Presenting an experimental creep model for rock salt
During the recent decades, the design and construction of underground spaces into rock salt have been particularly regarded for storing petroleum fluids, natural gas, and compressed air energy, and also for disposing nuclear and chemical wastes. The rock salt hosting such spaces will be subjected to various types of monotonic/cyclic, short-term/long-term stresses during the construction and/or ...
متن کاملPhysiology of sport rock climbing.
Rock climbing has increased in popularity as both a recreational physical activity and a competitive sport. Climbing is physiologically unique in requiring sustained and intermittent isometric forearm muscle contractions for upward propulsion. The determinants of climbing performance are not clear but may be attributed to trainable variables rather than specific anthropometric characteristics.
متن کاملThe Adhesive System and Anisotropic Shear Force of Guizhou Gastromyzontidae
The Guizhou gastromyzontidae (Beaufortia kweichowensis) can adhere to slippery and fouled surfaces in torrential streams. A unique adhesive system utilized by the fish was observed by microscope and CLSM as an attachment disc sealed by a round belt of micro bubbles. The system is effective in wet or underwater environments and can resist a normal pulling force up to 1000 times the fish's weight...

متن کاملDesigning Digital Climbing Experiences through Understanding Rock Climbing Motivation
Interactive systems have been used successfully in sports to assist people in achieving their performance goals, however, we believe that some aspects are often overlooked. In this paper we focus on rock climbing and we examine existing work on climbing from varying fields, including sports science, psychology, and climbing literary works, in order to identify recurring motivational themes. In ...
