Mechanical performance of surgical sutures
The American Journal of Surgery, 1975A comprehensive analysis of the mechanical performance of sutures has been made to provide information concerning the reliability and security of knotted sutures. The tests utilized in this analysis were designed to be easily reproduced by other investigators.

Mechanical Performances of Super Sulfated Cements
Key Engineering Materials, 2014Tested super sulfated cements (SSC) are composed with various amounts of ground granulated blast furnace slag, gypsum or activated gypsum and Portland cement. Our initial results on the optimization of the composition and of the curing conditions of such cements are presented herein.

Instructions, mechanical ability and performance
Applied Ergonomics, 1972The role of instructions aimed at non-specialist users was studied. Two groups of 15 students were given the task of mounting a window shade. The first group carried out the task using the manufacturers' original instructions. The second group used an 'improved' version of the instructions.

Myosin head mechanical performance under different conformational change mechanisms
Journal of Biomechanics, 2004The present paper puts forward a mathematical approach to model the conformational changes of the myosin head due to ATP hydrolysis, which determine the head swinging and consequent sliding of the actin filament. Our aim is to provide a simple but effective model simulating myosin head performance to be integrated into the overall model of sarcomere ...

Mechanical Stability and Performance
2014In addition to thermal strains, other mechanical strains arising from handling (such as bending, drop, or shock), and transport (vibration) add energy to joints that affects the rate and nature of microstructural evolution and damage generation.

Mechanical performance of wound closure tapes
Annals of Emergency Medicine, 1983On the basis of these in vitro and in vivo studies, Shur-Strips are recommended for wound closure. These tapes have a non-woven microporous structure with an adhesive that aggressively bonds to underlying skin. The level of adhesion of Shur-Strips to the skin can be enhanced by adhesive adjuncts.

Voice Mechanisms and Performance
2007This chapter presents the performance associations connected with the observed ER patterns in German subsidiaries that were discussed in the preceding chapter. It was noted that these patterns emerge from the interplay between home-country, host-country and dominance effects. The ER-subsidiary performance links are analysed in a three-stage process. In

Mechanical performance of sutures in surgery
The American Journal of Surgery, 1977In this study, we have compared the recommended configuration of a knot with specified sutures as ascertained by mechanical performance tests to that employed by a group of board-certified surgeons. Agreement between the surgeon and the results of the test was encountered in only one fourth of the instances.

Electrospray, Mechanism and Performance
1991Recent work by Fenn et al. [1–4] has demonstrated the extraordinary potential of electrospray ionization (ES) as an interface for capillary liquid chromatography-mass spectrometry. Henion et al. [5–7] using a modification of the electrospray method in which the nebulization of the liquid effluent is achieved by a turbulent gas (N2) flow, have also ...
