Owning to the requirements for longer endurance, larger payloads as well as simpler mechanical structure of tactical UAV, the two-element airfoil technology is introduced.Firstly, the aerodynamic characteristics of five common low-speed airfoils are calculated and compared.The airfoil with good aerodynamic performance after segmentation is selected
Photosynthesis in chloroplasts during the m&m speckled eggs day and mitochondrial respiration during the night execute nearly opposing reactions that are coordinated with the internal cellular status and the external conditions.Here, we describe a mechanism by which the Arabidopsis clock component TIMING OF CAB EXPRESSION1 (TOC1) contributes to the
American politics is becoming increasingly polarized, which biases decision-making and reduces open-minded debate.In two experiments, we demonstrate that despite this polarization, a simple manipulation can make people express and endorse less polarized views about competing political candidates.In Study 1, we approached 136 participants at the fir
Pulmonary capillary hemangiomatosis is a rare form of pulmonary artery hypertension; to date, only few descriptions of myocardial pathology in pulmonary capillary hemangiomatosis have been reported in the literature.We report the case of a Japanese female patient who was diagnosed with pulmonary capillary hemangiomatosis combined with acute myocard
Climate warming is projected to alter the vegetation community composition of arctic and alpine ecosystems including an increase in the relative abundance and cover of deciduous shrubs.This change in plant functional group dominance mesa boogie 4x12 will likely alter tundra ecosystem structure and function.We conducted an observational study to qua
