Designing a Novel Prototype for Efficient Blood Sampling and Storage: An Experimental Study on Plasma Separation CardsLundgren, Philip, Ghebreyesus, Adam January 2024 (has links)
The aim of this study is to optimize the storage and shipping processes of Plasma Separation Cards (PSC) by developing a novel prototype designed to reduce manual labore and ensure sample integrity. An experimental design was employed to address current limitations in PSC handling. These limitations include labor-intensive processes and potential sample degradation. In this approach rigorous testing was done to evaluate the prototype's performance in various environments and different materials. The research in this study include lab testing of samples stored in the prototype, assessment of different storage conditions and analysis of shipping processes. The main research question was: “How can a prototype for PSC storage be optimized to reduce manual labor in PSC handling while ensuring sample integrity during storage and shipping?”. To answer this question the prototype was tested for its effectiveness in reducing storage space and facilitating automated handling The findings of this study show that the prototype that was created can significantly reduce the required storage space while still being usable by liquid handling robots. During the study it was noted that minor misalignment issues were present due to the limitations of the type of 3D printers used. These issues could be addressed with more precise printing technologies such as Stereolithography (SLA) or Selective Laser Sintering (SLS). Both materials used in this study, PLA (Polylactic acid) and PETG (Polyethylene Terephthalate Glycol) materials were found suitable for storing PSC samples under most conditions. However, the measurements for the samples with PLA indicated limitations at 65 °C under certain conditions, making PETG a safer choice under higher temperature. The study contributes to the field by providing an innovating solution for PSC sampling that is scalable. This enhances the possibility for remote monitoring end predictive diagnostics. The prototype indicates a promising direction for future research and application and medical diagnostics by improving operational efficiency while aligning with sustainability goals. This study explores the following aspects: sample handling, storage and shipping. The practical implication includes reduced manual labor, minimized human error and increased efficiency for these aspects.

"Ich dichte in die wüste Zeit" - Ich-Konstruktionen in der Lyrik der deutschsprachiger Schriftsteller_innen Israels / "I am writing into deserted times" - Constructions of the I in the German poetry of the Israeli writers Netti Boleslav and Jenny AloniPoppe, Judith 27 August 2015 (has links)
Die vorliegende Arbeit untersucht eine in der bisherigen Literaturgeschichtsschreibung unbeachtete Literatur – die deutschsprachige Literatur Israels. Exemplarisch wird dafür die Lyrik zweier Autor_innen, Jenny Aloni und Netti Boleslav, in den Blick genommen.
Jenny Aloni und Netti Boleslav emigrierten Ende der 1930er Jahre aus dem nationalsozialistischen Deutschland bzw. Prag nach Israel, fanden dort eine neue Heimat und verfassten bis zu ihrem Tod in den 1980er bzw. 1990er Jahren in deutscher Sprache Lyrik und Prosa. Leben und Werk der Autor_innen werden in der Arbeit auf der Basis von Dokumenten wie Tagebüchern, Briefen und unveröffentlichten Manuskripten rekonstruiert, die hier zum Teil erstmals aus dem Nachlass gezogen und in die literarische Öffentlichkeit eingebracht werden.
Die hermeneutische Untersuchung der Gedichte in ihrem poetischen Eigenwert wird durch die Einbeziehung poststrukturalistisch-kulturwissenschaftlicher Methoden ergänzt. Die Studie rückt die Ich-Konstruktionen in den Fokus – sowohl die der empirische Autor_innen als auch die der literarischen Ichs – und verfolgt damit die Fäden an unterschiedliche Zeiten und Orte zurück, in und an denen die Literatur ihre Spuren hinterlassen hat. Auf der Basis der Analysen wird die untersuchte Literatur, basierend auf Konzepten von Deleuze/Guattari und Kühne, schließlich als „Kleine Zwischenliteratur“ bezeichnet.
Die Literatur Alonis und Boleslavs erscheint in Spannungsfeldern zwischen deutschem und israelischem Literaturbetrieb, mäandert zwischen Einheiten wie Böhmen, dem nationalsozialistischen und postnationalsozialistischen Deutschland, dem Staat Israel, der CSSR aber auch zwischen „jüdischer“ und „israelischer“ Literatur, deutscher Popkultur, Naturlyrik und zionistischer Geschichtsschreibung. Die Literaturgeschichte hat diese einmalige Positionierung der deutschsprachigen Literatur bisher nahezu unbeachtet gelassen. Mit der vorliegenden Arbeit wird dieser blinde Fleck geschlossen.
Um dieser Literatur ihr Zuhause zu geben, so die abschließende Forderung der Arbeit, sind transdisziplinär und transnational Überlegungen anzustellen, wie die Literaturwissenschaft den Schnittmengen zwischen diesen zwei Literaturgeschichten institutionell und konzeptionell gerecht werden kann.

Spatial technology as a tool to analyse and combat crimeEloff, Corné 30 November 2006 (has links)
This study explores the utilisation of spatial technologies as a tool to analyse and combat crime. The study deals specifically with remote sensing and its potential for being integrated with geographical information systems (GIS). The integrated spatial approach resulted in the understanding of land use class behaviour over time and its relationship to specific crime incidents per police precinct area.
The incorporation of spatial technologies to test criminological theories in practice, such as the ecological theories of criminology, provides the science with strategic value. It proves the value of combining multi-disciplinary scientific fields to create a more advanced platform to understand land use behaviour and its relationship to crime.
Crime in South Africa is a serious concern and it impacts negatively on so many lives. The fear of crime, the loss of life, the socio-economic impact of crime, etc. create the impression that the battle against crime has been lost. The limited knowledge base within the law enforcement agencies, limited logistical resources and low retention rate of critical staff all contribute to making the reduction of crime more difficult to achieve.
A practical procedure of using remote sensing technology integrated with geographical information systems (GIS), overlaid with geo-coded crime data to provide a spatial technological basis to analyse and combat crime, is illustrated by a practical study of the Tshwane municipality area. The methodology applied in this study required multi-skilled resources incorporating GIS and the understanding of crime to integrate the diverse scientific fields into a consolidated process that can contribute to the combating of crime in general.
The existence of informal settlement areas in South Africa stresses the socio-economic problems that need to be addressed as there is a clear correlation of land use data with serious crime incidents in these areas. The fact that no formal cadastre exists for these areas, combined with a great diversity in densification and growth of the periphery, makes analysis very difficult without remote sensing imagery. Revisits over time to assess changes in these areas in order to adapt policing strategies will create an improved information layer for responding to crime. Final computerised maps generated from remote sensing and GIS layers are not the only information that can be used to prevent and combat crime. An important recipe for ultimately successfully managing and controlling crime in South Africa is to strategically combine training of the law enforcement agencies in the use of spatial information with police science.
The researcher concludes with the hope that this study will contribute to the improved utilisation of spatial technology to analyse and combat crime in South Africa. The ultimate vision is the expansion of the science of criminology by adding an advanced spatial technology module to its curriculum. / Criminology / D.Litt. et Phil. (Criminology)
