For many decades, various non-governmental agencies, and political entities have been working to resolve issues relating to Water, Sanitation and Hygiene within developing countries around the world. One area within the world that has sought to resolve this issue for many years is the country of Haiti. Many NGO's have sought to resolve issues of WASH within Haiti through the creation and dispersion of latrines and wells. However due to improper maintenance, these interventions soon become inoperable, putting the health of surrounding citizens in far greater risk. My thesis argues that in order for WASH designs to become sustainable, there must be a joint approach between architecture, landscaping and infrastructure, or an approach termed "infrascaping". Through Infrascaping, my thesis proposes to create a community oriented system through landscaping that focuses on collecting water, cleaning it, and then using it to operate the showers, sinks and toilets through a grey water re-use system. With this approach my thesis aims to represent a model for a sustainable WASH design that can be replicated and reconfigured in various locations around the world. Main Points: 1. Integrating WASH designs into community programs; 2. Manipulating the landscape to produce site conditions that support longterm WASH programs; 3. Using rainfall as a catalyst for site organization and programmatic distribution.

TESIS PARA OPTAR AL GRADO DE MAGÍSTER EN ADMINISTRACIÓN
Juan Castillo P. [Parte I], Patricio González G. [Parte II]El presente modelo de negocio está orientado a ofrecer una experiencia distinta en el autoservicio de lavado de vehículos, específicamente focalizado en el sector norte de la ciudad de Antofagasta, lugar en el cual se tiene proyectado construir 15.000 viviendas (casas y departamentos) hacia el año 2030 apuntando al sector socioeconómico C2 y C3, teniendo como antecedente que Antofagasta es la ciudad fuera de la Región Metropolitana que tiene el mayor registro de vehículos en el país. Full Wash surge precisamente por la carencia de lavados de vehículos cercanos al sector, con un estilo y experiencia diferente al cliente, siendo el lavado su propio core business y no un derivado de otro negocio. El servicio que se ofrecerá al cliente será la experiencia que disfrutaran durante el proceso de lavado exterior de su vehículo realizado por el mismo dueño o conductor, a través de máquinas de hidrolavados de última generación, factor diferencial inexistente a su totalidad en el sector. Como plus y para ser más grata la presencia del cliente, se contará con productos para el cuidado del vehículo que también incluirá en otra vía, ventas de bebidas, cafés y comestibles (Minimarket). Con esto se captará la atención de potenciales clientes de querer disfrutar un momento grato desde la llegada hasta la salida del local y con tiempos óptimos acorde a conformidad del usuario (15 minutos de espera). Con todo lo mencionado se quiere lograr que Full-Wash, se centre en la prestación de servicios de una manera eficiente, rápida, sencilla y de calidad, con tecnología avanzada y auto atención, a través de su slogan “Lavado Express” llame la atención y atraiga a los clientes que no lavan su vehículo a través de este método y así aumentar los ingresos por autoservicio. Respecto de la evaluación financiera del proyecto, consideramos que ha arrojado cifras atractivas, especialmente las asociadas a los indicadores claves para la toma de decisión: VAN: CLP $ 46.142.001 TIR: 22,0%. PAYBACK: 4 años. INVERSIÓN INICIAL: $ 186.484.764 En resumen, si consideramos todos los factores relevantes para la toma de decisión: las condiciones de mercado, la evaluación financiera y de riesgos, entendemos que es un proyecto atractivo con un gran potencial de éxito.

RESUMEN EJECUTIVO
Hoy en día nos encontramos en la evolución global de los negocios, el punto clave está en buscar la innovación de estos para lograr el éxito esperado. Por lo tanto, al iniciar un negocio se busca poder cubrir ciertas necesidades de nuestros clientes que otras empresas no hayan detectado o no se hayan adecuado a la evolución de las exigencias de estos mismos. Teniendo en cuenta todos estos detalles y a las tendencias del mercado se encontró la oportunidad de lanzarnos al mercado con un negocio que cumpla con estas demandas, tendencias y que a su vez sean viables y rentables para quienes las proponen.
Las personas en su día a día sufren de estrés constante ya sea ocasionado por el trabajo o por el tránsito de la ciudad, por ello decidimos crear Team Car Wash. Team Car Wash es un centro de lavado de autos, que no solo se enfoca en brindarle al cliente un lavado de lujo de sus autos, si no que adicionalmente busca cubrir otras necesidades en base a áreas de entretenimiento como una Cafetería, Barbería y un salón de masajes ; todo adecuado para que nuestros clientes puedan desestresarse mientras esperan el lavado de sus autos.
Team Car Wash estará ubicada en Av. Faucett N°330, distrito de San Miguel., teniendo en cuenta que nuestro mercado objetivo está dirigido a estratos A y B.
En el estudio de mercado realizado pudimos notar que este tipo de empresas en el distrito de San Miguel tienen excelente acogida, se observa que el lavado de vehículo se hace con frecuencia semanal (60%), seguido de quincenal (35%) y mensual (5%); lo cual garantiza que es un rubro con demanda constante. Con lo cual nuestra empresa realizara diferentes actividades que hagan que la demanda de nuestro principal servicio (lavado de autos) tenga mayor demanda semanal.
Consideramos que las maneras de satisfacer las necesidades presentes en este sector lo realizaremos implementando un car wash con excelente servicio, uso de productos con estándares de calidad e implementando servicios adicionales que optimicen el tiempo de espera de lavado mediante servicio de corte de cabello, masajes y cafetería.
Finalmente, consideramos que nuestro proyecto es rentable y viable; ya que contamos con un VAN y TIR positivos que van a favor del normal funcionamiento de nuestra empresa e incentivo para posibles inversionistas en nuestro proyecto.

Full textAbstract:
Tunnels have become increasingly important in the development of road networks to meet rising transportation demands. Washing of road tunnels must be performed regularly to ensure traffic safety. The washing procedure generates significant amount of polluted wash water. Before discharge to a receiving water body, treatment is necessary to avoid potential degradation of the water quality. In this study, 12 in situ sedimentation experiments were conducted to evaluate treatment efficiency of sedimentation, with and without the addition of chemical flocculent. The findings showed that untreated tunnel wash water was highly polluted with total suspended solids (804-9690 mg/l), PAHs (0.4–29 μg/l) and heavy metals. Most pollutants were associated with the particulate material. Significant correlations (r2 > 0.95) were found between suspended solids and metals. Efficient removal of pollutants was possible by sedimentation with addition of flocculent. Within 20 hours of sedimentation low concentrations were reached of suspended solids (<15mg/l), PAHs (<0.1 μg/l), Cd (<0.05 μg/l), Cr (< 8 μg/l), Hg (<0.02 μg/l), Pb (<0.5 μg/l) and Zn (< 60 μg/l). The results confirm the possibility to treat tunnel wash water with sedimentation and flocculation and to discharge treated wash water to a recipient, provided particular attention is given to very sensitive water bodies.

