OBJECTIVE To assess the efficacy of prophylactic hoof health examination and trimming during midlactation at reducing the incidence of lameness during late lactation in dairy cows. DESIGN Randomized field trial. ANIMALS 333 Holstein cows. PROCEDURES Cows without apparent lameness were randomly allocated into 1 of 2 groups approximately 204 days after calving. Cows allocated to the treatme...

Most of the industrial parts are designed as trimmed NURBS. Today’s graphics hardware supports the high-speed display of polygonal objects consisting of triangles. This means that analytical surfaces (like NURBS) need to be triangulated so they can be displayed by 3D graphics cards. To be able to control the quality of the tesselated model, the triangulation should be carried out with a given e...

BACKGROUND "Facing the block" is defined as trimming tissue on a microtome from peripheral or deep surgical margins before sectioning. Facing includes trimming performed intentionally but unnecessarily, accidentally, or out of necessity because of one's choice of embedding and freezing method. OBJECTIVE To assess whether facing the block is associated with a greater number of stages to clear ...

BACKGROUND Hypereosinophilic syndrome is a hematologic disorder in which the eosinophils proliferate. Oral Janus kinase inhibitors are known to be effective treating hypereosinophilic syndrome. Janus kinase inhibitors have also demonstrated efficacy in alopecia. Madarosis is a condition in which the eyelashes are missing or absent and can been seen in alopecia patients. CASE PRESENTATION We p...

This paper presents a new approach to rendering triangular algebraic free form surfaces. A hierarchical subdivision of the surface with associated tight bounding volumes provides for quick identification of the surface regions likely to be hit by a ray. For each leaf of the hierarchy an approximation to the corresponding surface region is stored. The approximation is used to compute a good star...

Comparative studies on resin-dentin bond strength and failure mode were performed between the conventional tensile test and the microtensile test with non-trimming small specimens, 1 x 1 mm in cross-section, for two brands of dentin bonding systems. The fracture surface of the conventional large specimen showed a catastrophic cohesive failure in dentin at its center and a lesser adhesive failur...
