By pulse-modulating a cw dye-laser beam and employing the delayed-coincidence technique, we have determined the natural radiative lifetimes of a number of atomic states in rare-earth atoms Eu, Dy, and Yb. In the measurements, which were performed on an atomic beam, exponential decay curves with good statistics were obtained using short measuring times. The general features of the technique are dis

The aim of this degree essay is to analyze the concepts of orders of creation and orders of preservation in the theology of Dietrich Bonhoeffer (1906-1945). I have focused this study on two of Bonhoeffer’s works, namely Creation and Fall (1933) and Ethics (1943). Through my questions I explore the continuities and tensions of Bonhoeffer’s theology over time and in relation to his contemporaries an

Motivated by the fact that exponential and Laplace distributions have rational characteristic functions and are both geometric infinitely divisible (GID), we investigate the latter property in the context of more general probability distributions on the real line with rational characteristic functions of the form P(t)/Q (t), where P(t) = 1 + a(1)it + a(2)(it)(2) and Q (t) = 1 + b(1)it + b(2)(it)(2

Virtual communities, including communities dedicated to consumption practices, were named one of the rising modern trends. With the technological development, nowadays, people do not need actual locations to meet for being friends because multiple blooming social networks allow people to stay connected 24/7 no matter where they are in this world. This technological development has many positive ef

Class I major histocompatibility antigens are composed of a heavy chain that is noncovalently associated with β2-microglobulin (β2m). Most class I molecules are membrane bound, but mouse and rat cDNA clones and genes without a functional code for the transmembrane amino acids have been identified. The membrane-associated class I molecules are important in the control of cell-mediated cytotoxicity,

This paper outlines an innovation-focused design research collaboration that connects New Zealand design and manufacturing industry with advanced design thinking about design for desirability, a research area pursued at AFFECT - the Centre for Affective Design Research at Massey University in Wellington (NZ). Nowadays, it’s all about offering products that are desirable; products need to appeal to

Genetic counselling in Sweden may be traced to the eugenics movementin the early twentieth century. A rudimentary form of what we might call geneticcounselling today was practised within the state governed Medical Board in the1940s and 1950s by the scientific advisor Nils von Hofsten. In the 1950s, Jan ArvidBöök, professor of medical genetics at Uppsala University, realised the importanceof studie

The paper examines whether the changes in the objectives of the EU means a change in the competition acquis. A three step analysis leads to the conclusion that this has not to be expected. Initially the status of competition in the constitutional hierarchy under the old EC Treaty is examined before the detailed changes under the Lisbon Treaty are set out. The paper then investigates whether the am
