Postural adjustments and perceptual responses of Nordic running: concurrent effects of poles and irregular terrain
No full textPurpose: In the natural environment, humans must continuously negotiate irregular and unpredictable terrain. Recently, the poles have been extensively used during trial running events. However, we know little about how humans adjust posture and bilateral coordination to use poles in irregular terrain. Here, we compared kinematics, bilateral coordination and perceptual responses between regular (compact dust) and irregular terrain (medium-length grass) during running at preferred speed with and without poles. Methods: In this transversal observational study, thirteen young healthy adults (8 men; mean ± SD; age 29.1 ± 8.0 years, body mass 76.8 ± 11.4 kg; height 1.75 ± 0.08 m) were evaluated during running at a self-selected comfortable speed with and without poles on regular and irregular terrains. Results: Our results show that, despite more flexed pattern on lower-limb joints at irregular terrain, the usage of poles was not enough to re-stabilize the bilateral coordination. Also, the perceived exertion was impaired adding poles to running, probably due to more complex movement pattern using poles in comparison to free running, and the invariance in the bilateral coordination. Conclusion: Besides the invariability of usage poles on bilateral coordination and lower-limb kinematics, the runners seem to prioritize postural stability over lower limb stiffness when running in medium-length grass given the larger range of ankle and knee motion observed in irregular terrain. Further investigations at rougher/hilly terrains will likely provide additional insights into the neuromotor control strategies used to maintain the stability and on perceptual responses using poles during running
Is Education the Best Tool to Fight Disinformation?
No full textEducation positively affects human development, while disinformation hinders human activities. However, in previous economic studies on disinformation, the role of education is, at the best, implicit. This theoretical and empirical paper, therefore, aims to put education at the centre of the disinformation problem. Precisely, a theoretic model of information search is used to show the negative effect of disinformation on market outcomes, while a survey study on graduates in Italian universities is used to highlight the role of education in reducing the negative impact of disinformation. Two are the main results of this analysis. First, in the presence of disinformation, the auditing of the sources of information is a necessary activity. Second, education is the most effective tool for reducing the auditing cost. It follows that the investment in education is the best economic and social policy to fight disinformation
Comparative study of steam, organic Rankine cycle and supercritical CO2 power plants integrated with residual municipal solid waste gasification for district heating and cooling
No full textAmong the different waste-to-energy solutions, gasification is considered a promising option and an alternative to landfilling of residual municipal solid waste (RMSW). Therefore, the potential of RMSW air gasification in combination with three different power cycles for district cooling and heating applications is investigated. The model of a fluidized bed air gasifier developed in Aspen Plus is integrated with the models of steam turbine (ST), organic Rankine cycle (ORC), and supercritical CO2 (sCO2) Brayton cycle power plants for the combined cooling, heating, and power production in district networks.
The results of the numerical study show that the ST power plant provides higher electrical power compared to the other systems, while sCO2 exhibits better thermal power and the maxima combined energy conversion efficiency. In between, ORCs prove to be a reliable and flexible solution for varying RMSW compositions and temperature levels of the district network. The size of the district network strongly varies with scenarios and in the best case, more than 1,400 residential buildings can be connected to the trigeneration plant considering 20 ktons/year of RMSW input to the gasifier

Le regolarizzazioni previste dall’art. 182 c.p.c. tra interventi ermeneutici della giurisprudenza di legittimità e modifiche normative
No full textIl d.leg. 149/22, nel modificare il comma 2 dell’art. 182 c.p.c., ha ampliato il perimetro delle regolarizzazioni che operano con efficacia retroattiva, ricomprendendovi anche l’ipotesi di mancanza della procura al difensore. Lo studio si propone di analizzare la compatibilità, a livello sistematico, della nuova previsione normativa con i casi di inesistenza, materiale e giuridica, della procura alle liti
