Radiative association of P and Cl atoms
(Springer, 2020-05-30)
Thermal rate constants for the formation of PCl radical via radiative association have been estimated from potential energy curves and dipole moments calculated by accurate ab initio methods. The formation of PCl through ...
Rate constants of quenching of the fluorescence of pterins by the iodide anion in aqueous solution
(Elsevier Science, 2012-07)
The fluorescence of various pterins (6-methylpterin, 6-hydroxymethylpterin, 6-formylpterin, and 6-carboxypterin) was quenched using iodide in neutral, aerated neutral phosphate buffer. Stern-Volmer plots and the fluorescence ...
Batch distillation: Better at constant or variable reflux?
(ELSEVIER SCIENCE SA, 2010)
Due to its outstanding flexibility, batch distillation is still widely used in many separation processes. In the present work, a comparison between constant and variable reflux operations is studied. Firstly, a mathematical ...
On the use of 9,10-dimethylanthracene as chemical rate constant actinometer in singlet molecular oxygen reactions
(SOCIEDAD CHILENA DE QUIMICA, 2000-12)
Time resolved near IR luminescence detection of singlet oxygen, O-2((1)Delta (g)), and steady-state photolysis experiments were performed to study in detail limitations and approaches involved when 9,10-dimethylanthracene ...
Clinical applicability of detomidine and methadone constant rate infusions for surgery in standing horses
(2019-05-01)
Objective: To determine the required rate of a detomidine infusion (loading dose 5 μg kg −1 ; initial rate 12.5 μg kg −1 hour −1 ) added to a constant infusion of methadone (0.2 mg kg −1 ; 0.05 mg kg −1 hour −1 ) for ...
Influence of exercise mode and maximal lactate-steady-state concentration on the validity of OBLA to predict maximal lactate-steady-state in active individuals
(Sports Medicine Australia, 2008-06-01)
The aim of this study was to analyze the effects of exercise mode on the validity of onset of blood lactate accumulation (OBLA-3.5-mM fixed blood lactate concentration) to predict the work-rate at maximal lactate steady ...
Formation of PS through radiative association
(Springer, 2020-02-01)
Quantum chemical calculations within the multireference configuration interaction with single and double excitation level of theory are presented and used to obtain the rate coefficient for the radiative association of ...
Thermal regime effects on the resting metabolic rate of rattlesnakes depend on temperature range
(Elsevier B.V., 2019-07-01)
While ectothermic organisms often experience considerable circadian variation in body temperature under natural conditions, the study of the effects of temperature on metabolic rates are traditionally based on subjecting ...
