Gas exchange kinetics in elite runners.
… whether an established technique for measuring gas exchange kinetics could be applied as a test to differentiate between elite athletic groups. The subject groups selected for this study were 12 elite male sprinters (ST) and 12 elite male endurance runners (ET). A 300s pseudo random binary …

The economic challenge of leaf gas exchange
The exchange of water for carbon dioxide required for photosynthesis in the leaves of vascular plants couples the global terrestrial carbon and water cycles. It also acts as a selection pressure for the plant: on the one hand, gas exchange for photosynthesis is beneficial for survival and growth in …

Free-surface turbulence and air-water gas exchange
… the physical mechanisms of air-water gas transfer through direct measurements of turbulence at the air--water interface. To enable this study, a new approach to the particle image velocimetry (PIV) technique is developed in order to quantify free-surface flows. Two aspects of this work …

Gas exchange with a reflecting system for inhalational anaesthesia
… ACD is a modified heat- and moisture exchanger (HME) containing av bacterial and viral filter as well as a carbon filter. The ACD can be used during surgery for administering the inhalational agents isoflurane and sevoflurane as an alternative to low-flow anaesthesia systems. It can …

Computational models for respiratory gas exchange and their applications
… function of the lungs is the transport and exchange of oxygen and removal of carbon dioxide that is critical in supporting normal function of vital body organs. Various modelling studies have attempted to investigate and capture aspects of the gas exchange process and its regulation with …

GABA regulation of gas exchange in barley (Hordeum vulgare)
… guard cells are the primary gatekeepers for gas exchange between plants and the atmosphere, and therefore, modulate the rate of photosynthesis (i.e. plant energy production) and transpiration (i.e. plant water loss). It is well known that carbon gain and water loss through stomatal regulation …

Influence of tidal volume on pulmonary gas exchange during general anaesthesia
Background and objective: General anaesthesia impairs respiratory function. The present studies were performed to compare arterial concentration of sevoflurane, oxygen and carbon dioxide in normal and overweight patients ventilated with increased tidal volume (VT), or normal tidal volume with and …

White apple leafhopper affects apple fruit quality and leaf gas exchange
… Horticulture Research Farm were used to evaluate gas exchange characteristics of leaves injured by the white apple leafhopper (WALH). Two groups of leaves were used for gas exchange measurements. One group of 42 leaves had three leaves each with 0, 1, 2, 3, 5, 7, and 10 WALH per leaf on each of …

Development of a method for quantitative imaging of air-water gas exchange
… a new measurement method to investigate the exchange of a soluble alkaline gas (ammonia) from air to water was developed. Key feature of the method is that a linear relationship between the concentrations of the dissolved gas and the alkaline form of the indicator, that is selectively excited …

Translational Imaging of Pulmonary Gas-Exchange Using Hyperpolarized 129Xe Magnetic Resonance Imaging
… to probe the fundamental function of the lung - gas-exchange. </p><p>While a bulk of the inhaled HP <super>129</super>Xe stays in the alveolar spaces, its moderate solubility in the pulmonary tissues causes a small fraction of this xenon in the alveolar spaces to diffuse into the pulmonary …

Plant morphology and gas exchange in Hesperaloe: Influence on its adaptation for cultivation.
The working hypothesis for this dissertation was that the contrasting plant architecture, and the distinct native environments of Hesperaloe funifera and H. nocturna should be reflected in differences in their eco-physiological responses, and that these, in turn, would determine these species' …

Evaluation of clinical methods of pulmonary gas exchange assessment in the standing horse
… we developed clinical techniques to measure gas exchange efficiency in horses. These techniques were then used to evaluate horses with varying degrees of lower respiratory disease. Three groups of horses (Group 1: asymptomatic, n=6; Group 2: symptomatic only with rebreathing, n=11; Group 3: …
