Ett våldtäktsanklagat varumärke : En kristisk diskursanalys av porträtteringen av Wikileaks och Julian Assange i svensk dagspressEllsäter, Åsa January 2013 (has links)
Uppsatsens syfte är att undersöka ifall och om så även hur Wikileaks och Julian Assange porträtteras före och efter de våldtäktsanklagelser mot Assange som offentliggjordes i augusti 2010. I den diskursanalys som genomförs granskas sex nyhetsartiklar som valts ut efter bestämda tidsaspekter men i övrigt slumpmässigt. Artiklarna har publicerats i Dagens Nyheter och släppts från TT. Analysen bygger delvis på en ram lagd av teoretikerna Ernesto Laclau och Chantal Mouffe, och på teori och metodik beskriven av Norman Fairclough, och som handlar om att sätta diskursiva praktiker i samband med social och kulturell utveckling. Analysen är komparativ och fokuserar på det retoriskt diskursiva. Undersökningen visar att det finns en diskrepans mellan språkbruket i de artiklar som publicerats innan 2010 och de som publicerats efter tidpunkten. Det visar sig också vara så att Julian Assange och Wikileaks kopplas samman i större utsträckning före och efter 2010. Den största förändringen i språkvalet är ett större ifrågasättande av trovärdighet och motiv för materialsläpp vad gäller Wikileaks, som går parallellt med en beskrivning av Assange som blir allt mer opersonlig efter 2010. Organisationen fortsätter att vara en källa för DN och TT men i synnerhet deras motiv och trovärdighet ifrågasätts.

Screen printable sacrificial and structural pastes and processes for textile printingWei, Yang January 2013 (has links)
This thesis presents a new approach for fabricating free standing structures on flexible substrates using the screen printing technique. The research addresses electronic textile applications and is intended to provide a new method for realising sensors and complex structures on fabrics. Conventional smart fabric fabrication methods, such as weaving and knitting, are only able to achieve planar structures with limited functionality. Packaged discrete sensors can also be attached directly to fabrics but this approach is unreliable and unsuitable for mass production. The reported materials and the fabrication processes enable free standing structures to be formed by printing functional layers directly on top of the fabric. This reduces the fabrication complexity and increases wearer comfort and the flexibility of the fabric. This research details an investigation into sacrificial materials suitable for use on fabrics. A plastic crystalline material (Trimetlylolethane (TME)) was identified as an appropriate sacrificial material because it sublimates which reduces the chance of stiction occurring. A screen printable TME paste has been achieved by dissolving TME powder in a solvent mixture of cyclohexanol (CH) and propylene glycol (PG). The TME sacrificial paste can be cured at 85 oC for 5 minutes providing a solid foundation for subsequent printed layers. This sacrificial layer can be removed in 30 minutes at 150 oC leaving no residue. EFV4/4965 UV curable dielectric material was identified as an appropriate structural material for use with TME. The feasibility of the sacrificial and structural materials has been demonstrated by the fabrication of free standing cantilevers and microfluidic pumps on fabrics and flexible plastic films. Printed cantilevers, with capacitive and piezoelectric sensing mechanisms, have been demonstrated as human motion sensors. A printed microfluidic pump with a maximum pumping rate of 68 μL/min at 3 kHz has also been demonstrated. Both the cantilever and micropump have been demonstrated, for the first time, on fabrics and polyimide substrates, respectively.

