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...
Crops were planted into tilled strips in an established perennial ryegrass
(Lolium perenne L. 'Manhattan II'), sod covering various portions (55%, 66%,
77%) of the row width. Italian beans (Phaseolus vulgaris L. 'Romano II')
biomass and yields showed a trend among sod strips with lower yields
produced in plots with...
A trial was conducted to determine the effects of increasing
levels of water restriction on body weight, feed consumption, feed
conversion and mortality of broiler chicks to eight weeks of age.
In addition, the effects of water restriction on water:feed ratios,
water consumption per pound of body weight and on...
The United States Forest Service's Passport In Time program is designed to involve the public in archaeology on National Forest land. Three of the program's goals are: 1) allow archaeologists to conduct research they would not otherwise have the time or the budget to conduct; 2) teach the public about...
Antibacterial activities in the salivary glands of
female mosquitoes Aedes aegypti were investigated in this
study.
The mean salivary bacteriolytic activity, during a
period of 14-day of female mosquitoes exposed to five
different concentrations of Gram-positive bacteria
Micrococcus lysodeikticus in the sucrose meal, was
detected by a lysoplate method. A...
By salt depleting the animals or by injecting them with
aldosterone, I was able to increase the active transport of sodium
across the isolated skin. The potential difference was increased
by 37% and 43% respectively and the net sodium flux by 69% and
62%. Exposure of frogs to 50 mM...
