High pressure limits of thermal rate constants of intramolecular hydrogen migrations, particularly 1,3 to 1,6 H-shift in propyl, butyl, pentyl and hexyl radicals, respectively, were calculated using the canonical variational transition state theory (CVT) with a multi-dimensional small-curvature tunneling (SCT) correction over the temperature range of 300-3000 K. The CCSD(T)/cc-pVDZ//BH&HLYP/cc-...

Whether glucose concentration increases during heat exposure because of reduced peripheral tissue uptake or enhanced appearance is currently unknown. This study aimed to report concentrations in both capillary and venous blood response a challenge passive heating (PH) assess whether affects healthy males. Twelve male participants completed two experimental sessions, where they were asked undert...

A geometrically constrained phosphine bearing a tridentate NNS pincer ligand is reported. The effect of the geometric constraint on electronic structure was probed by theoretical calculations and derivatization reactions. Reactions with N−H bonds result in formation cooperative addition products. thermochemistry these transformations strongly dependent substrate, ammonia activation being thermo...

This study investigated the effect of differing fluid volumes consumed during exercise, on cycle time-trial (TT) performance conducted under thermoneutral conditions (20 degrees C, 70% RH). Ten minutes after consuming a bolus of 6 ml x kg(-1) body mass (BM) of a 6.4% CHO solution and immediately following a warm-up, 8 male cyclists undertook a 1-h self-paced TT on 4 separate occasions. During a...
