An Original Mid-Nineteenth Century Scientific Instrument in Italy: Vincenzo Vignola’s Induction Coil  [PDF]
Roberto Mantovani
Advances in Historical Studies (AHS) , 2015, DOI: 10.4236/ahs.2015.42009
Abstract: It is well known that the induction coil was invented in the mid-1830s, but its most significant improvements were made between the late 1830s and 1851. During these years a lot of research was aimed at improving the functionality and effectiveness of the device. In Italy one of the very first attempts at improvement was made first by an instrument maker from Milan, Carlo Dell’Acqua, and secondly, by a priest from Verona, Vincenzo Vignola. In 1851, Vignola was awarded the gold medal from the Academy of Agriculture, Arts and Commerce of Verona for having introduced important and useful changes to the Callan electromotor. This event opened up the discovery of a number of very interesting, unpublished hand-written documents, as well as the discovery of the device itself, provided with an almost unique self-acting commutator-interrupter system. Today this apparatus is preserved at the Physics Museum “Antonio Maria Traversi” in Venice.

Abstract: it is about a research of qualitative nature, whose objective was to identify the representation of the professor on the formation of the nurse. were interviewed 22 teaching nurses of the course of graduation in nursing of two institutions of superior education of the city of curitiba (brazil). the ethics precepts were respected, and the project was approved by the committee of the sector of sciences of health of the federal university of the paraná (brazil). the interviews were recorded and transcribing, and the reports, analyzed by the technique of the analysis of content. the theme that emerged of the speeches was: the representation of the profile of the nurse formed by the institution. this theme made possible the composition of three categories: critical-reflexive nurse, humanistic and autonomous worker. we consider that the representation of the professors about the formation of the nurse more moves them away from the traditional paradigm, approaching them of the emergent paradigm that considers the methodology of learning to learn, and that their representations are anchored in the current law and in the mission of the university: education, research and extension.
GABA-B receptors in the PNS have a role in Schwann cells differentiation?
Luca F. Castelnovo,Cristina Mantovani,Valerio Magnaghi
Frontiers in Cellular Neuroscience , 2013, DOI: 10.3389/fncel.2012.00068
Abstract: γ-aminobutyric acid type B (GABA-B) receptor mediates the inhibitory transmission of γ-aminobutyric acid in the mammalian nervous system, being present in neurons and also in glial cells. Recently the presence of GABA-B has been demonstrated in Schwann cells (SC) suggesting its contribution in regulating the cell fate, maturation, and plasticity. Here, we further support the functional presence of GABA-B receptor in SC plasma membrane. By confocal microscopy immunofluorescence we provide evidences that GABA-B localization on the cell elongated processes correlates with the morphological changes occurring in the differentiated SC. In vivo most of the GABA-B receptors seem to be present in non-myelinating SC, which are committed to ensheath the nociceptive fibers. Therefore, we argue that GABA-B receptors do not control exclusively the in vivo differentiation yielding the myelinating SC, but are also fundamental in regulating the SC plasticity versus the non-myelinating state. Data from the literature and our recent findings corroborate the role of the GABAergic system and GABA-B receptors in the peripheral nervous system, opening new perspectives on the mechanisms controlling the differentiation of SC.
Neutrinos and Energetics of the Earth

Physics , 2002, DOI: 10.1016/S0370-2693(03)00193-X
Abstract: We estimate terrestrial antineutrino and neutrino fluxes according to different models of Earth composition. We find large variations, corresponding to uncertainties on the estimated $U$, $Th$ and $K$ abundances in the mantle. Information on the mantle composition can be derived from antineutrino flux measurements after subtracting the crust contribution. This requires a good description of the crust composition in the region of the detector site. Measurements of terrestrial antineutrinos will provide a direct insight on the main sources of Earth's heat flow.

Mendes, Felismina Rosa Parreira;Mantovani, Maria de Fátima;
Revista Brasileira de Enfermagem , 2010, DOI: 10.1590/S0034-71672010000200007
Abstract: this research study, with a qualitative approach was carried out aiming to identify nurses' representation on current professional dynamics, evolutionary landmarks and the future outlook for portuguese nursing with twenty nurses from évora, portugal, in april / may of 2009, through narrative testimony. qualification obtained along the years as well as the nurses' association were mentioned as the central representative pillars in order to build up professional identity. autonomy is part of daily caring routine, however hegemonic power issues in the health team still ground nurses' action and underpin their self and peer professional and social recognition. future outlook addresses issues such as employment, career uncovering hope for some and uncertainty for others.

