The effects of hydrogen sulfide (H2S) on storage quality, cellular water distribution, and cell wall metabolism of strawberry fruit after subjected to shelf or cold storage were investigated. Fruit were fumigated with a range of aqueous NaHS solution (0.4-3.2 mmol/L), then stored at 20 degrees C for 3 d or...
This study was to determine whether postharvest hydrogen sulfide (H2S) fumigation effected surface pitting development of 'Lapins' and 'Regina' cherries after cold storage, and if so, how it minimizes surface pitting injury and its relation to cell wall metabolism. Fruit were exposed to H2S gas released from an aqueous solution...
The uptake of hydrogen by lanthanum pentanickel (LaNi₅) to form lanthanum nickel hydride (LaNi₅H₆) is
followed with three-dimensional imaging by neutron tomography. The hydrogen absorption process is
slower than the time needed for acquiring a single radiograph, about 10 s, but fast relative to the time
to acquire a fully-sampled...
The volume and complexity of their vascular systems make the dynamics of long‐distance water transport in large trees difficult to study. We used heat and deuterated water (D₂O) as tracers to characterize whole‐tree water transport and storage properties in individual trees belonging to the coniferous species Pseudotsuga menziesii (Mirb.) Franco...
Industrial emissions of SO₂ and NOₓ, resulting in the formation and deposition of sulfuric and nitric acids, affect the health of both terrestrial and aquatic ecosystems. Since the mid-late 20th century, legislation to control acid rain precursors in both Europe and the US has led to significant declines in both...
Solar thermochemical energy storage has enormous potential for enabling cost-effective concentrated solar power (CSP). A thermochemical storage system based on a SrO/SrCO₃ carbonation cycle offers the ability to store and release high temperature (≈1200 °C) heat. The energy density of SrCO₃/SrO systems supported by zirconia-based sintering inhibitors was investigated for 15...
Internal browning (IB) can be a serious problem with the use of modified atmosphere packaging
(MAP) for 'Bartlett' pears (Pyrus communis L.) grown in the Pacific Northwest during storage
and transit to distant markets. To investigate this disorder, 'Bartlett' pears harvested at
commercial maturity were packed in a commercial MAP...
Stable isotopes can be a valuable tool for tracing the redistribution, storage, and evaporation of water associated with canopy
interception of rainfall. Isotopic differences between throughfall and rainfall have been attributed to three mechanisms:
evaporative fractionation, isotopic exchange with ambient vapor, and temporal redistribution. We demonstrate the potential
importance of...
Most sweet cherries produced in the US Pacific Northwest and shipped to distant markets are often in storage and transit for over 3 weeks. The objectives of this research were to study the effects of sweet cherry storage O2 and CO2 concentrations on the respiratory physiology and the efficacy of...
This research focuses on biochemical changes related to quality losses observed in Atlantic mackerel (Scomber scombrus) muscle stored under commercial frozen storage conditions (9 months, -18 ºC) when subjected to high-hydrostatic pressure (HHP) treatments (125, 150, 175 and 200 MPa for 0 min) before freezing. After freezing, free fatty acid...
