Full textAbstract:
Hydropower is an important source of energy in Sweden and accounts for about 46 % of the total energy production. Sweden has about 1 200 hydropower plants and with the intention of raising the pressure head of the water and to store water, dams are built by the power plants. The storage reservoirs make it possible to adjust the energy production by demand and season. Dams in connection to the reservoirs are subjected to additional loading during periods of high floods or when an icecap in the winter is formed on the reservoirs. In order to maintain the dam safety, the power companies in Sweden are working with guidelines for dam safety from RIDAS. An important part of the work of dam safety is FDU that is carried out with purposes of improving the work of dam safety. A FDU made for the Skålan dam in the River of Ljungan showed that the levels of the safety factors for sliding and overturning of the dam was not fulfilled when subjected to loads from an icecap. The object of this thesis was to follow up the FDU and by carrying out extensive stability calculations on all parts of the Skålan dam, investigate what safety factors the different parts will get and also investigate some proposal measures in order to increase the dam stability.
The stability calculations for the dam have been performed according to directions in RIDAS at four loading cases. Loading case I and II means a water level to the retained water level and an ice load of 200 and 100 kN/m respectively. Loading case III and IV means a situation without ice load but with a water level to the retained water level respectively a water level to a meter above the retained water level. The stability of the dam was studied with regards to sliding and overturning. The results from the stability calculations showed for both loading case I and II that the majority of the parts of the Skålan dam did not fulfill the levels of the safety factors. The calculations also showed that some parts of the dam did not fulfill the stability criteria of sliding at loading case III, which implies that these parts of the dam actually have not enough weight.
The measure proposals studied were the ice preventive measures IR-elements and circulation of the deep warm water and the stability increasing measure with pre strained rock anchorages. The net present value (NVP) for the different measures were calculated with a life length of the dam estimated to 60 years. The results from the calculations of the NVP showed that the most economically feasible measure is circulation of the water but when considering the results from the stability calculations, the most suitable measure is the rock anchorages. Therefore, a combination of rock anchorages on parts which not fulfills the stability criteria in combination with circulation of the water is suggested to be the best measure.
Vattenkraften är en viktig energikälla i Sverige som utgör ca 46 % av den totala energiproduktionen. I Sverige finns det ca 1 200 kraftverk och i syfte att öka fallhöjden och lagra vatten bygger man dammar i anslutning till kraftverken. Dammarna skapar stora magasin med vatten och gör det möjligt att anpassa elproduktionen efter säsong och behov.
Dammar och kraftverk vid vattenmagasinen utsätts för extra belastning under perioder med höga flöden samt vid islaster och för att upprätthålla dammsäkerheten har man tagit fram RIDAS - kraftföretagens riktlinjer för dammsäkerhet. Inom ramen för dammsäkerhetsarbete utförs fördjupade dammsäkerhetsutvärderingar, FDU, för att arbeta förebyggande och hitta möjligheter till förbättring av dammsäkerhetsarbetet. I en FDU gjord för Skålandammen i Ljungan påvisades att de av RIDAS uppsatta säkerhetsfaktorerna för glidning och stjälpning inte uppfylldes vid islast. Syftet med detta arbete var att följa upp FDU:n och med utförliga stabilitetsberäkningar på Skålandammens alla delar (monoliter) undersöka hur dessa klarar säkerhetsfaktorerna vid olika lastfall, hur stort problemet med islast är samt ta fram åtgärdsförslag för att öka dammens stabilitet.
Beräkningarna har utförts enligt RIDAS anvisningar för stabilitetsberäkningar vid fyra olika lastfall där de två första innebär en vattennivå till magasinets dämningsgräns samt en islast på 200 respektive 100 kN/m och de två andra behandlar en situation utan islast men med en vattennivå till dämningsgränsen respektive en vattennivå till 1 meter över dämningsgränsen. Stabiliteten kontrollerades med avseende på stjälpning och glidning.
Resultatet av stabilitetsberäkningarna visade att för majoriteten av Skålandammens monoliter uppfylls inte stabilitetskraven vid en islast på vare sig 200 eller 100 kN/m. Det visades även att ett fåtal monoliter inte uppfyller säkerhetskraven för glidning vid lastfallet utan islast med en vattennivå till dämningsgränsen, vilket indikerar på att dessa monoliter är för lätta.
De isfrihållande åtgärdsförslagen som jämfördes var IR-element och cirkulering av vattnet med hjälp av luftbubblor och den stabilitetshöjande åtgärden med förspända bergförankringar. Nuvärdet för dessa åtgärder beräknades sedan med antagandet att dammen har en livslängd på 60 år. Resultatet från nuvärdesberäkningen visade att det billigaste alternativet är cirkulering av vattnet men utifrån stabilitetsberäkningarna är det mest fördelaktigt att använda den stabilitetshöjande åtgärden med bergförankringar. Med anledning av detta föreslås ett alternativ med bergförankringar på de monoliter som inte uppfyllde säkerhetskraven vid lastfall utan is i kombination med cirkulering av vattnet som den mest lämpliga åtgärden.

Full textAbstract:
There are many old dams in Sweden and, since few dams are constructed today, the main task in risk assessment on the existing dams is often to reduce the risk of failure. RIDAS (Swedish Guidelines on Dam Safety) is used when designing new dams and assess the existing ones. The guidelines include stability requirements for different failure modes, e.g. overturning and sliding, which imply that the load effect from e.g. uplift and ice load need to be less than the resisting loads or moments. The ice load in RIDAS is given as a deterministic value depending on where in Sweden the dam is located. For many years, ice and ice load have been researched, but there is still a lack of knowledge regarding the magnitude of the ice load and how it affects the probability of failure for dams. More knowledge about the actual ice load would result in a lower calculated probability of failure for the dam which could be used to design slender dams or avoid unnecessary reinforcement of existing dams. Dam safety evaluation is often performed with deterministic methods based on safety factors. In recent years, the use of probabilistic methods in dam design has increased. The method has an advantage compared to deterministic methods in safety evaluations of existing dams, since probabilistic methods provide an answer to which parameters that have the greatest impact on the stability of the dam and take into account the variations in each parameter. I this master thesis, a statistical distribution for the variation of the ice load’s annual maximum value was calculated. This was used in the analysis of the probability of failure for solid gravity concrete dams and buttress concrete dams. The probability of failure was calculated for dams of different sizes for overturning and sliding failure modes, and also for three different load cases; without ice load, with a truncated ice load distribution and with an ice load distribution that has not been truncated. The probabilistic stability analysis was conducted in Comrel with ice load as one of the stochastic variables. It was found which sizes of the dams that have the largest impact from the ice load; also what effect extreme values on the ice load has on the failure probability of the dam. The results indicated that the probability of failure for dams lower than 15 m is more affected by the ice load, for both failure modes analyzed. The probability of failure is reduced for all dam types when eliminating extreme values of the ice load, particularly for dams lower than 15 m. In several cases, truncation of the ice load distribution is the difference between an accepted and a non-accepted level of the probability of failure. It is also shown that reduced coefficient of variance for the ice load results in a decreased probability of failure. The conclusion is that solid gravity dams and buttress dams lower than 15 m, with a high consequence class, should be risk assessed with the ice load as a stochastic variable. The statistical distribution of the ice load is still uncertain and the distribution used in this report should not be used globally, rather in areas with a climate similar to northern Sweden. The reason for this is that the measurements that were used to derive the global distribution were mainly performed in areas with conditions similar to those in northern Sweden. A recommendation for further research is to focus on determining statistical distributions for the ice load for southern, central and northern Sweden. An alternative is to use different ice load distributions for the different areas. Another alternative could be to use the same statistical distribution for southern, central and northern Sweden but with different values for where the ice load distribution is truncated, depending on the maximal ice thickness in each area. The recommendation is also to develop a reliable method for measuring the ice load. In addition, attempts should be made to determine whether extreme values on the ice load really exist or if they are effects of measurement errors. Key words: concrete dams, ice load, probabilistic stability analysis, probability of failure

