The nature of light and its interaction with matter

This chapter provides a physical background to the following ones. It describes the particle and wave properties of light and the diffraction, polarization, refraction, reflection, and absorption of light and statistics of photon emission and absorption. Planck’s law of heat radiation is described in various mathematical and graphical ways. One section is devoted to a simplified description of the

A distributed Tier-1

The Tier-1 facility operated by the Nordic DataGrid Facility (NDGF) differs significantly from other Tier-1s in several aspects: firstly, it is not located at one or a few premises, but instead is distributed throughout the Nordic countries; secondly, it is not under the governance of a single organization but instead is a meta-center built of resources under the control of a number of different n

Forgetting Anticipation: the double gap between knowledge, policy and practice of risk assessment in Botswana and Tanzania

A society’s ability to anticipate disaster is a fundamental part of its resilience. The purpose of this paper is to investigate potential gaps between theory, policy and practice concerning functions for risk assessment in the governmental systems of southern African development countries, particularly Botswana and Tanzania. It applies comparative case studies with data collected in focus groups a

Themes and challenges in developing sustainable supply chains

Sustainable development is one of the greatest global challenges facing human beings in the 21st century. In order to tackle sustainability related problems, several global, European, and national targets for 2050 have been set. The transition of supply chains activities towards sustainability targets calls for designing new strategies and continuously identifying and tackling the challenges that

Om socialism, feminism och multisolidaritet

This publication deals withe the tensions between socialist and feminist theories and political practices. Multisolidarity is offered as a solution to this idelogical, theoretical and political conflict.

Findability through Traceability - A Realistic Application of Candidate Trace Links?

Since software development is of a dynamic nature, the impact analysis is an inevitable work task. Traceability is known as one factor that supports this task, and several researchers have proposed traceability recovery tools to propose trace links in an existing system. However, these semi-automatic tools have not yet proven useful in industrial applications. Based on an established automation mo

Dispersion Relations in Scattering and Antenna Problems

This dissertation deals with physical bounds on scattering and absorption of acoustic and electromagnetic waves. A general dispersion relation or sum rule for the extinction cross section of such waves is derived from the holomorphic properties of the scattering amplitude in the forward direction. The derivation is based on the forward scattering theorem via certain Herglotz functions and their as

Hankel-norm based interaction measure for input-output pairing

In this paper a new interaction measure for stable multivariablesystems is introduced.The interaction measure, the Hankel Interaction Index,is a dynamic extension of the underlying idea in the classicRelative Gain Array (RGA) and its various extensions. The new index isbased upon the Hankel normof the SISO elementary subsystems built from the original MIMOsystem. The main advantage of the Hankel I

Immunohistochemical study of rats receiving peripheral immunization with IFNg transfected glioma cells

Popular Abstract in Swedish Vi har studerat hur man kan använda immunsystemet för att behandla råttor med hjärntumör (maligna gliom). Eftersom råttor väldigt sällan utvecklar hjärntumörer, så måste vi injicera tumörceller i hjärnan själva. Om djuren inte får någon behandling dör de vanligen inom ca. 24 dagar. Får de däremot en injektion i buken eller under huden på benet med genmanipulerade tumörcMalignant glioma is, with rare exceptions in younger adults, an uncurable brain tumor, as very few survive more than 1-2 years after diagnosis. Despite advances in recent years, current treatments such as surgery, radiotherapy and chemotherapy only prolongs the life of the patients. Because of the poor prognosis, several additional therapies have been investigated and are under development, such a

Aspects on the Regio and Stereo Selectivity in the Hydrolsilylation of 1,3-Dienes

Popular Abstract in Swedish Hydrosilyleringsreaktionen är formellt en addition av en hydrosilan till ett omättat system. Reaktionen är oftast katalyserad av en övergångsmetall, och i denna process är det möjligt att påverka på vilket sätt additionen sker. Denna avhandling är en sammanfattning av fyra artiklar som behandlar regio-, stereo- och kemoselektivitet vid addition av hydrosilaner till konjThis thesis is a summary of four papers concerning various aspects on the transition metal catalysed hydrosilylation of 1,3-dienes. The hydrosilylation reaction is formally an addition of a hydrosilane to an unsaturated system and depending on the reaction conditions, control of stereo-, regio-, and chemo-selectivity can be achieved. Optically active heterobidentate P,N ligands were synthesised f
