Performance of large-bore tapered-roller bearings under combined radial and thrust load at shaft speeds to 15,000 rpm [PDF]

The performance of 120.65-mm bore tapered roller bearings was investigated at shaft speeds up to 15,000 rpm. Temperature distribution and bearing heat generation were determined as a function of shaft speed, radial and thrust loads, lubricant flow rate ...

‘The Good Couscous That Pleases Us!’: The Meanings of Enduring Imperialist Imagery in Postcolonial French Food Advertising, 1970–2000

Gender &History, EarlyView.
ABSTRACT This article examines a wave of Orientalism‐inspired food commercials that appeared on television in France between 1975 and 2000. Older commercials for couscous were more banal, emphasizing a given product's superiority or affordability. Around 1975, however, there was a concerted shift in the advertising; new spots contained exoticized ...

Technology for Whom and for What? A Global South View of Tech Diplomacy

Global Policy, EarlyView.
ABSTRACT International politics is linked to its technical‐social character. Also, technology is socially constructed and thereby not entirely neutral or impartial. A tech‐driven geopolitical landscape has been a defining feature of contemporary world politics.

Distinct regional patterns of synaptic vulnerability across hippocampal and parahippocampal subregions in Alzheimer's disease

Brain Pathology, EarlyView.
Synaptic loss in Alzheimer's disease predominantly affects the entorhinal cortex and parahippocampal gyrus. Amyloid‐β and p‐tau pathology show global associations with synaptic density but are limited in specific subregions. Instead, axonal damage associates with synaptic loss locally and in interconnected subregions.

Prevention of microglial activation and postoperative cognitive deficits by positive allosteric modulation of α5‐GABAA receptors

British Journal of Pharmacology, EarlyView.
Background and Purpose Long‐lasting cognitive deficits after surgery in aged individuals, referred to as perioperative neurocognitive disorder (NCD), are a significant public health concern. Such postoperative cognitive deficits are dependent on the presence of microglia in the brain, which, when activated, trigger neuroinflammation.
