Behaviour influences thermoregulation of boreal moose during the warm season.

Management of large herbivores depends on providing habitats for forage supply and refuge from risks of temperature, predation and disease. Moose () accumulate body energy and nutrient stores during summer, while reducing the impact of warm temperatures through physiological and behavioural thermoregulation. Building on the animal indicator concept, we used rumen temperature sensors and GPS collars on captive moose ( = 6) kept in large natural enclosures to evaluate how behaviour and habitat selection influence the rate of change in rumen temperature during the growing season on the Kenai Peninsula, Alaska, USA.

Micellar Organocatalysis Using Smart Polymer Supports: Influence of Thermoresponsive Self-Assembly on Catalytic Activity.

Micellar catalysts with a switchable core are attractive materials in organic synthesis. However, little is known about the role of the shell forming block on the performance of the catalyst. Thermoresponsive block copolymers based on poly(-isopropylacrylamide--vinyl-4,4-dimethylazlactone) attached to different permanently hydrophilic blocks, namely poly(ethylene glycol), poly(,-dimethylacrylamide), and poly(2,3-dihydroxypropyl acrylate), were successfully synthesized via reversible addition/fragmentation chain transfer radical polymerization (RAFT).

Analysis of sequence-defined oligomers through Advanced Polymer Chromatography™ - mass spectrometry hyphenation.

In recent years, sequence-defined oligomers have attracted increasing interest in the polymer community and the number of new applications such as macromolecular data storage and encryption is increasing. However, techniques allowing sequence differentiation are still lacking. In this study, the focus is put towards a new strategy allowing structural distinction between sequence-defined oligomers with identical molecular weight and composition, but bearing different sequences.

End Group Stability of Atom Transfer Radical Polymerization (ATRP)-Synthesized Poly(-isopropylacrylamide): Perspectives for Diblock Copolymer Synthesis.

Studies on the end group stability of poly(-isopropylacrylamide) during the atom transfer radical polymerization (ATRP) process are presented. Polymerization of -isopropylacrylamide was conducted in different solvents using a copper(I) chloride/MeTren catalyst complex. The influence of the ATRP solvent as well as the polymer purification process on the end group stability was investigated.

Biomolecule Sensor Based on Azlactone-Modified Hydrogel Films.

A 3D hydrogel layer is probed by combining surface plasmon resonance with optical waveguide spectroscopy to detect biomolecules. A template terpolymer P(DMAAm-co-DMIAAm-co-VDMA) is synthesized via reversible addition-fragmentation chain-transfer polymerization. The terpolymer is then modified with an amino group bearing biotin to enable biomolecular recognition for streptavidin.
