Reconstruction of Konrad Zuse’s Z3
No full textPart 9: Reconstruction StoriesInternational audienceThis paper describes the reconstruction of Konrad Zuse’s Machine Z3 by the author Horst Zuse from 2008. Konrad Zuse built the Z3 machine between 1939 and 1941 with some friends and a small amount of support by the government. The main idea for reconstructing the Z3 was to learn how this machine works and how much effort is necessary to build such a machine. Another main topic was to show this machine to the public

Horst Wessel Dachau Street Sign
No full textBlack metal sign reading, 24 Horst Wessel-Strasse.
Information Provided by Michael D. Bulmash: A small metal street sign from the concentration camp of Dachau. The streets in Dachau were named after so-called Nazi heroes, and this particular example identifies the address 24 Horst Wessel Strasse. Horst Ludwig Wessel (1907-1930) was a German Nazi activist who was made a posthumous hero of the Nazi movement following his violent death in 1940. He was the author of the lyrics to the Nazi Party anthem Die Fahnehoch ( The Flag on High ), usually known as the Horst Wessel Song.https://digital.kenyon.edu/bulmash/2251/thumbnail.jp
Porous collagen scaffolds enable endothelial lumen formation in vitro under both static and dynamic growth conditions
No full textAbstract Despite recent advances in the field of tissue engineering, the development of complex tissue‐like structures in vitro is compromised by the lack of integration of a functioning vasculature. In this study, we propose a mesoscale three‐dimensional (3D) in vitro vascularized connective tissue model and demonstrate its feasibility to prompt the self‐assembly of endothelial cells into vessel‐like structures. Moreover, we investigate the effect of perfusion on the organization of the cells. For this purpose, primary endothelial cells (HUVECs) and a cell line of human foreskin fibroblasts are cultivated in ECM‐like matrices made up of freeze‐dried collagen scaffolds permeated with collagen type I hydrogel. A tailored bioreactor is designed to investigate the effect of perfusion on self‐organization of HUVECs. Immunofluorescent staining, two‐photon microscopy, second‐harmonic generation imaging, and scanning electron microscopy are applied to visualize the spatial arrangement of the cells. The analyses reveal the formation of hollow, vessel‐like structures of HUVECs in hydrogel‐permeated collagen scaffolds under both static and dynamic conditions. In conclusion, we demonstrate the feasibility of a 3D porous collagen scaffolding system that enables and maintains the self‐organization of HUVECs into vessel‐like structures independent of a dynamic flow
Art History and Prehistoric Art: Rethinking their Relationship in the Light of New Observations: The Twentieth Horst Gerson Lecture held on October 4, 2019
No full textThe Twentieth Horst Gerson Lecture held in memory of Horst Gerson (1907-1978) in the aula of the University of Groningen on the 4th of October 2019
The point, from which we are defining the human ability to design artefacts and use symbolic signs is currently shifting to a more distant past. The insights responsible for this pushing back, are based, for example, on findings of very early human-shaped sculpture in Swabia, on the realization that human sign-making started literally hundred thousand years earlier than previously thought, as well as the realization that even hand-axes could carry symbolic meaning. Taken together, these phenomena call for a redefinition of the anthropos, in which the ability to design plays an eminent role. The lecture aims to show how the capacity to discriminate and creatively employ visual and material difference in the environment was a pre-condition for the development of human kind. Against this background, the question rises, if the fruitful collaboration between the fields of aesthetics, art history, and anthropology, that drove nineteenth century research into the origins of human creativity, can be revived.

