Abstract
The article presents results of experimental (using developed method and a tribometr) and natural tests of lubrications’ efficiency of various structures and decreasing wear’s friction. The authors give an assessment of influence of additives to plastic lubrication on the basis of graphite’s powders, disulfide of molybdenum and their compositions with additives (and an abrasive quantity) in the conditions of boundary friction at abrasive wear. The Litol-24 lubrication’s efficience is analyzed with modifiers in units of friction sliding of KAMAZ automobiles. It is shown that the other additives are inefficient.

Abstract
The article presents an algorithm of obtaining prognostic parameters of a dynamic object on the example of forecasting temperature of the internal combustion engine. The value of temperature predicted on the basis of Brown’s adaptive model is used for switching operating modes of the cooling fan. At exceeding admissible value of predicted temperature there is implemented a transition to an operating mode of the fan upon which there is a strengthening of turbulence of a heat carrier. The advanced control of the cooling fan of the internal combustion engine allows to increase the reliability of the engine.

Abstract
The authors, represented the University of Huddersfield in United Kingdom and Omsk financial university in Russia, investigate the problems of forecasting in small firms. On the basis of studying activity of Russian and English forms there are educed the barriers on the way of effective realization of a such important function of management as forecasting. It is proved that for small frims the Bayesian approach is the most acceptable for forecasting, the distinctive peculiarity of which is using, on the way with objective, subjective information, which may be obtained and systematized on the basis of subjective judgements of entrepreneurs who have a small business. As a practice shows, exactly subjective judgements play the significant role in making managerial decisions in small business.
