THE RESEARCH OF PARAMETERS OF WOODEN CHIP COLORING
DescriptionThis work presents main kinds of colourants and methods of painting wood particles. Based on wood structure analysis, it was revealed that hard wood, possessing tracheides and vessels as conducting elements, have the optimal capacity for coloration, in comparison with coniferous trees. A methodology was developed of cloning wooden particles, in the form of chips, with forced immersion in order to obtain established parameters of saturation and brightness. The experiments were conducted with chips of 15-50 mm long, 5-20 mm wide and 3-7 mm thick. The composition of colouring agent included water, acetic acid, and water-emulsion colourants of different types and colours (№1 – colour code (red, yellow, and brown) №2 – colorant (lilac and orange) and №3 – paint). Experience has shown the needed concentration of liquors and mass percentage of compounding ingredients. The research was undertaken to study concentration dependence on the time of allowance and saturation. In consequence of colouring experimental batches of chips, a painting saturation of 4-9 points was obtained at the allowance of 120 and 140 seconds. Dependence of brightness from solubility was determined, with high correlation between given parameters on Pearson Criteria (more than 0.9). Comparative analysis made it possible to discover that the better colouring of particles is created with the red paint. In this case maximum colouring effect is achieved with liquor of water-emulsion paint. Subsequent to the experimental results, a design of installation for colouring wooden particles was developed and patented

Description
The object of the article is to consider the surrounding factors of city passenger motor transport of the municipal union «City of Magadan» and to estimate the degree of their influence to municipal transport infrastructure by means of the PEST-analysis, SWOT-analysis, a method of pair linear correlation, and a method of profile city surroundings. As a result of this analysis, the basic directions of the strategy of city passenger motor transport development are defined, some recommendations improvement of management efficiency by public transport from the institutions of local government are made

INSTITUTIONAL INFRASTRUCTURE: ESSENCE AND CONTENT
DescriptionThe article discusses the concept of "institutional infrastructure" and clarifies its essential content in relation to market cars. In terms of the industry market the main purpose of the institutional infrastructure is achieving the maximum economic benefit within limited resources. The main tasks that need to be solved in order to achieve this goal were formulated. We have developed and proved structurally-logical chart of the elements of the institutional infrastructure. The content of the institutional infrastructure of the car are presented and justified. The analysis condition of the car market’s institutional infrastructure showed the problems associated with the state of institutions which have an impact on the functioning of the car market. Measures to stimulate the car market does not cover entire sector as a whole, and imported institutions do not give the expected effect because of inconsistency formal and informal elements of the institutional infrastructure. Presented assessment of the institutional infrastructure of the car market confirms the dependence of the state of the industry market cars from institutional infrastructure. Only reforming the institutions at all levels of the industry, from production to car sales can have a positive effect on the industry. Changes in the institutional infrastructure should be focused on improving the competitiveness, stability and independence from external factors

INERTIAL METHOD OF CHAIN TRANSMISSION QUALITY CONTROL
DescriptionThe article suggests science-based and experimentally tested method of chain transmission quality control. This method enables to estimate the losses due to friction in the transmission chain that directly affect the efficiency of the chain drive. The method can be used both in the chain production stage, as well as in the operation, maintenance, and repair of a chain drive
