I investigated the bacterial utilization of terrestrially derived dissolved organic nitrogen (DON) in aquatic ecosystems, and assessed the potential role of river-born DON in marine eutrophication. To determine the bioavailability of DON, I developed a bioassay employing N-limited bacterial regrowth cultures, which were calibrated with additions of inorganic nitrogen. I found that between 2 and 72
In this paper, we deal with the problem of exploiting baseline diversity of a multichannel interferometric SAR system to overcome the layover problem. The problem arises when different height contributions collapse in the same range-azimuth resolution cell, due to the presence of strong terrain slopes or discontinuities in the sensed scene. The multilook framework is adopted to counteract the pres
Popular Abstract in Swedish POPULÄRVETENSKAPLIG SAMMANFATTNING PÅ SVENSKA Neuroblastom är en barntumör i nervsystemet som drabbar ungefär 14 barn i Sverige varje år. Neuroblastom uppstår under bildandet av det sympatiska nervsystemet, som är den del av nervsystemet som ansvarar för vår reaktion på fara och stress. Det sympatiska nervsystemet bildas under fosterutvecklingen och de första åren efteNeuroblastoma is a pediatric tumor derived from cells in the sympathetic nervous system. In an attempt to explain the heterogeneous clinical behavior of neuroblastoma tumors, neuroblastomas have been characterized with regard to their degree of sympathetic differentiation. Their expression of genes and proteins that regulate normal sympathetic development and cell cycle/cell death regulators was a
In this study, a three-dimensional calculation method has been developed to simulate and analyze steam reforming of natural gas, and the effects on various transport processes in a duct from a compact steam reformer. The reformer conditions such as the combined thermal boundary conditions on solid walls, mass balances associated with the reforming reactions and gas permeation to/from the porous ca
Circuit complexity has been used as a tool to study various properties in condensed matter systems, in particular as a way to probe the phase diagram. However, compared with measures based on entanglement, complexity has been found lacking. We show that when imposing penalty factors punishing nonlocality, it becomes a much stronger probe of the phase diagram, able to probe more subtle features. We
Pixel classification of mixed pixels in overlapping regions of remote sensing images is a very challenging task. Efficiency and detection of uncertainty are always the key ingredients for this task. This paper proposes an approach for pixel classification using Shannon's entropy-based fuzzy distance norm. Unsupervised clustering is used to group the objects based on some similarity or dissimilarit
Background: For most companies that handle large material flows there are buffers between different stages in the supply chain, often referred to as inventory. The main reasons for having these inventories are to achieve economies of scale when handling material flows and to buffer against uncertainties when matching demand and supply. Hence, the main objective in inventory control is to decide
This thesis concludes that financially distressed targets’ shareholders gain significantly higher premiums. Acquirers’ shareholders suffer from value destruction in the short-run when acquiring distressed targets, whereas in the long-run value is created. However, both findings are insignificantly different from non-distressed M&As. Key long-term value drivers in distressed M&As are relati
Focusing on mounting challenges to agro-industrial capitals posed by emerging infectious diseases, this paper revisits longstanding debates in critical agrarian studies scrutinizing the role of turnover time. Analyzing Norway and Denmark's poultry industries' recent confrontations with avian influenza, and by paying close attention to the questions of temporality and disaggregating the agency of c
Resolutioner är per definition icke-bindande rekommendationer, men anses i vissa fall kunna få ett normativt värde, genom att bli relevant för påvisandet av en sedvanerättslig regels existens eller begynnande opinio juris. Faktorer som blir betydelsefulla för om en resolution ska anses få en sådan funktion är bland annat graden av stöd och upprepningen av resolutioner som ger uttryck för en regel.Resolutions are, by definition, non-binding recommendations, but are consi- dered in some cases to have a normative value, by becoming relevant for ascertaining the existence of a customary rule of international law or deve- loping opinion juris. Factors for determining whether a resolution has such a function includes the degree of support and repetition of the resolutions ex- pressing the rule.
Okawangodeltat är södra Afrikas största våtmark och en av världens minst påverkade våtmarker. Kunskapen om hur våtmarkssystemet fungerar är begränsad, särskilt vad gäller halter av näringsämnen och omsättning av näringsämnen i de dominerande våtmarksväxterna. I den här studien presenteras analyser av kol- , kväve- och kiselhalter i Cyperus papyrus som är den dominerande akvatiska växten i stora deThe Okavango Delta is southern Africa’s greatest wetland and is among one of the most pristine wetlands in the world. There is moderate information about how this system functions, however, the research on nutrient concentrations and cycles is especially limited. This study provides new knowledge on the Okavango Delta by analysing samples of Cyperus papyrus, one of the main aquatic plants in the a
För att möta behovet av en åldrande befolkning måste den svenska vården förändras, effektiviseras och struktureras om. Den svenska sjukvården måste flytta närmare patienten och därmed kommer hemsjukvården att bli allt viktigare. Hemsjuksköterskan har en samordnande och viktig roll inom hemsjukvården. Syftet med examensarbetet var att undersöka kommunikationen, informationsflödet och olika digitalaTo meet the needs caused by an aging population, Swedish healthcare must change to become more efficient. The healthcare system needs to be reconstructed, and the care needs to shift to become more patient centered. Therefore, home healthcare will become increasingly important. The homecare nurse has a coordinating, and therefore an important, role in home care. The purpose of this master thesis w
This essay is an analysis of the horse during the scandinavian bronze age, more specifically southern scandinavia with a breaking point at circa Gothenburg. The questions regard whether or not the horse was a high status animal during older to younger bronze age in the region and whether or not we can argue this based on rock carvings, horse gear and other pictorial renderings where the horse is p
Rätten att få myndighetsbeslut överprövade av domstol är begränsad. I förvaltningslagen (1986:223) saknas regler för vilka beslut som är överklagbara. Överklagbarhet kan följa av olika specialförfattningar eller förordningar, av allmänna förvaltningsrättsliga principer, av artikel 6.1 Europakonventionen eller av EU-rätten. Många av de förordningar som reglerar förutsättningarna för att bevilja s
The purpose of this thesis is to estimate the parameters in a stochastic volatility model in order to hedge derivatives based on underlying assets under the real probabilities as opposed to the standard method of esti- mating them under the risk neutral probabilities. We choose a common and reasonable but not to complex model of stock prices and other traded nancial assets, the Heston model, as we
