1. When stimulating the local nerves in the bovine ovarian follicle wall preparation (4 Hz, 1 ms pulse duration and 7.5 V between the electrodes) vasoactive intestinal polypeptide reduced the neurogenic contraction and at the highest concentration tested (3 x 10(-7) M) almost abolished the response. Peptide histidine isoleucine only slightly reduced the contraction. 2. Strips from the follicle wal

Seven different strains of mice (wild, C57BL, DBA, B6CBA, A/sn, NZB and NMRI) were continuously exposed to 150 ppm trichloroethylene (TCE) during 30 days. After exposure all strains showed large increases in liver weight, while changes in kidney and spleen weights were small. Plasma butyrylcholinesterase (BuChE) activity increased in males of all strains and in females of strains A/sn and NZB. The

In this article we take the classic meaning of exemplum as a point of departure to show how examples are marked and used in oral discourse on 'others'. The empirical material is a transcribed focus group interview with Swedish students talking about a trip to Warsaw. Examples may be marked in explicit ways but also in implicit ways. Some examples seem recognizable by their allusive nature, others

När vi som företagsekonomer ser på kommuners utveckling med de begrepp och modeller vi är vana att arbeta med, sticker kommunerna ut på många sätt. Kommunerna är ofta de mest resursrika organisationerna i sitt lokala sammanhang. Utifrån traditionella beskrivningar som antal anställda, omsättning, kundbasens omfattning, variation och bredd i serviceutbud, är det få omkringliggande organisationer so

Vegetation patterns of subalpine gully-head mires were investigated in the flat-topped Lammerlaw and Lammermoor Ranges, South Island, New Zealand. Two intensively studied mires each consist of a series of peaty terraces and scarps. Terraces may contain pools, elongated downslope in the narrow, lower altitude mire, but across slope in the broader, upper mire. A crest occurs on some terrace lips, an

OBJECTIVE: To identify risk factors for fever in labor. METHODS: A retrospective case-control study was conducted. Maternal sublingual temperature was measured every 2-4 hours during labor in 3109 of 3860 consecutive term parturients presenting from September 1992 through December 1993. Women who had fever (at least one recorded temperature of 38C or more, n = 72) during labor were compared with t

Twenty-nine rats were subjected to a severe standardized hepatic injury and divided into four groups. In addition to controls, the animals were treated with PASG inflated to 40 mm Hg, PASG and infusion of Ringer's acetate, or PASG and infusion of Ringer's acetate and Dextran 70 in combination. The aim of the infusion therapy was to stabilize the mean aortic blood pressure at 60 mm Hg. PASG signifi

We design a fully polynomial-time approximation scheme for the problem of finding a triangulation of a simple poly-on with a constant number of sources of dilation that achieves the minimum vertex dilation. (c) 2005 Elsevier B.V. All rights reserved.

OBJECTIVE: To investigate the risk of asthma in hairdressers. METHODS: The incidence of asthma was retrospectively estimated in a Swedish nationwide study including all female hairdressers certified from vocational schools from 1970 to 1995, and a stratified sample of women from the general population were referents. A postal questionnaire included questions on respiratory tract symptoms, atopy, s

The accuracy in determination of organ activity of Tc-99m was investigated, with activity estimated from gamma camera images of phantoms, using the, conjugate view method. The accuracy depends on several parameters such as the choice of background correction method, the accuracy in determination of the effective attenuation coefficient and the thickness of the body and organs and on the determinat

Given a 2-dimensional conformal foliation F of a Riemannian manifold M, the problem of finding a 1-dimensional subfoliation G, conformal in M, whose leaves have prescribed geodesic curvature in the leaves of 9 is equivalent to a Pfaff differential system on a circle bundle over M. We study such pairs of foliations on a 3- and 4-manifold.

Sweden is the only Scandinavian country that uses closed treatment institutions based on coercive measures within the child welfare system, on a large scale, for the education and treatment of young criminal offenders and drug users. In Sweden there are in 2002 some 30 “homes for specialized supervision” of varying sizes and degrees of specialization – all run by a national board of institutional
