Estimation of genetic-parameters in the Oregon State University Hazelnut (Corylus avellana L.) breeding population

Creator:: Yao, Qiang
Abstract:: Heritability in the narrow sense and in the broad sense, variance components and correlation coefficients are important genetic parameters in a breeding program. The estimates of these parameters can provide important information for a breeder in the selection of parents, the most efficient design for evaluation of seedlings and advanced...

Wirelessly Powered cm-Scale Sensor for Small Insect Localization Application

Creator:: Kang, Jian
Abstract:: The prevalence of Internet-of-Things (IoT) applications leads to an increasing focus on the design and optimization of sensor nodes. Battery lifetime and associated costs of battery replacement often limits the long term operation and viability of sensor nodes. RF wireless energy harvesting on the other hand can be appealing since...

Boundaries of research : civilian leadership, military funding, and the international network surrounding the development of numerical weather prediction in the United States

Creator:: Harper, Kristine C.
Abstract:: American meteorology was synonymous with subjective weather forecasting in the early twentieth century. Controlled by the Weather Bureau and with no academic programs of its own, the few hundred extant meteorologists had no standing in the scientific community. Until the American Meteorological Society was founded in 1919, meteorologists had no...

Effects of irrigation and nitrogen on cauliflower development, yield and quality

Creator:: Bratsch, Anthony D.
Abstract:: Field experiments were conducted with cauliflower (Brassica oleracea var. botrytis cv. Snowball Y ) to determine crop development, yield, quality and maturity response to various seasonal water levels, and to specific water stress timing in relation to curd initiation. The effects of nitrogen rate, timing, and source and the application...
