Survey of Radon and Thoron Levels in the Air of Urban and Rural Dwellings in Yazd Province: Perspective of Stone Type and Construction Materials

open access: yesIndoor Air, Volume 2025, Issue 1, 2025.
The present study was aimed at assessing the concentrations of Rn and Th gases in the indoor air of residential homes in urban and rural areas near the active faults in Yazd province. Sampling and measurements were performed for 6 months (autumn and winter) in 2024 using the RAD7 device.

Size normalizing planktonic Foraminifera abundance in the water column

open access: yesLimnology and Oceanography: Methods, Volume 22, Issue 10, Page 701-719, October 2024.
Abstract Planktonic Foraminifera have been collected from the water column with different plankton sampling devices equipped with nets of various mesh sizes, which impedes direct comparison of observed quantifications. Here, we use data on the community size structure of planktonic Foraminifera to assess the impact of mesh size on the measured ...

A New Method for the Detection of Siliceous Microfossils on Sediment Microscope Slides Using Convolutional Neural Networks

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 129, Issue 9, September 2024.
Abstract Diatom communities preserved in sediment samples are valuable indicators for understanding the past and present dynamics of phytoplankton communities, and their response to environmental changes. These studies are traditionally achieved by counting methods using optical microscopy, a time‐consuming process that requires taxonomic expertise ...

The global genetic diversity of planktonic foraminifera reveals the structure of cryptic speciation in plankton

open access: yesBiological Reviews, Volume 99, Issue 4, Page 1218-1241, August 2024.
ABSTRACT The nature and extent of diversity in the plankton has fascinated scientists for over a century. Initially, the discovery of many new species in the remarkably uniform and unstructured pelagic environment appeared to challenge the concept of ecological niches.

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

open access: yesApplied 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.

Pengukuran Konsentrasi Thoron (220 Rn) di Udara dalam Ruangan secara Kontinu Menggunakan Pylon Model WLx [PDF]

open access: yes, 2011
Konsentrasi thoron ( 220 Rn) pada lokasi tertentu lebih besar dari pada radon ( 222 Rn), namun keberadaannya selalu terabaikan. Hal ini disebabkan oleh kesulitan dalam kalibrasi dan diskriminasi antara radon dengan thoron.

A user‐friendly method to get automated pollen analysis from environmental samples

open access: yesNew Phytologist, Volume 243, Issue 2, Page 797-810, July 2024.
Summary Automated pollen analysis is not yet efficient on environmental samples containing many pollen taxa and debris, which are typical in most pollen‐based studies. Contrary to classification, detection remains overlooked although it is the first step from which errors can propagate.

Which Acceptable Agreements are Equilibria? [PDF]

open access: yes
I propose a normal form game of agreement formation in which each player's strategy is to say for each size of agreement whether it is acceptable or not. I propose a refinement, which guarantees that each one of these choices is self-enforcing.
