This thesis presents the developement and verification of cutting force models for multi-toothed cutting processes. The scope of the thesis includes the modelling and measuring of factors that affect the mechanical load variation between individual cutting edges in the process. These factors will for example influence tool life and workpiece quality. The most important factors are; errors in radia

Smooth muscle cell (SMC)-specific deletion of transforming growth factor beta (TGF-beta) signaling would help elucidate the mechanisms through which TGF-beta signaling contributes to vascular development and disease. We attempted to generate mice with SMC-specific deletion of TGF-beta signaling by mating mice with a conditional ("floxed") allele for the type 11 TGF-beta receptor (tgfbr2(flox)) to

Objective The effect of salt restriction on blood pressure is under intense debate. We tested the effect of 100 mmol salt reduction on ambulatory blood pressure (ABP) in 46 Swedish individuals, 39 of whom completed the study, using a double-blind, placebo-controlled, crossover design. Furthermore, we tested whether the basal plasma concentration of renin or N-terminal atrial natriuretic peptide (N

Objectives: At the request of the European Commission and in the framework of the European Machinery Directive, research was performed in five different laboratories to develop specifications for surface temperature limit values for the short-term accidental touching of the fingertip with cold surfaces. Methods: Data were collected in four laboratories with a total of 20 males and 20 females perfo

This study was directed towards personality-related, value system and sociodemographic variables of nursing students in a situation of change, using a longitudinal perspective to measure their improvement in principle-based moral judgement (Kohlberg; Rest) as possible predictors of stress. Three subgroups of students were included from the commencement of the first three-year academic nursing prog

Abstract Background: Empowerment is essential in the rehabilitation process for people with psychiatric disabilities and knowledge about factors that may play a key role within this process would be valuable for further development of the day centre services. Objective: The present study investigates day centre attendees' perceptions of empowerment. The aim was to investigate which factors show th

Montmorillonite is a key ingredient in a number of technical applications. However, little is known regarding the microstructure and the forces between silicate platelets. The size of montmorillonite platelets from different natural sources can vary significantly. This has an influence on their swelling behavior in water as well as in salt solutions, particularly when tactoid formation occurs, tha

The two major forms of the amyloid-beta (Aβ) peptide found in plaques in patients suffering from Alzheimer's disease, Aβ40 and Aβ42, only differ by two amino acids in the C-terminal region, yet they display markedly different aggregation behavior. The origins of these differences have remained challenging to connect to specific molecular-level processes underlying the aggregation reaction. In this

We present a method to fabricate nanometer scale gaps within InAs nanowires by selectively etching InAs/InP heterostructure nanowires. We used vapor-liquid-solid grown InAs nanowires with embedded InP segments of 10-60 nm length and developed an etching recipe to selectively remove the InP segment. A photo-assisted wet etching process in a mixture of acetic acid and hydrobromic acid gave high sele

The problem addressed in this thesis is how to account for environmental aspects when purchasing freight transports. This problem is addressed from a transport purchasing perspective. The result of the research is a model for how transport purchasers can incorporate environmental aspects when purchasing freight transports. This mode! is built on two tools and a work process. The first too! is a st

There is a rhetoric in current European political agenda for widening access to ICT’s as part of a strategy for encouraging greater participation in public life. We argue against a naïve assumption that technology in itself could provide solutions. Knowing that systems with potential for meaningful use are available is a necessary, but not sufficient, condition to bring about desire for use in any

The nature of scientific research and the development of scientific software have similarities with processes that follow the agile manifesto: responsiveness to change and collaboration are of the utmost importance. But how well do current scientific software development processes match the practices found in agile development methods, and what are the effects of using agile practices in such proc

Popular Abstract in Swedish Ekonomistyrsystemens utformning och roll är sedan 1980-talet föremål för stor uppmärksamhet mot bakgrund av pågående förändringar i företagens tillverknings- och marknadsmiljö. En grundläggande frågeställning som behandlas i boken är vilken påverkan företagens situation har på ekonomistyrsystemets utformning och om olika ekonomistyrsystem är mer ändamålsenliga än andra The focus of the thesis is the situation of and the management control systems in middle-sized, manufacturing companies. We have examined the relevance of different types of management control systems for different situations and formulated taxonomies of the contingency factors environment, production situation and business strategy. We found two types of situation. The first type, the interactive

This doctoral thesis examines early medieval Slavic migration to the island of Bornholm (Denmark). With a combination of interdisciplinary theories and approaches, which focus on human translocation and memory and identity construction, a holistic approach to the studies of migration in archaeology is proposed. It is argued that in order to address cases of migration it is necessary to consider th

Syfte: Studiens syfte är att undersöka om det i teorin beskrivs faktorer inom hur man framgångsrikt kommunicerar en förändringsprocess som inte appliceras i praktiken, vilket i så fall kan ligga till grund för att en så stor del av förändringsprocesser inte implementeras. Metod: En kvalitativ tvärsnittsstudie utifrån en deduktiv ansats. Uppsatsens empiriska material insamlades genom semistrukturerObjective: The objective of this dissertation is to investigate whether relevant theory describes certain elements that facilitates communicating a change process successfully, which are not applied in practice and could thus constitute for the large amount of change processes that are never implemented. Method: A cross-sectional study with a deductive and qualitative approach. The dissertations’
