Conversion of solar energy to mechanical power through the use of
thermostatic bimetals and linear Fresnel lenses was found to be both
theoretically and experimentally feasible. Using linear Fresnel lenses
to concentrate sunlight on bimetallic coils caused a simple sun powered
motor to produce rotational shaft power. However, continuous rotational...
The assumption of constant quartz accumulation for the deep-sea

Glutenin protein molecules can form a large "macropolymer" which forms the elastic component of the gluten complex in wheat flour doughs. Little work has been done to investigate relationships between glutenin macropolymer (GMP) and noodle processing. GMP was isolated from flour of 4 wheat varieties; 3 hard- and 1 soft-grained...

The hemlock woolly adelgid, Adelges tsugae, is causing widespread mortality of eastern hemlock, Tsuga canadensis, in the eastern United States. In the West, A. tsugae causes negligible damage to western hemlock, Tsuga heterophylla. Host tolerance traits and presence of endemic predators may be contributing to the relative tolerance of western...

Barley (Hordeum vulgare L.) is one of the oldest known domesticated crops. Originally cultivated for human consumption, other end-uses have gained importance over the millennia. Barley is the fourth most important cereal crop in the world (FAO-STAT, 2011), and today it is mainly used as animal feed or malted for...
Plant pathogens in the genus Phytophthora are known to cause disease on field crops, nursery plants, and forest trees. The best known example probably is Phytophthora infestans, which triggered the infamous Irish potato famine. Other important Phytophthora species include: P. ramorum (sudden oak death pathogen), P. sojae (soybean root rot...
Understanding complex traits is a fundamental challenge in plant genetics and a prerequisite for molecular breeding. Tools for trait dissection are markers, maps, and quantitative trait locus (QTL) analysis. Marker-assisted selection (MAS) is an application that integrates these tools. In this thesis research, a new sequence-based marker was evaluated, maps...

Kernel hardness (KHA) is a major factor determining break flour yield (BFY) and end-use quality of common wheat (Triticum aestivum L.). Within the soft wheat class, genotypes with consistently softer grains than common soft wheat are considered to be 'extra-soft'. In addition, 'extra-soft' wheats have greater BFY than common soft...
