An execution of a database system is considered correct if its net effect is as if transactions were executed serially, and such an execution is called serializable. In this short paper we show that the serializability test problem can be reduced to a simple pebbling problem. Our characterization is intuitive...
In vivo spectral analysis of radish leaves sought effects on radish light harvesting apparatus (LH) of the herbicides: clomazone (FMC57020; [2-(2-chlorophenyl) methyl-4,4 dimethyl-3-isoxalidinone), diuron (DCMU; [3-(3,4-dichlorophenyl)-l,ldimethylurea)] and amitrol (H-1,2,4-triazole-3-amine). All herbicides used cause visual symptoms of chlorosis or damage chloroplast membranes and thus disrupt LH structure. The spectra were obtained...
Several new herbicides were compared with those presently being used in Oregon to control weeds in snap beans, red beets and new plantings of strawberries. The results of these tests are summarized in tabular form.
Deep-sea bamboo coral (Isidella sp.) SE000901A from the southern Oregon coast (water depth 1048m) provides a high-resolution record of variability of North Pacific Intermediate Water (NPIW) and carbon rain to the sea floor, related to coastal upwelling, from 1808 to 2000AD. Counting of annual layers in magnesium to calcium (Mg/Ca)...
Intensity beam profiles of a 633 nm laser off a super-polished glass surface were captured using surface polarization reflection. Profile capture can be difficult due to the relative intensities of molecular reflection versus macro reflection. Surface polarization reflection uses parallel polarized light incident at Brewster’s angle to extinguish macro reflection....
The impact of recent severe droughts throughout the United States, the potential for climate change to intensify the frequency and severity of drought, and discussion about the future of government assistance in agriculture highlight the need for a transition from drought as ‘disaster’ to drought as ‘managed risk’. However, guidance...
In response to the growing environmental concern and higher operating cost of regular automobile, the concept of Low-Speed Vehicles (LSVs) is becoming popular as a sustainable mode of transportation. Primarily designed for protected environments and gated communities, the use of these vehicles is gradually increasing on public roadways as a...
In the Pacific Northwest snow is an important
