Analysis of heart rate variability using time-varying frequency bands based on the respiratory frequency

In this paper a methodological approach for the analysis of nonstationary heart rate variability (HRV) signals using time-varying frequency bands based on respiratory frequency is presented. Spectral analysis of HRV is accomplished by means of the Smoothed Pseudo Wigner Ville distribution. Different approaches to the definition of the low frequency (LF) and high frequency (HF) bands are considered

Regional utveckling - tillväxt och demokrati i förändring

Utifrån ett tjugotal intervjuer med tjänstemän, politiker och näringslivsrepresentanter tecknar författaren en bild av den regionala utvecklingen i Kalmar och Skåne. Rapportens syfte är att identifiera debatten och resonemangen kring försöksregionerna, på nationell, regional och i viss mån kommunal nivå. Två teser drivs. För det första undersöks om det finns ett demokratiskt underskott samt tjänst

The Structure-Function Relationship and Evolution of Deoxyribonucleoside Kinases

Popular Abstract in English Deoxyribonucleoside triphosphates (dNTPs) are the building blocks of DNA and the balanced cellular dNTP pools are of extreme importance to maintain the genomic stability and overall function of the cell. Primarily, two different pathways exist in most of the organisms that are responsible for providing dNTPs. One is called the de novo pathway where dNTPs are formed fromThe synthesis of deoxyribonucleoside triphosphates (dNTPs), building blocks of DNA, can be achieved by two different pathways in the cell. One is called de novo synthesis and the other is known as salvage pathway. The de novo pathway involves synthesis of dNTPs by utilizing basic molecules like sugars, amino acids, CO2, NH3, etc., while in the other pathway, dNTPs are formed by salvaging intra- or

Digestion and absorption of galactolipids

Popular Abstract in Swedish TARMENS UPPTAG AV GALAKTOLIPIDER Världens vanligaste fettmolekyler Inuti cellerna hos alla växter finns en komponent som kallas kloroplast. I kloroplasten sker den livsviktiga fotosyntesen där energi från solljuset omvandlar koldioxid och vatten till socker och syre. Inuti kloroplasten finns en stor mängd membraner som kan liknas vid en bunt platta säckar. Genom dessa Galactolipids: digalactosyldiglyceride (DGalDG), monogalactosyldiglyceride (MGalDG) and sulfoquinovosyldiglyceride (SQDG) are the major lipid components in thylakoid membranes of chloroplasts i.e. the site of photosynthesis in plants. They are the most abundant membrane lipids in nature, and thus important sources of essential fatty acids for herbivores and omnivores. This thesis investigates the

Berättelser om mutor : Det korruptas betydelse bland svenska affärsmän i Öst- och Centraleuropa

Popular Abstract in Swedish Vad innebär det att muta någon? Vad är egentligen en muta? Denna studie har motiverats av sådana frågor. Det centrala argumentet är att mutor och korruption inte enbart tillhör ett samhälles juridiska sfär utan även dess sociala och moraliska. Om ett agerande ska anses korrupt eller hederligt, klandervärt eller klanderfritt (eller någonting däremellan) avgörs inte enbarWhat does it mean to bribe someone? What is the meaning of bribes? Questions like these have motivated this study. Its central argument is that the folk meanings of “bribes” and “corruption” depend on people’s symbolic demarcations and definitions. Corruption is something we actively define as well as something through which we define ourselves. A specific case has been used: stories about bribes

Socio-Cultural Retailing: A literature review

The aim of this paper is to contribute to the cultural turn in retail studies by offering an overview of the interdisciplinary field of socio-cultural retailing and, based on this introduction, draw out and discuss what this body of work can contribute to the field of retail marketing. The paper reviews socio- cultural retail research from the disciplines of marketing, cultural geography, sociolog

Structural and functional analyses of infectious pancreatic necrosis virus (IPNV)

Infectious pancreatic necrosis virus (IPNV) is a naked virus of an uncomplicated structure. In the interior part of the virion, the two segments of double-stranded RNA are located together with the minor structural protein VP1. This protein is detected in its free form as well as linked to the genome. A polymerase activity has been assigned for VP1. The localisation of the viral protein VP3 has a

Scaling of proton acceleration driven by petawatt-laser-plasma interactions

The possibility of using high-power lasers to generate high-quality beams of energetic ions is attracting large global interest. The prospect of using laser-accelerated protons in medicine attracts particular interest, as these schemes may lead to compact and relatively low-cost sources. Among the challenges remaining before these sources can be used in medicine is to increase the numbers and ener

Function via structure in vivo and in modeling

Popular Abstract in Swedish Proteinstrukturmodellering-att gissa struktur och funktion (artikel I och manuskript I) Proteiner har många funktioner i cellens komplicerade maskineri. Ett protein består kemiskt av en rad sammmanlänkade byggstenar, aminosyror, varav det finns 20 olika mest förekommande. En proteinkedja viker ihop sig enligt ett speciellt mönster för att och bilda ett funktionellt proKnowledge of biomolecules three-dimensional structure has provided a detailed understanding of their function. In recent years the number of new protein sequences has far exceeded the number of protein experimental structure determinations. One goal of the new field of protein structural bioinformatics is to provide reliable and automated protein functional annotations and initial protein structur
