Three-dimensional printing of models for preoperative planning and simulation of transcatheter valve replacement

In this study, we show the use of three-dimensional printing models for preoperative planning of transcatheter valve replacement in a patient with an extreme porcelain aorta. A 70-year-old man with severe aortic stenosis and a porcelain aorta was referred to our center for transcatheter aortic valve replacement. Unfortunately, the patient died after the procedure because of a potential ischemic event. Therefore, we decided to fabricate three-dimensional models to evaluate the potential effects of these constructs for previous surgical planning and simulation of the transcatheter valve replacement.

Siberian Wooden Churches: Reality and Symbolics

The preservation of Siberia's cultural heritage poses a serious problem. Many Siberian churches were destroyed or reconstructed, without their original form being carefully described. Mainicheva studied the question of Siberian wooden churches of the 17th-18th centuries, producing a complex analysis of their symbolism, phenomenology and morphology. Published and archival materials show that such unique churches as the Sophia Cathedral in Tobolesk (1621), the Trinity Church in Tomsk (1654) and the Church of Kazan Holy Mother in Ilimsk (1679) directly reflected the main features of medieval Russian culture combined with new perceptions of Man and the Universe. These Russian Orthodox churches have considerable significance for understanding the natural development of Russian architecture as a part of the Russian culture of permanently moving people. All these churches, which no longer exist in their original form, were built by unknown folk builders and represented a good example of non-professional architecture. Mainicheva developed full descriptions of the churches, including graphic reconstructions of their original plans and facades.

Schulterprothetik und Sport

In the last years life duration of shoulder prostheses could be prolonged through improvement of prosthesis quality, instrumentation and surgical techniques. After shoulder total arthroplasty, the patients show signifi cant reduction of pain and good functional mid and long term results. Indication to shoulder arthroplasty can be made by even younger and sportive active patients. Many sport activities remain possible after implantation of a shoulder prosthesis. A systematic rehabilitation is mandatory to yield optimal functional results. Intensity of sports activities should remain in relation with the preoperative status. Activities with total contact and high impaction strength should be avoided to extend the duration of life of the prosthesis.

Investigations on an egyptian coffin and mummified head from Burgdorf Museum, Switzerland - A case of a historical puzzle

In the Burgdorf Museum of Ethnology, a mummy rests in a coffin. According to the inventory book, it was purchased from the Cairo Egyptian museum in 1926. The coffin was now examined by Egyptologists and the mummy was radiocarbon dated and examined by Anthropologists. The aim of the study was to compare the results and to check whether mummy and coffin actually belong together. The skull was examined morphological-anthropologically and by CT as a “blank sample”. Coffin and skull imply that the individual was female. The coffin dates to the Ptolemaic period. Only skull bones are preserved, the ethmoid is damaged. CT images Show resinous substances, bone fragments and brain remnants inside the skull. The ethmoid bone was probably foraminated during the mummification process and thus ended up inside the skull. The individual was mummified between the New Kingdom and the Ptolemaic period. Due to its style, it is most probable that the coffin comes from the Gamhud necropolis. The Burgdorf museum of ethnology inventory book chronicles were largely falsified by the examinations. There is a time gap between coffin and the mummy, there are two possible interpretations: the body was mummified with older linen, or the mummy and the coffin do not belong together. The authors strongly advise further investigations.

Pulmonary fat embolism - a prospective study within the forensic autopsy collective of th eRepublic of Iceland

In the last century, studies established the origin of pulmonary fat embolism (PFE) and identified mechanical trauma as main source for PFE. This prospective study focused on determining a possible influence of cardiopulmonary resuscitation (CPR), in the context of an aging population, on the occurrence of PFE. Lung tissue samples from 256 bodies were examined using the twin-edged knife technique without preliminary fixation but after staining with Sudan III. PFE grading was determined according to Falzi and performed at a 10× magnification. For statistical analysis, bodies were grouped by age, gender, and putrefaction and categorized following whether they had experienced trauma, CPR, the combination of both, or no mechanical impact. There was a significant correlation of trauma, CPR, and the combination of both to PFE but no noticeable influence of gender or putrefaction. An age over 70 years promotes a PFE due to resuscitation.

Plant diversity effects on the water balance of an experimental grassland

In the literature, contrasting effects of plant species richness on the soil water balance are reported. Our objective was to assess the effects of plant species and functional richness and functional identity on soil water contents and water fluxes in the experimental grassland of the Jena Experiment. The Jena Experiment comprises 86 plots on which plant species richness (0, 1, 2, 4, 8, 16, and 60) and functional group composition (zero to four functional groups: legumes, grasses, tall herbs, and small herbs) were manipulated in a factorial design. We recorded meteorological data and soil water contents of the 0·0–0·3 and 0·3–0·7 m soil layers and calculated actual evapotranspiration (ETa), downward flux (DF), and capillary rise with a soil water balance model for the period 2003–2007. Missing water contents were estimated with a Bayesian hierarchical model. Species richness decreased water contents in subsoil during wet soil conditions. Presence of tall herbs increased soil water contents in topsoil during dry conditions and decreased soil water contents in subsoil during wet conditions. Presence of grasses generally decreased water contents in topsoil, particularly during dry phases; increased ETa and decreased DF from topsoil; and decreased ETa from subsoil. Presence of legumes, in contrast, decreased ETa and increased DF from topsoil and increased ETa from subsoil. Species richness probably resulted in complementary water use. Specific functional groups likely affected the water balance via specific root traits (e.g. shallow dense roots of grasses and deep taproots of tall herbs) or specific shading intensity caused by functional group effects on vegetation cover.

