The use of lubricants during restorative procedures is a clinically common practice to alleviate the stickiness resin-based composite (RBCs) materials and improve its handling. This study evaluated effects three modeling liquids (ML) one universal adhesive (UA) used as layering on color stability translucency RBCs. Methods. following were applied between every 1 mm RBC layer (total restoration ...

We analyze the stability of monetary regimes in an economy where fiat money is endogenously created by the government, information about its value is imperfect, and learning is decentralized. We show that monetary stability depends crucially on the speed of information transmission in the economy. Our model generates a dynamic on the acceptability of fiat money that resembles historical account...

A research was conducted to study the perceptibility of color difference of color pairs, caused by OBA differences in paper substrates, and its relationship with quantitative measurement metrics. Based on the psychometric experiments conducted, the results show the utilization of the visual difference index (VDI), from 0 (no difference) to 3 (noticeable difference), to rate 27 color pairs with ...

New Neoclassical Synthesis models equate the instrument of monetary policy to the implied CCAPM rate arising from a standard model with power utility. This paper identifies monetary policy shocks using a multi country dataset and examines the movement of money market and implied CCAPM rates. We find that an increase in the nominal interest rate leads to a fall in the implied CCAPM rate. Incorpo...

This study proposes a feasible method for spectral color reproduction based on a node address array selection technique from CIE tristimulus values. In this method three-dimensional lookup table (3-D LUT) has been constructed to connect the node address array and the spectrum as the source and destination spaces. First we present a general framework for how to reproduce spectral color. Then res...

(identical representation). The even part G0 is characterized by the condition a0i = ai0 = 0 for i = 1, . . . , n. G0 is isomorphic to gl(n). We choose the Cartan subalgebra H as the set of diagonal matrices of G and G0 resp. Let eij be denote the (n+ 1)× (n+ 1)-matrix with 1 at the place (i, j) and 0 everywhere (i, j = 0, . . . , n) . Then we get by h1 = e00 + e11 , hi = ei−1,i−1 − eii (i = 2,...

This in vitro study aimed to evaluate surface microhardness, roughness, color, gloss and topography of low-cost Brazilian resin composites, compared with an international one. All 120 samples (8mm ø x 2mm height) were prepared divided into 5 groups: Ultrafill (Biodinâmica), Llis (FGM), Fill Magic (Coltene), Applic (Makira), Filtek Z250XT (3M Oral Care). Surface microhardness (KHN) (n=10) was an...

Objective: This study aimed to evaluate the color change of CAD/CAM resin matrix ceramic, which was exposed three different whitening mouth rinses and artificial saliva for 12 180 hours. Material Methods: A total 60 samples were produced from prefabricated ceramic blocks experimental study. The randomly divided into four subgroups according mouthrinses: Listerine Advanced White, Colgate Optic O...

Models of macroeconomic learning are populated by agents who possess a great deal of knowledge of the “true” structure of the economy, and yet ignore the impact of their own learning on that structure; they may learn about an equilibrium, but they do not learn within it. An alternative learning model is presented where agents’ decisions are informed by hypotheses they hold regarding the economy...

Indeterminacy in an economic growth model arises whenever the stable manifold has dimension greater than the number of predetermined initial conditions. The stability (indeterminacy) of transition paths in the Benhabib and Farmer (1996) model of growth is investigated, using both the Lyapunov method and numerical simulation techniques. The sensitivity of transient dynamics is analyzed with resp...
