A Review on Test Facility for Measuring Pressure Drop in Hydroformed Cryopanel
Abstract: Cryopump is a vacuum pump that pumps the gases and vapors by condensing them on a cold surface, by adsorption on porous surfaces or by trapping mechanism. Helium gas which is very light can only be pumped by Cryoadsorption cryopump. Cryoadsorption cryopump cannot be used when working for continuous operation as it pumps the effluent till the saturation state is achieved. Then the absorbed gases are required to be removed …

Urticaria Uncovered: Understanding The Condition And Optimizing Its Management
Abstract: Urticaria, also known as hives, is a skin condition characterized by pale red, raised, and itchy bumps. The name "urticaria" is derived from the Latin words "urtica" and "urere," which mean nettle and to burn, respectively. This skin rash manifests as pink to flesh-colored plaques that are non-pitting and edematous. The primary cause of urticaria is believed to be a condition known as "Fasad e Dam," which refers to blood …

Mn Doping–Induced Enhancement of Ethanol Gas Sensitivity in CuO/Cu₂O/Cu Composites
Abstract: A composite of CuO/Cu2O/Cu was synthesized by heating cupric acetate up to 600 °C for 2 hours in air. The properties of pure CuO films and CuO/Cu2O/Cu films were compared. Films were fabricated by the doctor blade method. Polyethylene glycol was used as a binder to prepare films. Mn was doped to composite to enhance the gas sensing properties. Compositions of Mn doped samples were confirmed using XRFS. According to …
