Background: Upconverting nanophosphors (UCNPs) are composed of certain nanosized inorganic host materials doped with specific rare earth ions.They exhibit the phenomenon of photon upconversion, whereby the sequential absorption of two or more low energy photons is followed by luminescent emission of multiple photons with higher energy.In addition,
Clinical optimism for dendritic cell vaccination against ovarian cancer has been tempered by the knowledge that tumors avail themselves of multiple mechanisms of immune Vitamins for Kids evasion, thus blunting the efficacy of therapeutic vaccination.Mechanisms of immune suppression include infiltration by regulatory T cells (Treg) and myeloid suppr
The flare, which aims to burn all kinds of waste gas produced by petrochemical enterprises, is an important facility for plants to keep safe and prevent harming the environment.However, when the exhaust gas is not sufficiently burned, black smoke will be produced in the flare system and endanger Primary Electrical Wires air quality and human health
Many, if not all of the oil and gas fields under development, have leaking wells.There are a lot of so-called abandoned, ownerless wells.Subsoil users, by one way or another, make efforts to eliminate leakage in such wells.At the same time there are no universal and reliable techniques.The problem of well leakage is seriously increasing when wells
Ultra-wide band (UWB) antennas with transparent indium zinc tin oxide (IZTO)/Ag/IZTO multilayer electrode films are presented.The geometry of the radiator of the proposed UWB antenna is a simple semicircular shape, and acryl is used for the transparent substrate.Three types of proposed antennas are used for the comparison: first, an UWB antenna wit
