Modification of surface layers by high energy treatment by M. N. Vereschagin, S. N. Tselueva, M. Yu. Tseluev

“…The nature of heating, which is determined by the rate of change of temperature, temperature gradients, the time to reach the temperatures of structural and phase transitions, is different depending on the properties of the material being processed and the processing conditions.When modifying the surface layers by high-energy processing by changing the power and time of exposure to laser radiation, you can get a wide range of structural states of the treated surface areas of the material.It is shown that the shape of TVP diagrams and cooling curves of precision alloys on the surface of a two-layer metal system after heating them with laser radiation are determined by the competition of two processes acting in opposite directions: an increase in the driving force of the crystallization process with an increase in supercooling and a decrease in the surface of atoms.The method of surface modification by moving laser radiation allows to obtain amorphous functional layers of precision alloys on the surface of metal products.…”

Les insectes vivants dans l’espace anthropisé. Incarnations de la dichotomie nature/culture en architecture by Delphine Lewandowski

“…Living insects are part of an unthought field of nature in architecture, as they are often considered undesirable, but also because of scale, space, and time issues. The dichotomies that are associated with them: “desirable/undesirable”, “controlled/uncontrolled”, or “fascination/repulsion”, illustrate the impact that naturalism has on contemporary architectural culture and its production, at a time when the integration of the living in the built environment is increasingly desired and standardized. …”
