Comparison of GTR, T-PRF and open-flap debridement in the treatment of intrabony defects with endo-perio lesions : a randomized controlled trial
2019
Background Titanium- prepared platelet rich fibrin (T-PRF) is an autologous hemo-component with a high concentration of platelets that also incorporates leukocytes, and growth factors into the dense fibrin matrix and can be used as a healing biomaterial. This study assesses the adjunctive use of T-PRF in intrabony defects (IBDs) with open flap debridement (OFD) in comparison with guided tissue regeneration (GTR) as a gold standard and OFD alone as a control. Material and Methods A total of 45 patients (15 per group) were randomized as either T-PRF (test group), GTR (test group), or OFD alone (control group) sites. Probing depth (PD), clinical attachment level (CAL), and IBD were recorded. T…
Non solo Platone. Il primato dell'oralità nel retore Alcidamante
2020
Il saggio è dedicato all’orazione Sugli autori dei discorsi scritti o sui sofisti, attribuita al retore Alcidamante, discepolo di Gorgia e attivo in Atene tra il 410 e il 365 a.C. Argomento dell’orazione è il serrato confronto tra due differenti modalità oratorie, l’autoschediazein (“parlare a braccio”) — cui Alcidamente accorda una netta superiorità — e il "gegrammena legein (“pronunciare discorsi scritti”). L’interesse di questo testo (databile con buona approssimazione intorno al 390 a. C) consiste essenzialmente nel rappresentare un punto di vista specificamente retorico sulla questione delle differenze tra scritto e parlato. Nonostante alcune significative convergenze con il ben più ce…
State and nation in African constitutionalism : thematic study
2013
Only the State had a legal personality at the end of the 1789 Revolution. Derived from the phrase "[t] he State is the legal personification of a nation", the above-mentioned personality endows the first (state), to the detriment of the second (the nation), subjective rights. What about after the democratic revolution of 1989, that is to say, some two centuries later? This study attempts to show the revanche of the nation in legal theory from a context in which it was particularly bullied. On the one hand, the nation has a double mediate and immediate representation of the fact that it participates, with an initial legislative power, the formation of the general Will. We also know that the …
Measurement of the Convective Heat-Transfer Coefficient
2014
We propose an experiment for investigating how objects cool down toward the thermal equilibrium with its surrounding through convection. We describe the time dependence of the temperature difference of the cooling object and the environment with an exponential decay function. By measuring the thermal constant tau, we determine the convective heat-transfer coefficient, which is a characteristic constant of the convection system.
Rubidium dimers in paraffin-coated cells
2010
Measurements were made to determine the density of rubidium dimer vapor in paraffin-coated cells. The number density of dimers and atoms in similar paraffin-coated and uncoated cells was measured by optical spectroscopy. Due to the relatively low melting point of paraffin, a limited temperature range of 43-80 deg C was explored, with the lower end corresponding to a dimer density of less than 10^7 cm^(-3). With one-minute integration time, a sensitivity to dimer number density of better than 10^6 cm^(-3) was achieved. No significant difference in dimer density was observed between the cells.
Fractional visco-elastic Timoshenko beam deflection via single equation
2015
SUMMARY This paper deals with the response determination of a visco-elastic Timoshenko beam under static loading condition and taking into account fractional calculus. In particular, the fractional derivative terms arise from representing constitutive behavior of the visco-elastic material. Further, taking advantages of the Mellin transform method recently developed for the solution of fractional differential equation, the problem of fractional Timoshenko beam model is assessed in time domain without invoking the Laplace-transforms as usual. Further, solution provided by the Mellin transform procedure will be compared with classical Central Difference scheme one, based on the Grunwald–Letni…
The effect of pregnancy on orthodontic tooth movement in rats
2012
Introduction: The purpose of this study was to investigate the effect of pregnancy on orthodontic tooth movement in Wistar rats. Material and Methods: Forty eight female three-month old Wistar rats with an average weight of 250 ±25 g r were selected and randomly divided into two experimental (pregnant) and control groups (non-pregnant). Maxillary central incisors were tipped distally by insertion of springs exerting 30g force. Two, seven and fourteen days after spring insertion animals were sacrificed. Then the mesioincisal distance between maxillary incisors were measured. Subsequently, histological sections were prepared to count osteoclasts under a light microscope. The data on the exten…
Combination of D0 measurements of the top quark mass
2017
We present a combination of measurements of the top quark mass by the D0 experiment in the lepton+jets and dilepton channels. We use all the data collected in Run I (1992--1996) at $\sqrt s=1.8$ TeV and Run II (2001--2011) at $\sqrt s=1.96$ TeV of the Tevatron $p \bar{p}$ collider, corresponding to integrated luminosities of 0.1 fb$^{-1}$ and 9.7 fb$^{-1}$, respectively. The combined result is: $m_t = 174.95 \pm0.40\,{\rm(stat)} \pm 0.64\,{\rm(syst)}\,{\rm{GeV}}=174.95 \pm 0.75 \, {\rm{GeV}}$.
Combined Forward-Backward Asymmetry Measurements in Top-Antitop Quark Production at the Tevatron
2018
The CDF and D0 experiments at the Fermilab Tevatron have measured the asymmetry between yields of forward- and backward-produced top and antitop quarks based on their rapidity difference and the asymmetry between their decay leptons. These measurements use the full data sets collected in proton-antiproton collisions at a center-of-mass energy of √s=1.96 TeV. We report the results of combinations of the inclusive asymmetries and their differential dependencies on relevant kinematic quantities. The combined inclusive asymmetry is At¯tFB=0.128±0.025. The combined inclusive and differential asymmetries are consistent with recent standard model predictions.
