The axisymmetric damage model (ADM) is one of four micromechanical stress field models developed and maintained by N. J. Pagano's group at the AFRL Materials Directorate, Wright-Patterson AFB. These models serve to establish rigorous field theories to compute accurate stresses and energy release rates for fracture mechanics problems in composite bodies. In turn, these solutions, coupled with ex...

Received 18 November 1997; accepted 27 June 1998) The procedure for phenotyping of most genetic variants in cow milk was optimised for iso-electric focusing (IEF) of camel milk proteins and milk from individual camels of different breeds was screened. The caseins obtained from IEF bands were also investigated by Nterminal sequencing. Camel milk casein was separated at different pH and the prote...

The types and extent of regional phonetic and phonological variation in African American Vernacular English (AAVE), have, until quite recently, remained largely unknown and understudied, despite sociolinguists’ detailed knowledge of AAVE morphosyntax (Bailey & Thomas 1998). However, with the publication of the papers collected in Thomas & Yeager-Dror (in press), and a series of other recent pub...

The 195- and 214-amino-acid (aa) forms of the delta protein (deltaAg-S and deltaAg-L, respectively) of hepatitis delta virus (HDV) differ only in the 19-aa C-terminal extension unique to deltaAg-L. deltaAg-S is needed for genome replication, while deltaAg-L is needed for particle assembly. These proteins share a region at aa 12 to 60, which mediates protein-protein interactions essential for HD...

OBJECTIVE Appendicitis is the most common non-traumatic surgical abdominal disorder in children aged 2-years or older. It is generally believed that delay in diagnosis and surgery of acute appendicitis is associated with a more advanced stage of disease and a higher morbidity. The aim of this retrospective study was to document the clinical features of acute appendicitis (AA), and to describe t...

Smoking is the leading cause of preventable death and disability in the United States, and African Americans (AAs) bear a disproportionate burden of the health consequences of smoking.1 Compared with white smokers, AA smokers have a higher incidence and death rate for cancers of the oral cavity and pharynx, esophagus, cervix, larynx, stomach, pancreas, and lung.2,3 The death rate from cerebrova...
