Existing processes of cleaning emulsion sewage are based on either physicochemical technology with application of complex of reagents – nonorganic electrolytes and organic flocculants, resulting in obtaining highly-mineralized purified water, which cannot be used for technical water supply, or based on complicated technologies of electrocoagulation and ultrafiltration. This required elaboration of a new technology and equipment for cleaning concentrated emulsion sewage, in particular, those containing emulsol of Wedolit EP-5 grade, used for hydro-mechanical expanders of electric-weld pipe lines. The technology stipulates a successive introduction of a reagent – suspension of alumo-silicate based hard-phased sorbent and solution of flocculant of cation type Praestol-650ВС – into emulsion sewage, their mixing with emulsion water in a definite mode, sedimental differentiation of the formed phases in a precipitator-flocculator “ЭП ОФ”, gravitation concentration and dewatering of the obtained sediment at vacuumfilter. The dewatered sediment can be utilized in cement industry and metallurgy. It was shown that application of the hard-phase sorbent does not result in an increase of mineralization of purified water and enables to use it for technical purposes. The group of companies “ECO-PROJECT”, Ekaterinburg, accomplished a project for Chelyabinsk pipe-rolling plant, elaboration and manufacturing of equipment, as well as commissioning and start-up of the equipment. The elaborated technical solutions in the process of equipment running showed a high efficiency and can be used as a base for creation of facilities of any productivity for cleaning multi-type emulsion sewage at enterprises of various industries.

Maintenance management is connected with two opposing aspects, management costs and operational efficiency. With the implementation of new technology within the Industry 4.0 (I4.0) concept, new technical solutions are being created. These solutions (mainly robotic workplaces) must reach a maximum performance rate, production quality, and, of course, high availability. Their operation, during the whole life cycle, is expected to be absolutely safe with minimum maintenance costs. These trends, even though they seem to be optimistic, face a lot of problems. The conducted research follows up on the results of previous research aimed at the initial assessment Slovak industrial company readiness status for the I4.0 conception between 2017 and 2019. The aim of the ongoing research was to assess the readiness status in more than 70 industrial organizations in the selected area for the new concept of maintenance management (eMaintenance) and its relation to machinery integrated safety. The research was carried out by questioning, with the structure of individual questions and closed answers stemmed from the self-evaluation according to the new European Foundation for Quality Management (EFQM) Excellence Model (2020). The results of the research were presented to managements of questioned organizations and confirmed the assumptions about a low level of maintenance management transformation to eMaintenance.

The Impact

Purpose – This paper seeks to advance ongoing research in entrepreneurial perseverance. While the concept of perseverance is not new, few researchers paid attention to behavioural persistence in the entrepreneurial context. The purpose of this paper is to explore the emergence of new technology based firms (NTBF) by focusing on the role of nascent entrepreneurs’ social skills in the meeting the changes of entrepreneurial perseverance. Design/methodology/approach – In this paper the authors study the start-up phase of entrepreneurial process. The authors opted for a longitudinal case study approach in order to enhance the knowledge on entrepreneurs’ social skills and perseverance. For triangulation purpose the data were gathered using four different information sources. The use of Nvivo8 as the data analysis tool helped to impose a discipline and structure which facilitated the extraction of core insights. Findings – This paper contributes to the understanding of the entrepreneurial perseverance in the context of new venture creation. Particularly, reading the entrepreneurial process through the lens of the perseverance strategies model (Van Gelderen, 2012) provided a way to identify and then to assess the impact of the social skills on the overall entrepreneurial perseverance and their combined impact on the performance of NTBF creation process. In doing so, the authors identify the impact of entrepreneurs’ social skills to deal with a series of entrepreneurial problems such as scarcity of resources, uncertainty and ambiguity and consequently their impact on the likelihood of survival for new ventures. The issues that arose mostly reflected the inherent complexity of technology transfer processes, the university and entrepreneurs’ diverging cultures, and the very characteristics of the start-up phase of NTBFs. The findings reveal how social skills impact the entrepreneurial paths and probable outcomes. Research limitations/implications – This paper contributes to the understanding of the entrepreneurial perseverance in the context of NTBF creation. The findings reveal how social skills and perseverance impact the entrepreneurial paths and probable outcomes. Practical implications – The paper has implications for entrepreneurial support mechanisms such as technology business incubators in helping them to improve the efficacy and efficiency of their assistance to entrepreneurs through the development of their skill-sets and perseverance and providing enabling networking. In addition, the research has implications for entrepreneurship education and training. Indeed, there is an urgent need to design and implement courses and programs aiming at developing soft skills in entrepreneurship. Originality/value – In exploring networking and issues of perseverance for nascent entrepreneurs operating in new technology-based sectors, which the authors consider as an under searched area in entrepreneurial literature.

