To simulate post-consumer recycled plastics, selected model contaminants were incorporated into PET bottles using a time saving method. Migration into 3% acetic acid, a cola-type beverage and 95% ethanol was followed during 1 year of storage at 20 and 40degreesC. Aroma compounds previously found in post-consumer PET material were used as model contaminants. Benzaldehyde was found to migrate to the

In this paper, a new frequency offset correction approach for OFDM is proposed to track a wider range of offsets than conventional proposals, without devoting specific pilot symbols for synchronization. This can be attained since, in coherent OFDM, channel estimation is usually performed employing pilot-symbol assisted-modulation (PSAM), based on inserting known symbols in the time-frequency grid.

Objective: To evaluate the performance characteristics of direct and capture ELISA for the detection of PR3-ANCA in Wegener's granulomatosis (WG) in international ANCA reference laboratories. Methods: Serum samples were derived from patients with histological and clinical diagnosis of WG (n = 60), rheumatoid arthritis (RA) (n = 30) and healthy controls (n = 30). Each of them was tested for the pre

The big Malmö newpapers Sydsvenska Dagbladet and Kvällsposten, both owned by the family Wahlgren, involved themselves heavily in Swedish party politics in the 1960s. The Social Democrats had in 1962 been in almost permanent power in Sweden since 1932. There was a desperate wish for change in power among many Swedishy voters. In this atmosphere Olof Wahlgren, Sydsvenska Dagbladet´s deputy editor,

Five experiments examined explicit and implicit memory for information that is congruent with the physical attractiveness stereotype (i.e. attractive-positive and unattractive-negative) and information that is incongruent with the physical attractiveness stereotype (i.e. attractive-negative and unattractive-positive). Measures of explicit recognition-sensitivity and implicit discriminability revea

We investigated several aspects of the role of physical activity in colon and rectal cancer etiology that remain unclear in the European Prospective Investigation into Nutrition and Cancer. This cohort of 413,044 men and women had 1,094 cases of colon and 599 cases of rectal cancer diagnosed during an average of 6.4 years of follow-up. We analyzed baseline data on occupational, household, and recr

Antimicrobial peptides (AMP) are effector molecules of the innate immune system. A cross-functionality exists between AMPs and heparin-binding peptides. Here, we show that the peptides QPTRRPRPGTGPGRRPRPRPR-P (QPT22), derived from proline arginine-rich end leucine-rich repeat protein (PRELP) and KRFKQDGGWSHWSPWSS (KRF17) from thrombospondin exert antimicrobial activities against the Gram-negative

Aims Many patients with sinus node disease or atrioventricular block have previously received pacemakers with only ventricular stimulation (VVI or VVIR). This study aimed to investigate whether quality of life and cardiac function were affected by an upgrade to dual chamber pacing (DDDR or DDIR) following long-term ventricular stimulation. Methods After implantation of an atrial lead and a DDDR pu

This paper presents a unified approach to multiscale detection of transient evoked otoacoustic emissions (TEOAEs). Using statistical detection theory, it is shown that the optimal detector involves a time windowing operation where the window can be estimated from ensemble correlation information. The detector performs adaptive splitting of the signal into different frequency bands using either wav

Korttidspsykoterapi med sex kvinnor och sex män i samband med graviditets- och post partumperioden analyserades med narrativ ansats och med anknytningsteori och affektteori som grund. Syftet med studien var att skaffa kunskap om psykiska besvär hos blivande och nyblivna föräldrar och att undersöka om korttidspsykoterapi med kvinnor och män i samband med barnafödandet i förebyggande syfte kunde avl

The propagation of short cracks in the neighbourhood of grain boundaries have been investigated using a technique were the crack is modelled by distributed dislocation dipoles and the plastic deformation is represented by discrete dislocations. Discrete dislocations are emitted from the crack tip as the crack grows. Dislocations can also nucleate at the grain boundaries. The influence on crack gro

Out-of-plane nuclear motion stimulated in the core-excited state and symmetry breaking due to this nuclear motion have been investigated for B Is excitation in the BF3 molecule by a combination of three different experimental methods: angle-resolved ion-yield spectroscopy, vibrationally resolved resonant Auger electron spectroscopy and quadruple-ion coincidence momentum-imaging technique.

Among psychiatric illnesses, genetically determined disorders usually have an early onset and a severe and complicated course. Gene-environmental interaction is of importance for aggressive impulsive behaviour. For example, alcoholism type II has a high family loading, a severe course, and is often associated with antisocial behaviour. In order to gain further understanding of aggressive and impul

Background: In a sample of patients in clinical occupational medicine we have demonstrated that an upper limb neurological examination can reliably identify patterns of findings suggesting upper limb focal neuropathies. This further study aimed at approaching the diagnostic accuracy of the examination. Methods: 82 limbs were semi-quantitatively assessed by two blinded examiners ( strength in 14 in
