The detection of spectral line profile variability for stars of the HgMnclass of chemical peculiarity has been poorly documented in theliterature yet holds a special significance for understandingrelationships between observed spectral anomalies, stellar surfacestructure, and magnetic fields. The HgMn stars have until now not beenconfirmed to vary in their light or spectral characteristics in ways
Popular Abstract in Swedish Det blir allt vanligare att man ersätter förlorade och skadade kroppsdelar med ett biomaterial (vanligtvis ett metall eller polymer implantat). Exempel på vanliga användningsområden är; suturer, kärl, hjärtklaffar, pacemakers, katetrar, ledproteser, fixationsskruvar för skelett och konstgjorda tänder samt kapslar för långsam frisättning av medicin. Trots det rutinmässigThe biological response to different implanted biomaterials vary. The relative importance of factors in the material and host for this variation are at present incompletely known. The variation in the cellular response to specific proteins and the rapid adsorption of proteins to surfaces exposed to biological environments has created the hypothesis that the cellular interactions with biomaterials
Popular Abstract in Swedish Liksom du och jag, måste växter andas för att kunna leva. Med hjälp av luftens syre förbränns näring i form av bl a kolhydrater och fetter till koldioxid. Den energi som avges vid förbränningen omvandlas till ATP, som är cellens bränsle. Den huvudsakliga produktionen av ATP sker i den del av cellen som kallas mitokondrien, cellens kraftverk. Vän av ordning kliar sig nu In addition to proton-pumping complex I, the plant respiratory chain contains type II NAD(P)H dehydrogenases. These extra enzymes do not pump protons and consequently do not contribute to the electrochemical proton gradient. Database screening of the Arabidopsis genome identified seven type II NAD(P)H dehydrogenase homologues of which two and four genes were closely related to potato (Solanum tube
Popular Abstract in Swedish Genteknik innebär stora möjligheter att förändra och förbättra organismers egenskaper. Genom att i en organism föra in en främmande gen kan man ge den helt nya egenskaper som den aldrig skulle ha förvärvat på naturlig väg. Genmodifierade bakterier odlas idag industriellt i stora bioreaktorer för tillverkning av olika proteiner, till exempel insulin till diabetiker, humaVitreoscilla is an obligate aerobic bacterium living in oxygen-poor environments such as stagnant ponds and decaying vegetable matter. Vitreoscilla expresses a homodimeric haemoglobin (VHb) when subjected to oxygen-limited conditions. In several organisms, expression of VHb has been shown to increase microaerobic cell growth and enhance oxygen-dependent cell metabolism. Moreover, the presence of V
The Second String Quartet by Arnold Schoenberg, written in 1907 and 1908, is breaking musical traditions at least twice – (1) by leaving tonality, (2) by breaking the genre of string quartet, adding a voice who is interpreting two poems by the German symbolist Stefan George in its third and forth movements. In this paper, I want to raise the question about the reasons why Schoenberg might have add
This thesis describes novel molecular host-parasite interactions with potential significance for the understanding of pathological processes manifested with bacterial infections. Bacterial surface proteins and virulence determinants are shown to mediate the accumulation at the surface of the pathogen of key components of the fibrinolytic and contact phase systems. Plasmin(ogen) binding surface pr
Major databases on western clothing and their thermal properties are available, but information on non-western clothing is lacking. A recent ASHRAE project 1504 TRP, Extension of the Clothing Insulation Database for Standard 55 and ISO 7730 dealt with the issue. Simultaneously, a co-operation study at Indian workplaces allowed us to acquire some sets of the traditional clothes used at construction
The Proletarian Pedagogy of the Pioneers: Education Through Self-Cultivation, Immersion, and Creativity with the Aim to Achieve the Communist Utopia, 1924–1929. The thesis examines how the Swedish pioneer movement between the years 1924 and 1929 tried to raise the new socialist generation through a pedagogy which they believed were necessary to achieve the Communist Utopia, the classless society.
