PURPOSE: We determined how serial measurements of prostate specific antigen and alkaline phosphatase can be used to predict survival early in the course of hormone treated metastatic prostate cancer. MATERIALS AND METHODS: The study was based on a prospective randomized trial of 915 patients with metastatic prostate carcinoma designed to compare parenteral estrogen (polyestradiol phosphate) vs tot
Continuous production control is important for the production using Tetra Pak equipment, as problems that are found early in the chain of production can minimize the need for waste greatly. In production of paper straws, a possible production control could be to photograph straws during production, analyse these and predict how good the straw is, using the image. If the predicted performance of th
This thesis presents the temperature dependence of InGaAs Nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs) grown at two different temperatures. The two different growths represent one sample having nanowires which have a mixed crystal structure (showing stacking faults) and one sample with nanowires of pure crystal structure (without stacking faults). The sample with a pu
Organized crime has received much attention in Sweden the last decade and it is seen as a big threat against the society. In 2007 the government emphasized the importance to fight this type of criminality by taking a first initiative towards a national campaign against organized crime. Further the Minister of Justice wants to investigate whether it is possible to introduce a crown witness system i
Recent years have seen an explosion in innovative and sustainable mobility service offerings, especially car sharing and bike sharing. The latter contribute to sustainability by reducing individual car ownership, which has negative social, economic and especially environmental consequences. Yet, both industrial and academic discourses point out that no single mobility service is enough to meet the
Abstract Author: Patricia Pawlowska and Fatime Juka Title: Substitute treatment – the way out of an addiction or continuation of a long – term addiction? A qualitative study of substitute treatment from a user perspective. Supervisor: Erika Werner Keywords: substitute treatment, subutex, methadone, drug abuse and heroin. Aim: the aim of this study is to investigate how former drug addicts perce
Automatic segmentation of organs and tissues in computed tomography (CT) images can aid clinicians in anatomical contextualization for planning surgery or dosimetry. CT scans can cover varying axial ranges of the body. This thesis aims to develop a neural network based on vision transformers for segmenting organs and tissues in CT images of arbitrary axial ranges. Two models are presented, one bas
The widespread use of plastic mulch in agriculture is rapidly increasing due to intensified farming practices. While plastic mulch can enhance crop yields significantly, it also introduces challenges related to waste management and environmental degradation. This study focuses on the application of Sentinel-2A imagery and the Maximum Likelihood Classifier (MLC) to classify plastic foils used in ea
Problem discussion: To be more competitive, Trading Area Wood is working on developing their suppliers in efficiency projects. However, they find it hard to motivate their suppliers to take part in the projects. Therefore, they need a way to show the suppliers the positive effects of participating in the efficiency projects. Moreover, Trading Area Wood has troubles to predict the economical outcom
The objective of the research is to identify the improvement gap and provide suggestions in green transportation for Skånemejerier, a dairy company in the region of Skåne, Sweden. The findings are divided into two main topics, firstly, the review on environmental policy documents, which is the foundation of gaining capability in environmental management and secondly, the result of benchmarking in
En dendrokronologisk undersökning har gjorts på 128 tallar (Pinus sylvestris) från två torvmossar: Viss mosse och Åbuamossen i Skåne, södra Sverige. De delar av torvmossars lagerföljd som innehåller stubbar och stammar bildar stubbhorisonter. En stubbhorisont i en lagerföljd representerar en torrare fas i mossens historia, oftast som ett resultat av hydrologiska variationer orsakade av klimat föräIn total 128 pine samples (Pinus sylvestris) from two raised peat bogs, Viss mosse and Åbuamossen, Skåne, southern Sweden were examined with dendrochronological methodology. The result is a number of floating chronologies, of which the longest cover 570 years. The three most valuable chronologies were 14C-dated to construct dated chronologies. These chronologies are of certain dendrochronological
Populärvetenskaplig sammanfattning: Echinodermerna räknas som en mycket viktig del av den marina faunan. Bland echinodermerna återfinns djur som sjöstjärnor, sjöborrar, ormstjärnor och sjöliljor. Gemensamt för dessa är att de alla byggs upp av ett skelett av mindre delfragment, plåtar, där byggnadskomponenten för själva "skelettet" är kalcit. Kalcit är ett mineral som förekommer som en vPhosphatization of late Early Ordovician echinoderm fragments from N Öland has resulted in excellent preservation of the echinoderm stereom ultra structure. The stereom investigated shows a close relationship to different types found in recent echinoderms. The several different types of phosphatic preservation found have been controlled by diagenetic relationships. The original stereom structures
Under de senaste 15 åren har användningen av frekvenselektromagnetiska sonderingsinstrument inom geofysiska undersökningar drivit forskningen framåt för att förbättra den använda metoden. En av dessa tekniker är inversion vilket är den process som omvandlar elektromagnetiska data till djupvärden för geologiska lager. Inversion av frekvenselektromagnetiska data har länge varit förknippat med svårigThe adoption of frequency electromagnetic (EM) sounding devices in the past 15 years for geophysical exploration has fueled research into techniques associated with the method. One of these techniques is inversion which is the process of turning the EM data into measurements of depth for different geological layers. Inversion of frequency EM data has classically been difficult and unreliable. With
Title The profession of Children's Librarians. Identity and vocation. Abstract The aim of this Master's thesis is to investigate the professional identity of Children's Librarians in order to contribute to a deeper understanding to the professions of librarians. This places the thesis in the field of Library and Information Science that studies the profession. The definition we use
The purpose of this essay is to analyse how the leadership and the structure of the organization affect the process of changes within a specific department in Lunds kommun socialdepartment, from the director of social work to the co-workers at Utredningsenheten för ungdom och familj. We aim to answer the following questions; How does the structure of organisation affect the process of change? Wh
My purpose of this study was to examine LSS staffs’ (LSS: The Swedish Act concerning support and service for persons with certain functional Impairments) consideration of clients’ needs and self-determination as well as the staffs’ own power in the use of coercion and restraint in the work with clients in group housings. My study was based on five interviews with staff from two different group hou
Neural electrodes used for measurements of action potentials in brain cells are often made of gold. These electrodes need to be suciently small to cover only one brain cell, but this induces the problem of increased impedance since impedance scales inversely with surface area. This means that if the surface area is too small, only noise will be measured. One way to overcome this problem is to try
