Popular Abstract in Swedish Strävan efter förnyelse präglar det moderna samhället och dess organisationer. Överlevnad och framgång anses vara förknippad med förmågan att förändra och ompröva befintliga förhållanden. Det gäller snart sagt alla typer av verksamheter. Vi vet samtidigt att organisationer inte enbart utmärks av sin förmåga att ständigt förnyas. Etablerade arbetssätt, organiseringsformeThe aim of this thesis is to generate a theory of renewal in organizations. In modern society, characterized by the idea of progress, renewal has become an axiomatic assumption behind organizational existence. From an institutional perspective, the continuous search for new organizational forms and practises can be described as a process of imitation. The thesis acknowledges renewal as a process o

0 Context.-Plasma anti-Xa and anti-IIa activities correlate with the dose of low-molecular-weight heparin, and D-dimer and thrombin-antithrombin complexes are markers of procoagulant activity. Objective.-To investigate the relationship between plasma coagulation parameters and patient characteristics, including renal function, thromboprophylaxis, and incidence of venous thromboembolism (VTE) in th

Information on the effects of thyroid hormone on smooth muscle contractile protein expression and mechanical properties is sparse. We have addressed the following questions. (1) Can thyroxine hormone alter myosin isoform composition in smooth muscle? (2) Can a change in myosin isoform composition lead to altered mechanical properties in smooth muscle? (3) Are alterations, if occurring, equal in fa

The effect of random laser phase fluctuations on stimulated photon echoes (SPEs) and on coherently added SPEs was studied and evaluated both experimentally and analytically with statistical methods. The general concept of describing laser frequency fluctuations as a stationary stochastic process is presented and applied to three specific SPE configurations. The effect of phase fluctuations on eras

Absorption and fluorescence spectra of 2-R-5-phenyl-1,3,4-oxadiazoles (R = H, methyl, tert-butyl, trifluoromethyl, amino, phenyl, benzyl) were studied experimentally and by time dependent density functional theory (TDDFT) methods. In acidic media a substantial red shift is observed due to the presence of conjugate acid forms. Two conjugate acid forms (3H and 4H) are possible for unsymmetrically su

Abstract in German Die CEAP-Klassifizierung für chronische Venenleiden wurde 1994 durch ein internationales Ad-hoc-Komitee des American Venous Forum entwickelt, durch die Society for Vascular Surgery unterstützt und 1995 in die „Reporting Standards in Venous Disease“ inkorporiert. Inzwischen benutzen die meisten publizierten klinischen Arbeiten das CEAPSystem, ganz oder in Teilen. Um die KlassifizThe CEAP classification for chronic venous disorders (CVD) was developed in 1994 by an international ad hoc committee of the American Venous Forum, endorsed by the Society for Vascular Surgery, and incorporated into "Reporting Standards in Venous Disease" in 1995. Today most published clinical papers use all or portions of CEAP. Rather than have it stand as a static classification system, an ad ho

Fungal laccase (Lc) from the basidiomycete Trametes hirsuta was immobilized on top of a carbon ceramic electrode using physical absorption. Direct, unmediated heterogeneous electron transfer between Lc and the carbon ceramic electrode (CCE) under aerobic conditions was shown. The bioelectrocatalytic reduction of oxygen on Lc-CCE started at about 430 mV vs. Ag vertical bar AgCl vertical bar KClsat

An enantioselective synthesis of (-)-pregaliellalactone (1), a biosynthetic precursor of the potent fungal metabolite ( -)-galiellalactone (3) produced by several ascomycetes, is reported. When fed to a culture of Galiella rufa, 1 was efficiently converted to 3. (C) 2002 Elsevier Science Ltd. All rights reserved.

Human cancers are characterized by chromosomal aberrations, and an increasing number of specific balanced rearrangements have been found among malignant hematologic disorders. Most solid tumors, however, exhibit a much more complex cytogenetic pattern. Although these chromosome changes show a nonrandom distribution, tumor-specific aberrations are uncommon, and the solid tumors often contain a larg

Endothelin-1 (ET-1), a 21 amino acid peptide exerts a wide range of biological activities including vasoconstriction, mitogenesis and inotropic effects on the heart. In this study, we examined whether endocardial endothelial cells express ET-1 and evaluated its functional properties. Using immunofluorescence localization method, we demonstrated cytoplasmic staining of ET-1 in the human endocardial

For combustors a heat transfer augmentation of two to five times higher than expected has been reported. Experiments, where the temperature profile in the tail pipe of the pulse combustor has been measured, give no indication why the heat transfer should be augmented. The objective is to study the heat transfer of an oscillating flow between two parallel plates. A set of governing equations is for

OBJECTIVES: To investigate the significance of ACE gene insertion/deletion (I/D) polymorphism in the frequency of autoimmune manifestations in sarcoidosis. DESIGN: In patients with sarcoidosis the ACE gene I/D polymorphism was detected with PCR on genomic DNA. The patients with sarcoidosis were divided according to the presence (n = 30) or absence (n = 32) of autoimmune manifestations. The former
