Sterilization installation electron beam dynamics optimization
Some methods to increase efficiency of electron beam usage in sterilization installation, simulated by computer code “Beam Scanning”, are presented. These methods include a correction of the current waveform in deflecting magnet, forming slightly convergent electron flow and irradiation of lateral object sides by low-energy electrons in the energy spectrum.

Old topics, old approaches? ‘Reception’ in television studies and music studies
The question of reception is closely linked to the history and the roots of audience studies. But what is ‘reception’ and what exactly does it mean? As audience studies have developed from a contested novelty to a now established academic field, what do we do with a concept that defined our interests in the past and may now be too wide or even obsolete? This article deals with this issue by mapping how the concept of reception was conceptualized and researched in audience studies of the past ten years, with a focus on studies of music and studies of television. We find that in music, strong focus remains on music reception in the context of performances and events, and this lies in contrast to a small number of studies which instead focus on a framework of music in ordinary life and the audiences’ contextual localities. Concerning reception of television, much of the scholarship starts from the cultural studies tradition and looks at television viewing as a means to construct identities. Discussing these findings, we inquire whether the hybridization of media also implies a hybridization of research traditions and methodologies, and what consequences it has for the balance between textual, production and audience approaches.
