Fertilizante Natural: Agro Dust / Natural Fertilizer: Agro Dust

Avendaño Gil, Gianfranco Emilio, Bazán Durand, Daniel Antonio, Maza Fajardo, Rodrigo Alonso, Ochoa Bustamante, Juan Diego, Torres Paredes, Maria Elizabeth 27 November 2019 (has links)
El presente proyecto se basa en la producción y comercialización de fertilizante natural y biodegradable, que sirve como bio-estimulante para las plantas ornamentales, teniendo como valor adicional ser un retenedor de agua de riego durante 20-21 días aplicando una sola vez el producto. Elaborado a base de cáscara de naranja y palta, nuestro negocio va dirigido a habitantes de Lima Moderna correspondientes a los estilos de vida conservador, moderno y sofisticado que posean plantas y/o pequeños jardines pertenecientes a los niveles socioeconómicos (NSE) A, B y C, además de mostrar preocupación por el medio ambiente. El empaque del producto va a ser una bolsa de papel kraft biodegradable con una capacidad 250 gramos. Se realizó una total de entrevistas a 30 personas para validar la existencia del problema encontrado y el interés e intención de uso del producto de nuestros posibles clientes. Además, con fines de hacer este proyecto escalable para el rubro de la agricultura, se contactó a dos expertos en agronomía para validar el producto y algunos aspectos sobre la posible escalabilidad de este. El desarrollo del proyecto se encuentra dividido en dos puntos, los cuales son la validación del plan de negocio y desarrollo del plan de negocio. Para la ejecución del proyecto se requirió una inversión de 21,454 soles, obtenidos a base de capital propio de los accionistas, quienes estiman recuperar dicha inversión en el primer año de operación. La rentabilidad brindada a los accionistas es de 249% lo cual hace nuestro proyecto un negocio rentable. / The present project is based on the production and commercialization of natural and biodegradable fertilizer, which serves as a bio-stimulant for ornamental plants, with the additional value of being a water retainer for 20-21 days by applying the product once. Made with orange and avocado peel, our business is aimed at inhabitants of Modern Lima corresponding to conservative, modern and sophisticated lifestyles that have plants and / or small gardens belonging to socioeconomic levels (NSE) A, B and C, in addition to showing concern for the environment. The product packaging is going to be a biodegradable kraft paper bag with a capacity of 250 grams. A total of interviews were conducted with 30 people to validate the existence of the problem encountered and the interest and intention of using the product of our potential customers. In addition, in order to make this project scalable for the field of agriculture, two agronomy experts were contacted to validate the product and some aspects of its possible scalability. The development of the project is divided into two points, which are the validation of the business plan and development of the business plan. For the execution of the project, an investment of 21,454 soles was required, obtained based on the shareholders' own capital, who consider recovering said investment in the first year of operation. The profitability provided to shareholders is 249% which makes our project a profitable business. / Trabajo de investigación

La théorie des humeurs chez Heidegger : esquisse des fondements dans Sein und Zeit

