Opis:: The article deals with a need to introduce complex preparation for solving educational situations at university faculties educating future teachers, social educationalists and educators. It defines the terminology of an educational situation and shows possibilities of how to solve educational situations in theory as well as in practice under university conditions both from the point of view of practical realisation and research into given problems.

Tytuł:: Myosin molecule packing within the vertebrate skeletal muscle thick filaments. A complete bipolar model*

cross-bridge action
Opis:: Computer modelling related to the real dimensions of both the whole filament and the myosin molecule subfragments has revealed two alternative modes for myosin molecule packing which lead to the head disposition similar to that observed by EM on the surface of the cross-bridge zone of the relaxed vertebrate skeletal muscle thick filaments. One of the modes has been known for three decades and is usually incorporated into the so-called three-stranded model. The new mode differs from the former one in two aspects: (1) myosin heads are grouped into asymmetrical cross-bridge crowns instead of symmetrical ones; (2) not the whole myosin tail, but only a 43-nm C-terminus of each of them is straightened and near-parallel to the filament axis, the rest of the tail is twisted. Concurrent exploration of these alternative modes has revealed their influence on the filament features. The parameter values for the filament models as well as for the building units depicting the myosin molecule subfragments are verified by experimental data found in the literature. On the basis of the new mode for myosin molecule packing a complete bipolar structure of the thick filament is created.

Tytuł:: Mathematical modelling of elastic deflection of a tubular cross-section
Autorzy:: Zastempowski, M.
Bochat, A.
Powiązania:: https://bibliotekanauki.pl/articles/258496.pdf
Data publikacji:: 2015
Wydawca:: Politechnika Gdańska. Wydział Inżynierii Mechanicznej i Okrętownictwa
Tematy:: mathematical modelling of elastic deflection
tubular elements
deflection of ring under action of external forces
Opis:: Cutting a tubular element into thin rings is an operation often used in engineering processes. Total work of the cutting consists of that necessary for initial deflection of cut material and the cutting work itself. This paper presents mathematical models which describe deflection of cross-section of a single tubular element as well as a single layer of tubes under action of external forces ( acting and reacting ones). The deflection concerns end part of tube hence the cutting object model has been reduced to a thin ring. Results of calculation by using the developed models are presented for selected materials of tubular elements, which are commonly used for structures of the kind; moreover , they are prepared in a form of dimensionless diagrams, that makes it possible to use them for an arbitrary material.
