Chemical Durability of Uranium Oxide Microspheres for Use as QC Materials for Nuclear Safeguards.

This study investigates the chemical durability of uranium oxide microparticles (UO and UO), as potential reference materials for nuclear safeguards. To optimize long-term preservation, the particles were exposed to three different storage media: dilute nitric acid (10 mol L HNO), deionized water, and ethanol. Dissolution rates in nitric acid (∼5 × 10 g.

Contamination of Bivalve , the Case of Radiocobalt in a Context of Environmental Release.

Since the end of nuclear weapon testing, anthropogenic metallic radionuclides have originated from nuclear accidents such as Chernobyl and Fukushima and controlled releases from the nuclear industry. Co is an activation product found in the effluents of nuclear power plants, mobile nuclear reactors, and fuel reprocessing facilities. In this paper, we are addressing the question of (radio)cobalt speciation upon bioaccumulation in the sentinel organism after contamination in a pseudo-natural system.

Chronic exertional compartment syndrome in the forearm: Ultrasound-guided surgical technique.

Introduction: Chronic exertional compartment syndrome of the forearm is most commonly associated with exercise. It presents as cramping after a few minutes of activity, requiring cessation of exercise. We describe an ultrasound-guided surgical technique for the treatment of forearm chronic exertional compartment syndrome.

Pathogenesis of prosthetic joint infections: bacterial adhesion and internalization in osteoblasts, synoviocytes and endothelial cells.

is frequently isolated during prosthetic joint infections (PJIs). Unlike , its internalization and persistence within cells are controversial. We aimed to determine whether internalization is involved in the pathophysiology of PJIs.

[Management of a fetus suspected of differences of sex development (DSD)].

The management of a fetus suspected of having a difference in genital sexual development (DSD) is a complex situation. In cases of complete discordance or an unusual appearance of the external genitalia (EG), management always begins with a diagnostic morphological ultrasound. This ultrasound aims to provide detailed imaging of the EG and internal genitalia (IG), focusing on identifying the presence of Müllerian derivatives and detecting any associated malformations.
