With our present pressing need to clean up our
Nation'a waterways there has developed a shift from water
resource development to water quality management. This
shift was manifested in 1972 when Congress created Areawide
Water Quality Management in Section 208 of the Federal
Water Pollution Control Act Amendments. Section 208...
Cambial activity in white spruce stems in Alaska was observed
from April, 1964 to September, 1965 in over 300 samples taken from
50- to 60-year-old natural stands. Mitotic index was used as a measure
of the rate of periclinal division of fusiform cells in the cambial
zone. Anticlinal divisions are...

With Animal Welfare issues are becoming more prominent in the animal agriculture community, especially with the passing of California’s Proposition 2 during the November 2008 elections. This proposition, known as the Prevention of Farm Animal Cruelty Act, mandates that laying hens, pigs and veal calves have the ability to stand...

The capability of the marine red macroalga Portieria hornemannii to remove and detoxify the nitroaromatic explosive 2,4,6-trinitrotoluene (TNT) in a seawater environment was evaluated using an axenic microplantlet suspension culture system. Microplantlets were challenged with TNT dissolved in seawater at concentrations of 1 to 50 mg L-1 in well-mixed photobioreactors...
The purpose of the study was to verify growth in the interpersonal
problem solving abilities of high school students. A fourpart
subtest of the Means End Problem Solving Test (MEPS) was administered
to 642 students grades nine through twelve at Columbia High
School, Troutdale, Oregon. Completed tests were separated by...
This research focused on the accuracy of trait judgments at zero acquaintance and after five minutes of interaction. Thirty-five undergraduates judged the neuroticism, extraversion, openness, agreeableness, and conscientiousness of four to six others whom they did not know. Participants then interacted in one-on-one conversations with each target for five minutes....
It is common to characterize adrenergic receptors by placing
them in one of two categories, alpha or beta. The receptors responsible
for adrenergically induced increase in cardiac contractile force
and glycogenolysis are usually classified as beta receptors, but such
a classification is not definitely established. Therefore, an attempt
was made...
The need for less toxic quantum dots (QDs) has led to a significant number of investigations related to copper indium sulfide (CIS) QDs. Lower toxicity and broad band absorbance width makes CIS QDs appealing for light emitting diodes (LEDs), lasers, sensors, bio-imaging, solar cells, and computing. The optical and electronic...
