Question: In which country was a large metal hammer-head excavated? Passage 1:While in London performing at The Rainbow Theatre, Dingwall's, and trendy Cabaret Futura, the Bongos recorded their early singles and their well-received debut EP Time and the River for UK-based Fetish Records. Cover designs for their Fetish releases were created by influential graphic artist Neville Brody, who was soon to become the designer of The Face magazine. The group's love of avant-garde performers brought them in touch with artists such as Throbbing Gristle and Clock DVA who performed with them live in London, and on their recordings. Their debut U.S. album, Drums Along the Hudson, compiled from the band's British singles, was released in 1982 to widely favorable reviews on both sides of the Atlantic. While Trouser Press suggested that the group "may trade a certain amount of substance for easy appeal," it added that "there's no better musical equivalent of whipped cream anywhere." Writing in the Village Voice, Robert Christgau dryly commented that "for all their jumpy originality [the songs are] still slight, and Richard Barone's lyrics are so oblique you have to wonder what his angle is." In 2007 however, Jim DeRegotis wrote in the Chicago Sun-Times: "The initial impression of naiveté is offset by deceptively simple lyrics that actually hint at deep, dark mysteries and unfathomed mystical enigmas." The group's cover of T. Rex's "Mambo Sun" reached No. 22 on the Billboard Dance Chart. A thriving Hoboken pop scene emerged, triggered by the Bongos and Maxwell's, which gained national media attention, and drew many bands and fans to the city. An August 1, 1982 article in the New York Times Real Estate section hinted at the scene's popularity as an influence on increasing rents and property values.
 Passage 2:The main components for water-powered stamp mills – water wheels, cams, and hammers – were known in the Hellenistic era in the Eastern Mediterranean region. Ancient cams are in evidence in early water-powered automata from the third century BC. A passage in the Natural History of the Roman scholar Pliny (NH 18.23) indicates that water-driven pestles had become fairly widespread in Italy by the first century AD: "The greater part of Italy uses an unshod pestle and also wheels which water turns as it flows past, and a trip-hammer [mola]". These trip-hammers were used for the pounding and hulling of grain. Grain-pounders with pestles, as well as ordinary watermills, are also attested as late as the middle of the fifth century in a monastery founded by Romanus of Condat in the remote Jura region, indicating that the knowledge of trip hammers continued into the early Middle Ages. Apart from agricultural processing, archaeological evidence also strongly suggests the existence of trip hammers in Roman metal working. In Ickham in Kent, a large metal hammer-head with mechanical deformations was excavated in an area where several Roman water-mills and metal waste dumps have also been traced.
 Passage 3:Kalpathy Easwaran, born on 7 July 1939 in the South Indian state of Kerala in a brahmin family, graduated in science from Government Victoria College, Palakkad and secured his master's degree (MSc) from the University of Mumbai in 1962 to pursue his doctoral studies at the department of physics of the Indian Institute of Science, which he obtained in 1967. His post-doctoral research was at Tata Institute of Fundamental Research during 1966–67 and later at the University of Washington after which he spent a year at Jožef Stefan Institute as a visiting scientist. Returning to India in 1970, he resumed his career at the Indian Institute of Science, holding such positions as Astra Chair professorship (1994–97), Chair of the department of molecular biophysics (until 2006) and as Indian National Science Academy Senior Scientist (2006–07) until his superannuation in 2007. In between, he served as a visiting faculty at institutions such as Harvard Medical School, University of Connecticut, Georgetown University, United States Naval Research Laboratory and National University of Singapore. Post retirement, he is involved with ABL Biotechnologies, a Chennai-based biotechnology institution.
