The paper present the product of Romanian conception which was used having remarkable results both for the parietal stabilization concerning some previous lateral faults, and also for the cases when there was a smaller fault ( resection of two ribs) for which it was considered as obligatory the assuring of the stabilization especially because of the patients age or the breathing function alteration as well as the correlation with the international evolution of these category of products, level of biomedical and biofunctional performances, admissibility condition imposed by the European laws in force regarding the fabrication and conunercialization. 

A pole has no possibility of internal evolution it has no time but it can be space distributed. 

The inductive dipole, able to store the inductive subvariety of energy (kinetic, electromagnetic, etc.). It has the possibility of internal evolution. 

It is assumed that, at least initially, the transmission of heat through the laminate from layer 1, (which includes the surface, s), to layer n, (the insulated base of the laminate), is by conduction, since it is assiuned that the laminate, (prior to pyrolysis and the internal evolution of gaseous volatiles), is principally solid with minimal porosity. In this circumstance it is possible to represent a temperature increment between two successive layers within the laminate i and i+7, respectively, as a function of the instantaneous heat flow of conduction, and the specific heat capacity and density of the laminate, (14.4) ...

The transfonnation matrix L is obtained from a nonnal-mode analysis perfonned in internal coordmates [59, ]. Thus, as the evolution of the nonnal-mode coordinates versus time is evaluated from equation (A3.12.49), displacements in the internal coordinates and a value for q are found from equation (A3.12.50). The variation in q with time results from a superposition of the nonnal modes. At a particular time, the... 

Vibrational motion is thus an important primary step in a general reaction mechanism and detailed investigation of this motion is of utmost relevance for our understanding of the dynamics of chemical reactions. In classical mechanics, vibrational motion is described by the time evolution and l t) of general internal position and momentum coordinates. These time dependent fiinctions are solutions of the classical equations of motion, e.g. Newton s equations for given initial conditions and I Iq) = Pq. 

Fig. 2. Time-evolution of the methyl/ethyl C-C distances for both the zirconocene and the corresponding titanocene catalyst. The two curves starting at around 3.2 A represent the distance between the methyl carbon atom and the nearest-by ethylene carbon atom in the zirconocene-ethylene and the titanocene-ethylene complex, respectively. The two curves starting at around 1.35 A reflect the ethylene internal C-C bond lengths in the two complexes.

Acyl halides are intermediates of the carbonylations of alkenes and organic-halides. Decarbonylation of acyl halides as a reversible process of the carbo-nylation is possible with Pd catalyst. The decarbonylation of aliphatic acid chlorides proceeds with Pd(0) catalyst, such as Pd on carbon or PdC, at around 200 °C[109,753]. The product is a mixture of isomeric internal alkenes. For example, when decanoyl chloride is heated with PdCF at 200 C in a distillation flask, rapid evolution of CO and HCl stops after I h, during which time a mixture of nonene isomers was distilled off in a high yield. The decarbonylation of phenylpropionyl chloride (883) affords styrene (53%). In addition, l,5-diphenyl-l-penten-3-one (884) is obtained as a byproduct (10%). formed by the insertion of styrene into the acyl chloride. Formation of the latter supports the formation of acylpalladium species as an intermediate of the decarbonylation. Decarbonylation of the benzoyl chloride 885 can be carried out in good yields at 360 with Pd on carbon as a catalyst, yielding the aryl chloride 886[754]. 

In situations where conserved internal markers caimot be used, such as in spills of essentially pure compounds, the evidence for enhanced biodegradation may have to be more indirect. Oxygen consumption, increases in microbial activity or population, and carbon dioxide evolution have all been used with success.

The theory is initially presented in the context of small deformations in Section 5.2. A set of internal state variables are introduced as primitive quantities, collectively represented by the symbol k. Qualitative concepts of inelastic deformation are rendered into precise mathematical statements regarding an elastic range bounded by an elastic limit surface, a stress-strain relation, and an evolution equation for the internal state variables. While these qualitative ideas lead in a natural way to the formulation of an elastic limit surface in strain space, an elastic limit surface in stress space arises as a consequence. An assumption that the external work done in small closed cycles of deformation should be nonnegative leads to the existence of an elastic potential and a normality condition.

The choice (5.77) for the evolution equation for the plastic strain sets the evolution equations for the internal state variables (5.78) into the form (5.11) required for continuity. The consistency condition in the stress space description may be obtained by differentiating (5.73), or directly by expanding (5.29)... 

The energy conservation equation is not normally solved as given in (9.4). Instead, an evolution equation for internal energy is used [9]. First an evolution equation for the kinetic energy is derived by taking the dot product of the momentum balance equation with the velocity and integrating the resulting differential equation. The differential equation is... 

This equation is subtracted from the conservation-of-energy equation yielding an equation for the evolution of the internal energy...
