A non-classical view on calcium oxalate precipitation and the role of citrate
Nature Communications, 2017 The formation mechanism of abundant calcium oxalate biomaterials is unresolved. Here the authors show the early stages of calcium oxalate formation in pure and citrate-bearing solutions by using a titration set-up in conjunction with solution quenching ...

Theoretical Formulation of the Origin of Cataclysmic Late Heavy Bombardment Era based on the New Perspective of Birth & Evolution of Solar Systems [PDF]
arXiv, 2008 Based on the planet-satellite dynamics, a new perspective on the birth and evolution of the Solar System was proposed in 2004. This new perspective has 1:2 Mean Motion Resonance (1:2 MMR, that is Ps/Pj = 2) implicit in itself . This paper has shown that if we assume the sequential birth of the planets with the heaviest, i.e.

Global Challenges, EarlyView.Rainwater harvesting (RWH) has become a hot issue in the present scenario due to intermittent climate change, scanty rainfall, and insufficient surface runoff. Among such, the Konso area in the extreme south of Ethiopia is considered to find effective sites for RWH through multi‐criteria analysis combined with Geographic Information System.

Geological Journal, EarlyView.This work documents how the texture and composition of metamorphic garnet represent a valuable petrological archive capable of deciphering complex thermobaric histories. ABSTRACT In the central sector of the Sanandaj‐Sirjan zone of Iran, the Triassic‐to‐Jurassic ‘Hamedan Phyllites’ metamorphic complex shows a polymetamorphic evolution characterised by ...

Pegmatites of Southern California [PDF]
, 1954 For many years the southern California region has attracted the attention of geologists interested in pegmatites and pegmatite deposits, largely because of the well-known gem and lithium occurrences in San Diego and Riverside Counties. These world-famous

Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background Extra virgin olive oils (EVOOs) are widely consumed but rarely analysed for potentially toxic elements (PTEs), whose concentrations in EVOOs can be significantly influenced by contamination in olive grove soils. As food consumption is the main PTE accumulation pathway in humans, thorough investigation on EVOOs is necessary.

Journal of Quaternary Science, EarlyView.ABSTRACT The Lake Volvi area, part of the region of Macedonia (northern Greece), is a biodiversity hotspot, located in the central part of a major communication corridor connecting the western and eastern parts of the Balkans. The sediment succession from Lake Volvi is investigated here to provide a unique high‐resolution pollen and geochemical record ...

Journal of Quaternary Science, EarlyView.ABSTRACT Openwork mountain block deposits (blockfields, blockstreams) have received much research interest globally given their visual appeal as prominent cold‐region landforms. However, studies have shown that these landforms in both glaciated and non‐glaciated environments are probably of considerable age (pre‐Quaternary), yet the environmental ...
