Space Studies Thesis Defense

â€œClosed Ecological Systems Functional Stability Limits and Human Control Algorithms'
(Grand Forks, North Dakota): UND Space Studies' Master's student, Yevhen Holubynak, will defend his thesis on Monday, July 14 at 2:00 p.m. in Ryan Hall, Room 111. Holubynak's presentation, entitled, Closed Ecological Systems Functional Stability Limits and Human Control Algorithms' is free and open to faculty, staff and students.
This work (summarizing the results of experimentation with Closed Ecological System BIOS-3, Krasnoyarsk, and Russian Siberia in 1989-1998) is an attempt to analyze the process of plant biomass incineration as a source of carbon dioxide for plant photosynthesis and growth and its effects on closed system stability. It is common knowledge that incineration of phytomass supplies into the atmosphere of a Closed Ecological System (CES) not carbon dioxide only, but also gaseous toxic agents inhibiting photosynthetic processes. Mathematical modeling has demonstrated that when the limit value of intensity of production processes and matter turnover specific for every closed ecosystem is exceeded the gaseous toxic agents destroy the system. This value is proportional to CES buffer absorption capacity and is non-linearly dependent on the tolerance of the plant component to the impact of flue gases. Ratios have been derived by assigned intensity of matter turnover to evaluate buffer absorption capacities required for stable operation of CES.
About Space Studies: The Department of Space Studies offers a program leading to a Master of Science degree. This interdisciplinary program studies the conditions and implications of humankindï¿½s entry into space: including the political, legal, technical, scientific, economic, and historical impacts on a national and international level. Designed to prepare the student for positions in the commercial and governmental sectors of the rapidly growing field of space exploration and development, the Space Studies M.S. is offered on campus and over the Internet. The Department of Space Studies is consistently innovative in the delivery of education services, and is now planning for the creation of a Ph.D. program offered on campus and at a distance. Students with a variety of professional backgrounds from all over the world participate in our program.
