Kinetic Resolution with a Polymer-Supported Resolving Agent
When contacting an insoluble copolymer functionalized by (+)-alpha-methylbenzylamine with a resin-swelling solvent containing racemic mandelic acid, the fixation of acid in the solid phase is observed to be partial and stereoselective.

Abstract Anadromous Arctic char (Salvelinus alpinus) and northern form Dolly Varden (Salvelinus malma malma) are highly valued by Indigenous communities in northern Canada. Rapid, ongoing environmental changes are affecting populations of both of these iteroparous species, and understanding variability in life‐history tactics is essential for ...

Low regularity well-posedness for the one-dimensional Dirac-Klein-Gordon system
Local well-posedness for Dirac-Klein-Gordon equations is proven in one space dimension, where the Dirac part belongs to $H^{-frac{1}{4}+epsilon}$ and the Klein-Gordon part to $H^{frac{1}{4}-epsilon}$ for 0 less than epsilon less than 1/4, and global ...

Abstract Electroanaesthesia using electric fish handling gloves induced rapid and reversible sedation of Atlantic mackerel (Scomber scombrus) during surgical tagging without observable adverse effects on behaviour or tag retention. In the laboratory, survival analyses revealed that longer handling times and smaller body sizes significantly reduced ...

ABSTRACT Flavobacterium psychrophilum, the etiological agent of Rainbow Trout Fry Syndrome (RTFS) and Bacterial Coldwater Disease (BCWD), causes varying degrees of disease and mortality in salmonid aquaculture worldwide. Because its treatment relies on the use of antimicrobials, alternative interventions are of environmental and economic interest.

Abstract Understanding patterns of habitat use across trophic levels and the physical drivers of multispecies aggregations is essential to inform ecosystem‐based management. To achieve this, we quantified the spatial distribution and co‐occurrence of hotspots (defined using the Getis‐Ord statistic) for euphausiids and nine of their commercially ...
