leads to the formation of a bright spots (constructive interference), and dark spots (destructive interference), these are called Laser Speckles.

Solid waste management is a burning issue all over Bangladesh. Jahangirnagar University campus is also facing serious problems; especially, open waste dumping. In Jahangirnagar University open solid waste dumping sites are increasing which is illegal and contradictory to the environmental protection act. Solid waste created a toxicant environment which could be affected to the natural environment. In this circumstance, to protect the natural environment modern waste management strategy “clean and green” concept has been accepted in many renowned Universities for the higher education of the world.

Before we discuss the practices of knowledge in youth livelihood projects in EDA it would be relevant to define the philosophy of knowledge (epistemology) first. The philosophy of knowledge is Epistemology, and it is the branch of philosophy concerned with knowledge. Epistemologists study the nature, origin, and scope of knowledge, epistemic justification, the rationality of belief, and various related issues. Epistemology concerns itself with ways of knowing and how we know. The word is derived from the Greek words epistéme and logos – the former term meaning “knowledge” and that latter term meaning “study of” (Donald, 1967).

Sharīʻah Maxims (Islamic Legal Maxims) are such leading principles and regulations in the light of which legal scholars and academic philosophers explore the permissible commands of the enduring issues. One deducted legal rule doesn’t cover up all the situations and matters underneath but its maximum states. The assumption of laws is just by the Qur’Än and the Nobel statements of the Holy Prophet Muhammad (PBUH), or the Ijm’a (Consensus of Opinion), Ijtihad and Qias (Analogy) which are deduced from these sources of the Sharīʻah.

A new variant of the corona virus family found in the Wuhan city market of the China causing serious harm to human being. After the WHO decided COVID-19 as a pandemic situation, everyone has started to measure the prevention from infectious disease according to WHO guidelines. It includes social distancing, isolation, quarantine, lockdown, sanitation and masking respectively. During the time researcher has observed the difficulties of cultivating new normal to people in Nepal. People have perceived the single corona virus differently; common populations and frontline workers have different perception towards to corona virus. Researcher started to measures the psychosocial impact of COVID-19 pandemic into frontline workers and general populations in Kathmandu valley. The total number of sample unit for this research is 82; it includes 52 general populations and 30 frontline workers.

One of the biggest constrains to manage solid waste is to tackle old plastic bags /shoppers. Their decomposition period ranges 10 to 10,000 years in rough statistics. To eliminate these bags from waste stream is a notorious difficulty. So to convert this problem to a product could be a fascinating approach. It is a forward step towards green behavior. It also minimizes dumping loads so it is a space safety measure as well.

Islam and concept of "fate" is interesting for Muslims and non-Muslims as well. Fate and its existence or non-existence is debatable from the beginning of civilizations. A concept is the starting point of a thought, discourse or reasoning. It provides the basis to the faith and belief. Islam is so close to nature and its requirements. Human nature and instinct are well bestowed in Islamic teachings and divine revolution. The concept of fate in Islamic perspective is therefore, needs to elaborate.
