The Lamperti transformation of a self-similar process is a stationary process. In particular, the fractional Brownian motion transforms to the second order stationary Gaussian process. This process is represented as a series of independent processes. The terms of this series are Ornstein-Uhlenbeck processes if H < 1/2, and linear combinations of two dependent Ornstein-Uhlenbeck processes whose two

This thesis is based on five studies. It includes the characterization of lipid micro emboli in shed mediastinal blood during cardiac surgery. The reuse of blood directly by cardiotomy suction is a common practice in order to reduce the need of blood transfusions. In shed mediastinal blood we showed that there is an abundance of lipid particles in the size range of 10-60μm. These lipid particles a

Even though the mammalian heart has been investigated for many years, there are still uncertainties in the fields of cardiac cell biology and regeneration with regard to exact fractions of cardiomyocytes (CMs) at different developmental stages, their plasticity after cardiac lesion and also their basal turnover rate. A main shortcoming is the accurate identification of CM and the demonstration of

The text-critical problem in the very beginning of the Gospel of Mark is both crucial and much debated. The main question is whether the phrase ‘Son of God’ was accidentally omitted from an original or added by some scribes in order to expand the divine name or the title of the book. The disputed words are enclosed in square brackets in UBS4 and NA27 but omitted in the recent SBLGNT edition. Where

Aim. The aim was to explore opinions on individual needs and other factors that may influence nursing staff turnover. Background. High staff turnover is a great problem for many hospitals. It is shown to have a negative effect on the quality of nursing care and to increase hospital costs. Design. In 2004 in a large university hospital in Sweden five focus group discussions (FGDs) including departm

A search for top quark pair resonances in final states containing at least one electron or muon has been performed with the ATLAS experiment at the CERN Large Hadron Collider. The search uses a data sample corresponding to an integrated luminosity of 2.05 fb(-1), which was recorded in 2011 at a proton-proton centre-of-mass energy of 7 TeV. No evidence for a resonance is found and limits are set on

Emissions of greenhouse gases in many European countries are declining, and the European Union (EU) believes it is on track in achieving emission reductions as agreed upon in the Kyoto Agreement and the EU's more ambitious post-Kyoto climate policy. However, a number of recent publications indicate that emission reductions may also have been achieved because production has been shifted to other co

We compare different preference restrictions that ensure the existence of a stable roommate matching. Some of these restrictions are generalized to allow for indifferences as well as incomplete preference lists, in the sense that an agent may prefer remaining single to matching with some agents. We also introduce a new type of cycles and in greater detail investigate the domain of preferences that

Infections frequently consist of more than one strain of a given pathogen. Experiments have shown that co-infecting strains often compete, so that the infection intensity of each strain in mixed infections is lower than in single strain infections. Such within-host competition can have important epidemiological and evolutionary consequences. However, the extent of competition has rarely been inves

Nonlamellar lipid liquid crystalline (LC) bulk phases and dispersions show promise as functional nanostructured materials for potential use as controlled release matrices e. g. in pharmaceuticals. Herein, methods for preparing and characterizing thin films of lipid liquid crystalline phases on solid surfaces are presented. The thickness, hydration phase structure and surface topography of spin-coa

Background - There are numbers of persons living in the community with late effects of polio, of which many develop new symptoms, but the course of progression is unclear. Objectives - To assess changes after 4 years in ability and perceived difficulty in persons with late effects of polio. Material and methods - Community dwelling persons from a polio clinic. Information was gathered by questionn

Web-based civic participation in democracies, especially in the sprawling domain of alternative politics, continues to grow. In this paper I explore the intersection of two trajectories of such participation: one that takes the form of journalism (broadly understood) and the other that is transnational in character. Participatory journalism unavoidably evokes normative issues that professional jou

Popular Abstract in English Each year an estimated 530 000 new cases of cervical cancer are diagnosed and more than 275 000 women die from cervical cancer worldwide (2). Cervical cancer is caused by sexually-acquired infections with a subset of human papillomavirus (HPV) (359, 360). HPV is the most common viral infection of the anogenital tract (2). Almost all sexually active individuals will be iHuman papillomaviruses (HPVs) cause almost half of the human cancers that are attributable to viruses. HPV type 16 is the most carcinogenic type among the HPVs and is detected in 50% of all cervical cancers. HPV-16 infects epithelial cells and HPV-16 gene expression is tightly linked to the differentiation stage of the infected cells. Early HPV-16 genes are expressed in basal layers of the epithel

Background: Acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) are common early-onset malignancies. Their causes are largely unknown but infectious etiology has been implicated. Type 1 diabetes (T1D) is an autoimmune disease for which infectious triggers of disease onset have been sought and increasing pointing to enteroviruses. Based on our previous results on co-morbidity betwee

Background/Aim: Matrix metalloproteinases (MMPs) are involved in cancer biology. Expression of MMP7 (matrilysin) in colorectal cancer is associated with metastatic disease even though it is expressed in most tumour states. In the present study, our purpose was to analyze MMP7 in bowel and lymph nodes of different tumour stages and to evaluate its expression as a cancer biomarker. Patients and Meth

Nectar-feeding insects find flowers by 2 means, innate preferences and learned associations. When insects that hibernate as imagos (i.e., adults) start foraging after a long winter break, what guides them to new nectar rewards? Are innate preferences kept over such a long period? And are learned associations useful after long breaks? In a series of experiments I show here that, depending on previo
