The purpose of this project is studying heat transfer to indexable cutting tools during milling of a selection of titanium alloys, relevant to the industry. To achieve this goal, both experimental and theoretical models were contemplated to formulate the current thesis. The experimental set-up was designed and executed at Seco Tools AB, supporting the project as industrial collaborator. The therm
Forests form the backbone of the European terrestrial carbon sink (State Forest Service & Ministry of Environment, 2018). As the European Union (EU) strives to become climate neutral by 2050, forests are accounted for the natural carbon absorption mechanism (European Commission, n.d.). Currently, the European net land carbon sink is decreasing largely due to forest ageing (Pilli et al., 2022),
Syftet med denna studien var att undersöka om porrkonsumtion och traditionella maskulina normer predicerar kvinnoobjektifiering. Studien ämnade att bidra med kunskap och psykologisk forskning om effekterna av pornografi eftersom pornografins roll i samhället är större än de senaste decennierna och relativt outforskad. Datainsamlingen producerades genom en digital enkätundersökning som besvarades aThe aim of this study was to examine if pornographic consumption and traditional masculine norms can predict the objectification of women. Furthermore, the purpose of exploring the subject of the study was to contribute with knowledge and psychological research about the effects of pornography as pornography’s’ role in contemporary society is greater than in recent decades and relatively unexplore
The Women, Peace and Security agenda (WPS) argues for women’s rights and recognition of women’s situations in all stages of a conflict. Previous research has shown how refugee women seem to be overlooked in international legislation. Existing research considering the WPS agenda has mainly focused on issues of implementation and discourses. This study aims to explore how conceptualizations of secur
Radiotherapy is commonly used for cancer treatment, given to approximately half of all cancer patients in Sweden. Despite its widespread usage, there is currently no non-invasive and reliable imaging method that can identify regions of radiation resistance. These regions may be identified by hypoxia, given that radiobiological research has demonstrated a significant correlation between oxygen leve
Trends show a decline in democracy in the CEE region which has mostly been analyzed through the democratic backsliding paradigm. However, recent scholars have proposed another perspective for this trend, the careening paradigm. This paper examines the contemporary democratic development from 2018 to 2023 in the Visegrád Four to explain which theoretical perspective is the most suitable to describe
Attention is drawn to some of the limitations of conventional plume theory, some differences between axi-symmetric and line plumes, and some rationalisation which is possible in correlating data for the flow from wide vertical openings. The paper is more a summary and a series of notes than a lengthy exercise in the subject.
Multispecies sex pheromone trapping (trapping of more than one species in the same trap) for the pine shoot moth Rhyacionia buoliana , the pine moth, Dendrolimus pini , the nun moth, Lymantria monacha , the pine beauty moth, Panolis flammea and the pine sawflies Diprion pini and Neodiprion sertifer was evaluated. The catch from traps baited with the pheromone of a single species was compared with
The longitudinal spread zone was investigated for 30 arctic shorebird populations from 10 different wintering communities in widely different regions of both the Northern and Southern Hemispheres. Information about total breeding and wintering ranges, migratory connectivity and subspecies was compiled from literature sources. The spread of the distributions was analysed in relation to the mean dis
Objectives To obtain reference data representative of normal findings at anal endosonography in pregnant and non-pregnant women. To determine intraobserver and interobserver agreement in the detection of endosonographic anal sphincter defects in asymptomatic women. Methods Twenty-five non-pregnant nulliparous women and 25 non-pregnant parous women (age range, 20-67 years) and 47 pregnant women (a
The project is a part of the research programme "Timber constructions and fire" and has been financed by funds from the Swedish Fire Research Board. The aim of the project is to illustrate the possibility of calculating the fire resistance of building panels and wall constructions. The work has been planned in consultation with the steering group "Timber construction and fire" of the Swedish Fire
[NiFe] hydrogenases catalyse the reaction H2 <-> 2H(+) + 2e(-). Several states of the enzyme have been observed by spectroscopic methods. Among these, the two most oxidized states, called the unready Ni-A and Ni-SU states, have been especially intriguing, because they take a much longer time to activate than the corresponding ready Ni-B and Ni-SI states. It has recently been suggested that the unr
This thesis deals with the development of simultaneous saccharification and fermentation (SSF) in order to improve the economy of the softwood-to-ethanol process. The effect of process stream recirculation on ethanol production from steam-pretreated softwood based on SSF was investigated for two process cases. In the first case, part of the stillage stream after distillation was recycled and in th
PURPOSE: In an experimental study in rats a correlation between nutritional status and hepatic attenuation in CT and signal intensities in MR imaging was shown. Is physiological nutritional status of importance in clinical CT and MR imaging? MATERIAL AND METHODS: In a cross-over study including 12 healthy volunteers (6 women and 6 men, mean age 34 years), CT and MR imaging of the liver were perfor
In this study the effect of strontium substitution on the hydrolysis of alpha-tricalcium phosphate (alpha-TCP) toward the formation of calcium deficient hydroxyapatite (CDHA) was investigated. For that purpose substituted alpha-TCP powders with 1, 5 and 10 mol% Sr substitution for Ca were synthesized by reacting at 1500 degrees C stoichiometric amounts of CaCO3, SrCO3, and Ca2P2O7, followed by rap
