Within distributed generation (DG), different types of technology are used to produce electricity, including photovoltaic and wind generation systems. However, their coupling in large quantities can cause power quality problems due to the stochasticity of the data in the distribution circuits; therefore, the main objective of this article is to analyze, through simulation, the impact of coupling microgeneration or distributed generation. The system used is the Zonhan 600 W/24 V DC wind turbine and 230 Wp polycrystalline solar panels, both known for their high efficiency. Meteorological data is obtained from an LSI LASTEM station equipped with a DNA121, DMA672.1 optoelectronic anemometer, and an ELOG305 data logger, which is coupled to an NI cRIO9022. The data is then entered into an OPAL5600 (Real-Time Digital Simulator). Simulink—DigSilent is loaded inside the Opal and experimentally verified using the Fluke 434 Power Quality Analyzer.

The energy demand data is taken from the monthly records of the higher education institution. According to the results, the impact of the DG system is less than 1
Fiber-cement composites are used in lightweight construction due to their favorable balance of mechanical and physical properties. This study investigates the influence of rice husk-derived cellulose microfibers on the performance of fiber-cement boards. Specimens were prepared with varying fiber concentrations (0.0, 3.0, 6.0, 9.0 and 12.0
Background: Third molar extraction is the most frequently performed surgical procedure in dentistry worldwide, yet its clinical management remains inconsistent. Despite abundant literature on individual aspects of third molar care, a comprehensive, integrated framework combining evidence-based indications, preoperative assessment, surgical technique selection and complication risk stratification is lacking in current practice. Objective: To critically synthesize current evidence on third molar management, with emphasis on extraction indications, classification systems, imaging selection, surgical technique, complication profiles, preventive strategies and the role of individualized risk stratification in clinical decision-making. Methods: A narrative review was conducted using PubMed/MEDLINE, Scopus and Google Scholar. Search terms included “third molar,” “impacted third molar,” “wisdom tooth extraction,” “inferior alveolar nerve injury,” “dry socket,” “CBCT,” “coronectomy,” and “platelet-rich fibrin,” among others. Priority was given to systematic reviews, randomized controlled trials and high-impact narrative reviews published within the last five years; landmark studies were included when historically relevant. Literature was organized into thematic domains and synthesized qualitatively. Results: Postoperative complications occur in approximately 10% of cases, with impaction depth, patient age, root proximity to the inferior alveolar canal and surgical duration as the primary predictors. Prophylactic extraction of asymptomatic, disease-free third molars lacks sufficient high-quality evidence to support or refute the practice. Traditional classification systems show limited predictive accuracy for surgical difficulty and must be complemented by selective cone-beam computed tomography imaging in high-risk cases. Coronectomy substantially reduces inferior alveolar and lingual nerve injury rates compared to complete extraction in anatomically complex cases. Minimally invasive strategies, including piezosurgery and platelet-rich fibrin socket management, demonstrate consistent benefits for postoperative morbidity reduction. Conclusion: Evidence-based third molar management requires individualized preoperative assessment, selective use of advanced imaging, technique selection matched to anatomical complexity and operator experience and structured complication prevention protocols. Routine prophylactic extraction should give way to a risk-stratified, patient-centered approach that prioritizes informed decision-making and timely multidisciplinary collaboration.
En este artículo se analizan las variaciones en los tipos de decisiones adoptadas por traductores profesionales y traductores en formación durante el proceso de posedición de un texto de divulgación científica. Las decisiones se clasificaron en decisiones de rutina y estereotipadas (caracterizadas por un menor esfuerzo cognitivo) y decisiones razonadas y construidas (más conscientes y deliberadas). Con base en esta clasificación, se realizó un estudio de carácter positivo, exploratorio y de alcance descriptivo. La recolección de datos se realizó mediante el uso de Translog II, verbalizaciones retrospectivas (método R+RP) y un cuestionario sobre toma de decisiones, aplicados a tres traductores profesionales y tres traductores en formación. Los resultados evidenciaron variaciones en los tipos de decisiones adoptadas por los participantes. Los traductores profesionales mostraron un desempeño más adecuado y razonado en sus procesos decisionales en comparación con los traductores en formación, lo que sugiere que la experiencia influye significativamente en la toma de decisiones.
The objective of this presentation is to evaluate a resistance and polish retention of 3D- printed and Milled Zirconia by an exhaustive analysis of a contemporary literature review. The information collected by different authors enables us to contrast 3D- printed permanent restoration and milled zirconia highlighting their advantages, limitations and implications for clinical practice. After analyzing both 3D printing and milled zirconia, each material carries meaningful implications for modern dentistry. 3D printing stands out for its cost efficiency and streamlined production, while milled zirconia continues to earn its place through exceptional durability and resistance to wear. Mechanically, the two materials are more comparable than one might expect, yet their real-world performance tells a different story, particularly when surface longevity is put to the test over time. For now, milled zirconia remains the more dependable choice for long-term restorations. That said, dismissing 3D printing would be shortsighted. The technology is evolving rapidly and closing the gap in surface properties and longevity is well within reach. When that happens, the benefits for both patients and dental practices, in terms of accessibility and cost, could decrease substantially.
