Two methods for visual evaluation of image quality of clinical radiographs have been compared. In visual grading analysis (VGA) specified anatomical structures in an image are visually compared with the same structures in a reference image, and in a free-response forced error (FFE) experiment - an extension of conventional ROC (receiver operating characteristics) analysis - the objective is to cor
During spring and autumn 2001, we screened 13,260 migrating birds at Ottenby Bird Observatory, Sweden, and found 3.4% were infested with ticks. Four birds, each a different passerine species, carried tickborne encephalitis virus(TBEV)-infected ticks (Ixodes ricinus). Migrating birds may play a role in the geographic dispersal of TBEV-infected ticks.
This e-book contains contributions from two sessions at the archaeological conference Nordic TAG VIII that took place in Lund in 2005. It is also the first volume of a digital publication, Archaeology @ Lund, published by the Department of Archaeology and Ancient History at Lund University. The two sessions that are published together here are The Practical Aspects of the History of Archaeology an
Popular Abstract in Swedish The last period of life among older people has been very little explored, even though it is well known that for the majority of the population death will occur in old age, both in Sweden and in other western countries. The intention in Swedish society is to provide high quality end of-life care for everyone (SOU 2001:6), not just to those receiving care in a hospital orThe aim of this thesis was to investigate old people's care and quality of life during the last period of life, but also to investigate their own and next-of-kin's experience of this phase. The thesis is based on four studies using separate samples. The sample (n=1198) in study I was drawn from the care and services part of the sub-study ?Good Aging in Skåne? (GAS). The criteria for inclusion in s
Popular Abstract in Swedish Stommen i "det sydkoreanska miraklet" utgjordes av chaebolkonglomeraten, som inom ramen för "developmental state" blev instrumentet för ekonomisk tillväxt. Med ett minimum av eget kapital men med privat ägarkontroll och genom lånefinansiering expanderade dessa företag. Hur kunde denna "omöjliga" konfiguration överleva? Avhandlingen analyserar hur detta kunde fortgå ändaThe chaebol conglomerates, which constituted the backbone of the "South Korean miracle", became the instrument for economic growth within a framework laid down by the "developmental state". With a minimum of own capital, but with private owner-control and loan-financing, these chaebols were able to expand. How could this "impossible" configuration survive? The thesis analyses how this could contin
Wind noise was measured in four behind-the-ear hearing instruments with different microphone openings. A silent airflow of 7 m/s was directed toward the ear of a Kemar head and the resulting wind noise was measured. The amplification was set to an insertion gain of 35 dB at 1.6 kHz. The wind noise amplitude at the position of the drum ranged from 84 to 97 dB(A). The hearing instrument with a parti
In semen. the gel proteins SgI and SgII (semenogelins I and II) are digested by PSA (prostate-specific antigen), resulting in liquefaction and release of motile spermatozoa. Semen contains a high concentration of Zn2+, which is known to inhibit the protease activity of PSA. We characterized the binding of Zn2+ to SgI and SgII and found evidence that these proteins are involved in regulating the ac
Background Mast cells are known to accumulate at sites of inflammation and upon activation to release their granule content, e.g. histamine, cytokines and proteases. The secretory leukocyte protease inhibitor (SLPI) is produced in the respiratory mucous and plays a role in regulating the activity of the proteases. Result We have used the HMC-1 cell line as a model for human mast cells to invest
Cobalt silicide has emerged as a leading contact material in silicon technology due to its low resistivity, high stability and small lattice mismatch. In this study, 0.2-0.4 mu m thick Co films were deposited on Si(100) wafers by RF magnetron sputtering at room temperature, and annealed at temperatures from 600 to 900 degrees C in vacuum. As-deposited and annealed samples were characterized by Rut
High resolution core-level spectroscopy was utilized to study the clean and NH3 exposed Si(100)2×1 surface. The clean surface exhibits two approximately equal intensity surface core-level components at −0.48 and 0.28 eV binding energy referred to the bulk component. NH3 exposure at 300 K induces two surface core-level components at 0.31 and 0.72 eV relative binding energy that can be assigned to s
Investigations of chemical bonding and electronic structure features for polycrystalline Ni(II) phthalocyanine (NiPc), Ni(II) tetrabenzoporphyrin (NiTBP), Ni(II) 2,3,7,8,12,13,17,18-octaethylporphyrin (NiOEP), Ni(II) 5,10,15,20-tetraisobutylporphyrin (NiTiBuP), Ni(II) 5,15-diphenylporphyrin (NidPP) and Ni(II) 5,15-diisobutylporphyrin (NidiBuP) have been performed by means of high-resolution soft X
Three hundred and forty-eight children from Skaraborg County, Sweden, admitted to hospital with abdominal injuries over a 30-year period (1951-1980), have been analysed and compared with all patients with abdominal injury (1407) admitted to hospital from the same area during the same period. The number of children admitted in the second half of the period was greater than during the first but the