Abstract: nurses work within the interface of the population's process of falling ill and of occupational diseases. in this setting, chronic diseases are evidenced, and they affect the work process. the purpose of this study was to identify, in nurses, the measures used to prevent health problems in the presence of a chronic disease, analyze the relation between their knowledge and attitudes toward chronic diseases, and the relation of risk factors with their work process. this is a quantitative and descriptive study, involving 23 nurses with chronic diseases, representing 76.6% of the 30 nurses diagnosed with a chronic illness at a federal hospital, 22 of whom are women. it was observed that the nurses comply with the treatment proposed for their disease and have effective strategies to cope with the fact of falling ill, changing their lifestyles. furthermore, they reported there were factors in their work environment that contribute to worsen their illness.

Abstract: This paper presents the results of a broad, transversal, observational survey on the social cost of female urinary incontinence in the general female population, resident in the ASL3-Monza area. In this population, in an 18- 65 year old age group, the prevalence of U.I. observed is 28.5% (LIFE cases) and 18.6% (YEAR cases). The total number of incontinent women in the ASL3-Monza area and in the Lombardy Region can be estimated as follows: - ASL3-Monza 125,288 “LIFE” cases, 81,767 (18.6% of 439,609) “YEAR” cases. - Lombardy Region 1,119,480 “LIFE” cases, 730,608 (18.6% of 3,928,709) “YEAR” cases. In the light of the data collected, we can estimate that in the Lombardy Region and in the ASL3-Monza area, at least 379,600 (52% of 730,608) and 42,518 (52% of 81,767) incontinent women use protection and 175,200 (24% of 730,608) and 19,624 (24% of 81,767) consider using a pad to be the only useful solution to the problem. The “estimated” mean/annual cost per woman in an incontinent population with characteristics similar to those of the general female population of the ASL3-Monza is € 358,03, for a mean/life cost per woman of € 11.099,20.When there is no effective treatment of the symptom, we can estimate the following total cost/life in the ASL3-Monza area to be: 65,414 x 31 x € 358,03 = € 726.025.407. If the symptom disappears and the treatment is effective, this is also an advantage, apart from the obvious requirement for public health related to it, from a strictly pharmacological-economic point of view. The estimated total/life cost for the treatment (with the most effective medical, rehabilitative and/or surgical therapy available today) of a sample of 1,000 incontinent women of the ASL3- Monza area is significatively lower than the total cost/life expected in the case of persistence and “assistance” of the symptom: € 4.502.812,10 vs. € 23.451.270,02. Despite the methodological limits of a pilot study (single centre collection of data, limited samples, analysis of “theoretical” populations), from the data collected it appears clear that the more incisive and determined the strategy of information and education, and the fuller and earlier the diagnosis, the more significative the social- economic, as well as the psycho-social saving.

Abstract: Endoscopic treatment of urinary incontinence is based on the use of injectables. We use collagen (Contigen-Bard) to make the bladder neck narrower in order to ensure dynamic continence and avoid obstruction. Gax collagen is highly purified, hardly viscous bovine dermal collagen, cross-linked with glutaraldehyde in saline solution. The possible approaches for the endoscopic collagen implant are: perineal, paraurethral and transurethral, which is our choice. We are in favour of repeated injections in scheduled steps with a minimal dose: 5 ml injected transurethrally in the positions 5 and 7 every 2 months, three times: 24 patients (18 women and 6 men) average age 58, underwent the treatment and were checked with a twelve months follow-up. Effectiveness was complete in 12 women and 3 men, a significant improvement of the quality of life was reported in the other patients.
Validation of landslide hazard assessment by means of GPS monitoring technique – a case study in the Dolomites (Eastern Alps, Italy)

Natural Hazards and Earth System Sciences (NHESS) & Discussions (NHESSD) , 2007,
Abstract: In the last years a research project aimed at the assessment of the landslide hazard and susceptibility in the high Cordevole river basin (Eastern Dolomites, Italy) have been carried out. The hazard map was made adopting the Swiss Confederation semi-deterministic approach that takes into account parameters such as velocity, geometry and frequency of landslides. Usually these parameters are collected by means of geological and morphological surveys, historical archive researches, aerophotogrammetric analysis etc. In this framework however the dynamics of an instable slope can be difficult to determine. This work aims at illustrating some progress in landslide hazard assessment using a modified version of the Swiss Confederation semi-deterministic approach in which the values of some parameters have been refined in order to accomplish more reliable results in hazard assessment. A validation of the accuracy of these new values, using GPS and inclinometric measurements, has been carried out on a test site located inside the high Cordevole river basin.

Nonlinear Processes in Geophysics (NPG) , 2003,
Abstract: In this paper we test different approaches to the statistical post-processing of gridded numerical surface air temperatures (provided by the European Centre for Medium-Range Weather Forecasts) onto the temperature measured at surface weather stations located in the Italian region of Puglia. We consider simple post-processing techniques, like correction for altitude, linear regression from different input parameters and Kalman filtering, as well as a neural network training procedure, stabilised (i.e. driven into the absolute minimum of the error function over the learning set) by means of a Simulated Annealing method. A comparative analysis of the results shows that the performance with neural networks is the best. It is encouraging for systematic use in meteorological forecast-analysis service operations.
