The central spine or rib is narrow at the tip and broadens along the length of the arrowhead.
Two sub-triangular blades expand from either side of the spine; these are relatively narrow. The rib is a similar width on both sides of the object. A cast iron 'bodkin' arrowhead of medieval date (c. The arrowhead is formed of a triangular shaped blade which tapers to a point, and emerges from a cylindrical shaft.
The complementary nature of these spectroscopic techniques have made it possible to evaluate the state of conservation, to establish measures to clean the existing efflorescence according to their nature and to suggest dating of the materials.
Contrary to what might be expected, though, this book is not about the prehistory of this debate.
Should I trust she just hasn't updated it in a long time, or should I say something?
With this sort of red flag, keep your internal affection for her distant, but don't show any outward distrust. " I'm going to respond with a resounding "yes." You need to bridge the gap — spend time watching both sets of your programs together and addressing both the positive and negative qualities in them.
This paper reports an analytical study of enamel on fragments of medieval tiles using atomic spectroscopy techniques — AAS, XRF and SEM/EDX.
The analyses presented in this paper have been mainly performed as a preliminary check of the Cryo2Soni C methodology in order to assess its applicability to this study site by comparing observed mortar results with archaeological expectations about the citadel development phasing and charcoals found encased in mortars.A study of the soluble salts in the biscuits and mortar was carried out using AAS to determine their present capacity to produce efflorescence and the type of efflorescence.
