Oxygen uptake kinetics and time to exhaustion in cycling and running: A comparison between trained and untrained subjects
(2003-12-01)
The objective of the present study was to compare pulmonary gas exchange kinetics (VO 2 kinetics) and time to exhaustion (Tlim) between trained and untrained individuals during severe exercise performed on a cycle ergometer ...
Methane and carbon dioxide seasonal cycles at urban Brazilian inland sites
(Kluwer Academic Publ, 2004-02-01)
Methane and carbon dioxide seasonal cycles during years 1998 and 1999 at two Brazilian urban and inland sites are presented. The mixing ratio averages over the studied period of time were 1.80 ppm CH4 and 384.7 ppm CO2. A ...

Circadian entrainment to light-dark cycles involves extracellular nitric oxide communication within the suprachiasmatic nuclei
(Wiley Blackwell Publishing, Inc, 2010-03)
The ability to synchronize to light-dark (LD) cycles is an essential property of the circadian clock, located in mammals within the hypothalamic suprachiasmatic nuclei (SCN). Single light pulses activate nitric oxide (NO) ...

Variations of carbon monoxide concentrations in the Megacity of São Paulo from 2000 to 2015 in different time Scales
(2017-04-28)
Air pollution is an important public health issue. High levels of carbon monoxide in the atmosphere are hazardous to human health. Studies regarding the concentration of this and other gases in the atmosphere allow political ...
On the existence of stable population in life cycle models
(Elsevier Science Sa, 2016-01)
A common assumption adopted in life cycle general equilibrium models is that the population is stable at steady state, that is, its relative age distribution becomes constant overtime. An open question is whether the ...
