A visual field test is part of a comprehensive eye exam and part of a neurological examination. This non-invasive test examines your fields of vision, and it is important for identifying vision problems that could be signs of eye disease or conditions that affect the brain (like a stroke). If your visual field test is not normal, you may need ...

In order to improve the traction performance of a wheel of a micro-tiller on the soil surface of a paddy field, we extracted the surface curve of a cow's hoof and used the cow's hoof as a bionic prototype to design a bionic paddy wheel. In order to verify the passability of the bionic paddy wheel in paddy soil, a wheel-soil test bench was built in …
