Attractors for Navier-Stokes flows with multivalued and nonmonotone subdifferential boundary conditions

We consider two-dimensional nonstationary Navier-Stokes shear flow with multivalued and nonmonotone boundary conditions on a part of the boundary of the flow domain. We prove the existence of global in time solutions of the considered problem which is governed by a partial differential inclusion with a multivalued term in the form of Clarke subdifferential. Then we prove the existence of a trajectory attractor and a weak global attractor for the associated multivalued semiflow. This research is motivated by control problems for fluid flows in domains with semipermeable walls and membranes.Comment: A correction was introduced in assertion (ii) of Definition 4.4 and - accordingly - in the proof of Theorem 4.

Global attractors for multivalued semiflows with weak continuity properties

A method is proposed to deal with some multivalued semiflows with weak continuity properties. An application to the reaction-diffusion problems with nonmonotone multivalued semilinear boundary condition and nonmonotone multivalued semilinear source term is presented.Comment: to appear in Nonlinear Analysis Series A, Theory, Methods & Application

Uwagi o Owidiuszu i złotym wieku Augusta

Publius Ovidius Naso was an outstanding poet of the Augustan age who after a period of successful activity was suddenly sent to exile without a formal judicial procedure. Ovid wrote frivolous poems but inserted into his works also the obligatory praises of Augustus. The standard explanation of his relegation to Tomis is the licentious content of his Ars Amatoria, which were believed to offend the moral principles of Augustus. However, the Ars had been published several years before the exile. The poet himself in his Pontic writings mentions an unspecified error and a carmen, pointing also to the Ars, without, however, a clear explanation of the reason for his fall. The writer of the present contribution assumes that the actual reason for the relegation of the poet without a trial were the verses of his Metamorphoses and especially the passage about the wicked stepmothers preparing poison. That could offend Livia who, according to gossip, used poison to get rid of unwanted family members. Ovid was exiled, but the matter was too delicate for a public justification of the banishment. When writing ex Ponto the poet could not explicitly refer to the actual cause of his exile.Publius Ovidius Naso was an outstanding poet of the Augustan age who after a period of successful activity was suddenly sent to exile without a formal judicial procedure.

The motif of family discord in Russian second-rate fiction about clergy's life of the 1860s and 1870s

In the present paper the analysis of a motif characteristic of the Church-oriented novels, novelettes, stories and sketches – the motif of family discord – is offered. The examination of several literary works of the 1860s and 1870s has shown that it is the depiction of the negative aspects of clergymen's family life that dominates, the reasons for which being different moral principles, hierarchy of values and major life objectives. Usually it is a priest's wife that is presented as a negative character, although the opposite may be also observed. In the paper both the influence of the literary motif of family discord, popular in the realistic literature, is examined and certain facts of everyday life of the Orthodox clergy are presented in order to show the combination of these factors in the Church-oriented literary works.In the present paper the analysis of a motif characteristic of the Church-oriented novels, novelettes, stories and sketches – the motif of family discord – is offered.

Patent use exception for user-generated inventions

The high-tech corner of the user-innovation scene is dominated by makers. The expansion of the maker movement embraced fields such as robotics, electronics, and 3D printing, where makers are not only hobbyists, but true contributors to technological progress. By contesting the classical paradigm of innovation incentivized by IP protection, they question the established principles of patent law. In consequence, we observe friction between two discrepant approaches and philosophies: open communal workings (making) and closed proprietary operations (patents). In addition to that, changes in IP practice and the dynamic of making provokes concerns about the free use of the patented ideas. The fact of public sharing, even in a form of one “innocent” Internet post, e.g. suggesting (instructing) certain patent improvements, can be sufficient to claim indirect patent infringement or inducement to infringe. The research addressed the question of the applicability of patent excpetions (limitations of the patent exclusivity) that enable defence in patent infringement cases. It also examined those measures with regard to the scope of the freedom-to-operate they provide. In the course of the project it was demonstrated that the communitarian profile of the movement and the uncontrollable dissemination of information do not allow for the movement to fit under the protective umbrella of patent limitations. The study proposes a novel solution within the framework of patent limitations to address free tinkering and the public dissemination of information. Its objective is plain and simple: to free makers from infringing patent rights, from being involved in patent puzzles and from decoding patent claims

Culture and cultural animation in the context of political and business activities

The article is related to competences and tasks of culture animators and culture managers in the contemporary world. Despite the diversity of tasks and functions between them, there are also competencies needed by both. These competencies are essential in solving a number of similar problems encountered in their work. One of the main problems is the issue of "profit", understood in a broad sense far beyond the purely mathematical operation, although referring to the economy as the art of rational management of resources in order to add them together. For both the culture animator and the culture manager, the main idea consists in the multiplication of social resources, social potential, investing in human capital through co-creation of cultural events and programs animating community. It is therefore necessary to redefine the concept of profit (in the context of activity of the culture manager and animator), i.e. the perception of profit in two dimensions – a social and an economic one (a social profit achieved by the efficient use of resources of each type, including financial and social capitals). The ethics of the culture animator and the culture manager relate to many areas: creating educational offer, cultural events and animation activities programming, responsibility for the range of products and services, their safety (in the context of mass culture), building lasting relationships with customers based on trust, quality, and adequate promotion of the projects, programs, products and services, as well as diagnosing social needs. Contrary to what J. Gajda wrote, the objectives of the activity of culture manager and animator, are not set in opposition to each other. In both cases, the objectives cannot be achieved, if the means and methods have been in conflict with the principles of the Code of Ethics. Cultural managers and animators, should inspire the same way of the understanding culture and its role in human life, especially as "Paideia". Only at a later step as a product, but a product of special value, not only attractively packaged. An important issue is also the question of the evaluation of the social impact of the animator’s and manager’s work in the context of the spent funds. There is a lack of effective, objective and measurable indicators for monitoring and evaluating their work. Another problem is the reference to the principles of corporate social responsibility – in the absence of a uniform system of values. The paper was presented at the conference "The Managerial Trends in the Culture Animation", 27th, May 2010
