Popular Abstract in Swedish Den värld vi lever i drivs till stora delar av förbränning. Det mesta vi gör kräver energi, elektricitet för matlagning och bensin eller diesel för transporter. Sett över hela världen kommer den största delen av den energi som förbrukas från förbränning. Främst är det fossila bränslen, olja och kol, som används, men en ökande del kommer från förnyelsebara bränslen. Vid The work reported here includes experimental studies of lean premixed swirling flames. Various laser-based optical diagnostic techniques were used to collect information under different operational conditions. Combined flow- and scalar field measurements were performed at high repetition rates for detailed studies of the turbulent flames. A large part of the work presented concerns experimental

Left atrial (LA) enlargement is a pathophysiological response to volume overload resulting from chronic mitral regurgitation (MR), is known as LA remodeling, and has been shown previously to be associated with cardioembolic events. Following mitral valve surgery (MVS), the left atrium may undergo reverse remodeling characterized by LA volume reduction. The study aim was to evaluate the incidence a

This article aims to share experience from a Swedish project on the introduction and implementation of Open Educational Resources (OER) in higher education with both national and international perspectives. The project, OER – resources for learning, was part of the National Library of Sweden Open Access initiative and aimed at exploring, raising awareness of and disseminating the use of OER and th

Objective. The first changes in the diabetic kidney are glycogen deposits in the epithelial cells of the thick ascending limb of Henle. These cells produce Tamm-Horsfall protein (THP). Is low excretion of THP associated with the development of renal insufficiency or cardiovascular disease? Material and methods. Urine samples were collected at baseline in patients with type 1 (n=131) and type 2 (n=

BACKGROUND: The chosen method of speech assessment, including type of speech material, may affect speech judgement in children with cleft palate.AIM: To assess the effect of different speech materials on speech judgement in 5-year-old children born with or without cleft palate, as well as the reliability of materials by means of intra- and inter-transcriber agreement of consonant transcriptions.ME

Consider a parametrized family of general hidden Markov models, where both the observed and unobserved components take values in a complete separable metric space. We prove that the maximum likelihood estimator (MLE) of the parameter is strongly consistent under a rather minimal set of assumptions. As special cases of our main result, we obtain consistency in a large class of nonlinear state space

A selective extraction technique based on the combination of membrane assisted solvent extraction and molecularly imprinted solid phase extraction for triazine herbicides in food samples was developed. Simazine, atrazine, prometon, terbumeton, terbuthylazine and prometryn were extracted from aqueous food samples into a hydrophobic polypropylene membrane bag containing 1000 mu L of toluene as the a

Popular Abstract in Swedish Pankreascancer (cancer i bukspottkörteln) utgör fjärde orsak död i cancer. Det är den cancerform som har den dystraste prognosen av alla, med en 5-års överlevnad mindre än 6%. Sjukdomsrelaterade symptom uppträder ofta sent i förloppet och det saknas metoder för tidig diagnos varför de flesta av patienterna upptäckts i sent skede. Endast cirka 20 procent av patienterna kPancreatic cancer (PC) is the fourth leading cause of cancer-related deaths, with a 5-year survival less than 6%. It does not show any symptoms in its early stages, hence most (>85%) of the patients are diagnosed at late stage. At the time of diagnosis, metastases are frequently observed which make most patients unsuitable for curative surgical treatment and chemotherapy remains the only choice fo

Here, we investigated the structure of natural montmorillonite (MMT) and modified Cloisite C15A (MMT pre-intercalated with a dimethyl-dehydrogenated tallow quaternary ammonium surfactant) nanoclays in the wheat gluten-urea matrix in order to obtain a nanocomposite with improved barrier and mechanical properties. Small-angle X-ray scattering indicated that the characteristic hexagonal closed packed

Objective The aim of this study was to describe the frequency, attribution, outcome and predictors of seizures in systemic lupus erythematosus (SLE). Methods The Systemic Lupus International Collaborating Clinics, or SLICC, performed a prospective inception cohort study. Demographic variables, global SLE disease activity (SLE Disease Activity Index 2000), cumulative organ damage (SLICC/American Co

The development and expansion of evaluation theory and practice is at the core of several different disciplines. There exist different traditional Information System (IS) evaluation approaches, like experimental, pragmatic, constructivist, pluralist and realist IS evaluation. IS evaluation approaches are influenced by the way they address to technology. Recently actor network theory (ANT) and soci

Popular Abstract in Swedish När det blir stopp i ett av hjärtats kranskärl blockeras blodflödet till hjärtat, vilket kan orsaka blodbrist i en del av hjärtmuskeln. Detta kan i sin tur leda till hjärtinfarkt, vilket tar död på hjärtmuskelceller och skadar hjärtat. Vid den efterföljande behandlingen av hjärtinfarkt kan små proppar i kranskärlen, så kallade mikroembolier, ytterligare förvärra skadan Myocardial infarction (MI) following an acute coronary occlusion is a leading cause of morbidity and mortality. During revascularization, microemboli may complicate treatment and affect cardiac function. The long-term effects of microembolization are not fully elucidated. Following an MI it is important to accurately determine the size of the infarction, as it can be used for guidance in terms of

Utifrån aktuell forskning kring publik och reception, och mot bakgrund av en förskjutning inom samtidens scenkonst mot åskådarnas delaktighet och medansvar söker texten uppvärdera publiken och de många aspekter av teaterhändelsen som receptionsperspektivet aktualiserar, och bidra till en omdefiniering av teaterns problem och dess uppdrag visavi publiken.

AimOral mucositis is a common and debilitating side effect of haematopoietic stem cell transplantation. Our study investigated parents' and children's experiences of oral mucositis treatment and whether the parents' perceptions accurately reflected the children's views. MethodsWe analysed 71 questionnaires completed by the parents of children who had undergone haematopoietic stem cell transplantat

Based on a known observation that symplecticity is preserved under certain Sundman time transformations, adaptive symplectic integrators of an arbitrary order are constructed for separable Hamiltonian systems, for two classes of scaling functions. Due to symplecticity, these adaptive integrators have excellent long-time energy behaviour, which is theoretically explained using standard results on t

Quinoa stalk (Chenopodium quinoa Willd.) from agricultural crop residue, totora (Schoenoplectus tatora) and o-macrophytes (aquatic flora) from Lake Titicaca (on the Bolivian Altiplano) were studied in a wet anaerobic co-digestion process together with manure front llama, cow and sheep. Anaerobic semi-continuous experiments were performed in (10) 2-1 reactors at a temperature of 25 degrees C with 3

Very old persons (80+) are often described as "frail", implying that they are particularly vulnerable to adverse health outcomes. Elderly Persons in the Risk Zone was designed to determine whether a preventive home visit or multiprofessional senior group meetings could postpone deterioration in frailty if the intervention is carried out when the person is not so frail.

Heterostructure nanowires have many potential applications due to the avoidance of interface defects by lateral strain relaxation. However, most heterostructure semiconductor nanowires suffer from persistent interface compositional grading, normally attributed to the dissolution of growth species in the common alloy seed particles. Although progress has been made for some material systems, most bi
