Birds of India (Collins Field Guide)
This comprehensive new field guide is an excellent addition to the world-renowned series – the ultimate reference book for travelling birdwatchers.
Constructing the Field
Ethnographic fieldwork is traditionally seen as what distinguishes social and cultural anthropology from the other social sciences. This collection responds to the inte nsifying scrutiny of fieldwork in recent years. It challenges the idea of the necessity for the total immersion of the ethnographer in the field, and for the clear separation of professional and personal areas of activity. The very existence of 'the field' as an entity separate from everyday life is questioned. Fresh perspectives on contemporary fieldwork are provided by diverse case-studies from across North America and Europe. These contributions give a thorough appraisal of what fieldwork is and should be, and an extra dimension is added through fascinating accounts of the personal experiences of anthropologists in the field.
Naples '44
Norman Lewis arrives in war-torn Naples as an intelligence officer in 1944. The starving population has devoured all the tropical fish in the aquarium, respectable women have been driven to prostitution and the black market is king. Lewis finds little to admire in his fellow soldiers, but gains sustenance from the extraordinary vivacity of the Italians. There is the lawyer who earns his living bringing a touch of Roman class to funerals, the gynaecologist who "specializes in the restoration of lost virginity" and the widowed housewife who times her British lover against the clock. "Were I given the chance to be born again," writes Lewis, "Italy would be the country of my choice."

Surface Integrity of Machined Structural Components
A program has been run to evaluate the effects of different metal removal methods and variations of these methods on surface integrity. Three alloys were studied: beta rolled Ti-6Al-4V; AISI 4340, quenched and tempered, 50 Rc; and Inconel 718, solution treated and aged. Various grinding procedures caused the titanium alloy to exhibit a fatigue strength range of 13 to 62 ksi. The fatigue strength of 4340 due to grinding variables ranged from 62 to 102 ksi, while Inconel 718 showed a range of 24 to 60 ksi. Abusive grinding conditions always resulted in fatigue strengths at the minimum of these ranges. Milling variables exhibited a fatigue strength range of 32 to 72 ksi in the beta rolled titanium alloy. EDM and ECM on Inconel 718 yielded 22 and 39 ksi, respectively, compared to 60 ksi for gentle grinding. Guidelines for processing aerospace hardware considering surface integrity requirements are presented in the report.
