This layer is part of a selection of digitally scanned and georeferenced historic maps from The Harvard Map Collection as part of the Imaging the Urban Environment project. Maps selected for this project represent major urban areas and cities of the world, at various time periods. These maps typically portray both natural and manmade features at a large scale. The selection represents a range of regions, originators, ground condition dates, scales, and purposes.

Valutazione sperimentale in-vitro di nuove superfici protesiche per la sostituzione totale di caviglia derivanti da un innovativo approccio morfologico

La sostituzione totale di caviglia o artroplastica totale di caviglia (Total Ankle Replacement - TAR) è un'operazione eseguita per sostituire le superfici di contatto delle ossa di tibia e astragalo mediante componenti protesiche e sta diventando una comune procedura chirurgica per il trattamento dell’ultimo stadio di osteoartrite di caviglia. La morfologia articolare della caviglia e la relativa cinematica sono molto complesse. Gli attuali dispositivi per TAR soffrono ancora di alti tassi di insoddisfazione e fallimento, probabilmente a causa dei relativi disegni protesici non pienamente rispettosi della normale morfologia di caviglia e del normale trasferimento dei carichi articolari. Recentemente, è stato proposto un nuovo disegno basato su un originale postulato che approssima la superficie articolare talare in modo maggiormente fisiologico, come un tronco di cono a sella con apice diretto lateralmente. L'obiettivo di questa tesi di laurea è di valutare sperimentalmente, mediante il supporto del navigatore chirurgico, il comportamento cinematico derivante dall’impianto del dispositivo TAR basato sul nuovo postulato e di confrontarlo con la cinematica derivante dalla caviglia intatta e derivante da modelli protesici basati sui disegni più comunemente utilizzati. Dieci arti inferiori da cadavere con caviglie intatte e normali, sono state scansionati via CT. Le immagini di caviglia sono state poi segmentate per la produzione dei modelli virtuali articolari. Questi sono stati prodotti sia basandosi sul nuovo postulato sia su quelli standard, e successivamente stampati in materiale plastico via 3D-printing. I risultati ottenuti a seguito di elaborazioni confermano che il nuovo dispositivo sembra riprodurre meglio rispetto agli altri, il fisiologico comportamento funzionale della caviglia, presentando valori prossimi a quelli della caviglia naturale.

Geochemistry and microfossil content of surface sediments from the Equatorial Atlantic in samples 207 to 310 from the Meteor expedition in 1925

Als Alfred Merz mich aufforderte, die sedimentpetrographische Bearbeitung der "Meteor"-Expedition zu übernehmen, schwebte mir von vornherein als Ziel vor, die Sedimente nicht nur in größerer Zahl als bisher und im Zusammenhang mit den übrigen Wissenschaften vom Meer nach den bisherigen Untersuchungsmethoden zu beschreiben. Es war mir klar, daß neue Ergebnisse nur zu erwarten waren, wenn die Untersuchung der Sedimente und damit ihre Beschreibung auf Grund vertiefter und neuer Methoden unternommen wurde. Ich erhoffte von einer solchen verfeinerten Beschreibung auch ein klareres Bild der Abhängigkeit der Sedimente von ihrer Umwelt. Wir werden diese Abhängigkeit nur verstehen, wenn wir die allgemeinen Gesetzmäßigkeiten herausarbeiten können. Diese werden dann auch eine Anwendung auf andere Sedimente ermöglichen. Für solche Untersuchungen sind Tiefseesedimente günstig, weil wir bei ihnen relativ einfache Bildungsumstände haben, einfacher jedenfalls, als es in der Flachsee im allgemeinen der Fall ist, ungünstig aber, weil diese Umwelteinflüsse weniger bekannt und schwerer zu erforschen sind und die Auswahl der Untersuchungspunkte nicht nach sedimentpetrographischen Gesichtspunkten erfolgen konnte. Die ersten Jahre nach der Rückkehr von der Expedition wurden deshalb auf methodische Untersuchungen verwandt. Insbesondere kam es mir darauf an herauszubekommen, wie die feinsten Bestandteile der Sedimente zusammengesetzt sind. Diese "tonigen" Bestandteile bilden nicht nur den wesentlichen Anteil der Roten Tone und der Blauschlicke, wir finden sie auch, durch Kalk verdünnt, in den Globigerinenschlämmen wieder. Sie sind von der Wissenschaft bisher recht stiefmütterlich behandelt worden. Die Ausarbeitung der Methoden, die gerade auf diesem Gebiet Neuland betreten mußte, ließ sich nicht rasch erzwingen. Es kam hinzu, daß ich mir in Rostock erst meine Arbeitsmöglichkeiten schaffen mußte. Ich habe hier der Notgemeinschaft der Deutschen Wissenschaft und der Mecklenburgischen Regierung für ihre Unterstützung mit Apparaten und Personal wärmstens zu danken. Ferner mußte als Vorbedingung für die Deutung der Sedimente zunächst festgestellt werden, zu welchen geologischen Zeiten sie gebildet worden sind und wie groß ihre Bildungsgeschwindigkeit überhaupt ist. Diese Untersuchungen hat W. Schott mit Hilfe der Foraminiferenfaunen als Notgemeinschaftsstipendiat durchgeführt. Diese Vorarbeiten, insbesondere der Ausbau der Methoden, hatten den Nachteil, daß die Veröffentlichung der Ergebnisse nicht so rasch erfolgen konnte, wie ich es selbst gewünscht hätte. Bald nachdem die Darstellung der Methoden und die Foraminiferenuntersuchungen als erste Lieferung erschienen waren, stellte es sich als notwendig heraus, eine beträchtliche Kürzung des restlichen Teiles vorzunehmen. Das hat zur Folge, daß die erste Lieferung breiter dargestellt ist als die Ergebnisse. Als die Nachricht von der Kürzung und dem notwendigen raschen Abschluß des Werkes mir bekannt wurde (Januar 1935), mußte eine Reihe von Untersuchungen eingestellt werden, insbesondere mikroskopische Untersuchungen, die besonders viel Zeit und in der Darstellung viel Raum beanspruchen. Deshalb ist systematisch nur das Guinea-Becken durch V. Leinz und das Kapverden-Becken durch O. E. Radczewski untersucht worden.
