Viscosity and Density Measurements
2. Working Equations of the Vibrating-Wire Instrument Our implementation [1] of the steady-state vibrating-wire technique is similar to that described by Audonnet and Pádua [2] in which the wire is driven at frequency f by a constant sinusoidal current I, and the emf V(f) generated across the vibrating wire is measured with a two-phase lock-in amplifier. This measured emf generally comprises tw...
متن کاملMeasuring the Density and Viscosity of Carbonated Aqueous 35 wt% Methyldiethanolamine Solution
The density and viscosity of carbonated aqueous 35wt% methyldiethanolamine solution were experimentally measured accompanied with the solubility of CO2 at temperatures from (303.15 to 363.15) K and pressures up to 0.8 MPa using the new setup developed in our laboratory.It was observed that both density and viscosity of mixtures decrease by increasing temperature and incr...
متن کاملAmalgams and χ-Boundedness
A class of graphs is hereditary if it is closed under isomorphism and induced subgraphs. A class G of graphs is χ-bounded if there exists a function f : N → N such that for all graphs G ∈ G, and all induced subgraphs H of G, we have that χ(H) ≤ f(ω(H)). We prove that proper homogeneous sets, clique-cutsets, and amalgams together preserve χ-boundedness. More precisely, we show that if G and G∗ a...
متن کاملAMALGAMS OF L ' AND l
(i.i) ll/IU=( t \ n » — oo makes (L9 l ) into a Banach space. The idea of considering the amalgam (L, l\ as opposed to the Lebesgue space L = (L,l), is a natural one because it allows us to separate the global behavior from the local behavior of a function. This idea goes back to 1926 and Norbert Wiener who considered the special cases (L,1) and (L, l°°) in [Wl] and (L°°, I) and (L\ l°°) in [W2...
متن کاملBiocompatibility of Dental Amalgams
Objective. The purpose of this review paper is to review the literature regarding the toxicology of mercury from dental amalgam and evaluate current statements on dental amalgam. Materials and Methods. Two key-words "dental amalgam" and "toxicity" were used to search publications on dental amalgam biocompatibility published in peer-reviewed journals written in English. Manual search was also co...
