Landscape took on a new meaning through the new science of plant geography of Alexander von Humboldt (1769-1857). In the seventeenth and eighteenth centuries, "landscape" was foremost a painterly genre. Slowly, painted landscapes came to bear on natural surroundings, but by 1800 it was still not

Full Text Available Zusammenfassung Die vorliegende Abhandlung beschäftigt sich mit einem bisher wenig beachteten Aspekt von Humboldts Amerikanischer Reise (1799─1804. Während seine Studien der Pflanzen- und Tierwelt bis heute große Aufmerksamkeit genießen, wird Humboldts Beitrag zu der Entwicklung der modernen Landwirtschaft wenig beachtet. Während seines Aufenthalts in Lima erhielt er Proben von Guano, Vogelmist von den Chincha-Inseln vor der peruanischen Küste. Einige Proben, die er von dieser Reise zurückbrachte, wurden von Wissenschaftlern in Frankreich und Deutschland untersucht. Die Analysenergebnisse zeigten außerordentlich hohe Gehalte an Pflanzennährstoffen, insbesondere Stickstoff und Phosphor. In den folgenden Jahrzehnten wurde Guano zu einem bedeutsamen Düngemittel und Auslöser eines Booms in Europa und Peru. Die Auswirkungen dieser Entwicklung sind bis heute sichtbar und werden hier unter besonderer Beachtung von Phosphor beschrieben. Abstract One aspect of Humboldt’s travel to South America (1799─1804 received little attention. The fascination of his studies of the South American flora and fauna is unbroken to the present day. Yet Humboldt’s contribution to modern agriculture remains almost unnoticed. During his stay in Lima Humboldt received samples of guano, a mixture of bird droppings from the Chincha Islands off the Peruvian coast, which he took to Europe and had analyzed by the most famous chemists in France and Germany. The results showed outstanding fertilizing effects, in particular due to the high content of nitrogen and phosphorus. The ensuing boom starting from the 1840s influenced agriculture in Europe and the economy of Peru seriously. Some aspects of this historical development may give an idea of the ensuing change not only in agriculture.

Der Briefwechsel zwischen Karl Kreil und Alexander von Humboldt, ein wichtiger Beitrag zur Geschichte des Erdmagnetismus

2016-11-01

Full Text Available Abstract The correspondence between Alexander von Humboldt und Karl Kreil was voluminous, it concerned earth magnetism. But only one letter has survived. This letter was written by Kreil on September 3, 1836; one day later Kreil wrote a letter to Carl Friedrich Gauss with nearly the same contents, some sentences are even literally corresponding. Four letters from Kreil to Humboldt were published in the „Annalen der Physik und Chemie“. Some letters were mentioned in the biographical literature dealing with Kreil. These letters show, that the correspondence covered at least the period until 1851 and give information about the intensive relationship between the two scientists. A further interesting source is the library of Humboldt which unfortunately has not survived. The catalogue mentions nine works of Kreil some of them where annotated by Humboldt. This makes it plausible that the contacts even lasted until 1856. Zusammenfassung Die Korrespondenz zwischen Alexander von Humboldt und Karl Kreil war umfangreich und betraf den Erdmagnetismus. Aber heute ist nur noch ein einziger Brief im Original bekannt. Dieser Brief, den Kreil am 3. September 1836 Alexander von Humboldt zukommen ließ, stimmt inhaltlich und teilweise wortwörtlich mit dem Brief überein, den Kreil nur einen Tag später, am 4. September 1836, an Carl Friedrich Gauß schickte. Vier Briefe von Kreil an Humboldt wurden in den „Annalen der Physik und Chemie“ publiziert, eine nicht allzu große Anzahl weiterer Briefe an Humboldt wurde in der biographischen Literatur über Kreil und in Briefen Kreils an Koller und Gauß erwähnt. Aber nicht nur die lückenhafte und bruchstückhaft bekannte Korrespondenz zwischen Humboldt und Kreil, die bis 1851 reicht, gibt Aufschluss über die Beziehungen, sondern von besonderer Bedeutung ist des Weiteren der Bestand an Kreiliana in der Bibliothek Humboldts. Es handelt sich um neun Werke Kreils, das letzte aus dem Jahr 1856. Nachweisbare

2009-01-01

This study presents an in-depth analysis of Alexander von Humboldt's descriptions and critical comments on the colonial society of the different regions he visited during his well-known expedition through the Americas (1799-1804). The criticisms of colonialism that he expressed, reflecting his personal convictions, have already been the focal point of many studies, but Humboldt also was able to offer a more differentiated assessment through comparisons of regional and local traditions and developments. This essay focuses on his personal diaries, which offer many interesting comments on colonial societies. These considerations and impressions made during the expedition are of particular scholarly value since they were not subject to censorship of any kind.

Alexander von Humboldt und die transnationale Wissenschaftskommunikation im 19. Jahrhundert

Directory of Open Access Journals (Sweden)

Ulrich Päßler

2008-10-01

Full Text Available Article in german, abstracts in english and frenchAlexander von Humboldt has been labelled a “scientific cosmopolitan”. Through his vast correspondence and a network of personal contacts, he upheld a form of scientific exchange that was characteristic of the eighteenth-century “republic of letters”.This article examines how Humboldt adapted this cosmopolitan tradition of communication to a nineteenth century scientific culture that was largely institutionalized and was becoming increasingly nationalized. Humboldt quite successfully fostered scientific exchange between Berlin and Paris after 1830 and, on various occasions between the 1830s and 1850s, readily advocated international large-scale projects. These examples demonstrate that Humboldt observed the development of nationally defined scientific cultures and the opening of the sciences towards the public realm. Moreover, they indicate how he was able to make use of these developments as he promoted the sciences in Prussia. In scientific controversies within the Parisian scientific community, Humboldt was involuntarily assigned the role of a “neutral” foreign arbitrator. Thus, the development of nineteenth century sciences also jeopardized Humboldt’s unique position as an independent “homme des lettres”.

Full Text Available Zusammenfassung Dieser Artikel untersucht das Verhältnis zwischen den revolutionären technologischen Neuerungen des 19. Jahrhunderts und dem Leben und Wirken Alexander von Humboldts (1769-1859. Dabei wird gefragt, wie Humboldt versuchte, die neuen und sprichwörtlich bahnbrechenden Kommunikations- und Transporttechnologien seiner Zeit zu nutzen, um den amerikanischen Kontinent in globale kommerzielle und kulturelle Austauschprozesse zu integrieren. Jüngere Forschungen zu Humboldts amerikanischer Expedition (1799-1804 haben behauptet, dass seine Beschreibungen Südamerikas den Kontinent für zahlreiche „transformative interventions“ (Pratt von Seiten europäischer Kapitalisten und Investoren zugänglich gemacht hätten. Diese Studien haben jedoch nicht analysiert, aus welchen Motiven heraus Humboldt diese Eingriffe in die Natur unterstützte. Darüber hinaus wurde nicht der zentralen Frage nachgegangen, welche Rolle diese Projekte in Humboldts eigener Auffassung über die Kräfte des gesellschaftlichen Fortschritts gespielt haben. Um Humboldts Unterstützung für tiefgreifende Eingriffe in die Natur Amerikas nachvollziehen zu können, analysiert dieser Artikel zunächst, welche Rolle der „Geodeterminismus“ und die Fortschrittstheorien der Aufklärung in seinem Verständnis von zivilisatorischer Entwicklung spielten. Dabei sollen solche Beispiele menschlicher Interventionen in die Natur Amerikas untersucht werden, die Humboldt selbst aktiv förderte – nicht zuletzt, da sie geeignet schienen, „natürliche“ Barrieren für gesellschaftliche Austauschprozesse zu beseitigen. Dies waren vor allem die Nutzung von Dampfschiffen, elektrischer Telegrafie, Eisenbahnen und großangelegten Kanalprojekten, deren gebündelte Effekte zu einer signifikanten Beschleunigung von Welthandel und Kommunikationsprozessen führten.

Full Text Available From the very first landing in a bounteous tropical world, European wonderment in the face of so many marvels naturally possessed a dimension that strived for knowledge and tried to conjoin a new world with old and antiquarian knowledge in a very reductionist fashion. Is Alexander von Humboldt therefore merely a new, a “second Columbus,” as he was so often described in the further course of the history of his reception? Does he simply repeat the gestures and res gestae for which the great discoverers had already set the example and in a way even predetermined? Are Humboldt and Bonpland thus caught in the trap of the perception of the other in occidental culture that enters the gray area of colonial expansion and an imperial(ist view?

Bis kurz vor der Stadt Cajamarca im heutigen Peru schrieb Montúfar ein relativ unbekanntes Tagebuch zur Reise. Nach einem kurzen Ausflug in das Leben von Humboldts Begleiter steht im Zentrum der weiteren Ausführungen die Frage, ob sein Tagebuch ein anderes Licht auf Humboldt und speziell auf den Aufstiegsversuch wirft.

After a brief excursion into the life of Humboldt’s companion, the question is considered whether his diary sheds a different light on Humboldt and specifically on the mountain climb. That amounts to a comparison of the diaries of the two travel companions and to an attempt to explain the apparent contradictions.ResumenCuando Alexander von Humboldt salió de Quito en junio de 1802 para continuar con el resto de su viaje de exploración por la América Latina, fue acompañado por Carlos Montúfar además de Aimé Bonpland hasta que volvieron a Europa.

Full Text Available Alexander von Humboldt, a German scientist and explorer of the 19th century, viewed the natural world holistically and described the harmony of nature among the diversity of the physical world as a conjoining between all physical disciplines. He noted in his diary: "Everything is interconnectedness." The main feature of Humboldt's pioneering work was later named "Humboldtian science", meaning the accurate study of interconnected real phenomena in order to find a definite law and a dynamic cause. Following Humboldt's idea of nature, an Internet edition of his works must preserve the author's original intention, retain an awareness of all relevant works, and still adhere to the requirements of scholarly edition. At the present time, however, the highly unconventional form of his publications has undermined the awareness and a comprehensive study of Humboldt's works. Digital libraries should supply dynamic links to sources, maps, images, graphs and relevant texts. New forms of interaction and synthesis between humanistic texts and scientific observation need to be created. Information technology is the only way to do justice to the broad range of visions, descriptions and the idea of nature of Humboldt's legacy. It finally leads to virtual research environments as an adequate concept to redesign our digital archives, not only for Humboldt's documents, but for all interconnected data.

Two years later, he became the first Harvard Professor of the French and Spanish Languages and Literatures. When Ticknor visited Europe in 1836 and 1856, Humboldt was his guide in the Prussian Capital. Both, Humboldt and Ticknor were mediators between the Old World and the New Continent at a time when nationalism was fashionable both in literature and in politics. Humboldt and Ticknor did not agree on all political questions. However, their respect for each other helped them avoid controversial topics in their correspondence, and possibly in their conversations. With their ability to rank the things they had in common higher than their differences they were able to maintain a fruitful transatlantic dialogue over forty years.

Full Text Available Alexander von Humboldt's expedition from 1799 till 1804 to the "equinoctial regions of the new world" led through Venezuela, Cuba, Colombia, Ecuador, Peru, and Mexico. In Europe an increased knowledge of the "New World" was connected with the privately funded journey, which served purely scientific purposes and had nothing to do with the exploration and exploitation of natural resources. Besides the research results, which were based on new measuring methods and the quantitative ascertainment of scientific basics, the journey also made possible detailed descriptions in matters of regional studies including social, socio-economic, political, and economic-geographic circumstances, which were based on empirical field studies. The expedition took place shortly before the political change in Latin America. Humboldt, who still experienced the feudal character of global economy based on slave labor in the colonies, vehemently criticized this economic structure - although he was a noble - and its unbearable social conditions. This is the reason why Humboldt is still admired in Latin America till this day. In Europe the scientific insights of his journey to the tropics and his innovative impulses in geog raphy as well as in many other disciplines brought him fame and lasting recognition as a universal scholar, who had crucial influence on the development of the sciences during the first half of the 19th century.A expedição científica de Alexander von Humboldt de 1799 a 1804 pela região equinocial do novo mundo foi realizada através dos países Venezuela, Cuba, Colômbia, Equador, Peru e México.

Alexander von Humboldt and British artists: the Oriental taste

Garrido, Elisa

2013-12-01

Full Text Available Humboldtian landscape is the best result of a close relationship between artists and scientists in the context of the Enlightenment. Many artists inspired Humboldt to develop his concept of landscape as the best way of representing Nature, but some British artists in particular were a strong reference for him. Thomas Daniell and William Hodges had travelled to Asia creating a particular imagery, which inspired the desire to travel and the feeling of the exotic taste in Humboldt. Around Humboldt, mainly two types of artists have been studied: on the one hand, painter travellers who received direct instructions from Humboldt after his experience in America, and on the other, artists who started their trips by themselves after reading his works. However, this paper is focused on the links between Humboldt and these British painters of the Orient, whom he met on a European tour with Georg Forster, before making his trip to America.El paisaje teorizado por Humboldt es el resultado de una estrecha relación entre artistas y científicos, en el contexto de la Ilustración. Muchos artistas inspiraron a Humboldt a desarrollar su concepto del paisaje como la mejor forma de representar la naturaleza pero particularmente, algunos artistas británicos supusieron una fuerte referencia para él. Principalmente, alrededor de Humboldt se han estudiado dos tipos de artistas: por una parte, los pintores viajeros que recibieron instrucciones directas de Humboldt tras su experiencia en América y por otra, los artistas que iniciaron sus viajes por iniciativa propia tras haber leído los sus trabajos. Sin embargo, este texto se centra en las relaciones entre Humboldt y los pintores británicos de Oriente, a quienes él conoció en su viaje europeo junto a Georg Forster, antes de realizar su viaje americano.

Full Text Available WILHELM VON HUMBOLDTS ANSICHT VON DER SPRACHE UND DIE FRAGE DER SPRACHENTSTEHUNG Zusammenfassung 1. Nach W. von Humboldt verfügen alle Sprachen über die gleichen Möglichkeiten. Es gibt keine Zwischenstufe zwischen Sprache und Nicht-Sprache. 2. Daraus folgt, daß Menschensprache sich nicht allmählich entwickelt haben kann. Sprechenkönnen ist eine plötzliche Entdeckung. 3. Der Unterschied zwischen nichtsprachlicher Kommunikation und Menschenspra­che ergibt sich aus der Reflexionsfähigkeit des Menschen. 4. Die Ursache der Sprachentstehung kann nicht die Notwendigkeit gegenseitiger Hilfeleistung und auch keine andere Notsituation gewesen sein. In der Bedrängnis ver­liert der Mensch im Gegenteil die Sprache. 5. Reflexion setzt das Ausklinken aus der Synchronie einer gegebenen Situation vo­raus. Vergangenes wird festgehalten, Zukünftiges imaginiert. Das ist zunächst eine Ent­deckung, ein Spiel, wie alle kulturellen Errungenschaften. 6. Die akustischen Elemente der tierischen Kommunikation beziehen sich stets auf das Hier und Jetzt. Nach dem Erringen der Möglichkeit der Reflexion können sie aus dieser Bindung gelöst werden. 7. Deshald gibt es nur in der Menschensprache ein Zeigfeld, Wörter, die zur Raum- und Zeitorientierung dienen. In Keiner „Tiersprache“ gibt es Zeichen für „dort“ oder „gestern“. 8. Zugleich mit der Möglichkeit, sich aus der Situation zu lösen, erwirbt der Mensch die Zeigegebärde, die dem Tier verschlossen ist. Die Gedanken 6. –8. finden sich nicht bei Humboldt.

Full Text Available Zusammenfassung Alexander von Humboldt hat sich in jungen Jahren mit galvanischen Experimenten beschäftigt und die Resultate in einem umfassenden, zweibändigen Werk publiziert. Dabei zeigte er nicht nur, dass er als Experimentator und Teil der wissenschaftlichen Gemeinschaft fähig war, sich mit einem so neuen und komplexen Phänomen zu beschäftigen. Es lässt sich auch erkennen, dass er bereits in dieser frühen Schrift versuchte, das umfangreiche Wissen dem Leser zugänglich zu machen. Der Artikel betrachtet Humboldts Galvanismusschrift Versuche über die gereizte Muskel- und Nervenfaser (1797–1798 und untersucht einige Elemente wie Anhänge und Schreibstil, die Humboldt nutzte, um die umfangreichen Informationen zu ordnen und dem Leser so neben den Big Data seiner Erkenntnisse auch passende Suchfunktionen zur Verfügung zu stellen, die eine gezielte Nutzung überhaupt ermöglichen.  Abstract In the early stages of his scientific career, Alexander von Humboldt took an interest in experiments in galvanism. He publicised the results in a two-volume work under the title Versuche über die gereizte Muskel- und Nervenfaser (Experiments on the Stimulated Muscle and Nerve Fibre in 1797 and 1798. In this treatise, he presented himself as competent experimenter and member of the scientific community, but also demonstrated that he was capable of researching new and complex phenomena. These volumes also provide insight into his early attempts to facilitate the readers’ access to the extensive information he had compiled. This article analyses some aspects of Humboldt’s efforts to arrange his vast numbers of observations and theories, for example by means of appendices and narrative style, which he used not only to present the resulting big data collected during his research, but also to make it possible for the reader to organise and utilise this data.   Resumen A temprana edad Alexander von Humboldt se dedicó a galvanismo.

Full Text Available Article in English, Abstracts in Spanish, German and English.Stephen Jay Gould wrote recently that “when Church began to paint his great canvases, Alexander von Humboldt may well have been the world’s most famous and influential intellectual.” Humboldt’s influence in the case of the landscape artist Church is especially interesting. If we examine the precise relationship between the German explorer and his American admirer, we gain an insight into how Humboldt transformed Church’s life and signaled a new phase in the career of the artist. Church retraced Humboldt’s travels in Ecuador and in Mexico. If we compare the texts available to Church and the comparison of Church’s paintings and the texts and images of Humboldt’s works we can arrive at new perspectives on Humboldt’s extraordinary influence on American landscape painting in the nineteenth century.

Un estudio del léxico empleado por Humboldt en las descripciones de la naturaleza revela, sin embargo, el predominio del lenguaje estrictamente científico e intersubjetivo sobre el subjetivo. La presencia de rasgos semánticos "románticos" no es, empero, meramente ornamental, sino que cumple una función estética que, en la percepción humboldtiana de la naturaleza, es un complemento subjetivo indispensable dentro de su imagen holística del mundo.

Full Text Available RésuméA la charnière du XVIIIème et du XIXème siècle, Alexander von Humboldt réalise une série de voyages scientifiques et géographiques en Europe, en Amérique et en Asie. Connus en grande partie par sa très riche correspondance, ces voyages sont tous marqués par la présence et l’intervention d’acteurs du monde politique européen. Par leur soutien financier, matériel et moral, ainsi que par leur délimitation spatiale, temporelle voire thématique des objets des expéditions, ceux-ci structurent pratiquement et intellectuellement le déroulement des expéditions humboldtiennes.Aux alentours du moment 1800, la géographie se trouve alors engagée dans un mouvement de construction disciplinaire, questionnant ses objets, ses méthodes et ses pratiques. Inséré dans ce processus, le voyage constitue un enjeu identitaire fort de l’élaboration et de la définition des savoirs géographiques modernes. La participation des acteurs politiques dans les voyages interroge leur rôle d’opérateurs de la fabrique scientifique. A partir de l’exemple humboldtien, dans une optique d’histoire et d’épistémologie de la géographie, cet article propose d’engager une analyse relationnelle du couple géographie/politique.ZusammenfassungZwischen 1799 und 1829 unternahm Alexander von Humboldt eine Reihe wissenschaftlicher Reisen durch Europa, Amerika und Asien. Nicht zuletzt dank der überlieferten Korrespondenz sind die Reisen sehr gut dokumentiert: Politische Akteure spielten eine große Rolle bei der Planung und Umsetzung der Reisen.

This kind of analysis needs to look into two topics: firstly, the aspects of his personality, his life, his work and his ideas mentioned or emphasized in publications published in those years and secondly, the facets that are not shown; both aspects will form the image that the authors intended to project.In both cases this essay attempts to interpret the intentions that might have been behind the «focus» used by the different publications. As part of this analysis, special importance has been given to the importance attributed to Humboldt in relation to two important events: the Spanish American colonial movement for independence and the beginning of what is nowadays called «modernity».This phase of Spanish History coincides with a changing and complex political-social context, which explains the need to consider not only the moderate press published in Spain under absolutist censorship, but also to include the liberal press of the opposition leaders exiled in London, in order to be able to see the different perception that these papers offered of Alexander von Humboldt.

Humboldt was elected as a chimiste célèbre, but as a member of the Academy he did not work as a chemist. When Humboldt proposed in 1837 to classify the members of each class in special fields, he chose for himself the field of "mineralogy-geology".

Alexander von Humboldt: galvanism, animal electricity, and self-experimentation part 2: the electric eel, animal electricity, and later years.

Finger, Stanley; Piccolino, Marco; Stahnisch, Frank W

2013-01-01

After extensive experimentation during the 1790s, Alexander von Humboldt remained skeptical about "animal electricity" (and metallic electricity), writing instead about an ill-defined galvanic force. With his worldview and wishing to learn more, he studied electric eels in South America just as the new century began, again using his body as a scientific instrument in many of his experiments. As had been the case in the past and for many of the same reasons, some of his findings with the electric eel (and soon after, Italian torpedoes) seemed to argue against biological electricity. But he no longer used galvanic terminology when describing his electric fish experiments. The fact that he now wrote about animal electricity rather than a different "galvanic" force owed much to Alessandro Volta, who had come forth with his "pile" (battery) for multipling the physical and perceptable effects of otherwise weak electricity in 1800, while Humboldt was deep in South America. Humboldt probably read about and saw voltaic batteries in the United States in 1804, but the time he spent with Volta in 1805 was probably more significant in his conversion from a galvanic to an electrical framework for understanding nerve and muscle physiology. Although he did not continue his animal electricity research program after this time, Humboldt retained his worldview of a unified nature and continued to believe in intrinsic animal electricity. He also served as a patron to some of the most important figures in the new field of electrophysiology (e.g., Hermann Helmholtz and Emil du Bois-Reymond), helping to take the research that he had participated in to the next level.

During the 1790s, Alexander von Humboldt (1769-1859), who showed an early interest in many facets of natural philosophy and natural history, delved into the controversial subject of galvanism and animal electricity, hoping to shed light on the basic nature of the nerve force. He was motivated by his broad worldview, the experiments of Luigi Galvani, who favored animal electricity in more than a few specialized fishes, and the thinking of Alessandro Volta, who accepted specialized fish electricity but was not willing to generalize to other animals, thinking Galvani's frog experiments flawed by his use of metals. Differing from many German Naturphilosophen, who shunned "violent" experiments, the newest instruments, and detailed measurement, Humboldt conducted thousands of galvanic experiments on animals and animal parts, as well as many on his own body, some of which caused him great pain. He interpreted his results as supporting some but not all of the claims made by both Galvani and Volta. Notably, because of certain negative findings and phenomenological differences, he remained skeptical about the intrinsic animal force being qualitatively identical to true electricity. Hence, he referred to a "galvanic force," not animal electricity, in his letters and publications, a theoretical position he would abandon with Volta's help early in the new century.

Thus, an attempt is made to answer the question why Humboldt liked to call himself "the old man from the mountains", and whether or not he found it appropriate to be called "Aristotle of our age."

Full Text Available Zusammenfassung In Gemälden, die den späten Alexander von Humboldt zeigen, finden sich bildlich verdichtete Zeichen seines wissenschaftlichen Lebens. So erinnert das Bild des von Humboldt nicht ganz bestiegenen Chimborazo an die epistemische Funktion des Unabgeschlossenen in seiner Arbeit, während Karte, Globus und die charakteristische Körperhaltung auf die zentrale Bedeutung der Bewegung und auf das „Schreiben im Angesicht der Dinge“ verweisen. Auffällig ist die Präsenz des Schreibmaterials in den Bildern, das als Verweis auf die lebenslange Bedeutung der Amerikanischen Reisetagebücher verstanden werden kann. In diesen kommen wiederum die zentralen Momente der Humboldtian Science zum Ausdruck. Der Charakter des work in progress und die konsequente Relationalität der Darstellung zeigen die epistemologischen Konstanten dieser Wissenschaft genauso an wie die in der Handschrift erkennbare Dimension der Körper-Leiblichkeit. Resumen En las pinturas que retratan al erúdito Alexander von Humboldt encontramos densos signos visuales las cuales simbolizan su vida científica. La imagen del Chimborazo, cuya cima Humboldt no había alcanzado, recuerda la función epistémica de lo inacabado en su obra, mientras que la carta, el globo y su postura típica remiten al central significado del movimiento y al “escribir de cara a las cosas”. La presencia de sus objetos de escritura en las imagenes llama la atención, ya que se puede entender como referencia al significado de los diarios del viaje americano escritos durante toda la vida. En aquellos se ponen de manifiesto los momentos centrales del Humboldtian Science. El carácter del work in progress y la relacionalidad consecuente de la representación muestran las constantes epistemológicas de esta ciencia así como la dimensión de lo corporal en los manuscritos.

