The outstanding success of structural biology within the last two decades is closely related to the development and evolution of macromolecular crystallography (MX) beamlines. Indeed, many of today's synchrotron-based MX experimental sessions aim for fast but rigorous evaluations and data collections from very large numbers of samples [1–7]. To facilitate this, sample changing on most MX beamlines
Objective: To determine the importance of antibodies against phosphorylcholine (PC) and oxidized low density lipoprotein (OxLDL) for development of atherosclerosis. Methods and results: Two hundred and twenty six individuals with established hypertension (diastolic pressure > 95 mmHg) were from European Lacidipine Study on Atherosclerosis. Antibodies of IgG and IgM subclass were tested by ELISA ag
The use of amino acids for the synthesis of novel surfactants with vesicle-forming properties potentially enhances the biocompatibility levels needed for a viable alternative to conventional lipid vesicles. In this work, the formation and characterization of catanionic vesicles by newly synthesized lysine- and serine-derived surfactants have been investigated by means of phase behavior mapping and
We find that CO ligates selectively to nitrogen tetra-coordinated Co(i) single metal atom sites at room temperature in a manganese–cobalt bi-metallic coordination network self-assembled on graphene. The bound state is metastable, determined by pressure-dependent equilibrium conditions between adsorption and desorption, with an upright, end-on bonding geometry (binding energy 0.73 eV). The ligand v
Klimatförändringar är ett av vår tids största miljöhot. Medan länderna i Nord står för de högsta utsläppen är det människorna i Syd som får bära den största bördan. Massajer med sin nomadiska historia konfronteras med svårigheter, då de utöver ett föränderligt klimat måste anpassa sig till ett bofast liv med mindre mark. I massajernas genussystem är mäns och kvinnors roller tydligt uppdelade där mClimate change is one of our greatest environmental threats. While the countries of the North are responsible for the highest emissions, it is the people in the South who bear the greatest burden. In addition to climate change, the Maasai have to adapt to their sedentary life, including less land. In the Maasai gender system, the chores are clearly divided between men and women, with men holding t
Kvinnans förhållande till sitt eget mytiska arv är ett komplicerat sådant, som Beauvoir förklarar: ”representation of the world, like the world itself, is the work of men; they describe it from their point of view, which they confuse with absolute truth.” Alienation från sin egen historia har lett till en lång tradition av kvinnliga författare som tacklas med sitt mytiska arv för att försöka hitta
Background Axis is a network surveillance company, based in Lund, Sweden. Axis has outsourced its production to contract manufacturers which are positioned in different parts of the world. Axis’ suppliers are also spread across the globe. During the last years, Axis has experienced several supply disruptions from its suppliers and contract manufacturers, due to natural and technological disasters.
Unlimited vacation policies are a rising trend, particularly among startup and tech companies. Giving employees total freedom to choose their vacation days may prove to be beneficial for both company and employees. Within this paper, a qualitative research is presented, with the objective of finding out how unlimited vacation policies (UVPs) influence job satisfaction among employees, and what imp
Kemi är en viktig del i våra dagliga liv och den är fylld med många invecklade processer och mekanismer. Några av oss kanske kommer ihåg tumregeln ”lika löser lika” från kemiundervisningen. Detta påstående stämmer i de flesta sammanhangen inom kemin och kan i vissa fall leda till problem om vi till exempel hade haft smutsig tvätt och enbart hade använt vatten vid rengöringen. När vi använder vat4-Bromo-3-methylaniline was used as the starting block to synthesise a Tröger’s base analogue with the aim of fusing the final monomer into a nanotube. The intermediates were to be characterised using 1H-NMR, 13C-NMR, infrared-, high resolution mass spectrometry, elemental analysis, and X-ray crystallography amongst other. At the end, 356 mg of N-((5R,6S,11R,12S)-8-amino-6,12-bis(methoxymethyl)-1,
Uppsatsens titel: Rapportering av intellektuellt kapital i Sydafrika - från företagens och investerarnas perspektiv; en kvantitativ studie i en tillväxtekonomi Seminariedatum: 2018-06-01 Kurs: FEKH69, Examensarbete i redovisning på kandidatnivå, 15 hp Författare: Hanna Rydholm, Josefine Ringnér och Carl De Geer Handledare: Kristina Artsberg Nyckelord: Intellektuellt kapital, Investerare, Humankapi
With the publication of the IPCC Special Report on Carbon dioxide Capture and Storage (CCS), CCS has emerged as a focal issue in international climate diplomacy and energy collaboration. This paper has two goals. The first goal is to map CCS activities in and among various types of intergovernmental organisations; the second goal is to apply International Relations (IR) theories to explain the gro
The interfacial structure of natural rubber (NR) colloids is investigated by means of cryogenic transmission electron microscopy (cryo-TEM) and electrokinetics over a broad range of KNO3 electrolyte concentrations (4-300 mM) and pH values (1-8). The asymptotic plateau value reached by NR electrophoretic mobility (mu) in the thin double layer limit supports the presence of a soft (ion- and water-pe
A small-scale combustor was set up to analyze the combustion of natural gas and two mixtures of partially reformed natural gas. The partially reformed mixtures can be formed using biomass to feed the endothermic reforming reactions. Before combusting these mixtures in a gas turbine, experimental work was done on a primary zone combustion chamber to examine the combustor behavior when switching fro

Syftet med studein är att studera Coding Technologies och hur det som litet företag har etablerat en högteknologisk standard på en marknad dominerad av stora aktörer. Resultatet av detta ska vara att identifiera viktiga faktorer och visa på strategier ett litet företag kan använda i denna situation. Studien är genomförd i form av en fallstudie med djupintervjuer där den teoretiska referensramen ar
Denna uppsats belyser hur svenska och indiska hotellföretag arbetar med mångfald samt vad som påverkar viljan till att främja mångfald på arbetsplatsen.
Plastics are versatile, cheap and durable materials that are omnipresent in modern society. Since most of them are derived from crude oil and are not biodegradable, their production leads to the depletion of fossil fuels and the accumulation of enormous amounts of plastic waste that pollutes ecosystems worldwide. For this reason, the European Union and other organisations are investing in research
Nuklearmedicinsk bildtagning med hjälp av radiofarmaka är ett viktigt verktyg för att studera biologiska processer och humansjukdomar. Bildtagning sker ofta med en detektor i kombination med en kollimator. En typ av kollimering är pinnhålskollimering, där ett pinnhål i ett opakt material placeras mellan en källa och en detektor. Pinnhålet fyller samma funktion som en optisk lins då emitterade fotoThe focus of this dissertation is the use of pinhole collimation in Nuclear Medicine. A pinhole is a single aperture in an opaque material that is placed between the detector and source of interest, and photons must pass through the hole to reach the detector. The choices of pinhole parameters, e.g. the pinhole material and size of the opening, are closely linked to the performance of the detector
Silicon isotope ratios (expressed as δ30Si) in marine microfossils can provide insights into silica cycling over geologic time. Here we used δ30Si of sponge spicules and radiolarian tests from the Paleogene Equatorial Transect (Ocean Drilling Program Leg 199) spanning the Eocene and Oligocene (~50-23 Ma) to reconstruct dissolved silica (DSi) concentrations in deep waters and to examine upper ocean
