In order to enable a magnetic resonance imaging (MRI) only workflow in radiotherapy treatment planning, methods are required for generating Hounsfield unit (HU) maps (i.e., synthetic computed tomography, sCT) for dose calculations, directly from MRI. The Statistical Decomposition Algorithm (SDA) is a method for automatically generating sCT images from a single MR image volume, based on automatic t

In this study a dispersive liquid-liquid microextraction (DLLME) method based on the dispersion of an extraction solvent into aqueous phase in the presence of a dispersive solvent was investigated for the preconcentration of Cu2+ ions. 8-Hydroxy quinoline was used as a chelating agent prior to extraction. Flame atomic absorption spectrometry using an acetylene-air flame was used for quantitation o

Abstract Type 2 diabetes mellitus is among the fastest growing diseases in the world. The reported prevalence of T2D appears to differ among various ethnic groups. Although ethnic-related differences in lifestyle factors may account for some of the predisposition to diabetes in various ethnic groups, genetic factors may play a more determinant role.High prevalence rates of T2D have been reported

This paper presents an experimental evaluation of the performance of cubic boron nitride (CBN) tools in the machining of high-chromium white cast iron. Two types of CBN tool materials were evaluated in the tests, including polycrystalline cubic boron nitride (pCBN) and binder-less crystalline cubic boron nitride (bCBN). Performance in terms of the levels of cutting forces, tool wear, surface rough

Brownlielloideae, a new subfamily in the Teloschistaceae, is proposed based on phylogenetic analyses of nuclear ribosomal DNA and 12S SSU mitochondrial DNA sequences. The data indicates that the new subfamily includes eight genera, i.e. Brownliella, Marchantiana and six new genera proposed here, Lazarenkoella, Raesaeneniana, Streimanniella, Tarasginia, Tayloriella and Thelliana. Lecanora kobeana N

To identify differences in seed lignin content, 520 randomly chosen independent lines were screened in mutagenized oat population and lines with the seed lignin levels ranging from 20 to 63 gkg(-1) were identified. In the commercial variety Belinda, from which the mutated population was developed, seed lignin level was determined to be 41 g kg(-1). In Assiniboia, a Canadian low lignin variety, it

The primary objective was to estimate serum thymidine kinase 1 (TK1) activity, reflecting total body cell proliferation rate including cancer cell proliferation, in women with loco regional inoperable or metastatic breast cancer participating in a prospective and randomized study. Secondary objectives were to analyze TK1 in relation to progression-free survival (PFS), overall survival (OS), therap

This dissertation examines aspects of the experience of being a student at Nääs’ sloydseminar between 1880 and 1940 and what consequences it had for the participants. The experience was more or less consciously constructed by the charismatic leader Otto Salomon and after his death in 1907 the responsability of ”composing” the experience was put on Rurik Holm, pedagogical manager between 1913 and 1

Artikeln utgår från Magnus Perssons studie av legitimeringar i svenska läroplaner i "Varför läsa litteratur" (2007) och gör motsvarande undersökning av de ryska läroplaner som publicerats sedan 1991. Legitimeringar har extraherats ur läroplaner från 1997 och 2004. Dessa delas sedan in i kategorierna individcentrerade, samhällscentrerade och litteraturcentrerade. Legitimeringarna fördelade sig förh

Kerstin Thorvall (1925–2010) is a Swedish author of books for children and young adults, as well as books for adults. In 1965, she wrote the article “Do all authors of children's books live in Tomtebolandet?” (“Bor alla barnboksförfattare i Tomtebolandet”, Expressen 1965) in which she claims that gender roles in Swedish children's literature, are depicted in an old and stereotypical fashion. She a

OBJECTIVE-We report here genotyping data and type 1 diabetes association analyses for HLA class I loci (A, B, and C) on 1,753 multiplex pedigrees from the Type 1 Diabetes Genetics Consortium (T1DGC), a large international collaborative study. RESEARCH DESIGN AND METHODS-Complete eight-locus HLA genotyping data were generated. Expected patient class I (HLA-A, -B, and -C) allele frequencies were cal

In some situations the closed-loop system obtained by L1 adaptive control is equivalent to linear systems. The architectures of these systems are investigated and compared with internal model control and the input observer architecture. The analysis is focused on aerospace application. An effort has been made to understand and describe what fundamental control characteristic of flying applications

At present, the conversion of oils to biodiesel is predominantly carried out using chemical catalysts. However, the corresponding lipase-catalysed process has important advantages, which include mild reaction conditions and the possibility of using cheap, low quality feedstocks with a high free fatty acid content. Further increases in the efficiency of the enzymatic process are desired to make it

Aims The aims were to (i) investigate initial construct validity of a tool for assessment of time allocation in occupational balance, and (ii) describe perceived occupational balance and its relationship with socio-demographics, well-being, and personal recovery among people with mental illness. Methods Satisfaction with Daily Occupations and Occupational Balance (SDO-OB) was administered to 226 p

Building a detailed understanding of the structure function relationship is a crucial step in the optimization of molecular photocatalysts employed in water splitting schemes. The optically dark nature of their active sites usually prevents a complete mapping of the photoinduced dynamics. In this work, transient X-ray absorption spectroscopy highlights the electronic and geometric changes that aff

Cancer of unknown primary (CUP) is diagnosed at the metastatic stage. We aimed to identify hidden primary cancers in CUP patients by comparison with cancers in family members. We take use of the fact that the cause of death in CUP patients is often coded as the cancer in the organ of fatal metastasis. Forty-one thousand five hundred and twenty-three CUP patients were identified in the Swedish Fami
