While the Ada community has seen and embraced the development of Ada 95 1], with its enhanced object oriented features and various annexes, much of the rest of the commercial world continues to ignore Ada as a viable tool for software system building. EEorts have been ongoing for some time to provide rationale showing the superiority of Ada 95 over other choices such as C and C++, but with limi...

Genetic defects in the adenosine deaminase (ADA) gene are among the most common causes for severe combined immunodeficiency (SCID). ADA-SCID patients suffer from lymphopenia, severely impaired cellular and humoral immunity, failure to thrive, and recurrent infections. Currently available therapeutic options for this otherwise fatal disorder include bone marrow transplantation (BMT), enzyme repl...

MaRTE OS (Minimal Real-Time Operating System for Embedded Applications) is a real-time kernel for embedded applications that follows the Minimal Real-Time POSIX.13 subset, providing both the C and Ada language POSIX interfaces. It allows cross-development of Ada and C real-time applications. Mixed Ada-C applications can also be developed, with a globally consistent scheduling of Ada tasks and C...

In 1983, the U.S. Department of Defense (DoD) established a policy requiring the use of Ada for the development of all new DoD mission-critical computer applications. A multi-industry field study was conducted with seven business units from DoD contractors that have made decisions about the adoption and use of Ada. This report examines the extent to which the Ada adoption behavior of these cont...

Ten patients with adenosine deaminase deficiency (ADA-) have been enrolled in gene therapy clinical trials since the first patient was treated in September 1990. We describe a Japanese ADA- severe combined immune deficiency (SCID) patient who has received periodic infusions of genetically modified autologous T lymphocytes transduced with the human ADA cDNA containing retroviral vector LASN. The...

Lanthanide complexes with a series of hexapeptides-incorporating two unnatural chelating amino acids with aminodiacetate groups, Ada(1) and Ada(2)-have been examined in terms of their speciation, structure, stability and luminescence properties. Whereas Ada(2) acts as a tridentate donor in all cases, Ada(1) may act as a tetradentate donor thanks to the coordination of the amide carbonyl functio...

Human adenosine deaminase (ADA; EC 3.5.4.4) consists of three isoenzymes: ADA1, ADA1+CP, and ADA2. We developed an electrophoretic technique to distinguish between these three isoenzymes. The isoenzyme pattern was studied in tissue and cell homogenates, as well as in serum from normal subjects and from patients with increased serum ADA who had either hepatitis, infectious mononucleosis, tubercu...

The architecture of a system expresses the structural aspects of the system | the modules, the control structure, communication patterns , sharing of data and composition of modules. The architecture of a complex software system is a signiicant issue in the proper design, analysis and possibility of reuse of the software system. This paper describes how the architecture of an Ada program may be...
