A rapidly incremented tethered-swimming maximal protocol for cardiorespiratory assessment of swimmers
(2020-01-01)
Incremental exercise testing is the standard means of assessing cardiorespiratory capacity of endurance athletes. While the maximal rate of oxygen consumption is typically used as the criterion measurement in this regard, ...
Daily activities are sufficient to induce dynamic pulmonary hyperinflation and dyspnea in chronic obstructive pulmonary disease patients
(Faculdade de Medicina / USP, 2012-01-01)
OBJECTIVE: The aim of this study was to measure dynamic lung hyperinflation and its influence on dyspnea perception in moderate and severe chronic obstructive pulmonary disease patients after performing activities of daily ...
Energy Storage for Complementary Services in Grid-Tied PV Systems
(2021)
The continuous increase in penetration of renewable-based power plants together with the
intermittent and variable nature of those natural resources have made grid stability issues a major
concern, imposing limitations ...
Modelo de leilão multiperíodo para sistemas hidrotérmicos em mercados pool de energia do dia seguinte
(Universidade Estadual Paulista (Unesp), 2016-06-10)
Neste trabalho propõe-se um modelo de leilão multiperíodo para um mercado pool do dia seguinte de sistemas hidrotérmicos, que leve em consideração as restrições intertemporais do sistema termelétrico (e.g. potência máxima ...
Barremian bivalves from the Huitrín formation, west-central Argentina: Taxonomy and paleoecology of a restricted marine association
(Paleontological Society, 2011-07)
The Cretaceous Huitrín Formation in west-central Argentina records the final connection of the Neuquén Basin to the Pacific Ocean. This formation is comprised of a variety of continental to marginal-marine sediments ...
Coupling of Acetaldehyde to Crotonaldehyde on CeO 2-x (111): Bifunctional Mechanism and Role of Oxygen Vacancies
(American Chemical Society, 2019-04)
Selective C-C coupling of oxygenates is pertinent to the manufacture of fuel and chemical products from biomass and from derivatives of C 1 compounds (i.e., oxygenates produced from methane and CO 2 ). Here we report a ...
A new solution to mitigate hydropeaking? Batteries versus re-regulation reservoirs
(Elsevier, 2019)
Hydropower plants frequently operate at high output during peak hours and at low output (or even shutoff) during off-peak hours. This scheme, called "hydropeaking", is harmful to downstream ecosystems. Operational constraints ...
Universality beyond power laws and the average avalanche shape
(Springer Nature, 2011-01-23)
The study of critical phenomena and universal power laws has been one of the central advances in statistical mechanics during the second half of the past century, explaining traditional thermodynamic critical points1, ...
