Nipah virus has caused recurring outbreaks in central and northwest Bangladesh (the “Nipah Belt”). Little is known about roosting behavior of the fruit bat reservoir, Pteropus giganteus , or factors driving spillover. We compared human population density ecological characteristics case villages control (no reported outbreaks) to understand their role P. ecology spillover risk. Belt have a higher ( P < 0.0001), forests that are more fragmented than elsewhere (0.50 versus 0.32 patches/km 2...

Summary Flying foxes Pteropus spp. play a key role in forest regeneration as seed dispersers and are also the reservoir of many viruses, including N ipah virus B angladesh. Little is known about their habitat requirements, particularly S outh A sia. Identifying preferences could assist understanding risk zoonotic disease transmission broadly and, Bangladesh, help explain spatial distribution human Nipah cases. We analysed characteristics giganteus roosts constructed an ecological niche model...

Knee osteoarthritis (OA) is a prevalent condition causing significant disability, particularly among the elderly, necessitating advancements in diagnostic methodologies to facilitate early detection and treatment. Traditional OA diagnosis, relying on radiography physical exams, faces limitations accuracy objectivity. This underscores need for more advanced methods, such as machine learning (ML) deep (DL), improve classification. research introduces novel ensemble approach image data feature...

Integrating different types of renewable energy sources in the power system substantially challenges quality (PQ), directly affecting system's stability and service life span. The rise disturbances (PQD) generates irregularities voltage current waveforms, harming smart grid networks linked devices. Traditional methods for PQD classification use complicated feature extraction techniques, which can be computationally expensive lack scalability. This research proposes applying basic...

The United Nations (UN) Sustainable Development Goals (SDGs) serve as a blueprint for securing sustainable, healthy, and just future people the environment. Through implementation of various policies initiatives Vision 2030, Kingdom Saudi Arabia has significantly advanced its SDGs. Geographic information systems (GIS) remote sensing (RS) technologies can play vital roles in tracking assessing progress government measures. This study investigated potential satellite-based RS GIS planning,...

This paper represents the prospect of mustard oil as a renewable and alternative fuel. To cope up with present load-shedding situation to reduce dependency on imported fuel, Bangladesh government is encour- aging use energy sources. Since diesel engines have versatile uses including small irrigation pumping systems, standby electricity generators, fuel much higher than any other gasoline fuels. In has been in edible throughout country. Mustard widely growing plant every year production seed...

As the adoption of photovoltaic (PV) technology grows, need for sustainable waste management becomes imperative. In this study we investigated different physical route recovery methods such as crushing recycling, high voltage pulse, laser irradiance, and hot knife processes, targeting retrieval valuable materials like silicon, metals, glass, encapsulants. By reviewing existing literature, assess technical viability these techniques highlight their limitations. The technique demonstrates...

Two solar water heaters of 100 liter and 200 were installed on the roof-top electronics laboratory at Old Academic Building (OAB) Electrical Electronics Engineering Department BUET. The data 12 months have been collected analyzed in this paper. It is found that incoming hot tap about 30℃ higher than room temperature during day time winter months. This 25℃ afternoon hours.

Detection of minor faults in power transformer active part is essential because may develop and lead to major finally irretrievable damages occur. Sweep Frequency Response Analysis (SFRA) an effective low-voltage, off-line diagnostic tool used for finding out any possible winding displacement or mechanical deterioration inside the Transformer, due large electromechanical forces occurring from fault currents Transformer transportation relocation. In this method, frequency response a taken...

The aim of this paper is to find the optimum tilt angle solar PV panel at which yearly demand would be met maximum. Solar one most widely used renewable energy resources. output a highest when incident ray perpendicular plane. Due variations in locus sun over year, alignment should changed according position for maximum generation. However, changing needs single axis tracker or double axes costly and also maintenance; thus may not suitable. Therefore, kept average year time. This termed as...

Polyethylene Terephthalate (PET), a polyester based thermoplastic polymer, is used worldwide for packaging foods and beverages. The sharp rise of PET application has increased potential hazards on human health environment. main objective the study was to determine amount plastic waste that generated from bottled drinking water consumption in Kingdom Saudi Arabia, its impact carbon footprint (CO2 generation). An online random survey conducted estimate daily province KSA, Tabuk. total (PET)...

This paper examines the end-of-life (EOL) waste management regulations and guidelines of five leading countries—China, USA, India, Japan, Germany—to identify best practices lessons that can enhance Saudi Arabia’s EOL strategies. The study delves into China’s regulatory framework, highlighting its import bans on certain wastes, USA’s manufacturer responsibility requirements for product disposal, India’s engagement informal sector in collection recycling, Japan’s take-back system mandating...

Rotor flux and torque of an induction motor (IM) are decoupled to obtain performance DC motor. The decoupling strategy has been developed in terms stator current components where the core loss is neglected. Many different controllers including fuzzy logic controller (FLC) with neglecting have designed control speed outcome investigation about effect on indirect field oriented (IFOC) concluded that actual not reached reference if Thus, purpose this paper propose a magnetizing instead...

Plant diseases pose significant threats to global food security, necessitating innovative approaches for disease management and crop protection. This abstract provides an overview of the evolving field plant pathology highlights methods aimed at enhancing resistance in crops. Traditional strategies, including chemical pesticides cultural practices, have limitations such as environmental pollution pesticide resistance. In response, advancements led development sustainable effective solutions...

Bangladesh has a projected electricity demand of 10283 MW by the end year 2015. Despite having huge coastline and relatively large area only 100 that is to come from wind power sources. Bulk this generation planned be deployed in coastal adjacent islands. But there are other places interest for generation, which could good means solving crisis Bangladesh. In paper, feasibility different scale 35 studied perspective Wind Power Density (WPD) Plant Capacity Factor (PCF) at turbine heights. Only...

This paper represents the findings from our research in which a series of experiments were conducted on dc current interruption air axial magnetic field provided rare earth magnets mounted test electrodes. The experimental range was as follows: arc voltage 80-100 V, length 5-10 mm, 80-800 A, and applied 35-2400 G. free-burning diameter measured these high-speed photographs. It found that strong can improve capacity air-arc significantly. In experiments, successful switching time both 220 330...
