Images of eternity in 3D

Lucarelli, Rita 20 April 2016 (has links) (PDF)
By using the technique of photogrammetry for the 3D visualization of ancient Egyptian coffins decorated with magical texts and iconography, this project aims at building up a new digital platform for an in-depth study of the ancient Egyptian funerary culture and its media. It has started in August 2015 through the support of a Mellon Fellowship for the Digital Humanities at UC Berkeley and up until now it has focused on ancient Egyptian coffins kept at the Phoebe A. Hearst Museum of Anthropology of UC Berkeley. The main outcome will be a digital platform that allows to display a coffin in 3D and where users will be able to pan, rotate, and zoom in on the coffin, clicking on areas of text to highlight them and view an annotated translation together with other metadata (transcription of the hieroglyphic text, bibliography, textual variants, museological data, provenance, etc.)

Abordagem artroscópica do recesso palmar da articulação interfalângica distal pela bainha dos tendões flexores digitais em eqüinos / Arthroscopic approach of the palmar recess of the distal interphalangeal joint, through the digital flexor tendon sheath in horses

Ferreira, Marcio Augusto 18 March 2005 (has links)
Por meio deste estudo objetivou-se avaliar a viabilidade de um novo acesso artroscópico para o recesso palmar da articulação interfalângica distal em eqüinos pela bainha sinovial comum aos tendões flexores digitais, com as finalidades de proporcionar segurança e eficiência durante a artrocentese, permitir visualização efetiva das estruturas anatômicas, além de criar condições para manipulação de instrumentos artroscópicos. Foram utilizadas 20 peças anatômicas, correspondentes aos membros torácicos de 10 eqüinos. Os conjuntos de um a cinco formaram o Grupo I, cujo o acesso cirúrgico foi medial, e os conjuntos seis a 10 formaram o Grupo II, onde o acesso cirúrgico foi lateral. Posteriormente, avaliou-se o procedimento em animais de experimentação com a aplicação da técnica artroscópica proposta em seis articulações interfalângicas distais dos membros torácicos de três eqüinos (GIII), sem enfermidade previamente diagnosticada através de exames físicos e radiográficos. Os procedimentos no Grupo III foram efetuados sob anestesia geral, em decúbito lateral, e todos animais foram observados durante seis semanas. Neste período, além da avaliação dos parâmetros físicos, foram efetuados controles radiográficos contrastados, visando a avaliar a recuperação e o tempo necessário para oclusão da membrana divisória entre a bainha digital e o interior da articulação interfalângica distal. A técnica proposta alcançou os objetivos propostos, oferecendo nova alternativa para o acesso ao recesso palmar da articulação interfalângica distal nos eqüinos / This study was carried out in order to evaluate the viability of a new arthroscopic approach of the palmar recess of the the interphalangeal joint in horses through the synovial sheath that involves the digital flexor tendon. The purposes of the study were to provide safety and efficiency during arthrocentesis, to allow effective visualization of the anatomical structures and provide means for the manipulation of arthroscopic instruments. Initially, 20 anatomic parts corresponding to the forelimbs of 10 horses were used. Sets numbers 1 through 5 formed Group I in wich a medial surgical approach was performed. Sets numbers 6 through 10 formed Group II, in which there was a lateral surgical approach. Later, the procedure in experimental animals was analyzed. This analysis was done using the proposed arthroscopic technique in 6 distal interphalangeal joints of the forelimbs of three horses (GIII). There was no previously disease diagnosed through physical and radiographic exams. The procedures in Group III were done under put general anesthesia in the lateral recumbence position and all the animals were under observation during six weeks. In the post-operative period a physical and contrasted radiographic exams were done to evaluate the recovery as well as the necessary healing time of the membrane between the digital sheath and distal interphalangeal joint. The technique responded positively to its objectives offering a new alternative to the approach of the palmar recess in the distal interphalangical joint in horses

Le Corps en Égypte ancienne. Enquête lexicale et anthropologique / The Body in Ancient Egypt. A lexicological and anthropological Study

Martin, Anaïs 30 November 2013 (has links)
À partir des premiers corpus funéraires de l’Égypte ancienne (Textes des Pyramides et Textes des Sarcophages), cette étude propose une nouvelle approche de la conception de la personne dans la pensée égyptienne, par le truchement de la notion de corps. De fait, parmi l’ensemble des éléments connus pour composer la personne (le ka, le ba, le ib, le nom, l’ombre…), le corps est le seul à pouvoir être désigné par différents termes, à savoir Haw, XA.t ou D.t. Ceci implique donc que le corps connaît plusieurs états, chacun entretenant des relations distinctes avec l’un ou l’autre des composants de la personne. Celle-ci n’étant pas considérée comme une somme d’éléments constants dans le temps et dans l’espace, l’étude de la notion de corps et de ses différents aspects permet ainsi d’appréhender la personne dans sa globalité, qu’il s’agisse de celle de l’homme ou des dieux. Dans cette perspective, l’intérêt des textes funéraires considérés est de présenter la personne du défunt, évoquant ainsi à la fois ses caractéristiques terrestres et divines. Cette recherche est envisagée selon deux axes, avec dans un premier temps une analyse lexicographique des termes Haw, XA.t et D.t. Une seconde partie est ensuite consacrée à l’analyse anthropologique, visant à détailler le système de représentation de la personne en déterminant les différences entre la personne humaine ou divine, mais également à travers les transformations subies par le défunt. / Founded on the early funerary literature of Ancient Egypt (Pyramids Texts and Coffin Texts), this research intend to offer a new approach on the concept of person in the egyptian thinking through the notion of body. Indeed, among all the components of the person (ka, ba, ib, name, shadow…), the body is the only one which can be designated by different words, namely Haw, XA.t or D.t. therefore, it suggests that the body can have different states of being, each one having distinctive relationships with one or the other element. As the person is not considered as a sum of different permanent components in time and space, the study of the notion of body and of its various aspects allow us to grasp the concept of person as a whole, in human context as well as divine. Thus, from this viewpoint, the interest of the funerary literature is to present the person of the deceased, with his characteristics of both kinds. This study is led in two ways, with first a lexicological analysis of the words Haw, XA.t and D.t. Then a second part presents the anthropological analysis, aiming at detail the system of representation of the person in the Egyptian way of thinking by defining the differences between human and divine person, and through the transformations endured by the deceased.

