Residual Stress Measurements from Surface Wave Velocity Dispersion

I'm going to try to keep you awake and I hope to tie some of the subjects that were discussed earlier today in with this paper. You may be asking, "What do I mean by velocity dispersion?" and even more, "What do I mean by residual stress?"</p

Late Jurassic crinoids from the Eperkés-hegy (Bakony Mts., Hungary)

This preliminary paper gives the first account on the systematics composition of the Late Jurassic crinoid faunas from the Bakony Mountains. Nine species are described in detail, one of them, Gammarocrinites baconicus sp.n. is new. The samples also indicate the presence of several additional species

Fungal inoculum properties : Extracellular enzyme expression and pentachlorophenol removal by New Zealand Trametes species in contaminated field soils

This study was conducted to improve the ability of indigenous New Zealand white-rot fungi to remove pentachlorophenol (PCP) from contaminated field soil. The effects of different bioaugmentation conditions on PCP removal and extracellular enzyme expression were measured in the laboratory. The conditions were fungal growth substrate and co-substrate composition, culture age, and Tween 80 addition to the contaminated soil. The fungi used were Trametes versicolor isolate HR131 and Trametes sp. isolate HR577. Maximum PCP removal was 70% after 7 wk from a 1043 mg kg⁻¹ PCP-contaminated soil inoculated with an 11-d-old fungal culture of T. versicolor isolate HR131. There was minimal production of undesirable pentachloroanisole by the fungi. Tween 80 addition had no affect on PCP removal. Poplar sawdust was more suitable as a fungal growth substrate and a co-substrate amendment for PCP removal and extracellular enzyme expression than the locally available pine and fir sawdust. Pentachlorophenol removal was not necessarily correlated with extracellular enzyme expression. The research results demonstrate that PCP biodegradation was affected by inoculum culture age, by the presence of a co-substrate amendment, and by growth substrate composition after white-rot fungal bioaugmentation into PCP-contaminated field soils
