The effects of slow rib raising on heart rate, blood pressure, respiration rate and pain pressure threshold
Mobilization techniques are commonly employed by manual therapists to treat spinal pain or spinal dysfunction. Many authors postulate different mechanisms by which mobilization techniques can produce positive outcomes involving the sympathetic nervous system, however supporting evidence remains …

Gypsy moth egg development: a model of phenological events
… and postdiapause. A technique of measuring respiration rates of individual eggs was developed and respiration rate was used as a physiological variable to distinguish the phases. The pattern of respiration rate provided strong evidence in support of three distinct developmental phases. …

Respiration during development and germination of muskmelon seeds (Cucumis melo L.)
Respiration rates of developing muskmelon (Cucumis melo L.) seeds were determined polarographically using a Clark-type O₂ electrode (Hansatech LD2). Seeds were obtained from fruits harvested 20, 30, 40, and 50 days after anthesis (DAA). Respiration (O₂ uptake) was measured for fresh intact seeds …

Physiological Sensor System for a wireless tactile display
… mobile user. Two physiological variables, heart rate and respiration rate, were selected for initial study, and technologies that could be used to measure these variables were evaluated. The PSS was required to be non-invasive, lightweight, and low-power. Initial studies indicated that heart rate …

THE RESPIRATORY RESPONSE OF TRPV1 KNOCKOUT MICE TO TRIGEMINAL IRRITANTS
… pattern which results in a decrease in respiration rate. This patterned respiration rate depression has been used as an indicator of sensory irritation, the “Alaire Test.” In the present study, an air dilution olfactometer was used to administer volatile compounds to unanesthetized mice …

Kinetics of Microbial Respiration
… thesis I develop a thermodynamically consistent rate law for microbial respiration. Previous approaches to predicting the rate of microbial respiration have relied on empirical relations, such as the Monod and dual-Monod equations, which do not consider how energy available in cell's environment …

Bioindicators of Reductive Dechlorination in a Dehalococcoides ethenogenes-Containing Mixed Culture: Transcriptional Trends With Respect to Substrate Type, Substrate Concentration, and Culture Operation
… were achieved and that increases in PCE loading rate led to corresponding increases in chloroethene respiration rate. Regulation of steady-state transcript levels of most bioindicators was sensitive to chloroethene respiration rate and/or concentration. Within a limited range of respiration rates …

The effect of rapid rib raising technique on heart rate, respiratory rate, pain pressure threshold and systolic and diastolic blood pressure in asymptomatic participants
… output included blood pressure, heart rate, respiratory rate and pain pressure threshold and were recorded at the end of each rest and intervention period. There was a significant increase in respiration rate after rapid articulation when compared to placebo and control groups. No other …

Possible mechanisms controlling the intracellular level of inorganic polyphosphate during synchronous growth of chlorella pyrenoidosa
The endogenous respiration rate and the intracellular ATP/ADP ratio were determined during synchronous growth of a high temperature strain of Chlorella pyrenoidosa in order to correlate their activities with a proposed mechanism for the control of intracellular levels of inorganic acid-insoluble …

Physiological And Psychological Responses To 911 Emergency Tapes
… mood state and arousal except in the instance of respiration rate and negative mood; those with higher scores on negative mood displayed higher levels of respiration. Personality factors and empathy were examined for their predictive value on level of arousal, and yielded insignificant results. …

Linking soil respiration to hydrologic conditions and climate change
Respiration of organic carbon in soils is one of the largest terrestrial sources of atmospheric CO2 and shifts in the rate of this flux poses one of the largest potential impacts on global warming. Previous studies have found that temperature and soil moisture contents exert first order controls on …

Respiration rates and Factors which Influence the levels of Carbohydrates and Lipids in Honey Bee Eggs (<I>Apis mellifera </I>Linnaeus)
Respiration rates and changes in the amount of nutrients in queen-laid and worker-laid eggs of the honey bee, <I>Apis mellifera</I> L., were determined for the 3 days of embryonic development. Respiration was quantified by measuring the amount of CO₂ produced during 13 hr of artificial incubation …

Derivation of the respiratory rate signal from a single lead ECG
It has been long established that respiration has an influence on heart rate, and this effect is called respiratory sinus arrhythmia. As a result, two inferences can be postulated: first respiration information can be derived from cardiac activity, and second this effect offers the potential of …

Gamma and X-ray Irradiation Improve Postharvest Shelf-Life in 'Bartlett' Pears
… temperature for four and two days, respectively. Respiration rate and ethylene production were measured during fruit ripening. Color, firmness, titratable acidity, soluble solids contents, and occurrence of superficial scald was measured at the climacteric peak. Ripening was accelerated in all …

A numerical study of convective heat transfer in stored respiring agricultural produce
… in which local temperature dependent respiration heat generation occurs. In the numerical investigations conducted, both adiabatic and isothermal boundary conditions are considered for the cooling and storage process. The influence of size, respiration rate and permeability on natural …

Evaluating Scenarios That Can Startle and Surprise Pilots
… failure), while startle is the associated exaggerated effect of an unexpected condition (e.g., thunder sound). Forty pilots were tested in a basic aviation training device configured to a Cessna 172 (single-engine) and a Baron 58 (multi-engine). Each pilot flew the single- and multiengine …

The Effect of Supplemental Grape Seed Extract on Pig Growth Performance and Body Composition During Heat Stress
… (12mg/kg body weight). Body temperature (TB), respiration rate (RR) and feed intake (FI) were measured daily. Body composition was measured by dual-energy X-ray absorptiometry (DXA). Respiration rate and TB increased in the HS control group compared to the TN control group (p<0.05), however GSE …

Using Silvopasture to Mitigate Heat Stress in Grazing Beef Cattle
… trial in East Texas. Data were collected on respiration rate, heart rate, heat stress scores, and behaviors including eating, ruminating, walking, and resting. Average respiration rates and behavior proportions did not differ significantly between treatments. Afternoon periods showed peak …

Characterization of chemical composition, milling properties and carbon dioxide diffusivity resulting from early harvest corn and corn stover
… corn in the diffusion cell. A source term (CO2 respiration rate) was introduced in the diffusion equation to account for the CO2 production by corn during the diffusion process. The corn respiration rate increased when temperature and corn moisture content increased. As respiration rate …
