Melanocytes are dendritic, pigment-producing cells located in the skin and are responsible for its protection against the deleterious effects of solar ultraviolet radiation (UVR), which include DNA damage and elevated reactive oxygen species (ROS). They do so by synthesizing photoprotective melanin pigments and distributing them to adjacent skin cells (e.g.,...
The literature defines a displaced homemaker as a
woman who has worked primarily without remuneration to
care for the home and family (U.S. Congress, 1977).
Federally funded displaced homemaker programs are
provided to help these women move from dependency to
self-sufficiency (Displaced Homemakers Network, 1986).
The purpose of this study...
This study documented the history of the development and practice of the
kinlein associate. Consumer dissatisfaction with health care, nursing unrest, and
increased demand for long-term care-givers were the antecedents for a paradigm shift
to "caring with" persons based upon the theory of esca developed by
M. Lucille Kinlein. Interested...
Purple nutsedge [Cyperus rotundas L.) has been recognized as one of the
most troublesome perennial weeds of agricultural lands in tropical and some
temperate regions. This research sought to determine the effects of timing of
herbicides, shading, and soil moisture on plant population growth and tuber
production of purple nutsedge...
This thesis concerns the alteration of the course of selective
protein synthesis and morphogenesis in plants treated with growth
regulating chemicals. Treatment of 48-hour-old "Alaska" pea seedlings
(Pisum sativum L.) with 2, 4-D, IAA, NAA or picloram caused
inhibition of epicotyl and primary root elongation and proliferation of
massed lateral...
The energy absorbed by microscopic volumes exposed to ionizing
radiation is not well represented by the average dose due to the small
number of discrete energy transfers involved. The energy deposited in
a microscopic volume can be determined by measuring the ionization in
a detector filled with gas at low...
Methane flux was measured from northern Alaska Arctic Coastal Plain wetlands to assess the spatial and temporal variability of Arctic tundra emissions during the summers of 1987 through 1990. Initially, the role of vegetation in the release of methane from substrate to atmosphere was assessed. Methane emissions were shown to...
This phenomenological inquiry explored dimensions of reflection for older adults in a developmental oriented adventure education experience. Data were gathered from emergent interviews with four individuals while participating in a multi-day, self-contained experiential education program conducted in a rugged environment, and led by a Navajo leader. Two principle research questions...
