Strontium isotope fractionation of planktic foraminifera and inorganic calcite
We have investigated the strontium isotope fractionation (Δ88/86Srcarb–aq) between inorganic calcite and aqueous Sr2+ ions by precipitation experiments at a constant temperature of 25 °C andExpand
Thermovibrio ruber gen. nov., sp. nov., an extremely thermophilic, chemolithoautotrophic, nitrate-reducing bacterium that forms a deep branch within the phylum Aquificae.
A novel, extremely thermophilic, chemolithoautotrophic bacterium isolated from the submarine hydrothermal system off the beach of Lihir Island, Papua New Guinea, was found to represent a novel genus for which the name Thermovibrio is proposed. Expand
Constraining the marine strontium budget with natural strontium isotope fractionations (87Sr/86Sr∗, δ88/86Sr) of carbonates, hydrothermal solutions and river waters
We present strontium (Sr) isotope ratios that, unlike traditional 87Sr/86Sr data, are not normalized to a fixed 88Sr/86Sr ratio of 8.375209 (defined as δ88/86Sr = 0 relative to NIST SRM 987).Expand
Millennial-scale climate variability during the last 12.5 ka recorded in a Caribbean speleothem
Abstract We present a speleothem stable oxygen isotope record for the last 12.5 ka based on two stalagmites from western Cuba. The δ18O signal is interpreted to represent past precipitationExpand
Photocurrents generated by bacteriorhodopsin adsorbed on nano-black lipid membranes.
The membrane system exhibits a very high long-term stability with the advantage that not only transient but also stationary currents are recordable, and adds the proton ionophore carbonyl cyanide-m-chlorophenylhydrazone increases, resulting in a higher stationary current, which proves that proton conductance occurs across the nano-BLMs. Expand
Weapons, fighters and combat: spears and swords in Early Bronze Age Scandinavia
This article deals with the use-wear analysis of 204 weapons of Period I of the Early Nordic Bronze Age. The analysed sample contained 154 spearheads and 50 swords and was made up of approximatelyExpand
Using the Capability Approach to Conceptualise Inequality in Archaeology: the Case of the Late Neolithic Bosnian Site Okolište c. 5200–4600 bce
The past few decades have witnessed a growing realisation that market-based measures of human well-being—measures that centre on income and consumption distributions—miss some other perhaps even moreExpand
Tales of Hoards and Swordfighters in Early Bronze Age Scandinavia: The Brand New and the Broken
This article focuses on the complexity of Early Bronze Age weapon depositions. While some of the deposited weapons have been disabled by intentional breakage, others seem to be more or less unused. AExpand
Weapon and tool use during the Nordic Bronze Age
The article is based on wear analysis carried out on 101 bladed objects including swords, spears, daggers, and knives. They are dating mostly to the Early Nordic Bronze Age. Wear marks vary over timeExpand
of carbonates, hydrothermal solutions and river waters
We present strontium (Sr) isotope ratios that, unlike traditional 87 Sr/ 86 Sr data, are not normalized to a fixed 88 Sr/ 86 Sr ratio of 8.375209 (defined as d 88/86 Sr = 0 relative to NIST SRM 987).Expand
