simulations mostly by physicists of the competition between adult languagessince 2003 are reviewed. The Viviane and schulze models give good and reasonableagreement, respectively, with the empirical histogram of language sizes. Alsothe numbers of different languages within one language family is modeled reasonablyin an intermediate range. Bilingualism is now incorporated into the schulze *** the rate at which the majority shifts from one language to another is found tobe nearly independent of the population size, or to depend strongly on it, accordingto details of the schulze model. Other simulations, like Nettle-Culicover-Nowak, arereviewed more briefly.

Magnetic pulse welding （MPW） is a fast and clean joining technique that offers the possibility to weld dissimilar metals, e.g., aluminum and steel. The high-speed collision of the joining partners is used to generate strong atomic bonded areas. Critical brittle intermetallic phases can be avoided due to the absence of external heat. These features attract the notice of industries performing large scale productions of dissimilar metal joints, like automo- tive and plant engineering. The most important issue is to guarantee a proper weld quality. Numerical simulations are often used to predict the welding result a priori. Nevertheless, experiments and the measurement of process parameters are needed for the validation of these data. sensors nearby the joining zone are exposed to high pressures and intense magnetic fields which hinder the evaluation of the electrical output signals. In this paper, existing analysis tools for process development and quality assurance in MPW are reviewed. New methods for the process monitoring and weld characterization during and after MPW are introduced, which help to overcome the mentioned drawbacks of established technologies. These methods are based on optical and mechanical measuring technologies taking advantage of the hypervelocity impact flash, the impact pressure and the deformation necessary for the weld formation.

This essay traces the tensions between national imaginaries and transnational global media flows of tango,samba,and ranchera film musicals,taking into account their cross-media and intercultural configurations as well as interconnections between these three“transgenres.”From a comparative perspective and by means of a“histoire croisee,”or crisscrossing history,it touches upon developments in early Latin American sound film,Hollywood’s spanish-language films and its Pan-Americanism,spain’s cinematic Hispanoamericanismo,and PanLatin American film *** essay makes a case for the multifaceted trans/national cultural economy of the tango,samba,and ranchera film musical productions during their main phase,in the 1930s and 40s.

采用sanders公司的四打印头快速成型机进行了陶瓷部件的浆料打印成型实验 ,实际测试了所用四打印头快速成型机的打印工作条件 ,考察了石蜡和挥发性介质两种浆料技术路线 ,并采用石蜡为介质制备了钛酸钡陶瓷浆料 ,研究了其流变性能 .实验表明 ,虽然偶联剂的加入可以降低石蜡介质浆料的粘度 ,但是粘度足够低的可打印浆料的固相含量太低 [约 3 % (involume)以下 ] ,打印成型后不能完全烧结 ,因此 ,要通过打印成型出可完全烧结的陶瓷部件便只能采用挥发性液体作为浆料介质。
