This thesis describes analysis of data from the DELPHI Very Small Angle Tagger (VSAT) calorimeter at LEP1. The VSAT consists of four Silicon-Tungsten calorimeter modules symmetrically positioned 7.7 meters away from the interaction point. It measures elastically scattered electrons and positrons, Bhabha events, within the polar angular region between 5-12 mrad. Trigger efficiency and reconstructio
Signalling through gap junctions contributes to control insulin secretion and, thus, blood glucose levels. Gap junctions of the insulin-producing β-cells are made of connexin 36 (Cx36), which is encoded by the GJD2 gene. Cx36-null mice feature alterations mimicking those observed in type 2 diabetes (T2D). GJD2 is also expressed in neurons, which share a number of common features with pancreatic β-
Diabetes mellitus is one of the most common endocrine disorders in dogs and is commonly proposed to be of autoimmune origin. Although the clinical presentation of human type 1 diabetes (T1D) and canine diabetes are similar, the aetiologies may differ. The aim of this study was to investigate if autoimmune aetiology resembling human T1D is as prevalent in dogs as previously reported.
Background: Foods with a low glycemic index are increasingly being acknowledged as beneficial in relation to the insulin resistance syndrome. Certain organic acids can lower the glycemic index of bread products. However, the possible effect of acids in fermented milk products on the glycemic index and on insulinemic characteristics has not been addressed. The metabolic effects of fermented milk or
Popular Abstract in Swedish Avhandlingen innefattar 5 fristående artiklar samt en slutlig sammanfattning av samtliga arbeten. Arbetet behandlar textilproduktion under yngre järnålder framförallt vikingatid. Textilproduktionen har beaktats utifrån de textilredskap som påträffats vid utgrävningar av bosättningar i Skåne, Mälardalsområdet samt Birka, Sverige och Hedeby nuvarande Tyskland. Redskapen oThe initial aim of the present PhD thesis was to develop the method of classification for textile tools to facilitate the study of textile production in an archaeological context. The thesis consists of five separate projects and a concluding summary. The study covers the late Iron Age, mainly the Viking Period. Geographically, the study covers the regions of Scania, in S.W. Sweden, with seven set
The impacts of climate change are likely to exacerbate many problems that coastal areas already face. In this study, we used multinomial logistic regression to examine human perception of climate change based on a cross-sectional survey of 1253 individuals in coastal regions of Tanzania. This was complemented with time series analysis of 50-year meteorological data. The results indicate that self-
Aim. The aim of this study was to compare preoperative patient evaluation by a vascular physician with a standardized workup protocol prior to elective endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA), in terms of differences in patient medication and mortality. Methods. Consecutive patients with infrarenal AAA treated with standard EVAR from 1998 to 2006 (group 2) and 2007
Background: Birthweight and gestational age are key indicators for perinatal health obtained through the birth certificate. Knowing the validity of birth certificate data is crucial when identifying needs and evaluating birth outcomes. In Spain, vital information is reported by parents and is not checked for consistency with any hospital document. Therefore, to perform a validation study and descr
Abstract in UndeterminedThis work presents a comparative study regarding wear behavior between a novel abrasion resistant cast iron, "Carbide Steel" and a number of conventional tool materials frequently used in the automotive industry. Carbide Steel is basically a high-Cr white cast iron heavily alloyed with cemented carbide. The high chromium content and additional alloying elements like WC. TiC
Purpose: Transitional cell carcinoma (TCC) of the prostate/prostatic urethra is a risk factor for urethral recurrence after radical cystoprostatectomy for TCC. Using conventional sectioning techniques, prostate involvement (prostatic urethra, acini, ducts and/ or stroma) has been detected in a range of 10-20% of the patients, whereas transversal whole mount sectioning has revealed 43% prostate inv
Popular Abstract in Swedish "Det var en gång en kung som aldrig gjorde något bra för sina undersåtar. Han gjorde faktiskt aldrig nånting. Det enda han ville var att äta och dricka, och berusa sig tillsammans med sitt hov. Under tiden svalt folket ihjäl." Anna frågar: varför kunde inte människorna äta hemma? "Tyst nu, och lyssna på fortsättningen…" (citat ur avhandlingen) Martina Camparts forskniAbstract The point of departure for this study is the author's experience as educator in a residential home for children (age 6-14) with social-emotional problems, in Italy, between 1980 and 1989. One important element of the pedagogical approach was the use of narratives (personal, of others, of fiction) to prompt children's interest/ motivation to reflect about issues of personal concern. A conv
Background: Oral contraceptive use has been associated with an increase in the risk of breast cancer in young women. We examined whether this association is seen in women at high risk of breast cancer because they carry a mutation in one of two breast cancer susceptibility genes, BRCA1 and BRCA2. Methods: We performed a matched case-control study on 1311 pairs of women with known deleterious BRCA1
The work presented deals with the characterisation and application of critical gels. In order to provide a theoretical foundation, the thermodynamics of the reversible swelling and shrinking behaviour of such gels is outlined. The temperature-sensitive poly(N-isopropylacrylamide) gel (NiPAAm) was chosen for experimental investigation. Dif ferent methods of producing the gel are described, and the
This chapter highlights user perspectives related to the development of ICT and the launching of political strategies to involve users in the IT society. Strategies are discussed in relation to cooperation between technical and social scientists. The author points to the fact that the diffrences between various theoretical understandings of the interaction between technology and social change tend
The heat shock proteins (HSPs) HSP70 and gp96 from necrotic tumour cells are considered to function as chaperones in presenting tumour antigens. We therefore studied HSP70 and immune cells in a transplantable carcinoma in the liver of rats after interstitial laser thermotherapy (ILT). Experiments were performed in Wistar FU rats using a dimethyl-hydrazine-induced adenocarcinoma implanted into the
Radiative lifetimes have been measured for two excited levels of Ce IV using the time-resolved laser-induced fluorescence technique. Ce3+ ions were produced in a laser-induced plasma. In the measurements, a suitable magnetic field was applied to reduce the recombination between electrons and the ions and thus the background light from the recombination, and special care was exercised to avoid flig
In this article career as metaphor and various career models are the object of a critical review. The question at issue is whether career as metaphor helps us understand the social dynamics that characterize substance abuse? Different career models such as the stepping-stone and gateway hypothesis and H S Beckers career model is scrutinized. It is pointed out that these career models are one-sided
