Analytical and multibody modeling for the power analysis of standing jumps
No full textTwo methods for the power analysis of standing jumps are proposed and compared in this article. The first method is based on a simple analytical formulation which requires as input the coordinates of the center of gravity in three specified instants of the jump. The second method is based on a multibody model that simulates the jumps processing the data obtained by a three-dimensional (3D) motion capture system and the dynamometric measurements obtained by the force platforms. The multibody model is developed with OpenSim, an open-source software which provides tools for the kinematic and dynamic analyses of 3D human body models. The study is focused on two of the typical tests used to evaluate the muscular activity of lower limbs, which are the counter movement jump and the standing long jump. The comparison between the results obtained by the two methods confirms that the proposed analytical formulation is correct and represents a simple tool suitable for a preliminary analysis of total mechanical work and the mean power exerted in standing jumps. �� 2014 �� 2014 Taylor & Francis

No full textI grammatici tra libro e testo. Il caso di Orso beneventano
No full textThe codex 1086 of the Biblioteca Casanatense of Rome, with the Adbreviatio artis gramaticae of Ursus Beneventanus, is a case study particularly significant to deepen the relationship between author, text and book: in its first part the manuscript is an 'idiografo d'autore' because it reports the text 'fired' by the author; in the second one it collects the notes of the author himself, working materials stopped at a stage of sketch or partial drafting. A reconstruction of the figure of Ursus is attempted, a grammar teacher active in Benevento in the first half of the IXth century, and the didactic nature of his manual is deepened. Finally, some reservations are proposed at the recent critical edition of Barbara Maria Tarquini
Strategies for enhancement and promotion of SiLiBA, the lithotheque of the University of Bari (Italy)
No full textGeological collections assume an undisputed importance since they gather materials for their relevance asspecific geological events or for mineral and rock group representativeness, or for historical and educationalsignificance.
SiLiBA, the lithotheque of geological cherts at the Earth and Geoenvironmental Department of the Universityof Bari Aldo Moro is an example of the scientific and educational value of Universities’ geological collections.It is composed of about 900 samples of primary and secondary geological cherts coming mainly from minesand deposits in Apulia and Basilicata (Italy) and from some regions of Croatia. The lithotheque is connected toa laboratory for the characterisation of chert samples. SiLiBA cherts have been studied by means of a non-invasive protocol (Delluniversità et al. 2019) thanks to which, through macroscopic and mesoscopicobservations, colourimetric measurements and chemical and micropaleontological analyses, a very largeamount of original data, as well as images at different scale, has been produced and collected in a database.
Naturally, for the collection dissemination a fundamental role is played by the most widespread and innovativetools, especially in the historical period we are experiencing, in which the global virtual connection of people,things and ideas is essential for continuing to interact with each other, exchange information and improvethemself, both in life and work.
With a view of economic sustainability and resource optimization and in order to create a global connectionbetween archaeologists and geologists, the collection promotion has been improved by means of a dedicatedwebsite.
It is articulated into submenus and includes sections containing archaeological information on procurementand manufacturing of cherts in the Prehistory, history of the lithotheque, publications and events and activities,including experimental archaeology laboratories and tutorials. The website focus is the section concerning the database reports, thanks to which the visitor can consult allthe data sheets, setting geographic or geological or by name criteria searching. The SiLiBA site is enriched bya section reporting the interactive 3D reconstruction of the most representative samples.
Even if the input of some data is not yet complete, the site is online and explorable. The future goal is tocreate a social profile in order to reach as many users as possible, especially in school and universitycommunities, and to publish interesting and original contents that can move people closer to geologicalcollections and to the Earth sciences and to the archaeology field
Evaluation of energy conservation opportunities through Energy Performance Contracting: A case study in Italy
No full textNon-residential buildings like healthcare ones contribute to energy consumption and cause a negative environmental impact. This is mainly due to the age of the buildings, their poor level of energy efficiency and the implementation of only a basic maintenance plan. Owing to the very limited budget available for public administrators, Energy Performance Contracting (EPC), that entails the involvement of an Energy Service Company (ESCo), can provide the entire or part of the capital needed for investments aimed at progressively increasing energy efficiency over their service life. In this paper, three acute hospitals and two community clinics built in Italy are analysed, in order to assess the economic feasibility of several energy renovation actions that can be included within EPC contracts. To this purpose, the outcomes of energy audits carried out in 2014 about these buildings are reported, which involved analyses of consumption measured over the previous three years and assessment of use profiles for the development of models to break down the overall consumption and to estimate potential savings. Diverse improvement strategies were assessed, consisting in either isolated or combined renovation actions and tested on the five buildings, whose comparison was carried out in terms of energy saving, pollution reduction and economic feasibility. As a result, the best combined renovation actions per each hospital were recommended, that included - but were not limited to - the improvement of the control and regulation of existing sub-systems without replacement, partial replacement of other sub-systems and integration of renewables. Finally, each scenario was evaluated through the payback period and other economic performance indexes in order-to assess the feasibility of the EPC framework when applied to this case study
Managing Energy Retrofit of Acute Hospitals and Community Clinics through EPC Contracting: The MARTE Project
No full textAbstractAcute hospitals and community clinics contribute to energy consumption and have a negative environmental impact. This is mainly due to the age of the buildings, a poor level of energy efficiency and a basic maintenance plan. Owing to the very limited money available for public administrators, Energy Performance Contracting (EPC), involving an Energy Service Company (ESCo), can provide the capital needed for investments aimed at increasing energy efficiency. In this paper three acute hospitals and two community clinics in Italy are analyzed prior to EPC development in order to assess the economic feasibility of retrofit strategies. The outcome of energy audits carried out in 2014, the analyses of consumption measured over the last 3 years, and the assessment of use profiles were all considered for the development of models to break down the overall consumption and to assess potential savings. Recommended improvement strategies include better insulation in envelopes, enhancement of mechanical and lighting equipment, use of renewable energy, better regulation of systems. Finally, payback periods for the most likely scenarios were evaluated
