In recent years, with the Cot Mobile development of micro/nanoelectromechanical systems (MEMS/NEMS), the demand for efficient lubricants of silicon surfaces intensified.Although the use of ionic liquids (ILs) as additives to base oils in the lubrication of steel/steel or other types of metal/ metal tribological pairs has been investigated, the numb

Magnetorheological (MR) fluid devices are widely used in active automotive control applications.However, MR fluid-based valve actuators are not in the limelight.This paper proposes a new flexible valve train with an MR fluid control system; the valve train can enhance the performance of internal combustion engines.A major component of this valve tr

We previously demonstrated that cholesterol deprivation increases Phones endothelial cyclooxygenase-2 (COX-2)-dependent prostacyclin [prostaglandin I2 (PGI2)] production in vitro.Cholesterol directly regulates gene transcription through the sterol response element binding protein (SREBP).In this work, we demonstrate that SREBP directly regulates CO

The TABLE Danube Delta, one of the most important wetlands in Europe, went through many transformations during the last century, mainly due to human interference.When analyzing the current state of this ecosystem, one must consider the historical changes that have a significant influence on the evolution of the delta.Written documents are, no doubt
