Evaluation of macrostructural bone biomechanics
Joint Bone Spine, 2007Bone fragility can be defined as an increased risk of fractures. Advanced age and bone diseases such as osteoporosis increase the fracture risk. Understanding the effects of osteoporosis and its treatments requires a description of the mechanical behavior of bone tissue.

Abstract This chapter describes several macroscopic examination techniques, including macroetching, contact printing, fracturing, and lead exudation. It explains how each method is implemented, why it is used, and what it reveals about manufacturing processes, defects, imperfections, and failure mechanisms.

The exterior morphology of meteorites recovered soon after fall is generally characterized by flight markings. Meteorites which have maintained a constant orientation during their fall have furrows on their forward surfaces radiating away from the apex. The rear surface is either unmarked or is furrowed, with the wavelength longer and amplitude smaller

Macrostructure of geomagnetic bays
Journal of Geophysical Research, 1968Evidence is presented that suggests that geomagnetic bay disturbances occur in two stages. The onset of each stage is accompanied by a Pi 2 micropulsation; the fact that a Pi 2 occurs almost synchronously over the earth's surface allows the onset of this micropulsation to be used to define the onset of each stage of a bay.

Etchants for Revealing Macrostructure
1984Abstract This appendix provides a list of etch compositions and procedures that reveal the macrostructure of aluminum, beryllium, bismuth, antimony, cobalt, copper, lead, magnesium, nickel, tin, titanium, zinc, and their respective alloys as well as iron, steel, noble metals, refractory metals, silicon, zirconium, and hafnium.
