Kármán vortex streets are repeating patterns of swirling vortices, appearing when a fluid passes an obstacle at Re>50. We present an array of interacting vortices, a Kármán vortex city, that arises when a DNA solution flows through an array of micro posts at Re <0.5. Above thresholds in concentration and flow rate, the vortices formed behind posts interact, leading to concentration fluctuation wav

The physicochemical properties of two root suspensions, parsnip (Pastinaca sativa) and yacon (Smallanthus sonchifolius), were studied and compared at different concentrations and after being subjected to processes such as homogenization and heating. The study and the evaluation of the physicochemical properties of these plant materials in the form of pastes might help to increase the interest in t

In this work we present theoretical modeling and additional experiments to characterize noncontact acoustic trapping in a small glass capillary. We provide numerical 3D-simulations that captures several key features of the experiment.

We live in a time of wireless technologies, robotics and small computers with very high computing power. This is mainly due to a large emphasis given towards the study of semiconductor materials which are the building blocks of today's electronic industry. One of the secrets behind creating faster computers is the ability to integrate more and more transistors on a small semiconductor chip. GordonThis thesis studies the role of interaction between charged particles for transport and optical properties in nanostructures. Simulations are provided for a quantitative description of the system dynamics probed by either current spectroscopy or light absorption. In the first part of the thesis (Part I) the basic theories are described and in the second part of the thesis (Part II) the papers lis

Popular Abstract in English The ultimate goal of computer vision is to make computers "see" like humans do. Toward this goal, one essential step is to enable computers to perceive a three-dimensional (3D) space as in the real world. In this thesis, we investigate the problem of reconstructing a 3D scene model from ordinary two-dimensional (2D) images. More specifically, given a set of images of thThis thesis is focused on geometric computer vision problems. The first part of the thesis aims at solving one fundamental problem, namely low-rank matrix factorization. We provide several novel insights into the problem. In brief, we characterize, generate, parametrize and solve the minimal problems associated with low-rank matrix factorization. Beyond that, we give several new algorithms based o

This thesis consider the improvement of the simulation tools used to describe high energy particle collisions. These simulation programs are normally referred to as event generators. The emphasis is on two specific parts of the event generation: the introduction of radiation of weak bosons associated with the collision and a new model for colour reconnection. Each collision contains significant

Popular Abstract in English Does subjectivism in value theory — the view that value is grounded on attitudes — imply that when we think and talk about what is good and bad we must necessarily be thinking and talking about our desires and other attitudes? Does value subjectivism entail that evaluative utterances are reports or expressions of the speaker’s attitude? Are subjectivists committed to anThe thesis examines a specific way of understanding the subjectivist position in value theory according to which subjectivism is the view that value is grounded on attitudes. It is argued that this should be seen as a second-order claim about the nature of value although with pluralistic implications on the substantial, first-order level. Subjectivist analyses of final and intrinsic value and of r

Aim: To investigate the fees charged by Swedish dentists for root fillings, coronal restorations and further dental interventions during a follow-up period of 5–6 years. Methodology: A total of 248 299 root fillings were linked with the tooth, the patient and the provider and entered into the Swedish Social Insurance Agency register in 2009. The data register also recorded the subsidy-based (sched

Parkinson’s Disease (PD) is the most prevalent neurodegenerative movement disorder. Despite investigative efforts into the pathogenesis of the disease, the aetiology and mechanism of PD remains unknown, with multiple factors and cellular pathways known to play a part. But the genetic component of the disease, as well as enhanced vulnerability of the midbrain dopaminergic neurons of the Substantia

ATLAS measurements of two-particle correlations are presented for s=5.02 and 13 TeV pp collisions and for sNN=5.02 TeV p+Pb collisions at the LHC. The correlation functions are measured as a function of relative azimuthal angle Δφ, and pseudorapidity separation Δη, using charged particles detected within the pseudorapidity interval |η|2, is studied using a template fitting procedure to remove a "b

Background: Preeclampsia (PE) is a complex pregnancy syndrome characterised by maternal hypertension and organ damage after 20 weeks of gestation and is associated with an increased risk of cardiovascular disease later in life. Extracellular haemoglobin (Hb) and its metabolites heme and iron are highly toxic molecules and several defence mechanisms have evolved to protect the tissue. Objectives: W

We present a microfluidic device that can sort nanosized extracellular vesicles (EVs) based on electrokinetics and Deterministic Lateral Displacement (DLD). The device is made from PDMS using standard soft-lithography, can separate particles down to 200 nm, and what is more, can achieve almost two orders of magnitude higher throughput than an otherwise single electrokinetic DLD device.

Background: ECG changes after revascularization predicts improved outcome for patients with ST-elevation myocardial infarction (STEMI). Worst lead residual (WLR) ST deviation and resolution of worst lead ST elevation (rST elevation) are simple measures that can be obtained early after PCI. The objective of the current study was to investigate whether simple ECG measures, obtained one hour followin

The European Association of Urology (EAU) Renal Cell Carcinoma (RCC) Guideline Panel performed a protocol-driven systematic review (SR) on thermal ablation (TA) compared with partial nephrectomy (PN) for T1N0M0 renal masses, in order to provide evidence to support its recommendations. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed, and only

Scholarship on media and politics presumes a ‘mediatization’ of politics over time, which overlooks the evolution of a mediatized public sphere that shaped people’s understandings of what actually constituted politics. This article investigates the public sphere to demonstrate how it created expectations for politicians and journalists within the process of the mediatization of politics. To unders

Background: Although used extensively worldwide, the effects of general anaesthesia on the human brain remain largely elusive. Moreover, general anaesthesia may contribute to serious conditions or adverse events such as postoperative cognitive dysfunction and delirium. To understand the basic mechanisms of general anaesthesia, this project aims to study and compare possible de novo neuroplastic ch
