The Early Economy of Al-Fustat: Evidence from the Henri Amin Awad Collection by Jere L. Bacharach,
Corroded pieces of metal, stamped lumps of copper, broken bits of glass with partial inscriptions, fragments of textiles, tiny beads -- these were the raw material found at al-Fustat, the site of the first Muslim settlement in Egypt in the seventh century and the heart of Cairo for many centuries following. From the 1950s Dr. Henri Amin Awad accepted from the poor in this area objects that had no obvious market value in return for medical services rendered. Over the years he built up an extraordinary and important collection of artifacts. Carefully cleaned, sorted, and then analyzed by specialists, this material illuminates many areas of the archaeological record neglected or missing from other studies. The ten studies in this volume -- covering beads, bone, coins, glass weights and vessel stamps, medical instruments, medical prescriptions, metal objects, and textiles -- demonstrate the wide range of archaeological material once found in al-Fustat, a site no longer accessible since most of it has been buried under urban development or lost to a rising water table.



Process Analyzer Sample Conditioning Systems by Robert E. Sherman,
Process Analyzer Sample Conditioning Systems by Robert E. Sherman,
"Sampling systems are one part chemistry, one part engineering (electrical, chemical, mechanical, civil, and maybe even software). No one person possesses all of the knowledge required. Bob (Sherman) comes as close as anyone." John A. Crandall, V.P. Sales Americas, ABB Process Analytics This resource provides both novice and experienced technologist with the technical background necessary to choose sample conditioning system components that will allow the process analyzer system to function reliably with minimal maintenance. The conditioned process sample presented to the process analyzer should be of similar quality to the calibration material used to zero and span the analyzer. Filling a long-standing void in the process field, this book addresses the system concept of Process Analyzer Sample-Conditioning Technology in light of the critical importance of delivering a representative sample of the process stream to the process analyzer. Offering detailed descriptions of the equipment necessary to prepare process samples, and listings of two or more vendors (when available) for equipment reviewed, Process Analyzer Sample-Conditioning System Technology discusses: The importance of a "truly representative sample" Sample probes, transfer lines, coolers, and pumps Sample transfer flow calculations for sizing of lines and system components Particulate filters, gas-liquid and liquid-liquid separation devices Sample pressure measurement and control Enclosures and walk-in shelters, their electrical hazard ratings and climate control systems With extensive system and component examplesincluding what worked and what didntProcess Analyzer Sample-Conditioning System Technology givesthe new technologist a basic source of design parameters and performance-proven components as well as providing the experienced professional with a valuable reference resource to complement his or her experience.



Amine oxide - An amine oxide, also known as amine-N-oxide and N-oxide, is a chemical compound that contains the functional group R3N+-O− (sometimes written as R3N=O or R3N→O). In the strict sense the term amine oxide applies only to oxides of tertiary amines including nitrogen-containing aromatic compounds like pyridine, but is sometimes also used for the analogous derivatives of primary and secondary amines.

Quadrupole mass analyzer - The quadrupole mass analyzer is one type of mass analyzer used in mass spectrometry. In a quadrupole mass spectrometer the quadrupole mass analyzer is the component of the instrument responsible for guiding sample ions to a detector, based on their mass/charge ratio (m/z).

Aromatic amine - An aromatic amine is an amine with an aromatic substituent - that is -NH2, -NH- or nitrogen group(s) attached to an aromatic hydrocarbon, whose structure usually contains one or more benzene rings.

Bus analyzer - A bus analyzer is a computer bus analyzation tool, often a combination of hardware and software, used during development of device drivers for a specific bus and for reverse engineering of devices by reading and interpreting bus traffic. It is essentially a logic analyzer with some additional knowledge of the underlying bus traffic characteristics.