Full Text Available In dieser Untersuchung werden beispielhaft die Lebenswege und Karrieren von Berliner Geowissenschaftlerinnen im Zeitraum von 1906 bis 1945 nachgezeichnet und analysiert. Ähnlich wie an anderen deutschen bzw. westlichen Universitäten, aber im Gegensatz zu Russland, begann die Tätigkeit von Frauen in den Geowissenschaften spät, und das Fach wurde auch relativ selten gewählt, hauptsächlich wegen der zu geringen Berufschancen. Aber die besondere Situation in Berlin mit mehreren sich ergänzenden Institutionen und dem daraus resultierenden breiten Spektrum an geowissenschaftlichen Disziplinen, sowie ausgezeichneten Professoren, ließ dennoch Raum für eine Ausbildung in diesem Bereich und erlaubte, wenn auch in bescheidenem Maße, eine gewisse Karrieremöglichkeit. Während der hier untersuchten 40 Jahre haben weniger als 20 Frauen in den Geowissenschaften und benachbarten Gebieten promoviert. Mehrere dieser Frauen blieben in dem von ihnen gewählten Fach weiterhin aktiv und wurden erfolgreich. Zwei Frauen gelang eine akademische Karriere — eine als Universitätsprofessorin, die auch Schülerinnen hatte. Andere arbeiteten an staatlichen Institutionen, wie z. B. dem Geologischen Landesamt. Wenige Frauen blieben nach ihrer Verheiratung beruflich aktiv, wenn auch nicht offiziell angestellt, sondern als Ehefrauen. Andere arbeiteten als "Ersatz" für die im Kriege stehenden Männer. Einige waren aus persönlichen und politischen Gründen, insbesondere während der NS-Zeit, gezwungen, die Geowissenschaften zu verlassen, konnten aber teilweise auf anderen Gebieten erfolgreich arbeiten. This paper documents the lives and careers of women geoscientists at the Berlin Friedrich-Wilhelms-University from 1906 through 1945. Traditionally, in Germany, women had difficulties to be accepted in geosciences (except for geography/geology teachers, because of strong links between geology and mining, a field dominated clearly by men.

Full Text Available Dans le septième et dernier tableau de La Tentation de saint Antoine de 1874, la fin célèbre est mise en contexte par une description longue et détaillée qui n’a jamais attiré l’attention critique qu’elle mérite. Cet article analyse l’importance de ce panorama du monde naturel sous la forme d’une exploration intertextuelle des passages du Cosmos d’Alexandre de Humboldt. Que Flaubert signale ses lectures de l’œuvre de Humboldt dans sa Correspondance de 1860 suggère des liens très riches entre Le Cosmos – que Humboldt désigne comme « l’œuvre de ma vie » – et la Tentation de saint Antoine définitive que Flaubert retravaillait au même moment. Cette relecture de La Tentation à travers la perspective de Humboldt souligne la place importante du Cosmos parmi les découvertes et les textes scientifiques contemporains de Flaubert, et la manière dont ceux-ci informent la vision de la vie scientifique et religieuse de son protagoniste, Antoine.In the seventh and final tableau of the Tentation de Saint Antoine of 1874, the famous finale is set in the context of a long, detailed description which has not attracted the critical attention it deserves. This article focuses on the importance of this panorama of the natural world as an intertextual exploration of passages from Kosmos by Alexander von Humboldt. The fact that Flaubert’s Correspondance of 1860 mentions his reading of Humboldt’s works suggests rich lines of investigation between Kosmos – which Humboldt calls the « work of all of life » and the final Tentation de Saint Antoine,which Flaubert was reworking at the same moment. This re-reading of the Tentation through the optic of Humboldt underscores the pivotal position of Kosmos amid the scientific discoveries and texts contemporary to Flaubert, and how these inform the vision of life of his protagonist, Antoine, as scientific and religious.

Full Text Available Articel in German, Abstracts in English and German.For the greater part of his life, Alexander von Humboldt was interested in colour phenomena which he observed in nature. These observations led him to do research into phenomena such as the blue colour of the sky, enigmatic dust and hail, and the colour of plants. Humboldt corresponded with many scientists about the connection between sunlight and the creation of colours, about coloured shadows, the Blue Cave in Capri, the colour of stars, plants etc. Claude-Louis Berthollet developed a model for the composition of a blue colour (Indigo, a technology which was of great importance to the textile industry.The present paper focuses on Humboldt’s interest in the blue colour of the sky, which he shared with artists, writers and scientists like Johann Wolfgang von Goethe, Christian Gottfried Lichtenberg, Caspar David Friedrich and Horace Bénédict de Saussure. During his travels in South America, Humboldt used Saussure’s cyanometer to determine the intensity of the blue colour of the sky. Later he corresponded about this instrument with his friend François Arago who had invented a cyanometer based on chromatic polarisation. While Humboldt was working on his “Cosmos”, Arago explained to his friend the latest results in physics, especially in polarography. Towards the end of his life, Humboldt corresponded with the painter J. G. Schall and admitted that he had somewhat lost his interest in the physical explanation of the blue colour of the sky.

Full Text Available British author Helen Maria Williams (1759-1827 was a well-known figure in the eighteenth century literary circles, whose work was praised by Elizabeth Montagu, Samuel Johnson, Dorothy and William Wordsworth, Mary Wollstonecraft, Hester Piozzi or Alexander von Humboldt.  In her early poems  Edwin and Eltruda (1782, An Ode to the Peace (1783 and Peru (1784, Williams starts to reveal her political tendencies by appealing to strong empathic feelings as a key to social and political transformation. As a result of her interest in politics, she travelled to France in 1790 and published her most acclaimed work Letters from France (1790. However, the rest of her production has received little critical attention by modern scholars, who have overlooked her involvement in translation. Williams’ only extant novel, Julia (1790 is in fact a creative translation of Rousseau’s Julie ou La Nouvelle Héloïse (1761, in which Williams includes poems that evidence her interest in revolutionary politics. Four years later, she translated Bernardin de Saint Pierre’s Paul et Virginie, while she was imprisoned in Paris. While translating novels was regarded as a respectable exercise for women writers, Williams challenges gender assumptions by translating Researches (1814 and the seven volumes of Personal Narrative (1814-1829, which had been produced by one of the most influential eighteenth century scientists, Alexander von Humboldt. This article interrogates how Williams makes use of translation to access areas of knowledge traditionally restricted to men, such as philosophy, politics and science. For this purpose, I will focus on her translations of the work of two leading intellectual figures of the eighteenth century,  Rousseau and Von Humboldt.

Questions like ‘What is the university?’ ‘What is its role?’ are typical philosophical questions. They are characteristically huge questions. But they are queries which engage us continuously. They are important questions. They were asked by a long line of distinguished thinkers who gave variant, yet overlapping, answers: universities should be governed by “an idea of reason” (Immanuel Kant); they serve the culture of the nation-state (Wilhelm von Humboldt); they exist to “civilise gentlemen”...

Full Text Available Abstract In this paper we discuss how Alexander von Humboldt conceived a past to New Spain in his Political Essay on New Spain (1811 and how this text was, in turn, appropriated by the Mexican historiography during the 19th century. In order to do so, we analyze how the Prussian drew from American sources, particularly from the text of the Jesuit Francisco Javier Clavijero, written shortly before. We also study Humboldt’s conceptions of text and of history, highlighting the place of the indigenous in the composition of his reasoning. Finally, we give examples of how the Mexican nationalist historiography read and reinterpreted the Political Essay. Resumen En este artículo se discute cómo Alexander von Humboldt concibió un pasado a la Nueva España en su Ensayo político sobre el reino de la Nueva España (1811 y cómo este texto, a su vez, fue apropiado por la historiografía mexicana durante el siglo XIX.

La fabrique du savoir Essai sur les carnets de voyage d'Alexander von Humboldt

Full Text Available Article in French, Abstract in English.Whilst the notebook belongs to the imagery of the enlightened scientist's persona (an auxiliary tool kept by his side to be hastily scribbled with data, when at the bench or in the field, it has been given little attention by historians of science, who are used to consider its manuscript pages as a documentary resource to complement the printed text, but rarely take the notebook as a material and cultural object by itself, the history and epistemology of which is to be explored. Only recently have new trends in the historiography, by historians of printed books and reading practices, and by social and cultural historians of knowledge, called for a fresh look and opened the way for new approaches. Taking Alexander von Humboldt as a paramount example, who expressly devoted his life to "observing and recording" the world, pen in hand, this paper explores the note-taking practices at work in his travel diaries and notebooks from the perspective of the history of scientific observation and cognitive practices. Four themes are successively considered : the question of method and apprenticeship ; the timing of note-taking practices ; the nature and status of the data jotted down on the page ; finally, their uses in the production of scientific knowledge. In the back and forth movement between the observation of the world and the writing of science, the notebook stood as a crucial intellectual step and cognitive tool.

Full Text Available This study seeks to collect the comments and judgements that Humboldt makes about Cuba and evaluate their character. The resulting analysis and interpretation will be undertaken on two different levels: One refers to the information that can be found in his unofficial works, which means the letters Humboldt sent during or shortly after of his visits to Cuba, as well as the diaries he used during his expedition. The other is based on the official works, which include his travel description, his famous Essay on Cuba and his autobiographical text written in 1804. Constrasting these descriptions, we will compare the evaluations of this Prussian traveller elaborated in the moment he visited the island, with the works he wrote 22 years after his return to Europe.

Full Text Available Article in Spanish, Abstracts in English and German.The article “Humboldization of the Western world? The importance of the travel of Humboldt for Europa and for Latin America”, treats the empirical Prussian Scientist as a globalist (Universalgelehrten, in accordance to the conceptualization made by Ottmar Ette. Humboldt was one, if not the most important founder of Western moderne. As opposed to the well-known founders of the moderne (Descartes, Kant, Buffon, Schiller, Hegel, Marx ... etc., Alexander von Humboldt was an empirical and a global thinker. He did this in transcultural manners, sometimes already in intercultural manners. But most of times, his point of view is based in the European tradition of roman-classicist and aesthetic thinking. The article tries to demonstrate three types of knowledge in Humboldt and also, that the humboldtian universalism has important intercultural bases in the comunication with American scientists and in the American empiricism (“local knowledge”. One importance of such a conceptualization of Humboldt is shown – in negation – in the actual debates over diaspora and race in the Atlantic world (“Black Atlantic”. Humboldt knowledge of American slaveries and his absolute condemnation of slavery in his “Island of Cuba” is not present in these debates. In the second part the article demonstrates possibles manners of reading the diaries of Humboldt, by constructing “essais imaginaires” about colonialism, slavery, Peru, the Pacific ocean etc.

Full Text Available A versão do poema épico indiano Bhagavad-Gita do sânscrito para o latim, realizada por August von Schlegel, gerou controvérsia no início do século XIX, nos anos que se seguiram a 1823, quando foi publicada. O trabalho foi criticado pelo sanscritólogo francês S. A. Langlois e criteriosamente estudado por Wilhelm von Humboldt, que não lhe poupou elogios. O filósofo Georg W. F. Hegel baseou-se, por sua vez, no estudo de Humboldt, principalmente para questionar a afirmação de Humboldt e de Schlegel, de que o texto traduzido seria a única poesia antiga com autêntico conteúdo filosófico, e também para fazer algumas observações tradutológicas. Essa polêmica erudita foi enriquecida posteriormente com as opiniões de autores ingleses como H. Th. Colebrooke, também especialista em sânscrito, e Charles Wilkins, que fizera a primeira tradução da Bhagavad-Gita para a língua inglesa, em 1784. Esse debate inspiraria então as reflexões de August von Schlegel sobre tradução, que ele escreveu em 1826, ou seja, 3 anos após a sua primeira tradução da Bhagavad-Gita. Em 1846, um ano após sua morte, é publicada uma segunda versão que ele havia feito desse mesmo poema.

“Alexander von Humboldt” als Name für Forschungsschiffe vor dem Hintergrund seiner meereskundlichen Arbeiten

Full Text Available Article in German, Abstract in English. A. v. Humboldt as a Name of Research VesselsA number of special purpose vessels in the world carried or carry the name of Alexander von Humboldt, who had substantial interests in oceanography. However, most of his marine texts are scattered over his major works, and he never finished his manuscript on ocean circulation. But there is a general agreement that A. v. Humboldt was one of the pioneers of marine sciences. He made his own observations on the sailing vessels he used on his expedition to the Neotropics, mainly concerning sea surface temperatures. In 2002 there was a discussion in Germany about the name of a new research vessel which is going to be commissioned in the summer of 2004. It was suggested by the science community to take the name of „Alexander von Humboldt“ again, as the new vessel is replacing a medium-sized ship with this name operated now by the Baltic Sea Research Institute in Rostock-Warnemünde. This vessel has been in service from 1970 to 1990 for the Academy of Sciences of the former German Democratic Republic. The first German research vessel „Alexander von Humboldt“ was a fishing trawler (1939. Furthermore, Peru and Mexico operate research vessels bearing Humboldt’s name. The best known „Alexander von Humboldt“ is an ocean going sailing ship of the International Sail Training Association, based in Bremen. She is engaged in educational programmes and went the South America in 1999 following Humboldt’s route. Thus, Humboldt’s marine legacy is preserved. The proposal to use the undisputed name of this great all-round scientist for the new German vessel under construction now was not successful. A high-ranking jury decided to prefer “Maria Sibylla Merian” (1647-1717, which was suggested by a young student in a nation-wide competition to find a name. As Humboldt 100 years later, she went to South America to study plants and other fields of natural history.

En el reino de la ambivalencia. La Cuba de Alejandro de Humboldt

2001-04-01

Full Text Available Article in Spanish, Abstracts in English and German.In the Realm of Ambivalence.The Question of Cuba in Alexander von Humboldt’s American TravelogueCuba has a special role in Alexander von Humboldt’s American travel narrative: Humboldt’s experience of colonial slave economy drives his optimistic philosophy, inspired by European Enlightenment, into a crisis, and brings to surface the inherent contradictions of his discourse. This phenomenon is particularly interesting from the perspective of literary criticism: Alexander von Humboldt conceives Cuba as a poetic space, where contradictions and ambivalences coexist. Already on the boat to the island from Venezuela he creates destablizing effects of sensual perceptions. He stages his landing in Havana as a moment of oppositional impressions. Within the symbolic topography of his geographic fantasy, Cuba functions as an imaginary in-between space. And Humboldt’s philosophical and aesthetic terminology undergoes a semantic recoding in Cuba: what was once used in a philosophical and aesthetic sense, now has become charged with an economic and political meaning.

The Alexander von Humboldt Conference Series of the European Geosciences Union are a series of meetings held outside of Europe, in particular in South America, Africa or Asia, on selected topics of geosciences with a socio-economic impact for regions on these continents, jointly organised with the scientists and their institutes and the institutions of these regions. Given the increasing success of the GIFT workshops held in conjunction with the General Assemblies, since 2010 EGU has also developed a series of GIFT workshops held in conjunction with AvH conferences. Associated GIFT workshops were held in Merida, Yucatan, on the theme of Climate Change, Natural Hazards and Societies (March 2010), then in Penang, Malaysia (June 2011) on the theme of Ocean Acidification, in November 2012 in Cusco (Peru) on the theme of Natural Disasters, Global Change and the Preservation of World Heritage Sites, finally in Istanbul (March 2014) on "High Impact Natural Hazards Related to the Euro-Mediterranean Region. The next GIFT workshop is already planned for October 2015 in Adis Ababa (Ethiopia) on the theme "Water". In each case, the GIFT workshop was held on the last two days of the AvH conference and reunited 40-45 teachers from the nation where the AvH was held. Keynote speakers from AvH were speakers to the GIFT workshops which also included hands-on activities animated by sciences educators. These GIFT workshops represented the first workshops specifically aimed at teachers held in the country, and therefore represents a significant Earth Sciences contribution to secondary education in non European countries.

In the middle of the eighteenth century, Carl von Linné, Johann Christoph Gatterer, and Christian Wilhelm Büttner attempted to realize the old idea of deciphering the alphabet of the world, which Francis Bacon had raised as a general postulate of science. This article describes these attempts and their interrelations. Linné used the model of the alphabet to classify plants according to the characters of this fruiting body. Gatterer, one of the leading German historians during the Enlightenment, adopted the botanical method of classification by genus and species to classify the history of scripts. He used the forms of the alphabetic characters to measure the age of manuscripts and to map the process of history as a genealogy of culture. Gatterer collaborated closely with Büttner, the first Göttingen professor of natural history. Büttner constructed a general alphabet of languages which connected the phonetics of language with the historically known alphabets. Early on, diplomatics and ethnography combined the natural order of natural history and the cultural order of the alphabet with the attempt to register development and to document development by the evolution of forms. Based on the shared model of the alphabet and on the common necessity to classify their empirical material, natural history and the description of culture were related attempts in the middle of the eighteenth century to comprehend the alphabetically organized nature and a naturally ordered culture.

The Kaiser Wilhelm Institute for Physics is best known as the place where Werner Heisenberg worked on nuclear weapons for Hitler. Although this is essentially true, there is more to the story. At the start of World War II this institute was taken over by the German Army Ordnance to be the central, but not exclusive site for a research project into the economic and military applications of nuclear fission. The Army physicist Kurt Diebner was installed in the institute as its commissarial director. Heisenberg was affiliated with the institute as an advisor at first, and became the director in 1942. Heisenberg and his colleagues, including in particular Karl-Heinz Hoecker, Carl Friedrich von Weizsaecker, and Karl Wirtz, worked on nuclear reactors and isotope separation with the clear knowledge that these were two different paths to atomic bombs [Atombomben]. However, they were clearly ambivalent about what they were doing. New documents recently returned from Russian archives shed new light on this work and the scientists' motivations. (orig.)

Full Text Available La investigación constituye un elemento fundamental de desarrollo humano y social. Bajo esta perspectiva, supone desafíos y oportunidades particulares para los llamados países "en vías de desarrollo". Una aproximación a tales desafíos y oportunidades se desprende del análisis de dos actividades interrelacionadas: la formación de nuevos investigadores y el desarrollo de investigación con instituciones o investigadores externos a la propia institución ("investigación colaborativa". Ambas actividades son esenciales en la consolidación, ampliación y actualización de las capacidades institucionales de producción científica. Presentamos aquí las experiencias del Instituto de Medicina Tropical "Alexander von Humboldt" de la Universidad Peruana Cayetano Heredia con relación a la formación de investigadores; discutimos los cuatro elementos que consideramos clave en dicho proceso: promoción de entornos estimulantes para investigación, identificación proactiva de becarios, asesorías complementarias y consolidación de redes; y analizamos tres modelos de colaboración internacional exitosos en la formación de nuevos investigadores bajo distintas aproximaciones institucionales.Research is a main element for human and social development.

Decommissioning of the Humboldt Bay Power Plant, Unit No. 3, Docket No. 50-133, Humboldt County, California

International Nuclear Information System (INIS)

1987-04-01

Environmental impacts associated with the SAFSTOR option for decommissioning the Humboldt Bay Power Plant, Unit 3, located four miles southwest of the city of Eureka in Humboldt County, California, are assessed. Humboldt Bay Unit 3, a 65-MWe boiling water reactor, was operated commercially from August 1963 until July 1976, at which time it was shut down for seismic modifications. The facility would be stored safely for approximately 30 years. Estimated annual purchases of materials and supplies resulting from SAFSTOR activities are expected to be $20,000 (1984 dollars), and these purchases are expected to be made in Humboldt County. A fuel-handling accident would result in atmospheric radionuclide releases that are well below EPA Protective Action Guide (PAG) levels. Damage to all the stored-fuel assemblies resulting from a nonmechanistic heavy-load drop would result in atmospheric radionuclide releases that are also well below the PAG levels. There is a negligibly small likelihood that seismic loads or other mechanical loads would generate criticality among the spent fuel assemblies stored in the pool. The upper limits of potential lung, liver, and bone doses resulting from an instantaneous expulsion to the atmosphere of the entire water/radionuclide content of the spent-fuel pool are very small fractions of the PAG levels. A rupture of the spent-fuel pool or the liquid radwaste tanks would result in a total body dose to an average individual via the seafood chain that would be less than the dose from natural background levels. Doses from recreational activities in Humboldt Bay would be negligible

2017-09-01

– The project itself, as represented by Wilhelm, appears to be informed by a cultural movement towards emancipation from French culture: The character of Hamlet was interpreted as representing a role model for young Germans.– Informed by a theatrical practice based on French conventions, the manager objects to the lack of dramaturgical coherence of the Shakespeare play. As a compromise, Wilhelm composes an adapted version in which references to Wittenberg, Poland, France and England as well as several minor characters are cut, but the Hamlet scenes and speeches are retained.– Wilhelm and his friends also take account of German audiences’ preferences and capacities.

Armouring facility? Nuclear-weapon and reactor reseach at the Kaiser-Wilhelm Institute for Physics

International Nuclear Information System (INIS)

Hachtmann, R.; Walker, M.

2005-01-01

The Kaiser Wilhelm Institute for Physics is best known as the place where Werner Heisenberg worked on nuclear weapons for Hitler. Although this is essentially true, there is more to the story. At the start of World War II this institute was taken over by the German Army Ordnance to be the central, but not exclusive site for a research project into the economic and military applications of nuclear fission. The Army physicist Kurt Diebner was installed in the institute as its commissarial director. Heisenberg was affiliated with the institute as an advisor at first, and became the director in 1942. Heisenberg and his colleagues, including in particular Karl-Heinz Hoecker, Carl Friedrich von Weizsaecker, and Karl Wirtz, worked on nuclear reactors and isotope separation with the clear knowledge that these were two different paths to atomic bombs [Atombomben]. However, they were clearly ambivalent about what they were doing. New documents recently returned from Russian archives shed new light on this work and the scientists' motivations. (orig.)

The Kaiser Wilhelm Society under National Socialism

CERN Document Server

Sachse, Carola; Walker, Mark

2009-01-01

During the first part of the twentieth century, German science led the world. The most important scientific institution in Germany was the Kaiser Wilhelm Society, including institutes devoted to different fields of scientific research. These researchers were not burdened by teaching obligations and enjoyed excellent financial and material support. When the National Socialists came to power in Germany, all of German society, including science, was affected. The picture that previously dominated our understanding of science under National Socialism from the end of the Second World War to the recent past - a picture of leading Nazis ignorant and unappreciative of modern science and of scientists struggling to resist the Nazis - needs to be revised. This book surveys the history of Kaiser Wilhelm Institutes under Hitler, illustrating definitively the cooperation, if not collaboration, between scientists and National Socialists in order to further the goals of autarky, racial hygiene, war, and genocide.

How our changing research arena can inspire innovative environmental research in developing countries (Alexander von Humboldt Medal Lecture)

Science.gov (United States)

Bouma, Johan

2017-04-01

Alexander von Humboldt was a true pioneer by engagingly articulating an ecosystem-wide vision on environmental issues and research, connecting and moving beyond disciplinary boundaries. Focusing here on soil science as an important discipline within the geosciences, the work of our group has acted in the spirit of this approach by focusing on interdisciplinary systems research in different developing countries in close interaction with stakeholders, based on soil processes in a dynamic landscape context. But recent developments of internet and social media are drastically changing relations between science and society all over the world. Scientists have to continuously struggle to keep their "societal license to research". Researchers in so-called developed countries would be well advised to communicate lessons learned to scientists in developing countries allowing them to leapfrog and avoid making time- consuming mistakes adhering to yesterday's practices. Specifically, attention should be paid to: (i) more continuing interaction with stakeholders when planning and executing research. This takes time that should be allocated in research projects. ; (ii) the quality of a limited number of key papers rather than on the total number of published and cited scientific papers, when judging researchers; (iii) defining new research on the basis of proven inadequacy of existing techniques and methods, realizing that "new" is not necessarily "better" and that available research methods and procedures can solve many current environmental problems; (iv) showing the value of the scientific approach that does not articulate: "yet another opinion" but is essential to face the major environmental challenges of the 21th century. (v) demonstrate the crucial importance of interdisciplinary ecosystem research and innovation when addressing the seventeen UN Sustainable Developments Goals (SDG's) that are attractive now as a focus for the scientific effort in land-related research.

COLOMBIAN FROZEN BIODIVERSITY: 16 YEARS OF THE TISSUE COLLECTION OF THE HUMBOLDT INSTITUTE

Directory of Open Access Journals (Sweden)

2015-05-01

Full Text Available Collections of tissue samples stand as keystone sources of molecular information to construct biodiversity knowledge, and are particularly useful in megadiverse countries. In 1998 the Humboldt Institute (Instituto de Investigación de Recursos Biológicos Alexander von Humboldt began a tissue collection of Colombian biodiversity (IAvH-CT and the aim of this work is to present a diagnostic and an historical narrative for that collection, constructed by compiling information and experiences on its management as well as by organizing and curating the information of each catalogued sample. After 16 years the IAvH-CT harbors 16469 samples, which represent around 2530 species from 1289 genera, and 323 families of the Colombian biodiversity. Samples are biased toward plants and birds (84 %, but also include other animal taxa. Geographically, IAvH-CT includes samples from all Colombian departments, but there is a broad variation in their coverage. When compared with other international collections IAvH-CT fulfills several standards of sample storage and data management, but have a major weakness that is that several tissues seem to lack a vouchered specimen. Tissues housed at IAvH-CT have been included in at least 48 studies published in several scientific journals. IAvH-CT is implementing strategies to improve curatorial standards, fill-up taxonomic gaps, and to explore the potential of its samples to understand the outstanding Colombian biota in a cooperative research frame among institutions.

Preliminary results of hydrogeologic investigations Humboldt River Valley, Winnemucca, Nevada

Science.gov (United States)

Cohen, Philip M.

