Side milling capability of rock cutting tools
Currently, the deviating hole drilling occupies a leading role in Russia. Directional drilling is used when the wells for oil and gas in Western Siberia, in the north of the European part, in the North Caucasus, in Tatarstan, Bashkortostan, Samara region and other areas are drilled, as our regions have a vast number of factors interfering with conventional drilling.
Creation of Ceramic Nanocomposite Material on the Basis of ZrO2-Y2O3-Al2O3 with Improved Operational Properties of the Working Surface
In article questions of receiving high-strength ceramics on the aluminum oxide and zirconium dioxide nanopowders basis are considered. As questions of strength properties increase of a ceramic samples surface are studied by ionic implantation methods.
The politics of becoming bodies: Sex, gender and intersubjectivity in motion
Abstract This paper presents readers with one (research) story about (sexed and gendered) bodies not as objects with inherent boundaries and properties but as material-discursive phenomena. In telling such a story I examine the role that the screendance, Becoming Bodies , has played in knowledge production and argue for a less ontologically ‘old fashioned’ view of what counts as ‘evidence’. Throughout the paper I draw from a range of feminisms: biological, phenomenological, poststructural, psychoanalytical, and post humanist and performative scholarship of sex and gender. These discourses contest nature/nurture, male/female, body/mind dualisms, and take the political and ethical view that bodies are not neutral; that sex and gender, being a woman or a man are both socially and biologically constructed forms of identity (similar to class and race) that are acquired and learned through socio-cultural regimes of discipline and intersubjective bodily practices. Building on this dynamic and developmental bio-psycho-social view I discuss selected aspects of interview data: (1) the material-discursive tensions and contradictions of sexing and gendering bodies and (2) troubling the intersubjective implications of this for clinical practices.
