Late Pleistocene loess-palaeosol sequences are widespread in the Vojvodina region, with thicknesses reaching a maximum of about 20 m. Our investigations include more than 40 of these loess sections. Geochronology of the last glacial loess-palaeosol sequences, based on luminescence dating and amino acid racemisation, provides correlations between Upper(More)
Four loess units and three paleopedological layers are preserved in the ~8 m thick Petrovaradin exposure, Vojvodina, Serbia. Amino acid geochronology provides stratigraphic correlations between loess units L1 and L2 at Petrovaradin with loess of glacial cycles B and C, respectively, at other Central European localities. Magnetic susceptibility and(More)
[1] Four loess units and three paleosol layers are preserved in the Irig brickyard, Vojvodina, Serbia. Amino acid geochronology provides stratigraphic correlations between loess units V-L1 and V-L2 at the Irig section with loess of glacial cycles B and C, respectively, described from other central European localities. Luminescence dating results for the(More)
SIGNIFICANCE OF WATER-RELATED FEATURES ON MARS MAY 2010 EILEEN M. MCGOWAN, B.A., SALEM STATE COLLEGE M.S., SALEM STATE COLLEGE Ph.D., UNIVERSITY OF MASSACHUSETTS Directed by: Professor George E. McGill The debate on whether water exists on Mars has been resolved by recent data from the Mars Phoenix Polar Lander. The lander found water ice just below the(More)
This paper presents the results of applying two different types of neural networks in two different approaches to the sensor validation problem. The first approach uses a functional approximation neural network as part of a nonlinear observer in a modelbased approach to analytical redundancy. The second approach uses an auto-associative neural network to(More)
a r t i c l e i n f o The oxygen isotopic composition of land-snail shells may provide insight into the source region and trajectory of precipitation. Last glacial maximum (LGM) gastropod shells were sampled from loess from Belgium to Serbia and modern land-snail shells both record δ 18 O values between 0‰ and − 5‰. There are significant differences in mean(More)
The National Wildlife Refuge system is a vital resource for the protection and conservation of biodiversity and biological integrity in the United States. Surveys were conducted to determine the spatial and temporal patterns of fish, macroinvertebrate, and crayfish populations in two watersheds that encompass three refuges in southern Indiana. The Patoka(More)
