Experiments on a modern DI Diesel engine were carried out: The engine was fuelled with standard Diesel fuel, RME and a mixture of 85% standard Diesel fuel, 5% RME and 10% higher alcohols under low load conditions (4 bar IMEP). During these experiments, different external EGR levels were applied while the injection timing was chosen in a way to keep the location of 50% heat release constant. Emissi
The development of real-time ultrasound in the 1970's made indelible inpact on antenatal care. Assessing foetal growth and detecting deviations from normal in both growth and foetal anatomy became fesible. Expectant parents could also 'see' their foetus. Normal foetal growth parameters at term were consituted and selected parameters from the second trimester were evaluated in the detection of chro

A nonionic lamellar phase was prepared using C10E3 in buffer solution at pH = 7.6. A suitable T4DNA concentration around 5 wt % was immobilized in a lamellar phase with 40 wt % C10E3. The mixed system was investigated at two temperatures, 25 and 5 degrees C by using cryo-fracture TEM direct imaging, fluorescence microscopy and small-angle X-ray scattering. The surprising results where obtained sho
Background: Up to half the residents of nursing homes for the elderly have asymptomatic bacteriuria (ABU), which should not be treated with antibiotics. A complementary test to discriminate between symptomatic urinary tract infections (UTI) and ABU is needed, as diagnostic uncertainty is likely to generate significant antibiotic overtreatment. Previous studies indicate that Interleukin-6 (IL-6) in
Aktuell status för dagvattenhantering i grannstäderna Köpenhamn och Malmö studerades med avseende på befintliga åtgärder och genomförda systemen i de båda städerna. Tillämpning av blå-gröna lösningar i de yttre delarna av Malmö började på 1990-talet och följaktligen är samarbete mellan olika avdelningar inom kommunen mer strukturerat i Malmö medan processen i Köpenhamn fortfarande är baserad på trThe current status of storm-water management in the neighbor cities of Copenhagen and Malmö was studied with respect to present measures and the implemented systems in both cities. Application of blue-green solutions in the outer parts of Malmö started in the 1990s; hence collaboration between different departments in the municipality is more structured in the city of Malmö while in Copenhagen the
Popular Abstract in Swedish En industrirobot är en flexibel programmerbar maskin som bör användas för sådant arbete som inte lämpar sig för människan att utföra. Olika tekniska begränsningar i dagens styrsystem begränsar dock robotars tillämpbarhet. Avhandlingen föreslår ett nytt sätt att bygga upp robotstyrsystem så att roboten på bästa sätt skall kunna tjäna människan.Industrial robots play a key role in manufacturing systems. Robots are distinguished from other types of machinery mainly on the basis of their programmability and ability to be adaptable to different tasks. The use of computer control to achieve desired flexibility implies that software issues for embedded control systems are central for the applicability and utilization of the equipment. The str
Different aspects of hybrid control systems are treated: analysis, simulation, design and implementation. A systematic methodology using extended Lyapunov theory for design of hybrid systems is developed. The methodology is based on conventional control designs in separate regions together with a switching strategy. Dynamics are not well defined if the control design methods lead to fast mode sw
Dissemination of risk information is ubiquitous in contemporary society. We explore how individuals react in everyday life to health-risk information, based on what they report in personal interviews. Health-risk information was without exception recognized as unstable and inconsistent. This conformity, however, did not extend to the narratives regarding how health-risk information should be handl
Popular Abstract in Swedish Varje år besöker ungefär 100 000 människor från hela världen klostret i den lilla franska byn Taizé. De flesta är ungdomar. Och 4000 av dem är svenskar. Här stannar de en vecka och deltar i brödernas intensiva andaktsliv tre gånger dagligen. Andakterna kännetecknas av meditativ tystnad och korta repetitiva mantra-lika sånger. Vad händer med en människas religiösa attityA considerably small amount of empirical research was found on the process of religious facilitation through liturgical participation and worship (cf., Heimbrock & Boudewijnse, 1990; Wikström, 1994a, 1994b). Using a quasi-experimental design, the present investigation therefore addressed this issue. The process of religious facilitation through intense liturgical participation was regarded as
B-cell lymphoma (BCL) heterogeneity represents a key issue, often making the classification and clinical management of these patients challenging. In this pilot study, we outlined the first resolved view of BCL disease heterogeneity on the protein level by deciphering disease-associated plasma biomarkers, specific for chronic lymphocytic leukemia, diffuse large B-cell lymphoma, follicular lymphoma
Visceral leishmaniasis (VL) is a potentially fatal vector-borne zoonotic disease, which has become an increasing public health problem in the north-western part of Iran. This work presents an environmental health modelling approach to map the potential of VL outbreaks in this part of the country. Radial basis functional link networks is used as a data-driven method for predictive mapping of VL in
The Wilms tumor gene, WT1, encodes a zinc-finger DNA binding protein which is thought to function as a tissue specific transcription factor, regulating cell growth and differentiation. High expression of WT1 has been detected in a range of acute leukemias. To elucidate a role for WT1 in leukemogenesis, we transfected the monoblastic cell line U937, which lacks detectable levels of endogenous WT1,
Event-based control is a promising concept for the design of resource-efficient feedback systems, where events such as sampling, actuation, and data transmissions are triggered reactively based on monitored control performance rather than a periodic timer. In this thesis, we investigate how sampling and communication events should be triggered to fully exploit the potential of event-based control
Desludging is considered a key step in urban sanitation improvement. Nevertheless, in most urban unplanned settlements, desludging is performed in an unhygienic manner, risking public health. This study used a combination of qualitative and quantitative methods to analyse the underlying factors for unhygienic desludging in three urban unplanned settlements of Dar es Salaam, Tanzania. Factors for u
The development of social media challenges the established conceptualizations of resources in social movements. While previous theories largely illustrated social movements as constantly searching for new and more resources, the development of social media has allowed some actors to gather and mobilize extensive resources rapidly, calling for an analysis of resource abundance. The aim of this arti
Taking as its starting point the scholarly discussion about the possible death of the Aesopic fable towards the end of the eighteenth century, this article proposes a broadening of perspective, arguing for a thorough examination of the impact of modernity on some of the basic contexts and conditions of the genre. Four contextual factors are, subsequently, placed under scrutiny: the ethics of virtu
Aim: The Cockcroft-Gault (CG) creatinine-based equation is still used to estimate glomerular filtration rate (eGFR) for drug dosage adjustment. Incorrect eGFR may lead to hazardous over- or underdosing. Methods: In a cross-sectional analysis, CG was validated against measured GFR (mGFR) in 14 804 participants and compared with the Modification-of-Diet-in-Renal-Diseases (MDRD), Chronic-Kidney-Disea
