Increasing heat will be a significant problem for Central European cities in the future. Shading devices are discussed as a method to mitigate heat stress on citizens. To analyze the physical processes, which are characteristic of shading in terms of urban human-biometeorology, experimental investigations on the thermal effects of shading by a building and shading by tree canopies were conducted i
Gonyostmum semen is a freshwater raphidophyte that has increased in occurrence and abundance in several countries in northern Europe since the 1980s. More recently, the species has expanded rapidly also in north-eastern Europe, and it is frequently referred to as invasive. To better understand the species history, we have explored the phylogeography of G. semen using strains from northern Europe,
Human embryonic stem cells offer a potential unlimited supply for functional hepatocytes, since they can differentiate into hepatocyte-like cells displaying a characteristic hepatic morphology and expressing various hepatic markers. These cells could be used in various applications such as studies of drug metabolism and hepatotoxicity, which however, would require a significant expression of drug
This study investigates the association between Ronald Inglehart's materialist/postmaterialist index, a psychological aspect of the material pathway to inequalities in health, and health locus of control and psychological health. The data used is from the 2008 public health survey in Skane, a cross-sectional postal questionnaire study with 28,198 respondents (response rate 54%), conducted in south
he present study investigated the unique contribution of learning approaches to academic performance, also taking gender differences into account. The participant sample consisted of 476 school pupils (53% girls and 47% boys) from two upper secondary schools in Sweden who completed two self-reported measures related to personality and learning approaches and one cognitive ability test. A series of
Genomic aberrations of key regulators of the apoptotic pathway have hardly been identified in neuroblastoma. We detected high BCL2 mRNA and protein levels in the majority of neuroblastoma tumours by Affymetrix expression profiling and Tissue Micro Array analysis. This BCL2 mRNA expression is strongly elevated compared to normal tissues and other malignancies. Most neuroblastoma cell lines lack thi
Purpose: The primary aim was to analyse regional incidences of retinopathy of prematurity (ROP) and frequencies of treatment and their relation to perinatal risk factors during a 3-year period. A secondary aim was to study adherence to the study screening protocol in the different regions. Methods: A population-based study of neonatal morbidity in extremely preterm infants in Sweden (EXPRESS) was
Objectives: Circulating microRNAs (miRNAs) are promising as biomarkers for various diseases. We examined the release patterns of cardiospecific miRNAs in a closed-chest, large animal ischemia-reperfusion model and in patients with ST elevation myocardial infarction (STEMI). Methods: Six anesthetized pigs were subjected to coronary occlusion-reperfusion. Plasma, urine, and clinical parameters were
Popular Abstract in Swedish Tjocktarmcancer är en av de vanligaste cancerformerna i västvärlden. I Sverige drabbas årligen ca 5000 människor. Ungefär 10% av fallen går att härleda till ärftliga faktorer medan den övervägande delen orsakas av miljöfaktorer. Kända riskfaktorer är fysisk inaktivitet, fetma och rökning. Risken för cancer påverkas dock mest av den kost vi äter. Allmänt kan sägas att enSphingomyelin (SM) is present both in eucaryotic cells and the diet. Sphingomyelinase (SMase) hydrolyses SM and generates ceramide that has been implicated in the regulation of cell growth, differentiation and apoptosis. Previously a SMase with alkaline pH optimum was identified in the intestinal tract. The thesis studied the distribution pattern, the species difference and the clinical implicatio
"The Glittering Misery" has treated certain aspects of Swedish society during the decades around the turn of the 19th Century. The enlisted men of the Crown Prince´s Hussar Regiment in Malmö have been utilised as a means by which to analyse society at this point in time. Questions which have been answered are: who the hussars were and what sort of life did they lead? What form did the relationship
Issues with software product quality are commonly reported when organisations engage in outsourcing relationships. To address this issue, value-based software engineering literature emphasises the need for all success-critical stakeholder groups to work towards a mutually agreed goal. Aim: This paper presents a case study that aims to compare and contrast the priority two groups place on software
High resolution transmission electron microscopy and digital image processing has been used to investigate the structure and properties of inorganic materials. The image processing was performed with the programming language Semper. All routines are listed in the appendix. The local order in the disordered mineral blatterite was investigated, and was found to extend over several unit cells. The
Popular Abstract in Swedish Magsårsbakterien H. pylori binder till och förändrar magens slemhinna Bakterierna är i majoritet i kroppen! Människans 10 biljoner celler lever i harmoni med 100 biljoner bakterier som har koloniserat någon av kroppens ekologiska nischer utan att göra skada. Av alla bakterier kroppen möter utgör bara en bråkdel något hot, och trots att kroppen möter sjukdomsalstrande bHelicobacter pylori may cause gastritis, gastric/duodenal ulcer and gastric cancer. During infection, most H. pylori are found in the gastric mucus layer, but some are attached to, or have penetrated, epithelial cells. The aim of this study is to characterize the binding of H. pylori to gastric mucins and to investigate host changes that occur after inoculation. Results: H. pylori binds to mucins
In 1995 and 1996 a Swedish feed mill had problems due to a persistent contamination of Salmonella enterica spp. enterica serovar Senftenberg that was difficult to eliminate. Forty-eight strains isolated from the feed mill, together with unrelated strains included to evaluate the discriminatory power and reproducibility, were analysed by pulsed-field gel electrophoresis (PFGE). The source of contam
It has been stated many times that the formation of radiation infringements in PbWO4 is to a big extent stipulated by the non-stoichiometry defects of the crystals, arising in the process of their growth and annealing. To refine the idea of characteristics of the non-stoichiometry defects and their effect on the radiation hardness of PbWO4, the current study is aimed at the melt composition infrin
The fate of ornithine in the nephron of the female OF-1 Swiss mouse remains unknown. The aim of the present study was to identify the nephron segments containing the key enzymes involved in ornithine metabolism: ornithine decarboxylase (ODC) and ornithine aminotransferase (OAT). Viable tubules isolated by microdissection were incubated with [1-14C]ornithine to study the oxidative pathway. Other tu
This dissertation argues that the English Protestant interpretations between 1845 and 1864 of John Henry Newman’s secession were related to the notions which formed part of the British national identity. It demonstrates how various writers modelled their interpretations of Newman’s secession on the beliefs of British anti-Catholicism. By understanding the British national identity as a common cult
In this study a set of structures has been simulated to represent a range of clinically relevant breast cancer mammographic lesions including solid tumours and microcalcifications. All structures have been created using simple random-based mathematical functions and have been inserted into a subset of digital mammography images at appropriate contrast levels into various regions of the breast, inc
