THE PATTERNS OF CHANGES IN THE DEGREE OF LUBRICATION OF THE CRANKSHAFT BEARINGS OF CAR ENGINES DEPENDING ON THE PARAMETERS OF THE LOAD-SPEED MODES OF OPERATION

The practice of operating machines and mechanisms indicates that bearing wear is one of the main reasons for limiting their durability.This especially applies to the sliding bearings of crankshafts of car engines, where the intensity of wear of their working surfaces significantly depends on the properties of the lubricant.An experimental study of

Abstract Background Gulf War Illness (GWI) remains a serious health consequence for at least 11,000 veterans of the first Gulf War in the early 1990s.Our understanding of the health consequences that resulted remains inadequate, and this is of great concern with another deployment to the same theater of operations occurring now.Chronic immune cell

Hydraulic fracturing and horizontal drilling have increased dramatically in Pennsylvania Marcellus shale formations, however the potential for major environmental impacts are still incompletely understood.High-throughput sequencing of the 16S rRNA gene was performed to characterize the microbial community structure of water, sediment, bryophyte, an
