Geological setting of the Bagno Vignoni area (northern side of the Mt. Amiata geothermal area, Italy): collisional structures recorded in the Tuscan Nappe
No full textGeological studies carried out in the Bagno Vignoni area (southern Tuscany) for the realisation of the new Geological Map of Tuscany (1:10,000 scale), and the interpretation of the Cro.P.18 crustal seismic line, highlighted new structural data for the Tuscan Nappe occurring on the northern side of the Mt. Amiata geothermal area. The Tuscan Nappe was affected by polyphase tectonics, as documented by structural data mainly detected from map-scale and microstructural analyses. The Tuscan Nappe in the Bagno Vignoni area consists of small outcrops emerging from Ligurian l.s. Units, mainly composed of the <> Unit. The Tuscan Nappe is typified by repetitions of its stratigraphical succession due to the presence of imbricate thrusts. They are associated with a collisional, southeast-verging thrust system which produced three Tuscan Nappe subunits, highlighted by field mapping and borehole stratigraphy. The lowermost outcropping subunit (SU3) is composed of the stratigraphical succession ranging from the <>. Fm. to the <> Fm.; the overlying SU2 is characterised only by the <> and <> Fms., whereas the uppermost SU1 is composed of the <> Fm. and the <> Fm. The Tuscan Nappe subunits stack was later deformed by Early-Middle Miocene low-angle normal faults which produced widespread tectonic elision between the thickened Tuscan Nappe and Ligurian Units. In fact, in the study area, the <> Unit, mainly composed of <> and <> Fms., lies on different Tuscan Nappe formations, suggesting the tectonic elision of the uppermost Tuscan Nappe formations, of the Subligurian Unit and of the lowermost formations of the <> Unit. On the whole, Tuscan Nappe collisional structures occur-ring in the Bagno Vignoni area represent relict structures preserved during extensional tectonics. The evidence also demonstrates the occurrence of collisional structures in the northern part of the Mt. Amiata geothermal area, as well as in the western and eastern sides (Mt. Aquilaia-Mt. Buceto and Poggio Zoccolino-Campiglia d'Orcia)
Terme e termalismo tra Valdorcia e Amiata. Uno sguardo storico su Bagno Vignoni e Bagni San Filippo
No full textLo scritto si concentra sulla straordinaria presenza di manifestazioni idrominerali che caratterizza il Senese e la Valdorcia, che fu sicuramente conosciuta e sfruttata fin dall’età antica. Si traccia l'evoluzione geostorica delle strutture termali presenti nel territorio della Valdorcia e dell'Amiata, con particolare attenzione per Bagno Vignoni e Bagni di San Filippo
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Contractivity of a genetic circuit with internal feedback and cell-to-cell communication
No full text[EN] We consider a realistic model of the synthetic gene circuit combining cell-to-cell communication system via quorum sensing, and a synthetic repressible promoter implementing intracellular negative feedback control. The circuit has been shown to increase robustness with respect to both extrinsic and intrinsic noise elsewhere. As a first step towards an analytic analysis, in this paper we use contraction theory to perform a stability analysis. From it, we infer the components of the circuit most affecting the rate of contractivity, using biologically sensible values of the circuit parameters.This research was partially funded by grant FEDER-CICYT DPI2014-55276-C5-1-R.

Monitoring of pregnancy complicated by maternal-fetal isoimmunization. A comparison between two clinical protocols
No full textAIM:
Invasive techniques such as amniocentesis and cordocentesis are used for the diagnosis and treatment of fetus at risk for anemia due to maternal red-cell alloimmunization. The purpose of this study was to determine the value of non invasive measurements of the peak velocity middle cerebral artery in the fetus (PVMCA) for the diagnosis of fetal anemia.
METHODS:
From 1996 to September 2002, we studied 23 pregnancies with anti D title >1:32. In the 1(st) group of 11 women (from 1996 to 1999) fetal anemia was detected by invasive techniques (amniocentesis and cordocentesis). In the 2(nd) group of 12 women (from 1999 to 2002) fetal anemia was suspected on the basis of PVMCA. When PVMCA was significantly increased, cordocentesis was performed in order to rule out fetal anemia and to provide in utero transfusions.
RESULTS:
In the 1(st) period we performed 23 invasive techniques (7 amniocentesis and 16 cordocentesis) in 11 women, but we identified fetal anemia only in 4 cases. In the 2(nd) period we performed only 2 cordocentesis in women in which PVMCA was increased; the blood sampling confirmed fetal anemia in both cases.
CONCLUSION:
PVMCA and fetal hematocrit are highly significantly correlated: high values of PVMCA are associated with fetal anemia. Doppler velocity of PVMCA is related to fetal anemia with positive predictive value 100% and negative predictive value 100%. The middle cerebral artery blood velocity is a non invasive technique for detecting anemia in pregnancies complicated by alloimmunization
Variations on the Author
No full text“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
Tutela ambiental en la jurisprudencia del Tribunal Superior de Justicia de la provincia del Neuquén.
No full textEl objetivo del presente trabajo es sistematizar los criterios más relevantes
adoptados por el Tribunal Superior de Justicia de la Provincia del Neuquén en
materia de protección ambiental, a partir de la reforma constitucional provincial
del año 2006 hasta la actualidad, desde un enfoque tripartito: constitucional
(englobando los decisorios referentes al deslinde de competencias para ejercer
el poder de policía ambiental), procesal (abarcando los precedentes relativos a
cuestiones de competencia y legitimación en materia de procesos ambientales) y
procedimental (agrupando los fallos donde se ventilaron cuestiones suscitadas
durante el procedimiento administrativo sancionador).Todo ello, en el contexto
de las obligaciones estatales específicas que emergen de los textos
constitucionales, internacionales y de la legislación aplicable en la materia.Fil: Vignoni, Lucía Juliana Virginia. Universidad Nacional del Comahue. Facultad de Derecho y Ciencias Sociales; Argentina
