Research on the method to measure the average radon exhalation rate of room inner surface

Nuclear Engineering and Technology
In high-rise buildings, radon from building materials is one of the main sources of indoor radon. People spend an average of 80 % of their time indoors every day.

Radon Gas Risk Indices in Water on Fractured Basement of Ayetoro Housing Scheme, Oyo [PDF]

Physics Access
Radon gas, a naturally occurring radioactive element, presents significant health risks, particularly in areas with fractured basement geology, where subsurface characteristics can elevate its concentration.

Incorporating an Elevated Perfusion Index in the Right Hand Enhanced Screening Sensitivity for Critical Aortic Arch Obstruction in Newborn Infants

Acta Paediatrica, Volume 114, Issue 7, Page 1570-1575, July 2025.
ABSTRACT Aim Newborn infants with critical aortic arch obstruction are often undiagnosed at discharge, despite screening. This study investigated if adding the perfusion index improved early detection. Methods We retrospectively studied 38 newborn infants with critical aortic arch obstruction, who were routinely screened in 2014–2019 by 13 Swedish ...

Radiocarbon analysis reveals decomposition of old soil organic carbon into dissolved inorganic carbon in a subtropical mangrove ecosystem

Limnology and Oceanography, Volume 70, Issue 6, Page 1740-1754, June 2025.
Abstract The outwelling of remineralized dissolved inorganic carbon (DIC) from the subsurface soil layer through tidal pumping has recently been noted for its importance in the blue carbon budget of mangroves. However, the age of soil organic carbon (SOC) that has been decomposed into DIC remains uncertain.

Assessment of radon exhalation rates in mineral rocks used in building decoration in Nigeria

Radiation Protection and Environment, 2021
The recent interest in the applications of mineral rocks for interior building decoration has been a major concern from the radiological perspective because the breaking down of rocks into various shapes and sizes releases radioactive gaseous element ...

A mangrove nitrous oxide sink attenuates methane climate impacts

Limnology and Oceanography Letters, Volume 10, Issue 3, Page 298-307, June 2025.
Abstract We resolve mangrove nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2) vertical exchange with the atmosphere and lateral exchange with the ocean. Our new observations in Brazil were combined with literature data to reassess the overall mangrove carbon sequestration potential.

High Methane Production and Emission From Tropical Seagrasses Through Methylotrophic Methanogenesis

Geophysical Research Letters, Volume 52, Issue 5, 16 March 2025.
Abstract Methane (CH4) is a potent greenhouse gas that reduces the carbon sequestration capacity of seagrass meadows. However, our understanding of CH4 production and emission from these important carbon sinks is limited. Here we conducted biogeochemical experiments to identify methylotrophic methanogenesis as the primary methanogenesis pathway in a ...

The yeast RAD7 and RAD16 genes are required for postincision events during nucleotide excision repair. In vitro and in vivo studies with rad7 and rad16 mutants and purification of a Rad7/Rad16-containing protein complex.

The Journal of biological chemistry, 1998
In eukaryotes, nucleotide excision repair (NER) is a complex reaction requiring multiple proteins. In the yeast Saccharomyces cerevisiae, two of these proteins, Rad7 and Rad16, are specifically involved in the removal of lesions from transcriptionally silent regions of the genome in vivo. Extracts prepared from rad7 or rad16 mutant cells are deficient,
