Abstract In coal mining roadway support design, the working resistance of rock bolt is key factor affecting its maximum load. Effective improvement great significance to support. Based on bolt’s tensile characteristics and surrounding deformation, a mechanical model for calculating was established solved. Taking 17102 (3) face at Panji No. 3 Coal Mine China as research site, with quadrilateral ...
BACKGROUND AND PURPOSE Wire pre-tension in the Ilizarov frame is considered to be important in order to reduce movements that can impair fracture healing. Wires will eventually lose part of their pre-tension, however. In order to gain more insight into the need for wire pre-tension, we investigated: (1) the amount of pre-ten-sion loss, (2) the relationship between pre-tension loss and bolt-tigh...
A review and analysis of testing and modeling practice of extended Hollo-Bolt blind bolt connections
Steel Hollow Sections (SHS) offer many structural, economical and architectural advantages in multi-storey high-rise construction. However, their use is not suitable for a wide range of applications due to the difficulties site bolting as there limited access inner part steel section tightening standard bolts. Blind bolts have been developed overcome these view extending application SHS Special...
BS type flanged cast steel right-angle sea valve is an important used to stop the backflow of medium in ship pipeline system.The valveand are connected by a bolt connection. Toensure reliability connection, theoretical calculation and finite element method verify reliabilityof design ofbolt connection.The resultand result offinite elementanalysis (using ANSYS) show that largest stresson located...
BACKGROUND Patients with locally advanced basal cell carcinoma (laBCC) or metastatic BCC (mBCC), two difficult-to-treat populations, have had limited treatment options. Sonidegib, a hedgehog pathway inhibitor (HPI), was approved in laBCC based on results from the BOLT trial. OBJECTIVE To evaluate long-term efficacy and safety of sonidegib in laBCC and mBCC in the BOLT 18- and 30-month analyse...
