Silvopasture is the planned and managed agroforestry system in which forage, livestock, and trees or shrubs are integrated in order to enhance individual components. Silvopasture has been identified as the most promising agroforestry system for the Pacific Northwest and Southeast United States. However, there have been few studies describing the...
Rural farmers in Tanzania depend on subsistence agriculture for their livelihood. Poor soil conditions, and the danger of drought, increases the risk of cyclical poverty conditions. Aid organizations, including the World Agroforestry Centre (ICRAF) and the Millennium Development Projects (MDP), as well as industrial tobacco industry, have provided development programs...
This thesis examines the interconnection between the in vitro and in
vivo phosphorylation of rabbit muscle phosphofructokinase. The first goal
of the project was to show whether a novel site of rabbit muscle
phosphofructokinase that is subject to in vitro phosphorylation, serine 376,
may also become phosphorylated in vivo. Evidence...
Humboldt Redwoods State Park in southern Humboldt County, California is a coastal redwood forest, a highly unique and valued ecosystem. It has many social, cultural, ecological, and economic values, including recreational benefits, heritage and aesthetic values, high biodiversity, nutrient cycling, and climate regulation. However, Humboldt County is at risk of...
This work describes a method for incorporating patient data into a nutrient transport model of the intervertebral disc.This data was collected using MRI diffusion weighted imaging (DWI), and was converted into an apparent diffusion coefficient map (ADC map). This map was used to define the diffusion behavior of water within...
The human intervertebral disc is a deceptively simple structure which plays an essential role in human movement. Even slight changes to the disc microenvironment can have far reaching consequences, particularly when these changes result in disc degeneration and herniation. Degeneration is increasingly tied to lower back pain; better understanding this...
The taste qualities of acidulants have not been studied in detail despite
the fact that they are widely used by the food industry. Studies on
characterizing the sensory properties of organic and inorganic acids are very
limited. Reported studies are commonly on threshold, equi-sour and the time
intensity values of...
With women comprising nearly 50% of HIV/AIDS infections globally, the development of new woman-initiated HIV prevention methods has become a public health imperative. To date, the female condom and the diaphragm are the only woman-initiated prevention methods available on the consumer market. Recent research has focused on two HIV/AIDS prevention...
To study the combined effects of seedling quality and fertilization at the time of planting, three experiments were established in western Oregon during the winter of 2000. The first experiment investigated the effect of preplanting rootvolume and fertilization rate on the field performance of 1+1 Douglas-fir seedlings during two growing...
Methane derived authigenic carbonate (MDAC) precipitation occurs within marine sediments as a byproduct of the microbial anaerobic oxidation of methane (AOM). While these carbonates form in chemical and isotopic equilibrium with the fluids from which they precipitate, burial diagenesis and recrystallization can overprint these signals. Plane polarized light (PPL) and...
