Artificial Neural Network Optimization to Estimate Radon in Soil

Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 18, Issue 5, October 2025.
ABSTRACT Modeling and estimating radon concentration are of crucial interest to support health protection campaigns. In the literature, many studies concentrated on indoor radon, while few of them investigated the outdoor radon spatial distribution and the factors that influence its formation.

Subtle relict channels associated with large dolines in an area formerly beneath the Laurentide Ice Sheet, northern Ohio, USA

Boreas, Volume 54, Issue 4, Page 567-589, October 2025.
Low‐relief dry channels appear out of place across a glaciated karst landscape in northern Ohio. Channels are only a few metres deep cut into limestone and draped with a veneer of till. Several hypotheses are proposed for explaining the channels. Low‐relief dry channels are observed across the Bellevue‐Castalia Karst Plain of north‐central Ohio, USA ...

Morphometric analyses of dolines — the problem of delineation and calculation of basic parameters

Acta Carsologica, 2018
So far reported unstable correlations between environmental settings and doline geometry require a revision of doline delineating methods and morphometric analyses that follows from such input data.

Temporal and Ontogenetic Changes in Feeding Ecology of a Characid From Karst Dolines of the Neotropics

Ecology of Freshwater Fish, Volume 34, Issue 4, October 2025.
ABSTRACT Environmental and biological factors strongly shape fish diets, yet little is known about such influences in flooded Karst Dolines of the Neotropical region. This study examined the diet of Deuterodon luetkenii and assessed its temporal and ontogenetic variation in Lagoa Misteriosa, a karstic lagoon. Fish were sampled bimonthly over 1 year and

Identification, density and physio-graphic characteristics of Dolans in different altitude classes (Zagros karst areas) [PDF]

نشریه جغرافیا و برنامه‌ریزی
Doline is one of the most characteristic and basic surface and morphological forms of karst, as a result of the chemical effect of water on limestone that occurs in different shapes and sizes. Dolines differ in morphological characteristics.

Fusion of Remote Sensing and Applied Geophysics for Sinkholes Identification in Tabular Middle Atlas of Morocco (the Causse of El Hajeb): Impact on the Protection of Water Resource

Resources, 2020
The Causse of El Hajeb belongs to the Tabular Middle Atlas (TMA), in which thousands of karst landforms have been identified. Among them, collapse dolines and dissolution sinkholes have been highlighted as a source of environmental risks and geo-hazards.

Taking stock after 6 years—The first results of an ongoing project to establish new populations of a regionally endangered grasshopper Számvetés az első hat év után—egy regionálisan veszélyeztetett sáskafaj új populációinak létrehozását célzó projekt első eredményei

Insect Conservation and Diversity, Volume 18, Issue 5, Page 834-841, September 2025.
A conservation programme started in 2018 to establish new populations of the regionally endangered large banded grasshopper (Arcyptera fusca) in two mountain ranges in Hungary, Central Europe. Between 2018 and 2024, individuals were translocated to five mountain meadows from nearby populations by single or repeated translocations.

The Role of Snowmelt on the Recharge Dynamics of a Vadose Alpine Karst

Hydrological Processes, Volume 39, Issue 8, August 2025.
A unique combination of ERT and hydrological monitoring in a cave of an Alpine karst aquifer allows the investigation of various water infiltration processes. A three‐week observation of snowmelt in comparison to dry and wet summer conditions demonstrated that snowmelt leads to high water saturation in the bedrock due to diffuse enrichment, thus ...
