Empirical Physics‐Based Normal Behavior Modeling of Drive Train Temperatures With High‐Resolution Wind Turbine Operating Data

Wind Energy, EarlyView.
ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

The agency of a marmalade machine: Gender, class and mechanical gadgets in the British Kitchen, c.1870–1938

Gender &History, EarlyView.
Abstract This article explores the marmalade machine, a mechanical device designed to slice orange peel. These niche objects were manufactured between roughly 1870 and 1938 in Britain. As a so‐called ‘labour‐saving’ gadget, the marmalade machine sliced orange peel quickly and effectively, removing the tedious process of slicing orange peel by hand ...

The Impact of Midwife Experience and Time of Birth on the Risk of Obstetric Anal Sphincter Injuries (OASIS)

Birth, EarlyView.
Background: Obstetric anal sphincter injuries (OASIS) are a significant complication of vaginal birth. Methods: This retrospective cohort included 13,651 term spontaneous vaginal deliveries at a single medical center (2020‐2025). Midwife experience (early, mid, and highly experienced), shift timing, and OASIS incidence were analyzed.