Full textAbstract:
It is essential to understand the mechanics of ice load and how it affects concrete dams located in a cold climate, such as Sweden, where the temperature becomes sufficiently cold to freeze the surface of the reservoir. The purpose of this thesis is to study ice load distribution along concrete dams, and its response during the application of an ice load. Two types of concrete dams were analysed, an arch dam and a buttress dam. For these dams, the influence from different parameters on the ice load distribution along the dams is studied. In addition to this, a study on how the ice load affects dam stability had also been performed. Stability analyses based on the finite element method were performed using both linear and nonlinear formulation of the interaction behaviour between the base of the dam and the underlying rock. A parametric study of ice sheet expansion on different dam types and geometries were performed. The expansion of the ice sheet was assumed to either be caused by a constant temperature 15 ˚C uniformly distributed over the ice thickness, or by a temperature gradient from 15 ˚C at the top surface of the ice sheet and 0 ˚C at the bottom. The parametric study also includes an investigation about influence of the shape of the reservoir beaches, where it either had a perpendicular shape towards the surface of the dam, or it had an angle of 30˚ with the dam surface. In the linear stability analysis, the structure continued to deform with increasing of the resultant pressure until it reached nonlinearity. The dam deflection had a linear relation with the applied ice load force until it reached the point when structure behaviour was nonlinear. The structure failed due to sliding, overturning or combination of both sliding and overturning. A material failure can also occur if the nonlinear material behaviour is considered, however this was not considered in this study. The parametric study showed that the ice load distribution was less near the beaches, and the distribution of the load on the concrete dam was higher near the top surface of the ice sheet. It was also shown in the study that the distribution of the ice load along the dam was as a cosine function where it had the maximum value at the buttress and the minimum at monolith connections. The result also showed that the load distribution over the thickness of the ice sheet was the same along the dam, regardless of the shape of the beaches or the length of the ice sheet.Det är viktigt att förstå hur islasten beter sig och hur den påverkar betongdammar som är belägna i kallt klimat, som t.ex. Sverige, där temperaturen blir tillräckligt låg för att frysa ytvattnet i en flod. Syftet med detta examensarbete är att studera isbelastningsfördelningen längs en betongdamm och dess respons under en belastningen. Två olika typer av betongdammar har analyserats, vilka är valvdamm samt lamelldamm. För dessa, studerades det hur olika parametrar påverkar lastfördelningen från istrycket längsmed dessa dammar. Slutligen har det studerats hur islasten påverkar dammsäkerheten och risken för dammbrott. Inverkan från interaktionen mellan dammen och det underliggande berget som linjär eller olinjärt har studerats i stabilitetsanalyser baserade på finita elementmetoden. En parameterstudie har också genomförts för olika dammtyper och geometrier där islasten orsakades av en expansion av isytan. Denna expansion antogs vara orsakad av antingen av en jämn fördelad temperatur över istjockleken på 15 ˚C, eller en temperaturgradient över istjockleken med +15 ˚C på den övre ytan och 0 °C vid isens bottenyta. Den parametriska studien beaktar även inverkan från utformningen av stränderna, där den har definierats som antingen vinkelrät mot dammen eller med en lutande vinkel på 30 grader. I fallet med linjära stabilitetsanalyser kommer konstruktionen att fortsätta att deformeras som ett resultat av ökande resulterande tryckkraft. Dammens deformation har ett linjärt förhållande med den applicerade islasten till dess att den når en punkt då strukturens beteende övergå till olinjärt. Strukturens brottmod kan uppstå på grund av glidning, stjälpning eller i en kombination av både glidning och stjälpning. materialbrott kan uppstå om icke-lineariteterna beaktas. Dammen gick till brott på grund av glidning, vältning eller i kombinationen av dessa då. Materialbrott kan uppstå om icke-linjära materialmodeller inkluderas, men detta beaktades dock ej i denna studie. Den parametriska studien visar att isbelastningen är mindre nära stränderna och att belastningen på betongdammen är högre vid isens ovanyta. Studien visar att islastfördelningen längsmed dammen liknar en cosinusfunktion som når sitt maximum vid stödskivan och sitt minimum vid monolitanslutningen. Resultatet visar även att islastfördelningen genom islastens tjocklek har samma form längsmed dammen oavsett utformningen av stränder eller istäckets längd.

Many dams existing today were constructed around fifty years ago. Condition monitoring is essential for maintaining high safety and determining the current level of safety and stability for these dams. There is a need for new monitoring techniques and finite element coupled monitoring could be one of these techniques. A concrete arch dam located in Sweden is modelled and calibrated with respect to concrete temperature measurements. The temperature distribution is then defined as a prescribed strain in a structural mechanical model in which a parametric study is performed. The results from the parametric study are compared to measurements of the crest deformation and a combination of parameters is found giving the lowest difference between measurements and model results for the mid-section. The results show that the finite element model can be used to predict the behavior of the dam with acceptable deviation. The parametric study indicates that the reference temperature of the concrete has little effect on the amplitude of the deformation and that the governing factor is the coefficient of thermal expansion.Många av de dammar som finns idag byggdes för omkring femtio år sedan. Tillståndsövervakning är avgörande för att kunna bestämma nivån av säkerhet och stabilitet för dessa dammar. Det finns ett behov av ny övervakningsteknik och finita element-kopplad övervakning kan vara en av dessa tekniker. En betongvalvdamm modelleras och kalibreras med avseende på uppmätt betongtemperatur. Den beräknade temperaturfördelningen definieras sedan som en föreskriven töjning en strukturmekanisk modell i vilken en parametrisk studie utförs. Resultaten från parameterstudien jämförs med mätningar av kröndeformation och en kombination av parametrar identifieras som ger lägsta skillnad mellan mätningar och modellresultat för mittsektionen. Resultaten visar att modellen kan användas för att förutsäga dammens beteende med acceptabel avvikelse. Parameterstudien indikerar att referenstemperaturen för betongen har liten inverkan på amplituden för deformationen och att den styrande faktorn är längdutvidgningskoefficienten.

En damm används i huvudsak för att magasinera vatten i energiutvinningssyfte. Dammen rör sig fram och tillbaka i ett säsongsmönster mestadels beroende på skillnader i utomhustemperatur och vattentemperaturen i magasinet. Det nordiska klimatet innebär risk för isläggning i magasinet, för vilken lasten är relativt outforskad. Denna rapport syftar till ett med multipla linjära regressionsmodeller samt dynamiska regressionsmodeller avgöra vilka variabler som förklarar en specifik svensk dammkonstruktions rörelse. Dammens rörelse mäts genom att mäta dammens förflyttning kontra berggrunden med data från dammens inverterade pendlar. Av särskilt intresse är att avgöra islastens påverkan på rörelsen. Resultaten visar att multipla linjära regressions-modeller inte fullständigt lyckas modellera dammens rörelse, då de har problem med autokorrelerade residualer. Detta hanteras med hjälp av autoregressiva regressionsmodeller där de initiala förklarande variablerna inkluderas, kallat dynamisk regression. Denna rapports resultat visar att de autoregressiva parametrarna fungerar mycket väl för att förklara pendlarna, men att även tid, temperatur, det hydrostatiska trycket samt istjocklek är användbara förklarande variabler. Istjockleken visar signifikant påverkan på 5 % signifikansnivå på två av de undersökta pendlarna, vilket är ett noterbart resultat. Författarna menar att rapportens resultat indikerar att det finns anledning att fortsätta forska kring islastens påverkan på dammkonstruktioner.A dam is a structure mainly used for storing water and generating electricity. The structure of a dam moves in a season-based pattern, mainly because of the difference in temperature between the air on outside of the dam and the water on the inside. Due to the Nordic climate, occurrences of icing on the water in the basin is fairly frequent. The effects of ice on the structural load of the dam are relatively unexplored and are the subject to this bachelor’s thesis. The goal of this project is to evaluate which predictors are significant to the movement of the dam with multiple linear regression models and dynamic regressions. The movement is measured by inverted pendulums that register the dam’s movement compared to the foundation. It is of particular interest to determine if the ice load influences the movement of the dam. The multiple regression models used to explain the dam’s movement were all discarded due to autocorrelation in the residuals. This falsifies the models, since autocorrelation means that they don’t meet the needed assumptions. To counteract the autocorrelation, dynamic models with autoregressive terms were fitted. These models showed no problem with autocorrelation. The result from the dynamic models were successful and managed to significantly explain the movement of the dam. The autoregressive terms proved to be efficient explanatory variables. The dynamic regression models also show that the time, temperature, hydrostatic pressure and ice thickness variables are also useful explanatory variables. The ice thickness shows a significant effect at the 5 % significance level on two of the investigated pendulums. The report's results indicate that there is reason to continue research on the ice load impact on dam constructions.

