The article describes a process of glass fiber production, technological properties of glass fiber, and areas of its industrial application. The operating principle of the M7213 detector scintillation probe (Mesacon Messelektronik, GmbH Dresden) level detector is described. It contains a block of a radioactive source ionizing radiation of Cs-137, a block for recording gamma radiation (detector) and a block for processing information indicating the level of glass mass in the preliminary…

Bubble Theory is introduced as a boundary-centric relational framework in which physical systems are modeled as localized, self-maintaining regions (“bubbles”) whose boundaries encode interaction, information flow, and dynamical constraints. A boundary operator B is defined to capture deformation, coupling, and stability, leading to a general dynamical law for bubble evolution and exchange flux between interacting systems. Worked examples—including spherical and toroidal geometries and a…
