We talk about the notion of race with Prof. Ewa Ziętkiewicz, MD from the PAS Institute of Human Genetics in Poznań, in light of the “regional continuity” vs. “recent common ancestor” theories.

Phytophthora root and stem rot of soybean is a destructive disease of soybean in Iran. During 1998–2005, 142 isolates from soil and diseased soybean plants were collected and tested. Race identification was made possible by inoculating Rps differential soybean cultivars and lines. Of the 142 isolates tested, 110 isolates belonged to race 1 and 32 isolates belonged to race 3. Race 1 was domi nant in soil and diseased plant samples. There was no variability in virulence of Phytophthora sojae between the areas surveyed.

This paper presents the current study of the distribution of stresses for four-point contact wire race ball bearing. The main aim of this article is to define the most important geometrical rules in a wire-race bearing. The results for bearings of different geometrical parameters are presented. In the study, one also estimates the distribution of internal pressure in particular bearing elements.

One of the most important parameters, crucial to applications of superconductors in cryo-electrotechnique, is power loss. Measurements of losses in superconducting long sample wires require AC magnetic fields of a special geometry and appropriate high homogeneity. In the paper part of the theoretical basis for calculations and a simple design method for a race-track coil set are presented. An example of such home-made coils, with a magnetic field uniformity of about 0.2 % over the range of about 8 cm, is given. Also a simple electronic measurement system for the determination of AC magnetization loss in samples of superconducting tapes is presented.

One of the most powerful ways in which we can globalize knowledge, and sociology, is to figure ways in which leading intellectual figures within insufficiently articulated knowledge cultures might inform readings of the other’s work. With the recent revivals of Antonina Kłoskowska and W.E.B. Du Bois in Polish and US sociology respectively, it is a propitious time to figure the ways in which their scholarship aligns, contrasts, and can mutually transform. In particular, the two are both concerned for how marginalized communities with their associated subjectivities engage dominant cultures, but Kłoskowska works within a national/regional frame and Du Bois a global and racial one. Too, Du Bois theorizes from within that marginalized community, with political pointedness, not from outside it or with any attempt to refrain from value judgements. Finally, while Du Bois blends Marxist accounts with a culturally rich account of Blackness and its others, Kłoskowska offers a more semiotic and intersubjective hermeneutic view of how various fusions of horizons might also create a more open world. Those who extend Kłoskowska’s tradition exemplify that very potential while Du Bois, in his very conditions of existence, made racism’s hardest shell manifest. Figuring exemplars of national and racial leadership might, however, invite powerful figurations of the future, but only when their cultural and political constitutions are made explicit.

This article examines Henryk Sienkiewicz’s proto-racist distinction between the gentry and the commoners in his novel With Fire and Sword (1883–1884). This division, which is believed to be part of the divine world order, credits the commoners with an inferior humanity. It is founded on a set of essentialist beliefs – that social class is inherited, that ‘noble blood’ confers superiority, and that physiognomy bespeaks high birth (you can tell a noblemen or noblewoman by their physical appearance). As the article claims, Sienkiewicz allows no room for a voice questioning those beliefs, let alone exposing their class-bound arbitrariness.
