Determination Of Protein Profile And Presence Of Antibodies In Llama Seminal Plasma (Llama Glama), Francisco Flores Lópes

Theses and Dissertations

Internationally, Bolivia has the largest llama population followed by Peru. This makes our country a power in this renewable resource for working and generating economic development. This is mainly because of the quality of llama meat, which has nutritional properties superior to other animal species. The development and research in our country of llamas is not very significant. But in other countries advanced studies have been done for years, specifically in the area of reproduction, which represents problems for intensive repopulation because of singular characteristics of semen and copulation. The present research work was done at the UAC in Tiahuanacu …

Application Of A Rational Model In Gis For Flood Risk Assessment In Accra, Ghana

Journal of Spatial Hydrology

Accra has been experiencing periodic flooding that affect properties and lives. The government seeing the dangers involved has commissioned institutions such as Ministry of Works and Housing, Town and Country Planning and City Engineers to identify flood risk zones and adapt measures that will help reduce flood damages. These institutions identify flood risk zones using conventional methods such as watermarks on buildings and reported cases in the news media. Works carried out by these agencies were not able to give details about potential areas that are likely to experience this extreme event. Hence there was the need to find a …

A Comprehensive Gis-Based Modeling Approach For Predicting Nutrient Loads In Watersheds

Journal of Spatial Hydrology

A comprehensive, GIS-based modeling approach was developed to enable accurate prediction of nutrient loads in watersheds throughout the state of Pennsylvania; particularly those watersheds for which stream monitoring data do not exist. This approach relies on the use of statewide GIS data sets for deriving reasonably good estimates for various critical model parameters that exhibit considerable spatial variability within the state. Data manipulation and subsequent simulation modeling is managed via an interface (called AVGWLF) between a popular desktop GIS software package (ArcView) and the Generalized Watershed Loading Function (GWLF) model. The modeling approach was tested in thirty-two (32) watersheds throughout …

Reliability Of Programmable Input/Output Pins In The Presence Of Configuration Upsets, Paul S. Graham, Nathaniel Rollins, Michael J. Wirthlin, Michael P. Caffrey

Faculty Publications

Sponsorship: Los Alamos National Laboratories (LA-UR-02-3163). Field programmable gate arrays (FPGAs) are an attractive alternative for space-based remote sensing applications. However, SRAM-based FPGAs are sensitive to radiation induced single-event upsets within the configuration memory. Such configuration upsets may change the logic, routing, and operating modes of a user FPGA design. Upsets within the configuration of an I/O block are especially troublesome as they may impact the operation of other system components. This paper will evaluate the operation of the I/O block within the Xilinx Virtex FPGA in the presence of configuration memory upsets and introduce techniques for detecting and repairing …

Surface Micromachined Force Gauges: Uncertainty And Reliability, Jonathan W. Wittwer, Troy Gomm, Larry L. Howell

Faculty Publications

Surface micromachining of micro-electro-mechanical systems (MEMS), like all other fabrication processes, has inherent variation that leads to uncertain material and dimensional parameters. By considering the effects of these variations during the design of micro force gauges, the gauge uncertainty and reliability can be estimated. Without means of calibrating micro gauges, these effects are often significant when compared to experimental repeatability. The general force gauge model described in this paper can be used to measure a wide range of forces, and simple design changes can lead to improved accuracy in measurement. A method of probabilistic design is described that is not …

Spectral Integration Of Microstructure And Design, Brent L. Adams, B. Henrie, M. Lyon, H. Garmestani, Surya R. Kalidindi

Faculty Publications

Support of the Army Research Office is greatly appreciated. Mechanical design can be conducted in a framework where consideration of microstructure as a continuous design variable is facilitated by the use of a Fourier space. Selection of the mechanical framework for the problem (e.g., mechanical constitutive model and homogenization relations) dictates the dimensionality of the pertinent microstructure representation. Microstructure is comprised of basic elements that belong to the local state space. Local state includes crystallographic phase and orientation, and other parameters such as composition. The local state space is transformed into an isomorphic set in Fourier space. The universe of …

A Categorial Grammar Fragment For Lushootseed, Deryle W. Lonsdale

Faculty Publications

This paper establishes a basic framework for a Categorial Grammar (CG) description ofLushootseed morpho syntax and semantics. After a brief review of English CG principles, a preliminary attempt is made to apply these fundamentals to Lushootseed free and bound morphemes. Several sample derivations are presented. including one rather complex syntactic ambigiuty previously noted in the literature with its alternative descriptions. Once the syntactic elements have been put in place a short overview is presented of how semantic interpretation can be established in tandem with syntactic composition principles. Finally, the implementation of this framework within the Attribute Logic Engine environment is …

Peppering Knowledge Sources With Salt: Boosting Conceptual Content For Ontology Generation, Deryle W. Lonsdale, Yihong Ding, David W. Embley, Alan Melby

Faculty Publications

This paper describes work done to explore the common ground between two different ongoing research projects: the standardization of lexical and terminological resources, and the use of conceptual ontologies for information extraction and data integration. Specifically, this paper explores improving the generation of extraction ontologies through use of a comprehensive terminology database that has been represented in a standardized format for easy tool-based implementation. We show how, via the successful integration of these two distinct efforts, it is possible to leverage large-scale terminological and conceptual information having relationship-rich semantic resources in order to reformulate, match, and merge retrieved information of …

