In Situ Observation of Transient Responses in Grease Lubrication by Micro Infrared Spectroscopy
In situ observation of lubricant films formed with greases was carried out at EHL conditions with a micro-FTIR. Three urea compounds were used as a thickener and 12 mass percent of the thickener was added in PAO, respectively. From the IR spectra, CH and

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

When Do Citizens Support Corrupt Politicians? The Trade‐Offs Between Corruption and Competence
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.

This work explores the use of various fillers, including eggshell powder, feather meal, peanut hulls, and sawdust to reinforce a base binder GFS90 (comprised of 90 wt.% sulfur, 5 wt.% chicken fat, and 5 wt.% sunflower oil). The resulting composites showed impressive compressive strengths ranging from 15.3 to 36.2 MPa, making them a potential ...
