Microbial natural products represent a massive repository of unique chemical scaffolds with corresponding diverse biological functions. However, in the past decade the development of natural products into new therapeutics has dwindled, in part due to the challenges posed by high rediscovery rates and low throughput associated with classical bioassay-guided fractionation...
Large numbers of reinforced concrete deck girder (RCDG) bridges were built during the highway infrastructure boom of the 1950's. The advent of standardized deformed steel reinforcing bars during this time allowed for straight bar terminations in flexural tension regions. Designers of the time terminated reinforcing bars where they were no...
For many years, engine overhearing has been the major cause for vehicle breakdowns and engine malfunctions for most teams in Endurance events at Formula Society of Automotive Engineers (FSAE) Series competitions. Additionally, with a growing importance of aerodynamics to the overall success of the Global Formula Racing at these events,...
The well-known local adjustment algorithm for training a
threshold logic unit, TLU, is extended to a local adjustment
algorithm for training a network of TLUs Computer simulations
show that the extension is unsatisfactory.
A new logic for a committee of TLUs, called modified veto logic,
and a local adjustment algorithm...
The exchange of carbon on earth is one of the fundamental processes that sustains life and regulates climate. Since the onset of the Industrial Revolution, the burning of fossil fuels and anthropogenic land conversion have altered the carbon cycle, increasing carbon dioxide in the atmosphere to levels that are unprecedented...
A potato plant growth and production model is developed with
the objectives of analyzing management alternatives and exploring
the nature of the early dying syndrome. The geographic area of
focus was the centerpivot irrigated circles of Oregon's Columbia
Basin. A problem analysis of the potato production system of this
area,...
Copper sulfides (Cu[subscript x]S) are compound semiconductor materials that exhibit considerable optical and electrical properties varying significantly as a function of the composition. Copper sulfide thin films can be used in many applications, such as solar control coatings, solar cells, photothermal conversion of solar energy, electroconductive coatings, and microwave shielding...
The high resolution stimulated Raman spectrometer at OSU was
modified to improve its sensitivity and to extend its range of
applications to low Raman shifts and to the spectroscopy of solids and
liquids. As part of the characterization of the spectrometer, optical
Stark effects on rotational and vibrational transitions of...
