Understanding how and why some groups have become more species-rich than others, and how past biogeography may have shaped their current distribution, are questions that evolutionary biologists have long attempted to answer. We investigated diversification patterns and historical biogeography of a hyperdiverse lineage of Lepidoptera, the geometrid moths, by studying its most species-rich tribe Boa
The taxonomic position and evolution of the five Scandinavian montane species previously referred to the informal group Depilata of Hieracium are discussed. There is very little modern information about these species and as they have not been listed under any of the currently accepted sections of the genus they are at risk of being completely forgotten. They have always been considered as intermed
The long-term psychological effects resulting from carrier testing and prenatal diagnosis (PD) of haemophilia were evaluated by comparing mental symptomatology scores (Symptom Check List, SCL-90) for 50 carriers of haemophilia who had undergone PD about five years earlier, 55 carriers who had not undergone PD and 262 control women who were not carriers. All of the women had children. Carrier testi
AIMS: Despite exclusion of left atrial thrombi by transoesophageal echocardiography, cardioversion-related thromboembolism has been reported in atrial fibrillation or flutter. To define a low-risk group for cardioversion without previous anticoagulation, patients were selected for immediate cardioversion if there were no thrombi, no echo spontaneous contrast and the outflow velocity of the left at
UNLABELLED: The aim of this systemic review and meta-analysis was to examine the differences in caesarean section rates across European regions and at a country level by utilizing the Robson classification system. The study has compared caesarean rates across European regions using the Robson classification to identify the drivers of caesarean section use. This review shows significant variations
Streptolysin O (SLO) is a cholesterol-dependent cytolysin produced by the important human pathogen, group A Streptococcus (Streptococcus pyogenes or GAS). In addition to its cytolytic activity, SLO mediates the translocation of GAS NAD-glycohydrolase (NADase) into human epithelial cells in vitro. Production of both NADase and SLO is associated with augmented host cell injury beyond that produced b
Adolescence can be a stressful period in life. The period contains challenges associated with the transition from childhood to adulthood (body changes, changes in interpersonal relationships, and identity changes). The aim was to investigate experiences of stress among adolescents in addition to stress related to the COVID-19 pandemic. Focus group interviews (n = 8) were conducted with girls (n =
Due to the steadily growing world chainsaw market and the market’s relative competitiveness, high performing chainsaws are important for Husqvarna Group AB to remain competitive. In the development phase a large number of endurance tests are run to evaluate the product’s performance. Given the data gathered from these tests, the main goal of this thesis was to model the time until failure and eval

Access to water is a necessity for farmers for them to be able to produce food. This poses a problem in Jordan, one of the world’s driest countries, but also in Sweden, where after a drought in the summer of 2018 the state of the water levels was more critical than ever. Virtual reality (VR) has shown to be a tool with a good effect on students’ learning. In this work VR has been taken advantage o
This research tests two different focus groups with the purpose of developing quantitative online surveys suitable for a specific target group. Depending on where in the development process of the survey the researcher is, somewhat different focus groups should be used. If the researcher is far into the development of the survey a focus group with the questionnaire template as discussion basis cou
Objective: The aim of this study was to explore healthcare workers' opinions on workplace related health resources relevant to promotion of their health. Participants: 16 registered nurses and 19 assistant nurses, from a medical emergency ward at a medium sized hospital in the south of Sweden, participated in the study. Methods: Eight focus group interviews were conducted, the material was con
Abstract in Spanish Antecedentes: Las pruebas cutáneas con determinantes mayores y menores de la penicilina se utilizan de forma habitual para el diagnóstico de reacciones de hipersensibilidad inmediata a los antibióticos betalactámicos. Estos extractos diagnósticos han sido recientemente retirados del mercado europeo. Objetivo: Estudio de una nueva marca de determinantes para el diagnóstico de reBACKGROUND: Skin testing with major and minor determinants of benzylpenicillin is recommended standard practice for the evaluation of patients with immediate hypersensitivity reactions to beta-lactams. However, commercial reagents for this purpose were recently dropped from the European market. OBJECTIVE: In the present study, we assessed a new brand of reagents for use in skin testing in patients
