Impact evaluation of a slush stock chest bypass installed at Scott Paper Company under the energy $avings plan
This impact evaluation of the bypass of a slush stock chest that was recently installed at Scott Paper Company (Scott Paper) was conducted for the Bonneville Power Administration (Bonneville) as part of an evaluation of its Energy P) Program. The project consists of installing an adjustable speed drive, a 74.6 kW (100 hp) pump, a re-sized impeller, and piping modifications to bypass the slush stock chest and related equipment. The objective of this impact evaluation was to assess how much electrical energy is being saved at Scott Paper as a result of the E120,098 to install, and Scott Paper received payment of $82,232 (in 1993 dollars) from Bonneville for the acquisition of energy savings. Pacific Northwest Laboratory calculated the real levelized cost of the energy savings to Bonneville as 14.2 mills/kWh (in 1993 dollars) over the project`s assumed 15-year life, and the real levelized cost to the region as 21.9 mills/kWh, not including transmission and distribution effects. The project would not have been implemented without the acquisition payment from Bonneville and therefore is not a free rider
<em>Pseudomonas campi </em>sp. Nov., a nitrate-reducing bacterium isolated from grassland soil.
A novel strain was isolated from grassland soil that has the potential to assimilate ammonium by the reduction of nitrate in the presence of oxygen. Whole genome sequence analysis revealed the presence of an assimilatory cytoplasmic nitrate reductase gene nasA and the assimilatory nitrite reductase genes nirBD which are involved in the sequential reduction of nitrate to nitrite and further to ammonium, respectively. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolate represents a member of the genus Pseudomonas. The closest phylogenetic neighbours based on 16S rRNA gene sequence analysis are the type strains of Pseudomonas peli (98.17%) and Pseudomonas guineae (98.03%). In contrast, phylogenomic analysis revealed a close relationship to Pseudomonas alcaligenes. Computation of the average nucleotide identity (ANI) and digital DNAâDNA hybridization (dDDH) with the closest phylogenetic neighbours of S1-A32-2 revealed genetic differences at the species level, which were further substantiated by differences in several physiological characteristics. On the basis of these results, it was concluded that the soil isolate represents a novel species of the genus Pseudomonas, for which the name Pseu-domonas campi sp. nov. (type strain S1-A32-2 =LMG 31521 =DSM 110222 ) is proposed. T T T
