Abstract. The dynamical contribution of marine ice sheets to sea level rise is largely controlled by grounding line (GL) dynamics. Seroussi et al. (2014) emphasised the sensitivity of numerical ice flow model results to the practical implementation of the friction of the ice on its bed in the very close vicinity of the GL. Elmer/Ice is a reference finite element (FE) ice flow model used in recent marine ice sheet model intercomparison (MISMIP) exercises. In the model, the GL is defined as the nodes where the ice is in contact with the bedrock but belong to both grounded and floating elements. Inherently to the FE method, computing the contribution of the friction by element requires evaluating the friction at the integration points. In Elmer/Ice, this is done by interpolating the values of the friction parameter C prescribed at the nodes. In this brief communication, we discuss and compare three alternative ways to prescribe the friction at the GL: (i) C is prescribed and non null at the GL nodes, (ii) C is set to zero at the GL nodes, and (iii) C is discontinuous at the GL nodes (i.e. is prescribed and non null for grounded elements and otherwise null). So far, all published results using Elmer/Ice were obtained with the first method. Using the MISMIP3d diagnostic experiment, we first show that, although the change in the total force at the base is insignificant, the three methods lead to significantly different velocity fields. We then show that these methods also lead to different steady state GL positions and different transient behaviours. Such model sensitivity to the methods discussed here is certainly specific to the high friction prescribed in the MISMIP experiments and should be smaller in real setups where friction in the vicinity of the GL would be expected to be lower. Results obtained with the three methods are available as Supplement for future comparisons.

The article presents a methodology for diagnosing experimentally identifying a vivid vividness of the formations of creative self-realization of the magistrates of the musical mystery in the process of the choir-choir movement. Today’s master student of musical mystery in Prague has expanded the horizons of musically-vikonavsky, musically-creative talents, be aware of alternative musical and pedagogical activities, deny your own selfrealization, and learn more about the Criteria have been introduced to the testimonials of the pre-approved approval. The following methods were implemented: methods of nutrition, ranking; diagnostic experiment. By a method of conducting a diagnostic experiment, a voucher of a vivid vividness of the formations of creative selfrealization of magistrates of a musical mystery was formed. So, we conducted a questionnaire with masters of the musical mystery in order to ensure that they are put before creative self-realization. Dalі, the students were blown away for profiling, according to the world’s significance, the components of creative self-realization (cognitivemotivational, gnostic-tsilovy, communicative-constructive, techno-design, creative-design). There was a great deal of discussion with the knowledge of respondents from day to day, the significance of the structure of the previous construct. Prospects for fake science rozvidok vbacha вmo in the development of experimental models of creative self-realization of magistrants of musical mystery. From now on, an analysis of the results of our achievement so that I can actualize respect for the fact that the period of fierce joining the masters of the musical mystery is characterized by their need for creative self-realization. Vrakhova’s students, on purpose, looked at selfsustainability and student initiative, as well as indicators of their creative self-realization from the choir choir.

Study aim: to study the level of future Music teachers’ instrumental-performing preparedness to innovation activity in order to determine the ways of its optimization.Material and methods: The pedagogical experiment was carried out at the Institute of Arts of the National Pedagogical Dragomanov University and at the South Ukrainian National Pedagogical University after K.D. Ushynsky. 326 students of Bachelor degree specializing in Music took part in the diagnostic experiment aimed to define the level of their instrumental-performing readiness to perform innovation activity. Results: The criteria to define the formed level of future Music teachers’ readiness to perform innovation activity have been developed: motivation-value; competence-orientation; reflexive-empathy; creative-technological; projective-activity. In accordance with the developed component structure and criteria of instrumental and performing training of future Music teachers, 3 levels of students’ preparedness to perform innovation activity have been described: high, medium and low levels. The statistical data showed the insufficient level of the students’ preparedness for instrumental-performing innovation activity.Conclusions: The results prove the need to make the model for preparing future Music teachers to innovative instrumental-performing activity.

The Korea Astronomy and Space Science Institute (KASI), in collaboration with the NASA Goddard Space Flight Center (GSFC), has been developing a diagnostic coronagraph to be deployed in 2023 on the International Space Station (ISS). The mission is known as “Coronal Diagnostic Experiment (CODEX)”, which is designed to obtain simultaneous measurements of the electron density, temperature, and velocity in the 2.5- to 10-Rs range by using multiple filters. The coronagraph will be installed and operated on the ISS to understand the physical conditions in the solar wind acceleration region and to enable and validate the next generation space weather models.