The submitted thesis seeks to answer the question "Is the relationship between Islam and terrorism uniquely determined?". It is divided into three parts. The first chapter aims to define the term terrorism, with the associated basic facts, as well as the progressive historical development. The second part is concerned with the theme of the youngest monotheistic religion - Islam. Besides the phasing its history, it includes the fundamental realities connected to it. The final chapter unifies the theory contained in the previous two sections with practice and illustrates it on the various examples of terrorist acts. The main objective is to answer the hypothesis stated in the introduction of work.

Full textAbstract:
Diabetes is a major health problem worldwide, and there is substantial interest in developing xenogeneic islet transplantation as a potential treatment. The potential to relieve the demand on an inadequate supply of human pancreata is dependent upon the efficiency of techniques for isolating and culturing islets from the source pancreata. Porcine islets are favored for xenotransplantation, but mature pigs (>2 years) present logistic and economic challenges, and young pigs (3-6 months) have not yet proven to be an adequate source. In this study, islets were isolated from 20 juvenile porcine pancreata (similar to 3 months; 25 kg Yorkshire pigs) immediately following procurement or after 24 h of hypothermic machine perfusion (HMP) preservation. The resulting islet preparations were characterized using a battery of tests during culture in silicone rubber membrane flasks. Islet biology assessment included oxygen consumption, insulin secretion, histopathology, and in vivo function. Islet yields were highest from HMP-preserved pancreata (2,242 +/- 449 IEQ/g). All preparations comprised a high proportion (>90%) of small islets (<100 mu m), and purity was on average 63 +/- 6%. Morphologically, islets appeared as clusters on day 0, loosely disaggregated structures at day 1, and transitioned to aggregated structures comprising both exocrine and endocrine cells by day 6. Histopathology confirmed both insulin and glucagon staining in cultures and grafts excised after transplantation in mice. Nuclear staining (Ki-67) confirmed mitotic activity consistent with the observed plasticity of these structures. Metabolic integrity was demonstrated by oxygen consumption rates=175 +/- 16 nmol/min/mg DNA, and physiological function was intact by glucose stimulation after 6-8 days in culture. In vivo function was confirmed with blood glucose control achieved in nearly 50% (8/17) of transplants. Preparation and culture of juvenile porcine islets as a source for islet transplantation require specialized conditions. These immature islets undergo plasticity in culture and form fully functional multicellular structures. Further development of this method for culturing immature porcine islets is expected to generate small pancreatic tissue-derived organoids termed "pancreatites," as a therapeutic product from juvenile pigs for xenotransplantation and diabetes research.

Full textAbstract:
Under många år har islam som religion varit ett omdiskuterat ämne i Sverige. Det finns många faktorer som påverkar hur vi uppfattar religionen i sin helhet. Beroende på vilket samhälle eller tid vi lever i så kommer uppfattningen att variera och diskurserna kommer att förändras genom detta. Tidigare forskning har visat att islam ofta framställs utifrån stereotypiska föreställningar där utövarna ses som annorlunda och en tro att det en rätt form av islam. Syftet med föreliggande studie är att se vilken framställning av islam i uppslagsverk som är dominerande genom tiden och se hur språket förändras eller förblr detsamma beroende på under vilken tid som uppslagsverket var författat. Detta gör att en kritisk diskursanalys utgör metoden för hur jag tolkar framställningen av islam i fem uppslagsverk. Den teoretiska anasatsen består av en postkolonial teori utifrån Saids beskrivning av orientalism tillsammans med ett socialkonstruktionistiskt angreppssätt och Otterbecks undersökning av diskursers förändring över tid. Resultatet visade att den orientaliska framställningen var genomgående framförallt i de äldre uppslagsverken där religionen framställs som sträng, fatalistisk, stereotypisk och oföränderlig och som ett typiskt österländskt fenomen utan koppling till väs. De senare verken har kvar en viss stereotypisk framställning men med en nedtonad orientalistisk diskurs. Jämställdhets och mångkultursdiskurser var två delar som var utmärkande för de senare verken men som hade en nedtonad roll i de tidiga verken. I övrigt var det tydligt att de senare verken fokuserade mer på kulturen och lärorna i islam och de tidiga verken var centrerade till den historiska och teologiska utvecklingen.

Full textAbstract:
Islet purification prior to allo transplantation currently forms the clinical gold standard, despite the fact that purification protocols result in significant islet losses and remove potential islet precursors and tissue that may provide islets with bio-trophic support Conversely, non-purified islet preparations retain endocrine mass and within the sphere of islet auto transplantation have been associated with excellent long-term graft function. This study comprises of an analysis of peri-operative factors and the long-term graft function of patients’ auto transplanted with either purified (n=14) or nonpurified islets (n=23). Complementary in-vitro studies were carried out to assess the effect of non-islet tissue on islet viability, integrity and function (n=8), whilst a histology-based study (n=23) assessed whether transplantation of non-islet cells, particularly islet precursors, had a long-term effect on graft function in the clinical setting. Clinically, non-purified islets did not significantly increase peri-transplant venous pressures and perioperative factors including ITU stay, blood loss and liver function were comparable in both groups. Analysis of the 5 year post-transplant period demonstrated that although insulin release in response to glucose was initially superior following transplant of purified islets, non-purified islets were associated with stable long-term function. In-vitro studies reiterated these findings, revealing that islet viability and function were comparable in both groups, however, retention of intracellular insulin was found to be superior within non-purified preparations with some evidence that ductal tissue provided islets with bio-trophic support. Histology-based analysis of patient pancreata suggested a positive role for islet precursors demonstrating significantly superior blood glucose, HbA1c and C-peptide values associated with the transplantation of ductal cells and non-islet PDX-1 and glucagon positive cells. The results of this study indicate that transplantation of non-purified islets can be performed safely and with comparable long-term graft function as purified islets. Additionally, these studies potentially suggest that ductal tissue may help to preserve islet integrity, whilst certain precursors cells found within the acinar parenchyma and ductal epithelium may improve long-term islet graft function.

Full textAbstract:
Islet transplantation (ITx) is an emerging and promising therapy for patients with uncontrolled type 1 diabetes. The islet isolation and purification processes require exposure to extended cold ischemia, warm-enzymatic digestion, mechanical agitation, and use of damaging chemicals for density gradient separation (DG), all of which reduce viable islet yield. In this paper, we describe initial proof-of-concept studies exploring quadrupole magnetic separation (QMS) of islets as an alternative to DG to reduce exposure to these harsh conditions. Three porcine pancreata were split into two parts, the splenic lobe (SPL) and the combined connecting/duodenal lobes (CDL), for paired digestions and purifications. Islets in the SPL were preferentially labeled using magnetic microparticles (MMPs) that lodge within the islet microvasculature when infused into the pancreas and were continuously separated from the exocrine tissue by QMS during the collection phase of the digestion process. Unlabeled islets from the CDL were purified by conventional DG. Islets purified by QMS exhibited significantly improved viability (measured by oxygen consumption rate per DNA,

Full textAbstract:
The ulama in Madura are an inseparable part of the local social structure. Their strategic position has given them an excellent opportunity to exercise a leadership role in the local context. The ulama's niche in the social order of the village and the forces that participate in the process of change can be seen through a study of village religion in a historical context. More specifically, this study examines village religion in a contemporary setting, and focuses on the internal structure of the villages and their relations to the outside world. The ulama play an important role in a number of domains, and thus occupy a central position in society. Indeed, their religious leadership has nurtured the emergence of complex networks of followers and colleagues which have, over time, sustained the stability of the ulama's leadership role in the face of social and political vicissitudes.

This thesis is based upon fieldwork carried out in the island of Apiao, in the archipelago of Chiloé, southern Chile. It is an ethnographic exploration of the way the small community of Apiao conceive of communication and interaction with both fellow human beings and supernatural creatures. The thesis describes details of every day life, with an emphasis on visiting as the main mode of social interaction. Through reciprocal hospitality the islanders enact balanced reciprocal exchange. Food and drink is offered and received; this is always returned in equal measure with a return visit. Visits between friends or neighbours are articulated according to a formal ritualistic etiquette based on asking. Balance is temporarily interrupted and small debts incurred when favors are asked. These must be reciprocated promptly. Momentary interruption of equilibrium perpetuates relations among people who describe themselves as being 'all the same'. Marriage equates to forming an independent, productive unit with a focus on inhabitants of households rather than on family in terms of decent or blood ties. Kinship terms are limited to the word mama and this refers to the grandmother, the focal role in raising children. Active memory as expression of love and care is what makes people related to each other. Kin ties must be kept active by constant love and care. Forgetful kin are in turn forgotten and slowly erased from memory. The thesis shows that religious beliefs are centered on exchange relationships with powerful entities that belong to the supernatural world. The dead and the miraculous San Antonio are powerful and ambivalent: they protect and help the living but can be revengeful and harmful if neglected by the living. Novenas are offered to the dead and the San Antonio in exchange for protection and miracles. Novenas represent a public and powerful ritual display of hospitality, enacting values of memory, solidarity and exchange.

