Última Animal experimentation and scientific knowledge: a thought style? 60 Tréz,Thales de Astrogildo e. Animal experimentation, besides a research method extensively applied in the production of scientific knowledge, is also considered essential to science and with undeniable historical relevance in advances in human health. In this survey, a questionnaire was applied to a group of researchers involved with research based on non-animal models (n =18), and to another group involved with research based on animal models (n =18). The data analysis was grounded in Ludwik Fleck (1896 -1961) epistemological assumptions. The results suggested that there are at least two thought styles operating in consonance on the same research problem (advances in human health conditions) with significantly different conceptions not only concerning the research practices involved,...

Ano: 1990 URL: http://eprints.nwisrl.ars.usda.gov/539/1/716.pdf Anatomy of a field trial: Wood-based biochar and compost influences a Pacific Northwest soil 18 Ippolito, J.A.; Grob, J; Donnelly, A. Biochar land application research in elevated rainfall areas (980 millimeters of annual rainfall) of the U.S. Pacific Northwest is lacking. A proof-of-concept field study examined the effects of spruce-pine-fir wood chip biochar (slow pyrolysis; 450-500 degrees Celsius; 35 megagrams per hectare), dairy manure compost (105 megagrams per hectare), compost + biochar (35 and 105 megagrams per hectare, respectively), and a control (no biochar or compost) on glacially altered soil (sandy or loamy skeletal, isotonic, mesic humic or aquic Dystroxerepts) chemical properties and growth characteristics of vetch and sweet corn over a growing season. In-season liming (5.4 megagrams per hectare) occurred to raise the soil pH for adequate crop growth. Biochar, alone...
