The cross section for the diffractive deep-inelastic scattering process ep -> eX(P) is measured, with the leading final state proton detected in the H1 Forward Proton Spectrometer. The data analysed cover the range x(P) < 0.1 in fractional proton longitudinal momentum loss, 0.08 < vertical bar t vertical bar < 0.5 GeV-2 in squared four-momentum transfer at the proton vertex, 2 < Q(2) < 50 GeV2 in
We present the first results from our survey of stellar substructure in the outskirts of M31 using the Advanced Camera for Surveys on board the Hubble Space Telescope. We discuss the stellar populations associated with five prominent stellar overdensities discovered during the course of our panoramic ground-based imaging survey with the Isaac Newton Telescope Wide-Field Camera; a sixth pointing ta
Vectoring is a vital component of wideband wire- line communication systems. A disorderly leaving event (DLE) disturbs the vectoring operation since the precoder, which was designed for the channel before the change, is no longer up to date. Measurements indicate that the impact of a DLE can be serious for frequencies beyond 30 MHz, which corresponds to the band used by emerging wideband communica
Aviation fuel is a petroleum product that fulfills the Standard Specification for Aviation Turbine Fuels. Crude oil has been the raw material for production of aviation fuels for many years. Since the availability of crude oil is predicted to be limited in the future, alternative raw materials for aviation fuels are highly desirable. A Swedish company, Oroboros AB, has developed a novel clean synt
The close relationship between motion (bodily movement) and emotion (feelings) is not an etymological coincidence. While moving ourselves, we move others; in observing others move - we are moved ourselves. The fundamentally interpersonal nature of mind and language has recently received due attention, but the key role of (e)motion in this context has remained something of a blind spot. The present
The development of electrical resistivity imaging techniques has been rapid in the last decade. This applies to data acquisition as well as inverse modelling techniques, and has lead to a greatly expanded practical applicability of the method. A trend today is to move from traditionally used electrode array types towards non-conventional arrays that are more efficient for multi-electrode equipment
Water-soluble hemicelluloses were extracted from spruce chips by heat-fractionation using microwave treatment. A screening of conditions (pH, temperature and residence time) was performed for the extraction of O-acetyl-galactoglucomannan (AcGGM). The yield and the average molecular weight of the extracted mannan were analysed using HPLC, size-exclusion chromatography (SEC) and mass-spectrometry. T
PURPOSE:: The purpose of this study was to characterize the phenotype of fundus albipunctatus associated with RDH5 mutations. METHODS:: Four unrelated patients (patients 1-4) aged 35, 32, 19, and 8 years were examined with full-field electroretinography, multifocal electroretinography, optical coherence tomography, and fundus autofluorescence photography. Molecular genetic investigations included
BACKGROUND: It is difficult to estimate the diagnostic accuracy of biopsy for prostate cancer because men with negative biopsy do not undergo radical prostatectomy and thus have no confirmation of biopsy findings. METHODS: We performed 18-core needle biopsies on autopsy prostates from 164 men who had no history of prostate cancer. Six-core biopsies were taken from each of the mid peripheral zone (
Terrestrial ecosystem models (TEMs) contain the coupling of many biogeochemical processes with a large number of parameters involved. In many cases those parameters are highly uncertain. In order to reduce those uncertainties, parameter estimation methods can be applied, which allow the model to be constrained against observations. We compare the performance and results of two such parameter estim
In this paper we present a model of the dissolved organic carbon (DOC) concentrations and fluxes in mire water based on the convection-dispersion equation. The dynamics of sorbed, potentially soluble organic carbon (SPSOC) in the peat matrix are simulated in parallel with DOC. First, the model is applied solely to stagnant water conditions in order to interpret the results of laboratory peat incub
The aim of this study is to reveal how the oil-in-water interface of triolein emulsions in aqueous solutions is affected by the lipase activity when using five different surfactants as emulsifiers. For this purpose Dynamic Light Scattering (DLS) and Small Angle X-ray Scattering (SAXS) were applied. Lipases are enzymes that catalyses the hydrolysis of ester bonds of lipids, i.e lipolysis, and act a
In order to improve companies' and public health organizations' abilities to forecast the future beverage market volumes, it is crucial to identify the determinants of beverage consumption. Based on the market volume panel data from 2005 to 2020, this thesis formulates a fixed-effect model to examine the causal relationship between the population share of young adults and the market volume
The city of Lund updates the handling plan of garden waste with the desire to use it for biogas production. Garden waste works best as biogas substrate when it is separated in two fractions. Today, however, there are no sorting of the residents’ garden waste. The aim of the thesis is to explore how private households can sort out a fraction of garden waste that can be used to produce biogas. First
In this report a study is made of a sandwich wall especially produced for agricultural buildings. The wall contains two concrete slabs, one for the façade and one on the inside with insulation between them. The concrete slabs are joined together by lattice girders. The inner slab has a thicker cross section in it’s ends and less insulation, the girders also has a smaller distance between them. The
ABSTRACT Calcareous sandy grasslands are among the most threatened habitats in Europe, primarily because of abandonment, acidification, eutrophication and fragmentation. Much of the biodiversity found in calcareous sandy grasslands depend on the availability of calcareous sand in the topsoil layer. As this sand is naturally depleted of CaCO3 heavy disturbances such as erosion or use of military
The aim of this study is to investigate how school counselors describe control over their work situation and to conclude which factors compicate and ease the counselors to feel in control. This study is empirically based on semi-structured interviews of seven school counselors. The conclusions indicates that the counselors generally though they had control over their work although there were uncle
Ämnesområdet riskhantering utvecklas ständigt i takt med att samhället blir alltmer komplext, vilket innebär att risker och sårbarheter är svåra att förutspå. Enligt svensk lagstiftning ska kommunerna analysera vilka potentiella extraordinära händelser som finns i kommunen, där risk- och sårbarhetsanalyser är en central beståndsdel i arbetet. Enligt Lagen om kommuners och landstings åtgärder införThe master thesis examines what evaluation methods that are available to evaluate RVA-work and analyze which of the methods that are best suited for Malmo. Thereafter two alternative evaluation methods will be presented. This will be based on the literature study of evaluation methods for RVA-work, interview study with Swedish municipalities about their RVA-work and a study of Malmo’s RVA-work for
The UAV (unmanned aerial vehicle) is a part of the digital transformation in the construction industry. With increased options of low-cost UAVs, more companies will want to integrate UAVs into their business. By capturing a large amount of data in a short time, it could be very useful for several applications within the construction industry. The question is: can the low-cost UAV be an option cons
In this thesis I study the performances of artificial neural networks (ANNs) and three various ARCH-type models to predict weekly volatility of the Swedish (OMXS30), the British (FTSE100) and the Australian (S&P/ASX200) major stock indices. The three various ARCH-type models are the GARCH(1,1), the EGARCH(1,1) and the TGARCH(1,1). The purpose is to investigate if ANNs outperform the more tradi
