Etniskt företagande som startmotor: Erfarenheter från somaliska företagare i USA

Det är tio gånger så vanligt att migranter från Somalia startar eget företag i Minnesota, som i Sverige. Sysselsättningsgraden för somaliafödda är också två till tre gånger högre i USA. I rapporten ”Etniskt företagande som startmotor” har ekonomhistorikerna Benny Carlson och Tobias Schölin vid Lunds universitet intervjuat företagare och företrädare för somaliska företagarcenter i Minnesota.

Proton-Induced X-ray Emission Spectroscopy in Elemental Trace Analysis

Using protons in the MeV range as excitation source and a high resolution Si(Li) detector,X-ray emission spectroscopy is shown to be capable of analyzing many elements with Z > 15 simultaneously at the 10-12 g level. This work discusses a theoretical lower limit of detection at moderate proton energies and gives examples of possible applications: analysis of the elemental composition of air-borne

Computational Analysis and Modeling Techniques for Monolithic Membrane Reactors Related to CO2 Free Power Processes

Funded by European Community and Swiss government research project AZEP (Advanced Zero Emission Power Plant), the project was carried out at the Department of Energy Sciences at Lund Faculty of Engineering (LTH). The project addressed the development of a specific, zero emissions, gas turbine-based, power generation process to reduce local and global emissions in a cost-effective way. In this proj

Analysis of Particle Emission During Simulated Processing of Multifilament Fibres

The use of multifilament fibres in composites is increasing. For usability, health effects and comfort it is important to include human aspects already in the development of materials and handling techniques. This paper presents a pilot experiment for designing further experiments on emission of particles and fibres from multifilament fibres during friction, bending and tensile forces.

Treatment of Skin Wounds with Cell Transplantation and Gene Transfer

Popular Abstract in Swedish Sår som inte läker utgör ett betydande problem för dem som drabbas och för sjukvården i stort. Utebliven eller defekt läkning är ofta ett led i en bakomliggande sjukdom som exempelvis diabetes, förlamningstillstånd eller olika bindvävs- och kärlsjukdomar. Förutom en mycket stor ekonomisk belastning för sjukvården, så innebär det ett stort fysiskt och psykiskt lidande föBackground: A large number of different wound coverings have been used in order to improve the wound microenvironment, and thus accelerate repair. Since almost two centuries, clinicians and researchers have developed techniques for skin transplantation. In the past several decades, growth factors have been used as tools for accelerating and modifying skin wound repair. The experimental work in thi

Effects of the Spin-Orbit Interaction on Transport and Optical Properties of III-V Semiconductor Quantum Wells

Effects of the intrinsic electron spin-orbit interaction on transport and optical properties of III-V semiconductor quantum wells have been studied theoretically. It is shown that due to crystal anisotropy of this interaction, the weak localization magnetoresistance in a magnetic field parallel to interfaces is very sensitive to the epitaxy growth direction and also to the orientation of the magn

A psychotherapist haunted by a nonsensical plot [Review of the motion picture Gothika]

Gothika breaks new ground in forensic psychology by implying a new defense: innocent by reason of spirit possession. The film, on its surface, deals with a number of other psychological issues. Its heroine, Dr. Miranda Gray, is a criminal psychologist who works in an institution for the criminally insane. There is discussion of repression as a "survival tool," episodes of apparent psychogenic amne

Risk and Vulnerability Analysis of Interdependent Technical Infrastructures: Addressing Socio-Technical Systems

The society of today is highly dependent on technical infrastructures. Several incidents around the world the last decades have clearly highlighted the major effects technical infrastructure breakdowns have on life, health and economy of society. The vulnerabilities inherent in our technical infrastructures must be addressed in a proactive manner; it is not feasible to wait for major incidents to

Hyperbolic systems with relaxation: symmetrizers and entropies

This paper deals with the Cauchy problem for hyperbolic so-called stiff systems in one space dimension with large relaxation term depending on a small parameter $delta$. In this case the symmetrizer for the modified symbol of the system, in general, depends on the wave number $omega$ and does not define a quadratic entropy. Therefore, the concept of stiff well-posedness of the Cauchy problem appea
