There are about 80 million single-family dwellings (SFDs) in the United States, predominantly of wood-frame construction. Of these, 68% are owner-occupied. A home is typically the largest single investment of a family, and is often not covered by earthquake insurance, even where it is available. Of all the houses in...

A commercially available, three-dimensional finite-element analysis software was used to model the load-displacement
behavior of metal-plate-connected (MPC) joints in wooden trusses. Model features included consideration
of material properties, teeth-to-grain-to-direction-of-force orientation, wood-to-wood interaction, and gaps between wood
members. To simulate wood-to-plate interaction, the main feature of the model, each tooth of...
"This publication has presented an overview of current research on MPC joints in wood trusses. The literature search was primarily of U.S. sources, with some effort to obtain literature from other parts of the world. An enormous amount of important information has been amassed by studies on testing procedures and...
The level of polymorphisms of many biochemical and DNA markers are low in
cultivated sunflower (Helianthus annuus L.). The number of mapped public DNA
markers is limited. Molecular markers have not been developed for the most
important diseases of sunflower, such as downy mildew. The objectives of this
study were...
The objective of this study was to examine vegetation and vegetation change in Eritrea over a period from the mid 1980s to 2002 using satellite remote sensing, and relate observed changes to the recent history of drought and war in the region. Specific objectives were (1) to examine vegetation change...
The objective of this research is to use a three-dimensional (3D) analysis
method to include 'system effects' directly in the design of light-frame roof truss
assemblies. The goal of this study is to develop an improved and practical method to
determine the structural performance of 3D roof truss assemblies used...
Ecological impacts of climate change in the Pacific Northwest may hinge on acclimation to drier summers, highlighting the importance of plant physiological studies in forests. Evaluating dominant forest plant species under old-growth and managed forest conditions is similarly important as timber harvest might change microclimates and alter drought effects on...
Agrivoltaic systems promote dual use of land by combining solar energy and agricultural production. Grazing sheep in these systems is popular but research on intentionally designed pastures to increase production is lacking. This study seeks to compare the herbage growth and lamb production in simple, diverse, and legume pasture mixes...
This study examines the association of household characteristics with forest product consumption and other benefits derived from community forest in Nepal. The analysis is based on random sample data of 80 households from a Community Forest User Groups of Baghmara Community Forestry (BCF) in Nepal. Using an OLS regression to...