Debate continues as to whether seismicity is related to brittle failure during the extrusion of solid dacite spines or is the result of hydrothermal fluids interacting with a crack buried in the volcanic edifice. My model predictions of steady-state conduit flow confirm the strong control that degassing exerts on eruptive behavior. I discuss the necessary role of degassing for extruded material to attain the high density (low vesicularity) of the observed spine material and discuss the implications for generating seismicity. A brittle-failure source of seismicity requires that the gouge elastic properties accommodate some strain, since the magma compressibility in the upper conduit is too low to do so on its own. I also report on a novel method for generating high-resolution digital elevation models of fault surface textures.

Full textAbstract:
The purpose of this capstone project is to tell a place-based story about an often forgotten part of campus: the Wash. Beginning as a likely Tongvan campsite, the Wash, after donation to Pomona College as “Blanchard Park” underwent a series of land-use changes. Originally, a designated green space, its present-day composition includes athletic fields, the organic farm and the historic remnant oak grove. Throughout time the value of the Wash changed with its differing caretakers and inhabitants. To bring attention to this evolving landscape and to inform more sustainable and equitable land use in the future, our project aims to acknowledge past narratives about this place, take stock of its present ecological significance and recommend best practices going forward. We accomplished this by putting together a history of the Wash using indigenous knowledge, archival information, biological surveys and GIS.

Full textAbstract:
El presente proyecto se realizó con la finalidad de promover entre los usuarios, el uso correcto del agua en los centros de lavados de autos, los famosos car wash; debido a que actualmente en estos centros se usa de manera irracional.
La idea del proyecto surge a raíz de la preocupación de unos de los integrantes del curso Desarrollo de Negocios 1, José Sipión quién es ambientalista; logrando así identificar un problema y una necesidad insatisfecha pero a la vez, proponiendo la solución al mismo que conlleva a una idea de negocio. Por este motivo, el proyecto tiene como principal objetivo cubrir la necesidad de la demanda del mercado (clientes), a través de una empresa que le brinde la seguridad y cuidado de su vehículo; cuidando su bienestar a través del cuidado del medio ambiente.
Es así que nace EcoSpray car wash, empresa que busca cubrir una necesidad que se detectó mediante la investigación de mercado, en donde se realizó entrevistas de profundidad en la zona 6 de Lima Metropolitana, a personas que tengan vehículo, considerados millenials y que usen redes sociales. Como resultado de ello, se comprobó que no tienen tiempo tanto para dirigirse a un centro de lavados como esperar a que realicen el lavado de sus vehículos. El servicio que se plantea ofrecer, requiere del uso de un aplicativo móvil, la cual es sencilla y amigable para el cliente, por ella se solicitará el servicio de lavado de autos a domicilio, en el cual se deberá colocar los datos del cliente, la ubicación donde se encuentra el vehículo y método de pago.
Frente a la competencia, son pocas las empresas peruanas que brinden igual o servicios similares al de la compañía, siendo nuestra ventaja competitiva: el tiempo de lavado de un vehículo (30 min. Aprox), dura menos que el tiempo promedio de la competencia. Los productos que se usan para el lavado son eco amigable y la disponibilidad de horarios de atención.
La oficina de la empresa se ubicará en San Miguel, escogimos esta ubicación debido a que se ubica en una zona estratégica y es perteneciente a la zona 6 de Lima Metropolitana, por lo tanto se brindará atención tanto a proveedores, clientes e inversionistas. El proyecto se elaboró con un equipo de trabajo: Vanessa Armas, Alicia Mucha, Renzo Polanco y Jessica Vicos, quienes serán los mismos encargados de dirigir el buen funcionamiento de la empresa, debido a la experiencia del equipo, se ha divido la organización en cuatro áreas: Gerencia General y RRHH, Gerencia de Operaciones, Gerencia de Marketing y Gerencia de Contabilidad y Finanzas.
En cuanto a la inversión del proyecto, se necesita un total de inversión S/ 42,210.00, con una estructura de financiamiento de 80% accionistas y 20% caja Piura. Así mismo, la inversión se recupera en un lapso menor a 2 años (1 año y 4 meses), luego de ello se percibirán las ganancias del proyecto.
Es un mercado nuevo, existe un nicho de mercado bastante aceptable y la competencia es muy poca; por lo tanto existe buena expectativa por este proyecto. Finalmente de acuerdo al análisis de mercado, financiero, etc. realizado por los miembros del equipo, se considera que el proyecto “EcoSpray” es una muy buena alternativa de inversión.The present project was carried out in order to promote among users, the correct use of water in car wash centers, the famous car wash; because at present these centers are used irrationally. The idea of the project arises from the concern of some of the members of the course Business Development 1, José Sipión who is environmentalist; achieving thus identify a problem and an unsatisfied need but at the same time, proposing the solution to it that leads to a business idea. For this reason, the main objective of the project is to cover the need for market demand (customers), through a company that provides the safety and care of your vehicle; taking care of their welfare through the care of the environment. This is how EcoSpray car wash was born, a company that seeks to cover a need that was detected through market research, where in-depth interviews were conducted in zone 6 of Metropolitan Lima, to people who have a vehicle, considered millennials and who use networks social. As a result, it was found that they do not have time to go to a washing center as much as to wait for them to wash their vehicles. The service that is proposed to offer, requires the use of a mobile application, which is simple and friendly for the customer, it will request the car wash service at home, in which you must place the client's data, the location where the vehicle is located and payment method. In contrast to the competition, there are few Peruvian companies that provide the same or similar services to the company, being our competitive advantage: the time of washing a vehicle (30 min.Approx), it lasts less than the average time of the competition. The products used for washing are eco-friendly and the availability of opening hours. The office of the company will be located in San Miguel, we chose this location because it is located in a strategic area and belongs to zone 6 of Metropolitan Lima, therefore it will provide attention to suppliers, customers and investors. The project was elaborated with a work team: Vanessa Armas, Alicia Mucha, Renzo Polanco and Jessica Vicos, who will be the same ones in charge of directing the good functioning of the company, due to the experience of the team, the organization has been divided into four areas: General Management and Human Resources, Operations Management, Marketing Management and Accounting and Finance Management. Regarding the investment of the project, a total investment of S / 42,210.00 is needed, with a financing structure of 80% shareholders and 20% of the Piura case. Likewise, the investment is recovered in less than 2 years (1 year and 4 months), after which the project's profits will be received. It is a new market, there is a fairly acceptable market niche and there is very little competition; therefore there is good expectation for this project. Finally according to the analysis of market, financial, etc. performed by team members, it is considered that the "EcoSpray" project is a very good investment alternative.

