Groundwater Connectivity and Buffering in Western Australian Hypersaline Lakes: Implications for Late‐Stage Martian Lacustrine Systems

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Thousands of saline to hypersaline lakes exist across the Yilgarn Craton in Western Australia, representing potential Mars analogs with diverse and varying salinity, pH, and oxygen conditions that remain poorly constrained. Here, we report geochemical trends in lake waters that vary across wet‐dry cycles as well as with regional location and ...

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

International 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 ...

Drilling the Marathousa palaeo‐lake in Greece (Peloponnese): inferring the environmental context of a Middle Pleistocene archaeological site

Boreas, Volume 55, Issue 3, Page 866-884, July 2026.
The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.

Waking a Dormant Legal Resource: Institutional Activation and the Origins of Important Projects of Common European Interest

JCMS: Journal of Common Market Studies, Volume 64, Issue 4, Page 1359-1381, July 2026.
ABSTRACT Important Projects of Common European Interest (IPCEIs) have become a central tool of the European Union's (EU) new industrial policy. IPCEIs derive their peculiar name from an exemption to the general prohibition on state aid that has existed since the Treaty of Rome but has only led to the creation of a stand‐alone policy instrument in 2014.

Anti‐Black Racism in Nursing in Canada and Black Nurses' Resistance: An Analytic Review of Newspaper Coverage, 1940s–2020

Nursing Inquiry, Volume 33, Issue 3, July 2026.
ABSTRACT Black women's participation in nursing in Canada has been marked by a long history of discrimination and exclusion, even after they were formally permitted to enter the profession in the mid‐1940s. Examining mainstream Canadian newspaper coverage, this study traces anti‐Black racism in Canadian nursing from the 1940s to 2020.

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

Polar 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

Bilimsel 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 ...
