The aim of this study was to investigate the validity of self-patch testing for nickel allergy, in order to determine a cost-effective method for surveillance of the prevalence of nickel allergy. Population-based study including patch testing is the most reliable method to study the prevalence of allergy, but it is expensive and has logistical problems. A total of 191 dermatology patients referred

Prophylaxis and treatment with antiretroviral drugs and the use of elective caesarean section have resulted in a very low mother-to-child transmission of human immunodeficiency virus (HIV) during recent years. The availability of new antiretroviral drugs, updated general treatment guidelines and increasing knowledge of the importance of drug resistance, have necessitated regular revisions of the "

The colloidal gas-liquid phase behaviour has been studied for aqueous mixtures of well-defined spherical particles with short-ranged repulsions mixed with relatively monodisperse poly(ethylene oxide) polymers. We show that our set of experimental phase diagrams are in quantitative agreement with theoretical predictions using generalized free volume theory [G. J. Fleer and R. Tuinier, Phys. Rev. E,

A common approach for the computational modeling of enzyme reactions is to study a rather small model of the active site (20-200 atoms) with quantum mechanical (QM) methods, modeling the rest of the surroundings by a featureless continuum with a dielectric constant of approximately 4. In this paper, we discuss how the residues included in the QM model should be selected and how many residues need

Background : Exposure to mass media provides increased awareness and knowledge, as well as changes in attitudes, social norms and behaviors that may lead to positive public health outcomes. Birth preparedness (i.e. the preparations for childbirth made by pregnant women, their families, and communities) increases the use of skilled birth attendants (SBAs) and hence reduces maternal morbidity and mo

Forskarutbildningen har ett dubbelt syfte, att utbilda framtidens universitetslärare och forskare samt att utgöra rekryteringsbas för andra delar av offentlig sektor och privat sektor. Resultaten av denna alumnundersökning visar att Lunds universitet väl svarar upp mot detta dubbla rekryteringssyfte. Av doktoranderna i undersökningen, riktad till examinerade år 2004, hade nästan nästan samtliga (9

Purpose – The aim is to understand customers' willingness, or unwillingness, to pay a price premium in the market for consumer packaged food and what kind of images brands can use in order to achieve a price premium. Design/methodology/approach – The study is based on a quantitative survey of brand images found in food and branding literature and their impact on loyalty as well as customers' will

The general research question of the present study was to assess the impact of visually salient online adverts on children's task-oriented internet use. In order to answer this question as reliably as possible, an experimental study was constructed in which 9-year-old and 12-year-old Swedish children were asked to solve a number of tasks while interacting with a mockup website. In each trial, web

Controlled vocabularies (CVs), i.e. a collection of predefined terms describing a modeling domain, used for the semantic annotation of data, and ontologies are used in structured data formats and databases to avoid inconsistencies in annotation, to have a unique (and preferably short) accession number and to give researchers and computer algorithms the possibility for more expressive semantic anno

Many birds use a flight mode called undulating or flap-gliding flight, where they alternate between flapping and gliding phases, while only a few bats make use of such a flight mode. Among birds, flap-gliding is commonly used by medium to large species, where it is regarded to have a lower energetic cost than continuously flapping flight. Here, we introduce a novel model for estimating the energet

We studied 1,432 febrile travelers from Sweden who had returned from malaria-endemic areas during March 2005-March 2008. In 383 patients, paired serum samples were blindly analyzed for influenza and 7 other agents. For 21% of 115 patients with fever of unknown origin, serologic analysis showed that influenza was the major cause.

Cancer cells within a given tumor were long regarded as a largely homogeneous group of cells originating from a common progenitor cell. However, it is increasingly appreciated that there is a considerable heterogeneity within tumors also on the tumor cell level. This heterogeneity extends to virtually all measurable properties of cancer cells, ranging from differentiation state, proliferation rate

Contingent self-esteem, where one’s self-value is staked on success and competence, is a particularly vulnerable disposition with impact on well-being. This study compared physiological and behavioral reactivity between individuals self-rated as high and low in competence based self-esteem (N = 61), in a performance situation. To assess reactivity we used a traditional overt measure of blood press

The McStas neutron ray-tracing simulation package is a versatile tool for producing accurate neutron simulations, extensively used for design and optimization of instruments, virtual experiments, data analysis and user training. In McStas, component organization and simulation flow is intrinsically linear: the neutron interacts with the beamline components in a sequential order, one by one. Histor

The shielding at an accelerator-driven spallation neutron facility plays a critical role in the performance of the neutron scattering instruments, the overall safety, and the total cost of the facility. Accurate simulation of shielding components is thus key for the design of upcoming facilities, such as the European Spallation Source (ESS), currently in construction in Lund, Sweden. In this paper

Flow cytometry is a widespread single-cell measurement technology with a multitude of clinical and research applications. Interpretation of flow cytometry data is hard; the instrumentation is delicate and can not render absolute measurements, hence samples can only be interpreted in relation to each other while at the same time comparisons are confounded by inter-sample variation. Despite this, mo

Så vad kan det innebära att skriva om ljud och ljudmiljöer? Hur förvandlas eller tolkas ett medium av ett annat? Skriftställaren, akustikern, musikforskaren, litteraturvetaren, journalisten måste alla brottas med uppgiften att skriva om ljud. Ljudmiljöcentrum samlar i denna volym ett antal skriftställares tankar om ord om ljud.Medverkande: Anders Mildner, Johan Stenström, Annika J Lindskog, Louise