Full textAbstract:
This study focuses on the interaction of wash load particles with gravel bed rivers. The effects of excess fine sediment loading to streams on general water quality, contaminant transport, and benthic organism mortality has been well examined. A fundamental assumption in fluvial geomorphology and river engineering is that wash load particles ($d<63mu m$) do not deposit to stream beds, but are instead transported downstream until they deposit in reservoirs or estuaries. The goal of this study is to determine if wash load sized particles can deposit to gravel beds, where within the bed substrate deposition occurs, under what hydraulic conditions it occurs, and how the composition of the bed affects the spatial and temporal deposition pattern. Further, this study attempts to quantify the mass flux of wash load to the bed based on a simple mass conservation model using the aforementioned conditions as model parameters. This was accomplished through a series of experiments in which a mixture of pure kaolinite clay was allowed to deposit at constant shear over an acrylic, gravel, or sand-gravel mixture. Discharge was then increased to determine the effects of increased bed shear stress on deposited material and further wash load interaction with the bed.
Results indicate that wash load will deposit to acrylic, gravel, and sand-gravel beds during conditions where no bedload movement is occurring. Bed composition is the primary factor controlling the mass flux of wash load from the water column to the bed. Deposition on acrylic beds forms clay ripples which translate downstream, while deposition in porous beds occurs primarily within the bed substrate. Shear stress also affects mass flux and the magnitude of its effects are related to the bed composition. Discharge increases below the threshold of bedload movement only cause large scale entrainment of deposited particles over non-porous beds. Periods of higher discharge over porous beds result in continued deposition within the bed substrates.
This research enhances not only our knowledge of sediment processes within fluvial systems, but also allows for the quantification of the wash load portion of those processes given minimal initial condition information. The model developed here may be used within larger hydrologic models when examining contaminant spills or mass loading of stream networks with wash load to estimate the mass deposition to the bed. Instances where wash load is contaminated the mass of contaminated sediment retained by the bed is of great importance to local communities given a reliance of residents on that water source for water, livelihood, and recreation.Master of Science

El proyecto de negocio es constituir una empresa dedicada a brindar un servicio completo en el cuidado de vehículos que brindará diversos servicios siendo el lavado de autos de manera clásica (pañoleros) el servicio ancla seguido por servicios complementarios como el lavado de autos en las instalaciones de los clientes corporativos, la venta de accesorios de mejora, mantenimiento mecánico preventivo, planchado, pintura y otros; este proyecto es innovador dado que nace también con el fin de generar una cadena de servicio consolidada a nivel regional en el cuidado de vehículos
.
Este proyecto se desarrollara en las ciudades de Trujillo, Chiclayo y Piura inicialmente, ya que estas ciudades son el eje económico y comercial del norte del País; en donde se obtuvo que en promedio el 70% de los usuarios del servicio de lavado y venta de accesorios de mejora no se encuentran satisfechos con el servicio que reciben actualmente, ya sea la por la baja calidad de servicio, infraestructura y/o garantía.
A raíz de la existencia de una demanda insatisfecha en el rubro mencionado, una alta competencia informal –aquellos que no ofrecen un buen servicio ni la garantía adecuada- y la ausencia de cadenas regionales que desarrollen estos servicios nace nuestra idea de negocio que llevara el nombre de ”WASH IT!”. Como monto de inversión inicial se estimó S/. 50,000 por sucursal; esta cifra comprende alquiler de local, implementación de infraestructura y compra de los equipos necesarios y relacionados.
Por otro lado se calcularon los indicadores financieros del proyecto dándonos como resultado un Valor Actual Neto (VAN) de S/ 73,892.12 y una Tasa Interna de Retorno (TIR) igual al 166 %, así como la relación costo-beneficio que nos indica que por cada nuevo sol invertido en el proyecto se recuperaría S/. 4.96 al cuarto año, lo que garantiza bases sólidas de rentabilidad, siendo el periodo de recuperación del capital en base a las utilidades en el 3er año.
El análisis de sensibilidad demuestra que en una disminución del 10% en los ingresos del proyecto no lo hace sensible lo que indica que su creación es factible o un incremento del 12% en los gastos del proyecto tampoco lo hace sensible y no presenta pérdidas; en efecto, los indicadores financieros ubican a la empresa con tendencias favorables respecto a las de la industria a partir del primer año; por lo tanto, teniendo en cuenta los factores antes mencionados puede afirmarse que el proyecto “WASH IT!” es viable.

Full textAbstract:
This is a narrative of place, of intersections between people, power, and perception of landscape. The environs of the Columbia River Gorge create a very distinct sense of place. Where once a series of three rapids - the Cascades of the Columbia - blocked industrial upriver transport, now Bonneville Dam and Locks allows smooth passage. To the north the vast 1.3 million acre Gifford Pinchot National Forest dominates the landscape. On the Columbia's banks lies the town of Stevenson, Washington, with Carson a few miles away, in a transitory ecological zone between east and west, at the forest's edge. There, community development has been manifestly influenced by human relationships to the landscape.
Contested visions of place during the nineteenth century resulted in violent conflict and framed debates over place.Examining struggles over who would control access, first to the Cascades of the Columbia, and then to the timber of the Wind River Valley, provides a venue for examining power - of nature, ideas, and changing human cultures as overlapping groups imposed their views of the good life onto the landscape. As each successive group gained power, the relationships of humans to the land, and to one another, changed.
By examining historic connections between river and forest, and between human communities to each, this study identifies multiple meanings of the same environment for different groups. I use a bioregional approach, exploring relationships between land, people and resources on the Columbia's north bank between 1805 and 1913. Power relations at the Cascades and in the forest were determined through conflict, negotiation, and the federal government, with the human relationship to nature influencing outcomes. Conflict often resulted from struggles over access to place, while human groups negotiated their place within the landscape. Nature privileged one group over another through disease, fire, and human perception, while the United States government co-opted place through public land laws, Indian removal, and by measuring and bounding the landscape. Who gained access to the river and forest of the Columbia's north shore, and how they did it, is the focus of this story.

Harvey, Jonathan E. "Reconciling Holocene Alluvial Records in Buckskin Wash, Southern Utah." DigitalCommons@USU, 2009. https://digitalcommons.usu.edu/etd/479.
Full textAbstract:
Most approaches to interpreting alluvial records in drylands fall into one of two categories: (1) The "arroyo problem," wherein workers study cycles of streambed aggradation and degradation in broad, unconstricted alluvial valleys; and (2) paleoflood hydrology, where alluvial sequences in constricted bedrock canyons are interpreted as paleoflood deposits from streams with stable channel grade and geometry. Both approaches can be valid in their end-member settings, but there is confusion about how the two record types relate in a single drainage. We address this disconnect in Buckskin Wash, an ephemeral stream that consists of a broad alluvial reach draining into a tightly constricted slot canyon. By employing detailed sedimentology, stratigraphy, and geochronology in both the alluvial and constricted reaches of the watershed, we test the hypothesis that the slot canyon deposits are anticorrelated to valley-fill deposits upstream, implying that arroyo cutting is driven by episodic flooding.
Alluvial reach deposits are characterized by stratal packages representing incremental, long-term aggradation bound by erosion surfaces representing channel entrenchment. At least four packages younger than ~3 ka are present, the youngest spanning ~0.7 - 0.15 ka. Each is composed of interfingering imbricated gravels, laminated sands, and massive silty clays. Constricted reach deposits consist of five discrete packages, each composed of tabular beds of laminated silty sand that were deposited relatively rapidly. The oldest package dates to ~1.9 - 1.1 ka, whereas the rest of the deposits are younger than ~0.15 ka. Traditional paleoflood techniques would suggest that the constricted reach deposits record a ~1000-year absence of paleofloods followed by ~100 years of frequent, high-magnitude flooding that indeed correlate to arroyo cutting upstream. We argue instead that the constricted reach deposits record an episode of higher preservation potential. Transport of sediment from the alluvial reaches during historic arroyo cutting likely led to a pulse of sediment storage and changed stage-discharge relations in the slot canyon downstream, allowing even moderate floods to overtop existing deposits and be preserved. This new interpretation suggests that, because preservation may be a function of episodic sediment loading from upstream, constricted-reach deposits may not accurately record the paleoflood history of a stream.

