Determination of the isotopic abundances of heavy O3 as observed in arctic ground-based FTIR-spectra

Ground-based FTIR-measurements have been performed at the NDSC (Network for Detection of Stratospheric Change) station on Spitsbergen ((79)degrees N, 12 degrees E). We have investigated several well isolated absorption lines of isotopically heavy O-3 in the 10 mu m region that allowed us to quantify their natural abundances in the arctic atmosphere for the period April 1994 to August 1995, On the

Solubilisation and colonisation of wood ash by ectomycorrhizal fungi isolated from a wood ash fertilised spruce forest

In Sweden application of granulated wood ash has been suggested as a method to supplement nutrient loss resulting from harvesting of forest residues for bioenergy production. Mycelia of two ectomycorrhizal fungi Piloderma sp.I and Ha-96-3. were commonly found to colonise ash granules in a wood ash fertilised spruce forest. Thirty-eight fungal isolates were selected from 10 taxa to investigate the

Explaining Research Utilization: Beyond 'Functions'

With material from a Swedish study of the utilization of social research in city welfare agencies, the authors advocate a sociological analysis of the utilization contexts where use of research takes place. The bases of compliance in the organization and the position of the agencies in regard to conflicts in social welfare politics are shown to have great importance for the way organizations use a

Image analysis and laser induced fluorescence combined to determine biological growth on silicone rubber insulators

High-voltage outdoor insulators made from silicone rubber are sometimes reported to be colonised by microorganisms. When the hydrophobic polymeric surface is covered by a hydrophilic biofilm, the electrical properties of the insulator are altered. In this work, mixed biofilms, similar to those formed on the surfaces of polymeric insulators in the field, were successfully grown on five types of sil

Protection against cold air and exercise-induced bronchoconstriction while on regular treatment with Oxis

This study aimed to compare the duration of protection against exercise-induced bronchoconstriction (EIB) after inhalation of formoterol (Oxis) Turbuhaler with that of terbutaline Turbuhaler and placebo Turbuhaler in asthmatic patients treated regularly with formoterol Turbuhaler 9 microg b.i.d. and inhaled steroids. The study. performed at three centres (Goteborg and Lund, Sweden, and Trondheim,

Regional differences in bladder enlargement and in vitro contractility after outlet obstruction in the rabbit

Purpose: Bladder outlet obstruction leads to bladder enlargement and subsequent decreases in contractile function in vivo and in vitro. We determined whether there were regional differences in bladder wall properties and in vitro contractile responses after 2 weeks of bladder outlet obstruction. Materials and Methods: Male rabbits underwent cystometry. The bladder was then filled to 40 ml. and the

The spectrum of adult congenital heart disease in Europe: morbidity and mortality in a 5 year follow-up period - The Euro Heart Survey on adult congenital heart disease

Aims To describe clinical and demographic characteristics at baseline of a European cohort of adults with congenital heart disease (CHD) and to assess mortality and morbidity in a 5 year follow-up period. Methods and results Data collected as part of the Euro Heart Survey on adult CHD was analysed. This entailed information transcribed from the files of 4110 patients diagnosed with one of eight co

Method for identifying ligands activating either excitatory or inhibitory G-protein-coupled receptors by functional coexpression in Xenopus oocytes

Xenopus oocytes devoid of their follicular enclosure provide a frequently used expression system for investigating receptors that transduce through activation of adenylyl cyclase following injection of the appropriate mRNA. However, due to a low basal activity of the cyclase they cannot be utilized to investigate receptor-mediated reductions in endogenous cAMP levels. In order to overcome this lim

Acne vulgaris - A disease of western civilization

Background: In westernized societies, acne vulgaris is a nearly universal skin disease afflicting 79% to 95% of the adolescent population. In men and women older than 25 years, 40% to 54% have some degree of facial acne, and clinical facial acne persists into middle age in 12% of women and 3% of men. Epidemiological evidence suggests that acne incidence rates are considerably lower in nonwesterniz
