A stronger Bell argument for quantum non-locality
No full textIt is widely accepted that the violation of Bell inequalities excludes local theories of the quantum realm. In this paper I present a stronger Bell argument which even forbids certain non-local theories. The remaining non-local theories, which can violate Bell inequalities, are characterised by the fact that at least one of the outcomes in some sense probabilistically depends both on its distant as well as on its local parameter. While this is not to say that parameter dependence in the usual sense necessarily holds, it shows that the received analysis of quantum non-locality as “outcome dependence or parameter dependence” is deeply misleading about what the violation of Bell inequalities implies
The Altitude Adaptive Dual Bell Nozzle
No full textThe dual bell nozzle has been found out to be one of the most promising concepts for alti-tude adaption of the nozzle jet. The wall contour inflection linking the base nozzle with the ex-tension provides two stable operating modes, circumventing the area ratio limitation inherent to conventional main stage engine nozzles. During the past decade, numerous experimental as well as analytical investigations have been conducted at the German Aerospace Center for a better understanding and the qualification of the dual bell concept for main stage engine application. Cold and hot flow tests aimed to point out the influence of the geometrical parameters on the flow behavior. The conditions for the transition from sea level to altitude mode and back, the hysteresis between these values, the duration of the transition and the resulting side load genera-tion were of particular interest. The contour optimization results in a trade-off between the tran-sition duration, stability and side load amplitude, all depending on the extension length. Out of the experimental work, it was possible to define the parameters for realistic dual bell nozzle geometries and to conduct an analytical study of the nozzle behavior during ascent of a parallel staged heavy launcher. The additional loss in sea level, the so-called drag effect, was evaluated for the chosen nozzle using DLR’s CFD in-house code Tau. The present paper gives an over-view on current experimental and analytical dual bell research activities

Campylostoma Bell 1858
No full textGenus Campylostoma Bell, 1858 Campylostoma Bell, 1858: 23. Type species. Campylostoma matutiforme Bell, 1858, by monotypy. Remarks. The genus was tentatively included in Cenomanocarcinidae by Guinot et al. (2008: 20). Material examined here corroborates this assignment; Campylostoma represents the youngest (Paleogene, Cenozoic) member of the family.Published as part of Van Bakel, Barry W. M., Guinot, Danièle, Artal, Pedro, Fraaije, René H. B. & Jagt, John W. M., 2012, A revision of the Palaeocorystoidea and the phylogeny of raninoidian crabs (Crustacea, Decapoda, Brachyura, Podotremata) 3215, pp. 1-216 in Zootaxa 3215 (1) on page 57, DOI: 10.11646/zootaxa.3215.1.1, http://zenodo.org/record/524864
Isabelle Bell to Susan Niemcewicz, December 23, 1800
No full textIsabelle Bell wrote to Susan U. Niemcewicz in Elizabethtown, New Jersey. Bell expressed her disappointment in not receiving a line from Susan. She sent Bell Lucretia Rephans subscription epistle, but Susan refrained from writing a letter to her. Bell did not execute any of Susan’s commissions in New York because her time there was short. Miss Resham heard that Mr. B Livingston told his sister, Mrs. J. Livingston that he would offer Bell a salary to live in his house and take charge of his children’s education. Asked if Susan what she thought of her being an author and if Susan would subscribe to a small volume that may have the good fortune to rival the poems of the immortal Scarron.https://digitalcommons.kean.edu/lhc_1800s/1143/thumbnail.jp
