Hemagglutination and fluorescent antibody (FA) are compared for the direct detection of virus devoid of host cells. A determination was made of the minimal number of tissue plaque-forming units of Venezuelan equine encephalomyelitis virus that could be detected by the hemagglutination technique. Similar concentrations of the virus in bovine albumin borate saline, Brain Heart Infusion broth (Dif...

The Scottish island of Islay hosts 45 000 barnacle geese Branta leucopsis (56% of the Greenland barnacle goose population, plus those passing through on migration), 5000 Greenland white-fronted geese Anser albifrons flavirostris (up to 30% of the world population) and 2500 greylag geese Anser anser, most of which feed on 9000 ha of grassland. The financial impacts of estimated agricultural dama...

A 3D Rapid, GlObally Optimal Surface Estimation (R-GOOSE) algorithm for fat-water decomposition in MRI is proposed. The fat-water separation is formulated as an optimization problem with data consistency and eld-map smoothness penalty. The data consistency only contains exact minimizers from the fully discretized eld-map value volume. The proposed method employs a connectivity-reduced graph con...

The cross-sectional echocardiographic demonstration of the "goose-neck" deformity is described in four patients with endocardial cushion defect. The diagnosis was confirmed in each patient by left ventricular angiocardiogram. The subxiphoid approach of cross-sectional echocardiography in diastole allowed visualization of an elongated, narrowed, and somewhat horizontally inclined configuration o...

While enjoying music and other works of art, people sometimes experience "chills," a strong emotional response characterized by a sensation of goose bumps or shivers. Such experiences differ from having goose bumps as a defense response or from shivering in reaction to cold temperatures. The current paper presents the phenomenon of music-induced chills and reviews the chill-related emotional re...

OBJECTIVE The objective of the present study was to investigate the histological structure of goose pancreatic ducts. DESIGN Tissue samples from the lobes and ducts of the pancreas were dissected under deep ether anesthesia. INTERVENTIONS Sections were stained using Crossmon's connective tissue method for general observations and Gomori's method for pancreatic islet cells. RESULTS The gla...

This paper describes the object-oriented design and implementation of an extensible schema manager for object-oriented databases. In order to achieve extensibility, we have adopted an open class hierarch y approach using an ob ject-oriented implementation where an object-oriented database maintains its implementation classes as user-defined classes. A Graphical interface for an Object-Qriented ...

The effects of grazing winter wheat (Triticum aestivum) by Canada geese (Branta canadensis) was assessed in 3 fields during 2 years of experimentation at the Wye Research and Education Center, Queenstown, Maryland. Randomly placed wire enclosures prevented goose grazing on 11.1 m sq. control plots. Grazed plots were marked in each field soon after the geese migrated in March. Grazed plots had c...
