Assessment of fluidized bed gasification of grapefruit solid waste
(2021-09-01)
This work assesses the effects of various process temperatures (700, 750, and 800 °C) and equivalence ratio (0.25; 0.30 and 0.35) on gasification of grapefruit (Citrus x paradisi) solid waste (GSW) in a fluidized bed ...
Global versus local - Mach's principle versus the equivalence principle
(2016-10-01)
The equivalence principle is the conceptual basis for general relativity. In contrast, Mach's principle, although said to have been influential on Einstein in his formulation of general relativity, has not been shown to ...
Unexpected East-West effect in mesopause region SABER temperatures over El Leoncito
(Elsevier, 2017-05)
We find that mesopause region temperatures determined by the SABER instrument on the TIMED satellite during nocturnal overpasses at El Leoncito (31.8°S, 69.3°W) are several kelvins higher when SABER observes from the East ...
Calculation of the external surface temperature of a multi-layer wall considering solar radiation effects
(Elsevier Science Sa, 2018-09)
Infrared thermography has become a valuable tool for providing reliable information on the constructive components of the envelope of existing buildings and for checking if the thermal behaviour of a construction is ...
Effects of temperature and meal size on the postprandial metabolic response of Leptodactylus latrans (Anura, Leptodactylidae)
(Wiley-Blackwell, 2019-10-15)
The postprandial increment of metabolism, often referred to as specific dynamic action (SDA), encompasses the summed costs of meal ingestion, digestion, absorption, and assimilation. Different SDA parameters, such as its ...
Long-term behaviour model of skid resistance for asphalt roadway surfaces
(CANADIAN SCIENCE PUBLISHING, 2010)
Skid resistance (SR) is relevant to road safety. Several researchers have showed that SR diminishes its value over time depending on the traffic-aggregated interactions, and the presence of heavy vehicles in the traffic ...
Temperature and grain size effects on the behavior of CuAlBe SMA wires under cyclic loading
(ELSEVIER, 2008-11-25)
This study evaluates the properties of a superelastic CuAlBe shape memory alloy under cyclic loading to assess its potential for applications in seismic resistant design. Wires phi = 0.5 mm, previously heated during different ...
