Monitoring of historical structural materials with computed tomography

Structural Concrete, EarlyView.
Abstract Computed tomography (CT) is an excellent tool to solve certain engineering problems connected to material science (such as sulfate swelling, internal degradation due to freezing, and alkali silicate swelling) and to understand specific processes (frost peeling, acid action).

New insights from the bias-corrected simulations of CMIP6 in Northern Hemisphere’s snow drought

Communications Earth & Environment
Recent decades have witnessed increasing snow droughts in the Northern Hemisphere, yet reliable future projections remain challenging due to biases in climate models.

Snow-Water Equivalent Observation by Pressure Pillow

Journal of the Japanese Society of Snow and Ice, 1977
During the period from 26 November 1976 to 10 May 1977, a continuous observation of snow-water equivalent by the use of surface-mounted type pressure pillow 2. 4 m in diameter, mounted on ground surface. was carried out at Hassaki, Yunotani-mura, Kitauonuma-gun, Niigata-ken, Japan.The inner pressure of this pillow was measured electrically by a ...

The “We” and “Me” of Identity in Hazardous Industry Organizations: Face Work Tactics Among Practicing Engineers

Symbolic Interaction, EarlyView.
In this paper, we use Goffman's notion of “face work” to examine how pipeline engineers perform and present their working selves as competent experts. Our analysis identifies various faces and face work tactics, including a focus on professional judgment, actively selling one's expertise relative to others, protective self‐deprecatory strategies, and ...

Unusual vertical oscillations of a radiosonde

Weather, EarlyView.
In summer 2023 in southern England, several unusual balloon launches were observed which descended for a few minutes before resuming ascent. This unusual vertical oscillation was repeated several times in a ‘roller‐coaster’‐like pattern. This article discusses the behaviour of the balloons.

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

Wildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.

Strategies for using remotely sensed data in hydrologic models [PDF]

Present and planned remote sensing capabilities were evaluated. The usefulness of six remote sensing capabilities (soil moisture, land cover, impervious area, areal extent of snow cover, areal extent of frozen ground, and water equivalent of the snow ...

The effects of moose and pine density on browsing damage in Swedish pine forests

Wildlife Biology, EarlyView.
Moose Alces alces is a culturally and economically important game species in Sweden, but their browsing on regenerating Scots pine trees Pinus sylvestris often causes extensive damage to the production and quality of timber. Forest and wildlife managers are faced with the dilemma of how to reduce damage to timber trees while also supporting moose ...

Estimating Daily Snow Density Through a Spatiotemporal Random Forest Model

Water Resources Research
Snow density is of paramount importance in water resource management, snow avalanche warning, and climate change research. However, the lack of competent methods for long‐term and vast‐scale snow density mapping persists due to the intricate ...
