Many problems concerning resource management in modern communication systems can be simplified to queueing models under Markovian assumptions. The computation of the optimal policy is however often hindered by the curse of dimensionality especially for models that support multiple traffic or job classes. The research focus naturally turns to computationally efficient bounds and high performance he

BACKGROUND AND AIMS: Autoantibodies against the zinc transporter 8 (ZnT8A) are common in type 1 diabetes (T1D). ZnT8A analyses are complicated by the fact that there are three variants of the autoantigen at amino acid position 325 representing ZnT8-R (Arginine), ZnT8-W (Tryptophan) and ZnT8-Q (Glutamin). The aims of the study were: 1) to develop an autoantigen triple mix Radio-Binding Assay (RBA)

HIV/AIDS stigmatizing behaviors are a huge barrier to early detection and treatment of individuals with the AIDS virus. HIV/AIDS stigma and related consequences are debilitating, especially for vulnerable populations. This study sought to assess whether young women's HIV/AIDS knowledge levels and exposure to mass media (television and radio) have an influence on their stigmatizing behaviors and ro

Issues surrounding relationships between different writings and questions regarding literary dependence are ubiquitous in New Testament scholarship. This study aims to answer questions concerning how one is to understand the way that early Christian writers used other Christian writings: Are any typical characteristics discernible regarding the earliest use of Christian writings? Were they memoriz

Mining, seen as a source of revenue in most developing countries, threatens seriously the environment. Mining impacts the water quality and one of the main problems of mining is acid mine drainage. Low pH and high concentration of heavy metals characterize acid mine drainage. When a stream is impacted by acid mine drainage both human activities and the ecological system are seriously affected. In

BACKGROUND: A growing body of studies indicate benefits of physiotherapy for patients in palliative care, for symptom relief and wellbeing. Though physiotherapists are increasingly acknowledged as important members of palliative care teams, they are still an underutilized source and not fully recognized. The aim of this study was to explore the variety of activities described by physiotherapists i

IntroductionSelf efficacy (SE) relates to pupils' beliefs about their own capacities within a given field. It has been shown that an overestimation of one's own SE beliefs affects learning outcomes negatively. In the present study we examine SE beliefs in writing skills in two groups of secondary school pupils, one with hearing impairment, the other without.PurposeText writing is a complex skill,

Background: Differences in stroke care and health outcomes between men and women are debated. The objective of this study was to explore the relationship between patients' sex and post-stroke health outcomes and received care in a Swedish setting. Methods: Patients with a registered diagnosis of acute intracerebral hemorrhage (ICH) or ischemic stroke (IS) within regional administrative systems (IC

The notion of creative city has been extensively discussed both in academic debate as well as public discourse, including on Asian context. However, a tendency to study only on strategic government policies in relation to this matter has led many multidimensional aspects being left behind. One of these important aspects is the creativity-based activities initiated and conducted by local groups, co

Popular Abstract in Swedish I avhandlingen behandlas de rättsregler som kan tillämpas när banker erbjuder kunder att kommunicera via Internet och lämna betalningsinstruktioner avseende kredittransfereringar på detta sätt. Den här typen av banktjänster benämns i avhandlingen Internet Banking. Betalningar och betalningsinstruktioner är inget nytt fenomen men i avhandlingen behandlas de utifrån ett eThis thesis deals with legal issues arisen from consumer-activated payment orders, regarding credit transfers, which are initiated via the Internet under an agreement (about using Internet-services) previously entered into between the bank and the payer (or the originator). This Internet-service is in the thesis called Internet banking. More and more customers, both consumers and others, activate

The limited IPv4 address space has driven the cellular industry to start using IPv6 addresses for mobile users in 3G-networks. However, there is a potential threat to the success of 3G-network deployment, as the success will depend on the services offering to the end users. Currently, the overwhelming proportion of services resides in the IPv4 address space, which makes them inaccessible to users

This paper contains a theoretically and empirically based analysis of infrastructures and co-operational patterns in a Scandinavian Internet consulting company. The purpose of the analysis originated from the hypothesis that Web-based Information Systems could especially facilitate work in distributed organisations, this as a platform for supporting collaboration, communication and co-ordination w

In acts of memorialisation, the objects that ”help” people get into contact with (their memory of) the deceased – like gravestones, personal collections of the deceased’s paraphernalia, objects placed at sites of sudden death, etc. – are often strictly regulated, differently in different cultures. At ”wrong” spots in the urban environment for instance, memorial places can thus be regarded as highl

Objective: To evaluate efficacy and cost-effectiveness of budesonide/formoterol (Symbicort*) maintenance (one dose once or twice daily) plus additional doses as needed (Symbicort Maintenance And Reliever Therapy, SMART) compared with a higher fixed dose of budesonide/ formoterol with formoterol as needed in patients with persistent asthma. Study design and methods: 6-month, open, randomised study

Background: To linguistically validate and culturally adapt the Evaluation of Daily Activity Questionnaire (EDAQ) for use in rheumatoid arthritis (RA) from Swedish to British English. The EDAQ is a patient reported outcome measure of daily activity ability. It includes 11 activity domains (Eating and Drinking; Personal Care; Dressing; Bathing; Cooking; Moving Indoors; House Cleaning; Laundry; Movi

The aim of this work was to study possible effects of environmental radiation pollution on plants. The association between cellular telephone (short duration, higher amplitude) and base station (long duration, very low amplitude) radiation exposure and the growth rate of soybean (Glycine max) seedlings was investigated. Soybean seedlings, pre-grown for 4 days, were exposed in a gigahertz transvers

Fatty-acyl CoA reductases (FAR) convert fatty acids into fatty alcohols in pro- and eukaryotic organisms. In the Lepidoptera, members of the FAR gene family serve in the biosynthesis of sex pheromones involved in mate communication. We used a group of closely related species, the small ermine moths (Lepidoptera: Yponomeutidae) as a model to investigate the role of FARs in the biosynthesis of compl

Popular Abstract in Swedish Inledning/introduktion: Öppen rekonstruktion av aorta innebär en påtaglig risk för postoperativa komplikationer och dödlighet, särskilt i den äldre befolkningen och i dem som är mindre lämpliga för en sådan stor operation. Endovaskulär aorta kirurgi förefaller säker, hållbar och effektiv när det finns tillräcklig proximal och distal tätningszon för en stentgraft. FenestIntroduction: Open repair of the aorta carries a high risk for morbidity and mortality especially in the elderly population and in patients unfit for major surgery. Endovascular aortic repair is safe, durable and effective when there is adequate proximal and distal sealing zone for the aortic stent graft. Fenestrated and branched stent grafts have made the repair possible for complex but elective

Popular Abstract in Swedish Stora resurser används i processindustrin, och i många andra industribranscher, på att rapportera incidenter för att utnyttja erfarenheterna från dessa för att förebygga framtida incidenter – alltifrån mindre störningar till olyckor med stora konsekvenser. Det finns emellertid en hel del som tyder på att man ofta utnyttjar bara en del av hela den potential för lärande sLearning from incidents (from minor disturbances to major accidents) is considered one of the most important ways in the process industry to learn from experiences for improving safety performance. Most companies have a formal incident learning system and considerable resources are used for reporting incidents and for utilising these experiences to prevent future incidents. However, there are many
