Popular Abstract in Swedish Denna doktorsavhandling i Rättssociologi handlar om barns rättigheter och barnarbete i Paraguay. Problematiken kring barnarbete i Paraguay är central för avhandlingen och författaren har undersökt samt beskrivit de rättsliga ideal som är tänkta att upprätthålla och stärka det rättsliga skyddet för barns rättigheter. De rättsliga idealen kontrasteras sedemera mot den norThe present study is composed of eight chapters relating to children's rights and child labor activity in the Republic of Paraguay. The problem of child labor in Paraguay is central for this study and the legal ideals that are intended to uphold and strengthen the rights of the child are described and contrasted with the present normative reality in which the children work and live. The discrepanc

Caloplaca erecta Arup & H. Mayrhofer is described here as new to science. It belongs to a group of dwarf-fruticose species, but cannot be accommodated within any of the known species of that group. It forms dense cushions of erect lobes on siliceous rocks, and is known only from Mt. Maungatua. This is the second dwarf-fruticose species of Caloplaca in the Australasian area, in addition to C. c

The paper describes the approach used at the Department of Automatic Control at Lund Institute of Technology to maintain a high level of practical laboratory experiments. The Department integrates laboratory experiments into its control courses. If the laboratory exercises are properly organized and the student volume is sufficiently large, it is possible to combine a high level of practical labor

A first clinical evaluation has been made of the performance of a newly devised immunofluorometric assay for measuring plasma concentrations of activated protein C (APC) in complex with protein C inhibitor (PCI). The method was compared with testing for other markers of hypercoagulability in a case-control study comprising 123 patients with clinical suspicion of deep vein thrombosis (DVT). The dia

As a component of herbicides, the fate of glyphosate (PMG) in the environment is of significant interest. The nature of PMG adsorption on mineral surfaces plays a significant role in the degradation of PMG. The adsorption of PMG on goethite (alpha-FeOOH) has been studied as a function of pH and PMG concentration. Adsorption was investigated with batch experiments, attenuated total reflectance Four

BACKGROUND: Hepatitis C virus (HCV) is a known blood-borne hepatotropic virus for which antibody screening of blood donors is universally practiced. The newly identified GB virus C (GBV-C) and its strain variant hepatitis G virus (HGV) are of unknown pathogenic significance, and screening of blood donors for this agent has not yet been implemented. Polymerase chain reaction (PCR) is the most sensi

The immobilization of meldola blue (MB) on silica gel coated with niobium oxide (SN) and electrochemical investigation of its behavior as well as the electrocatalytical oxidation of nicotinamide adenine dinucleotide in reduced form (NADH) by this modified electrode are described. The modified silica containing 1.4 mmol g(-1) of niobium oxide dispersed on its surface adsorbed 55 mumol g(-1) of MB.

Stability of systems in the presence of bounded uncertain time-varying delays in the feedback loop is studied. The delay parameter is assumed to be an unknown time-varying function for which the upper bounds on the magnitude and the variation are given. The stability problem is treated in the integral quadratic constraint (IQC) framework. Criteria for verifying robust stability are formulated as f

Structural and electronic properties of a small anatase TiO2 nanocrystal sensitized by the ruthenium dye N3 (Ru(4,4‘-dicarboxy-2,2‘-bipyridine)2(NCS)2) have been investigated using density functional theory (DFT) with support from Hartree−Fock (HF) and time dependent DFT (TD-DFT) calculations. Significant structural adjustments of both the dye and the nanocrystal are predicted to be induced by the

Background and Objectives: Intense pulsed light (IPL) systems are increasingly used for treatment of photo damaged skin. In the present study, we investigated the clinical efficacy and safety of two different wavelength bands generated by the same IPL device. Study Design/Materials and Methods: An IPL device was equipped with either a 555-950 nm filter (VL), or a 530-750 nm filter (PR). Results: F

The study is based on monitoring data on the seasonal variation during four (1996-1999) vegetation periods, as well as long-term summer data on submerged vegetation, nutrients, light, phyto-plankton and zooplankton in Lake Krankesjon, a shallow, calcium-rich, moderately eutrophic take in southern Sweden. The lake has been in the clear water state with abundant submerged vegetation since the end of

In this report we study how a time-varying system with a time-periodic integral kernel (impulse response), g(t,\tau)=g(t+T,\tau+T), can be expanded into a sum of essentially time-invariant systems. This allows us to define a linear frequency response operator for periodic systems, called the Harmonic Transfer Function (HTF). The HTF is a direct analog of the transfer function for time-invariant sy

Interleukin (IL)-8 receptor knockout (KO) mice were shown to have a dysfunctional neutrophil response to urinary tract infection and to develop renal scarring. Intravesical Escherichia coli infection stimulated epithelial chemokine secretion and IL-8 receptor expression in control mice. Neutrophils migrated through the tissues and crossed the epithelial barrier into the urinary tract lumen. In mur

Numerical simulations of two-phase fluid flow and heat transfer with or without phase change have been carried out. The Volume-of-Fluid (VOF) model was used in the simulations, and a procedure for considering the phase change process was developed. The Piecewise Linear Interface Calculation (PLIC) method is employed for the interface reconstruction, to keep the sharp interface. The coupling betwee

Sonographic pictures of the brain of 19 newborn infants who died at a mean age of 4.2 days after birth (range 1-23 days) were examined independently by five experienced sonographers. In all infants information on postmortem brain pathology was available. Diagnoses made by the sonographers based on the sonographic pictures were compared with the gross postmortem findings. The results of the study s
