Geneviève Duggan and Hans Hägerdal, Savu: History and Oral Tradition on an Island of Indonesia. Singapore: NUS Press. 2018, 720 p. ISBN: 978-981-4722-75-9.

This lengthy, well-produced, and richly illustrated book concerns the small, geographically remote, ethno-linguistically homogeneous, and relatively impoverished island of Savu, located in eastern Indonesia between the islands of Timor and Sumba. This in itself is a distinctive feature, especially nowadays when such comprehensive works on small-scale non-Western societies are a rarity. But the volume is positively unusual in other respects as well. It is co-written by an anthropologist and a ..

Damage Tolerance Analysis of a Pressurized Liquid Oxygen Tank

A damage tolerance assessment was conducted of an 8,000 gallon pressurized Liquid Oxygen (LOX) tank. The LOX tank is constructed of a stainless steel pressure vessel enclosed by a thermal-insulating vacuum jacket. The vessel is pressurized to 2,250 psi with gaseous nitrogen resulting in both thermal and pressure stresses on the tank wall. Finite element analyses were performed on the tank to characterize the stresses from operation. Engineering material data was found from both the construction of the tank and the technical literature. An initial damage state was assumed based on records of a nondestructive inspection performed on the tank. The damage tolerance analyses were conducted using the NASGRO computer code. This paper contains the assumptions, and justifications, made for the input parameters to the damage tolerance analyses and the results of the damage tolerance analyses with a discussion on the operational safety of the LOX tank
