| Dockage levels in U.S. wheat exports have been a continuing concern. Recent proposals have focused on changes in U.S. grain standards that would include dockage limits. In this report, dockage trends and practices were documented and effects of prospective changes evaluated. Results indicate the marketing system is currently working effectively with costs of extra cleaning being borne partly by buyers, elevators, and to some extent farmers. Suggested mandates would increase cleaning and result in increased costs (ultimately discounts to growers) and potentially in shifts in grades purchased. Proposed changes in grain standards are also a departure from the generally followed approach to regulation in the United States. In this case, a regulation is... |

| Abstract Osteologic collections are used as an aid to scientific and teaching activities, to provide information on specific vertebrate characteristics, such as body support, posture, mode of locomotion, feeding habits and ecological niche. Known techniques for cleaning entire skeletons or mammalian skulls vary according to the destination of the material, the objective of the study, the taxonomic group, and the size of the specimen. The objective of this study was to test three different methods of maceration for cleaning bat skulls (traditional biological maceration, controlled biological maceration using Dermestes maculatus and controlled biological maceration using necrophagous fly larvae). The methods were carried out during five consecutive months,... |

| This paper assesses the performance of three ceramic membranes of average pore size 50 nm, 200 nm and 1.4 tan in the treatment of the press liquor resulting from a compaction operation of sardine by-products. To this end, 2 L of pre-filtered press liquor with an average protein content of 44 g/L were filtered during 3 h through the three membranes assayed. Unexpectedly, the membrane of larger pore size, presented the lowest values for the flux of permeate at steady state at 20 L/(m(2) h), while its average protein rejection (77%) was similar to that observed in the membrane of 200 nm. This fact was attributed to the difference in material of its active layer (a-alumina instead of zirconite). The cleaning efficiency of the membranes was assessed by the COD... |

| Castor bean fruits are already used for biodiesel production but obtaining quality seeds is still a challenge. Seed cleaning improves lot quality but little is known about the effects of upgrading castor bean seed lots on a densimetric table. The objective of this study was to evaluate the influence of cleaning castor bean seed lots on a densimetric table on their physical, physiological and sanitary characteristics. Two commercial lots of the AL Guarani 2002 cultivar, separated into five categories according to their classification on a densimetric table (uncleaned and low, low intermediate, high intermediate and high outlets), were evaluated. Tests for the yield, one-thousand seed weight, germination, seedling emergence, electrical conductivity and seed... |