Upper Silesia as a Myth and Utopia in the Works of Horst Bienek
Abstract: Horst Bienek was a very well known and influential personality in the literary circles in Germany. His works are also important for the history of Silesian literature because of his role in the intraGerman and German-Polish discourse about the homeland, history and identity. In the article the author presents poetical strategies and methodology which Bienek used while creating his mythic representations of Silesia and (at the same time) of himself.Keywords: literary history, German literature, Silesian literature, Horst Bienek, utopiaFor an abstract in English, scroll down.Daniel Juliusz PietrekUniwersytet OpolskiWydział FilologicznyInstytut Filologii Germańskiej
„Wtedy przyjdzie ktoś i przerzuci przez Kłodnicę most z papieru”. Górny Śląsk jako mit i utopia w twórczości Horsta BienkaAbstrakt: Horst Bienek był osobą bardzo znaną, wpływową i niezwykle cenioną w środowisku literackim RFN. Jest też autorem szczególnie ważnym dla literatury śląskiej ze względu na jego rolę w wewnątrzniemieckim i niemiecko-polskim dyskursie o ojczyźnie, pamięci i tożsamości. W moim tekście pokazuję strategie poetologiczne i „metodykę”, którą posługiwał się gliwicki pisarz, tworząc swoje mityczne wyobrażenia o Śląsku i (co jest nierozerwalne w przypadku jego twórczości) równocześnie o sobie samym.Słowa kluczowe: historia literatury, literatura niemiecka, literatura śląska, Horst Bienek, utopia

Bernard Horst - The connections between life and work
No full textThis thesis focuses on Bernard Horst, who is introduced, based on the historical background of the period in which he lived as well as literary reviews and the interpretation of his selected novels. The thesis aims to provide a complex overview of findings about this writer and should also - using overviews of the history of the Czech literature and literary dictionaries - partially answer the following question: In what light can the personality of a marginal author address a contemporary reader, through which perspective can this author be seen and, most importantly, how this author can be discussed using the wider literary context
Pherecardites Horst 1912
No full textGenus <i>Pherecardites</i> Horst, 1912 <p> <i>Pherecardites</i> Horst, 1912: 33.</p> <p> <i>Branchamphinome</i> Hartman, 1967: 42 <b>n. syn.</b></p> <p> TYPE SPECIES. — <i>Pherecardites parva</i> Horst, 1912, by monotypy.</p> <p> GENDER. — Feminine, after the epithet originally proposed for the type species, <i>parva</i>; Brown (1954: 590) indicates <i>parvus</i> is a Latin masculine adjective, meaning little or small (<i>parva</i> feminine, <i>parvum</i> neuter (see below).</p> <p>DIAGNOSIS. — Amphinominae with chaetiger 1 dorsally incomplete. Caruncle with a median ridge and separate, diverging lateral lobes. Branchiae from chaetiger 1. Neurochaetae spurred, with denticles along inner side.</p> <p>REMARKS</p> <p> <i>Pherecardites</i> Horst, 1912 was described without an illustration of the anterior end. Fauchald (1977) included <i>Pherecardites</i> Horst, 1912 in his key to all genera; however, Fauchald regarded the body shape of <i>Branchamphinome</i> as oval, whereas for <i>Pherecardites</i> it was assumed as rectangular. Nevertheless, Hartman (1967: 43) indicated the body shape of the type species, <i>B. antarctica</i> Hartman, 1967 changes during development: “Smaller individuals resemble the short <i>Chloeia</i> whereas longer ones are more like <i>Eurythoe</i>.” The latter has been regarded as having rectangular body.</p> <p> Consequently, <i>Pherecardites</i> and <i>Branchamphinome</i> have the same body shape and types of chaetae. What about the caruncle? Horst (1912: 33) indicated “caruncle consisting of a median axis and some lateral lamellae, directed backwards.” And in describing the type species, <i>P. parva</i>, a few lines below, he wrote: “its caruncle extends over three segments and consists of a median axis and four lateral lobes, directed backwards.” Hartman (1967: 43) indicated, in the description of the type species, <i>B. antarctica</i>, “the caruncle is tripartite, consisting of a larger, longer median lobe with lateral branches, and a pair of shorter lateral lobes […]” These two descriptions indicate a very similar shape, and after the study of type specimens, the two genera are herein regarded as synonyms.</p> <p> <i>Pherecardites</i> Horst, 1912 might be regarded as a name applied to fossils (ICZN 1999, Art. 20) and consequently, it could not “be used as the valid name of a taxon”. Further, as indicated in the example given for the same article, the genus-group name might be available if proposed “for genus-group of taxa of fossils […] and not merely to indicate fossil members of genera of extant animals”. Horst (1912) proposed <i>Pherecardites</i>, forming the name after <i>Pherecardia</i> Horst, 1886, but he was not referring to any fossil members of the same group. Consequently, it cannot be rejected as a valid name.