An Introduction to Differential Geometry with Applications to Elasticity

This monograph offers the elemental theorems of differential geometry in three-d house, together with a radical insurance of floor thought. via a chain of rigorously chosen and consultant mathematical versions this monograph additionally explains at size how those theorems are utilized in third-dimensional elasticity and in shell conception. The presentation is largely selfcontained, with a very good emphasis on pedagogy. particularly, no "a priori" wisdom of differential geometry or of elasticity conception is thought, the one specifications are an inexpensive wisdom of uncomplicated research, practical research, and a few acquaintance with usual and partial differential equations.

Introduction to X-ray Powder Diffractometry, Volume 138

While bombarded with X-rays, reliable fabrics produce specific scattering styles just like fingerprints. X-ray powder diffraction is a method used to fingerprint reliable samples, that are then pointed out and cataloged for destiny use-much the way in which the FBI retains fingerprints on dossier. the present database of a few 70,000 fabric prints has been placed to a large diversity of makes use of, from the research of moon rocks to trying out medicines for purity.