High Energy Consumption

In cement industry, many grinding up systems are on operating now. The tradition process of tube mill grinding system is high energy consumption, so it’s low efficiency, especially in the final cement grinding process. The value and advantage of slag is recognized more and more, but it’s difficult to be grinded up. Furthermore, the disadvantage and shortages to grind up clinker compounded with slag to produce cement are obvious and adopted. The best process is to grind up slag, clinker separately. Then, these two kinds of powder are compounded by a mixer. Hereby, it introduces a design of the process to grind up clinker, slag by one roller mill.

It is becoming increasingly important to understand the mechanism of regulatory elements on target genes in long-range genomic distance. 3C (chromosome conformation capture) and its derived methods are now widely applied to investigate three-dimensional (3D) genome organizations and gene regulation. Digestion-ligation-only Hi-C (DLO Hi-C) is a new technology with high efficiency and cost-effectiveness for whole-genome chromosome conformation capture. Here, we introduce the DLO Hi-C tool, a flexible and versatile pipeline for processing DLO Hi-C data from raw sequencing reads to normalized contact maps and for providing quality controls for different steps. It includes more efficient iterative mapping and linker filtering. We applied the DLO Hi-C tool to different DLO Hi-C datasets and demonstrated its ability in processing large data with multithreading. The DLO Hi-C tool is suitable for processing DLO Hi-C and in situ DLO Hi-C datasets. It is convenient and efficient for DLO Hi-C data processing.

This paper presents a novel process comprising solar upgrading of hydrocarbons by steam reforming in solar specific receiver-reactors and utilizing the upgraded, hydrogen-rich fuel in high efficiency conversion systems, such as gas turbines or fuel cells. In comparison to conventionally heated processes about 30% of fuel can be saved with respect to the same specific output. Such processes can be used in small scale as a stand-alone system for off-grid markets as well as in large scale to be operated in connection with conventional combined-cycle plants. The complete reforming process will be demonstrated in the SOLASYS project, supported by the European Commission in the JOULE/THERMIE framework. The project has been started in June 1998. The SOLASYS plant is designed for 300 kWel output, it consists of the solar field, the solar reformer and a gas turbine, adjusted to operate with the reformed gas. The SOLASYS plant will be operated at the experimental solar test facility of the Weizmann Institute of Science in Israel. Start-up of the pilot plant is scheduled in April 2001. The midterm goal is to replace fossil fuels by renewable or non-conventional feedstock in order to increase the share of renewable energy and to establish processes with only minor or no CO2 emission. Examples might be upgrading of bio-gas from municipal solid waste as well as upgrading of weak gas resources.

Transfer Capability

Knowledge transfer (KT) activity at a research performing organization (RPO) is usually reported as a set of metrics arising from the RPO’s research and engagement, such as links to industry, intellectual property creation, licensing of new technology and new start-up company creation. However, these basic metric sets are not very effective, either from the point of view of benchmarking or as measures of quality. To address this inadequacy, the author has developed and implemented a ‘knowledge transfer capability maturity framework’, which attempts to capture the essentials of good-quality management across key KT processes, providing for the identification of deficiencies and subsequent improvements. This article also presents the use of the ratios of currently reported metrics as an additional and helpful benchmarking tool, and the possible use of these ratios as a means of quantifying the quality measurement of the capability maturity framework presented.

The recuperation by means of external waste heat sources, as opposed to the recuperation of the turbine exhaust gases (to preheat the compressed air), allows one to utilize the hot exhaust gases of the gas turbine in the bottoming steam cycle to produce steam in order to generate additional power. Such a combined gas/steam energy system, closely integrated with the industrial process, can produce electric power (and useful heat) with high efficiency and very low atmospheric air pollution. In the present paper two examples of applications of this new technology have been analyzed from the economic and ecological viewpoint.
