VIDRARU RESERVOIR, ROMANIA. ENVIRONMENTAL IMPACT OF THE HYDROTEHNICAL CONSTRUCTIONS ON THE UPPER COURSE OF ARGES RIVER
Laura Ana MITITELU
Lakes reservoirs and ponds , 2010,
Abstract: Having an important hydrographic system, with a significant discharge potential and being located in a place that has all the forms of relief, the basin Arges is, at present, one of the most complex hydroelectric facilities from all the rivers with reservoirs in the country. Vidraru reservoir is the biggest of its 11 reservoirs. The information (data) about the management of the water in Walachia dates from the year 1576, and the oldest writing about protection against floods is known as the “Ipsilantis canal”, which stated that the big waters of Dambovita river were deviated at Lunguletu in the riverbed of Ciorogarla rivulet and dates from 1774.The effects caused by the hydrotehnical constructions on the environment are numerous and profound, both positive and negative. In this essay, the analysis of the environmental impact of the hydrotehnical facilities on Arges River is made from two perspectives. The first method of analysis is the Water Directive 2000/60 and the second method is basd on a SWOT analysis, a method taken from the economy, but very efficient in establishing the current state, and also the perpective of this environemental impact.
PUBLIC ADMINISTRATION REFORMS IN TRANSITION COUNTRIES: ALBANIA AND ROMANIA BETWEEN THE WEBERIAN MODEL AND THE NEW PUBLIC MANAGEMENT
Denita CEPIKU,Cristina MITITELU
Transylvanian Review of Administrative Sciences , 2010,
Abstract: A general trend is easily observable in the literature on public administration reforms in postcommunist countries and it consists in analyses of the degree of adoption and success of the New Public Management (NPM) model. Relevant implementation gaps for some levels as well as areas of reform, which cannot be ascribed to the NPM in these countries, are highlighted. The combination of these two features – also common, and not by accident, to other Continental European countries – may well be read as the adoption of a modernization framework different from the NPM, which some authors have come to recognize as the New Weberianism. Nonetheless, both models are not suf ciently developed and analyzed to provide a framework for evaluating country experiences. Therefore, the paper will rstly perform a systematic review of the literature on the context and cultural dependency of public management reforms, the debate on the NPM and the New Weberianism, with the aim of de ning an analytical theoretical framework suitable for the analysis and comparison of country experiences; secondly, undertake an in-depth evaluation of public management reform trends in two countries – Albania and Romania – and contrast these with OECD countries’ experience. Public administrations of some European countries, including Albania and Romania, are not NPM “laggards” but have instead chosen to adopt a different modernization model: i.e. the New Weberianism. Implications for future research and policy-makers are drawn.
Hyponymy Patterns in Romanian
Verginica Barbu Mititelu
Memoirs of the Scientific Sections of the Romanian Academy , 2011,
Abstract: Hyponymy is a lexical-semantic relation that has been studied in Romanian linguistics only occasionally and almost exclusively in connection to other relations. However, for computational engineers it offers a very effective way of organizing the lexical material useful in many applications involving Natural Language Processing. In this paper we present two methods of identifying Romanian hyponymy patterns, their results and evaluation; we also envisage the applicability of these patterns and future work.
Efficiency for multitime vector variational problems on Riemannian manifolds involving geodesic quasiinvex functionals
Stefan Mititelu,Madalina Constantinescu,Constantin Udriste
Mathematics , 2015,
Abstract: We study the connection between a multitime scalar variational problem (SVP), a multitime vector variational problem (VVP) and a multitime vector fractional variational problem (VFP). For (SVP), we establish necessary optimality conditions. For both vector variational problems, we define the notions of Pareto efficient solution and of normal efficient solution and we establish necessary efficiency conditions for (VVP) and (VFP) using both notions. The main purpose of the paper is to establish sufficient efficiency conditions for the vector problems (VVP) and (VFP). Moreover, we obtain sufficient optimality conditions for (SVP). The sufficient conditions are based on our original notion of $(\rho ,b)$-geodesic quasiinvexity.
Efficiency and duality for multiobjective fractional variational problems with (ρ,b) - quasiinvexity
Mititelu ?tefan,Stancu-Minasian I.M.
Yugoslav Journal of Operations Research , 2009, DOI: 10.2298/yjor0901085m
Abstract: The necessary conditions for (normal) efficient solutions to a class of multi-objective fractional variational problems (MFP) with nonlinear equality and inequality constraints are established using a parametric approach to relate efficient solutions of a fractional problem and a non-fractional problem. Based on these normal efficiency criteria a Mond-Weir type dual is formulated and appropriate duality theorems are proved assuming (ρ,b) - quasi-invexity of the functions involved.
THE STUDY OF WATER QUALITY USING BENTHIC MACROINVERTEBRATES AS BIOINDICATORS IN THE CATCHMENT AREAS OF THE RIVERS JIU, OLT AND IALOMI A
Elena Daniela MITITELU,Milca PETROVICI,R?zvan Liviu P?RVU
Annals of West University of Timi?oara : Series of Biology , 2012,
Abstract: The wide distribution of benthic invertebrates and their different sensitivity shown upon modifying the qualitative parameters of aquatic ecosystems led to a frequent use of these group as bioindicators in different studies. The present study aims at presenting a list concerning the different macroinvertebrates identified in the larva stage in three watersheds (Jiu, Olt, Ialomi a) and establishing the water quality of the monitored sections using this benthic macroinvertebrates. The sample collecting points were represented by 23 stations. The abundance and frequency values recorded for benthic communities varied according to the physical-chemical conditions specific to each sample collecting station. There were identified 15 groups in total. The most frequent were Ephemeroptera, Plecoptera, Trichoptera, Diptera (Chironomidae) and others. The deterioration of water quality is marked by the decrease in the biotic index EPT/Ch value.
Parity and time reversal violating nuclear polarizability
V. V. Flambaum,J. S. M. Ginges,G. Mititelu
Physics , 2000,
Abstract: We propose a nuclear mechanism which can induce an atomic electric dipole moment (EDM). Parity and time reversal violating (P,T-odd) nuclear forces generate a mixed P,T-odd nuclear polarizability beta_{ik} (defined by an energy shift U = -beta_{ik} E_{i}H_{k}, E is electric field and H magnetic field). The interaction of atomic electrons with beta_{ik} produces an atomic EDM. We performed an analytical calculation of the P,T-odd nuclear polarizability and estimated the value for the induced atomic EDM. The measurements of atomic EDMs can provide information about P,T-odd nuclear forces and test models of CP-violation.
The Mind-Body Problem Today  [PDF]
Gabriel Vacariu
Open Journal of Philosophy (OJPP) , 2011, DOI: 10.4236/ojpp.2011.11005
Abstract: An old philosophical problem, the mind-body problem, has not been yet solved by philosophers or scientists. Even if in cognitive neuroscience has been a stunning development in the last 20 years, the mind-body problem remained unsolved. Even if the majority of researchers in this domain accept the identity theory from an ontological viewpoint, many of them reject this position from an epistemological viewpoint. In this context, I consider that it is quite possible the framework of this problem to be wrong and this is the main reason the problem could not be solved. I offer an alternative, the epistemologically different worlds perspective, that replace the world or the universe. In this new context, the mind-body problem becomes a pseudo-problem.
