We have studied the pH effect on the S0 and S2 multiline electron paramagnetic resonance (EPR) signals from the water-oxidizing complex of photosystem II. Around pH 6, the maximum signal intensities were detected. On both the acidic and alkaline sides of pH 6, the intensities of the EPR signals decreased. Two pKs were determined for the S0 multiline signal; pK1 = 4.2 ± 0.2 and pK2 = 8.0 ± 0.1, and
In this chapter, a control design approach based on linear parametervarying (LPV) systems, which can be exploited to solve several problems typically encountered in control engineering, is presented. By means of recent techniques based on Youla–Kucera parametrization, it is shown how it is possible not only to design and optimize stabilizing controllers, but also to exploit the structure of the Yo
The general objective of this thesis was to increase the knowledge of how mental health and school performance are associated and how interventions may be designed and implemented to enhance the two.The data used in the four quantitative studies on which this thesis is based were derived from two age cohorts of students attending 14 elementary schools in two cities in the southern part of Sweden.
Background: Concerns have been raised about increased gambling problems during the coronavirus disease (COVID-19) crisis, particularly in settings with high online gambling and risks of migration from land-based to riskier online-based gambling types. However, few non-self-reported data sources are hitherto available. The present study aimed to assess changes in the online- and land-based gambling
We discuss the results of Gibson and Sailor (Boundary-Layer Meteorol 145:399–406, 2012)who suggest several corrections to themathematical formulation of the Lagrangianparticle dispersion model of Rotach et al. (Q J R Meteorol Soc 122:367–389, 1996). Whilemost of the suggested corrections had already been implemented in the 1990s, one suggestedcorrection raises a valid point, but results in a viola
A search for new phenomena in final states containing an e+e- or μ+μ- pair, jets, and large missing transverse momentum is presented. This analysis makes use of proton–proton collision data with an integrated luminosity of 36.1fb-1, collected during 2015 and 2016 at a centre-of-mass energy s=13TeV with the ATLAS detector at the Large Hadron Collider. The search targets the pair production of super
OBJECTIVE: To assess the reliability of knee extensor and flexor muscle strength measurements in persons with late effects of polio. DESIGN: A test-retest reliability study. SUBJECTS: Thirty men and women (mean age 63 (standard deviation 6.4) years) with verified late effects of polio. METHODS: Knee extensor and flexor muscle strength in both lower limbs were measured twice 7 days apart using a Bi
Purpose: To evaluate the association between a previously published 313 variant–based breast cancer (BC) polygenic risk score (PRS313) and contralateral breast cancer (CBC) risk, in BRCA1 and BRCA2 pathogenic variant heterozygotes. Methods: We included women of European ancestry with a prevalent first primary invasive BC (BRCA1 = 6,591 with 1,402 prevalent CBC cases; BRCA2 = 4,208 with 647 prevale
Background and Objectives: Blood services manage the increasingly tight balance between the supply and demand of blood products, and their role in health research is expanding. This review explores the themes that may define the future of blood banking. Materials and Methods: We reviewed the PubMed database for articles on emerging/new blood-derived products and the utilization of blood donors in
PURPOSE: The purpose of this study was to examine the psychometric properties of the Swedish short form of the Speech, Spatial and Qualities of Hearing Scale (SSQ12) and investigate whether the paper-and-pen and online formats could be used interchangeably. METHOD: Individuals with and without hearing problems were invited to participate in this study. The participants (N = 125) were randomized in
Multi-archive studies of climate events and archive-specific response times require synchronous time scales. Aligning common variations in the cosmogenic radionuclide production rate via curve fitting methods provides a tool for the continuous synchronization of natural environmental archives down to decadal precision. Based on this approach, we synchronize 10Be records from Western Gotland Basin
Mental health issues differ widely among individuals, with varied signs and symptoms. Recently, language-based assessments have shown promise in capturing this diversity, but they require a substantial sample of words per person for accuracy. This work introduces the task of Adaptive Language-Based Assessment (ALBA), which involves adaptively ordering questions while also scoring an individual’s l
Road safety policy rules us in both visible and invisible ways and prioritising one mode often means downgrading another. It has been argued in previous research that road safety policy prioritises car traffic and in that way sustains the automobility norm. This paper focuses on the automobility norm that permeates Swedish road safety policy and how this hampers planning for cycling. It aims to co
PurposeEpithelial ovarian cancer is usually diagnosed in the advanced stages. To choose the best therapeutic approach, an accurate preoperative assessment of the tumour extent is crucial. This study aimed to determine whether the peritoneal cancer index (PCI), the amount of ascites, and the presence of cardiophrenic nodes (CPLNs) visualized by computed tomography (CT) can assess the tumour extent
Background: Cleft lip with cleft palate (CLP) is a congenital condition that affects both the oral cavity and the lips. This study estimated the prevalence and mortality of CLP using surveillance data collected from birth defect registries around the world. Methods: Data from 22 population- and hospital-based surveillance programs affiliated with the International Clearinghouse for Birth Defects S