La dissémination des cellules cancéreuses et la formation de métastases sont des étapes cruciales dans la progression tumorale et constituent une cause majeure des décès dus au cancer. La métalloprotéase transmembranaire MT1-MMP est un acteur clé impliqué dans le franchissement des barrières tissulaires et le remodelage de la matrice extracellulaire (ECM) par les cellules cancéreuses. MT1-MMP est présente dans des vésicules intracellulaires, appelées endosomes, via lesquels elle est adressée à la membrane plasmique (PM) afin d'y dégrader la ECM. Des travaux menés au laboratoire ont identifié le complexe exocyste (CE) comme un acteur important pour la formation d'invadopodes dans la lignée d'adénocarcinome mammaire MDA-MB-231. Ce complexe multiprotéique (Sec3, Sec5, Sec6, Sec8, Sec10, Sec15, Exo70 et Exo84) est impliqué dans l'arrimage des vésicules intracellulaires à la PM. Des cribles double-hybride ont identifiés la protéine WASH comme partenaire potentiel du CE (via les sous-unités Exo84 et Sec3). WASH est capable d'induire la polymérisation de l'actine en activant le complexe Arp2/3. In vitro, nous avons montré que les complexes WASH et exocyste interagissent physiquement et coordonnent le trafic intracellulaire et l'adressage de MT1-MMP à la PM. Ces résultats mettent en évidence une étroite collaboration entre le cytosquelette d'actine et les mécanismes d'exocytose lors des étapes précoces de dégradation de la ECM ainsi que dans l'invasion tumoraleCancer cell invasion is a prerequisite to tumor progression and metastasis. In order to disseminate, tumor cells must degrade and remodel the extracellular matrix (ECM) in a process that requires the trans-membrane matrix metalloproteinase MT1-MMP, which is a key component of the ECM remodeling apparatus of cancer cells. MT1-MMP overexpression in cancers is associated with increased invasion and metastasis. Many cellular proteins are involved in the transport and delivery of MT1-MMP-containing vesicles to the PM. Previous work from the laboratory identified the exocyst complex (EC) as a key component required for matrix proteolysis and invasion of cancer cells. This multiprotein complex (Sec3, Sec5, Sec6, Sec8, Sec10, Sec15, Exo70 and Exo84) plays essential roles in docking secretory vesicles at the PM for exocytosis. To better characterize this complex, a yeast two-hybrid screen was performed, identifying the protein WASH as a potential partner of Exo84 and Sec3. WASH is a Nucleation Promoting Factor (NPF) able to activate the actin nucleating Arp2/3 complex. Results of the present study showed that WASH and the exocyst complexes interact and localize on MT1-MMP-positive endosomes in MDA-MB-231 breast cancer cells. This study highlight a direct implication of WASH and exocyst complex in ECM degradation by cancer cells through the docking and exocytosis of MT1-MMP-containing endosomes at the PM through connections between these compartments and the extracellular medium. This WASH- and exocyst-dependent MT1-MMP exocytosis mechanism is required for degradation of adjacent tissue by cancer cells during tumour cell invasion

Full textAbstract:
The Little Grand Wash fault and the Salt Wash Graben in the Colorado Plateau of southeastern Utah emit CO2 gas from abandoned drillholes, springs, and a hydrocarbon seep. Similar CO2-charged water has also been emitted in the past, as shown by large localized travertine deposits and veins along and near the fault traces. The faults cut natural CO2 reservoirs and provide an excellent analog for geologic CO2 sequestration. The faults cut a north-plunging anticline of rocks consisting of siltstones, shales, and sandstones from the Permian Cutler Formation through the Cretaceous Mancos Shale. The Little Grand Wash fault has 260 m of throw and the stratigraphic separation across the Salt Wash Graben is 50 m. The fault rocks in the damage zone show hundreds of fractures, which decrease in density farther away from the faults. In specific areas, fractures with the presence of calcite mineralization indicate fluid migration and bleach zones from a few millimeters to 30 cm. This is evidence of past fluid migration directly associated with the fault zone. Calcite mineralization fills these fractures and is also deposited in a variety of other bed forms. Foliated fault gouge, 5 to 20 cm thick, forms clay smear structures with a scaly shear fabric in a zone l0 to 15 cm thick is seen in the fault core. The leakage is constrained to the footwalls of the northernmost faults throughout the area. Clay-rich gouge structures should be effective barriers to cross-fault flow . Well log, surface geologic, and geochemical data indicate that the CO2 reservoirs have been cut by the faults at depth, providing a conduit for the vertical migration of CO2 to the surface, but not for horizontal flow across the fault plane. Even though lateral cross-fault migration may be impeded, this study clearly indicates that there are possible migration pathways for the escape of CO2 from faulted subsurface aquifers, including aquifers faulted by "low-permeability" faults with clay gouge. Three-dimensional flow models show how the fault's maximum permeability in the damage zone is parallel to the faults, and the leakage though the damage zone is localized near the fold axis of the regional anticline. Direct dating of the clay in the fault gouge was done by ExxonMobil with 40Ar/39Ar methods, indicating that fault movement occurred between the middle Eocene and the end of the Miocene. During this time, the Colorado Plateau is interpreted to have been experiencing rapid uplift. The middle Jurassic, upper Jurassic, and Cretaceous rocks at the surface have been uplifted approximately 1.8 km since the end of the Eocene. This uplift may have influenced fault movement in the Colorado Plateau and along the Little Grand Wash fault, and Salt Wash and Ten Mile Graben. In evaluating these deep aquifers for CO2 sequestration, careful design and monitoring of the geological structure and stress regimes must be considered to avoid leakage.

