Background Smokers have a substantially increased risk of postoperative complications. Preoperative smoking intervention may be effective in decreasing this incidence, and surgery may constitute a unique opportunity for smoking cessation interventions. Objectives The objectives of this review are to assess the effect of preoperative smoking intervention on smoking cessation at the time of surgery

Beads made from animal teeth were an important form ofdecoration among hunter-gatherer societies in Northern Europe.The analyses presented in this paper are based on questionsregarding the design of the beads, the choice of animal teeth,their placement on the costume, and the exchange of beads.

Popular Abstract in Swedish Denna avhandling behandlar en speciell typ av felrättande koder som kallas tailbitingkoder. Syftet med en felrättande kod är att korrigera fel som kan uppkomma på grund av brus och störningar då digital information överförs från sändare till mottagare.Tailbiting is a method to terminate convolutional codes into block codes. We call these block codes tailbiting codes. This thesis focuses on the encoding of tailbiting codes. The tailbiting method is carefully investigated. Conditions for when the tailbiting method fails are given, and methods for the proper initialization of the encoder are presented. Furthermore, the minimum distances of the tai

The main purpose has been to evaluate existing set points (thresholds) and suggest proper set points, for the regulation of the air change rate in a demand controlled mechanical ventilation (DCV) system. The DCV is controlled by measurements in the supply and exhaust air of the vapor content and volatile organic compounds (VOCs) for each dwelling in multifamily houses. Results have been achieved t

Gas turbine systems are predominantly designed to be fuelled with gaseous fuels within a limited Wobbe index range (typically HHV=45-55 MJ/Nm3 or 1200-1480 Btu/scf). When low calorific fuel gases are fired, the engine will be forced to operate outside its design envelope. The added mass flow will typically raise the cycle pressure ratio and in two-shaft designs also raise the gas generator shaft s

Children’s biographies are only rarely and more recently considered. In this paper, we make a case for thinking biographically about children’s relational lives. Using two qualitative case studies from research with children in middle childhood, in the UK and Sweden, we attend to the materiality of children’s biographies. We explore the way in which home spaces, possessions, family mementoes and m

Diffusion MRI is an imaging technique capable of inferring information about the tissue microstructure, based on magnetic resonance imaging (MRI). Diffusion MRI data can be analysed using tractography, a tool able to represent the structure of the white matter (WM) in the brain. Tractography is commonly used qualitatively, but in this report, an algorithm for quantitative tractography was develope

This thesis visits the forefront of algorithmic research on edge coloring of cubic graphs. We select a set of algorithms that are among the asymptotically fastest known today. Each algorithm has exponential time complexity, owing to the NP-completeness of edge coloring, but their space complexities differ greatly. They are implemented in a popular high-level programming language to compare their p

Sammanfattning I svensk rätt finns flera inskränkningar av den personliga avtalsfriheten. Pactum turpe är en av dessa och inskränkning innebär att vissa former av avtal som faller under den inte erhåller rättsordningens skydd. Under denna bestämmelse innefattas avtal som står i strid med lag eller goda seder, varav den senares innebörd är närmast omöjlig att fastslå. För att avgöra om ett avtal fa

AIMS: Atrial fibrillation cycle lengths can be assessed from right precordial ECG leads and the unipolar oesophageal ECG using a non-invasive method called Frequency Analysis of Fibrillatory ECG. The purpose of this report is to present the results from application of this method in a large group of patients with long-term atrial fibrillation and to examine the differences between patients with 'c

Background Presona AB manufactures fully automatic balers and compactors for waste management. A simple and clear supply chain is wanted. High inventory costs and long lead time have been identified; the long lead time partly is due to insufficient supplier processes. The company is not satisfied with the stock turnover. The communication with the suppliers today is handled by fax which is time de

Introduction: Gestational diabetes is on the rise and demographics are changing in many countries due to increased migration. Simultaneously, the treatment of gestational diabetes in our clinic has shifted towards metformin with substantially less insulin treatment. The aim was to study the impact of these changes on metabolic control and pregnancy outcome by comparing women diagnosed with gestati