Full textAbstract:
Le dialogue culturel méditerranéen connaît aujourd'hui une période difficile. Or, à la fois connexe et indépendante, la dimension religieuse offre un autre canal possible de dialogue dans les relations méditerranéennes. Les transformations du regard chrétien porté sur l'islam amorcées dès l'entre-deux-guerres, puis les pratiques du dialogue entre chrétiens et musulmans, en métropole et outre-Méditerranée, favorisent progressivement l'affirmation du dialogue islamo-chrétien sur le devant de la scène méditerranéenne. Dans les années 1960, le concile Vatican II marque un temps fort dans ce processus. Rattrapé par ses propres ambiguïtés et soumis aux forces de la géopolitique méditerranéenne, le dialogue islamo-chrétien entre cependant, à la fin des années 1970, dans une période plus chaotique rythmée aussi bien par des actes symboliques en faveur de la paix que par des crispations identitaires. En faisant appel à diverses sources de documentation, en particulier le fonds réuni par le Service des Relations avec l'Islam (SRI), ce travail propose un panorama historique des acteurs, des enjeux et des limites du dialogue islamo-chrétien en Méditerranée au XXe siècle. Des retours sur l'histoire et les acteurs marseillais illustrent ces évolutionsIntercultural dialogue in the Mediterranean is undergoing hard times. However the religious dimension, connected and independent at the same time, offers another possible channel of dialogue in the Mediterranean relations. The transformations of the Christian perception of Islam started during the interwar period, then the practices of the dialogue between Christians and Muslims, in mainland France and beyond the Mediterranean Sea, gradually promote the Islamo-Christian dialogue on the Mediterranean forefront. In the 1960s, the Second Vatican Council stands out in this process. Trapped inside its own ambiguities and conditioned by Mediterranean geopolitical settings, the Islamo-Christian dialogue however enters a much more chaotic period punctuated both by symbolic acts for peace and identical tensions at the end of 1970s. Inspiring by multiple documentation sources, in particular by the collection of the Service des Relations avec l'Islam (SRI), the present work offers an historic overview of the actors, the stakes and the limits of the Islamo-Christian dialogue in the Mediterranean Sea throughout the 20th century. Historic reviews and the actors from Marseille illustrate such development

Studien behandlar hur islam presenteras i svenska läromedel för religionsundervisningen på högstadienivå. Syftet och frågeställningarna med studien är att undersöka hur beskrivningen av islam har utvecklats under de tre senaste läroplaner för den svenska skolan, Lgr80, Lpo94 och Lgr11, och genom undersökningen dra slutsatser som är kopplade till den tidigare forskningen. Målet med undersökningen är inte koppla till läroplanerna. Däremot vill jag se hur samhällets förändring har påverkat läroplanerna som i sin tur påverkar våra läromedel. Materialet som används i studien är sex svenska läromedel som har lånats från grundskolor i Jönköpings kommun. Genom analysen av materialet så framkommer det en tydlig utveckling av islam i de svenska läromedlen under tidsperioden 1982-2014. Islam får under 80-och 90-talet, framförallt under Lgr80, en negativ beskrivning som en ociviliserad och våldsbenägen religion där islam är bakom allt som sker i Mellanöstern. Under 2000-talet möter vi författare som försvarar religionen istället för att beskylla den, vissa så pass att nästan framställa islam som felfri. Islam skiljs nu åt från seder och traditioner som är kulturbaserade och som inte tillhör islam. Däremot är vissa författare fortfarande negativa och då till könsrollerna inom religionen. Under 2010-talet och Lgr11 möter vi författare som har en neutral ton emot islam. De försöker inte längre ta en ställning som föregående utan vill vara opartiska och visa på det positiva och negativa som existerar inom alla religioner. Genom studien framkommer även tydliga mönster mellan läromedlen som tillhör samma styrdokument, vilket visar på ett socio-religiöst perspektiv.

El presente trabajo consiste en dos estudios geológicos desarrollados de forma independiente en las islas del archipiélago Shetland del Sur, Antártica. El primero está enfocado en la caracterización y origen de la mineralogía secundaria de muy bajo-grado en la sucesión volcánica de Punta Hannah en Isla Livingston (ILi). El segundo en la comparación de la proveniencia sedimentaria de las rocas aflorantes en Cabo Wallace en Isla Low (ILo) con unidades similares en ILi y Península Antártica (PA). La sucesión volcánica andesito-basáltica del Cretácico Superior en Punta Hannah, presenta a una profusa ocurrencia de minerales secundarios de muy bajo-grado. Se encuentran presentes en amígdalas, vetillas, masa fundamental y fenocristales. Las plagioclasas primarias se encuentran alteradas a albita, ceolitas y calcita, mientras que los clinopiroxenos a filoslicatos máficos y menor celadonita. Difractometría de rayos-X y análisis de microsonda electrónica muestran la ocurrencia de filosilicatos máficos interestratificados entre clorita y esmectita trioctraédrica, así como también de las ceolitas: laumontita, heulandita, estilbita, clinoptilolita y faujasita. Los porcentajes de estratificados de clorita varían entre 57-84%. Las temperaturas de equilibrio en los filosilicatos máficos varían entre 160-190°C, los cuales están en conformidad con la temperatura estimada de 150-230°C para la asociación paragenética en ceolitas. Se estima que las condiciones barométricas en la paragénesis se encuentran entre los 600-1800 bars, que sugieren por lo menos 1km de erosión en la sucesión. La albitización de las plagioclasas primarias contribuyó a los fluidos ricos en Ca−Na, que deberían ser los precursores de las ceolitas ricas en Ca y de la calcita. La ocurrencia de los minerales secundarios en anillos periféricos en las amígdalas sugiere involucramiento de procesos de enterramiento, mientras que la presencia de vetillas cortando estas ocurrencias sugiere hidrotermalismo. Se reconocieron tres etapas paragenéticas: (1) celadonita/filosilicatos máficos, (2) ceolitas y (3) calcita. La Etapa (1) se habría formado durante el metamorfismo de enterramiento, mientras que las Etapas (2) y (3) durante el hidrotermalismo provocado por los sistemas geotermales en el régimen extensivo del Mioceno medio al Plioceno registrado en el archipiélago. La aquí definida Cuenca Wallace-Byers (CBB) consiste principalmente en una secuencia Jurásica sedimentaria-volcánica en el flanco oeste de la PA que aflora en los Estratos de Cabo Wallace (ECW) en la ILo y en el Grupo Byers en la ILi. Representa la evolución de un ambiente de sedimentación marino profundo en el Jurásico Superior a un ambiente volcánico a volcaniclástico que fue interrumpido por un episodio magmático en el Cretácico Inferior. La comparación de los diagramas de probabilidad relativa en las edades de los circones detríticos y el registro fósil de los ECW con la Formación Miers Bluff (FMB) y el Grupo Península Trinidad (GPT) no presenta correlación concluyente. El peak Pérmico tardío en los circones detríticos de ECW indica un evento levemente más joven que el registrado en las fuentes Pérmicas de GPT y FMB. Los 100 Ma entre la edad de cristalización Valanginiana de la Granodiorita de Cabo Wallace y el peak Pérmico tardío, que son respectivamente la edad mínima y máxima de sedimentación de los ECW, representan un considerable retrabajo sedimentario debido probablemente a alguna barrera geográfica que no permitió adiciones sedimentarias a los ECW de los plutones Jurásicos ubicados en la PA. Los ECW indican que en las latitudes de ILo, los complejos turbidíticos habrían continuado durante el Triásico y parte del Jurásico a lo largo del margen continental activo al oeste de la PA septentrional.

