Estimation of radon and natural radioactive emissions from two of the most widely used construction materials in Egypt

open access: yesFrontiers in Built Environment, 2023
As the risk of lung cancer increases with increasing radon exposure, the preferred measure of this risk is the long-term average radon level. The assessment of the radiation risk in workplaces in Egypt is constrained by the lack of experimental data ...

Influences of intergrowth structure construction on the structural and electrical properties of the BBT-BiT ceramics

open access: yesFrontiers in Chemistry, 2022
Bismuth Layer Structured Ferroelectrics (BLSFs) have always been an important research direction of high Curie temperature piezoelectrical ceramics, and the construction of intergrowth structure has been considered as an effective method to improve the ...

To the Discussion of the Firing Method of Common Bolgar Ceramics in the Pre-Mongol and Early Golden Periods (on the Basis of Excavation CXCII at Bolgar Fortified Settlement)

open access: yesАрхеология евразийских степей, 2021
The firing method of common Bolgar ceramics remains an unsolved question. For a long time, the firing of common wheel pottery was only evaluated in subjective terms “bad” and “good”.

A recursive-faulting model of distributed damage in confined brittle materials [PDF]

open access: yes, 2006
We develop a model of distributed damage in brittle materials deforming in triaxial compression based on the explicit construction of special microstructures obtained by recursive faulting.

Octree-based production of near net shape components [PDF]

open access: yes, 2008
Near net shape (NNS) manufacturing refers to the production of products that require a finishing operation of some kind. NNS manufacturing is important because it enables a significant reduction in: machining work, raw material usage, production time ...

Further work at Kilise Tepe, 2007-11: refining the Bronze to Iron Age transition [PDF]

open access: yes, 2014
The excavations at Kilise Tepe in the 1990s inevitably left a range of research questions unanswered, and our second spell of work at the site from 2007 to 2011 sought to address some of these, relating to the later second and early first millennia. This
