Traveller and fan identities of the Finnish football fans
2010
This research deals with the Finnish football fans and their motives to travel and follow sports. The reason for studying this area is to increase information and knowledge about the consumer behaviour of sport fans. Special attention is paid to the question of why fans behave the way they do. What factors affect fans’ decision making processes when they travel? Does sport have an influence on the travelling process? Are there any similarities between the reasons of travelling and attending sport events? In this study sport fans are divided into different fan types according to their motives to attend sport events as spectators and in different traveller typologies according their motives t…
Liquid Phase Micro-Extraction of Linear Alkylbenzene Sulfonate Anionic Surfactants in Aqueous Samples
2011
Hollow fiber liquid phase micro-extraction (LPME) of linear alkylbenzene sulfonates (LAS) from aqueous samples was studied. Ion pair extraction of C10, C11, C12 and C13 homologues was facilitated with trihexylamine as ion-pairing agent, using di-n-hexylether as solvent for the supported liquid membrane (SLM). Effects of extraction time, acceptor buffer concentration, stirring speed, sample volume, NaCl and humic acids were studied. At 10–50 µg L−1 linear R2-coefficients were 0.99 for C10 and C11 and 0.96 for C12. RSD was typically ~15%. Three observations were especially made. Firstly, LPME for these analytes was unusually slow with maximum enrichment observed after 15–24 h (depending on sa…
Dynamics of supercooled confined water measured by deep inelastic neutron scattering
2017
In this paper, we present the results of deep inelastic neutron scattering (DINS) measurements on supercooled water confined within the pores (average pore diameter ~ 20 Ã ) of a disordered hydrophilic silica matrix obtained through hydrolysis and polycondensation of the alkoxide precursor Tetra-Methyl-Ortho-Silicate via the sol-gel method. Experiments were performed at two temperatures (250 K and 210 K, i.e., before and after the putative liquidâliquid transition of supercooled confined water) on a âwetâ sample with hydration h ~ 40% w/w, which is high enough to have water-filled pores but low enough to avoid water crystallization. A virtually âdryâ sample at h ~ 7% was also inve…
Cartographie de la pollution lumineuse zénithale en Bourgogne à partir de données de population et d'occupation du sol
2007
L'étude a pour but de fournir une première cartographie très simple de la pollution lumineuse sous SIG afin de faciliter l'interprétation géographique et, par la suite, la mise en relation avec d'autres facteurs. Bien sûr, un passage vers un modèle prédictif devient nécessaire si l'outil se destine à être une aide décisionnelle ou un outil de recherche ayant pour but d'analyser les conséquences des changements de certains de ses paramètres. Ainsi, un tel modèle pourra servir à évaluer et analyser les conséquences de la pollution lumineuse générée par la construction d'un nouveau quartier résidentiel, d'une zone indus‐ trielle, de nouvelles infrastructures routières.
Gordonia sp. SoCg alkB gene confers the ability to degrade and use n-alkanes as carbon source in Gram positive bacteria
2010
Gordonia sp. SoCg, a Gram positive strain able to grow on long chain n-alkanes1, possess a single copy of alkB2 gene, whose product is required for n-alkane hydroxylation3. An analysis of alkB flanking regions revealed five ORFs which were designed as orf1, rubA3, rubA4, rubB and alkU, according to the sequence 14 homology with that of known alk clusters3. In G. sp. SoCg the transcription of these genes was induced by long-chain and solid n-alkanes as revealed by quantitative RT-PCR, and the essential role of alkB in nalkane degradation was demonstrated by the construction of an alkB disruption mutant strain3. The SoCg alkB gene was successfully expressed in Streptomyces coelicolor M145 (M1…
Associations between muscle strength, spirometric pulmonary function and mobility in healthy older adults
2014
Background: Pathological obstruction in lungs leads to severe decreases in muscle strength and mobility in patients suffering from chronic obstructive pulmonary disease. The purpose of this study was to investigate the interdependency between muscle strength, spirometric pulmonary functions and mobility outcomes in healthy older men and women, where skeletal muscle and pulmonary function decline without interference of overt disease. Methods: 135 69 to 81‐yr‐old participants were recruited into the cross‐sectional study, which was performed as a part of European study MyoAge. Full, partial and no mediation models were constructed to assess the interdependency between muscle strength (handgr…
