A computat ional model for the acquisition of knowledge from encyclopedic texts is described. The model has been implemented in a program, called SNOWY, that reads unedited texts from The World Book Encyclopedia, and acquires new concepts and conceptual relations about topics dealing with the dietary habits of animals, their classifications and habitats. The program is also able to answer an am...

To ensure safe flight under snowy conditions, aircraft manufacturers must demonstrate that each engine and its air inlet system can operate throughout the power range of (including idling) in both falling blowing snow conditions. This study is part an effort to develop models for accretion. The focus here on modeling snowflake transport by carrier airflow more specifically drag coefficient snow...

In vitro mass production of C. suaveolens (Lindl.) Hook, an endangered orchid with its snowy white flowers having horticultural potential was accomplished through immature seed culture, and subsequent plant regeneration. The developmental stage of the immature seeds and nutrient media significantly influenced the germination frequency. Seeds at 13 months after pollination cultured on 3% sucrose...

Seven to nine days after inoculation with a replicating antigen, Venezuelan encephalitis virus, hemagglutination-inhibiting antibodies were present in plasma of 18 to 20 black-crowned night herons (BCNH), 14 of 15 great egrets (ge) , and 7 of 7 snowy egrets (SE). 19S (immunoglobulin M) precedes 7S (immunoglobulin G) antibodies in all but one bird of six GE, six SE, and six BCNH. 19S antibodies ...

Thirteen species of helminth parasites were recovered from six species of charadriid shorebirds (Aves: Charadriiformes) from Belize: the ruddy turnstone, Arenaria interpres, the snowy plover, Charadrius alexandrinus, the semipalmated plover, C. semipalmatus, the killdeer, C. vociferus, the white-rumped sandpiper, Calidris fuscicollis, and the black-bellied plover, Pluvialis squatarola. Cestode ...
