Interpretable prediction of polymer material viscosity using machine learning models incorporating shear rate, salinity, concentration, and temperature effects

Abstract Viscosity is a fundamental property of polymer materials and solutions that strongly influences their flow behavior, processing, and performance in various industrial and engineering applications. Polymer materials and polymer solutions are vital components in many indus...

Comparative evaluation of ZnCl₂, KOH, and H₃PO₄ activated rice husk–neem leaf adsorbents for phenol adsorption

In the present study, the adsorption capacity of Rice Husk and Neem Leaf Powder (RHNL) activated using three chemical agents, ZnCl₂, KOH and H₃PO₄ with a 1:3-chemical to biomass ratio has been investigated to make biomass-derived activated adsorbents for phenol removal. Adsorptio...

Replacement of wheat bran with dried leftover food improves performance and carcass traits of grass hay-fed sheep

The high cost and limited availability of conventional feedstuffs need the exploration of sustainable and cost-effective alternatives. This study aimed to investigate the effects of wheat bran replacement with dried leftover food on feed intake, diet digestibility, growth perform...

Seismic vulnerability and sustainable retrofit strategies for traditional masonry heritage buildings in Oman

Traditional masonry buildings constitute an important part of Oman’s architectural heritage; however, their seismic performance has received limited systematic attention despite the country’s exposure to regional and local seismic hazards. This study presents a qualitative assess...

Tailoring the Mechanical and Acoustic Resonance of Ramie‐Blended Woven Epoxy Composites via Plasma and Alkaline Surface Modifications

ABSTRACT Natural fiber composites require a balance between reinforcement architecture and fiber–matrix interactions for favorable mechanical and vibroacoustic performance. This study examined the effects of weave architecture (plain, twill, satin) and surface modification, plasm...

Endovascular management of tuberculosis-related hemoptysis after thoracic endovascular aortic repair: anatomical characterization and embolization strategy

Abstract Background This study characterized the anatomical features of aberrant bronchial artery supply in patients with tuberculosis-related hemoptysis after thoracic endovascular aortic repair (TEVAR). It analyzed the technical challenges and strategies of bronchial artery emb...

Total intestinal atresia challenges the limits of neonatal surgery and healthcare equity in resource limited settings

Total intestinal atresia (TIA) is an exceptionally rare and severe form of neonatal intestinal obstruction, characterized by near-complete absence of functional bowel. Unlike more common types of intestinal atresia, which are amenable to surgical correction, TIA represents a fund...

Inappropriate stress ulcer prophylaxis and associated factors in critically ill patients in Addis Ababa, Ethiopia: a multicenter prospective observational study

Abstract Several consensus guidelines provide evidence-based recommendations for appropriate stress ulcer prophylaxis (SUP) use in critically ill patients. However, inappropriate prophylactic use remains common globally. A critical knowledge gap exists regarding SUP prescribing p...

Magnitude of precancerous cervical lesions in a fragile and conflict-affected setting: the case of Tigray region, Ethiopia

Cervical cancer remains a major public health concern, ranking as the fourth leading cause of cancer-related deaths among women globally and the second in Ethiopia. Limited access to routine screening, exacerbated by the Tigray war (November 2020–November 2022), has contributed t...

Health-related quality of life inequalities among patients with T2D in armed-conflict affected populations in Tigray, Northern Ethiopia

War causes tragic loss of life, destruction, and long-lasting quality-of-life distress in armed-conflict-affected populations. After conflict emerged between the federal government of Ethiopia and the Tigray regional government, the destruction of healthcare facilities and the bl...

Experimental investigation on the dynamic characteristics of expansive soil stabilized with polyvinyl alcohol–amended red mud

Black cotton soil (BCS) exhibits severe swell–shrink behaviour and poor resistance to cyclic loading, which limits their suitability for pavement subgrade and foundation applications. This study investigates the static and dynamic characteristics of expansive soil stabilized usin...

Genome-wide association study reveals putative genetic determinants of longitudinal immune responses to avian influenza and Newcastle disease in chickens

Abstract Background Avian Influenza virus (AIV) and Newcastle disease virus (NDV) are highly contagious immunosuppressive pathogens that cause high mortality rates and economic losses in the global poultry industry. Although vaccination to enhance the host antibody response remai...

Investigation of runoff and sediment transport processes in the hillslope headwaters of northern Ethiopia

Soil erosion and sediment transport pose significant threats to soil fertility, agricultural productivity, and reservoir sustainability in the Ethiopian highlands. This study investigated rainfall-runoff and sediment transport processes on the steep hillslope of the Midmar waters...

Building the toolkit to address malaria resurgence and radical cure of vivax malaria in Ethiopia: a meeting report

Abstract Ethiopia has experienced a substantial resurgence in malaria in recent years, with increasing case numbers and a growing contribution of Plasmodium vivax in several regions. At the same time, new evidence supporting improved radical cure strategies, including high-dose p...
