Complementary delta-doped AlGaAs/GaAs Heterojunction Field Effect Transistor
(CHFET) devices and circuits were fabricated using MBE and a 2μ non-planar gate
recess process. Several schemes were used in an attempt to improve the performance of
the p-channel HFETs. These included delta-doping, carbon-doping and dipole-doping.
Circuits and individual n- and p- channel...
Contemporary parenting strategies tend to involve
parent-child interactions in which the parent neither
repressively dominates the child nor follows a permissive
laissez-faire course but respects the child's dignity as a
person. This paper integrates several current theories of
parenting and parent education into the construct of
"respectful parenting," which is...
Published literature about six Pacific Northwest stream systems was contrasted
to provide a regional perspective on channel response to disturbance. This
investigation was prompted by a combination of recent environmental legislation,
mounting social pressures to plan projects at a drainage basin scale, and the difficulty
in defining and predicting the...
This study compared the effect of two sources of instruction and verbal
encouragement on the participation of individuals with mental retardation (MR) in a 10-week physical activity program. Participants were 17 adult employees of a sheltered
workshop (5 females, 12 males) ranging in age from 30 to 65 years. The...
Calcium channel blockers (CCB) was studied extensively in cardiology for their tissue
protective effect following myocardial infarction; we hypothesized that administration of
a CCB would interfere with the processes that result in exercise-induced muscle damage
(EIMD) and delayed onset muscle soreness. To investigate the effects of a CCB on a...
Although research evidence clearly indicates support surface properties are a major factor contributing to fall risk among the elderly, investigations examining the influence of variations in surface conditions on the postural control of older adults during task performance have been limited. Thus, the primary purpose of the present studies was...
