Mesh fistulation into the rectum after laparoscopic ventral mesh rectopexy
No full textAbstractINTRODUCTIONLaparoscopic ventral mesh rectopexy (LVMR) is an effective method of management of functional disorders of the rectum including symptomatic rectal intussusception, and obstructed defaecation. Despite the technical demands of the procedure and common use of foreign body (mesh), the incidence of mesh related severe complications of the rectum is very low.PRESENTATION OF CASEA 63 year old woman presented with recurrent pelvic sepsis following a mesh rectopexy. Investigations revealed fistulation of the mesh into the rectum. She was treated with an anterior resection.DISCUSSIONThe intraoperative findings and management of the complication are described. Risk factors for mesh attrition and fistulation are also discussed.CONCLUSIONChronic sepsis may lead to ‘late’ fistulation after mesh rectopexy
Ultrafilters en Ultramachten
No full textIn deze scriptie gaan we twee wiskundige objecten onderzoeken, het ultrafilter en de ultramacht. Zodra je in de wiskunde een nieuw object hebt bedacht zijn de eerste twee vragen die je stelt altijd 1) bestaat het? en 2) Als het bestaat, is het dan uniek, of zijn er meerdere? Nou is dat voor een ultrafilter relatief makkelijk te beantwoorden. In hoofdstuk 1 zijn we bezig om allerlei nuttige eigenschappen van het ultrafilter te onderzoeken. Voor een ultramacht echter is het wel duidelijk dat die bestaat, maar het kost nog veel werk om uit te vinden of er meerdere zijn. Bij dat antwoord speelt de Continuümhypothese een belangrijke rol. In de wiskunde is het duidelijk dat de natuurlijke getallen N en de reële getallen R verschillende soorten oneindig zijn. De Continuumhypothese stelt dat er geen enkele andere soort oneindigheid tussen N en R ligt. Het blijkt dat het antwoord op de vraag “Zijn er twee verschillende ultramachten?” precies samenhangt met of de Continuümhypothese waar is. Om tot dit antwoord te komen gaan we een eigenschap van ultramachten onderzoeken genaamd “gaten”. We kunnen dan bij verwerping van de Continuümhypothese twee ultramachten aanwijzen die verschillende gaten hebben en dus verschillend zijn.Applied Mathematic
The synthesis and characterization of processable precursor polymers to articulated polyfphenylene benzobisoxazoles containing the 2.5-disubstituted-1.4-bicyclor2.2 21 octyl ring system., 1995
No full textProcessable precursor polymers to articulated poly(phenylene benzobisoxazoles), PBOs, have been prepared and studied. The precursor polymers were synthesized by the polycondensation of l,4-bicyclo[2.2.2]octyl-2,5-diethanoate dicarboxylic acid or 1,4- bicyclo[2.2.2]octyl-2,5-diol dicarboxylic acid with 3,3'-dihydroxy-4,4'-diaminobiphenyl or 2,2'-bis(3-amino-4-hydroxyphenyl)hexafluoropropane in poly(phosphoric acid), PPA. The precursor polymers were characterized by solubility, viscosity, spectroscopy (infrared, proton and carbon-13 NMR) and thermal analysis such as, differential scanning calorimetry, thermogravimetric analysis and optical polarizing microscopy. Thermogravimetic analysis (TGA) indicates that the precursor polymers are generally stable up to ca. 220� and 350� in air and under nitrogen atmosphere, respectively. Conversion of the precursor polymers to the more stable poly(phenylene benzobisoxazoles) is achieved by pyrolysis in air or under nitrogen atmosphere
The workshop as the work: white anti-racism organising in 1960s, 70s, and 80s US social movements
No full textThis thesis explores the rise of anti-racism workshops developed by white activists in various United States social movements from the late 1960s through the mid-1980s. The shifting ideology of the black freedom movement in the late 1960s, from integration to Black Power, transformed white activists‘ place within racial justice struggles. While recent scholarship has begun to turn its attention towards whites‘ ongoing racial justice activities, one of the most radical and widespread of these efforts is consistently overlooked: anti-racism workshops. Increasingly prevalent from the late 1960s through to the diversity-trainings explosion of the 1990s, this thesis demonstrates that these workshops had their roots in the black freedom, women‘s liberation and gay liberation movements. White activists from these movements led these workshops in order to examine white racial domination and privilege within both leftist social movements and larger US society.
Analysing case studies from the black freedom, women‘s liberation and gay liberation/rights movements, this thesis explores the foundational assumptions of anti-racism workshops. It seeks to explain how and why these efforts sought to frame race and racism as issues of knowledge and consciousness and why such efforts constituted radical praxis. It is argued that early anti-racism workshops were pedagogical projects that sought to confront the racial ignorance that structured the lives of whites in the US, including progressives and their liberation movements. This thesis draws attention to the efficacy and power of these workshops in terms of their epistemological effects, in the transformations they brought about in whites‘ understanding, or awareness, of racial realities
Let’s talk about race:considerations for course design in public administration
No full textThe chapter is a reflexive account of the author's experience of introducing race to public administration discussions. The first section of the chapter summarises the influence of critical race theory (CRT) in the pedagogic approach taken to teach an undergraduate course. Given the Black Lives Matter moment and impact of COVID, which has affected particular demographics more deeply, the author re-imagines the possibilities of teaching race to future public administrators with a specific focus on systemic racism. The second section introduces what critical race practice (CRP) is and puts forward counter storytelling and community service learning as pedagogies of engagement aligned to CRP. Having strategies for creating brave spaces for dialogue and managing students' resistance is vital for a learning environment to aid critical discussions on sensitive topics. Finally, this chapter considers whether the race of an instructor matters and concludes that expertise in critical race pedagogies is most important

サンヴィセンテ島民と日本人漁師の文化接触 : カーボヴェルデの「サイコー」な人たちは誰だったのか
No full textThe islands of Cabo Verde are known as one of the oldest Creole areas in the world. It was originally discovered by the Portuguese in the mid-fifteenth century. Since their settlement, the Portuguese brought people from West Africa as slaves which made birth the concept of creole in Cabo Verde. The phenomenon of creole is a linguistic and cultural product surged through a dynamism of mixture of Whites and Blacks while colonization and black slave trade have begun. Thus, Cabo Verde became a heterogeneous society.
In the eighteenth century, before the abolishment of slavery, the port of Mindelo in the island of São Vicente has developed for its supplement of coal by the British. The port of Mindelo turned to an important meeting point of various people from a different background which eventually made Mindelo to a metropolitan city. Finally, in the 1960s, the Japanese fishermen were engaged in fishery based in Mindelo until the 1970s. During their stay, koladera, a Cabo Verdean musical genre, was in a fashion and a song called “Sayko Dayo” (= ‘awesome’, ‘superb’ in Japanese) was composed by a famous musician, Ti Goy, through cultural contacts between Japanese fishermen and the people of Mindelo.
The present report shows how Japanese fishermen were evolved in the terms of the creation of the song “Sayko Dayo” and examine who were the people “Sayko” by analyzing interviews that the author has collected during fieldwork. This study can show us how people of Cabo Verde creolize their cultures
