I Sverige drabbas omkring 300 barn av cancer varje år och majoriteten av dem är bara fyra-fem år gamla när de får sin diagnos. Omkring två tredjedelar av barncancerdiagnoserna utgörs av leukemier, lymfom och hjärntumörer, medan den sista tredjedelen är olika solida tumörformer som njurtumörer och nervvävnadstumörer i buken. Cancersjukvårdens utveckling under de senaste årtiondena har medfört en avPurpose: The purpose of this study was to evaluate the impact of including PET (Positron Emission Tomography) in the process of pediatric radiation therapy planning. The aim was to study the effect on target volumes and how this in turn affects the resulting treatment plans. This study also aims to compare the estimated risks of various long-term complications and how the use of PET influences the

How professions should be defined and separated from other occupations has constituted an enduring theoretical and empirical problem in studies of the professions. In this article, the definitions of the so-called list approaches, involving enumerations of social attributes, are scrutinized. Weak-nesses are highlighted and analysed. It is argued that an alternative approach to the issue of definit

Cellular Neural Networks are characterized by simplicity of operation. The network consists of a large number of nonlinear processing units; called cells; that are equally spread in the space. Each cell has a simple function (sequence of multiply-add followed by a single discrimination) that takes an element of a topographic map and then interacts with all cells within a specified sphere of intere

More than 550 breast adenocarcinomas with clonal chromosomal abnormalities have been reported. Although the aberration pattern is clearly nonrandom, no specific primary or secondary karyotypic abnormality has been identified, and furthermore the chronological order in which the aberrations appear during disease progression is not well known. The high degree of karyotypic complexity in epithelial t

Investigating the meaning of conceptual terms is an important task for international legal scholars. In the analysis of the usage of conceptual terms in international legal discourse, traditionally, most international lawyers have confined studies to the descriptive meaning of those terms. They have assumed that conceptual terms describe a relationship between, on the one hand, the particular prop

The issue of understanding how electrical and mechanical systems work and how the components interact is not a trivial issue for most people. To help students understand these systems and thereby increase the knowledge for the future engineers, educational computer games may act as an important learning platform. This project aims at aiding students in their effort to reach knowledge in the area o

Abstract Author: Carina Ljungwald Title: The Social Services’ Provisions on Crime Victims – a study of their origins and purposes Supervisor: Kerstin Svensson In 2001, crime victims were introduced as a target group in the Swedish Social Services Act. Alongside special provisions concerning children, youths, elderly persons, persons with functional impairments, substance abusers and family caregiv

This is a Master Thesis carried out for and done in cooperation with Getinge Water System A/S. The purpose of the thesis was to develop a new separation system for their Pure Steam Generator. The focus was set on making it smaller without affecting separation efficiency and manufacturing costs. During the projects course, objectives were altered and size was no longer highly prioritized; instead,

Escherichia coli flavohemoglobin (HMP), which contains one heme and one FAD as prosthetic groups and is capable of reducing O-2 by its heme at the expense of NADH oxidized at its FAD site, was electrochemically studied at graphite (Gr) electrodes. Two signals were observed in voltammograms of HMP adsorbed on Gr, at -477 and -171 mV vs. Ag vertical bar AgCl, at pH 7.4, correlating with electrochemi

Background: The identification of novel genes by high-throughput studies of complex diseases is complicated by the large number of potential genes. However, since disease-associated genes tend to interact, one solution is to arrange them in modules based on co-expression data and known gene interactions. The hypothesis of this study was that such a module could be a) found and validated in allergi

Angular correlations between charged trigger and associated particles are measured by the ALICE detector in p-Pb collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV for transverse momentum ranges within 0.5 < P-T,P-assoc < P-T,P-trig < 4 GeV/c. The correlations are measured over two units of pseudorapidity and full azimuthal angle in different intervals of event multiplicity, and exp

Motivationen med studien var den alldeles för höga stråldosen som används vid CTundersökningar. I de allra flesta fallen anpassas man inte rörströmmen efter patientens storlek och därmed får smalare patienter en onödigt hög stråldos. Målet var att reducera stråldosen till patienter som undersöks med datortomografi utan att minska på bildkvalité, genom att anpassa rörströmmen efter patientens stoIn this study we have investigated the possibilities of dose reduction in CT at a constant level of image quality by adjustment of the tube current to the phantom size. The motivation with the study is the high radiation doses to the patients and the increasing frequency of CT examinations and the variety of examinations in CT, and that the same tube current is used for different patient sizes. Ac

The postmaterialism thesis put forth by Ronald Inglehart stipulates a relationship between wealth and non-physical values. Among these values is the protection of the environment, meaning that wealthier populations should more readily prioritise measures that further this goal. The postmaterialism theory has been a matter of contention, however, and there’s substantial critique against it. One of

The purpose of this study is to investigate how and why companies are changing the nature of their CSR reporting in order to regain legitimacy, due to a scandal. The purpose is also to see if an indication of how media affects the reputation of the organisations’ can be found. Legitimacy theory. The authors’ have chosen a qualitative approach by using content analysis for investigating two compani

Anthropogenic land-use change (LUC) substantially impacts climate dynamics, primarily through modifications in the surface biogeophysical (BGP) and biogeochemical (BGC) fluxes, which alter the exchange of energy, water, and carbon with the atmosphere. Despite the established significance of both the BGP and BGC effects, their relative contribution to climate change remains poorly quantified. In th

This study compares the sample variance of the mean in a simple random sample (SRS) and a systematic sample from a surface. The study also compares the prediction error variance in a SRS and systematic sample from a random field. Recommendations are presented on which method to use in the clearance and exemption process in the nuclear industry. The results indicate that quadratic systematic sampli
