Observations on the larval hatching success of dungeness crab, Cancer magister, from the San Francisco and Eureka-Crescent City region
Ovigerous Dungeness crabs were collected from the San
Francisco and Eureka-Crescent City regions and maintained at
the Department's Marine Culture Laboratory near Monterey.
Hatching success, expressed as viable larvae released, was
measured and compared by region. Larval counts were made from 15 Dungeness crabs, 5 from the San Francisco region, 7 from the Eureka-Crescent City area and 3 of unknown origin. Mean hatching success exceeded 80% in the San Francisco region, and averaged more than 90% in the Eureka-Crescent City area. However, a Student's t-Test showed this difference in hatching success was not significant. (16pp.
Study of photo-proton reactions driven by bremsstrahlung radiation of high-intensity laser generated electrons
Photo-nuclear reactions were investigated using a high power table-top laser. The laser system at the University of Jena ( I similar to 3-5 x 10(19) W cm(-2)) produced hard bremsstrahlung photons ( kT similar to 2(9 MeV) via a laser-gas interaction which served to induce ( gamma, p) and ( gamma, n) reactions in Mg, Ti, Zn and Mo isotopes. Several ( gamma, p) decay channels were identified using nuclear activation analysis to determine their integral reaction yields
In Search of a Trade Mark: Search Practices and Bureaucratic Poetics
Trade marks have been understood as quintessential ‘bureaucratic properties’. This article suggests that the making of trade marks has been historically influenced by bureaucratic practices of search and classification, which in turn were affected by the possibilities and limits of spatial organisation and technological means of access and storage. It shows how the organisation of access and retrieval did not only condition the possibility of conceiving new trade marks, but also served to delineate their intangible proprietary boundaries. Thereby they framed the very meaning of a trade mark. By advancing a historical analysis that is sensitive to shifts, both in actual materiality and in the administrative routines of trade mark law, the article highlights the legal form of trade mark as inherently social and materially shaped. We propose a historical understanding of trade mark law that regards legal practice and bureaucratic routines as being co-constitutive of the very legal object itself
