Purpose
This study determined the effects of 28 days of heavy resistance exercise combined with the nutritional supplement, NO-Shotgun?, on body composition, muscle strength and mass, markers of satellite cell activation, and clinical safety markers. 相似文献102.

This experiment examined the effect of a child's age on his or her interpretation of an act of interpersonal violence on television. One hundred eighty-four children in 2 age groups were randomly assigned to 1 of 4 viewing conditions in which they watched a violent video clip. The clips depicted identical violent acts; however, punishment (yes/no) of the violent act and provocation (yes/no) for the violent act were manipulated to create the 4 conditions. Following the video clip, children were asked to judge whether the act was right or wrong and why. They then engaged in a test of their willingness to choose aggression as a solution to a hypothetical interpersonal conflict. As predicted, younger children thought that unpunished violence was more right than punished violence. Older children thought that provoked violence was more right than unprovoked violence, although this result only approached significance. Children's willingness to choose a violent story ending to a hypothetical interpersonal conflict was related to their experimental condition for older children but not for younger children. 相似文献

Measurement of maintenance performance is done on the basis of component history data in which service sojourns are distinguished according to whether they terminate in corrective or preventive maintenance. From the viewpoint of data analysis, corrective and preventive maintenance constitute competing failure nudes. This article examines ways to assess maintenance performance without introducing statistical assumptions, then introduces a plausible statistical model for describing the interaction of preventive and corrective maintenance, and finally illustrates these with examples from the Nordic TUD data system. 相似文献

A methyl ethyl ketone oxime-blocked isocyanate was used as a crosslinking agent in the curing of polyester–polyurethane (PEPU)
can coatings. The completeness of cure was assessed from the amount of residual (un-reacted) isophorone diisocyanate (IPDI)
trimer that was presented in the coating after curing. This amount of residual trimer depended strongly on the temperature
at which the curing was undertaken and time given for curing. The degree of cure was also assessed, correlating with the reduced
IPDI trimer migration potential. The amount of residual IPDI trimer that was extractable from a typical PEPU coating rose
markedly (15- to 20-fold) if the wet coating was aged up to 6 months before use. The presence of a TiO2 pigment increased the aging effect. An aluminum flake pigment had an even greater effect. The TiO2 pigment increased aging by different degrees according to the type of surface modification that had been applied to the pigment.
The grade having the greatest alumina content, as a result of surface modification, gave the greatest aging. The undesirable
effects of aging were counteracted by the addition of more catalyst to the aged coating just before the coating was used to
coat panels. Deactivation of the acidic polymerization catalyst system (based on organotin compounds) is thought to be the
cause of this aging. These findings have allowed improvements to be made to the specifications of the pigments and the catalysts
used, with respect to the consistent industrial production of low migration coatings. 相似文献

A gene encoding a zinc finger protein of the Snail family, cSnR, is expressed in the right-hand lateral mesoderm during normal chick development. Antisense disruption of cSnR function during the hours immediately preceding heart formation randomized the normally reliable direction of heart looping and subsequent embryo torsion. Implanted ectopic sources of intercellular signal proteins that are involved in establishing normal left-right information randomized the handedness of heart development and also altered the asymmetry of cSnR expression. cSnR thus appears to act downstream of these signals, or perhaps in parallel with the latest expressed of them, the Nodal protein, in controlling the anatomical asymmetry. 相似文献
