Influência do fotoperíodo no parasitismo de Cleruchoides noackae em ovos de Thaumastocoris peregrinus.

Espécies de Eucalyptus são importantes para a economia brasileira e os plantios ocupam aproximadamente 5,5 milhões de hectares. O percevejo bronzeado do eucalipto Thaumastocoris peregrinusé uma praga exótica da cultura. A microvespa parasitoide Cleruchoides noackae (Hymenoptera: Mymaridae) é a principal alternativa de controle utilizada. O objetivo deste trabalho foi avaliar a influência do fotoperíodo no parasitismo de C. noackae, em ovos de T. peregrinus. Na montagem do experimento foram utilizados frascos de poliestireno contendo dez ovos de T. peregrinuspara cada casal de C. noackae. Os parasitoides foram alimentados com uma solução de mel a 50% fornecidos em tiras de papel filtro. Os frascos contendo os parasitoides foram mantidos a 24 °C ± 2 °C, 70% ± 10% UR e fotoperíodo de 12L:12D, por 24 horas. Após este período, os casais foram removidos e os ovos colocados em câmaras climatizadas tipo BOD a 24 °C ± 2 °C, 70% ± 10% UR, nos seguintes tratamentos de fotoperíodo: 24L:0D, 0L:24D, 12L:12D, 16L:8D e 8L:16D. Após a emergência dos parasitoides, foram montados casais com a geração F1, os quais foram mantidos nos mesmos tratamentos e condições descritas. O período de desenvolvimento e a razão sexual da geração parental e a taxa de parasitismo da geração F1 foram avaliados. O período de desenvolvimento de C. noackae foi menor no regime de fotoperíodo 8L:16D e semelhante nos demais avaliados. O regime de fotoperíodo não afetou a razão sexual do parasitoide. O fotoperíodo afetou a taxa de parasitismo de C. noackae, sendo superior para insetos mantidos por 16 horas na presença de luz e 8 horas no escuro. A definição do melhor regime de fotoperíodo poderá otimizar a produção de C. noackae em laboratório

Anthropometry for children's clothing: difficulties and limitations

Children's wear lacks an anthropometric study to better fit clothes on the body of the child, providing greater comfort for users. Initially, this thesis project in fashion design intended to measure Portuguese children between the ages of 2 to 10 years, enrolled in primary schools in the region of Minho in Portugal. During the data gathering, held in the months of June, July, October and November 2016, about 600 children were scanned and measured using a 3D body scanner. The purpose of this paper is to report the difficulties and limitations experienced during data collection of the anthropometric study and the adjustments that were needed, as well as discuss some of the data collected.This work is supported by FEDER funds through the Competitive Factors Operational Program (COMPETE) POCI-01-0145-FEDER-007136 and by national funds through Portuguese Foundation for Science and Technology (FCT), under the project UID/CTM/000264.info:eu-repo/semantics/publishedVersio

EPIDEMIOLOGICAL PROFILE OF ARBOVIROSIS IN THE STATE OF MARANHÃO: DENGUE FROM 2010 TO 2020

Dengue is an arbovirus considered a growing problem in relation to public health worldwide. With this, the objective of this work is to describe, in a retrospective and analytical way, the epidemiological profile and the spatial distribution of dengue cases in the state of Maranhão between the years 2010 to 2020. This quantitative and retrospective study used secondary data provided by the State Department of Health (SES-MA) of confirmed and notified cases of the disease in a time frame between 2010 and 2020. In addition, geoprocessing techniques were also used to spatialize the data. The results indicate that there were oscillations in relation to confirmed and reported cases throughout this period in the state, especially in the north and southwest regions. Thus, Maranhão reveals a critical state in relation to the occurrence of the disease, which is possibly associated with environmental factors, infrastructure and lack of public policies related to basic sanitation.info:eu-repo/semantics/publishedVersio

Distinctive effects of allochthonous and autochthonous organic matter on CDOM spectra in a tropical lake

Despite the increasing understanding about differences in carbon cycling between temperate and tropical freshwater systems, our knowledge on the importance of organic matter (OM) pools on light absorption properties in tropical lakes is very scarce. We performed a factorial mesocosm experiment in a tropical lake (Minas Gerais, Brazil) to evaluate the effects of increased concentrations of al-lochthonous and autochthonous OM, and differences in light availability on the light absorption characteristics of chromophoric dissolved organic matter (CDOM). Autochthonous OM deriving from phytoplankton (similar to Chl a) was stimulated by addition of nutrients, while OM from degradation of terrestrial leaves increased allochthonous OM, and neutral shading was used to manipulate light availability. Effects of the additions and shading on DOC, Chl a, nutrients, total suspended solid concentrations (TSM) and spectral CDOM absorption were monitored every 3 days. CDOM quality was characterized by spectral indices (S250-450, S275-295, S350-450, S-R and SUVA(254)). Effects of carbon sources and shading on the spectral CDOM absorption was investigated through principal component (PCA) and redundancy (RDA) analyses. The two different OM sources affected CDOM quality very differently and shading had minor effects on OM levels, but significant effects on OM quality, especially in combination with nutrient additions. Spectral indices (S250-450 and S-R) were mostly affected by allochthonous OM addition. The PCA showed that enrichment by allochthonous carbon had a strong effect on the CDOM spectra in the range between 300 and 400 nm, while the increase in autochthonous carbon increased absorption at wavelengths below 350 nm. Our study shows that small inputs of allochthonous OM can have large effects on the spectral light absorption compared to large production of autochthonous OM, with important implications for carbon cycling in tropical lakes.Peer reviewe