Full textAbstract:
Islam är en av världsreligionerna och har miljoner anhängare världen över. Det finns en allmän uppfattning om islams problematik, så till vida att islam sällan får rätt presentation, då exempelvis inom massmedia och skola. Frågan är hur skolan, som är vårt största lärosäte presenterar en religion rättvist och utan fördomar, hur en religion blir presenterat på ett icke nyanserat sätt.
Uppsatsens syfte är att söka svar på hur islam framställs i svensk gymnasieskola, med metoder som dokumentstudier, fokusgrupp och djupintervjuer, där muslimska elever berättar om erfarenheter och upplevelser.
Generella slutsatser som framkommit är att muslimska elever anser att svensk gymnasieskola ger en delvis positiv bild av islam, som religion, men med vissa brister, såsom etnocentriskt tänkande, i muntlig presentation och text. Elever har även pekat på en viss marginalisering och distansering gällande islams presentation i undervisningen.
Islam is one of the religions in the world and has millions of followers around the world. However, it has been argued that Islam rarely gets portrayed impartially in for example mass media and education. The objective of this essay is to understand how Swedish Muslim high school students experience the presentation of Islam in religious education. Empirical data have been collected by means of analysis of textbooks, focus group interview and one- to- one in-depth interviews. Principal findings of the study suggest that Swedish Muslim high school students consider that, in general, Islam gets portrayed fairly in religious education. However, the shortcomings pointed out by the students included in the study of religious education, in terms of how Islam is portrayed, are ethnocentricity as well as marginalisation and dissociation.

Full textAbstract:
The relationship between religion and development is a relatively new research area, complicated by the arguably "secular reductionism" and "materialistic determinism" of mainstream development theory and practice. Against this backdrop, this doctoral study examines the relationship between Islamic and mainstream development discourses, analysing the complex power relations at work within the discursive practices of the development field through a conceptual apparatus comprised of a Foucauldian notion of power and discourse and a Laclauan view of hegemony. The objective of this study is to develop a better understanding of how Islamic development policy making and makers have made meaning of the central issues of development and progress as expressed in the body of theory and practice that makes up the development field. Interestingly, Islamic thinkers were already criticising the Euro-centric nature of the development discourse in the 1950s and 60s. They proposed an Islamisation of knowledge, particularly in the field of economics, as a way of overcoming a perceived Western‘ domination. In pursuit of the question as to how "Islam" relates to the issue of development and progress, this thesis explores the genealogy of the mainstream and the Islamic development discourses, illustrated by a selected case study within the development field in Bangladesh.

Full textAbstract:
Thesis (MScMedSc)--Stellenbosch University, 2015.ENGLISH ABSTRACT: Diabetes Mellitus is a metabolic disease characterized by the loss of beta cells from the islets, thereby disrupting islet composition and architecture which are important components that influence islet function. The experimental technique of pancreatic duct ligation (PDL), which is thought to induce the regeneration of beta cells within the adult pancreas, was investigated as a novel treatment strategy for diabetes. This study aimed at investigating the possibility that the PDL model may have the capacity to restore normal islet composition and architecture in diabetic animals, which could make it an effective approach to reverse diabetes. Male Wistar rats (n=55) were divided into three study groups: the normal control (NC) group, the diabetic control (DC) group consisting of five subgroups (day 0, 3, 5, 10 and 30) and the experimental (EX) group consisting of four subgroups (day 3, 5, 10 and 30). The experimental group was exposed to PDL. All pancreata were divided into a P1 portion (proximal to the point of ligature) and P2 portion (distal to the point of ligature) for histological assessment. Animals’ non-fasting blood glucose levels (BGLs) and body weights were monitored. The general morphology of the tissue was studied, while an immunohistochemical (IHC) study was performed to determine insulin, pancreatic polypeptide, glucagon and somatostatin protein expression in the P1 and P2 portions of the pancreas. From the IHC slides hormone fractions, staining intensity and distribution were determined as indication of islet composition and architecture. Despite apparent morphological recovery in the islet 30 days post-PDL, islet composition and architecture remained disrupted. Compared to diabetic animals, the proximal portion of the pancreas in experimental animals had a decreased beta cell fraction and increased delta cell fraction thirty days following PDL. These observed changes in islet composition in the part of the pancreas proximal to the ligature are novel findings. There was no change in the diabetic islet composition in the portion of the pancreas distal to the ligature thirty days following PDL. Furthermore, pancreatic duct ligation did not restore body weight or normoglycemia. We conclude that STZ disrupts islet composition and architecture and this could not be restored using PDL; we therefore suggest that a comparative study using a Type 2 diabetic model, where there is limited damage to pre-existing beta cells, may yield different results.
AFRIKAANSE OPSOMMING: Diabetes Mellitus is ʼn metaboliese siekte wat deur die verlies van beta selle uit die eilande van Langerhans gekarakteriseer word. Hierdie verlies van beta selle ontwrig eiland komposisie en argitektuur, twee belangrike komponente van eiland funksie. Die eksperimentele tegnieke van pankreatiese buisafbinding (in Engels PDL), wat moontlik beta sel regenerasie in die volwasse pankreas kan induseer, is ondersoek as behandelings-strategie vir diabetes. Hierdie studie het ten doel gehad om die moontlikheid te ondersoek dat die PDL model die kapasiteit het om normale eiland komposisie en argitektuur te herstel in diabetiese diere, wat dit ʼn effektiewe benadering vir die omkeer van diabetes kan maak. Manlike Wistar rotte (n=55) was in 3 studie groepe verdeel: die normale kontrole (NC) groep, die diabetiese kontrole (DC) groep wat uit vyf subgroepe bestaan (dag 0, 3, 5, 10 en 30) en die eksperimentele (EX) groep wat uit vier subgroepe bestaan (dag 3, 5, 10 en 30). Die eksperimentele groep is aan PDL blootgestel. Alle pankreata is verdeel in ʼn P1 porsie (proksimaal tot die afbinding) en ʼn P2 porsie (distaal tot die afbinding) vir histologiese assessering. Die diere se nie-vastende bloed glukose vlakke en liggaamsgewig is gemonitor. Die algemene morfologie van die pankreas weefsel is bestudeer, terwyl ’n immunohistochemiese (IHC) studie gedoen is om insulien, pankreatiese polipeptied, glukagon en somatostatien proteïen uitdrukking in die P1 en P2 porsies van die pankreas te bepaal. Vanaf die IHC snitte is hormoon fraksie, kleur intensiteit en verspreiding bepaal as aanduidings van eiland komposisie en argitektuur. Ten spyte van ooglopende morfologiese herstel in die eilande op dag 30 na PDL, het eiland komposisie en argitektuur versteur gebly. In vergelyking met die diabetiese diere, het die proksimale deel van die pankreas van eksperimentele diere verlaagde beta sel fraksie en verhoogde delta sel fraksie getoon dertig dae na PDL. Die waarneming van veranderde komposisie in die deel van die pankreas proksimaal tot die afbinding is nuut. Daar was geen verandering in diabetiese eiland komposisie in die deel van die pankreas distaal tot die afbinding dertig dae na PDL nie. Verder het PDL nie liggaamsgewig of bloedsuiker genormaliseer nie. Ons gevolgtrekking is dat STZ eiland komposisie en argitektuur ontwrig en dat dit nie met PDL herstel kon word nie; daarom stel ons ʼn vergelykende studie in ʼn tipe 2 diabetes model voor, waar die skade aan reeds bestaande beta selle beperk is, wat ander resultate mag lewer.

Full textAbstract:
This thesis focuses on enteroviral effects on human pancreatic islets. Most knowledge of viral effects on host cells relies on studies of immortalized cell lines or animal models. The islets represent a fundamentally different and less well studied cellular host. Also, enterovirus has been implicated in the etiology of type 1 diabetes (T1D). We show that when enterovirus replicates in human islets it activates innate immunity genes and induces secretion of the chemokines MCP-1 and IP-10. An important difference in activation of innate immunity by replicating EV and synthetic dsRNA is suggested, since the chemokine secretion induced by EV infection but not by dsRNA is reduced by female sex hormone. We also demonstrate a direct antiviral effect of nicotinamide, and even though this substance failed to prevent T1D in a large-scale study, this finding could have implications for the treatment/prevention of virus- and/or immune-mediated disease. We also had access to human pancreata from two organ donors with recent onset T1D and several donors with T1D-related autoantibodies, which gave us the opportunity to study ongoing pathogenic processes at and before the onset of T1D. Despite this, we could neither confirm nor reject the hypothesis that EV is involved in T1D development. Several observations, such as ultrastructural remodeling of the beta cell, activation of innate immunity, and immunopositivity to EV capsid protein 1, supported an ongoing virus infection, but direct evidence is still lacking. An interesting finding in the donors with recent onset T1D was that the islets were positively stained for insulin, but did not secrete insulin in response to glucose-stimulation. A similar effect was observed in EV-infected islets in vitro; EV destroyed islet function and insulin gene expression, but the islets still stained positive for insulin. This may be indicative of that a functional block in addition to beta cell destruction is involved in T1D pathogenesis. In conclusion, these studies of EV in isolated human islets in vitro support that this virus can cause T1D in vivo, but future studies will have to show if and how frequently this happens.

