Affect has been shown to influence respiration in people. This paper takes this insight and proposes a real-time model to express affect through respiration in virtual humans. Fourteen affective states are explored: excitement, relaxation, focus, pain, relief, boredom, anger, fear, panic, disgust, surprise, startle, sadness, and joy. Specific respiratory patterns are described from the literatu...
This research aims to improve the correspondence between music and dance, and explores the use of human respiration pattern for musical applications with focus on the motional aspect of breathing. While respiration is frequently considered as an indicator of the metabolic state of human body that contains meaningful information for medicine or psychology, motional aspect of respiration has been...
The effect of climate change on peatlands is great importance due to their large carbon stocks. In this study, we examined microbial biomass and temperature O2 availability soil respiration surface subsurface Sphagnum peat. interactive biotic abiotic factors significantly affects respiration. Increasing enhanced the respiratory activity thus respiration, while there a threshold. more decomposed...
BACKGROUND AND AIMS Respiration is an important component of plant carbon balance, but it remains uncertain how respiration will respond to increases in atmospheric carbon dioxide concentration, and there are few measurements of respiration for crop plants grown at elevated [CO(2)] under field conditions. The hypothesis that respiration of leaves of soybeans grown at elevated [CO(2)] is increas...
Acclimation to elevated atmospheric carbon dioxide concentration and temperature of respiration by the foliage in the crown of Scots pine (Pinus sylvestris) trees is measured and modelled. Starting in 1996, individual 20-year-old trees were enclosed in chambers and exposed to either normal ambient conditions (CON), elevated CO2 concentration (EC), elevated temperature (ET) or a combination of E...
Since both cyanide and azide have been shown to block the oxidation of cytochrome c by cytochrome oxidase (l), it has been generally accepted that the toxicity of these substances is due to this property. A considerable amount of evidence has accumulated, however, indicating that aside and cyanide do not inhibit respiration in a parallel manner under all conditions. Thus Stannard (2) was able t...
Microbial respiration depends on microclimatic variables and carbon (C) substrate availability, all of which are altered when ecosystems experience major disturbance. Widespread tree mortality, currently affecting piñon–juniper ecosystems in southwestern North America, may affect C substrate availability in several ways, for example, via litterfall pulses and loss of root exudation. To determin...
Abstract: The new neonatal ventilation methods have been developed along with utilization of new technological tools.This device is synchronized with the patient’s respiratory efforts. The ideal synchronized breath needs to be synchronous with initiation, size, and termination of the breath without delay in detecting of initial resiratory effort by device .The synchrony of respiration contribut...
A perfusive method combined with an open-system carbon dioxide measurement system was used to assess rhizosphere respiration of Acer saccharum Marsh. (sugar maple) and Betula alleghaniensis Britton (yellow birch) seedlings grown in 8-l pots filled with coarse sand. We compared in vivo and in situ rhizosphere respiration between species, among light regimes (40, 17 and 6% of full daylight) and a...
A new approach to the problem of modelling and predicting respiration motion has been implemented. This is a dual-component model, which describes the respiration motion as a non-periodic time series superimposed onto a periodic waveform. A periodic autoregressive moving average algorithm has been used to define a mathematical model of the periodic and non-periodic components of the respiration...
