Analysis of expression of the gene encoding for the nuclear autoantigen La/SS-B using reporter gene constructs.
1998
In earlier studies mRNA isoforms encoding for the nuclear autoantigen La were identified. In an alternative La mRNA form the exon 1 was replaced with the exon 1'. Moreover, exon 1' La mRNAs were found to start at different 5'-regions. In dependence on the 5'-start the exon 1' La mRNAs encoded for up to three open reading frames upstream of the La frame, which starts in the exon 2. The exon 1' was located in the intron about 70 nts downstream of the exon 1. The exon 1' La mRNA was proposed to be the result of a promoter switch in combination with an alternative splicing mechanism. The commonly used technique to study the expression of a eucaryotic gene is to fuse a reportergene immediately d…
Fractional frequency collective parametric resonances of an ion cloud in a Paul trap
1998
ion cloud ina Paul trap driven at simple fractions of twice the secular frequency of the trap by an additionally appliedquadrupole field. The fractional resonances are observable only if the excitation field surpasses a criticalstrength. Odd-even staggering of the thresholds is observed.@S1050-2947~98!51307-8#PACS number~s!: 32.80.Pj, 07.75.1h
Ranking world tourist destinations with a composite indicator of competitiveness: To weigh or not to weigh?
2019
Abstract This paper contributes a weighted composite indicator of competitiveness for 136 world tourist destinations. To that end, Data Envelopment Analysis and Multi-Criteria-Decision-Making techniques are used with raw indicators from the 2017 edition of the Travel & Tourism Competitiveness Report of the World Economic Forum (WEF). An outstanding feature of our approach is that weights are endogenously generated. Furthermore, the role played by several variables in tourism competitiveness is assessed using truncated regression and bootstrapping. The ranking of world tourist destinations produced by our weighted composite indicator of competitiveness is, however, fairly similar to that der…
Electron trapping centres and cross sections in LiNbO3studied by57Co Mössbauer emission spectroscopy
1999
Fast electron trapping processes and aliovalent charge states following the 57Co(EC)57Fe decay are studied in undoped, 5.4 mol% Mg-doped and 0.1 mol% Fe-doped LiNbO3 in various thermochemical reduction (TCR) states. Static 57Co Mossbauer emission spectra of congruent Mg:LiNbO3 recorded at T = 4.2 K in external magnetic field of 4.6 T are presented. Trapping cross section ratios are derived for Fe3+Li, Nb5+Li and Mg2+Li. A method to determine trap concentrations for TCR states of LiNbO3 is outlined. The electron-capture distance of the traps is found to be 2.7±1.4 nm. As this is much smaller than the 6 keV Auger-electron penetration depth, it is concluded that the distribution of the alioval…
Self-trapping of charge polarized states in four-dot molecular quantum cellular automata: bi-electronic tetrameric mixed-valence species
2014
Abstract Our interest in this article is prompted by the problem of the vibronic self-trapping of charge polarized states in the four-dot molecular quantum cellular automata (mQCA), a paradigm for nanoelectronics, in which binary information is encoded in charge configuration of the mQCA cell. We report the evaluation of the electronic states and the adiabatic potentials of mixed-valence (MV) systems in which two electrons (or holes) are shared among four sites. These systems are exemplified by the two kinds of tetra–ruthenium (2Ru(II)+ 2Ru(III)) clusters (assembled as two coupled Creutz–Taube dimers) for which molecular implementation of mQCA was proposed. The tetra–ruthenium clusters incl…

The dead do not dress: contribution of forensic anthropology experiments to burial practices analysis
2012
International audience; The specific question of clothing presence in burial context is often answered positively, thanks to artifacts like brooches for example. But when artefacts are missing, the task is more difficult, and frequent osteological arguments can only suggest the presence of clothing with the deceased. The gap in determining the presence of clothing is essentially related to a misunderstanding of the effect of clothing on the rate of human decomposition, and thus on the final arrangement of bones (in both forensic and archaeological contexts). Some forensic experiments have been conducted in this regard (essentially in the United States) but no synthesis or archaeological app…
Functionnalized Surface Acoustic Wave Sensors for the Detection of Hazardous Gases
2018
International audience; In this work, we show the capabilities of Surface Acoustic Wave (SAW) devices to probe the properties of gas sensitive materials for the manufacturing of hazardous gas sensors. The great capabilities of cobalt corroles for the trapping of carbon monoxide (CO) were exploited to produce selective sensors. These corroles were deposited on SAW delay lines surfaces and then exposed to carbon monoxide (CO) in standard conditions. Concentrations of a few hundreds of ppb were measured emphasizing the interest of such sensors for the detection of CO. Another type of sensitive layers exhibiting specific porosity adapted to the trapping of formaldehyde (CH$_2$O) were deposited …
Internkontroll og kvalitetssikring av tjenestene i kommunale boliger for mennesker med psykiske lidelser
2015
Masteroppgave velferdsstudier- Universitetet i Agder, 2015 Siden etableringen av Opptrappingsplanen for psykisk helse (1999-2008) har det vært en målsetting å oppnå økt frivillighet i psykisk helsevern, med større fokus på brukermedvirkning og mindre bruk av tvang og makt. Det er i senere tid forsket mye på om man har nådd målsettingene i Opptrappingsplanen. Mye av forskningen har blant annet fokusert på hvordan kommunene har klart å følge opp med antall boliger, hvordan instansene samhandler og om brukermedvirkning overholdes. De seneste årene har det også kommet noen nyere rapporter om kvalitet i tjenestene og bruk av tvang. Dataene fra disse rapportene er hentet fra helseforetakene og si…
