Optimization of sensory processing during development can be studied by using photoreceptors of hemimetabolous insects (with incomplete metamorphosis) as a research model. We have addressed this topic in the stick insect Carausius morosus, where retinal growth after hatching is accompanied by a diurnal-to-nocturnal shift in behavior, by recording from photoreceptors of first instar nymphs and adul
This article is an analysis of the Swedish feature film "Brita i grosshandlarhuset" from 1946 about a poor girl that moves to the city finding employment as a maid in the house of a rich merchant. Here I examine the compromises - in terms of constructions of class and gender - that paved the way for a new narrative, with the progression of imagery from, so to speak, the symbol of the merchant hous
Objectives: Little is known about the biological processes causing aortic aneurysm rupture. Chronic Chlomydophila pneumoniae infection has been suggested as a possible contributing factor to the development and expansion of abdominal aortic aneurysm (AAA). The importance of infection in AAA may be related to the previous pathogen burden, that is, the number of significant titres of antibodies agai
We report on the use of binary mixtures of oppositely charged gold nanoparticles (AuNPs) and spherical polyelectrolyte brushes (SPBs), consisting of a polystyrene core onto which long polystyrene sulfonate chains are grafted, as a simple model system to investigate the influence of directional interactions on self-assembly. We demonstrate that the mixing ratio, i.e., the number of AuNPs per SPB, h
In this work we present the first XOS degrading glycoside hydrolase from Weissella, WXyn43, a two-domain enzyme from GH43. The gene was amplified from genomic DNA of the XOS utilizing Weissella strain 92, classified under the species pair Weissella cibaria/W.confusa, and expressed in Escherichia coli. The enzyme is lacking a putative signal peptide and is, from a homology model, shown to be compos
Popular Abstract in Swedish Under livets gång utsätts vi för en mängd exponeringar som påverkar vår hälsa. I denna avhandling har vi försökt förstå hur olika exponeringar påverkar risken för celiaki (glutenintolerans) hos barn. Vi har utnyttjat information i nationella register och använt epidemiologiska metoder. Med ett socialepidemiologiskt tankesätt lyfter vi blicken från individen till att äveCeliac disease is a chronic gastrointestinal disease affecting approximately 1% of the population. It is precipitated in genetically predisposed individuals by ingestion of food containing gluten or similar proteins that are present in wheat, rye and barley. The disease might present with symtoms such as malnutrition, diarrhea or abdominal bloating, but a large proportion of those afflicted by the
The aims of this work were to evaluate objective and subjective signs of autonomic dysfunction (AD) in patients with primary Sjögren’s syndrome (pSS) and to evaluate its clinical associations. In study I, 46 pSS patients and 56/80/238 autonomic nervous function test (ANT) controls participated. Objective signs of AD were evaluated using three different cardiovascular ANTs and exocrine function in
This article addresses the understanding of Islam of nine young adult Muslims living in the Malmo and Copenhagen region. 1 Throughout the interviews with the young adults, they mark their distance from what they perceive as unacceptable forms of Islamic ideas and practices, labeling these ideas as extremist and inconsistent. They develop discursive techniques of distancing themselves from the medi
For the first time, we report experimentally and theoretically that nitroaromatic compounds, 2,4-dinitrobenzenethiol and 4-chloro-2-nitrobenzenethiol, on silver sols can be selectively reduced to 2-amino-4-nitrobenzenethiol and 2-amino-4-chlorobenzenethiol simply by irradiating with a visible light in ambient conditions, and the selective photoreduction is a very facile process. The results of qua
There is still controversy as to how body mass index (BMI) affects male reproduction. We investigated how BMI is associated with semen quality and reproductive hormones in 166 men, including 38 severely obese men. Standard semen analysis and sperm DNA integrity analysis were performed, and blood samples were analysed for reproductive hormones. Adjusted for age and time of abstinence, BMI was negat
Popular Abstract in SwedishI avhandlingen undersöks adoptionsberättelser i en svensk kontext. Syftet är tvåfaldigt: För det första, hur adoption beskrivs av vuxna adopterade, för det andra, hur adoption konstrueras i dagspress. Adopterades sätt att skapa mening kring att ”vara adopterad” är i fokus, så är även dessa personliga berättelsers samspel med kulturellt gångbara diskurser på adoptionsområThis dissertation explores adoption stories in a Swedish context. The aim is two-fold: First, how adoption is presented by adopted adults; second, how adoption is constructed in the press. The way adoptees create meaning of “being adopted” is investigated; the way those stories are shaped culturally is also explored. The study was conducted in a qualitative tradition with a constructionist and nar
Near-haploid chromosome numbers have been found in less than 1% of cytogenetically reported tumors, but seem to be more common in certain neoplasms including the malignant cartilage-producing tumor chondrosarcoma. By a literature survey of published karyotypes from chondrosarcomas we could confirm that loss of chromosomes resulting in hyperhaploid-hypodiploid cells is common and that these cells m
Objective To investigate the genetic control of chronic arthritis and collagen epitope specific antibody responses in an experimental model for rheumatoid arthritis. Methods The chronic collagen induced arthritis (CCIA) model was used, induced with collagen type II (CII) in mineral oil lacking mycobacterium in BALB/c (n=24), B10.Q (n=44), (BALB/c x B10.Q) F1 (n=85) and B10.Q x (BALB/c x B10.Q) N2
The results of a search for the production of second generation scalar leptoquarks are presented for final states consisting of either two muons and at least two jets or a muon plus missing transverse momentum and at least two jets. A total of 1.03 fb(-1) integrated luminosity of proton-proton collision data produced by the Large Hadron Collider at root s = 7 TeV and recorded by the ATLAS detector

Changes in the Swedish construction code introduced in 1994 enabled the construction of wooden multi-storey buildings. The main issue in those is disturbing vibrations and noise propagating throughout the construction. Therefore, gaining knowledge about their behavior is of crucial importance for the industry. In this study, a mockup of a wall/floor junction was investigated by comparing both expe
