In Iceland every third individual is diagnosed with malignant disease; cancer being the cause of death in one out of four individuals with only cardiovascular diseases being more common cause of death. Approximately one third of cancer patients are diagnosed with lung metastases making the lungs one of the most common metastatic site. In some of these patients a metastasectomy is a treatment optio

Acute pancreatitis : a prospective study on incidence, etiology, and outcome

BACKGROUND AND AIMS: Prospective and population-based studies on the incidence of acute pancreatitis (AP) are lacking. Alcohol consumption has increased considerably in Iceland during the last decade. We aimed to determine the incidence, etiology, severity, and complications of AP and compare the results with a previous study on AP in Iceland.METHODS: A prospective population-based study of patien

INTRODUCTION: Information about the education, training and future employment prospects of Icelandic surgeons has not been available.MATERIALS AND METHODS: The study included all Icelandic surgeons, in all subspecialties, educated at the Faculty of Medicine at the University of Iceland. Information on specialty training, higher academic degrees and in which country these were obtained was collecte

Metastasis therapies for renal cancer

Purpose of review Although novel targeted therapies for metastatic renal cell carcinoma (RCC) are emerging, metastasectomy still remains the only potentially curable intervention and plays an important role both in disease control, cancer-specific survival (CSS) and overall survival (OS). A systematic review was conducted in 2014 by the European Association of Urology RCC guidelines panel to summa

Adenocarcinoma of the appendix with a fistula to the urinary bladder

Adenocarcinoma of the vermiform appendix is a rare disease that constitutes less than 0.5% of all gastrointestinal malignancies. A patient was admitted with abdominal discomfort and urinary frequency but no symptoms suggestive of enterovesical fistula, e.g. pneumaturia or urinary tract infection. She was diagnosed with adenocarcinoma of the appendix with a fistula to the urinary bladder.

OBJECTIVE: Adenocarcinoma of the appendix is less than 0.5% of all gastrointestinal cancers. The aim of this study was to analyse the incidence, symptoms, pathology and treatment of appendiceal adenocarcinoma in a well defined cohort as well as the prognosis of the patients.MATERIALS AND METHODS: This is a retrospective study on all patients diagnosed with adenocarcinoma of the appendix in Iceland

Early Complications After Percutaneous Closure of Atrial Septal Defect in Infants with Procedural Weight Less than 15 kg

Atrial septal defect (ASD) is the most common congenital cardiac lesion accounting for 10-15% of all cardiac malformations. In the majority of cases, the secundum type of the ASD is closed percutaneously in the catheterization laboratory. Although transcatheter closure of ASD is considered safe and effective in pediatric patients, there are limited data regarding the efficacy and safety of device

Analysis of flow dynamics and flame stabilization in gas turbine related combustors

The regulations on the emissions from combustion devices are getting more and more strict for environmental and human health reasons. Modern combustion research faces two major challenges; reduction of the pollutants, such as CO, NOx and unburnt hydro- carbons and increase of the combustion efficiency. Current trend for stationary power generation is to use lean premixed and/or pre-vaporized combu

Getting Tough on Unemployment : Essays on the politics of unemployment benefit reform in affluent democracies

The advanced democracies of Europe, North America, and Australasia have gotten tough on unemployment. Since the mid- to late-1970s, they started to put greater pressure on the unemployed by reducing the time for which unemployment benefits were paid, by imposing stricter job-search requirements, by extending the range of jobs considered suitable for claimants, and by tightening the penalties for n

On the Convergence of Iterative Learning Control

We derive frequency-domain criteria for the convergence of linear iterative learning control (ILC) on finite-time intervals that are less restrictive than existing ones in the literature. In particular, the former can be used to establish the convergence of ILC in certain cases where the latter are violated. The results cover ILC with non-causal filters and provide insights into the transient beha

Pappersarbete : Formandet av och föreställningar om kontorspapper som medium

This thesis explores office paper as a medium between 1920 and 1960 in Sweden. During this period, paper was muchdebated due to the number of standards that were implemented. These standardstransformed paper, making it a modern medium in many different ways. The aim ofthe present thesis is to analyze how office paper was reshaped to solveproblems regarding production, reproduction, circulation and

Effect of hydrophobically modified graphene oxide on the properties of poly(3-hydroxybutyrate-co-4-hydroxybutyrate)

Nanocomposites of poly(3-hydroxybutyrate-co-4-hydroxybutyrate) [P(3,4HB)] and hydrophobically modified graphene oxide (GO) were prepared via melt blending and characterised with respect to processability, polymer degradation, as well as thermal, rheological and mechanical properties. GO prepared via the modified Hummer’s method was alkylated by reactions with butyl-, octyl- and hexadecylamine, res

3D Rectangulations and Geometric Matrix Multiplication

The problem of partitioning an orthogonal polyhedron P into a minimum number of 3D rectangles is known to be NP-hard. In this paper, we first develop a 4-approximation algorithm for the special case of the problem in which P is a 3D histogram. It runs in O(mlogm) time, where m is the number of corners in P. We then apply it to exactly compute the arithmetic matrix product of two n×n matrices A and

Modelling and experiments of glassy polymers using biaxial loading and digital image correlation

Experimental data are needed to evaluate constitutive models. The richer the experimental data, in terms of different deformation modes for example, the better the constraints on the model. To this end, the mechanical response of glassy polycarbonate (PC) is studied using biaxial tension experiments with novel sample geometries. Deformation fields are measured using full-field digital image correl
