The Swedish National Resource Centre for Physics Education (fysik.org) was created at Lund University by the Swedish Government in 1994. Its 20th anniversary was celebrated 31 March to 1 April at the Island of Hven, which became an EPS historic site in 2013. The theme for the anniversary conference was 'From science education research to education—on research-based development projects.
The treatment of metastatic renal cell carcinoma (mRCC) has been changed by the introduction of targeted agents. Consideration of individual patient factors, such as previous treatment and prognostic risk, e.g. according to the Memorial Sloan-Kettering Cancer Center (MSKCC) risk criteria), can assist in ensuring that patients receive appropriate targeted therapies. Available clinical evidence show
We have performed a serological survey of HPV type 16-antibody prevalence by age and sex in Sweden and used it as a basis for modelling the optimal vaccination strategies in this population. Samples of 3317 subjects were tested for HPV16-specific antibodies. The observed age-specific seroprevalences along with sexual behaviour data were used to infer parameter values for a mathematical model repre
OBJECTIVE: to investigate how women who attended group antenatal care experienced the information they received, compared with women who attended traditional antenatal care, and their satisfaction with the form of care. The aim was also to determine the effect of group antenatal care on women's social networks compared with traditional antenatal care. DESIGN AND SETTING: a pilot study with an inte
Abstract Phagocytosis and killing of microorganisms are complex processes that involve tightly regulated membrane traffic events. Because many signaling molecules associate with membrane rafts and because these structures can be found on azurophilic granules, we decided to investigate raft recruitment and the signaling requirements for azurophilic granule secretion during phagosome maturation. At
Phosphatidylethanol (PEth) represents a group of glycerophospholipid homologues where ethanol by phospholipase D has been bound at the position that normally contains an amino-alcohol. Since the formation of PEth is specifically dependent on ethanol, the diagnostic specificity of PEth as an alcohol biomarker is theoretically 100%. The half-life of PEth in blood is approximately 4 days. The amount
Arterial diameter change is related to distending blood pressure and is used in estimation of arterial stiffness parameters. A common technique to track the arterial walls is by integration of wall velocities estimated by different methods using cross correlation or tissue Doppler. However, because of the high pulse repetition frequency and the need for separate pulsing sequences, the B-mode image
For radionuclide therapy, individual patient pharmacokinetics can be measured in three dimensions by sequential SPECT imaging. Accurate registration of the time series of images is central for voxel-based calculations of the residence time and absorbed dose. In this work, rigid and non-rigid methods are evaluated for registration of 6-7 SPECT/CT images acquired over a week, in anatomical regions f
A multi-stage assembly network is considered. A number of end items should be delivered at a certain time. Otherwise a delay cost is incurred. End items and components that are delivered before they are needed will cause holding costs. All operation times are independent stochastic variables. The objective is to choose starting times for different operations in order to minimize the total expected

This study examined emotional influences on the hypothesized event-related potential (ERP) correlates of familiarity and recollection (Experiment 1) and the states of awareness (Experiment 2) accompanying recognition memory for faces differing in facial affect. Participants made gender judgments to positive, negative, and neutral faces at study and were in the test phase instructed to discriminate
A new method for investigation of axial-beam absorption detection for improved detection limits in microcolumn separations is reported. The method is based on fluorescence imaging of light absorption along a separation capillary. The probing UV light is introduced at one end of the capillary and shows an exponential fall-off along the capillary. As the UV light propagates through the sample peaks,
Fourier Series and the derivative were used in this study for analysing time series of remotely-sensed data. The technique allows fundamental characteristics of time series data to be quantified. In Fourier analysis a function in space or time is broken down into sinusoidal components, or harmonics. The first and second harmonics are a function of the mono or bi-modality of the curve, demonstrated
Background: Prospective follow-up of heroin users is known to be difficult due to their unstable lifestyle, and high follow-up rates have usually demanded major tracking efforts. In Sweden, mobile telephones are commonly used by heavy drug users for drug trading. Objectives: This methodology study aims to examine the efficacy of mobile telephone contact for prospective follow-up interviews with in
The n-CoDeR recombinant antibody gene libraries are built on a single master framework, into which diverse in vivo-formed complementarity determining regions (CDRs) are allowed to recombine. These CDRs are sampled from in vivo-processed and proof-read gene sequences, thus ensuring an optimal level of correctly folded and functional molecules. By the modularized assembly process, up to six CDRs can
BACKGROUND: Several strategies have been used to reach non-attending women in organized cervical-cancer-screening programs, with varying success. Self-sampling (SS) for HPV is effective for increasing coverage in screening programs, but requires expensive commercial sampling kits. OBJECTIVE: We aimed to evaluate if vaginal SS, without commercial preservatives was adequate for HPV testing. ST
Questions concerning the human–nature relationship have received attention both within contemporary Christianity and Buddhism. Since the twentieth century an interesting and fruitful dialogue has been going on between the two religions. This article describes and discusses possible themes for a Buddhist–Christian dialogue on issues of environmental philosophy. The theoretical starting-point is the
Investigators in modern molecular/genetic epidemiology studies commonly analyze data on a vast number of candidate genetic markers. In such situations, rather than conventional estimation of effects (odds ratios), more accurate estimation methods are needed. The author proposes consideration of empirical Bayes and semi-Bayes methods, which yield 'adjustments for multiple estimations' by shrinking
