On the effects of temperature and pH on tropical and temperate holothurians

open access: yesConservation Physiology, 2021
 Ocean acidification and increased ocean heat content has direct and indirect effects on marine organisms such as holothurians (sea cucumbers) that are vulnerable to changes in pH and temperature. These environmental factors have the potential to influence organismal performance and fitness at different life stages.

Understanding the microstructural evolution and fretting wear behaviors of M50 bearing steel heat treated at different temperatures

open access: yesJournal of Materials Research and Technology, 2023
For M50 bearing steel, which is widely used in aerospace engine main bearings, fretting wear is an important but neglected category of wear failure during engine cold startup.

Temperature of a Temperate Glacier [PDF]

open access: yesJournal of Glaciology, 1972
AbstractThe closure of water-filled glacier bore holes is considered and it is concluded that freezing due to conduction to the surrounding ice is usually the dominant process. On this basis englacial temperatures are obtained from a bore hole near the equilibrium line of Blue Glacier, U.S.A., where the ice thickness is about 125 m.

Tempering Temperature Changes for Robust Development [PDF]

open access: yesCell, 2014
Developmental signaling pathways needed to evolve to be robust against environmental fluctuations. In this issue, Shimizu et al. reveal a complex system of interacting endocytic pathways that help to maintain consistent levels of Notch activity across a range of temperatures.

High-Temperature Tempered Martensite Embrittlement in Quenched-and-Tempered Offshore Steels [PDF]

open access: yesMetals, 2017
Embrittlement induced by high-temperature tempering was investigated in two quenched-and-tempered offshore steels. Electron backscattering diffraction and analysis of Kernel average misorientation were applied to study the coalescence of martensite; transmission Kikuchi diffraction coupled with compositional mapping was used to characterize the ...

Temperature Measurements in a Temperate Glacier [PDF]

open access: yesJournal of Glaciology, 1975
Temperatures have been measured at two sites in a temperate glacier (Blue Glacier, Washington, U.S.A.) to depths of 192 and 76 m. The accuracy, which varies between about 0.002 and 0.005 deg, is about an order of magnitude better than previously obtained.

Statistical Analysis and Fatigue Life Estimations for Quenched and Tempered Steel at Different Tempering Temperatures [PDF]

open access: yesMetals, 2017
In this paper, the statistical properties and fatigue life estimations of 0.44% carbon steel at different tempering temperatures are presented. The specimens were austenized at 900 °C for 10 min, quenched in water, tempered at different temperatures, and then machined to the design geometry and average surface roughness of Ra = 0.4 μm.
