ISSN: 1438-1168Source: Springer Online Journal Archives 1860-2000Topics: GeosciencesDescription / Table of Contents: Zusammenfassung Fünfzehn Schneeproben wurden in der Nähe (1.5–8 km) von Kupfer-Nickel-Minen und Mitten in Zapoljarnij, Nikel und Monchegorsk auf der Halbinsel Kola, NW Rußland, am Ende des Winters 1995/96 genommen. Anschliffe von Schneefilterrückständen wurden für die mikroskopischen Untersuchungen Bowie für qualitative und quantitative Mikrosondenanalytik angefertigt. Die in den Anschliffen beobachteten Phasen sind teils geogener1, teils technogener2 Herkunft. Die geogenen Partikel sind Teil der lokalen Staubemissionen (Pechenga Ni-Cu-Tagebaue, Transport und Aufbereitung von Erzen). Die technogenen Partikel repräsentieren ein breites Spektrum unterschiedlich zusammengesetzter Sulphide (Ni-Cu-Fe-Co), Oxyde (Fe-Ni-Cu), metallischer Phasen und Legierungen (Ni-Cu-Fe-Co), sowie Schlacke-Partikel und Koks. Variationen der Zusammensetzung und im Auftreten dieser Phasen ermöglichen Rückschlüsse auf die im Prozess eingesetzten Erze und auf verschiedene Stadien der Prozesstechnik (z.B. Rösten, Schmelzen auf Cu-Ni Stein, Konvertieren auf Cu-Ni Feinstein, Raffinieren) in den lokalen Haupternittenten. Ausserdem konnten PGE-führende Sulphide (Pentlandit mit 0.2–0.3 Gew% Pd) und separate PGE-Phasen in den partikulären Emissionen von Zapoljarnij and Monchegorsk identifiziert werden.Notes: Summary Fifteen snow samples were collected at the end of the 1995/96 winter in the vicinity (1.5–8 km) of the copper-nickel processing plants at Zapoljarnij, Nikel and Monchegorsk on the Kola Peninsula, NW Russia. Polished sections were made from the snow filter residues for microscopic and qualitative and quantitative electron microprobe investigations. Particles in snow are derived from either geogenic1, or technogenic sources2. Ore particles from two different Ni-Cu deposits can be identified in the snow: i) local Pechenga ore and ii) imported ore from Norilsk-Talnakh. Technogenic particles consist of a wide spectrum of sulphides (Ni-Cu-Fe-Co), oxides (Fe-Ni-Cu), metallic phases and alloys (Ni-Cu-Fe-Co), as well as slag particles and coke. Differences in the processing technologies used in the three plants (e.g. roasting, smelting to Cu-Ni matte, converting, refining) can be deduced from the mineralogy of the particulate emissions. The mineralogy of particulate matter in snow is characteristic for each emitter and can thus be used to fingerprint different sources. PGE-bearing sulphides (pentlandite with 0.2–0.3 wt% Pd) have been observed in the particulate emissions from Zapoljarnij and discrete PGE-phases at Monchegorsk.Type of Medium: Electronic ResourceURL: -