Full textAbstract:
Antifouling paints are a big enemy to the marine ecosystem. Many tons of copper, zinc and other harmful substances are released into the environment each year, in Sweden alone. This study concentrates on the mechanical antifouling method, using boat washes instead, which is a more sustainable alternative. It comes with reduced fuel consumption, increased speed, and moreover, no need for grinding and painting the hull each year. As long as paint residues remain on hulls, but the boat washes are used instead of new paint, it is desired to collect what is scraped of the hulls. By collecting paint flakes and particles accumulated in organic material, the environmental impact is reduced further. The scope of this Master’s thesis is to design a collection device for the portable boat wash Miniwash. A collection device with a cleaning system was developed using the pump effect from the brushes along with an extra pump to press the contaminated water through a bag filter taking most of the particles. One can expect as much as 70% of the harmful particles can be taken care of, according to the filter manufacturer, based on given conditions and filter bag pore sizes. By always having a flow of 8 cubic meters per hour through the cleaning system, it is assumed that not much of the cleaning water will escape, not passing through The bag filter.

Full textAbstract:
Hand-washing compliance was examined by thematic analysis of focus group discussions in nurses, mothers and children. Perceptions in these groups were identical, with the purpose of hand-cleansing seen as self-protection from infection. This assessment is not grounded in microbiology, but is strongly driven by emotion. Two types of hand-cleansing (???hand-hygiene???) behaviour were identified: (a) ???inherent??? hand-washing. This behaviour is taught by mothers to their children early in life. The behaviour occurs when hands have been visibly or ???emotionally??? soiled or feel sticky, and drives most hand-hygiene undertaken in the community; and (b) ???elective??? hand-hygiene, which occurs in the absence of perceived threat. As patient contact by healthcare workers is frequently assessed by healthcare workers as not posing risk, healthcare workers omit much elective hand-hygiene, leading to potential cross-infection. Modelling responses of 754 nurses on the Theory of Planned Behaviour for these two hand-hygiene behaviours in the healthcare setting explained 64% of elective hand-hygiene and 76% of inherent hand-washing intention. Translation of hand-washing behaviour patterns of the community into the healthcare setting is the predominant driver of all hand-hygiene in healthcare workers. In-hospital elective hand-hygiene behaviour is further significantly predicted by belief in the benefit from the activity, peer pressure and role modelling of senior physicians and administrators. For inherent hand-washing intent, only attitudes and peer behaviour are predictive. Time constraints, commonly implicated to explain poor compliance, are important mostly to elective hand-hygiene. Reduction in necessary effort by introducing an alcohol-based hand rub without a concomitant behavioural modification program will therefore have only minimal impact. Further components essential to hand-hygiene programs have been identified. These accord with the outcomes of the modelling and include the need for institutional recognition of hand-hygiene as a priority, overt clinician leadership support, and reinforcement of purpose by both education and performance feedback. In the long-term, society would be best served by altering the entire paradigm of hand-hygiene behaviour with nationwide campaigns based on principles of social marketing. Ideally, hand-hygiene should be taught by mothers and reinforced in early education programs as behaviour that is self-protective but with the defining theme: ???clean your hands, and protect others, not just yourself.???

Full textAbstract:
Clean and safe water is important for the well being of all organisms on earth. Therefore, it is important to reduce harmful emissions from industrial processes that use water in different ways. In vehicle washing processes, water is used in high-pressure processes, as a medium for detergents, and for rinsing of vehicles. The wastewater produced by these functions passes through a water reclamation system. A water reclamation system has two main functions, to produce reusable water to be used in future washing cycles, and to separate contaminants and purify the wastewater so it can be released back into the commercial grid. The reclamation system achieves this by using a combination of different water handling processes, these include: sludge tanks, an oil-water separator, a water reclamation unit, buffer tanks, and a water purification unit. The two components that stand for the more advanced cleaning processes are the water reclamation unit and the water purification unit. In this thesis, in collaboration with the company Westmatic, the water reclamation unit consists of cyclone separators that use centrifugal forces to separate heavy particles and ozone treatment to break up organic substances and combat bad odors. The Purification unit of choice is an electrocoagulation unit that, by a direct current, creates flocculants of impurities that rises to the surface and can be mechanically removed in a water volume inside the unit. This purification process is completely chemical-free thus making the process more environmentally friendly than other purification processes used in other circumstances. This master thesis aimed to develop a dynamic design tool for a modular solution of the different parts in the water reclamation system. This design tool uses specific user input to produce construction information for each instance. As an additional sub-aim, this design tool was linked with a computer-aided design program to produce parametric 3D models with underlying blueprints. This to produce a light solution, that has a short manufacturing time and that are highly customer adjusted. The first course of action was to mathematically define the complete water reclamation system and its components. These sections were described in a flowchart that shows how the different parts interact and operate. From the wash station, wastewater runs trough a course- and fine-sludge tank. From the fine sludge tank, the wastewater is directed in two different directions. Firstly, the water is pumped to the water reclamation unit and to one or multiple buffer tanks to finally be used in the wash station as reclaimed water. Secondly, the water travels to an oil separator, pump chamber, and water purification unit. In the purification unit, 99% of the inlet mass is directed out of the system as purified water. The remaining 1% is directed to a depot that acts like the end stage of the whole system. After all equations were defined and the design was related to the user-defined input flow the design tool was structured. The program of choice to house the design tool is Microsoft Excel. In this Excel document, a user interface with navigation was constructed and the intended user is directed through a series of input pages where input data is defined. This data is used in a normally hidden page where constructional dimensions are calculated. The constructional dimensions are displayed to the user on the second last page. At this stage the Excel document can be connected to a CAD program and 3D models with blueprints can be opened that depend on the output from the Excel file. Additionally, a pipe calculator is provided on the last page of the Excel document where pipe dimensions for different cases can be found. With this solution, glass fiber tanks are molded according to the resulting blueprints that are customer specific. In this way the solution is more adaptive and easier to handle. Additionally, the provided design tool enables an easier and more well-defined methodology when deriving the different needed volume and accompanied constructional dimensions for an arbitrary water reclamation system.

Full textAbstract:
"Globally, inadequate access to safe water and sanitation services, coupled with poor hygiene practices, kills and sickens thousands of children every day and leads to impoverishment and diminished opportunities for thousands more. The United Nations (UN), has recognized water, sanitation and hygiene (WaSH) as major issues that greatly affect the global poor. Under its Millennium Development Goals, the UN has set targets for addressing these issues. Namely, the UN aims to reduce by 50% the proportion of the global population without sustainable access to safe drinking water and basic sanitation by 2015. In 2010, the target of halving the proportion of people without access to improved sources of water was met five years ahead of schedule. Despite progress, 2.5 billion people in developing countries still lack access to improved sanitation facilities. As a result, the vision of WaSH is incomplete. Often, lack of access to basic sanitation is a daily reality for persons residing in informal settlements. The focus of this thesis was an area called Zwelitsha in the informal settlement of Langrug. Located in Stellenbosch Municipality near Cape Town, South Africa, Zwelitsha currently has few functional toilets for its 604 residents. As a result, persons resort to open defecation, contributing to environmental contamination and possible disease transmission throughout the settlement. Thus, sanitation is a significant need for Zwelitsha. Advancing the work of the Cape Town Project Centre (CTPC) – a center location within the Interdisciplinary and Global Studies Division of Worcester Polytechnic Institute – this thesis aimed to address the shortcomings in the provision of sanitation services within Zwelitsha. Through research, urine divergent dehydration and composting toilet systems were found to be the most technically feasible and applicable for meeting the sanitation needs of Zwelitsha. Favorable characteristics of these systems include independence from a connection to water pipes, sewerage, and energy sources and the generation of usable agricultural products. Both household level and community level options were proposed in this thesis. Proposed systems can be integrated into a large-scale WaSH facility with additional services such as water taps, sinks, toilets, showers, laundry stations, recreational areas, gardens, and salons for local business.

