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

The thermal stresses in a concrete bridge are affected by the surrounding climate. Varying temperature will produce movements which, if restrained, may induce stresses in the structure. To predict the thermal stresses in box cross-sections, FE simulations have been performed with extensive climatic input data to simulate the temperature and resulting stress fields in the hollow concrete arch of th

Using tracking radars, we investigated the variability of flight directions of long-distance nocturnal passerine migrants across seasons (spring versus autumn migration) and sites at the southern (56A degrees N) and northern (68A degrees N) ends of the Scandinavian Peninsula (Lund versus Abisko). Whilst most migrants at Lund are on passage to and from breeding sites in Fennoscandia, the majority o

Introduction A study was undertaken to test the hypothesis that musculoskeletal pain is associated with low vitamin D levels but the relationship is explained by physical inactivity and/or other putative confounding factors. Methods Men aged 40-79 years completed a postal questionnaire including a pain assessment and attended a clinical assessment (lifestyle questionnaire, physical performance tes

Popular Abstract in Swedish Offentlig upphandling blir alltmer intressant och relevant som ämnesområde då dess sanna ekonomiska värde och potentiella inverkan på marknader - genom köpkraft – uppdagas. Det har dessutom blivit ett relevant område för hållbarhetsdiskursen då man har kommit att inse möjligheten att ställa miljökrav inom ramen för den offentliga upphandlingen, samt miljöanpassa upphandIn Sociology of Law the discussions about regulation have been extensive and the issue of public procurement is gaining momentum as its true financial value and potential to impact markets are realised. This thesis aims to look at the regulation of green public procurement (GPP) by analysing findings from an in-depth case study in a Swedish context, using interviews with procurement officers as we

Cross-like nanostructures composed of two perpendicular ferromagnetic (Ga,Mn)As nanowires were fabricated using electron-beam lithography patterning. Nanostructures of different orientations with respect to the crystallographic axes of the parent (Ga,Mn)As epitaxial layer were studied. Electrical resistance of individual nanowires as a function of applied magnetic field were investigated at low te

Syftet med denna studie är att analysera hur ungdomar som varit placerade på särskilda ungdomshem upplever, definierar och tolkar ett behandlingsprojekt, som involverade olika myndigheter, benämnt Motverka Våld och Gäng. Dessutom uppmärksammas hur de tolkade de i projektet anställda samordnarna. Den personliga aspekten i relationen mellan ungdomar och samordnare framställs som viktig och det verkThe purpose of this study is to analyse the way young people who were institutionalised in so called special youth-homes experienced, defined and iterpreted on the one hand the project “Motverka Våld och Gäng” (meaning: “Counteract Violence and Gangs”), and on the other hand the Coordinators employed in this project. There is a big variation in the perception of the coordinators. One common deno
