Abstract

Purpose

In microfluidic channel fabrication in low temperature co‐fired ceramics (LTCC), one of the biggest challenges is the elimination of channel deformation during lamination. The purpose of this paper is to describe the expected deformation of the substrate and the sacrificial layer (starch powder and 3D printed UV polymerized material) during the lamination process of microfluidic structure fabrication.

Design/methodology/approach

Uniaxial compression and Jenike shear test were used to obtain the mechanical parameters of starch sacrificial volume material (SVM). To determine the stress‐strain characteristics of LTCC a uniaxial compression experiment was conducted. The shape of the laminated LTCC containing embedded channel was modeled by finite element method using the mechanical parameters obtained by the measurements.

Findings

It was found that the choice of SVM plays an important role in channel deformation. A design rule is given considering the channel width and the choice of SVM based on the simulation results.

Originality/value

Until now the lamination step of LTCC technology was only optimized in an empirical way.

Abstract

This chapter aims to provide a short overview about the situation of Roma in Hungary. Starting from the question ‘Who are the Roma, Gypsy in Hungary?’, this chapter introduces several researches on Hungarian Roma. The linguistic groups of Roma are briefly outlined to make it clear how much the Hungarian Roma are heterogeneous. The social situation of the Roma, as minority in Hungary, is also detailed by introducing geographical location and housing and employment regarding to Roma. Based on these general data on Hungarian Roma, this chapter aims to focus on educational situation of the Roma minority in Hungary, including – primary and secondary school education, education in special schools, education in college and university, adult education, school success supporting educational initiatives and programmes like extracurricular programmes. As a summary, this chapter introduces some further researches by short abstracts in order to provide a suitable starting point for those who are willing to get know more about this minority in Hungary.

Abstract

In this chapter, Andrea Óhidy provides an overview of some central issues of the book. First, she shows the similarities in the challenges to increase the participation and success of Roma people in education and lifelong learning in the selected European countries; then, she discusses their policies and support programmes, which, on the one hand, try to improve the social situation of the Roma while promoting minority language and culture, on the other hand. She finds the reason for their similarities regarding the wording, defining and communicating and also concerning the main ideas and concrete projects for possible solutions, in the Roma inclusion policy of the European Union in the frame of the Open Method of Coordination, which has been introduced within the Lisbon Strategy, linked to the idea of lifelong learning. She considers the realisation of these policy measures at national, regional and local levels to have shown only unsatisfactory results until now.
