AbstractThe need to minimise wear of hardmetal cutting tool materials requires an understanding of, and in turn accurate measurement of, both the external changes in dimensions and the internal microstructural changes which cause plastic deformation underneath the tool coating.This paper summarises development of methods to quantify the dimensional changes of the complex 3D tip shape of a tool and
The Coulomb excitation experiment to study electromagnetic properties of low-lying states in Ca-42 with a focus on a presumably superdeformed band was performed at the Laboratori Nazionali di Legnaro in Italy using the gamma-ray spectrometer AGATA Demonstrator coupled to the DANTE charged particle detector array. First results are presented, including the refinement of the Ca-42 level scheme.
Electronic structure of free and neutral Rb and K clusters containing from few tens to few hundred atoms has been studied using synchrotron radiation. Core-level photoelectron spectroscopy has been used to probe the metallic nature of Rb and K clusters. We show that the metallicity exists down to the dimensions of few nanometers. Simultaneously the emergence and evolution of the valence band struc
When developing software-intensive products for a market-place it is important for a development organisation to create innovative features for coming releases in order to achieve advantage over competitors. This paper focuses on assessment of innovation capability at team level in relation to the requirements engineering that is taking place before the actual product development projects are deci
Pollination is a key ecosystem service which most often has been studied in isolation although effects of pollination on seed set might depend on, and interact with, other services important for crop production. We tested three competing hypotheses on how insect pollination and pest control might jointly affect seed set: independent, compensatory or synergistic effects. For this, we performed a ca
The chemistry Of HfI4 adsorbed on the Si(100)-(2x1) surface has been studied by core level photoelectron spectroscopy in ultra-high vacuum. Two stable surface intermediates are identified: HfI3 and HfI2, both of which remain upon heating to 690 K. The dissociation of HfI4 is accompanied by the formation of SiI. In addition, HfI4 is Observed up to 300 K. Complete desorption of iodine occurs in the
In this paper we present a precise and reliable measurement of the 1s(2)2p P-2(3/2) lifetime for Li-like Ni. The measurement was done using the technique of beam-foil spectroscopy employing a beam of 5.9 MeV/u Ni from the UNILAC accelerator at GSI. Special attention was taken concerning satellite blending and foil-ageing problems to justify the reliability of the lifetime value extracted from the

The global energy system is still dependent on fossil fuels, but it has become necessary to change this system immediately. In this research, I conduct a case study of the Central Java province in Indonesia to consider how an energy transition can be implemented at the subnational level. I investigate factors influencing the adoption of renewable energy in the province. I use the multi-level persp
Waste management is an important facet of sustainable development, as improper waste disposal will lead to various negative environmental and health impacts. Recycling has been found to be a useful way to manage waste materials and reduce the negative impacts of waste accumulation. In Thailand, attempts to increase recycling are being hindered by lack of public participation. The aim of this study
Möjligheten att visualisera olika sjukdomstillstånd med hjälp av bilder har inom sjukvården blivit mer och mer populärt. Nuklearmedicinska bilder framställs genom att en liten mängd av ett radioaktivt ämne injiceras i patienten och sedan detekteras med hjälp av en gammakamera. Genom att utnyttja olika upptagsmekanismer kan funktionen av ett område eller ett specifikt organ i kroppen undersökas. BlThe purpose of this work is to assess the activity level needed to achieve satisfactory diagnostic information in regional cerebral blood flow single photon emission computed tomography (rCBF SPECT) by introducing a new evaluation method to be used for and hopefully facilitate optimization studies in nuclear medicine in the future. The purpose is further to perform a visual grading study and inves
The purpose of this Master’s thesis is to identify the role of corporate sustainable entrepreneurship in linking sustainability and profitability on the strategy level and how the proactive drive of entrepreneurship can lead to a sustained competitive advantage. In relation, the purpose is to guide the case company towards a profitable inclusion of sustainability into the current strategic plannin
The Bank Lending Channel, proposed by Bernanke & Blinder (1988), among other transmission mechanisms, is hypothesized to exist in China because of the dominance of the Chinese banking system. This paper mainly investigates the effect of monetary policy rate change on the lending behavior of Chinese banks. The study firstly used the aggregated data of all banks including policy banks, commercia
Conclusion: Education, but not occupation, was differentially associated with adult asthma phenotypes in the general population. Further research into socioeconomic status variation in various asthma phenotypes is warranted.
Background: According to the “brain-reserve hypothesis” in Alzheimer’s disease (AD), patients with more years of education are expected to have higher cognitive status during adulthood. Hence, they might have a relatively larger burden of AD pathology and a more advanced level of the disease when dementia is clinically evident. Higher educated people would also be expected to perform better on sta
In this study we compare different volatility models on their ability to forecast one day ahead volatility and value-at-risk (VaR). We compare five different GARCH specifications: GARCH, IGARCH, GJR-GARCH, EGARCH and APARCH, as well as EWMA, each paired with six different conditional distributions. These models are used to forecast volatility and VaR one day ahead using daily return data from the
