Persistance et adaptation de Listeria monocytogenes dans le sol : rôle du système de communication Agr

2014

Listeria monocytogenes is a ubiquitous bacterium responsible for listeriosis, a food-borne disease. This pathog•en has been isolated from varions environments of which the telluric environment. The presence of L. monocytogenes in soi! can increase health hazards due to the risk of transfer to vegetables, animais and animal products and water. Considering the role of soil in the circulation of pathogens from fann environment to plant and animal products and eventually to foodstuff, it is critical to identify intrinsic and extrinsic factors that drive the fate of L. monocytogenes in soi!. Genome-wide and transcriptomic analyses found that an important part of the genome of L. monocytogenes (7…

Northern Drosophila montana flies show variation both within and between cline populations in the critical day length evoking reproductive diapause

2013

Reproductive diapause, and its correct timing, plays an important role in the life cycle of many insect species living in a seasonally varying environment at high latitudes. In the present paper we have documented variation in the critical day length (CDL) for adult reproductive diapause and the steepness of photoperiodic response curves (PPRCs) in seven clinal populations of Drosophila montana in Finland between the latitudes 61 and 67°N, paying special attention to variation in these traits within and between cline populations. The isofemale lines representing these populations showed a sharp transition from 0% to 100% in females' diapause incidence in the shortening day lengths, indicate…

Città-porto a prova di futuro. Linee guida per l’integrazione di soluzioni basate sulla natura per l’adattamento climatico e la tutela della biodiver…

2023

Quale è il ruolo della pianificazione nel rispondere alle sfide della crisi climatica e della perdita di biodiversità nei contesti urbano-portuali? Il lavoro di ricerca costituisce un avanzamento del dibattito sulla riqualificazione delle aree portuali, contesti storicamente avulsi dalla considerazione di tematiche legate alla preservazione e valorizzazione degli habitat naturali e degli ecosistemi. La tesi desidera mettere al centro della discussione le città porto mediterranee come ecosistemi e come insediamenti urbani multi-specie, come attrici del cambiamento responsabile di fronte alle crisi e non soltanto nodi infrastrutturali strategici per l’economia, la finanza e gli usi militari. …

Foreign language anxiety : the case of young learners of English in Swedish primary classrooms

2019

Although foreign language anxiety is a widely studied construct assumed to develop from negative experiences of language instruction, few researchers have focused on young learners in this regard. This multiple case study investigates levels and triggers of language anxiety in Swedish primary classrooms under rather favorable learning conditions with a supportive, non-competitive atmosphere, and without formal knowledge requirements or grades. A total of 225 learners, aged 8–12, studying English as their first foreign language completed a self-report questionnaire, a modified version of the Foreign Language Classroom Anxiety Scale (Horwitz, Horwitz, & Cope, 1986), eliciting learners’ reacti…

Prismatic adaptation modulates oscillatory EEG correlates of motor preparation but not visual attention in healthy participants

2018

Prismatic adaption (PA) has been proposed as a tool to induce neural plasticity and is used to help neglect rehabilitation. It leads to a recalibration of visuo-motor coordination during pointing as well as to after-effects on a number of sensorimotor and attention tasks, but whether these effects originate at a motor or attentional level remains a matter of debate. Our aim was to further characterise PA after-effects by using an approach that allows distinguishing between effects on attentional and motor processes. We recorded electroencephalography (EEG) in healthy human participants (9 females and 7 males) while performing a new double step, anticipatory attention/motor preparation parad…

Probabilistic Evaluation of the Adaptation Time for Structures under Seismic Loads

2016

Abstract In this paper, a probabilistic approach for the evaluation of the adaptation time for elastic perfectly plastic frames is proposed. The considered load history acting on the structure is defined as a suitable combination of quasi-statical loads and seismic actions. The proposed approach utilizes the Monte Carlo method in order to generate a suitable large number of seismic acceleration histories and for each one the related load combination is defined. Furthermore, for each load combination the related adaptation time is determined, if any, as the optimal one for which the structure is able to shakedown under the unamplified applied actions. A known generalized Ceradini's theorem i…

Intercultural Profiles and Adaptation Among Immigrant and Autochthonous Adolescents

2015

Few studies examine relationships between intercultural strategies and adaptation among adolescents using a person-oriented approach. Framed from an intercultural psychology perspective, this study used such an approach in order to examine the influence of intercultural profiles, patterns of relationships among variables related to intercultural strategies, on the adaptation of adolescents of both non-dominant and dominant groups. Two hundred and fifty-six adolescents living in Italy and aged from 14 to 18 participated to the study: 127 immigrants from Tunisia (males = 49.61%) and 129 autochthonous (males = 44.19%). Data were collected through self-report questionnaires. Using cluster analy…

Zarządzanie projektami logistycznymi jako fundament w procesie zwiększania zdolności adaptacyjnych przedsiębiorstw na przykładzie realizacji przewozu…

2015

Narastająca niepewność powoduje konieczność wypracowania nowych wzorców i metod zarządzania, aby sprostać odmiennym jakościowo, coraz szybciej zmieniającym się wyzwaniom rynkowym. Realizacja projektów, w tym projektów logistycznych, stała się istotnym elementem działań zarówno każdego przedsiębiorstwa, jak i łańcuchów dostaw. Ranga podejmowanych przedsięwzięć o innowacyjnym oraz niepowtarzalnym charakterze, generowanie nowych rozwiązań i pomysłów realizowanych w formie projektów, są doskonałym odzwierciedleniem adaptacyjności przedsiębiorstw w kierunku przeobrażeń zachodzących w otoczeniu. Ze względu na niepowtarzalność tych przedsięwzięć logistyk może mieć za każdym razem problem z radzeni…

Genome degeneration and adaptation in a nascent stage of symbiosis

2014

Symbiotic associations between animals and microbes are ubiquitous in nature, with an estimated 15% of all insect species harboring intracellular bacterial symbionts. Most bacterial symbionts share many genomic features including small genomes, nucleotide composition bias, high coding density, and a paucity of mobile DNA, consistent with long-term host association. In this study, we focus on the early stages of genome degeneration in a recently derived insect-bacterial mutualistic intracellular association. We present the complete genome sequence and annotation of Sitophilus oryzae primary endosymbiont (SOPE). We also present the finished genome sequence and annotation of strain HS, a close…
