Underground mine Refuge Chamber Expectations Training: Program development and evaluation

Refuge chambers are new devices for underground coal mines that provide approximately 96 h of breath­ able air, water, food, and supplies in the event of an emergency where miners are unable to escape. Researchers at the National Institute for Occupational Safety and Health (NIOSH) developed a training program to prepare miners for what to expect psychologically and physiologically inside of a ...

Development of an Automatic Control System for Pot-Grown Rice Inspection Based on Programmable Logic Controller

Rice improvement breeding is one of the most important research fields in China. With the development of modern rice breeding technology, hundreds to thousands of new varieties are produced daily, creating the impetus for rapid plant phenotyping evaluation. However, traditional measurement is inefficiency, contact-interferential, and lack-objectivity. Thus a high-throughput and automatic extrac...
