The Homogenous Charge Compression Ignition (HCCI) combustion engine has potential to replace the spark ignition and compression ignition engines of today. One of the main problems in making the engine commercially attractive is the lack of direct means of controlling the ignition phasing. In this paper, we investigate the potential of inlet air temperature as a means to ignition actuation. This ar
BACKGROUND: Epithelial cells form the mucosal barriers that prevent the entry of mucosal pathogens, and respond to bacterial infections by producing various host defense molecules. In this study, we examined the inducible nitric oxide synthase (iNOS) response of primary human renal tubular epithelial cells (HRTEC) following infection with uropathogenic Escherichia coli Hu734, or stimulation with l
The noninvasive study of tissue blood volume and oxygenation using near-infrared light is a new and actively developing technology. We have used near-infrared spectroscopic imaging (NIRSI) to study hemodynamic responses on the auditory cortices evoked by auditory stimulation. Ten healthy newborn infants were studied. The otoacoustic emission hearing test was performed for each infant. Pulse oximet
Epitaxially-grown InAs nanowires may have great potential for nanowire device applications, due to the high electron mobility and narrow direct band gap of this material. Various applications will most likely require different selected growth conditions, due to such factors as temperature-sensitive substrates or pressure-dependent intrinsic doping. However, it has been reported that InAs nanowires
This study reassesses the occult philosophy of the British polymath John Dee (1527-1609). Focusing on his treatise Monas hieroglyphica (1564) and his notorious angelic conversations in the 1580s, it describes Dee’s philosophical career as a continuous search for a language which could yield knowledge of both nature and God. Situating Dee’s philosophy in the context of early modern “symbolic exeges
Abstract in Danish Denne afhandling handler om livskvalitet hos ældre mennesker med kræft. Risikoen for at få kræft stiger med alderen, og til trods for at de fleste mennesker, der får kræft er ældre, har forskning i hvordan ældre lever med en kræftsygdom været yderst begrænset. Viden om hvordan ældre mennesker oplever det at få en kræftdiagnose og hvordan de lever med sygdommen er en forudsætningOver the coming decades, the numbers of elderly will increase, and through improved lifestyles and better treatment longevity has increased, and with it, the risk of contracting cancer. How elderly people live with cancer has until now attracted limited research. The overall aim of this thesis was to investigate the QoL of elderly persons from the time of a cancer diagnosis through the following s
Since the basic concepts in the area of building physics are usually ignored, preventable failures are continuing to occur in modern buildings. The aim of this project is to evaluate the economic effects of different building physics aspects during the different stages in the building process and show the importance of applying building physics to designs. The hypothesis of this project is that ec
Interaction, communication and signification are fundamental to the human world. How do children use codes in their drawings, as in-struments of processing information, representing reality? I find use-ful tools in theories that focus upon the semiotic play, thought and language. The object of my study has been to analyze and describe children´s pictorial sign vehicle, in order to find the relatio
Study Design. The study is an observational cohort study. Objectives. To determine the incidence and the long-term outcome of thoracic or lumbar vertebral fractures in children. Summary of Background Data. The incidence of vertebral fractures in children is described as rare and the outcome as favorable. However, no studies evaluate the clinical and radiographic long-term outcome and if a fracture
The interaction between hydrogen peroxide and ozone has been studied in argon matrices using infrared spectroscopy. The spectra show that hydrogen peroxide forms a weak hydrogen bond to one of the end oxygens of ozone. A comparison is made with other ozone complexes.
Detailed information from the Swedish National Forest Inventory was used to simulate the carbon balance for Sweden by the process-based model Biome-BGC. A few shortcomings of the model were identified and solutions to those are proposed and also used in the simulations. The model was calibrated against CO2 flux data from 3 forests in central Sweden and then applied to the whole country divided int
Nonfatal heroin overdoses and suicide attempts are both common among heroin addicts, but there is limited knowledge about the association between them. The sample in the present study consisted of 149 regular heroin users in Malmo, Sweden. Out of these 98 had taken an unintentional heroin overdose at some time and 51 had made at least one attempt to commit suicide (but not using heroin). Suicide a
