This article is based on the belief that research focused on PR tourism is of fundamental importance to understanding the role of PR in contemporary culture. Our analysis shows that tourism has not received much attention from PR researchers and that a critical perspective uncovers a host of key issues in promotional culture: power, politics and diplomacy in international communication; risk, ethi
In this article the authors suggest that chaos theory can provide us witha new perspective on archaeology. Newtonian thinking is predominantin archaeology, as well as in the humanities in general. This results inthe hegemony of analytic methods and a linear way of thinking on causeand effect. However, chaos theory has shown that behind many phen-omena that may seem random lies order. Since these c
Podoscyphic acid 1, a fungal metabolite inhibiting RNA-directed DNA polymerises, was synthesised in four steps starting from dodecanal. The concluding ester hydrolysis of 4 was not feasible with chemical reagents, only enzymatic hydrolysis was mild enough to release the highly reactive natural product in good yields.

Background: Thalidomide has a chiral centre, and the racemate of (R)- and (S)-thalidomide was introduced as a sedative drug in the late 1950s. In 1961, it was withdrawn due to teratogenicity and neuropathy. There is now a growing clinical interest in thalidomide due to its unique anti-inflammatory and immunomodulatory effects. Objective: To critically review pharmacokinetic studies and briefly rev
Protein tyrosine phosphatase (PTP)-1B, encoded by the PTPN1 gene, inactivates the insulin signal transduction cascade by dephosphorylating phosphotyrosine residues in insulin signaling molecules. Due to its chromosomal location under a chromosome 20 linkage peak and the metabolic effects of its absence in knockout mice, it is a candidate gene for type 2 diabetes. Recent studies have associated com
With shrinking technologies and higher clock rates comes the possibility to transform multi chip implementations to a single System on Chip (SoC). Implementing clock distribution and limiting the power consumption becomes increasingly troublesome with increased clock rate and chip area. Therefore, designing large Systems on Chip makes it necessary to search for new implementation methods. In this
A series of celloendoglucanases: Bacillus agaradhaerens Cel 5a, Humicola insolens Cel 5a, H. insolens Cel 7b, H. insolens Cel 45a, Trichoderma reesei Cel 7b, and T reesei Cel 45a were used to hydrolyse carboxymethylcellulose (CMC) and the hydrolysis products were investigated with a novel liquid chromatography-mass spectrometry (LC-MS) method. Separation was achieved using a graphitised carbon chr
Treatment of [(mu-H)Os-3(CO)(10)(mu-OMe)] (1) with dppm {dppm = bis(diphenylphosphino)methane} at 110 degrees C gave the known compound [Os-3(CO)(10)(mu(2)-eta(2)-dppm)] (2) and the new compound [(mu-H)Os-3(CO)(8)(mu-OMe)(mu(2)-eta(2)-dppm)] (3). A similar reaction of 1 with dppe {dppe=bis(diphenylphosphino)ethane} afforded two products, [(mu-H)Os-3(CO)(8)(mu-OMe)(mu(1)-eta(2)-dppe)] (5) and [(mu-
We have investigated laser-induced fluorescence frompost mortem human arteries in order to find spectroscopic properties allowing discrimination between normal and atherosclerotic vessel wall. A pulsed nitrogen laser emitting light at a wavelength of 337.1 nm was used as an excitation source. The fluorescence spectrum from 370 to 700 nm was captured and analysed by an optical multichannel analyser
This study examines processes of transnational alliance-building among political parties in the European Union (EU). It is associated with theories of transnational relations, neofunctionalist integration theory and domestic politics approaches to international co-operation and integration. The overall aim of the study is to contribute to the understanding and growth of knowledge of transnational
Popular Abstract in Swedish Under 1920-talet och framåt accelererade moderningseringsprocessen på många plan och det svenska samhället kom att allt mer förändras. Följande studie handlar i mycket om hur man på olika sätt kan förhålla sig till den nya tid som kommer. Gertud Lilja var verksam mellan 1924 och 1964. Under 1920-40-talen var hon en känd och diskuterad författare, men med tiden har henneThe aim of this thesis is to present and discuss the author Gertrud Lilja with a special focus on her relationship to modernity from a feminist perspective. In the 1920s Lilja was regarded as an interesting and promising author. Ten years later she was seen as a conservative and popular author who wrote mainly for women. As this is the first published thesis that discusses Gertrud Lilja it focuses
In a retrospective analysis of 450 patients with rheumatoid arthritis the cervical films were reviewed to detect vertical dislocation of the C1 and C2 vertebrae. A frequency of 10 per cent was found among all patients and of 24 per cent among those with cervical arthritis. The authors' method of measuring vertical dislocation at conventional radiography turned out to be superior to the method of M
