The inverse spectral problem for Schrödinger operators on finite compact metric graphs is investigated. The relations between the spectral asymptotics and geometric properties of the underlying graph are studied. It is proven that the Euler characteristic of the graph can be calculated from the spectrum of the Schrödinger operator in the case of essentially bounded real potentials and standard bou
We theoretically investigate electronic transport through a junction where a quantum dot (QD) is tunnel coupled on both sides to semiconductor nanowires with strong spin-orbit interaction and proximity-induced superconductivity. The results are presented as stability diagrams, i.e., the differential conductance as a function of the bias voltage applied across the junction and the gate voltage used
One of the specific predictions of a new strongly coupled dynamics at a TeV scale is the existence of stable vector-like technibaryon states so that the lightest neutral one could serve as a Dark Matter candidate. We study the latter hypothesis in the QCD-type technicolor with SU (3)(TC) confined group and one SU (2)(W) doublet of vector-like techniquarks consistent with electroweak precision cons
In this thesis, the main male characters in three of the plays written by Federico García Lorca are analysed with the aim of seeing the role they play in the frustration of desire. After two chapters dedicated to a review of published critical studies on Lorca and to certain theoretical considerations, Chapter Three examines desire drawing on Ubersfeld's actancial model and observes that these mal
How can revealing the past at historic sites benefit our society? This question has been discussed recurrently over the years within heritage studies and heritage practices; the suggested answers are many. This text analyses what has been remembered and forgotten in an urban development process, when the previously industrial area of Lomma Eternit in south Sweden was turned into a luxury residenti
A spinel-type catalyst of the composition Fe(2.50(1-z/3))V(0.20(1-z/3))Mo(0.30(1-z/3))square(z)O(4), where z is the number of cation vacancies (El), was prepared under reducing atmosphere. From the reduced sample a number of preoxidized samples were made by TPO treatment of the reduced material to different end temperatures ranging from 150 to 450 degrees C. XRD shows that the spinel-type structur
The generation of mathematical models of biological processes, the simulation of these processes under different conditions, and the comparison and integration of multiple data sets are explicit goals of systems biology that require the knowledge of the absolute quantity of the system's components. To date, systematic estimates of cellular protein concentrations have been exceptionally scarce. Her
Slutrapport för projektet Järnet och riksbildningen 1150-1350 (Jernkontort). I uppsatsen diskuteras konsumtion av järn i Bergen och Lödöse baserad på arkeologiskt material. Med utgångspunkt från resultaten görs bl a försök att hypotetiskt bestämma omfattningen av järn totalt i de äldre medeltida städerna i Sverige.
Cupriavidus necator H16 (formerly known as Hydrogenomonas eutropha) was famous as a potential single cell protein (SCP) in the 1970s. The drawback however was the undesirably efficient accumulation of non-nutritive polyhydroxybutyrate (PHB) storage compound in the cytoplasm of this bacterium. Eventually, competition from soy-based protein resulted in SCP not receiving much attention. Nevertheless,
Excited state dynamics and electron transfer from the Ru(dcbpy)(2)(NCS)(2) (RuN3) sensitizer to semiconductor nanoparticles were studied using time-resolved femtosecond absorption spectroscopy. We found that excitation of the red wing of the absorption spectrum of the sensitizer populates the (MLCT)-M-3 state directly, both in solution and attached on semiconductor nanoparticle films. Electron inj
Colorectal cancer (CRC) is a complex disease, and therefore its development is determined by the combination of both environmental factors and genetic variants. Although genome-wide association studies (GWAS) of SNP variation have conveniently identified 20 genetic variants so far, a significant proportion of the observed heritability is yet to be explained. Common copy-number variants (CNVs) are
To date there is no International standard on the verification and validation (V&V) of building fire evacuation models, i.e., model testers adopt inconsistent procedures or tests designed for other model uses. For instance, the tests presented within the MSC/Circ.1238 Guidelines for evacuation analysis for new and existing passenger ships provided by the International Maritime Organization are
BACKGROUND: The aim of the study was to examine associations between intake of macronutrients and dietary fiber and incident ischemic cardiovascular disease (iCVD) in men and women. METHODS: We used data from 8,139 male and 12,535 female participants (aged 44-73 y) of the Swedish population-based Malmö Diet and Cancer cohort. The participants were without history of CVD and diabetes mellitus, and
Checklistor gör det lättare att göra rätt på akuten. Det är tanken bakom en webbplats som lanseras denna månad. Den kommer att innehålla förslag till checklistor om vilken information som bör inhämtas för bedömningen på akutmottagningen. All akutpersonal inbjuds delta i utvecklingsprojektet.Checklists make it easier for the emergency physician. This is the idea behind a website launched this month. The site will contain suggestions for checklists on what information which should be obtained for the assessment of the patient at the emergency department. All emergency staff are invited to participate in the development of the project.
