The Legacies of Lockdown: Moral Logics of Exchange and Mistrust in Postpandemic China
Economic Anthropology, EarlyView.ABSTRACT When Shanghai entered an extended lockdown under China's Zero‐COVID policy in spring 2022, residents found themselves confined within their residential compounds, cut off from conventional supply chains, and dependent on improvised systems of local provisioning and state rationing. From the perspective of economic anthropology, such conditions

Preliminary analysis of scour due to unsteady plunging jets
, 2018 Scour process due to plunging jets is one of the most relevant topics for hydraulic engineers, especially because of the consequences of an excessive erosion. Generally, a scour process takes place downstream of hydraulic structures and its mechanism and

Laboratory Tests of Scour at a Seawall [PDF]
, 2006 A set of medium-scale laboratory tests of wave-induced scour at seawalls has been performed in a flume at HR Wallingford. The methodology is presented along with test conditions and summarized results.

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.

Flood infrastructure: Localized scour at piano key weirs
, 2020 Historic growth in the US coupled with observed hydrologic changes have created an increased demand for sustainable flood protection. One approach to passing floodwaters is nonlinear weirs such as labyrinth and Piano Key weirs (PK weirs).

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.

The Chemical Record, EarlyView.This publication describes how R. B. Woodward and Roald Hoffmann crafted their masterpiece publications. Illustrations include Woodward's first draft of the famous “Violations There are none. Nor can violations be expected of so fundamental a principle of maximum bonding.” Original but discarded text shows the stepwise paths toward the W‐H masterpieces.
