A Fortran program for analysis of spectra obtained in proton induced x-ray emission spectroscopy is under development. The first version is working and some results are shown. The program uses a model which describes the physics involved in the analysis. The continuum is described by an exponentially decreasing function representing secondary electron induced bremsstrahlung and a constant approxim
In the last decades, the growing competitiveness of the market has continuously driven the forming companies to highly optimize their products regarding offered performance at minimum cost. In order to achieve better products, studies where conducted with different material models when simulating the forming process of titanium. The material is often used in heat exchanger applications. Titanium h
In this article we will discuss the basic calculational concepts to simulate particle physics events at high energy colliders. We will mainly focus on the physics in hadron colliders and particularly on the simulation of the perturbative parts, where we will in turn focus on the next-to-leading order QCD corrections.
Tänk dig att du har en tung elastiskt stång som hänger ner från ett fäste i taket och töjs ut, dels på grund av sin egentyngd och dels på grund av en extra tyngd som är fastsatt i botten av stången. Det skulle till exempel kunna vara ett rör som går från en oljerigg (taket) ner mot havets botten där en borr är fastsatt (tyngden). Vi kan styra hur mycket stången kommer töjas genom att justera tvärsWe study the problem first introduced by Verma and Keller in 1984 of how to taper a heavy rope such that its elongation is minimized. The problem is stated as an optimization problem of a functional J[w]. Specifically we provide a proof of optimality for the solution using traditional convex optimization techniques. We also utilize the Legendre transformation when studying the Euler–Lagrange equat
This study aims to research how honour is explained and defined by social workers and thus increase the knowledge about the concept itself, and the negative consequences it can have on an individuals’ life. By interviewing (both in a group interview, and in a one-on-one interview) professionals who daily are coming into contact with honour codes and context, and letting them give their view on the
Sustainability Science (SS) has, as of today, no explicit agreement on which philosophy of science should be used to guide its research. Though SS is a broad and often diffuse concept, there are certain guiding principles which are generally agreed on. Based on these principles, it has been seen if Critical Realism (CR) could be an appropriate meta-theory for SS. The approach used is therefore pri
Syftet med denna uppsats var att genom en explorativ fallstudie se vilka olika typer av konflikter som beskrivs av anställda på ett mindre företag (13 anställda) i södra Sverige. En kvalitativ, emergent design användes för studien. Samtliga medarbetare på företaget ingick i urvalet och fick svara helt fritt på en öppen fråga kring vilka spänningar, friktioner eller möjliga konflikter de upplever pThis essay examines how employees in a small company (13 employees) in southern Sweden describe their experiences of conflicts in their workplace. A qualitative emergent design was used, and participants were given an open question and were asked to complete a written answer to it. The material was analyzed through an intuitive phenomenological approach as well as through a lexicalical analysis in
Popular Abstract in Swedish Avhandlingen ”Tingens och tankarnas landskap” söker arkeologiska metoder och teorier för ett humanistiskt närmande av människans tidiga naturumgänge. Med arkeologiskt menas här fokuseringen på de materiella spåren i landskapet, stora som små, naturdanade som människotillverkade. Tidsperspektivet är i huvudsak långtida. I avhandlingen har jag valt ett ekologiskt perspektThe thesis "Tingens och tankarnas landskap" is about the material traces of man and his activities in the past. The study investigates the possibility and methods of describing man’s interaction with nature. Man’s relationship to the physical surroundings is viewed from cultural and social perspectives, using the materials of long-term archaeology. The study also includes a contemporary dimension.
Karyotype structures of Scenedesmus acuminatus (Lagerch.) Chod. and Scenedesmus pectinatus Meyen are compared. The karyotype of S. acuminatus (n = 5) is described for the first time. It reveals four large metacentric and one large submeta centric chromosomes (4M + 1SM). The established karyotype differences have been helpful in clarifying the taxonomic position of these two species. The cytologica
The aim was to examine tissue expression of Ku protein in lower lip salivary gland (LSG) biopsies from cases of primary Sjogren's syndrome (SS) and from normal subjects. Methods: immunohistochemistry was used with antibodies to Ku70/86 and also Ki67, PCNA and p53. In addition, the Klenow method was applied in order to detect evidence of apoptosis. Sections of hyperplastic tonsil served as addition
In osteoarthritis (OA), cartilage and bone fragments have been described within the synovial tissue which are surrounded by synovial cells (i.e. detritus synovitis). These cells appear to attach actively to the cartilage and bone fragments. In rheumatoid arthritis (RA), on the other hand, synovial fibroblasts (SF) have also been shown to be localized at sites of invasion into cartilage and bone an
Some of the compounds used for density gradient separation of blood cells have high osmolarities at the concentrations needed to create the required specific densities. Several mixed media use a combination of hyperosmolar shrinkage and red cell aggregation to improve cell separation. Due to the characteristics of Percoll density gradient medium the density and osmolarity of the gradient can be co
Genetic segregation analysis between NOD and C57BL strains have been used to identify loci associated with autoimmune disease. Only two loci (Cia2 and Cia9) had earlier been found to control development of arthritis, whereas none of the previously identified diabetes loci was of significance for arthritis. We have now made a high-powered analysis of a backcross of NOD genes on to the B10.Q strain
The emergence of post-genomic approaches that couple chromatin immunoprecipitation (ChIP) assays to high-throughput technique has greatly advanced our ability to investigate epigenetic features associated with normal cell development and disease. Nevertheless, these techniques exhibit some limitations. Firstly, standard protocols usually require millions of cells, thus limiting their application t
