With the growing significance of the circular economy (CE) agenda in the fashion industry and, consequently, in fashion design education, this work introduces the initial phase of a case study that aims to ascertain whether CE principles and sustainability are part of the curriculum and pedagogical approaches employed by educators in the Fashion Design Technician course (FDTC) (level 4, National Qualifications Framework—QNQ, and European Qualifications Framework—EQF). Additionally, it seeks to identify the methodologies, strategies, and educational activities used to address these themes. This research outlines the review of documentary sources that facilitated the definition of the study’s object and sample and describes the implementation of a questionnaire survey to forty educators teaching this course across various disciplines encompassing the three training components (sociocultural, scientific, and technological) in fifteen out of the sixteen Portuguese vocational schools, during the academic year 2023/24. This phase of the case study has led to the conclusion that while the technical course curriculum may not extensively cover CE and sustainability, these topics are integral components of most pedagogical practices among the surveyed teachers. The methodologies, strategies, and activities employed display a strong commitment to fostering sustainable practices, predominantly nurturing environmental awareness among students. Full article

The advent of immersive technologies, such as virtual reality (VR), augmented reality (AR), and mixed reality (MR), is transforming higher education by providing innovative and interactive learning experiences. This article addresses the imperative of integrating these technologies into higher education systems. The study explores the intersection of immersive technologies and pedagogical strategies, aiming to enhance the European Qualification Framework (EQF) by updating learning outcomes to reflect the competence required in the digital age. Through a comprehensive literature review, case studies, and expert consultations, we propose a set of educational design guidelines tailored for higher education institutions. These guidelines align immersive technology applications with EQF levels and descriptors, focusing on undergraduate and postgraduate education. Our findings highlight the potential of immersive learning to foster critical thinking, creativity, and practical skills, while also addressing challenges such as accessibility and faculty training. By providing actionable insights and recommendations, this paper contributes to the development of a robust framework for incorporating immersive technologies in higher education, ensuring that students are equipped with the necessary skills and knowledge to thrive in a rapidly evolving digital world.

In 2017, Europe implemented a ban on amalgam restorations for children aged <15 years and for pregnant/breastfeeding women, highlighting the need for alternative filling materials exhibiting less surface roughness and enhanced longevity. This in vitro study aimed to examine the surface roughness variations of five amalgam-replacement materials across three time points and using six finishing methods: (1) no finishing (control), (2) Arkansas burs, (3) diamond burs, (4) tungsten carbide burs, (5) SofLex discs in descending grit size, and (6) coarse SofLex discs combined with silicone polishing. We prepared 960 samples. Each material group, i.e., Cention Forte (CNF), DeltaFil (DLF), Ketac Universal (KTU), IonoStar Molar (ISM), and Equia Forte HT (EQF), comprised 60 samples (n = 10 per finishing method) created using standardized 3D-printed metal molds. Surface roughness (Sa) was measured immediately after finishing, after 30 days of storage in distilled water, and after thermocycling (5000 cycles) using a non-contact profilometer. The results indicate that conventional and hybrid glass-ionomer cements have smoother surfaces than high-viscosity GICs. The DLF and CNF groups exhibited stable outcomes. These findings underscore the importance of selecting appropriate finishing methods based on the restorative material to minimize surface roughness. Full article

Equiform geometry is considered an extension of other geometries. Furthermore, an equiform frame is a generalization of the Frenet frame.

Equiform geometry is considered an extension of other geometries. Furthermore, an equiform frame is a generalization of the Frenet frame. In this study, we begin by defining the term “equiform parameter (EQP)”, “equiform frame”, and “equiform formulas (EQF)” in regard to the Minkowski three-space. Second, we define spacelike normal curves (SPN) in Minkowski three-space and present a variety of descriptions of these curves with equiform spacelike (EQS) or equiform timelike (EQN) principal normals in Minkowski three-space. Third, we discuss the implications of these findings. Finally, an example is given to illustrate our theoretical results. Full article

This review article provides a concise overview of electron involvement in DNA radiation damage. The review begins with the various states of radiation-produced electrons: Secondary electrons (SE), low energy electrons (LEE), electrons at near zero kinetic energy in water (quasi-free electrons, (eqf)) electrons in the process of solvation in water (presolvated electrons, epre), and fully solvated electrons (eaq). A current summary of the structure of eaq, and its reactions with DNA-model systems is presented. Theoretical works on reduction potentials of DNA-bases were found to be in agreement with experiments. This review points out the proposed role of LEE-induced frank DNA-strand breaks in ion-beam irradiated DNA. The final section presents radiation-produced electron-mediated site-specific formation of oxidative neutral aminyl radicals from azidonucleosides and the evidence of radiosensitization provided by these aminyl radicals in azidonucleoside-incorporated breast cancer cells.