Full textAbstract:
Trinity, East, and Wine Islands make up the eastern half of the Isles Dernieres barrier arc in south-central Louisiana. Formed following the abandonment of the Lafourche delta complex, subsidence and storm erosion have led to rapid deterioration of the system. Since 1887, the land area of the islands has decreased seventy-seven percent, and the gulf shoreline has retreated landward more than a kilometer. Wave ravinement on the shoreface of the islands is responsible for the most sediment loss; liberated sediment travels longshore to tidal inlets. The dominant ebb tidal currents then transport the sediment to where it is deposited in ebb tidal deltas or carried to the west, out of the system. A large lobe of sediment bypassing Cat Island Pass is entering the system from the eastern lower shoreface, which helps replace some of the sediment lost through wave ravinement to the upper shoreface.

Full textAbstract:
GeólogaLa Península Fildes se encuentra ubicada al suroeste de la Isla King George, la cual forma parte de las Islas Shetland del Sur, al norte de la Península Antártica. Este conjunto de islas corresponde a un arco volcánico generado desde el Mesozoico tardío hasta la actualidad, sufriendo regímenes de compresión y extensión. En la península se depositaron en su mayoría lavas basálticas y andesítico-basálticas, brechas volcanoclásticas y tobas, asociados a dos episodios de actividad volcánica desde el Paleoceno al Eoceno. Los centros eruptivos, por su parte, sufrieron un desplazamiento gradual de suroeste a noreste y los intrusivos subvolcánicos se distribuyeron regularmente a lo largo de fallas de orientación NOO-SEE. Bajo este contexto, se generaron minerales secundarios tales como ceolitas, esmectita, clorita, epidota, pumpellyita, calcedonia y calcita, los cuales se distribuyen a lo largo de toda la península, afectando principalmente a lavas amigdaloidales con mayor permeabilidad. De acuerdo a la mineralogía descrita, se observó una tendencia en el grado metamórfico, el cual aumenta hacia el este. Por otro lado, esta relación no se produjo con la estratigrafía. Las temperaturas alcanzadas no superan los 230ºC, infiriéndose presiones bajas, debido al poco espesor de los miembros y formaciones en cuestión. La presencia de áreas con mineralogía secundaria característica de metamorfismo de bajo grado, sugiere la ocurrencia de un metamorfismo de enterramiento al cual se sobre impuso un metamorfismo hidrotermal. Este último se habría producido por la acción de sistemas geotermales generados luego del cese de la subducción relacionada al volcanismo (Mioceno medio) y durante el volcanismo asociado a extensión (Mioceno medio-Plioceno) en las Islas Shetland del Sur. Sin embargo, la fuente termal responsable no está totalmente clara. Esta alteración, debido a las similitudes con Neuhoff et al. (1999) se habría producido en tres episodios metamórficos: 1º con precipitación de celadonita, calcedonia y clorita-esmectita y 2º con precipitación de ceolitas y 3º con formación de calcita.

Full textAbstract:
Type 1 and 2 Diabetes Mellitus are a growing health problem throughout the world. There is an increasing need for methodologies, which are both reliable and non-invasive to measure the amount of insulin-producing tissue (Beta-cell mass, or BCM), as well as rapidly quantify changes in the BCM due to the onset of disease, beta-cell replacement therapy, or other treatments. Positron Emission Tomography (PET) is a non-invasive, quantitative functional imaging technique which can be used to study dynamical or static processes inside the body. In this thesis, we present a study protocol for in vivo imaging of the most common form of beta- cell replacement therapy; islet transplantation. Islets were labeled with the PET tracer, 2-deoxy-2[18F]fluoro-D-glucose ([18F]FDG), and administered intra-portally, while the recipient was monitored by PET/CT. The hepatic distribution of the islets was highly heterogeneous, and around 25% (human) or 50% (porcine) of the administered islets could not be found in the liver after completed transplantation, confirming previous reports of considerable cell injury during the procedure leading to low hepatic engraftment. Native BCM in the pancreas can potentially be quantified using a PET tracer with sufficiently high specificity, but the major obstacle is the relative low amounts of insulin producing tissue (only 1-2% of the pancreatic volume). Two tetrabenazine analogues, [18F]FE-(+)-DTBZ and [18F]FE-(+)-DTBZ-d4, are ligands to VMAT2, which is expressed in islet tissue. Both analogues were investigated and characterized as potential BCM imaging agents both in vitro and in vivo. Both tracers exhibited high preferential binding to islet tissue compared to exocrine pancreatic tissue. However, the specificity was not high enough to overcome the obscuring exocrine signal in vivo (7-10% of the signal originating from specific islet tracer uptake). This thesis demonstrates that it is possible to quantitatively assess islet transplantation by PET imaging. In vivo determination of native pancreatic BCM is, in theory, possible with both [18F]FE-(+)-DTBZ and [18F]FE-(+)-DTBZ-d4, but tracer analogues with higher islet specificity is needed for quantification of smaller BCM changes with physiological impact.

Full textAbstract:
Tybee Island is a tiny piece of land, only-two-and-a-half miles long and two-thirds of a mile wide; however, its strategic location near the mouth of the Savannah River assigned to it an important role in the birth and history of the state of Georgia. Over this coastal community five flags have flown, representing Spain, France, England, the Confederate States of America, and the United States of America. Using numerous vintage photographs from the archives of the Tybee Island Historical Society, Tybee Island guides the reader through over two hundred years of history. Although much of its history is linked to nearby Savannah, Tybee is singular among Georgia’s coastal islands, and has a history and lore that is uniquely its own. This visual journey begins with the building of Georgia’s oldest and tallest lighthouse, and continues through Tybee’s involvement in the Civil War. Also covered are the island’s later roles as a military installation, a popular coastal resort, and a residential community. Vintage photographs recall earlier days on Tybee, when the island was known as “Ocean City,” “Savannah Beach,” and, to some, “the best kept secret on the East Coast.”https://dc.etsu.edu/alumni_books/1029/thumbnail.jpg

Being able to volley ideas and rewrite the text established many themes that would be explored as music later on. I refer to the five movements in the piece as a monologue because it is intended as a single dramatic statement. The libretto offered a bounty of opportunities to compose music with the intention of adding a particular perspective to a given text. I specifically tried to keep the performance in mind while composing, attempting to support the vocalist dramatically with the quartet material, in general, I tried to make a piece in which the text and the music are mutually supportive. In a sense, a major goal of mine was to let the text drive the music to places it would otherwise not have gone. The challenge of experimenting with new ideas in composition while striving to best represent a desired dramatic effect or scenario has proved itself to be a fruitful way of finding fresh material with purpose and character Misery Island was premiered at the Boston University Concert Hall on April 8, 2013, with Katrina Galka singing, Nelli Jabotinsky and Hyunji Kim on violin, Evan Perry on viola, Robert Mayes on violoncello, and the composer conducting.

Full textAbstract:
L’étude des manifestations génères par l'islam dans le champ des relations internationales contemporaines permet de mettre en exergue deux phénomènes de grandes amplitudes : le dédoublement de la scène internationale, qui se voit dorénavant animée par deux sortes d'acteurs, et la nécessite d'une véritable démocratie mondiale basée sur le profond respect d'autrui. Les relations internationales classiques, intervenant traditionnellement entre états ou organisations interétatiques, se trouvent progressivement juxtaposées aux relations transnationales, c'est-à-dire de relations mettant en jeu des personnes privées qui deviennent elles aussi des acteurs sur la scène internationale. Agissant au delà du cadre du territoire de l’état dont ces personnes ressortissent, elles questionnent amplement la souveraineté de l'entité étatique. Les différents flux génères par l'islam permettent d'illustrer intensément un tel phénomène. Ils montrent les tentatives d'émancipation des individus face a la puissance étatique et comment ceux-ci la combattent, la contournent ou, tout simplement, l'ignorent. Dans la majeure partie des cas, l'état perçoit les flux transnationaux comme une menace ; l'étude des réseaux islamistes le démontre amplement. Cela dit, une analyse plus approfondie tend à révéler que ce sont bien les relations transnationales des musulmans en général, et non des islamistes en particulier, qui sont ressenties comme une menace. Or, la réflexion menée à propos des manifestations contemporaines de l'islam en général, et du phénomène de l'islam politique en particulier, peut montrer que les éléments, perçus par ailleurs négativement, de ces manifestations constituent les symptômes d'un très grave malaise. À la lumière d'une analyse sociologique, ces manifestations, même et surtout les plus violentes, ainsi que toute la thématique islamiste, deviendraient cohérentes et significatives. Dans la perspective du maintien et de la consolidation de la paix à un niveau mondial, il serait donc urgent de prendre en compte une telle vision de l'islam.

