The dynamical theory of X-ray spectra due to Nozieres and De Dominicis (ND, 1969) is evaluated here numerically for numerous model systems including cases where the core-hole potential possesses a bound state. It is shown that the resulting emission spectra obey the final-state rule rather accurately. An approximate but analytical derivation of this rule is given which provides insight into the me
BACKGROUND AND PURPOSE: There are rising concerns about the frequency of infection after arthroplasty surgery. Prophylactic antibiotics are an important part of the preventive measures. As their effect is related to the timing of administration, it is important to follow how the routines with preoperative prophylactic antibiotics are working. METHODS: In 114 consecutive cases treated at our own un
Popular Abstract in Swedish Avhandlingen, som består av tre delar, handlar om olika metoder för att undersöka algebraiska begrepp med hjälp av datorberäkningar. I första delen visar vi att en viss Liealgebra inte, till skillnad från många andra Liealgebror av liknande typ, kan brytas ned i vinkelräta komponenter av en speciellt enkel typ. Andra delen handlar om vilka polynom som kan bildas genom
Proteoglycans (PG) are polyanionic proteins consisting of a core protein substituted with carbohydrate chains, that is, glycosaminoglycans (GAG). The biosynthesis of GAG can be manipulated by simple xylosides carrying hydrophobic aglycons, which can enter the cell and initiate the biosynthesis. While the importance of the aglycon is well investigated, there is far less information on the effect of
This paper presents an analysis of the point-spread functions (PSFs),which may be expected in the so-called improved seeing limited mode forthe Euro50 (Extremely large telescope with a 50 m aperture). This modecomprises adaptive control of the deformable secondary mirror of theaplanatic Gregorian telescope configuration using guide stars in a widefield. I may result in efficient compensation of tu
A number of matrix isolated binary hydrogen bonded complexes with water as one of the components have been investigated with FTIR in the mid and far infrared regions. Water has been found to be the hydrogen bond donor in complexes with water, ammonia, dimethyl ether and acetone. With formamide two equally strong hydrogen bonds are formed one from water to the carbonyl oxygen and one from an amide
The purpose of this work is to investigate if Miljöbyggnad certification works well for a building company in different regions of Sweden, or if a new or revised working method needs to be developed. To achieve the purpose, the author bases the study from a couple of interviews. The conclusion of the study showed that the Miljöbyggnad certification is rarely required at the Swedish building comp
Crime is a problem all over the world. We must sometimes look to other countries and legal systems to find solutions to our own problems. This the-sis will encompass the view into another system. Both the Swedish and Jap-anese perspective. In this thesis I present the reader with a comprehensive overview of the two justice systems, theories on crime, and restorative justice. An exploration of info
Abstract in UndeterminedThe separation of global radiation (Rg) into its direct (Rb) and diffuse constituents (Rg) is important when modeling plant photosynthesis because a high Rd:Rg ratio has been shown to enhance Gross Primary Production (GPP). To include this effect in vegetation models, the plant canopy must be separated into sunlit and shaded leaves. However, because such models are often to
Colloidal semiconductor nanocrystals, referred to as quantum dots, offer simple low-temperature solution-based methods for constructing optoelectronic devices such as light emitting diodes and solar cells. We review recent progress in the understanding of photoinduced processes in key components of a certain type of quantum dot solar cells where the dots sensitize a suitable metal oxide, such as Z
Onychophorans typically possess a pair of simple eyes, inherited from the last common ancestor of Panarthropoda (Onychophora + Tardigrada + Arthropoda). These visual organs are thought to be homologous to the arthropod median ocelli, whereas the compound eyes most likely evolved in the arthropod lineage. To gain insights into the ancestral function and evolution of the visual system in panarthropo
I en värld där klimathot och resursbrist har växt fram till ett allt större problem på världsledarnas agenda har vikten av hållbar utveckling identifierats som en nyckelfråga i vägen mot en bättre framtid. En metod för detta är industriell symbios, som innebär att olika företag och organisationer gemensamt utnyttjar energi, nyttigheter, material eller service, för att på ett innovativt sätt skapa In a world where climate change and resource scarcity have grown to some of the main issues on the world leaders’ agenda the importance of sustainable development has been identified as a key challenge in the path towards a better future. One method for this is industrial symbiosis, where different entities collaborate over energy, utilities, materials or services to create value and lower cost an
Satellites are key components in today's modern world, but they are expensive to launch and the orbits are crowded. With use of a dual band circular polarization selective structure (CPSS) the satellites can be improved and the number of reflectors needed to carry out a certain task can be reduced. A dual band CPSS reflects one handedness of circular polarization and transmits the other, over
Den engelska professorn och filosofen Roger Scruton har under ett långt akademiskt liv kritiserat samtiden på många olika sätt. Han är kritisk till det postmoderna samhället och filosofer som Focault, Derrida och Habermas. Han menar att den västerländska kulturen idag står under hot. Syftet med denna uppsats är därför att redogöra för och kritisk diskutera Scrutons analys och kritik av det västerlThe English professor and philosopher Roger Scruton has in a long academic life criticized contemporaries in many different ways. He is critical of the post-modern society and philosophers as Focault, Derrida and Habermas. He believes that Western culture today is under threat. The purpose of this bachelor's degree project is to describe and discuss critical Scrutons analysis and criticism of
ChemCo is a high quality producer in the speciality chemical market, a market characterised by complex production and high variability. With limited system-support and limited data quality, delivery accuracy suffered, and so did production efficiency. ChemCo believed that this was due to poor lead-time performance, why they wished to research the problem. Research on setting lead-times has focused
Vardagliga ting, så som detta papper, är sammanställt av vanlig materia. Det vi ser med våra ögon och genom teleskop när vi tittar upp mot stjärnorna är också sammanställt utav vanlig materia. Det visar sig att denna materia endast fyller vårt kända universum till 5 %. Resten kallas för Mörk Materia och Mörk Energi, där den föregående fyller universum med 27 % och den snarare till 68 %. Mörk MaterIn this thesis, I present a case where Dark Matter subhalos would annihilate at some stage in their lifetime. The implication of this scenario could potentially aid the Missing Satellites and the Cusp-Core density profile problem. The Dark Matter particles’ annihilation process and effective “friction” lead to an energy and momentum loss into radiation and hence to the destabilization of the Dark
Uppsatsen syftade till att skapa och testa ett enkelt verktyg att använda inom organisationer för att öka anställdas välbefinnande och förbättra upplevelsen av psykologiska, sociala och organisatoriska arbetsförhållanden. Med teoretisk utgångspunkt i positiv psykologi skapades en tre veckor lång arbetsplatsintervention. De 32 deltagarna var administrativ personal hos en politisk organisation indel
Milk is a complex liquid, which contains many different species, for example proteins, fat, minerals etc. It is the primary source of nutrition for young mammals before they are able to digest other types of food. The proteins can be divided into two groups: caseins and whey. Whey proteins are about 20 wt % of the total protein amount in milk, whereas the caseins corresponds 80 wt % of the total p
Purpose – Increasingly, last mile logistics is driven by customer-oriented strategies that requires better understanding of customers’ perceptions. This thesis views last-mile delivery as a service and aims to examine the relation of logistics service quality and other constructs used in service management literature to measure customers’ perception. Built on the operational definition of perceive
