Due to public and regulatory restrictions, genetic containment technology is critical for research and development of transgenic trees in forestry. A multi-year field trial demonstrated that the RNAi-LFY construct successfully induces sexual sterility in 6K10 poplar (Populus alba) without visible effects on vegetative development. However, its limited number of replicates...
Successful ecosystem restoration requires an understanding of the ecological processes directing succession. One of the challenges in the semi-arid grasslands of western United States is replacement of native species by invasive annual grasses. Solutions to this problem require identifying and manipulating ecological processes that direct succession to favor desired vegetation....
The purpose of this study is to develop an analytical framework for identifying and evaluating conditions that precipitate currency devaluation like those experienced by Mexico in 1994. This study develops a framework of financial and macroenvironmental indicators that point to potential currency devaluation in the future. Some of these indicators...
Improving the methods used for the detection and estimation of fissile material mass content is essential to nuclear security and safeguards to ensure special nuclear material (SNM) accountability, control, safety and security. With the continued expansion of the nuclear industry and the need for safe management of spent fuel, improving...
At present all vaccines for fish are primarily delivered either by injection or immersion which introduces added stress and labor. A more attractive method of vaccine delivery is oral administration using an enteric protection system, Enteric Coated Antigen Microspheres (ECAMs), which can be utilized for a variety of antigenic forms....
The conservation of open space will become increasingly important as populations expand and undeveloped land is converted to urban uses. The benefits derived from open space conservation include protecting and improving water quality, providing wildlife habitat, maintaining scenic amenities and rural character, and supplying certain recreational opportunities. This study utilizes...
Acidity distribution within any given soil profile is dependent on
mineralogical make-up of the parent material as well as environmental conditions prevalent during the weathering history of the soil.
An experiment was designed to study the distribution pattern of exchange acidity, exchangeable aluminum, exchangeable manganese and
pH of six acid...
Himalaya blackberry (Rubus armeniacus) is a widespread, exotic, invasive plant now common over much of western Oregon and Washington. An observational experiment revealed that disturbance to a monoculture of Himalaya blackberry allows the soil seed bank to be expressed and return the inhabited area to an earlier successional stage. This...
Immunological memory has been shown to occur
unequivocally in mammals. However, controversy exists regarding
the capability of fish to elicite a memory response. This study
demonstrates that memory does occur
rainbow trout, Oncorhynchus rnykiss.
Trout injected with a T-dependent antigen,
trinitrophenylated keyhole-limpet hemocyanin, (TNP-KLH) (100
μg/fish) were able to produce...
