The article is devoted to A.R. Esayan, the founder of the Chair of Informatics at Tula Pedagogical Institute. The paper examines the influence of Professor A.R. Esayan's methodological legacy on the training of modern IT teacher. The article reveals some aspects of his influence on the "Computational methods" course: the development of students' algorithmic culture; the study of CMS capabilities; the use of recursive algorithms in problem solving.

This paper underlines the dialogue oratory performances of the tour guide. The dialogue form of verbal statements is the main job of the tour guide, to present information in front of the tourists through a tour guiding talk on the visited tourist site. One of the most used methods during dialogue oratory performances of the tour guide are: talk, polemics, discussion, argument, dispute, debate, consultation, which deserve special attention regarding their didactic advantages and disadvantages. Having in mind the specific nature of the tour guide service, provided by the tour guide to the tourists, the presence of dialogue oratory performances requires a better theoretical understanding of them, in order to better apply them in the tour guiding practice.

The present study considered the possibility to use low octane component as an additive at production of commodity gasoline. The new restriction norm for quality of fossil fuel are required limiting of some unlikely components as benzene and sulfur in gasolines. The obtained fuels might not good phisic-chemical characteristics for a commodities products and must adding several packets of additives. In this paper is used a low octane component as an additive for improving a gasoline fraction to commodities gasoline. [ABSTRACT FROM AUTHOR]

Here are presented some software programs for data acquisition, processing, filtering and graphical displaying of data from the three dimensional accelerometer. This paper provides a basis for a more complex system, the purpose of which will be a transfer of the outlines of the spatial objects in 3D computer graphics, using a combination of linear and angular acceleration sensors.

In the paper the associative analysis as a Data Mining technique is investigated. The properties of the algorithms for extracting the associative rules is analyzed and compared. The associative analysis is used for discovering and exploring hidden and interesting relationships between items in large amounts of data. The extracted patterns are presented in the form of association rules or sets of frequent items. The associative rules are represent in the form IF A then B. For studying of various algorithms is used open source software RapidMiner. [ABSTRACT FROM AUTHOR]

This paper presents a modeling of the total solar radiation by a simplified formula on warming with reporting of energy flows. Energy research has been carried out to change the temperature in a closed cube insulated and blackened inside. It is assumed that the energy input (from Sun or light source and immediate surroundings) is constant. The change of the energy is greater than zero, because we have heating. The increase in the energy at any point is proportional to the difference between the maximum power and energy in the interior of the cube, as well as the interval time, which is a basic assumption in the theoretical model in the first approximation. The formula allows calculating the change in energy in the present model. The new method provides possibility to calculate the hourly daily total solar radiation at certain location. Such information would be useful for designing various radiation -- utilizing systems (solar power plants, greenhouses, etc.). Research and study results of this kind are important for the sciences and technologies of our modern world at a time when solar energy as an alternative energy is of utmost importance for the preservation of the natural energy resources of the planet Earth.

Data on the standard enthalpy of formation of tellurites of rare earth elements are scarce and this determined the interest towards these studies. The present paper reports for studies and suggests four methods for calculation of the standard enthalpy of formation on the rare earths tellurites synthesized. An assessment of their accuracy was performed and the relative error rates in the general practice of the of Gauss least squares laboratory method were found. The dependence DSC of the molecular masses of the tellurites synthesized was investigated and graphically represented. To calculate the standard values of the enthalpy of formation of the lantanides' tellurites studied, the Newton's interpolation formulae from the mathematical calculation methods were used for non-equally spaced argument values, applied for analysis and prediction of the standard enthalpy of formation.

The transport of crude oil and petroleum products by oil and gas pipelines is more economical effective than other types of transport. They also help to accelerate supply of oil refinery with the necessary raw materials for the smooth transportation of oil from the field to the nearest port or petroleum bases. This paper deals with some environmental problems associated with transportation of oil and petroleum products by pipeline worldwide and assesses the oil spills. [ABSTRACT FROM AUTHOR]
