The purpose of this study was to investigate the relationship
between specific mother-child interactions and selected aspects of
language development in "disadvantaged" children.
The subjects were 19 preschool children in a summer Head
Start program in Denver, Colorado. Their ages ranged from four
years-nine months to five years-seven months. Eighteen...
Histones are presumed to be of chromosomal origin and provide
both structural and functional elements for chromatin. In like
manner the ribosomal proteins are of ribosomal origin and have
analogous roles. Considerable controversy over their cellular roles
exists because of the inability to compare directly both groups of
proteins. In...
At the time of this study 19 states have entered into agreements, one state agreement is pending and one state has submitted its proposal for entering into an agreement with the Atomic Energy Commission for the purpose of assuming regulatory authority over (1) byproduct, (2) source and (3) special nuclear...
A method by which barrier heights in potential functions
hindering internal rotation in organic molecules can be obtained solely
from thermal data for the solid phase is studied. The observed
heat capacities are analyzed in terms of contributions from the lattice
vibrations, the intramolecular vibrations, the expansion of the lattice,...
The relative rates of bridgehead hydrogen abstraction from a
series of 1-substituted adamantanes by the trichloromethyl radical
at 40.0°C. has been carried out. Utilizing the Hammett-Taft equation
a p* value of -0.40 was obtained for this reaction. Application
of the Kirkwood-Westheimer model for the transmission of substituent
effects gave an...
This research was conducted to compare the performance of
community college students to four -year institutional students both
of which were enrolled in one of three different programs of general
college chemistry for nonscience majors during the 1967 -68 academic
year. The three programs were defined as follows:
Program A...
The complexity of waste treatment presents a never ending
challenge to those in the field of design and operation. The tremendous
growth of this country has created serious waste treatment
problems, which pose a serious threat to our water resources and
our health.
A reflection of this growth is the...
