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 Reveal the Shield 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 expe

In this study, the effect of ulexite substitution in cement mortar and its physical and mechanical properties on cement mortar properties were investigated.First of all, the pozzolanic activity of the ulexite material was determined.Then, cement mortars with ulexite additives at different rates (0.5%, 1%, 2%, 4%); Specific gravity, specific surface

BackgroundIn October 2009, the French government organized a national-wide, free of charge vaccination campaign against pandemic H1N1 influenza virus, especially targeting pregnant women, a high risk group for severe illness.The study objective was to evaluate pandemic flu vaccine uptake and factors associated with non-vaccination in a population o

The retinal pigment epithelium (RPE) is a neural monolayer lining the back of the eye.Degeneration of the RPE leads to severe vision loss in, porta abito so far incurable, diseases such as age-related macular degeneration and some forms of retinitis pigmentosa.A promising future replacement therapy may be autologous iris epithelial cell transdiffer

Tuberculosis being endemic in country like India can affect any organ though pulmonary tuberculosis is rampant and extrapulmonary is rare.Tuberculosis affecting parotid gland is a rare occurrence, usually unilateral.However, Mycobacterium tuberculosis causing cold abscess in bilateral parotid glands is even rarer.Here, we present a case of a young
