The neutral vacancy in Ge has been studied using a Green function method which is particularly well suited to point defects with highly localised bound-state wavefunctions.(16 refs)

The wireless propagation channel significantly influences the received signal, so that it needs to be modeled effectively. Extensive measurements and analysis are required for investigating the validity of theoretical models and postulating new models based on measurements. Such measurements, analysis, and modeling are the topic of this thesis. The focus of the included contributions are Multiple-

The operative treatment of mallet fractures of more than one third of the articular surface is controversial. The purpose of this study was to evaluate the complications and functional outcome of extension block pinning technique. Thirty-six consecutive patients with mallet fractures that involved more than one third of the joint surface were treated by extension block pinning a median of 3 days a

To address a diversified student complement in academic studies is becoming more and more frequent in maritime education and training. Diversity challenges are also the reality onboard ships that muster a multicultural crew complement. This thesis aims at creating awareness on dilemmas and challenges that students and faculty meet when working in a multicultural environment. In order not to have

Nissen fundoplication is an effective treatment for gastroesophageal reflux disease (GERD) but can cause adverse effects like flatulence and dysphagia. The aim was to compare laparoscopic anterior 120° fundoplication (APF) to total fundoplication (Nissen) concerning flatulence and other adverse effects, in a randomized blinded study.

We construct finite-dimensional representations of the quantum affine algebra associated to the simple finite-dimensional Lie algebra sl(n+1). The module structure is defined on the vector space tensor product of the fundamental representations of the quantum affine algebra. To do this, we find a particular basis of every fundamental representation, consisting of eigenvectors for some of the Drinf

The study aims to establish the effectiveness of the Danish destination certification scheme – Destination 21. In order to accomplish this, an analytical framework, based upon current tourism and development theory, was constructed against which the scheme was tested. The analytical framework consists from three analyses examining the schemes framework, substance and applicability. It was found th

In this study, the upward (IUS) and downward (IDS) slopes of the QRS complex are proposed as indices for quantifying ischemia-induced electrocardiogram (ECG) changes. Using ECG recordings acquired before and during percutaneous transluminal coronary angioplasty (PTCA), it is found that the QRS slopes are considerably less steep during artery occlusion, in particular for IDS. With respect to ischem

BACKGROUND: Diabetic nephropathy, a major complication of diabetes, is characterized by progressive renal injury and increased cardiovascular mortality. An increased urinary albumin excretion due dysfunction of the glomerular barrier is an early sign of diabetic nephropathy. An increased urinary excretion of higher molecular weight proteins such as IgM appears with progression of glomerular injury
