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.
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
Projekt Trapphuset Rosengård, Malmö, inleddes i maj 2008 och avslutades i april 2010. Projektet är en efterföljare till projekt Trappan, som pågick under perioden februari 2006 till juni 2007. Båda projekten har byggt på samarbete med AUC/AIC Rosengård och ABF/ABL Malmö, samt finansierats av medel från Europeiska Socialfonden och medfinansierats av Malmö Stad. Den här utvärderingsrapporten avser d
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
The acid base speciation of surface-active carboxylate ions in the surface region of aqueous solutions was studied with synchrotron-radiation-based photoelectron spectroscopy. The protonated form was found at an extraordinarily large fraction compared to that expected from the bulk pH. When adding salts containing the weak acid NH4+ to the solution, the fraction of the acidic form at the surface i
It is hypothesized that nonverbal behaviors of team sport athletes have an important impact on the course of the game. However, quantitative research on this topic is rare, partly due to a lack of scientifically sound coding schemes developed to assess nonverbal behavior in team sports. The aim of the present study is to develop a coding scheme that measures nonverbal behaviors displayed by female
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,
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
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
Structured illumination (SI), which is an imaging technique that is employed in a variety of fields, permits unique possibilities to suppress unwanted signal contributions that carry misguiding information such as out-of-focus light or multiply scattered light. So far SI has been applied mostly for averaged imaging or for imaging of slowly occurring events because it requires three acquisitions (s
Background: Prostate cancer metastasizes to regional lymph nodes and distant sites but the roles of lymphatic and hematogenous pathways in metastasis are not fully understood. Methods: We studied the roles of VEGF-C and VEGFR3 in prostate cancer metastasis by blocking VEGFR3 using intravenous adenovirus-delivered VEGFR3-Ig fusion protein (VEGFR3-Ig) and by ectopic expression of VEGF-C in PC-3 pros
For ionic surfactants in general, a change from simple to polymeric counterions leads to increasing attraction between micelles, condensing them in a concentrated phase. In the present study, two novel “complex salts” were prepared in which the cationic surfactant hexadecyltrimethylammonium was neutralized by two different copolyions, both having poly(methacrylate) main chains randomly decorated w
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
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
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
