Poly (dimethyl siloxane) - based composite nanofiltration membranes for non-aqueous applications

This thesis presents a systematical experimental study performed in order to identify the key parameters that could affect the membrane transport characteristics through poly(dimethyl siloxane) (PDMS)-based SRNF membranes. A complete understanding of the solvent, solute and membrane characteristics that influence the solvent/solute flux through the membrane could form the foundation for a modeling approach capable of predicting the membrane performances

THE ROLE OF CRITICAL THINKING, ACADEMIC ENTREPRENEURSHIP AND TALENT IN THE ECONOMIC DEVELOPMENT

In general sense, the mission of universities has not traditionally involved a consciousness of the need to be wealth creating in the direct sense. However, the rise of the knowledge economy has forced them to become aware of the importance they have for the establishment of future regional ‘constructed advantage’. They have become vital actors in the knowledge society and economy. It is important however to take a broader view that includes use of university capabilities in support of economic development, public and social policy, cultural engagement. Cultural activity and industries are important for economic activity, science is part of our culture, the social sciences have roles in all three domains, and all three areas interact strongly. Consolidate links to different stakeholders (stakeholders include students as key members of the academic community, government at all levels, enterprise and business, different social and cultural actors), universities must respond to their needs through teaching, research and dissemination of results and knowledge transfer activities which serve to promote economic growth and competitiveness through creating and exploiting new knowledge.Constructed advantage; University; Talent; Critical thinking; Economic growth.

Membrane structures and their use in civil engineering

This paper is focused on the static analysis of membrane structures, which are typical for their ability to transfer only tensile forces. Membrane structures are becoming more popular owing to their lower initial cost and potential for use in structures with higher aesthetic claims. However, the designs of membrane face some challenges related to the specific properties of these support systems. This paper aims to analyse the current possibilities for using membrane structures and to evaluate these structures in terms of materials and design details and using numerical methods

ASSESSING THE EFFECTIVENESS OF COMPETITION POLICY IN ROMANIA USING CLUSTERS AND DISTANCES METHODS

For European competition policy, assessing the effectiveness of its enforcements turned out to be a problematic issue. Thus, it has proved to be difficult to assess whether the objectives are properly defined and subsequently the extent that these were achieved, whether the institutional and legal framework are well chosen and ultimately whether the actions of competition authorities produce the desired outcome as long as the performances of these institutions are not quantified in one way or another. Based upon clusters and distances methods this paper highlights the main disparities between Romania and other Member States regarding the perceived effectiveness of competition policy enforcement. Which seems to be obvious for Romania is the fact that it has the legal and also the institutional framework required to ensure a normal competitive environment, but unfortunately it is not credible and therefore is not considered as an improving competitive environment factor as long as its effects on the market are elusive for companies and consumers.competition policy, effectiveness, clusters, distances

Research and Development as a Determinant of Services Sector Competitiveness

Innovation in services has traditionally been neglected in the literature, perhaps because of the assumption that services do not innovate or are primarily users of innovation in manufacturing. In reality, services do innovate in both processes and products, but much of this innovation does not involve formal research. Nevertheless, innovation in services is important for development and Romania is facing the challenge to ensure the most effective connection with global research networks and the innovation systems of other countries.services, innovation, competitiveness;

KELAYAKAN MEDIA PEMBELAJARAN (BOOKLET) PADA SUBMATERI KONSEP PERTUMBUHAN DAN PEMBANGUNAN EKONOMI KELAS XI DI SMA NEGERI 1 SENGAH TEMILA

Learning media is a means to convey the contents of the material, making it easier for teachers to convey the contents of the subject matter, making it easier for teachers to convey messages or to students. One model of learning media is a learning resource that contains material, as well as pictures related to the material that will be delivered by the teacher, with this media it can help students understand the material in an easy way and can attract students' interest. One of the learning media used is booklet media where a booklet is a book that has a minimum of 5 pages but no more than 48 pages on the cover count. This study aims to determine the feasibility of media booklets in the sub-matter of economic growth and development and to determine students' perceptions of media booklets in class XI SMA Negeri 1 Sengah Temila. The research method used is descriptive analysis method in qualitative research and the data collection technique used is interviews. The results showed that the booklet learning media made for the material on the concept of economic growth and development at SMA Negeri 1 Sengah Temila is appropriate for use in the learning process

A practical approximation algorithm for solving massive instances of hybridization number for binary and nonbinary trees

Reticulate events play an important role in determining evolutionary relationships. The problem of computing the minimum number of such events to explain discordance between two phylogenetic trees is a hard computational problem. Even for binary trees, exact solvers struggle to solve instances with reticulation number larger than 40-50. Here we present CycleKiller and NonbinaryCycleKiller, the first methods to produce solutions verifiably close to optimality for instances with hundreds or even thousands of reticulations. Using simulations, we demonstrate that these algorithms run quickly for large and difficult instances, producing solutions that are very close to optimality. As a spin-off from our simulations we also present TerminusEst, which is the fastest exact method currently available that can handle nonbinary trees: this is used to measure the accuracy of the NonbinaryCycleKiller algorithm. All three methods are based on extensions of previous theoretical work and are publicly available. We also apply our methods to real data
