  • Methane and carbon dioxide emission from two pig finishing barns

    Received for publication July 22, 2007. Agricultural activities are an important source of greenhouse gases. However, comprehensive, long-term, and high-quality measurement data of these gases are lacking. This article presents a field study of CH4 and CO2 emission from two 1100-head mechanically ventilated pig (Sus scrofa) finishing barns (B1 and B2) with shallow manure flushing systems and ...

  • Case study - I am satisfied

    Urs Berger from Switzerland is an experienced pig farmer and he and his family is the second generation on the 250 acres farm in the village Oberbottigen. In 2013 he installed the DACS ventilation system in a new pig house - housing 1000 pigs for fattening. In the new house the pigs have access to an outdoor enclosure. Nevertheless they often choose to stay indoor - thanks to the very efficient ...

  • Image-based measurement of alveoli volume expansion in an animal model of a diseased lung

    This research aims to improve ventilation protocols in critical care by using appropriate computer models that take into account the essential lung mechanics. This paper automatically tracks the boundary of individual or groups of alveoli, and converts this into a pressure volume curve for three different types of alveoli. Schiller et al. investigate the inflation and deflation of alveoli in a ...

  • Pilot scale facility to determine gaseous emissions from livestock slurry during storage

    Livestock production is a growing source of air pollution, locally and to the wider environment. Improved livestock manure management has the potential to reduce environmental impacts, but there is a need for methodologies to precisely quantify emissions. This paper describes and evaluates a novel storage facility for livestock slurry consisting of eight 6.5-m3 cylindrical units. The stores may ...

  • Worming the way to finished compost

    SCREENING AND GRINDING When materials from CR&R and other generators are unloaded, a preliminary screening separates out nonorganic contaminants.    Even though there are source separated programs in places like Temecula and Lake Elsinore, there is the occasional appearance of plastic and glass that needs to be sorted out. Next, Bodlak’s crews put materials through a Vermeer tub ...

  • Compost science journal of advocacy and foresight

    SEVERAL months ago, I started on a journey through the pages of Compost Science, beginning with the Spring, 1960 inaugural issue. I was confident that I could whip through the articles and news items in the several hundred issues of the magazine between 1960 and 2009, and be prepared to write this article for BioCycle’s 50th Anniversary Commemorative Edition. Granted, there were interruptions, ...
