With the aid of time-resolved dynamic light scattering (DLS) and static light scattering (SLS), we have analyzed the ejection kinetics from the bacterial virus bacteriophage (or phage) lambda, triggered in vitro by its receptor. We have used DLS to investigate the kinetics in such a system. Furthermore, we have shown that both SLS and DLS can be interchangeably used to study the process of phage D
Traditionally, the majority of Swedish public libraries have carried out most of their acquisitions through Bibliotekstjänst's binding booklets. In recent years, however, many libraries have complemented the binding booklets and other services from Bibliotekstjänst by other ways of acquiring books, such as Internet bookshops, while other libraries have stopped using the binding booklets altoge
In 2010 there will be a political resolution to ensure that the Swedish society is accessible to all citizens including people with disabilities. For this purpose a national action plan for disability policy "From patient to citizen" (Govt. Bill 1999/2000:79) has been set out with the aim of ensuring that the disability perspective will permeate every sector of society and that the appro
BACKGROUND: Individuals with spinal cord injury (SCI) now live longer, which increases the risk of cardiovascular disease. Knowledge of cardiovascular risk factors amenable to intervention are therefore needed to support their healthy aging. OBJECTIVE: To describe the occurrence of cardiovascular risk factors among older adults with long-term SCI and investigate the association with sociodemograph
Over the past few decades, lean management philosophies have penetrated various sectors of industry. At same time, dynamic environmental, or green, management is needed to succeed in the current green conscious market. Some research has already been conducted on the potential synergy gains of the two management philosophies, since both are known to strive towards efficient use of resources, elimin
Background: Block-sequential regularized expectation maximization (BSREM), commercially Q. Clear (GE Healthcare, Milwaukee, WI, USA), is a reconstruction algorithm that allows for a fully convergent iterative reconstruction leading to higher image contrast compared to conventional reconstruction algorithms, while also limiting noise. The noise penalization factor β controls the trade-off between n
Background: Parkinson's disease (PD) is the second most common neurodegenerative disease, affecting similar to 5.2 million people worldwide. Continuous subcutaneous apomorphine (CSAI) represents an alternative treatment option for advanced PD with motor fluctuation. The purpose of this analysis was to estimate the cost-effectiveness of CSAI compared with Levodopa/carbidopa intestinal gel (LCIG), D
Context The relationship of platelet function testing measurements with outcomes in patients with acute coronary syndromes (ACS) initially managed medically without revascularization is unknown. Objective To characterize the differences and evaluate clinical outcomes associated with platelet reactivity among patients with ACS treated with clopidogrel or prasugrel. Design, Setting, and Patients Pat
Reproductive success usually declines in the course of the season, which may be a direct effect of breeding time, an effect of quality (individuals with high phenotypic or environmental quality breeding early), or a combination of the two. Being able to distinguish between these possibilities is crucial when trying to understand individual variation in annual routines, for instance when to breed,
Popular Abstract in Swedish I debatterna om sociala och ekonomiska frågor under 1800-talets första hälft utvecklades grundvalarna för de förhållningssätt till arbetslöshetsfrågan som sedan återkommit i skilda former. Det gällde t.ex. det perspektiv som betonade politikens roll och behovet av statlig intervention för att stimulera produktion och sysselsättning. Det gällde också det renodlade marknaLabour market policy has been at the forefront of economic and political debate in Sweden during the postwar period. Much research effort has been focused on the evolution of labour market policy and its historical roots. The time-perspective has often been narrow, however, and has very seldom extended to include the period prior to the first two decades of the twentieth century. This study emphas
