Nondestructive examination of recovery stage during annealing of a cold-rolled low-carbon steel using eddy current testing technique [PDF]

, 2017
The recovery process in steel is usually investigated by conventional destructive tests that are expensive, time-consuming and also cumbersome. In this study, an alternative non-destructive test technique (based on eddy current testing) is used to ...

Non-destructive Test Methods for Corrosion Detection in Reinforced Concrete Structures

Nordic Concrete Research, 2020
Several inspection methods can be used to assess the corrosion state of steel reinforcement in concrete. Especially for periodical field surveys and monitoring, non-destructive testing (NDT) methods are to be preferred as they do not cause any or very ...

Sensing of the acoustic signal by waveguides

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008
The work is focused on the possibilities of accoustic emission (AE) signal sensing from surfaces inaccessible for commonly used sensors. The aim of the work is to verify the possibility of assembly of several measuring devices for maximalization of the ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Assessment of compressive strength of historic mixed masonry

Journal of Civil Engineering and Management, 2016
The majority of load-bearing masonry structures of historic buildings are built of mixed or stone masonry composed of regular or irregular (so-called quarry) masonry units – bricks, sedimentary and metamorphic rock – pos­sessing often very different ...

Prediction of ‘Nules Clementine’ mandarin susceptibility to rind breakdown disorder using Vis/NIR spectroscopy [PDF]

, 2012
The use of diffuse reflectance visible and near infrared (Vis/NIR) spectroscopy was explored as a non-destructive technique to predict ‘Nules Clementine’ mandarin fruit susceptibility to rind breakdown (RBD) disorder by detecting rind physico-chemical ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
