A multi-pollutant and multi-sectorial approach to screening the consistency of emission inventories

Some studies show that significant uncertainties affect emission inventories, which may impeach conclusions based on air-quality model results. These uncertainties re sult from the need to compile a wide variety of information to estimate an emission inventory. In this work, we propose and discuss a screening method to compare two emission...

A compact static birefringent interferometer for the measurement of upper atmospheric winds: concept, design and lab performance

A new compact static wind imaging interferometer, called the Birefringent Doppler Wind Imaging Interferometer (BIDWIN), has been developed for the purpose of observing upper atmospheric winds using suitably isolated airglow emissions. The instrument combines a fieldwidened birefringent delay plate placed between two crossed Wollaston prisms with...

Comment on “Greenhouse gas emissions from marine decommissioned hydrocarbon wells: Leakage detection, monitoring and mitigation strategies” by Christoph Böttner, Matthias Haeckel, Mark Schmidt, Christian Berndt, Lisa Vielstädte, Jakob A. Kutsch, Jens Karstens & Tim Weiß

Global greenhouse gas emissions from residential and commercial building materials and mitigation strategies to 2060

Building stock growth around the world drives extensive material consumption and envir onmental impacts. Future impacts will be dependent on the level and rate of socioeconomic development, along with material use and supply strategies. Here we evaluate material related greenhouse gas (GHG) emissions for residential and commercial buildings...

Quality control of geological voxel models using experts' gaze

Due to an expected increase in geological voxel model data-flow and user demands, the development of improved quality control for such models is crucial. This study explores the potential of a new type of quality control that improves the detection of errors by just using gaze behavior of 12 geological experts. Gaze is used as input for an...

Speech overlap detection in a two-pass speaker diarization system

In this paper we present the two-pass speaker diarization system that we developed for the NIST RT09s evaluation. In the first pass of our system a model for speech overlap detection is generated automatically. This model is used in two ways to reduce the diarization errors due to overlapping speech. First, it is used in a second diarization...

Isolation and characterization of Alicycliphilus denitrificans strain BC, which grows on benzene with chlorate as the electron acceptor

A bacterium, strain BC, was isolated from a benzene-degrading chlorate-reducing enrichment culture. Strain BC degrades benzene in conjunction with chlorate reduction. Cells of strain BC are short rods that are 0.6 μm wide and 1 to 2 μm long, are motile, and stain gram negative. Strain BC grows on benzene and some other aromatic compounds with...

A new method for screening and isolation of hypersecretion mutants in Aspergillus niger

Although filamentous fungi have a unique property of secreting a large amount of homologous extracellular proteins, the use of filamentous fungi as hosts for the production of heterologous proteins is limited because of the low production levels that are generally reached. Here, we report a general screening method for the isolation of mutants...

Soil effects on GPR detection of buried non-metallic mines

Landmines are a major problem in many areas of the world. In spite of the fact that many different types of landmine sensors have been developed, the detection of non-metallic landmines remains very difficult. The objective of this contribution is to synthesize our work related to the effects of soil texture and soil water content on the...

In vivo cytokine profiles in allergic and irritant contact dermatitis

Local cytokine profiles in skin biopsies from allergic and irritant patch test reactions were determined by in vivo immunohistochemistry to differentiate between these 2 clinically identical afflictions especially at the time of final reading in diagnostic patch testing. Biopsies were taken from established allergic persons after specific...
