Prototype of and ISU Farm Disinfection System for Use in Emergency Disease Outbreak
Get PDFAs the nation’s largest pork-producing state, Iowa has the upmost priority to protect its swine population from ailments, including biosecurity hazards such as swine disease. This is an essential issue for swine farmers across the state and worldwide need to have the ability to be prepared for. This project provides a design and list of materials for a system that removes organic material and disinfects both large machinery and small items efficiently, with a budget under $1500.
This design also utilizes a materials that can be accessed within a half hour drive of even the most remote Iowan farms, along with nationwide vendors
Design and Testing of a Cleaning and Disinfection System for Farm Equipment and Vehicles at Livestock Farms
Get PDFDuring a Foreign Animal Disease (FAD) outbreak, it is critical that people, equipment, and vehicles do not inadvertently move the disease-causing agent between premises (i.e., locations where animals are housed or otherwise handled). To prevent this potential transmission, a cleaning and disinfection (C&D) station must be established at the clean/dirty line on infected premises, and everything going on or off the premises pass through it. Without this critical precaution, more viruses may remain in the environment and cause potential infection of other premises and herds; thus, making FAD containment a challenge
Low Cost Method of Determining Grain Moisture for Small Holder Farmers
No full textSmall holder farmers in developing countries must store the grain they produce. Significant postharvest losses due to spoilage occur when grain is stored at a moisture content that is too high. Additionally, spoilage organisms create mycotoxins such as aflatoxin which is extremely detrimental to human health, especially children and pregnant women. Unfortunately, safe storage moisture levels cannot be determined by touch, smell or taste. It must be measured. Current moisture meter technology is well developed and accurate, but unaffordable for small holder farmers. This research replicates research previously done to measure moisture content using low-cost ($2) hygrometers - devices that measure temperature and relative humidity within the grain storage, the results of which can then be used with to predict moisture content. The project will validate the previous work and give practical experience so that ISU personnel can implement this low-cost technology in post-harvest loss reduction programs in Uganda and Ghan

History, identity, and the marginalized: an analysis of selected works by Han Shaogong and Su Tong
No full textSince Deng Xiaoping's liberalization of art and literature in 1977, literature in the People’s Republic of China has shown rapid development. While there are indisputably many sides to the "new" fiction of the Post-Mao era (1977 to present), the substance of the change can be summarized by saying that such works reflect an overall "return of the individual" to modern Chinese fiction, in terms of characterization, authorial style, and personal vision. This thesis examines the return of the individual from the specific angle of marginalized character and motif, since they are frequently used by contemporary writers to express an individual and often subversive perspective in fiction.
The contemporary writers Han Shaogong and Su Tong both make use of marginalized character types and marginalized motifs in some of their key works. In the four texts presented here, "Ba, ba, ba" and "Three Women" by Han Shaogong, and "1934Escapes" and Rice by Su Tong, marginalized character and motif are used to explore and articulate authorial vision of history and identity in China. Each author defines their marginalized characters differently, yet there are basic similarities. Central characters in the four works are characterized by their social marginalization; all refer to aspects of human nature in general, and to the "Chinese nature" or cultural character in particular. Similarly, marginalized motif in each work underscores an alternative viewpoint. Regional discourse, myth, superstition, fallible narrators, and images of ostracism and alienation posit a challenge to the dominant ideologies and literary conventions of the last forty years of mainland Chinese literature. This analysis of the techniques of characterization, narration and imagery, illustrate show marginalized character and motif are defined in each work and how they are used to underscore theme and meaning. Despite the continued obsession with China, both authors manage to convey their emphasis on history and identity with a covert cultural exploration. Ultimately, their work is ordered around aspects of human response and the human condition. They are not seeking to provide answers to the question of whether China, but rather to explore the individual's place in history in human terms.Arts, Faculty ofAsian Studies, Department ofGraduat