Cloth in action : the transformative power of cloth in communitesBarber, Claire January 2015 (has links)
The work submitted for the PhD by Publication is evidence of my investigation into the significance of textiles as an aesthetic experience within a socially engaged form of material practice, some of which involves other people. Social engagement has been an active and deliberate agent in the aesthetic transformation of functional material objects in two of my publications called The Sleeping Bag Project and You Are the Journey. A third publication is a co-edited book called Outside: Activating Cloth to Enhance the Way We Live. A range of essays by artists, curators and writers discloses previously unwritten commentaries on community initiatives that probe a range of empathetic modes of investigation that explore meaningful spaces for participation. I have come to recognise that a proactive attitude towards collaboration is evident in all three publications. It is exemplified by my approach to co-orchestrating the Outside book and by an eagerness to work with others to advance the concept of the transformative power of cloth within the live arena for socially engaged textile practices today. The relations between an aesthetic transformation and socially engaged practice was implicit in Rozsika Parker’s seminal text The Subversive Stitch first published in 1984 providing an analysis of textiles within social history. At the beginning of work on this PhD my relationship with the book was complex and full of tensions. My perceptions of Parker’s work changed as I discovered at the very end of my thesis connections between her work and mine that enable a deeper understanding of the need in my socially engaged textile practice today for the kind of aesthetics she describes historically as arising from social constraint. Consequently The Subversive Stitch has now re-appeared with value as a touchstone for my work in a contemporary context. The thesis then discusses examples of the outcomes of practices by other artists and considers the attention given to visual aesthetics within socially engaged practices. Ideas are developed to suggest how the aesthetic dimension of textiles may enhance principles of communal giving as an innovative strategy stretching beyond the coalition government’s Big Society agenda presented in 2010. Examples from investigations of textiles in museum archives including embroideries created by internees within Second World War prisoner-ofwar camps in the Far East are also examined. The aesthetic dimension of the embroideries carries significance through the vulnerable context in which they were created, as a potent series of statements involving cloth in action. In contemporary Britain, I have shown how such everyday objects as sleeping bags and travel tickets can capture the imagination by creating a connection with participants, when they may not have been consciously seeking an insight separate from the functionality of these objects. Nevertheless, an aesthetic gesture is surreptitiously tucked away. This has created a hybrid form of social engagement that can move fluidly between private and public spaces. The social engagement also involves processes of interaction and exchange with the object in the presentation of an active relationship with the object that is both seen and unseen.

Verstärkung der Wirkung von TTFields auf Glioblastomzellen durch Inhibition des mitotischen Spindelkontrollpunktes / Augmentation of the effects of TTFields on glioblastoma cells by mitotic checkpoint inhibitionFrömbling, Greta Eliza January 2020 (has links) (PDF)
TTFields sind eine Therapieoption des GBM, welche als alternierende elektrische Felder den Aufbau des mitotischen Spindelapparates stören. Gleichzeitig überwacht der SAC, mit seiner Schlüsselkomponente der Kinase MPS1, eine korrekte Anheftung der Spindelfasern an die Kinetochore der Chromosomen. Eine Inhibition des SAC durch den Inhibitor MPS1-IN-3 in Kombination mit Vincristin führt zu einem synergistischen Effekt auf das Tumorwachstum in vitro und in vivo. Aus diesen Erkenntnissen folgerten wir die Hypothese, dass eine SAC-Inhibition die Wirkung von TTFields verstärken könnte. Um dies zu testen, wurden Zellen der Zelllinien U87 und GaMG über 72h mit TTFields, MPS1-IN-3 oder einer Kombination aus den beiden behandelt. Anschließend wurden die Zellen gezählt, es wurde eine Analyse des Zellzyklus vorgenommen und apoptotische Zellen wurden via TUNEL-Assay detektiert. Die Kombinationsbehandlung aus TTFields und MPS1-IN-3 führte zu einer Reduktion der Zellzahl (U87: -54,3% vs. TTFields, p=0,0046; -52,9% vs. MPS1-IN-3, p=0,0026; GaMG: -74,3% vs. TTFields, p=0,0373; -84% vs. MPS1-IN-3, p<0,00001). Nur 28,1% mehr Zellen als ausgesät waren bei der Zelllinie U87 zu finden (TTFields: 179,1%; MPS1-IN-3: 168,3%), während es bei GaMG-Zellen sogar 62% weniger Zellen als ausgesät waren. Im Zellzyklus zeigte sich eine Abnahme der Zellen von der G1-Phase (U87: -59,9% vs. TTFields, p=0,0007; -42,1% vs. IN-3, p=0,0426; GaMG: -45,1% vs. TTFields, p=0,0276; -51,6% vs. IN-3, p=0,0020), während es zu einem massiven Anstieg von toten Zellen kam (U87: 2,9fach vs. TTFields, p=0,0022; 2,2fach vs. IN-3, p=0,0046; GaMG: 5,6fach vs. TTFields, p=0,0078; 7,8fach vs. IN-3, p=0,0005). Diese Zellen ließen sich im TUNEL-Assay als durch Apoptose zu Grunde gegangene Zellen weiter identifizieren (U87: 5,4fach vs. TTFields, p=0,0489; 6,2fach vs. IN-3, p=0,0278; GaMG: 8,9fach vs. IN-3, p=0,0110). Diese Ergebnisse sind erste und wichtige Hinweise für eine Verstärkung der Wirkung von TTFields durch eine Inhibition des SAC und liefern eine gute Grundlage für weitere Forschung zur Verbesserung der Therapie des GBM. / TTFields are -in addition to the standard therapy- approved for GBM therapy. TTFields are alternating electric fields at a low intensity, which cause disruption of the mitotic spindle fibers. Whether spindle fibers are properly attached to the kinetochores is surveilled by the SAC. An inhibition of the kinase MPS1, a key component of the SAC, in combination with Vincristine treatment, results in a synergistic effect on GBM growth in vitro an in vivo (Tannous, Kerami et al. 2013). We hypothesized that a combination of inhibition of SAC in combination with TTFields increases TTFields efficacy. Cells of the cell lines U87 and GaMG were treated either with TTFields alone, the inhibitor MPS1-IN-3 alone or in combination of both. After 72h cells were counted, an analysis of the cell cycle was performed and apoptotic cells were detected by using a TUNEL-Assay. The combined treatment of TTFields and inhibition of SAC led to a significant decrease of cells (U87: -54.3% vs. TTFields, p=0.0046; -52.9% vs. MPS1- IN-3, p=0.0026; GaMG: -74.3% vs. TTFields, p=0.0373; -84% vs. MPS1-IN-3, p<0.00001). U87 cells proliferated only by 28.1% compared to the cells seeded at the beginning, while cells of the GaMG cell line diminished by 62% compared to the number of cells seeded (TTFields: 179.1%; MPS1-IN-3: 168.3%). The cell cycle analysis showed -among other effects- a reduction of the cells in phase G1 (U87: - 59.9% vs. TTFields, p=0.0007; -42.1% vs. IN-3, p=0.0426; GaMG: -45.1% vs. TTFields, p=0.0276; -51.6% vs. IN-3, p=0.0020), and an increase of dead cells (U87: 2.9x vs. TTFields, p=0.0022; 2.2x vs. IN-3, p=0.0046; GaMG: 5.6x vs. TTFields, p=0.0078; 7.8x vs. IN-3, p=0.0005). Those dead cells were identified by the TUNEL- Assay as cells, which had undergone apoptosis (U87: 5.4x vs. TTFields, p=0.0489; 6.2x vs. IN-3, p=0.0278; GaMG: 8.9x vs. IN-3, p=0.0110). These results strengthen the hypothesis that TTFields’ efficacy is increased by a combined treatment with an inhibition of the SAC and provide a basis for further research to improve GBM therapy.

