From surface to deep sea: A depth-resolved vertical profile of microplastics in the Canary Basin

Microplastic (MP) contamination of the open ocean is well documented, yet the vertical structuring of MPs and the role of water masses in shaping deep-water inventories remain poorly resolved along the eastern boundary of the North Atlantic Subtropical Gyre. Here we present a hig...

Comparative Analysis of KAN and MLP Models for Feature Selection Based on Network Weights and SHAP Explanations

Breast cancer is one of the most prevalent cancers among women, and its early detection plays a crucial role in improving treatment outcomes. Machine learning has been widely adopted to support breast cancer prediction by developing predictive models from medical data. However, n...

A 3D meshless electromechanical model incorporating electrode inertia for accurate prediction of resonance characteristics in disk-type MEMS resonators

In this study, wave propagation in disk-type piezoelectric resonators is investigated by extending the polynomial modeling approach to incorporate electrode inertia. For sufficiently thin metallic electrodes, their elastic stiffness is neglected and only their mass contribution i...

Development and investigation of a NiO/ZnO@PPy-modified glassy carbon electrode for electrochemical sensing of metronidazole in environmental samples: Experimental and DFT studies

Metronidazole (MTZ) is widely prescribed as an antimicrobial drug, and its extensive use in animal farming has led to its accumulation in the environment, posing significant risks to human health and the environment. In this study, nickel and zinc oxide (NiO/ZnO) composite materi...

Assessment of selected heavy metals pollution (chromium, lead, and cadmium) in edible vegetables and agricultural soils influenced by tannery activities in the Amhara Region, Ethiopia

Industrial heavy metal pollution in agricultural soils threatens food safety and human health. This study assessed chromium (Cr), lead (Pb), and cadmium (Cd) concentrations in soils and vegetables collected from four tannery sites in Ethiopia's Amhara region. Soil and vegetable s...

Biological Activities and In Silico Molecular Docking of an Aqueous Extract of Nigella sativa L. Seeds: A Focus on Antioxidant, Cytotoxic, and Diuretic Effects

Background: Nigella sativa L. is a medicinal plant widely recognized for its diverse pharmacological properties. This study aimed to evaluate the antioxidant, diuretic, and cytotoxic effects of an aqueous seed extract and its effects on selected biochemical parameters in rats. Th...

Iliopsoas abscess in crohn’s disease: systematic review of case reports and case series

Transmural inflammation is a hallmark of Crohn’s disease (CD), a chronic inflammatory bowel disease that exposes patients to serious consequences such as fistulas and abscesses. Iliopsoas abscess (IPA) is an uncommon but potentially fatal penetrating (extra-luminal) complication...

Brain metastases as a manifestation of late relapse in high-grade serous ovarian cancer: Diagnostic and therapeutic challenges

Brain metastases from ovarian cancer are uncommon, with an estimated incidence of 1%-3%, and are usually associated with advanced-stage disease and prolonged survival. We report the case of a 55-year-old woman diagnosed with metastatic high-grade serous ovarian carcinoma presenti...

From soil disruption to biodegradation: A comprehensive review of microplastic effects and microbial breakdown mechanisms in terrestrial ecosystems

Abstract Microplastics (MPs) are pervasive in the environment, posing a significant global environmental challenge. Agricultural ecosystems are particularly vulnerable to MP contamination due to the extensive use of plastics in farming practices. This issue is further aggravated...

Phenology-Informed Crop Type Mapping in Semi-Arid Morocco Using Sentinel-2 NDVI Time Series: A Machine Learning Approach with Temporal Sensitivity Analysis

Accurate crop mapping is essential for food security and water resource management in semi-arid North Africa. This study evaluated four machine learning algorithms for crop classification using Sentinel-2 NDVI time series in the Al Haouz region, Morocco with a time series of 12 d...

Exploring the relationship between a structured, embodied analogy and students’ conceptual understanding in science

This study presents an innovative educational analogy grounded in a structured, embodied, and associative framework designed to support students’ conceptual understanding in science education. Focusing on secondary school students in Morocco, the study explores the relationship b...

Cost of quality management in the agrifood sector: a systematic review of indicators and implementation outcomes

Purpose This study systematically reviews empirical research on cost of quality (CoQ) management in the agrifood sector, where CoQ-related research remains fragmented and under-theorized. It synthesizes evidence on CoQ measurement indicators and the organizational outcomes of CoQ...
