Gifts have been given and received in all eras and societies; gifts are part of a universal human exchange. The importance of creating and sustaining social bonds with the help of gifts is widely acknowledged by social scientists, not only from anthropological but also from economic, sociological, and political science perspectives. Contemporary anti-corruption campaigns, however, have gifts to be

A heavy-duty diesel engine operating case producing no engine-out smoke was studied using combined simultaneous optical diagnostics. The case was close to a typical low-load modern diesel operating point without EGR. Parallels were drawn to the conceptual model by Dec and results from high-pressure combustion vessels. Optical results revealed that no soot was present in the upstream part of the je

The aim of this study was to find sorption filters with a capacity to remove heavy metals from landfill leachate. Initially a batch test was performed with granular activated carbon, CAP meal derived from animal bones, iron fines, a non-metallic part of bottom ash from a municipal solid waste incineration plant, metal residues from the same bottom ash, lime stone and peat. Activated carbon, CAP me

The hunter-gatherer groups of Southeast Asia represent a diverse range of adaptations. The so-called Negritos of the Andaman Islands, the Malay Peninsula and the Philippines have attracted particular attention because of long-standing claims that they represent traces of pre-agricultural Southeast Asia. Research on Andaman and Philippine prehistory has tended to maintain at least some components o

This thesis investigates structure-acoustic problems, which involve a flexible structure coupled to an enclosed acoustic fluid. In the literature, this type of problem is usually referred to as vibroacoustic problems or structure-acoustic problems with fluid interaction. The thesis consists of two parts. The first part provides an introduction into the field of structure-acoustic analysis withi

Within the Eriksonian identity tradition, exploration of different life domains is crucial to identity formation. This is a process supposed to start during adolescence and develop in a social context. Most of the adopted children in Sweden, now in adolescence, are adopted from countries outside of Europe, which means that they neither share their biological nor ethnical roots with their adoptive

The mechanical stress build up in fibre handling, the dynamical frictional phenomena between fibres and curved surfaces and formation of dust have been studied. Typical are stick slip behavior and threshold stress levels for formation of dust. The emission of dust can be limited by electrostatic charging. The measured coefficients of friction of the fibres depend on the mechanical properties, micr

Fast and reliable time and frequency synchronization is crucial for packet-based orthogonal frequency division multiplex (OFDM) systems. In this paper we compare and analyze preambles for OFDM systems based on repeated OFDM data symbols or repeated short pseudonoise sequences (PN-sequences). We make an analytical evaluation for AWGN channels and simulate the performance in oneand two-tap Rayleigh

I give an overview of the calculations done in three-flavour Chiral perturbation theory at next-to-next-to-leading order with an emphasis on those relevant for an improvement in the accuracy of the measurement of Vus. It is pointed out that all needed low energy constants can be obtained from experiment via the scalar form-factor in Kl3 decays

The clean development mechanism (CDM), outlined in Article 12 of the Kyoto Protocol (UNFCCC 1997) is one of the most debated and disputed provisions of the current climate regime. Developing and developed states, business as well as environmental NGOs all seem to be dissatisfied with the mechanism in its current shape, and a reform of the CDM is therefore high on the agenda of the climate negotiat

This article outlines a numerical study on the benefit of using High-Performance/Strength Concrete for fabrication of concrete elements. For this purpose a comparison is done between the cost of existing beams with normal strength concrete and optimized beams made of High-Performance/Strength Concrete. A background is given concerning the most essential properties of High-Performance/Strength Conc

Liturgical reform is rampant today. The liturgical movement of the twentieth century has been succeeded by a period of uninformed tinkering with the liturgy by individual priests and ministers. The article identifies and criticizes five possible reasons for reforming (or simply changing) the liturgy.

To promote industrial development and economic growth is a vital issue for governments all over the world. The ideals guiding policymakers in their endeavours, strongly influenced by traditional economics and the innovation system approach, are that innovations based on new and advanced knowledge are central for industrial and economic development. As is exemplified through the quote below policym

Hans Christian Andersen's tale "The Marsh King's Daughter" (1858) is analysed in relation to Birgitta Trotzig's prose tale of the same title, Dykungens dotter (1985), with the emphasis on Andersen's tale which would seem to be a pious Christian morality in which evil is destroyed and the powers of light conquer darkness. At the same time, Andersen's symbols make clear that darkness is a necessary
