Sandman futura

Micro air abrasion is a new modern method for removing decay and old fillings. It is used a fine stream of aluminium oxide powder and compressed air. Micro air abrasion was discovered in 1940 in USA. Sandman’s unique patented whirl system and special hand pieces secure a unique precision and working condition of the aluminium oxide powder. Dentists can obtain optimal results using the unit with a working pressure between 1½ - 3 bars. In comparison, other systems are used pressure working area of 4 - 8 bars

Ambivalence of Time

The physical nature of Time is researched. Time is considered as a set of phenomena that can be divided into two fundamentally different, but interrelated groups (time sides). The first group is connected with the metric properties and topological concepts of space-time manifold, the integral part of which is Time. This side of time integrates it with spatial dimension. The second group includes physical properties connected with spontaneous time coordinate increment of massive particles (the flow of time). It provides the variation of systems and the development of physical processes in the environment. The difference between time and space can be seen here. Thus, time ambivalence (duality) is shown. Time ambivalence is one of the key temporology principles. It is impossible to build an adequate time theory without considering it

The Role of Literary Criticism in the Processes of Canon Formation in the Postmodernity

The 70’s-80’s sociocultural criticism of Western literary canon has dramatically re-shaped the notion of literary canonicity. It has also thematized the problem of literary criticism discourse which generates the interpretative tradition that ensures the endurance of the canonical artworks. As the very notion of canon was challenged, it is an urgent issue to explicate the structure of critical discourse that is capable of literary values production in the postmodern situation of interpretive dissensus. This research investigates the problem of interrelations between postmodern critical discourse and canonical structure. It also explores the role of criticism in explication of hermeneutical potential of a literary canon. Analysis of the critical rhetoric sustains that postmodern criticism is rather engaged with exploration of canonical textuality than with maintenance of literary canons and aesthetic values. While deconstructing the evaluative consensus, it re-approaches the canon as the field of hermeneutical polemics. Postmodern criticism implements the speculative interpretation logic which maintains the canon as a generative source of new methods of reading. As a result, it supersedes the judgment of taste with the hermeneutically productive pragmatics of opinion. The explication of the postmodern critical discourse helps to enhance understanding of the specific critical attention attributed to canonical text in postmodern culture
