Unity Reservoir in Baker County, Oregon, was chemically treated with liquid rotenone on October 17, 1962. Approximately 136 miles of streams and diversion ditches and seven small ponds, tributary to the reservoir, were treated with liquid rotenone prior to work on the reservoir. The reservoir at time of treatment contained...
Miller Lake was chemically treated with toxaphene on September 16, 1958 to destroy a population of parasitic lamprey (E.tridentatus) and Tui Chub (Siphatelep bicolor). Toxaphene was applied at the rate of 0.04 ppm. No lamprey or fish have been collected in the lake since the chemical treatment. Work since 1959...

This text was written for the purpose of explaining the use of the engineer's transit, theodolite, engineer's level and plane table in the solution of fundamental problems related to Forest Engineering. While the use of the infrared and electronic distance measuring instruments do have a place in Forest Engineering, they...
Non-coding ribonucleic acid (ncRNA) is of interest for its diverse roles in cell and viral biology. RNA molecules vary greatly in terms of size, structure, and function. In recent years, the modification of existing RNA structures has been used for biochemical methods of enormous impact including CRISPR and RNAi methods....
Premature birth interrupts the typical development of the human fetus, leaving the infant born with underdeveloped gastrointestinal and immune systems. Preterm infants have reduced stomach acidity, reduced digestive protease activity, more permeable intestinal membranes, impaired innate and adaptive immune response, and poor microbiome development. Due to these factors, preterm infants...
