Evaluation of mechanical and thermal properties after chemical degradation of PVC and HDPE geomembranes
(2013-06-10)
Chemical compatibility between geomembranes and site-specific waste liquids should be assessed since the waste liquids are highly complex mixtures. This paper presents some considerations about the chemical compatibility ...
BACKGROUND THERMAL CONTRIBUTIONS IN TESTING THE UNRUH EFFECT
(American Physical Soc, 1995-09-15)
We consider inertial and accelerated Unruh-DeWitt detectors moving in a background thermal bath and calculate their excitation rate. It is shown that for fast moving detectors such a thermal bath does not affect substantially ...
Effect of thermal cycling on microleakage between hard chairside relines and denture base acrylic resins
(Wiley-Blackwell, 2011-06-01)
Objectives:Microleakage is a pre-stage of debonding between hard chairside relines and denture base acrylic resins. Therefore, it is important to assess them with regard to the longevity of the relined denture. This study ...
Effective thermal conductivity of beans via a steady-state method
(Marcel Dekker Inc, 2004-03-01)
Steady-state concentric cylinder equipment was used to determine the effective thermal conductivity of beans (Phaseolus vulgaris). The measuring cell had no heated end guards and its length to diameter ratio was 10.5. Glass ...
Effect of storage in artificial saliva and thermal cycling on Knoop hardness of resin denture teeth
(2010-07-01)
Purpose: This study aimed to evaluate the effect of different storage periods in artificial saliva and thermal cycling on Knoop hardness of 8 commercial brands of resin denture teeth. Methods: Eigth different brands of ...
Evolutionary design of a satellite thermal control system: Real experiments for a CubeSat mission
(Pergamon-Elsevier Science Ltd., 2016)
This paper studies the use of artificial evolution to automate the design of a satellite passive thermal control system. This type of adaptation often requires the use of computer simulations to evaluate fitness of a large ...
Decay resistance of thermally-modified Eucalyptus grandis wood at 140 degrees C, 160 degrees C, 180 degrees C, 200 degrees C and 220 degrees C
(Elsevier B.V., 2010-12-01)
The objective of this study was to evaluate the effect of thermal treatment on the biological resistance of Eucalyptus grandis wood to the decay fungus Picnoporus sanguineus. Boards from 5 years and 11 months old E. grandis ...
PCM thermal insulation in buildings

Thermal behavior and kinetics assessment of ethanol/gasoline blends during combustion by thermogravimetric analysis
(2017-01-01)
The use of ethanol as a fuel or as an additive blended with gasoline is very important for most countries, which aim to reduce the heavy dependence on fossil fuels and mitigate greenhouse gases emission. An increased use ...
Heat pump for thermal power production in dairy farm
(2016-01-01)
Besides cold for milk cooling, dairy facilities need to produce hot water for cleaning of tools and equipment. Overall, ohmic heating has been used in dairy farms, increasing power consumption and manufacturing costs. ...
