This project describes the investigation of marine cyanobacteria collected from the Red Sea with an emphasis on the identification and prioritization of biologically active fractions for future purification and molecular structure elucidation of medicinally relevant secondary metabolites.
Five crude extracts of taxonomically unidentified Red Sea cyanobacteria supplied by Egyptian collaborators...
On July 9th, the Pacific Marine Energy Center (PMEC) and PacWave hosted national and international experts from government, academia and industry, and across maritime sectors, to explore future research and testing opportunities associated with the development of the PacWave testing facilities. This report summarizes the findings from the strategic break-out...
Qualitative two-phase flow regime data are obtained from high-speed visualization of condensing flows of R-134a at mass fluxes from 75 to 150 kg m−2 s−1 and quality from 0.1 to 0.8 in square microchannels (DH = 0.84 mm) cooled from a single side. Superheated R-134a is distributed into multiple parallel microchannels and then partially condensed, using...
Concentrated solar power (CSP) plants have the potential to provide 24 h, renewable electricity. Current CSP systems have high capital and operational costs which makes the levelized cost of electricity uncompetitive with conventional techniques. Recent experimental research has shown the potential of small unit cells (up to 2 × 2 cm) containing micropin arrays...
The advancement of additive manufacturing enables significantly greater freedom of design compared to conventional techniques. Of significant interest is the potential improvements in the design of cold plates and heat sinks for electronics cooling. Greater design freedom could enable new designs that reduce thermal resistance and hydraulic resistance, enabling the...
Membrane based heat pumps systems have attracted the attention of many research groups as a potentially more environmentally friendly alternative to vapor compression systems for space cooling. Several prototype systems have been developed, with reported claims of Energy Efficiency Ratios (EER) approaching 26. At present, no detailed analysis is publicly...
In climate regions with large seasonal variations in solar radiation, such as the Pacific Northwest of the United States, a solar thermal energy collector might not economically satisfy year-round domestic water heating demands, requiring an auxiliary unit, such as a natural gas-fired water heater. Previous studies have shown that the...
Supercritical carbon dioxide (sCO2) experiences a drastic change in its thermophysical properties near the thermodynamic critical point. A non-linear thermophysical property variation can influence the heat transfer behavior of sCO2 which is not predicted well by conventional single phase heat transfer theory. This can become a major hindrance in the...
There is growing interest to use supercritical carbon dioxide (sCO2) as a working fluid in thermal management applications. This study investigates the thermal-hydraulic performance of microchannel heat sinks as a function of flow channel geometry and orientation at operating conditions representative of electronics cooling applications. Three different experimental test sections,...
Peppermint residue consists of the cooked leaves and stems of the peppermint plant after high-temperature distillation to extract oil. This residue has value as a soil amendment. It is often applied to fallow fields in the fall or sold as a soil amendment to gardeners. Research was conducted to determine...
The goal of this project was to estimate the total annual cost of salmon recovery efforts throughout the Columbia River Basin from all stakeholders, including direct and indirect costs. How much is spent on salmon recovery efforts each year in the Columbia River Basin? Depending on who you ask, you...
Contaminants in stormwater such as heavy metals, PFASs, PCBs, and PAHs are an issue for public infrastructure and remediation practices. Biochar, granular activated carbon (GAC), OGSIR soil, and commercial adsorbent materials have been evaluated with the heavy metals Cu2+ and Zn2+. Copper and zinc as stormwater contaminants were treated with...
Skin condition assessment of wildlife can provide insight into individual and population health. Yet, logistics can limit skin condition assessment of large whales. We developed a standardized, quantitative protocol using photographs to assess skin condition of blue whales in New Zealand, and demonstrate the value gained by testing hypotheses, documenting...
Sablefish is a highly sought after seafood delicacy for which aquaculture of this species has recently been developed. By understanding the immunological functions in sablefish, our goal was to develop a mammalian fluorescent bioparticle assay that can viably analyze the efficiency of phagocytosis, an important function of the immune system....
