In 1937/38 representative mollusc collections were made in Jakarta Bay (West Java, Indonesia). New data from here and the adjacent offshore Thousand Islands archipelago (Kepulauan Seribu) became available in 2005. Although collecting efforts and sampling methods differed, a comparison of the molluscan fauna of Jakarta Bay between 1937/38 and 2005 reveals a distinct deterioration. From 1937 to 2...

Neutron diffraction with isotopic substitution has been used to investigate the liquid structures of propylene carbonate and glycerol carbonate. C-HO[double bond, length as m-dash]C hydrogen-bonding motifs dominate the local structure of propylene carbonate, giving rise to the formation of head-to-tail correlated chains of molecules. In contrast, glycerol carbonate exhibits a more disordered st...

Protonatedweak acids commonly used inmicrobial electrolysis cell (MEC) solutions can affect the hydrogen evolution reaction (HER) through weak acid catalysis, and by lowering solution resistance between the anode and the cathode. Weak acid catalysis of the HER with protonated phosphate, acetate, and carbonate electrolyte species improved MEC performance by lowering the cathode’s overpotential b...

Our previous research has demonstrated that dissolved organic matter (DOM) influences calcium carbonate mineral formation in surface and ground water. To better understand DOM mediation of carbonate precipitation and DOM co-precipitation and/or incorporation with carbonate minerals, we characterized the content and speciation of DOM in carbonate minerals and in the lake water of Pyramid Lake, N...

Cells of Candida parapsilosis were extracted sequentially with different organic solvents. The sodium carbonate wash of the methanol extract showed carcinogenic activity in mice as demonstrated by the appearance of 6 sarcomas at the site of injection in a group of 16 animals. Suggestive carcinogenic activity in the appearance of subcutaneous sarcomas and increased frequency of leukemias and pul...

We study the solvation of molecules and ions that are key in context molten carbonate electrolyser cells using first-principles simulations. Focusing on electroreduction CO2 to CO a medium, we investigate both reactant product eutectic LiKCO3 (containing 62% Li2CO3, 38% K2CO3). is found spontaneously react with form transient pyrocarbonate species, C2O52−. To similar reaction could occur CO32− ...

The Dorood oilfield is located offshore in the northern part of the Persian Gulf. It partly underlies the Kharg Island. The Neocomian Fahliyan Formation represents the high-quality reservoir in the oilfield. It includes five carbonate members: The Manifa, Middle and Upper Yamama, Khami and Lower Ratawi. The Fahliyan Formation in the studied well attains a thickness of 378.1 m and mainly consist...

Redox reactions play key roles in intra- and inter-cellular signaling, and in adaptative processes of tissues towards stress. Among the major free radicals with essential functions in cells are reactive oxygen species (ROS) including superoxide anion (O2 (•-)), hydroxyl radical ((•)OH) and reactive nitrogen species (RNS) such as nitric oxide ((•)NO). In this article, we review the forgotten and...

The new neopterygian genus Ticinolepis, including two new species T. longaeva and T. crassidens is described from Middle Triassic carbonate platform deposits of the Monte San Giorgio. The anatomy of this fish shows a mosaic of halecomorph and ginglymodian characters and, thus, the new taxon probably represents a basal holostean. During the latest Anisian to earliest Ladinian the two new species...