1964-01-01

Most of the ground water of economic importance and nearly all the ground water closely associated with the flow o# the Humboldt River in the. 40-mile reach near Winnemucca, Nev., are in unconsolidated sedimentary deposits. These deposits range in age from Pliocene to Recent and range in character from coarse poorly sorted fanglomerate to lacustrine strata of clay, silt, sand, and gravel. The most permeable deposit consists of sand and gravel of Lake Lahontan age--the so-called medial gravel unit--which is underlain and overlain by fairly impermeable silt and clay also of Lake Lahontan age. The ultimate source of nearly all the water in the study area is precpitation within the drainage basin of the Humboldt River. Much of this water reaches the study, area as flow or underflow of the Humboldt River and as underflow from other valleys tributary to the study area. Little if any flow from the tributary streams in the study area usually reaches the Humboldt River. Most of the tributary streamflow within the study area evaporates or is transpired by vegetation, but a part percolates downward through unconsolidated deposits of the alluvial fans flanking the mountains and move downgradient as ground-water underflow toward the Humboldt River. Areas that contribute significant amounts of ground-water underflow to. the valley of the Humboldt River within the study area are (1) the valley of the Humboldt River upstream from the study area, (2) the Pole Creek-Rock Creek area, (3) Paradise Valley, and (4) Grass Valley and the northwestern slope of the Sonoma Range. The total average underflow from these areas in the period 1949-61 was about 14,000-19,000 acre-feet per year. Much of this underflow discharged into the Humboldt River within the study area and constituted a large part of the base flow of the river. Streamflow in the Humboldt River increases substantially in the early spring, principally because of runoff to the river in the reaches upstream from the study area

["As we're not willing to hang and behead and not able to deport...". On Emil Kraepelin's influence on Franz von Liszt].

Science.gov (United States)

Schmidt-Recla, A; Steinberg, H

2008-03-01

Emil Kraepelin started his scientific career with a pamphlet demanding complete restructure of German penal law. It is well known that Kraepelin was a recipient of Cesare Lombroso's theses on degeneration and atavism. Therefore his demand for a correctional law completely replacing penal law is easily understood. Still undiscussed however is the question of whether Kraepelin's brochure had a decisive effect on German criminal law, especially on the so-called Marburg Program of Franz von Liszt, still viewed as the first emergence of modern criminal law and policies in Germany. Examination of this shows that despite major theoretical faults, Kraepelin came to conclusions that correspond remarkably with von Liszt's. Special focus should be directed on the psychologist Wilhelm Wundt, who criticised Kraepelin's juridical attempt in a very kind yet fundamental way, and on the relationship that existed between Kraepelin and von Liszt.

Humboldt entre a filosofia da natureza e a ciência moderna / Humboldt between the philosophy of nature and modern science

Directory of Open Access Journals (Sweden)

Thiago Brito

2015-08-01

Full Text Available This work aims to identify the influence of German thought, above all, the philosophy of nature in Humboldt's “modern science”. He brings from the philosophers the conception of the harmonious totality of nature as an organism to recognize the existence of a connection between the forces of nature and its form captured by intuition. The philosophy of nature exposes the bond between the visible world and the upper world that escapes the senses. Humboldt, however, is not only concerned with the contemplation of nature, but also seeks to measure it, bringing it closer to his eyes to understand its internal connections. The technical and scientific instruments are also an extension of his gaze and his hand. Humboldt want to combine the measurement and quantification with the enjoyment afforded by intellectual intuition in touch with the landscape. The Cosmos, therefore, is presented as a whole to be deciphered through observations and comparisons, but also through an aesthetic perception of natural phenomena.

Full Text Available The Spanish diary can surprisingly not be found in his bounded diaries from his American travels, but in a separate folder of his legacy in Berlin, where Humboldt collected material which he wanted to use for his publication about Spain. So it remained undiscovered until recently. Humboldt’s notes contain geognostic descriptions as well as his observations about climate, vegetation, electricity of the atmosphere, etc. The comparison with Humboldt’s publication of 1825 facilitates to gain insight into his scientific methods.

El diario español de Humboldt se encuentra sorprendentemente en una carpeta de su legado en Berlín, donde el mismo recopiló los materiales para su publicación sobre la meseta española en la revista Hertha, y no en sus diarios encuadernados del viaje americano. Esto explica que no se hubieran descubierto hasta hace poco tiempo. El manuscrito contiene descripciones geognósticas, observaciones sobre el clima, la vegetación, la electricidad de la atmósfera, etc. La comparación con lo publicado de Humboldt en 1825 sobre la meseta española que realizamos en las notas de esta edición facilitará al lector una aproximación a los métodos cientificos típicos de Humboldt.

MUSICOLOGY AS AN EVOLUTIONARY SYSTEM OF THE MUSICAL THINKING CATEGORIES (PROPOSED FORAMETHODOLOGICAL-HERMENEUTICS APPROACH

Directory of Open Access Journals (Sweden)

GARAZ OLEG

2015-03-01

Full Text Available The appearance of musicology as a science is due yo Guido Adler’s foundation act of 1885. The dialectical formulation of musicology as an interaction between systematic and historical disciplines were to confer it sufficien methodological force so that the newly invented science could become practicable as soon as possible. Historically being a descendant of the German historical method (Leopold von Ranke and the one contemporary with positivism (Auguste Comte, musicology affirms itself quickly as an academic discipline (begun by Wilhelm von Humboldt and takes in both sociology (Max Weber and hermeneutics (Hermann Kretzschmar as constituent disciplines. In one sense, musicology presented itself as an open conceptual system, permeable to the evolutionary changes of the thinking field and musical practices and, in a second sense, the methodology of systematic conceptual organization was oriented towards the university teaching field as an offer for pedagogical and research activities. In our text, we propose a hipothesis of approaching the conceptual system of musicology as a cosubstantional system of botn the constituent parts — the systematic and the historical ones, in such a way motivating and explaining its dialectical-evolutionary nature.

In den Vereinigten Staaten werden Lernziele und Kompetenzen geformt, um die Studenten gegenüber den vielen kulturellen Hintergründen, die in den Bildungsinstitutionen vorzutreffen sind, zu sensibilisieren.Trotzdem wird wahre Globalität, wie sie heute in den vielfältigen Diskursen und Perspektiven der Welt repräsentiert ist, immer noch in Lehrplänen und Studienarbeiten vernachlässigt. Dieser Artikel untersucht die Möglichkeiten, die sich heute im Bildungswesen durch den neuen, gemeinsam geteilten, globalen Bildungsraum anbieten, in dem die multikulturelle Studentenbevölkerung verschiedene Formen vernetzten Wissens und facettenreiche Perspektiven der Welt eine globale Plattform des Austausches bildet. Das von Alexander von Humboldt am Anfang des neunzehnten Jahrhunderts beschriebene universale Wissenschaftskonzept, beleuchtet solch einen vernetzten Ansatz an ein Wissen um die Welt, der auf heutige Bildungskonzepte und Kursdesigns einen positiven Einfluss nehmen könnte. Humboldts Schriften unterstreichen die Bedeutung der Inklusivität und des Wechselspiels zwischen Kulturen und Naturphänomenen. Indem wir Studenten mit unterschiedlichem kulturellen Hintergrundwissen dazu einladen, ihre jeweiligen Diskurse des Wissens aktiv zu repräsentieren, werden diese gegenseitig mit einander verknüpten Beziehungen des Wissens transparenter. Auf diese Weise, entsteht die Möglichkeit, heutige Lernziele mit neuen, produktiven Formen des Weltwissens zu berreichern, worin sich ein wahres Weltbürgertum, wie es sich in diesem neuen Bildungsraum des globalen Austausches hervortut, wiederspiegeln würde.

Full Text Available The current recovery of the notion of landscape as a means of comprehending the relationships between nature, society and culture in their spatiotemporal dimensions, that is, as specifi c totalities, calls for a return to its most fecund presentations, beginning with what is perhaps the most outstanding version of them all, that of Alexander von Humboldt. On this occasion we intend to make a reading in terms of landscape of Essay on the Geography of Plants and of the accompanying Physical Tableau, the one of humboldtian works less known. We believe that our study will demonstrate that Humboldt’s contribution on landscape and landscapes was to a great extent contained in the initial text of Geography of Plants; which in turn enables us to explore the fundamental relationship between landscape and the initial development of Biogeography.

Analyses of M3 data, using a custom-made method for M3 spectra continuum removal and spectral parameters calculation, reveal multiple pure crystalline plagioclase detections within the Humboldt crater central peak complex, hinting at its crustal origin. However, olivine, spinel, and glass are observed in the crater walls and rims, suggesting these minerals derive from shallower levels than the plagioclase of the central peak complex. High-calcium pyroxenes are detected in association with volcanic deposits emplaced on the crater's floor. Geologic mapping was performed, and the age of Humboldt crater's units was estimated from crater counts. Results suggest that volcanic activity within this floor-fractured crater spanned over a billion years. The felsic mineralogy of the central peak complex region, which presumably excavated deeper material, and the shallow mafic minerals (olivine and spinel) detected in Humboldt crater walls and rim are not in accordance with the general view of the structure of the lunar crust. Our observations can be explained by the presence of a mafic pluton emplaced in the anorthositic crust prior to the Humboldt-forming impact event. Alternatively, the excavation of Australe basin ejecta could explain the observed mineralogical detections. This highlights the importance of detailed combined mineralogical and geological remote sensing studies to assess the heterogeneity of the lunar crust.

Alexander von Humboldt y la comparación de las esclavitudes en las Américas

Full Text Available This article has two main aims. Both are motivated by the Humboldtian diary about Cuba in 1804, unknown until today (found by Ulrike Leitner in the Biblioteka Jagiellonska Kraków. First, the article will present the in fact discontinuous but coherent development of the Humboldtian image of slavery in Spanish America (which is culminating to some extent in the diary and builds in nuce what later will become the “Essay on the Island of Cuba”. Second, the article presents the sensation in history of science, that Humboldt starts to apply systematically main elements of scientific method of comparison on social, historical and socioeconomic themes of slavery, when he heard of the proclamation of the new state of “Haity” in Veracruz or Havana in 1804. These two findings (and the diary itself are changing profoundly our knowledge about Humboldt’s political relationship with two larger groups of the population of Spanish America (the parts of the Creole elite who were planning to found “a white republic”, following the French model and the very large group, or caste, of the “pardos” on the “Eve of the Independence Movement”.

Wilhelm Hofmeister and the foundations of plant science.

Martin, Cyrus

2017-09-11

On January 12 th 1877, the Grim Reaper visited Wilhelm Hofmeister (Figure 1) for the last time. Having recently witnessed the death of a wife, two daughters, and two sons (only two of his nine children survived him), the German botanist, perhaps succumbing to the weight of his own grief, suffered a series of strokes and then promptly died at the age of 52 in Lindenau, Germany. He has since faded into the dusty annals of 19 th century botany, his contributions to our knowledge about plants, how they come into being, develop and interact with their environment, mostly forgotten. In an ode to Hofmeister marking 100 years since his birth, Douglas Haughton Campbell of Stanford University, referring to Hofmeister's studies in comparative morphology, wrote, "…there is no question that Hofmeister's work will remain as probably the most brilliant contribution ever made to this fundamental department of botany" [1]. And in an essay published in Plant Physiology, Donald Kaplan and Todd Cooke went further still, writing, "Frederich Wilhelm Benedikt Hofmeister stands as one of the most remarkable figures in the history of botany and one who made fundamental contributions to all areas of plant biology" [2]. If that wasn't enough, Kaplan and Cooke added "In terms of native genius, he is certainly the peer of both Darwin and Mendel and may have even exceeded them in the breadth and depth of his talents."

Full Text Available Eduard Spranger, Herman Nohl y Wilhelm Flitner son herederos directos del espiritualismo, el psicologismo y el historicismo de Wilhelm Dilthey, elaborando, a partir de él, pedagogías de marcado carácter cultural. Todos ellos se propusieron reelaborar el cuerpo epistemológico de la pedagogía, siguiendo, para ello, la tradición racionalista, de corte neokantiano, propia del momento (primera mitad del siglo XX. Para Spranger la ciencia de la educación se reducirá a una pedagogía de la comprensión hermenéutica; su misión consistirá en tomar una realidad cultural históricamente heredada y someterla a conceptos ordenadores que permitan adoptar posicionamientos valorativos y normativos de actuación. Nohl, por su parte, entenderá la pedagogía como una teoría de la educación que deberá siempre contextualizarse históricamente por lo que jamás podrá tener validez general. Por último, Flitner considerará la ciencia pedagógica como un filosofar dentro de la circunstancia histórica, es decir, una estética de la educación.

Do We Know More About Whorf?

Yanlong Wang

2016-01-01

Full Text Available The idea that different languages foster different world views in their speakers is part of a tradition popularized by Wilhelm von Humboldt in the 18th century long before it became associated with Whorf.  In this long process, another two American linguists, Boas and Sapir, are also well-known for their great contributions to this notion.  This paper tries to trace the linguistic relativity back to its origin and contextualize its diachronic developments from Europe to America.  It is true, however, that it was Benjamin Lee Whorf, the chemical engineer and fire-insurance by profession and the linguist by avocation, who had undertaken extensive research into the language Hopi during 1932-1935 and Maya in late 1930s, and it was he who went further in indicating the relationship between language and thought.  As a core part of Whorf’s theory complex, the linguistic relativity was once interpreted in two ways: linguistic determinism which means that language determines the way people think and linguistic relativism which implies that language influences the way people think.

The Kansas Geological Survey has conducted a major re-evaluation of the geology and seismicity of Kansas in connection with design criteria for dams, nuclear-power plants, and other earthquake-sensitive structures. Northeast Kansas was chosen as a study area because of the concentration of seismic activity and the stratigraphic evidence for the maximum amount of vertical displacement of the humboldt fault. This study determines the nature of the deformation on the Humboldt fault and resolves its lateral position and total vertical throw in the near-surface

HUMBOLDT the Navigator and his ChronometerA Contribution to the History of Navigation and OceanographyHUMBOLDT acquired a remarkable precision time-keeper instrument shortly before he left Paris for his Journey to the Neotropics (1799-1804. This chronometer was made by the famous Swiss-French watchmaker Louis BERTHOUD (1753-1813 with the series number 27. It had belonged to "the celebrated BORDA", as HUMBOLDT stated in his "Personal Narrative". Jean Louis BORDA (1733-1799 was a 18th century French navigator, mathematician and cartographer, who invented or improved a number of geomagnetic instruments. HUMBOLDT used this pocket chronometer for his routine astronomic and geomagnetic observations and to fix the longitude of his position while on board a vessel in the Atlantic and Pacific Ocean. Until John "Timekeeper" HARRISON developed his famous "H 4" chronometer in 1773, a strategic invention for a maritime power as Great Britain, the longitude was a major navigational problem. HUMBOLDT, who confessed that he had a "peculiar predelication for the sea", developed great nautical skills, and his findings were much better than those of the pilots. Furthermore he used the chronometer to observe and calculate ocean currents and to improve the geographical coordinates and thus the maps for many places in Latin America. So, beside his thermometer and barometer, the chronometer certainly was a very basic instrument in the state-of-the-art collection of scientific equipment he bought before leaving Europe.

The future of coastal upwelling in the Humboldt current from model projections

Science.gov (United States)

Oyarzún, Damián; Brierley, Chris M.

2018-03-01

The Humboldt coastal upwelling system in the eastern South Pacific ocean is one of the most productive marine ecosystems in the world. A weakening of the upwelling activity could lead to severe ecological impacts. As coastal upwelling in eastern boundary systems is mainly driven by wind stress, most studies so far have analysed wind patterns change through the 20th and 21st Centuries in order to understand and project the phenomenon under specific forcing scenarios. Mixed results have been reported, and analyses from General Circulation Models have suggested even contradictory trends of wind stress for the Humboldt system. In this study, we analyse the ocean upwelling directly in 13 models contributing to phase 5 of the Coupled Model Intercomparison Project (CMIP5) in both the historical simulations and an extreme climate change scenario (RCP8.5). The upwelling is represented by the upward ocean mass flux, a newly-included variable that represents the vertical water transport. Additionally, wind stress, ocean stratification, Ekman layer depth and thermocline depth were also analysed to explore their interactions with coastal upwelling throughout the period studied. The seasonal cycle of coastal upwelling differs between the Northern and Southern Humboldt areas. At lower latitudes, the upwelling season spans most of the autumn, winter and spring. However, in the Southern Humboldt area the upwelling season takes place in spring and the summertime with downwelling activity in winter. This persists throughout the Historical and RCP8.5 simulations. For both the Northern and Southern Humboldt areas an increasing wind stress is projected. However, different trends of upwelling intensity are observed away from the sea surface. Whereas wind stress will continue controlling the decadal variability of coastal upwelling on the whole ocean column analysed (surface to 300 m depth), an increasing disconnect with upwelling intensity is projected below 100 m depth throughout the 21

Diagnosing the Kaiser: Psychiatry, Wilhelm II and the Question of German War Guilt The William Bynum Prize Essay 2016.

Science.gov (United States)

Freis, David

2018-07-01

After his abdication in November 1918, the German emperor Wilhelm II continued to haunt the minds of his people. With the abolition of the lese-majesty laws in the new republic, many topics that were only discussed privately or obliquely before could now be broached openly. One of these topics was the mental state of the exiled Kaiser. Numerous psychiatrists, physicians and laypeople published their diagnoses of Wilhelm in high-circulation newspaper articles, pamphlets, and books shortly after the end of the war. Whether these diagnoses were accurate and whether the Kaiser really was mentally ill became the issue of a heated debate.This article situates these diagnoses of Wilhelm II in their political context. The authors of these diagnoses - none of whom had met or examined Wilhelm II in person - came from all political camps and they wrote with very different motives in mind. Diagnosing the exiled Kaiser as mentally ill was a kind of exorcism of the Hohenzollern rule, opening the way for either a socialist republic or the hoped-for rule of a new leader. But more importantly, it was a way to discuss and allocate political responsibility and culpability. Psychiatric diagnoses were used to exonerate both the Emperor (for whom the treaty of Versailles provided a tribunal as war criminal) and the German nation. They were also used to blame the Kaiser's entourage and groups that had allegedly manipulated the weak-willed monarch. Medical concepts became a vehicle for a debate on the key political questions in interwar Germany.

History of experimental psychology from an Estonian perspective.

Science.gov (United States)

Allik, Jüri

2007-11-01

A short review of the development of experimental psychology from an Estonian perspective is presented. The first rector after the reopening of the University of Dorpat (Tartu) in 1802, Georg Friedrich Parrot (1767-1852) was interested in optical phenomena which he attempted to explain by introducing the concept of unconscious inferences, anticipating a similar theory proposed by Herman von Helmholtz 20 years later. One of the next rectors, Alfred Wilhelm Volkmann (1800-1878) was regarded by Edwin Boring as one of the founding fathers of the experimental psychology. Georg Wilhelm Struve (1793-1864) played an essential part in solving the problem of personal equations. Arthur Joachim von Oettingen (1836-1920) developed a theory of music harmony, which stimulated his student Wilhelm Friedrich Ostwald (1853-1932) to study colour harmony. Emil Kraepelin (1856-1926), the founder of modern psychiatry, is by far the most important experimental psychologist who has worked in Estonia. His successor Wladimir von Tchisch (1855-1922), another student of Wilhelm Wundt, continued Kraepelin's work in experimental psychology. The lives of Wolfgang Köhler (1887-1967), who was born in Reval (Tallinn), and Oswald Külpe (1862-1915), who graduated from the University of Dorpat, extended the link between the history of experimental psychology and Estonia. Karl Gustav Girgensohn (1875-1925), the founder of the Dorpat School of the psychology of religion, stretched the use of experimental methods to the study of religious experience.

[Psychoanalysis during the Nazi era. Contemporary consequences of a historical controversy: the Wilhelm Reich "case"].

Science.gov (United States)

Nitzschke, B

1999-01-01

The paper sheds light on the extent of collaboration between the pre-World War II German Psychoanalytic Society (DPG) and the Nazi regime. This is shown by the story of the expulsion of Wilhelm Reich from membership in the DPG, at Freud's own bid. A leading German psychoanalyst, Carl Müller-Braunschweig, published the paper "Psychoanalysis and Weltanschauung" in the fanatically "national" (so-called "völkisch") Nazi propaganda organ Reichswart in 1993 following consultations with officials of the International Psychoanalytic Association (IPA) who endorsed these policies. This paper by Müller-Braunschweig was used both to prevent the possible outlawing of psychoanalysis by the Nazis and to deny official DPG support to Wilhelm Reich and the group of leftist-oriented IPA analysts who joined forces with him in opposing Nazi ideology. The paper concludes with examples from post-1945 historiography showing how the exclusion of Reich and the related DPG/IPA compromise and "appeasement" policy were either ignored or disclaimed.

Humboldt's spa: microbial diversity is controlled by temperature in geothermal environments.

Sharp, Christine E; Brady, Allyson L; Sharp, Glen H; Grasby, Stephen E; Stott, Matthew B; Dunfield, Peter F

2014-06-01

Over 200 years ago Alexander von Humboldt (1808) observed that plant and animal diversity peaks at tropical latitudes and decreases toward the poles, a trend he attributed to more favorable temperatures in the tropics. Studies to date suggest that this temperature-diversity gradient is weak or nonexistent for Bacteria and Archaea. To test the impacts of temperature as well as pH on bacterial and archaeal diversity, we performed pyrotag sequencing of 16S rRNA genes retrieved from 165 soil, sediment and biomat samples of 36 geothermal areas in Canada and New Zealand, covering a temperature range of 7.5-99 °C and a pH range of 1.8-9.0. This represents the widest ranges of temperature and pH yet examined in a single microbial diversity study. Species richness and diversity indices were strongly correlated to temperature, with R(2) values up to 0.62 for neutral-alkaline springs. The distributions were unimodal, with peak diversity at 24 °C and decreasing diversity at higher and lower temperature extremes. There was also a significant pH effect on diversity; however, in contrast to previous studies of soil microbial diversity, pH explained less of the variability (13-20%) than temperature in the geothermal samples. No correlation was observed between diversity values and latitude from the equator, and we therefore infer a direct temperature effect in our data set. These results demonstrate that temperature exerts a strong control on microbial diversity when considered over most of the temperature range within which life is possible.

De cómicos e histéricos. Una réplica a la sátira sobre eruditos de Daniel Kehlmann

Full Text Available Zusammenfassung Wie stark sich im Verlauf des zurückliegenden Vierteljahrhunderts der Bekanntheitsgrad Alexander von Humboldts in der deutschsprachigen Öffentlichkeit verändert hat, zeigen nicht nur Fernsehumfragen zu den berühmtesten Deutschen, in denen Alexander von Humboldt mittlerweile figuriert, oder Fernsehserien, die über aktuelle Expeditionen berichten und auf Humboldts Namen zurückgreifen. Am deutlichsten vielleicht belegt dies der enorme Erfolg von Daniel Kehlmanns Roman Die Vermessung der Welt, der ohne die zuvor skizzierte Entwicklung nicht denkbar gewesen wäre. Es ist vor diesem Hintergrund nicht nur reizvoll, sondern aufschlußreich, sich mit dem großen Erfolg dieses kleinen Romans zu beschäftigen. Worum geht es in Die Vermessung der Welt? Und wie läßt sich das „Phänomen Kehlmann“ aus etwas größerer Distanz erklären? Abstract In the last 25 years, Alexander von Humboldt‘s popularity has radically changed in the german-speaking public opinion. Proof of this are not only television surveys about the most famous germans - in which Alexander von Humboldt now regularly figures - or television series about contemporary expeditions, which constantly refer to Humboldt‘s name; perhaps what most clearly verifies this change is the great success of Daniel Kehlmann‘s novel Die Vermessung der Welt. Without the recent developments outlined above, this novel‘s degree of impact would have been unimaginable. To study the great success of this text against this backdrop is not only attractive, but also revealing. What is Die Vermessung der Welt really about? And how can we explain the „Kehlmann phenomenon“ from a greater distance? Resumen La popularidad de Alejandro de Humboldt ha cambiado profundamente dentro del último cuarto de siglo en la opinión pública de habla alemana. Prueba de esto son no sólo las encuestas televisivas sobre los alemanes más famosos, dentro de las cuales figura en estos momentos Alejandro

This study was initiated to expand upon previous findings that indicated concentrations of dissolved solids, arsenic, boron, mercury, molybdenum, selenium, and uranium were either above geochemical background concentrations or were approaching or exceeding ecological criteria in the lower Humboldt River system. Data were collected from May 1998 to September 2000 to further characterize streamflow and surface-water and bottom-sediment quality in the lower Humboldt River, selected agricultural drains, Upper Humboldt Lake, and Lower Humboldt Drain (ephemeral outflow from Humboldt Sink). During this study, flow in the lower Humboldt River was either at or above average. Flows in Army and Toulon Drains generally were higher than reported in previous investigations. An unnamed agricultural drain contributed a small amount to the flow measured in Army Drain. In general, measured concentrations of sodium, chloride, dissolved solids, arsenic, boron, molybdenum, and uranium were higher in water from agricultural drains than in Humboldt River water during this study. Mercury concentrations in water samples collected during the study period typically were below the laboratory reporting level. However, low-level mercury analyses showed that samples collected in August 1999 from Army Drain had higher mercury concentrations than those collected from the river or Toulon Drain or the Lower Humboldt Drain. Ecological criteria and effect concentrations for sodium, chloride, dissolved solids, arsenic, boron, mercury, and molybdenum were exceeded in some water samples collected as part of this study. Although water samples from the agricultural drains typically contained higher concentrations of sodium, chloride, dissolved solids, arsenic, boron, and uranium, greater instantaneous loads of these constituents were carried in the river near Lovelock than in agricultural drains during periods of high flow or non-irrigation. During this study, the high flows in the lower Humboldt River

Pedagogical experiment of the first rector of the Ural state mining institute P.P. Von Weymarn as an effort to reform the higher education institution in 1917-1920

Full Text Available Based on sources recently discovered and included in the database of scientific publications, the article analyzes the pedagogical activity of the scientist-chemist, the first rector and founder of the Ural Mining Institute in Ekaterinburg Petr Petrovich von Weymarn, whose name is now almost forgotten. The article shows that this activity can be evaluated as a pedagogical experiment on reformation of the higher education institution system, which could have been adopted in Russia if Bolsheviks lost the Civil War. Pedagogical activity of von Weymarn has a theoretical basis that he developed under the influence of Wilhelm Ostwald, the Nobel Prize winner in chemistry and the idealist philosopher, as well as the example of the Petrograd (Petersburg Mining Institute, which for von Weymarn was not only an alma mater but an example of a reformist attitudes toward the scientific and pedagogical process in higher education.The article gives a detailed analysis of the currently available philosophical and pedagogical essays of P.P. von Weymarn, known as «Essays on the Energy of Culture», as well as the practical application of these theoretical works on the basis of the Ural Mining Institute in Ekaterinburg and in Vladivostok.With the advent of Soviet power, von Weymarn's pedagogical experiment was forcibly interrupted, and he became «persona non-grata» in the Soviet Union, but now his name is being restored. Unfortunately, he is known either as a chemist or as the founder and first rector of the current Ural State Mining University, but not as a teacher who offered his view of reforming the higher school system. This article fills this gap, revealing not only the work of von Weymarn, but also describing the difficult period of changing the old scientific school system, which could have taken a completely different development path.

