Religion And Semiosphere: From Religious To The Secular And Beyond, Rajka Rush

Dissertations

Religion is a system of structural ideas that involve the natural ability of the mind to engage itself into the process of unlimited semiosis which can be defined as an existential openness of one's consciousness to the universe as a system. This primary religious consciousness becomes limited by language, symbolic, and cultural constraints. The religious semiotic space is a sub-cultural system open to culturally and cross-culturally encoded idioms and concepts. These cultural potentials are interpreted and settled by the religious exegesis expressed in the behavioral patterns of the symbolic actions that reflect a specific worldview of the closed community controlled …

Mathematical Treatment For Solition-Soliton Interactions In Mono-Mode Optical Fiber, S.Y Al-Dabagh, A.S. Al-Ethawi, K.A Al-Namee

Baghdad Science Journal

Mutual interaction of two solitons with equal amplitude ratio (K = 1) of initial pulse separation (tau_{0} = 3.5pw) propagate in mono-mode optical fiber (30,90)km is studied analytically. The examination of propagation of two solitons with unequal amplitude ratio( K = 1, 1 ) initially separated by (tau_{0} = 3.5pw) is studied also. Results show that solitons of equal amplitude coalesce into one pulse at Psi = pi and eventually separate to the initial state at y = 2pi and so on. Launching solitons with unequal amplitude i.e (K = 1.1) is the simplest way to reduce soliton interaction in …

Development Of Methods For The Study Of Phosphoproteins, Zhaoyuan Chen

Theses and Dissertations

Characterization of phosphoproteins-including detection, identification of phosphoproteins and identification of phosphorylation sites-is mostly done with radiolabeling and proteomic techniques. Three main topics related to phosphoprotein characterization are included in this dissertation. First, large-scale characterization of the CHO (Chinese hamster ovary) cell phosphoproteome was done using two dimensional gel electrophoresis (2DE) separation, visualization of phosphoproteins by radiolabeling or a phosphoprotein specific dye, followed by MALDI-TOF identification. Because radiolabeling of phosphoproteins is very sensitive and straightforward to quantify, such analysis can give a clear picture of the relative phosphosphorylation of proteins present in a sample. But there are also limitations to this …

The Relationship Between The Minimal Rank Of A Tree And The Rank-Spreads Of The Vertices And Edges, John Henry Sinkovic

Theses and Dissertations

Let F be a field, G = (V,E) be an undirected graph on n vertices, and let S(F,G) be the set of all symmetric n × n matrices whose nonzero off-diagonal entries occur in exactly the positions corresponding to the edges of G. Let mr(F,G)be the minimum rank over all matrices in S(F,G). We give a field independent proof of a well-known result that for a tree the sum of its path cover number and minimal rank is equal to the number of vertices in the tree. The rank-spread of a vertex v of G is the difference between the …

Analysis Of Nmr Spectra Using Digital Signal Processing Techniques., Jason Aaron Gearheart

Electronic Theses and Dissertations

Since its development, nuclear magnetic resonance (NMR) has become one of the primary methods of chemists for structure elucidation, which is the determination of a compound's molecular structure. Current software packages enable scientists to visualize the raw data produced by the spectrometer so that they can manually determine a compound's component parts. This is accomplished by manually comparing the spectrum of the mixture with various reference materials believed to be present. But these software packages can be expanded to do even more. It is the purpose of this thesis to provide an automated analysis package capable of analyzing a mixture …

Nesting Success Of Grassland And Savanna Birds On Reclaimed Surface Coal Mines Of The Midwestern United States, Edward W. Galligan, Travis L. Devault, Steven L. Lima

United States Department of Agriculture Wildlife Services: Staff Publications

Reclaimed surface coal mines in southwestern Indiana support many grassland and shrub/ savanna bird species of conservation concern. We examined the nesting success of birds on these reclaimed mines to assess whether such ‘‘unnatural’’ places represent productive breeding habitats for such species. We established eight study sites on two large, grassland-dominated mines in southwestern Indiana and classified them into three categories (open grassland, shrub/savanna, and a mixture of grassland and shrub/savanna) based on broad vegetation and landscape characteristics. During the 1999 and 2000 breeding seasons, we found and monitored 911 nests of 31 species. Daily nest survival for the most …

Sexual Interactions: Why We Should Talk About Sex In Hci, Johanna Brewer, Joseph Jofish Kaye, Amanda Williams, Susan Wyche

Computer Science: Faculty Publications

Within the CHI community there is growing interest in moving beyond cognition and expanding into the social, emotional, and bodily aspects of the human-computer experience. Sex lies at the intersection of these concerns, and indeed outside of HCI, has become a central topic for anthropology, behavioral sciences, and other areas of intellectual inquiry. Examining sex and themes related to it has benefited these disciplines and we intend to understand how it can contribute to HCI. There is a tendency to desexualize technology, despite the presence of sex and sexuality in a variety of interactions, including the use of the internet …

Guideline Institutionalization: The Role Of Merger Guidelines In Antitrust Discourse, Hillary Greene

William & Mary Law Review

With the growth of the administrative state, agency-promulgated enforcement policy statements, typically referred to as guidelines, have become ubiquitous in the U.S. federal system. Yet, the actual usage and impact of such guidelines is poorly understood. Often the issuing agencies declare the guidelines to be nonbinding, even for themselves. Notwithstanding this disclaimer, the government, private parties, and even the courts frequently rely on the guidelines in a precedent-like manner. In this Article, Professor Greene examines the evolution of one system of enforcement policy guidelines-the U.S. federal antitrust merger guidelines--and finds that these guidelines have acted as a stealth force on …

Seasonal Dietary Composition Of The Eastern Coyote (Canis Latrans) On The Berry College Campus In Northwestern Georgia, Kathleen Melissa Owens

Masters Theses and Doctoral Dissertations

Coyotes (Canis latrans) have progressively colonized eastern North America following wolf extirpation and the clearing of forested landscapes. The coyote has expanded its geographic range into Georgia during the past 50 years, and its impact as the top predator is potentially influencing community dynamics via competition and/or predation. Few studies have examined coyote food habits in the southeastern United States. Our objective was to determine prey items consumed by free-ranging coyotes living on Berry College lands in northwestern Georgia. One hundred and twenty-seven coyote scats were collected from May 2005 through August 2006 along seven major service roads that transected …
