Sergei Mikhailovich Eisenstein is not only a great filmmaker but also one of the first theorists of cinema, whose ideas have not lost their significance to this day. Exploration of Eisensteins theoretical heritage reveals the relevance of many of his propositions based both on the practical experience of the director and on his theoretical conclusions and even insights.Such ideas include, in particular, the concept of audiovisual counterpoint introduced by Eisenstein in the famous manifesto Budushchee zvukovoi fil'my. Zaiavka (Statement on Sound) of 1928. In this manifesto, a number of provisions expressed the authors' concern about the possible non-cinematic use of sound in films, and at the same time, the future possibilities of sound in cinema. In particular, it was argued that only the counter-punctual use of sound in relation to the visual editing piece gives new opportunities for montage development and improvement. Subsequently, Eisenstein clarified or even revised some of the points put forward in 1928. With the experience gained in the sound field of filmmaking and the logical development of theoretical research, the idea of audiovisual counterpoint as a cinematic method grows into the problem of artistic imagery, and the contrasting of image and sound becomes part of the task of creating polyphonic (polysemantic) audiovisual solutions in a motion picture. The essay discusses the relevance of Eisenstein's ideas within contemporary artistic and theoretical contexts.

Like in many other provinces, during the Habsburg period, the main point of orientation for Galicia was Vienna. This also applies to architecture and urban development. Galicia’s technical elite applied the theoretical and practical experience it gathered in Vienna to the towns and cities of this northeastern Crown land. Ignacy Drexler, born in 1878 in the Austro-Hungarian Lemberg, was a representative of a new generation of engineers and architects who did not necessarily have to spend time in the imperial capital to earn their spurs. Increasingly, besides the more or less obligatory stay in Vienna, other European countries became points of reference. Drexler did not live to see the realization of important aspects of his comprehensive plan for the city, but his ideas and the data he compiled were indispensable for the future development of his hometown. They shape urban planning in Lviv to this day.

Negative Effect

Many students appear to be continually connected to social media sites such as Facebook. Such social media sites can be pervasive in nature. The use of these sites through mobile devices often extends into the classroom, sometimes to the detriment of scheduled teaching activities. Further, many students do not seem to be aware of the negative effect that ill-considered information placed on social media sites can have towards their future employment. This chapter reviews the positives and negatives of social media as it relates to the future employability of students. Due to the changing nature of this field, the chapter is largely presented from practical experience, rather than a traditional academic research-led approach. Much of the focus is on the ways that students can present themselves online in a manner which should encourage employers to offer students jobs and placement opportunities. The chapter reviews a number of the major Websites where students should establish professional profiles. It also looks at the overall need for students to establish a professional presence online and show that they are a desirable employee. The chapter concludes by looking at the challenges involved with integrating the teaching of employability through social media into existing teaching. A number of research areas for further consideration are also presented.

Relationship Of

In the introduction to this chapter, we discuss some of the common problems in maintenance. In order to solve these problems, we find it necessary to think in a new way, including the relationship of businesses to the system maintenance. The world outside organisations changes continuously, and the business processes and functions must change with it. However, if we only maintain information technology (IT) and do not co-manage the business changes accordingly, IT will not change at the same pace as the business changes. It would result a gap between the business needs and services provided by the IT product. In that case, IT systems would not be able to provide sufficient business value. The main part of this chapter contains a management model for solving these problems, based on theoretical research and practical experience. The central theme of the model is the connection between the business needs and systems maintenance. This is achieved by maintaining maintenance objects rather than the systems, establishing micro-organisations for each maintenance object where business processes as well as the system are represented. Our proposed model is widely used in more than 50 organisations in Sweden. In conclusion, some future trends and central concepts of the model are discussed.

Hydraulic Cylinders

In mechanical engineering, there is a trend to use new materials which are an alternative to metals. This also applies to construction components and hydraulic systems, where more and more attempts are made to use plastics as construction material. This solution brings design, technological and economic benefits. The researchers from the Fluid Power Research Group of the Department of the Fundamentals of Machine Design and Tribology from Wroclaw University of Technology (www.fprg.pwr.wroc.pl), are working in this area, with an objective to create a complete hydraulic system whose basic elements such as the pump, valve and actuator are, entirely or in their substantial part, made of plastics. The paper presents the course and outcome of the design process and the research, the aim of which was to prepare a demonstration model of the hydraulic cylinder made of plastics. The work on the model of the actuator started from an analysis of traditional methods of designing hydraulic cylinders made of metal. The authors analyzed the course of the design process, paying particular attention to aspects of the strength of the actuators’ structure. It highlights the main elements and the important nodes occurring in the hydraulic cylinders, namely the sleeve, the bottom, the head, the piston, the piston rod, the fasteners, the hydraulic fluid ducts, the sealing, and the bolts. An algorithm for the procedure in a form of a block diagram was presented, and the necessary calculations were made. Taking the characteristics of the actuator and its respective nodes into consideration, it was found that a number of metal parts may be replaced by plastics. The result of the operations performed is the proposal of a model of the actuator elements made of plastics. For this solution, a 3D computer model was prepared and studied by means of the FEM. The obtained results allowed the identification of the place, the nature and the value of deformation. Based on the results of the theoretical research, it was found that the structure of the actuator will not be effected in the course of its work in the assumed conditions. A demonstration model of the actuator was created according to initial assumptions. The next step was to prepare and conduct preliminary studies on the actual model. The first tests were carried out with no load being applied. The tests were made with different speeds of the piston rod’s movement and the operation of the actuator was observed. Next, tests of the loaded actuator model were conducted. For that purpose, it was put on a special stand with a metal actuator in such a way that a linear displacement of the two rods along a common axis was provided. In that system, the conventional actuator enabled the loading of the model’s piston rod. Tests were carried out at different values of pressure and speed within the full motion range. Based on the prototype’s volumetric efficiency measurement results, the operation of the tested actuator featuring the elements made of plastic was proved correct. The theoretical and experimental research on the hydraulic actuator confirm the possibility of applying plastics as a construction material in devices of that type. The use of the actuators’ design algorithm showed that it can provide a theoretical basis for the design method of the actuators made of plastics. The algorithm, however, requires modifications taking into account the special properties of plastics due to their anisotropic nature. The development of a definitive method is planned in the context of further research. Additionally, the future development of a design solution for a cylinder of smaller dimensions, which could provide an alternative to traditional low-pressure actuators or pneumatic actuators. The future research direction is the analysis of the processes taking place in the individual parts of the plastic cylinders. A challenge of some kind may be to select sealing’s that will ensure long and trouble-free operation of the actuators.
