Kinetics of the Dissolution Reaction of the UO Powder in Nitric Acid after Oxidation Volatilization at 850 °C.

Due to a series of factors such as variations in powder preparation methods, the kinetic parameter data for its dissolution in nitric acid solution exhibit dispersion. This study investigates the UO powder which underwent oxidation and volatilization at 850 °C. The particle size of the UO powder prior to dissolution was measured, and the surface area during dissolution was calculated under certain assumptions.

Experimental study on laser cutting process of simulated fast Reactor fuel rods.

The cladding of fast reactor fuel rods, made of stainless steel, presents significant challenges in cutting due to its ductility, which leads to increased tool wear and poor cut quality with traditional mechanical methods. Laser cutting has emerged as a superior alternative, offering non-contact precision, high efficiency, and suitability for radioactive environments. This study systematically investigates the effects of laser cutting parameters-cutting speed, focal position, power, and gas pressure-on the cutting quality of simulated fast reactor fuel rods.

Consequently, researchers worldwide are focusing on radiation-resistant fiber optic technology.

A potential virulence factor: Brucella flagellin FliK does not affect the main biological properties but inhibits the inflammatory response in RAW264.7 cells.

The bacterial flagellum is an elongated filament that protrudes from the cell and is responsible for bacterial motility. It can also be a pathogen-associated molecular pattern (PAMP) that regulates the host immune response and is involved in bacterial pathogenicity. In contrast to motile bacteria, the Brucella flagellum does not serve a motile purpose.

Methods: We randomly allocated 19,373 participants into 1 of the 3 screening arms in a 1:2:2 ratio: (1) one-time colonoscopy (n = 3883); (2) annual fecal immunochemical test (FIT) (n = 7793); (3) annual risk-adapted screening (n = 7697), in which, based on the risk-stratification score, high-risk participants were referred for colonoscopy and low-risk ones were referred for FIT. Three consecutive screening rounds were conducted for both the FIT and the risk-adapted screening arms.

Porous Copper-Loaded Zeolites for High-Efficiency Capture of Iodine from Spent Fuel Reprocessing Off-Gas.

Capturing volatile radionuclide iodine produced in the nuclear industry is a crucial environmental issue. In previous studies, the principal efficient adsorbent for iodine capture was silver-containing zeolite. As silver-containing zeolites are expensive, alternate copper-loaded porous zeolites, including CuCl loaded NaY reduced by H (denoted as HCuY) and CO (denoted as COCuY), were studied for iodine adsorption at moderate temperatures.

Methods: We analyzed the cross-sectional data from 40-80 years Chinese at a high risk of CRC from the Lanxi Pre-colorectal Cancer Cohort (LP3C) baseline survey, which was conducted between March 2018 and December 2019.

A Omp16 Conditional Deletion Strain Is Attenuated in BALB/c Mice.

spp. are facultative intracellular pathogens that invade, survive and proliferate in numerous phagocytic and non-phagocytic cell types, thereby leading to human and animal brucellosis. Outer membrane proteins (Omps) are major immunogenic and protective antigens that are implicated in virulence.

An ArsR Transcriptional Regulator Facilitates sp. Survival via Regulating Self and Outer Membrane Protein.

The arsenic acid-resistant (ArsR) family transcriptional regulators are widely distributed in microorganisms, including in the facultative intracellular pathogen spp. ArsR proteins are implicated in numerous biological processes. However, the specific roles of ArsR family members in remain obscure.

RNA-Seq Analysis Reveals the Role of Omp16 in -Infected RAW264.7 Cells.

Brucellosis is an endemic zoonotic infectious disease in the majority of developing countries, which causes huge economic losses. As immunogenic and protective antigens at the surface of spp., outer membrane proteins (Omps) are particularly attractive for developing vaccine and could have more relevant role in host-pathogen interactions.

Drinking tea before menopause is associated with higher bone mineral density in postmenopausal women.

Background: Though tea drinking years and menopause stages have been indicated to be related with bone mineral density (BMD), most human studies have not considered the impact of tea drinking beginning time. Whether drinking tea before or after menopause plays a role in BMD is still unclear. This study aims to analyze whether drinking tea before or after menopause influences BMD in Chinese postmenopausal women.

A double-edged sword: the association of daytime napping duration and metabolism related diseases in a Chinese population.
