Heterogenität der kaninen Immunantworten gegen Borrelia burgdorferi in einem Line-Immunoassay mit rekombinantem VlsE und C6-Peptid
Authors: Müller Elisabeth , Breu Doris 
Published: September 2017

ZusammenfassungGegenstand: In einem Line-Immunoassay mit sieben Antigenen sowie rekombinantem VlsE (variable major protein like sequence, expressed) und synthetischem C6-Peptid wurde die Präsenz Borreliaburgdorferi-spezifischer Antikörper (IgG) in kaninen Seren erfasst. Ziel der Studie war, die Antikörperantworten gegen das C6-Peptid und das VlsE-Protein zu vergleichen und zu evaluieren, ob diese divergieren, da Antikörper gegen die jeweiligen Antigene als spezifisch für eine stattgefundene Infektion mit Borrelien gelten. Material und Methoden: Es wurden 1355 Blutproben von Hunden analysiert, bei denen Verdacht auf eine Infektion mit Borrelien bestand. Die Testung erfolgte mittels eines Line-Immunoassays (IgG) mit neun Antigenen. Ergebnisse: Insgesamt 64,4% der Proben wurden als negativ bewertet, 16,4% als infiziert und 17,4% zeigten ein für eine Impfung spezifisches Bandenmuster. Bei 1,2% der Hunde lag sowohl eine Impfung als auch eine Infektion vor. Die am häufigsten positiv getesteten Banden waren p100 (24,3%), p31/OspA (18,5%), C6 (16,3%) und VlsE (13,9%). Bei 236 Hunden wurden Antikörper gegen das VlsE-Protein und/oder das C6-Peptid nachgewiesen. Während 73,3% dieser Hunde übereinstimmende Ergebnisse zwischen VlsE und C6 aufwiesen, unterschieden sich bei 26,7% die Resultate. Schlussfolgerung und klinische Relevanz: Die Testung mittels Line-Immunoassay erlaubt eine qualitative Analyse der unterschiedlichen IgG-Immunantworten gegen verschiedene Antigene. Die Resultate der Immunantworten gegen die als infektionsspezifisch geltenden Antigene VlsE und C6 divergierten bei mehr als 26% der positiv getesteten Hunde unserer Population, sodass zum Ausschluss oder der Bestätigung einer Infektion mit Borrelia burgdorferi möglichst unterschiedliche infektionsspezifische Banden berücksichtigt werden sollten.

ZusammenfassungGegenstand und Ziel: Untersuchung über das Vorkommen von Ehrlichia (E.) canis bei in Deutschland lebenden Hunden sowie Evaluierung der Möglichkeiten und Grenzen von indirekten und direkten Diagnostikmethoden. Material und Methode: Im ersten Teil der Studie wurden retrospektiv Ergebnisse von Proben aus der Routinediagnostik ausgewertet, bei denen auf Einsenderwunsch (als Einzeluntersuchung oder als Teil eines Laborprofils zur Abklärung von Reisekrankheiten) E.-canis-Antikörper mithilfe eines indirekten Immunfluoreszenztests (IFAT) bestimmt worden waren. Im zweiten Teil wurde bei Proben, bei denen im Rahmen eines Reisekrankheitenprofils ein IFAT zum Nachweis von E.-canis-Antikörpern erfolgte, zusätzlich eine Polymerase-Kettenreaktion (PCR) auf E.canis-DNA durchgeführt. Bei den E.-canis-positiven Hunden (Tiere, die in IFAT und/oder PCR positiv waren) und bei einem Teil der negativ getesteten Hunde wurde eine Anamnese erhoben. Ergebnisse: Im Jahr 2015 ließen sich bei 11,8% von 12220 untersuchten Proben E.-canis-Antikörper nachweisen. Von 1172 Hunden, bei denen ein Reisekrankheitenprofil bestimmt wurde, wiesen 5,6% Antikörper gegen E. canis auf (Untersuchungszeitraum Februar bis März 2016). Dabei waren unter den E.-canis-positiven Hunden (n = 67) 91% nur im IFAT positiv, 7,5% im IFAT und in der PCR und 1,5% hatten nur einen positiven PCR-Befund. Der anamnestischen Auswertung zufolge wurden vor allem klinisch gesunde Importhunde mit dem Reisekrankheitenprofil innerhalb ihres ersten Jahres in Deutschland gescreent. Schlussfolgerung und klinische Relevanz: Wenngleich endemische E.-canis-Infektionen in Deutschland eine untergeordnete Rolle spielen, hat der Erreger hierzulande Bedeutung, insbesondere durch den Import von Hunden. Daher ist eine Anamnese bezüglich Auslandsaufenthalt oder Import besonders wichtig, um eine Ehrlichiose frühzeitig zu diagnostizieren und adäquat behandeln zu können. Bei importierten E.-canis-seropositiven Hunden, die in dieser Studie häufig keine klinischen Symptome zeigten, war der Erregernachweis aus dem Blut mittels PCR meist negativ. Die Diagnostikmethode sollte daher abhängig von der Krankheitsphase und der zugrundeliegenden Fragestellung (Symptomatik oder Vorsorgescreening) gewählt werden.