Popular Abstract in Swedish I EU-tider är det viktigt att inte bara studera EU-rätten och dess applicering på svenska förhållanden. Det är också viktigt att skaffa och öka kunskapen om förhållanden i de andra medlemsstater som är med om att förhandla fram EU:s arbetsrätt. En viktig skillnad mellan medlemsstaterna är hur relationerna mellan de kollektiva aktörerna på arbetsmarknaden, industrial relThis work is a study in sociology of law about working time regulation in France, Sweden, Denmark and the United Kingdom during the industrialised era. The purpose is to study changes, developments and the role of law in the working time regulation process. Way back there is an element of repressive law, following the law tradition from the feudal society. The repressive law punishes the extreme a
The establishment of e-businesses has often been implemented from the inside of companies rather than from the customer perspective and the knowledge about customer needs from traditional businesses have been applied directly into new e-business systems. The overall objective of this study is to identify how to better understand customer needs and how to integrate these needs in order to create cu
What are the social positions of adults who were in long-term foster care as children, compared with the general population and with adults who grew up at home in families similar to foster children's birth families? How common is it to have been in foster care? Four approaches are used in this study: - A systematic review of around 50 studies on adult foster children. Conclusions are more pessim
Popular Abstract in SwedishKontraktsstyrning i teori och praktikUnder de senaste decennierna har användningen av kontraktsstyrning ökat i både privat och offentlig sektor. Det finns ett stort intresse för styrformens egenskaper. Kontraktsstyrning diskuteras ibland som en tredje form av styrning, en sorts mellanform av idealtyperna marknad och hierarki. Frågan är dock vad som karaktäriserar denna sThe general aim of this thesis is to develop an increased understanding of contract management as a mode of governance. A specific aim has been to explore how complex municipal services are managed by contract. A framework for analysis of contract management was developed by combining elements from interorganisational theories with different perspectives, such as transaction cost theories, network
Plant species beta diversity is influenced by spatial heterogeneity in the environment. This heterogeneity can potentially be characterised with the help of remote sensing. We used WorldView-2 satellite data acquired over semi-natural grasslands on The Baltic island of Öland (Sweden) to examine whether dissimilarities in remote sensing response were related to fine-scale, between-plot dissimilarit
Popular Abstract in Swedish Vid en knäprotesoperation ersätts ledytorna i knäet med en protes gjord av metall och plast. Den vanligaste orsaken till denna operation är artros(ledsvikt. Antalet knäprotesoperationer ökar stadigt och 2009 utfördes 12,700 förstagångsoperationer i Sverige. Resultaten är överlag goda men en allvarlig komplikation som drabbar mellan 1 och 2% av patienterna är bakterieinf
Background The clinical effect of routine intracoronary thrombus aspiration before primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) is uncertain. We aimed to evaluate whether thrombus aspiration reduces mortality. Methods We conducted a multicenter, prospective, randomized, controlled, open-label clinical trial, with enrollment of
Popular Abstract in Swedish En central frågeställning inom ekologin handlar om hur och varför organismers utbredning och antal varierar i tid och rum. Detta forskningsfält går under namnet populationsdynamik och är ämnet för min avhandling. Populationsdynamik handlar om mönster, slumpmässighet, förändringar; helt enkelt matematik! Av den anledningen är det inte bara önskvärt, utan faktiskt nödvändPopulation dynamics in space and time are manifested as changes in the distribution and abundance of organisms. To couple such patterns to the underlying processes is a central question in ecology and also key to successful management. In this thesis, I use theoretical models as well as time series data to analyze population dynamics in environments that are variable in space or time. An example o
Since the development of real-time PCR, the technology has been widely applied in the field of diagnostics. In comparison with conventional PCR it has opened up the possibility of accurate quantification of microorganisms in clinical, environmental and food samples. When employing real-time PCR and absolute quantification in biological samples, five important requirements should be fulfilled, name
The people bordering the Arabian Gulf, the Mediterranean Sea and the Red Sea rely more and more on seawater desalination for safe water supply. Desalination has advantages and disadvantages which to a large extent depend on the region, location, technology, impact and amount of fresh water production. In this region, some 60% of all desalination capacity is installed. The three regions areas repre
