PIXE-analyser kan utföras med utvecklad analysuppställning med noggrannhet och precision av c:a 10 % och med hög analyskapacitet. Ett dataprogram för evaluering av räntgenspektra presenteras. Inverkan av provtjocklek vid PIXE-analys av inhomogena prov har studerats och korrektioner föreslås. Fluorinnehållet i filterprov har bestämts, samtidigt med PIXE-analys, genom utnyttjande av en kärnfysikalis
Objective: Developmental programming alters growth and metabolic outcome in children born small for gestational age (SGA). We explored insulin and glucose metabolism in SGA children treated with a fixed GH dose over 1 year. Methods: In the North European Small for Gestational Age Study (NESGAS), 110 short SGA children received GH at 67 mu g/kg/day for 1 year. Insulin secretion was assessed by acut
In this paper we look at opportunities to support the creation of value for all through the use of end-user-owned Virtual Personal Assistant. We use a chat-bot as example of technology with a possibility for transferring and diffusing new functionality, features and capabilities. This category of software can create potential value through its AI and natural language processing combined with emula
Previously the effect of atmospheric dispersion on telescope performance has attracted only relatively little attention. This may be due to the fact that the dispersion effects have been evaluated in relation to the size of the diffraction limited resolution angle of current telescopes, or to seeing limited telescopes. However, since the resolution angle is inversely proportional to telescope diam
For extremely large telescopes, there is strong need for thin deformable mirrors in the 3-4 m class. So far, feasibility of such mirrors has not been demonstrated. Extrapolation from existing techniques suggests that the mirrors could be highly expensive. We give a progress report on a study of an approach for construction of large deformable mirrors with a moderate cost. We have developed low-cos
This dissertation concerns the field of applied psychiatry and focuses on the problems that are associated with the care and treatment of adult patients with autism spectrum disorders. The conditions that are described are valid for Swedish psychiatry and cannot be directly generalized to conditions outside of the country.
Photodynamic therapy (PDT) for the treatment of prostate cancer has been demonstrated to be a safe treatment option capable of inducing tissue necrosis and decrease in prostate specific antigen (PSA). Research groups report on large variations in treatment response, possibly due to biological variations in tissue composition and shortterm response to the therapeutic irradiation. Within our group,
The protection of trade secrets in Portugal and Spain has been derived from general legal principles (of Civil Law, Penal Law and Unfair Marketing Law). This chapter on implementation of the Trade Secrets Directive (TS Directive) in Portugal and Spain presents the traditional views and positions and the implementation of the TS Directive into the respective national legal orders.In Portugal, imple
Reliable safe water supply is a pillar of society and a key to public health. The Nordic countries have an abundance of clean fresh water as a source for drinking water supplies. They have followed developments in safeguarding water, both the recommendations of the World Health Organization framework for safe drinking water and European legislation. Worldwide, including the Nordic countries, small
Purpose: Onyx® embolization causes severe artifacts on subsequent CT-examinations, thereby seriously limiting the diagnostic quality. The purpose of this work was to compare the diagnostic quality of the tailored metal artifact reducing algorithms iMAR to standard reconstructions of CTA in patients treated with Onyx® embolization. Method: Twelve consecutive patients examined with Dual Energy CTA a
Purpose: Neurofilament light (NfL) is a biomarker reflecting neurodegeneration and acute neuronal injury, and an increase is found following hypoxic brain damage. We assessed the ability of plasma NfL to predict outcome in comatose patients after out-of-hospital cardiac arrest (OHCA). We also compared plasma NfL concentrations between patients treated with two different targets of arterial carbon
Recent animal studies have shown that D-glucose is a potential biodegradable MRI contrast agent for imaging glucose uptake in tumors. Here, we show the first translation of that use of D-glucose to human studies. Chemical exchange saturation transfer (CEST) MRI at a single frequency offset optimized for detection of hydroxyl protons in D-glucose (glucoCEST) was used to image dynamic signal changes
Ischemic stroke causes transient increase of neural stem and progenitor cell (NSPC) proliferation in the subventricular zone (SVZ), and migration of newly formed neuroblasts toward the damaged area where they mature to striatal neurons. The molecular mechanisms regulating this plastic response, probably involved in structural reorganization and functional recovery, are poorly understood. The adapt
Popular Abstract in Swedish Vårt behov av att öka matproduktionen för en växande global befolkning, har sedan mitten av nittonhundratalet drivit jordbrukets utveckling. Det traditionella, småskaliga jordbrukslandskapet med sitt lapptäcke av betesmarker, ängar och åkrar, har över tid ersatts av ett mer produktionsinriktat landskap. Åkrar har slagits ihop för att skapa större odlingsenheter, där nyaThe intensification of agriculture during the second half of the twentieth century, has caused sever declines of farmland biodiversity, where loss of semi-natural habitats is one of the major drivers. To halt further loss of habitat and biodiversity, agri-environmental schemes (AES) are used to compensate farmers to use methods less harmful to the environment. In this thesis, I have investigated t
Popular Abstract in Swedish Den här boken handlar om ömsesidighet i sociala relationer - om vänskap. Den handlar också om de moraliska och rättsliga normer och föreställningar som istället främjar ensidiga, eller till och med direkt fientliga, relationer. Arbetet utgår från vissa centrala punkter i den aristoteliska etiken. Undersökningen kretsar kring de värden som konstituerar den sociala relatiThis is a book about reciprocity in social relationships - about friendship. It also deals with the moral and legal norms which, conversely, promote one-sided and even directly hostile relationships. The starting-point for this work is certain central elements in Aristotelian ethics. The study revolves around the values which constitute the social relationship of friendship and the central questio
The zinc finger transcription factor Wilms' tumor gene 1 (WT1) acts as an oncogene in acute myeloid leukemia. A naturally occurring alternative splice event between zinc fingers three and four, removing or retaining three amino acids (+/-KTS), is believed to change the DNA binding affinity of WT1, although there are conflicting data regarding the binding affinity and motifs of the different isofor
