Measuring and modelling residual stresses in polymer-based dental composites

open access: yes, 2022
S.293-310The relevance of residual stresses for the marginal integrity of dental fillings is well known but the level of stress is not. An overview of the experimental and theoretical studies on residual stresses in dental composites is given and the ...

Getting stress out of stressed‐out stress granules [PDF]

open access: yesThe EMBO Journal, 2017
Amyotrophic lateral sclerosis (ALS) pathology is linked to the aberrant aggregation of specific proteins, including TDP‐43, FUS, and SOD1, but it is not clear why these aggregation events cause ALS. In this issue of The EMBO Journal , Mateju et al (2017) report a direct link between misfolded proteins accumulating in stress granules and the phase ...

An inverse method for evaluating weld residual stresses via fatigue crack growth test data [PDF]

open access: yes, 2010
This paper presents an inverse method for calculating the thermal residual stresses in welded specimens via measured fatigue crack growth rates. Firstly, fracture-mechanics superposition law has been used to extract the stress intensity factor due to ...

Parthenium hysterophorus’s Endophytes: The Second Layer of Defense against Biotic and Abiotic Stresses

open access: yesMicroorganisms, 2022
Parthenium hysterophorus L. is considered an obnoxious weed due to its rapid dispersal, fast multiplications, and agricultural and health hazards. In addition to its physio-molecular and phytotoxic allelochemical usage, this weed most probably uses ...
