Strain gradient plasticity, strengthening effects and plastic limit analysis
2010
Abstract Within the framework of isotropic strain gradient plasticity, a rate-independent constitutive model exhibiting size dependent hardening is formulated and discussed with particular concern to its strengthening behavior. The latter is modelled as a (fictitious) isotropic hardening featured by a potential which is a positively degree-one homogeneous function of the effective plastic strain and its gradient. This potential leads to a strengthening law in which the strengthening stress, i.e. the increase of the plastically undeformed material initial yield stress, is related to the effective plastic strain through a second order PDE and related higher order boundary conditions. The plas…
Trigger and aperture of the surface detector array of the Pierre Auger Observatory
2010
The surface detector array of the Pierre Auger Observatory consists of 1600 water-Cherenkov detectors, for the study of extensive airshowers (EAS) generated by ultra-high-energy cosmic rays. We describe the trigger hierarchy, from the identification of candidates howers at the level of a single detector, amongst a large background (mainly random single cosmic ray muons), up to the selection of real events and the rejection of random coincidences. Such trigger makes the surface detector array fully efficient for the detection of EAS with energy above 3 x 1018 eV, for all zenith angles between 03 and 603, independently of the position of the impact point and of the mass of the primary particl…
On achieving near-optimal “Anti-Bayesian” Order Statistics-Based classification fora asymmetric exponential distributions
2013
Published version of a Chapter in the book: Computer Analysis of Images and Patterns. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-40261-6_44 This paper considers the use of Order Statistics (OS) in the theory of Pattern Recognition (PR). The pioneering work on using OS for classification was presented in [1] for the Uniform distribution, where it was shown that optimal PR can be achieved in a counter-intuitive manner, diametrically opposed to the Bayesian paradigm, i.e., by comparing the testing sample to a few samples distant from the mean - which is distinct from the optimal Bayesian paradigm. In [2], we showed that the results could be extended for a few sym…
Human inducible nitric oxide synthase (iNOS) expression depends on chromosome region maintenance 1 (CRM1)- and eukaryotic translation initiation fact…
2012
Human inducible nitric oxide synthase (iNOS) is regulated on the expressional level mostly by post-transcriptional mechanisms modulating the mRNA stability. Another important step in the control of eukaryotic gene expression is the nucleocytoplasmic mRNA transport. Most cellular mRNAs are exported via the TAP/Nxt complex of proteins. However, some mRNAs are transported by a different mechanism involving the nuclear export receptor CRM1. Treatment of DLD-1 cells with the CRM1 inhibitor leptomycin B (LMB) or anti-CRM1 siRNAs reduced cytokine-induced iNOS expression. We could demonstrate that the iNOS mRNA is exported from the nucleus in a CRM1-dependent manner. Since CRM1 itself does not poss…
Association of AUUUA-binding Protein with A + U-rich mRNA during nucleo-cytoplasmic transport
1992
Resealed nuclear envelope (NE) vesicles from rat liver containing entrapped exogenous RNA were used to study the effect of adenosine+uridine binding factor (AUBF), present in cytosolic cell extracts, on ATP-dependent transport of A+U-rich RNA (AU+RNA) and A+U-free RNA (AU-RNA) across the NE. This factor specifically binds to A+U-rich sequences present in the 3' untranslated regions of lymphokine and cytokine mRNAs, containing overlapping AUUUA boxes (granulocyte-macrophage colony stimulating factor, interleukin-3). Addition of AUBF to the extravesicular compartment markedly increased the efflux of the in vitro transcribed, capped and polyadenylated AU+ RNAs. Export of entrapped AU- control …
Urban environment and cognitive and motor function in children from four European birth cohorts
2021
[EN]Background: The urban environment may influence neurodevelopment from conception onwards, but there is no evaluation of the impact of multiple groups of exposures simultaneously. We investigated the association between early-life urban environment and cognitive and motor function in children. Methods: We used data from 5403 mother-child pairs from four population-based birth-cohorts (UK, France, Spain, and Greece). We estimated thirteen urban home exposures during pregnancy and childhood, including: built environment, natural spaces, and air pollution. Verbal, non-verbal, gross motor, and fine motor functions were assessed using validated tests at five years old. We ran adjusted multi-e…
Latvijas un Ķīnas ekonomisko attiecību stiprināšana: empīrisks pētījums par Latvijas zīmola potenciālu Ķīnā
2018
Šī darba ietvaros analizēta Ķīnas tirgus izpratne par Latviju un Latvijas zīmoliem, kā arī, tiek novērtēts Latvijas produktu, tūrisma un izglītības eksporta tirgus potenciāls Ķīnas tirgū. Maģistra darba sākumā analizēta zinātniskā literatūra, lai izpētītu attiecības starptautiskās tirdzniecības veicināšanai, tūrisma eksportam, izglītības eksportam un valsts ekonomiskai izaugsmei, un turpinājumā veikta rūpīga Latvijas-Ķīnas divpusējo ekonomisko attiecību izpēte un analīze. Veicot iepriekšminētās darbības, secināts, ka, preču un pakalpojumu eksportu uzlabošana no Latvijas uz Ķīnu var nākt par labu Latvijas ekonomikai. Nākamā darba daļa ir empīrisks pētījums, kas sastāv no autores veiktās apta…

Le site de Sanofi situé à Mourenx, dans le bassin industriel de Lacq (64), produit un médicament antiépileptique, la Dépakine®, dont le principe actif est le valproate de sodium (VPS). Ce site est une installation classée pour la protection de l’environnement (ICPE) soumise à autorisation au titre de l’article L.511-1 et suivants du Code de l’environnement. Les rejets dans l’environnement d’une telle installation sont encadrés par des limites établies sur la base d’une évaluation quantitative des risques sanitaires (EQRS). En 2017, Sanofi Chimie a réalisé une évaluation de l’impact sur la santé et l’environnement des rejets atmosphériques de valproate, en utilisant des valeurs toxicologique…
One-dimensional nonlinear boundary value problems with variable exponent
2018
In this paper, a class of nonlinear differential boundary value problems with variable exponent is investigated. The existence of at least one non-zero solution is established, without assuming on the nonlinear term any condition either at zero or at infinity. The approach is developed within the framework of the Orlicz-Sobolev spaces with variable exponent and it is based on a local minimum theorem for differentiable functions.
Part C notification (reference C/NL/13/01) from Suntory Holdings Limited for the import, distribution and retailing of carnation SHD-27531-4 cut flow…
2015
Requestor: European CommissionQuestion number: EFSA-Q-2015-00126; The Scientific Panel on Genetically Modified Organisms of the European Food Safety Authority (EFSA GMO Panel) has evaluated the overall safety of genetically modified (GM) carnation SHD-27531-4 cut flowers to be imported into the European Union (EU) for ornamental use. The genetic modification results in the flowers having purple petals. The stability of the new colour trait was observed over multiple vegetative generations. The purple colour of the petals comes from the altered expression levels of anthocyanins, common pigments found in edible fruits and vegetables. Considering the intended use of the GM carnation and the po…