ISSN: 1090-6533Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract Small additives of silicon and antimony to a Fe-16% Cr alloy differently affect the segregation of ion-implanted deuterium in this material: silicon increases and antimony decreases the degree of deuterium accumulation. The phenomenon is explained by the impurity type influencing the properties of vacancy clusters in the target metal, which serve as traps for the implanted deuterium.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-0495Keywords: Key words ICP-MS laser ablation ; Tree-ring profiles ; Heavy metals ; Pollution historySource: Springer Online Journal Archives 1860-2000Topics: GeosciencesNotes: Abstract Laser ablation ICP-MS analysis of tree rings provides a rapid and sensitive method for investigating element concentrations and fluctuations in trees along time profiles. Time profiles obtained from pine and birch trees from a strongly polluted area in northwest Russia and a slightly polluted area at the Norwegian-Russian border show that single trees behave rather individualistically in terms of heavy metal contents as observed in the yearly growth rings. The obtained profiles can not be linked to the pollution history of the area. No correlation between pollution levels of the soils and observed metal content in tree rings can be established.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-0495Source: Springer Online Journal Archives 1860-2000Topics: GeosciencesNotes: Abstract Top and bottom samples of overbank sediments were collected at 43 sites within a 12 000 km2 area around the nickel smelter in Nikel and the ore roasting plant at Zapoljarnij, in northwestern Russia. In addition, three detailed overbank profiles were sampled in 10-cm sections from three catchments representing different levels of pollution. All samples were analysed for more than 30 elements by ICP-AES following aqua regia extraction. Results obtained show that overbank sediments represent natural (geogenic) background levels rather well. Although the major pollutants (Co, Cu, Ni and S) are strongly enriched at some places close to industry, overbank sediment is not especially well suited for mapping the extent of airborne contamination in the area. Co, Cu, Ni and S are mobile within the profile collected from the most polluted catchment.Type of Medium: Electronic ResourceURL: -

ISSN: 1090-6525Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract Ozone production during the efflux of oxygen from a supersonic nozzle is studied theoretically and experimentally. The formation kinetics of atomic oxygen in an electrical discharge in the nozzle is analyzed. An experiment is set up using an optimized nozzle with an electrical discharge in its supersonic section. It is shown that the highest ozone content at the nozzle output is attained when the excess concentration of oxygen atoms is produced in the supersonic section of the nozzle.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-9171Source: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Conclusions By condensation of 4-trifluoroacetylresorcinol with cyanoacetic ester, we have obtained 4-trifluoromethyl-7-hydroxy-2-cyanocarbethoxymethylene-2H-1-benzopyran, the structure of which has been proven by an x-ray diffraction investigation. The presence of an elelctron-acceptor group in the 4 position of the benzopyran nucleus leads to a decrease in the degree of charge separation in 2-alkylidenebenzopyrans. We present the lasing characteristics of the compound obtained.Type of Medium: Electronic ResourceURL: -

The rate constants of the mutarotation ofβ-D-arabinose in 50% aqueous ethanol in the presence of the investigated catalysts obey the Bronsted function withβ = 0.84±0.01 at 20°. 2. The thermodynamic parameters of the activation of the mutarotation ofβ-D-arabinose under the action of the investigated catalysts are related by an isokinetic function (β = 250 ± 2K).Type of Medium: Electronic ResourceURL: -

ISSN: 1562-6938Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract The structure of an ion-acoustic forerunner excited by a shock wave in a weakly ionized plasma is studied. It is shown that, when the shock velocity exceeds the ion-acoustic speed, a soliton bunch is produced at the perturbation front. The increase in the shock velocity to a certain critical value is accompanied by an increase in the soliton amplitude. A further increase in velocity leads to an explosive-like collapse of the bunch, which results in a decrease in the medium resistance. This phenomenon is analogous to the “Houston's horse” effect in narrow-channel hydrodynamics.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-8353Source: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract We have obtained thiazoline hydrobromides by reacting unsubstituted thiosemicarbazones of phosphoryl-acetaldehydes with bromoacetal. These thiazoline hydrobromides have the structure of the azine of phosphorylacetaldehyde and 1,3-thiazoln-2-one in the crystal phase. Their dissolution is accompanied by thiazoline-thiazole tautomeric conversion to the hydrobromide of phosphorylacetaladehyde thiazolylhydrazone. Reaction of the 2-methyl-substituted phosphorylacetaldehyde thiosemicarbazone with bromoacetal leaas to the hydrobromide of phosphorylacetaldehyde N-methyl-N-2-(1,3-thiazolyl)hydrazone, the thiazole structure of the heterocycle of this compound is also retained when it is dissolved, due to the impossibility of tautomeric conversions due to the structural features. In all cases, salt formation occurs at the endocyclic nitrogen atom. The conversion of salt-like compounds to free bases does not lead to a change in the thiazole structure of the heterocycle.Type of Medium: Electronic ResourceURL: -