Full textAbstract:
Results of extensive site reconnaissance on the Isles of Tiree, Coll and north-west Mull, Inner Hebrides are presented. Pollen-stratigraphic records were compiled from a profile from Glen Aros, north-west Mull and from two profiles on Coll located at Loch an t-Sagairt and Caolas an Eilean. Quantification of microscopic charcoal provided records that were used to facilitate a preliminary evaluation of the causal driving mechanisms of vegetation change. Bayesian modelling of radiocarbon dates was used to construct preliminary chronological frameworks for these records. Basal sedimentary deposits at Glen Aros contain pollen records that correspond with vegetation succession typical of the early Holocene dating to c. 11,370 cal BP. Woodland development is a key feature of the pollen records dating to the early Holocene, while records from Loch an t-Sagairt show that blanket mire communities were widespread in north-west Coll by c. 9800 cal BP. The Corylus-rise is dated to c. 10,710 cal BP at Glen Aros and c. 9905 cal BP at Loch an t-Sagairt, with records indicating extensive cover of hazel woodland with birch. All of the major arboreal taxa were recorded, though Quercus and Ulmus were nowhere widespread. Analysis of wood charcoal remains from a Mesolithic site at Fiskary Bay, Coll indicate that Salix and Populus are likely to be under-represented in the pollen records. Reconstructed isopoll maps appear to underplay the importance of alder in western Scotland during the mid-Holocene. Alder-rise expansions in microscopic charcoal dating to c. 7300 cal BP at Glen Aros and c. 6510 to 5830 cal BP on Coll provide records of significance to the issue of human-induced burning related to the expansion of alder in Britain. Increasing frequencies in microscopic charcoal are correlated with mid-Holocene records of increasing aridity in western Scotland after c. 7490 cal BP at Glen Aros, 6760 cal BP at Loch an t-Sagairt and 6590 cal BP at Caolas an Eilean, while several phases of increasing bog surface wetness were detected in the Loch an t-Sagairt archive during the Holocene. At least five phases of small-scale woodland disturbance during the Mesolithic period were identified in the Glen Aros profile dating to c. 11,650 cal BP, 9300 cal BP, 7840 cal BP, 7040 cal BP and 6100 cal BP. The timing of the third phase is coincident with evidence of Mesolithic settlement at Creit Dhu, north-west Mull. Three phases of small-scale woodland disturbance were detected at Loch an t-Sagairt dating to c. 9270 cal BP, 8770 cal BP and 8270 cal BP, all of which overlap chronologically with evidence of Mesolithic activity at Fiskary Bay, Coll. A number of these episodes are aligned chronologically with phases of Holocene climate variability such as the 8.2 K event.

Full textAbstract:
Renewable energy potential at a local level is important if communities are to play a role in the wider global energy transition. The following thesis studies the ongoing transition on the island of Lewis and Harris, part of the Western Isles, Scotland. A PLEXOS energy model is constructed, focusing on the island’s electricity system. Future local renewable potential is investigated through several scenarios. Electrification of heating and transportation sectors is assumed, via high uptake of heat pumps and electric vehicles, as the replacement of the failed subsea mainland interconnection and the future of the island’s diesel power station are explored. Battery energy storage systems provide a potential solution to the decommissioning of the diesel power station, coupled with additional solar photovoltaics to complement already installed wind resources. The importance of interconnection capacity is highlighted if the island is to become a major exporter of wind power, although through sensitivity analysis it was found that the economic viability of new wind turbines is uncertain due to falling mainland electricity prices. The representation of the mainland is identified as a key limitation within the study, in particular the projection of future electricity prices and their potential temporal relationship with local wind production. Greater consideration here would be beneficial. Expansion of the modelling to include heating demands at a wider level, alongside potential hydrogen production, could be interesting areas to explore further.Förnybar potential på lokal nivå är viktig om energisamfund ska kunna spela en roll i den bredare globala energiövergången. I denna avhandling undersöks den pågående energiövergången på ön Lewis och Harris, som är en del av de Yttre Hebriderna (eng. Western Isles) i Skottland. En PLEXOS-energimodell konstrueras med fokus på öns elsystem och den framtida lokala potentialen för förnybar energi undersöks genom flera scenarier. Elektrifiering inom uppvärmnings- och transportsektorn uppskattas, genom en storökning av värmepumpar och elfordon, för att undersöka en ersättnings möjlighet till den misslyckade undervattenskabeln till fasta Skottland och framtiden för öns dieselkraftverk utvärderas. Batterilager är en möjlig lösning för avveckling av dieselkraftverket, tillsammans med ytterligare solceller för att komplettera den redan installerade vindkraften. Vikten av överföringsmöjligheter till fastlandet betonas om ön skulle komma att bli en stor exportör av vindkraft, även om det genom känslighetsanalysen konstateras att den ekonomiska bärkraften hos nya vindturbiner är osäker på grund av sjunkande elpriser på fastlandet. Representationen av fastlandet har identifierats som en nyckelbegränsning i studien, särskilt prognosen för framtida elpriser och dess potentiella samband med lokal vindkraftsproduktion. Detta är ett område som skulle kunna vidareutvecklas. Att utvidga modelleringen till att omfatta uppvärmning på en bredare nivå, tillsammans med eventuell vätgasproduktion, skulle kunna vara intressanta områden att utforska ytterligare.

Full textAbstract:
Diabetes Mellitus is a group of complex and heterogeneous metabolic disorders characterized by hyperglycemia. Even though the condition has been extensively studied, its causes and complex pathologies are still not fully understood. The occurring damage to the pancreatic islets is strikingly heterogeneous. In type 1 diabetes, the insulin producing beta cells are all destroyed within some islets, and similarly in type 2 diabetes, some islets may be severely affected by amyloid. At the same time other islets, in the near vicinity of the ones that are affected by disease, may appear fully normal in both diseases. Little is known about this heterogeneity in susceptibility to disease between pancreatic islets. This thesis examines the physiological and pathophysiological characteristics of islet subpopulations. Two subpopulations of islets were studied; one constituting highly vascularized islets with superior beta cell functionality, and one of low-oxygenated islets with low metabolic activity. The highly functional islets were found to be more susceptible to cellular stress both in vitro and in vivo, and developed more islet amyloid when metabolically challenged. Highly functional islets preferentially had a direct venous drainage, facilitating the distribution of islet hormones to the peripheral tissues. Further, these islets had an increased capacity for insulin secretion at low glucose levels, a response that was observed abolished in patients with recent onset type 1 diabetes. The second investigated islet subpopulation, low-oxygenated islets, was found to be an over time stable subpopulation of islets with low vascular density and beta cell proliferation. In summary, two subpopulations of islets can be identified in the pancreas based on dissimilarities in vascular support and blood flow. These subpopulations appear to have different physiological functions of importance for the maintenance of glucose homeostasis. However, they also seem to differ in vulnerability, and a preferential death of the highly functional islets may accelerate the progression of both type 1 and type 2 diabetes.

