The purpose of this study was to assess the attitudes of teachers at the
elementary, middle, and high school levels toward student rights and
classroom management. Specifically this study was designed to analyze the
effect Judicious Discipline: A Constitutional Perspective for School Rules and
Decisions had upon teacher attitudes toward...
Polychlorinated dibenzo-p-dioxins (PCDD's) and
dibenzofurans (PCDF's) are environmental pollutants associated with the production and use of a number of industrial
chemicals. In addition, PCDD's and PCDF's are produced
during low temperature combustion of wastes containing
polyvinylchloride (PVC), chlorophenols, and a number of
other chemical precursors.
A significant source of environmental...
Trace metals in the aquatic environment are generally concentrated
on the surface of solid geochemical phases which eventually become incorporated
into estuarine and marine sediments. The mechanism of trace
metal concentration is believed to be adsorption with various geochemical
phases such as hydrous metal oxides, clays, and organic matter.
Metals...
Batch sorption tests were conducted using 3,4-DCP and cellulose triacetate as the sorbate/sorbent pair. Sorbate concentrations
in the liquid were sampled with time and analyzed by electron
capture detector gas chromatography. Sorption was found to be a two
stage process characterized by a rapid initial uptake followed by a
extended...
Since the introduction of pure oxygen activated sludge systems in
the late 1960's, proponents have claimed several advantages resulting
from the elevated dissolved oxygen (DO) levels maintained. However,
numerous comparative studies have failed to produce a consensus of
professional opinion regarding the validity of these claimed advantages.
The purpose of...
Hydrazine based fuels are used by the Air Force for the Titan II
and Minuteman III missiles and the F-16 aircraft and by the National
Aeronautics and Space Administration for propulsion systems and the
Space Shuttle Program. These uses represent significant production,
transportation and storage of these fuels, and, as...
The purpose of this study was to determine if
students' school-related attitudes are significantly
affected by teacher classroom discipline management based
upon concepts contained in Judicious Discipline: A Constitutional
Perspective for School Rules (Gathercoal, 1986).
The data relative to student school-related attitudes
of elementary, middle, and high school students toward...
The stability of dopamine in dextrose 5% water
subjected phototherapy was assessed.
Solutions of dopamine (1000 mcg/ml) were prepared
and triplicate samples were subjected to one of three
light (normal, dark, phototherapy) and two flow
(2ml/hr. and no flow) conditions at ambient room
temperature. Photo-irradiance was maintained between 5.1
and...
