The introduction of an automated control system on the production line of the rubber compound will reduce the influence of the human factor on the quality of rubber products, which will lead to a significant improvement in the operational and physico-mechanical characteristics of the final product. Also, the development of this system will create a centralized data collection system for creating reports on technological operations of the production process. To obtain high-quality products, it is necessary to control and maintain all technological parameters during equipment operation at the same level, modern means of registration and parameter management. In the production of rubber compounds, it is necessary to ensure a high degree of automation of the main technological equipment, which will make it possible to more accurately dose the ingredients, including dusting ones, to conduct the process in a given temperature regime for the time required to obtain high-quality products. The implementation of automatic control during the use of high-performance equipment is not possible without the use of measuring and control equipment. The article is devoted to the problem of automation of a system for measuring technological parameters on a rubber compound production line in order to improve the quality of manufactured products. The analysis of the technological process is carried out, the controlled parameters of not only the modes of the technological process, but also of raw materials, semi-finished products and finished products are selected. The choice of instruments and local automation equipment is presented, as well as the choice of an industrial microcontroller with which control is carried out at the lower level of an integrated automation system. A functional diagram of the automation of the rubber compound production process is proposed, which will allow to obtain a product with quality indicators corresponding to the regulated level.

An increase of components production for the equipment intended for oil and gas production is a key factor for analyzing existing technological processes and searching for new technological solutions to improve the efficiency of the production process and the quality of components. The article presents a simulation model designed to determine the rational technological processing parameters for the production of the “Centralizer shell” part. The basis for optimizing the working cycle of a production line is synchronization based on the principle of proportionality, which involves equalizing the duration of all technological operations with the rhythm of the production line. Synchronization of technological operations on the production line is carried out by choosing rational cutting parameters for each technological transition (cutting speed, feedrate, number of working passes). The “Centralizer shell” part is made of titanium alloy VT16, which has high strength, corrosion resistance and ductility. For the part under consideration, the permissible values ​​of the cutting parameters were determined based on the calculation of the total processing error, as well as the frequency of replacement of the worn cutting tool. The simulation model described in the article made it possible to increase the efficiency of the production process due to the synchronization of technological operations and the search for rational technological parameters, as well as to improve the manufacturing quality of the “Centralizer shell” part by analyzing the processing error at various parameters of the technological process.

In this paper we consider the technological process of manufacturing micromechanical gyroscopes, the output of which is divided into cells of the crystal plate and each cell contains a fixed number of product elements. The estimation of structural similarity for measurements of technical characteristics of various devices is offered. A relatively large value of structural similarity assessment means that there is a dependence of the quality of the manufactured devices on the position on the crystal plate. This gives a good reason for further work to improve the quality of the process or to change the technological scheme as a whole. The article considers a numerical example based on a real sample of microelectronic products. The proposed method can be used both in the process of adjustment of the production process and in the rejection of products, when further configuration of the equipment is no longer possible.

The research objective is to improve the quality of soil loosening using combined working bodies for surface moisture-retaining soil cultivation. The efficiency of accumulation and conservation of precipitation in the autumn-winter period depends on the method of post-harvest soil cultivation. One of them is the autumn surface water-retaining treatment, which makes it possible to increase the efficiency of the processes of accumulation and conservation of moisture due to the deeper loosening of the cultivated soil layer. During loosening and mulching, the top layer of the soil contributes to the accumulation and preservation of moisture not only in the upper but also in deeper soil horizons. However, the used tillage tools do not fully solve the problem of the high-quality performance of surface moisture-retaining soil cultivation. The article presents the results of studies of the degree of influence of geometric and technological parameters of the additional active cultivator on the quality of surface tillage. Based on the results of the research carried out, the technological process of performing the surface tillage operation has been improved and combined working bodies have been developed for its implementation.

