Data on the diversity and distribution of enzyme activities in native ectomycorrhizal (ECM) communities are inadequate. A microplate multiple enzymatic test was developed which makes it possible to measure eight enzyme activities on 14 individual, excised ECM root tips. Hydrolytic and oxidative enzymes are involved in the decomposition of lignocellulose, chitin and phosphorus-containing organic...

In the Spring of 1993, the authors participated in a USC seminar course in Knowledge Based Software Engineering (KBSE) which involved the development of ten prototype KBSE applications. Evaluations of these prototype applications indicated a considerable range of relative utility to practicing software engineers. For potential discussion at the SE/ AI workshop, we offer below an analysis of som...

During the final week of testing, our system was run on test sets TST3 and TST4 . Test set TST3 contains 100 articles from the same time period as the training corpus (DEV), and test sets TST1 and TST2 . The summary of score results for TST3 is shown in Table 1 . Test set TST4 contains 100 articles from a differen t time period then those of TST3. The summary of score results for TST4 is shown ...

This report summarizes the work conducted at the USC Interaction Lab in the scope of the DARPA MARS 2020 Program project “Acquisition of Autonomous Behaviors by Robotic Assistants”, via the NASA subcontract NAG9-1444 “Skill Learning by Primitives-Based Demonstration & Imitation”. It covers the full period of the project, from August/01/2002 to August/31/2004.

A recent literature survey on natural gamma rays has yielded data on the dose rate levels above soils and rocks in the world, classified by their associated bedrock types. For comparison, the data in the Japanese Islands were also collected. The compiled results indicated a strong linear correlation between the soil and the rock dose rates. A soil-mass balance model was used to obtain the quant...

Strains arg-1T (T = type strain) and arg-2T, two new strains of extremely halophilic archaea, were isolated from the soils of the Argentine salt flats. The taxonomic features of arg-1T were similar to, but distinct from, those of the type strain of Haloarcula vallismortis and other Haloarcula species. On the 16S rRNA phylogenetic tree, strain arg-1T formed a cluster together with Haloarcula spe...
