The aluminum bronze matrix alumina composites using hot press and resin infiltration were investigated to study their porosities, hardness, bending strengths, and microstructures. The experiment results show that the hardness of the sintered composites with the decrease of porosity increases. The composites without and with resin infiltration have about HRF 42-61 of about 34-40% of porosity and...
N The Terracotta Army that protected the tomb of the Chinese emperor Qin Shihuang offers an evocative image of the power and organisation of the Qin armies who unified China through conquest in the third century BC. It also provides evidence for the craft production and administrative control that underpinned the Qin state. Bronze trigger mechanisms are all that remain of crossbows that once eq...
A. Eksi, Faculty of Engineering and Architecture, Çukurova University, Adana, Turkey, M. K. Kulekci, Faculty of Technical Education, Mersin University, Tarsus, Turkey In this study hardness and densification behaviour of copper and bronze powders under wet bag cold isostatic and uniaxial die pressing processes are examined. In uniaxial pressing the specimens were compacted up to a pressure of 8...
We analyse new genomic data (0.05-2.95x) from 14 ancient individuals from Portugal distributed from the Middle Neolithic (4200-3500 BC) to the Middle Bronze Age (1740-1430 BC) and impute genomewide diploid genotypes in these together with published ancient Eurasians. While discontinuity is evident in the transition to agriculture across the region, sensitive haplotype-based analyses suggest a s...
Compound specific stable isotope analyses of managed soils using isotope ratio mass spectrometry have been undertaken as a means of determining early land use practices. delta (15)N amino acid signals demonstrate differences between manured grassland, unmanured grassland and continuous cereal cultivation under long-term experimental land use control conditions, with delta (15)N in hydrophobic a...
Blade of a small bronze knife of the type used by Egyptian scribes of the New Kingdom for trimming their brushes, cutting sheets of papyrus, and the like. It was once the property of the Chief Steward Thot-hotpe, who served Het-shepswet during her reign as "king" of Egypt (1497-1482 B.C.), and is inscribed with the title and name of this important official. The blade, minus its curved handle, w...

The goal of this paper is to make an architecture framework for wireless sensor networks that is used for water management application. The proposed framework focuses on offering differentiated services for sensor nodes. Differentiated services are supported based on the information passed from the sensor node to differentiated service motes. Three differentiated services are offered gold, silv...
Purpose: To introduce a new myofascial release method named “roptrotherapy” that consists of deep cross-friction massage with the aid of a myofascial T bar (roptron). Description: The intervention of roptrotherapy consists of a 30-minute session, total, of deep-friction massage with the aid of a myofascial T bar. These bars are made of bronze, a neutral material to skin. The advantages of bronz...
