Interaction of synthetic TiO2 (anatase) nanoparticles in aqueous suspension at pH 5 was investigated as a function of time in the presence of various organic molecules in terms of adsorption and aggregation behaviour. ζ-potential and average particle diameter were determined with electrophoretic and dynamic light scattering, respectively, while batch adsorption experiments were used to quantify th
The Transiting Exoplanet Survey Satellite (TESS) will provide high-precision time series photometry for millions of stars with at least a half-hour cadence. Of particular interest are the circular regions of 12° radius centred around the ecliptic poles that will be observed continuously for a full year. Spectroscopic stellar parameters are desirable to characterize and select suitable targets for
In Sweden, almost half of the electricity produced comes from hydropower. However, the amount of water in the reservoir catchments is not evenly distributed throughout the year. During the colder months, precipitation usually falls as snow and accumulates into a snowpack. This frozen water is not available to the energy producers until the spring snow melt when as much as 70% of the annual dischar
The global CO2 emissions in 2010 from fossil energy use grew at the fastest rate since 1969. The year 2010 also witnessed that the global oil production did not match the rapid growth in consumption [1]. These recent data further intensify worldwide concerns about greenhouse gas emissions and energy security for a sustained economic development. For a reduced dependence on oil from fossil reserves
An international panel of experts representing 17 European countries and Israel convened to discuss current needs and future developments in BRCA testing and counselling and to issue consensus recommendations. The experts agreed that, with the increasing availability of high-throughput testing platforms and the registration of poly-ADP-ribose-polymerase inhibitors, the need for genetic counselling
BACKGROUND: The discovery that heterozygous missense mutations in the gene encoding triggering receptor expressed on myeloid cells 2 (TREM2) are risk factors for Alzheimer's disease (AD), with only the apolipoprotein E (APOE) ε4 gene allele conferring a higher risk, has led to increased interest in immune biology in the brain. TREM2 is expressed on microglia, the resident immune cells of the brain
The purpose in this paper is to show how public procurement can be a driver ofinnovation. The purpose and point of departure when using public procurement as an instrument of innovation policy is always to solve societal and environmental problems, to satisfy human needs or to meet global challenges. The paper is aimed at everyone who is involved or interested in public procurement, and especially
Lake ice is a robust indicator of climate change. The availability of information contained in Moderate Resolution Imaging Spectroradiometer daily snow products from 2000 to 2017 could be greatly improved after cloud removal by gap filling. Thresholds based on open water pixel numbers are used to extract the freezeup start and breakup end dates for 58 lakes on the Tibetan Plateau (TP); 18 lakes ar
BACKGROUND: Hypoglycemia is one of the most common metabolic derangements in childhood. To establish the cause of hypoglycemia, fasting tolerance tests can be used. Currently available reference values for fasting tolerance tests have limitations in their use in daily practice. OBJECTIVE: The aim of this study was to determine the reference values of metabolites involved in glucose homeostasis dur
This paper focuses on carbon, which is one of the most abundant elements in the universe and is of high importance in the field of nucleosynthesis and galactic and stellar evolution. The origin of carbon and the relative importance of massive and low-to intermediate-mass stars in producing it is still a matter of debate. We aim at better understanding the origin of carbon by studying the trends of
Många sjukdomar som inte beror på virus eller bakterier kopplas ofta till genetik. Vår förståelse kring hur gener påverkar vår hälsa har ökat dramatiskt med molekylärbiologins framfart. Sedan 1930-talet har det utvecklats nya tekniker för att tyda gener och dess DNA. Länge var gener ett ganska abstrakt koncept, man visste att det fanns något som fördes vidare genom generationerna men inte exakt vaTo find true genetic associations in complex diseases, such as allergic rhinitis and chronic rhinosinusitis, is a difficult task. Both are polygenetic diseases where it is believed that genetic variation in several genes make up their phenotypes. In addition, the environment of the affected individuals also play an important role, further obscuring eventual associations. Today most genetic associa
Cartilage glycosaminoglycan (GAG) synthesis and composition, upon which its structural integrity depends, varies with age, is modified by anabolic and catabolic stimuli, and is regulated by UDP-glucuronate availability. However, how such stimuli, prototypically represented by transforming growth factor-beta1 (TGF-beta1) and IL-1alpha, modify GAG synthesis during aging of normal human articular car
In recent years, land acquisition has escalated due to increased global demand for food and fuel driven by population growth, urbanisation, and growing energy demand. Mozambique is ranked as one of the world’s top 10 countries with available land for agriculture, forestry and livestock production. Low labour costs and land taxes may further increase the interest in Mozambican land. In particular,
Generellt i samhället, såväl bland allmänheten som i rättssystemet, har det konstaterats att det finns en misstro mot kvinnor som anmäler våldtäktsbrott. En återkommande föreställning är att kvinnor ljuger om vad som inträffat när de anmäler dessa brott. Vidare har den svenska våldtäktsprocessen nyligen kritiserats för att innehålla negativa föreställningar om kvinnor. I denna uppsats undersöker jIn public opinion, as well as in the legal system, there is a general disbelief of those who report rape. This distrust is partially founded on a reoccurring perception that women often lie when reporting crimes of sexual violence. The Swedish legal process has recently been subject to critique for holding negative perceptions about women in rape related court cases. In this study I examine if and
Even though flying is the most unsustainable mode of transport due to its high contribution to global climate change (global warming), it is widely used and is predicted to increase considerably in the future. This goes against the global goal to reduce greenhouse gas (GHG) emission in order to reach the two-degree target set in the Paris Agreement. I am addressing this problem by looking into the
Halvledarindustrin har en form av immaterialrätter avsedd särskilt för dem: Kretsmönsterrätter. Dessa introducerades i USA 1984 i syfte att skydda den amerikanska halvledarindustrin från konkurrens från östra Asien, huvudsakligen Japan. Den ersatte principen om nationell behandling med den materiella ömsesidighetsprincipen, som är normen inom immaterialrätt. Detta tillät USA att tvinga andra ländeThe semiconductor industry has a sui generis IP type dedicated to it: the semiconductor topography right. This right was introduced in 1984 with the purpose of protecting the U.S. semiconductor industry from East Asian, mainly Japanese, competition. It replaced the principle of treatment on a national basis that is the norm in IP law with one of material reciprocity, which allowed the U.S. to stro
Structured follow-up after revascularisation for chronic critical limb ischaemia (CLI) aims at sustained treatment success and continued best patient care. Thereby, efforts need to address three fundamental domains: (A) best medical therapy, both to protect the arterial reconstruction locally and to reduce atherosclerotic burden systemically; (B) surveillance of the arterial reconstruction; and (C
Laminar burning velocity of lean hydrogen + air flames at standard conditions is still a debated topic in combustion. The existing burning velocity measurements possess a large spread due to the use of different measurement techniques and data processing approaches. The biggest uncertainty factor in these measurements comes from the necessity to perform extrapolation to the flat flame conditions,
Närheten till vatten är viktigt för många av oss människor. Vatten som i sjöar och hav kan ge både avkoppling och ro, något att titta på i stillsamhet, något att uppleva i storm, något att åka på. Men ligger inte den starkaste upplevelsen av vatten i den fysiska kontakten? Att vara i vattnet, det är något som saknas i en stad som byggts vid, närt sig på och formats av vatten. I en stad som Götebor
