Effect of Pre-Stressing on the Acid-Stress Response in Bifidobacterium Revealed Using Proteomic and Physiological Approaches. [PDF]

open access: yesPLoS ONE, 2015
Weak acid resistance limits the application of Bifidobacteria as a probiotic in food. The acid tolerance response (ATR), caused by pre-stressing cells at a sublethal pH, could improve the acid resistance of Bifidobacteria to subsequent acid stress.

Influence of Pre-Stressing on Tieback Retaining Wall for Sandy Soils Excavations

open access: yesJournal of the Civil Engineering Forum, 2021
Pre-stressed ground anchor systems or tieback systems are commonly used at wide and irregular-shaped excavations, with the advantage of lower cost and ease of construction compared to the braced excavations, but they come with the drawback on permits for

Pre-Stress Losses in FRP Pre-Stressed Reinforced Concrete – Subject Overview

open access: yesArchives of Civil Engineering, 2018
AbstractFiber reinforced polymers (FRPs) due to their specific high-strength properties become more and more popular and replace traditional structural materials like conventional steel in prestressed concrete structures. FRP reinforced structures are relatively new when compared to structures prestressed with steel tendons.

Calibrating of a Simulation Model to Predict the Flexural Capacity of Pre-Stressed Concrete Beams

open access: yesApplied Sciences, 2023
Simulation models based on finite elements are currently indispensable tools for predicting the structural behavior of both reinforced and pre-stressed concrete elements. This work develops a simulation model of structural linear elements of pre-stressed
