Local geology controlled the feasibility of vitrifying Iron Age buildings
During European prehistory, hilltop enclosures made from polydisperse particle-and-block stone walling were exposed to temperatures sufficient to partially melt the constituent stonework, leading to the preservation of glassy walls called 'vitrified forts'. During vitrification, the granular wall rocks partially melt, sinter viscously and densify, reducing inter-particle porosity. This process ...
متن کاملMoufang Buildings and Twin Buildings
The “Moufang Condition” for spherical buildings was introduced by J. Tits in the appendix of [9], as a tool to give more structure to the classification of spherical buildings of rank at least three (which are automatically “Moufang”). More recently, also the spherical buildings of rank 2 satisfying the Moufang Condition are classified [13]. Hence one could say that, on the geometric level, sph...
متن کاملValidation of Two Portable Instruments to Measure Iron Concentration in Groundwater in Rural Bangladesh
Iron is ubiquitous in natural water sources used around the world for drinking and cooking. The health impact of chronic exposure to iron through water, which in groundwater sources can reach well above the World Health Organization's defined aesthetic limit of 0.3 mg/L, is not currently understood. To quantify the impact of consumption of iron in groundwater on nutritional status, it is import...
متن کاملSystolizing Buildings
We introduce a construction turning some Coxeter and Davis realizations of buildings into systolic complexes. Consequently groups acting geometrically on buildings of triangle types distinct from (2, 4, 4), (2, 4, 5), (2, 5, 5), and various rank 4 types are systolic.
متن کاملIntelligent Buildings
The emergence of intelligent buildings is founded on the rapid development of microcomputer and internet technology as well as the advance of information and communication technology. With the help of these technologies, office affairs have shifted from the traditional pattern of labor intense and large volume to the flexible, diverse, efficient, user-friendly, and highly reliable operations. M...
