We reviewed the historic and present distribution of Greater Sage-Grouse (Centrocercus urophasianus) in Canada and found that the species has been eliminated from approximately 90% of its estimated historic distribution. Sage-grouse have been extirpated from British Columbia and reduced to remnant populations in Alberta and Saskatchewan. Estimates of the size of the population decline in Canada...

Low resistivity in argillaceous sandstone reservoirs may be attributed either to the effect of microporosity, or to specific effects due to clays and/or to conducting minerals. In the frame of a study on pore lining chlorite bearing sandstones, from different hydrocarbon reservoirs, measurements of cation exchange capacities and specific surface areas have been performed, on whole rocks as well...

Objective of the study is to screen for in vitro pharmacological activities of 5-Lipoxygenase and cytotoxicity of using methanolic callus extracts of Biophytum sensitivum. In vitro Brine shrimp lethality assay was carried out according to the method of Meyer et al., (1982) and the lipoxygenase inhibition activity was assayed using photometric method as described by Reddanna et al., (1985). The ...

The anesthetic management of plastic surgical procedures in the pediatric population is often challenging because of the variety of congenital syndromes that require cosmetic repair.These syndromes are associated with altered airway anatomy, as well as complex coexisting medical conditions.This chapter reviews anesthetic management of the more commonly performed plastic surgery procedures – cle...

Since entering the linguistic stage in the late sixties, Davidsonian event semantics has taken on an important role in linguistic theorizing. Davidson’s (1967) central claim is that events are spatiotemporal things, i.e., concrete particulars with a location in space and time. This enrichment of the underlying ontology has proven to be of great benefit in explaining numerous combinatorial and i...

ITE JOURNAL / FEBRUARY 2002 TOLL FACILITIES CANNOT BE CLASsified under the same pretenses as normal freeway segments or signalized intersections because of the unique characteristics associated with toll plazas being integrated within the system. Therefore, it is difficult to examine the operational conditions and accurately report the benefits of toll facilities to the public in terms they can...

Many problems from mathematics and engineering can be described in terms of reconstruction from geometric information. Reconstruction is the algorithmic problem of combining the results of measurements of some aspect of a physical or mathematical object to obtain desired information about the object. In this chapter, we consider three different classes of geometric reconstruction problems. In S...
