In his novel The Glass Bead Game, Hermann Hesse introduces an essentially cosmic game within a symbolical Universe which recently has been compared with a „neuronal network of the cosmic mind“. In his game all those games which are known to us today appear to be summarized. Hence, by closer inspection, the glass bead game shows up as a meta-game, a proto-game, and as a playful paradigm of playi...

Currently available non-invasive clinical methods for diagnosing osteoporosis are mainly associated with ionizing radiation. Ultrasonic assessment of bone disease is a more recent technology. A theoretical explanation for the relationship between ultrasonic parameters and bone structure is necessary. Thus, two types of bone samples of perspex (HAP) and perspex-glass beads were produced. Ea...

Abstract Hydraulic fracturing is a widely employed well stimulation technique in which synthesized fracking fluid pumped into the bore at high pressures to propagate fractures rock formation matrix for hydrocarbon production. Proppant being one of essential component used keep hydraulically induced open and conductive by acting as mechanically strong support particle. operations are gradually s...

Different techniques were compared for their effectiveness in the disruption of the rigid cell walls of Basidiomycetes. Grinding under liquid nitrogen, stirred glass bead milling and enzymatic cell lysis were applied to the mycelia of Pleurotus sapidus and Lepista irina grown submerged. Each of the disruption procedures was evaluated by testing the quantity and quality of released intracellular...

Background A novel technique of sterilization of endodontic files is introduced in this article. Aims Newly introduced sterilization unit, named "SteriFast" is compared with autoclave and glass bead sterilizer using biological indicator. Materials and Methods Spore strips of Bacillus pumilus were cultured in nutrient broth. This cultured media was used to contaminate the experimental sample...