Technologies of Imagination: Locating the Cloud in Sweden’s North
Authors: Vonderau Asta 
Published: September 2017

Abstract | When in 2011 a world-leading IT company expressed the intention to locate its infrastructure in the Swedish city of Luleå, this announcement immediately triggered future scenarios and visions of a new industrial era, economic prosperity, and changing urban life. Such anticipation was supported and shaped by municipal planning and business-management activities that soon materialized in the form of building sites, regional development strategies, and new markets. Since the actual name and operations of the IT company were kept entirely secret, the planning and implementation of “Project Gold”—as the data centre project was called locally—was as much driven by collective imaginaries as by hard facts or past experiences. This article is based on an ethnographic study that followed the implementation of Facebook’s first European data centre in Luleå. The paper analyzes different modes of data centre infrastructural (in)visibility and shows how imaginaries became influential both for implementing the cloud in Luleå and for shaping the anticipated time and space of “post-extractive modernity.” More specifically, the paper focuses on socio-technical preconditions as well as concrete practices and styles—technologies of imagination—enabling those imaginaries.
Uncertain Architectures—Performing Shelter and Exposure
Authors: Veel Kristin 
Published: September 2017

Abstract | Originally housed in generic industrial buildings, data centres have become sites of architectural feats and playgrounds for starchitects in recent years. These buildings testify to a changed role of how we think of these repositories for data and their position in our society. Through a reading of the Bahnhof data centre Pionen in Stockholm from 2008 and the design schematic for a Data Tower in Iceland, this article examines how the data centre as an architectural and infrastructural edifice facilitates data storage and access, focusing on how security is articulated in the architectural vocabulary through negotiations of visibility. By intermingling images of these sites with textual vignette-like reflections, this article uses the architecture of the data centre to address how the design of dynamic data archives embodies cultural imaginaries of uncertainty through the tropes of shelter and exposure.Résumé | Initialement hébergés dans des bâtiments industriels génériques, les centres de données sont devenus récemment des merveilles d’architecture et des terrains de jeux pour les « starchitects ». Ces bâtiments témoignent d’un changement de rôle dans la façon dont nous pensons à ces entrepôts de données et à leur position dans notre société. Grâce à une lecture du centre de données Bahnhof Pionen à Stockholm à partir de 2008 et au schéma de conception d’une tour de données en Islande, cet article examine comment le centre de données, en tant qu’édifice architectural et infrastructure, facilite le stockage et l’accès aux données, en mettant l’accent sur la façon dont la sécurité est articulée dans le vocabulaire architectural à travers les négociations de visibilité. En entremêlant les images de ces sites avec des réflexions textuelles semblables à des vignettes, cet article utilise l’architecture du centre de données pour aborder comment l’élaboration de centre de données dynamiques incarne des imaginaires culturels d’incertitude à travers les tropes d’abris et d’exposition.

Abstract | This short experimental essay reflects upon our video Points of Presence. In producing the video we used unmanned aerial drones to visually and vertically examine undersea fibre-optic cables of the North Atlantic. We reflect upon how the drone’s flying technologies allow pilots to creatively engage with the atmospheric element. We argue that the drone’s optical and object-avoidance technologies share similarities with the mammalian senses. In concluding, we examine how drones and information infrastructures reflect each other as complex and imperfect systems designed to extend the human body and senses across geographies.Résumé | Ce court essai expérimental se penche sur notre vidéo Points of Presence. En produisant la vidéo, nous avons utilisé des véhicules aériens sans pilote pour examiner visuellement et verticalement les câbles de fibres optiques sous-marins de l’Atlantique Nord. Nous réfléchissons à la façon dont les technologies de navigation du drone permettent aux pilotes d’interagir de manière créative avec l’aspect atmosphérique. Nous soutenons que les technologies optiques et d’évitement des objets du drone partagent des similitudes avec les sens des mammifères. En conclusion, nous examinons comment les drones et les infrastructures d’information se reflètent comme des systèmes complexes et imparfaits conçus pour prolonger le corps humain et les sens à l’échelle de la planète.

Vibrations of soil and foundation due to railway, blast and impact loading
Authors: Auersch Lutz 
Published: September 2017

The vibrations of soil and foundations are demonstrated for different types of loading. Train-induced ground vibrations are studied in a measurement cam­paign where a test train has run with regularly varied speeds. The measured train-induced soil vibration at 2 to 100 m distance from the track is compared with the wave propagation due to hammer excitation and with the theoretical wave field. The strong influence of the soil and the train speed on the amplitudes and frequencies of the vibration has been analysed for passages of the locomotive and the carriages. - The generation of ground vibration by strong explosions has been studied on a large testing area with sandy soil. The propagating waves were measured in a regular grid of measuring points in 10 to 1000 m. Therefore, the dominance of certain waves at certain distances and the changes of compressio­nal waves and Rayleigh waves could clearly be observed. The results are compa­red with impulse hammer measurements in the range of 5 to 50 m. - A drop test facility has been built on the testing area of the Federal Institute of Materials Research and Testing (BAM). Heavy masses (containers) of up to 200 t can be dropped from 10 m height on a big reinforced concrete foundation. The founda­tion was instrumented by accelerometers, strain gauges and pressure cells to give information about the loading condition and by geophones to measure the vibra­tion of the surrounding soil and building. Both excitation processes, the release of the mass and the impact, produce high vibration amplitudes. On a smaller drop foundation, the influence of the drop height and the target stiffness has been studied more systematically.
The role of the university in terms of realisation of freedom of teaching and freedom of scientific research – polish case
Authors: Syryt Aleksandra 
Published: September 2017

