Piper carpunya, commonly known as guaviduca, is a perennial aromatic shrub that forms part of the botanical and cultural heritage of tropical regions in South America, where it has been widely used in traditional medicine. This study aimed to conduct a comprehensive physicochemical characterization of the essential oil extracted from this species. The research was carried out at the Chemistry and Bromatology Laboratories of the Amazonian State University, using fresh leaves collected from subtropical regions of Ecuador. The essential oil was obtained through steam distillation, and its chemical composition was determined by gas chromatography (GC), revealing a complex mixture of monoterpenes and oxygenated derivatives. Among these, 1,8-cineole (12.5 %) and cis-sabinene hydrate acetate (14.1 %) were the most prominent, both known for their antimicrobial, anti-inflammatory, and antioxidant properties. The oil’s balanced chemical profile and high oxidative stability make it suitable for therapeutic, cosmetic, and pharmaceutical applications. The results confirm its potential as a functional ingredient in various industries.

The aim of this study is to investigate the acute effect of Nordic Hamstring Exercise (NHE) applied to sub-elite football players on Hamstring (H) muscle strength values (maximum value and Total Work) and Muscle Stifness (Semimembrenous and Biceps Femoris) values. 43 sub-elite male (16.50 ± 0.505) football players participated in the study voluntarily. Participants' H muscle strength values were determined with N3 brand device; Muscle Stifness values were determined with myoton brand device. The normalcy analysis of the data acquired in the study was performed with the Kolmogrov Smirnov test. Participants' pre-test post-test comparisons were determined with the Wilcoxon Signed Ranks test. Based on the statistical analysis, it was identified that NHE utilized to sub-elite football players increased the Total Work (right-left leg) value of the H muscle strength values acutely and the stiffness value of the Biceps Femoris muscle (right-left leg) significantly in the post-test. It may be argued that NHE applied to football players acutely increases H muscle strength and BF muscle stiffness value, provides performance efficiency and is a protective strategy against injuries.

El Anuario de la Facultad de Arquitectura, en conjunto con la «Muestra Estudiantil», son proyectos llevados a cabo con la misión de recopilar y exponer el trabajo realizado por las y los estudiantes de la Facultad de Arquitectura (FA). Platicamos con Jorge Andreas, coordinador editorial de esta publicación, sobre la edición más reciente y sobre sus experiencias en esta iniciativa de la comunidad estudiantil.

La Coordinación de Vinculación de Egresados de la Facultad de Arquitectura (VEFA)  busca fortalecer la conexión entre los egresados y los estudiantes, y generar así un ciclo de retribución y apoyo mutuo.

This text explores ballroom and voguing as both artistic and political practices that resignify urban space and at the same time transform hostile environments into spaces of safety and belonging. Focusing its analysis on the context of Mexico City, the article examines their social, cultural, and aesthetic impact, as well as the way in which they contribute to enhance community cohesion.
