The cracking appears to form a "slip band" effect, or standard solder fatigue cracking, as a result of the -40[degrees] to 125[degrees]C
thermal exposure. There was no evidence of cracking caused by processing defects.
Occurrence of reflections at nearly the same 2[theta] values, both prior to and after heat treatment suggests that the initial hexagonal crystal structure is left grossly unaffected by
thermal exposures. Despite the overall similarity, the patterns from the heat-treated samples manifest subtle differences.
Polymer free-radicals can be produced when energy is imparted to the molecule (for example, by ionizing radiation or elevated
thermal exposure) that results in the ejection of an electron.
Blood samples were collected via venipuncture from the jugular vein at 09:00 h and 15:00 h on d 7 from the start of the
thermal exposure, and the blood samples were collected into a non-anti-coagulant, a heparinized and an ethylenediaminetetraacetic acid (EDTA) coated vacutainers (BD, North Ryde, NSW, Australia).
Besides, concrete has low thermal conductivity and subsequently acts as insulation for the reinforcement, preserving the temperatures at the rebar level within a low range and thus allowing for an adequate strength during the
thermal exposure (Blontrock et al.
Perceived thermal discomfort can occur with or without changes to body core temperature and is a function of several factors including skin temperature, sweating rate/condition, psychological state, prior
thermal exposure, and individual expectation of the thermal conditions to be encountered.
26 min of
thermal exposure confirm this assumption.
The temperature cracks were traced on the specimens with a marker pen after
thermal exposure. During the load holding, the opening and spacing of stressed cracks were likewise traced.
The company is focused on developing a medical device platform to help patients living with hypertension symptoms through renal sympathetic denervation by delivering controlled microwave energy at the location of the sympathetic nerves while minimising
thermal exposure to non-targeted areas.
Knowledge of the daily patterns of
thermal exposure and the UVB zone of reptiles including the Texas horned lizard provides useful information for captive maintenance programs for conservation, education, and research.
Design of a concrete mixture with resistance to
thermal exposure for a certain period of time has been already classified among the passive fire protection methods.
