Predicting Later-Life Outcomes of Early-Life Exposures [PDF]

open access: yesEnvironmental Health Perspectives, 2012
In utero exposure of the fetus to a stressor can lead to disease in later life. Epigenetic mechanisms are likely mediators of later-life expression of early-life events.We examined the current state of understanding of later-life diseases resulting from early-life exposures in order to identify in utero and postnatal indicators of later-life diseases ...

PREDICTION OF HONEY SHELF LIFE

open access: yesJournal of Food Quality, 2009
ABSTRACT Fourteen commercial honey samples of different botanical origin (acacia, chestnut, citrus, eucalyptus, multifloral) were stored for up to 18 months at room temperature. Both 5‐hydroxymethylfurfural (HMF) and diastase were evaluated and kinetics carried out.

Influence of axial load on internal pressure creep of Mod.9Cr-1Mo circumferential welded pipe

open access: yesNihon Kikai Gakkai ronbunshu, 2015
Mod.9Cr-1Mo steel(P91) is widely used for high temperature pipes in ultra-super-critical thermal power plants. However it was recently reported that the creep damage was detected at heat affected zone(HAZ) in welded joints of the pipes so-called the ...

Rethinking Life and Predicting Its Origin

open access: yesTheory in Biosciences, 2021
The definition, origin and recreation of life remain elusive. As others have suggested, only once we put life into reductionist physical terms will we be able to solve those questions. To that end, this work proposes the phenomenon of life to be the product of two dissipative mechanisms.

Remaining Useful Life Assessment of Slewing Bearing Based on Spatial-Temporal Sequence

open access: yesIEEE Access, 2020
Slewing bearing is one of key components in the large size machinery and its remaining useful life (RUL) prediction is required to schedule a future action to avoid catastrophic events, extend life cycles, etc.

Research on low cycle fatigue life prediction considering average strain

open access: yesMaterials Research Express, 2022
To address the difficult problems in the study of the effect of average strain on fatigue life under low-cycle fatigue loads, the effect of average strain on the low-cycle fatigue life of materials under different strain cycle ratios was discussed based ...

Thermal Fatigue Life Prediction of Thermal Barrier Coat on Nozzle Guide Vane via Master–Slave Model

open access: yesApplied Sciences, 2019
The aim of this paper was to develop a master−slave model with fluid-thermo-structure (FTS) interaction for the thermal fatigue life prediction of a thermal barrier coat (TBC) in a nozzle guide vane (NGV).

Degradation mechanism and life prediction of tailings and waste rock aggregate geopolymer concrete under freeze-thaw corrosion

open access: yesMaterials Research Express, 2022
To study the durability of tailings and waste rock aggregate geopolymer concrete (TWGPC), a large number of tailings and waste rock were used to replace natural sand and stone as aggregates, and a fly ash geopolymer was used to replace cement as ...
