Despite the fact of being considered as one of the safest regions in the world, the EU reports a wide number of cases of human trafficking every year in its Member States. Moreover, free movement of persons that EU membership grants makes it easier for human trafficking criminals to transport and exploit victims within Member States. The country that has shown by far to have the largest number of
A light pulse that travels through a narrow spectral window, i.e. a frequency range of low absorption, within a strongly absorbing frequency range will be delayed due to strong dispersion. If however, the absorbing structure is inverted, such that it is amplifying instead, one will see that a pulse travelling through this window will have its pulse peak come out of the material before it is sent i
Packaging-free grocery shopping enables consumers to avoid single-use packaging and buy specific quantities tailored to their needs. Despite its benefits, it faces challenges such as limited product variety and availability. This qualitative study explores the motivations, behaviors, and strategies of individuals who engage in or discontinue packaging-free shopping, including how they combine pack
The free volume and crystallization behaviour of poly(ethylene naphthalate) (PEN) treated in pressurized carbon dioxide was studied, using Positron Annihilation Lifetime Spectroscopy (PALS) and Differential Scanning Calorimetry (DSC). PALS probes the values of free volume cavity sizes in materials, thus making it possible to investigate the effect of pressurized carbon dioxide treatment on free vo
Polarization deficiency and excess ion hydration free energy at an electric field E (ion hydration free energy at the field E subtracted by the ion hydration free energy at zero field) of hydrated calcium, sodium, and chlori e ions have been determined by Monte Carlo simulations. A spherical cell containing either one ion and molecular water or only molecular water subjected to an external electri
Free neutral potassium clusters of two different mean sizes were produced using a gas aggregation source. The K 3p core level was probed by means of synchrotron radiation based photoelectron spectroscopy. The absolute binding energy and the intensity ratio of the surface and bulk spectral features were used to obtain independent estimates of the cluster size. Plasmon satellites in core level spect
The proposed MAX IV facility at MAX-lab, Lund University is presented. The project consists of two storage rings at 1.5 and 3 GeV respectively, a 3 GeV linac injector, a facility for short pulses and a Free Electron Laser. The storage rings will cover a broad spectral range and are designed to reach the diffraction limit in a large wavelength range. A new innovative magnet concept and lattice form
This thesis is devoted to fundamental aspects, and to spectroscopic applications of radiative properties in free atoms and ions, as well as in ions doped into crystals. Using the time-resolved laser-induced fluorescence technique, measurements of radiative lifetimes for rare earth elements have been performed in neutral Pr, Nd, Tm, and in singly ionized Sm, Er, Nd, Tm, Yb, as well as in doubly io
Free gases in scattering media and different techniques for such studies are discussed in the present paper. Connections between two techniques that constitute a major research area at our laboratory are presented. One of the techniques concerns measurements of free gas in scattering media, such as human tissue and food products, on a small scale, while the other one is a technique for trace-gas m
This paper explores the effects of roadway and roadside environment characteristics on the speed chosen by drivers. This work is an observational study of 272 segments of two lane roads in Connecticut. Data was collected for lane width, shoulder width, road width, presence of curbs and edge delineation types. For the roadside environment the following variables were also measured: presence of side
The thesis is focused on two major subjects: - Calculation of free energy is of great help in the study of any molecular system. The free energy determines phase behaviour of colloids and polymer solutions. It also controls the conformational properties of single macromolecules, e.g. DNA, proteins, copolymers. One of the most robust computer simulation techniques for free energy estimation is an
The main purpose of this Thesis is the experimental characterization of the electronic and geometric structures of objects called clusters. A cluster consists of a finite group of bound atoms or molecules. Due to its finite size, it may present completely different properties than those of the isolated atom and the bulk. The clusters studied in this work are constituted by rare-gas atoms, organic
We present and discuss the complete set of infrared-active phonon modes in monoclinic-symmetry crystal modification gallium oxide (gallia, β-Ga2O3). The phonon mode set is obtained from a comprehensive analysis of generalized spectroscopic ellipsometry data in the farinfrared and infrared spectral regions investigating various n-type electrically conductive single crystal samples with different fr
BACKGROUND: There was a decrease 1982-2001 in smoking during early pregnancy in Swedish women. We sought to determine whether there was a parallel decrease in socio-economic inequality in smoking. METHODS: Registry data indicating educational level and smoking status at first antenatal visit in all 2,022,469 pregnancies in Sweden 1982-2001 was analysed. Prevalence differences, odds ratios based on
