Approximately 3-4 month-old containerized Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings (seed zone 262 and 271) were subjected to 6 moisture stress treatments (65, 53, 41, 29, 17 and 7% soil water content by volume of dry soil) starting July 4 to September 22, 1991 at Forest Research Laboratory's greenhouse at...
Experiments were conducted to determine if the plagiotropic
growth habit of rooted cuttings of Douglas-fir might result from a
system favoring the accumulation of indoleacetic acid in the adaxial
side of the shoot in response to vertical placement.
Actively growing excised branch terminals were subjected to
gravitational disorientation to determine...
A full range of experiments was carried out to investigate the
effects of environmental factors on the terminal bud dormancy in two
high-elevation true fir species, Shasta red fir (Abies magnifica A.
Murr. var. shastensis Lemm.) and noble fir (A. procera Rehd.),
seedlings. Photoperiod, thermoperiod and moisture stress were of...
The purpose of this study was to analyze the state of development of
adult education in Nigeria.
The major objectives were to review the state of development of
Nigerian adult education programs, assess the overall effectiveness of
these programs, and utilize the findings to suggest action for future
program improvement....
The Grant Range, in east-central Nevada, is a
north-east trending range bounded on the west by a
west-dipping normal fault system. Rocks within the range
record a complex polyphase Mesozoic ductile
compressional and Cenozoic brittle extensional
deformational history. The northwestern Grant Range
exposes deformed, regionally metamorphosed and
unmetamorphosed, Cambrian to...
Theoretical derivations to describe pan evaporation, E[subscript p], and evapotranspiration, ET[subscript r], were developed based on a flow equation expressed as the product of the driving force for vapor between the evaporative surface and a plane of reference times a conductivity coefficient of vapor through air. Under the assumptions of...
According to Wang and Repetti (2013), American adults are working more hours per week than in decades past. Additionally, more people in each family must work to support their families (Patten, 2015). This has led to an increase in stress levels due to the strain that is placed on balancing...
The gut microbiome influences human disease including Type 2 diabetes, obesity and metabolic syndrome and interacts with the innate immune system. The human cathelicidin antimicrobial peptide (hCAMP), an important component of the innate immune system, and vitamin D and xanthohumol, a natural compound found in beer hops, regulate its expression....
The degree to which camping is related to selected characteristics of river terraces along the Rogue Waterway, Oregon has been analyzed. Previous attempts to formulate models relating campsite choice to characteristics of the natural environment focused on camping parties engaged in auto-camping and the aggregate population behavior rather than on...