Ethier-Delorme, Keith January 2015 (has links)
Résumé : « Wege, nitch Werke ». L’exergue de la Gesamtausgabe donne une indication précieuse pour quiconque souhaite lire et comprendre la pensée de Heidegger. Son œuvre se distingue des classiques de la tradition philosophique par le fait qu’elle ne cherche pas à établir une doctrine. Elle vise plutôt à reprendre à bras-le-corps une seule et même question : la Seinsfrage. Heidegger l’a retournée de maintes façons, parfois en puisant dans les préjugés au sujet de l’Être, parfois en empruntant des chemins de pensée plutôt inexplorés, mais à chaque fois il étonne. Le lecteur habitué à la rigidité conceptuelle, aux évidences cartésiennes et aux règles logiques de l'esprit, trouve peut-être en Heidegger son plus grand défi parce qu’il adhérait à une pensée-en-chemin (Zu Denken Wege) qui accueille l'errance et la pause, le silence et le tournant. Il invite le lecteur à prendre le pas, à risquer les chemins qui ne mènent nulle part ― Holzwege ―, à ne pas hésiter à faire un pas en arrière (Schritt zurück). La Gesamtausgabe oblige un certain inconfort pour la pensée. Ce mémoire de maîtrise est consacré à l’examen de la fonction phénoménologique des humeurs (Stimmungen) et à l’importance que leur accorde Heidegger, à partir d’une lecture de Sein und Zeit, tout particulièrement. La recherche a pour hypothèse de travail qu’on y retrouve une théorie des humeurs appréciable, bien que ne lui soit pas réservée une analyse systématique dans l’œuvre. Malgré cela, ce mémoire fait la démonstration, en quelques chapitres, que Sein und Zeit contient des éléments théoriques qui permettent de fonder cette théorie. Au final, le mémoire explore brièvement les humeurs analysées par Heidegger. C’est l’occasion de voir comment la théorie des humeurs s’inscrit véritablement dans la pensée du philosophe. La thèse défendue dans ce mémoire pourrait être reprise et approfondie par une étude doctorale, ce qui donnerait peut-être une clef supplémentaire pour contribuer à l'élaboration d'une lecture intégrale de la Gesamtausgabe. / Abstract : The highlight of the Gesamtausgabe gives a valuable indication for anyone who wants to read and understand Heidegger's thought. His work part from the philosophical tradition in that does not seek to establish a doctrine. Rather, it is intended to tackle the question of Being (Seinsfrage). Heidegger has posed it in many ways, sometimes by challenging our common sense about the “Being”, sometimes by exploring new paths of thinking, each time surprising us. Someone familiar with rational assertion, methodological pattern and logical rule, may find Heidegger really hard to understand because he assumes what he calls a « thought-in-way » (Wege Zu Denken), which welcomes silence and wandering. Heidegger invites the reader to try pathways that lead nowhere at first sight — Holzwege —, and sometimes to take a step back (Schritt zurück) from what he thinks. The Gesamtausgabe is definitively a challenge for the thought. The main goal of this master’s thesis is to examine the phenomenological function of moods (Stimmungen) and the importance we should give to them, from a reading of Sein und Zeit, especially. The aim is to find in it a theory of moods, even if Heidegger did not analyze them systematically. Nevertheless, this essay outlines, in just a few chapters, the reasons why we can pretend there is a such theory and why the moods have a significant phenomenological function. Finally, we explore the moods analyzed by Heidegger so we can see how his theory is truly embodied. This research could be taken further in a doctoral study, which would perhaps contribute to a more comprehensive interpretation of the Gesamtausgabe.

3D Thermal Mapping of Cone Calorimeter Specimen and Development of a Heat Flux Mapping Procedure Utilizing an Infrared Camera

Choi, Keum-Ran 02 February 2005 (has links)
The Cone Calorimeter has been used widely for various purposes as a bench - scale apparatus. Originally the retainer frame (edge frame) was designed to reduce unrepresentative edge burning of specimens. In general, the frame has been used in most Cone tests without enough understanding of its effect. It is very important to have one - dimensional (1D) conditions in order to estimate thermal properties of materials. It has been implicitly assumed that the heat conduction in the Cone Calorimeter is 1D using the current specimen preparation. However, the assumption has not been corroborated explicitly to date. The first objective of this study was to evaluate the heat transfer behavior of a Cone specimen by examining its three - dimensional (3D) heat conduction. It is essential to understand the role of wall lining materials when they are exposed to a fire from an ignition source. Full - scale test methods permit an assessment of the performance of a wall lining material. Fire growth models have been developed due to the costly expense associated with full - scale testing. The models require heat flux maps from the ignition burner flame as input data. Work to date was impeded by a lack of detailed spatial characterization of the heat flux maps due to the use of limited instrumentation. To increase the power of fire modeling, accurate and detailed heat flux maps from the ignition burner are essential. High level spatial resolution for surface temperature can be provided from an infrared camera. The second objective of this study was to develop a heat flux mapping procedure for a room test burner flame to a wall configuration with surface temperature information taken from an infrared camera. A prototype experiment is performed using the ISO 9705 test burner to demonstrate the developed heat flux mapping procedure. The results of the experiment allow the heat flux and spatial resolutions of the method to be determined and compared to the methods currently available.
