The need to replace the present methods of rating the acceptability of a manufacturer's lot of strawberries is indicated. Work has been done towards adapting and developing laboratory techniques for this purpose.
The quality factors checked upon were the state of maturity, the effectiveness of processing work, and the freedom...
Equipment and technology suppliers to the US forest sector are confronting challenges and opportunities to meet the need for disruptive changes in an increasingly complex business environment. Open innovation is crucial for survival and success in the complex and changing operational environment due to its inherent openness and interdisciplinary nature....
The United States (US) Department of Energy (DOE) has identified the pebble-bed reactor as a high priority for US research with the end goal of licensing a pebble-bed reactor (PBR) for operation in the United States. Before this can be accomplished significant research must be done regarding the safety of...
The High Temperature Test Facility (HTTF) is an electrically heated, scaled model of a Modular High Temperature Gas Reactor (MHTGR). Five experiments were conducted to study Depressurized Conduction Cool-Down phenomena stemming from a Double-Ended Guillotine Break (DEGB). After a DEGB, the reactor pressure vessel would depressurize until the pressures are...
Sodium cooled nuclear reactors are being considered for the next generation of nuclear power plants to provide clean electricity to the world. To prove the safety of these reactors, the fuel must be shown to safely handle large neutron fluxes that cause a spike in the thermal output of the...
Wicking action refers to the movement of a liquid through a porous or a structured surface via capillary action. This phenomenon is affected by surface geometry, such as the wick thickness and pore size of the wick, as well as fluid properties, such as viscosity and surface tension of the...
This thesis presents an experimental study of radial porosity in a manually filled cylindrical container with glass spheres. The symmetric distribution of bead diameter allowed for normalization of container properties and porosity models. The aspect ratio of the container was approximately 3.9, with tube-to-particle-diameter ratio λ ≈ 24.6 and height-to-particle-diameter...
Synthetic adhesives like phenol formaldehyde (PF) and isocyanates dominate the
wood based structural panel market. The raw materials that makeup these adhesives
are based on petroleum and natural gas. The sustainability and the continued success
of the wood based structural panel industry will benefit from the development of
alternative adhesives...
Oregon State University has recently conducted a complete core conversion analysis as part of the Reduced Enrichment for Research and Test Reactors Pprogram. The goals of the thermal hydraulic analyses were to calculate natural circulation flow rates, coolant temperatures and fuel temperatures as a function of core power for both...
