Stale flavor development has been recognized as a defect of
stored dry milk powders for several years. Recently, stale flavor
development has been found to occur upon storage of sterilized concentrated
milk, and is recognized as the principal limiting factor to
commercial utilization of this process (Seibert, 1963).
Some attempts...
This investigation was designed to determine the extent to
which students who are completing planned curricula in science education
are proficient in aspects of critical thinking, and possess
understandings of science consistent with those of the practicing
scientist. The effects of science curricula upon the development of
these abilities and...
Deterioration of the flavor of sterilized concentrated milk (SCM)
is recognized as the principal limiting factor to commercial acceptance
of this product. Although a number of volatile compounds have
been identified in SCM, quantitative information on these compounds
is lacking. It is therefore difficult to ascertain the significance of
these...
This study was designed with two major aims. The first was toexamine certain characteristics of both Departmental and Non- Departmentalteachers who were teaching matriculation chemistry in SouthAustralian secondary schools during 1967. The numbers of teacherswho participated were: Departmental 40, and Non - Departmental 23.The second was to ascertain certain learning...
This work has the purpose of presenting an approach to attitude
control applicable for sun alignment on scientific payloads.
As a primary source of information in order to obtain the alignment
error signals, four solar cells are disposed about the body of
the payload. As a secondary source a pair...
The ability of mercury to inhibit β - galactosidase activity from
cell-free extracts of Streptococcus lactis, Escherichia colt and
intestinal homogenates of hogs, female rats, and humans was studied. Mercuric acetate was added in vitro to all sources of β - galactosidase except for the rats, which were placed on...
The purpose of this descriptive research was twofold: 1) to
determine the expressed concerns, feelings, and needs of a selected
group of expectant fathers; and 2) to categorize those expressed
concerns, feelings, and needs into broad areas and to develop a
priority listing of those items as a basis for...
