Beskrivning och analys av spex (särskilt de lundensiska) som litterär-scenisk genre.

Första delen av en biografisk skildring av Jacob "Svasse" Bergqvist (1887-1959), jur kand vid Lunds universitet, statstjänsteman och revyförfattare.

Glomalin-related soil protein (GRSP) is known as an important microbial by-product which is crucial for preserving or accumulating soil organic carbon (SOC). However, the underlying mechanisms are not well understood. In this study, we investigated the chemical structures of GRSP and its relationship with SOC using 13C nuclear magnetic resonance (NMR) in three tropical forests. The three forests,

Managing entrepreneurship is of importance for the society, for organizations and for the individual. It is not enough with knowledge and skills relating to the idea behind entrepreneurship. The entrepreneur must have knowledge and skills to manage the entrepreneurial process. The purpose of this paper is to put forward for agile project management as an appropriate way to manage an entrepreneuria

In this paper we are investigating how project complexity is affecting the management of single projects in a multi-project environment. The project manager’s perspective is applied. A conceptual framework is developed in order to summarize how project complexity effect project management. The framework is applied to two cases and conclusions are drawn.

BACKGROUND: Aquaporins (AQPs) are integral membrane proteins that facilitate transport of water and/or other small neutral solutes across membranes in all forms of life. The X Intrinsic Proteins (XIPs) are the most recently recognized and the least characterized aquaporin subfamily in higher plants. XIP1s have been shown to be impermeable to water but permeable to boric acid, glycerol, hydrogen pe

Project costing is an area where more research is needed. Beginning from typical project characteristics discusses the specific costing problems of the project. The focus is on how those problems can be managed using activity-based costing. The article also takes up a short discussion about the critical moments of the project costing.

We present an approach towards four dimensional (4d) movies of materials, showing dynamic processes within the entire 3d structure. The method is based on tomographic reconstruction on dynamically curved paths using a motion model estimated by optical flow techniques, considerably reducing the typical motion artefacts of dynamic tomography. At the same time we exploit x-ray phase contrast based on

Metallic cast components inevitably contain defects such as shrinkage cavities which are inherent to the solidification process. Those defects are known to significantly alter the fatigue life of components. Yet very little is known, quantitatively, on the dangerosity of internal casting defects compared to surface ones. In this study, fatigue specimens containing controlled internal defects (shri

Water drainage from porous media is a highly dynamic process often marked by rapid piston-like air invasion events at the front and other rapid interfacial reconfigurations. Liquid phase entrapped behind the moving front drains at significantly slower rates often via gravity driven flow through corners and crevices. This distribution of slowly draining residual water phase determines the plant ava

Series of fast synchrotron X-ray tomographies are taken continuously at a rate of up to 5Hz, while aluminium alloy precursors are foamed in an X-ray transparent setup for several minutes using infra-red (IR) lasers for heating. The entire foaming process from the solid precursor to the expanded liquid foam is captured. The analysis of the sequence of tomographies is done with an emphasis on nuclea

Ductile failure of three 6xxx serie aluminium alloys has been characterized and modelled for about thirty hardening conditions each. These alloys involve relatively similar composition and volume fraction of second phase particles. The tensile mechanical properties show the expected decrease of fracture strain with increasing strength but also major differences among the different alloys with a fa

The complexity of microwave heating stems to a large extent from the intrinsic complexity of the materials exposed to microwave irradiation. For simple ideal homogeneous material, its size, shape and orientation with respect to the electromagnetic field influence the microwave absorption properties at the macroscopic scale. Furthermore, a number of material parameters, namely the complex permittiv