</p> <p> There are a few instances where a similarly ending genus-group name has been regarded as valid, such as <i>Tringites</i> Cabanis <i>in</i> Gundlach, 1856 (Aves, Scolopacidae), or <i>Oceanites</i> Keyserling & Blasius, 1840 (Aves, Hydrobatidae).On the other hand, Read & Fauchald (2022) explained the etymology as: “The name of the genus is formed by the postposition of the suffix of Greek origin - <i>ites</i>, used to form adjectives, especially those to identify groups as ‘those belonging to’, to the name of the genus <i>Pherecardia</i> Horst, 1886, and seems to be used to indicate the resemblance of the new genus <i>Pherecardites</i> with <i>Pheracardia</i>.” On the other hand, the suffix - <i>ites</i> is “to be treated as masculine unless its author, when establishing the name, stated that it had another gender or treated it as such by combining it with an adjective species-group name in another gender form” (ICZN 1999, Art. 30.1.4.4). As indicated above, because Horst used the feminine (<i>parva</i>) species-group name, the gender of the genus must be treated as feminine.</p> <p> Hartman (1967) compared <i>Branchamphinome</i> with <i>Benthoscolex</i> Horst, 1912 because both have tripartite caruncle, and concluded they differ because the former has eyes, and branchiae from chaetiger 1, whereas the latter had no eyes, and branchiae from chaetiger 6. Kudenov (1993) modified the diagnosis but restricted the comparison to <i>Benthoscolex</i>. After Horst (1912) the presence of spurred neurochaetae with denticles along the inner side in <i>Pherecardites</i> resembles <i>Hermodice</i>, although some other genera also have this type of neurochaetae such as <i>Benthoscolex</i>, <i>Linopherus</i> de Quatrefages, 1866, <i>Paramphinome</i> Sars <i>in</i> Sars, 1872 and <i>Pareurythoe</i> Gustafson, 1930. Horst likely restricted the comparison to <i>Hermodice</i> and <i>Pherecardia</i> because they also have complex caruncle, as opposed to those present in the other genera. <i>Benthoscolex</i>, however, has a caruncle with three longitudinal lobes directed posteriorly, but they rise from the same point, not from a single median ridge, as is the case in <i>Pherecardites</i>.</p> <p> As currently redefined, <i>Pherecardites</i> Horst, 1912 includes <i>Branchamphinome</i> Hartman, 1967. Consequently, the species described in the latter genus must be newly combined such that <i>Pherecardites</i> includes <i>P. antarctica</i> (Hartman, 1967) n. comb., <i>P. islandica</i> (Detinova, 1968) n. comb., <i>P. kohtsukai</i> (Jimi <i>in</i> Jimi <i>et al.</i> 2021) n. comb., <i>P. parva</i> Horst, 1912, <i>P. quinquemaculata</i> Augener, 1927, and <i>P. tropicalis</i> (Barroso, Ranauro & Kudenov, 2017) n. comb.</p> KEY TO SPECIES OF <i>PHERECARDITES</i> HORST, 1912 <p> (modified after Jimi <i>et al.</i> 2021)</p> <p>1.

COMPATIBILITY PROBLEMS IN THE DEVELOPMENT OF ALGEBRAIC MODULE SPECIFICATIONS
No full textAlgebriac theory provides a framework for the specification and design of modules and modular software systems. Research in this area has focused on the development of "horizontal" operations for building up module and interface specifications. Our previous work also introduced the notion of vertical development steps, where abstract specifications are converted into a more concrete form. In this paper, we study a variety of compatibility problems between structuring operations and development steps and introduce notions of the realization of an interface specification by a module specification. These compatibility problems are studied in a categorical framework where specifications and developments steps are viewed as objects and morphisms in a "development category". We show that compatibility can be expressed as the fact that the structuring operations can be extended to partial functors and give sufficient conditions for this property
A Celebration of Independent Booksellers
No full textIndependent bookstores are treasure houres for Ideas and the Imagination, places of refuge and solace In a bytesize world of fake news. Each store is an idiosyncratic reflection of their owners' obsessions and enthusiasms; some are legends in their own right. Renowned documentary photographer Horst A. Friedrichs captures the style and mood of almost fifty bookstores across the woeld, while writer Stuart Husband tells their syories. Featuring a foreword by best-selling author Nora Krug, this book celebrates the vital role that bookstores continue to play in opening minds, freeing imaginations and spreading the word."Bookstores are treasure troves of knowledge and ideas, invaluable for the imagination, and often reflect their owners' personalities in ways internet behemoths could never re-create. In this book, photographer Horst A. Friedrichs opens the door to the world of bricks-and-mortar bookstores, showcasing their variety, quirkiness, and vitality with lavish photography. It celebrates the passion and commitment of the owners with interviews and anecdotes. Explore William Stout Books, a specialty store for architecture and art books in San Francisco, and Baldwin's Book Barn in Pennsylvania, a 5-story bookstore housed in a dairy barn open since the mid-1940s. Discover Gay's the Word, the UK's first and only dedicated LGBTQI bookshop and Livraria Lello, whose Art Deco interior is a temple to reading in the middle of Porto, Portugal. Some of the featured bookstores specialize in a certain genre, some are massive with vaulted ceilings, some are tiny and filled to the brim with books, some are in historic buildings that evoke a different time and place, and some are brand new, hightech, architect-designed spaces.
