This thesis contributes to the ongoing debate about livelihood diversifi cation and the related question of agriculture’s central role in rural development in the Sahel. It focuses on on-farm diversifi cation during the dry season. The aim is to assess the practice and potential of gum arabic production for smallholders in central Sudan. The agricultural system of gum arabic production has provide

Nuclear magnetic resonance (NMR) spectroscopy was used in order to investigate the relationships between structure, dynamics and calcium binding in the intracellular regulatory protein, calmodulin. Calmodulin consists of two similar domains, each binding two calcium ions with positive cooperativity. The studies described in this thesis focus on the isolated C-terminal domain, TR2C, and two mutants

Due to erosion a quite specially shaped site was formed in the Cederberg, Western Cape, South Africa, as a rock with a hollow base large enough for rooming an occupation layer dated to the Middle Stone Age. The occupation layer holds a number of so called Stillbay points that appear at about the time when the first decorations and ornaments are documented. This might indicate a mental improvement

Boken är ett urval av papers varav de flesta presenterades vid ESSSATs (European Society for the Study of Science and Theology) konferens i Lyon våren 2000. Bidragen belyser följande teman: Varieties of Design and Order, The Problem of Causality in Science & Theology, Methodology in Science & Theology, och Science and Religion in Culture.

This State-of-the-art report in the CREDIT project has identified and examined a number of existing sets of performance indicators, methods and tools for understanding user needs, requirement management, databases and mandatory reporting. The report has also focused on approaches to better benchmarking schemes in the Nordic and Baltic countries that can compare end-user and client needs, and perfo

The ethical dimensions of Swedish archaeology will be discussed from several angles – those of the archaeology of the past, critical archaeology, contemplative archaeology, and antiquarian archaeology. These themes overlap in the various fields of archaeology. In my opinion ethical perspectives on archaeological practice are vital for the survival and legitimacy of archaeology. Thus, archaeologist

Introduction to the edition of the unfinished doctoral dissertation "Magisk cirkel" by David Aquilon (1965 - 1999), focusing on the films of Ingmar Bergman and expecially "The Serpent's Egg" (1977).

This dissertation about the utilization of applied social science is based on studies of research use in three different policy sectors - the social service, the building, and the working life sectors. In these studies some characteristics of the different policy sectors, like the distribution and exercise of power and control, was found to play a fundamental role in forming the patterns of resear

At present, relatively little is known about the relationship between bank credit allocation and economic growth. It seems clear that the structural characteristics of the banking system are significant factors influencing long-run allocation of credit across real sectors of the economy as well as across financial institutions. The purpose of this study is to examine the relationship between chang

Tid och envishet är viktiga faktorer för att lyckas med innovation. Om detta och andra faktorer står att läsa i denna bok. Boken är född ur ett inspirerande, lärorikt år inom ramen för forskningsprogrammet PIEp: Product Innovation Engineering program. Ett år då vi forskare mött nya människor, nya företag, fått nya insikter, men också en bekräftelse på att svenskt näringsliv tycks göra allt för att

An LTE-enabled smartphone is a software-defined radio system that must cover a large number of frequency bands with different duplex differences. A proposed adaptive wideband duplexer needs a circulator to create the required initial isolation. To replace this an LC-based tunable low-isolation device is presented in this paper, providing the required tuning range for LTE Band I, II, III and VII. T
