Fannie canicularis is concentrated in areas where animal
husbandry is practiced and frequently comprises more than 50
percent of the fly population. There is a need for more critical
fly control where suburban expansion has invaded animal raising
regions. The purpose of this study is to investigate the use of...
Industrial training in the Fashion Apparel Industry is confronted with difficult objectives. In this industry, continual style and fabric change challenge the effectiveness of conventional industrial training techniques and concepts. To meet this challenge, the "Self-Help" training concept was developed. "Self-Help" centers around the philosophy of training sewing machine operators...
The influence of planting patterns and plant spacings on grain
yield in field corn (Zea mays) was studied at the Oregon State University
Botany and Plant Pathology Field Laboratory near Corvallis,
Oregon in 1969. Plant characteristics and yield components studied
included plant height, ear height, number of ears, ear weight...
The sudden failure of metal structures under load, which has
been a design problem for many years, is characterized by a crack
propagation rate which approaches the speed of sound in the material.
These failures, which are often known as catastrophic fractures,
may be divided into two types which depend...
The mechanical properties of materials at cryogenic temperatures
have been the subject of increasing interest during the past few
years, although very little actual materials testing has been done at
extremely low temperatures because of the high cost and low heat of
vaporaization of liquid helium. Recently, the Department of...
The response of three-dimensional frames subjected to an arbitrary
dynamic force is studied. The method of mode superposition
is used to obtain the frame response solution. Two different modeling
systems are used to idealize the frame. These are the "discrete
mass system" and the "continuous mass system." For an example...
Thirty-six gilts were used in an experiment of 2³ factorial
design. The experiment consisted of two breeds (Yorkshire-
Berkshire and Yorkshire), two feeding regimens (pre-breeding and
post-breeding) and two levels of dichlorvos (2, 2-dichlorovinyl
dimethyl phosphate, 0 and 800 mg. per gilt per day). Pre-breeding
treatment consisted of feeding dichlorvos...