Biomimetic Design at Stuttgart's Conceptual Pavilions and their Aspects of Sustainability

This article aims to elucidate the aspects of Biomimetics, discussing its most current methodology (Biomimicry DesignLens); As well as to make known the biomimetic examples of the conceptual pavilions developed by the University of Stuttgart, created with the purpose of testing new space systems through constructive modules that allow a high degree of adaptability and performance due to the geometric differentiation of its components, using for this, innovative manufacturing computational processes to test, simulate and apply, including through the use of articulated robotic arms. It is observed that the inspiration for the configuration of these modules is based on references of the nature, collaborating so that the use of this methodology is translated as a viable solution to promote a sustainable design, since the solutions of the natural world, either through shapes or processes, are always based on resource efficiency

Linking shifts in bacterial community with changes in dissolved organic matter pool in a tropical lake

Bacterioplankton communities have a pivotal role in the global carbon cycle. Still the interaction between microbial community and dissolved organic matter (DOM) in freshwater ecosystems remains poorly understood. Here, we report results from a 12-day mesocosm study performed in the epilimnion of a tropical lake, in which inorganic nutrients and allochthonous DOM were supplemented under full light and shading. Although the production of autochthonous DOM triggered by nutrient addition was the dominant driver of changes in bacterial community structure, temporal covariations between DOM optical proxies and bacterial community structure revealed a strong influence of community shifts on DOM fate. Community shifts were coupled to a successional stepwise alteration of the DOM pool, with different fractions being selectively consumed by specific taxa Typical freshwater clades as Limnohabitans and Sporichthyaceae were associated with consumption of low molecular weight carbon, whereas Gammaproteobacteria and Flavobacteria utilized higher molecular weight carbon, indicating differences in DOM preference among Glades. Importantly. Verrucomicrobiaceae were important in the turnover of freshly produced autochthonous DOM, ultimately affecting light availability and dissolved organic carbon concentrations. Our findings suggest that taxonomically defined bacterial assemblages play definite roles when influencing DOM fate, either by changing specific fractions of the DOM pool or by regulating light availability and DOC levels.

Comportamentos autolesivos, percepção de suporte familiar e sintomas ansiosos e depressivos em adolescentes Pernambucanos

Comportamentos autolesivos na adolescência se tornaram um problema de saúde pública mundial. Frequentemente, esses comportamentos compõem o quadro sintomático de doenças psiquiátricas, sendo conceitualizados como estratégias disfuncionais de regulação emocional. Diante disso, este estudo investiga a relação entre comportamentos autolesivos, percepção de suporte familiar e sintomas ansiosos e depressivos em adolescentes da rede estadual de ensino do Recife, assim como estima a prevalência do fenômeno (n=501). Também buscou-se estimar a prevalência do fenômeno e sua relação com variáveis sociodemográficas. Os instrumentos utilizados foram o Protocolo Health Behaviour in School-Aged Children, aSpence Children's Anxiety Scalee o Inventário de Depressão Infantil, todos adaptados ao português brasileiro. Foram realizadas análises da consistência interna, qui quadrado, teste t, correlação e descritivas. Os resultados apontaram prevalência de 31,3% para comportamentos autolesivos. Adolescentes do sexo feminino apresentaram 2,26 vezes mais chance de engajar na prática de comportamentos autolesivos. Verificou-se diferenças significativas entre participantes que se autolesionavam e aqueles que não se autolesionavam no tangente à percepção de sintomas depressivos, sintomas ansiosos e suporte familiar. Nossos achados enfatizam aimportância dos vínculos familiares no combate aos comportamentos autolesivos. Assim, esperamos contribuir para a construção de estratégias preventivas contra comportamentos de risco, ansiedade e depressão.ABSTRACT: Self-injurious behaviors in adolescence have become a public health problem worldwide. Often these behaviors are symptoms of psychiatric diseases, conceptualized as dysfunctional strategies of emotional regulation. Therefore, this study investigates the relation between self-injurious behaviors, family support perception and anxiety and depressive symptoms within adolescents from the state education network in Recife. It also estimates the prevalence of the phenomenon (n=501).Another goal was to estimate the prevalence of the phenomenon and its relation with sociodemographic variables. The instruments used were the Health Behavior in School-Aged Children Protocol, the Spence Children's Anxiety Scale and the Children’s Depression Inventory, all adapted to Brazilian Portuguese. Internal consistency, chi-square, t-test, correlation and descriptive analyzes were performed. The results showed a prevalence of 31.3% for self-injurious behaviors, with female adolescents being 2.26 times more likely to engage in self-injurious behaviors. There were significant differences between participants who engaged in self-injurious behaviors and those who did not due to their perceptions of depressive symptoms, anxious symptoms and family support. Our findings emphasize the importance of family bonds in combating self-injurious behaviors. Thus, we hope to contribute to the creation of preventive strategies against risk behaviors, anxiety and depression.info:eu-repo/semantics/publishedVersio
