Abstract:

A quantitative description of overlaps on fractures in sialon ceramics, is presented in the paper. A conventional analysis, aiming at the determination of the percentage share of overlaps on the basis of quantitative fractography, was preceded by stereometric/fractal analyses. They enabled the selection of representative sections of samples and then, the production of transverse microsections in those places for an analysis of the fractures’ profiles using the light microscopy method and fractographic image analysis. Based on the compared results from both methods, a successful verification wa

Abstract:

Analysis of issues related to the cracking process of materials requires a quantitative description of the problem which frequently, due to its complexity, is difficult or impossible to solve. In a number of cases, the deficiencies of a quantitative description made using classical methods are compensated for by such unconventional tools as percolation, which requires creating an appropriate model. The aim of the study was to use a three-dimensional minimal spanning tree (3DMST) to create a model of the crack path, based on an example of a metallic biomaterial. For this purpose, a stereometric

Abstract:

Micro ball grid array (BGA) technology has gained attention due to the increasing density and miniaturization of BGA packages. Underfill is applied to BGA components to protect solder joints from mechanical and thermal stress, and reducing the risk of solder joint failure during thermal cycling test (TCT). Numerous studies have explored underfill materials, processing, and dispensing patterns in BGA components, but less focus on quantitative impact of underfills towards solder joint damage. This study employs stereometric analysis to quantify underfillinduced damage on micro-BGA solder joints

Abstract:

The variety of mitochondrial morphology in healthy and diseased cells can be explained by regulated mitochondrial fusion. Previously, a mitochondrial outer membrane fraction containing fusogenic, aluminum fluoride (AlF4)-sensitive GTP-binding proteins (mtg) was separated from rat liver (J. D. Cortese, Exp. Cell Res. 240: 122–133, 1998). Quantitative confocal microscopy now reveals that mtg transiently increases mitochondrial membrane potential (ΔΨ) when added to permeabilized rat hepatocytes (15%), rat fibroblasts (19%), and rabbit myocytes (10%). This large mtg-induced ΔΨ increment is blocked

Designing a new generation of biomaterials is based on the assumption that the appropriate chemical composition of a material, the chemical state of its surface and the surface structure in nanoand micrometer scales are the elements which selected in a planned way decide on the type of cellular response to the material. The use of quantitative fractography enables a quantitative description of the surface. The parameter most frequently used in surface stereometry is the area development coefficient Sdr.

Abstract:

Resistance to brittle cracking is one of the most important functional properties of sialon ceramics. Evaluation of the resistance requires an analysis of decohesion processes occuring in the material. Aiming at a comprehensive description of the morphology of typically brittle fractures, a quantitative characterization was made using different methods and techniques, regarding the surface of fractures formed in a three-point bending test. By using the parameter Sdr, determined via the surface stereometry method, the fracture surface development coefficient, RS, typical for fractography, was c

Morphometry is one of the most important methods of preclinical studies. It is an integral part of microscopy analysis. The main problems of microscopic analysis are variability of microscopic findings, absence of uniformity of the terms and definitions, the subjectivity of the pathologist’s perception. Thus, the traditional histopathologic description does not can use for a full and objective assessment of experimental disease.
