Heparan sulfate proteoglycans consist of a small family of proteins decorated with one or more covalently attached heparan sulfate glycosaminoglycan chains. These chains have intricate structural patterns based on the position of sulfate groups and uronic acid epimers, which dictate their ability to engage a large repertoire of heparan sulfate-binding proteins, including extracellular matrix prote
Denna uppsats inriktar sig på identitetskapande i ett konsumtionssamhälle. Med det konsumtionskulturteoretiska forskningsfältet som utgångspunkt, undersöker denna uppsats hur konsumtion utav Apples Mac-dator används i en identitetskapande process. Undersökningen är gjord med en kvalitativ metod i form utav djupgående intervjuer med Mac-användare. Teorin som ligger till grund för uppsatsen är från
This thesis derives the explicit form of the elements of the (1/2,1/2) representation of the Lorentz group, by actually performing a direct product of the chiral (1/2,0)- and (0,1/2)-representations. The Lorentz transformations of fourvectors are thereafter recovered from this direct-product representation, allowing the derivation of a transformation matrix between the fourvector- and direct produ
In 2013 Kenya implemented their devolution, which is the process of devolving political functions, fiscal resources and administrative responsibilities to sub-national units. The central reason behind this constitutional change was to address the chronic ethnic conflicts of Kenya. A part of the ethnic conflict in Kenya is the plague of corruption, where it has divided the people of Kenya, putting
Three different least-squares methods for processing time-series of satellite sensor data are presented. The first method uses local polynomial functions and can be classified as an adaptive Savitzky-Golay filter. The other two methods are more clear cut least-squares methods, where data are fit to a basis of harmonic functions and asymmetric Gaussian functions, respectively. The methods incorpora
This thesis aimed to examine the relationship between climate and atmospheric CO2 concentrations through rapid climate changes during the Holocene. Climate was reconstructed using high-resolution, radiocarbon dated, lake sediment geochemical proxies (magnetic susceptibility, loss-on-ignition, total carbon/nitrogen/sulphur determinations and biogenic silica), vegetational reconstruction (pollen ana
The Extracting Syringe (ESy), a novel membrane-based sample preparation technique directly coupled as an autosampler to gas chromatography, has been employed for the analysis of organochlorine pesticides (OCPs) in raw leachate water. The ESy has also been applied for extraction of OCPs from contaminated soil samples and its performance has been compared to liquid-solid extraction (LSE) and acceler
Energy dispersive extended X-ray absorption fine structure (EDE) has been applied to Pd nanoparticle nucleation at a liquid/liquid interface under control over the interfacial potential and thereby the driving force for nucleation. Preliminary analysis focusing on Pd K edge-step height determination shows that under supersaturated conditions the concentration of Pd near the interface fluctuate ove
A piece of Helsingborg – about the moving of older buildings from the town and the making of an urban area at the Fredriksdal open-air museum The article tells the different stories of how fifteen houses, which during a period from the late 1930s until the 1960s, were moved from the town centre to the open-air museum at Fredriksdal, a part of the municipality museum. It depicts the struggle betwee
The problem of the orbital stabilization of the forced periodic motions of a non-linear all-wheel drive mechanical system is considered within the framework of a model that is widely used in problems of the planning of the motions and feedback design for industrial robotic manipulators. The basic result is the explicit indication of one of the possible redundant sets of coordinates tranverse to th
Background: Symptomatic osteoarthritis of the basal joint of the thumb (trapeziometacarpal joint) is a common disabling condition mainly affecting women. It is frequently treated with complete removal of the trapezium with or without soft-tissue interposition. There is limited evidence about whether removal of the trapezium affects stability of the wrist joint and increases the risk of developing
We formulate probabilistic numerical approximations to solutions of ordinary differential equations (ODEs) as problems in Gaussian process (GP) regression with nonlinear measurement functions. This is achieved by defining the measurement sequence to consist of the observations of the difference between the derivative of the GP and the vector field evaluated at the GP—which are all identically zero
