    Guia de boas práticas para departamento hospitalar e ambulatorial de oftalmologia
    (Universidade Federal de São Paulo (UNIFESP), 2016-12-21) Traverso, Maria Rossana Almeida [UNIFESP]; Rodrigues, Eduardo Buchele [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    This project was conceived in order to develop a good practice guide directed to the Department of Ophthalmology, which aims to facilitate the access to the good practice information that involve all procedures used in hospitals and clinics, correlating them with the current regulations. Sectors of the Department of Ophthalmology were considered, focusing on procedures regulated by Rules of the Federal, State and / or Municipal to then critically analyze and interpret the regulatory rules, consisting of laws, decrees, resolutions, guidelines and ordinances relevant to the department of ophthalmology and medical staff involved. Regulated procedures were described by preparing the Good Practice Guide for Hospital and Clinical Department of Ophthalmology and distributed in 8 chapters, which correspond to different categories of procedures adopted in the hospital and clinical department of ophthalmology. At a later stage, through the analysis of the Good Practice Guide for Hospital and Clinical Department of Ophthalmology, it was elaborated a checklist to be filled by doctors and/or professionals working in the hospital and / or clinical Department of Ophthalmology as a tool to help them in the control of the compliance with applicable rules. Evaluating the activities carried out in hospitals and clinical ophthalmology departments, correlating them with regulatory issues and good practice, a total of 17 Resolutions, 6 Ordinances, 2 Laws, 1 Decree, 1 Procedure, 1 Script, 1 Informative and 3 guides were identified, which were used as a reference for obtaining the information necessary for the preparation of the Good Practice Guide for Hospital and Clinical Department of Ophthalmology. Through the guide to good practice for hospital and clinical department of ophthalmology, the access to information necessary to ensure the quality and safety of services becomes easier.

    Reprocessability of PHB in extrusion: ATR-FTIR, tensile tests and thermal studies
    (Assoc Brasil Polimeros, 2017) Rivas, Leonardo Fabio; Casarin, Suzan Aline; Nepomuceno, Neymara Cavalcante; Alencar, Marie Isabele; Marcondes Agnelli, Jose Augusto; de Medeiros, Eliton Souto; Wanderley Neto, Alcides de Oliveira; de Oliveira, Mauricio Pinheiro [UNIFESP]; de Medeiros, Antonio Marcos; Ferreira e Santos, Amelia Severino
    Mechanical recycling of biodegradable plastics has to be encouraged, since the consumption of energy and raw materials can be reduced towards a sustainable development in plastics materials. In this study, the evolution of thermal and mechanical properties, as well as structural changes of poly(hydroxybutyrate) (PHB) up to three extrusion cycles were investigated. Results indicated a significant reduction in mechanical properties already at the second extrusion cycle, with a reduction above 50% in the third cycle. An increase in the crystallinity index was observed due to chemicrystallization process during degradation by chain scission. On the other hand, significant changes in the chemical structure or in thermal stability of PHB cannot be detected by Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analyses (TGA), respectively.
