The effects of sulfate anions on the uptake of Pb(II) onto goethite were investigated at the molecular level using in situ Pb L-III-EXAFS and ATR-FTIR spectroscopies. Macroscopic uptake data show that Pb uptake can be enhanced by at least 30% at pH 5 in the presence of 3.16 mM sulfate and that sulfate uptake at pH 7 can be enhanced by more than a factor of 3 in the presence of 1.0 mM Pb. Consisten
Av: Josefin 2017-01-16 Min reseberättelse från Vilnius, Litauen. När man fick chansen att söka en utbytestermin i ett annat land ville jag absolut ta chansen. Det var en hel del förberedelser inför sökandet och allt började med att man var tvungen att hitta skolor som hade de utbud som matchade de kurser som jag skulle läsa på hemmaplan, inom Logistics Service Management. Det var även en del förbe

A complete set of all optical phonon modes predicted by symmetry for bixbyite structure indium oxide is reported here from a combination of far-infrared and infrared spectroscopic ellipsometry, as well as first principles calculations. Dielectric function spectra measured on high quality, marginally electrically conductive melt grown single bulk crystals are obtained on a wavelength-by-wavelength
More than 20 years ago, an oxytocin/vasopressin-like peptide, CLITNCPRGamide, was isolated from the locust, Locusta migratoria [Proux JP, et al. (1987) Identification of an arginine vasopressin-like diuretic hormone from Locusta migratoria. Biochem Biophys Res Commun 149:180-186]. However, no similar peptide could be identified in other insects, nor could its prohormone be cloned, or its physiolog
Unsatisfactory indoor air quality (IAQ) may be due to the spread of chemical or biological compounds from building into the indoor air. One way to avoid the problem is to attach an emissions barrier indoors onto the surfaces from which the emissions are being spread (floor, walls, ceiling). Here we report on the use of the surface emissions trap (cTrap), an emissions barrier developed at Lund Univ
Molecular radiotherapy combines the advantages of systemic administration of highly specific antibodies or peptides and the localized potency of ionizing radiation. A potential target for molecular radiotherapy is the cell surface antigen CD44v6, which is overexpressed in numerous cancers, with limited expression in normal tissues. The aim of the present study was to generate and characterize a pa
I denna uppsats behandlas den svenska regleringen av barnpornografibrottet och vad den omfattar efter 2010 års lagändring. Syftet med uppsatsen är att belysa om syftet med lagändringen har uppnåtts, att göra all befattning olagligt för att mer effektivt kunna bekämpa barnpornografi. Uppsatsen ger en detaljerad redogörelse för de ändringar som gjorts sedan regleringen infördes 1980. Utöver det tas In this essay the Swedish regulation regarding child pornography is discussed focused on parts included in the regulation after the amendment 2010. The purpose is to discuss if the intention with the new amendment has been achieved, that is to criminalize all types of behaviors related to child pornography for enabling more effective crime prevention. The essay presents a thorough review on what c
Due to the recent advances in digital detector technology, there is an increasing trend in the use of digital mammography (DM) as a concurrent modality with screen-film mammography (SFM). In order to fully realize its potential, the components of a DM system should be optimized with respect to clinical image quality in order for clinicians to make accurate diagnoses. The studies in this work invol
Background: Previous studies have demonstrated that low-grade red blood cell transfusions (RBC) given to septic patients are harmful. The objectives of the present study were to compare mortality and morbidity in non-septic critically ill patients who were given low-grade RBC transfusions at haemoglobin level > 70 g L–1 with patients without RBC-transfusions any of the first 5 days in intensive ca
BackgroundFetal cardiac magnetic resonance imaging (MRI) improves the diagnosis of congenital heart defects, but is sensitive to fetal motion due to long image acquisition time. This may be overcome with faster image acquisition with low resolution, followed by image enhancement to provide clinically useful images.PurposeTo combine phase-encoding undersampling with super-resolution neural networks
