Reconstructing the vortex wake of freely flying birds is challenging, but in the past few years, direct measurements of the wake circulation have become available for a number of species. Streamwise circulation has been measured at different positions along the span of the birds, but no measurements have been performed in the transverse plane. Recent findings from studies of bat wakes have pointed
Researchers in the field of molecular ecology and evolution require versatile and low-cost genetic typing methods. The AFLP (amplified fragment length polymorphism) method was introduced 10 years ago and shows many features that fulfil these requirements. With good quality genomic DNA at hand, it is relatively easy to generate anonymous multilocus DNA profiles in most species and the start-up time
Random processes are generally described by Gaussian statistics as formulated by the central limit theorem. However, there exists a large number of exceptions to this rule that can be found in a variety of fields. Diffusion processes are often analyzed by the scaling law < r(2)>similar to t(2 beta), where the second moment of the diffusion propagator or molecular mean square displacement, < r(2)>,
Neuronal function depends on the properties of the synaptic inputs the neuron receive and on its intrinsic responsive properties. However, the conditions for synaptic integration and activation of intrinsic responses may to a large extent depend on the level of background synaptic input. In this respect, the deep cerebellar nuclear (DCN) neurons are of particular interest: they feature a massive b
Charged-particle production was studied in proton-proton collisions collected at the LHC with the ALICE detector at centre-of-mass energies 0.9 TeV and 2.36 TeV in the pseudorapidity range vertical bar eta vertical bar < 1.4. In the central region (vertical bar eta vertical bar < 0.5), at 0.9 TeV, we measure charged-particle pseudo-rapidity density dN(ch)/d eta = 3.02 +/- 0.01(stat.)(-0.05)(+0.08)
By international standards, children in Sweden experience good health. Sweden has low infant mortality rates, low accident mortality rates, a high number of breastfed children and a high proportion of vaccinated children. However, during the past twenty years the prevalence of overweight children has doubled in Sweden, while that of obese children has increased 4-5 times. Furthermore, there has be
Cysteine proteinases are important not only in the intracellular catabolism of peptides and proteins1 and in the processing of prohormones and proenzymes2,3, but also in the penetration of normal human tissue by malignant cells4 and possibly microorganisms5, including viruses. Cystatin C is a human cysteine proteinase inhibitor present in extracellular fluids6. We have synthesized peptide derivati
The Lund Botanical Society 2007-03-23 decided to launch a project with the following aims: 1) to map the frequency and distribution of all bryophytes in the province of Skåne, southernmost Sweden, thereby making way for future studies of changes in the flora, 2) to find and document as many sites as possible for nationally and regionally rare or endangered bryophytes and initiate conservation acti
The forces of globalization and the enabling characteristics of internet communication have impacted the nature of research and innovation. Knowledge and innovation processes are both more dispersed and more openly accessible. In addition, we witness a shift in the global knowledge and innovation geography with both being increasingly generated and developed in regions outside Europe, Nort
Populärvetenskaplig sammanfattning:Dagens datorer har krympt i storlek i takt med den ständigt ökande kompetensen att tillverka transistorer med en anmärkningsvärd noggrannhet. Storleksskalan av nya transistorer börjar motsvara den av en handfull atomer.På denna skala dominerar kvantfysik, vilket är ett väsentligt hinder för de traditionella datorkomponenterna. Men detta innebär inte bara en begräThe work contained in this thesis deals with two closely related topics. Papers I-III deal with charge transport statistics in nanoscale devices to investigate the presence of entanglement in the constituent electrons. We identify the contributions of entangled electron pairs to the current cross-correlations as a signature of entanglement. Paper IV treats the electric control of a quantum dot ba
We show two results related to finding trees and paths in graphs. First, we show that in $O^*(1.657^k2^{l/2})$ time one can either find a $k$-vertex tree with $l$ leaves in an $n$-vertex undirected graph or conclude that such a tree does not exist. Our solution can be applied as a subroutine to solve the $k$-Internal Spanning Tree problem in $O^*(min(3.455^k, 1.946^n))$ time using polynomial space
