The paleoclimatic message from the polymodal grain-size distribution of late Pleistocene-early Holocene Pampean loess (Argentina)
(Elsevier B.V., 2020-01)
Wind-blown dust deposits are considered one of the most important terrestrial archives for past climate change studies. In the Southern Hemisphere, the Pampean loess is the most extensive paleo-dust record, whose origin ...
Comparison of quality attributes of refined and whole wheat extruded pasta
(Elsevier Science, 2018-03)
This work aimed at developing pasta with different types of flour to evaluate how different raw materials and particle size affect pasta quality. Triticum aestivum flour was obtained from two cultivars: Klein Guerrero and ...
Radarfacies and sedimentological analysis: study of sedimentary substrate from an archaeological site (shell mound), southern Brazil
(Sage Publications Ltd, 2015-08-01)
Integrated results of GPR (Ground Penetrating Radar) and sedimentological analysis are presented for the Jabuticabeira II archaeological site (shell mound), Santa Catarina, Brazil. By means of radarfacies identification, ...
Modern pollen source and spatial distribution from surface lake sediments in the southwestern Pampa grasslands, Argentina: Implications to interpret Holocene pollen records
(Elsevier Science, 2020-06)
In the Pampa grasslands of Argentina nothing is known about the transport, deposition and spatial distribution of pollen in lakes. To analyze and understand how well lake surface sediment pollen assemblages reflect the ...
Bridging hydraulic diffusivity from aquifer to particle-size scale: a study on loess sediments from southwest Hungary
(Taylor &Francis Ltd, 2015-02-01)
In situ megascale hydraulic diffusivities (D) of a confined loess aquifer were estimated at various scales (10 <= L <= 1500 m) by a finite difference model, and laboratory microscale diffusivities of a loess sample ...
Sediment grain size distribution and heavy metals determination in a dam on the Parana River at Ilha Solteira, Brazil
(Taylor & Francis Inc, 2009-07-15)
This paper reports on a preliminary evaluation of the grain size distribution of cadmium, lead and copper in sediment from Catarina Beach, Ilha Solteira, in the state of São Paulo, Brazil. Surface sediments were fractionated ...
