El distrito de San Pedro de Putina Punku, localizado en la zona de amortiguamiento del Parque Nacional Bahuaja Sonene, se caracteriza por la configuración de dos paisajes superpuestos: paisaje agrícola y paisaje natural, convirtiéndose en una localidad de gran biodiversidad ecológica y cultural. Sin embargo, el principal medio de subsistencia obliga a los pobladores a incurrir en sistemas agrícolas que afectan al medio natural en el que habitan. Por ello, el proyecto busca consolidar el paisaje cultural mediante la articulación de una red de caminos que permita controlar la expansión agrícola, vincular a los usuarios con su medio y potenciar otro medio económico alterno, a través del turismo sostenible Se toma en consideración la cosmovisión ancestral de los pobladores, basado en la técnica aymara de complementariedad ecológica, en la que se contempla al mundo como un todo integrado, permitiendo una reciprocidad entre el habitante y su entorno. De esta manera, “el camino” toma el papel principal, como medio para iniciar un proceso de restauración y revaloración del paisaje dual agrícola-natural. El programa propuesto complementa las actividades económicas potenciales (agricultura y turismo); con ello, los cultivos tradicionales de café adicionan al turismo sostenible como activador y generador de ingresos alternos a las economías locales y al Área Natural Protegida. El proyecto busca demostrar que el camino es el elemento principal de la red que puede restaurar y articular el territorio dañado, permitiendo la armonía entre ambos paisajes.

Throughout the history of the Annular Core Research Reactor (ACRR), Transient Rod (TR) A has experienced an increased rate of failure versus the other two TRs (B and C). Either by pneumatic force or electric motor, the transient rods remove the poison rods from the ACRR core allowing for the irradiation of experiments. In order to develop causes for why TR A is failing (rod break) more often, a better understanding of the whole TR system and its components is needed. This study aims to provide a foundational understanding of how the TR pneumatic system affects the motion of the TRs and the resulting effects that the TR motion has on the neutronics of the ACRR. Transient rod motion profiles have been generated using both experimentally-obtained pressure data and by thermodynamic theory, and input into Razorback, a SNL-developed point kinetics and thermal hydraulics code, to determine the effects that TR timing and pneumatic pressure have on reactivity addition and reactivity feedback. From this study, accurate and precise TR motion profiles have been developed, along with an increased understanding of the pulse timing sequence. With this information, a safety limit within the ACRR was verified for different TR travel lengths and pneumatic system pressures. In addition, longer reactivity addition times have been correlated to cause larger amounts of reactivity feedback. The added clarity on TR motion and timing from this study will pave the way for further study to determine the cause for the increased failure rate of TR A.

En la provincia de Sandia los productores agropecuarios de papayita andina trasladan la producción hasta Puno, Lima o Arequipa. En el transporte, pueden llegar a perder el 50% de producción. La papayita andina es una fruta que contiene propiedades nutricionales y medicinales, por lo que, es atractivo para el consumidor actual, más preocupado por la salud, no obstante, esta fruta tiene una vida útil de 12 días, lo que limita su exportación. Es por lo que, con este proyecto se desea atender ambas problemáticas, por un lado, asesorar al productor en el proceso productivo para obtener papayita andina de calidad, comprar la producción para reducir la merma del traslado. Y, además, promover la actividad industrial dentro de Sandia, al fomentar mayores puestos de trabajo, generar más ingresos para el productor agrícola al no tener que asumir costos de traslado y mermas. De igual modo, se contribuye con la exportación de productos de calidad que mantiene un buen sabor y conserva propiedades nutricionales y medicinales. Para validar la viabilidad del proyecto se entrevistó y encuestó a los productores agrícolas y a empresarios chilenos que se dedican a la importación y comercialización de productos agrícolas. Se obtuvo que, el 95% de los agricultores estaba dispuesto a vender la totalidad de la producción dentro de Sandia y el 100% mostró interés en: recibir asesoría y acompañamiento en el proceso productivo, registrar información de su cultivo y, formar parte de este modelo de negocio. Mientras que, el 66.7% de los empresarios chilenos si desea importar la papayita andina concentrada y esterilizada y comercializarla en dentro de Chile, mientras que el 100% considera que este producto tiene potenciales consumidores en el país del Sur. Para ejecutar este proyecto se necesita una inversión inicial de $415,522, que se respalda con el 60% por aporte de accionistas y el 40% con préstamo a largo plazo. El VAN del negocio es de $1’534,073 y la TIR es de 116%. De igual modo, este modelo contribuye con la ODS diez y dos, con lo que, se obtuvo un VAN Social de $3,629,504. / In the province of Sandia, Andean papaya farmers transport their production to Puno, Lima, or Arequipa. During transport, they can lose up to 50% of their production. The “papayita andina” is a fruit that contains nutritional and medicinal properties, making it attractive to today's health-conscious consumer; however, this fruit has a shelf life of 12 days, which limits its exportability. This is why this project aims to address both problems, on the one hand, to advise the producer in the production process to obtain quality “papayita andina”, buy the production to reduce the loss of the transfer. On the other hand, to promote industrial activity in Sandia by creating more jobs and generating more income for the agricultural producer by not having to bear the costs of transportation and wastage. Likewise, it contributes to the export of quality products that maintain a good taste and preserve nutritional and medicinal properties. To validate the feasibility of the project, we interviewed and surveyed agricultural producers and Chilean businessmen involved in the import and marketing of agricultural products. It was found that 95% of the farmers were willing to sell their entire production within Sandia and 100% showed interest in: receiving advice and accompaniment in the production process, recording information on their crop, and being part of this business model. Meanwhile, 66.7% of the Chilean entrepreneurs would like to import the concentrated and sterilized “papayita andina” and market it in Chile, while 100% consider that this product has potential consumers in the southern country. To execute this project, an initial investment of $415,522 is required, which is backed by 60% in shareholder contributions and 40% with a long-term loan. The NPV of the business is $1'534,073 and the IRR is 116%. Likewise, this model contributes to SDO ten and two, resulting in a Social NPV of $3,629,504.

