Reflections in a cracked mirror [PDF]

open access: yesBritish Journal of General Practice, 2009
How I hate the modern obsession with reflection. After every talk and lecture, at almost every trainers and appraisers meeting for the last few years and in everything associated with the medical learning industry, I am encouraged to reflect. To reflect on what I have learned and to shine that secondhand light on how my new knowledge will change the ...

Development of Plant-Mix-Type Modified Mixture with Excellent Flexibility and Stress Relaxation Properties for Ensuring High Resistance to Cracking

open access: yesEngineering Proceedings, 2023
Over the past few years, in order to extend the service life of pavements, the authors developed a special asphalt mixture that adequately prevents the ingress of water from the foundation layer of the asphalt into the top layers.

Metal Oxide/Nitrogen-Doped Carbon Nanosheet Heteronanostructures as Highly Efficient Electromagnetic Wave Absorbing Materials

open access: yesMolecules, 2021
In this paper, we will discuss the excellent broadband microwave absorption behaviors of Cu/CuO/carbon nanosheet composites: traces of copper and oxide embedded in a carbon nano-sheet not only cut down the high permittivity of adsorbs but also induce ...

Non-contact ultrasonic detection of angled surface defects [PDF]

open access: yes, 2011
Non-destructive testing is an important technique, and improvements are constantly needed. Surface defects in metals are not necessarily confined to orientations normal to the sample surface; however, much of the previous work investigating the ...

Influence of geosynthetic-interlayers on the performance of asphalt overlays on pre-cracked pavements [PDF]

open access: yes, 2017
The functions of geosynthetic-interlayers in retarding reflection cracking and improving fatigue performance of hot mix asphalt (HMA) overlays in flexible pavements are evaluated in this study. The delamination or debonding mechanisms of the overlays are

Practical Approaches for Acoustic Emission Attenuation Modelling to Enable the Process Monitoring of CFRP Machining

open access: yesJournal of Manufacturing and Materials Processing, 2022
Acoustic emission-based monitoring of the milling process holds the potential to detect undesired damages of fibre-reinforced plastic workpieces, such as delamination or matrix cracking. In addition, abrasive tool wear, tool breakage, or coating failures

Using small-angle X-ray scattering to investigate the compaction behaviour of a granulated clay [PDF]

open access: yes, 2015
The compaction behaviour of a commercial granulated clay (magnesium aluminium smectite, gMgSm) was investigated using macroscopic pressure-density measurements, X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray microtomography (XμT) and ...

The Reflective Cracking in Flexible Pavements [PDF]

open access: yesRomanian Journal of Transport Infrastructure, 2013
Abstract Reflective cracking is a major concern for engineers facing the problem of road maintenance and rehabilitation. The problem appears due to the presence of cracks in the old pavement layers that propagate into the pavement overlay layer when traffic load passes over the cracks and due to the temperature variation.
