Forest landowners are interested in practicing alternative silviculture methods on their property without having to clearcut. This publication describes a case study on shelterwood harvest and two-aged stand management of a forest in the Oregon Coast Range. The landowner’s core management philosophy is to create forests that are both ecologically...
This publication is offered as a reference to Integrated Pest Management (IPM) resources available to Oregon growers. It highlights university, federal, state, and private services and resources that provide support to growers in the implementation of IPM programs. The Guide consists of five sections: • An introduction to the National...
The purpose of this work was to develop a dynamic partial order model of II electrolyte solutions which avoids inconsistencies present in the Debye-1-Iuckel and 1n related theories. It is shown that our results are consistent with activity coefficient data in aqueous electrolyte solutions. The main features of our work...
The major purposes of this study were (1) to construct a reliable and
valid scale for measuring writing self-efficacy levels in adult basic education
students, (2) to further test the scale's validity and reliability by administering
it to a second selected group of adult basic education students, and (3) to...
Ecosystems are highly heterogeneous systems subjected to important levels of environmental variability; however, it is common in terrestrial biogeochemical models to assume homogeneous properties of the elements of the system or constant environmental conditions. For some processes, heterogeneity in these models is treated very simplistically, but there is not much...
The development of a novel high temperature space radiator is
described. A Rotating Bubble Membrane Radiator (RBMR) combines the
best features of heat pipes and droplet radiators while avoiding
their negative attributes. The RBMR offers light weight, self
deployment, ease of startup and its performance is less affected by
acceleration....
