High voltage long pulse klystron modulators typically use pulse transformers, where the length of the pulse dictates the size of the transformer. Recent advancements in power electronics applied to modulator technology, in order to facilitate multi-millisecond long pulse generation, instead suggests use of high frequency transformers in a high frequency pulse modulation/demodulation scheme, elimin

Purpose: To model prediction of undetected glaucoma in a predominantly white population, based on intraocular pressure (IOP) and subject age. Methods: In 1992–1997, a population screening for glaucoma was performed at Malmö University Hospital where individuals between 55–79 years of age (n = 46 614) living in Malmö, were invited to a free eye health examination. Recently examined patients were no

Context: Type 2 diabetes mellitus (T2DM) is accompanied by an increased risk for coronary artery disease (CAD), but the overlapping metabolic disturbances preceding both diseases are insufficiently described. Objective:Wehypothesized that alterations in metabolism occur years before clinical manifestation of T2DM and CAD and that these alterations are reflected in the plasma metabolome. We thus ai

Purpose: To describe which types of assistive devices prescribed and actually used, either due to precautions or due to true functional reasons, after hip fracture-related hemiarthroplasty. Materials and methods: About 394 patients cluster-randomized 2010–2014 at a university hospital. Control group with standard postoperative precautions to reduce dislocations, mandatory assistive devices and kne

The human host has evolved elaborate protection mechanisms to prevent infection from the billions of microorganisms to which it host is exposed and is home. One of these systems, complement, is an evolutionary ancient arm of innate immunity essential for combatting bacterial infection. Complement permits the efficient labelling of bacteria with opsonins, supports phagocytosis, and facilitates phag

Klimatförändringarna kommer att påverka ekosystem och samhällen över hela världen. Det är ett problem som kräver drastiska och omedelbara förändringar av vårt sätt att leva och av våra samhällsstrukturer, och därmed politiskt engagemang av aldrig tidigare skådat slag. Under de senaste 30 åren, sedan bildandet av Förenta Nationernas ramkonvention om klimatförändringar (Klimatkonventionen; UNFCCC) åThe rise of climate change as an issue of global concern has rested on scientific representation and understanding of the causes and impacts of, and responses to climatic change. The Intergovernmental Panel on Climate Change (IPCC), in particular, has been central to how climate change has become known as a global political problem. This thesis aims to critically examine the production, negotiatio

Lack of recovery from everyday strains and demands is connected to increased levels of stress-related problems and development of ill-health. There is much research on how to handle and prevent fatigue and stress in leisure time, but research on working time is more scarce. A recent study found that employees' experience of recovery during working hours was related to high self-rated health. OBJEC

Background: Video capsule endoscopy (VCE) is a noninvasive method enabling excellent visualization of the small bowel (SB) mucosa. The aim of this study was to examine the impact and safety of VCE performed in children and adolescents with suspected or established Crohn’s disease (CD). Methods: A total of 180 VCE examinations in 169 consecutive patients conducted in 2003–14 in a single center were

Background: Previous reports on effect of antioxidants on sperm DNA integrity were equivocal, and there is a lack of randomized, placebo-controlled studies. Objectives: To evaluate the efficacy of combined antioxidant treatment in subfertile men with normal reproductive hormone levels and high sperm DNA fragmentation index (DFI). Materials and methods: This placebo-controlled, double-blind, random

Problem: Emergency care in child and adolescent psychiatry often lacks a coherent treatment model. This study reports on the development and implementation of a salutogenic treatment model at the Child & Adolescent Psychiatric Emergency Unit in Malmö, Sweden. Methods: The development and implementation involved all staff categories and was guided by a recognized authority on salutogenesis. Gen

This research engages with the space beyond cinema and comprises a futuristic vision about the condition of cinema.My work takes a conceptual approach that considers cinema in an architectural sense and as an instrument, where the environment, the screen, and the projection can be combined or pushed forward to create another spatiotemporal dimension that is concurrent with and beyond the context o

Freshwater scarcity is an ever-increasing problem throughout the arid and semi-arid countries, and it often results in poverty. Thus, it is necessary to enhance understanding of freshwater resources availability, particularly for groundwater, and to be able to implement functional water resources plans. This study introduces a novel statistical approach combined with a data-mining ensemble model,

BACKGROUND: Throughout the world, the scarcity of donor organs makes optimal allocation systems necessary. In the Scandiatransplant countries, organs for lung transplantation are allocated nationally. To ensure shorter wait time for critically ill patients, the Scandiatransplant urgent lung allocation system (ScULAS) was introduced in 2009, giving supranational priority to patients considered urge
