This thesis focuses upon the practice and realities of 19th century rural medical practitioners located throughout segments of southwestern Virginia. The study particularly examines the career of Montgomery County physician Robert T. Ellett, M.D. Despite opening a practice located far from his family home, Ellett's medical career gradually thrived despite operating within an arduous social and geographic environment. Initially Ellett's entrance into Montgomery County society depended solely upon his elite stature and adherence to their established "common interests." However, as time passed his identity became increasingly multidimensional. Ellett carefully crafted fruitful doctor/patient relationships by cautiously negotiating the domestic sphere. Patients and family members alike thought of Ellett as a healer and a "man of medicine." Meanwhile, Ellett sustained the financial growth needed to support his large family by holding numerous local patronage positions. Ironically, while Ellett's domestic relationships constructed his professional identity, that role was preserved by constantly manipulating positions gained through that trust. Therefore, country physicians depended upon much more than personal character in building their practices. Instead, successful practitioners in similar social environments achieved stability by balancing a multidimensional identity that ultimately subscribed to both local and personal interests. / Master of Arts

The Wilderness Road, starting in Big Lick (Roanoke today) was a primary route over the Allegheny mountains for travelers migrating to the Kentucky frontier. Ordinaries and taverns (referred to as public houses) were known to offer food and lodgings to travelers in the state capital city of Richmond, but little is known about what, if any, accommodations were available to these settlers headed westward through southwest Virginia. With the first stops along the Wilderness Road being in Montgomery County, this study sought to determine if public houses existed in this county between the years 1773-1823, and if so, where were they located and who operated them. Further, what was the typical design or plan of public houses and how would they have been furnished. What comparisons could be made between public houses in Richmond and on in southwest Virginia. County court records, including wills, appraisals, licensing records, and court order books revealed that public houses not only existed, but also there were often as many as 5 or 6 operating at one. A license had to be purchased each year from the court and names of proprietors were recorded. These listings also helped to identify structures standing today that once served as a public house. On site observations along with WPA (Work Projects Administration) reports and the Virginia Department of Historic Resources surveys documentation of historic houses in the county offered notable similarities in design and plan among five former houses selected for this study. Wills and appraisals provided some clues about furnishings. The result of this study adds an important chapter to the story of public houses in early Virginia history. / Master of Science

Jane Maria Eliza McManus, born near Troy, New York, educated at Emma Willard's Troy Female Seminary, promoted the American maritime frontier and wrote on Mexican, Central American, and Caribbean affairs. Called a "terror with her pen," under the pen name of Cora Montgomery, she published 100 columns in 6 newspapers, 20 journal articles and book reviews, 15 books and pamphlets, and edited 5 newspapers and journals between 1839 and 1878.

Nowadays, Internet plays an indispensable role in human lives. People use Internet to search information, transmit data, download ?le, and so on. The data transformed to the composed digital signal by ¡¦0¡¦ and ¡¦1¡¦ are transmitted on Internet . However, Internet is open and unreliable, data may be stolen from the other people if they are not encrypted. In order to ensure the security and secret of data, the cryptosystem is very important. RSA is a famous public-key cryptosystem, and it has easy concept and high security. It needs a lot of modular exponentiations while encryption or decryption. The key length of RSA is always larger than 1024 bits to ensure the high security. In order to achieve real time transmission, we have to speed up the RSA cryptosystem. Therefore, it must be implemented on hardware. In RSA cryptosystem, modular exponentiation is the only operation. Modular exponentiation is based on modular multiplications. Montgomery¡¦s Algorithm used simple additions and shifts to implement the complex modular multiplication. Because the key length is usually larger than 1024 bits, some signals have a lot of fan-outs in hardware architecture. Therefore, the signals have to connect buffers to achieve enough driving ability. But, it may lead to longer delay time and more power consumption. So, Tenca et al. proposed a Multiple Word Montgomery Algorithm to improve the problem of fan-out. Recently, Huang et al. proposed an algorithm which can reduce data dependency of Tenca¡¦s algorithm. This research is based on the architecture of Huang¡¦s algorithm and detects the redundant operations. Then, we block the unnecessary signals to reduce the switch activities. Besides, we use low power shift register to reduce the power consumption of shift register. Experimental results show that our design is useful on decreasing power consumption.

The research hypothesis of this study states that the springhouses of Montgomery County, Virginia, are part of an established, regionally specific, rural vernacular building tradition. Over the one-hundred and fifty-year period examined for this survey, the form and design of springhouses remained consistent, but the size, number, construction materials, and functions of springhouses changed, in response to economic, social, and technological developments. The purpose of this study was two-fold: first, to document existing springhouses in Montgomery County, Virginia, using photographs and an evaluation form; and secondly, to provide analysis and interpretation of regional springhouse design, construction, and use, based on fieldwork. While springhouses appear to be relatively few in number in comparison with other farm structures, such as barns, many were adapted and maintained for decades, and some are still being used today. Their continued survival, however, may depend upon sympathetic property owners who recognize the significance of the springhouse to the rural landscape. This work will comment on the physical and material contexts of the springhouse as a building type; describe springhouse characteristics; and provide a catalog of fifty existing springhouses in Montgomery County, Virginia. / Master of Science

Shiitake growers in Virginia are experiencing considerable diminution of the fruiting life of oak logs, due primarily to Ascomycetous, competing, wood-rotting, contaminating "weed fungi" that either invade the logs after trees are felled or are present in tree tissues before felling. We surveyed several shiitake farms, and, although the fungal flora differed among them, the predominant colonizing fungi were identified as Graphostroma platystoma (also identified as Diatrype stygma), Eutypa spinosa and Slereum aff. complicatum. Other less frequently observed fungi were Stereum ostrea, Schizophyllum commune, Hymenochaete sp., Poria sp., Hypoxylon atropunctatum and Hypoxylon punctulatum. Site and means of invasion (colonization) of these "weed fungi" were studied by monitoring endophytic fungal populations in stressed and non-stressed oak trees in the Jefferson National Forest Montgomery County, Virginia. Twenty-six samples from Poverty Creek (non-stressed) and 23 from Brush Mountain (stressed) were studied. Fifty percent of the samples from the non-stressed were sterile, 23% yielded Paecilomyces variota., and 27% were colonized by other fungi. On the other hand, 100% of the samples from stressed trees (Brush Mountain) were colonized by fungi; 74% yielded P. variotii and 26% by other fungi. Thirty samples from a pin oak (Quercus paluslris) plot at Virginia Tech (non-stressed) were 74% sterile, 16% colonized by an unidentified yeast, and 10% colonized by other unknown fungi. / Master of Science
