Jääkiekkoilijoiden maksimaalisen luistelunopeuden ja anaerobisen kestävyyden ennustaminen H/M -suhteen avulla
2008
Tutkimuksen tarkoituksena oli selvittää voidaanko Hoffman –refleksin ja M –aallon välisen suhteen (H/M –suhteen) avulla ennustaa jääkiekkoilijoiden maksimaalista luistelunopeutta (Vmax) ja anaerobista kestävyyttä (Vanak). Kestävyyspainotteinen harjoittelu voi kasvattaa hitaiden motoristen yksikköjen kokoa ja vastaavasti voimaharjoittelun on todettu lisäävän nopeiden motoristen yksikköjen määrää. Tutkimuksen koehenkilöinä oli 16 miespuolista jääkiekkoilijaa, joista 8 oli SM –Liigatason pelaajaa ja 8 B –juniori-ikäistä pelaajaa. Jokaiselta koehenkilöltä mitattiin maksimaalinen luistelunopeus ja anaerobinen kestävyys jäällä luistellen. Lisäksi mitattiin antropometria ja voimaominaisuudet. Koeh…
Language acquisition through interaction between gamers in digital gaming environments
2014
Internetin kautta pelattavat moninpelit tarjoavat monenlaisia mahdollisuuksia harjoitella Englannin kielitaitoa, sekä käyttää sitä hyväksi erilaisissa kommunikointitilanteissa. Pelien hyötyä kieltenoppimisessa on jo jonkin verran tutkittu, mutta tutkimus rajoittuu suurelta osin itse pelien sisältöihin. Lähivuosina internetin kautta pelaaminen yhdessä toisten pelaajien kanssa on yleistynyt, mikä on avannut keskustelua myös pelien interaktiivisuuden vaikutuksista kielitaitoon. Internetissä tapaa usein pelaajia monista erilaisista kulttuureista ja taustoista, mikä rikastuttaa kielikulttuuria sekä mahdollistaa kielenkäytön harjoittelun matalan kynnyksen tilanteissa. Suomalaiset pelaavat interne…
Comparison of a near-infrared reflectance spectroscopy system and skin conductance measurements for in vivo estimation of skin hydration: a clinical …
2017
Diffuse reflectance spectroscopy system was developed for estimation of skin hydration in the near-infrared spectral range of 900-1700 nm. Experimental setup consisted of a near-infrared spectrometer, Y-type fiber optics probe with 1 detection and 6 illumination fibers, halogen-tungsten light source and a PC. By analyzing diffuse reflectance spectrum, a parameter representing skin hydration by performing baseline correction and calculating the area under the 1450 nm water absorption maximum is proposed. A clinical study was performed acquiring data of skin hydration of 39 patients' forearm skin. Results of the developed system are compared to results obtained by a commercial device based on…
La radicalidad del mal banal
2002
El concepto de ‘banalidad del mal’ fue introducido por Hannah Arendt a fin de caracterizar una forma inédita de perversidad que ella vio encarnada en Adolf Eichmann y otros criminales nazis. Arendt consideraba que esa forma de perversidad estaba muy alejada de la noción de ‘mal radical’ que Kant había acuñado y la propia Arendt había empleado en trabajos anteriores. El objetivo principal del artículo es mostrar que hay más afinidades entre el mal radical kantiano y la banalidad del mal de lo que la propia Arendt reconoce. ‘Banality of evil’ was a concept introduced by Hannah Arendt in order to characterize a new form of wickedness embodied in people as Adolf Eichmann and others nazis crimin…
A simple methodology for comparing cost-benefit of traditional, green and cool roofs
2019
Energy policy makers, architects and researchers, when designing new buildings or rehabilitating the existing ones, are engaged in the attempt of limiting the energy needs for climatization (NZEB buildings) and the environmental pressure exerted by buildings (EU Climate Action). The pursuit of this demanding assignment calls for innovative solutions in conceiving the building envelope and its energy systems. Recently, among the most effective tools for improving the energy and environmental performances of buildings, the technical interventions regarding the roofs are gaining a rising attention. Indeed, covers of buildings are responsible of a relevant part of their energy losses and, on th…
Sustainable vehicle routing based on firefly algorithm and TOPSIS methodology
2019
Abstract In a sustainable management of logistics, transportation plays a crucial role. Traditionally, the main purpose was to solve the Vehicle Routing Problem minimizing the cost associated with the travelled distances. Nowadays, the economic profit cannot be the only driver for achieving sustainability and environmental issues have to be also considered. In this paper, to satisfy the intricate limits involved in real vehicle routing problem, the study has been structured considering different types of vehicles in terms of maximum capacity, velocity and emissions, asymmetric paths, vehicle-client constraints and delivery time windows. The firefly algorithm has been implemented to solve th…
Performance Improvement of a Drag Hydrokinetic Turbine
2021
Hydropower is at present in many locations, among all the other possible renewable energy sources, the best one for net cost per unit power. In contrast to traditional installation, based on water storage in artificial basins, free flow river turbines also provide a very low environmental impact due to their negligible effect on solid transport. Among them, kinetic turbines with vertical axis are very inexpensive and have almost zero impact on fish and local fauna. In application to tidal waves and sea waves, where vertically averaged velocities have alternate direction, a Savonius rotor also has the advantage of being productive during the whole time cycle. In this work, the effect of an u…
Application of EMI and FDR Sensors to Assess the Fraction of Transpirable Soil Water over an Olive Grove
2018
Accurate soil water status measurements across spatial and temporal scales are still a challenging task, specifically at intermediate spatial (0.1–10 ha) and temporal (minutes to days) scales. Consequently, a gap in knowledge limits our understanding of the reliability of the spatial measurements and its practical applicability in agricultural water management. This paper compares the cumulative EM38 (Geonics Ltd., Mississauga, ON, Canada) response collected by placing the sensor above ground with the corresponding soil water content obtained by integrating the values measured with an FDR (frequency domain reflectometry) sensor. In two field areas, characterized by different soil clay conte…
Enhancing a Transition to a Circular Economy in the Water Sector: The EU Project WIDER UPTAKE
2021
A novel approach for resource recovery includes forward osmosis (FO) as a concentration step in municipal wastewater treatment. The current study investigates different pre-treatment strategies including biological treatment with a moving-bed bioreactor (MBBR) at different loading rates and particle removal by filtration and sedimentation. Membrane performance and recovery potential for energy and nutrients were investigated in laboratory-scale FO experiments in batch mode using pre-treated municipal wastewater as feed and 35 g/L NaCl as a draw solution. Initial water fluxes were in the range of 6.3 to 8.0 L/(m2·h). The baseline fluxes were modelled to account for flux decline due to concen…
The Coaching Maps as a Tool for Developing Reflectivity in Organisations
2019
Our view of organizations, labour and the competencies of managers will soon need to change. In the postmodern and post-Fordist world, economy and organizations function differently than they did in the 20th century. Workers and managers will have to face new expectations. Not only has reflectivity become one of the key organisational factors; it is also taught, learnt and shaped. Drawing on an authoethnographic model and action-research, authors of this paper provide an education and development tool that managers and workers can use to develop and trigger reflectivity. Picture ethnography, coaching philosophy and hermeneutics are theoretical bases for the construction of a new model of se…
