1. Quando indicar uso de anticoagulante para um paciente com Fibrilação Atrial(FA)?
Quando a FA apresentar escore CHA2DS2-Vasc maior ou igual a 1, neste caso, pontuado pela hipertensão e pela idade, tem indicação de anticoagulação adequada. São utilizados medicamentos antagonistas da vitamina K, como o Warfarin ou algum dos novos ACO (NACO), classe de medicamentos de inibidores diretos do fator Xa, como a rivaroxabana, a ap

2. Selective formation of neodymium phosphate from iron-neodymium magnet waste
Abstract Neodymium-iron-boron alloy, Nd2Fe14B, is used as a material for magnets. Neodymium is one of the valuable and expensive rare earth elements and is often recovered to reduce costs and environmental impact. Recently, a method for recovering neodymium as neodymium phosphate from mixed solutions was reported. This method was very useful because the main

3. A review of systems biology research of anxiety disorders
The development of “omic” technologies and deep phenotyping may facilitate a systems biology approach to understanding anxiety disorders. Systems biology approaches incorporate data from multiple modalities (e.g., genomic, neuroimaging) with functional analyses (e.g., animal and tissue culture models) and mathematical modeling (e.g., machine learning) to

4. Reusable Heterogeneous SnO2/ZnO Catalyst for Biodiesel Production from Acidified/Acid Oils
A catalyst comprised of SnO2 impregnated on ZnO nanowires, which presented remarkable ability to catalyze fatty acid esterification/transesterification reactions, is reported. For optimization of reaction conditions, artificially acidified soybean oil with 10 wt.% oleic acid was used as a model feed. The optimized conditions were: 150 °C, 6 h, 5 g of oil, c

5. Microstructural and mechanical characterisation of the Simon Bolivar's iron bridge structure, 19th century, Arequipa, Peru
Abstract The microstructure of the main structural elements (Phoenix columns, transversal beams and tie-rods) of the Simón Bolivar iron bridge, located in Arequipa (Peru), was investigated. The bridge was supposedly designed by Gustave Eiffel and opened to the public in 1882. The characterisation revealed that the columns, beams and tie-rods are made of pud

6. Effect on Merlot red wine of fining agents mixture: application of the simplex centroid design
Abstract In the elaboration of young red wine, it is necessary to obtain a clear product with stable color. The clarity and stability can be obtained using fining agents. The objective of this study was to evaluate the combined effect of fining with pea protein isolate (PPI), bentonite, and polyvinylpyrrolidone (PVPP) on a red wine, using the experimental de

7. Optimization of sunflower oil bleaching parameters: using Response Surface Methodology (RSM)
Abstract Bleaching is an important part of the oil refining process, in which pigments, impurities, traces of metals, and oxidative-molecular components of oils are removed. In this regard, the optimization of bleaching conditions can be effective to increase oil quality. In this study, de-gummed and neutralized sunflower oil was bleached at 80, 90, 100, 110

10. Aplicação de processo adsortivo para dessulfurização de combustíveis utilizando fibra de coco como adsorvente
RESUMO A presença de compostos orgânicos contendo enxofre nos combustíveis é um dos contribuintes da poluição atmosférica, pois quando entram em combustão nos motores, emitem poluentes derivados do enxofre, como os óxidos (SOx), que afetam negativamente a saúde humana e o meio ambiente. A remoção do excesso de enxofre presente na gasolina pode se

12. EVALUATION OF DISTILLATION CURVES FOR BIO-OIL OBTAINED FROM THERMAL CRACKING OF WASTE COOKING OIL
ABSTRACT Bio-oil obtained from thermal cracking of waste cooking oil (WCO) is a complex mixture of different chemical compounds and, like crude oil, it is composed mainly of hydrocarbons. The large number of compounds in bio-oil leads to complex and expensive methods for its properties determination. In this study, the distillation curves were constructed fo