Osteoarthritis (OA) is the most common form of arthritis and often causes pain and functional impairment. Despite its high burden on society, knowledge about the occurrence of OA and its associated mortality is sparse. The epidemiology of OA is difficult to determine due to the patients’ fluctuating symptoms and challenges in detecting and defining the radiographic disease. The specific aims of th
High-resolution core-level photoemission is used to study structural aspects for the molecular adsorption of CO on the Rh(111) single-crystal surface, and in particular to derive the adsorption sites. The site sensitivity of the core-level binding energy and the fact that the core level photoemission signal is proportional to the adsorbate coverage make it possible to study quantitatively how the
Background: The autoimmune destruction of beta cells, resulting in clinical type 1 diabetes, may start early in life and last for several months or years. During this period of time, we have an opportunity to try to prevent or delay further beta-cell destruction and clinical onset of type 1 diabetes. Objectives: Ongoing prediction and prevention studies in Skåne, Sweden are described. Methods: Dur
Previous research has shown that the relationship between the news and parliament is complex and highly variable. Studies have found that in many countries, parliament has minimal influence on the news. However, in the UK, a reciprocal influence between parliament and the news was found, with the media having a stronger effect. This thesis investigates how the news and parliament affect each other
Purpose: The purpose of this thesis is to analyze the fossilization in language acquisition of Italian of two Swedish learners. I intend to use the Processability Theory and the Theory of gradual construction of italian verbs of the Pavia project. I also intend to investigate the sources of linguistic input of the learners . Methodology: I have recorded two learners as they speak and based on th
I denna uppsats undersöker jag problemet med bolagskapning och till viss del hur detta reflekterar det underliggande problemet med Bolagsverkets system för registrering av bolagsuppgifter med syfte att förstå problemet och identifiera lösningsmöjligheter inom gällande rätt samt nytillkomna lagändringar. För att förstå problemet med bolagskapning lyfter jag fram tidningsartiklar och statistiska undIn this essay, I examine the issue with the hijacking of corporations and, in part, how this reflects the underlying problem with the system for registration of corporation details of the Swedish Companies Registration Office, with the objective of understanding the issue and identifying possible solutions within the existing legislation as well as recently implemented changes of the legislation.
Uppsatsen syftar till att utreda de kriminalpolitiska skäl som ligger bakom den svenska och danska kriminaliseringen respektive icke-kriminaliseringen av köp av sexuella tjänster. Därutöver diskuteras huruvida dessa motiv är förenliga med kravet på att ett straffstadgande ska vara effektivt för att kriminaliseringen ska anses vara befogad. Utredningen grundar sig dels i en rättsdogmatisk, dels i eThe aim of this essay is to investigate the political reasons behind the Swedish criminalization and the Danish non-criminalization of the purchase of sexual services, and whether these purposes align with the requirement that a prohibition should be effective to be considered justified. The investigation is based on a legal doctrinal and comparative method combined with a critical, political, and
One way of meeting the increasing demand for higher data rates is by building denser cellular networks in order to maximize the use of the frequency spectrum. The denser deployment leads to an increased probability of inter-cell interference, the phenomenon where the signal quality experienced by a user served by a cell is lowered because of the transmission from neighboring cells in the network.
Att använda vaccinpass under covid-19-pandemin är omdiskuterat och frågan om förenligheten med mänskliga rättigheter lyfts ofta i debatten. Sedan den 1 december 2021 har Sverige gällande regler för när vaccinationsbevis kan krävas och det finns förslag som skulle innebära att användningen utökas. Den här uppsatsen syftar till att ta reda på hur den svenska regleringen kring vaccinpass ser ut och aThe use of vaccine passports during the covid-19-pandemic is a topic widely discussed and the question of its conformity with human rights is often lifted in the debate. Since the 1st December 2021, Sweden has regulations in place for when proof of vaccination can be required and there are drafts that would expand the use even more. This essay seeks to find out what the Swedish regulation concerni
