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 ...
Thermal degradation of geomembranes after exposure to heat
(Millpress Science Publishers, 2006-01-01)
HDPE and PVC geomembranes are sensitive to changes in their properties when in contact with high temperatures. The effects of hot temperature on polymeric geomembranes are assessed by the ASTM D794 and ASTM D5721.This paper ...

Beyond a single temperature threshold: applying a cumulative thermal stress framework to plant heat tolerance
(2023)
Most plant thermal tolerance studies focus on single critical thresholds, which are arbitrary and phenomenological, limiting the generality of findings across studies. In animals and microbes, thermal tolerance landscapes ...
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 ...
