Abstract Freshwater salinization is a common yet underappreciated environmental problem in rivers, how this process impacts the transport of dissolved oxygen (DO) hyporheic zone remains unknown. Using flume experiments and numerical simulations, we have demonstrated that morphological dynamics DO transition are controlled by dimensionless number Da·Ra −2 , measure rate aerobic respiration to fr...

Abstract Anisakis is a parasite that found in many marine products and can cause anisakiasis when present fish consumed raw. The most common way to prevent freeze the fish, but this causes noticeable decrease quality of eaten as sashimi. Although no practical method killing anisakis other than freezing has been found, we have now succeeded inactivating inside meat by repeatedly instantaneously ...

In this paper we present a parallel implementation of a 2D numerical model for the solution of a transient density driven flow in porous media. The physical processes involved are multiscale, therefore computation time are usually long, thus a special effort has been made to speed-up computations by using parallel architectures. As most of the CPU time is spent in solving large sparse linear sy...

We investigated the relationship between glucocorticoids, thyroid hormones, and outer ring and inner ring deiodinases (ORD and IRD) during embryonic development in the saltwater crocodile (Crocodylus porosus). We treated the embryos with the synthetic glucocorticoid dexamethasone (Dex), 3,3',5-triiodothyronine (T(3)), and a combination of these two hormones (Dex + T(3)). The effects of these tr...

The global transfer of live bait creates a potent vector (mechanism) for invasion of marine species, including associated biota (“hitchhikers”) not intended for shipment. Unlike other vectors of non-native species transfer in coastal marine systems (e.g., ship ballast water), vector management strategies to reduce transport of associated biota with live bait are lacking. In this study, we exper...

Transitions from marine to freshwater habitats constitute dramatic shifts between 'adaptive zones' that have initiated the radiation and speciation of many taxa. As recently as 10?000 years ago, deglaciation resulted in marine fauna being trapped in freshwater lakes. In modern times, human activity has caused the acceleration of freshwater invasions from marine or brackish habitats, leading to ...

Infections associated with marine activities, particularly work or recreation in salt water, present unique diagnostic challenges for the infectious disease practitioner. Those caused by halophilic, non-cholera Vibrio species are increasingly being recognized in clinical practice. They typically follow saltwater injuries, especially those associated with coral. Because these infections can be b...
