Horizontal air-to-earth heat exchangers in Northern Italy: testing, design, and monitoring
No full textEarth heat exchange (EHX) through buried horizontal air ducts (EHXair-hor) can be an effective
passive/hybrid system to reduce heating and cooling loads in temperate climate zones. This paper shows the
results of field testing, by the authors, of a buried pipe system for a single family dwelling and the design
development of a large EHXair-hor system for a High School building. The monitoring plan for the latter is
also described. Considerations on critical aspects, such as the terrain warming effect of EHXair-hor systems
are also outlined
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Socio-presbyacusis: definition and prevention
No full textSocio-presbyacusis is a hot topic with an increasing incidence and high social costs. The main etiological factors are: genetics, smoking and drinking habits, diet, metabolic syndrome, chronic otitis and noise exposure (professional, environmental and recreative). Despite its multifactorial origin, the pathogenetic mechanism of cochlear damage is based on the increased production of Reactive Oxygen Species (ROS). The clinical characteristic feature of socio-presbyacusis is represented by slow cochlear degeneration causing a reduction of central hearing inputs. The result is a gradual social isolation of the deaf patient with a worsening of his Quality of Life. The main target of the management of socio-presbyacusis is the early diagnosis and prosthetic remediation in order to avoid patient's isolation. New preventive and remediative strategies are represented by antioxidant drugs

No full textThis paper presents a new methodology for the transient analysis of nanointerconnects, modeled as lossy and dispersive multiconductor transmission lines. The proposed model is derived from the solution of the Telegrapher's equations in the framework of the Sturm-Liouville theory. The open-ended impedance matrix is expressed in a series form as a sum of infinite rational functions, derived by the series form of the Green's function. Hence, a pole-residue rational model can be synthesized and a reduced-order model to be generated by a simple selection of dominant poles. The spectral form of the Green's function also allows to generate a rational model for the transient voltage sensitivity as well. The numerical results confirm the robustness of the proposed technique and its suitability to be adopted in the design flow of next generation nanointerconnects for signal integrity and electromagnetic compatibility purposes
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
