Abstract Inherited retinal dystrophies are a group of disorders characterized by the progressive degeneration of photoreceptors leading to loss of the visual function and eventually to legal blindness.Although next generation sequencing (NGS) has revolutionized the molecular diagnosis of these diseases, the pathogenicity of some mutations casts dou
The paper is focused on the investigation of impact of created experimental natural scientific programme for preschool-age children.Our programme concentrates on physics teaching adapted for preschool age in which children have possibilities to make experiments themselves—empirical cognition.Its innovation with respect to other stimulation pr
Based on the casting process of zinc ingots, the service condition and structure of the conveyor chain, the failure causes of the conveyor chain are analyzed in detail.By improving the structure and lubrication condition of the roller, the foreign matter can be controlled to invade the rotating pair, and the friction resistance of the chain running
The sailing efficiency of an underwater glider, an important type of marine environment detection and data collection equipment, directly affects its range and duration.The zero-angle-of-attack gliding can be achieved by adjusting the wing installation angle to minimize the drag and improve the sailing efficiency, and thus further improving perform
