Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Numerical Exploration of Thermal Shock Resistance in MgO–C Refractories

Advanced Engineering Materials, EarlyView.
A mesostructure‐resolved numerical framework is developed to evaluate the thermal shock resistance of MgO–C refractories. By modeling interface debonding under rapid temperature changes and introducing a modified thermal shock parameter that accounts for mesocracks, the study shows how graphite content and aggregate size influence thermal shock ...

The contribution of dermal exposure to the internal exposure of bisphenol A in man

Toxicology Letters, 2011
New findings on Bisphenol A (BPA) contents in thermal printing papers, and receipts, in g/kg concentrations and on its dermal uptake (up to 60%) prompted us to assess the risk arising from dermal exposure. Using physiologically based toxicokinetic modelling, we simulated concentrations in blood, in liver and kidney, the target organs exhibiting the ...

Fetal exposure to isotretinoin—An international problem

Reproductive Toxicology, 2008
Isotretinoin is a known teratogen. Pregnancy prevention programs aimed at minimizing isotretinoin exposure in pregnancy have been implemented in North America with limited success.To compare the management of fetal risk of isotretinoin in three countries, including information given to women, implementation of contraceptive methods, and pregnancy ...

The International Dimensions of Lead Exposure

International Journal of Occupational and Environmental Health, 1995
Lead poisoning is among the most prevalent and serious preventable diseases of occupational and environmental origin. Many sources contribute to human exposures, and the residues from past uses continue to present risks due to contamination of dusts, soils, and drinking water.

A Review of International Microwave Exposure Guides

American Industrial Hygiene Association Journal, 1970
The use of higher frequency microwave generating equipment has increased considerably since the development of radar and range-finder equipment in the early 1940's. Occupational exposure criteria were not officially proposed in the United States until 1958 when a maximum exposure of 10 milliwatts per square centimeter was established for United States ...

EXTERNAL AND INTERNAL EXPOSURE TO FUKUSHIMA RESIDENTS

Radiation Protection Dosimetry, 2016
The Great East Japan Earthquake of 11 March 2011, caused the Fukushima Daiichi Nuclear Power Plant Accident, which resulted in the release of a large amount of radioactive materials into the environment, and there is a serious concern about the radiation effects on the health of residents living in the affected areas. The evaluation of exposure dose is

The overview of internal exposure monitoring in Lithuania

Radiation Protection Dosimetry, 2007
This study deals with analysis of situation and results of internal exposure monitoring of radiation workers and population in Lithuania. Radiation workers are assessed for internal exposures by direct methods--whole body counting or organ counting by gamma spectrometry at the Radiation Protection Centre and Ignalina Nuclear Power Plant (INPP).
