Caracterização da qualidade da água superficial de três corpos hídricos rurais do Distrito Federal.

A água é um recurso natural intensamente utilizado e essencial à manutenção da vida. Dentre os principais contribuintes para o comprometimento da qualidade da água pode-se destacar os efluentes (domésticos, rurais, industriais), despejados diretamente nos corpos hídricos, e os deflúvios superficiais de origem urbana e agrícola. A agricultura maior usuária de água doce a nível mundial contribui para as preocupações a respeito das implicações globais da qualidade da água. O setor agrícola é o maior consumidor de água. No Brasil, quase metade da água consumida destinase a agricultura irrigada. Uma vez que os corpos hídricos são os principais fornecedores de água para a população e agricultura, torna-se necessário identificar as principais fontes de poluição e obter dados para efetiva gestão dos mananciais. Estudos de monitoramento são importantes para o acúmulo de informações sobre a quantidade e a qualidade dos corpos d?água. Diante do exposto o objetivo do presente trabalho foi caracterizar e comparar a qualidade da água superficial em três corpos hídricos inseridos em ambientes rurais do DF. O monitoramento dos três corpos hídricos demonstrou que a água está adequada a utilização para fins de irrigação, conforme a Resolução CONAMA 357/05, apresentando valores satisfatórios para maioria dos parâmetros físico-químicos e microbiológicos. Abstract: Water is a natural resource used intensively and essential for sustaining life. Among the main contributors to the impairment of water quality can highlight effluents (domestic, rural, industrial), dumped directly into water bodies, and surface runoffs from urban and agricultural. Agriculture largest user of freshwater worldwide contributes to concerns about the global implications of water quality. The agricultural sector is the largest consumer of water. In Brazil, almost half of the water consumed is intended for agricultural irrigation. Once the water bodies are the major suppliers of water to the population and agriculture, it is necessary to identify the main sources of pollution and to obtain data for effective management of watersheds. Monitoring studies are important for the accumulation of information on the quantity and quality of water bodies. Given the above the purpose of this study was to characterize and compare the quality of surface water in three water bodies in situations in rural FD. The monitoring of the three water bodies showed that the water is suitable for use for irrigation, according to CONAMA Resolution 357/05, satisfactory values for most of the physical, chemical and microbiological

An investigation of mental imagery in bipolar disorder: Exploring "the mind's eye".

OBJECTIVES: Mental imagery abnormalities occur across psychopathologies and are hypothesized to drive emotional difficulties in bipolar disorder (BD). A comprehensive assessment of mental imagery in BD is lacking. We aimed to test whether (i) mental imagery abnormalities (abnormalities in cognitive stages and subjective domains) occur in BD relative to non-clinical controls; and (ii) to determine the specificity of any abnormalities in BD relative to depression and anxiety disorders. METHODS: Participants included 54 subjects in the BD group (depressed/euthymic; n=27 in each subgroup), subjects with unipolar depression (n=26), subjects with anxiety disorders (n=25), and non-clinical controls (n=27) matched for age, gender, ethnicity, education, and premorbid IQ. Experimental tasks assessed cognitive (non-emotional) measures of mental imagery (cognitive stages). Questionnaires, experimental tasks, and a phenomenological interview assessed subjective domains including spontaneous imagery use, interpretation bias, and emotional mental imagery. RESULTS: (i) Compared to non-clinical controls, the BD combined group reported a greater impact of intrusive prospective imagery in daily life, more vivid and "real" negative images (prospective imagery task), and higher self-involvement (picture-word task). The BD combined group showed no clear abnormalities in cognitive stages of mental imagery. (ii) When depressed individuals with BD were compared to the depressed or anxious clinical control groups, no significant differences remained-across all groups, imagery differences were associated with affective lability and anxiety. CONCLUSIONS: Compared to non-clinical controls, BD is characterized by abnormalities in aspects of emotional mental imagery within the context of otherwise normal cognitive aspects. When matched for depression and anxiety, these abnormalities are not specific to BD-rather, imagery may reflect a transdiagnostic marker of emotional psychopathology

Estimativas da interação genótipo x ambiente (GA) em progênies de sorgo forrageiro desenvolvidas pelo IPA - Instituto Agronômico de Pernambuco.

Resumo: Em face da instabilidade climática do semiárido brasileiro, notadamente quanto à escassez e a distribuição errática das chuvas, o sorgo forrageiro que apresenta características de xerofilia detém a vantagem sobre a maioria das plantas forrageiras recomendadas para a região como suporte a pecuária, no atendimento de volumosos no período estival do ano. Foi utilizada a metodologia AMMI - ?Additive Main Effects and Multiplicative Interaction? (Análise de Efeitos Aditivos Principais e Interação Multiplicativa) que investiga a interação genótipo ambiente, e tem sido usada por vários autores e em diversas culturas. O objetivo deste trabalho foi avaliar o comportamento de 30 genótipos de sorgo forrageiro testados em seis ambientes do semi-árido de Pernambuco e de Alagoas usando a técnica AMMI visando recomendação. Os genótipos foram desenvolvidos pelo IPA a partir do método sequencial de pedigree, oriundos de cruzamentos e de autofecundações sucessivas até gerações avançadas. Através da análise infere-se que os genótipos G14, G22, G27 e G5 podem ser considerados estáveis e os genótipos G16 e G7 foram os que mais contribuíram com a interação GA

Mindcraft, a mobile mental health monitoring platform for children and young people: development and acceptability pilot study

BACKGROUND: Children and young people's mental health is a growing public health concern, which is further exacerbated by the COVID-19 pandemic. Mobile health apps, particularly those using passive smartphone sensor data, present an opportunity to address this issue and support mental well-being. OBJECTIVE: This study aimed to develop and evaluate a mobile mental health platform for children and young people, Mindcraft, which integrates passive sensor data monitoring with active self-reported updates through an engaging user interface to monitor their well-being. METHODS: A user-centered design approach was used to develop Mindcraft, incorporating feedback from potential users. User acceptance testing was conducted with a group of 8 young people aged 15-17 years, followed by a pilot test with 39 secondary school students aged 14-18 years, which was conducted for a 2-week period. RESULTS: Mindcraft showed encouraging user engagement and retention. Users reported that they found the app to be a friendly tool helping them to increase their emotional awareness and gain a better understanding of themselves. Over 90% of users (36/39, 92.5%) answered all active data questions on the days they used the app. Passive data collection facilitated the gathering of a broader range of well-being metrics over time, with minimal user intervention. CONCLUSIONS: The Mindcraft app has shown promising results in monitoring mental health symptoms and promoting user engagement among children and young people during its development and initial testing. The app's user-centered design, the focus on privacy and transparency, and a combination of active and passive data collection strategies have all contributed to its efficacy and receptiveness among the target demographic. By continuing to refine and expand the app, the Mindcraft platform has the potential to contribute meaningfully to the field of mental health care for young people