Fusarium oxysporum (F. oxysporum) is the pathogen that caused fusarium wilt diseases on the tomatoes. The rise of the symptom was caused by secondary metabolic produced by F. oxysporum. The associated with the level of secondary metabolic pathogenesis that cause symptoms of wilt on tomatoes, but secondary metabolic excreted by F. oxysporum was not necessarily wilt in a plant. The phenomenon caused F. oxysporum producing secondary metabolic in the different concentration, either its quantity or quality. The nature of physiology being tested, observed by growing 4 isolates using a medium PDA on the temperature of 10, 15, 20, 25, 30, and 35 °C. The content of secondary metabolic measured on the four isolates using the Notz et al., (2002) and analyzed by using High-Performance Liquid Chromatography (HPLC). The results of the analysis of the nature of the physiological (colour colonies) were that every isolate planted for 8 days shows the variation of white, white redness, white yellowness until purpleness. Based on Methuen Handbook of Colour (Kornerup & Wanscher, 1978), generally isolates tested shows a bright colour, signaled with A letter at every code. Analysis HPLC on the results of secondary metabolic, either quantity or quality, sequentially were: isolates BAR (3; 1,997 ppm); ENR (3; 5,105 ppm); SID (4; 2,135 ppm) and MAL (5; 2,065 rpm). If it was seen by the relationship between the colour of colonies with the production of the secondary metabolic compound, it seemed that the older or darker colonies’ colour the more secondary compounds formed, but dark or old colonies’ colour does not determine a high quality of acid fusaric produced.

Purpose – The importance of partnerships to organizational success has increased considerably the past decennia and many organizations strive at creating high-performance partnerships (HPPs). For this to happen, organizations in the partnerships have to be of high quality and their collaborations should be world-class. Whereas the factors that create high-performance organizations (HPO) are by now reasonably well established, the HPP factors are still unclear. The purpose of this paper is to develop a scale for measuring the factors of importance for creating and maintaining HPPs, and relates these factors to the factors of the HPO framework and to the success of the partnership. Design/methodology/approach – During a literature study ten potential factors of importance for creating and maintaining HPPs were identified. These potential factors were put in a questionnaire, together with the factors that create the HPO and the factor that measures the success of the partnership. This questionnaire was administered to a cable company, which was working on becoming an HPO, and four of its main suppliers. The data were subjected to a factor analysis which yielded a HPP framework consisting of three factors and 19 underlying characteristics. In addition, these HPP factors were put in a regression analysis with the factors of the HPO framework and the success of the partnership factor. Findings – The research results show a strong relationship between three HPP factors, the five HPO factors, and the success of a partnership factor. Research limitations/implications – This research adds to the literature by extending the concept of HPOs to the value chain these HPOs operate in. Thus the research into the factors of successful partnerships has been brought forward. The practical benefit of the research is that organizations can use the HPP factors to increase the quality of the partnerships they have with their suppliers and customers. Originality/value – There is much literature on partnerships but not so much on partnerships between organizations which strive to become a HPOs, and in the process need to create partnership of high quality.

It helps reduce pollution, and produce no sparks while burning, but varied due to different types of materials, burning protocols, temperature, and pressure used. In this study, the research team have studied the characteristics of high quality fuel briquettes for possible further development of standard indicators of briquette fuel production process. In the study, key factors of the Charcoal fuel features composed of high qualities of physical characteristics and electrical induction. Activated carbon and coconut shell charcoal types were showed to be great materials. The production process involved aerobic burning at 800-900oC for at least 3 hours, grinding and mixing with starch binder. The briquettes’ electrical conductivity was especially lower than 10 kΩ. High heat production was obtained at least 6000 Cal/g while ground charcoal possessed with the sizes were varied. Under microscopy, the charcoal particle sizes were in a range of 50-100 μm for 30-50% (w/w), size of 10-50 μm for 20-40% (w/w) and distinctive numbers of holes greater than 300 μ to 1 mm were rarely observed. Therefore, with key characteristics of charcoal briquette fuel, it could be further applied for development the indicator as well as instruments to measure the quality of the briquette.
