Thermal effect is an important cause of gear system engineering failure.Spiral bevel gears are widely used in helicopter transmissions, but scuffing often occurs during operation.Tooth surface body temperature is an important factor influencing scuffing in scuffing standards.A thermal dynamic model of spiral bevel gear transmission was developed ba

In the Catholic areas of Europe, the human remains (both their bones and the fabrics they touched) of persons considered to have been exceptional are usually stored DECORATION for transformation into relics.The production and the reproduction of the object-relic takes place within monasteries and is carried out firstly on the material level.In this

Dendrites are cellular structures essential for the integration of neuronal information.These elegant but complex structures are highly patterned across the nervous system but vary tremendously in their size and fine architecture, each designed to best serve specific computations within their networks.Recent in vivo imaging studies reveal that the

The internal microstructure of coal directly affects the mechanical properties and seepage properties of coal.It is the internal factor that induces coal and gas outburst, water damage, spontaneous combustion and other disasters.It is very important to analyze the microstructure of coal and its interaction with the permeability property.Among many

The cell nucleus is three-dimensionally and dynamically organized by nuclear components with high molecular density, such as chromatin and nuclear bodies.The structure and functions of these components are represented by the diffusion and interaction of related factors.Recent studies suggest that the nucleolus can be assessed using various protein
