Background: The adoption of air conditioning (AC) is growing rapidly in developing countries across the world which puts a high burden on electricity distribution systems. This development is mostly driven by income growth and building design, but also due to increasing outdoor temperatures and to provide indoor thermal comfort. Current indoor thermal comfort standards are based on western clothin
Environmental factors are thought to play a major role in the development of rheumatoid arthritis. Because the use of ethanol is widespread, we assessed the role of ethanol intake on the propensity to develop chronic arthritis. Collagen type II-immunized mice were given water or water containing 10% (vol/vol) ethanol or its metabolite acetaldehyde. Their development of arthritis was assessed, as w
Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant disorder in humans that is characterised by multisystemic vascular dyplasia and recurrent haemorrhage. Germline mutations in one of two different genes, endoglin or ALK1 can cause HHT. Both are members of the transforming growth factor (TGF) beta receptor family of proteins, and are expressed primarily on the surface of endothel
The infrared spectrum of water, isolated in inert matrices, has been studied in the interval from 60 to 4000 cm(-1). Experiments with partially deuterated water combined with DFT (density functional theory) calculations have been used to investigate the structure of matrix-isolated water tetramer. A few, strong intermolecular fundamentals of the water tetramer have been observed. Mid-infrared band
Purpose - The dimple is adopted into a pin fin wedge duct which is widely used in modern gas turbine vane cooling structure trailing edge region. The purpose of this paper is to study the effects of dimple depth and duct converging angle on the endwall heat transfer and friction factor in this pin fin wedge duct. Design/methodology/approach - The study is carried out by using the numerical simulat
The evolution of surfaces exposed to an aggressive environment and mechanical load is studied. The evolution is the initial part of a stress corrosion process that leads to pitting, crack initiation and growing cracks. In conventional fracture analyses the growth rate of the crack may be computed using a modified Paris' law. However, a known or a postulated crack is required. A serious drawback is
Två förslag till en bättre publiceringsverksamhet vid Område HT och vid Lunds universitet. Rapport från projektet HT-områdets bokpubliceringar. Rapporten innehåller förutom de två förslagen också kort historisk bakgrund, nationell och skandinavisk jämförelse och inventering av HT-forskarnas publiceringar. Dessutom sammanfattas två väsentliga internationella diskussioner: hur universitetsförlagen
In a joint project between the Swedish Civil Aviation Administration (SCAA) and Lund University, questions concerning organizational aspects - such as organizational climate, team climate, situational leadership, psychosocial working environment - and safety culture are under study. A team-based organization has recently been introduced and a new air traffic control system will soon be installed a
BACKGROUND: Coarctation of the aorta coexists with other cardiac anomalies and has long-term complications, including recoarctation, which may require intervention after the primary coarctation repair. This study aims to clarify the prevalence of and risk factors for interventions related to the coarctation complex as well as late mortality in a large contemporary patient population. METHODS AND R
Background: Out-of-hospital cardiac arrest (OHCA) is a leading cause of death. Even if successfully resuscitated, mortality remains high due to ischemic and reperfusion injury (I/R). The oxygen deprivation leads to a metabolic derangement amplified upon reperfusion resulting in an uncontrolled generation of reactive oxygen species in the mitochondria triggering cell death mechanisms. The understan
The concentrations of water dimer are compared in Ne and p-H-2 matrices at low temperatures, using infrared spectroscopy. Additional data are given for o-D-2 and Ar matrices. For a given monomer concentration, the dimer concentration is significantly higher in solid Ne (or Ar) than in solid p-H-2. In p-H-2, the dimer concentration is only slightly higher than expected for a random distribution of
A strategy for generating potential galectin inhibitors was devised based on derivatization at the C-3′ atom in 3′-amino-N-acetyllactosamine by using structural knowledge of the galectin carbohydrate recognition site. A collection of 12 compounds was prepared by N-acylations or N-sulfonylations. Hydrophobic tagging of the O-3 atom in the N-acetylglucosamine residue with a stearic ester allowed rap
Popular Abstract in Swedish Istället för fred gav det kalla krigets slut upphov till nya säkerhetspolitiska utmaningar i form av inomstatliga konflikter. Under perioden 1989-2000 utkämpades 111 väpnade konflikter runt om i världen varav de flesta kan karakteriseras som inomstatliga, såsom inbördeskriget i Somalia, det våldsamma sammanbrottet i Jugoslavien, och folkmordet i Rwanda. Trots att både hThis study is concerned with tracing the process of how conflict prevention is moving from the realm of ideas to the field of action. Why is it that, despite historical as well as recent evidence of the infeasibility to prevent wars, the idea of conflict prevention has resurfaced to meet the challenge of the new wars of the post-Cold War era? The study investigates whether the growing interest in
A runtime system for implementation of image processing operations is presented. It is designed for working in a flexible and distributed environment related to the software architecture of a newly developed UAV system. The software architecture can be characterized at a coarse scale as a layered system, with a deliberative layer at the top, a reactive layer in the middle, and a processing layer a
Från och med den 1 januari 2020 skärptes straffskalan för sexköp av barn. Syftet med åtgärden var att förstärka det straffrättsliga skyddet för ungdomar mot att dras in i prostitution. Brottet är förknippat med låg åtalsfrekvens. Det har tidigare förklarats med att aktsamhetskravet i förhållande till ålder i 6 kap. 13 § BrB - som täcker flera sexualbrott med åldersgräns - var särskilt svårt att upIn January 2020 the range of punishment for exploitation of a child through the purchase of a sexual act got stricter. The reasoning behind the change was to strengthen the criminal justice protection for these children. Exploitation of a child through the purchase of a sexual act is associated with a low prosecution frequency. An explanation for this has been that the rule of negligence in the si
This essay examines the philosophical questions posed in Virginia Woolf’s famous novel Mrs Dalloway (1925) set in London in the aftermath of World War I. In her unique tone and poetic aesthetics, Woolf deals with questions about war and its aftermaths, evil and oppressive power, time and temporality, duality of life, fear of suffering and death, sacrifice and suicide but also, most importantly, lo
The aim of this thesis is to study the flammability and fire spread for textile membranes for weather protection. This thesis includes literature studies to determine current standards and recommendations available. Main focus however have been on the European classification system EN 13501-1 and construction site safety. Two types of experimental tests have been done, cone calorimeter test and te
