The method of Boisen and Fernandez [Boisen, S., Fernandez, J.A., 1997. Prediction of total tract digestibility of energy in feedstuffs and pig diets by in vitro analyses, Anim. Feed Sci. Technol. 68, 277–286] for measuring in vitro fecal digestibility of organic matter (OMdv) or in vitro digestible organic matter content (DOMv, g/kg) was used on 113 compound feeds (79 as mash and 34 as pellets)...

Introduction: The Antarctic Meteorite Program has returned over 16,000 meteorites from the ice sheets of the Antarctic. This more than doubles the number of preexisting meteorite collection and adds important and rare specimens to the assemblage. The CM carbonaceous chondrites are of particular interest because of their high organic component. The Antarctic carbonaceous chondrites provide a lar...

Crop yields and root growth were studied in a 6-year trial comparing conventional, organic, and biodynamic methods of fertilization. Intense use of a set of biodynamic preparations, including a nettlecontaining compound preparation, was found to have a balancing effect on the yields of maize and winter wheat. This effect may have been caused by greater root growth and improved root health. Intr...

Objectives: Preliminary calculations indicated that carbonate radical may participate in organic compound removal during AOP application, and that in some cases, this participation might be further enhanced by relatively minor adjustments to the water chemistry, during a pretreatment step. The objectives of this project were to investigate those effects, develop a model for prediction of the ef...

Abstract. The emissions of volatile organic compounds (VOCs) from chemical products (VCPs) – specifically personal care products, cleaning agents, coatings, adhesives, and pesticides are emerging as the largest source petroleum-derived carbon in US cities. Previous work has shown that ambient concentration markers for most VCP categories correlates strongly with population density, except VOCs ...

Ascomata of two truffle species, Tuber borchii and T. asa-foetida, both naturally growing in woodlands of the Basilicata region (southern Italy), were identified on the basis of ascospore morphology and compared under a volatile organic compound profile to determine the particular volatile organic compounds that characterize each taxon. Solid-phase microextraction-gas chromatography-mass spectr...

the tumors in which odontogenic differentiation is fully expressed are the odontomas. odontomas are considered as hamartomas rather than a true neoplasm. these tumors are composed of enamel, dentine, cementum and pulp tissue. it is most commonly associated with the eruption of the teeth. they are usually discovered on routine radiographic examination. in exceptional cases, the odontoma erupts i...

Numerical assessments of global air quality and potential changes in atmospheric chemical constituents require estimates of the surface fluxes of a variety of trace gas species. We have developed a global model to estimate emissions of volatile organic compounds from natural sources (NVOC). Methane is not considered here and has been reviewed in detail elsewhere. The model has a highly resolved...

Volatile organic compound (VOC) profiles are potentially an underutilized class of threat agent signatures that may be exploited in the identification of threat agents. In the present study we first focused on determining if VOC profiles collected from liquid culture headspace could be utilized to differentiate between bacterium of different genus, in this case Bacillus and Yersinia. The second...

An understanding of the gas/particle-phase partitioning of semivolatile compounds is critical in determining atmospheric aerosol formation processes and growth rates, which in turn affect global climate and human health. The Study of Organic Aerosol at Riverside 2005 campaign was performed to gain a better understanding of the factors responsible for aerosol formation and growth in Riverside, C...
