The reproduction and mode of spread of sago pondweed (Potamogeton pectinatus L.) in irrigation system

Creator:: Ogg, Alex G.
Abstract:: Nine experiments were conducted during 1964 and 1965 to study the methods of reproduction and mode of spread of sago pondweed (Potamogeton pectinatus) in irrigation systems. Frequent treatments of sago pondweed foliage with aromatic solvent greatly reduced the number of tubers in the substratum of an irrigation canal. However, complete...

A transistorized sonic generator and detector for finding Young's modulus of wooden beams

Creator:: Jaenicke, Richard Alex
Abstract:: Young's modulus, often called the modulus of elasticity, gives a measure of the stiffness of a material to an imposed load. The modulus of a wooden beam is most often obtained by destructive tests which destroy the specimen. If a practical method can be found to measure Young's modulus non-destructively,...

Herbicide effects on Bdellovibrio bacteriovorus

Creator:: Wehr, Nancy Briggs
Abstract:: Bdellovibrio bacteriovorus is a small parasitic bacterium present in soil, mud, and aquatic habitats. Due to its lysis of Gramnegative bacteria, an important role in soil ecology has been suggested for this organism. A study of effects of herbicides upon Bdellovibrio might consequently be of considerable value. In this study...

Stimulation of plant growth by sub-lethal concentrations of herbicides

Creator:: Wiedman, Steven John
Abstract:: Studies were conducted to determine the extent and nature of sub-lethal effects of herbicides on plant growth. At least one herbicide from each major chemical class of herbicides was evaluated under greenhouse conditions. Oat plants were grown in sand culture to eliminate soil interferences. Herbicides were applied pre-emergence in nutrient...