Intracellulära CD59 proteinerna IRIS-1 och IRIS-2 i hjärnan Tidigare har två nya varianter av CD59 proteinet vid namn ”Isoforms Rescuing Insulin Secretion 1/2” (IRIS-1/2) upptäckts i betaceller inuti bukspottskörteln som bland annat är kroppens insulinfabrik, där de visat sig reglera exporten av insulin ut i blodet. Detta sker via ett protein komplex som kallas SNARE komplexet. Dessa proteiner foRecently, two intracellular isoforms of CD59 were discovered in pancreatic beta cells. They proved crucial for insulin secretion and were named Isoforms Rescuing Insulin Secretion 1 and 2 (IRIS-1 and IRIS-2), whose expression decreased in type 2 diabetes (T2D). IRIS-1 and 2 were found across many different tissues on the mRNA level, including the brain. This Master's Thesis focuses on the role
There is a strong need to replace animal-based experiments with in vitro alternatives. Mutz-3, a myeloid cell line, has been successfully used to investigate skin sensitization. A problem with in vitro assays, not only affecting Mutz-3, is the use of Fetal Bovine Serum for cell cultivation, as it is a serum supplement which is not fully defined, and it introduces variability in cell-based experime
Hur kan naturliga dagvattensystem förhindra översvämningar i våra städer? Kraftigare skyfall och fler hårdgjorda ytor ökar risken för översvämningar i städer. I detta arbete utvecklades en metod för att undersöka bästa möjliga placering av blågröna lösningar för att avlasta vattenledningarna i området. Denna metod tillämpades senare på ett område i Lund där olika lösningar simulerades och effektiClimate change and increasing urbanization pose significant challenges to our urban environment. Urbanization leads to more impermeable surfaces, which, in combination with more rainfall, put communities at risk of flooding due to combined sewer overflows or overloaded drainage systems. To combat urban flooding, natural systems, also called blue-green solutions, can be implemented to mimic the nat
Black carbon (BC), a major component of fine particulate matter (PM2.5), has been implicated in adverse neurodevelopmental outcomes, including autism spectrum disorders (ASD). While PM2.5 has been associated with increased ASD risk, the specific role of BC remains uncertain. This study aimed to assess prenatal exposure to BC and risk for ASD development in a low exposure setting, using a large, hi
BACKGROUND AND OBJECTIVES: Tau accumulation pattern shows substantial variability in Alzheimer disease (AD), and 4 distinct spatiotemporal trajectories were distinguished using a data-driven approach called the Subtype and Stage Inference (SuStaIn). A visual method to validate and identify these subtypes is a requirement for their clinical translation. Our study aimed to provide a standardized top
INTRODUCTION: We sought to harmonize genotype data from the predementia AMYPAD (Amyloid Imaging to Prevent Alzheimer's Disease) Consortium, compute polygenic risk scores (PRS), and determine their association with global amyloid deposition. METHODS: Genetic data from five AMYPAD parent cohorts were harmonized, and PRS were computed for Alzheimer's disease (AD) susceptibility, cerebrospinal fluid (
Our main purpose with this study is to examine and elucidate the recovery process that occurs when women choose to break up from destructive relationships. Our aim is also to clarify what, by the women themselves, is considered to be efficient help in relation to what in fact is offered in actuality. The idea of this selection was that we, in the study of the recovery process, would make a compili
This study deals with the development of a subglacial cavity in a province dominated by stoss- and leeside rockridges. In the area of Järnavik, south-central Blekinge, there is a small excavation on the leeside of a bedrock ridge. The lithofacies combinations in this section contains both diamictons and sorted sediments. The diamict units are both massive and stratified. The sorted sediments are m
The evaluation of clinical radiographs with the European Image Criteria method has in previous work proven to be an easy and straightforward method. The main drawback with this method is the large inter-observer variation. It has been proposed that the reason for this is that the observers get “distracted” by the surrounding structures in the image and that a sort of “first impression” of the imag
Payments for ecosystem services (PES), a mechanism of incentives or compensation to landowners for provision of ecosystem services, have grown as a tool for meeting conservation goals. The Costa Rican payments for ecosystem services (PSA) program is one of the best-known examples because of being one of the most established. Despite this, the PSA program and many other PES programs do not monitor
Background With obesity levels on the rise globally, it is necessary to create a healthier food environment and increase access to nourishing and palatable foods. Dietary fibre consumption has been proven to be one of the best ways to prevent cardiovascular diseases and type 2 diabetes. Glucanova AB developed an oat bran and barley-based product and investigated the daylong effect on glucose respo
A lot of time and care have been put into exploring and explaining the power relations between nurses and nursing assistants, the emotional investment appropriate in care work, different views on leisure time for staff in this context (Warming, 2019; Habel, 2021; Jervis, 2002; Crocker, 2019). Less work has been done in exploring the complex relationships care workers have with their patients and h