The Brushy Basin Member of the Morrison Formation records a time of increased volcanic activity in the North American Cordillera during the Late Jurassic. Sedimentological and petrographic observations in the Brushy Basin, in conjunction with findings of widespread plutonic intrusion in the source areas, point to a volcanic pulse within the Cordilleran magmatic arc. This study investigated the subjacent Salt Wash Member, for the purpose of better constraining the timing of the volcanic pulse. Petrographic and statistical analyses of the Salt Wash sandstone identified statistically significant upsection trends in volcanic rock fragment and plagioclase feldspar at one of the four study areas. The remaining three study areas showed no upsection trends in sandstone composition that would reflect a pulse in volcanism during Salt Wash Member time. It is more likely that the Salt Wash was deposited during a time of volcanic quiescence leading up to the post-Nevadan Orogeny volcanic reactivation. Sedimentology and cementation patterns of the Salt Wash Member were also studied. Cathodoluminescence indicates that the member was well-flushed with shallow formation waters, thus preventing any calcite optical zoning. Luminescence intensity suggests that the Salt Wash Member sediments were cemented at varying depths and within differing Eh-pH regimes. Field-based sedimentological observations support a model of braided stream channel deposition across a semi-arid landscape with streamflow entering the basin from both the south and west

Full textAbstract:
As part of the new navigation lock for Bonneville Dam a new water source for the Bonneville Fish Hatchery must be supplied. The hatchery is located on the Oregon side of the Columbia River downstream of the dam. It requires large quantities of water free from chemical and biological contamination. In addition, the water has to be in a narrow temperature range. Currently the fish hatchery receives its water from a well field that is located on the alluvial terrace downstream of Bonneville Dam. The well field lies in the proposed approach channel for the new lock and has to be abandoned during construction of the lock. For the continued water supply of the hatchery, a new well field will be developed north of the approach channel. Early in the planning phase for the new lock, concerns were raised about the potential impact of the relocation of the well field and the excavation of the new approach channel on the hatchery. To assess these concerns and to assure a continuous water supply during and after construction, a hydrogeologic investigation was initiated. Within the framework of the investigation this study focuses on the analysis of pumping test data and the development of a three-dimensional ground water flow model for the site.
In the first phase of the study, data from eight pumping tests were analyzed. Hydrogeologic properties of the sedimentary units that make up the downstream terrace were determined. The focus was the pre-slide alluvium (PSA) aquifer, the water source for the existing and the future well field. In addition, the nature and location of hydrogeologic boundaries for the ground water system were determined. The results, in conjunction with information from subsurface exploration and laboratory tests, were used to develop a conceptual understanding of the ground water system at the site. The PSA aquifer receives its recharge primarily from leakage through the overlying confining layers over a large area. A direct connection between the Columbia River and the PSA aquifer could not be detected. They appear to be separated by a continuous aquitard layer or by a layer of fine-grained sediments on the river bottom.
Based on these findings, in the second phase of the study, the ground water modeling program HST3D (Kipp, 1987) was used to develop a three-dimensional ground water model for the site. The model was calibrated with data from one of the pumping tests. The calibration was then verified with a second set of conditions including pumping from shallow and deep wells. Water levels in the deep PSA aquifer and the shallow unconfined aquifer were successfully matched. A satisfactory match of observed conditions was possible with only slight modifications of the hydrogeologic parameters determined by pumping test analysis and based on the conceptual model developed in the first phase of the study. It appears that a continuous aquitard layer separating the Columbia River and the PSA aquifer, with the aquifer receiving recharge through vertical leakage over a large area, is a valid representation of the aquifer system.

Full textAbstract:
In order to avoid harmful substances ending up at the municipal sewage treatment plants, it is important to purify the wastewater at the source. One such source is the wheel washers available in many tire garages which are used to wash the wheels on our vehicles when we change between summer and winter tires. It is important to wash the wheels before storage, to extend the tires lifetime. The purpose of this study is to find a green innovative solution for reduction of emissions of heavy metals at the source, so that the sludge from the sewage treatment plants can be used as fertilizer. The target is to find a wheel wash method which leads to compliance with the guidelines for car washers, and that also provides a better washing result than with the existing method. Chemical analyzes of water samples have been performed and the cleanliness of the wheels has been checked visually. As there are no specific emission requirements for wheel washes, the results have mainly been compared with current guidelines for vehicle washes. A new washing and flocculation method have been developed during the study. The proposed new method is suitable as pretreatment of the water before discharging it, as it reduces metal emissions and provides better washing results compared to the old method. Significantly larger number of wheels may be washed in one session, which leads to a reduction of water- and energy consumption since the machine can be emptied and cleaned less often. For many years there has been an environmental adaption to eco-friendly car washers, so the opportunities should be good for wheel washers to win goodwill and market advantages by being profiled with an environmentally adapted washing method.För att undvika att miljöskadliga ämnen hamnar i de kommunala reningsverken är det viktigt att rena avloppsvattnet vid källan. En sådan källa är de hjultvättmaskiner som finns på många verkstäder och som används för att tvätta hjulen på våra fordon i samband med skifte mellan sommar- och vinterdäck. Det är viktigt att tvätta hjulen före förvaring, för att förlänga däckens livslängd. Syftet med denna undersökning är att hitta en grön innovativ lösning för att främja uppströmsarbetet, dvs att rena utsläppen av tungmetaller vid källan, så att slammet från våra reningsverk kan användas som gödningsmedel. Målet är att finna en metod för hjultvätt som medför att riktlinjerna för fordonstvättar uppfylls, och som samtidigt ger ett bättre tvättresultat än befintlig metod. Kemiska analyser av vattenprover har utförts och renheten har kontrollerats visuellt. Eftersom det saknas specifika utsläppskrav för hjultvättar, har resultaten i första hand jämförts med gällande riktlinjer för fordonstvättar. En ny tvätt- och flockningsmetod har utvecklats under studiens gång. Den föreslagna nya metoden är lämplig som förbehandling av vattnet innan utsläpp, eftersom den sänker metallutsläppen samt ger ett bättre tvättresultat jämfört med den gamla metoden. Betydligt fler hjul kan tvättas per tvättomgång vilket innebär en minskning av vatten- och energiförbrukningen eftersom maskinen behöver tömmas och rengöras mer sällan. Under många år har det skett en miljöanpassning av fordonstvättar, så möjligheterna borde vara goda för att även hjultvättar ska kunna vinna goodwill och marknadsmässiga fördelar genom att profilera sig med en miljöanpassad tvättmetod.

