Open knowledge and education at the new level of web paradigm
No full textAs www, and now web 2.0 is growing by the second, it gives us new possibilities of pedagogical forms, and the main following outcomes: resources, implementation, usage, practice. We will re-evaluate and examine new forms of social networking - theoretical and practical knowledge in academia and science: from implemetation of web roots practice, listservs, eBoards, eZines (alternative art and education forms –then), the usage of eResources in academia, education profession to the wider audience: using larger online open archives, Consortias, digital libraries, repositories, to online social networking applications, science and education blogs.
Author uses and presents data from her Master research paper with relevant results about the usage of the precious online resources, electronic publishing materials within Consortia (that are available in science institutions, academia and libraries). More than thousands and thousands available resources are not used because of many factors that the author explained in one of the chapters in master paper. As indicated in outlines, e-tensions play themselves differently in various institutional geographies. Author took empirical research on three geographic points: USA, Europe (UK and Nederlands) and Serbia.
The Scopes are two paradigms: human factor and digital media educational tools (human-computer interaction and its social impacts), that we use in education systems and professional practice. For the first one is indicated open source educational software, applications and tools for giving information and knowledge. We will also give a short notice on the interest and the usage of the aimed groups of those possiblities (at classes, lectures). For the second, in professional practice we will see how those social knowledge tools have impact on larger science commnity groups (science, educational institutes and institutions) as well as the outcome-feedback.
The point will be given on interaction in open knowledge and education, as well as the notice to the audience of the recent exemplar of implementation of social, interactive knowledge into professional practice and educational system - the concept of web of science which founder is the father of World Wide Web Tim Berners- Lee
The rationale for a wider concept of Inclusive Education for teacher education: A case-study of Serbia
No full textTeacher education for inclusive education (IE) is recognized as vital for improving quality and equity in education globally. In the Western Balkan countries it is also part of the transition process towards joining the European Union and has attracted international funding for IE-related projects. A key finding from research funded by the European Training Foundation, carried out by the authors as members of a seven-country research team in 2009-2010, was that the prevailing local understanding of IE was very narrow. In this article we hypothesize the reasons for this finding. We use a case study of school and teacher education systems in Serbia to explore how this understanding has constrained the development of IE and associated teacher education and limited the efficacy of some recent internationally supported developments. We identify both challenges and possible ways forward for teacher education for IE based on promoting a concept of IE that is both collaboratively agreed and comprehensive. © 2012 UNESCO IBE
916-85 Correction of Mitral and Tricuspid Regurgitation Improves Hemodynamic and Clinical Status in the Patients with Primary Dilated Cardiomyopathy
No full textPatients with primary dilated cardiomyopathy particularly at the terminal stage represent a special clinical problem because of refractoriness to medical treatment. The influence of mitral and tricuspid regurgitation to the hemodynamic parameters is very important. In our institution the correction of mitral and tricuspid insufficiency was performed in 24 patients (5 females and 19 males) with the mean age of 48 years. Reconstruction of the mitral annulus was carried out by the application of Carpentier's ring and by the method of Prof. Radovanovic in 9 and 15 patients, respectively.The analysis of hemodynamic parameters was made in the period prior to the surgical intervention (cardiac catheterization, before ECC) and after the correction (after ECC. 24 and 48 hours from ECC). The results are presented in the table:ParameterCathete.Bef.

According to our results, significant hemodynamic and clinical improvement in patients with severe heart failure was attained by the correction of mitral and tricuspid insufficiency. It may serve as a bridge to heart transplantation. Early correction of mitrotricuspid regurgitation slows down progression of myocardial insufficiency
Numerical and experimental aspects of thermally induced vibration in real rotors
No full textTemperature fields in electric energy generators may lead to mechanical
dissbalance of an already balanced rotor. The author collected information in
a number of steam power plants and confirmed the existence of the problem.
This paper is presents the specific case of thermal deformation of the rotor,
caused by an asymmetrical temperature field in scale of rotor. On the grounds
of the relevant physical aspects, we propose a mathematical model identifying
fields in a turbo generator rotor and suggest the optimum control by which
the unwanted effects are eliminated.</jats:p
Defects and Impurities in Colloidal Ga2O3 Nanocrystals: New Opportunities for Photonics and Lighting
No full textDefects, both native and extrinsic, critically determine functional properties of metal oxides.
Gallium oxide has recently gained significant attention for its promise in microelectronics, owing to the unique combination of conductivity and high breakdown voltage, and solid-state lighting, owing to the strong photoluminescence in the visible spectral region. These properties are associated with the presence of native defects that can form both donor and acceptor states in Ga2O3. Recently, Ga2O3 nanocrystal synthesis in solution and optical glasses has been developed, allowing for a range of new applications in photonics, lighting, and photocatalysis. This review focuses on the structure and properties of Ga2O3 nanocrystals with a particular emphasis on the electronic structure and interaction of defects in reduced dimensions and their role in the observed photoluminescence properties. In addition to native defects, the effect of selected external impurities, including lanthanide and aliovalent dopants, and alloying, on the emission properties of Ga2O3 nanocrystals are also discussed.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

Numerical simulation of the influence of stationary louver and coal particle size on distribution of pulverized coal to the feed ducts of a power plant burner
No full textOne of the key requirements related to successful utilization of plasma technology as an oil-free backup system for coal ignition and combustion stabilization in power plant boilers is provision of properly regulated pulverized coal distribution to the feed ducts leading the fuel mixture to a burner. Proper regulation of coal distribution is deemed essential for achieving an adequate pulverized coal concentration in the zone where thermal plasma is being introduced The said can be efficiently achieved by installation of stationary louver in the coal-air mixing duct ahead of the feed ducts of a burner. The paper addresses numerical simulation of a two-phase flow of air-pulverized coal mixture in the mixing ducts, analysing the effects of particle size distribution on pulverized coal distribution to the burner feed ducts. Numerical simulation was performed rising the FLUENT 63 commercial code and related poly-dispersed flow module, based on the PSI-CELL approach. Numerical experiments have been performed assuming a mono-dispersed solid phase with particle diameter ranging from 45 mu m to 1200 mu m. Distance between the louver blades and the resulting effect on the flow profile was analysed as well. Results obtained indicate that the size of coal particles considerably influence the overall solid phase distribution. While fine particles, with diameters at the louver end of the above specified range, almost fully follow the streamlines of the continuous phase, coarser particles, which hit the louver blades, deflect towards the thermal plasma zone. In this manner, a desired phase concentration in the considered zone can be reached For the said reason, installation of stationary louver have been deemed a very efficient way to induce phase separation, primarily due to more pronounced impact of the installed louver on discrete phase flow then the impact on the flow of the continuous phase
