Evaluation of Lubricant Selection and Lubrication Intervals for Pin–Bushing Bearings Operating Under High-Temperature Conditions in Heavy-Duty Construction Machinery

Lubricants
Pin–bushing bearings in heavy-duty construction machinery operating in severe industrial environments are susceptible to accelerated wear, grease degradation, and lubrication failure, yet application-specific guidance for lubricant selection and re ...

Evaluating the suitability of six hydrophobic natural eutectic solvents as the internal phase in a cosmetic cream formulation

International Journal of Cosmetic Science, EarlyView.
Hydrophobic natural eutectic solvents can function as structural oil phase substitutes in creams prepared by low‐energy processes, enabling sustainable, regulation‐compliant formulations with desirable sensory profiles. Abstract Objective This work evaluates whether hydrophobic natural eutectic solvents can replace the conventional oil phase in ...

Assurance of lubricant supply in wet-lubricated space bearings [PDF]

, 1976
Conventional lubrication techniques appear to be satisfactory, but rigorous proof of meeting a ten-year life requirement is lacking. One approach provides additional lubricant only when commanded from ground control, while the other passively augments ...

Waking a Dormant Legal Resource: Institutional Activation and the Origins of Important Projects of Common European Interest

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.

On the Necessary but Sufficient Amount of Grease to Obtain Fully Lubricated Fretting Regime in Moist Air for SUJ2 Bearing Steel against S15C Carbon Steel

Tribology Online, 2013
Influence of the moist air humidity (10-70%) on the fretting characteristics of steels under grease lubrication is experimentally investigated. Ball (bearing steel, JIS SUJ2) on disk (carbon steel, JIS S15C) type fretting tests for 0-20 mg of grease ...
