Effect on the Compressive and Diametral Tensile Strength of Type II GIC reinforced with Nanohydroxyapatite Derived from “Anadara granosa”: An In Vitro Study [PDF]

International Journal of Prosthodontics and Restorative Dentistry, 2023
Purpose: Glass ionomer cement (GIC) is a commonly used restorative material. However, it lacks sufficient strength and wear resistance to be used as a posterior restorative material. The purpose of this study was to evaluate the compressive and diametral

Diametral dimensions of Fréchet spaces [PDF]

Studia Mathematica, 2016
The diametral dimension is an important topological invariant in the category of Frechet spaces which has been used, e.g., to distinguish types of Stein manifolds. We introduce variants of the classical definition in order to solve an old conjecture of Bessaga, Mityagin, Pelczynski, and Rolewicz at least for nuclear Frechet spaces. Moreover, we clarify

Diametral dimension of some pseudoconvex multiscale spaces [PDF]

Studia Mathematica, 2010
Stemming from the study of signals via wavelet coefficients, the spaces S(nu) are complete metrizable and separable topological vector spaces, parametrized by a function nu, whose elements are sequences indexed by a binary tree. Several papers were devoted to their basic topology; recently it was also shown that depending on nu, S(nu) may be locally ...

Some Remarks on Diametral Dimension and Approximate Diametral Dimension of Certain Nuclear Fréchet Spaces [PDF]

Bulletin of the Belgian Mathematical Society - Simon Stevin, 2020
The diametral dimension, $ (E)$, and the approximate diametral dimension, $ (E)$, of a nuclear Fr chet space $E$ which satisfies $\underline{DN}$ and $ $, is related to power series spaces $ _{1}(\varepsilon)$ and $ _{\infty}\left(\varepsilon\right)$ for some exponent sequence $\varepsilon$. In this article, we examine a question of whether $ (E)

Using small-angle X-ray scattering to investigate the compaction behaviour of a granulated clay [PDF]

, 2015
The compaction behaviour of a commercial granulated clay (magnesium aluminium smectite, gMgSm) was investigated using macroscopic pressure-density measurements, X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray microtomography (XμT) and ...

On the equality between two diametral dimensions

Functiones et Approximatio Commentarii Mathematici, 2017
Let \(E\) be a locally convex space. The diametral dimension of \(E\) is the set \[ \Delta(E)=\{\xi\in\mathbb C^{\mathbb N_0}: \forall V\in \mathcal{V}(E)\;\exists U\in \mathcal{V}(E)\;\text{such\;that}\;U\subset V \;\text{and }\;(\xi_n \delta_n(U,V))_{n\in\mathbb N_0}\in c_0 \}, \] where \(\mathcal{V}(E)\) is a basis of \(0\)-neighbourhoods in \(E ...

On the micro mechanics of one-dimensional normal compression [PDF]

, 2015
Discrete-element modelling has been used to investigate the micro mechanics of one-dimensional compression. One-dimensional compression is modelled in three dimensions using an oedometer and a large number of particles, and without the use of ...

Strictly singular operators and isomorphisms of Cartesian products of power series spaces [PDF]

, 1998
V. P. Zahariuta, in 1973, used the theory of Fredholm operators to develop a method to classify Cartesian products of locally convex spaces. In this work we modify his method to study the isomorphic classification of Cartesian products of the kind E0p(a)×
