The Zooplankton International Geospatial dataset: A global repository of spatiotemporal freshwater zooplankton community composition data from lakes and reservoirs to support ecological research

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Zooplankton transfer substantial energy in aquatic food webs and are used as indicators of environmental change. Syntheses of zooplankton community dynamics globally require datasets that span a wide range of environmental gradients; however, these datasets are limited due to methodological differences across programs, taxonomic ...

Porous and Permeable Crystalline Basement: Evidence for Large‐Scale Hydraulic Connectivity at Kivetty, Finland

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Porosity and permeability in crystalline shield basement are commonly assumed to be low, yet some fault zones sustain fluid circulation over kilometer scales. Here we quantify multiscale fault‐zone connectivity at Kivetty, central Finland, by integrating legacy deep‐borehole data, including packer tests, downhole logs, and a long‐term multi ...

Relationship of Physical Properties of Limestone and Marblewith Rock Strength Under Specific Geological Conditions from Khyber Region Hunza

open access: yesInternational Journal of Economic and Environment Geology, 2020
The uniaxial compressive strength (UCS) is one of the input parameters mostly used in surface and underground designs. A literature review revealed that most of the empirical equations between UCS and Schmidt hammer rebound ...

Caribbean Historical Geographies and British Geography

open access: yesArea, Volume 58, Issue 3, September 2026.
ABSTRACT This paper draws from discussions arising during the 2024 RGS‐IBG Annual Conference session Historical Geographies of the Caribbean and critically contemplates the presence—or not—of Caribbean historical geographies across the historic and contemporary enterprise of British Geography.

Exploring How Affordances of Play Materials Shape Chinese Parents' Interaction With Children: Media‐Elicited Focus Group Discussion

open access: yesChildren &Society, Volume 40, Issue 5, Page 1128-1139, September 2026.
ABSTRACT Existing literature on children's play materials predominantly reflects theoretical frameworks and empirical data generated in the Global North, where ideas of “developmental appropriateness” often overlook the socio‐cultural specificity of materials' affordances and parental expectations.

Weathering above the tides: how iceberg-roll-generated waves shape Arctic rocky shores

open access: yesPolar Research
A significant limitation of the current understanding of cold coast evolution is the paucity of field observations on the development of rocky coasts in glaciated parts of the Arctic.

PERFORMANCE PREDICTION OF CHAIN SAW MACHINES USING SCHMIDT HAMMER HARDNESS

open access: yesBilimsel Madencilik Dergisi, 2018
Schmidt hammer hardness (RL) provides a quick and inexpensive measure of surface hardness that is widely used for estimating the mechanical properties of rock material such as strength, sawability, cuttability and drillability. In this study, RL as predictors, which is thought to be a useful, simple and inexpensive test particularly for ...

Mechanical Properties of Concrete after Replacing Sand Utilizing Fine Aggregates of Brick Powder

open access: yesJournal of Applied Sciences and Environmental Management
Infrastructure and urbanization drive the increasing demand for concrete, which strains natural resources and threatens the ecosystem. Incorporating recycled materials into concrete can fulfill this demand without compromising quality.
