No full textThe main challenges of imaging for endometriosis are the detection of nonovarian disease and the evaluation of the extension of the disease into pelvic structures. Transvaginal ultrasonography (TVS) has been proposed as the first-line imaging technique because it allows extensive exploration of the pelvis. The "typical" endometrioma is a unilocular cyst with homogeneous low-level echogenicity (ground glass echogenicity) of the cyst fluid. The use of color Doppler helps avoid classifying malignancies as endometriomas, defining the presence of vascular flow in papillations. The real-time dynamic TVS examination of adhesions and pouch of Douglas (POD) obliteration, using the sliding sign technique, seems to be useful in the identification of women at increased risk for bowel endometriosis. Transvaginal ultrasound allows an accurate assessment of the vagina, particularly the areas of the posterior and lateral vaginal fornixes, the retrocervical area with torus uterinum and uterosacral ligaments, and the rectovaginal septum. The slightly filled bladder permits an evaluation of the bladder walls and the presence of endometriotic nodules which appear as hypoechoic linear or spherical lesions bulging toward the lumen, involving the serosa, muscularis, or (sub)mucosa of the bladder. Deep nodules of the rectum appear as hypoechoic lesions, linear or nodular retroperitoneal thickening with irregular borders, penetrating into the intestinal wall distorting its normal structure with the presence of few vessels observed with power Doppler evaluation. Adenomyosis can be observed with the two-dimensional (2D) TVS showing the typical myometrial features and 3D evaluation of the junctional zone. Although the sensitivity and specificity of TVS in the prediction of deeply infiltrating endometriosis and adenomyosis is high, their assessment by TVS is difficult and needs a great expertise
A Finite Element Model for Structural and Aeroelastic Analysis of Rotary Wings with Advanced Blade Geometry
No full textStructural-Aeroelastic Finite Element Modeling for Advanced-Geometry Rotor Blades
No full text"Purpose The purpose of this paper is to present the development and application of a numerical formulation for the structural dynamics and aeroelastic analysis of new generation helicopter and tiltrotor rotor blades. These are characterized by a curvilinear elastic axis, typically with the. presence of tip sweep and anhedral angles. The structural dynamics model implemented is based on nonlinear, flap-lag-torsion, rotating beam equations that. are valid for slender, homogeneous, isotropic, non-uniform, twisted blades undergoing moderate displacements. A second-order approximation scheme. for strain-displacement is adopted. Aerodynamic contributions for aeroelastic applications are derived from sectional theories, with inclusion of wake inflow models to take into account three-dimensional effects. The numerical integration is obtained through implementation within the COMSOL Multiphysics Finite-Element-Method (FEM) software code, considering the elastic axis of arbitrary curvilinear shape..
Giose Rimanelli: il punto di vista ‘nella’ guerra tra Tiro al piccione e Benedetta in Guysterland
No full textIl contributo propone una comparazione tra due romanzi di Giose Rimanelli, Tiro al piccione e Benedetta in Guysterland, che rappresentano rispettivamente l’esordio italiano e americano dello scrittore molisano. Il tema della guerra, associato a quello del punto di vista – in entrambi da intendersi sia come sguardo e percezione del protagonista sia come fattore peculiare della narrazione – permette di individuare costanti ed evoluzioni della produzione rimanelliana. In particolare, se nel primo l’esperienza della guerra civile 1943-1945 prende corpo nella vista malata dell’io narrante, rivelando la crisi di un itinerario di formazione accelerato dalla fuga dal paese natale, nel secondo a fare da sfondo al viaggio mentale di chi racconta, caotico e allucinato ancor più, sono le guerre tra gangster. Individuati vari aspetti comuni, dall’importanza della dimensione del dormiveglia a quella del passato che riemerge, il confronto mette in luce la svolta sperimentale che l’autore impresse alla propria opera negli anni Sessanta e Settanta senza recidere del tutto i legami con la poetica giovanile

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