ÅTERANVÄNDBARA PARKERINGSHUS : En studie om att utveckla konceptet TempoDeckAl-sumasum, Rawia, Faías Ponce, Lara January 2016 (has links)
In today’s situation new methods are constantly evolving in the construction industry where the sustainability of a construction is of utmost importance. Prefabricated concrete is a type material that is highly durable in terms of long life without producing damaging effects. As a result, the material has been used increasingly in the manufacture of construction. Construction industry is continuously developing, which means new ways to construct buildings. Within construction, usage of prefabricated concrete is a method that has become increasingly successful. With this method, the construction period is shortened considerably and the construction process will be more beneficial for the environment and the various safety aspects. This master thesis was written in cooperation with AB Strängbetong, is one of the largest companies in Sweden that uses prefabricated elements. The company has a concept called TempoDeck and is currently building a parking garage in Ullared, with the life with a life expectancy of 50 years, that is life class L50. The objective of the study was to check whether the construction work fulfilled the requirements of the standards. In addition, the purpose was also to investigate the possibility of a different type of facade design by reducing the height of the joists and beams. The thesis includes a literature review, a case study, an archive analysis as well as calculations with the Norwegian program E – bjelke. A guidance from AB Strängbetong has also been used. The results showed that the existing structure fulfilled the life class L50 according to the requirements. In addition, the results showed that it was aesthetically possible to modify the car park, to make it more appealing. However, it would be more profitable to keep the design as it is to the future constructions. / I dagsläget utvecklas ständigt nya metoder inom byggbranschen där hållbarheten i en konstruktion är av ytterst stor vikt. Betong är ett material som är mycket hållbart då det har en väldigt lång livslängd utan att det ger större skadeverkan. Detta resulterar i att materialet brukas allt mer i tillverkning av byggnationer. Byggnadsteknik är i kontinuerlig utveckling vilket medför nya sätt att uppföra byggnader. Byggverksamhet går mer och mer åt att använda prefabricerade betongelement, en byggmetod som har blivit allt mer framgångsrik. Med denna metod kan byggtiden kortas ner väsentligt, byggprocessen blir även hälsosammare för omgivningen och är bättre ur olika arbetsmiljöaspekter. Detta examensarbete skrevs i samarbete med AB Strängbetong som är ett av de största företagen i Sverige som använder sig av prefabricerade element. Företaget har ett koncept vid namn TempoDeck och har byggt ett parkeringshus med en förväntad livslängd på 50 år, det vill säga livslängdsklassen L50. Uppdraget som gavs var att kontrollera om denna byggnation klarade av kraven enligt normerna. Syftet var även att kunna utveckla en annan typ av fasadutformning genom att minska höjden på bjälklaget och balkar. Avgränsningen inom studien är att den endast gjorts på ett företag, AB Strängbetong, och fokuseras bara på parkeringshus med hänsyn till betongens täckskiktskrav. Examensarbetet fullföljdes genom inläsning av litteratur, fallstudie såsom arkivanalys och beräkningar, med det norska programmet E-bjelke, samt handledning från AB Strängbetong. Resultaten visade att den befintliga konstruktionen klarade av livslängdsklassen L50 med hänsyn till kraven. Det fanns även möjligheter till att estetiskt sätt ändra på parkeringshusets utseende, för att få den mer tilltalande. Det skulle dock vara mer ekonomiskt lönsamt att behålla utformningen som konceptet har till de framtida byggnationerna.

