In this model, information system is regarded as controlled plant, user's preference about attributes is regarded as control objective, and the iterative algorithm designing process is regarded as control law designing.
Past year medicinal plant users were older than non-users (p = .001), but gender was not a factor in usage (p = .164).164
The objective of this study is to compare medicinal plant use between two different ethnic college populations and explore differences between student medicinal plant users and non-users for comparison with previous research.
Context-specific knowledge about soil variation, temperature, water, characteristics of local plants, and seasonal conditions accumulated over generations enables medicinal plant users in the Afghan and Tajik Pamirs to sustain dynamic relationships within their habitat (Kassam 2009a).
While Native American student medicinal plant users reported significantly higher rates of commercial tobacco use, lower self-assessment of health, and less use of prescription medicine than non-Native users, no significant differences in prevalence of medicinal plant use were found between University student populations.
Further, qualitative research, including interviews and case studies, of different cross-sections of medicinal plant users can reveal details that this survey did not capture, thereby adding explanatory depth to the results reported here and in other surveys of CAM use.
Excessive sediment in surface water causes problems for aquatic life by increasing turbidity and destroying habitat; increases treatment costs for drinking water plants, industrial users, and some agricultural users; and reduces recreational opportunities (EPA 1996; Vellidis and others 2003b).
Electric power transmitted over large distances from generating plants to users involves voltages that vary sinusoidally in time, at a frequency of 60 hertz (Hz) in the United States and Canada and 50 hertz in Europe.
Last July, during the inaugural round of the online cybersecurity simulation game NetWars, 75 contestants vied to hack into and control the game's 12 servers, planting their user names on the conquered computers to declare their territory.
