There are a number of wood properties which affect the quality of forest products such as lumber and pulp. Of these, wood density is considered by some to be the single most important physical characteristic because it is an excellent predictor of strength, stiffness, hardness, and paper-making capacities. Accurately assessing...
Orchard floor management (OFM) practices can improve soil function and alter
the soil biological community. Soil function is dependent on soil forming materials and
on management practices but little is known about how OFM affect orchard soil quality,
fertilizer N uptake, or tree growth and production.
Research plots were located...
Growing societal demand for forest products is pressuring managers to increase productivity from a finite land area, and it is expected that increased supply will come mostly from expansion of intensively managed stands. The USDA Forest Service and numerous collaborators created the Long-Term Soil Productivity (LTSP) network of research sites...
Diverse stakeholders and land management agencies are increasingly working together in “forest collaborative” groups to meet ecological, economic, and social goals on Oregon’s public lands. Many collaboratives focus on science-based ecosystem restoration. One such group is the Deschutes Collaborative Forest Project (DCFP) in central Oregon, which seeks to increase forest...
Since the end of the Cold War, the US Navy has had an increasing interest in continental shelves and slopes as
operational areas. To work in such areas
requires a good understanding of ocean
acoustics, coastal physical oceanography,
and, in the modern era, autonomous
underwater vehicle (AUV) operations.
Each area...
Funds alloted from the Vocational Education Act of
1963, Public Law 88-210, opened up an entirely new dimension
in vocational agriculture programs throughout the
nation.
The new dimension is an amendment to the period
beginning with the Smith-Hughes Act in 1917. Up to the
time of the Vocational Education Act...
Respiratory illnesses caused by both viral and bacterial infection are serious issues for global healthcare providers. With the emergence of new, drug-resistant forms of these diseases, innovative drugs and treatment therapies are needed. M tuberculosis is an infection that affects a large portion of the world’s population each year. Aerosol...

The United States of America and the world are faced with three massive intertwining challenges at this time: COVID-19, racial inequity, and climate change. As a species, humans must come together and collectively address these challenges to preserve our humanity and make our world a more just and livable place...

Predators are fundamentally important for regulating and driving prey population dynamics as well as structuring ecological communities. Over-exploitation of marine resources has caused dramatic depletions of predatory fish species and shifts in marine community composition, with attendant declines in productivity and diversity of marine ecosystems. Despite the important ramifications of...
This capstone project is expected to be published by United States Department of Agriculture Animal and Plant Health Inspection Service Wildlife Services (USDA APHIS WS) as part of a technical series guide available to the public through the website (https://www.aphis.usda.gov/aphis/ourfocus/wildlifedamage/sa_reports/ct_wildlife+damage+management+technical+series). USDA APHIS WS is responsible for mitigating human-wildlife conflict and...
2,4,6-Trinitrotoluene (TNT) has been the common munitions used in the world and is an environmental contaminant that is amendable to reductive transformation reactions. The rumen is an extremely reductive environment containing diverse microbial populations. There are 21 pure culture ruminal bacteria species in culture collection, these were tested for the...
A study of the relative rates of the alkyl hydrogen abstraction
from a series of meta and para substituted t-butylbenzenes by the
chlorine atom at 70°C has been carried out. Application of the
Hammett equation yielded a ρ value of -0.44 for the para compounds.
Possible explanations for the non-linearity...
Includes 1922 Summer School Graduates.
In the following pages the information, so far as it has been possible to obtain it, is given in the following order for each alumnus: Name, year in which the degree was conferred, degree, course, present occupation, and present mailing address.
Focus is published by Oregon State University College of Forestry. Our goal is to keep Forestry alumni, friends, faculty, staff, and students informed about the College of Forestry and its many activities and programs.
A study of the relative rates of benzylic hydrogen abstractions
from a series of meta and para substituted neopentylbenzenes by the
bromine radical and trichloromethyl radical at 70°C has been carried
out. Application of the Hammett equation yields p values of -0.75
for the bromine atom and -0.94 for the...

Successful pruning relies on accurately identifying the 3D structure of tree branches and leaders. However, this task is arduous in an agricultural setting due to the complexity of scenes, the presence of clutter, and variable weather conditions. This project addresses these challenges by leveraging advancements in 2D image segmentation and...
