The clearance flow between the nozzle and endwall in a variable geometry turbine (VGT) has been numerically investigated to understand the clearance effect on the VGT performance and internal flow.It was found that the flow rate through turbine increases but the turbine efficiency decreases with height of clearance.Detailed flow field analyses indi
The variability of quasar light curves can be used to study the structure of quasar accretion disks.For example, continuum reverberation mapping uses delays between variability in short and Flexiti long wavelength bands ( short lags) to measure the radial extent and temperature profile of the disk.Recently, a potential reverse lag, where variations
Nowadays, concern over skin cancer has been growing more and more, especially in tropical countries where the incidence of UVA/B radiation is higher.The correct use of sunscreen is the most efficient way to prevent the development of this disease.The ingredients of sunscreen can be organic and/or inorganic sun filters.Inorganic filters Ginger Jar p
A cumulative cutting blasting technology was used for cutting a 20-mm-thick steel plate for the demolition of a steel structure.The main factors affecting the outcome of this approach Flexiti included the opening angle of the liner, the height, and the section form of the charge bed.Based on the theory of linear cumulative cutting, the liner cutter
