Ergonomics are, in most cases, focusing on the human being when evaluating assembly system designs. This results in the human performance being expressed isolated from the technical environment. On the other hand, technicians are prone to concentrate on the hardware. These conditions underline the need to pursue a more integrated evaluation and design procedure in order to avoid the drawbacks of t

The Sectra MicroDose Mammography system is based on direct photon counting (with a solid-state detector), and a substantially lower dose to the breast than when using conventional systems can be expected. In this work absorbed dose measurements have been performed for the first unit used in routine mammography screening (at the Hospital of Helsingborg, Sweden). Two European protocols on dosimetry

In this paper we explore the potential of cross-fertilization between research on welfare state reforms and on efforts to green the state in response to ecological challenges. In order to gain a deeper understanding of the conditions for an ecological state to emerge we relate welfare state studies to green political theory, that provide different conceptions of the ecological state and ways to gr

This paper presents a decomposition strategy applicable to DAE constrained optimization problems. A common solution method for such problems is to apply a direct transcription method and to solve the resulting non-linear program using an interior point algorithm, where the time to solve the linearized KKT system at each iteration is dominating the total solution time. In the proposed method, the s

This bachelor’s thesis examines five selected works of art by the Swedish painter Leander Engström (1886–1927), created between 1915 and 1919. This period is generally regarded as the most significant phase of Engström’s artistic production and was shaped by his time spent in Abisko, as well as by a romantic relationship that coincided with an especially vivid and expressive phase in his work. Eng

There has recently been much interest in Gaussian fields on linear networks and, more generally, on compact metric graphs. One proposed strategy for defining such fields on a metric graph Γ is through a covariance function that is isotropic in a metric on the graph. Another is through a fractional-order differential equation Lα/2 (τu) = W on Γ, where L = κ2 − ∇(a∇) for (sufficiently nice) function

Populärvetenskaplig sammanfattning: I en mosse i södra Sverige, som heter Viss mosse, har fynd av trädstammar gjorts. Fynden gäller ek, bok och al. Denna horisont med trädstammar tyder på att miljön på mossen var förhållandevis torr när träden levde, eftersom det normalt sett är för blött på en mosse för att ekar och bokar ska kunna växa där. Kol-14-dateringar visar att träden dog för cirka 3 200 Findings of a tree stump horizon in Viss mosse, a raised bog in Scania, southern Sweden, indicate relatively dry conditions on the bog during the lifetime of the trees . 14C-datings show that the trees died about 3 200 years ago. Four peat cores were collected from the bog in order to investigate whether climatically induced water level fluctuations were responsible for establishemt and death of t

A shear-enhanced, cross-flow ultrafiltration module was used to separate cells and proteins from the fermentation broth. Three (fermented) media were studied: rich medium, rich medium with hydrolytic enzymes added after fermentation, and wheat flour hydrolysate. To find a membrane with as high a flux as possible, but still capable of separating cells and proteins from the lactic acid containing br

The top quark pair production and decay are considered in the framework of the smeared-mass unstable particles model. The results for total and differential cross-sections in vicinity of t (t) over bar threshold are in good agreement with the previous ones in the literature. The strategy of calculations of the higher order corrections in the framework of the model is discussed. Suggested approach

Using classical design optimization methods for implant-bone studies does not completely guarantee a safety and satisfactory performance, due in part to the randomness of bone properties and loading. Here, the material properties of the different bone layers are considered as uncertain parameters. So their corresponding yield stress values will not be deterministic, that leads to integrate variabl

Hösten 1943 genomförde Socialstyrelsen rasbiologiska mätningar av mer än hundra svenskar som myndigheten ansåg var ”tattare”, däribland flera barn. Genom att mäta längden på näsor, armar och pannor ville myndigheten få fram ett objektivt sätt att avgöra vilka svenskar som borde kategoriseras på detta sätt. Målet var att skapa särskilda politiska åtgärder mot gruppen, som länge givits skulden för eSince the 16th Century, there has been Travelling families in Sweden, earning their living by itinerant trades such as horse-trading, scrap-metal-dealing and tinplating. The authorities often labelled these families “tattare”. They suffered from severe discrimination, and authorities as well as scientists claimed that they were a threat against society. These claims were often made with a racializ

Endovascular treatment had developed rapidly and the procedures have increased in complexity. The demand of imaging excellence is imperative to perform these interventions. However both pre and postoperative investigations are performed by the use of advanced three-dimensional imaging, while the treatment itself relies on two-dimensional imaging. With the use of Cone Beam Computed Tomography (CBCT

Purpose. The purpose of this study was to test the General Motor Function Assessment Scale (GMF) for content and criterion validity in geriatric home-rehabilitation. Furthermore, the GMF was analysed with respect to sensitivity, distribution, and for floor and ceiling effects. Method. Content validity was explored by questionnaires circulated to ten experts in the field of geriatrics. Three assess

Teachers in Social Studies can benefit from geographical perspectives in their teaching of Social Studies in elementary and high school. The aim is to connect geographical perspectives to various social processes and to integrate it in teaching of Social Studies. But how can the relevance of geographical perspectives in an education for teachers in Social Studies be motivated and to what benefits

The Dominican Republic is a small open economy, highly dependent on trade for its economic growth. During the past decades, the country has taken major steps to liberalize its trade regimes. As a consequence revenues from import duties and tariffs have fallen sharply. This has put an immediate pressure on the country to reform its tax system in order to increase revenue from domestic sources to co

Ett av syftena med denna uppsats är att undersöka tre olika metoder att använda satellitdata för detektering av stormskador i skog. Undersökningen är gjord i Kronobergs län som drabbades hårt av stormen Gudrun den 8 – 9 januari 2005. Ett andra syfte undersöktes vilka variabler, förutom vind, som påverkat den spatiala spridningen av stormskador. De variabler som undersökts är; Höjd över havet, slut

By ratifying ILO Conventions, ILO Member States undertake to bring national legislation and practice into full compliance with these international labour instruments. However, the question remains whether the countries actually implement their international commitments. The assessment of national compliance with the ratified ILO Standards may help to find out the good practices to be followed by

The purpose of this work is to do an investigation on the customers in the pharmaceutical sector; mainly general physicians who have taken part in the education events have any impact in their prescription behaviour after the participation in the program. The settings for this study are general practitioners in the Swedish market who have taken part in the education program held by Novo Nordisk in
