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

We focus on two problems with the evolutionary scenario proposed: (1) It bypasses the question of the origins of the communicative and semiotic features that make language distinct from, say, pleasant but meaningless sounds. (2) It does little to explain the absence of language in, for example, chimpanzees: Most of the selection pressures invoked apply just as strongly to chimps. We suggest how th

Popular Abstract in Swedish Conflicts and Contracts är en studie av generationslänken i dagens Singapore med fokus på landets kinesiska befolkning. Det huvudsakliga syftet är att undersöka hur den snabba moderniseringen av samhället har påverkat förehållandet mellan äldre och yngre. På mindre än tre decennier har Singapore etablerat sig som en ekonomiskt framgångsrik stadsstat med en högutbildad bThe main purpose of this thesis is to examine the impact of social change on Chinese intergenerational relations in contemporary Singapore. Within only three decades, Singapore has turned into a wealthy and sophisticated metropolis with a highly educated labor force. The massive transformation, however, has been accompanied by the emergence of a deep and complex generation gap. Apart from the leap

This paper describes a model for mobile radio channels that includes consideration of directions of arrival and is thus suitable for simulations of the performance of wireless systems that use smart antennas. The model is specified for 13 different types of environments, covering macro- micro- and picocells. In this paper, a hierarchy of modeling concepts is described, as well as implementation as

A high fibre and a low fibre breakfast meal were given to eight non insulin dependent diabetics ( NIDD ), and eight controls. Blood glucose response was monitored continuously for three hours and characterized using a straight line model. After the high fibre meal the rates of increase and decrease in blood glucose concentration were slower both in diabetics and controls than after the low fibre m

I denna rapport beskrivs ett stort antal laboratorieförsök beträffande deformationer hos husbyggnadsbetong. För krypstudierna tillverkades 8 st betongtyper varav hälften med hög lufthalt och hälften med självkompakterande egenskaper. Parallellt utfördes studier av hållfasthet, krympning och inre relativa fuktigheten. Fältförsök utfördes på bjälklag i ett bostadshus i Malmö.
