Observations of the causes and effects of the avalanches in the Piatra Craiului Massif
MADALINA TEODOR
Cinq Continents , 2011,
Abstract: Observations sur les causes et les effets des avalanches en Massif Piatra Craiului. Les avalanches représentent un hazard naturel qui se manifeste comme un glissement imprévu, dans des distances plus que 50 metres d’une quantité grande de neige, qu’arrive dans les pentes montaignes après la rupture de l’equilibre de la neige (qui a des causes diverses: climatiques, mécaniques, anthropique). Il est un de premiers agents responsables de la modélisation de relief dans l’ étage cryo-nival du massif Piatra Craiului. Les régions favorablespour la formation d’avalanches sont representées par la partie supérieure des vallées torrentieles où arrivent des conditions potentielles (la pente, la manque de la vegetation, le vent, l’exposition du pentes, l’accumulation de la neige, les conditions meteorologiques etc). L’importance d’evaluer et de surveiller les avalanches n’est d qu’elles peuvent se transformer dans un événement mena ant qui présente la probabilité à se produire dans une certaine période, étant nuisible pour l’homme, pour les bons produits par il et pour l’environnement.
EXCHANGE EFFECTS AND SECTORIAL ROTATION ROLE IN SELECTING FINANCIAL SECURITIES PORTFOLIOS
MADALINA RADOI
International Journal of Economics and Research , 2011,
Abstract: The development strategies of large companies are marked, after the beginning of the ‘90s, by two major evolutions as compared to the industrial and financial consolidation processes: on the one hand, the activities refocusing on basic materials, and on the other hand, the acceleration of the internationalization of activities connected to the market globalization. These evolutions are mostly the consequences of a logical upheaval of portfolio selection. Such an approach has led to privileges within priorities of choosing investment sectors before the geographical choice(Berdot J.P. et al. (2001), Cavaglias et al. (2000), Forbes and Chinn (2003), Emiris M. (2004)).
External Balance Payments – Macroeconomic Analysis Instrument
Madalina Dumbrava
Theoretical and Applied Economics , 2006,
Abstract: The foreign trade activity represents, on one side, the participation of one country to the international economic co-operation, on the basis of the labor international division as well as, on the other side, a factor of economic growth. The sold of the payments balance shows to what extent a country depends on external relationship. The foreign payments balance is conceived as an instrument of economic analysis, reflecting the actual financial flows, which are being established. In the paper we are dealing with the forms in which the payments balance is made, as well as the recording principles for its data. By its own structure, the foreign payment balance emphasizes the debts and the commitments undertaken by a country, within a given period of time. Aspects such as: the equilibrium of the payments balance; tehnicques meant to secure the equilibrium of the payments balance and policies meant to secure the equilibrium of the payments balance are also approached as an attempt to clarify the subject.
Analyzing the Network Response Time and Load Balancing

Abstract: This paper describes the network response time which represent a significant indicator for network performance and how load balancing can improve the network performance.
POLITICAL IMPACT ON THE OBSERVANCE OF PENSION RIGHTS IN ROMANIA
MADALINA TOMESCU
Challenges of the Knowledge Society , 2011,
Abstract: The beginning of 2011 brought some questions for all the persons-romanian citizen – beneficiaries of the pension rights , but also for the middle age persons, which feel a threat for their right to pension. I propose to research the way that the pension right is influenced by the political decision taken by the party temporary governing. Also, I propose to identify the possible effects of these decisions.
THE PUBLIC PENSION POINT - A GOVERNMENT BUSINESS
MADALINA TOMESCU
Challenges of the Knowledge Society , 2013,
Abstract: Each of us pays every month a percentage of his/her salary for receiving a public pension after a certain age. As a percentage, this amount of money varies depending of salary. But retirement means a number of pension points. Where is the business? Pension point is determined by the Government as a percent of medium salary. This article aims to make an analysis of pension point as a government business.
CONSIDERATIONS ON THE RELATIONSHIP BETWEEN PRODUCER AND CONSUMER ON FOOD MARKET
MADALINA DINU
Challenges of the Knowledge Society , 2012,
Abstract: Perhaps one of the largest legislative climbing in recent years is shaped by the instruments that Romanian legislator puts at hand in order to protect its consumers from potential abuses of the producer. The importance of rules of such liability producer is justified primarily by the fact that a modern democratic society, consumer protection has become an essential part of the whole system of social protection. Moreover, the consumer's right to health and safety of its community is a constitutional principle, a consumer is considered by the Community forums as a new form of citizenship.
On the properties of the Volkov solutions of the Klein-Gordon equation
Madalina Boca
Physics , 2011, DOI: 10.1088/1751-8113/44/44/445303
Abstract: We present an elementary proof based on a direct calculation of the property of completeness at constant time of the solutions of the Klein-Gordon equation for a charged particle in a plane wave electromagnetic field. We also review different forms of the orthogonality and completeness relations previously presented in the literature and we discuss the possibility to construct the Feynman propagator for the particle in a plane-wave laser pulse as an expansion in terms of Volkov solutions. We show that this leads to a rigorous justification for the expression of the transition amplitude, currently used in the literature, for a class of laser assisted or laser induced processes.
Trajectory trapping and the evolution of drift turbulence beyond the quasilinear stage
Madalina Vlad
Physics , 2012,
Abstract: Test modes on turbulent magnetized plasmas are studied taking into account the ion trapping that characterizes the E x B drift in the background turbulence. We show that trappyng provides the physical mechanism for the formation of large scale potential structures (inverse cascade) observed in drift turbulence. Trapping combined with the motion of the potential with the diamagnetic velocity determines ion flows in opposite directions, which reduce the growth rate and eventually damps the drift modes. It also determine transitory zonal flow modes in connection with compressibility effect due to the polarization drift in the background turbulence.
Aspects of Costs Calculation in a Vegetable Production Farm
Teodor HADA
Risk in Contemporary Economy , 2012,
Abstract: This paper deals with the aspects of the issue of costs calculation for a vegetable production farm in terms of theory and practice. Aspects of the active accounting regulations, applicable to vegetable production farms, are presented in the content. Features of the vegetable production are detailed, and the applicability of costs calculation methods is shown by the example of the “to order” method. In terms of accounting, there are presented the records made in the management accounting, in the financial accounting and also the conclusions to be drawn in terms of management accounting utility in financial decision making.
