The present study pursued the influence of polyelectrolytes based on maleic co-polymers with styrene (NaM-S) and vinylacetate (NaM-VA) under the form of natrium salt, in the tinctorial system consisting of Melana dyed with Victoria Blue B(VVB)-triarylmethane dye using the colour differences (ΔE) as a method evaluate the interactions. Mathematical models of the studied dyeing processes have been developed and the necessary information on their significant factors is produced by means of experiment planning methods, known as Design of Experiment (DoE) or Experimental design. Optimal correlations between the application conditions and the colour differences obtained on Melana-type fibre have also been studied.

Cobalt (II), nickel (II) and copper (II) complexes of 2 - (4,4'-bipyridin -1- ium -1-yl)-1-(4- methoxyphenyl) - 3 -(naphtalen -1 - ylamino) -1,3 dioxopropan -2- ide ligand (Y) were synthesized and analyzed by 'H NMR, FT-IR, UV-Vis, ESl-MS, Fluorescence Spectroscopy and thermal analysis. RacEa peptide is part of the catalitic site of the glutamate racemase which is an attractive antimicrobial drug target. The Affinity-MS was used for studing the interaction between the ligand Y or the nickel complex of ligand Y and the synthetic RacEa peptide. Only the ligand showed binding to the synthetic RacEa peptide in the presence of dithiothreitol (DTT).

Any university which aims at surviving and at being on top or at having a minimum contribution to the progress of knowledge must evaluate itself according to a set of clear evaluation criteria regarding both didactical and scientific activity. The decisive criterion in promotion is represented by the results of the research activities (the number of research contracts and publications). This is also important for the future success of a university, as it helps to attract students of different levels. The Romanian scientific output is far below the country's human potential, Romania ranking below the EU average and also below its neighbours (Hungary, Poland, and Bulgaria). In 2008, none of the Romanian universities classified among the first 500 universities in the world. Once Romania has joined the European Union, the Romanian universities are in direct competition with the European ones. Even the best of them must increase their score in Shanghai Top 500 World Universities at least twice to reach the level of those from the neighborhood. We believe this is mainly because nowadays the research activity in Romania is evaluated according to "original" criteria, specific only to Romania, discouraging the real scientific performance. Besides, the compensation system is hardly a motivating one, merit pay being practically inexistent. This paper puts forward the idea that high performance motivation and initiatives materialized in high quality research work and publications are directly connected to the internal academic structure that pays for this high- quality research publication. We use a comparative approach in an attempt to put Romania face to face to several successful models (the Anglo-Saxon one, continental, the Scandinavian model) which can inspire the decision makers when reforming the functioning of the Romanian higher education system. At the same time the paper identifies several steps which could lead to an increase of the quality of the Romanian academic staff and the Romanian universities prestige.

Since the 1970s, Romania has been facing a range of changes within the demographic behaviour of its population. When being considered together, these changes lead to the shaping of demographic ageing phenomenon. Even though this phenomenon is especially met in the developed countries, in the countries from the former communist block it can be noticed a model of demographic transition that draws closer their demographic behaviour to that of the population from the western countries. After 1990, this phenomenon intensifies and is correlated with factors specific to the transition period: a more and more reduced birth rate, a positive migration growth, a fertility that cannot ensure the replacement of generations etc. Although the demographic ageing phenomenon does not reach the intensity from the developed countries, its effects for the present and future period in Romania should not be neglected and call forth the conduct of research that could highlight its impact on the economic and social development.
