Documentations of patterns in traditional knowledge is of paramount importance if we are to fully understand the relationship between people and their local environment. Investigations of medicinal plant use also contribute to discoveries of new drugs, by highlighting taxa which might have bioactivity of interest, and preservation of traditional knowledge, by identifying species important to local communities and describing how traditional knowledge is transmitted to future generations. Increasingly methods borrowed from ecology and community phylogenetics are used to understand patterns in medicinal plant use and inform bioprospecting. These methods are best applied to information-rich, large data sets, yet despite the growth in ethnobotanical research, data are scattered. This thesis exploits traditional knowledge documented in literature and herbaria, using newly compiled data for Brazil to explore patterns in medicinal plant use, in documentation of ethnomedicinal species, pharmacological investigation and distribution of plant use. Comparison of data from literature and herbarium sources, based on 1400 use reports of medicinal use of species of the family Leguminosae, showed herbaria to be a valuable source of data for ethnobotanical research. Despite the lower proportion of herbarium records (compared to literature records) with information on therapeutic application, modes of use and parts used, herbarium records validated data in the literature and added new information. These and additional data were used to demonstrate Ewe, a web-based database developed here, with tools to store and visualise ethnobotanical data. Research questions relating to pharmacological investigation of Brazilian plants used in traditional medicine, and to the spatial distribution of traditional knowledge were addressed using these and other data sets compiled for this study. Phylogenetic methods were used to explore the diversity of Leguminosae species with medicinal use, revealing phylogenetic diversity of species used despite of lineages rich in species with medicinal use (hot nodes) accounting for 45% of the species used in local medicine. Hot nodes are better characterized pharmacologically. Finally, the spatial distribution of traditional knowledge in Brazil was investigated, using a novel generic-level phylogeny for the Brazilian flora and species-level herbarium data for Angiosperms in Brazil with medicinal uses. According to taxonomic and phylogenetic measures of beta diversity, spatial heterogeneity in medicinal plant use was identified, highlighting local adaptation of medicinal floras despite the preference for some plant groups revealed by clustering in deep nodes.

General Medicine - Abstract
Este artigo tem por objetivo analisar a constituição da reexistência por meio da fala feminina negra inscrita na formação discursiva midiática. Para tanto, ancora-se nas formulações teóricas da Análise do Discurso (AD) de vertente francesa, nas contribuições foucaultianas e em diálogo com os estudos étnico-raciais descoloniais. Na análise, recorremos a três enunciados coletados de um portal brasileiro de notícias on-line, em que uma mulher negra, mãe e empregada doméstica é entrevistada durante a pandemia de covid-19. Os resultados apontam para uma fala feminina negra entre a desigualdade, preconceito, discriminação e que encontra lugares de reexistência negra possível no enfrentamento às opressões. Concluímos que o discurso midiático inserido em formações discursivas reatualiza as memórias acerca dos modos de viver e morrer de grupos étnico-raciais na contemporaneidade.

The Red List Index (RLI) measures change in the aggregate extinction risk of species. It is a key indicator for tracking progress toward nine of the Aichi and many proposed post‐2020 Global Biodiversity Framework Targets. Here, we consider two formulations of the RLI used for reporting biodiversity trends at national scales. Disaggregated global RLIs measure changing national contributions to global extinction risk and are currently based on five taxonomic groups, while national RLIs measure changing national extinction risk and are based on taxonomic groups assessed multiple times in country. For 74% of nations, the disaggregated global RLI is currently based on three or fewer taxonomic groups. Meanwhile, national RLIs from selected pilot countries Finland, South Africa, and Brazil are computed from twelve, eight, and nine taxonomic groups, respectively. The national RLI and the disaggregated global RLI measure different aspects of biodiversity, in that the former detects national trends in populations of species for which each country is responsible while the latter provides standardized comparisons of nations' contributions to the global extinction risk of the same species groups. As governments commit to the post‐2020 Global Biodiversity Framework, we encourage them to monitor a standard set of taxonomic groups representing different biomes using both RLI formulations to ensure effective target tracking and accurate feedback on their conservation investments.

