Synthetic gas (syngas) fuels are promising energy sources in the future. In the current work, laminar flame speeds of typical syngas with different H-2 contents were studied using both experimental measurements and kinetic simulations. Measurements were carried out using the Bunsen method with the flame area derived from the OH planar laser-induced fluorescence (OH-PLIF) images; while kinetic simu

Objective: To determine whether preterm birth is associated with epilepsy in a national cohort of adults aged 25-37 years. Methods: We conducted a national cohort study of 630,090 infants born in Sweden from 1973 through 1979, including 27,953 born preterm (< 37 weeks), followed from 2005 to 2009 for 1) hospitalization for epilepsy and 2) outpatient and inpatient prescription of antiepileptic drug

Emissions and fuel economy are evaluated for two types of biofuels, namely 2-phenyl ethanol and cyclohexaneethanol. Both are derived from lignin, a form of lignocellulosic biomass. The former and latter oxygenates have an aromatic and aliphatic (i.e. saturated) ring structure, respectively. Two parametric engine sweeps were performed. First, non-EGR operation by means of varying the load via injec

Popular Abstract in Swedish Produkter bestående av polymera material produceras i allt större omfattning. Materialen används därför i fler tillämpningar där deras specifika egenskaper kommer till användning. Materialens förmåga att modifieras för att passa en specifik tillämpning motiverar materialgruppens ökade betydelse. Idag används polymera material mer eller mindre i alla branscher t.ex. tran

This thesis concerns vascular endothelial growth factor (VEGF) and its possible role as a neurotrophic factor. I have investigated the effect of VEGF on neurons in culture but also in vivo, following a crush lesion of the sciatic nerve, and following nerve repair. Attempts were also made to unravel the mechanism by which VEGF affects neurons and Schwann cells, using a pharmacological approach in c

Evaluation, prioritization and selection of candidate requirements are of tremendous importance and impact for subsequent software development. Effort, time as well as quality constraints have to be taken into account. Typically, different stakeholders have conflicting priorities and the requirements of all these stakeholders have to be balanced in an appropriate way to ensure maximum value of the

The aim of this study was to evaluate the beta cell and incretin function in patients with HNF4A and HNF1A MODY during a test meal. Clinical characteristics and biochemical data (glucose, proinsulin, insulin, C-peptide, GLP-1 and GIP) during a test meal were compared between MODY patients from eight different families. BMI-matched T2D and healthy subjects were used as two separate control groups.

Human recognition of the actions of other humans is very efficient and is based on patterns of movements. Our theoretical starting point is that the dynamics of the joint movements is important to action categorization. On the basis of this theory, we present a novel action recognition system that employs a hierarchy of Self-Organizing Maps together with a custom supervised neural network that lea

Background: Chronic Pseudomonas aeruginosa (PA) infection causes increased morbidity and mortality in cystic fibrosis (CF). This study aimed to answer the following questions: Does the prevalence of chronic infection with PA differ between the CF centres in Scandinavia? Which differences exist concerning segregation and treatment of PA? Methods: 989 patients (86%) from all eight CF-centres in Scan

Shannon's seminal approach to estimating information capacity is widely used to quantify information processing by biological systems. However, the Shannon information theory, which is based on power spectrum estimation, necessarily contains two sources of error: time delay bias error and random error. These errors are particularly important for systems with relatively large time delay values and

We consider central exclusive production of gg dijets in proton-proton (proton-antiproton) collisions at LHC and Tevatron for different intermediate and final gluon polarizations. The amplitude for the process is derived within the k(perpendicular to)-factorization approach (with both the standard QCD and the Lipatov's effective three-gluon vertices) and is considered in various kinematical asympt

The article analyzes the recent genre of Islamic children’s picture books, originally produced as a means of religious socialization for the British Muslim communities, but marked on a global Islamic market. Particular attention is devoted to the visual norms of the books produced by one of the pioneering publishers of Islamic children’s literature, the Islamic Foundation. With one foot in the ped

To ascertain the epigenomic features, i.e., the methylation, non-coding RNA, and gene expression patterns, associated with gain of i(12p) in Pallister-Killian syndrome (PKS), we investigated single cell clones, harboring either disomy 12 or tetrasomy 12p, from a patient with PKS. The i(12p)-positive cells displayed a characteristic expression and methylation signature. Of all the genes on 12p, 13%

Objectives. To identify patients with severe extra-articular RA (ExRA) in an early RA cohort and to investigate potential risk factors. Methods. From a cohort (n = 2900) in a structured programme for newly diagnosed RA, 40 patients with severe ExRA after RA diagnosis were identified. Disease activity score (DAS28), functional disability (HAQ) and treatment with glucocorticosteroids (GCs) and DMARD

Nilsson MH, Rehncrona S, Jarnlo G-B. Fear of falling and falls in people with Parkinson's disease treated with deep brain stimulation in the subthalamic nuclei. Acta Neurol Scand: 2011: 123: 424-429. © 2010 John Wiley & Sons A/S. Background - No previous study prospectively investigated the effects of subthalamic deep brain stimulation on fear of falling (FOF) and falls. Aim - The aim was to p

OBJECTIVE: To evaluate feasibility and morbidity of robot assisted laparoscopic radical hysterectomy. METHODS: From December 2005 to September 2008 robot assisted laparoscopic radical hysterectomy and pelvic lymphadenectomy was performed on 80 women. Using a prospective protocol, and an active investigation policy for defined adverse events, perioperative, short and long term data were obtained. R

Introduction Many kinds of footwear are used for various purposes in the workplace in Japan. Careful selection of footwear is needed to protect workers from coldness and to keep the performance of workers in cold workplace where employees have to work under -20℃. On the other hand, safety boots with high heat conductivity from foot to outside are needed for the workers in hot environments. But the

Carotid surgery prevents recurrent stroke in patients with symptomatic tight stenosis of the carotid artery. The Swedish Carotid Surgery Monitoring Registry seeks to promote selection of patients with significant spontaneous risk for recurrent stroke, with an eye toward expediting evaluation and minimizing surgical complications. To this end, professionals at participating hospitals are informed a
