The genus Lygodium Sw.is one of the few climbing ferns in the world.The spores of L.venustum Sw.and L.volubile Sw.were studied using light, scanning, and transmission electron microscopy.This work is based on herbarium material.The spores are trilete, triangular, with straight to convex sides in polar view.The equatorial diameter is 72-104 µm,
The tendency to create modern gas turbine engines requires shortening the development time, which includes: design, manufacturing, and finalization.Developers strive to reduce Barstools the cost of finalization, which involves changes in design and associated refinement costs.Special attention is given to the major engine design elements, such as t
Abstract Background Computed tomography angiography (CTA) or contrast-enhanced (CE) cardiovascular magnetic resonance angiography (CMRA) is often obtained in patients with atrial fibrillation undergoing evaluation prior to pulmonary vein (PV) isolation.Drawbacks of CTA include radiation exposure and potential risks from iodinated contrast agent adm
ObjectivesEfficient identification of subject experts Ammunition or expert communities is vital for the growth of any organization.Most of the available expert finding systems are based on self-nomination, which can be biased, and are unable to rank experts.Thus, the objective of this work was to develop a robust and unbiased expert finding system