The Effect of CTE Mismatch on Solder Ball in Optoelectronic Packaging

Liu, An-Chan 25 July 2003 (has links)
Two subjects are included in this thesis; one is to construct the Coffin-Manson equation of the unleaded SnAgCu solder according to the experimental results provided by the Metal Research Laboratory (MRL) of Industrial Technologies Research Institute (ITRI). The results of CSP thermal cycle fatigue and SOJ pull tests and the corresponding stress and strain distributions solved from FEM analyses have been used to derive the Coffin-Manson equation for the SnAgCu solder. The other subject is to investigate the effect of CTE mismatch on the fatigue life of solder balls in the opto-electronic packaging. The solidified shapes of the different solder balls after undergoing the re-flow process are predicted by employing the Surface Evolver package program. The FEA meshes of the solidified solder balls in opto-electronic packaging are built according to the output results of the Surface Evolver program. The maximum equivalent plastic shear strain range of the solder after under one thermal cycle process is calculated by employing the MARC finite element package. The fatigue lives of solder balls under different arrangements are estimated according to the proposed Coffin-Manson equation. The effect of solder ball parameters, i.e. solder volume, solder offset distance, solder DNP and solder material on the reliability of different solder balls has also been explored in this thesis.

Coffin hardware analysis and chronology of the Head Cemetery, Robertson County, Texas

Basse, Karissa Anne 25 November 2013 (has links)
Atkins performed an archaeological relocation of a nineteenth century cemetery on behalf of Luminant Mining Company, within the Kosse Mine in Robertson County, Texas between the years of 2011 and 2012. The Head Cemetery offers unique opportunities to examine views of death and burial in rural, central Texas during the period of the early statehood until around 1900. The Head family and other members of the settlement were part of a pioneer community exhibiting clear expressions of family and community affiliations through spatiality and the material culture of burials. An analysis of coffin hardware and burial practices provides suggestions for dating and identifying unknown interments and exploring changing sentiments towards death by Anglo American settlers within the broader sociohistorical context of the nineteenth century. / text

Gristhorpe Man: an Early Bronze Age log-coffin burial scientifically defined

Melton, N., Montgomery, Janet A., Knüsel, Christopher J., Batt, Catherine M., Needham, S., Parker Pearson, M., Sheridan, A. January 2010 (has links)
A log-coffin excavated in the early nineteenth century proved to be well enough preserved in the early twenty-first century for the full armoury of modern scientific investigation to give its occupants and contents new identity, new origins and a new date. In many ways the interpretation is much the same as before: a local big man buried looking out to sea. Modern analytical techniques can create a person more real, more human and more securely anchored in history. This research team shows how.

Gristhorpe Man: a Raman spectroscopic study of 'mistletoe berries' in a Bronze Age log coffin burial

Edwards, Howell G.M., Montgomery, Janet, Melton, Nigel D., Hargreaves, Michael D., Wilson, Andrew S., Carter, E.A. 10 February 2010 (has links)
No / In 1834 in a tumulus at Gristhorpe, North Yorkshire, UK, an intact coffin fashioned from the hollowed-out trunk of an oak tree was found to contain a well-preserved skeleton stained black from the oak tannins, wrapped in an animal skin and buried with a range of grave artefacts, including a bronze dagger, flints and a bark vessel. The remains were deposited in the Rotunda Museum at Scarborough, where closure due to refurbishment in 2005–2008 provided an opportunity for the scientific investigation of the skeletal remains and artefacts using a wide range of techniques. Dendrochronological and radiocarbon dating has established the age of the skeleton as 2140–1940 BC at 95% confidence, in the Early Bronze Age. As part of this project, Raman spectra of several mysterious small spherical objects discovered in the coffin underneath the skeleton and initially believed to be ‘mistletoe berries’ associated with ancient burial customs have been recorded non-destructively. The interpretation of the Raman spectral data, microscopic analysis and comparison with modern specimens has led to the conclusion that the small spheres are phosphatic urinary stones, which reflect the archaeological dietary evidence and stable isotope analysis of bone collagen of Gristhorpe Man.
