The concentration of heavy metals in road dust poses significant risks to human health and the environment. This study investigates the characteristics of road dust, focusing on the contamination level of heavy metals like lead (Pb), iron (Fe), and arsenic (As). Road dust samples were collected from various locations in Khulna city. They went through acid digestion to determine the Pb, Fe, and As levels using ICP-OES, and bioavailable iron was assessed by mixing the dust samples with water. This study found no dete [...]

The incidence of antifungal-resistant pathogenic fungi has steadily increased around the globe and calls for an aggressive response. The study aimed to produce and evaluate virgin coconut oil's phytochemical properties and antifungal potentials (VCO). The production of VCO was achieved by hot extraction and natural fermentation methods. Gas Chromatography-Mass Spectrometry (GC-MS) was used to evaluate the active phytochemicals in the VCO. The antifungal activities of VCO against Aspergillus flavus, Aspergillus nige [...]

This work focuses on designing a control unit for improving Proton Exchange Membrane Fuel Cell (PEMFC) performance powering electric vehicles when operating in variable atmospheric pressure conditions, a current situation in mountainous countries with sudden changes in road altitude. The paper studies and analyzes the PEM fuel cell behavior working with hydrogen supply from a pressurized tank and oxygen input from atmospheric air supply in journeys with continuous variation of road level due to the orography. The w [...]

In this conceptual paper we apply the construct of time poverty to a novel population, farmers struggling with stress and mental health challenges. Farmers have rates of suicide that can be over three times that of the general population, with depression and anxiety at double general population rates. These are linked to the multiple stressors farmers experience due to the unpredictable nature of their work, such as weather, input costs, commodity prices, and government regulations. In addition, there are multiple [...]

This is a conceptual paper comparing how narrative therapy and Buddhist mantra-based meditation promote mental healing. Narrative therapy promotes mental healing by shifting families’ attention to their subjugated stories of strengths and personal agencies. Whilst Buddhist meditation has been integrated into psychotherapy developed in the West, the application is primarily the focus on breath as a way to help sufferers attain mindfulness. Mantra-based meditation uses the recitation of mantra as the focus instead of [...]

Parabolic trough collectors (PTCs) are essential for solar thermal energy systems, and their thermal efficiency can be significantly enhanced using turbulators and nanofluids. This numerical study introduces three novel fin-spiral turbulator configurations (4, 7, and 10 blades) to enhance heat transfer within the absorber tube. Additionally, three nanofluid types including water-based single-walled carbon nanotubes (SWCNT), cupric oxide (CuO), and a hybrid SWCNT-CuO, at concentrations of 1%, 3%, and 5% were evaluat [...]

In the realm of marine meteorology, physical oceanography, and coastal and ocean engineering, the wind-stress across the air-sea interface plays a dominant role. However, under tropical cyclone conditions, there is no consensus for the formulation of the drag coefficient, Cd, in the literature. Based on the wind-gust method and the measurements from data buoy 42001 during Hurricane Lili, it is demonstrated that, U* = 0.073U10 - 0.44, which is valid up to wind speed 47 m s-1 and wind gust to 66 m s-1, here U* is the [...]

The World climate is changing, with a great impact on global food production systems. Extreme weather events, floods, wildfires and draughts are phenomena of disrupted previously stable natural weather patterns, which are vital for crop production and animal husbandry alike. Most of the World’s food is produced in temperate climatic zones rich in arable land and those are affected by the increasing unpredictability of previously naturally occurring seasons and weather conditions. This work aims to provide a possibl [...]

The supraclavicular artery flap presents a promising solution for facial reconstruction challenges since 1997, surpassing limitations of traditional methods like the deltopectoral flap. Its extended pedicle and thin, pliable epidermis offer reliable outcomes with minimal donor site morbidity, making it a preferred choice for head and neck reconstruction. This systematic review evaluates the efficacy of pre-expanded supraclavicular artery flaps based on a comprehensive analysis. In accordance with the Preferred Repo [...]

The implementation of modern technologies has transformed connectivity, information-sharing, and education, significantly influencing students' academic journeys. New technologies offer advantages and disadvantages, particularly impacting young students and leading to changes in habits and behaviors. While technology can improve learning efficiency through personalized approaches, excessive screen time can negatively affect communication and academic performance. Studies recommend limited screen time for children t [...]