Full textAbstract:
Tower Mountain Caldera is the main feature of an Oligocene volcanic field located in the Umatilla National Forest, eastern Oregon. It is perfectly suited to investigate models of rhyolite petrogenesis as all of the important rock components for evaluating generation models are present in a single location and thus are presumably related; basalts, intermediate igneous rocks (which consist of older plutons and younger volcanic rocks, which are ~coeval with rhyolites), metamorphic basement rocks of significant grade, and rhyolites of varying composition. The formation of the caldera produced the Dale Tuff, which comprises the intra-caldera and outflow facies. 40Ar/39Ar dating places the age of the tuff at 32.66 ± 0.36 Ma. Post-caldera rhyolites erupted along apparent ring fractures and elsewhere. Radiometric U-Pb dating of zircons from three of these rhyolites yielded ages of 32.167 ± 0.020 Ma (#CH07a), 31.798 ± 0.012 Ma (#TM5), and 31.426 ± 0.016 Ma (#CH08a). All rhyolites at Tower Mountain range from low to high silica varieties. Some of the post-caldera rhyolites are chemically similar to the Dale Tuff, such as sample CH07a, and have compositions typical of rhyolites of calc-alkaline volcanic centers (I-type rhyolites), while others are similar to A-type rhyolites (CH08a and TM5). The ages indicate that the calc-alkaline rhyolites were followed by the A-type rhyolites. The petrogenetic relationships between the various rocks types were evaluated. Partial melt modeling based on experimental melts produced from crustal material indicates that batch partial melting of metamorphosed high silica crustal material modified by the addition of more primitive mafic material by assimilation/contamination is the most likely source for the Tower Mountain rhyolites.

Full textAbstract:
Glaciers respond to local climate changes making them important indicators of regional climate change. The North Cascades region of Washington is the most glaciated region in the lower-48 states with approximately 25% of all glaciers and 40% of the total ice-covered area. While there are many on-going investigations of specific glaciers, little research has addressed the entire glacier cover of the region. A reference inventory of glaciers was derived from a comparison of two different inventories dating to about 1958. The different inventories agree within 93% of total number of glaciers and 94% of total ice-covered area. To quantify glacier change over the past century aerial photographs, topographic maps, and geologic maps were used. In ~1900 total area was about 533.89 ± 22.77 km2 and by 2009 the area was reduced by -56% ± 3% to 236.20 ± 12.60 km2. Most of that change occurred in the first half of the 20th century, between 1900 and 1958, -245.59 ± 25.97 km2 (-46% ± 5%) was lost, followed by a period of stability/growth in mid-century (-1% ± 3% from 1958-1990) then decline since the 1990s (-9% ± 3% from 1990-2009). The century-scale loss is associated with increasing regional temperatures warming in winter and summer; precipitation shows no trend. On a decadal time scale winter precipitation and winter and summer temperatures are important factors correlated with area loss. Topographically, smaller glaciers at lower elevations with steeper slopes and higher mean insolation exhibited greater loss than higher, gentler more shaded glaciers.

Full textAbstract:
Between October 9, 1991 and October 16, 1991 a fire burned 577 hectares in the Columbia River Gorge near the west end on the Oregon side. All of the area burned consisted of second growth Pseudotsuga menziesii and the accompanying understory. This was the first disturbance of this magnitude in this part of the Columbia River Gorge since 1902. The purpose of this study was to examine the pattern of understory recovery in the first two years following the fire. This study also sought to learn: 1) how Pseudotsuga menziesii seedlings are recruited into the population, 2) how quickly the litter layer is a reforming, and 3) how quickly snags and downed logs are recruited into the understory. Four 800 square meter circular plots were established within the burned area of the Columbia River Gorge. Two plots were designated sun plots since the fire had killed the overstory. The other two were designated shade sites since the canopy over them was still intact. Twenty five randomly placed sample units (20 x 50 centimeters) were placed in each main plot. The plots were then sampled at approximately onemonth intervals from May through September of 1992 and 1993. The frequency and percentage of cover was recorded for all plant species that occurred in each sample unit. The data from 1992 and 1993 were compared by date of visit and type of plot, either (sun or shade) using the Pearson Goodness-of-Fit Test to examine and compare differences in the extent of cover and distribution of understory species. No significant differences were found. An increase in species richness and relative abundance of understory species was noted between pre-fire data collected by the US Forest Service and what I found. However, statistical analysis was not possible because of the limited data collection in the pre-fire sample.

Full textAbstract:
Access to water from San Antonio Creek was critical in Claremont’s growth from a small stop on the Santa Fe Railroad to an agricultural powerhouse and an elite college town. While Claremont has sought to distinguish itself from surrounding communities since its founding in 1882, the innovative Pomona Valley Protective Association (PVPA) aligned Claremont with the City of Pomona and its other neighbors in a scheme to conserve the Creek’s resources at the turn of the century. Organized around the discovery of local confined aquifers and the development of a strategy to recharge them with water from the San Antonio Creek, the Association was a contradictory moment of cooperation in an otherwise highly contentious zero-sum game of water rights politics. As conflicts wore on, the PVPA quietly orchestrated the purchase of large tracts of land in the San Antonio Creekbed, where the construction of diversion dams and spreading grounds served dual purposes of water conservation and flood control. As dam building in the Creekbed continued, large tracts of the previously undevelopable Wash were transferred to the aggregate mining institutions that gouged the area’s many gravel pits.
This thesis uses the story of the PVPA and the contemporary example of the Claremont University Consortium Gravel Pit to explore the context of development in the San Antonio Creek Wash. Understanding the political and social contexts of the gravel quarry problem reveals possibilities for a more integrative, conscious, and sustainable approach to improving the former gravel quarries that currently occupy the Wash landscape.