Faculty Publications

Data collected by the C band ERS-2 wind scatterometer (EScat), the Ku band ADEOS-1 NASA scatterometer (NSCAT), and the Ku band SeaWinds on QuikScat (QSCAT) satellite instruments are used to illustrate spatiotemporal variability in snow accumulation on the Greenland ice sheet. Microwave radar backscatter images of Greenland are derived using the scatterometer image reconstruction (SIR) method at 3-day intervals over the periods 1991–1998 and 1996–1997 for EScat and NSCAT, respectively. The backscatter coefficient σ° normalized to 40° incidence, A, and gradient in backscatter, B, in the range 20°–60° are compared with historical snow accumulation data and recent measurements …

A Habitat Suitability Model For Pygmy Rabbits (Brachylagus Idahoensis) In Southeastern Idaho, Kate I. Gabler, Laura T. Heady, John W. Laundré

Western North American Naturalist

A habitat suitability model was developed for pygmy rabbit (Brachylagus idahoensis) habitat on the Idaho National Engineering and Environmental Laboratory (INEEL) in southeastern Idaho. Suitable pygmy rabbit areas were characterized by greater cover and density of total shrubs and big sagebrush (Artemisia tridentata), as well as greater forb cover. Soil texture also played an important role in distinguishing suitable pygmy rabbit areas from nonuse sites. Principal components analysis (PCA) of several vegetation variables and soil texture was used to develop a habitat suitability model for pygmy rabbit habitat. This model, which can be used to successfully …

Stacked Subwavelength Gratings As Circular Polarization Filters, Gregory P. Nordin, P. C. Deguzman

Faculty Publications

We have stacked subwavelength gratings (SWGs) on a single substrate to create a compact, integrated circular polarization filter. The SWGs consist of a wire grid polarizer and a broadband form-birefringent quarter-wave plate (QWP). Rigorous coupled-wave analysis was used to design the QWP for operation over the 3.5-5.0 m wavelength range. The fabricated silicon broadband QWP exhibited a phase retardance of 82-97° across this wavelength range. Two stacked structures are presented, each with a different wire grid polarizer fabricated on an organic planarization layer (SU-8) that is deposited on a QWP grating. Transmittance measurements of the first structure when illuminated with …

Ortho-Planar Linear-Motion Springs, John J. Parise, Larry L. Howell, Spencer P. Magleby

Faculty Publications

This paper presents an ortho-planar spring design that operates by raising or lowering its platform relative to the base with no rotation. The compact nature of the design, and its non-rotating motion, eliminates the problem of rotation against adjoining surfaces and is less sensitive to variation in assemblies than many current compact springs. Nomenclature is presented to identify different configurations, mathematical equations are provided that accurately model the force-defection relationships, and a pneumatic valve positioner application is demonstrated.

Using Ssm Proxies To Provide Efficient Multiple-Source Multicast Delivery, Daniel Zappala, Aaron Fabbri

Faculty Publications

We consider the possibility that single-source multicast (SSM) will become a universal multicast service, enabling large-scale distribution of content from a few well-known sources to a general audience. Operating under this assumption, we explore the problem of building the traditional IP model of any-source multicast on top of SSM. Toward this end, we design an SSM proxy service that allows any sender to efficiently deliver content to a multicast group. We demonstrate the performance improvements this service offers over standard SSM and describe extensions for access control, dynamic proxy discovery, and multicast proxy distribution.

Many Voices, One Umma: Sociopolitical Debate In The Muslim Community, James A. Toronto

BYU Studies

As a religion expands beyond its original setting, it encounters new historical, economic, social, and geopolitical forces. The resulting clash between sacred truth and secular reality created ideological tensions within a religious community that lead its followers to engage in a process of dialogue, reform, and reconciliation. This process of dialectical exchange occurs both between members of the community and between the community and outside forces. Often it gives rise to traumatic, even violent, conflict and frequently leads to schisms and the establishment of break-away religious movements. The history of religion provides abundant evidence that the ability of a nascent …

Characterization Of Two-Dimensional Finite-Aperture Wire Grid Polarizers By A Spectral-Domain Technique, Michael A. Jensen, Gregory P. Nordin

Faculty Publications

We investigate the transmission characteristics of perfectly conducting two-dimensional wire grid polarizers fabricated in finite and infinite apertures using a rigorous spectral-domain mode-matching method. Specifically, the transmission coefficient for both transverse-electric and transverse-magnetic polarizations, extinction ratio, and diffraction pattern are characterized for a wide variety of geometric and material parameters including aperture dimension, conducting wire fill factor, wire spacing, polarizer thickness, material dielectric constants, and incident wave arrival angle. The results indicate that the transmission behavior is largely insensitive to aperture dimension.

Institutional Alternatives For The Promotion Of Microfinance: Self-Help Groups In India, P. Satish

Journal of Microfinance / ESR Review

Microfinance is now an accepted institutional framework for taking financial services to the poor. It is but natural that microfinance should have had tremendous growth in India--the home to the largest concentration of poor. In India the microfinance technology that had a relatively higher growth in the last decade is the self-help group (SHG). This lays stress on thrift as well as credit and also on the linkage between informal groups and formal financial institutions. An important sine qua non in this technology is the institution that promotes the SHGs. In India, SHGs have been promoted by nongovernmental organizations (NGOs), …

Rethinking The Approach To The Microenterprise Sector In Latin America: An Intergrating Framework, Jaime Ortiz

Journal of Microfinance / ESR Review

Unavoidable macroeconomic adjustment policies have exacerbated social inequalities in Latin America. As a result, electoral platforms have identified microenterprises as an alternative economic activity to help alleviate poverty. Pursuing an efficient microentrepreneurial base requires from governments a comprehensive package of both financing and training strategies. Conversely, microentrepreneurs require a better understanding of their activity in order to set forward arguments that will allow them to enhance their management practices. Government policies towards the microenterprise sector should create favorable conditions conducive to the establishment and operation of financial institutions as well as specialized nongovernmental organizations providing training and consulting. Within that …
