First analyses on a mechanical motion converter to produce electrical energy from sea wave
2020
The exploitation of sea wave opens new horizon for suppling small islanded communities. With this goal the paper propones a prototypical device for the utilization of sea wave along the coastline. The device is based on a mechanical motion conversion, from an alternative rotation into unidirectional rotation in order to run commercial generators. First evaluations are here reported, demonstrating the feasibility of this solution.

Applying systems thinking concepts in the analysis of knowledge sharing on WeChat.
2019
This research is intended to theoretically investigate and analyse the characteristics of WeChat and its effect on knowledge sharing through a systems thinking approach. As one of the most popular mobile social application in China, WeChat has social attributes and the functions of multimedia interaction platform and has been gradually used in knowledge management practice. On one hand, comparing with virtual communities of practice, WeChat provides a more open and individual environment which break free the shackles of workplace relations. On the other hand, as a user-operated media and instant messaging software, WeChat has dramatically different structure with academic social network sit…
Personal conceptions of intelligence: Cross-cultural comparisons between Portuguese and Italian students
2006
This article presents some results of an intercultural study on personal conceptions of intelligence. The sample includes 1,540 students, 811 Italians and 729 Portuguese, from both sexes and of different socioeconomic statuses, of secondary Grades 10 and 12 and of the 1st grade of several university courses in both countries. The instrument used was The Personal Conceptions of Intelligence Scale (Faria, 2003), with 26 items, translated and adapted to Portuguese and Italian. The level of education and the cultural context appear as the only variables with either principal and interaction effects on the differentiation of personal conceptions of intelligence, which are analyzed according to t…
Revisión de las formas abreviadas de la Escala de Inteligencia de Wechsler para Adultos
2016
RESUMEN: El presente trabajo tiene como objetivo presentar una revisión teórica de las principales formas abreviadas que han sido desarrolladas por varios autores a partir de las distintas versiones de la Escala de inteligencia de Wechsler para adultos que han ido surgiendo a lo largo del tiempo. El desarrollo de formas cortas ha ido creciendo en paralelo a la aparición de las nuevas versiones de la escala completa. Una forma abreviada permite estimar la capacidad intelectual con un tiempo de administración menor, por lo que puede ser de gran utilidad si el objetivo de evaluación es obtener una medida general de la capacidad intelectual.Wechsler Adult Intelligence Scale: Review of short for…
Short forms of the Wechsler adult scales: a systematic review
2020
espanolIntroduccion.Desde la aparicion de la primera escala WAIS, ha habido un intento generalizado por parte de investigadores/as en la evaluacion de las habilidades cognitivas por encontrar formas abreviadas que faciliten la practica clinica de los/as profesionales en aquellas situaciones en las que las condiciones, bien por el tiempo disponible o por las caracteristicas clinicas de los/as pacientes, no aconsejan utilizar un ins-trumento extenso. Objetivo.Llevar a cabo una revision sistematica de las formas breves de hasta cuatro subtests elaboradas a partir de las escalas WAIS-III y WAIS-IV. Metodologia.Busqueda de informacion en la base de datos PsycINFO y revision sistematica de la inf…
Rosyjskie siły lądowe i flota bałtycka w 1715 i 1719 roku w świetle raportów brytyjskich
2020
Wielka wojna północna oznaczała zmierzch starych potęg takich, jak Szwecja czy Rzeczypospolita i narodziny nowej - Rosji cara Piotra I. Przeprowadził on w państwie głębokie reformy oraz zmodernizował i unowocześnił siły zbrojne, tworząc bałtycką flotę wojenną. Zmiany te nie uszły uwadze ambasadorów obcych państw, w tym oczywiście Wielkiej Brytanii, którzy raportowali o nich do centrali. Sporządzali także zestawienia sił zbrojnych Rosji, w tym marynarki oraz umieszczali przy takiej okazji trafne spostrzeżenia dotyczące żołdu czy werbunku marynarzy. Kilka z nich będzie przedmiotem analizy, a dane które można z nich odczytać będą mogły świadczyć o rozwoju carskich sił zbrojnych.
Sea Wave Energy. A Review of the Current Technologies and Perspectives
2021
The proposal of new technologies capable of producing electrical energy from renewable sources has driven research into seas and oceans. Research finds this field very promising in the future of renewable energies, especially in areas where there are specific climatic and morphological characteristics to exploit large amounts of energy from the sea. In general, this kind of energy is referred to as six energy resources: waves, tidal range, tidal current, ocean current, ocean thermal energy conversion, and saline gradient. This review has the aim to list several wave-energy converter power plants and to analyze their years of operation. In this way, a focus is created to understand how many …
An Evaluation Matrix to Compare Computer Hydrological Models for Flood Predictions
2020
In order to predict and control the impacts of floods in torrents, it is important to verify the simulation accuracy of the most used hydrological models. The performance verification is particularly needed for applications in watersheds with peculiar climatic and geomorphological characteristics, such as the Mediterranean torrents. Moreover, in addition to the accuracy, other factors affect the choice of software by stakeholders (users, modellers, researchers, etc.). This study introduces a &ldquo
Regular Strength and Sprint Training Counteracts Bone Aging: a 10- year Follow-up in Male Masters Athletes
2021
According to cross-sectional and interventional studies, high-intensity strength and impact-type training provide a powerful osteogenic stimulus even in old age. Longitudinal evidence on the ability of high-intensity training to attenuate age-related bone deterioration is currently lacking, however. This follow-up study assessed the role of continued strength and sprint training on bone aging in 40- to 85-year-old male sprinters (n=69) with long-term training background. pQCT-derived bone structural, strength and densitometric parameters of the distal tibia (5% distal-proximal tibia length) and tibial midshaft (50% length) were assessed at baseline and after 10 years. The groups of well-tra…
