Development of a suitable thin-film technology has stimulated research in, and production of, a.c. thin film electroluminescent (ACTFEL) devices. The aim of this thesis is to provide a better understanding of the physical processes associated with the device characteristics
of such ACTFEL devices. The unique phenomena exhibited by these devices...
An experiment was conducted with 51 control and 51 experimental confinement-
managed purebred Yorkshire sows of various parities to (1) determine
whether confinement-managed sows during lactation would exhibit estrus,
mate, and conceive as a consequence of a daily regimen of a short period of
separation from their litters, mixing sows...
At weights of 81.5-90.5 kg, 187 prepuberal crossbred gilts were
subjected to specific environmental stimuli, for up to 17 days, to
determine which stimuli or combinations of various ones would initiate
onset of estrus in prepuberal gilts. The stimuli used were:
movement to new building, mixing or non-mixing of gilts,...
The investigations were based on a complete diallel cross
among three inbred lines of Suffolk sheep. Line of sire effects were
assumed to be an estimate of general combining ability effects while
sire x dam interaction was assumed to be an estimate of specific
combining ability. The line of dam...
It has long been recognized that fermented food products possess
a characteristic but pleasant flavor. The use of such foods, however,
has been limited by the presence of ethanol. Thus the objective of
this research was to investigate the possibility of producing non-alcoholic
fermented juice concentrates.
Three varieties of juices,...
The electrical properties of ion-implanted GaAs FET channels
are investigated by two methods. First, the channel current (I) as
a function of voltage (V) is examined at different temperatures and
using different voltage ramp rates. The standard FET I-V curve,
which can be observed on a commercial curve tracer, is...
As the CMOS process scales down to submicron, digital circuit performance improves, while reduced supply voltage and lower transistor intrinsic gain make it difficult to implement analog circuits in a power efficient manner. Therefore, it has become advantageous to shift more analog signal processing functions conventionally realized in voltage (analog)...
