Effects of Khaya ivorensis and Hevea brasiliensis Wood Sawdust on the Cultivation and Nutritional Composition of Pleurotus ostreatus (Jacaum ex. Fr. Kummar)

This study was conducted to examine the effect of hardwood (Khaya ivorensis) and softwood (Hevea brasiliensis) on the proximate and nutritional composition of (Pleurotus ostreatus) (Jacaum ex. Fr. Kummar) with the aim of comparing its proximate and nutritional composition on the...

Kepler: A Deep Learning Pipeline for Transit-Based Exoplanet Candidate Identification in TESS Sectors 1 through 97

TESS has produced light curves for hundreds of millions of stars, more than traditional tools like Box Least Squares can feasibly vet alone. We present Kepler, a CNNtransformer hybrid trained to detect the periodic brightness dips caused by transiting planets. Using TESS Sectors...

Designing Epistemic Partnerships with Generative AI: A Four-Stage Model of Student Engagement in Scientific Argumentation

Abstract This study examined how a design-based learning environment supported first-year undergraduates’ ( N = 31) epistemic engagement with generative AI in a science argumentation course. A two-year design-based research (DBR) study was conducted across two cycles (2024: n = 1...

Association between hemoglobin A1c levels and coronary flow reserve in angina with nonobstructive coronary arteries: a retrospective observational study

Abstract Background Hemoglobin A1c (HbA1c) measures chronic glycemic levels, and its elevation is associated with vascular endothelial dysfunction and microcirculatory impairment, contributing to increased cardiovascular risk. In the assessment of angina with nonobstructive coron...

Electrospun Nanofibrous Architectures for Food Packaging: A Review of Pore Engineering, Permeability Control, and Sustainability

Abstract Fresh food spoils rapidly when packaging cannot balance gas exchange with moisture and microbial barriers. Conventional plastic films generally fall short of these combined demands. This review examines electrospun nanofibrous architectures (NFAs) as next-generation sust...

A Multi-Layer Digital Twin Framework for a Confectionery Preparation Cell with AI-Assisted SCADA 4.0 Monitoring

This paper presents a semester-long engineering project that develops a multi-layer Digital Twin for the chocolate-bar preparation stage, a bakery producer in Monterrey, Mexico. In the current process, operators manually open shipping boxes, separate multi-bar packages, peel indi...

ASSESSMENT OF SELECTED HEAVY METAL CONTAMINATION, MODIFIED DEGREE OF CONTAMINATION AROUND LEAD ZINC MINE IN THE ENYIGBA, SOUTHEASTERN NIGERIA.

This paper focuses on heavy metal (Pb, Zn, Cu, Cd and As) contamination, modified degree of contamination in the soils of Enyigba, southeastern Nigeria. Pollution by these metals was examined using several calculation methods: modified degree of contamination and geoaccumulation...

Perceived Environment and Socioeconomic Impact of Quarrying Activities on Residents in Abeokuta, Nigeria

Quarrying is an important economic activity that supplies construction materials and creates employment opportunities. However, its environmental and socioeconomic consequences on nearby communities remain a growing concern in many developing countries. This study assessed the pe...

Effect of distal screw number on axial deformation and fragment-specific stability in AO/OTA 2R3 C2.1 distal radius fractures

PURPOSE: To investigate the biomechanical influence of distal screw number in palmar plate fixation of unstable intra-articular distal radius fractures with radiodorsal metaphyseal comminution. METHODS: Nine matched pairs of cryopreserved human radii were prepared using a standar...

Temporalities of destiny: Agency, relationality and divorce among women in Istanbul1

Abstract This article draws on the life stories of divorcing or divorced women living in Istanbul. By attending to my interlocutors’ transformations over time, in relation to others and divine power, it examines the complex workings of destiny and the idea of imtihan (test from G...

Proteome-wide interaction study of fatty acids and mortality in the UK Biobank

The heterogeneity in associations between circulating fatty acids (FA) and mortality remained underexplored. Proteomics can profile the human physiological status. This study aimed to estimate interactions between FA and proteins in relation to mortality. We randomly divided 30,1...

Correlation and Principal Component Analysis on Growth, Yield and Weed Parameters of Kenaf (Hibiscus cannabinus L.) in Sudan Savanna, Nigeria

This paper aims to show the effects of correlation and principal component analysis on growth, yield and weed parameters of Kenaf (Hibiscus cannabinus L.) in the Sudan Savanna, Nigeria. Kenaf has been used as a major source of fibres, paper, and other materials for many years. Th...

NUMERICAL SIMULATION OF HYDROMAGNETIZED BOUNDARY LAYER FLOW EQUATION WITH VISCOUS DISSIPATION EFFECT ON A PLATE UNDER VARIABLE TEMPERATURE

With variable temperature and viscous dissipation, this paper considers a classical problem of an MHD boundary layer flow over a rectangular plate in a uniform stream of fluid. By using similarity transformation, the governing nonlinear PDEs have been transformed into a set of OD...

Natural Killer Cell Phenotypic Changes and Activating Receptor Loss Posttrauma

BACKGROUND: Trauma induces significant physiological changes that can lead to substantial morbidity and mortality. Many of these changes alter immune homeostasis, which underlies seemingly disparate syndromes of systemic inflammation and global immune suppression, the causes of w...

Why Large Language Models Cannot Be Certified for Safety-Critical Systems

Large language models (LLMs) are moving rapidly into domains governed by functional-safety certification: aviation, road vehicles, medicine, and critical infrastructure. Certification regimes such as IEC 61508, DO-178C, and ISO 26262 combine system-level risk targets with process...

A Conceptual Framework to Integrate Research Programs on Self-Regulation in Education

Abstract Self-regulation (SR) has emerged as a pivotal construct in educational research, yet its diverse theoretical accounts often lack comprehensive integration. This paper addresses this by proposing an integrative conceptual framework that consolidates four core research tra...

DESIGN AND ANALYSIS OF LEG GUARD OF TWO-WHEELER FOR OPTIMIZATION OF WEIGHT AND STRENGTH

This study presents the design, explicit dynamic analysis, and material optimization of a diamond-shaped two-wheeler leg guard. A three-dimensional leg guard model was developed in CATIA V5 and analyzed in ANSYS 19.0 Explicit Dynamics under an impact condition against a fixed con...

Environmental Management Practices, Sustainable Architecture and Environmental Sustainability in Faith-Based Institutions in Nigeria

Faith-based institutions (FBIs) are increasingly recognized as strategic partners in promoting environmental sustainability because of their extensive physical infrastructure, moral authority, and community influence. Despite this potential, empirical evidence on how environmenta...

Associations between lifestyle factors and 2.5-year clinical outcomes differ by time since multiple sclerosis diagnosis

BACKGROUND: Healthy lifestyle factors are associated with better health outcomes in people with multiple sclerosis (pwMS). Whether these associations differ according to time since diagnosis remains unclear. Understanding this may inform optimal timing for lifestyle modification....
