This manuscript presents an innovative control strategy for the Hybrid Excitation Permanent Magnet Synchronous Motor (HEPMSM) designed for electric vehicle (EV) applications. The strategy combines Maximum Torque Point Tracking (MTPT) and Maximum Torque Per Ampere (MTPA) techniques to track the ideal torque-speed profile, ensuring maximum torque at low speeds for starting and climbing, and high power at higher speeds for cruising. A novel unidirectional excitation current method is proposed to replace traditional bidirectional field current control, eliminating the risk of permanent magnet demagnetization, reducing copper losses, and increasing efficiency.

Eco-friendly cellulose/TiO₂-hydroxyapatite films for biomedical applications.

Int J Biol Macromol

March 2025

University of Coimbra, CEMMPRE, ARISE, Department of Mechanical Engineering, Rua Luís Reis Santos, 3030-788 Coimbra, Portugal.

In this work cellulose/TiO flexible films coated with hydroxyapatite, aiming the development of electro-active orthopaedic scaffolds, were produced, applying sustainable procedures. The TiO nanoparticles were incorporated into the cellulose, extracted from potato peel, and the films were fabricated by the casting method. The hydroxyapatite, synthesized by the sol-gel technique, was electrodeposited onto the cellulose/TiO films, at room temperature.

Article Synopsis
  • Alzheimer's disease (AD) is primarily influenced by genetic factors, particularly the APOE ɛ4 allele and certain variants of the TREM2 and ABCA7 genes.
  • The study assessed the relationship between specific genetic variants and sporadic AD in 222 Tunisian patients compared to 99 healthy controls.
  • Results indicated a significant association of the TREM2 rs2234253 (p.T96K) variant and the APOE ɛ4 allele with increased AD risk, while ABCA7 variants showed no significant link, highlighting the need for further research with larger populations.

Background And Objectives: Hereditary spastic paraplegias (HSPs) are inherited neurodegenerative disorders, and their classification is based on inheritance mode, allelic variants, and clinical presentation. Despite global occurrence, research, especially in the Middle East and North Africa (MENA) regions, is lacking, underscoring the need for further investigation. The objective of this study was to improve the regions' clinical practice and public health, and this study aims to gather data on HSP prevalence, pathogenic variants, and patient characteristics in MENA countries.

Laboratory of Aquatic Systems: Marine and Continental Environments (AQUAMAR), Department of Biology, Faculty of Sciences, Ibn Zohr University, Agadir, Morocco.

Plastic pollution in marine ecosystems is a growing concern, yet the degradation behavior of different plastic types and their interactions with microbial communities remain poorly understood. This study investigated the degradation kinetics and microbial colonization of four widely used plastic materials, surgical masks (most made of PP), PET bottles, PS foam, and PP cups, over 40 days of seawater exposure in the Central Atlantic of Morocco. Mass loss measurement revealed distinct degradation patterns, with PS foam showing the highest mass loss (13 %), followed by PET bottles (5 %), likely due to environmental stressors that promote mechanical fragmentation.

The analysis of animal responses to immunization is fundamental to vaccine development, enabling the evaluation of immune responses and the elucidation of key mechanisms underlying protective immunity. Such insights are essential for advancing vaccines through clinical trial stages and regulatory approval. Furthermore, understanding the molecular signatures of approved vaccines not only deepens our knowledge of their function but also guides the rational design and improvement of future vaccines.

Introduction: This study explores the intersection of physical exercise, masculinity, and aging in older men, examining how these elements shape identity and bodily experiences. Aging is often framed through deficit-based narratives that emphasize decline; however, this research seeks to reframe aging as a process of adaptation and opportunity. By investigating how physical activity contributes to identity reconstruction, this study aims to provide insights into the broader social and structural factors influencing older men's engagement in exercise.

Residual contamination by intravenous antineoplastic drugs on hospital surfaces remains a critical concern, as highlighted by numerous studies. This study presents a novel, rapid and highly sensitive analytical method for quantifying a wide range of antineoplastic drugs and detecting other potentially harmful molecules on wiped surfaces. Utilizing hydrophilic interaction liquid chromatography (HILIC) coupled with high-resolution spectrometry, the method combines the quantification of eight commonly used antineoplastic drugs: 5-fluorouracil, ifosfamide, cyclophosphamide, gemcitabine, doxorubicin, methotrexate, epirubicin and irinotecan, with the identification of unknown compounds offering a comprehensive solution for monitoring hospital surface contamination.
