Development of a micro heat exchanger made with ceramic multi-layers (LTCC) and its setup to gas flow measurements
A green ceramic tape micro heat exchanger was developed using LTCC technology. The device was designed by using a CAD software and 2D and 3D simulations using a CFD package (COMSOL Multiphysics) to evaluate the fluid ...
Effect of saline infusion for the maintenance of blood volume on pulmonary gas exchange during temporary abdominal aortic occlusion
(Associação Brasileira de Divulgação Científica, 2007-03-01)
We analyzed the effects of saline infusion for the maintenance of blood volume on pulmonary gas exchange in ischemia-reperfusion syndrome during temporary abdominal aortic occlusion in dogs. We studied 20 adult mongrel ...
Instantaneously measured traits may detect non-plastic ecophysiological performances in response to drought, explaining distributions of Styrax species in the Cerrado
We analyzed the differences between irrigated and non-irrigated plants of three congeneric Styrax species that present distinct distribution patterns in the physiognomies of the Cerrado vegetation in Brazil. Styrax ferrugineus ...
Leaf gas exchange and yield of three upland rice cultivars.
(Bragantia, Campinas, v. 74, n. 1, p. 1-8, jan./mar. 2015., 2015)
The Temperature and Humidity in a Low-Flow Anesthesia Workstation With and Without a Heat and Moisture Exchanger
(Lippincott Williams & Wilkins, 2011-09-01)
BACKGROUND: The Drager Primus anesthesia workstation has a built-in hotplate to heat the patient's exhaled gas. The fresh gas flow is mixed with the heated exhaled gas as they pass through the soda lime canister. A heat ...
Whole plant open chamber to measure gas exchange on herbaceous plants
(Instituto de Investigaciones Agropecuarias, 2016-03)
Much of our understanding about CO2 and H2O gas exchange in plants has been gained from studies at leaf level. Extrapolation of results to whole plant is difficult and not always accurate. In order to overcome this limitation, ...
Comparative gas exchange performance during the wet season of three Brazilian Styrax species under habitat conditions of cerrado vegetation types differing in soil water availability and crown density
(Elsevier Gmbh, Urban & Fischer Verlag, 2011-01-01)
We studied the influence of environmental conditions in different vegetation types of the Brazilian savanna (cerrado s.l.) on CO2 assimilation and water use efficiency of Styrax ferrugineus, S. camporum and S. pohlii, which ...
Assessing the role of vertical leaves within the photosynthetic function of Styrax camporum under drought conditions
Previous evidence has demonstrated that vertical leaves of Styrax camporum, a woody shrub from the Brazilian savanna, have a higher net photosynthetic rate (P (N)) compared with horizontal leaves, and that it is detected ...
