Objective. The volume of colonoscopies performed is increasing and differences in colonoscopy practice over time and between centres have been reported. Examination of current practice is important for benchmarking quality. The objective of this study was to examine variations in colonoscopy practice in endoscopy centres internationally. Material and methods. This observational study prospectively
Onshore wind turbines are becoming increasingly widespread globally, with the associated net effect that a greater number of people will be exposed to wind turbine noise (WTN). Sleep disturbance by WTN has been suggested to be of particular importance with regards to a potential impact on human health. Within the Wind Turbine Noise Effects on Sleep (WiTNES) project, we have experimentally investig
An amperometric immunoanalysis system based on monoclonal antibodies immobilized on Sepharose beads and packed into a micro-immunocolumn was developed for the quantification of microcystin-LR. Microcystin-LR (MCLR) was used as a reference microcystin variant. Inside the immunocolumn, free microcystins and microcystin-horseradish peroxidase (tracer) were sequentially captured by the immobilized ant
Ultrafast electronic and structural dynamics of matter govern rate and selectivity of chemical reactions, as well as phase transitions and efficient switching in functional materials. Since x-rays determine electronic and structural properties with elemental, chemical, orbital and magnetic selectivity, short pulse x-ray sources have become central enablers of ultrafast science. Despite of these st
Insects are fundamental to ecosystem functioning and biodiversity, yet the study of insect movement, dispersal and activity patterns remains a challenge. Here we present results from a novel high resolution laser-radar (lidar) system for quantifying flying insect abundance recorded during one summer night in Sweden. We compare lidar recordings with data from a light trap deployed alongside the lid
The convenience and the ease of use provided by hands-free operation of speech communication devices mean that speech enhancement schemes are becoming indispensable. In this chapter, two subband adaptive microphone array schemes are presented, which aim to provide good speech enhancement capability in poor signal to noise ratio situations. The basic commonality of the adaptive microphone array sch
This thesis examines some of the multiple variations of the previously established Rules of Thumb; which are used in attempting to explain implied volatility sur- faces. Here, these Rules are extensively tested on the Swedish stock market index (OMXS30) using rolling window analysis and linear stepwise regressions with for- ward selection. Data is collected on options at four different maturities
Concepts such as Creating Shared Value [CSV] and Strategic Corporate Social Responsibility [SCSR] respond to a demand for organisations to take responsibility for their contributions to increasing social issues such as social exclusion or the effects of climate change. The concept of SCSR is describing activities that provide economic values for organisations while at the same time targeting socia
För att nå ett fossilfritt och klimatneutralt Skåne krävs en omställning inom hela samhället, men hur kommer detta påverka energisystemet och vad ska vi prioritera för att minska klimatpåverkan i framtiden på ett effektivt sätt? Kan modelleringsverktyg som LEAP hjälpa till med att svara på dessa frågor? Resultatet pekar mot att transportsektorn kommer förbli den största energiförbrukaren i Skåne
This paper examines different authors and their reasons as to why they use pseudonyms. With the help of theories like Paratexts, Thresholds of Interpretation (1997) by Gérard Genette and Konvergenskulturen (2012) by Henry Jenkins, the essay provides an insight into why authors choose to use pseudonyms as well as publishers’ marketing strategies for this. To gain a better understanding of the world
Bröstcancer är idag en av de vanligaste cancerformerna hos svenska kvinnor; mer än 1400 avlider varje år till följd av sjukdomen. Ett sätt att reducera dödligheten är genom screeningprogram, där intent ionen är att detektera brösttumörer i ett tidigt stadie med hjälp av en röntgenundersökning som kallas mammografi. Alla kvinnor i åldra rna 40- 74 erb juds därför mammografi i förebyggande syfte, trAim: Virtual clinical trials (VCT) in medical imaging can be used to predict the outcome of clinical trials, by simulating anatomy, imaging methods and image interpretation. VCTs could reduce the cost and duration of clinical trials and their dependence on available patients. This thesis is motivated by the limitations in the field of breast cancer screening. The aim of the project is to expand a
This paper examines the relationship between female representation on corporate boards and financial performance in Swedish publicly listed companies from 2015 to 2023, excluding the year 2018. This study explores whether a higher proportion of women on boards of directors correlates with improved financial outcomes, measured by Tobin's Q. The empirical strategy employs both pooled Ordinary Le
Peroxisome proliferator-activated receptor gamma (PPAR-gamma) is a key regulator of metabolism, but how its structural dynamics control allosteric signaling remains unclear. To investigate this, we performed molecular dynamics simulations of PPAR-gamma and applied time-lagged independent component analysis to reduce the dimensionality of the data. Microstates were identified using K-means clusteri
Background: Perioperative myocardial injury (PMI) is associated with increased short-term major adverse cardio- and cerebrovascular events (MACCE) and mortality. We evaluated how different phenotypes of PMI based on timing of injury impact long-term MACCE and mortality among patients undergoing major noncardiac surgery (NCS). Methods: A prospective, observational study was carried out in 1290 pati
This thesis puts focus on Maria Aarts method "Marte meo" (on one's own strength). With the video camera as a principal tool, the purpose of the method is to be a practical working tool to support developmental processes on specific target groups, for example parents and their children. The aim of the thesis was to describe Swedish Marte meo Therapists and Marte meo Supervisors person
Background: Genital Chlamydia trachomatis (C.trachomatis) infection may lead to pregnancy complications such as miscarriage, preterm labour, low birthweight, preterm rupture of membranes, increased perinatal mortality, postpartum endometritis, chlamydial conjunctivitis and C.trachomatis pneumonia.This review supersedes a previous review on this topic. Objectives: To establish the most efficacious
Purpose: The purpose of this paper is to investigate the role of Google in everyday online searching activities of Swedish teenagers in different contexts. Design/methodology/approach: The study is qualitative and material has been produced through interviews and observations in two different schools with participants aged 15-16. Goffman’s frame analysis provides the analytical lens for studying h
Formation of Maillard products and the influencing factors, which are of crucial importance for both manufacturers and consumers, are still not fully understood. Thus in this study available lysine was used as a marker to monitor the extent of Maillard reactions in freeze-dried, spray-dried and drum-dried skim milk powders during 200 days of storage at highly controlled atmospheres. Storage variab
The building industry is facing a huge challenge as the industry sector carries much responsibility of the anthropogenic climate change: activities associated with housing alone account for as much as 30% of global annual energy demand. This demand derives not only from the physical characteristics of the buildings, but from the actions of the users, both end-users and professional managers. Even
The mechanical design of the EUROBALL neutron wall and neutron detectors, and their performance measured with a Cm-246,Cm-248 fission source are described. The array consists of 15 pseudohexaconical detector units subdivided into three, 149 mm high, hermetically separated segments and a smaller central pentagonal unit subdivided into five segments. The detectors are filled with Bicron BC501A liqui
