The objective of this study was to examine to what extent ergonomics simulations of manual assembly tasks correctly predict the real outcomes in the plants and if recommended measures originating from ergonomics simulations are taken into consideration. 155 ergonomics simulation cases were used in the study and all cases were performed by nine simulation engineers at Volvo Car Corporation in Gothe

During the last decades the need to control the paper production process has grown, due to the technological development and the continuing increases in quality demands. Recent development of sensors and fast, high-capacity computers open up new possibilities for the development of high capacity monitoring systems for the paper industry. Optical methods have advantages for performing fast and high

In this report a generic model for the capture and assessment of end-user requirements and needs, the CREDIT carpenter model, has been developed. The main determinants of the model is the need for the project organisation (including the facilities management organisation) to ensure a thorough understanding of the end-user requirements and needs as well as an assessment through out the project proc

Since 2007, Intelligent Energy (IE) has been involved in developing technologies and services in the hydrogen generation space with E.ON Gas Sverige AB and Swedish Gas Centre. The aim of this work is to support the development of a high-profile demonstration of hydrogen generation technologies in a Swedish context. The overall objective of the demonstration is to deploy a reforming based hydrogen

Opaline silica deposits on Mars may be good target sites where organic biosignatures could be preserved. Potential analogues on Earth are provided by ancient cherts containing carbonaceous material (CM) permineralized by silica. In this study, we investigated the ultrastructure and chemical characteristics of CM in the Rhynie chert (c. 410 Ma, UK), Bitter Springs Formation (c. 820 Ma, Australia),

The capacity of murine liver dendritic cells (DC) to present bacterial Ags and produce cytokines after encounter with Salmonella was studied. Freshly isolated, nonparenchymal liver CD11c(+) cells had heterogeneous expression of MHC class II and CD11b and a low level of CD40 and CD86 expression. Characterization of liver DC subsets revealed that CD8alpha(-)CD4(-) double negative cells constituted t

The thesis deals with determination of the post peak behaviour of wood in pure tension and pure shear. Furhermore, the "Fictitious Crack Model" (FCM), which is a nonlinear fracture mechanics model ; originally developed for description of crack propagation in concrete, is employed to demonstrate the advantages of non linear fracture mechanics. A testing arrangement is presented with which the comp

We study the nature of the [Ti II] and [Ni II] emission from the so-called strontium filament found in the ejecta of eta Carinae. To this purpose, we employ multilevel models of the Ti II and Ni II systems, which are used to investigate the physical condition of the filament and the excitation mechanisms of the observed lines. For the Ti II ion, for which no atomic data were previously available,

Chronic obstructive pulmonary disease (COPD) is currently the third leading cause of death worldwide and for patients with end-stage disease, the only viable treatment is lung transplantation. In order to meet this clinical need, novel approaches of tissue engineering have emerged. 3D bioprinting technologies are one such rapidly evolving approach and show promising results in terms of biocompatib

Problemformulering: Det ställs alltmer skärpta krav på att förbättra miljö, arbetsmiljö, logistik och ekonomi inom byggproduktion och det krävs därmed att hitta nya metoder som tillmötesgår de nya kraven. Konfektionering har tagits upp som en metod som kan minska byggproduktionens miljöpåverkan och skapa en bättre arbetsmiljö. Om denna metod även kan användas för att effektivisera logistiken och mProblem: In the construction industry there are increasingly higher requirements to reduce the environmental impact and production costs as well as improve the work environment and construction logistics. To meet these new requirements, new production methods are needed. Studies have shown, ready-to-use construction materials can be used in order to improve the environmental impact and the work en

Uppsatsens syfte är att fördjupa förståelsen för den svenska lagstiftarens avvägning mellan personlig integritet och de brottsbekämpande myndigheternas behov av datalagring hos telekommunikationsbolag. Den nationella rätten styrs av EU-rätt på det här området och därför ingår i syftet att redogöra för det nationella och EU-rättsliga regelverket rörande dels datalagring av brottsbekämpande skäl, deThis thesis aims at providing an in-depth study of the balancing act made by the Swedish legislator between the rights to privacy and data protection on the one hand, and the retention of data generated in connection with the provision of publicly available electronic communications networks on the other hand. The latter aspect is something that is made in order to ensure that the data are availab

Starting from the human and societal need to safeguard cultural heritage (CH) in order to connect to past generations’ knowledge and human experience, digital preservation (DP) is a common practice undertaken by cultural heritage organisations (CHOs). DP is heavily relying on the use of information and communication technology (ICT) as the fundamental enabling equipment. However, ICT is coming wit

The purpose of this study was to examine how turning points manifest themselves during the life course of people that have substance abuse. We collected our data through a qualitative method, by reading four autobiographies written by authors who describe in detail how they encountered substances, and how they managed to turn their life around for the better. The chosen material was written in Swe

Water is one of our most valuable resources and polluted water is possibly harmful to both humans and the environment. It is hence of great importance to maintain high quality in drinking water to protect human health. A large number of different contaminants and toxins spread in the environment have the potential to contaminate groundwater. One of these pollutants is arsenic originating from ammu

The Paradox of Employee Engagement and How Managers are Aiming to Control This. Purpose: The aim of this study is to produce new knowledge of the phenomenon of employee engagement from a managerial perspective. More specifically, the authors want to address how managers are navigating the paradox of employee engagement and control; thus, how they are navigating through the challenges of engaging t

This study was carried out in order to identify the main insect species responsible for forest damages (pests) in Sweden, and to explore the relationships between insect outbreaks and environmental variables (temperature, precipitation, and availability of insect host trees, including storm damaged trees). Special attention was given to changes in management practices through time, and their conse
