Popular Abstract in Swedish Om ljuspartiklar (fotoner) uppnår tillräcklig hög energi kan dessa omvandlas till ett partikel- anti-partikel par under en kort tidsrymd. Det är då möjligt får två sådana fotoner att kollidera och det går då studera ljusets struktur. I denna avhandling studeras kollisioner där ljuset har fluktuerat till hadronsk materia och där hela kinematiken i två-foton kollisionen äThis thesis is mainly an analysis of data taken by the VSAT detector in the DELPHI experiment at the LEP II collider at CERN. The analysis spans from 1998 to 2000, with a center of mass energy ranging from 189 to 206 GeV. The VSAT calorimeter was constructed to be a luminosity and background monitor for the DELPHI experiment, and a full description of the luminosity and background analysis for the

We report on a summary of fabricating and characterizing nanoscaled ferromagnetic single-electron transistors (F-SETs). One type of device is assembled with an atomic force microscope. A single 30 nm Au disc, forming the central island of the transistor, is manipulated with Angstrom precision into the gap between plasma oxidized Ni source and drain electrodes which are designed with different geom

This book chapter problematizes the concept of 'honor killings' by using the assassination of Fadime Sahindal in Sweden in 2002 as an example of violence against women.

Speckle is an unwanted noise in ultrasound images, and appears as returning echoes are coherently summed over the transducer surface. In Doppler applications, the total power of the received spectrum varies in a manner similar to speckle. This paper investigates the correlation of continuous-wave (CW) Doppler signals obtained from simultaneously transmitted carrier frequencies, when a slowly flowi

Geomechanical simulation of the evolution of a geological structure can play an important role in predicting open fracture development for all stages in that structure's development. In this work, three such geomechanical simulations are used to predict the evolving stress and strain fields, including dilational and compactional changes in the rock fabric in developing fault and fold systems. Thei

This chapter presents a brief review of studies on swirling and non-swirling impinging jets. Also, a numerical investigation of heat transfer from impinging swirling jets is described. Various turbulence models are used. Comparison with experimental data is provided. Generally, the V2f model was found to perform better than other models, but for small nozzle-to-plate distances, it was hard to main

Description: It is stated that even though plentiful of studies over the last decades have been concerned with internationalization in/of higher education, it has not been from the perspectives from the teachers and students and their experiences of aspects of internationalization in relation to their educational context (that is, as a student, and as a teacher). To emphasize the quality dimension

The predominant protein in human semen, semenogelin, was characterized by lambda gt11 clones isolated from a seminal vesicular cDNA library. One clone, carrying a cDNA insert of 1606 nucleotides and a polyadenylated tail, coded for the entire semenogelin precursor. An open reading frame of 1386 nucleotides encodes a signal peptide and the mature protein of 439 amino acid residues, in which residue

Gift-for-sex (GFS) barters are a niche practice potentially representing the commodification of everyday dating practices. We inquire how GFS exchanges are practiced and understood in contemporary Russia. Second, we situate these in relation to contemporary economic culture. Our project provides answers in two steps based on online content. First, we identify GFS exchange practices within a major

In this paper, we introduce a method to use written natural language instructions to program assembly tasks for industrial robots. In our application, we used a state-of-the-art semantic and syntactic parser together with semantically rich world and skill descriptions to create highlevel symbolic task sequences. From these sequences, we generated executable code for both virtual and physical robot