Abstract: The terms "university", "teaching" and "research" are closely related. The reason for the establishment of a community of learners and students were, on the one hand, the formation of man, and on the other the search for the truth about man, life, society and the world. In the face of technological development and access to information, including the development of legislation that allows the individual, without going through formal institutions, data acquisition, the question arises whether the university is needed, and if so, what is its role in realizing the right to education and freedom of scientific research. Implementation of freedom of scientific research and freedom of teaching in times of universal information access and modern technology can do without the university. However, this is university that can benefit from innovative research methods and teaching remains the most important forum for the exchange of ideas and the search for truth and knowledge transfer, vocational skills and social attitudes.Keywords: Right to education. Freedom of scientific research. Constitution. Cultural rights. Freedom of teaching. Resumo: Os termos "universidade", "ensino" e "pesquisa" estão intimamente relacionados. A razão para o estabelecimento de uma comunidade de alunos e estudantes foram, por um lado, a formação do homem, e por outro a busca da verdade sobre o homem, a vida, a sociedade e o mundo. Em face de desenvolvimento tecnológico e do acesso à informação, incluindo o desenvolvimento de uma legislação que permite que o indivíduo, sem passar por instituições formais, tenha acesso a dados e a informações, gera a questão de saber se a universidade é necessária, e em caso afirmativo, qual é o seu papel na realização dos direitos à educação e à liberdade de pesquisa científica. A implementação da liberdade de investigação científica e liberdade de ensino em tempos de acesso à informação universal e tecnologia avançada pode se realizar sem a universidade. No entanto, a universidade pode se beneficiar de métodos inovadores de pesquisa e de ensino e continuar a ser o mais importante fórum para a troca de ideias ea busca da verdade e da transferência de conhecimentos, competências profissionais e as atitudes sociais.Palavras-chave: Direito à Educação.

Published: September 2017

IntroductionThe aim of this case report is to present a distinct subtype of gingival inflammatory hyperplasia, providing information to avoid diagnostic mistakes and overtreatment. Also, an unexpected progression of the lesion is shown. Furthermore, a review of the literature to discuss the pathogenesis, diagnosis, treatment, and the need for new therapeutic approaches is presented.Case SeriesThe authors report four cases of localized juvenile spongiotic gingival hyperplasia involving the anterior maxillary gingiva with distinct clinical features. The patients were followed for a period of 1 to 9 years, and the evolution of the lesions was documented. Surgical excision or therapy by topical steroids was used to treat the lesions.ConclusionsThe long‐term follow‐up provides important information for clinicians not to eliminate older patients for lesion diagnosis. Although surgical excision should not be recommended for all cases, considering the risk of esthetic problems, the treatment modality using topical steroids was not permanently effective in the authors’ cases. Investigations about new esthetic treatment modalities for lesions are needed.

Published: September 2017

IntroductionMinimally invasive surgical techniques in periodontics, including methods for ridge augmentation, have been shown to achieve surgical goals while minimizing swelling, decreasing postoperative discomfort, and enhancing soft tissue architecture. The present case illustrates a minimally invasive guided bone regeneration technique for augmentation of a deficient alveolar ridge in the esthetic zone.Case PresentationA 30‐year‐old patient received localized ridge augmentation utilizing tunnel access for guided bone regeneration with a dense polytetrafluoroethylene membrane and a freeze‐dried bone allograft. The patient experienced minimal postoperative swelling and discomfort, and the procedure resulted in favorable ridge dimensions for implant placement.ConclusionsThe tunnel access for guided bone regeneration presented in this case may offer advantages similar to other minimally invasive ridge augmentation techniques. Further controlled clinical study is warranted.

Gonzaga Duque e a fotografia
Authors: Gonçalves Cássia Denise 
Published: September 2017

O artigo trata da presença da fotografia nos escritos do crítico literário e de artes plásticas, contista e autor de romance Luiz Gonzaga Duque Estrada (1863-1911) a partir da qual é esboçada uma possível “imagem” que este possuía acerca do papel da fotografia nas artes plásticas. Nas obras consultadas não foi localizada uma análise específica de Gonzaga Duque sobre a fotografia, mas entradas que, direta ou indiretamente, apontam para o assunto em questão. Esta ausência chama atenção, pois a maior parte dos seus escritos corresponde a um período – entre o final do século XIX e a primeira década do século XX – no qual a imagem fotográfica já havia sido incorporada ao universo das artes visuais, seja como parte do processo de composição das obras, seja como meio de documentação e difusão da arte: a fotografia da obra de arte.
