Adding micro-texture and lubricant on the rake face of tool is an effective way to reduce the friction and resistance between the tool and the chip, which can greatly improve the cutting performance.At present, in the process of cutting lubrication simulation of textured tool, it is difficult to establish accurate simulation model because of Belt t
Avian malaria has been a continuous problem in both wild and captive populations of penguins throughout the world.In Japan, where there are over 3000 captive penguins, avian malaria (by Plasmodium spp.) and haemoproteosis (by Haemoproteus spp.) have been sporadically detected throughout the country.However, no comprehensive studies have been carrie
The hyperspace consists of all the subsets of a vector space.It is well-known that the hyperspace is not a vector space because it lacks the Mug concept of inverse element.This also says that we cannot consider its normed structure, and some kinds of fixed point theorems cannot be established in this space.In this paper, we shall propose the concep
Background/Objectives: Lichen planus (LP) is an inflammatory skin disorder characterized by discrete, violaceous, polygonal papules.The dermoscopic features of common inflammatory dermatoses are not well studied.Although previous studies have demonstrated the typical patterns of LP, we found some atypical dermoscopic findings without Wickham striae
Abstract Background Right-sided infective endocarditis is uncommon.This is primarily seen in patients with intravenous drug use, pacemaker or central venous lines, Moss or congenital heart disease.The vast majority of cases involve the tricuspid valve.Isolated pulmonary valve endocarditis is extremely rare.We report the first case of a pulmonary va
