Long‐term wheel‐running prevents reduction of grip strength in type 2 diabetic rats

open access: yesPhysiological Reports, 2021
Diabetic skeletal muscles show reduced contractile force and increased fatigability. Hands are a target for several diabetes‐induced complications. Therefore, reduced handgrip strength often occurs as a consequence of diabetes.

Long-Term Performance of High Strength Concrete [PDF]

open access: yesJournal of the Korea Concrete Institute, 2004
This paper describes an experimental investigation of how time-dependent deformations of high strength concretes are affected by maximum size of coarse aggregate, curing time, and relatively low sustained stress level. A set of high strength concrete mixes, mainly containing two different maximum sizes of coarse aggregate, have been used to investigate

An innovative micromechanics-based three-dimensional long-term strength criterion for fracture assessment of rock materials [PDF]

open access: yesFracture and Structural Integrity, 2018
Rocks may exhibit time-dependent behaviors. Long-term strength criterion significantly dominates creep failure of rocks. Rocks contain many microcracks, which lead to degrade of long-term strength.

Evaluating long-term strength of structures

open access: yesThermal Science, 2019
The issue of evaluating strength and service life is discussed as applied to structures, the exploitation properties of which are characterized by multi-parametric nonstationary thermal mechanical effects. The main requirements to mathematical models of the related processes are formulated.

Phase transformation and strength of hydrated circulating fluidised bed combustion ash sediment in an open environment over 15 years: implications for the long-term stability of ash waste plateaus [PDF]

open access: yesOil Shale
Low-temperature circulating fluidised bed combustion (CFBC) of oil shale results in Ca-rich ashes with low pozzolanic properties, raising concerns regarding the long-term stability of ash depositories.