Some neglected contributions of Wilhelm Wundt to the psychology of memory.

Science.gov (United States)

Carpenter, Shana K

2005-08-01

Wilhelm Wundt, whose name is rarely associated with the scientific study of memory, conducted a number of memory experiments that appear to have escaped the awareness of modern cognitive psychologists. Aspects of Wundt's system are reviewed, particularly with respect to his experimental work on memory. Wundt investigated phenomena that would fall under the modern headings of iconic memory, short-term memory, and the enactment and generation effects, but this research has been neglected. Revisiting the Wundtian perspective may provide insight into some of the reasons behind the historical course of memory research and in general into the progress of science in psychology.

Alcuni “malintesi” di Wilhelm Röpke sull’ordo iuris ecclesiae

Domenico Bilotti

ABSTRACT: In spite of being widely regarded as a typical liberal conservative scholar, Wilhelm Röpke has shown a sincere interest on Canon Law’s history and social doctrine of the Church during his career and studies. The aim of this essay is to consider how Röpke tried to link this cultural and philosophical perspective to a strong adhesion to economics and liberalism. His theses maybe had an apologetic argumentative limit, just in order to justify his devotion to the Christian roots of European Law, but it does not mean that Röpke has not expressed any interesting issues, still useful in current juridical and confessional debate.

Hydrogeochemical studies of historical mining areas in the Humboldt River basin and adjacent areas, northern Nevada

Science.gov (United States)

Nash, J. Thomas

2005-01-01

The study area comprises the Humboldt River Basin and adjacent areas, with emphasis on mining areas relatively close to the Humboldt River. The basin comprises about 16,840 mi2 or 10,800,000 acres. The mineral resources of the Humboldt Basin have been investigated by many scientists over the past 100 years, but only recently has our knowledge of regional geology and mine geology been applied to the understanding and evaluation of mining effects on water and environmental quality. The investigations reported here apply some of the techniques and perspectives developed in the Abandoned Mine Lands Initiative (AMLI) of the U.S. Geological Survey (USGS), a program of integrated geological-hydrological-biological-chemical studies underway in the Upper Animas River watershed in Colorado and the Boulder River watershed in, Montana. The goal of my studies of sites and districts is to determine the character of mining-related contamination that is actively or potentially a threat to water quality and to estimate the potential for natural attenuation of that contamination. These geology-based studies and recommendations differ in matters of emphasis and data collection from the biology-based assessments that are the cornerstone of environmental regulations.

Humboldt, un prusiano en la Corte del Rey Carlos IV

Directory of Open Access Journals (Sweden)

Puig-Samper, Miguel Ángel

1999-08-01

Full Text Available The study of Alejandro de Humboldt's transit through Spain and particularly Madrid, has been one of the forgotten aspects of his historiography. The reasons that would explain the approval by king Charles IV of his trip, involving the minister Mariano de Urquijo and the embassador of Sajonia, baron of Forell, are not sufficiently documented due to the scarce data that Humboldt himself offered in his work and to the absence of any other supporting documents. This work studies the preparation of his American trip and its approval by the Spanish court. It incorporates the Memorandum presented —which was «lost» until now—, the autobiography submitted to the authorities and the references given by Philippe de Forrell. Furthermore, it analyses his relationships with the Spanish scientific community in Madrid and the profile of the team that supported him to achieve his targets.

El estudio del paso de Alejandro de Humboldt por España y especialmente por Madrid ha sido tradicionalmente uno de los aspectos más olvidados en la historiografía humboldtiana. La repetición de los pocos datos que él mismo ofreció en su obra y la falta de documentos ha hecho insuficiente la explicación de cómo fue aprobado su viaje por el rey Carlos IV, con la intervención del ministro Mariano Luis de Urquijo y del embajador de Sajonia, barón de Forell. En el presente trabajo se estudia la preparación de su viaje americano y su aprobación en la Corte española, aportando la Memoria presentada —abasta ahora «perdida»—, la autobiografía que elevó a las autoridades y el aval de Philippe de Forell. Asimismo se analizan sus relaciones con los científicos españoles en Madrid y el perfil del grupo que le ayudó a conseguir sus objetivos.

This Draft Environmental Statement (DES) contains th assessment of the environmental impact associated with decommissioning the Humboldt Bay Power Plant Unit 3 located 4 miles southwest of the city of Eureka, Humboldt County, California. This DES is prepared pursuant to the National Environmental Policy Act of 1969 (NEPA) and Title 10 of the Code of Federal Regulations, Part 51, as amended, of the Nuclear Regulatory Commission regulations. The proposed decommissioning would involve safe storage of the facility for about 30 years, after which the residual radioactivity would be removed so that the facility would be at levels of radioactivity acceptable for release of the facility to unrestricted access. 26 refs

Wilhelm Wundt's Theory of Interpretation

Directory of Open Access Journals (Sweden)

Jochen Fahrenberg

2008-09-01

Full Text Available Wilhelm WUNDT was a pioneer in experimental and physiological psychology. However, his theory of interpretation (hermeneutics remains virtually neglected. According to WUNDT psychology belongs to the domain of the humanities (Geisteswissenschaften, and, throughout his books and research, he advocated two basic methodologies: experimentation (as the means of controlled self-observation and interpretative analysis of mental processes and products. He was an experimental psychologist and a profound expert in traditional hermeneutics. Today, he still may be acknowledged as the author of the monumental Völkerpsychologie, but not his advances in epistemology and methodology. His subsequent work, the Logik (1908/1921, contains about 120 pages on hermeneutics. In the present article a number of issues are addressed. Noteworthy was WUNDT's general intention to account for the logical constituents and the psychological process of understanding, and his reflections on quality control. In general, WUNDT demanded methodological pluralism and a complementary approach to the study of consciousness and neurophysiological processes. In the present paper WUNDT's approach is related to the continuing controversy on basic issues in methodology; e.g. experimental and statistical methods vs. qualitative (hermeneutic methods. Varied explanations are given for the one-sided or distorted reception of WUNDT's methodology. Presently, in Germany the basic program of study in psychology lacks thorough teaching and training in qualitative (hermeneutic methods. Appropriate courses are not included in the curricula, in contrast to the training in experimental design, observation methods, and statistics. URN: urn:nbn:de:0114-fqs0803291

The timing of Late Pleistocene glaciation at Mount Wilhelm, Papua New Guinea

Mills, Stephanie; Barrows, Timothy; Hope, Geoff; Pillans, Brad; Fifield, Keith

2016-04-01

The highlands of New Guinea were the most extensively glaciated area in the Asian tropical region during the Late Pleistocene. Evidence for glaciation is widespread on most of the mountain peaks above ~3500 m. Glacial landforms include both valley and ice cap forms, but the timing of glaciation remains constrained to only a few local areas. This paper focuses on Mount Wilhelm, which is situated in the central southern region of Papua New Guinea at 5.78°S and is the highest peak (4510 m a.s.l.) We focus on a south easterly valley (Pindaunde Valley) emanating from the peak, where large moraines indicate the maximum ice extent of a valley glacier ~5 km long. Within this extensive moraine complex, recessional moraines document the retreat of the glacier towards the summit region. In order to determine the timing of deglaciation, we collected samples for surface exposure dating using 36Cl and 10Be from diorite boulders positioned on moraine crests. The ages indicate that maximum ice extent was attained during the last glacial maximum (LGM) and that ice remained near its maximum extent until after 15 ka but persisted at higher elevations almost until the Holocene. These results are similar to those described from Mt Giluwe to the northwest of Mount Wilhelm, where an ice cap reached its maximum extent at the LGM and remained there for around 3-4,000 years. This indicates that full glacial conditions were only brief in this region of the tropics.

What Would Humboldt Say: A Case of General Bildung in Vocational Education?

Directory of Open Access Journals (Sweden)

Ruhi Tyson

2016-12-01

Full Text Available A classic philosopher in the Bildung tradition, Humboldt argued that general Bildung was the opposite of specialist training (vocational education. This has been a matter of contention and the aim here is to revisit the issue through an empirical case study. In the vocational education biography of craft master Wolfgang B. he speaks about aspects of his education that have much in common with Humboldt’s ideal of general Bildung but transposed into the context of vocational education and training (VET. The concept of vocationalism (Beruflichkeit provides context to the present argument which is that the contrast Humboldt made is relevant but not in the sense of there being two categories of education (general and vocational but rather two expressions of pedagogy: one expansive and one exclusive. Furthermore, there are two versions of general or expansive Bildung present in the case. The conclusions are that empirical studies of vocational Bildung expand on the concept of Bildung, increase our understanding of how VET contains affordances of Bildung and of the curriculum-patterns related to this.

First pathological report of parasitic gastric ulceration in Humboldt penguin(Spheniscus humboldtialong the coast of south-central Chile Primera descripción patológica de úlceras gástricas parasitarias en el pingüino de Humboldt (Spheniscus humboldti en la costa centro-sur de Chile

Full Text Available This report offers a macroscopic and histological description of ulcerative gastric lesions in Humboldt penguins associated with the presence of Contracaecum pelagicum. Parasites of this genus have been isolated from different species of marine mammals and birds, including penguins, demonstrating its capacity to generate ulcerative lesions in the gastrointestinal tracts of many hosts. A bibliographic review revealed no publications on gastric ulceration by nematodes in Humboldt penguins. Studies carried out in Chile concerning gastrointestinal parasitism by nematodes of the Contracaecum genus in S. humboldti only established the parasite's taxonomy. This is the first pathological description of a parasitic ulcerative manifestation in the stomach of S. humboldti in the world. The Humboldt penguin is a vulnerable species. Therefore, this study is relevant as it offers a better understanding of the diseases that affect S. humboldti and facilitates the development of strategies intended to recover the population.El presente trabajo ofrece una descripción macroscópica e histológica de lesiones gástricas de tipo ulcerativas en el pingüino de Humboldt asociadas a la presencia de Contracaecum pelagicum.

La revisión bibliográfica reveló la ausencia de publicaciones relativas a cuadros ulcerativos gástricos causados por nemátodos en el pingüino de Humboldt. Los estudios realizados en Chile concernientes a parasitismo gastrointestinal por nemátodos del género Contracaecum en S. humboldti sólo han abordado aspectos taxonómicos.

Innovations from the “ivory tower”: Wilhelm Barthlott and the paradigm shift in surface science

Directory of Open Access Journals (Sweden)

Christoph Neinhuis

2017-02-01

Full Text Available This article is mainly about borders that have tremendous influence on our daily life, although many of them exist and act mostly unrecognized. In this article the first objective will be to address more generally the relation between university and society or industry, borders within universities, borders in thinking and the huge amount of misunderstandings and losses resulting from these obvious or hidden borders. In the second part and in more detail, the article will highlight the impact of the research conducted by Wilhelm Barthlott throughout his scientific career during which not only one border was removed, shifted or became more penetrable. Among the various fields of interest not mentioned here (e.g., systematics of Cactaceae, diversity and evolution of epiphytes, the unique natural history of isolated rocky outcrops called inselbergs, or the global distribution of biodiversity, plant surfaces and especially the tremendous diversity of minute structures on leaves, fruits, seeds and other parts of plants represent a common thread through 40 years of scientific career of Wilhelm Barthlott. Based on research that was regarded already old-fashioned in the 1970s and 1980s, systematic botany, results and knowledge were accumulated that, some 20 years later, initiated a fundamental turnover in how surfaces were recognized not only in biology, but even more evident in materials science.

Age,maturation and population structure of the Humboldt squid Dosidicus gigas were studied based on random sampling of the Chinese jigging fishery off the Peruvian Exclusive Economic Zones (EEZ) during 2008-2010.Estimated ages ranged from 144 to 633 days,confirming that the squid is a short-lived species with longevity no longer than 2 years.Occurrence of mature females and hatching in each month indicated that Humboldt squid spawned year-round.Back-calculated hatching dates for the samples were from January 22nd,2008 to April 22nd,2010 with a peak between January and March.Two size-based and two hatching date-based populations could be defined from mantle length (ML) at maturity and back-calculated hatching dates,respectively.Females matured at a larger size than males,and there was a significant difference in ML at maturity between the two hatching groups (P＜0.05).The waters adjacent to 11°S off the Peruvian EEZ may be a potential spawning ground.This study shows the complexity of the population structure and large variability in key life history parameters in the Humboldt squid off the Peruvian EEZ,which should be considered in the assessment and management of this important resource.

Genetics as a modernization program: biological research at the Kaiser Wilhelm Institutes and the political economy of the Nazi State.

Science.gov (United States)

Gausemeier, Bernd

2010-01-01

During the Third Reich, the biological institutes of the Kaiser Wilhelm Society (KWG, Kaiser-Wilhelm-Gesellschaft) underwent a substantial reorganization and modernization. This paper discusses the development of projects in the fields of biochemical genetics, virus research, radiation genetics, and plant genetics that were initiated in those years. These cases exemplify, on the one hand, the political conditions for biological research in the Nazi state. They highlight how leading scientists advanced their projects by building close ties with politicians and science-funding organizations and companies. On the other hand, the study examines how the contents of research were shaped by, and how they contributed to, the aims and needs of the political economy of the Nazi system. This paper therefore aims not only to highlight basic aspects of scientific development under Nazism, but also to provide general insights into the structure of the Third Reich and the dynamics of its war economy.

Humboldt SK pilot biodigester receives funding

Energy Technology Data Exchange (ETDEWEB)

Anon.

2005-09-30

The Canada-Saskatchewan Western Economic Partnership Agreement (WEPA) will provide funding for Canada's first pilot-scale biodigester to be built in Humboldt, Saskatchewan. The $208,138 pilot facility will use household garbage as well as agricultural waste such as manure and livestock operations, abattoirs and food processing to create heat or power and fertilizer. Support for this bio-energy facility, which could also reduce greenhouse gases, will come from the Prairie Agricultural Machinery Institute which has received $186,138 from Canada and Saskatchewan in the form of cost-shared federal-provincial funding. The pilot plant will test different combinations of waste material feedstocks and the characteristics of the resulting gas end products. The pilot facility will also provide design information for full-scale biodigester manufacturers in Canada. It is expected that 25 full-scale biodigesters will be constructed in Canada in the near future.

Wilhelm Wundt (1832-1920) believed that consciousness was represented by the interconnection of psychical processes comprised of temporal elements and compounds. To explore these processes, Wundt used a metronome to measure the amount of information that passed into consciousness across time. The current project replicated some of his procedures,…

This paper is intended to celebrate the 120th anniversary of the discovery of X-rays. X-rays (Roentgen-rays) were discovered on the 8th ofNovember, 1895 by the German physicist Wilhelm Conrad Roentgen. Fifty days after the discovery of X-ray, on December 28, 1895. Wilhelm Conrad Roentgen published a paper about the discovery of X-rays - "On a new kind of rays" (Wilhelm Conrad Roentgen: Ober eine neue Art von Strahlen. In: Sitzungsberichte der Wurzburger Physik.-Medic.- Gesellschaft. 1895.). Therefore, the date of 28th ofDecember, 1895 was taken as the date of X-rays discovery. This paper describes the work of Wilhelm Conrad Roentgen, Nikola Tesla, Mihajlo Pupin and Maria Sklodowska-Curie about the nature of X-rays . The fantastic four - Wilhelm Conrad Roentgen, NikolaTesla, Mihajlo ldvorski Pupin and Maria Sklodowska-Curie set the foundation of radiology with their discovery and study of X-rays. Five years after the discovery of X-rays, in 1900, Dr Avram Vinaver had the first X-ray machine installed in abac, in Serbia at the time when many developed countries did not have an X-ray machine and thus set the foundation of radiology in Serbia.

The evolutionary and adaptive potential of populations or species facing an emerging infectious disease depends on their genetic diversity in genes, such as the major histocompatibility complex (MHC). In birds, MHC class I deals predominantly with intracellular infections (e.g., viruses) and MHC class II with extracellular infections (e.g., bacteria). Therefore, patterns of MHC I and II diversity may differ between species and across populations of species depending on the relative effect of local and global environmental selective pressures, genetic drift, and gene flow. We hypothesize that high gene flow among populations of Humboldt and Magellanic penguins limits local adaptation in MHC I and MHC II, and signatures of selection differ between markers, locations, and species. We evaluated the MHC I and II diversity using 454 next-generation sequencing of 100 Humboldt and 75 Magellanic penguins from seven different breeding colonies. Higher genetic diversity was observed in MHC I than MHC II for both species, explained by more than one MHC I loci identified. Large population sizes, high gene flow, and/or similar selection pressures maintain diversity but limit local adaptation in MHC I. A pattern of isolation by distance was observed for MHC II for Humboldt penguin suggesting local adaptation, mainly on the northernmost studied locality. Furthermore, trans-species alleles were found due to a recent speciation for the genus or convergent evolution. High MHC I and MHC II gene diversity described is extremely advantageous for the long-term survival of the species.

Decommissioning of the Humboldt Bay Power Plant, Unit No. 3, Docket No. 50-133, Humboldt County, California

1986-04-01

A draft environmental impact statement (EPA No. 860164D) on plans to decommission unit 3 of the Humboldt Bay reactor in California. The reactor was shutdown in 1976 for seismic modifications after 13 years of operation, but decommissioning proved more economical. The plan calls for retaining spent fuel on the site until a federal repository is available. The utility has established a radiation protection program to limit exposures. Safe storage of the facility is possible for about 30 years, but a fuel-handling or other accident could lead to the release of radionuclides into the atmosphere. A rupture of the spent fuel pool or the liquid radwaste tanks could contaminate the seafood chain, but doses received during recreational use of the bay would be negligible. The Federal Waste Pollution Control Act of 1972 and Nuclear Waste Policy Act of 1982 require the impact statement

Observations made by Plafker in Chile (1960) and Alaska (1964) show that vertical deformation during earthquakes is generally opposite in sense of motion compared to interseismic deformation. This elastic rebound theory drives estimates of potential coseismic deformation on the Cascadia subduction zone (CSZ). Similar to other coastal marshes along the CSZ, paleoseismic investigations around Humboldt Bay reveal evidence of coseismic subsidence for the past 4 ka. Tide gage data obtained from NOAA tide gages, as well as 'campaign' style tide gages, are used to infer interseismic ground deformation. Tide gage data from Crescent City and Humboldt Bay are compared to each other and also compared to estimates of eustatic sea-level rise to estimate rates of land-level change. Earthscope and USGS GPS permanent site data are also used to evaluate vertical interseismic deformation in this region. These rates of land-level change are then compared to paleoseismic proxies for vertical land-level change. Cores collected for master's theses research at Humboldt State University were used to compile an earthquake history for the Humboldt Bay region. Some cores in Mad River and Hookton sloughs were used to evaluate magnitudes of coseismic subsidence by comparing diatom and foraminiferid assemblages associated with lithologic contacts (paleogeodesy). Minimum estimates of paleosubsidence for earthquakes range from 0.3 to 2.6 meters. Subtracting eustatic sea-level rise (~2.3 mm/yr, 1977-2010) from Crescent City (CC) and North Spit (NS) relative sea-level rates reveals that CC is uplifting at ~3mm/yr and NS is subsiding at ~2.5 mm/yr. GPS vertical deformation reveals similar rates of ~3 mm/yr of uplift and ~2 mm/yr of subsidence in these two locations. GPS based subsidence rates show a gradient of subsidence between Trinidad (in the north) to Cape Mendocino (in the south). The spatial region of ongoing subsidence reveals the depth of locking of the CSZ fault (differently from previous

Research is a main element for human and social development. Under this point of view, it involves particular challenges and opportunities for the so-called "developing countries". An approach for those challenges and opportunities comes from the analysis of two interrelated activities; the training of new researchers and the research development with institutions or researchers which are external to the institution ("collaborative research"). Both activities are essential for the consolidation, widening and updating of the institutional capabilities for scientific production. We present here the experiences of the Instituto de Medicina Tropical "Alexander von Humboldt" of the Universidad Peruana Cayetano Heredia, in relation to the training of new researchers, we discuss the four elements we consider key for this process; the promotion of stimulating environments for research, the proactive identification of fellows, the complementary advice and networks consolidation; and we analyze three successful models of international collaboration for the training of new researchers under different institutional approaches.

Acceleration of Humboldt glacier, north Greenland

Here we report on recent abrupt acceleration on the flow speed of Humboldt Glacier (HG) in northern Greenland. The mean annual discharge of this glacier in 2000 was estimated as 8.4Gt/a, placing it among the largest outlet glacier draining the northern coast (Enderlin et al., 2014). Using a combination of remote sensing datasets, we find that following a slight slowing before 2010, HG suddenly sped up by a factor of three between 2012 and 2013, maintaining that increased speed through 2016. Speedup was accompanied by up to 10 m of thinning near the terminus and followed slower, longer-term thinning and retreat. Here we assess possible causes for the speedup, potential for continued acceleration and implication to ice sheet mass balance. ReferenceEnderlin, E. M., I. M. Howat, S. Jeong, M.-J. Noh, J.

Humboldtian science, Creole meteorology, and the discovery of human-caused climate change in South America.

Cushman, Gregory T

2011-01-01

The belief that human land use is capable of causing large-scale climatic change lies at the root of modern conservation thought and policy. The origins and popularization of this belief were deeply politicized. Alexander von Humboldt's treatment of the Lake Valencia basin in Venezuela and the desert coast of Peru as natural laboratories for observing the interaction between geophysical and cultural forces was central to this discovery, as was Humboldt's belief that European colonialism was especially destructive to the land. Humboldt's overt cultivation of disciples was critical to building the prestige of this discovery and popularizing the Humboldtian scientific program, which depended fundamentally on local observers, but willfully marginalized chorographic knowledge systems. In creating new, global forms of environmental understanding, Humboldtian science also generated new forms of ignorance.

But many of them have failed to see the bright side of Tommy’s character. He possesses rare human qualities completely alien to the citizens of a morally corrupt society. The article aims to  prove that in spite of possessing various negative and unheroic qualities, Tommy, by defying social structure and network, asserts his non-conformity which, along with his humanity, love and philanthropy, aversion for power and material success and most importantly, his power of overcoming humiliation, secures him the position of a hero although an untraditional one. The narrative structure also plays a significant role behind his being a hero. Keywords: Materialism, Untraditional hero, Humanity, Non-conformity

The holist tradition in twentieth century genetics. Wilhelm Johannsen's genotype concept.

Science.gov (United States)

Roll-Hansen, Nils

2014-06-01

The terms 'genotype', 'phenotype' and 'gene' originally had a different meaning from that in the Modern Synthesis. These terms were coined in the first decade of the twentieth century by the Danish plant physiologist Wilhelm Johannsen. His bean selection experiment and his theoretical analysis of the difference between genotype and phenotype were important inputs to the formation of genetics as a well-defined special discipline. This paper shows how Johannsen's holistic genotype theory provided a platform for criticism of narrowly genocentric versions of the chromosome theory of heredity that came to dominate genetics in the middle decades of the twentieth century. Johannsen came to recognize the epoch-making importance of the work done by the Drosophila group, but he continued to insist on the incompleteness of the chromosome theory. Genes of the kind that they mapped on the chromosomes could only give a partial explanation of biological heredity and evolution. © 2014 The Author.

