A lot of money is being spent by the governments all over the world in developing and deploying Government to Citizen (G2C) e-government applications. These applications serve the purpose of providing better civic services to the citizens. The success of such applications is frequently heard and witnessed in the developed countries but there is a prevailing concern about the success and adoption o
The thesis is done for the company Gambro which manufactures dialysis products worldwide. The idea of this thesis is to investigate weaknesses of the communication protocol which is used in one of the Gambro dialysis machines, Prismaflex and thereby investigate opportunities to improve the system by using other protocols. The thesis is divided into three major parts. They are the study of Prismafl
Detta arbete handlar om att utveckla och förbättra en försöksuppställning som kan mäta laserinducerad fosforescens både spektralt och tidsupplöst. Ämnet som emitterar fosforescensen befinner sig i en kalibreringsugn som kan värmas till olika temperaturer vilket möjliggör studier av irreversibla åldringsprocesser i ämnet som funktion av temperatur och tid. Fosforescens är den långa efterglöd som fo
Barley is an abundant crop in Europe, which makes its straw residues an interesting cellulose source for ethanol production. Steam pretreatment of the straw followed by enzymatic hydrolysis converts the cellulose to fermentable sugars. Prior to pretreatment the material is impregnated with a catalyst, for example, H2SO4, to enhance enzymatic digestibility of the pretreated straw. Different impregn
Spinocerebellar ataxia type 3 (SCA3), caused by a CAG repeat expansion in the ataxin-3 gene (ATXN3), is characterized by neuronal polyglutamine (polyQ) ATXN3 protein aggregates. Although there is no cure for SCA3, gene-silencing approaches to reduce toxic polyQ ATXN3 showed promise in preclinical models. However, a major limitation in translating putative treatments for this rare disease to the cl
This article reviews the problem of bleeding in connection with epidural/spinal anaesthesia, with special emphasis on the use of low molecular weight heparins for thromboprophylaxis. There are methodological difficulties to studying the problem in a scientifically correct way because of the rarity of the complication. However, from the data in the literature there are no indications of an increase
A box graph is the intersection graph of orthogonal rectangles in the plane. We consider such basic combinatorial problems on box graphs as maximum independent set, minimum vertex cover and maximum induced subgraph with polynomial-time testable hereditary property Pi. We show that they can be exactly solved in subexponential time, more precisely, in time 2(O(rootnlog n)), by applying Miller's simp
In the water sector, there have been numerous failures in projects aiming at sustainable development and there have been some, but less numerous, examples of successes. However, the most striking observation is the near universal failure to learn from these examples. Somehow, scientists and decision makers have allowed the indications of new approaches and opportunities go undetected because they
Abstract BACKGROUND: Family history has been suggested as a risk factor for varicose veins, but recall bias may inflate the familial risks. The aim of this nationwide study was to determine familial risks for hospital treatment for varicose veins. METHODS: Data from the Swedish Multi-Generation Register of people aged 0-76 years were linked to Hospital Discharge Register data for 1964-2008. Stand
Triglycerides are transported in plasma by specific triglyceride-rich lipoproteins; in epidemiological studies, increased triglyceride levels correlate with higher risk for coronary artery disease (CAD). However, it is unclear whether this association reflects causal processes. We used 185 common variants recently mapped for plasma lipids (P < 5 x 10(-8) for each) to examine the role of triglyceri
The European Commission stresses the importance of Small and Medium-sized Enterprises (SMEs) for the European economy. SMEs are held to be the "backbone" of the European industry and their prosperity will enable the EU to reach the Lisbon strategy's goals about growth and competitiveness. Yet large enterprises are normally seen as the influential business interests in European policy
To avoid eutrofication and excessive algal bloms it is necessary to reduce the phosphorus contents in wastewater. Previous wastewater treatment systems often have a good process for phosphorus reduction but in general not the ability to recycle the material and phosphorus for further utilisation after its use in wastewater treatment. Polonite® is a material with large content of calciumoxide wh
The philosophy of social science is today, from the perspective of the scientists themselves, dominated by the notions of quantitative and qualitative research. Social scientists make distinctions between a wide range of different aspects of research in terms of what is quantitative and qualitative. The purpose of this paper is to integrate these distinctions into a useful conceptualization. First
The biotechnology industry is an evolving sector of this century having potential to significantly influence our lives. It has unidentified potentials to contribute to sustainable development, but is also feared by society for its possible known and unknown impacts. Amplified transparency brought about by media, new concerns and expectations of society towards business as well as social criteria a
The importance of gender differences during conflict and peace-building have raised as a specific area of study both in the academy as well as among global institutions such as the UN. Among those, there is almost a pre-assumption that strengthening women's movements is positive for a peaceful and just solution. However, they fail to address the complex relationships between the conflicting pa
Det finns runt 100 000 blinda och kraftigt synnedsatta individer (BKSI:er) i Sverige. Sådan synnedsättning leder till en kraftigt minskad förmåga för självständig förflyttning och lägre livskvalité, med ökad risk för arbetslöshet, trafikolyckor, en stillasittande livsstil och depression. Hälften av alla käpp- och hundanvändare är med om en huvudkollision årligen, och drygt var tredje för en fallolReduced independent mobility of blind and low-vision individuals (BLVIs) cause considerable societal cost, burden on relatives, and reduced quality of life for the individuals, including increased anxiety, depression symptoms, need of assistance, risk of falls, and mortality. Despite the numerous electronic travel aids proposed since at least the 1940’s, along with ever-advancing technology, the m
Although photothermal therapy is of significance in therapeutic strategies for fighting bacterial infection, the precise target of photothermal agents to bacterial sites is still a challenge. In this work, lipopolysaccharide (LPS) imprinted photothermal molecularly imprinted polymers (PMIP) were prepared for the efficient capture and elimination of Pseudomonas aeruginosa. The LPS derived from Pseu
Local flexibility markets (LFM) for electricity are in their early stages, and most research has focused on their design aspects and aggregators, while little attention has been paid to providers and potential providers of flexibility resources. The present research aims to fill this gap by analysing data from 25 in-depth interviews with enrolled and potential flexibility service providers of two
