Distribution of local 137Cs anomalies on the seafloor near the Fukushima Dai-ichi Nuclear Power Plant
Abstract An estimated 3.5±0.7×1015 Bq of 137Cs is thought to have been discharged into the ocean following the melt down at Fukushima Dai-ichi Nuclear Power Plant (F1NPP). While efforts have been made to monitor seafloor...

Misinterpretation of categorical rate ratios and inappropriate exposure–response model fitting can lead to biased estimates of risk: Ethylene oxide case study
Abstract There are pitfalls associated with exposure–response modeling of human epidemiological data based on rate ratios (RRs). Exposure–response modeling is best based on individual data, when available, rather than being based on summary results...

Metal Concentrations and Metal Deposition in Deep Geothermal Wells at the Reykjanes High-temperature Area, Iceland
Abstract Sulfide scale is precipitating at 2770 m depth and ∼330°C in well RN-17B from unboiled, seawater-dominated hydrothermal fluids. The scale consists of well-crystallized pyrrhotite with minor sphalerite, and traces of galena, pyrite, and...

Particles emitted during the stops of an urban bus fuelled with ethanol–biodiesel–diesel blends
Abstract Urban buses with diesel engines produce NOx and particulate matter emissions thus affecting local city pollution. During stops, due to traffic lights, programmed stops, etc., pollutants are emitted close to people, being damaging to their...

Papuan Bird’s Head Seascape: Emerging threats and challenges in the global center of marine biodiversity
Abstract The Bird’s Head Seascape located in eastern Indonesia is the global epicenter of tropical shallow water marine biodiversity with over 600 species of corals and 1,638 species of coral reef fishes. The Seascape also includes critical habitats ...

Assessing frost susceptibility of soils using PCHeave
Abstract This paper first presents a simple frost heave model. Frost heave is assumed to be caused by the formation of ice lenses in a freezing soil. The formation of ice lenses is governed by the Clapeyron equation of thermodynamics and relies on...

Strontium Isotope Fractionation in Soils and Pedogenic Processes
Abstract The stable isotope composition of strontium (the ratio 88Sr/86Sr expressed as δ88/86Sr) showed significant fractionation in mountain soils of the Judea Highland. In order to understand this phenomenon, we studied the elemental composition...

Source Identification of Traffic-Related Ultrafine Particles Data Mining Contest
Abstract Atmospheric particulate matter (PM) is a complex mixture of microscopic particles with different shapes, sizes and chemical compositions. The ultrafine size fraction of PM consists of particles with diameters less than 100nm. In urban...

Automated classification of single airborne particles from two-dimensional angle-resolved optical scattering (TAOS) patterns by non-linear filtering
Abstract Measurement of two-dimensional angle-resolved optical scattering (TAOS) patterns is an attractive technique for detecting and characterizing micron-sized airborne particles. In general, the interpretation of these patterns and the retrieval ...

Modelling of A Pulsating Heat Pipe and Startup Asymptotics
Abstract Pulsating heat pipes (PHP) can be an effcient solution to heat transfer problems in many applications. However, mathematical modelling of a PHP system still has many challenging issues due to the complexity and multiphysics nature of the...

Recursive plasma wake formation on the Moon and its effect on polar volatiles
Abstract Solar wind plasma flows almost horizontally in near-terminator regions of the Moon. One question is how does this plasma flow around topographic features like near-terminator mountains and polar craters? We present kinetic simulations of...

Flow regulation alters alpine river thermal regimes
Summary Impacts of anthropogenic flow regulation on the thermal regimes of alpine river systems are poorly understood. This is surprising given the importance of water temperature for river ecosystems and the widespread regulation of mountain rivers ...

Experimental and simulation studies of iron oxides for geochemical fixation of CO2–SO2 gas mixtures
Abstract Iron-bearing minerals are reactive phases of the subsurface environment and could potentially trap CO2–SO2 gas mixtures derived from fossil fuel combustion processes by their conversion to siderite (FeCO3) and dissolved sulfate. Changes in...

How simple can we make models for CO2 injection, migration, and leakage?
Abstract Analysis of geological storage of CO2 almost always involves some set of computational models that provide a mathematical descri iption of the problem. These models can have many purposes, but ultimate they should be able to answer...

CO2 leakage test in a shallow aquifer for investigating the geochemical impact of CO2 on groundwater and for developing monitoring methods and concepts
Abstract CO2 leakage from subsurface storage sites is one of the main concerns connected with the CCS technology. As CO2 leakages into near surface formations appear to be very unlikely within pilot CCS projects, the aim of this work is to emulate a ...

Researches on Photosynthetic Efficiency of cassava-peanut Intercropping Impacted by Total Solar Eclipse
Abstract On July 22nd, 2009, the total solar eclipse spectacle occurred in Yangtze River in central China. By setting cassavaand- peanut intercropping, we used LI-6400 to study the diurnal variation of photosynthetic efficiency impacted by total...

CCS from multiple sources to offshore storage site complex via ship transport
Abstract For the developed countries whose increase of demand of fuel energy has become slow, Japan for example, CCS would need to be deployed under the given conditions, such as geographical localities of large emission sources, social conditions...

CCS opportunities in the Australian “Industrial Processes” sector
Abstract Greenhouse gas emissions from industrial processes, such as cement manufacturing or steel production, in Australia accounts for more than 40 Mt CO2-e per annum, representing close to 20% of Australia’s potentially sequesterable emissions....
