A model commonly used to describe the separation of biomolecules was used to simulate the harsh environment when eluting neodymium, samarium, europium and gadolinium with a hot acid. After calibration, the model was used to optimise the preparative separation of europium, as this is the most valuable of the four elements. A kinetic dispersive model with a Langmuir mobile phase modulator isotherm w

Using the ATLAS detector, a centrality-dependent suppression has been observed in the yield of J/psi mesons produced in the collisions of lead ions at the Large Hadron Collider. In a sample of minimum-bias lead-lead collisions at a nucleon-nucleon centre of mass energy root s(NN) = 2.76 TeV, corresponding to an integrated luminosity of about 6.7 mu b(-1), J/psi mesons are reconstructed via their d

Although the stored energy of an antenna is instrumental in the evaluation of antenna Q and the associated physical bounds, it is difficult to strictly define stored energy. Classically, the stored energy is either determined from the input impedance of the antenna or the electromagnetic fields around the antenna. The new energy expressions proposed by Vandenbosch express the stored energy in the

Introduction: The Lund University Faculty of Engineering's LibQual+® survey 2007 showed that students and faculty had difficulties finding the information they needed at the libraries' Websites. To be able to improve the Websites, we needed to find out how the users navigated the Websites, as well as what content they needed. Method: Twenty-four students and faculty members were filmed and audio-t

En genväg för att snabbare nå den hägrande matsäcken resulterade i en ny vildväxande art för Sverige. Torbjörn Tyler var den hungrige.

Background: Valid and reliable ischemic stroke subtype determination is crucial for well-powered multicenter studies. The Causative Classification of Stroke System (CCS, available at http://ccs.mgh.harvard.edu) is a computerized, evidence-based algorithm that provides both causative and phenotypic stroke subtypes in a rule-based manner. We determined whether CCS demonstrates high interrater reliab

Background: Knowledge regarding the health-related quality of life (HRQoL) of children with celiac disease remains limited and inconclusive. We investigated the HRQoL of three groups of 12-year-olds with: i) undetected celiac disease ii) clinically diagnosed celiac disease, and iii) without celiac disease. Methods: A school-based cross-sectional multicenter screening study invited 18 325 children,

This thesis presents an improved version of the classic relay autotuner. The proposed autotuner uses an asymmetric relay function to better excite the process in the experiment phase. The improved excitation provides the possibility to obtain better models and hence better tuning, without making the autotuner more complicated or time consuming.Some processes demand more accurate modeling and tunin

ALICE has unique capabilities among the LHC experiments for particle identification (PID) at mid-rapidity (vertical bar eta vertical bar < 0.9) over a wide range of transverse momentum (pT). In this proceeding(1) recent measurements of PT spectra for pi, K, K-s(0), p, and Lambda in p-Pb collisions are presented and compared to results from Pb-Pb and pp. In particular the implications for the quest

Mixtures of methanol and acetate as carbon source were investigated in order to determine their capacity to enhance denitrification and for analysis of the microbial composition and carbon degradation activity in activated sludge from wastewater treatment plants. Laboratory batch reactors at 20 degrees C were used for nitrate uptake rate (NUR) measurements in order to investigate the anoxic activi

Statligt stöd till kommuner i finansiella svårigheter förknippas ofta med efterföljande brister i kommunernas ekonomiska hushållning, eftersom kommunerna förväntar sig att staten griper in i svåra tider. Tidigare studier har dock undersökt stöd utan tydligt specificerade krav på motprestationer från mottagarnas sida. Vi studerar utvecklingen av kostnader och resultat under 2000-talet i de kommuner

We examine how Private Investment in Public Equity (PIPE) contracts allocate contingent cash flow rights between investors and issuers and the role of placement agents in PIPE contract design. Issuers advised by expert agents agree to more investor-friendly terms than issuers advised by nonexpert agents. Expert agents appear to help issuers understand the payoff consequences of negotiable terms. M

Background: One of the main causes of mortality and morbidity following subarachnoid haemorrhage (SAH) is the development of cerebral vasospasm, a frequent complication arising in the weeks after the initial bleeding. Despite extensive research, to date no effective treatment of vasospasm exists. Prostacyclin is a potent vasodilator and inhibitor of platelet aggregation. In vitro models have shown

Computational and experimental methods have been used to investigate the flow field, power and mixing time in a fully baffled stirred vessel with two six-blade Rushton turbines. Flow in a stirred tank involves interactions between flow around rotating impeller blades and stationary baffles. In computational fluid dynamics (CFD), the flow field was developed using the sliding mesh (SM) approach. Th

This paper pursues the idea that uninterpretable features are not present in syntax, but are instead a product of the interfaces. In particular, it argues that formal feature values belong to PF only, i.e., that they are not syntactic objects but PF ‘translations’ of more abstract syntactic structures and correlations. It follows that case is nonexistent in syntax and it also follows that agreemen

The effect of ozone additive on the enhancement of the burning velocity for premixed methane-air flames is investigated by both experimental measurements and kinetic simulations. Laminar burning velocities with and without O(3) were directly measured using the Heat Flux method. The O(3) molecules were introduced into the system by a dielectric-barrier-discharge ozone generator installed in the O(2

Bakgrunden till projektet var det tidigare projektet Motorfordonsförares väjningsbeteende gentemot cyklande. Syftet med detta projekt var att studera om och i så fall hur motorfordonsförares väjningsbeteende kan kopplas till trafiksäkerhetssituationen på en plats. Ett annat syfte var att genom enkäter få en bild av hur trafikanter uppfattar väjningsreglerna vid cykelöverfarter. Sju platser från de
