BR, SP, Campos do Jordão, PECJ, Córrego Casquilho (22 ° 39 ’ 49 ”S, 45 ° 27 ’04”W), 1 m, 26 /XI/ 1986, CGF. Remarks. This species was described from the Boracéia Biological Station. In PECJ, a single male was collected with a beating sheet. It may be recognized by the lighter window in the forewings and by the penial armature, with its large ventral vesicles, large arching sclerotized shoulders and the short gonopore tube. The forewing length is 9.1 mm.Published as part of Froehlich, Claudio G., 2010, Anacroneuria (Plecoptera, Perlidae) from the Mantiqueira Mountains, São Paulo State, Brazil, pp. 55-68 in Zootaxa 2365 on page 68, DOI: 10.5281/zenodo.27576

Estetica Funzione Postura
No full textTutte le riabilitazioni restaurative e protesiche dovrebbero tener conto delle problematiche occlusali, gnatologiche e posturali del paziente. La posizione mandibolare e l' occlusione giocano un ruolo determinante nel mantenimento dell' equilibrio muscolo-scheletrico e posturale dell' organismo. Se si altera questo equilibrio si possono manifestare problematiche articolari o muscolari in distretti anche molto lontani dalla bocca con sintomatologie spesso importanti.Attualmente, a differenza di qualche anno fa, per prevenire e/o curare queste patologie l' odontoiatra ha a disposizione nuovi mezzi diagnostici e moltissimi nuovi materiali da restauro e protesici.Tutti questi nuovi materiali in genere hanno qualita' estetiche elevatissime per cui la scelta deve essere fatta in base alle loro caratteristiche meccanico-fisiche.Oggi l' odontoiatra ha la possibilita' di scegliere di volta in volta, a partita' di proprieta' estetiche, il materiale piu' adatto alla specifica situazione clinica e all' occlusione del paziente
Il sonno e i sogni nel De admirandis di Giulio Cesare Vanini.
No full textGiulio Cesare Vanini, nel Dialogo LX del De admirandis, tratta il problema del sonno e dei sogni sia dal punto di vista fisiologico, sia dal punto di vista psicologico. In particolare esamina le questioni relative all'interpretazione dei sogni e descrive il rapporto tra sonno e sogni in termini naturalistici, con forti accenti materialistici. Le immagini oniriche sono anche associate ai fenomeni della memoria e dell'oblio, considerate in relazione all'immaginazione e alle influenze astrali, ben codificate nelle dottrine astrologiche antiche e moderne
Multi-code multi-carrier CDMA modulation with adaptive bit-loading for VDSL modems
No full textThis paper presents a new modulation scheme for Very-High Speed Digital Subscriber Lines (VDSL) modem, featuring a Multi-Code Multi-Carrier Code Division Multiple Access (MC2-CDMA) modulation. The system takes advantage from both the CDMA modulation and the Multi-Carrier transmission, and furthermore the channel throughput is increased adopting a multi-code approach. Starting from an overview of this novel scheme, encompassing the transmitter, channel and receiver description, a brief review of the equalization techniques is also considered and a proper bit-loading algorithm is derived to find out the achievable overall channel rate. The aim of this paper, besides introducing this novel scheme, is to demonstrate its suitability for a VDSL environment, where the achievable channel rate represents a real challenge. By means of a further optimisation, a general improvement of the system performance with respect to the standardized Discrete Multi Tone (DMT) modulation is also demonstrated
Wear Evaluation of Prosthetic Materials Opposing Themselves
No full textSUMMARY
The purpose of the present in vitro study was to compare the two-body wear resistance of a type 3 gold alloy (Aurocast8), two lithium disilicate glass ceramics (IPS e.max CAD and IPS e.max Press), a heat-pressed feldspathic porcelain (Cerabien ZR Press), an yttria-stabilized tetragonal zirconia polycrystal ceramic (Katana Zirconia ML), and three heat-cured composite resins (Ceram.X Universal, Enamel Plus Function, and Enamel Plus HRi) opposing antagonistic cusps made out of the same restorative materials. Ten 6-mm-thick samples and 10 cusp-shaped abraders were manufactured with each test material (n=10) according to standard laboratory procedures. All sample/antagonist pairs made out of the same material were subjected to a two-body wear test in a dual-axis chewing simulator for up to 120,000 loading cycles. The total vertical wear (mm) and the total volumetric loss (mm3) for each sample/antagonist pair were calculated. Data were statistically analyzed using one-way analysis of variance tests. The total vertical wear for the gold alloy was not significantly different compared to Ceram.X Universal, Enamel Plus Function, IPS e.max CAD, and Cerabien ZR Press. Significantly increased wear values were observed for Enamel Plus HRi and IPS e.max Press. The lowest values for total vertical wear and volumetric loss were recorded on the monolithic zirconia.</jats:p

Ventrites III and IV with posterior retraction not sinuate and reaching the middle of the segment. Remarks. Anchylorhynchus vanini is very similar to Anchylorhynchus aegrotus and both can be easily distinguished from most other species of Anchylorhynchus by the elytra covered by yellowish to brown scales and variably reduced scales on head and pronotum revealing the punctures (Figures 17 C–D, 7C). The shape of the pronotum, very wide in males and with a distinct inflexion in females, is also shared between A. aegrotus and A. vanini (Figures 8A, 8W). Males of A. vanini have a wider and less well-delimited metasternal concavity (Figure 17C) than males of A. aegrotus (Figure 17B). Females (Figure 13G) can be distinguished from A. aegrotus (Figure 10B) by the dark area on the pronotum. Finally, A. vanini is the only species of Anchylorhynchus with two long setae on the mandibles (Figure 4H). Most species have only one long external seta, while A. tricarinatus has three setae. Geographical Distribution. This species is known only from the state of Pará, Brazil (Figure 24), but its host plant is more widespread in transition zones between Amazonia and Cerrado. Host Plants.

Successful surgical repair of double outlet right ventricle with situs inversus, l-loop, l-malposition and subaortic VSD in a 16-month-old patient
No full textThe case of a 16-mth-old patient who had double outlet right ventricle, l-loop and l-malposition in the presence of dextrocardia and situs inversus is presented. A successful repair was performed using an internal conduit to divert the blood from the left ventricle to the aorta. The outflow tract of the right ventricle was then enlarged with a dacron patch. The anatomic variations of double outlet right ventricle surgically corrected are reviewed
