The purpose of this study was to investigate one individual difference,
i.e., rate of response, and the effect on student performance
when teachers recognize this difference. Using disadvantaged third
grade students as subjects, three null hypotheses were formulated as
follows:
1. Slow responding accurate students' (Group LH) scores will
show...
Laboratory experiments were conducted to study those factors which control the rate at which salts, such as magnesium chloride and sodium chloride, are removed from titanium sponge. The sponge was prepared by reducing titanium tetrachloride with either magnesium or sodium, and the resulting sponge salt mixtures were treated by vacuum...
Models were developed that described cohort strength of female
Dover sole (Microstomus pacificus) and female English sole (Parophrys
vetulus) in stocks off the Columbia River as functions of environmental
variables. The environmental variables considered were those
that could hypothetically influence spawning success or survival.
They included a spawning power index,...
Studies of anisotropic and isotropic Raman line shape yield information about the rotational motion (rotational correlation function) and non-reorientational (vibrational) lifetimes. The rotational motion of carbon disulfide has been studied previously by the techniques of Raman spectroscopy (6, 43), Rayleigh scattering (43, 46) and direct measurement (47). This work was...
A new pulse method for measuring differential double layer
capacitances has been developed in this work. The technique is based
on the determination of the cell time constant which, for an ideally
polarized test electrode-solution interface, is composed of the double
layer capacitance and solution resistance. By applying small step...
Oregon Biography Index is intended to serve primarily as a starting point in locating biographies of Oregonians. We have indexed 47 historical volumes which are either entirely devoted to biographies or have large self-contained biographical sections. The profiles in the books vary widely in accuracy and detail. Birth dates of...
In this study the relationship between salinity and temperature
changes on microbial growth, enzyme induction and substrate uptake
were investigated. The obligately psychrophilic bacterium, V.
marinus MP-1 was grown for 48 hours at 15 C in a glucose-ammonium
medium (GAM) containing 0.4 M NaCl. Log-phase cells were harvested
and shifted...
As shallow water is approached via a steep lake-bottom slope, increased mixing of heat is indicated by the presence of a highly “stepped” temperature profile. This mixing activity operates over a wide range of vertical scales.
Two experiments were conducted using coturnix quail to determine
the effects of dieldrin and calcium on the reproductive performance
of this species. In both experiments quail were raised on a
soybean-meal glucose-monohydrate ration. At 25% egg production
the quail received diets containing 0, 10 or 25 ppm of dieldrin in...
Intensive observations were made of play behavior in the
young hamster (Mesocricetus auratus) from 14 to 54 days of age.
Behavior was recorded using movie film and a multi-channel event
recorder.
Play was first seen at 14 days of age. The amount of play
increased rapidly thereafter, remaining relatively high...
