Dmitriev-Mamonov is primarily known for his story that describes inhabitants of other planets. The story contains some controversial elements including an unflattering image of the clergy, heliocentrism, and the possibility of multiplicity of worlds. He also authored a Chronology and a free translation of part of the Psalter in which he included some of his theological views.

“Mineral deposit model”, “deposit modelling” are the terms commonly used, although imprecise. This is often identified as the application of computerized methods to the elaboration and presentation of geological information, in particular for the mining design. Deposit modelling is the mode of presentation of deposit features, which in the meaning of the authors of such presentation, describes the deposit features between the points of observations as best as possible. Deposit modelling has a long history (XVI-XVII centuries), however such a term was not used. Varied methods of cartographic presentation of deposits and their features were proposed. The progress in the presentation of the deposit in space using isolines maps has led to the separation of methods of deposits geometrisation. Over time, a simple mathematical statistics method was used to describe the deposit parameters, followed by geostatistical methods. Some of them were however not commonly used as too troublesome. The computer based approach to the presentation of geological data has an unquestionable value but is accompanied by the possibility of inappropriate formalized and erroneous interpretations and a presentation as to whether the basic rules of geological knowledge were neglected. Deposits modeling is a conceptual task and cannot be fully automated.

Presented article contain the teachers opinions of the perceived social expectations in relation to their own expectations of both the institutions of school and local educational authorities. The starting point is a thesis that asymmetrical and disproportionate expectations conducive to the construction of the reduced school reality a specified group of students. as reality shows school does not always reflect the social expectations, which is closely connected with the attitudes of teachers in mainstream schools. however, their expectations of working conditions and the same students with disabilities often remain inconsistent. To identify and interpret the reality that create the appearance of the school, the topic is examined in the context of the concept of the reduced space and the theory of games.

The paper presents a concept of an active filter with energy storage. This solution can be used for the compensation of momentary one phase high power loads with discontinued power consumption (e.g. spot welding machines). Apart from the typical filtering capabilities, the system’s task is also the continuity of the input power from the feeder line and limiting its fluctuation. The proposed by the author’s solution can produce measurable economic benefits by reducing the rated power necessary to energize periodically operating loads and improving the indicators of electrical energy quality. The developed method of active power surges compensation enables a flexible approach to requirements concerning the rated power of the point to which the periodically operating loads with high peak current value are connected. The tests were conducted on a simulation model specially developed in Matlab & Simulink environment, proving high effectiveness of the presented solution.
