The leaf- cutter bee Megachile rotundata (Fabricius) is an important
alfalfa pollinator in western North America.
This study was designed to provide information on methods of
orientation used by M. rotundata in order to make recommendations
regarding the parameters within which adult nesting populations may
Preliminary studies suggest...
The study provides the details of the ethology of Megachile rotundata
(Fabricius), and presents preliminary observations on its
foraging and nesting behavior. Development from prepupae to adults
proceeds most rapidly at 32 degrees C., and is retarded when held
at lower and higher temperatures.
Male behavior is distinct from that...
The objectives of this study include an attempt to determine what broad fields of education are most essential to the welfare of Orissa in the light of her intense current problems. It must suggest definite goals and areas for study by the adults of the province. Some development of the...
This study investigated the effect of first aid instruction on
college students' attitudes toward safety. It evolved from previous
studies of the relationship between first aid and accidents in Canada
and the United Kingdom. These earlier studies were concerned with the
effect of first aid training on accident rates. The...
The purpose of this investigation was to modify the procedure
of Bills, Khatri and Day for use in the development of a suitable
method for determining the quantitative distribution of the free fatty
acids (FFA) in normal, heated, and rancid milk and milk fractions
The method consists of extracting the...
The free fatty acids of milk fat are believed to be involved in
imparting flavor properties to milk and other dairy products. In the
past the free fatty acids have largely been related to quality deterioration
and hence the methods for measurement have been devised to
determine the changes in...
Numerous investigations have been made on the contribution of
butter cultures to the flavor of cultured cream butter, but production
of uniform cultured cream butter has not been possible in industry.
Therefore, it was desirable to investigate in detail the qualitative
and quantitative chemistry of the flavor of high quality...
The use of the exponential-transfer-characteristics of a transistor
junction as a means of giving a logarithmic sweep calibration to a
sampling oscilloscope is presented. The prior work in logarithmic
converters leading up to the use of the transistor's transfer properties
is explored. A circuit adapting a sampling oscilloscope to a...
