Abstract:
Abstract During the twentieth century, scholars attempted to date early astronomical instruments by the scientific information discernable in their design. In particular, they devised “methods” to date planispheric astrolabes by the position of the vernal equinox on the calendar scale or by the precessional effect over the star coordinates. Such methods usually overlooked the many problems behind the instruments’ design and construction and the vicissitudes in a particular object’s history. Criticisms of the naiveté of the scientific approach did not persuade scholars with an astronomical back

Aim/Purpose: Quality in higher education assumes the challenge of developing in all citizens of the 21st century the cognitive, motivational, and socio-cultural dimensions that provide them with communication competences including the use of information and communication technologies, for the dissemination of sustainable scientific knowledge in different languages. Hence this paper evaluates a didactic-technological process called “Ensayo Científico Multilingüe” or ECM (“Multilingual Scientific Essay”), which guides the construction of argumentative texts in a shared didactic space in the nati

Abstract:
The fixed-energy window scan approach, for both elastic and inelastic modes, is a valuable tool to discriminate between motions activated when dynamical phase transitions occur in a sample as a function of time, temperature, pressure, electrical field or illumination. Considering that, on one hand, such variations can generate a weak signal, and on the other, high data throughput makes it possible to screen many samples during a beam time, pulse multiplication is an ideal strategy to optimize the intensity of the analyzed signal. To ensure this capability, a proposal for a future upgrade of MI

Background. The article deals with the interaction of the constructive evolution of the instrument and the development of bassoon performing of the 16–17 centuries. The aesthetics of that time was associated with the search for new expressive means, realization of which could be ensured by new instruments with rich and expressive sound. One of such instruments is bassoon; it was during the Baroque era when the bassoon took its shape and the sound image we know today. Thanks to technical evolution, the instrument acquired new artistic capabilities and new sound quality. A new repertoire was for

The baroque music occupies a leading position in the field of instrumental performing as an obligatory part of the educational (works by J. S. Bach) and concert repertoire. The problem of interpretation of early music, acutely posed by musicians of the XX century – up to the reconstruction of all historical performance parameters – retains its relevance. In this
