High-resolution study of the C-12(gamma,p gamma')B-11 reaction using a HpGe detector to resolve excited states of B-11 through the observation of their gamma-ray decays

Relative populations of states in 11B following the 12C(,p)11B reaction have been measured with high resolution using a 70% HpGe detector to observe decay rays from the residual nucleus. The triplet of states near 7 MeV in 11B are resolved and the measured populations compared to previous data. The analysis includes a consideration of -proton angular correlations, which was not made in the previou

The Politics of Publishing : Freedom of the Press in Denmark 1770-1773

Sweden and Denmark-Norway experienced a degree of freedom of the press at the beginning aof the 1770s that was quite unusual compared with much of continental Europe. The liberty of the press quickly changed the system of communication and the artickle explores how a new culture of communication was established in Denmark and who appropriated the written word and how and why.

Analyses of Spur and Helical Gears

The thesis contains three papers that comprise studies of the dynamic behaviour of involute spur and helical gears, and one paper that describes a method to determine the influence of misalignment on the static helical gear tooth stress. In the first study, the influence of the contact ratio on the dynamic response of a spur gear was examined. The spur gear pair was modelled using a single degree

Response-Time Control of a Processor-Sharing System Using Virtualized Server Environments

Feedback in server systems has during last years gained much interest in order to fulfill still increasing demands on performance and optimization regarding, for example, quality of service (QoS) requirements. In this paper we expand a previously published feedback–based prediction scheme for controlling a single server queue together with a new control strategy. These control structures have the

A breakthrough for coated glazing in Sweden. Will double-pane windows take over the market?

Ever since the end of the 1970s triple-pane windows have been ”standard” in new construction of dwellings and non-residential premises in Sweden. The background was the first oil crisis in 1973, which led to a dramatic sharpening of the thermal requirements regarding the thermal envelope of Swedish buildings. These were introduced in the new building code SBN 75 which was brought into practice in

Desalination and Economy Prospects as Water Supply Methods

This paper discusses five major parameters in desalination, namely technology, raw-water, energy sources, cost and environmental effects. Both size and yield have grown rapidly in desalination plants due to high performance in technology developments in the last few years. Five different types of desalination technology are presented and bench-marked for long-term use: multistage flash evaporation
