Modeling of thermodynamic properties mixed-solvent electrolyte solutions is challenging. Reliable experimental data are essential for any model development and parametrization. In this work, a benchmark database (water + methanol/ethanol alkali halide) presented. The available mean ionic activity coefficient (MIAC) vapor–liquid equilibrium (VLE) comprehensively collected critically evaluated 61...

Virtual Learning Environments (VLE) have become popular in higher education in recent years due to their ability to provide additional and flexible solutions for students and researchers. However, the limitations of VLEs have led to the development of a new generation of VLE – the Personal Learning Environment (PLE). PLEs avoid these limitations and have new features that allow students to cont...

This documental case study was performed using a qualitative approach, and analyzed the dialogues of Nursing students in a context mediated by an educational chat in a Virtual Learning Environment (VLE). The data consisted of eight discussions among students, professors and monitors of the Rio Grande do Sul Federal University College of Nursing on the TelEduc® VLE chat on the activity called Vi...

The effect of various salts such as magnesium nitrate, calcium nitrate, zinc nitrate, and magnesium chloride on vapor−liquid equilibrium (VLE) of the ethyl acetate−ethanol system was studied experimentally in a modified Othmer still at atmospheric pressure. The influence of cation and anion of the salts on the VLE of the ethyl acetate− ethanol system was examined. It was observed that the order...

The various reforms of the health care system aim at reducing the corresponding costs. So the hospitals must rationalize their costs while guaranteeing a good quality of service. In order to reach this goal, different scenarios of health care unit management have to be envisaged and carefully evaluated before their implementation on the system. Thus, simulation is used more and more frequently ...

The trend with organisational adoption of virtual learning environments (VLE) seems to be cyclical. Initially, a decentralised approach was adopted, wherein each department implemented different learning environments or mixtures of technology, often developed in-house. The last five years have seen an increased centralisation of learning environment implementation, with most universities adopti...

This chapter discusses theoretical, methodological and practical aspects of a design of a university learning environment for SMART education. Smart technology is analyzed against university background. The authors consider a process of transformation from e-learning to smart education, in particular the VLE objective according to the concept of smart education, formation of individual learning...

In recent years, Virtual Learning Environments (VLE) (also known as Learning Management Systems) have become pervasive in Higher Education. In addition, the explosion in social software and Web 2.0 technologies raises learners’ expectations of flexibility and personalisation, and highlights the rigidity and limitations of the VLE. Recognition of these limitations has given rise to the evolution...
