Dynamic Initiation Fracture Toughness Determination and Full-field Strain Measurements of Rock Material

The purpose of this paper is to present a detailed experimental procedure for the quantitative determination of initiation fracture toughness and full-field strain measurement of rock material under dynamic loads. Notched semi-circular bending tests were c ...

Global distribution and climate forcing of marine organic aerosol-Part 1. Model improvements and evaluation

Yi Zhang, Athanasios Nenes

Marine organic aerosol emissions have been implemented and evaluated within the National Center of Atmospheric Research (NCAR)'s Community Atmosphere Model (CAM5) with the Pacific Northwest National Laboratory's 7-mode Modal Aerosol Module (MAM-7). Emissio ...

Exopolysaccharides produced by bacteria isolated from the pelagic Southern Ocean - Role in Fe binding, chemical reactivity, and bioavailability

Enrica Alasonati

As a result of ubiquitous excretion by micro-organisms, extracellular polymeric substances are reported in high concentrations in marine systems. The majority of this material is exopolysaccharide (EPS). Despite previous studies showing that EPS can affect ...

Dynamics of Microbial Community Structure of and Enhanced Biological Phosphorus Removal by Aerobic Granules Cultivated on Propionate or Acetate

Christof Holliger, Graciela Gonzalez Gil

Aerobic granules are dense microbial aggregates with the potential to replace floccular sludge for the treatment of wastewaters. In bubble-column sequencing batch reactors, distinct microbial populations dominated propionate-and acetate-cultivated aerobic ...

Cloud condensation nuclei activity of isoprene secondary organic aerosol

Athanasios Nenes, Spyros Pandis

This work explores the cloud condensation nuclei (CCN) activity of isoprene secondary organic aerosol (SOA), likely a significant source of global organic particulate matter and CCN, produced from the oxidation with OH from HONO/HOOH photolysis in a temper ...

Products of abiotic U(VI) reduction by biogenic magnetite and vivianite

Rizlan Bernier-Latmani, Elena Suvorova Buffat, Harish Veeramani, Jonathan Sharp, Daniel Scott Alessi

Reductive immobilization of uranium by the stimulation of dissimilatory metal-reducing bacteria (DMRB) has been investigated as a remediation strategy for subsurface U(VI) contamination. In those environments, DMRB may utilize a variety of electron accepto ...

Towards an Autonomous Evolution of Non-Biological Physical Organisms

Francesco Mondada, Michael Bonani, Stéphane Magnenat, Roderich Gross, Lorenz Küchler

We propose an experimental study where simplistic organ- isms rise from inanimate matter and evolve solely through physical interactions. These organisms are composed of three types of macroscopic building blocks floating in an agitated medium. The dynamis ...

Calorimetry and thermodynamic aspects of heterotrophic, mixotrophic, and phototrophic growth

Urs von Stockar, Ian William Marison

A simple stoichiometric model is proposed linking the biomass yield to the enthalpy and Gibbs energy changes in chemo-heterotrophic, mixotrophic, and photo-autotrophic microbial growth. A comparison with calorimetric experiments on the algae Chlorella vulg ...

Isotopic analysis of cyanobacterial nitrogen fixation associated with subarctic lichen and bryophyte species

Konstantin Svetlozarov Gavazov

Dinitrogen fixation by cyanobacteria is of particular importance for the nutrient economy of cold biomes, constituting the main pathway for new N supplies to tundra ecosystems. It is prevalent in cyanobacterial colonies on bryophytes and in obligate associ ...
