Caracterização Físico-química e Clones de Batata-doce de Polpa Alaranjada nas Condições de Palmas-TO

Resumo: o objetivo deste artigo foi obter informações a respeito da produtividade e características físicas químicas da batata-doce de polpa alaranjada visando o consumo humano e animal e sua potencialidade para utilização na indústria alimentícia. Após análise estatística dos resultados obtidos (produtividade, danos mínimos causados por insetos, matéria-seca (massa seca), cinzas, sólidos solúveis e amido), os clones BD# 09 e do BD#35 foram os mais produtivos e com os melhores valores de danos mínimos, o clone BD#02 é o mais produtivo em termo de matéria-seca, o BD#36 destacou-se com o maior percentual de amido com 47,62%. Palavras-chave: Batata-doce. Características ficisoquímicas. Amido

Implementação de Algoritmos para os Cálculos das Novas Definições de Potência através do uso da Plataforma LabVIEW / Implementation of Algorithms for the Calculations of New Power Definitions through the use of LabVIEW Platform

Dentro da grande área de Sistemas Elétricos de Potência, o indicador Fator de Potência (FP) se torna de grande importância na medida em que consumidores industriais pagam multas quando este indicador fica abaixo de 0,92, de acordo com a norma vigente nº 414/2010 da ANEEL (Agência Nacional de Energia Elétrica). Buscando meios para medir corretamente este indicador, existem esforços nacionais e internacionais voltados para a interpretação correta de situações reais compreendendo tensões e correntes elétricas com distorções harmônicas, assunto este de grande importância quando se tem uma energia com perda de qualidade. Nesta situação real, percebe-se que o FP diminui, aumentando a possibilidade de cobranças de multas por parte das concessionárias de energia. Buscando aprimorar os conhecimentos neste sentido, este artigo apresenta um software na plataforma LabVIEW capaz de calcular e comparar as diferentes formulações internacionais relatadas na literatura

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.