X-ray K-edge analysis of drain lines in Wilhelm Hall, Ames Laboratory

International Nuclear Information System (INIS)

Jensen, T.; Whitmore, C.; Iowa State Univ., Ames, IA

1999-01-01

From August 12--27, 1998 X-ray K-edge measurements were made on drain lines in seven rooms in Wilhelm Hall, Ames Laboratory. The purpose of these measurements was to determine the extent of thorium (and other heavy metal) contamination inside these pipes. The K-edge method is a noninvasive inspection technique that can provide accurate quantification of heavy metal contamination interior to an object. Of the seven drain lines inspected, one was found to have no significant contamination, three showed significant thorium deposits, two showed mercury contamination, and one line was found to contain mercury, thorium and uranium. The K-edge measurements were found to be consistent with readings from hand-held survey meters, and provided much greater detail on the location and amount of heavy metal contamination

Overview of mine drainage geochemistry at historical mines, Humboldt River basin and adjacent mining areas, Nevada. Chapter E.

Science.gov (United States)

Nash, J. Thomas; Stillings, Lisa L.

2004-01-01

Reconnaissance hydrogeochemical studies of the Humboldt River basin and adjacent areas of northern Nevada have identified local sources of acidic waters generated by historical mine workings and mine waste. The mine-related acidic waters are rare and generally flow less than a kilometer before being neutralized by natural processes. Where waters have a pH of less than about 3, particularly in the presence of sulfide minerals, the waters take on high to extremely high concentrations of many potentially toxic metals. The processes that create these acidic, metal-rich waters in Nevada are the same as for other parts of the world, but the scale of transport and the fate of metals are much more localized because of the ubiquitous presence of caliche soils. Acid mine drainage is rare in historical mining districts of northern Nevada, and the volume of drainage rarely exceeds about 20 gpm. My findings are in close agreement with those of Price and others (1995) who estimated that less than 0.05 percent of inactive and abandoned mines in Nevada are likely to be a concern for acid mine drainage. Most historical mining districts have no draining mines. Only in two districts (Hilltop and National) does water affected by mining flow into streams of significant size and length (more than 8 km). Water quality in even the worst cases is naturally attenuated to meet water-quality standards within about 1 km of the source. Only a few historical mines release acidic water with elevated metal concentrations to small streams that reach the Humboldt River, and these contaminants and are not detectable in the Humboldt. These reconnaissance studies offer encouraging evidence that abandoned mines in Nevada create only minimal and local water-quality problems. Natural attenuation processes are sufficient to compensate for these relatively small sources of contamination. These results may provide useful analogs for future mining in the Humboldt River basin, but attention must be given to

The evolution of seabirds in the Humboldt Current: new clues from the Pliocene of Central Chile.

Directory of Open Access Journals (Sweden)

Martín Chávez Hoffmeister

Full Text Available During the last decade, new Neogene fossil assemblages from South America have revealed important clues about the evolution of seabird faunas in one of the major upwelling systems of the world: the Humboldt Current. However, most of this record comes from arid Northern Chile and Southern Peru and, in consequence, our knowledge of the evolutionary history of seabirds in the temperate transitional zone is negligible. A new Late Pliocene assemblage of fossil birds from the coastal locality of Horcon in Central Chile offers a unique opportunity to fill this gap.Isolated bones of a medium-sized penguin are the most abundant bird remains. Morphological and cladistic analyses reveal that these specimens represent a new species of crested penguin, Eudyptes calauina sp. nov. Eudyptes is a penguin genus that inhabit temperate and subantarctic regions and currently absent in central Chile. Additionally, a partial skeleton of a small species of cormorant and a partial tarsometatarsus of a sooty shearwater have been identified.The Horcon fossils suggest the existence of a mixed avifauna in central Chile during the Pliocene in concordance with the latitudinal thermal gradient. This resembles the current assemblages from the transitional zone, with the presence of species shared with Northern Chile and Southern Peru and a previously unrecorded penguin currently absent from the Humboldt System but present in the Magellanic region. Comparison of Pliocene seabird diversity across the Pacific coast of South America shows that the Horcon avifauna represents a distinctive assemblage linking the living faunas with the Late Miocene ones. A comparison with the fossil record near the Benguela Current (west coast of southern Africa suggests that the thermic gradient could play an important role in the preservation of a higher diversity of cold/temperate seabirds in the Humboldt Current.

Wilhelm Troll (1897 - 1978): idealistic morphology, physics, and phylogenetics.

Science.gov (United States)

Rieppel, Olivier

2011-01-01

Idealistic morphology as articulated by the botanist Wilhelm Troll, the main target of the critique voiced by the early phylogeneticists, was firmly embedded in its contemporary scientific, cultural, and political context. Troll appealed to theoretical developments in contemporary physics in support of his research program. He understood burgeoning quantum mechanics not only to threaten the unity of physics, but also the validity of the principle of causality. Troll used this insight in support of his claim of a dualism in biology, relegating the causal-analytical approach to physiology, while rejuvenating the Goethean paradigm in comparative morphology. This embedded idealistic morphology in the völkisch tradition that characterized German culture during the Weimar Republic and its aftermath. In contrast, the contemporary phylogeneticists anchored their research program in the rise of logical positivism and in Darwin's principle of natural selection. This, in turn, brought phylogenetic systematists of the late 1930s and early 1940s into the orbit of national-socialist racial theory and eugenics. In conclusion, the early debate between idealistic morphologists and phylogenetic systematists was not only ideologically tainted, but also implied a philosophical impasse that is best characterized as a conflict between the Goethean and Newtonian paradigm of natural science.

Closing and opening fisheries following oil spills; a case study in Humboldt Bay, California

International Nuclear Information System (INIS)

Challenger, G.E.; Mauseth, G.S.

1998-01-01

The issue of fishery evaluation criteria following oil spills in lakes, rivers and seas was discussed. The case of the November 1997 incident in which 4,450 gallons of an intermediate fuel oil was released into Humboldt Bay, California was described. Humboldt Bay contains important shellfish mariculture operations that were subsequently closed by the California Dept. of Health Services (CDHS). The closure and reopening protocols for the fishery were summarized. Suggestions for technical input to resource management decisions were presented. During an initial meeting with regulatory agencies, four levels of criteria were established for rescinding the fishery closure. The fishery closure would be rescinded when: (1) there was a lack of visible oil sheen on the water throughout the commercial growing areas, (2) shellfish tissue samples met the risk-based criteria developed by CDHS, for all analytes of concern in the source oil, (3) all water samples met the risk-based criteria developed by CDHS for all analytes of concern in the source oil, and (4) tissue samples passed an independent sensory evaluation. However, no risk-based water quality criteria were developed and only items 1, 2, and 4 were included in the analysis. 15 refs., 3 tabs., 1 fig

Seiler, R.L.; Ekechukwu, G.A.; Hallock, R.J.

1993-01-01

A reconnaissance investigation was begun in 1990 to determine whether the quality of irrigation drainage in and near the Humboldt Wildlife Management Area, Nevada, has caused or has the potential to cause harmful effects on human health, fish, and wildlife or to impair beneficial uses of water. Samples of surface and ground water, bottom sediment, and biota collected from sites upstream and downstream from the Lovelock agricultural area were analyzed for potentially toxic trace elements. Also analyzed were radioactive substances, major dissolved constitu- ents, and nutrients in water, as well as pesticide residues in bottom sediment and biota. In samples from areas affected by irrigation drainage, the following constituents equaled or exceeded baseline concentrations or recommended standards for protection of aquatic life or propagation of wildlife--in water: arsenic, boron, dissolved solids, mercury, molybdenum, selenium, sodium, and un-ionized ammonia; in bottom sediment; arsenic and uranium; and in biota; arsenic, boron, and selenium. Selenium appears to be biomagnified in the Humboldt Sink wetlands. Biological effects observed during the reconnaissance included reduced insect diversity in sites receiving irrigation drainage and acute toxicity of drain water and sediment to test organisms. The current drought and upstream consumption of water for irrigation have reduced water deliveries to the wetlands and caused habitat degradation at Humboldt Wildlife Management Area. During this investigation. Humboldt and Toulon Lakes evaporated to dryness because of the reduced water deliveries.

Full Text Available Zusammenfassung Der Forschungsreisende Francis Hall kam als Soldat nach Südamerika und betätigte sich hier auch als Pflanzensammler, Reiseschriftsteller und Bergsteiger. Er war Freund und Briefpartner Jeremy Benthams und versuchte gemeinsam mit Jean-Baptiste Boussingault den Chimborazo zu besteigen. Der liberale Journalist wurde 1833 in bürgerkriegsähnlichen Unruhen in Ecuador ermordet. Der einzige Brief Halls an Humboldt, in dem er diesen für die Naturerschließung des Landes zu gewinnen versucht, eine Sammlung andiner Pflanzen übersendet und seine Einschätzung zur politischen Lage und Zukunft Südamerikas kundtut, wird hier veröffentlicht und kommentiert. Abstract The British explorer Francis Hall was active in South-America as a soldier, a collector of plants, a writer of travelogues and a mountaineer. Together with Jean-Baptiste Boussingault he failed in ascending the Chimborazo. Friend and correspondent of Jeremy Bentham and also liberal journalist, Hall was killed during riots in Ecuador in 1833. In one single letter addressed to Humboldt, which is presented here, Hall tries to awaken interest for Ecuador, develops his views on the political future of South America and sends a collection of plants from the Andes. Resumen El explorador británico Francis Hall llegó a América del Sur como soldado y allí también se dedicó a la colección de plantas, a escribir sobre viajes y a hacer alpinismo. Intentó subir al Chimborazo con Jean-Baptiste Boussingault. El periodista liberal, amigo de Jeremy Bentham con el que también mantenía correspondencia, fue asesinado en los disturbios de 1833 en Ecuador. En la única carta de Hall a Humboldt, que está publicada y comentada aquí, Hall intenta despertar el interés de Humboldt por la naturaleza del país enviando una colección de plantas andinas y dando su opinión sobre la situación política y el futuro de América del Sur.

Titanisierung von Implantatoberflächen

Science.gov (United States)

Zimmermann, Hanngörg; Heinlein, Markus; Guldner, Norbert W.

Titan gilt seit Jahrzehnten als einer der wichtigsten Implantatwerkstoffe in der Medizin. Neben den guten mechanischen Eigenschaften (Leichtigkeit, hohe Festigkeit etc.), besitzen Titanimplantate vor allem eine hervorragende Körperverträglichkeit, so dass die Implantate optimal in den humanen Organismus integriert werden [1]. Ist jedoch aufgrund der Anforderungen an das Implantat eine hohe Flexibilität und/ oder Elastizität gefragt, so scheidet der Werkstoff Titan aufgrund seiner spröden und unflexiblen Materialeigenschaften aus. Die Folge ist der Einsatz von Implantatmaterialien, sowohl künstlichen als auch biologischen Ursprungs, welche nicht selten eine unzureichende Biokompatibilität aufweisen und somit zu Fremdköper- und immunologischen Reaktionen und Einkapselung des Implantates führen können. Die Erhöhung der Körperverträglichkeit, eine Adaption an das biologische Umfeld und eine hohe Biokompatibilität sind demzufolge die wichtigsten Eigenschaften bei der bedarfsgerechten Herstellung von Implantaten und Implantatoberflächen. Zur Gestaltung von innovativen, biokompatiblen Oberflächen stehen unterschiedliche technische Lösungsansätze zur Verfügung. Zum einen besteht die Möglichkeit, geeignete Oberflächeneigenschaften aus dem Grundmaterial selbst zu optimieren. Dies geschieht unter anderem durch Modifikation der Werkstoffoberflächen in Form von Texturierungen und Oberflächenrauhigkeiten. Zum anderen können die Oberflächeneigenschaften unabhängig von denen des Trägermaterials gestaltet werden. Durch Funktionalisierung der Oberflächen mit geeigneten Beschichtungen oder der Zugabe von Medikamenten (Drug Eluting) werden die Kunststoffimplantate dahingehend verändert, dass eine Steigerung der Körperakzeptanz erreicht wird. Die Titanbeschichtung von Implantatoberflächen kombiniert die positiven Materialeigenschaften von Titan und Polymer.

The sing for Humboldt, for Saussure and for Bakhtin

Directory of Open Access Journals (Sweden)

Sebastião Elias Milani

2015-01-01

Full Text Available This article shows three of the principal sign conceptions of the studies about language, differences and similarities. The sign is for Humboldt the material representation, or sound-image, of the concept, besides the identity of the articulated language sound; these three parts, sign, concept and sound identity, make the form of the language that is the word. The sign is for Saussure the name of the relation between the signified and the signifier. Saussure proposed the substitution of the terms sound-image and concept, that were full of suggestions and prior conceptualization, to the terms signified and signifier. The sign in Bakhtin is the form of the structure that accomplishes an ideologically sense completed by thought through articulated sound. The meeting between the articulated sound and the concept gives the resulting element of semiosis, so every sign is semiotic.

Trophic relationships between the jumbo squid (Dosidicus gigas and the lightfish (Vinciguerria lucetia in the Humboldt Current System off Peru

Directory of Open Access Journals (Sweden)

Rigoberto Rosas-Luis

2011-04-01

Full Text Available Acoustic surveys for assessing the biomass and distribution of the jumbo squid (Dosidicus gigas and the lightfish (Vinciguerria lucetia were carried out in the Humboldt Current System of Peru in 2007 and 2008. At the same time, 937 jumbo squid were caught and their stomach contents analyzed. The diet of the jumbo squid was dominated by mesopelagic fish. The first component of their fish diet was V. lucetia and the second component was the myctophid fish Diogenichthys laternatus. Acoustic biomass estimates of these species show that V. lucetia is an important component in aggregative structures in the Humboldt Current System of Peru and its distribution and movements are closely related to the migratory movements of the jumbo squid. The trophic relationship observed between D. gigas and V. lucetia promotes an increase in jumbo squid biomass and, has a positive trophic effect on the ocean ecosystem.

Effects of November 8, 1980 earthquake on Humboldt Bay Power Plant and Eureka, California area. Reconnaissance report 13 Nov-14 Nov 80

International Nuclear Information System (INIS)

Herring, K.S.; Rooney, V.; Chokshi, N.C.

1981-06-01

On November 8, 1980, an earthquake of a reported surface wave magnitude of 7.0 occurred off the coast of California, west of Eureka and the Humboldt Bay Power Plant. Three NRC staff members visited the site the following week to survey any damage associated with the earthquake, with the objective of using collected data to assist the NRR staff in ongoing seismic evaluations of older operating nuclear power plant facilities. This report contains their observations. They concluded that the effects of the earthquake on Humboldt Bay Power Plant Unit 3 were minimal and did not endanger the health and safety of the public. They recommended that improvements be made to seismic recording equipment and that generic preparation for future post-earthquake reconnaissance trips be made before the actual occurrence of earthquakes

Laughlin, D S; Ialeggio, D M; Trupkiewicz, J G; Sleeper, M M

2016-09-01

The Eisenmenger ventricular septal defect is an uncommon type of ventricular septal defect characterised in humans by a traditionally perimembranous ventricular septal defect, anterior deviation (cranioventral deviation in small animal patients) of the muscular outlet septum causing malalignment relative to the remainder of the muscular septum, and overriding of the aortic valve. This anomaly is reported infrequently in human patients and was identified in a 45-day-old Humboldt Penguin, Spheniscus humboldti, with signs of poor growth and a cardiac murmur. This case report describes the findings in this penguin and summarises the anatomy and classification of this cardiac anomaly. To the authors' knowledge this is the first report of an Eisenmenger ventricular septal defect in a veterinary patient. Copyright © 2016 Elsevier B.V. All rights reserved.

Selection within organisms in the nineteenth century: Wilhelm Roux's complex legacy.

Science.gov (United States)

Heams, Thomas

2012-09-01

Selectionism, or the extension of darwinian chance/selection dynamics beyond the individual level, has a long history in biological thought. It has generated important theories in immunology or neurology, and turns out to be a convincing framework to account for the intrinsic stochastic nature of core events in cellular biology. When looking back at the intellectual origins of selectionism, the essay by the German embryologist Wilhelm Roux, Der Kampf der Theile im Organismus (The Struggle of the Parts in the Organism - 1881) might be one, if not the earliest reference after the darwinian revolution. It describes the individual as a multilevel structure, where each level results from a 'darwinian' struggle of its parts (molecules, cells, tissues, organs). But Roux's theory, far from being a simple extension of natural selection, has complex and even conflictual relationships with darwinism. This essay is worth rediscovering as a subtle historical testimony of the evolutionary and developmental life sciences debates of its time. Moreover, some of its theses may also enrich some current debates among evolutionary biologists over levels of selection, and among cellular and molecular biologists over the status of determinism in biology today.

The role of tone sensation and musical stimuli in early experimental psychology.

Science.gov (United States)

Klempe, Sven Hroar

2011-01-01

In this article, the role of music in early experimental psychology is examined. Initially, the research of Wilhelm Wundt is considered, as tone sensation and musical elements appear as dominant factors in much of his work. It is hypothesized that this approach was motivated by an understanding of psychology that dates back to Christian Wolff 's focus on sensation in his empirical psychology of 1732. Wolff, however, had built his systematization of psychology on Gottfried Wilhelm von Leibniz, who combined perception with mathematics,and referred to music as the area in which sensation is united with numerical exactitude. Immanuel Kant refused to accept empirical psychology as a science, whereas Johann Friedrich Herbart reintroduced the scientific basis of empirical psychology by, among other things, referring to music.

Attributing Authorship in the Noisy Digitized Correspondence of Jacob and Wilhelm Grimm

Directory of Open Access Journals (Sweden)

Greta Franzini

2018-04-01

Full Text Available This article presents the results of a multidisciplinary project aimed at better understanding the impact of different digitization strategies in computational text analysis. More specifically, it describes an effort to automatically discern the authorship of Jacob and Wilhelm Grimm in a body of uncorrected correspondence processed by HTR (Handwritten Text Recognition and OCR (Optical Character Recognition, reporting on the effect this noise has on the analyses necessary to computationally identify the different writing style of the two brothers. In summary, our findings show that OCR digitization serves as a reliable proxy for the more painstaking process of manual digitization, at least when it comes to authorship attribution. Our results suggest that attribution is viable even when using training and test sets from different digitization pipelines. With regards to HTR, this research demonstrates that even though automated transcription significantly increases the risk of text misclassification when compared to OCR, a cleanliness above ≈ 20% is already sufficient to achieve a higher-than-chance probability of correct binary attribution.

Verbesserung der Symmetrie von Hirnaufnahmen entlang der Sagittalebene

Science.gov (United States)

Ens, Konstantin; Wenzel, Fabian; Fischer, Bernd

Die lokale Symmetrie von Hirnscans entlang der Sagittalebene zu ermitteln und zu modizifieren, ist für eine Reihe neurologischer Anwendungen interessant. Beispielsweise kann der voxelweise Vergleich von rechter und linker Hirnhälfte nur dann Aufschluss über die Lokalisierung von Läsionen geben, wenn durch Transformation ein Hirnscan eine möglichst hohe Symmetrie aufweist. Ein weiteres Anwendungsgebiet ist die Visualisierung von medialen Hirnschnitten, für die die Trennfläche beider Hirnhälfte möglichst eben sein sollte. Diese Arbeit stellt die Entwicklung eines Verfahrens vor, mit dessen Hilfe die Symmetrie von Hirnaufnahmen entlang der Sagittalebene verbessert werden kann. Dies geschieht unter Verwendung von aktiven Konturen, die mit Hilfe einer neuartigen Kostenfunktion gesteuert werden. Experimente am Ende der Arbeit mit strukturellen Kernspinaufnahmen demonstrieren die Leistungsfähigkeit des Verfahrens.

The 395th Wilhelm and Else Heraeus Seminar: `Time-dependent phenomena in Quantum Mechanics' took place at the Heinrich Fabri Institute in Blaubeuren, Germany, 12-16 September 2007. The conference covered a wide range of topics connected with time-dependent phenomena in quantum mechanical systems. The 20 invited talks and 15 short talks with posters at the workshop covered the historical debate between Schrödinger, Dirac and Pauli about the role of time in Quantum Mechanics (the debate was carried out sometimes in footnotes) up to the almost direct observation of electron dynamics on the attosecond time-scale. Semiclassical methods, time-delay, monodromy, variational principles and quasi-resonances are just some of the themes which are discussed in more detail in the papers. Time-dependent methods also shed new light on energy-dependent systems, where the detour of studying the time-evolution of a quantum states allows one to solve previously intractable problems. Additional information is available at the conference webpage http://www.quantumdynamics.de The organizer would like to thank all speakers, contributors, session chairs and referees for their efforts in making the conference a success. We also gratefully acknowledge the generous financial support from the Wilhelm and Else Heraeus Foundation for the conference and the production of this special volume of Journal of Physics: Conference Series.

A note on derivations of Murray–von Neumann algebras

Kadison, Richard V.; Liu, Zhe

2014-01-01

A Murray–von Neumann algebra is the algebra of operators affiliated with a finite von Neumann algebra. In this article, we first present a brief introduction to the theory of derivations of operator algebras from both the physical and mathematical points of view. We then describe our recent work on derivations of Murray–von Neumann algebras. We show that the “extended derivations” of a Murray–von Neumann algebra, those that map the associated finite von Neumann algebra into itself, are inner. In particular, we prove that the only derivation that maps a Murray–von Neumann algebra associated with a factor of type II1 into that factor is 0. Those results are extensions of Singer’s seminal result answering a question of Kaplansky, as applied to von Neumann algebras: The algebra may be noncommutative and may even contain unbounded elements.

Die Psoriasis-Arthritis (PsA) gehört zu den chronisch entzündlichen Gelenkerkrankungen. Trotz zahlreicher versorgungswissenschaftlicher Studien in Deutschland liegen zur pharmazeutischen Versorgungssituation von PsA-Patienten bisher kaum aktuelle Ergebnisse vor. Mit Hilfe einer systematischen Literaturrecherche sowie anhand von Routinedaten der Allgemeinen Ortskrankenkasse (AOK) Rheinland/Hamburg wird ein aktueller Überblick über die pharmazeutische Versorgung von PsA-Patienten in Deutschland gegeben. Selektiert wurden Versicherte aus dem ambulanten und stationären Bereich, die im 1. und 2. Quartal des Jahres 2014 die gesicherte Abrechnungsdiagnose Psoriasis-Arthritis L40.5+ aufwiesen. Anschließend wurden auf Basis dieser "vorab definierten" Kohorte die Arzneimitteldaten für 5 Jahre (01.01.2010-31.12.2014) abgerufen. Es konnten insgesamt n  =  3205 Versicherte (45 % männlich, 55 % weiblich) der AOK Rheinland/Hamburg mit einer gesicherten PsA-Diagnose selektiert werden. Das Durchschnittsalter betrug 58,9 Jahre. 53,7 % der PsA-Patienten wurden mit systemischen PsA-relevanten Arzneimitteln versorgt. Nichtsteroidale Antirheumatika (NSAR) wurden am häufigsten verordnet, gefolgt von systemischen Glucocorticoiden. Von den selektierten PsA-Patienten, die eine Systemtherapie erhielten, wurden 72,1 % mittels einer Disease-modifying-antirheumatic-Drug (DMARD)-Monotherapie behandelt, gefolgt von der Kombinationstherapie aus DMARDs und Biologika (20,9 %). Die pharmakologische Therapie der PsA muss eine Gewährleistung zwischen adäquater Versorgung der PsA mit Verhinderung der Krankheitsprogression und ökonomischer Verantwortung darstellen. © 2018 Deutsche Dermatologische Gesellschaft (DDG).

Dabei demonstriert sie anhand von zentralen Figuren der weißen Frauenbewegung deren ambivalente Positionen, die oftmals für progressive Inhalte wie das Eintreten für Frauenrechte stehen, gleichzeitig aber dann Anliegen von African Americans nicht artikulieren oder gar zum Schweigen bringen. Ebenso zeigt Dietze mithilfe von Texten einiger schwarzer Autor_innen sowie anhand berühmter Gerichtsprozesse, dass schwarze Emanzipation nicht notwendigerweise mit feministischen Positionen einhergehen musste, sondern sich vielmehr eine Konkurrenzsituation zwischen Race und Gender entspann.

2010-01-01

Tundra Swan Cygnus columbianus columbinanus phenology and behaviour at the Eel River delta and southern Humboldt Bay in northern California, USA, is described. Counts made each January from 1963 onwards peaked at 1,502 swans in 1988. Monthly counts recorded during the 2006/07 and 2008/09 winters peaked in February, at 1,033 and 772 swans respectively. Swans roosted on ephemeral ponds at the Humboldt Bay National Wildlife Refuge, on ephemeral ponds within grassland pastures in the vicinity of the Refuge, and perhaps also used the Eel River as a roost. Flights between Refuge roosts and the pastures and ponds occurred in the two hours after sunrise and before dark. In winters 2008/09 and 2009/10, the percentage of cygnets in the flocks was 10.6% and 21.4% respectively, and increased to =31% cygnets each year after most swans had departed from the area in March. Average brood size in 2009/10 was 2.1 cygnets. Daily activities consisted of foraging (44.9% of activities recorded), comfort behaviour (22.1%), locomotion (16.2%) and vigilance (15.5%). Eight neck-collared swans identified in the wintering flock were marked at four locations in different parts of Alaska, up to 1,300 km apart.

Historic mills and mill tailings as potential sources of contamination in and near the Humboldt River basin, northern Nevada. Chapter D.

Science.gov (United States)

Nash, J. Thomas; Stillings, Lisa L.

