The gas puff imaging diagnostic is used for the investigation of the poloidal flow and turbulent fluctuations at the plasma edge and scrape-off layer (SOL) on the HL-2A tokamak.The impact of resonant magnetic perturbations (RMPs) on the edge poloidal velocity ( ${V_ heta }$ ) are investigated and compared during the operation of a stair-like rising
A new theoretical model to predict the build-up of scaling on the heat transfer surface of coolers is developed.Scaling fouling is originated as a layer of crystals of inverse solubility salts such as calcium carbonates present in cooling water, is formed on the heat transfer surface.Even though fouling cannot be fully avoided, its detrimental effe
Reverse transcriptase (RT) from the human immunodeficiency virus continues Din Rail to be an attractive drug target for antiretroviral therapy.June 2022 will commemorate the 30th anniversary of the first Human Immunodeficiency Virus (HIV) RT crystal structure complex that was solved with non-nucleoside reverse transcriptase inhibitor nevirapine.The
To form functional neuronal connections, Desk and Hutch axon outgrowth and guidance must be tightly regulated across space as well as time.While a number of genes and pathways have been shown to control spatial features of axon development, very little is known about the in vivo mechanisms that direct the timing of axon initiation and elongation.Th
The rubber tyred metro has three-series suspension systems and two sets of running systems, namely rubber wheels and steel wheels.The steel wheels, as safety wheels, only function in the event of tyre burst and turnout passing.In normal running, the steel wheels have no contact with the rail, so the calculation formula of the flexibility coefficien
