Pm's Explanation. Pm: I chose flat files to store PmWiki pages because I haven't seen any real advantages of using a database, and there are definitely some disadvantages. For the standard operations (view, edit, page revisions), holding the information in flat files is clearly faster than accessing them in a database, and with page caching abilities (coming soon) it'll be even faster.
FIELD: physics. SUBSTANCE: radiation-sensitive detector includes a photosensor element (122) and a scintillator (116) optically connected to the photosensor element (122). The scintillator (116) includes a powdered scintillator and a resin mixed with the powdered scintillator. The resin includes one of a polyepisulphide, a sulphur-based polymer or polycarbodiimide.
FIELD: construction. SUBSTANCE: method includes introduction of heat-resistant accelerant and liquid medium into the first mixing device, their mixing to make suspension of heat-resistant accelerant. Aqueous suspension of calcined gypsum is produced in the second mixing device. Aqueous dispersion is loaded from the second mixing device into drain apparatus.
