Recovery and restoration potential of cold‐water corals: experience from a deep‐sea marine protected area

Restoration Ecology, Volume 31, Issue 8, November 2023., 2023
Cold‐water corals (CWCs) are important species that provide habitat for other taxa but are sensitive to mechanical damage from bottom trawling. CWC conservation has been implemented in the form of marine protected areas (MPAs), but recovery from impact may be particularly slow in the deep‐sea environment; consequently, the use of restoration techniques

Data‐driven prediction of room‐temperature density for multicomponent silicate‐based glasses

Journal of the American Ceramic Society, Volume 106, Issue 7, Page 4142-4162, July 2023., 2023
Abstract Density is one of the most commonly measured or estimated material properties, especially for glasses and melts that are of significant interest to many fields, including metallurgy, geology, materials science, and sustainable cements. Here, three types of machine learning models (i.e., random forest [RF], artificial neural network [ANN], and ...

Investigating the Feasibility of Using Concrete Containing Waste Paper Sludge Ash and Pozzolanic Materials to Repair Bridge Stub Columns

Advances in Civil Engineering, Volume 2023, Issue 1, 2023., 2023
In most cases, the bridge columns are underwater, and there is a risk of corrosion. The columns of marine structures and docks also include such problems. In addition to the problem of environmental hazards, the bridge columns may fail due to design problems or increasing needs.
