In this paper, the necessary grey sns nails in-cylinder conditions for the transition from spark ignion (SI) to homogeneous charge compression ignition (HCCI) are analyzed.The hereby important factors for ignition time are investigated analytically.A control oriented combustion model, that is validated by experimental data, is used for sensivity an
The purpose of the work is to study the influence of the control of the elastic and damping characteristics of the cushioning system based on the use of magnetorheological elastomers on the smoothness of the course of wheeled transport vehicles.The technique.The research used the methods of: magnetic field theory, the theory of vehicle suspension,
We evaluated the influence of photoactivation method and hydrophobic resin (HR) application on the marginal and internal adaptation, hardness (KHN), and crosslink density (CLD) of a resin-based fissure sealant.Model fissures were created in bovine enamel fragments (n = 10) and sealed using one of the following tinsupe protocols: no adhesive system
A jumbo tuz de?irmeni novel innate immune strategy, involving specific cholesterol oxidation products as effectors, has begun to reveal connections between cholesterol metabolism and immune response against viral infections.Indeed, 25-hydroxycholesterol (25HC) and 27-hydroxycholesterol (27HC), physiologically produced by enzymatic oxidation of chol
