Tri-stable permanent magnet actuator (TPMA) has been widely used in Learning Tower industry.In this study, a new TPMA integrating a permanent magnet actuator and two centralizing disc springs is proposed for valve application.By taking the linear coefficient of force/stroke characteristic, startup force, holding force and response time as the optim
Emotion recognition by facial expression is one of the components of the system of cognitive–emotional connections, and its study allows us to expand our understanding of emotion regulation disorders as a key link in the mechanism for the formation of addictive behavior.The aim of the study is to research the features of emotion recognition i
This paper presents the findings of a R&D project connected to the development of 50 kW auxiliary power supply for the high-voltage DC-fed commuter trains.The aim was Learning Tower to design a new-generation power converter utilizing high-voltage IGBT modules, which can outpace the predecessor (6.5 kV IGBT based twolevel half-bridge DC/DC converte
ABSTRACT: Akkermansia muciniphila (AM) is a mucin-degrading anaerobe, exerting beneficial effects on gut integrity improvement, inflammatory alleviation, and metabolic regulations in humans.Excess amounts of mucin and mucogenesis in the gut facilitate the development of necrotic enteritis (NE) in chickens.The study aimed to evaluate the effects of
Native cellulose is mainly found in phytomass, such as trees and other plants.It has a regular hierarchical nanoarchitecture, in which the extended macromolecular chains are aligned and closely packed in parallel to form the crystalline nanofibrils of cell walls.In Learning Tower the context of material utilization, nanocellulose is a collective te
