RESEARCHES ON BOUNDARY LAYER THEORY TO PLANE PROFILE NETWORK CALCULUS.
This paper mainly shows U.C.M.R.’s research regarding the application of boundary layer theory to the optima profile network calculus used for manufacturing the runner blades of axial turbines. The way in which the results obtained in boundary layer and turbulence theory can be used in profile network calculus will be indicated herein. Through the researches regarding the optimization of profile network by boundary layer theory namely the designing of network with minimum losses there were also achieved two important stages: the establishment of an optimized velocity distribution on the extrados profile and the achievement of corresponding profile from the network. At the end work we passed on to the application of the method for designing an optimized blade of axial turbine, of generating network concretely, on the basis of obtained results.

APPLICATIONS OF CASTING PROCESSES SIMULATIONS USING MAGMA SOFT.
One of the most performing simulation program for casting and metal solidification is MagmaSoft, program used for the tests presented below. Using MagmaSoft we can test a very large amount of options, avoiding in this way the geminating work and spare a lot of time and money. Based on the simulation results, it was realized a technology that allows the casting of balls made of austenitic manganese steel in a particular way that place the casting defect in the central part of the sphere.

THE ALUMINIUM PLASMA WELDING.
The plasma welding procedure is a relatively recent developed procedure. But, at the outlet from the discharge space, the plasma jet is restraint to pass through a reduced hole, that leads to an arc restraint, resulting a rapid increase of the density of energy.

THE WELDING IN THE CARBON DIOXIDE PROTECTIVE MEDIUM USING HIGH CURRENTS
Once with the introduction of the welding in the CO2 medium, continuous efforts are made for the procedure to be improved and the economy to be increased. By this notion we refer to the melding in the protective gas medium, with high current densities, i.e. high strength of the current reported to the wire diameter.

PLANING OF AN EXPERIMENTAL STALL FOR SHAPE MEMORY ALLOY.
The experimental study of some materials with shape memory alloy (Germ. Formgädechnis-Legierung FGL, Franc. Alliages a memoire AM) presents interest thanks to the practical application in different technical fields. This paper presents an experimental stall for testing some wires with shape memory (f.e. Ni-Ti alloy) that allows a determination from the characteristics of length or electrical resistivity in function of temperature with evidence of the hysteresis limit.

A STUDY CONCERNING THE BEHAVIOUR OF THE LADDLE FURNANCE SUPPLIED BY THE ENERGETIC SYSTEM OF SC.CSR.SA FROM THE POINT OF VIEW OF THE DISTORTING CONDITIONS AND OF THE VOLTAGE VARIATION.
The present study treats the behaviour of the L.F. towards the electrical energy supplying sourse of the installation. The importance of the analysis of the effects produced by L.F. on the supplying sourse is bigger when the aggregat is electrically connected on the 6kv bar of the enrgetic system of SC.CSR.Sa, bars upon which are flowing energetic stations.

EXPENSION LOOP OF THE COMMAND ANGLE TRANSFORMATION DEPENDENT ON THE FREQUENCY VARIATION OF THE NETWORK AT THE THYRISTOR CHANGERS TYPE ATR.
A functioning thyristor can be assimilated with an on-off switch of a certain frequency and of a certain logic that should satisfy as much as possible the consumers supplied from a network through it. Basically, the setting of the ignition point is obtained comparing two voltages, one being given by a controller and the other one by a block, that takes as a reference element the voltage applied to the thyristor hub/lug or a tact reference, if certain logical conditions required by the equipment are completed.

This paper solves a problem that has created difficulties to the LDS section once high and frequent voltage frequency fluctuations appeared in the supplying system. The application of the study requires great constructive changes of the electronic blocks from the CИØУ system as well as changes within the internal links of the converters. The solution can be applied to all the subunities in the country equipped with power electronic equipment similar to the ones existing within the L.D.S. section.

INSULTS IN LITERATURE
The importance of insults in literature is described. Writers, not surprisingly, have produced some of the most devastatingly clever, contemptuous and witty insults. William Shakespeare is in a league of his own when it comes to insulting wit. We deal with three kinds of insults: insults uttered by the writers in their works, insults uttered by critics, which we very much like to call ‘rotten reviwes’ and the battle between writers and critics, their ‘guns’ being simple word, sometimes uttered in a rather malicious way.

DORIS LESSING - A MODERN WRITER
This short biography presents the importance of Doris Lessing’s work. The first part of the paper presents some biographical aspects of this great writer. The second part emphasizes her literary career. It is difficult to succeed in telling ”everything that is important” about such a great writer because when talking about Doris Lessing every little detail has its own importance. Her complex personality and the greatness of her work can be studied in thousands of papers and there could be still something new to say about her.

VOLTAIRE – UN GRAND REPRÉSENTANT DES LUMIÈRES
L’article présente Voltaire comme le plus grand représentant du siècle des Lumières, c’est pourquoi le XVIII-ème siècle est nommé aussi « le siècle de Voltaire ». L’œuvre voltairienne contient les grands thèmes du siècle des Lumières : le pessimisme et le bonheur . L’accessibilité du texte voltairien est remarquable parce que tous ses personnages parlent la même langue et ils n’ont aucune difficulté de communication même s’ils viennent des pays différentes.Voltaire a eu une activité prodigieuse et de nos jours il reste le symbole de l’esprit français.
