A large number of diluents were screened to determine the optimum combination between diluent and extractant. Combinations of a C8 tertiary amine and aromatic diluents or of a C12 tertiary amine and aliphatic diluents do not lead to third-phase formation. A flow-sheet for a solvent-extraction process for treatment of various qualities of wet-process phosphoric acid solutions is proposed. Based on

The local structure of Cd(II) surface complexes adsorbed onto manganite (gamma-MnOOH) has been investigated by extended X-ray absorption fine structure (EXAFS) spectroscopy. Adsorption experiments were carried out within the pH range 7.4-9.8 and with surface coverage from 2.2 to 8.9 mu mol/m(2). Quantitative analysis of the EXAFS spectra shows little difference in the local coordination environmen

A new work organization was introduced in administrative surveying work in Sweden during 1998. The new work organization implied a transition to a client-centred team-based organization and required a change in competence from specialist to generalist knowledge as well as a transition to a new information technology, implying a greater integration within the company. The aim of this study was to f

Levels of mRNA for c-fos, nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), TrkB, and TrkC were studied using in situ hybridization in the rat brain at different reperfusion times after unilateral middle cerebral artery occlusion (MCAO). Short-term (15 min) MCAO, which does not cause neuronal death, induced elevated BDNF mRNA expression confined to ipsilat

The exposure to isocyanates is more of an occupational problem than a consumer problem. The main route of exposure is assumed to be through inhalation. Isocyanates that have high vapor pressure, such as TDI, can be airborne at room temperature. Other isocyanates such as MDI are volatile only when heated. Industrial processes that can cause exposure to isocyanates are, for example, spraying or heat

OBJECT: Subcutaneously intermittent administration of low molecular weight heparin (LMWH-Fragmin®) - (120IU/kgx2 BW) -in unstable angina has been introduced clinically during the last year, after reports of the FRISC and FRIC studies as an alternative to continous infusion of standard heparin. Fragmin® could possible endanger postoperative haemostasis after CABG due to uncomplete reversal of anti-

Precipitation can be quantified using a rain gauge network, or a remotely sensed precipitation product. Ultimately, the choice of dataset depends on the particular application, the catchment size, climate and the time period of study. In a region with a long record and a dense rain gauge network, the elevation-modified ground-based precipitation product, PRISM, has been found to work well. However

In the present work, oregano leaves (Origanum vulgare L.) are explored as natural source of nutraceuticals with antioxidant activity. To do this, subcritical water extraction (SWE), a new environmentally friendly technique, is employed as extraction procedure and HPLC coupled to DAD is used for the chemical characterization of the extracts. Moreover, the radical scavenging 1,1-diphenyl-2-picrylhyd

In this work new methods based Nuclear Magnetic Resonance (NMR) have been developed to measure different kinds of structural properties in soft materials. The advantage of using NMR as a technique to measure material properties is that it is non-destructive, which makes it possible to measure on the actual piece of material that will be used for the application. One does not have to be concerned

The treatise is concerned with the source-—the “Grund”--of the bindingness of law. I contend, first, that the “presupposition” of the basic norm, on a certain reading of Kelsen’s doctrine, can be understood as constituting a normative source of positive law, and, secondly, that this reading of Kelsen admits of addressing the issue of the (formal) legitimacy of supra-national and “directly applicab

This paper uses a new and detailed survey of cigar making employers and employees to investigate two related discrimination issues. First, were piece rate cigar makers – the skilled aristocracy of this industry – paid differently by gender? We find that they were, but that the differences can be more than explained by differences in characteristics such as age and experience. Second, we ask whethe

The application of geophysics may assist in solving environmental, geotechnical and exploration problems. One commonly used method in such applications is electrical resistivity tomography (ERT). In order to interpret the results, inversion is needed to create models estimating distribution of resistivity in the ground. Several inversion programs are available for geophysicists to use. It is there

Eight patients with colloid cysts of the third ventricle were examined with CT and MR. In six, surgical resection was performed and the material was subjected to histologic evaluation; the concentrations of trace elements were determined by particle-induced X-ray emission. Stereotaxic aspiration was performed in two. The investigation showed that colloid cysts are often iso- or hypodense relative

RTK GNSS is a way of deciding the position of a GNSS receiver with high precision. It should theoretically be possible to determine the position with the precision of a couple of centimeters. Traditionally the RTK GNSS system consists of a base station and a rover. The base station knows its position and compares that to the information it gets from the satellites in order to calculate the error.

Med den ökande portföljen av olika lösningar när man letar efter nya mobilappar och webbverktyg finns det ett behov att utmärka sig. En av de möjliga lösningarna för att fånga och hålla fast användarna är genom att införa gamification som motiverar användaren och ger dem möjlighet att känna sig mer engagerade med ens produkt.

För att uppsatsens ska fylla sitt syfte har en fallstudie gjorts på CRC (Convention on the Rights of the Child) och ACRWC (African Charter on the Rights and Welfare of the Child) och uppsatsens frågeställning lyder; Påverkar de postkoloniala strukturerna den afrikanska barnrätte

Studies have described the phenomenon of voluntary sexual exposure among youth online but only a few focus on the typical young person who has this experience. The purpose of this study was to investigate Swedish youth with experience of voluntary sexual exposure online, with regard to Internet behavior, social background, and psychosocial health including parent-child relationships. A representat

Lightweight wooden-framed constructions have steadily increased their market share in Sweden during the last two decades. Achieving acoustic and vibration comfort in wooden-based buildings is, however, still a challenging task. Wood is high in both strength and stiffness in relation to its weight, but its variability has repercussions on how sound propagates, this triggering sound insulation probl

Preservatives are biologically active substances mainly used in water-based products to prevent the growth of microorganisms. Most people are exposed to them on a daily basis. Formaldehyde is one of the oldest and most commonly used preservatives. However, it is a well-known contact sensitiser in dermatitis patients. The aims of this work were: i) to investigate the prevalence of contact allergy t
