This paper describes multitasking facilities of Ada in concurrent and real-time programming. Synchronization and process communication mechanisms are discussed in detail, also, a new mechanism to solve the scheduling problem is developed. In the concurrent programming aspect, a comparison is made between Ada's rendezvous and Pascal's Monitor concept. In the real-time programming aspect, the differences between the Ada multitasking and the traditional "cyclic executive approaches are contrasted and their associated costs/benefits analyzed.

Many Twain scholars believe that his skepticism was based on personal tragedies of later years. Others find skepticism in Twain's work as early as The Innocents Abroad. This study determines that Twain's atheism is evident in his earliest writings. Chapter One examines what critics have determined Twain's religious sense to be. These contentions are discussed in light of recent publications and older, often ignored, evidence of Twain' s atheism. Chapter Two is a biographical look at Twain's literary, family, and community influences, and at events in Twain's life to show that his religious antipathy began when he was quite young. Chapter Three examines Twain's early sketches and journalistic squibs to prove that his voice, storytelling techniques, subject matter, and antipathy towards the church and other institutions are clearly manifested in his early writings.

Previous research has shown that accountants may be inadequate moral reasoners. Concern over this trend caused the Treadway Commission (1987) and the Accounting Education Change Commission (1990) to call for greater integration of ethics into the student's training. Ponemon and Glazer (1990) found a difference in cognitive moral development (CMD) between accounting students at a public university and a private university with a liberal arts emphasis. This study expands Ponemon and Glazer's research by examining two liberal arts universities, one a private, secular institution and one a Catholic institution. The primary research question asks if Catholic university accounting students manifest greater CMD growth than secular university accounting students. Additionally, this study examines and compares the priority that accounting students from the different institutions place on ethical values versus economic values. It was expected that Catholic university accounting students would manifest both greater CMD growth and a greater concern for ethical values over economic values when compared with non-Catholic university accounting students. The study utilized a two-phase approach. In the first phase, an organizational study of two institutions was made to determine how each strives to integrate moral development into their accounting students' education. In the second phase, lower-division and senior …

The purpose of this paper is to illustrate the use of the computer in solving complex real time scheduling problems. This problem involves the airline industry and is concerned with the local scheduling of security personnel to the gate areas for outgoing flights from one terminal at Dallas-Fort Worth airport. The purpose of this type of program is to enhance personnel efficiency and management control over a large group of people while cutting the cost of lower management.

Ribavirin, a synthetic nucleoside, was found to inhibit the replication of Rous sarcoma viruses (RSV) and subsequent cell transformation in chick embryo fibroblasts (CEF). It also blocked the transformation of normal rat kidney (NRK) cells infected with temperature-sensitive mutants of RSV. The action of Ribavirin was found to be reversible as removal of the drug from the NRK cells reversed the effects on cell transformation. Ribavirin appears to have a static effect on cell growth of both NRK and CEF cells. In addition, guanosine, xanthosine and inosine altered the effect of Ribavirin on cell growth.

The Bill J. Priest Institute for Economic Development is an entity created in the Dallas County Community College District to serve the community in workforce and economic development. The history of the Priest Institute over the last ten years parallels and illustrates the commitment of community colleges nationally to workforce and economic development. The history also reflects similar goals and trends within the state of Texas and, particularly, in the city of Dallas. The Priest Institute is made up of three distinct entities. One entity is the Edmund J. Kahn Job Training Center; another is the Business and Professional Institute, which provides consulting and training services to business clients. The final service area is the complex made up of the regional North Texas Small Business Development Center and its several related local service operations. This study provides an analytical history of each of these components and the process by which they came together in a model facility in Dallas. This study also describes perceptions of persons within the Institute regarding its present mission and purposes and the efficacy of the current organizational structure both internally and within the district operation as an appropriate structure enabling the Institute to meet its …

The purpose of the present study was to begin development of a psychological profile for environmentally ill patients. Existing psychiatric labels are unable to encompass these patients. Test scores were drawn from a pool of 89 patients whose environmental exposures were verified by the presence of toxins in the blood serum. A Mental Status Exam, a Wechsler Adult Intelligence Scale-Revised screen, and the Profile of Mood States were administered. Results indicate a primary pattern which is significantly different from test norms consisting of fatigue, reduced mental functioning, and a lack of psychotic or personality disorder indicators. The reported symptoms of environmentally ill patients were objectively verified by current psychological test instruments. The need for a new diagnostic category for people who have been poisoned by environmental toxins is discussed.

The scientific subroutine package is one of the most important parts of the software for the scientific industry. By now, most big computers have scientific packages, but applying such a software package in microprocessors requires consideration of the microprocessor's facilities, such as limited main memory, slow execution time, and only a few small registers. In any scientific package, the trigonometric functions are the ones more widely used. This paper discusses a method for implementing several trigonometric function programs in a scientific package in microprocessors. These programs will contain routines for computing sin, cos, tan, and cot of any angle within the range of (-360°,+360°).

High Performance Liguid Chromatography was used to measure degradation of nucleotides in human cadavers for the purpose of prediction of post mortem interval. Endogenous nucleotides were extracted from integumentary tissue of six(6) human cadavers using six percent(6%) tricholoacetic acid. Linear regression statistical techniques were used to determine linearity of degradation of various nucleotide pools.

Twentieth-century science proves that heredity and environment function similarly in all named living species except one--Homo sapiens. Man alone, through his intellect, forms language and culture, thereby affecting his environment so that he participates in the process of his own creation. This participation so links humans that each man extends outside himself creating of the human race a single, whole fabric. C. P. Snow, aware of this communal reality, notes the present lack of communication between scientists and humanists. He contends that this lack, described as the two-cultures split, endangers both the practical survival of Western civilization and mankind's understanding of its own humanity. This study analyzes modern scientific reality and shows that Snow's articles, lectures, and novels articulate that reality and confirm the merit of Snow's observations.

This is a brief survey of some of the popular computer systems. As many features as possible have been covered in order to get an overview of the systems under consideration.
