Importance of vertex corrections for obtaining correct selection rules in the theory of photoemission

It is shown that the commonly used approximation for the no-loss angle-resolved photocurrent from solids in general violates the optical selection rules if the final-state inverse low-energy electron diffraction orbital is taken to be damped. The violations occur in the velocity formula, which is inconsistent with the corresponding and commonly used acceleration formula in which the matrix element

Modelling tool life in the machining of strain-hardening material - Alloy 718

This publication presents a model that describes the lifetime of a tool when used for cutting work in strain-hardened material. The model is known as the Shortcut-Wear-Model (SWM) and can be com-pared with the established model based on Colding equation. The extent of this work has been limited to the turning of the nickel-based alloy 718 with fibre reinforced ceramic cutting tools. This model has

Numerical Study of Cellular Instability in Burner Stabilized Adiabatic Laminar Premixed Flames

The thesis deals with experiments and numerical simulations of adiabatic laminar premixed flames anchored to a heat-flux burner using different mixtures under various operating conditions. The aim is to obtain a better understanding of cellular instability in heat-flux burner anchored flames. Numerical and experimental studies were carried out to characterize the onset and the evolution of cellula

Research methods courses as a mean of developing academic general practice

Since 1989, the authors have given courses in research methodology, and these courses are now given at six venues in southern Sweden, as well as in Denmark. The course corresponds to half a year's full-time study, with half the time devoted to lectures and studies of literature, while the rest is spent on an individual project under supervision. To enable part-time study, the course extends over 1

Remote Boundary-Scan System Test Control for the ATCA Standard

The backplane in a multi-board system has a limited wiring capability, which makes additional backplane Boundary-Scan wiring to link the boards highly costly. The problem is to access the Boundary-Scan tested boards with the Boundary- Scan controller at the central board. In this paper we propose an approach suitable for the Advanced Telecom Computing Architecture standard where we make use of the

Att bära världen på sina axlar : Miljövetares uppfattningar av och förhållningssätt till miljöproblem och sin profession

Popular Abstract in Swedish Avhandlingens syfte är att undersöka blivande och utexaminerade miljövetare uppfattningar av och förhållningssätt till miljöproblem och till sin profession. Professionaliseringen av miljöarbetet kan ses som en process som skedde till följd av en större samhällsförändring där miljöfrågorna tog plats i samhällsdebatten, vilket innebar att allt fler aktörer börjat arbeta mThe aim of the thesis is to investigate experiences of and ways of relating to environmental issues and towards their profession among a group of graduates in environmentla science. The respondents were either in the end of or had completed an educational program in Environmental sciences with a social science perspective offered at Malmö University. Those who hade completed the program have recen

Förundran och förväntan

In nine chapters this book presents the interplay of Christian faith and interreligious relations, with particular focus on creation theology, christology and eschatology. The theological contributions of, e.g., Albert Scheweitzer, Abraham Joshua Heschel, Paul van Buren, John F. Haught, and Krister Stendahl are presented and discussed.
