Stability of normal quantum-fluid mixtures [PDF]
Laser Phys. Lett. 19 (2022) 103001, 2022 Mixtures of quantum fluids, that is gases or liquids, are considered with the emphasis on the conditions characterizing the stability of the mixtures. The mixtures, that can be formed by cold atoms or molecules, are assumed to be quantum requiring the description using quantum techniques, but not so cold that to exhibit superfluidity or ...

Effect of duration of stratification on growth and chemical properties of Ash (Fraxinus excelsior L.) [PDF]
تحقیقات جنگل و صنوبر ایران, 2017 Cold stratification is widely used to break dormancy of ash (Fraxinus excelsior L.) seeds. In this study, two groups of seedlings produced by two treatments of ash seeds, one and two-years cold stratification of seeds were investigated with three ...

New insight into stratification of anaerobic methanotrophs in cold seep sediments [PDF]
FEMS Microbiology Ecology, 2011 Methane seepages typically harbor communities of anaerobic methane oxidizers (ANME); however, knowledge about fine-scale vertical variation of ANME in response to geochemical gradients is limited. We investigated microbial communities in sediments below a white microbial mat in the G11 pockmark at Nyegga by 16S rRNA gene tag pyrosequencing and real ...

Effects of atmospheric cold fronts on stratification and water quality of a tropical reservoir: implications for aquaculture [PDF]
Aquaculture Environment Interactions, 2017 Stratification and mixing patterns of a water body are influenced by the variability of atmospheric systems, which can also modify their biogeochemical properties. The primary goal of this study was to analyze the effect of atmospheric cold fronts (CFs) on thermal stratification and water quality parameters in 4 embayments of the Furnas Hydroelectric ...

Cold-Moist Stratification Improves Germination in a Temperate Terrestrial Orchid [PDF]
Castanea, 2016 ABSTRACT Seed dormancy is a common evolutionary adaptation in temperate plant taxa. Dormancy mechanisms can prevent seeds from germinating at inopportune times, such as a cold period. We report the influence of pregermination stratification treatments on in vitro seed germination and seedling development in Platanthera chapmanii, a rare temperate ...

The Role of Wet Processes in Extratropical Thermal Stratification During the Glacial Period
Geophysical Research Letters, 2023 In this study, we differentiate wet processes from dry processes in shaping the extratropical thermal stratification during the Last Glacial Maximum. Our findings indicate that even during the dry glacial period the influence of wet processes on thermal ...

Stratification requirements for seed dormancy alleviation in a wetland weed. [PDF]
, 2013 Echinochloaoryzicola(syn.E. phyllopogon) is an exotic weed of California rice paddies that has evolved resistance to multiple herbicides. Elimination of seedlingsthroughcertain weed control methods can limit the spread of this weed, but is contingent on ...
