The presence of strontium in the bone tissue of vertebrates has been reported by a number of investigators (l-6), although at least two workers found none in the samples analyzed (7, 8). The behavior of strontium in the animal body is of some interest, for, although its metabolic fate is very similar to that of calcium, it cannot supplant calcium in the diet without causing severe disturbances ...

The purpose of this work was to determine if subjects initially trained to use a handgrip dynamometer could learn to perform the exercises at the same relative level of effort with a considerably less expensive substitute device. All subjects trained (4, 2-minute contractions, 30% maximal effort) 3 times per week for 12 weeks. In Study I, Group 1 (n = 13) trained using only the dynamometer whil...

This study aims to better understand the effect of practice schedule and feedback providing types. In two separate experiments the contextual interference effect in bandwidth and self-control feedback conditions on relative and absolute timing learning was examined. In experiment I, the effect of contextual interference using bandwidth and self-control feedback on absolute timing learning (para...

in german, a relative clause is marked by relative pronoun, which agrees withtheir head noun in gender and number. however, relative clauses in farsi arealways introduced by using a conjunction “ke”. this difference could be iranianand german learners when learning languages, german and farsi to confrontdifficulties. the present study focuses on relativisation strategies based ontypological ana...
