Publicación Acceso abierto Comportamiento de la adhesión de fibras de plátano y coco tratadas y no tratadas químicamente embebidas en matrices termoplásticas y termofijas(Universidad de Córdoba, 2023-02-21) Barrera Fajardo, Ismael José; Unfried Silgado, JimyIn this work have been evaluated adhesion of coconut and banana fibers on several treatment conditions and using two polymeric matrix. Fibers were extracted from banana pseudostem and coconut esocarp, which were dried at a temperature of 40°C and 90°C, determining how the drying temperature influences the mechanical properties. Choosing 40°C for banana fibers and 90°C for coconut fibers as the best temperature, these sets of fibers were treated with alkali and various properties were compared using characterization techniques such as tension tests, scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FTIR). Simply dried and INFORME FINAL DEL TRABAJO DE INVESTIGACIÓN CONVENCIONAL Comité de Acreditación y Currículo Facultad de Ingenierías por una universidad con calidad, moderna e incluyente Carrera 6ª. No. 76-103 Montería NIT. 891080031-3 - Teléfono: 7860300 - 7860920 www.unicordoba.edu.co mercerized fibers were embedded in polymeric matrices to determine the influence of fiber treatment on adhesion with polylactic acid (PLA) and unsaturated polyester resin and to obtain manufacturing parameters to improve the properties of natural fiber-reinforced composites using 3D printing and resin transfer molding (RTM) processes. Using the PullOut fiber extraction test, it was possible to prove that mercerizing improves the interfacial adhesion with the abovementioned matrices.Publicación Acceso abierto Factores que influyen en la adherencia al tratamiento de quimioterapia en mujeres con cáncer de mama: una revisión integrativa de la literatura(2022-09-01) Ortiz López, Angie Katherine; Peña de Hoyos, Silvia Patricia; Valencia Jiménez, Nydia NinaBreast cancer is typified as the most common among women worldwide, likewise, is considered a public health problem. Among the common treatments for breast cancer chemotherapy stands out. The objective of this research was document the scientific evidence about the factors that influence adherence to chemotherapy treatment in women with breast cancer. This study consisted of an integrative review of the literature, with a descriptive and retrospective scope. A search of the information was carried out in da tabases such as; Proquest, Scielo, Scopus, Embase, Science Direct, BVS, Lilacs, Pubmed, Medline and the Repository of the University of Córdoba. A total of 11,701 publications were collected. Applying all exclusion and inclusion criteria, 20 articles were selected, of these, 19 publications are in Spanish and 1 in Portuguese. According to the selected literature, we can classify factors related to treatment adherence into 3 types or classes; I). Sociodemographic factors, including religious beliefs, age, s ex and socioeconomic status. II). Social or family factors: The most common factors are the presence of a stable partner and family support. III). Treatmentrelated factors: Factors such as adverse effects and type of treatment stand out. In addition, the quality of life of the breast cancer patient is influenced by 4 main factors; Physical condition and functioning, Treatmentrelated illness and symptoms, Psychological functioning and social functioning.
