Pulmonary hematological parameters, energetic flight demands and their correlation with oxygen diffusion capacity in the lungs
(2007)
Hematological parameters of birds and mammals seem to respond to environmental requirements, such as hypoxia at high altitude and the energetic demands of locomotion and flight. In this work we hypothesize that lung capillary ...
Ischemic changes in exercise ECG in a hypertensive subject acutely exposed to high altitude Possible role of a high-altitude induced imbalance in myocardial oxygen supply-demand
(Elsevier, 2014)
In the 1930–1940s Levy and coworkers administered low oxygen tension (thus simulating exposure to an altitude of about 5000 m) while monitoring ECG, in order to demonstrate coronary inadequacy resulting from imbalance ...
Tidally driven sulfidic conditions in Peruvian mangrove sediments
(Springer, 2018)
The seasonal influence of tidal regimes on sulfidic conditions was studied in intertidal environments from a mangrove estuary in Northern Peru. Along two sampling stations, creek water and sediment cores were collected ...
Intraspecific variation of heat tolerance in a model ectotherm: The role of oxygen, cell size and body size
(2023)
Virtually all aspects of the biology of ectotherms are size-and temperature-dependent. Aerobic metabolism is often proposed to explain such relationships, with oxygen limitation setting limits to heat tolerance and ...
Phototrophic growth of Rubrivivax gelatinosus in poultry slaughterhouse wastewater
(Elsevier B.V., 2008-06-01)
Rubrivivax gelatinosus was grown in Pfennig's synthetic medium (PM) and in treated wastewater from poultry slaughterhouse (TW) to assess growth profiles for biomass production. Cultures inoculated at 1% (v/v) were grown ...
Application of microbial fuel cell technology for vinasse treatment and bioelectricity generation
(2019-01-15)
Objective: Our study evaluated the performance of different two-chambered microbial fuel cell (MFC) prototypes, operated with variable distance between electrodes and Nafion membrane and specific inoculum concentration, ...
Production and use of microbial biomass helping sustainability in tilapia production chain
(2019-09-01)
In this study, the cultivation of Rubrivivax gelatinosus in fish industry effluent was carried out to cause the depollution of the by-product and generate a protein–carotenoid-rich biomass suitable to be used in tilapia ...
Performance Evaluation of First-Order Hydraulic Models for COD Removal in Horizontal Subsurface-Flow Constructed Wetlands
(Asce-amer Soc Civil Engineers, 2017-10-01)
The aims of the present study are to verify the performance of four first-order hydraulic models and identify the model that best described the kinetics of the chemical oxygen demand (COD) removal in constructed wetlands. ...
