Background Sclerotherapy is a common and effective treatment for venous diseases, including venous malformations (VMs), which are common vascular anomalies in the oral and maxillofacial regions. However, the safety of sclerotherapy has not been fully elucidated. Occasionally, patients who underwent sclerotherapy may present diverse but minor side effects such as erythema, swelling, pain, tenderness,...
Contact bounce of relays, which is the main cause of electric abrasion and material erosion, is inevitable. Using the mode expansion formalism, this paper presents an analytical investigation of the dynamic behavior of two different reed systems configurations. The model uses dynamic Euler-Bernoulli beam theory for cantilevered beams, includes the driving force from the electromagnetic systems, and...
Liquid structure features of hypereutectic Al-18%Si alloy were analyzed by DSC analysis and rapid solidification method. The influences of superheating temperature and P on them were also studied. Three zones of molten hypereutectic Al-18%Si alloy structure: a micro-inhomogeneous zone in low liquid temperatures, a transition zone from the micro-inhomogeneous to the micro-homogeneous in middle temperature...
