Understanding and Helping International Students Cope When Catastrophes Strike in Their Home Countries: A Qualitative Study

The Journal of Humanistic Counseling, Volume 64, Issue S1, Page S117-S130, December 2025.
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

Earth's Future, Volume 13, Issue 11, November 2025.
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.

Shallower Living Depth Instead of Higher Seawater Alkalinity Enhanced Calcification in Bloom‐Forming Coccolithophores During Their Pleistocene Acme Event

AGU Advances, Volume 6, Issue 5, October 2025.
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 ...

Gradual Warming of Western Pacific Warm Pool Due To Weakening of Indonesian Throughflow During the Late Mid‐Pleistocene Transition

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
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 ...

Integrating Radon/Thoron and Gamma Radiation Exposure for a Realistic Estimation of Dose Arising from Building Materials

Applied Sciences
Long-term exposure to radon, thoron, and gamma radiation from building materials poses a significant health risk to occupants. Current methods for estimating radiation doses often fail to consider the combined impact of these sources.

Exhalation Rate Study of Thoron in Some Building Materials of the Iberian Peninsula

Proceedings, 2018
Thoron isotope has been growing in importance in the last years because, despite of its short half-life, can also contribute in the development of lung cancer.

Assessment of dose due to exposure to indoor radon and thoron progeny [PDF]

Nuclear Technology and Radiation Protection, 2010
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.

Contrasting Trends in Phytoplankton Diversity, Size Structure, and Carbon Burial Efficiency in the Mediterranean Sea Under Shifting Environmental Conditions

Journal of Geophysical Research: Oceans, Volume 130, Issue 8, August 2025.
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 ...

A Comparison of New and Established Foraminiferal Dissolution Proxies in Tropical Indian Ocean Deep‐Sea Sediments

Paleoceanography and Paleoclimatology, Volume 40, Issue 6, June 2025.
Abstract Assessing the preservation state of calcium carbonate microfossils preserved in deep‐sea sediments allows us to understand the impact of ocean chemistry on deep‐sea carbonate distribution and provides key information on potential biases affecting microfossil‐based proxies applied in the geological past.
