    The article characterises the properties of steam and special thermal oils as the basic heating media on motor ships. The features of the heating installations have been presented with the particular attention drawn to thermal oil installations in which exhaust gas heaters have been employed. Also an example of the comparative exergetic analysis has been included demonstrating the comparison between steam generation in exhaust gas boiler and oil heating system in the heater, assuming the identical heat flux transferred in the boiler and the heater from the exhaust gas to the heating medium (steam and thermal oil) and assuming identical increase of exhaust gas entropy in the heat exchangers under examination

    This article focuses on the sources of conflicts between a traffic maintenance department and production department which are very often unidentified by managers of an organization. These conflicts lead to the reduction of affectivity of an enterprise thus, the authors of this article tried to indicate all causes which result in an inappropriate cooperation between them. The identification of these problems and their analysis will let the organization take actions, which will improve the cooperation between two closely cooperating departments which, in turn will result in bigger effectiveness. The analysis of the problem was conducted in one of production company in Silesia voivodeship

    This article is a trial to describe an author’s research method of measurement of an inside client’s satisfaction where in an enterprise, a inside client is production departments whose satisfaction with traffic maintenance staffs is to be assessed This method is based on a questionnaire survey which is conducted by means of two specialty prepared questionnaires. The first questionnaire refers to a production department’s satisfaction with actions taken by traffic maintenance staff and the second allows to assess the abilities of realizing tasks by traffic maintenance department in an organization. The obtained results, after analysing, allow to point out areas where repair actions should be taken or actions which are to improve the cooperation between analysed departments. This method is still at the stage of testing

    The paper is characterized by efforts to create a business model of enterprise software and technical documentation. The author points out that the overriding factor is to identify actions to modeling, which defines the scope of the project. In mapping the organization and construction of scenarios of business processes is of paramount importance dictionary of phrases and descriptions of domain rules of correctness for the recording and processing. The author describes the key process models, partial (procedures) and elementary (the workflow map.) This indicates the suitability of BPMN and UML notation in the record of the mapping rules and modalities for the functioning of the organization and in the description of static and dynamic structure of the system. Pointing to the integration of business process management system architecture author assesses the suitability of the chosen modeling notation

    In this paper, we examine sources of optical radiation and the effects of interaction of specific types of optical radiation i.e. ultra-violet, visible and infra-red, on a human organism. Next, the current criteria for assessing optical radiation hazards and contemporary measurement methods for establishing the total and effective intensity of irradiation with ultra-violet radiation, as well as the intensity of irradiation with infra-red and visible radiation. In the following section, examples of temporary working posts for welders were presented, as used during maintenance works aboard ships. Measurement results for optical radiation at the selected working post were then quoted, accounting for three specific exposure times. The last section contains conclusions drawn from measurement results and interviews with a group of ship hull welders

    The internal fixation of maxillofacial fractures with plates and distracters has gained growing popularity during the last decades. The design of implants for fracture fixation has undergone a gradual evolution over the years as researchers have tried to facilitate healing and decrease the rate of complications. Osteolysis is one of the foremost problems limiting the survival of current implantation procedures. It is induced by the wear particles and corrosion products which incite an inflammatory response resulting in bone resorption and eventual loosening and failure of the bone fixation. The future research will help to limit the effects of wear particles by identifying the most suitable bearing surfaces. The pathologic cascade of events triggered by wear particles may be a potential site of action for drugs intended to prevent or check the progression of the disease. The paper presents a damages problems of the maxillofacial plate fixation. The surface failure at plate stabiliser elements showed typical damages for this system. Damages of screw’s steepl heads as well as the surface layers failure of the the coned seat on tie plates were observed. The surface failure at a screws were visible in a lesser degree. The biggest wear areas are visible on the cooperating surfaces of the plate sockets and the bone screw heads. Many types of damage characteristic of processes of corrosion damage and tribological wear, mainly abrasive, adhesive, and fretting wear, are observed here

    The EPC methodology enables accurate modelling of economic processes. One of the main spheres of its application is procedure creation under quality, occupational health and safety or environment management systems. The development of the methodology in question has led to establishment of precise conditions that must be conformed with in a correct process model. The main theme of the article is a general discussion of the EPC methodology. Based on an analysis of numerous literary studies published, a set of principles that should be met by an EPC diagram as a graphical representation of the process being described has been identified and discussed. Another subject touched upon in the article is the results of examinations of 156 diagrams from documents of integrated management systems implemented in two companies. The examinations conducted have implied that the diagrams created in the course of the documentation drawing up do not conform with many of the applicable requirements. The individual syntax errors occurring in the documents have been identified and discussed in the paper, and special attention has been paid to those related to application of the OR and XOR split connectors as well as those occurring when joining diagrams
