Obtaining the fatigue laws of bituminous mixtures from a strain sweep test: effect of temperature and aging [PDF]

open access: yes, 2017
Fatigue is associated with the deterioration caused by applying repeated loads, and is affected by temperature or aging. Generally, time sweep tests are used to simulate fatigue, in order to obtain the fatigue laws.

Calendar aging mechanism of NCM811/graphite-SiOx pouch cells at different temperatures

open access: yesCailiao gongcheng, 2023
Considering that a personal car spends about 95% of its life in parking mode, calendar aging can have a significant impact on battery life. High temperature storage is a common method for rapid evaluation of battery calendar life.

Environmental conditions during early life accelerate the rate of senescence in a short-lived passerine bird [PDF]

open access: yes, 2015
Environmental conditions experienced in early life may shape subsequent phenotypic traits including life history. We investigated how predation risk caused by domestic cats (Felis silvestris catus) and local breeding density affected patterns of ...
