Lei 14.151/21 e o regime de teletrabalho às trabalhadoras gestantes durante a pandemia de covid-19: uma análise do conflito entre direito à saúde e o poder diretivo do empregador à luz da teoria dos direitos fundamentais / Law 14.151/21 and the telework regime for pregnant workers during the covid-19 pandemic: an analysis of the conflict between the right to health and the employer's directive power in light of the fundamental rights theory

Os direitos fundamentais são ferramentas cruciais para a efetivação e concretização do princípio da dignidade da pessoa humana no ordenamento jurídico. A Constituição Federal de 1988 traz os direitos e garantias fundamentais em um rol não taxativo e bastante extenso, que se mostra como reflexo do pluralismo ideológico que permeia o texto constitucional. Por promoverem a proteção constitucional aos mais diversos valores sociais, é bastante comum que ocorra, no caso concreto, conflitos entre os direitos fundamentais de diferentes titulares. Desde o ano de 2019, a pandemia de COVID-19 tem causado grandes impactos nos mais diversos setores no mundo. No Brasil, foi editada a Lei 14.151/21, que determina o afastamento das trabalhadoras gestantes do trabalho presencial em razão da pandemia. O presente trabalho se propõe a realizar um estudo acerca da teoria dos direitos fundamentais, que servirá de base para a análise do conteúdo da Lei 14.151/21 e seus impactos nas relações de trabalho, tendo-se como foco principal o embate entre o direito fundamental à saúde da gestante e o direito fundamental à livre iniciativa através do poder diretivo do empregador. Para tanto, usou-se, como referencial teórico, autores como Robert Alexy, Alexandre de Moraes, Perez Luño e Paulo Bonavides, entre outros

Growth and biomass production of prickly pear in the second cycle irrigated with treated domestic sewage

This study aimed to evaluate, in the second cycle, the growth and production of ‘Orelha-de-elefante Mexicana’ prickly pear (Opuntia sp.) under complementary irrigation with treated domestic sewage. The experiment was carried out in the Milagre Settlement, municipality of Apodi-RN, Brazil, from June 2016 to February 2017. Five treatments were evaluated, corresponding to four irrigation frequencies (2.3, 7.0, 14.0 and 21.0 days) to apply an effluent depth of 3.5 mm, and the control, rainfed cultivation (without irrigation). The experimental design was randomized blocks, with four replicates. After preliminary-primary treatment, the domestic sewage showed acceptable chemical and physical characteristics for fertigation under the conditions adopted in the prickly pear cultivation. 234 days after the 1st cut in the plants, the following morphometric characteristics were measured: plant height and length, width, perimeter, thickness and number of primary and secondary cladodes, and biomass accumulation. Complementary irrigation with treated domestic sewage effluent applied at intervals of 2.3, 7.0, 14.0 and 21.0 days allowed satisfactory growth and production of ‘Orelha-de-elefante Mexicana’ prickly pear; without irrigation, its development was substantially hampered during the dry period. Complementary irrigation with 3.5 mm of domestic sewage effluent applied at intervals of 2.3, 7.0 and 14.0 days led to highest growth and biomass accumulation in ‘Orelha-de-elefante Mexicana’ prickly pear

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

Potencial visual evocado por padrão reverso com tabuleiro de xadrez em gatos domésticos adultos

O potencial visual evocado por padrão reverso (PVE-PR) é um método objetivo, não invasivo e estabelecido para as investigações funcionais. Este trabalho teve como objetivo a obtenção de dados do PVE-PR com tabuleiro de xadrez em gatos domésticos adultos, além de verificar a influência de diferentes ângulos visuais sobre os picos de tempo implícito e amplitude das ondas N75 e P100. Foram utilizados 13 gatos adultos (2-4 anos de idade), de ambos os sexos. Cada animal foi posicionado 100cm de distância de um monitor de vídeo situado a 17,2º. O estímulo gerado para a formação dos PVEs foi uma onda "quadrada" com a frequência de 6 Hz, apresentados em cinco frequências espaciais (16', 32', 64', 130' e 260'de arco). Os valores médios dos tempos implícitos (ms) e amplitudes (µV) de P100 não foram diferentes estatisticamente e nem estavam correlacionados (r=0,067). Com a mudança de tamanho do ângulo de estímulo apresentado, os picos de tempo implícito e amplitude do P100 apresentaram uma discreta variação. Aos 32' de arco, a amplitude de P100 atingiu seu pico máximo, com 14,94±1,13µV (média±erro padrão da média). N75 não mostrou nenhuma variação de amplitude. Com 16' de arco, o tempo implícito de N75 diminuiu, não havendo correlação com os valores de amplitude (r=0,26). O ângulo visual que desencadeou um maior pico de amplitude e tempo implícito constante para P100, foi o de 32' de arco. Em gatos adultos, um PVE-PR pode ser obtido sem o uso de midriáticos e sedativos, com estímulos subtendidos entre ângulos grandes como 64' e pequenos como 16
