Implementation of single-use systems in both upstream and downstream applications continues to grow rapidly. Parallel to that growth is the concern about purity levels of polymeric single-use systems because compounds found in disposable materials of construction can leach into process fluids or final drug products. By definition, extractables studies are intended to identify chemical substance...

Paper presents knowledge about types of test in area of materials properties of selected methods of rapid prototyping technologies. In today used rapid prototyping technologies for production of models and final parts are used materials in initial state as solid, liquid or powder material structure. In solid state are used various forms such as pellets, wire or laminates. Basic range materials ...

This paper presents the use of artificial intelligence techniques such as fuzzy logic for nondestructive X-ray testing of various products. The original presented algorithm proposes the defect presence testing in two stages in the radiographic image obtained from the inspected product. The first stage of the algorithm checks whether a possible defect (an area from the radiographic image) corres...

An experiment is described to expose students in a ‘hands-on’ manner to the physics of instrumentation, measurement, electromagnetic radiation and in particular UV radiation. The students will have no difficulty in setting up the apparatus themselves and they will obtain reliable results within a normal school practical period. Additionally, the students will undertake a scientific experiment r...

Objective Roughness is the main parameter in interlocking bonding mechanism. Yet there is no model designed to evaluate the effect of surface roughness on adhesion of coating materials in pharmaceutical sciences. Materials and Methods In this study polymethyl metacrylate spherical beads with different sizes were poured into 10 mm mold, then it was pressed by hand screw and finally heated to 141...

Can FD&C Blue no. 1 dye photoinactivate bacteriophages phi X174, T7, PRD1, and phi 6 under laboratory lighting conditions? At high levels of light, the dye (500 microM) photoinactivated only phi 6. Thus, this dye can be used at concentrations up to 500 microM with bacteriophages phi X174, T7, and PRD1 to test barrier material integrity.
