1. COVID-19: laboratory diagnosis for clinicians. An updating article
ABSTRACT COVID-19 (coronavirus disease 2019) is an infectious disease caused by the new coronavirus associated with severe acute respiratory syndrome 2 (SARS-CoV-2). Coronaviridae comprises a large family, of which at least seven members are known to cause respiratory diseases in humans. Coronaviruses have the ability to infect virtually all major groups of

4. Aircraft spacing for continuous descent approach in a terminal area based on required time of arrival at a metering fix.
Guiding arriving flights through congested terminal airspace has always been a challenge. As traffic builds up, controllers must often move traffic away from the airport until they can bring those flights in for landing, causing inefficiencies. A widespread implementation of Continuous Descent Approach (CDA) would result in significant reductions in environm

6. Desenvolvimento de sistemas de liberação para a administração tópica passiva e iontoforética do minoxidil no tratamento da alopecia androgênica / Development of delivery systems for the topical passive and iontophoretic administration of minoxidil for the androgenic alopecia treatment
Given the hypothesis that polymeric microparticles can penetrate the skin barrier along the transfollicular route, and based on the evidence that iontophoresis is a method that can direct the delivery of drugs to the hair follicles, this work aimed to study the in vitro skin permeation of minoxidil sulfate (MXS), a drug used to treat androgenic alopecia, bot

7. Barreiras à entrada e habilitação em licitação: o artigo 37, inciso XXI, da constituição federal visto sob as perspectivas do direito administrativo e do direito antitruste
Trata-se de trabalho sobre o estabelecimento de barreiras à entrada em procedimentos de licitação governamental. O texto inicia-se com uma descrição da literatura especializada acerca do conceito de barreiras à entrada. Discute-se a inexistência de definição pacífica do termo e a necessidade de identificação de pressupostos conceituais para o uso

10. Propriedade intelectual com ênfase em trade secrets: criptologia e performance econômica
This work presents a theoretical approach on intellectual property with emphasis in trade secrets as entry barriers. Progress in cryptology in the field of the mathematics can be added to the theoretical efforts developed in microeconomics in industrial organization. In this context, cryptology is rescued historically and its main functions are presented in

11. Aspectos da estrutura, funcionamento e manejo da reserva particular do patrimônio natural "Ecoparque de Una": região cacaueira do Sul da Bahia, Brasil. / Aspects of the structure, functioning and management of the "Ecoparque de Una" private nature reserve: cocoa production region at southern Bahia, Brazil.
The cocoa production region of southern Bahia harbors the largest fragments of Atlantic Forest in the State of Bahia, possessing a high frequency of endemics and species richness, and being presently considered a priority area for biodiversity conservation. Nevertheless, the process of implementing Conservation Units in the region is not keeping up with the

12. Estudo da relaxação magnetica e fluxo retido em Niobio supercondutor : efeitos da superficie
We present in this work a study of the surface influence in magnetic relaxation of superconducting niobium. We also discuss the relevance of the sample surface condition on magnetic flux trapping associated with the occurrence of a paramagnetic frozen state. Magnetization measurements were made, using a SQUID magnetometer, on a single-crystal Nb bar, for dif
