Design of a test rig for grease endurance tests
Results in EngineeringBackground: The performance and endurance of lubricating greases is often assessed through model tests (like four-ball tests or SRV tests). This approach has some limitations, especially when greases with special fillers are investigated, because ...

Moisture tempers impairment of adult Otiorhynchus sulcatus (Coleoptera: Curculionidae) climbing ability by fluoropolymer, talc dust, and lithium grease [PDF]
, 2005 As part of a project to develop tools for the physical exclusion of flightless root weevils, adult black vine weevils (BVW), Otiorhynchus sulcatus (F.), were placed in open enclosures with smooth walls of glass, plastic or aluminum to test their ability ...

JCMS: Journal of Common Market Studies, EarlyView.ABSTRACT Important Projects of Common European Interest (IPCEIs) have become a central tool of the European Union's (EU) new industrial policy. IPCEIs derive their peculiar name from an exemption to the general prohibition on state aid that has existed since the Treaty of Rome but has only led to the creation of a stand‐alone policy instrument in 2014.

When Do Citizens Support Corrupt Politicians? The Trade‐Offs Between Corruption and Competence
Public Administration Review, EarlyView.ABSTRACT The intriguing paradox of wide public disdain for corruption alongside popular corrupt politicians exists globally. By speaking to public ethics theory and rational choice theory, this study examines the trade‐off in which citizens tolerate corrupt officials in exchange for their competence to deliver public benefits.
