Some observations on the biology of two rarely seen deep-sea chimaerids, Chimaera carophila and Hydrolagus homonycteris

Autor: B, Finucci, D W, Stevens, E G, Jones, M R, Dunn

Publikováno v: Journal of fish biology. 90(5)

Chimaera carophila (n = 45) and Hydrolagus homonycteris (n = 11), two deep-sea chimaerids rarely caught in the waters off New Zealand, were collected from research trawl catches and commercial fishery catches around New Zealand at depths between 400

Diets of deepwater oreos (Oreosomatidae) and orange roughy Hoplostethus atlanticus

Autor: J S, Forman, P L, Horn, D W, Stevens

Publikováno v: Journal of fish biology. 88(6)

The diets of black oreo Allocyttus niger, smooth oreo Pseudocyttus maculatus, spiky oreo Neocyttus rhomboidalis and orange roughy Hoplostethus atlanticus were determined from examination of contents of 240, 311, 76 and 415 non-empty stomachs, from fi

TEES BARRAGE. PART 3. DESIGN OF THE BRIDGE

Autor: N. A. Carstairs, D. W. Stevens, E. Carter

Publikováno v: Proceedings of the Institution of Civil Engineers - Municipal Engineer. 109:168-176

This paper describes how the design for the tubular steel arch bridge which crosses the River Tees Barrage has been developed from the original architectural concept. Decisions made during the design process are discussed, and insights into the unusu

Laser Peening of Alloy 22 Welds

Autor: D W Stevens, L A Hackel, A C Lingenfelter

Stress corrosion cracking (SCC) of near-surface Alloy 22 metal can be propagated by yield-point levels (45 ksi) of residual weld tensile stresses. This is a serious concern for welds in the Alloy 22 canister employed in the Yucca Mountain Project (YM

Age and growth of two endemic flatfish (Colistium guntheri and C. nudipinnis) in central New Zealand waters

Autor: D. W. Stevens, R. W. Hickman, R. P. McPhee, P. C. Shearer, M. J. Tait, Malcolm P. Francis

Publikováno v: Marine and Freshwater Research. 56:143

Brill (Colistium guntheri) and turbot (C. nudipinnis) were aged by counting opaque growth zones in whole and sectioned otoliths. Zones counts from whole otoliths under-estimated age compared with counts from thin otolith sections. Other species of fl

Thermal Conductivity of Beds of Coated Fuel Particles

Autor: D. W. Stevens

Publikováno v: Nuclear Applications. 3:626-634

The thermal conductivity of loose, pyrolytic carbon-coated fuel particles in helium was studied at temperatures from 1800 to 2700°F using a convenient comparative technique. The conductivities of c...

A Model for Thermal and Radiation Stress and Strain in Viscoelastic, Orthotropic Cylinders, and Its Application to Borated-Graphite Absorbers

Autor: O. M. Stansfield, D. W. Stevens

Publikováno v: Nuclear Science and Engineering. 45:73-85

An analysis has been conducted to determine stresses and displacements near the center of long viscoelastic cylinders. Stresses arise due to thermal expansion and irradiation-induced dimensional ch...

An Explicit Solution for Stresses in Pyrocarbon-Coated Fuel Particles

Autor: D. W. Stevens

Publikováno v: Nuclear Technology. 10:301-306

An explicit solution for stresses and strains in pyrolytic-carbon coatings on spherical fuel particles is presented. The resulting model is a modification of the Prados-Scott model which accounts f...