2003-01-01

Reconnaissance field studies of 40 mining districts in and near the Humboldt River basin have identified 83 mills and associated tailings impoundments and several other kinds of mineral-processing facilities (smelters, mercury retorts, heap-leach pads) related to historic mining. The majority of the mills and tailings sites are not recorded in the literature. All tailings impoundments show evidence of substantial amounts of erosion. At least 11 tailings dams were breached by flood waters, carrying fluvial tailings 1 to 15 km down canyons and across alluvial fans. Most of the tailings sites are dry most of the year, but some are near streams. Tailings that are wet for part of the year do not appear to be reacting significantly with those waters because physical factors such as clay layers and hard-pan cement appear to limit permeability and release of metals to surface waters. The major impact of mill tailings on surface- water quality may be brief flushes of runoff during storm events that carry acid and metals released from soluble mineral crusts. Small ephemeral ponds and puddles that tend to collect in trenches and low areas on tailings impoundments tend to be acidic and extremely enriched in metals, in part through cycles of evaporation. Ponded water that is rich in salts and metals could be acutely toxic to unsuspecting animals. Rare extreme storms have the potential to cause catastrophic failure of tailings impoundments, carry away metals in stormwaters, and transport tailings as debris flows for 1 to 15 km. In most situations these stormwaters and transported tailings could impact wildlife but probably would impact few or no people or domes-tic water wells. Because all identified historic tailings sites are several kilometers or more from the Humboldt River and major tributaries, tailings probably have no measurable impact on water quality in the main stem of the Humboldt River.

Wilhelm Reich's self-censorship after his arrest as an enemy alien: the chilling effect of an illegal imprisonment.

Science.gov (United States)

Bennett, Philip W

2014-04-01

After discussing Wilhelm Reich's place in psychoanalysis, the article explores his arrest as an 'enemy alien' in December 1941. Reich's emotional responses to his imprisonment (which was illegal and which lasted nearly a month) are explored. A number of scholars have suggested that many European radical psychoanalysts refrained from sharing their former political ideas once they emigrated to the United States. Following a brief discussion of this pattern of 'silencing,' it is argued that Reich's withholding certain documents from publication was due to a self-imposed censorship, motivated in part by the fear of further governmental interference with his life and work. This fear, however, did not extend to his discussion of his newly developed theory of orgone energy. Copyright © 2014 Institute of Psychoanalysis.

Clarifying the link between von Neumann and thermodynamic entropies

Science.gov (United States)

Deville, Alain; Deville, Yannick

2013-01-01

The state of a quantum system being described by a density operator ρ, quantum statistical mechanics calls the quantity - kTr( ρln ρ), introduced by von Neumann, its von Neumann or statistical entropy. A 1999 Shenker's paper initiated a debate about its link with the entropy of phenomenological thermodynamics. Referring to Gibbs's and von Neumann's founding texts, we replace von Neumann's 1932 contribution in its historical context, after Gibbs's 1902 treatise and before the creation of the information entropy concept, which places boundaries into the debate. Reexamining von Neumann's reasoning, we stress that the part of his reasoning implied in the debate mainly uses thermodynamics, not quantum mechanics, and identify two implicit postulates. We thoroughly examine Shenker's and ensuing papers, insisting upon the presence of open thermodynamical subsystems, imposing us the use of the chemical potential concept. We briefly mention Landau's approach to the quantum entropy. On the whole, it is shown that von Neumann's viewpoint is right, and why Shenker's claim that von Neumann entropy "is not the quantum-mechanical correlate of thermodynamic entropy" can't be retained.

›All for nothing?‹. Die symbolische Darstellungs- und Erkenntnisform als philosophische und literaturtheoretische Herausforderung

Falk Bornmüller

2013-05-01

Full Text Available Literaturwissenschaft und Philosophie sehen sich gleichermaßen mit der Frage konfrontiert, wie mit dem Erkenntnismedium Literatur umgegangen und wie es in das eigene Erkenntnisinteresse integriert werden kann. Dabei ist das epistemologische Verhältnis von Literatur und Philosophie nicht etwa als ein streng dichotomisches zu verstehen, das sich auf die Formel propositional vs. nicht-propositional reduzieren lässt. Vielmehr ist ein erkenntnistheoretischer Gehalt von Literatur anzunehmen, dem eine binäre Betrachtungsweise nicht gerecht wird. Anhand zentraler Stellen in Shakespeares »Hamlet« und Goethes »Wilhelm Meisters Lehrjahre« wird die »symbolische Darstellungs- und Erkenntnisform« der Literatur als ein Akt der Erkenntnis, als ein nachvollziehendes Verstehen herausgearbeitet.

Johann Wilhelm Hittorf and the material culture of nineteenth-century gas discharge research.

Science.gov (United States)

Müller, Falk

2011-06-01

In the second half of the nineteenth century, gas discharge research was transformed from a playful and fragmented field into a new branch of physical science and technology. From the 1850s onwards, several technical innovations-powerful high-voltage supplies, the enhancement of glass-blowing skills, or the introduction of mercury air-pumps- allowed for a major extension of experimental practices and expansion of the phenomenological field. Gas discharge tubes served as containers in which resources from various disciplinary contexts could be brought together; along with the experimental apparatus built around them the tubes developed into increasingly complex interfaces mediating between the human senses and the micro-world. The focus of the following paper will be on the physicist and chemist Johann Wilhelm Hittorf (1824-1914), his educational background and his attempts to understand gaseous conduction as a process of interaction between electrical energy and matter. Hittorf started a long-term project in gas discharge research in the early 1860s. In his research he tried to combine a morphological exploration of gas discharge phenomena-aiming at the experimental production of a coherent phenomenological manifold--with the definition and precise measurements of physical properties.

El Niño and similar perturbation effects on the benthos of the Humboldt, California, and Benguela Current upwelling ecosystems

To a certain degree, Eastern Boundary Current (EBC) ecosystems are similar: Cold bottom water from moderate depths, rich in nutrients, is transported to the euphotic zone by a combination of trade winds, Coriolis force and Ekman transport. The resultant high primary production fuels a rich secondary production in the upper pelagic and nearshore zones, but where O2 exchange is restricted, it creates oxygen minimum zones (OMZs) at shelf and upper slope (Humboldt and Benguela Current) or slope depths (California Current). These hypoxic zones host a specifically adapted, small macro- and meiofauna together with giant sulphur bacteria that use nitrate to oxydise H2S. In all EBC, small polychaetes, large nematodes and other opportunistic benthic species have adapted to the hypoxic conditions and co-exist with sulphur bacteria, which seem to be particularly dominant off Peru and Chile. However, a massive reduction of macrobenthos occurs in the core of the OMZ. In the Humboldt Current area the OMZ ranges between immigrants. The autochthonous benthic fauna emigrates to deeper water or poleward, or suffers mortality. However, some local macrofaunal species experience important population proliferations, presumably due to improved oxygenation (in the southern hemisphere), higher temperature tolerance, reduced competition or the capability to use different food. Both these negative and positive effects of El Niño influence local artisanal fisheries and the livelihood of coastal populations. In the Humboldt Current system the hypoxic seafloor at outer shelf depths receives important flushing from the equatorial zone, causing havoc on the sulphur bacteria mats and immediate recolonisation of the sediments by mega- and macrofauna. Conversely, off California, the intruding equatorial water masses appear to have lower oxygen than ambient waters, and may cause oxygen deficiency at upper slope depths. Effects of this change have not been studied in detail, although shrimp and other

Albert Reder von Schellmann (1826-1904) was an important syphilidologist of the Vienna Medical School in the second half of the nineteenth century. He went in for the dualistic concept of the origin of syphilis and ulcer caused by soft chancre. In 1870 - Reder became head of a third dermato-syphilidologic department in the "Josephinum" in Vienna, where military surgeons got their medical education. At the same time the two full professorships of dermatosyphilidology in the Vienna General Hospital were held by Ferdinand von Hebra (1816-1880) and Carl Ludwig Sigmund von Ilanor (1810-1883).

Die Rolle von RANK-Ligand und Osteoprotegerin bei Osteoporose

Hofbauer LC

Full Text Available Receptor activator of nuclear factor (NF- κB ligand (RANKL, sein zellulärer Rezeptor RANK und der Decoy-Rezeptor Osteoprotegerin (OPG stellen ein essentielles Zytokinsystem für die Zellbiologie von Osteoklasten dar. Verschiedene Untersuchungen belegen die Bedeutung von Störungen des OPG/RANKL/RANK-Systems bei der Pathogenese metabolischer Knochenerkrankungen. In dieser Arbeit werden die wichtigsten Störungen des OPG/RANKL/RANK-Systems bei verschiedenen Osteoporoseformen dargestellt. Östrogenrezeptor- (ER- Agonisten wie 17 β-Östradiol, Raloxifen und Genistein stimulieren die osteoblastäre Produktion von OPG durch Aktivierung von ER- α in vitro, während Lymphozyten von Patientinnen mit Östrogenmangel RANKL überexprimieren. Die parenterale Gabe von OPG vermag den mit Östrogenmangel assoziierten Knochenverlust im Tiermodell und in einer kleineren klinischen Studie zu verhindern. Glukokortikoide und Immunsuppressiva steigern gleichzeitig die RANKL-Expression und hemmen die OPG-Produktion in osteoblastären Zellen in vitro. Glukokortikoide sind auch in vivo imstande, die OPG-Serumspiegel deutlich zu reduzieren. Dagegen hemmen biomechanische Reize in vitro die RANKL-Produktion und steigern die OPG-Produktion. Ein Fehlen dieser biomechanischen Reize bei längerer Immobilisierung kann daher den RANKL/OPG-Quotienten steigern, während die tierexperimentelle Immobilisierungs-Osteoporose durch die parenterale Gabe von OPG gemildert werden kann.

An eighteen-month-old female Humboldt penguin (Spheniscus humboldti) that was 50 cm in length and 4.5 kg in weight was presented with anorexia and vomiting. The hematological and blood biochemical profiles revealed no remarkable findings, and no Salmonella, Shigella or Vibrio spp. were isolated from the fecal culture. However, radiographic imaging revealed a long linear foreign body presenting from the lower esophagus to the stomach. To retrieve this foreign body, flexible endoscopic extraction was performed using flexible rat tooth grasping forceps. A long bamboo stick (29 × 1 cm) was removed from the stomach, and the penguin fully recovered.

Politische Bildung im Kontext von Regierung, Unterricht und Zucht

2014-02-01

Full Text Available Johann Friedrich Herbart (1776-1841 gilt als der Begründer der wissenschaftlichen Pädagogik. In diesem Beitrag wird zu zeigen versucht, dass Herbart die Unterstützung politischer Bildung als eine Aufgabe von Regierung, Unterricht und Zucht bestimmt und in seinem Werk wichtige „Bausteine“ für eine Theorie der politischen Bildung unter den Bedingungen von Erziehung vorlegt hat. Nach Herbart ist das politische Selbst- und Weltverhältnis auf Sachverhalte bezogen, die nicht nur die Lebensführung einzelner Menschen, sondern die Lebensführung einer Mehrzahl von Menschen betreffen. Nicht das Zusammenleben von Menschen generell ist jedoch Orientierungsgesichtspunkt des politischen Selbst- und Weltverhältnisses, sondern nur das problematisch gewordene Zusammenleben. Politik ergibt sich nach Herbart aus einem Konflikt hinsichtlich der Frage, wie das Zusammenleben von Menschen geregelt sein sollte. Während die Regierung lediglich mittelbar einen Beitrag zur politischen Bildung leistet, indem sie die Voraussetzungen für Unterricht und Zucht bereitstellt, fungieren die beiden zuletzt genannten Formen von Erziehung als die eigentlichen Medien, in denen die politische Bildung im Sinne Herbarts ihren Ort hat.

Baron von Zach's business relations with the Munich entrepreneur Joseph von Utzschneider (German Title: Geschäftsbeziehungen des Barons von Zach zu dem Münchner Unternehmer Joseph von Utzschneider)

Science.gov (United States)

Schneider, Ivo

The relationship between the astronomer von Zach on the one side and the entrepreneur Joseph von Utzschneider and his partner Georg von Reichenbach on the other dates presumably from the year 1807 when Zach spent two months in Munich. Already in the same year Zach had ordered an instrument for himself and began to solicit business for the institute of Reichenbach, Utzschneider, and Liebherr, which was founded in 1804. One of the clients canvassed by Zach was the director of the observatory in Naples Zuccari. Zuccari had ordered the whole equipment for the new observatory from this institute in 1813. The instruments for Naples, which were completed in 1814, were sent accompanied by Reichenbach by land and sea to their destination where Reichenbach supervised their setup. At that time Reichenbach had separated from Utzschneider who kept the optical institute in Benediktbeuern with his new partner Joseph von Fraunhofer whereas Reichenbach became owner of the mathematical-mechanical institute in Munich. For personal and economical reasons Utzschneider began soon after to produce not only optical glass but also optical devices similar to those offered by Reichenbach. As soon as two institutes in Munich competed against each other on the market for sophisticated geodetical and astronomical instruments Zach sided with Utzschneider. Zach's main professional argument for this decision was that both competitors got the optical glass for their instruments from Utzschneider's optical institute in Benediktbeuern. This meant that Utzschneider had first choice and so the optical part of his instruments could be considered as better than that of Reichenbach`s instruments. Zach's role as an agent in Italy and France for the sale of products coming from Utzschneider's manufactories is highlighted by three of Zach's letters to Utzschneider from 1817 and 1818, two of which are reproduced here for the first time.

John von Neumann selected letters

CERN Document Server

2005-01-01

John von Neuman was perhaps the most influential mathematician of the twentieth century, especially if his broad influence outside mathematics is included. Not only did he contribute to almost all branches of mathematics and created new fields, but he also changed post-World War II history with his work on the design of computers and with being a sought-after technical advisor to many figures in the U.S. military-political establishment in the 1940s and 1950s. The present volume is the first substantial collection of (previously mainly unpublished) letters written by von Neumann to colleagues, friends, government officials, and others. The letters give us a glimpse of the thinking of John von Neumann about mathematics, physics, computer science, science management, education, consulting, politics, and war. Readers of quite diverse backgrounds will find much of interest in this fascinating first-hand look at one of the towering figures of twentieth century science.

Full Text Available Article in Spanish, Abstracts in English and Spanish.As it is well known, Humboldt and Bonpland ended their almost five-years-journey throughout the American continent with a short but intense stay of nearly three months in the USA.As it has already been studied in a previous paper (‘HiN’ nº 3, 2001, Humboldt’s political and economical thesis predicted the role and the place that would most probably correspond to the newly born American nations within the new post-Napoleonic world order.Afterward, Humboldt explicitly stated that not only the future but the present of the USA seemed very different to the one of the Latin American countries due to the many ethnic, social and cultural barriers, and specially to the many historical ‘vices’ that these had inherited from the colony. This conviction was shared with other ‘illustrated’ German thinkers of his time, such as G.F. Hegel, who thought that after the full consummation of the Iberoamerican independence from Europe a confrontation, even military, will be unavoidable and even necessary between the North and the South of the America as precondition for the rebirthing of the ‘idea’, ‘reason’ and ‘spirit’ into the ‘new world’; it is, as precondition for the continuity of ‘History’; in other words, for avoiding the ‘end of History’. After 200 years of a complex and difficult coexistence between the USA and the rest of the continent, and after at least two failures of Iberoamerica to achieve a full reinsertion within the Western politics, culture and economy, the USA, having been a super world power for several decades, have offered, and even forced, a great continental alliance (‘ALCA ’that will lead in, a very short term (2005, to a unique and preferential continental market and, in some way, to a unique American economic culture. One of the many questions that arises about such a challenge is if the Iberoamerican countries have yet been able to overcome

Diagnosis and management of von Willebrand disease: guidelines for primary care.

Science.gov (United States)

Yawn, Barbara; Nichols, William L; Rick, Margaret E

2009-12-01

Von Willebrand disease is an inherited condition characterized by deficiency of von Willebrand factor, which is essential in hemostasis. The National Heart, Lung, and Blood Institute has released new evidence-based guidelines for the diagnosis and management of the disease. There are three major subtypes of von Willebrand disease, classified as partial quantitative deficiency (low levels) of von Willebrand factor (type 1), qualitative deficiency (type 2), or virtually complete deficiency (type 3). Diagnosis is usually made by reviewing the patient's personal and family history of bleeding and by clinical evaluation for more common reasons for bleeding, supplemented with laboratory tests. Assessment may be used to determine bleeding risk before surgery and other invasive procedures, and to diagnose reasons for unexplained hemorrhaging. Von Willebrand factor levels of 30 IU per dL or lower are required for the definite diagnosis of inherited von Willebrand disease. Persons with levels of 30 to 50 IU per dL may not have the disease, but may need agents to increase von Willebrand factor levels during invasive procedures or childbirth. Treatment is tailored to the subtype of the disease: increasing plasma concentration of von Willebrand factor by releasing endogenous stores with desmopressin or replacing nonexistent or ineffective von Willebrand factor by using human plasma-derived, viral-inactivated concentrates; treatment is often combined with hemostatic agents that have mechanisms other than increasing von Willebrand factor. Regular prophylaxis is seldom required, and treatment is initiated before planned invasive procedures or in response to bleeding.

"Cosmomorphistic geometry" in the unconscious geometry of Johannes Kepler

Adam, Adolf

Some mathematical aspects of the Music theory by Johannes Kepler are discussed, paying a special attention to the book "De harmonice mundi". Other scientists interested in Music theory are mentioned throughout the paper: The Pythagorean school, Klaudios Ptolemaios, Leonard Euler, Gottfried Wilhelm Leibniz, Christian von Goldbach, Hermann Ludwig Ferdinand von Helmholz, Karl Friedrich Gauss. The relation with the ancient chinese schools of cosmography has been discussed: From the the Pythagorean to the ancient Chinese schools of cosmography we find arithmo-geometrical applications of numbers which are emblematic, hold meaning or represent the essence of things, the author writes. It was Johannes Kepler who taught us this "transconstructive method" of forming classical and ancient begginings of structuralistic thinking into a system from which deductions can readily be made.

Ausgangspunkt ist die Beobachtung, daß Beschreibungen von Nachfragen nur in geringer Zahl vorliegen, aus sehr unterschiedlichen Bereichen stammen (Konversationsanalyse, grammatische Beschreibungen von Fragen und Literatur zu Echofragen und sich Beschreibungen von Nachfrageformen sowie Nachfragefunktionen und die jeweils unterstellten Form-Funktions-Bezüge - auch in den einzelnen Bereichen - vielfach widersprechen. Vor diesem Hintergrund ist zentales Anliegen der Untersuchung, einen übergeordneten Analyserahmen für die Befassung mit Frageformen und Fragefunktionen zu entwickeln, der die Beschreibung von Nachfragen in einer allgemeineren Beschreibung von Interrogationen verortet. Das Besondere von Nachfragen wird darin gesehen, daß es sich um Interrogationen handelt, die auf andere sprachliche Äußerungen Bezug nehmen.

The report is aimed at collecting and documenting the state of the art and the extensive know how of experts and pipeline operators with regard to judging the structural integrity of pipelines. In order to assess the actual mechanical strength of pipelines based on measurement results obtained by inspection pigs, guidance is given for future processing, which eventually can be used as a basis for an industry standard. A literature study of the commercially available types of inspection pigs describes and synoptically lists the respective pros and cons. In essence the report comprises besides check lists of operating data for the pipeline and the pig runs mainly the evaluation of defects and respective calculating procedures. Included are recommendations regarding maintenance planning, verification of defects as well as repetition of pig runs. (orig.)

A bicategorical approach to Morita equivalence for von Neumann algebras

International Nuclear Information System (INIS)

Brouwer, R. M.

2003-01-01

We relate Morita equivalence for von Neumann algebras to the ''Connes fusion'' tensor product between correspondences. In the purely algebraic setting, it is well known that rings are Morita equivalent if they are equivalent objects in a bicategory whose 1-cells are bimodules. We present a similar result for von Neumann algebras. We show that von Neumann algebras form a bicategory, having Connes's correspondences as 1-morphisms, and (bounded) intertwiners as 2-morphisms. Further, we prove that two von Neumann algebras are Morita equivalent iff they are equivalent objects in the bicategory. The proofs make extensive use of the Tomita-Takesaki modular theory

Pure Jauch-Piron states on von Neumann algebras

International Nuclear Information System (INIS)

Hamhalter, J.

1993-01-01

We study Jauch-Piron states and two-valued measures on von Neumann algebra. We prove as the main result that, under some set-theoretical assumption, a pure state of a von Neumann algebra A not containing a central abelian portion is Jauch-Piron if and only if it is σ-additive. Moreover, we show that this result holds for type I factor indenpendently on the set-theoretical axiomatics. As a consequence we obtain a lucid characterization of pure Jauch-Piron states on von Neumann algebras acting on a Hilbert space with real-nonmeasurable dimension (this can be viewed as a generalization of the paper). We also characterize the von Neumann algebras whose logic of projections is Jauch-Piron. Finally, we prove that every two-valued measure on the projection logic of A, where A contains no type I 2 central portion, has to be concentrated at an abelian direct summand of A. (orig.)

Marshall Center Director Dr. Wernher Von Braun is pictured with Walt Disney during a visit to the Marshall Space Flight Center in 1954. In the 1950s, Dr. Von Braun while working in California on the Saturn project, also worked with Disney studios as a technical director in making three films about Space Exploration for television. Disney's tour of Marshall in 1965 was Von Braun's hope for a renewed public interest in the future of the Space Program at NASA.

[The history of the Kaiser Wilhelm Society during the Third Reich. Interim reports of the president's commission of the Max Planck Society].

In 1997 the Max Planck Society set up a presidential commission to do research on the historical development of its precursor organization, the Kaiser Wilhelm Society (KWG), during the Third Reich. This paper presents some of the important results given in the interim reports of this commission that are relevant to psychiatry. It focuses on brain research, anthropology, psychiatric genetics, and the role of the well-known biochemist Adolf Butenandt. In general, the interim reports reflect the numerous links between the biomedical research of the KWG and the institutions of the National Socialist (Nazi) state. However, they do not yet allow a final historical assessment as to the complex situation of this field of research during National Socialism.

Physiological optics, cognition and emotion: a novel look at the early work of Wilhelm Wundt.

Science.gov (United States)

Wassmann, Claudia

2009-04-01

The German physiologist Wilhelm Wundt, who later founded experimental psychology, arguably developed the first modern scientific conception of emotion. In the first edition of Vorlesungen über die Menschen- und Thierseele (Lectures on human and animal psychology), which was published in 1863, Wundt tried to establish that emotions were essential parts of rational thought. In fact, he considered them unconscious steps of decision-making that were implied in all processes of conscious thought. His early work deserves attention not only because it is the attempt to conceptualize cognition and emotion strictly from a neural point of view but also because it represents the very foundation of the debate about the nature of emotion that revolved around William James' theory of emotion during the 1890s. However, this aspect of his work is little known because scholars who have analyzed Wundt's work focused on his late career. Furthermore, historical analysis interpreted Wundt's work within a philosophical framework, rather than placing it in the context of German medical and physiological research in which it belongs. In addition, Wundt's early works are hardly available to an English speaking audience because they were never translated.

Influence of thermal discharges on the distribution of macroflora and fauna. Humboldt Bay Nuclear Power Plant, California

International Nuclear Information System (INIS)

Adams, J.R.

1975-01-01

Populations of benthic and epifaunal macro-organisms living in the area influenced by the thermal discharge of the steam-electric power plant at Humboldt Bay, California, were analyzed in 1971 and 1972 to determine if differences in distribution could be attributed to the effluent. Relicated benthic samples were collected with a Ponar grab at 20 stations in the bay and at 4 stations in the canals leading to and from the power plant. Comparisons of epifaunal plants and animals in a rocky intertidal zone were made at 13 permanent transects spaced at various distances on either side of the discharge. Species richness in the intertidal was positively correlated with increased temperature in 13 percent of the possible combinations of tide level and diversity. Individual species were positively correlated with increased temperatures for 19 percent of the plant comparisons, and for 16.3 percent of the animal comparisons. Comparisons of populations of individual species in the heated intertidal zone with those in a control zone indicated differences in 26.2 percent of the plant surveys, and 23.2 percent of the animal surveys. Differences were positively related to the increased temperature in 90.5 percent of the comparisons. Proportions of eurythermal plants or animals in the heated areas of the intertidal zone did not differ significantly from proportions in other areas in 4 different survey periods. With the possible exception of one species, there was no conclusive evidence that any of the 132 species found in the intertidal area at Humboldt Bay was eliminated from the heated area surrounding the discharge of the power plant

Genomic features of "Candidatus Venteria ishoeyi", a new sulfur-oxidizing macrobacterium from the Humboldt Sulfuretum off Chile.

Full Text Available The Humboldt Sulfuretum (HS, in the productive Humboldt Eastern Boundary Current Upwelling Ecosystem, extends under the hypoxic waters of the Peru-Chile Undercurrent (ca. 6°S and ca. 36°S. Studies show that primeval sulfuretums held diverse prokaryotic life, and, while rare today, still sustain species-rich giant sulfur-oxidizing bacterial communities. We here present the genomic features of a new bacteria of the HS, "Candidatus Venteria ishoeyi" ("Ca. V. ishoeyi" in the family Thiotrichaceae.Three identical filaments were micro-manipulated from reduced sediments collected off central Chile; their DNA was extracted, amplified, and sequenced by a Roche 454 GS FLX platform. Using three sequenced libraries and through de novo genome assembly, a draft genome of 5.7 Mbp, 495 scaffolds, and a N50 of 70 kbp, was obtained. The 16S rRNA gene phylogenetic analysis showed that "Ca. V. ishoeyi" is related to non-vacuolate forms presently known as Beggiatoa or Beggiatoa-like forms. The complete set of genes involved in respiratory nitrate-reduction to dinitrogen was identified in "Ca. V. ishoeyi"; including genes likely leading to ammonification. As expected, the sulfur-oxidation pathway reported for other sulfur-oxidizing bacteria were deduced and also, key inorganic and organic carbon acquisition related genes were identified. Unexpectedly, the genome of "Ca. V. ishoeyi" contained numerous CRISPR repeats and an I-F CRISPR-Cas type system gene coding array. Findings further show that, as a member of an eons-old marine ecosystem, "Ca. V. ishoeyi" contains the needed metabolic plasticity for life in an increasingly oxygenated and variable ocean.

