Residual effects of natural Zn chelates on navy bean response, Zn leaching and soil Zn status
TL;DR: In this article, a greenhouse experiment was conducted on weakly acidic and calcareous soils to evaluate the aging and residual effects of three natural organic Zn chelates [Zn-ethylenediaminediaminedisuccinate, Zn-EDDS, and Znpolyhydroxyphenylcarboxylate] each administered in a single application to a first navy bean (Phaseolus vulgaris L.) crop at several different Zn application rates.

Granulometrical, mineralogical and geochemical characterization of loess deposits in the Tajo Basin
TL;DR: In this article, the first results of investigations on a loess sequence in the middle Tajo Valley in central Spain were presented, where detailed granulometrical, mineralogical, geochemical, and grain morphological analyses help to give a first overview on character and composition of these deposits.

Mineral-Content and Particle-Size Effects on the Colloidal Properties of Concentrated Lateritic Suspensions
TL;DR: In this article, the rheological behavior of concentrated lateritic suspensions from Cuba is affected by mineral composition and particle size, and the electrokinetic curves suggest that heterocoagulation is present in all samples, with a zeta potential minimum at the isoelectric point.

Mineralogy, O18/O16, and D/H Ratios of Clay-Rich Sediments from Deep Sea Drilling Project Site 180, Aleutian Trench1
Eric Eslinger,Hsueh-Wen Yeh +1 more
TL;DR: Mineralogy, O18/O16, and D/H ratios have been determined in five size fractions (2.0µm) of seven samples taken from 500 m of Pleistocene deep-sea sediments cored at Deep Sea Drilling Project Site 180 in the Aleutian Trench as discussed by the authors.

Petrographic and geochemical evidence for long-standing supply of raw materials in neolithic pottery (mendandia site, spain)
TL;DR: In this paper, petrographic data showed two different methods of raw materials manufacture-intentionally tempered pottery (ITP), using calcite and/or limestone and grog, and naturally or nonintentionally tempering pottery.
