The natural solutions of the time-and energy-independent linear Boltzmann equation with isotropic scattering have been found on A ⊗ B° where A is the interval [a,b] a,b > 0 and B° = [— 1,0[⋃]0,1]. These functions are regular everywhere on A ⊗ B° and they satisfy homogeneous or inhomogeneous boundary conditions. The solutions become uniformly continuous functions on A ⊗ B and have bounded derivatives of any order if the convention for taking limits, [formule], is used. The
construction of the solutions is based on a number of structural properties established by corresponding new theorems. They exhibit invariance properties with respect to translation, partity and scaling transformations.

The contemplated reform, substituting VAT points for social contribution points would not really encourage employment of workers in preference to recourse to machines, but would be unfair to certain categories of businesses and offer advantages to others. Structural transformations, in this way, would be accelerated. In order to increase employment, another conceivable reform would consist in extending the basis of assessment for social contributions to a firm's capital depreciation and profits. But this would be acceptable only if it could be demonstrated that the mesure would not run counter to the necessary renewal of investment. This is very likely, but no judgment should be made without thorough studies of the subject.

Public enterprise and the crisis : trends in the energy and raw material sectors.
The international crisis has led public energy and raw material suppliers to engage in large structural transformations, viz. branching out, take-ouvers both in France and abroad, and setting up consortiums, whereas the adoption of private industry structures and management, blurring the line between both sectors, have resulted in a transfer of functions from one to the other, diminishing the specificity of public enterprise. The phenomenon is partly explained by the international crisis, calling for ideological and political reactions.
A wider coherence of the public sector and a clearer definition of what belongs to overall planning and what to the autonomy of public enterprise will determine the success of the nationalizations.

This research theme for the agrarian question in independent Algeria, structural transformation processes of production and class relations in the agrarian sector of the Algerian social formation with these highlights as are the two agrarian reforms since the independence. The analysis of the agrarian question here contributes essential way inform the evolution of the social formation.Thus, in this research we will aim mainly to capture two particular items that the analysis can be to some extent autonomized: class relations in rural society (in the area agrarian social training); the state intervention in the agrarian question, that is, the line and the agrarian program of political power, the method and means of implementing this program, the constraints encountered and the effects obtained.The unity of approach will result from the fact that analyze the relationship between agrarian classes in view to clarify the terms of the agrarian question which political power is confronted. It will be necessary to expand the scope of investigation to the political context (political and ideological) which raises the agrarian question. We will do this primarily by analyzing the one hand the characteristics of the nationalist movement, on the other hand the general guidelines of the policy of the regime of President Boumedienne. ; Cette recherche a pour thème la question agraire dans l'Algérie indépendante, le processus de transformation des structures de la production et des rapports de classes dans le secteur agraire de la formation sociale algérienne avec ces temps forts que constituent les deux réformes agraires réalisées depuis l'indépendance. L'analyse de la question agraire contribue ici de manière essentielle éclairer l'évolution de la formation sociale. Ainsi, dans cette recherche nous viserons principalement à saisir deux objets particuliers dont l'analyse peut être jusqu'à un certain point autonomisée: les rapports de classes dans la société rurale (dans le secteur agraire de la formation sociale) ; les ...

Classification, De-classification, Re-classification.
The strategies of reproduction and in particular the strategies of re-conversion depend on the objective profit-risks offered to investments in a given state of the institutional instruments of reproduction and of the capital they are to reproduce ; it follows that the recent transformations of the relationship between the different classes and the educational System —which have resulted in the massive increase in schooling and all the corresponding changes in the educational System itself, and all the transformations of the social structure which, at least in part, are due to the transformation of the relationships holding between qualifications and job-openings— are the result of an intensification of competition for educational qualifications. Thus, those fractions of the ruling and middle classes which are richest in economc capital have had, in order to ensure their reproduction, to greatly intensify the use they made of the educational System, constraining the fractions whose reproduction was hitherto ensured chiefly by schooling to intensify their investments in schooling. Hence the inflation of qualifications and their devaluation. As a consequence of devaluation, the broadening of the monopoly of the holders of educational qualifications over positions which were until then open to non degree-holders means that the chief victims of this process are those who go onto the job-market without qualifications. Hence a reinforcement of the way in which schooling predetermines professional career opportunities and of the interdependence of qualification and job-opening. The re-conversion of the economic capital into cultural capital permits the middle classes to maintain the position of its heirs and explains the morphological changes within the middle classes and, in particular, the emergeance of a new type of craftsmen and trade with a high cultural investment.
The hysteresis of the habitus tends to conceal the devaluation of qualifications from the classes which are furthest from the educational System. The other classes can, in order to escape loss of position, either produce new professions more adapted to their social claims, or else modify in accordance with these claims, by a redefinition implying a re-evaluation, those professions to which their qualifications give access. This creative redefinition effect can be observed in professions of sparse distribution and low degree of professionalisation, such as the new sectors of cultural and artistic production and all those professions which ensure the best return on the cultural capital transmitted by the family; consultative occupations, and those of presentation and representation. One can only understand the emergeance of that new petty-bourgeoisie which harnesses to its function as intermediary between the classes new instruments of manipulation by reference to the transformations in the methods of ruling which, since they are concerned to ensure the symbolic integration of the ruled classes, grant more importance to the prescribing of needs rather than the instilling of norms.
The increase in school-attendance underlies a whole group of transformations in the educational System itself; the well-defined boundaries of the old system are supplanted by the vague classifications of a system which sanctions vagueness of aspirations. It is as if the new logic of the educational system and the economic system promoted the maximum postponement of the moment when, by a series of imperceptible degrees, the final balance-sheet of the semi-bourgeois abortive careers is settled at last. Hence the type of structural instability we find in the representation of social identity and aspirations.
The outcome of all the opposing effects of re-conversion and re-classification, is a global movement upwards of the structure of the distribution, between classes and segments of classes, of the wealth which is the stake of competitiveness, the maintenance of order, that is to say of relational property, being therefore ensured by the ceaseless changes in substantial properties.