Full textAbstract:
Los sistemas de rift en configuraciones volcánicas, se encuentran relacionadas con crecimiento de grandes edificios volcánicos y se definen como áreas de la corteza sometidas a esfuerzos extensivos que generan fracturas en forma de fisuras a través de las cuales se emite lava. Los grupos de fisuras delinean los sistemas de rift.
Tradicionalmente, los sistemas de rift han sido considerados áreas de la superficie terrestre que actúan a modo de conductos profundos que enlazan las zonas de generación del magma en el manto y corteza inferior con la superficie terrestre, canalizando y controlando el ascenso de los magmas de manera directa. Algunos estudios recientes basados en datos geológicos, geofísicos y paleomagnéticos cuestionan dicho enraizamiento profundo, considerando por el contrario un origen más superficial. Dicho origen estaría asociado tanto a la tectónica regional como a procesos locales relacionados con las variaciones en la carga gravitatoria durante el proceso de desarrollo de los edificios volcánicos.
Con el objetivo de contribuir al conocimiento de estos sistemas hemos elegido estudiar los sistemas de rift de Tenerife y El Hierro, ambas situadas en el Archipiélago Canario. Ambas, ofrecen la oportunidad de llevar a cabo un estudio de este tipo a la vista de sus características superficiales. Morfológicamente, estas islas presentan lo que en apariencia serían tres zonas de rift cada una, también denominadas «dorsales». En superficie, ambas islas muestran una disposición similar de su volcanismo basáltico a lo largo de estás dorsales, habiéndose propuesto tradicionalmente una configuración de triple rift en cada isla.
Con el fin de obtener una imagen interna de los sistemas de rift tanto en Tenerife como en el Hierro, se desarrollaron modelos tridimensionales de contrastes de densidad del subsuelo. Estos modelos fueron obtenidos mediante la aplicación de un algoritmo genético de inversión gravimétrica que emplea como parámetros de entrada los datos de las anomalías gravimétricas. Dichas anomalías fueron calculadas a través del análisis de una gran cantidad de datos de gravedad terrestre provenientes de distintas fuentes de datos, incluidos datos recogidos expresamente para la densificación de valores de gravedad en las áreas de estudio.
Son estos modelos finales, los que hemos empleado como la base sobre la que argumentar las posteriores discusiones. El modelo obtenido para la isla de El Hierro, apunta en este caso, a que los sistemas de rift, son estructuras poco enraizadas, las cuales estarían originadas a pocos kilómetros de la superficie, siendo su configuración controlada por una combinación de la tectónica regional y por procesos extensivos tanto de carga como de inestabilidades gravitatorias. Estas estructuras, serían utilizadas para facilitar el transporte lateral del magma una vez que este alcanzara los niveles más superficiales de la corteza.
El modelo tridimensional obtenido para la dorsal noroeste de la isla de Tenerife, sugiere una estructura análoga a la anterior, un origen superficial de estos sistemas de rift. En cambio, la comparación entre los modelos correspondientes a la estructura bajo dicha dorsal y la estructura del subsuelo correspondiente a la parte sur de la isla, señala claras diferencias entre ambas. Esto señala a que el origen de ambas es distinto y, por tanto, el modelo volcánico de la parte sur de la isla estaría más en correspondencia con un campo volcánico monogenético que con una configuración típica de rift, como ya había sido sugerido en trabajos previos.Rift systems in oceanic volcanic areas are related to the growth of large volcanic buildings and are defined as areas of the crust subjected to extensive stresses that generate fractures in the form of fissures through which lava is emitted. The groups of cracks delineate rift systems. Traditionally, they have been considered deep structures acting as conduits that connect the areas of magma generation in the mantle with the earth's surface, controlling the magma rise in a way direct. Some recent studies based on geological, geophysical and paleomagnetic data question this deep rooting, considering instead a shallower origin. This origin would be associated with both regional tectonics and local processes related to variations in the gravitational load during the development process of volcanic buildings. In order to increase the knowledge of these systems we have studied the rift systems of Tenerife and El Hierro, both located in the Canarian Archipelago. Both, offer the opportunity to carry out a study of this type in view of its surface characteristics. Morphologically, these islands present three potential zones of rift, also denominated "dorsales". In surface, both islands show a similar arrangement of their basaltic volcanism along these “dorsales”, having traditionally been proposed a triple rift configuration in each island. We built an internal image of the Tenerife and El Hierro rift systems based in 3D models of subsoil density contrasts. These models were obtained by the application of an inversion genetic algorithm based on gravity data which uses as input parameters gravimetric anomalies. These models are the basis on which we will develop the subsequent discussions. The model obtained for the El Hierro Island, the rift systems are poorly rooted structures. They would have a shallower origin. Moreover, the three-dimensional model obtained for the north- western ridge of the island of Tenerife suggests a structure similar to the previous one, a superficial origin of these rift systems. In contrast, the comparison between the models corresponding to the structure under the “dorsal” and the subsurface structure corresponding to the southern part of the island, shows clear differences between the two. This indicates that the origin of both is different and, therefore, the volcanic model of the southern part of the island would be more in correspondence with a monogenetic volcanic field than with a typical configuration of rift, as already had been suggested in previous works.

A clear discontinuity with the larger city of New York and with the present community exists at the site. Accepting the fragmentation and aggregation (the unfinished quality) of the existing context represents the beginning of the design process. Promoting diversity, evoking sensuality through form and materiality and promoting a sense of heterogeneity will be interfused with the existing discontinuity. The design process shall be committed to a changing role in types and degrees of a variety of generative sources, depending on the relationships of these factors that arise when addressing the specific problem. All of the possible generative sources will be developed and assigned equal weight, developing numerous architectural elements or fragments. A temporary strategy requiring flexibility as to the role and the degree of influence of each of the sources will be developed and defined, Through these operations, a catalogue of inclusive solutions were made available and fused to produce a rational and calibrated design attitude. A programming and formal strategy evolved through discovery rather than irnplementation. Diagramming exercises mapping circulation, form plausibility, existing arid expected context and the hybrid program was developed with wellness as the point of programmatic departure. Reflecting both fact/science or tangible (subtly fixed generative) and intuition/idiosyncrasy or intangible (element of contradicting generative) the diagramming establishes points of formal/spatial departure. The design process will focus on a continuous matrix of architecture mediating between 'built' and 'found.' The built can be explained as that which dominates the sky or air.

Full textAbstract:
Barrier islands include some of the most endangered and fragmented ecosystems on the Atlantic coast, providing critical habitat for many species, including some that are threatened and endangered. As the vast majority of these islands have been developed for human usage study and protection of the few remaining undeveloped and undisturbed islands is critical. This study was undertaken in order to characterize the vascular plant communities on Bird Island, an uninhabited, undeveloped barrier island on the border of North and South Carolina, with the objectives of a thorough survey of flora, vegetation, and environment, classification of plant communities, and multivariate analysis of vegetation and environmental data. A floristic inventory of the island and its associated marshes was conducted during the growing season (May-November) of 2002 and 2003. One hundred four 100m2 plots were inventoried for vegetation and environment using protocols developed by the Carolina Vegetation Survey. Plant communities were identified according to the National Vegetation Classification, the Classification of the Natural Communities of North Carolina, and the Carolina Vegetation Survey. Interpretation of vegetation patterns was based on multivariate analysis of vegetation and environmental data. Ninety-one vascular plant species in 35 families, including 4 exotic species, were distributed across 12 communities. Communities on Bird Island appear to be distinctive when compared to those described for other barrier islands in the region. Additionally, the vegetation survey on Bird Island revealed suitable habitat for the federally listed Seabeach amaranth (Amaranthus pumilus); an important dune-building annual of the North American Atlantic coast. Surveys of the late 1980s and early 1990s documented small populations of Seabeach amaranth on Bird Island, but our work found no indication of a population in either 2002 or 2003. Seabeach amaranth?s existence range-wide is threatened by habitat loss and fragmentation, herbivory, and anthropogenic disturbances such as beach driving, hardening, and raking. Published work on this species has been limited, but observations of natural, experimental, and restored populations have indicated relationships between distance from the ocean and both survivorship and reproduction. To quantify this relationship, 314 plants were transplanted at varying distances from the ocean. Plants were monitored monthly from June until December 2003. We found that distance from the ocean had a significant effect on survivorship, size, and reproduction; however, presence of webworms and ghost crabs did not have significant effects on size or reproduction. Distance from the ocean combined with complex factors such as over wash and soil salinity appear to be important indicators of success for both natural and restored populations of this species, and landscape position should be incorporated into future conservation and restoration efforts for A. pumilus in the Carolinas and elsewhere. Overall, we found that the vegetation of Bird Island is mostly intact, with few exotic, invasive species present. Bird Island?s protected status and limited presence of invasive species make it suitable habitat for continued protection and further restoration of rare, threatened, or endangered species, such as Seabeach amaranth. Atlantic barrier islands in general provide distinct community types combined with a small species pool, a combination that may provide a model for examination of larger ecological questions.
