ABSTRACT A novel, unique, simple route was introduced to form a highly crystalline phase of lime (CaO) using by a precipitating agent. The structural parameters were ascertained by X‐ray diffraction (XRD), which offered an in‐depth understanding of the material's crystalline characteristics. The XRD...

Toxicity due to chemotherapy has been a major issue in cancer treatment and the existing risk measurements are mostly based on immune homeostasis parameters at baseline that are not capable of assessing changing physiological dynamics throughout the treatment. This paper presents a new machine learn...

Battery-powered electric tricycles, locally called “Easy Bikes”, have expanded rapidly in Bangladesh as a low-cost mobility option, particularly in secondary cities and peri-urban corridors. Despite their socio-economic importance, the sector operates largely outside formal technical standards, rais...

Sandwip Island, located at the Meghna River estuary in the Bay of Bengal, is highly vulnerable to cyclones, storm surges, tidal flooding, and saline intrusion. These hazards accelerate shoreline retreat and degrade freshwater aquifers creating a coupled system of geomorphic and hydrogeological risks...

Detection and classification of bone fractures in medical imaging greatly help doctors make accurate diagnoses and plan treatments more efficiently. Traditionally, people have depended a lot on manual methods for this, which take up too much time and often lead to mistakes from human oversight. In r...

An inverter is a device that transforms DC power into AC power. Inverters can be categorized into single-level inverters and multilevel inverters. This paper discusses two controlled strategies-equal step angle and sinusoidal switching angle-for a multilevel inverter, highlighting their effectivenes...

High distribution system losses remain a major obstacle to efficient electricity supply in developing countries. In Bangladesh, losses exceed 10% and include both technical losses (TLs), caused by conductor resistance, transformer inefficiencies, and reactive power flow, and non technical losses (NT...

Leather buffing dust (BD), a solid waste generated from the leather industry, was utilized as a raw material for synthesizing activated carbon (AC) through ZnCl 2 activation and pyrolysis. The main focus of this study was to prepare an adsorbent with low price and high efficiency to remove turbidity...

Concomitant coronary artery bypass surgery (CABG) in patients undergoing mitral valve replacement (MVR) has been shown to be an important risk factor for hospital mortality. We evaluated preoperative characteristics, postoperative complications, in-hospital mortality rate, and length of stay in hosp...