Von Neumann's impossibility proof: Mathematics in the service of rhetorics

Science.gov (United States)

Dieks, Dennis

2017-11-01

According to what has become a standard history of quantum mechanics, in 1932 von Neumann persuaded the physics community that hidden variables are impossible as a matter of principle, after which leading proponents of the Copenhagen interpretation put the situation to good use by arguing that the completeness of quantum mechanics was undeniable. This state of affairs lasted, so the story continues, until Bell in 1966 exposed von Neumann's proof as obviously wrong. The realization that von Neumann's proof was fallacious then rehabilitated hidden variables and made serious foundational research possible again. It is often added in recent accounts that von Neumann's error had been spotted almost immediately by Grete Hermann, but that her discovery was of no effect due to the dominant Copenhagen Zeitgeist. We shall attempt to tell a story that is more historically accurate and less ideologically charged. Most importantly, von Neumann never claimed to have shown the impossibility of hidden variables tout court, but argued that hidden-variable theories must possess a structure that deviates fundamentally from that of quantum mechanics. Both Hermann and Bell appear to have missed this point; moreover, both raised unjustified technical objections to the proof. Von Neumann's argument was basically that hidden-variables schemes must violate the ;quantum principle; that physical quantities are to be represented by operators in a Hilbert space. As a consequence, hidden-variables schemes, though possible in principle, necessarily exhibit a certain kind of contextuality. As we shall illustrate, early reactions to Bohm's theory are in agreement with this account. Leading physicists pointed out that Bohm's theory has the strange feature that pre-existing particle properties do not generally reveal themselves in measurements, in accordance with von Neumann's result. They did not conclude that the ;impossible was done; and that von Neumann had been shown wrong.

Sources of Wilhelm Johannsen's genotype theory.

Science.gov (United States)

Roll-Hansen, Nils

2009-01-01

This paper describes the historical background and early formation of Wilhelm Johannsen's distinction between genotype and phenotype. It is argued that contrary to a widely accepted interpretation (For instance, W. Provine, 1971. The Origins of Theoretical Population Genetics. Chicago: The University of Chicago Press; Mayr, 1973; F. B. Churchill, 1974. Journal of the History of Biology 7: 5-30; E. Mayr, 1982. The Growth of Biological Thought, Cambridge: Harvard University Press; J. Sapp, 2003. Genesis. The Evolution of Biology. New York: Oxford University Press) his concepts referred primarily to properties of individual organisms and not to statistical averages. Johannsen's concept of genotype was derived from the idea of species in the tradition of biological systematics from Linnaeus to de Vries: An individual belonged to a group - species, subspecies, elementary species - by representing a certain underlying type (S. Müller-Wille and V. Orel, 2007. Annals of Science 64: 171-215). Johannsen sharpened this idea theoretically in the light of recent biological discoveries, not least those of cytology. He tested and confirmed it experimentally combining the methods of biometry, as developed by Francis Galton, with the individual selection method and pedigree analysis, as developed for instance by Louis Vilmorin. The term "genotype" was introduced in W. Johannsen's 1909 (Elemente der Exakten Erblichkeitslehre. Jena: Gustav Fischer) treatise, but the idea of a stable underlying biological "type" distinct from observable properties was the core idea of his classical bean selection experiment published 6 years earlier (W. Johannsen, 1903. Ueber Erblichkeit in Populationen und reinen Linien. Eine Beitrag zur Beleuchtung schwebender Selektionsfragen, Jena: Gustav Fischer, pp. 58-59). The individual ontological foundation of population analysis was a self-evident presupposition in Johannsen's studies of heredity in populations from their start in the early 1890s till his

Full Text Available Seit einigen Jahren ist die Analyse von EEG-Signalen bei Epilepsie Gegenstand zahlreicher wissenschaftlicher Arbeiten; Zielvorstellung ist dabei die Entwicklung von Verfahren zur Erkennung eines möglichen Voranfallszustandes. Im Vordergrund steht beispielsweise die Approximation einer so genannten effektiven Korrelationsdimension, die Bestimmung der maximalen Lyapunov-Exponenten, Detektionsverfahren für Muster bei Zellularen Nichtlinearen Netzwerken, die Bestimmung der mittleren Phasenkohärenz und Verfahren zur nichtlinearen Prädiktion von EEG-Signalen. Trotz umfangreicher Bemühungen kann bis heute eine Erkennung von Anfallsvorboten mit einer Sensitivität und Spezifität, die eine automatisierte Anfallsvorhersage ermöglichen würde, noch nicht durchgeführt werden. In diesem Beitrag werden neue Ergebnisse zur Prädiktion von EEG-Signalen bei Epilepsie vorgestellt. Dabei werden Signale, welche mittels intrakranieller electrocorticographischer (ECoG und stereoelectroencephalographischer (SEEG Ableitungen registriert wurden, segmentweise analysiert. Unter der Annahme, dass sich Änderungen des Systems ,,Gehirn" als Änderungen im Prädiktor, d.h. in seinen Systemparametern widerspiegeln, könnte eine nähere Betrachtung der Prädiktoreigenschaften zu einer Erkennung von Anfallsvorboten führen.

Krause, Egon; Kalkmann, Ulrich

2013-05-01

In the Introduction the reader is referred back to the academic ceremonials held after Theodore von Kármán's death in Aachen in May 1963. His work as the first director of the Aerodynamisches Institut (Institute of Aerodynamics) of the RWTH Aachen University of Technology from 1913 on and his initiative to re-establish international cooperation after World War I, resulting in the International Union of Theoretical and Applied Mechanics (IUTAM), are commented on. The following chapter describes von Kármán's relation to his former teacher Ludwig Prandtl. Some of von Kármán's scientific contributions during his time in Aachen are briefly reviewed. Thereafter, his first contacts to the California Institute of Technology are covered. Finally, the scientific and political circumstances, which led to von Kármán's decision to leave Germany in the early thirties, are elucidated in some detail. The English translation of the titles of the Aachen papers is given in Appendix I.

Die beiden Institutsdirektoren am Anfang des 20sten Jahrhunderts waren Vertreter der allumfassenden Geologie des 19ten Jahrhunderts, während die beiden folgenden Direktoren eine Geologie ohne Paläontologie vertraten. Das führte zu einer Trennung der beiden Richtungen, und nach der III. Hochschulreform der DDR 1968 verblieb allein die sammlungsbezogene Paläontologie am Museum. Nach der Wiedervereinigung wurde ein Institut für Paläontologie mit biologischer Ausrichtung mit zwei Professuren, einer für Paläozoologie und einer für Paläobotanik, eingerichtet. The development of the Geologisch-Paläontologisches Institut und Museum of the Museum für Naturkunde at the Humboldt University (formerly Friedrich-Wilhelm-Universität in Berlin from a geology-paleontology institution to a pure paleontology institution is described. The first two directors of the department in the beginning of the 20th century, Prof, von Branca and Prof. Pompeckj, represented a 19th century concept of a geology, which included paleontology, even vertebrate paleontology as the crown jewel of geology. They fought sometimes vigorously against a separation of paleontology from geology. The next two directors. Prof. Stille and Prof, von Bubnoff, were the leading geologists in Germany; to be a student of Stille was a special trade mark in geology of Germany. They represented a geology centered on tectonics. The separation of paleontology as separate section was prepared.

Full Text Available Dieser Beitrag soll die Forschungslücke zur Darstellung von Behinderungen speziell im Kinderfilm im deutschsprachigen Raum füllen. Auf Basis einer neoformalistisch orientierten Filmanalyse nach Bordwell und Thompson (2008, wird anhand von drei Filmsequenzen eine mögliche Lesart des Kinderfilms "Heidi" (Marcus 2005 entwickelt, um die filmstilistische Darstellung der Gehbehinderung des Mädchens Klara zu untersuchen. Die Ergebnisse werden mit theoretischen Überlegungen zur Problematik der Begriffsbestimmung von Körperbehinderung sowie zur Mobilität und Selbstbestimmung von Menschen mit Körperbehinderungen in Bezug gesetzt. Dabei zeigt sich im Wesentlichen, dass im Kinderfilm "Heidi" (Marcus 2005 Klaras Gehbehinderung als 'heilbare Krankheit' und der Rollstuhl als Einschränkung von Mobilität begriffen wird. Außerdem unterliegt Klara aufgrund ihrer Körperbehinderung überwiegend der Fremdbestimmung von Erwachsenen. Zur Klärung wahrscheinlicher filmischer Bildungspotenziale werden die Ergebnisse schließlich anhand der von Jörissen und Marotzki (2009 entwickelten Orientierungsdimensionen "Wissens-, Handlungs-, Grenz- und Biographiebezug" diskutiert. This article aims to bridge a knowledge gap by showing ways of representing disabilities in the German children film genre. Using Bordwell and Thomson's (2008 neoformalistically orientated film analysis approach, the movie "Heidi" (Marcus 2005 is analysed. Bordwell and Thompson's (2008 method is applied to three sequences of "Heidi" in order to present an interpretation and to discuss the representation of Clara's walking impediment. The results are then associated with theoretical considerations regarding the mobility and self-determination of people with disabilities and problematic definitions of the term 'physical disability'. It is shown that characters in the children's film "Heidi" (Marcus 2005 regard Clara's walking impediment as a 'curable disease' and the wheelchair as a limitation

Wilhelm Osbahr, at the beginning of the 20th century, made an attempt to solve the problemof indicating the balance sheet values (the impact of balance sheet evaluation on the balance sheet items,from the point of view of an entrepreneur or business owner, at the same time clearly emphasizing the necessityto deal with the balance sheet structure through the prism of the objectives pursued by the company. Osbahrpostulated highlighting any changes occurring in the economic structure of the company and its components,which do not result directly from its operating activities, and so to present them in the position called “adjustments”.This article uses the deductive method supported by literature studies and a case study method. Theauthors using the case study method confirm the possibility of using the described balance sheet theory in thecurrent financial reporting based on actual data of the company ABC Ltd. They also show that a balance sheetwhich is presented according to the new reporting formula discloses new quality of information for the financialreporting users.

Investigation of partial oxidation of hydrogen sulfide for dry desulfurisation of fuel gases; Untersuchung der Partialoxidation von Schwefelwasserstoff zur Trockenentschwefelung von Brenngasen

Energy Technology Data Exchange (ETDEWEB)

Kliemczak, U.

2002-07-01

Three process variants for direct desulfurisation in the dry state of coal gasification gases by partial oxidation of H{sub 2}S were investigated in Prenflo conditions: 1. Heterogeneously catalyzed partial oxidation of H{sub 2}S on fly dust followed by sulfur deposition on the dust; 2. Non-catalyzed partial oxidation of H{sub 2}S in a homogeneous gaseous phase followed by sulfur deposition in a spray separator; 3. Heterogeneously catalyzed partial oxidation of H{sub 2}S in a fixed bed. The experiments were carried out in conditions similar to the crude gas conditions of slag bath gasification at SVZ Schwarze Pumpe. The fixed bed materials investigated were hearth furnace coke, Berl saddles, and an activated carbon developed specially for the investigations, Oxorbon CJ. The focus of the investigations was on the envisaged continuous operation of the process. [German] Im Rahmen der vorliegenden Arbeit wurde an einer zu diesem Zweck modifizierten Technikumsanlage die trockene Direktentschwefelung von Brenngasen aus der Kohlevergasung durch partielle Oxidation von H{sub 2}S untersucht. Im Vordergrund standen zwei Verfahrensvarianten, deren Eignung fuer die Bedingungen der Prenflo-Vergasung ueberprueft werden sollte: Variante 1: die heterogen katalysierte Partialoxidation von H{sub 2}S an Flugstaub mit anschliessender Schwefelabscheidung auf dem Staub und, Variante 2: die nichtkatalysierte Partialoxidation von H{sub 2}S in homogener Gasphase mit anschliessender Schwefelabscheidung in einem Spruehabscheider. Ausgehend von den Versuchsergebnissen der Verfahrensvarianten 1 und 2 wurde zusaetzlich als Verfahrensvariante 3 die heterogen katalysierte Partialoxidation von H{sub 2}S am Festbett untersucht. Diese Versuche orientierten sich an den Rohgasbedingungen der Schlackebadvergasung des SVZ Schwarze Pumpe. Als Festbettmaterialien kamen Herdofenkoks, Berlsaettel und eine, speziell fuer diese Verfahrensvariante entwickelte Aktivkohle Oxorbon CJ, zum Einsatz. Die Eignung des

The RCP method was designed as a residue-optimised alternative to the thermally optimised grate firing of residual wastes. Its technical realisation and development to market maturity took no more than 5 years. In the first process stage the waste is converted to high-carbon pyrolysis charcoal and high-rank gas in the absence of oxygen. In the second stage these substances are oxidised by addition of oxygen. The resulting temperature causes the non-combustible constituents of the slag to melt. In a third, optional, stage this molten slag can be liberated of (heavy) metals to such an extent that it can subsequently be used directly as additive for grinding. Further exhaust gas treatment is facilitated by the use of a circulatory fluidised-bed secondary combustion chamber. Despite the reduced flue gas volume and resultant higher pollutant concentrations in the crude gas, overall emissions are lower than in conventional plants. [Deutsch] Das reststoffoptimierte RCP Verfahren ist als Alternative zur thermisch optimierten Rostverbrennung von Restabfaellen konzipiert. In nur fuenf Jahren wurde das Verfahren technisch umgesetzt und zur Marktreife entwickelt. In einer ersten Stufe des Verfahrens wird der Abfall unter Luftabschluss in einen kohlenstoffreichen Pyrolysekoks und eine heizwertreiches Gas umgesetzt. Im zweiten Schritt werden diese Stoffe unter Zugabe von Sauerstoff oxidiert. Dabei treten Temperaturen auf, bei denen die nichtbrennbaren Bestandteile der Schlacke schmelzen. Optional wird diese Schmelzschlacke in einem dritten Schritt derart von (Schwer-) Metallen befreit, dass sie anschliessend direkt als Zement-Zumahlstoff eingesetzt werden kann. Die Nutzung der zirkulierenden Wirbelschicht - Nachbrennkammer zur Abgasbehandlung vereinfacht die weitergehende Abgasbehandlung. Trotz verringertem Rauchgasvolumen und damit hoeheren Schadstoffkonzentrationen im Rohgas werden die Gesamtemissionen gegenueber konventionellen Anlagen verringert. (orig./SR)

The impacts on human health and the natural environment of using natural gas, Diesel and petrol as fuels for city buses and passenger cars are compared in a Life Cycle Assessment. In addition to the burning of the fuels in the engines, this assessment also comprises the upstream processes of the fuel supply chain. Despite the increased energy demand of the vehicles, natural gas is associated with the lowest impacts overall for both city buses and passenger cars. The health impacts that can be avoided through the use of natural gas instead of Diesel or petrol thereby differ only weakly between the use of the vehicles in cities of various sizes within Germany. From the perspective of environmental protection, the market introduction of natural gas vehicles therefore does not need remain limited to large cities within agglomerated regions. (orig.) [German] Die Auswirkungen der Verwendung von Erdgas, Diesel und Benzin als Kraftstoffe fuer Stadtbusse und Pkw auf die menschliche Gesundheit und die natuerliche Umwelt werden in einer Oekobilanz verglichen. Diese umfasst neben der motorischen Verbrennung der Kraftstoffe auch die vorgelagerten Prozessketten der Kraftstoffbereitstellung. Sowohl fuer Stadtbusse als auch fuer Pkw schneidet Erdgas trotz eines energetischen Mehrbedarfes der Fahrzeuge insgesamt am guenstigsten ab. Die durch den Einsatz von Erdgas anstelle von Diesel oder Benzin vermeidbaren Gesundheitsschaeden unterscheiden sich dabei zwischen einem Einsatz der Fahrzeuge in Staedten verschiedener Groesse innerhalb von Deutschland nur wenig. Die Markteinfuehrung von Erdgasfahrzeugen muss also aus Sicht des Umweltschutzes nicht auf grosse Staedte in Ballungsgebieten beschraenkt bleiben. (orig.)

This is lecture on the historical development of modern virus research in Germany to introduce a symposium dedicated to Prof. Werner Schäfer, Tübingen, on the occasion of his 65th birthday. The author was set the task of relating from his memories the beginning of modern virus research in Germany. This research has, since 1936, essentially taken place in the Kaiser-Wilhelm/Max-Planck-Society and in 1954 led to the founding of the Max-Planck-Institute for Virus Research in Tübingen, an institute which to the present day owes its scientific reputation in considerable part to the activity of Werner Schäfer. Since the author personally experienced and participated in the Institute's development from 1936-1954, his remarks are predominantly influenced by personal recollections, which have been sharpended by a renewed study of old records in the 'Library and Archive of the History of the Max-Planck-Gesellschaft', Berlin-Dahlem.

El análisis amplía horizontes para la compresión de los mecanismos que articulan el entramado de significados de la película, donde Von Trier aporta una nueva visión del arquetipo de Medea uniéndola, a la tradición pictórica del Romanticismo. Una influencia que habita en las posteriores obras del director danés, donde el paisaje, la naturaleza, se erige en elemento catalizador de las pulsiones humanas, en su cómplice y testigo.This paper explores the way that Lars von Trier’s film recreates the stereotype of Medea. Using film analysis and based on cultural studies the article asks about the importance and potential power of cinema to recover the ancient myth and show their effects. The analysis expands horizons for the understanding of the mechanisms that link the network of meanings of the film, where the author offers a new vision of Medea's archetype attaching it to the pictorial tradition tied to the Romanticism. An influence that can be seen in the later works of Lars von Trier, where the landscape, the nature, stands as a catalyst of human drives, as his accomplice and witness.

Frohner R

2013-01-01

Full Text Available In vorausgegangenen Studien konnte gezeigt werden, dass eine Gesichtsklassifikation mittels Gesichtsphotographien zur Diagnostik von Akromegalie mit guten Ergebnissen eingesetzt werden kann. In diesem Artikel werden die grundlegende Vorgehensweise der Klassifikation mittels der Software FIDA erläutert sowie Optimierungsansätze mit dem Ziel diskutiert, diese Methode näher an den klinischen Einsatz zu bringen. Die Gesichtsklassifikation basiert auf „Knotenpunkten“, die verteilt über die jeweilige Frontal- und/oder Seitenansicht des Gesichts platziert werden und den so genannten „Graphen“ bilden. Mittels mathematischer Verfahren erfolgt eine Analyse der zugrunde liegenden Textur des Bildes sowie die Auswertung geometrischer Informationen. Untersucht wird, wie sich die Reduktion von als irrelevant eingestuften Knoten auf das Klassifikationsergebnis auswirkt. Ebenso wird untersucht, wie sich neu definierte Knoten, die die typischen morphologischen Veränderungen der akromegalen Erkrankung im Gesicht berücksichtigen, auf die Klassifizierungsergebnisse auswirken. Die interne Validierung erfolgt an einem Datenset bestehend aus 57 an Akromegalie erkrankten Probanden (29 weiblich, 28 männlich sowie 59 Kontrollen (29 weiblich, 30 männlich. Die externe Validierung wird an einer weiteren Stichprobe gemessen, die zum Zeitpunkt der Präsentation auf der Tagung der European Neuroendocrine Association 2012 in Wien 13 akromegale Patienten (7 weiblich, 6 männlich sowie 45 Kontrollen (25 weiblich, 20 männlich umfasste. Die Datenbank wird ständig durch neue Probanden aus verschiedenen Quellen erweitert. Erste Ergebnisse zeigen, dass die Verwendung von Graphen mit reduzierten Knoten und von neuen Sets von Knoten unter Einbeziehung typischer morphologischer Veränderungen des Gesichts die Klassifizierung weiter verbessert. Diese Ergebnisse ermutigen zu weiteren Untersuchungen an einer erweiterten Datenbank.

Es ergibt sich: 1. Das von MERTON bezeichnete "Kinoplasma" existiert nicht als solches, es handelt sich bei den von ihm dargestellten Protoplasmabildungen um kugelige, von den Spermiden abgeschnuerte Restkoerper nicht verwendeten Baumaterials, bestehend aus Protoplasma und einigen Mitochondrien. Sie werden von den Naehr- oder Bazalzellen phagozytiert. Der Ausdruck "Kinoplasma" kann nur fuer die submikroskopischen, geformten, faedigen Elemente des Cytoplasmas reserviert bleiben, die den geradlinigen Fall der uebrigen nicht geformten Komponenten bremst oder ablenkt; damit muss das Kinoplasma aber aus dem Begriff des Cytoplasmas herausgenommen werden, da es, wenn auch vermutlich reversibel, eine Differenzierung darstellt. 2. Der Spermienfaden wird von den Centriolen (Axialfilament und den Mitochondrien (zwei peripher gelegene Spiralfilamente, sowie einem Plasmamantel gebildet. 3. Nach Beendigung des Auswachsens der Spermiengeissel, die zu diesem Zeitpunkt nur aus dem Achsenfaden und dem Protoplasmazylinder besteht, setzt sich eine Protoplasmamasse vom Kopf in Richtung zum Geisselende in Bewegung. Sie fuehrt den Golgi-Koerper und sehr viele Mitochondrien mit sich. Aus diesen entwickeln sich Fibrillen, die sich zu den beiden Spiralfilamenten zusammenfuegen. Diese Masse entspricht der von MERTON in seiner Theorie als Kinoplasma bezeichneten Komponente. 4.

Fractal geometry is used in diverse research areas, being an useful tool in describing the mechanical behaviour of natural and man-made structures. In this paper, the structural behaviour of a von Koch cantilever beam is analyzed in the small deformations regime. Analytical recursive formulae for the strain energy scaling are derived, which have been found in good agreement with numerical simulations. Energy considerations suggest a peculiar scaling for the beam rigidity in order to prevent compliance divergence. The results are then extended to evaluate the stiffness matrix of a von Koch beam.

Common catabolic enzyme patterns in a microplankton community of the Humboldt Current System off northern and central-south Chile: Malate dehydrogenase activity as an index of water-column metabolism in an oxygen minimum zone

González, R. R.; Quiñones, R. A.

2009-07-01

An extensive subsurface oxygen minimum zone off northern and central-south Chile, associated with the Peru-Chile undercurrent, has important effects on the metabolism of the organisms inhabiting therein. Planktonic species deal with the hypoxic and anoxic environments by relying on biochemical as well as physiological processes related to their anaerobic metabolisms. Here we characterize, for the first time, the potential enzymatic activities involved in the aerobic and anaerobic energy production pathways of microplanktonic organisms (oxygen concentration and microplanktonic biomass in the oxygen minimum zone and adjacent areas of the Humboldt Current System water column. Our results demonstrate significant potential enzymatic activity of catabolic pathways in the oxygen minimum zone. Malate dehydrogenase had the highest oxidizing activity of nicotinamide adenine dinucleotide (reduced form) in the batch of catabolic enzymatic activities assayed, including potential pyruvate oxidoreductases activity, the electron transport system, and dissimilatory nitrate reductase. Malate dehydrogenase correlated significantly with almost all the enzymes analyzed within and above the oxygen minimum zone, and also with the oxygen concentration and microplankton biomass in the water column of the Humboldt Current System, especially in the oxygen minimum zone off Iquique. These results suggest a possible specific pattern for the catabolic activity of the microplanktonic realm associated with the oxygen minimum zone spread along the Humboldt Current System off Chile. We hypothesize that malate dehydrogenase activity could be an appropriate indicator of microplankton catabolism in the oxygen minimum zone and adjacent areas.

Let M be a von Neumann algebra of type II1 which is also a complemented subspace of B( H). We establish an algebraic criterion, which ensures that M is an injective von Neumann algebra. As a corollary we show that if M is a complemented factor of type II1 on a Hilbert space H, then M is injective...

Full Text Available The aim of this study is to present the possibilities of the practical application of Osbahr’s balance sheet theory assumptions, as one of many possible attempts to close the information gap in the financial reporting of the twenty-first century. Wilhelm Osbahr, at the beginning of the 20th century, made an attempt to solve the problem of indicating the balance sheet values (the impact of balance sheet evaluation on the balance sheet items, from the point of view of an entrepreneur or business owner, at the same time clearly emphasizing the necessity to deal with the balance sheet structure through the prism of the objectives pursued by the company. Osbahr postulated highlighting any changes occurring in the economic structure of the company and its components, which do not result directly from its operating activities, and so to present them in the position called “adjustments”. This article uses the deductive method supported by literature studies and a case study method. The authors using the case study method confirm the possibility of using the described balance sheet theory in the current financial reporting based on actual data of the company ABC Ltd. They also show that a balance sheet which is presented according to the new reporting formula discloses new quality of information for the financial reporting users.

Wilhelm Winkler (1842-1910) - a Thuringian private astronomer and maecenas

Science.gov (United States)

Weise, Wilfried; Dorschner, Johann; Schielicke, Reinhardt E.

