Assessment of dose due to exposure to indoor radon and thoron progeny [PDF]
The components of the effective dose through inhalation from radon and its progeny are important for human health since they contribute to more than 50% of the total radiation dose from natural sources.

ABSTRACT This study explores the experiences of international students in the United States who come from countries that have been, or are being, affected by catastrophic events. The aim of the study is to understand the challenges such students face and to formulate supportive strategies that address these challenges.

Top‐Down Versus Bottom‐Up Atmospheric Emission Estimates From Oil and Natural Gas Operations
Abstract This study reviews results from literature to investigate top‐down versus bottom‐up emission estimates from oil and natural gas (O&NG) operations. Ten years ago, a landmark study by Brandt et al. (2014, https://doi.org/10.1126/science.1247045) found generally higher top‐down emissions determinations than industry estimates.

Abstract Coccolithophores are a group of marine phytoplankton precipitating about 50% of total calcite carbonate in the surface ocean. During the Pleistocene, coccolithophores experienced several periodic high‐abundance and dominance intervals (acmes) that significantly altered the ocean carbon cycle by increasing the production of carbonate in the ...

Measurement of radon and thoron concentrations of soil- gas in Al-Kufa city using RAD-7 detector
This work represents the set of measurements of radon and thoron concentrations levels of soil-gas in Al-Kufa city in Iraq using electric Radon meter (RAD-7). Radon and thoron concentration were measured in soil-gas in 20 location for three depth of (50,

Abstract The nature and cause(s) of the Mid‐Pleistocene Transition (MPT) remain enigmatic. Notably, the role of tropical Pacific oceanographic changes during the late MPT (∼0.9–0.6 Ma) remains understudied. Here, we generated ∼1.4‐Myr‐long Mg/Ca and δ18O records for the planktonic foraminifer Trilobatus sacculifer from IODP Site U1490 to reconstruct ...

Abstract Shifts in the phytoplankton assemblage induced by environmental changes have significant implications for carbon cycling and marine food webs, but remain poorly constrained across spatiotemporal scales. Here, we investigate the effects of rising sea surface temperatures and increased stratification on the phytoplankton composition and size in ...
