This paper presents the outcomes of an applied cultural study carried out during spring semester 2010 with more than 10 Chinese female postgraduate students in Swedish universities. The aims of this research were to investigate Chinese female postgraduates’ decision-making process, to understand university lives in Sweden with the main focus on their learning experiences and social activities, and
Decentralization has in recent decades become a common concept in public policy making especially in developing countries. The concept, defined here as the transfer of functions, responsibilities and financial resources to lower levels of government, is further expected to have a positive effect on a country´s development process by reducing the inefficiency associated with a centralized form of g
Two of Cassian’s works, the Institutiones and the Collationes, are preserved in both Latin and Greek, and almost all scholars have taken it for granted that he wrote exclusively in Latin. This paper examines two passages from Cassian’s writings, one from the Institutiones (which has a parallel in an Evagrian florilegium) and the other from the Collationes. Arguing against the prevailing view, the
Urgent structural change is required in higher education, to allow collaboration both within and across universities, so that achieving rapid sustainability transition can become not only the overarching but the main purpose of education, research and work in society. A review of the literature reveals that fragmentation caused by traditional hierarchical faculty and disciplinary organisation is a
Förintelsen är en historisk händelse som lever vidare i samtidens medvetande i form av minnesmonument och museala minnesutställningar och processas av forskningsinstitutioner och myndigheter. Bland överlevandefamiljerna lever minnet kvar och nu har några av deras barnbarn, den Tredje generationens överlevande, tagit på sig att förvalta minnet. Samtidigt florerar antisemitismen i det svensk samhällThe Holocaust is an event that lives on in societies’ consciousness in the form of memorial monuments and museums, and is processed by research institutions and authorities. My own journey began when meeting upper secondary students who denied the Holocaust, and I soon came in contact with a group who identify themselves as Third Generation Survivors; grandchildren of those who survived the Holoca
Optimization and electrical control of photovoltaic (PV) and proton exchange membrane (PEM) electrolyzer systems are critical for efficient, scalable hydrogen production. Static coupling methods employ fixed electrical interconnections between PV arrays and the PEM stack, which cannot adapt to fluctuating irradiance or temperature. To overcome this, we propose an adaptive reconfiguration optimizat
Both high-mountain rivers and wet-based mountain glaciers are considered effective erosion agents. They acted alternatively or simultaneously during the late Quaternary in the Tatra Mountains (West Carpathians) thus producing a vast amount of clastic material that was subject to deposition, reworking and transportation downstream. A small fraction of that amount of the material is still preserved
Single-molecule spectroscopy techniques are used to investigate time fluctuations of the fluorescence properties of two different types of conjugated polymer, a polythiophene derivative (PDOPT) and a phenylene vinylene derivative (MEH-PPV), at 100 and 293 K. Linear correlation coefficients between fluorescence intensity and polarization are used to characterize fluctuations. We are able to disting
Popular Abstract in Swedish I avhandlingen presenteras delar till radiomottagare med extremt låg effektförbrukning. Detta behövs då dagens samhälle blir allt mer och mer uppkopplat, och detta gäller inte bara persondatorer och mobiltelefoner. Med den snabba teknikutvecklingen inom radiokommunikation, driven av små och smarta mobiltelefoner, går det nu även att få prylar av alla de slag att tala meHistorically, research on radio communication has focused on improving range and data rate. In the last decade, however, there has been an increasing demand for low power and low cost radios that can provide connectivity with small devices around us. They should be able to offer basic connectivity with a power consumption low enough to function extended periods of time on a single battery charge,
When ferrochromium is produced at Vargon Alloys AB (Vargon, Sweden), an offgas dust is generated as a byproduct. A leachate that contains hexavalent chromium (Cr6+) is formed when rainwater percolates through the dust deposit. In this study, Cr6+ in the leachate was reduced to trivalent chromium (Cr3+) by biological treatment in a biofilm process operated under anaerobic conditions. The reactor vo
Carotenoids are one of the most widespread and important group of pigments in Nature and they can act as light-harvesting agents, photoprotectors and antioxidants. Mechanisms of their multiple functions are not fully understood mainly because their complicated photophysics involving ?dark? excited states. The central theme of this thesis is characterization of the lowest dark S1 state of carotenoi
Partially Premixed Combustion (PPC) is an advanced combustion concept resulting in high efficiencies and low emission levels by the use of high levels of EGR and pilot injections. The main limitation of PPC to use in practice lies in the high pressure rise rate, which causes issues on engine noise and durability. In addition, soot emissions face with the overshoot problem during the transient oper
Partially Premixed Combustion (PPC) is a promising advanced combustion mode for future engines. In order to investigate the sensitivity of PPC to exhaust gas recirculation (EGR) rate, intake gas temperature, intake gas pressure, and injection timing, these parameters were swept individually at three different loads in a single cylinder diesel engine with gasoline-like fuel.A factor of sensitivity
It is a public health priority to identify the adverse and non-adverse associations between pharmaceutical medications and cancer. We search for and evaluate associations between all prescribed medications and longitudinal cancer risk in participants of the Swedish Cancer Register (N = 9,014,975). We associated 552 different medications with incident cancer risk (any, breast, colon, and prostate)
Ever since the invention of the internal combustion engine, there has been an interest in optimizing the in-cylinder pressure to achieve reliable and efficient work output. With the use of in-cylinder pressure sensors, piezoelectric injector actuation, the possibility of multiple injection events and the increased availability of computation power, cycle-to-cycle, in-cylinder pressure optimization
Modelica allows systems to be described with reuseable components and with a high precision. To be able to use such complex models efficiently, high demands are set on tools that allow the user to extract the information needed from the models in a straight-forward manner. For this purpose, design-of-experiments techniques can be used to systematically analyze the complex models.In this paper, it
This study compares the time required to activate a grasp or function of a hand prosthesis when using an electromyogram (EMG) based control scheme and when using a control scheme combining EMG and control signals from an inductive tongue control system (ITCS). Using a cross-over study design, 10 able-bodied subjects used a computer model of a hand and completed simulated grasping exercises. The ti
