Abstract: Considering that the relative attitude between the subsystems of space solar power station has the characteristic of periodic continuous change, the adjustment strategy of space large-span parallel cable mechanism is studied. Taking OMEGA (Orb-shape Membrane Energy Gathering Array) type space solar power station as the research object, the motion relationship between subsystems is analyzed. The kinematic analysis of the cable mechanism is carried out, and the variation rule of cable length is obtained. With the minimum variance of cable force as the optimization objective, the smoothness of cable force variation and the lightweight of cable as the design criteria, the optimal installation position of cable and the optimal adjustment strategy of cable mechanism are optimized. Through simulation analysis, the parallel cable mechanism proposed in this paper changes smoothly, which is suitable for the adjustment strategy of the relative attitude of the space solar power station subsystem.

Abstract: Micro gas sensors are integral to the automotive industry, particularly for monitoring the behavior of rarefied gases. The occurrence of inhomogeneous temperature gradients across microchannels can initiate gas flow, a principle that can be effectively utilized to develop micro gas sensors for automotive applications. This manuscript presents a novel microchannel design that incorporates quadrilateral sections with distinct temperature profiles. The characteristics of gas flow within this microchannel have been simulated numerically through the Direct Simulation Monte Carlo (DSMC) method, a sophisticated approach for such analyses. Subsequently, an optimization study is conducted to characterize the gas pumping properties of the microchannel. The results demonstrate that gas preferentially moves from a quadrilateral with lower temperature to one with higher temperature. The validity of this gas flow within the microchannel is confirmed. Notably, the gas flow velocity peaks at a Knudsen number of 3. This condition corresponds to a transitional flow regime, indicating that the microchannel’s gas pumping capability is most robust during this phase. Furthermore, it is observed that an increase in the quadrilateral aspect ratio leads to a reduction in gas flow velocity. These results can be applied to design micro gas sensors for various industry fields..

Goed beleid: tijd voor ‘regels beleidsdiscipline’
Je kon erop wachten: na jaren royaal spenderen uit de rijksbegroting klinkt nu overal in Den Haag weer de roep om meer zicht op doelmatigheid. En terecht: anders dan vaak wordt gedacht, is het snel uitgeven van meer geld niet hetzelfde als het voeren van goed beleid. In aanvulling op de regels budgetdiscipline hebben we daarom regels beleidsdiscipline nodig. Dat scheelt nog geld ook. In deze column legt de auteur dat ‘tongue in cheek’ uit.

Introdução: A degeneração macular relacionada à idade (DMRI) e o edema macular diabético (EMD) são condições retinianas graves que frequentemente causam perda significativa da visão. Ambas estão associadas à formação anormal de vasos sanguíneos na retina, um processo mediado pelo fator de crescimento endotelial vascular (VEGF). As terapias anti-VEGF têm revolucionado o tratamento dessas doenças ao inibir a neovascularização patológica, levando a melhorias na visão e na qualidade de vida dos pacientes. Este artigo avalia a eficácia e segurança dessas terapias, explora os avanços recentes em formulações e métodos de administração, e destaca as lacunas na pesquisa, como a variabilidade na resposta ao tratamento e os efeitos a longo prazo. O objetivo é aprimorar as abordagens terapêuticas e os resultados clínicos para os pacientes. Metodologia: Esta revisão sistemática avalia a eficácia e segurança das terapias anti-VEGF para doenças retinianas, como DMRI e EMD. O estudo analisa melhorias na visão e qualidade de vida dos pacientes, avanços nas terapias e efeitos a longo prazo. A pesquisa foi realizada em bases, incluindo artigos em português e inglês, publicados entre 2011 e 2024, que discutem esses tratamentos. Resultado: As terapias anti-VEGF são eficazes no tratamento de DMRI e EMD, melhorando a visão e reduzindo o edema macular ao bloquear o VEGF, que causa vasos sanguíneos anômalos na retina. Embora seguras, podem ter efeitos adversos como inflamação e aumento da pressão intraocular, necessitando de monitoramento. A personalização do tratamento é essencial para maximizar benefícios e minimizar riscos. Futuras pesquisas estão focadas em combinar anti-VEGF com outros tratamentos, desenvolver formulações de liberação prolongada e explorar terapias genéticas para aprimorar e potencialmente curar essas condições. Conclusão: As terapias anti-VEGF são eficazes para DMRI e EMD, melhorando a visão e reduzindo o edema macular. Embora geralmente seguras, devem ser monitoradas devido a possíveis efeitos adversos. Personalizar o tratamento conforme as características individuais do paciente é crucial. Futuras pesquisas devem buscar novas abordagens combinadas e agentes com melhor segurança e eficácia, além de explorar combinações com outras terapias para um manejo mais eficaz.

Influence of layup design on frictional wear and mechanical properties of carbon fiber reinforced epoxy resin
Authors: Wang Pengxiang , Zhao Wei 
Published: September 2024

The service life of carbon fiber reinforced epoxy (cf/ep) composites is determined by their wear and mechanical properties. Previous studies have often neglected the angle between the direction of friction and the direction of fiber alignment.In this study, cf/ep composites were made under orthogonal lamination and hot pressing conditions. The study simulated cross friction and three-point bending experiments to examine the impact of lamination order and ratio on tribological and mechanical properties. The results show that the friction coefficient is influenced by 66.7% due to the layup order, while the wear rate is affected by 33.3%.Furthermore, the study found an inverse relationship between the layup ratio and the friction coefficient.Additionally, there is a correlation between the angle of the fiber arrangement and the rate of transfer film formation. The rate of transfer film formation increases as the angle made by the load in the multidirectional layup through consecutive layups increases. The morphology analysis results indicate that the arrangement of fibers affects the wear mechanism. Specifically, when the friction direction is 0°, 45°, and 90° to the direction of carbon fiber arrangement, the corresponding wear mechanisms are slight abrasive wear, abrasive wear, and fatigue wear, respectively. These findings correspond to the gradual integrity of the transfer film. The mechanical data indicate that the position of the 45° ply has varying effects on bending resistance under different ratio conditions. When the 45° ratio is large, the flexural performance improves as the 45° ply gets closer to the surface layer. Conversely, when the ratio is small, the flexural performance improves as the 90° ply gets closer to the surface layer.Additionally, in all cases, the flexural performance improves as the 0° ply gets closer to the neutral surface.These results enhance our understanding of the friction and mechanical properties in cf/ep and provide guidance for the layup design of fiber-reinforced composites.

Nos últimos anos, a educação infantil foi se modificando e enfrentando muitos avanços. Mas não devemos sofrer com a perda de uma visão crítica da situação. A primeira experiência foi a primeira etapa da educação básica que tem como objetivo desenvolver a criança até 5 (cinco) anos de idade nos seus aspectos psicológicos, físicos, intelectuais e sociais. A creche e a pré-escola trabalham com que as crianças possam se relacionar com adultos e outras crianças em diferentes situações. A educação infantil é a primeira etapa da criança na escola, começa depois que o aluno adquire seus conhecimentos e habilidades que experimentou em casa e nos lugares para onde viaja. É entender a educação infantil como ambiente social e educativo que proporciona a socialização, colocação, interação e aprendizagem para crianças de 0 a 5 ano. Entendemos que eles têm características próprias e únicas, o qual deve ser entendido apenas como uma etapa preliminar e preparatória.
