No full textsummary:We consider properties of Tanaka spaces (introduced in Mynard F., {\it More on strongly sequential spaces\/}, Comment. Math. Univ. Carolin. {\bf 43} (2002), 525--530), strongly sequential spaces, and weakly sequential spaces. Applications include product theorems for these types of spaces

For English translation, see sac_nak_0233.The collection consists of documents, diaries, letters, books, calendars, newspapers, photographs, artifacts and audiovisual media pertaining to Kikuyo Morimoto Nakatani, a Japanese-born woman who lived in Isleton, California. During World War II, her family was incarcerated in the Minidoka and Tule Lake incarceration camps. After the war, she moved to Los Angeles and studied tea with Madame Sosei Matsumoto, and became a tea master acknowledged by the Urasenke Headquarters in Japan.

Space charge and charge trapping characteristics of cross-linked polyethylene subjected to ac electric stresses
No full textThis paper reports on the result of space charge evolution in cross-linked polyethylene (XLPE) planar samples of approximately 220 ?m thick. The space charge measurement technique used in this study is the PEA method. There are two phases to this experiment. In the first phase, the samples were subjected to dc 30 kVdc/mm and ac (sinusoidal) electric stress level of 30 kVpk/mm at frequencies of 1 Hz, 10 Hz and 50 Hz ac. In addition, ac space charge under 30 kVrms/mm and 60 kVpk/mm electric stress at 50 Hz was also investigated. The volts off results showed that the amount of charge trapped in XLPE sample under dc electric stress is significantly bigger than samples under ac stress even when the applied ac stresses are substantially higher. The second phase of the experiment involves studying the dc space charge evolution in samples that were tested under ac stress during the first phase of the experiment. Ac ageing causes positive charge to become more dominant over negative charge. It was also discovered that ac ageing creates deeper traps, particularly for negative charge. This paper also gave a brief overview of the data processing methods used to analyse space charge under ac electric stress

Nonequilibrium Critical Casimir Effect in Binary Fluids
No full textColloids immersed in a critical binary liquid mixture are subject to critical Casimir forces (CCFs) because they confine its concentration fluctuations and influence the latter via effective surface fields. To date, CCFs have been primarily studied in thermodynamic equilibrium. However, due to the critical slowing down, the order parameter around a particle can easily be perturbed by any motion of the colloid or by solvent flow. This leads to significant but largely unexplored changes in the CCF. Here we study the drag force on a single colloidal particle moving in a near-critical fluid mixture and the relative motion of two colloids due to the CCF acting on them. In order to account for the kinetic couplings among the order parameter field, the solvent velocity field, and the particle motion, we use a fluid particle dynamics method. These studies extend the understanding of CCFs from thermal equilibrium to nonequilibrium processes, which are relevant to current experiments, and show the emergence of significant effects near the critical point

Introduction
No full textGiven the consolidated position of English as the international language for communication in business and management, this book depicts a wide scenario in which to analyse and compare interactions between eastern/western European users of English, as well as Asian/European/North American speakers. From each chapter, different sociolinguistic realities emerge. They affect English, as used largely by non-native speakers, but also the relationship between local or national cultures and the global professional discourse community.
In this context not only the specialized lexis is analysed, but rather the ways in which different geo-political cultures construe, manifest and establish their identities. Although it is difficult to classify pragmatic usages of language, the six chapters in the first section deal with language and culture following a genre-based approach, whereas the six chapters of the second section specifically consider corporate identity in intercultural interactions.
This volume is the offspring of a two-day seminar as part of the 10th ESSE (European Society for the Study of English) Conference which was held in Turin, August 2010. The objective and spirit of the seminar, as well as of the book, is not to emphasize contrasts, rather to avoid stereotypes and misunderstandings and promote mutual understanding, arising from awareness about different norms of communication
