Effects of Physical and Cognitive Training on Gait Speed and Cognition in Older Adults : A Randomized Controlled Trial
2021
Gait speed is a measure of health and functioning. Physical and cognitive determinants of gait are amenable to interventions, but best practices remain unclear. We investigated the effects of a 12‐month physical and cognitive training (PTCT) on gait speed, dual‐task cost in gait speed, and executive functions (EFs) compared to physical training (PT) (ISRCTN52388040). Community‐dwelling older adults, who did not meet physical activity recommendations, were recruited (n=314). PT included supervised walking/balance (once weekly) and resistance/balance training (once weekly), home exercises (2‐3 times weekly) and moderate aerobic activity 150 minutes/week in bouts of >10 minutes. PTCT included …
Muscle-tendon mechanics and energetics during walking, running and jumping.
2012
In the human lower limb, muscles and tendon tend to interact in an efficient manner during common movements like walking, running and jumping. This pattern of interaction exploits the ability of muscles to produce forces efficiently at low shortening velocities, whilst tendons act as springs that help to store elastic energy during the contact phase, and return a large proportion of the energy in the pushoff phase. This pattern of muscletendon interaction can be disrupted in novel tasks or as a consequence of ageing or disease, resulting in a decrease in movement efficiency. peerReviewed
Izraelskie inspiracje amerykańskiej wojny z terrorem
2016
Celem rozdziału jest wyjaśnienie, w jakiej mierze polityka Izraela wobec jego wrogów inspirowała amerykańskie zmagania w ramach tzw. wojny z terrorem. Autorzy skupiają się na trzech obszarach - torturach, administracyjnych zatrzymaniach i tzw. celowanych zabójstwach. Wszystkie one uznano za legalne w systemach prawnych izraelskim i amerykańskim, podczas gdy są one zakazane przez prawo międzynarodowe, w tym konwencje genewskie. Amerykanie po zamachach z 11 września 2001 roku poszli w ślady państwa żydowskiego w tych kwestiach. Izrael, państwo, które od lat otrzymuje wielkie wsparcie ze Stanów Zjednoczonych, wskazał tym drugim sposoby radzenia sobie z terroryzmem.
From ‘no dogs here!’ to ‘beware of the dog!’ : restricting dog signs as a reflection of social norms
2019
Signs in public space reflect ‘normalcy’ in a community. The authors ask what restricting signs tell us about a society? In order to explore the system and variation in the ways dog signs manifest different norms and control, they compare two different data sets: dog signs in a Northern European town, Jyväskylä in Finland, and two Eastern European villages in Romania. They apply a qualitative methodology based on visual communication, geosemiotics and linguistic landscape studies. The focus of the article is on the resources of addressing and the visual semiotics of the image. The investigated communities seem to create a complementary distribution of what they regulate that is also displa…
Kształcenie akademickie a niepełnosprawność - aktualny problem współczesnej edukacji
2018
Wybór kierunku kształcenia, dokonywany przez młodego człowieka, powinien być determinowany jego indywidualnymi predyspozycjami, możliwościami psychofizycznymi oraz sprecyzowanymi potrzebami i celami życiowymi. Powyższe założenie odnosi się również do osób z niepełnosprawnością. Zgodnie z przyjętą i propagowaną ideą normalizacji, to nie sam człowiek, ale środowisko go otaczające ma zostać przygotowane tak, aby każdy student mógł kształcić się na wybranym przez siebie kierunku. Zatem uczelnie wyższe zaczęły otwierać się dla osób z niepełnosprawnością, a kształcenie na tym poziomie stało się oczekiwanym standardem. Celem artykułu jest ukazanie znaczenia możliwości kształcenia na poziomie wyższ…
Catalytic hydrothermal liquefaction of municipal sludge in subcritical water
2021
In the last decades, the dwindling of the fossil sources of energy coupled with the growth of energy demand and of waste production prompted the research in developing novel industrial technologies for renewable energy production and waste valorization. Hydrothermal liquefaction (HTL) is a good alternative to transform wet biomasses as microalgae, macroalgae, agricultural residues, food waste, and municipal sludge (MS) into value-added products with high efficiency and decreasing the amounts that has to be disposed of. HTL takes place in an aqueous environment, without the energy cost of drying the biomass, at 300-400°C and pressure of 10-40 MPa [1,2]. At these operative conditions, an inte…
Waste heat recovery from a marine waste incinerator using a thermoelectric generator
2012
Published version of an article published in the journal: Journal of Electronic Materials. Also available from the publisher at: http://dx.doi.org/10.1007/s11664-012-2009-6 A marine waste incinerator has been evaluated for waste heat harvesting using thermoelectric generators (TEG). The application has been evaluated using mathematical modeling to optimize the heat exchanger and some vital design parameters of the TEG. The calculation shows that it is possible to extract 58 kW el at a price of 6.6 US$/W from an 850-kW th incinerator when optimizing for maximum power. However, minimizing the cost, it is possible to get 25 kW el at a price of 2.5 US$/W. A trade-off between the two targets lea…
WASTE PLASTICS MANAGEMENT IN MUNICIPALITIES: LOGISTICS AND PROCESSES IN LOMBARDIA (NORTHERN ITALY)
2013
A partnership of 49 Municipalities lying in Lombardia (Northern Italy) and belonging to the District “Monza and Brianza” has entrusted the management of the Municipal Solid Waste (MSW) to two Public Companies: “C.E.M. Ambiente S.p.A.” - which owns and operates a transfer station and a multi-material centre - and “SERUSO S.p.A.”, whose single facility is set up and equipped for a high performance factory sorting of the dry fraction of the urban waste. The catchment area is populated by 448 000, living in an area of 366 km2. The management system starts with household sorting for multi-bin curbside collection; followed by hauling to selection and physical treatment facilities; and last, trans…
Dyvalocca : un projet pour l'étude des nuages bas de saison sèche sur la façade atlantique de l'Afrique centrale et de leur impact bioclimatique sur …
2020
Low-level clouds are key components of the climate but are not well represented in weather and climate models. Recently it has been shown that an extensive low-level cloud cover develops during the June-September main dry season in western equatorial Africa, from the coastal plains of Gabon and Congo-Brazzaville to the inland plateaus downstream of the low-mountain crests. Such a cloudy main dry season is unique in the moist Tropics and is likely to explain the presence of the densest and evergreen forests of Central Africa as evapotranspiration is low and the quality of light is high. The ANR-DFG funded “DYVALOCCA” project will conduct from 2020 to 2022 a field campaign, raise existing in-…
Gestions de l'eau et du développement urbain dans l'espace dijonnais :quels modes d'intégration territoriale ?
2006
Urban growth, jointed to technical networks, contributes to human pressure on water resources. In the meantime, the water French policy put management of urban development in accordance with catchments and hydrologic dynamics; that makes districts and intermunicipal groupings adopt new areas and action systems. The urban area of Dijon is located in three catchments and above a wide groundwater. This case shows urban water management gives greater place to precariousness and common character of water resources, even if institutional responses mainly concern town planning regulation.
