Popular Abstract in Swedish De fettlösliga vitaminerna upptäcktes i början av 1900 talet, och indelas i klasserna A, D, E och K. Brist på vitaminer i kroppen kan leda till svåra sjukdomar som nattblindhet, benskörhet och cancer. Även en överdos kan vara mycket allvarlig, och därför finns det bestämmelser om vilka livsmedel som ska vitaminberikas samt med hur mycket av varje vitamin. Dessutom utförSample clean-up methodologies based on supercritical fluid extraction (SFE) have been developed for determination of fat-soluble vitamins in foods. This thesis focuses on method development, stressing important issues concerning sample pre-treatment, extraction conditions and collection parameters. It was demonstrated that by using SFE followed by saponification and determination using RP-HPLC wit

Popular Abstract in Swedish I en alltmer konkurrenskraftig omvärld är det av störst vikt att i ett högkostnadsland som Sverige att innovera och utveckla produkter så effektivt som möjligt. För att uppnå dessa mål finns det klara indikationer på att våra nuvarande produktutvecklings- och konstruktionstillvägagångssätt saknar väsentliga egenskaper för att uppnå önskvärd effektivitet. Den frekvent mIn an industrial context when the product development cycles are shortened and constraints on technical innovations are high, it is very important to provide a very efficient and effective engineering design activity. In the current engineering design literature, most methodologies are by and large based on the so-called systematic engineering design approach. This approach is characterized by an

The only proven genetic risk factor for Chronic Obstructive Pulmonary Disease (COPD) is an inherited Z (Glu342¡úLys) deficiency of alpha-1-antitrypsin (AAT), a major inhibitor of neutrophil elastase. In vivo, AAT is found in both native (inhibitory) and modified (non-inhibitory) forms. There is now increasing evidence that the different forms of AAT may exhibit biological activities independent of

Popular Abstract in Swedish Kemiska ämnen finns överallt i vårat samhälle och behövs för att vi ska kunna leva som vi gör. Produktionen av kemiska ämnen använder kemiska processer som ofta är dyra och förbättringar av driftsätt kan spara mycket pengar. För att förbättra en process krävs att experiment utförs som oftast är väldigt kostsamma och tidskrävande. Ett sätt för att minska antalet experimeChemical processes are usually expensive to run. To optimise a process, we need to know how the process behaves, and this is usually accomplished by studying the process experimentally. However, experiments are very expensive, particularly if an existing plant has to shut down normal operation to conduct an experiment. A better way is to build a model and simulate the process. In order to obtain t

This dissertation investigates the labour migration from Southern Europe to Sweden, and the changes in Swedish immigration policy between 1960 and 1972. The overall ambition is to bring both the state and employers into the analysis of immigration policy and the recruitment of foreign labour - not separately but together in one study. The dissertation is divided into two main parts. The first part

The background of the project is partly found in a long tradition within library and information science (LIS) of meta-analyses on the field, partly in a science studies discussion on research fields and their contextual relation to wider academia, fields of professional practices and professionalization processes. The general purpose of the project is to analyze the social and intellectual develo

The emittances of the electron beams at the MAX-laboratory accelerator system have been studied. Apart from the build-up of the diagnostic tools for precise determination of the beam spatial profiles, the objectives have been: a) to verify the accelerator design emittances at low currents and to try to determine the emittances also at high currents; b) to investigate possibilities to manipulate th

We are currently witnessing a growing interest of network operators to migrate their ex- isting 2G/3G networks to 4G technologies such as long-term evolution (LTE) to enhance the user experience and service opportunities in terms of providing multi-megabit band- width, more efficient use of radio networks, latency reduction, and improved mobility. Along with this, there is a strong deployment of p

Proton-detected NMR diffusion and P-31 NMR chemical shifts/bandwidths measurements were used to investigate a series of liposomal formulations where size and PEGylation extent need to be controlled for ultrasound mediated drug release. The width of the P-31 line is sensitive to aggregate size and shape and self-diffusion H-1 NMR conveys information about diffusional motion, size, and PEGylation ex