Sensors, in general, are a pillar of contemporary technology. Their applications, types and models are used in several fields. Thus, it becomes indispensable development of sensors and wireless communication methods between devices, even as equipment control. This work proposed a system to detect liquefied petroleum gas (LPG) in a mixture with air, using an experimental apparatus organized by the gas sensor element, a temperature controller and an Arduino board equipped with a Zigbee wireless data transmitter. The work involved the area of chemistry and computing to reach aims, from development of SnO2 sensor element to instrumentation. The text presents the preparation of colloidal suspension, film deposition and thermal treatment, gas mixture system assembly and sensor element heating. Also, was described the microcontroller couplings for data transmission via Zigbee devices, the design and construction of the voltage divider circuit, as well as the characterization of the oxide film and sensor measurements in a gas and LPG atmosphere. A microcomputer, using a program written in Python, stored the data, conditioned by a microcontroller, received through the Zigbee wireless network. In addition to the technical results for the gas sensor developed with sensitivity within the limits of flammability, the work allows to conclude that the involvement of related areas can results in the development complete work from sensor preparation to instrumentation. Os sensores são um dos pilares da tecnologia contemporânea. Suas aplicações são inúmeras para diferentes campos. Assim, torna-se indispensável o desenvolvimento de sensores e métodos de comunicação entre dispositivos, bem como equipamentos de controle. Este trabalho propôs um sistema para detecção em fase gasosa de gás liquefeito de petróleo (GLP) em mistura com ar, utilizando um aparato experimental formado por elemento sensor de gás, controlador de temperatura e uma placa Arduino equipada com um transmissor de dados sem fio Zigbee. O trabalho envolveu a área de química e computação para atingir desde o desenvolvimento do elemento sensor a base de SnO2 até a instrumentação, apresentando assim a preparação da suspensão coloidal, deposição e tratamento térmico do filme, a montagem do sistema de mistura de gases e sistema de aquecimento do elemento sensor, os acoplamentos do microcontrolador para transmissão de dados através de dispositivos Zigbee, a elaboração e construção do circuito eletrônico, bem como a caracterização do filme de óxido e as medidas de sensor em atmosfera de mistura gasosa envolvendo ar e GLP. Um microcomputador, utilizando um programa escrito em linguagem Python, armazenou os dados, condicionados por um microcontrolador, recebidos por meio de rede sem fio Zigbee. Além dos resultados técnicos para o sensor desenvolvido com sensibilidade dentro dos limites de inflamabilidade da mistura ar e GLP, o trabalho permite concluir que o envolvimento de áreas relacionadas permite o desenvolvimento de trabalhos amplos envolvendo desde a elaboração até a instrumentação de sensor.

MODEL theory - Abstract
In this work, the stages of construction of a nuclear-type transformer were presented in detail and how electrical measurements can be used to extract relevant parameters from it. The physical theory for the model of a real transformer has been briefly described. Theoretically, it was concluded that this can be treated as an ideal transformer plus external impedances. In the experimental analyses, it was possible to obtain the resistances and reactances of the coils and the core and with this estimate the transformer efficiency. [ABSTRACT FROM AUTHOR]

This work aims to understand and discuss how the cisgender man lives his cultural identity in the present time, named as postmodern. To discuss this process, the research used the Brazilian law of installation of baby changing facilities in male bathrooms, as means to analyze the contemporary context of male identity formation and new ways of exercising masculinity, seeking a new horizon of possibilities for this process. Using as a theorical basis for this work, the "liquid society" concept, from "liquidity" concept by Zygmunt Bauman, is used to explain how it influences the construction process of male identity. In order to do this, a literature review was carried out. This indicated that there is an ongoing process of reviewing the concept of masculinity and the baby changing room in the men's bathroom, by breaking with sexist and patriarchal logic, suggests the possibility of a new male ways of living.
