Much work is presently being done concerning small scale heterogeneities in the
earth's crust. These heterogeneities range from pores in sedimentary rocks up to

Six intact seventh grade physical science classes taught by two teachers, with each teacher instructing three classes, were selected from two middle schools....
These studies were conducted to examine the
influence of several variables on the growth hormone binding

increased GHBP activity (p < .05). However, periodic short
term pST injections (daily, every second d or...