BACKGROUND. Endometrial carcinomas seem to carry a different prognosis depending on the presence or absence of concomitant complex atypical hyperplasia (hyperplasia). The molecular genetic profile of these two pathogenetic types, based on the genes reportedly mutated in these cancers, remains to be defined. Although microsatellite inability is reported in approximately 25% of endometrial carcinoma

Direct and mediated electron transfer (DET and MET) between the enzyme and electrodes were compared for cellobiose dehydrogenase (CDH) from the basidiomycete Phanerochaete sordida (PsCDH). For DET, PsCDH was adsorbed at pyrolytic graphite (PG) electrodes while for MET the enzyme was covalently linked to a low potential Os redox polymer. Both types of electrodes were prepared in the presence of sin

The present thesis investigates, analyses and critically discusses the manner in which children with special needs are categorised in the Swedish preschool. The emergence of the category and its construction depends on a number of “truths” concerning children, related to historical and cultural processes in society. A main focus of the thesis is to investigate how legitimacy is established for the

Popular Abstract in Swedish Flertal studier talar för att såväl vaskulär demens som demens av Alzheimers typ är relaterade till blodtrycksnivå tidigare under livet. En studie har visat att redan blodtrycket vid 50- årsåldern är relaterat till kognitiva (intellektuella) funktioner vid 70-års ålder. En annan studie har visat att hypertoni i 70-årsåldern föregår utveckling av demens i ålder 80-85 år."Men born 1914" is a population based cohort study of the epidemiology of cardiovascular disease. Five hundred men, born 1914, were examined at the age of 68 and 185 of them were re-examined at 81 years of age. Examination included a medical and a psychological investigation, ultrasonographic measurement of carotid arteries, 24-hour ambulatory blood pressure monitoring, regional cerebral blood flo

Popular Abstract in Swedish Hårdvara och algoritmer för ett inbyggt videoövervakningssystem presenteras i denna avhandling. För att verifiera systemet så har en prototyp byggts.The demands on video surveillance systems are rapidly increasing regarding parameters such as frame rate and resolution. Furthermore, with an ever increasing number of video streams, an automated process for extracting relevant information is required. Due to the large amount of input data and the computational complexity of the algorithms, software implementations are not sufficient to sustain re

Popular Abstract in Swedish Cytostatika är en grupp läkemedel som är vanligt förekommande inom sjukvården. Cytostatika används framför allt vid behandling av olika cancersjukdomar, men kan också användas för att behandla andra sjukdomar t. ex. reumatiska sjukdomar. Dessa läkemedel kan vara mycket giftiga, cancerframkallande och fosterskadande. Cyklofosfamid (CP) och ifosfamid (IF) är två vanligt aAntineoplastic drugs are commonly used in the medical treatment of cancer and some other diseases. Workplaces e.g. hospital pharmacies and wards where antineoplastic drugs are used are contaminated with these drugs and health care workers are therefore at risk of getting occupationally exposed. Many antineoplastic drugs are classified as carcinogenic and teratogenic to humans. Cyclophosphamide (CP

To clarify the role of metabolic factors in endometrial carcinogenesis, we conducted a case-control study nested within the European Prospective Investigation into Cancer and Nutrition (EPIC), and examined the relation between prediagnostic plasma lipids, lipoproteins, and glucose, the metabolic syndrome (MetS; a cluster of metabolic factors) and endometrial cancer risk. Among pre- and postmenopau

Particle size distribution (size-range 3-900 nm) and PM10 was measured simultaneously at an urban background station in Copenhagen, a near-city background and a rural location during a period in September-November 2002. The study investigates the contribution from urban versus regional sources of particle number and mass concentration. The total particle number (ToN) and NOx are well correlated at
