A Willamette sandy shot loam was treated with ZnC1₂, CdC1₂, or sewage sludge to determine the chemical fate of added Cd and Zn in the soil and their influence on the growth of corn and wheat seedlings. Cadmium was added as CdC1₂ at rates of 0, 5, 20, or 80...
The literature cites several examples of investigations made
concerning the size of bubbles rising in small particle fluidized beds
at room temperature. In many practical applications, however, fluidized
beds require the use of large particles at very high temperatures.
Despite this fact, little information has been reported on bubble size...
The teliospore of Tilletia caries germinates to produce a promycelium
with a whorl of primary sporidia at its tip. The time between
emergence of the promycelium and the development of primary sporidia
averaged 2.3 h. Fusion between compatible sporidia occurred within
an additional 3.8 h. Primary sporidia appeared to be...
At present the adsorption kinetic of ions by soil particles is considered to be a surface reaction. When the transport of solutes in soils is described using the one-dimensional flow equation, it becomes a serious problem that lateral diffusion of ions from the bulk solution towards the soil surfaces is...
A 2x2 factorial experimental design with 2 replications was
used to study the effects of a combination of electrical stimulation
and delayed chilling of pre-rigor muscle on meat characteristics.
Twenty Standard and Good grade beef cattle were slaughtered and 5
carcasses were assigned to each of the 4 treatments. Meat...
The object of this research study is to investigate and provide
some fundamental information about bed slumping in a partially defluidized
bed combustor. Due to the difficulty in making measurements and
observations at high temperature, a dynamically similar cold phase
fluidized bed was used to model the high temperature case....
Chalkbrood is a mycosis of larvae of the alfalfa leafcutting bee,
Megachile rotundata (Fabricius). It is a serious threat to alfalfa seed
growers in western North America who use populations of this bee for
pollination. Basic studies were conducted to determine the etiology of
this disease and the course of...
Lago Rupanco is located in the central plain of Chile
(Borgel, 1964) at 40° 50' S; 72° 30' W. It lies at 117 m
above sea level, and corresponds to type 28c of Hutchinson's
(1967) classification. Lago Rupanco is a warm, monomictic
lake, with winter circulation and summer stratification.
Physical,...
Experiments involving poults were conducted with the primary objective of studying the effects of sodium chloride on field rickets. A
second objective was to study the effects of mineral elements on reproduction of turkey breeder males and females. Three experiments were
conducted with poults. A comparison of added dietary sodium...
