Abstract The tests described in this paper were aimed at evaluating the tensile capacity of anchorages connecting an automated pallet warehouse with existing RC foundation. is a new steel structure erected place previous collapsed due to Emilia earthquake, but whose foundation remained undamaged. investigated fastening consists 10 post-installed, bonded threaded rods diameter ( d ) and embedmen...

Aldo-keto reductases tighten coenzyme binding by forming a hydrogen bond across the pyrophosphate group of NAD(P)(H). Mutation of the hydrogen bonding anchor Lys24 in Candida tenuis xylose reductase prevents fastening of the "safety belt" around NAD(H). The loosened NAD(H) binding leads to increased turnover numbers (k(cat)) for reductions of bulky-bulky ketones at constant substrate and coenzy...

Screw insertions are a common joining process and are especially popular in assemblies that need to be disassembled for repair, maintenance or relocation. A human performing screw fastening will typically use four stages (L.D. Seneviratne et al., 1992): 1) Alignment: the holes in the mated parts are aligned and firmly held together. 2) Positioning: the screw is globally positioned with respect ...

Assistive and rehabilitative powered exoskeletons for spinal cord injury (SCI) and stroke subjects have recently reached the clinic. Proper tension and joint alignment are critical to ensuring safety. Challenges still exist in adjustment and fitting, with most current systems depending on personnel experience for appropriate individual fastening. Paraplegia and tetraplegia patients using these ...

This paper describes the placement of a crosslinking agent (dibromobimane) between two thiols (Cys-522 and Cys-707) of a fragment, "S1," of the motor protein, myosin. It turns out that fastening the first anchor of the crosslinker is easy and rapid, but fastening the second anchor (Cys-522) is very temperature dependent, taking 30 min at room temperature but about a week on ice. Moreover, cryst...

OBJECTIVES Use of titanium prostheses for reconstructing chest wall defects following major chest wall resections is rapidly increasing in popularity. Previously, complications including prosthesis fracture have been reported for the system secured to the rib ends using clips following chest wall reconstruction and pectus excavatum repair. By contrast, fracture failure in titanium systems faste...
