Aprendiendo Vibraciones Mec´anicas con Wolfram Mathematica
2015
[EN] Mechanical vibrations as subject can be found within many Engineering and Science Degrees. To achieve that the students understand the mathematics and its physical interpretation is the objective we should get as docents. In this paper we describe how to create a simple graphical model of a single degree of freedom vibrating system allowing us to visualize concepts like above concepts damping, resonance or forced vibrations. For that, we use the popular symbolic software Wolfram Mathematica with which, without an excessive programming complexity, we can obtain a very satisfactory visual model capable to move itself, controlled by parameters. In addition, the model incorporates the curv…
Instructor Presence in a Virtual Classroom
2021
Abstract Synchronous online learning platforms have been used actively during the COVID-19 period. They have opened possibilities for online learning and interaction, but have also posed new challenges for instructors. This article provides insights into one teacher’s interactions and examines how the instructor presence is expressed in the teachers’ activities in virtual classrooms in higher education. Instructor presence is investigated using the social and teaching presence indicators of the community of inquiry (CoI) framework. Twelve hours of interactions across six online classes were recorded, transcribed, and analysed using content analysis. The findings suggest that indicators of t…
Synthetic environmental appraisal of waste management system: an application to the Sicilian region
2004
This paper addresses the problem of synthetically evaluating the environmental performances of urban solid waste systems. This, in fact, represents a crucial point in the management process of complex systems that local administrations are called to cope with, in order to provide decisions about policy options that involve different issues characterising the quality of life of people. Suitable methods of evaluation are clearly required for this aim. This work introduces the dashboard of sustainability and the ecological footprint approaches as aggregate indicators of the performances of solid waste management systems. The methods have been selected due to their intrinsic simplicities, provi…
Cambios en la activación electromiográfica de la musculatura de codo en sujetos sanos comparada con la activación muscular en sujetos con tendinopatí…
2021
La tendinopatía es uno de los problemas de tendón más frecuente de lesión en la actualidad. En el caso de miembros superiores, la alteración en los tendones es bastante significativa tanto en deportistas como en personas que no practican deporte. Sin embargo, hay pocos estudios que reflejen cómo repercute esto en las personas que lo padecen. Objetivos: el objetivo de este estudio es examinar y comparar la actividad electromiografia, la fuerza y la calidad de vida en personas con alteración tendinosa epicondílea del músculo extensor corto de carpo entre personas sanas, además de comprobar el efecto de la punción seca como rama de tratamiento en la actividad muscular, fuerza y dolor. Material…
An integrated and shared approach to sea of the regional town master plan of Sicily
2006
The work addresses one of the most important problems in contemporary environmental land planning. Already existing procedures, in fact, must now conform to the new requirements imposed by the recent national and international regulations and standards that call for a more conscious approach to the use of natural resources. Strategic Environmental Assessment (SEA), for example, takes into account, the different effects of a plan in various fields such as the environment, the economy and the development. This obviously calls for global analysis tools that could help administrators, stakeholders and technicians in the decision-making process of such complex systems. SEA of the Town Master Pla…
Exact mechanical models of fractional hereditary materials
2012
Fractional Viscoelasticity is referred to materials, whose constitutive law involves fractional derivatives of order β R such that 0 β 1. In this paper, two mechanical models with stress-strain relation exactly restituting fractional operators, respectively, in ranges 0 β 1 / 2 and 1 / 2 β 1 are presented. It is shown that, in the former case, the mechanical model is described by an ideal indefinite massless viscous fluid resting on a bed of independent springs (Winkler model), while, in the latter case it is a shear-type indefinite cantilever resting on a bed of independent viscous dashpots. The law of variation of all mechanical characteristics is of power-law type, strictly related to th…
Taxonomic review of the fungal-inhabiting plant bug genera Bothriomiris and Dashymenia (Hemiptera: Heteroptera: Miridae: Cylapinae: Bothriomirini), w…
2016
The two closely related and frequently confused genera of the fungal-inhabiting plant bug subfamily Cylapinae, Bothriomiris Kirkaldy, 1902 and Dashymenia Poppius, 1910 are redefined and reviewed. Two new species of Dashymenia, D. artchawakomi, new species and D. gorczycai, new species, are described from Thailand. Bothriomiris capillosus Yasunaga, 2000 and B. yakushima Yasunaga & Miyamoto, 2012 are transferred to the genus Dashymenia Poppius, and a revised key to the two genera is provided. Color habitus images of the adults are given for Dashymenia artchawakomi, D. capillosa, and D. gorczycai. The male genitalic structures of the following species are illustrated: Bothriomiris ernsti Yasun…
Traditional Dietary Patterns and Risk of Mortality in a Longitudinal Cohort of the Salus in Apulia Study
2020
There is still room for further studies analyzing the long-term health impact of specific dietary patterns observable in regions belonging to the Mediterranean area. The aim of the study is to evaluate how much a diet practiced in southern Italy is associated to a risk of mortality. The study population included 2472 participants first investigated in 1985, inquiring about their frequencies of intake of 29 foods using a self-administered questionnaire covering the previous year. The population was followed up for mortality until 31 December 2017. Cox-based risk modeling referred to single foods, food groups, the results of principal component analysis (PCA), and a priori indexes. Single foo…
"a priori" Dietary Patterns and Cognitive Function in the SUN Project
2019
<b><i>Objectives:</i></b> To study and compare associations of 5 dietary patterns – Mediterranean dietary pattern (MDP), Dietary Approaches to Stop Hypertension (DASH), Mediterranean-DASH Intervention for Neurodegenerative delay (MIND), Alternative Healthy Eating Index (AHEI-2010), and a pro-vegetarian diet (PVD) – with cognitive function. <b><i>Patients and Methods:</i></b> A subgroup of 806 participants from the “Seguimiento Universidad de Navarra”(SUN) cohort of university graduates, &#x3e;55 years old, was interviewed with the validated Spanish Telephone Interview for Cognitive Status (STICS-m) at baseline and after 2 and 6 years. For …

2020
Abstract Study Design Cross-sectional study. Introduction There is a lack of information on the measurement properties of patient-reported upper extremity instruments and their association to health-related quality of life (HRQoL). Purpose of the Study This study aimed to examine and compare the measurement properties and construct validity of the Disabilities of Arm, Shoulder, and Hand (DASH) Instrument and the Michigan Hand Questionnaire (MHQ) using a heterogeneous sample of patients with hand and wrist problems. Methods Two hundred fifty consecutive patients visiting a general orthopedic outpatient clinic due to various hand/wrist problems were invited to participate in the study. A tota…
