The thesis explores the implications of digital ethnic media for International diaspora through an empirical analysis of virtual Chinese diaspora spaces. The analysis shows that the Chinese cultural sphere is a heterogeneous and pluralistic space which is diverse, segmented but connected. The multicultural sphere fosters the complexity of interactions within digital ethnic community, by means of t
Denna rapport redogör för design och utveckling av ett medicintekniskt instrument för diagnos av kronisk obstruktiv lungsjukdom (KOL) eller emfysem. Arbetet utgår ifrån en ny diagnosmetod och ett instrument i form av en funktionell prototyp som används för att testa den nya diagnosmetoden. Med utgångspunkt i den funktionella prototypen har arbetet fokuserats kring att förstå vilka problem och utmThis thesis presents design and development of a medical device for diagnosis of emphysema or COPD by controlled lung deposition of nanoparticles. After purging the lungs with particle free air the subject inhales a controlled aerosol mixture and holds his breath for a determined period of time, before exhaling. The degree of lung disease is calculated by measuring and comparing the concentration
This master thesis is about improving the accuracy of a Gantry-Tau robot by identifying the key parameters in the kinematics of the robot. This is done using a vision system and then estimating the parameters by minimizing the closure equation of the kinematics. The robot with improved control is then used for additive manufacturing. Furthermore, a prototype for a large plastic printer head is pre
The production, transport, and deposition of mineral dust exert major influences on climate change and Earth’s biogeochemical cycles. Furthermore, their imprint, as recorded in pelagic sediments, provides an avenue for determining past changes in terrestrial aridity and atmospheric circulation patterns in response to global climate change. Here, by examining geochemical and magnetic data obtained
Language is a complex semiotic system based on the context-sensitive use of signs, in contrast to the comparatively rigid systems of signals used by other animals, making it a uniquely human bio-cultural adaptation. But equally unique for human beings are other semiotic systems, and their corresponding sociocultural practices, such as (representational) gesture, the use of pictures and music. Cruc
Background: Recent studies indicate the need to examine how the gut microbiota–brain axis is implicated in pain, sensory reactivity and gastro-intestinal symptoms in autism spectrum disorder (ASD), but no scale exists that assesses all these constructs simultaneously. Methods: We created a pool of 100 items based on the real-world experience of autistic people, and a multidisciplinary team and sta
There are extensive data on the toxicity of glyphosate (GLY) based herbicides (GBH), however the interpretation of some data (e.g. carcinogenic effect) are subject to controversy. For the appropriate health risk assessment more data on exposure levels in the general population, especially in susceptible groups such as pregnant women, the elderly and children are needed. The aims of the present stu
Cows produce saliva in very large quantities to lubricate and facilitate food processing. Estimates indicate an amount of 50–150 L per day. Human saliva has previously been found to contain numerous antibacterial components, such as lysozyme, histatins, members of the S-100 family and lactoferrin, to limit pathogen colonization. Cows depend on a complex microbial community in their digestive syste
This work presents a systematic study of the properties (Light Output Non-Uniformity (LONU) and energy resolution) of two CsI(Tl) scintillation units over a span of almost three years, under adverse conditions of humidity and temperature. These two crystals are part of the CALIFA detector, a highly segmented calorimeter and spectrometer for γ rays and light-charged particles, that is placed surrou
Tuning of protein surface charge is a fundamental mechanism in biological systems. Protein charge is regulated in a physiological context by pH and interaction with counterions. We report on charge inversion and the related reentrant condensation in solutions of globular proteins with different multivalent metal cations. In particular, we focus on the changes in phase behavior and charge regulatio
Background: Erysipelas is a common infection that often reoccurs, but only a few studies have investigated risk factors for recurrent episodes. How the natural course of events in the infection corresponds to the inflammatory signs is not well described. Objective: The aim of this study was to indentify risk factors for recurrent erysipelas and the possibility to study the course of events
In the last decade, Hong Kong maintains a relatively stable and sustained economic growth compared to other developed countries despite the Asian Financial Crisis in 1997, the outburst of IT Bubble in 2001, the Severe Acute Respiratory Syndrome in 2003. This thesis suggests that integration with China is the reason for such growth. Many studies have shown that Hong Kong and China have been closely
En proglacial miljö är en integrerad del av ett glacialt landskap, där smältvattensavlagrade landformer är vanligt förekommande. Deras utseende är beroende av ett antal olika faktorer, så som processer aktiva under transport och deposition samt ursprungsmaterialets karaktär. Denna artikel syftar till att undersöka två terrestra smältvattens-successioner från de terminala delarna av glaciären MyrdaProglacial environments are an integrated part of the glacier landscape, housing a variety of landforms fed by glacier meltwater. Their appearance is dependent on a number of factors, such as the variability of source material and processes active during the transportation and deposition. The present work aims to investigate two such terrestrial outwash successions from the terminus region of the
Aim: The aim of this degree project is to carry out the corporate wide analysis and investigation to identify the existing and upcoming sustainable practices in Thule AB, general awareness and perception on sustainability among employees and to calculate carbon footprint of a bike rack, a Thule product produced at Seymour plant, USA. Approach: We embarked on this project by dividing it into two di
