Impactos da COVID-19 na saúde mental entre universitários da saúde

Resumo O objetivo deste estudo foi investigar os impactos da COVID-19 na saúde mental entre estudantes universitários de Ciências da Saúde. Trata-se de um estudo transversal e quantitativo, cuja amostra foi constituída por 618 estudantes universitários da área da saúde. Os sintomas depressivos foram avaliados por meio do Patient Health Questionnaire 9 (PHQ-9). A prevalência dos sintomas depressivos foi estimada...

How sulfate content and soil depth affect the adsorption/desorption of selenate...

ABSTRACT Sorption of selenate (SeO 4 2- ) and selenite (SeO 3 2- ) is poorly understood in Brazilian agroecosystems, especially in soils from agricultural areas containing different contents of competing anions, such as sulfate (SO 4 2- ). This study aimed to assess the sorption behavior of selenate and selenite at different soil layers of a tropical soil treated with different rates of agricultural gypsum (thu...

Assessment of Trace Element Contents in Soils and Water from Cerrado Wetlands, ...

ABSTRACT In the Brazilian Cerrado biome, there are wetlands locally known as “Veredas”, which are swampy plains between hills and rivers. Since the 1970’s, the Cerrado biome has been gradually converted to livestock, crop, or forestry production. Until now, very few studies were conducted to evaluate the baseline contents of trace elements in Cerrado wetland soils. Due to their position in the landscape (bottom...

Bipedal and unipedal stance in Brazilian football 7-a-side athletes with cerebr...

ABSTRACT To compare postural control between Football 7-a-side players with cerebral palsy (CP) and active non-athletes without neurologic impairments, 28 individuals (15 to 35 years old) were selected and divided into the Non-Athletes Group (NAG), consisting of 14 individuals without neurologic or musculoskeletal injury; and the CP Group (CPG), composed of 14 athletes from the regional football team. A force p...

Soil management and ionic strength on selenite retention in oxidic soils

ABSTRACT Sorption of selenium (Se) on soils may be influenced by factors that are changed though agricultural practices usually performed for crop production, such as soil pH, competing anion and organic matter contents, among others. This study aimed to evaluate the influence of soil management and ionic strength (IS) on Se retention in Brazilian soils, which is important to predict Se availability in both sys...

Selenium behavior in the soil environment and its implication for human health

ABSTRACT Selenium (Se) is an important element that was discovered in 1817, and since the 1960s, it has been regarded as an essential micronutrient for both animals and humans, playing among other functions a relevant role in the antioxidant system of mammals. Inadequate blood Se levels in the human body is a well-known concern in many parts of the world. This malnutrition problem is often due to Se-poor diet, ...

Fitorremediação de solos contaminados com arsênio (As) utilizando braquiária

Conduziu-se este trabalho, com o objetivo de avaliar o potencial fitoextrator de arsênio (As) da Brachiaria decumbens Stapf., cultivada em casa de vegetação, utilizando-se seis solos: Latossolo Amarelo Distrófico (LAd), Latossolo Vermelho Distrófico (LVd), Neossolo Flúvico (RU), Neossolo Quartzarênico (RQ), Gleissolo Háplico (GX) e Gleissolo Melânico (GM). O As foi adicionado aos solos na forma de arsenato de s...

Caracterização de subproduto da indústria de alumínio e seu uso na retenção de ...

The present work aimed to characterize an aluminum industry by-product in natura (L.A. nat) and after phosphate and thermal pretreatments; evaluate the adsorption/desorption capacity of Cd and Pb by this L.A. nat form and after the aforementioned pretreatments, comparing them with an in natura iron mining by-product (L.F. nat). The L.A. nat presented a high pH as well as a high Na concentration and also an oxid...

Subproduto da indústria de alumínio como amenizante de solos contaminados com c...

A poluição do solo com elementos-traço tem sido motivo de preocupação nos últimos anos, o que justifica melhor conhecimento da disponibilidade desses elementos no ambiente, visando amenizar seus efeitos em áreas contaminadas. Este trabalho teve como objetivo avaliar o desempenho de um subproduto da indústria de alumínio como amenizante de solos contaminados com Cd e Pb. Foram utilizados um Neossolo Quartzarênic...
