ANNUAL FINANCIAL STATEMENTS - A SOURCE FOR THE FINANCIAL DSECISIONS OF INSOLVENT COMPANIES

The paper presents the importance of financial statements in determining the insolvency of a company. The first part of the article presents a case study and the main signals of bankruptcy: negative working capital, negative equity capitals, losses, etc. In the end of the paper we detail issues that are not observable and that are related to the actual management of the company.working capital, working capital need, treasury, equity capitals, annual financial statements

Operating Cash Surplus Determinations

The paper defines the concept of operating surplus. Then, it is compared to the gross operating surplus and the differences are identified. The two calculation methods are presented next: (1) operating revenue less operating charges and (2) the gross operating surplus less WCN (Working capital needs) less immobilised production less stored production less other operating revenues). Then, a three year study is presented (2005-2007) and the results are interpreted. Then, there is a correlation between the operating cash flow surplus and the operating cash flows.operating surplus, operating revenue less operating charges, the gross operating surplus less

ON THE PERFORMANCE OF ROMANIAN COMPANIES AND PARTNERSHIPS

This article is structured as follows: definitions of performance, profit - the main performance indicator and a case study on how the main performance indicators in the case of the company “X” were calculated.performance, profit, gross profit, net profit, operating profit, turnover, added value, gross operating surplus

Kinetically modified parametric instabilities of circularly-polarized Alfven waves: Ion kinetic effects

Parametric instabilities of parallel propagating, circularly polarized finite amplitude Alfven waves in a uniform background plasma is studied, within a framework of one-dimensional Vlasov description for ions and massless electron fluid, so that kinetic perturbations in the longitudinal direction (ion Landau damping) are included. The present formulation also includes the Hall effect. The obtained results agree well with relevant analysis in the past, suggesting that kinetic effects in the longitudinal direction play essential roles in the parametric instabilities of Alfven waves when the kinetic effects react "passively". Furthermore, existence of the kinetic parametric instabilities is confirmed for the regime with small wave number daughter waves. Growth rates of these instabilities are sensitive to ion temperature. The formulation and results demonstrated here can be applied to Alfven waves observed in the solar wind and in the earth's foreshock region.Comment: 9 pages, 4 figures, accepted to Physics of Plasma

Remarks on nonlinear relation among phases and frequencies in modulational instabilities of parallel propagating Alfven waves

Nonlinear relations among frequencies and phases in modulational instability of circularly polarized Alfven waves are discussed, within the context of one dimensional, dissipation-less, unforced fluid system. We show that generation of phase coherence is a natural consequence of the modulational instability of Alfven waves. Furthermore, we quantitatively evaluate intensity of wave-wave interaction by using bi-coherence, and also by computing energy flow among wave modes, and demonstrate that the energy flow is directly related to the phase coherence generation.Comment: 17 pages, Nonlinear Processes in Geophysics (published), the paper with full resolution images is http://www.copernicus.org/EGU/npg/13/npg-13-425.pd
