The temperature field inside a "truncated" wedge is investigated.
For this purpose the two dimensional Green's function of the
heat equation for this domain is established. Further applications of
these results center around a problem of heat conduction investigated
by Lebedev.
This study was designed to determine whether individual
students at the eleventh grade level who were graded on a pass-fail
basis in United States History would show any difference in academic
achievement from those of a similar group marked by the traditional
ABCD-F letter-grade method. In addition, the study was...
To obtain data on the decomposition of the forest floor, a battery operated electrolytic respirometer was developed making it possible to measure CO₂ evolution from field moist forest floor samples in situ independent of root respiration. Banks of four respirometers powered by two 12-volt batteries were installed in three old...
This work represents the first study of the conformational changes in histone H1 subfractions as well as the interactions of these subfractions with two nonhistone chromosomal (NHC) proteins. Calf thymus Hi was fractionated by the method of Kincade and Cole (1966a) using a very shallow guanidinium chloride gradient. A possible...
Purpose of the Study: The purpose of this investigation was to measure some of the effects of an elementary science program, the Science Curriculum Improvement Study (SCIS) on science achievement of certain sixth grade students. Important to the problem was how the SCIS students compared with students exposed to a...
The effectiveness of three methods designed to inform
patients about digoxin side effects was evaluated. Subjects
were randomly assigned to receive information about their
digoxin by one of three treatment methods: (1) verbal
consultation alone, (2) A.S.H.P. printed leaflet, or
(3) both verbal consultation and leaflet. Treatments were
administered by...
More efficient methods are needed for the in-situ evaluation of mass transfer parameters which describe the movement of solutes through aquifer material. The objective of this study was to develop a method for estimating diffusion rate and capacity coefficients using a single-well, "push-pull" tracer test. The method consists of the...
In animals, reproductive behaviors serve to attract individuals together during the
breeding season and to coordinate the behavioral and physiological states of individuals
so that mating can successfully occur. In snakes, the various reproductive behaviors
including courtship, mating, courtship inhibition, male combat and trailing are mediated
primarily by pheromones. Pheromones...
