Background: The ankle–brachial index (ABI) is the ratio of the ankle and brachial systolic blood pressures. In the clinical setting, low ABI (< 0.9) is an indicator of peripheral atherosclerosis, while high ABI (> 1.4) is a sign of arterial stiffness and calcification. The purpose of the current study was to investigate the association between ABI and physical activity levels, measured by accelero

Karin Zackari, universitetslektor i mänskliga rättigheter, visar i sina tillbakablickar att även om universalismen framstår som det svagaste argumentet i samtidens politik, så finns det ett akut behov av en politisk universalism som kommer till uttryck genom konflikter och handlingar. Zackari fokuserar särskilt på den franska filosofen Étienne Balibars intervention i debatten om universalismens mö

The legendary cruise of H.M.S. Challenger (1872-1876) around the globe must always occupy an eminent place in the annals of oceanography, as being the first systematic attempt made on a global scale to explore the ocean. This expedition made fundamental discoveries in biology and geology which have not been surpassed by any later scientific cruise. Sediment with high content of metals (later calle

Non-traditional stable isotope systems are increasingly used to study micronutrient cycling and acquisition in terrestrial ecosystems. We previously proposed for zinc (Zn) a conceptual model linking observed isotope signatures and fractionations to biogeochemical processes occurring in the rice soil environment and we suggested that 2’deoxymugineic acid (DMA) could play an important role for rice

We present the organization, instrumentation, datasets, data interpretation, modeling, and accomplishments of the multinational global atmospheric measurement program AGAGE (Advanced Global Atmospheric Gases Experiment). AGAGE is distinguished by its capability to measure globally, at high frequency, and at multiple sites all the important species in the Montreal Protocol and all the important non

Two of the key functions of arteries in the brain are (1) the well-recognized supply of blood via the vascular lumen and (2) the emerging role for the arterial walls as routes for the elimination of interstitial fluid (ISF) and soluble metabolites, such as amyloid beta (Aβ), from the brain and retina. As the brain and retina possess no conventional lymphatic vessels, fluid drainage toward peripher

Stroke is one of the leading causes of death and disability, yet the cellular response to the ischemic insult is poorly understood limiting therapeutic options. Brain pericytes are crucial for maintaining blood-brain barrier (BBB) integrity and are known to be one of the first responders to ischemic stroke. The exact timeline of cellular events after stroke, however, remains elusive. Using the per

Purpose: The aim of the study is to investigate the association between serum levels of cortisol and erectile function in healthy men aged 45-60 years.Material and methods: The serum level of cortisol was measured. The international index of erectile function-5 items (IIEF-5) was used to assess the erectile function.Data were gathered on the age of participants, Body Mass Index (BMI), waist circum

Social media platforms open up new methods of candidate messaging, voter contact, and data acquisition. Currently, affordances is a popular concept used to study the relationship between political campaigns and how they use social media platforms. Scholars argue that since platforms have different designs, they offer different affordances that affect how campaigns use social media. This chapter ev

Atmospheric observations and trends are presented for the high molecular weight perfluorocarbons (PFCs): decafluorobutane (C 4F 10), dodecafluoropentane (C 5F 12), tetradecafluorohexane (C 6F 14), hexadecafluoroheptane (C 7F 16) and octadecafluorooctane (C 8F 18). Their atmospheric histories are based on measurements of 36 Northern Hemisphere and 46 Southern Hemisphere archived air samples collect

Odlingstekniken monokultur bygger på en ekonomisk rationalism som säger att hela odlingsytan ska upptas av den gröda eller det trädslag som är föremål för markägarens kommersiella intresse. Därtill ska all annan växtlighet betraktas som ett ogräs som konkurrerar med odlingsverksamheten om ljus, näring och utrymme. Monokulturen, samt dess ekonomiskt-rationella motivering, dominerar idag odlingsland

Det finns en mångfald av olika sorters ytor, men en speciell delmängd av dem, de kompakta och sammanhängande, kan beskrivas i sin helhet av objekt som kallas schema. Det är med dess schema och deras egenskaper som vi kommer att bevisa vårt huvudresultat; Att all sådana ytor kan beskrivas av tori, projektiva plan eller sfären.The study of surfaces is a specific subcategory of manifolds. In simpler terms, surfaces are topological spaces which are locally similar to the plane. One may think of a sphere, a cube or a donut. There has long been a desire to classify all of these surfaces, and the goal of classifying a certain subset, the compact and connected ones, go back to 1861 when möbius tried. Unfortunately he did not

We theoretically investigate nondipole effects in the reconstruction of attosecond beating by interference of two-photon transitions (RABBIT) of helium using linearly polarized extreme ultraviolet and infrared fields. By scanning the time delay between the two fields, we observe modulations in sidebands (SBs) both for angular-integrated photoelectron yield and forward-backward asymmetry in photoel

Hur speglar användbarhetsproblem den upphandlade kravställningen? Vad är det viktigaste att kravställa inom digitala verksamhetssystem och hur görs det på bästa sätt? Det är frågorna som detta projekt har undersökt genom att utvärdera ett digitalt verksamhetssystem i två olika kommuner i Sverige. Genom intervjuer, enkätundersökningar, och utvärdering av upphandlingsdokumenten undersöktes hur kommu

Source code analysis is ubiquitous in the development of software tools, for example in compilers to detect compile-time errors and possible optimizations, inIDEs to provide interactive coding assistance, and in stand-alone analysis tools todetect bugs. There are several techniques that have been developed to help theanalysis developer, including one called Reference Attribute Grammars (RAGs).With