Vom Kommentieren

In Germanistic philological editing, theoretical discussion on the commentary assumes traditionally a secondary role compared to the manifold contributions on other subjects of textual philology. Already in 1924, Georg Witkowski admonished to enhance scholarly debates on the commentary, and the claim has since been repeated several times. This paper reflects current discussions in the context of contemporary annotation practice, wishing to trigger new considerations of how the intellectual genesis of text and the contexts of literary works can be adequately illustrated in the commentaries.

Collingwood on religious atonement

R. G. Collingwood’s philosophical analysis of religious atonement as a dialectical process of mortal repentance and divine forgiveness is explained and criticized. Collingwood’s Christian concept of atonement, in which Christ TeX the Atonement (and also TeX the Incarnation), is subject in turn to another kind of dialectic, in which some of Collingwood’s leading ideas are first surveyed, and then tested against objections in a philosophical evaluation of their virtues and defects, strengths and weaknesses. Collingwood’s efforts to synthesize objective and subjective aspects of atonement, and his proposal to solve the soteriological problem as to why God becomes flesh, as a dogma of some Christian belief systems, is finally exposed in adversarial exposition as inadequately supported by one of his main arguments, designated here as Collingwood’s Dilemma. The dilemma is that sin is either forgiven or unforgiven by God. If God forgives sin, then God’s justice is lax, whereas if God does not forgive sin, then, also contrary to divine nature, God lacks perfect loving compassion. The dilemma is supposed to drive philosophy toward a concept of atonement in which the sacrifice of Christ is required in order to absolve God of the lax judgment objection. God forgives sin only when the price of sin is paid, in this case, by the suffering and crucifixion of God’s avatar. The dilemma can be resolved in another way than Collingwood considers, undermining his motivation for synthesizing objective and subjective facets of the concept of atonement for the sake of avoiding inconsistency. Collingwood is philosophically important because he asks all the right questions about religious atonement, and points toward reasonable answers, even if he does not always deliver original philosophically satisfactory solutions.

Catching Reality or Bowing Disciplines: How to Move the Study of Citizenship

In his contribution, Joppke justifies his selection of foundational scholars by linking each to what he sees as the three key facets of citizenship: status, rights and identity. Maarten Vink explicitly links his research agenda to the first, status, and outlines why it is so important. In identifying three facets of citizenship, Joppke acknowledges that some academics would include political participation, but he ultimately decides against it. But here we can, and should, broaden citizenship studies by bringing in insights from the behavioral politics tradition in domestic politics - when and why people engage in political acts - and from the social movements literature in sociology. I believe that the American debate on immigration reform, admittedly stalled, would not have advanced as far as it has without the social movement activism of DREAMers - unauthorized young people pushing for a path to citizenship - and the belief that Barack Obama won re-election in part because of the Latino vote. Importantly, one type of political activism demands formal citizenship, the other does not. As many contributors note, the “national models” approach has had a significant impact on citizenship studies. Whether one views such models through a cultural, institutional or historical lens, this tends to be a top-down, macro-level framework. What about immigrants’ agency? In Canada, although the ruling Conservative government is shifting citizenship discourse to a more traditional language - as Winter points out - it has not reduced immigration, ended dual citizenship, or eliminated multiculturalism, all goals of the Reform Party that the current prime minister once helped build. “Lock-in” effects (or policy feedback loops) based on high immigrant naturalization and the coming of age of a second-generation with citizenship also d emands study, in North America and elsewhere. Much of the research thus far suggests that political decisions over citizenship status and rights do not seem linked to immigrants’ political activism. State-centered decision-making may have characterized policy in the early post-World War II period in Europe (and East Asia?), but does it continue to hold today? Majority publics and immigrant-origin residents are increasingly politicized around citizenship and immigration. Does immigrant agency extend citizenship status, rights and identity to those born outside the polity? Is electoral power key, or is protest necessary? How is citizenship practiced, and contested, irrespective of formal status? These are important and understudied empirical questions, ones that demand theoretical creativity - across sub-fields and disciplines - in conceptualizing and understanding citizenship in contemporary times.

Political Sociology of Islam Integration: the Role of Liberal Law

In Europe and North America, migration and integration has become a busy subfield of political sociology. Of particular interest in this respect is the integration of Muslims and Islam, which has dominated the debate in Europe. Broadly conceived «political opportunity structures» have received much attention in this context. But the role of liberal law in the integration of Islam has been largely ignored, not by lawyers of course, but by political sociologists who have thus delivered far too negative and truncated pictures of Muslims and Islam in Europe. This is the deficit we sought to redress in Legal Integration of Islam; A Transatlantic Comparison (2013) (co-authored with John Torpey). Some of this study’s main ideas and findings are presented in the following.
