Scour Depth Around Cylinders Under Combined Effects of River Flow and Tidal Currents

Journal of Marine Science and Engineering
The safety of coastal structures is a growing global concern due to the combined effects of strong tides and river flow. In this study, the local scour around cylinders under the influence of tides combined with river flows was investigated numerically ...

Camels as a Climate‐Resilient Linchpin for Sustainable Development in Global Drylands

Sustainable Development, EarlyView.
ABSTRACT Camels represent a significant, yet underutilized, asset for advancing integrated sustainable development in the world's expanding drylands. Previous reviews have examined camels' physiology, milk composition, or pastoral systems in isolation; this review examines their potential as a climate‐resilient linchpin for food systems by synthesizing

Effective Equilibrium Reaction Zone Modeling of Hydrogen Plasma Smelting Reduction: A Scenario Analysis

steel research international, EarlyView.
The study presents a dynamic zonal model for hydrogen plasma smelting reduction (HPSR) in direct current arc furnaces, predicting time‐dependent behavior of metal, slag, and off‐gas. The study considers various industrial scenarios to quantify energy demand, hydrogen utilization, degree of reduction, and other operational sensitivities.

Enteric diseases in pigs from weaning to slaughter [PDF]

, 2003
The general aim of this thesis was to study enteric diseases in growing pigs, with special reference to diseases caused by Brachyspira hyodysenteriae and Lawsonia intracellularis. The occurrence of enteric diseases in “growers” is a problem of increasing

Mechanics‐based model for cold joints in reinforced concrete members

Structural Concrete, EarlyView.
Abstract This study introduces a mechanics‐based numerical model to characterize the behavior of cold joints in reinforced concrete members subjected to monotonic loading. The model incorporates mechanisms such as interface slip and opening, aggregate interlock, clamping force, and dowel action of the reinforcing bars crossing the interface.

Estimation of Local Scour Dimension below Siphon Spillway with the Ski-jump Bucket Energy Dissipater Using the Group Method of Data Handling (GMDH)

علوم آب و خاک, 2018
The investigation of local scour below hydraulic structures is so complex that makes it difficult to establish a general model to provide an accurate estimation for the local scour dimension.

Impact behavior of a strengthened bridge substructure under scour and vessel collision

Case Studies in Construction Materials
When subjected to a vessel collision in the presence of scour induced by wave-current or flood, a bridge can sustain more severe damage compared to the pristine bridge undergoing the same impact.
