Ti (C, N) based cermet materials are predominantly used in continuous finishing applications of metal cutting due to their high hardness, excellent resistance to oxidation and high chemical stability. However, their application in interrupted cutting like milling are limited due to their brittle-like failure due to low fracture toughness. In this work, alternative binder systems such as Co-Ni and
Background Large, international cohort studies generate high-level evidence, but are resource intense. In end-of-life care such studies are scarce. Hence, planning for future studies in terms of data on screening, recruitment, retention and survival remains a challenge. Objectives The aim was to describe recruitment, follow-up and survival in a multinational study of patients’ and relatives’ expec
Group A Streptococcus (GAS; Streptococcus pyogenes) is an important bacterial pathogen causing over 700 million superficial infections and around 500.000 deaths due to invasive disease or severe post-infection sequelae yearly. In spite of this major impact on society, there is currently no vaccine available against this bacterium. GAS strains can be separated into >250 distinct emm (M)-types, and
Using molten salts for etching aluminum (Al) away from the MAX phase for MXene synthesis is an attractive alternative method that allows one to avoid the use of toxic hydrofluoric acid (HF) solutions. However, the mechanism of the MAX phase reaction with molten salts remains to date unclear due to the lack of in situ data. Here, we present a detailed in situ time-resolved synchrotron radiation X-r
During the evolution of parasites, co-speciation and host-range expansion are thought to play roles in establishing associations with hosts, while sorting events can lead to dissolution of those associations. To address the roles of these processes, we focus on avian haemosporidian parasites infecting hosts of the intensively studied great tit species complex. We estimated the phylogeography of li
Although cities globally are increasingly mobilizing re-naturing projects to address diverse urban socio-environmental and health challenges, there is mounting evidence that these interventions may also be linked to the phenomenon known as green gentrification. However, to date the empirical evidence on the relationship between greenspaces and gentrification regarding associations with different g
Population ageing within Europe has major social and economic consequences. One of the most devastating conditions that predominantly affects older people is dementia. The SMART4MD (Support Monitoring and Reminder Technology for Mild Dementia) project aims to develop and test a health application specifically designed for people with mild dementia. The aim of this feasibility study was to evaluate
Measurements of the differential production cross-sections of prompt and non-prompt J/ψ and ψ(2S) mesons with transverse momenta between 8 and 360 GeV and rapidity in the range |y|
A statistical analysis of amplitudes corresponding to multipath components in outdoor (urban/suburban) channels is presented. The study is based on short-term complex impulse response measurements conducted in Stockholm at 1.88 GHz carrier frequency with 5 MHz bandwidth. The actual investigations show that the Rice distribution gives the best fitting in the Kramer-von-Mises sense. Further it is sh
Using the level crossing technique with parallel magnetic and electric fields the tensor polarizability of the 7 p 2 P 3/2 level in Rb 87 and the 8 p 2 P 3/2 level in Cs 133 was measured with the results α 2 (7 p 2 P 3/2 Rb 87 ) = -3.2 (2) MHz (kV/cm) 2 and α 2 (8 p 2 P 3/2 Rb 133 ) = -7.6 (3) MHz (kV/cm) 2 Theoretical values, calculated with the Coulomb approximation of Bates and Damgaard, agre
The delineation and characterization of fracturing is important in the successful exploitation of many hydrocarbon reservoirs. Such fracturing often occurs in preferentially aligned sets; if the fractures are of subseismic scale, this may result in seismic anisotropy. Thus, measurements of anisotropy from seismic data may be used to delineate fracture patterns and investigate their properties. Her
The European Union (EU) in its current shape and form is primarily a product of deepening economic integration, whereas a social dimension of European integration that would be comparable in ambition to its economic dimension has failed to manifest itself despite repeated attempts to give the social dimension greater weight. Based on a neo-Gramscian theoretical perspective of hegemony, this can be
Popular summary Guld är en ädelmetall som är mycket älskad av människan och har varit eftertraktad under århundraden. Guld har används som betalningsmedel, som värdebeständig tillgång och som smycken. Men guld har även andra egenskaper som kan vara till stor nytta för människan. En av egenskaperna undersöktes i det här projektet. Guld kan nämligen kopplas till en molekyl och på så sätt få egenskapGold is a transition metal that can be use as catalyst in a various reactions, when coordinated to ligands. In this study two dinuclear gold(I) complexes bearing chiral ligands have been synthesized and tested as catalyst for asymmetric hydrogenation of α,β-unsaturated carboxylic acids. Asymmetric synthesis is also known as enantioselective synthesis and is a very important synthesis method in dru
The main purpose of this thesis report is to examine the theory of ecosystems within the mobile industry and to create a framework that makes it possible to comprehend and manage the value creation in a practical setting. The theoretical part is characterized by mobile ecosystems since they are considered as a fast pace sector where new innovations are ruling the market. Due to these circumstance
The Great East Japan earthquake and tsunami hit coastal cities in Iwate, Miyagi and Fukushima Prefectures of Tohoku Region devastating the energy supply system in the region. Following electricity outage and fuel shortages caused severe problems in the city of Kamaishi varying from lack of mobility, communication, heating to reduced health conditions. It is important to build resilience of commun
Avancerad användning av glas som konstruktionsmaterial i pelare och balkar har blivit allt vanligare de senaste åren. Detta arbete redogör för vilka metoder och normer som kan användas för att dimensionera glasbalkar i bärande konstruktioner och vilken typ av glasbalk som är lämpligast ur hållfasthets och säkerhets synpunkt. Tidigare har glaset mest använts i fönster där det inte har haft en bäran