CCSDS SPACE LINK EXTENSION (SLE) SERVICES -- OVERVIEW AND PROGRESS REPORTBrosi, Fred 10 1900 (has links)
International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / CCSDS Space Link Extension (SLE) Services enable the ground segment assets of space
agencies to interoperate, allowing for ground stations and space data users to interact without
the need for ad hoc, complicated gateways designed specifically for each new mission. Their
goal is to reduce the development, management, and operational costs of providing cross
support between space organizations for exchange of tracking, telemetry, and command
(TT&C) data. SLE services are actively supporting over a dozen spacecraft, with many more
planned over the next few years.
This paper first presents an overview of the underlying SLE architecture, as defined in the
SLE Reference Model. The SLE data transfer services, which move data between mission
facilities and ground stations are defined, along with the management services that enable
missions to make requests for ground station services. Next, up-to-date status of the testing,
prototyping, and implementation of SLE services over the past few years is presented, as well
as plans for adoption of SLE services by a number of space networks and space mission
organizations. Finally, efforts to adapt SLE services to support legacy missions are briefly
described.

CCSDS SPACE LINK EXTENSION SERVICE MANAGEMENT STANDARDS AND PROTOTYPING ACTIVITIESPietras, John 10 1900 (has links)
International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The Consultative Committee for Space Data Systems (CCSDS) is developing standards for the
interface through which spaceflight mission managers request tracking, telemetry, and command
(TT&C) and Space Link Extension (SLE) services from TT&C ground stations and networks. The
standards are intended for use not just by the spaceflight projects and networks operated by the
CCSDS member agencies, but also by commercial networks and networks operated by other
governmental agencies. As part of the process of developing the standards, several prototypes are
under development. This paper presents a summary status of both the emerging service request
standards and the prototypes that implement them.

ACHIEVING DATA TRANSFER AND SERVICE MANAGEMENT INTEROPERABILITY IN SATELLITE CONTROL NETWORKSSunshine, Carl, Williams, Lance 10 1900 (has links)
International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / A critical area for achieving interoperability between satellite control networks is the means chosen
to interconnect Satellite Operations Centers and remote antenna systems. The CCSDS Space Link
Extension (SLE) services are good candidates for this purpose, but national security space activities
have demanding requirements for accuracy of data transfer, controlled delay, and security, which
may not be fully achievable with the existing recommendations. The US Air Force developed a test
bed to evaluate the SLE protocols during live satellite contacts, for both data transfer and
management functions such as scheduling, configuring ground resources, and status reporting.
Performance was generally satisfactory, but several extensions were found to be necessary. The
SLE services provide a promising basis for use in ground stations to support both legacy Air Force
interfaces and newer standards based satellite control services.