Wilhelm Winkler was born in 1842 in Eisenberg, Thuringia, as the son of a lawyer. After attending the trading high school in Gera, Winkler worked as a merchant in Eisenberg, following in the footsteps of his grandfather. In 1875 he gave up this trade and devoted his time entirely to astronomy. Advised by Carl Bruhns, director of the Leipzig University Observatory, he established an observatory on his estate in Gohlis near Leipzig. From 1878 Winkler regularly observed sunspots; other fields of his observational interests were comets, occultations of stars by the Moon, and Jupiter's satellites. In 1887 he went to Jena, where he contacted Ernst Abbe, who was the head of the Jena observatory, too. For some years, Winkler's instruments were used in the new observatory erected by Abbe, which replaced the old Ducal Observatory of the Goethe era. Winkler donated the precision pendulum clock and some other instruments to this observatory. He also offered his observational assistance whenever it was wanted. In 1893 Winkler built up his own observatory in Jena and published annual reports on his work in the Vierteljahrsschrift of the Astronomische Gesellschaft. His observational results mainly appeared in the journal Astronomische Nachrichten. In 1902 he was awarded an honorary doctor's degree by the Philosophical Faculty of Jena University. However, at that time his physical constitution began gradually to fade. He lost his left eye due to a sarcoma, and finally he died at the age of 68. In his will, he left 100 000 Mark in form of securities to Jena University (Winkler Foundation). The University Observatory got his 4.5 m dome, the transport of which from his residence to the final site was also paid for by him, several instruments, and a lot of books. In 1936 Winkler's dome was closed by the University. The observatory was transferred from the University to the Zeiss works in exchange for the observatory in the Jena Forst. Zeiss sponsored the reconstruction of the old dome

Mueller, W; Schmitz, V; Kroening, M [Fraunhofer-Institut fuer Zerstoerungsfreie Pruefverfahren, Saarbruecken (Germany)

1998-11-01

During the evaluation of ultrasonic images, e.g. SAFT-reconstructed B-scan images (SAFT=Synthetic Aperture Focusing Technique) it is often difficult to decide, what is the origin of reconstructed image points: were they caused by defects, specimens geometry or mode-conversions. To facilitate this evaluation a tool based on the comparison of data was developed. Different kinds of data comparison are possible: identification of that RF-signals, which caused the reconstructed image point. This is the comparison of a reconstructed image with the corresponding RF-data. Comparison of two reconstructed images performing a superposition using logical operators. In this case e.g. the reconstruction of an unknown reflector is compared with that of a known one. Comparison of raw-RF-data by simultaneous scanning through two data sets. Here the echoes of an unknown reflector are compared with the echoes of a known one. The necessary datasets of known reflectors may be generated experimentally on reference reflectors or modelled. The aim is the identification of the reflector type, e.g. cracklike or not, the determination of position, size and orientation as well as the identification of accompanying satellite echoes. The interpretation of the SAFT-reconstructed B-scan image is carried out by a complete description of the reflector. In addition to the aim of interpretation the tool described is well suited to educate and train ultrasonic testers. (orig./MM) [Deutsch] Bei der Auswertung von Ultraschall-Abbildungen, z.B.

This paper examines the career of Johann Sebastian Bach (1685-1750) and the role played by Wilhelm His I (who was, with Albert von Haller, a noted pioneer of physiology) in the exhumation of Bach's remains in 1894. His's examination of these remains allowed the sculptor Carl Seffner to produce the celebrated statue of Bach which stands outside the church of St Thomas in Leipzig, where the composer was employed from 1723 until his death. Modern forensic techniques have recently enabled Bach's image to be reconstructed in even more spectacular detail. © 2014 Royal Australasian College of Surgeons.

A study of the effect of ethamsylate (Dicynene) on the bleeding time, von Willebrand factor level and fibrinolysis in patients with von Willebrand's disease.

Science.gov (United States)

Hutton, R A; Hales, M; Kernoff, P B

1988-12-22

Nine patients with clinically moderate or severe Type I von Willebrand's disease were treated for 2 weeks with ethamsylate (2 g/day in four equal doses) and with a matched placebo in a randomised double-blind trial. Template bleeding time, von Willebrand factor activity (ristocetin co-factor) and antigen, euglobulin lysis time and type I tissue plasminogen activator inhibitor were determined before and at the end of each treatment period. None of these parameters showed any significant change attributable to ethamsylate. Thus, despite the fact that five patients thought subjectively that their bleeding symptoms improved during ethamsylate treatment compared to only one while on placebo, we obtained no evidence that the drug was of benefit to patients with von Willebrand's disease.

El Niño and similar perturbation effects on the benthos of the Humboldt, California, and Benguela Current upwelling ecosystems

Full Text Available To a certain degree, Eastern Boundary Current (EBC ecosystems are similar: Cold bottom water from moderate depths, rich in nutrients, is transported to the euphotic zone by a combination of trade winds, Coriolis force and Ekman transport. The resultant high primary production fuels a rich secondary production in the upper pelagic and nearshore zones, but where O2 exchange is restricted, it creates oxygen minimum zones (OMZs at shelf and upper slope (Humboldt and Benguela Current or slope depths (California Current. These hypoxic zones host a specifically adapted, small macro- and meiofauna together with giant sulphur bacteria that use nitrate to oxydise H2S. In all EBC, small polychaetes, large nematodes and other opportunistic benthic species have adapted to the hypoxic conditions and co-exist with sulphur bacteria, which seem to be particularly dominant off Peru and Chile. However, a massive reduction of macrobenthos occurs in the core of the OMZ. In the Humboldt Current area the OMZ ranges between <100 and about 600 m, with decreasing thickness in a poleward direction. The OMZ merges into better oxygenated zones towards the deep sea, where large cold-water mega- and macrofauna occupy a dominant role as in the nearshore strip. The Benguela Current OMZ has a similar upper limit but remains shallower. It also hosts giant sulphur bacteria but little is known about the benthic fauna. However, sulphur eruptions and intense hypoxia might preclude the coexistence of significant mega- und macrobenthos. Conversely, off North America the upper limit of the OMZ is considerably deeper (e.g., 500–600 m off California and Oregon, and the lower boundary may exceed 1000m. The properties described are valid for very cold and cold (La Niña and "normal" ENSO conditions with effective upwelling of nutrient-rich bottom water.

P Kasatkar

2013-01-01

Full Text Available Context: Acquired von Willebrand syndrome (AVWS is a rare bleeding disorder that mimics the inherited form of von Willebrand disease (VWD in terms of laboratory findings and clinical presentation. Aims: To study the etiology of acquired VWD. Settings and Design: The patients referred from various hospitals in and out of Mumbai were included in the study. Materials and Methods: Six patients with AVWS diagnosed at this center over the last 10 years were analyzed against 171 patients with inherited VWD. The differential diagnosis of AVWS was made based on reduced levels of von Willebrand antigen and von Willebrand ristocetin cofactor, decrease in ristocetin induced platelet aggregation, absence of correction in mixing studies with no prior history of bleeding problems and a negative family history for bleeding disorders. Results: In three patients, the disease was associated with systematic lupus erythematosus, out of which one was also associated with Kikuchi lymphadenitis and second with autoimmune hemolytic anemia. Fourth case was associated with hypothyroidism and fifth was a case of dermatitis and vitiligo. The last patient was a case of hemophilia A with Burkitts lymphoma, who developed autoantibodies to von Willebrand factor. Except two patients, all other patients responded to immune suppressive therapy with corticosteroids, while the patient with hypothyroidism responded to oral thyroxine. Conclusion: AVWS is a rare condition and may often be missed or diagnosed as inherited disease associated with heterogeneous disease conditions.

These included the first measurement of the neutral pion’s life-time. Called to Lund University in 1964, he became professor there in 1965 and director of the 1.2 GeV electron accelerator. In the late 1960s, he performed an experiment at CERN’s PS that measured the decays of the Λ. Then, in the early 1970s, he involved the Lund group in a series of experiments at the Intersecting Storage Rings (ISR), where he measured the production of various types of particles. In particular, he participated in a series of experiments that observed the production of a high abundance of particles with large transverse momenta. This required an explanation...

von Neumann's hypothesis concerning coherent states

International Nuclear Information System (INIS)

Zak, J

2003-01-01

An orthonormal basis of modified coherent states is constructed. Each member of the basis is an infinite sum of coherent states on a von Neumann lattice. A single state is assigned to each unit cell of area h (Planck constant) in the phase plane. The uncertainties of the coordinate x and the square of the momentum p 2 for these states are shown to be similar to those for the usual coherent states. Expansions in the newly established set are discussed and it is shown that any function in the kq-representation can be written as a sum of two fixed kq-functions. Approximate commuting operators for x and p 2 are defined on a lattice in phase plane according to von Neumann's prescription. (leeter to the editor)

limit values shows that a returning of the fly ash on forest areas is generally possible. Due to the high content of Zn of 1100 mg/kg in the fly ash a returning to agricultural areas is not allowed. (orig.) [Deutsch] Bei den Konversionsverfahren (Vergasung und Verbrennung) zur thermischen Nutzung von Biomasse sollen die anfallenden Rueckstaende (Aschen) moeglichst als Duengemittel auf Forst- oder Agrarflaechen zurueckgefuehrt aber keinesfalls deponiert werden. Hierzu duerfen insbesondere die Schwermetallkonzentrationen in den Aschen gewisse Grenzwerte nicht ueberschreiten. Zur Untersuchung des Schwermetallverhaltens bei der Umwandlung von Biomassen werden Messungen zum Einfluss der Konversionstemperatur (1000-1300 C), der Gasatmosphaere (reduzierend, oxidierend) und der Entstaubungstemperatur (300-750 C) in einer halbtechnischen Anlage bei einem Systemdruck von 1,2 bar durchgefuehrt. Kernstuecke der Anlage sind ein Flugstromreaktor (Reaktionslaenge 2500 mm, Innendruchmesser 70 mm) und ein Kerzenfilter mit 6 Filterelementen vom Typ DIA-Schumalith 10-20 (60/40 x 1500). Der Biomassestrom betraegt 6 kg/h. Die Ergebnisse der Schilfgrasvergasung werden als Mittelwerte ueber den Temperaturbereich von 1000 bis 1160 C bei einer konstanten Filtertemperatur von 550 C in Form von Metallkonzentrationen der Elemente Si, Al, Ca, Fe, Mg, Na, K, Pb, Zn, Cr, Cu und Ni in Schilfgrasasche, Schlacke, Flugasche und Produktgas angegeben. Die Angabe von An- und Abreicherungsfaktoren fuer die verschiedenen Elemente in Flugasche und Schlacke verdeutlichen das Verhalten der Metalle waehrend des Konversionsprozesses. Die Konzentrationen der nichtfluechtigen bzw. schwerfluechtigen Elemente Si, Al, Ca, Fe, Mg und K sind in der Schilfgrasasche, in der Schlacke und in der Flugasche nahezu gleich. Die Konzentrationen der umweltrelevanten Schwermetalle Cr, Pb und Zn sind jeweils in der Schlacke zum Teil deutlich niedriger als in der Schilfgrasasche. Diese Schwermetalle reichern sich in der Flugasche an

The Humboldt Bay Power Plant is located near Eureka, California, about 265 miles north of San Francisco. The plant consists of two fossil fueled units, two mobil gas turbine peaking units, and a nuclear unit - Unit No. 3. Unit No. 3, which utilized a boiling water reactor, was constructed between 1960 and 1963. The unit began commercial operation in August 1963 and operated until July 2, 1976 when it was shutdown for refueling, seismic modifications, and additional seismic and geologic studies. During the years Unit 3 operated it had one of the best operating records of any nuclear power plant in the United States. For its operating lifetime Unit 3 had an overall capacity factor of 63.0% and an availability factor of 85.9%. The unit included certain design features which made it unique among nuclear power plants of its era. Some of these unique features included natural circulation recirculation flow which eliminated the need for costly recirculation pumps, utilization of a pressure suppression containment system which had been developed jointly by PG and E and the General Electric Company, and the fact that the reactor vessel and the containment system were constructed in a caisson below ground level. These design features reduced the overall construction cost of the unit and improved its inherent safety

Zielwert der Analyse war die binäre Variable steinfrei versus Restfragmente, gegen die alle präoperativen Parameter mittels multivariater logistischer Regression getestet wurden. Die Erfolgsrate betrug 95,5 %; 42 Patienten (20,8 % waren steinfrei und 151 Patienten (74,7 % hatten sog. klinisch insignifikante Restfragmente (5 mm oder kleiner. Von den Männern waren 14,9 %, von den Frauen 29,6 % steinfrei (p = 0,01. Alle anderen Parameter erreichten keine statistische Signifikanz, möglicherweise aufgrund zu kleiner Subgruppen (fehlende statistische Macht. Die Desintegrationsrate des HM-3 für Nierensteine ist insgesamt ausgezeichnet, bei Frauen noch besser als bei Männern. Gerade wegen dieser hohen Erfolgsrate wären größere Patientenzahlen notwendig, um eventuelle Unterschiede zwischen den präinterventionellen Parametern definieren zu können.

Ruetzel, Stefan; Stolzenberger, Christoph; Fechner, Susanne; Dimler, Frank; Brixner, Tobias; Tannor, David J.

2010-10-01

Recently we introduced the von Neumann representation as a joint time-frequency description for femtosecond laser pulses and suggested its use as a basis for pulse shaping experiments. Here we use the von Neumann basis to represent multidimensional molecular control landscapes, providing insight into the molecular dynamics. We present three kinds of time-frequency phase space scanning procedures based on the von Neumann formalism: variation of intensity, time-frequency phase space position, and/or the relative phase of single subpulses. The shaped pulses produced are characterized via Fourier-transform spectral interferometry. Quantum control is demonstrated on the laser dye IR140 elucidating a time-frequency pump-dump mechanism.

Retracing the footsteps of Wilhelm Wundt: explorations in the disciplinary frontiers of psychology and in Völkerpsychologie.

Science.gov (United States)

Wong, Wan-chi

2009-11-01

In 1927, Wilhelm Wundt's daughter, Eleonore Wundt, compiled and published a comprehensive catalogue of her father's works and works in translation. We use this catalogue as a starting point for an examination of the breadth of Wundt's contributions, the reaction to his works from the international psychological community, and the overall trajectory of his academic career. Two areas of particular interest are Wundt's view on the nature of psychology and its relationship to other disciplines, and his discussion of the nature of Völkerpsychologie and its role in psychology. A close examination of original sources reveals that Wundt anchored psychology in the realm of mental sciences. He regarded "psychology [to be] in relation to natural sciences the supplementary, in relation to the mental sciences the fundamental, and in relation to philosophy the propaedeutic empirical science." The accomplishments and limitations of Wundtian Völkerpsychologie are viewed stereoscopically through the lenses of its explicated conceptions, goals, and methods, on one hand, and of the contemporary advancements in psychology, on the other. Current implications of Wundt's works and further developments of his ideas are related to Davidson's theory of epistemology and to present-day deliberations on the biocultural coconstruction of human development. We conclude by considering the continuing relevance of Wundt's intellectual legacy.

Barg, Ewa; Wikiera, Beata; Basiak, Aleksander; Głab, Ewa

2006-01-01

Von Recklinghausen's disease belongs to a group of neurocutaneous syndromes and is characterised by skin, nerve and bone abnormalities. We present a case of von Recklinghausen's disease and precocious puberty in 7-year-old boy. At the age of three café au lait spots on the skin and an incranial tumour situated near the optic chiasm--qualified as inoperable--were discovered. At the age of 7 first signs of precocious puberty appeared (pubic hair P3 and enlargement of the testes (15 ml) and penis). Laboratory measurements included: LH 7.5 mIU/ml, FSH 1.1 mIU/ml, testosterone 183 ng/ml, assessment of bone age: 9 years. The response to LHRH stimulation was characteristic for true precocious puberty (LH 15.9 mIU/ml and FSH 1.5 mIU/ml after 30 minutes). The MRI of the brain showed a tumour of the suprasellar region with compression of pituitary stalk. True precocious puberty was diagnosed. Treatment with Diphereline was introduced. At present the boy is 9 years old and has been treated with Diphereline for 16 months. The volume of the testicles has decreased to 7 ml and loss of pubic hair was noted. The MRI does not show any progression in tumour growth. The authors would like to underline the need of close observation of children with von Reclinghausen disease with regard to possibility of uncovering true precocious puberty which is critical for rapid diagnosis and introduction of correct treatment.

We discuss information-theoretic concepts on infinite-dimensional quantum systems. In particular, we lift the smooth entropy formalism as introduced by Renner and collaborators for finite-dimensional systems to von Neumann algebras. For the smooth conditional min- and max-entropy, we recover similar characterizing properties and information-theoretic operational interpretations as in the finite-dimensional case. We generalize the entropic uncertainty relation with quantum side information of Tomamichel and Renner and discuss applications to quantum cryptography. In particular, we prove the possibility to perform privacy amplification and classical data compression with quantum side information modeled by a von Neumann algebra

Four lysimeter trials performed on an IS-type soil yielded an almost constant range of displacement of a tracer front (NO{sub 3} front) of 4.0 to 4.5 mm / l of seepage water (referred to a surface area of 1 m-2 and a depth of 1 m). This was experimental confirmation of a tentatively formulated simplified relationship between seepage water volume, vertical tracer displacement, and field capacity. The results were also in very good agreement with those of a control study in the open field carried out under similar hydrological, pedological, and agrotechnical conditions using lysimeters and Cl tracers for determining quantities of seepage water formation. As the present lysimeter trials mirror soil hydrological processes in the open field with sufficient accuracy, they appear well suited to take the place of the so often lacking territorial data as a means of validating mathematical models describing seepage-water-bound material export. [Deutsch] Auf der Basis von 4 Lysimeterversuchen konnte fuer die Bodenart IS ein nahezu konstanter Wertebereich fuer die Verlagerung einer Tracerfront (NO{sub 3}-Front) in Hoehe von 4,0 bis 4,5 mm/l Sickerwasser (bezogen auf eine Oberflaeche von 1 m{sup 2} und eine Tiefe von 1 m) ermittelt werden. Damit konnte die vereinfachte Beziehung zwischen Sickerwassermenge, Tracerverlagerungstiefe und Feldkapazitaet experimentell bestaetigt werden. Ein Vergleich zur Bestimmung der Sickerwassermengenbildung mit Hilfe von Lysimetern und durch Einsatz von Cl-Tracern unter aehnlich hydrologischen, pedologischen und agrotechnischen Bedingungen im Freiland wies eine hohe Uebereinstimmung auf. Da die hier durchgefuehrten Lysimeteruntersuchungen bodenhydrologische Prozesse von Freilandflaechen mit ausreichender Genauigkeit widerspieglen, erscheinen sie anstelle oft fehlender Gebietskenndaten zur Validierung von mathematischen Modellen zur Beschreibung sickerwassergebundener Stoffaustraege gut geeignet.

Von Bertalanffy's dynamics under a polynomial correction: Allee effect and big bang bifurcation

Science.gov (United States)

Leonel Rocha, J.; Taha, A. K.; Fournier-Prunaret, D.

2016-02-01

In this work we consider new one-dimensional populational discrete dynamical systems in which the growth of the population is described by a family of von Bertalanffy's functions, as a dynamical approach to von Bertalanffy's growth equation. The purpose of introducing Allee effect in those models is satisfied under a correction factor of polynomial type. We study classes of von Bertalanffy's functions with different types of Allee effect: strong and weak Allee's functions. Dependent on the variation of four parameters, von Bertalanffy's functions also includes another class of important functions: functions with no Allee effect. The complex bifurcation structures of these von Bertalanffy's functions is investigated in detail. We verified that this family of functions has particular bifurcation structures: the big bang bifurcation of the so-called “box-within-a-box” type. The big bang bifurcation is associated to the asymptotic weight or carrying capacity. This work is a contribution to the study of the big bang bifurcation analysis for continuous maps and their relationship with explosion birth and extinction phenomena.

Patton, J. R.; Leroy, T. H.

2009-12-01

transects are located in each of eight archival domains in order to evaluate archival bias and potential deformation sources for the southern Cascadia subduction zone. These domains are located in the Eel River, Humboldt Bay, Humboldt Lagoons, and Crescent City regions. In any given domain, evidence of earthquakes can be regional, local, or both. Core transects are designed to capture archival bias due to 1) interseismic deformation in the upper plate or the megathrust, 2) rupture on upper plate thrust faults, 3) rupture on the megathrust, or 4) rupture on both. Modern biogeochemical transects are used to calibrate paleontologic estimates. Based on our assessment, we determine which sites need better age control, which sites need supplemental coring, and key new research areas that need to be investigated.

Von Neumann entropy in a Rashba-Dresselhaus nanodot; dynamical electronic spin-orbit entanglement

Safaiee, Rosa; Golshan, Mohammad Mehdi

2017-06-01

The main purpose of the present article is to report the characteristics of von Neumann entropy, thereby, the electronic hybrid entanglement, in the heterojunction of two semiconductors, with due attention to the Rashba and Dresselhaus spin-orbit interactions. To this end, we cast the von Neumann entropy in terms of spin polarization and compute its time evolution; with a vast span of applications. It is assumed that gate potentials are applied to the heterojunction, providing a two dimensional parabolic confining potential (forming an isotropic nanodot at the junction), as well as means of controlling the spin-orbit couplings. The spin degeneracy is also removed, even at electronic zero momentum, by the presence of an external magnetic field which, in turn, leads to the appearance of Landau states. We then proceed by computing the time evolution of the corresponding von Neumann entropy from a separable (spin-polarized) initial state. The von Neumann entropy, as we show, indicates that electronic hybrid entanglement does occur between spin and two-dimensional Landau levels. Our results also show that von Neumann entropy, as well as the degree of spin-orbit entanglement, periodically collapses and revives. The characteristics of such behavior; period, amplitude, etc., are shown to be determined from the controllable external agents. Moreover, it is demonstrated that the phenomenon of collapse-revivals' in the behavior of von Neumann entropy, equivalently, electronic hybrid entanglement, is accompanied by plateaus (of great importance in quantum computation schemes) whose durations are, again, controlled by the external elements. Along these lines, we also make a comparison between effects of the two spin-orbit couplings on the entanglement (von Neumann entropy) characteristics. The finer details of the electronic hybrid entanglement, which may be easily verified through spin polarization measurements, are also accreted and discussed. The novel results of the present

Virgin Valley opal district, Humboldt County, Nevada

The Virgin Valley opal district, Humboldt County, Nevada, is near the Oregon-Nevada border in the Sheldon Game Refuge. Nineteen claims owned by Jack and Toni Crane were examined, sampled, and tested radiometrically for uranium. Numerous discontinuous layers of opal are interbedded with a gently-dipping series of vitric tuff and ash which is at least 300 ft thick. The tuff and ash are capped by a dark, vesicular basalt in the eastern part of the area and by a thin layer of terrace qravels in the area along the west side of Virgin Valley. Silicification of the ash and tuff has produced a rock that ranges from partly opalized rock that resembles silicified shale to completely altered rock that is entirely translucent, and consists of massive, brown and pale-green opal. Carnotite, the only identified uranium mineral, occurs as fracture coatings or fine layers in the opal; in places, no uranium minerals are visible in the radioactive opal. The opal layers are irregular in extent and thickness. The exposed length of the layers ranges from 8 to 1, 200 ft or more, and the thickness of the layers ranges from 0. 1 to 3. 9 ft. The uranium content of each opal layer, and of different parts of the same layer, differs widely. On the east side of Virgin Valley four of the seven observed opal layers, nos. 3, 4, 5, and 7, are more radioactive than the average; and the uranium content ranges from 0. 002 to 0. 12 percent. Two samples, taken 5 ft apart across opal layer no. 7, contained 0. 003 and 0. -049 percent uranium. On the west side of the valley only four of the fifteen observed opal layers, nos; 9, , 10, 14, and 15, are more radioactive than the average; and the uranium content ranges from 0. 004 to 0. 047 percent. Material of the highest grade was found in a small discontinuous layer of pale-green opal (no. 4) on the east side of Virgin Valley. The grade of this layer ranged from 0. 027 to 0. 12 percent uranium.

Dependence of the wind climate of Ireland on the direction distribution of geostrophic wind; Die Abhaengigkeit des Windklimas von Irland von der Richtungsverteilung des geostrophischen Windes

The wind climate of Ireland is calculated using the Karlsruhe Atmospheric Mesoscale Model KAMM. The dependence of the simulated wind energy on the direction distribution of geostrophic wind is studied. As geostrophic winds from the south-west are most frequent, sites on the north-west coast are particularly suited for wind power stations. In addition, geostrophic wind increases from the south-east to the north-west. (orig.) [Deutsch] Das Windklima von Irland wurde mit dem Karlsruher Atmosphaerischen Mesoskaligen Modell KAMM berechnet. Hier wird die Abhaengigkeit der simultierten Windenergie von der Richtungsverteilung des geostrophischen Windes untersucht. Da geostrophische Winde aus Suedwest am haeufigsten vorkommen, eignet sich besonders die Nordwestkueste als Standort fuer Windkraftanlagen. Zusaetzlich nimmt auch der mittlere geostrophische Wind von Suedost nach Nordwest zu. (orig.)

The Furstenberg recurrence theorem (or equivalently Szemerédi’s theorem) can be formulated in the language of von Neumann algebras as follows: given an integer k ≥ 2, an abelian finite von Neumann algebra (M,τ) with an automorphism α : M→M, and a nonnegative a in M with τ(a) > 0, one has liminf
