Purpose. To develop the method for increasing the efficiency of the equipment’s maintenance and repair system, ensuring necessary level of operational reliability of the equipment, safety and reliability of the electric equipment with minimal expenses on operation. Relevance. Aging of the power equipment in railway power supply systems sharply raised a need for assessment of its states and degree of risk for operation outside rated service life. In critical conditions of technological processes and operational modes of the railways it is necessary to increase the equipment’s operational reliability. The scheduled maintenance and repair system whose main technical and economic criterion is the minimum of equipment’s downtimes on the basis of a rigid regulation of repair cycles, in the conditions of market regulations in the field of repair in many cases does not provide the optimal decisions due to insufficient financing. The solution of this problem is possible by improvement of the maintenance and repair system. Under these conditions the main direction for supporting the operational reliability of power electric equipment on TS is a development of the modern methods based on individual supervision over real changes of technical condition of power equipment. Scientific novelty. In this article the authors proposed an integrated approach, on the basis of which can be developed the effective maintenance and repair system for traction power supply systems. Proposed approach allowed to react quickly to changes of service conditions on traction substations, to control the technical condition of power electric equipment under the conditions of uncertainty, to establish interrelation between quality of service and operational reliability of the equipment, to choose a service strategy on traction substations. Practical importance. The validity of the developed method was confirmed by the results of calculations and practically by choosing the optimal maintenance's option for transformer TDTN-25000/150-70 U1 (ТДТН-25000/150-70 У1) on traction power supply substation.

Summary Among many different definitions of competitiveness it is difficult to pinpoint the most appropriate one. In the paper it was defined as the ability to be profitable by effective use of available resources. The profitability ratios (ROS, ROA, ROE and value index) were proposed as measures of competitiveness and resources were indicated as one of the group of factors that has an impact on it. Precisely, the purpose of the paper was to examine the relationship between selected resourced based factors and competitiveness of agricultural enterprises. The study was done with the use of correlation analysis on the basis of statistical data on selected Polish companies operating in agriculture. The main finding was that the analyzed resources (the level of labour, size and quality of agricultural land and size of assets) were weakly correlated with competitiveness. This observation means that other factors have stronger impact on agricultural company’s competitiveness. They can refer to intangible resources (such as relational capital, know-how, managerial competencies, technological resources etc.) and external conditions (such as climate, legal issues) of agricultural enterprises.

A 2009 Volkswagen Jetta was tested using a Portable Emissions Measurement System (PEMS) SemtechD emissions analyzer to determine when the emissions and fuel consumption will be the smallest in regards to startup vs. idle emissions. An idle time equivalent was calculated to determine when idle emissions became equal to startup emissions at four different ambient temperatures for a cold start. The mass of Total Hydrocarbons (THC) emitted limited the idle time equivalent to less than the startup time for all ambient temperatures. The temperature of the Catalytic Converter (CC) was monitored to determine how quickly the car cools down and therefore, how beneficial it is to turn the car off after a certain time period. For the temperature range tested, it was more beneficial for reduced emissions to turn off the car compared to idling by a factor of at least four. The data suggests a trend that idling would never be the best option; however, more testing needs to be done with a greater range of CC cool down temperatures to confirm this initial assessment.

The Impact

Purpose – The purpose of this paper is to explore the relationships between the openness of firms and their innovation and financial performances. Design/methodology/approach – In order to investigate such relationships, data on inbound and outbound open innovation (OI) processes and performances of 110 worldwide top research and development (R & D) spending bio-pharmaceutical companies are collected via the consolidated annual reports and the PATSTAT database. The time period of the analysis is 2008-2012. Findings – Regarding innovation performances, R & D productivity and revenues to patents ratio decrease with openness, whilst patents growth is not influenced by OI adoption. As to financial performances, sales growth exhibits a positive trend with openness, while operating profit and turnover decrease with OI adoption. Particularly, an inverted U-relationship with inbound and a U-shape one with outbound are observed as of operating profit. Research limitations/implications – The study adds to the knowledge about the effect of openness on firms’ performances, a topic of increasing interest to academics, managers and policy makers. Both inbound and outbound facets of the phenomenon are taken into account. Practical implications – Understanding how openness affects performances enables more informed decision making by managers, leading to a more effective use of OI activities. Originality/value – The work provides new insights as to what “being open” means for a company, gauging both inbound and outbound transactions after a pecuniary perspective. Employing objective and continuous measures, the relevance of OI for the whole business of firms can be identified.

The article deals with the problems of increasing the economic efficiency of agricultural enterprises by improving working conditions, reducing the level of exposure to harmful and dangerous production factors. The purpose of the article is to analyze methodological approaches to forecasting possible economic losses of agricultural enterprises due to the presence of harmful or dangerous working conditions and to develop organizational and management solutions to reduce these losses. Economic services of agricultural enterprises need to have a methodology for assessing real economic losses due to unfavorable working conditions at enterprises, which will give employers an understanding that the costs of labor protection and safety not only pay off, but also give a significant economic effect and contribute to improving the profitability of production and allow them to make informed management decisions. It is shown that forecasting economic damage from occupational diseases and industrial injuries, accidents is a complex task, but it is quite solvable on the basis of the procedure for assessing and managing occupational risks and applying known patterns of crop losses or animal productivity due to violations of agrotechnical deadlines or animal maintenance regime due to the absence of an injured employee at the workplace.

Abstract In the modern world a person strives for an industrial society more and more, accumulating power and trying to enclose them in one machine that would perform several operations in one pass over the field surface. So there are implements performing tillage with application of fertilizers or soil cultivation with simultaneous planting and application of fertilizers. Using such implements allows to reduce costs for further cultivation of crops. However, the stake placed on soil preparation and application of fertilizers can not always give the desired effect without due attention to the seed material and technical maintenance. That is why seedbed preparation, the seed material and machines are the main problems of high technology society.
