MODIFICATION OF POSS AND THEIR TRIBOLOGICAL PROPERTIES AND RESISTANT TO SPACE ATOMIC OXYGEN IRRADIATION AS LUBRICANT ADDITIVE OF MULTIALKYLATED CYCLOPENTANES

Abstract Developing functional additive resistant to space atomic oxygen (AO) irradiation through simple molecular design and chemical synthesis to enhance the lubricating performance of multialkylated cyclopentanes (MACs) oil is a significant challenge.Herein, sulfur-containing polyhedral oligomere silsesquioxane (POSS) were synthesize via a click

Record linkage is the click here process of identifying and merging records across different databases belonging to the same entity.The health sector is one of the pioneering areas of record linkage techniques applications.In 1998 we began the development of a software package, called RecLink that implemented probabilistic record linkage techniques

Gestational protein restriction was associated with low birth weight, hypertension and higher prevalence of cardiac disorders in adults.Several mechanisms, including epigenetics, could be related with the cardiovascular phenotype on protein-restricted offspring.Thus, we investigated the morphological cardiac effects of gestational protein restricti

The article is aimed at the research of the influence of stiffness characteristics included in a model of a railway track, which is the part of a multibody system.The other part of the multibody model is a railway vehicle.Authors are focused on the investigation of response of some selected output parameters under various values of input of stiffne

The tundish prevents unsteady flow affecting on the steel cleanness and temperature.The presented article offers sten jacket m a new design of a ladle shroud (LS) with three holes placed in a special dome (separating the steel flow) steeped in a metal bath.Various options of the LS construction were analysed, as well as its positioning in the tundi
