Based on an arithmetical and autocatalytic approach, the authors propose a solution for the occurrence of prime numbers. Exact arithmetical calculations are provided for: the closest prime to any given positive integer ...

The use of wood residues in polymeric matrices is notable for promoting significant mechanical reinforcement of the matrix. Such composites are widely used in the development of new composite materials with tunable mechanical ...

SiC fiber-reinforced SiC matrix composite (SiCf/SiC) is one of the leading candidates in ceramic materials for engineering applications due to its unique combination of properties such as high thermal conductivity, high ...

Objectives. This study evaluated the effect of composite pre-polymerization temperature and energy density on the marginal adaptation (MA), degree of conversion (DC), flexural strength (FS), and polymer cross-linking (PCL) ...

Compositional data consist of known vectors such as compositions whose components are positive and defined in the interval (0,1) representing proportions or fractions of a "whole", where the sum of these components must ...

This study evaluated the spin concentration and the crystallinity in different classifications of dental composites as a function of the material condition (new, aged and expired). Specimens were obtained according to the ...

This work aimed to analyze the influence of voids content, morphology (size and shape), and position on the creep behavior of glass/epoxy composites with a reduced number of experiments, applying the design of experiments ...