Objectives: The use of rituximab (RTX) in multiple sclerosis (MS) is a rapidly increasing choice of disease-modifying therapy. Efficacy outside specialized university hospital-based care is not yet systematically investigated. Our aim was to evaluate off-label RTX treatment for MS at a general hospital in Sweden. Materials and Methods: Subjects with definite MS with at least one rituximab infusio
Background: Prospectively and systematically collected real-world data on vedolizumab are scarce. We aimed to assess the long-term clinical effectiveness of vedolizumab in inflammatory bowel disease (IBD). Methods: This study was a prospective, observational, multicentre study. Overall, 286 patients with active IBD were included (Crohn’s disease, n = 169; ulcerative colitis, n = 117). The primary
The present work performs unsteady Reynolds-averaged Navier-Stokes simulations to study the effect of turbulence-chemistry interaction (TCI) on diesel spray flames. Three nozzle diameters (d0) of 100, 180, and 363 μm are considered in the present study. The Eulerian stochastic fields (ESF) method (with the TCI effect) and well-stirred reactor (WSR) model (without the TCI effect) are considered in
Major volcanic eruptions are one of the most devastating and unpredictable events for all societies past and present. Althoughmajor progress has been made by archaeologists in understanding volcanic impacts on past societies, almost all this work hasfocused on urban or settled agricultural societies. In contrast, there is a major gap in knowledge about how forager communitieswere able to respond a
Background: Adjuvant chemotherapy is standard treatment for other solid tumours, but to date has not proven effective in prostate cancer. Objective: o evaluate whether six cycles of docetaxel alone improve biochemical disease-free survival after radical prostatectomy for high-risk prostate cancer. Design, setting, and participants: Open-label, randomised multinational phase 3 trial. Enrolment of 4
I denna studie utfördes en TEM (transient elektromagnetisk) undersökning på den Bolivianska altiplanon, norr om staden Oruro. I Oruro finns det ett underskott av dricksvatten och deras huvudsakliga vattenförsörjning kommer från aquiferen Challapampa. Målet med undersökningen var att kartlägga djup till bottnen på aqviferen, topografin av botten samt, om möjligt, akvitarder innom akviferen. De omkrIn this study a TEM (transient electromagnetic) investigation where preformed on the Bolivian altiplano north of the city Oruro. There is a deficit of drinking water in Oruro and the aquifer Challapampa is their main source of water. With this investigation the objective was to map the bottom limitation of the Challapampa aquifer and, if possible, restraining structures within the aquifer, aquitar
En arbetsmiljö är både fysisk och psykosocial. Den fysiska delen är enkel att överblicka eftersom den är objektiv, medan den psykosociala är lite mer komplicerad då den är subjektiv och personer uppfattar den olika. I uppsatsen utreds begreppet psykosocial arbetsmiljö för att ge en förståelse för dess innebörd och relevans till ämnet. Kränkande särbehandling är det begrepp som används i svensk rätA work environment is both physical and psychosocial. The physical part is easy to overlook because it is objective, while the psychosocial is a bit more complicated since it is subjective and people perceive the differently. In the essay the concept of psychosocial work environment is examined in order to provide an understanding of its meaning and relevance to the subject. Victimization is the c
I ett flertal utredningar utförda av den franska brottsbekämpande myndighet framkom det snabbt att en viss telefon hittats med personer som tillhör den organiserade brottsligheten. Denna telefon visade sig vara en EncroChat telefon som innehar en stark kryptering. Detta ledde till att de franska myndigheterna startade en operation i syfte att dekryptera EncroChat. Operationen ägde rum i Frankrike In several investigations carried out by the French law enforcement authorities, it quickly emerged that a certain phone was found with people belonging to organized crime. This phone turned out to be an EncroChat phone that has strong encryption. This led to the French authorities launching an operation to decrypt EncroChat. The operation took place in France but affected people in other countrie
