In this thesis we extend several classical results about Calderón-Zygmund operators to spaces of vector-valued functions. We first obtain bounds for the norm of dyadic Haar shift operators using a Bellman function technique, and then apply the representation theorem to obtain corresponding results for general Calderón-Zygmund operators. We discuss several results for UMD space-valued Calderón-Zygm

In the search for viable pathways for transforming governance and institutions in the Rio+20 agenda, strengthening of public-private governance networks has been emphasized. Important initiatives are found in the expanding bioenergy sector where several certification schemes have been launched for ensuring that bioenergy feedstock meet environmental and social requirements. These initiatives are e

GRASP (Group and Social Psychology) is an interdisciplinary conference, which aims to provide a community around social psychological issues for researchers, practitioners, and graduate students from the Nordic countries within the fields of psychology, sociology, education, behavioural sciences and social work to share, exchange, learn, and develop preliminary results, new concepts, ideas, princi

Co-presentation with both ANCA and anti-GBM antibodies is thought to be relatively rare. Current studies of such 'double-positive' cases report small numbers and variable outcomes. To study this further we retrospectively analyzed clinical features and long-term outcomes of a large cohort of 568 contemporary patients with ANCA-associated vasculitis, 41 patients with anti-GBM disease, and 37 double

Myeloid cells play a central role in atherosclerosis. We investigated the associations between the plasma levels of growth factors and chemokines that regulate myeloid cell homeostasis and function and the risk of first-time acute coronary events in middle-aged persons. Methods and Results-We measured baseline plasma levels of macrophage colony-stimulating factor monocyte chemotactic protein 1; C-

The retina is a thin tissue layer on the inside of the eye and may be subject to tractional forces in diseases like myopia, retinoschisis, and retinal detachment. Müller glial cells (MGCs) are the only cells spanning the entire retinal thickness and hypothetically respond to mechanical stress imposed across retinal layers. We designed a device to apply force in vitro perpendicular to the retinal sThe retina is a thin tissue layer on the inside of the eye and may be subject to tractional forces in diseases like myopia, retinoschisis, and retinal detachment.

BACKGROUND. Understanding the genetic architecture of cardiac structure and function may help to prevent and treat heart disease. This investigation sought to identify common genetic variations associated with inter-individual variability in cardiac structure and function. METHODS. A GWAS meta-analysis of echocardiographic traits was performed, including 46,533 individuals from 30 studies (EchoGen

This report deals with the identification of ATP/ADP translocase genes. In rickettsial species such as Rickettsia prowazekii, which is the cause of epidemic typhus in humans, the utilisation of host cell ATP is the major way that this bacterium employ its toxicity in the host cell. This obligate intracellular bacterium is an energy-parasite. In the genome of R. prowazekii there are five homologs o

I det här arbetet har de neurotoxiska effekterna av paraquat och roundup studerats, efter en neonatal lågdos-exponering. Paraquat förekommer i miljön och dess likhet med det neurotoxiska ämnet l-methyl-4-phenyl-1,2,3,6-tetrahydropyridin (MPTP) gör den intressant i neurotoxikologiskt avseende. Detta arbete omfattar tre olika försök. I försök 1) exponerades möss neonatalt for paraquat, dessa djur av

Using a parsimonious, analytically tractable dynamic model, we are able to explain up to 100 years of the available data on the dynamics of top-wealth shares for several countries. We build a micro-founded model of heterogeneous agents in which - in addition to stochastic returns on investment - individuals disagree marginally on their expectations of future returns and thus hold different asset p

It is often claimed that the social sciences cannot be reduced to a lower-level individualistic science. The standard argument for this position (usually labelled explanatory holism) is the Fodorian multiple realizability argument. Its defenders endorse token-token(s) identities between “higher-level” social objects and pluralities/sums of “lower-level” individuals (a position traditionally called

In this paper, a control-oriented soot model was developed for real-time soot prediction and combustion condition optimization in a gasoline Partially Premixed Combustion (PPC) Engine. PPC is a promising combustion concept that achieves high efficiency, low soot and NOx emissions simultaneously. However, soot emissions were found to be significantly increased with high EGR and pilot injection, the

Objective: Oxygen enhanced pulmonary MRI is a promising modality for functional lung studies and has been applied to a wide range of pulmonary conditions. The purpose of this study was to characterize the oxygen enhancement effect in the lungs of healthy, never-smokers, in light of a previously established relationship between oxygen enhancement and diffusing capacity of carbon monoxide in the lun

Laser-induced photofragmentation fluorescence has been investigated for the imaging of alkali compounds in premixed laminar methane–air flames. An ArF excimer laser, providing pulses of wavelength 193 nm, was used to photodissociate KCl, KOH, and NaCl molecules in the post-flame region and fluorescence from the excited atomic alkali fragment was detected. Fluorescence emission spectra showed disti
