la prospection systématique d’un fond de rivière : l’exemple du Doubs
2020
La présentation des méthodes mises en œuvre et des résultats obtenus à l’occasion d’une opération de prospection subaquatique systématique menée sur la rivière Doubs, en amont de Verdun-sur-le-Doubs (Saône-et-Loire), illustre en grandeur réelle l’intérêt de la démarche adoptée, fondée sur des principes simples, dans la perspective d’un inventaire systématique du patrimoine fluvial immergé. La diversité des vestiges découverts et leur répartition sur la longue durée en soulignent la pertinence mais également, s’il en était encore besoin, la réalité du formidable potentiel archéologique que recèlent les cours d’eau. The presentation of the methods used and results obtained during a systematic…
Autonomous vehicle with communicative driving for pedestrian crossing: Trajectory optimization
2020
Connected and autonomous vehicles (CAV) is a key technology for this century. One of the main challenges is to define a smart interaction behavior of CAV with the other road users. The challenge is mainly raised at conflicting points where path of CAV intersects with the other users. Recent studies show interaction with humans is a big challenge. It not only requires a collision avoidance system but also more communicative behaviors of the CAV. More precisely, pedestrian needs to understand the intention of the incoming CAV whether it will cross first or not according to its speed profile. One way to overcome this issue is to design optimal trajectory control of the CAV that matches with th…

Naujojo žmogaus sukūrimo idėjos užuomazgų galima rasti senovės Graikijoje ir Romoje, taip pat utopistų, švietėjų kūriniuose, teologiniuose tekstuose, tačiau ši ideologema galutinai susiformavo XIX a. pabaigoje, o bandymai ją realizuoti praktiškai sietini su (para)totalitarizmo įsigalėjimu. Vienas iš žinomiausių tokių bandymų pavyzdžių – siekis sukurti Naująjį sovietinį žmogų. Šis bandymas nuo kitų skiriasi komunistine ideologija, kuri kiekvienam reiškiniui suteikia „papildomų reikšmių ar funkcijų“ (Prozorov, 2013, p. 210). Kitaip tariant, visus dalykus SSRS galima suprasti ir paaiškinti tik diktatūros tikslu – utopinė ateities visuomenė „komunizmas“, kurios vardu valstybė viską ir visus reg…
A COLAB model Of workplace transformation in the criminal justice context
2021
AbstractThis chapter presents the COLAB model for promoting organisational learning and innovation with potential application in criminal justice-related organisations. We describe this model as a toolkit that built on the Change Laboratory model of workplace transformation but one augmented with the beneficial components of Activity Clinics, Boundary Crossing Workshops and Codesign methods and developed within the criminal justice context. Limitations and future directions for the model are discussed.
Sister-chromatid exchange in cultured lymphocytes of ewes and their newborn lambs
1984
The incidence of sister-chromatid exchange (SCE) in cultured lymphocytes of ewes and their newborn lambs was determined using the BrdU-Giemsa technique. In all ewe-lamb pairs, the SCE rate in the lambs was less than that of the ewes. The mean SCE frequencies per chromosome of the ewes after lambing and of the newborn lambs were 0.1909 and 0.1581, respectively. The statistical analysis shows that a significant difference exists between SCE in the adult female sheep and their lambs. At the same time, a negative correlation was observed between SCE rate and cell proliferation. The results of this study are compared with those of previous reports on age-dependency of SCE.
Effects of ageing on peroxidase activity and localization in radish (Raphanus sativus L.) seeds.
2010
Peroxidase activity was assayed in crude extracts of integument, cotyledons and embryo axis of radish seeds, deteriorated under accelerated ageing conditions. Over five days of ageing, in which germination decreased from 100 to 52%, the enzyme activity in integument was higher than that in other seed parts, increasing in the first days of ageing and then decreasing sharply in extremely aged seeds. Polyacrylamide gel electrophoresis analysis showed four peroxidase isoenzymes with MM of 98, 52.5, 32.8 and 29.5 kDa in the embryo axis of unaged seeds, and only the 32.8 and 29.5 kDa MM isoforms in the integument and cotyledons. In these parts of the seed, only the 29.5 kDa MM isoenzyme increased…
Tra spazi e funzioni. La crisi dello spazio urbano prima, durante e dopo il Covid-19
2022
Fin dagli albori dell'età urbana, i problemi e i valori dell'insediamento urbano sono variati notevolmente nel corso dei secoli, ma l'importanza della struttura spaziale urbana non è mai stata cancellata. Oggi la città è ancora al centro della nostra civiltà, ma le relazioni tra sistemi socio-ecologici nidificati sono più complesse perché le interazioni uomo-ambiente non sono bidirezionali. L'ascesa dell'Antropocene, una nuova era dirompente ed erosiva causata dall'Umanità, comporta una crisi economica, demografica e ambientale, come dimostrano le attuali pandemie. Il mese scorso le notizie ci hanno detto che il nuovo coronavirus non è stato il primo caso di virus che salta la specie, raggi…
Polychromatic femtosecond fluorescence studies of metal–polypyridine complexes in solution
2011
Femtosecond-resolved broadband fluorescence studies are reported for[ M(bpy)(3)](2+) (M = Fe, Ru), RuN3 and RuN719 complexes in solution. We investigated the pump wavelength dependence of the fluorescence of aqueous [ Fe(bpy)(3)](2+) and the solvent and ligand dependence of the fluorescence of Ru-complexes excited at 400 nm. For all complexes, the (MLCT)-M-1 fluorescence appears at zero time delay with a mirror-like image with respect to the absorption. It decays in <= 30-45 fs due to intersystem crossing to the (MLCT)-M-3 states, but a longer lived component of similar to 190 fs additionally shows up in RuN719 and RuN3. No solvent effects are detected. The very early dynamics are character…

Dynamics of spin state conversion processes in the solid state
1989
High spin (HS) ⇌ low spin (LS) conversions in transition metal complexes are nonradiative transitions between spin states. In this contribution, we present a study of the temperature and pressure dependence of the HS ⇌ LS intersystem crossing dynamics. For some iron(II) spin-crossover complexes, the rate constants were determined by line shape analysis of57Fe Mossbauer spectra. Their temperature dependence is described by an Arrhenius equation, their pressure dependence is interpreted within absolute rate theory. HS → LS conversion rates at low temperatures were determined from the relaxation of light-induced formation of HS states, monitored by optical spectroscopy. Deviations from a simpl…