Full textAbstract:
For appropriate management of any stretch of coastline, it is desirable to understand (and ultimately to be able to predict) the exchange, transfer and storage of material at the landocean boundary. To this end, the multidisciplinary Land-Ocean Interaction Study (LOIS) was set up by the UK Natural Environment Research Council (NERC), focusing chiefly on eastern England as an example. Distinction between short-term fluctuations and long-term trends is particularly important when devising predictive models of coastal change. Within LOIS, the Land-Ocean Evolution Perspective Study (LOEPS) provided data on a Holocene time scale using evidence from the sediment record of east coast sinks including the Humber, the Fens and the North Norfolk coast. As part of LOEPS, the present study centred on the Wash-Fenland Embayment, the largest accumulation of Holocene tidal sediments in Britain. Since initial marine inundation of the area around 7,000 years BP, approximately 24 km' of sand and mud have been deposited by vertical and lateral accretion under varying rates of sea-level rise. However, in the last 50 years, parts of the shoreline have started to erode, raising questions over sediment supply and other conditions necessary for maintaining the position of the intertidal zone. The main aim of the work presented in this thesis was to ascertain the main sources of sediment supplied to the Fenland and adjacent Lincolnshire coast. Selected tidal sediments from early Holocene to recent age were compared with a range of potential source lithologies. The latter included sections of eroding coast between Holderness and North Norfolk and local strata exposed within the embayment and its river catchments. In the Fens, use of chemical ratios showed the majority of Holocene sediment to be well mixed and very homogeneous, variations in bulk chemical data mainly being a function of sediment grade. However, samples with anomalous chemical ratios were identified at the base of the succession close to the landward margins. Grain-size specific analyses of these samples suggest that they have a similar composition to lithologies from Fenland river catchments and the floor of the embayment. For example, clay mineralogy indicated an early Holocene fluvial input of Oxford Clay at Adventurer's Land. In a similar way, surface area, mineral magnetic analyses, optical mineralogy and SEM of anomalous sand samples show quantitatively and qualitatively the links between selected non-marine sources and these early Holocene sediments. The bulk of the Fenland sediment appears to have been well mixed in the North Sea sediment pool prior to deposition. Comparisons of the potential marine source lithologies showed the fine fraction of the glacial tills to the north and east of the embayment to be chemically very similar. On the basis of clay mineralogy, subtle differences between Devensian and Anglian Tills were identified, and Fenland sediment was found to have an intermediate composition. The sand fraction of most Devensian Till samples could be distinguished from the more quartz-rich sand fraction of the Anglian Tills, and quantitative analyses of surface area and magnetic properties of selected Fenland samples suggest till eroding from the Lincolnshire foreshore is the most likely source. Particle size analysis, summarised using Principal Components Analysis (PCA), proved successful in characterising sediments according to depositional environment. Grain-size data indicated a general fining-upwards trend in the sand fraction. In the embayment as a whole, vertical accretion was accompanied by lateral progradation indicating that sediment supply was more than sufficient to keep pace with sea-level rise. The use of particle size analysis together with PCA seems widely applicable to studies of modern and Holocene sedimentary environments, estuarine sedimentation history and consideration of long term sediment budgets. Chemical ratios appear to have potential as first indicators of changing sediment source.

Park, Laura. "Function and regulation of the WASH complex in the endocytic cycle." Thesis, University of Glasgow, 2012. http://theses.gla.ac.uk/3815/.
Full textAbstract:
The WASH complex is highly conserved and consists of the actin nucleation promoter, WASH, and several regulatory subunits; Strumpellin, SWIP, ccdc53 and FAM21. Previously, it has been shown that WASH directs construction of actin coats on lysosomes. This actin coat is required for removal of V-ATPase complexes from lysosomal membranes, allowing neutralization and maturation to post-lysosomes. WASH null cells are blocked at the acidic lysosome stage and are thus unable to perform exocytosis. We now show that FAM21 acts at a different step in the same pathway. FAM21 nulls are still blocked in exocytosis, but the remaining complex is functional in removal of V-ATPase, allowing progression to post-lysosome. We hypothesize that the role of FAM21 is to release the WASH complex from post-lysosome membranes in order to allow recycling back to newly formed acidic lysosomes. We have also shown that capping protein interacts with the WASH complex through FAM21, and this interaction is essential for progression to exocytosis, likely contributing to the mechanism by which FAM21 regulates and releases the WASH complex from post-lysosomal membranes.

Full textAbstract:
The study ”Wash away greenwashing” aims to analyze crisis communication caused byaccusations of greenwashing and whether the accused organizations succeed in repairing their image. Greenwashing is when an organization is trying to portray themselves as more environmentally friendly than they actually are. The chosen organizations are Sveaskog, Preem and Svenskt Flyg, who have been accused of greenwashing and won the annual anti- prize which is voted forward by the swedish environmental organization Jordens Vänner. The study conducts a qualitative rhetorical analysis and a smaller quantitative content analysis based on theories about the rhetorical situation, ethos, pathos and logos, green rhetoric and Image repair theory. The study analyzes four different media texts belonging to the organisations which are called ”Kommentar till Svenska Greenwashingpriset”, ”Sveaskog välkomnar en dialog om skog”, ”Så ska Preem hantera Svenska Greenwashingpriset” och ”De får Svenska Greenwashingpriset 2017”. The result of the analysis shows that all of the accused organizations are using the different theory’s within crisis communication, but theextent differs. The main thing to achieve effective crisis communication is to have available information concerning the accusations and that the crisis communication should be as correct and balanced as possible regarding rhetoric. The conclusion is that Sveaskog is the most efficient with their crisis communication and thus succeeds in repairing their image after the accusations in the best way.Studien ”Wash away greenwashing” ämnar analysera kriskommunikation som uppstått efter anklagelser om greenwashing och huruvida organisationerna lyckas reparera sin image. Greenwashing är när en organisation försöker framställa sig som mer miljövänliga än vad de i själva verket är (Jordens Vänner, u.å.a). De valda organisationerna är Sveaskog, Preem och Svenskt Flyg, tre organisationer som anklagats för greenwashing och har vunnit det årliga antipriset som röstas fram och delas ut av miljöorganisationen Jordens Vänner (Jordens Vänner, u.å.a). Studien genomför en kvalitativ retorisk analys och en mindre kvantitativ innehållsanalys analys som utgår från teori om retorisk situation, retoriska appellformer, grön retorik och Image Repair Theory. Genom analysen analyseras fyra olika medietextertillhörande organisationerna vid namn ”Kommentar till Svenska Greenwashingpriset”, ”Sveaskog välkomnar en dialog om skog”, ”Så ska Preem hantera Svenska Greenwashingpriset” och ”De får Svenska Greenwashingpriset 2017”. Resultatet visar att avsändarna Sveaskog, Preem och Svenskt Flyg alla använder sig av strategier inom kriskommunikation, men vid olika antal tillfällen och genom olika uttryck. Det huvudsakliga för att kunna uppnå effektiv kriskommunikation är att det ska finnas tillgänglig information angående anklagelserna och att den ska vara så korrekt och retoriskt balanserad som möjligt. Trots att alla avsändare använder sig av olika retoriska appellformer, så är slutsatsen att det är Sveaskog som lyckas mest effektivt med sin kriskommunikation och därmed lyckas reparera sin image efter anklagelserna på bästa vis.

Full textAbstract:
In this Master of Arts Thesis in Anthropology I examine the controversy in the Okanagan Valley over the introduction of GM seed technologies into local agricultural processes. I explore via a multi-sited ethnography how local fruit farmers in this region view GM seed technologies and their perception of how these technologies will impact their farming practices. I argue that (a) the use of GM seeds as currently regulated in Canada threatens to erode farmers' local knowledge of plant breeding and that (b) this erosion is of consequence not only to local farmers but to society generally because the environmental knowledge and skills possessed by local farmers is crucial to the protection of biodiversity, environmental sustainability, and food security.
