Legacy effects of redlining on the distribution of greenspaces in US cities

Frontiers in Ecology and the Environment, EarlyView.
We investigated how a discriminatory housing policy—redlining—has shaped the spatial patterns and configurations of greenspaces throughout 177 cities in the contiguous US. Housing segregation has been a long‐term development practice that has sequestered communities of color to areas with elevated environmental and public health risks.

Differential Associations Between Relational Health and Mental Health Among Civilian and Military‐Affiliated Samples Reporting Moral Injury

Journal of Counseling &Development, EarlyView.
ABSTRACT The symptoms of anxiety and depression are commonly reported within military‐ and non‐military‐affiliated populations, with considerable evidence available to counselors regarding which relational characteristics function as protective factors among these populations.

COMPARATIVE ANALYSIS AND EVALUATION OF THE CONVERSION FORMULA FOR REBOUND NUMBER OF SCHMIDT HAMMER TEST AND UNCONFINED COMPRESSIVE STRENGTH TEST – CASE STUDY: ANDESITE ROCK SLOPE IN GRAHA PUSPA, LEMBANG FAULT

Rudarsko-geološko-naftni Zbornik
The Unconfined Compressive Strength (UCS) test is one of the most common methods for determining the rock material strength value. However, the size and complexity of the instrument do not allow UCS testing to be carried out in the field.

HIGH SELECTIVE OIL SHALE MINING; pp. 305–325 [PDF]

Oil Shale, 2013
Several extraction technologies have been used for mining oil shale in Estonia. The quality and properties of the raw material for fuel and oil depend directly on the initial geological properties of the mineral resource.

New Schmidt hammer exposure‐age dating calibrations for the Last Glacial Termination in NW Scotland: Development and application to undated Torridon Group sandstone surfaces in Wester Ross

Journal of Quaternary Science, EarlyView.
ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.

Large water-hammer pressure for column separation in pipelines [PDF]

, 1991
Water-hammer pressures in a pipeline due to the collapse of a vapor cavity adjacent to a valve are investigated. A water-hammer event is initiated by the closure of a valve in a simple reservoir-pipeline-valve system.

The stone in a monumental masonry building of the Tyrrhenian coast (Italy): new data on the relationship between stone properties and structural analysis

Ge-conservación, 2017
In order to assess physical-mechanical properties of building material (“Fuscaldo sandstone”), non-destructive tests have been performed in the main façade of “Palazzo Carelli - Pignatelli” (14th-15th centuries) in Fiumefreddo Bruzio (Italy), situated in

Education for Problems of Sustainable Development

Sustainable Development, EarlyView.
ABSTRACT The Cynefin framework for decision‐making categorizes problem environments into simple (known knowns), complicated (known unknowns), complex (unknown unknowns), and chaotic (unknowables). Simple and complicated problem environments enable best and good solutions, but complex and chaotic problem environments require emergent and novel solutions.

Phase Transformation Behavior of Continuously Cooled Fe–C–V–(Mo) Alloys

steel research international, EarlyView.
Additions of vanadium and molybdenum microalloying are shown to reshape phase transformations in clean low‐carbon steels. By tracking microstructural shifts during continuous cooling, the work uncovers the correlation between transformation kinetics, ferrite morphology, and hardness.
