(2001)'Lying at the interface of the geosphere, biosphere and hydrosphere, soils occupy a central place in ecosystems, and because of this they are sensitive and detailed indicators of past and present environments.'
-
(2003)This chapter illustrates the complexity of extracting paleoenvironmental and paleoclimatic information from preserved soils and discusses examples that show how soil is related to climate and, in turn, the types of climate ...
-
(2006)Soils annually emit between 6.8 and 7.9 Gt CO2 equivalents, mainly as CH4 from intact peatlands and from rice agriculture; as N2O from unmanaged and managed soils; and as CO2 from land-use change. Methane emissions ...
-
(2004)A new genus, Sokurella, represented by the type species S. galaczi sp. nov., is described from the Lower Bathonian near Saratov and assigned to the subfamily Pseudocosmoceratinae (family Parkinsoniidae). The genera ...
-
(2004)Из нижнего бата окрестностей Саратова описан новый род Sokurella, представленный типовым видом S. galaczi sp. nov. и отнесенный к подсемейству Pseudocosmoceratinae (семейство Parkinsoniidae). Приведены краткая характеристика ...
-
(2003)The analysis of variability in Atmospheric Angular Momentum (AAM) and Length of day (LOD) of Abarca del Rio et al. [Ann. Geophys. 18 (2000) 347] is extended to investigate a possible connection with solar activity fluctuations ...
-
(2004)With only a few exceptions the solar photosphere is thought to have retained the mean isotopic composition of the original solar nebula, so that, with some corrections, the photosphere provides a baseline for comparison ...

-
(2006)Cosmogenic radionuclides with distinctive half-lives from chondritic falls were used as natural detectors of galactic cosmic rays (GCR). A unique series of uniform data was obtained for variations in the integral gradients ...
-
(2006)Tidal and momentum interactions of the bodies of the solar system create stable oscillations of the momenta of inertia of the Sun and planets. The laws of momentum conservation are the reasons for synchronous oscillations, ...
-
(2004)For over one hundred years the Ordovician fossil Solenopora Dybowski has been widely considered to be a calcified red alga. The type species, Solenopora spongioides, consists of tubes with longitudinally flexuous walls, ...
-
(2000)The impact of the Fe (III)-reducing bacteria Shewanella alga on the solid phase partitioning of dissolved Sr2+ was investigated in a series of experiments using live cells, dead cells (heat-treated at 80°C) and isolated ...
-
(1996)Although solid solutions play important roles in controlling the concentrations of minor metal ions in natural waters, uncertainties regarding their compositions, thermodynamics, and kinetics usually prevent them from being ...
-
(2006)Synthetic (Ca1-xNax)(Ti1-x Nbx)OSiO4 and Ca(Ti1-2x NbxAlx)OSiO4 solid solutions have been prepared for x = 0.1 and 0.2 by ceramic methods and their crystal structure determined by Rietveld analysis. At ambient conditions, ...
-
(2005)The thermodynamics of dilute Eu-calcite solid solutions formed under widely different pH-pCO 2 conditions at T = 25°C and p = 1 bar were investigated using three sets of Eu(III) uptake experiments, two of which were taken ...
-
(1988)The distribution of atoms in lattices of minerals such as alkali feldspars or orthopyroxenes have long been used to estimate the temperature of natural processes. We describe an approach to determining the kinetics of ...
-
(2000)Solid state CP/MAS 13C nuclear magnetic resonance (NMR) study of the insoluble organic fraction isolated by HF/HCl treatment under an inert atmosphere from the Orgueil and Murchison carbonaceous meteorites is reported. ...
-
(1998)Lode, a dioctahedral illite-rich clay from Latvia belonging to the mica group of clay minerals, undergoes thermal transformation via a series of structurally disordered intermediate phases. Despite containing high levels ...
-
(2003)The solubility of crystalline Mg(OH)2(cr) was determined by measuring the equilibrium H+ concentration in water, 0.01-2.7 m MgCl2, 0.1-5.6 m NaCl, and in mixtures of 0.5 and 5.0 m NaCl containing 0.01-0.05 m MgCl2. In MgCl2 ...
-
(1998)Solid-liquid phase equilibria and equilibrium phase relationships of U(VI) in up to 5 m NaCl solutions were studied by analyzing the precipitation process in initially oversaturated solutions at different pH values. ...
