Nitrogen Fixation by Ceanothus.
The rapidity of successioni of Ceanothus species in burned-over areas where they are indigenous and the apparent enhancing effect which these species have on the development of other shrubs and ground cover suggests that Ceanothus has a soil-improvement effect and implies the fixation of nitrogen. Nodulation of some species of Ceanothus was observed as early as 1912 (3). Bottomley and also Petr...

متن کاملEstimating Building Construction Costs by Production Processes
Building actors need accurate estimates in order to efficiently undertake the construction of buildings. The knowledge of real expected costs of construction works is a necessary condition for contractors to submit competitive tenders and for developers to be aware of the magnitude of their investment. In this paper, an innovative process-based model is presented, the POP model. This model aims...
متن کاملContextual Multi-Dimensional Browse
Browsing, which usually alternates with search in information seeking on the web, highly depends on information organization of the browsed web site. An emerging web content categorization is multi-faceted, which does not impose any rigid structure, and allows users to slice and dice the information space from any chosen “dimensions” they wish to browse. However, owing to the limited capacity o...
متن کاملGeographic distribution and genetic diversity of Ceanothus-infective Frankia strains.
Little is known about Ceanothus-infective Frankia strains because no Frankia strains that can reinfect the host plants have been isolated from Ceonothus spp. Therefore, we studied the diversity of the Ceonothus-infective Frankia strains by using molecular techniques. Frankia strains inhabiting root nodules of nine Ceanothus species were characterized. The Ceanothus species used represent the ta...