The objective of this research was to evaluate the capabilities of ALEGRA, a Sandia National Labs hydrocode, and Forge3, a Transvalor S.A. product, to accurately model the Friction Stir Welding Process. ALEGRA and Forge3 are discussed in light of the inherent challenges of modeling Friction Stir Welding, and a rotational boundary condition is added to ALEGRA. Results are presented from Friction Stir Welding modeling outputs from both ALEGRA and Forge3. ALEGRA is shown to be incapable of modeling the Friction Stir Welding process, in large part due to its focus on shock propagation, which causes extremely small time steps. Forge3 is shown capable of modeling of the FSW plunge process in a transient manner, but overestimates the temperature profiles 90% to 100% in comparison to experimentally measured values. It appears that the adiabatic boundary condition is the source of much of the error. It is recommended that future work focus on improving estimates of the boundary conditions utilized in the Forge3 model.

abstract: ABSTRACT Moving beyond Form: Communicating Identity through Dance chronicles the journey of investigating my personal creative process in dance. This was a search for strategies to empower myself creatively, enabling me to move beyond the limitations of a prescribed form or style of dance and communicate ideas that were relevant to me. But on a deeper level, it was an exploration of my capacity to self-define through movement. The challenge led me to graduate school, international study with world-renowned choreographers and to the development of a holistic creative practice, Movement to Meaning. The aim of this creative practice is to express internal awareness through movement, thereby enabling the mover to dance from an internal reference point. In my research, I utilized Movement to Meaning to re-contextualize Sandia, a traditional-based dance that is indigenous to various Mande subgroups in West Africa. This project culminated in a choreographic presentation, Ten For Every Thousand, which was performed in October 2010 at the Nelson Fine Arts Center at Arizona State University in Tempe, Arizona. / Dissertation/Thesis / M.F.A.

A través del análisis hidrológico e hidráulico de la cuenca del río Sandía se generó un mapa de inundación en el distrito de Sandía, en el departamento de Puno. Mediante los modelos numéricos HEC-HMS (Sistema de modelación hidrológica) y HEC-RAS (Sistema de modelación hidráulica) junto con el sistema de información geográfica ARCGIS, el cual procesó la topografía mediante DEM’s (Modelo digital de terreno) provenientes del satélite de la NASA, ALOS PALSAR, se hizo un estudio de inundación que obtuvo como resultado un área inundada de 24.04 hectáreas para un caudal máximo con periodo de retorno de 100 años y 25.61 hectáreas para un caudal máximo con periodo de retorno de 500 años.

Among the available all-quadrilateral mesh generation algorithms progressive-front offers the best quality and robustness. The paving algorithm is a progressive-front technique that generates a two dimensional mesh of all quadrilaterals on planar surfaces. The technique is particularly suited to meshing irregular boundaries with interior holes. This thesis presents an extension of the paving algorithm to generalized three dimensional surfaces. The major problems in three-dimensional surface mesh generation are projection of nodes, calculation of interior angles, and connection of mesh fronts. The solutions to these problems are presented. This work is part of the ongoing CUBIT project at Sandia Labs. The application is written in object oriented style in C++. A description of object oriented programming is given, with the relative merits and drawbacks for engineering applications.
