El presente proyecto tiene como propósito mejorar el bienestar de las personas de nivel socioeconómico A y B, ayudándolas a disminuir el estrés y dolores musculares que presentan en distintas partes del cuerpo por el estilo de vida, con el objetivo de brindarles confort y comodidad, evitando enfermedades o riesgos crónicos a futuro y que puedan realizar sus actividades diarias sin molestias y malestares corporales. Teniendo en cuenta la problemática de salud y bienestar, además la coyuntura actual debido al Covid 19 se ha decidido afrontar uno de los problemas más comunes que asecha a las personas que es el estrés y dolores musculares mediante almohadas terapéuticas que ayudarían a reducir estos problemas teniendo en cuenta el distanciamiento y trabajo en casa. Las almohadas Comoditi nace bajo el concepto de comodidad y uso donde las personas lo prefieran más, por eso mismo estarán disponibles en distintos puntos de venta donde el público suele concurrir como gimnasios, centros comerciales y centros de salud por ser un producto de bienestar. Comoditi empezara con dos líneas de producto tamaño estándar y pequeño con el objetivo de vender en el primer año 7,885 almohadas considerando un plan de ventas por estacionalidad. El proyecto se trabajará en un periodo de tres años y para poder iniciar se necesitará una inversión inicial de S/ 92,714 compuesta de un 50% de aporte de los cuatro accionistas y otro 50% financiado a 12 meses. / The purpose of this project is to improve the well-being of people of socioeconomic level A and B, helping them to reduce stress and muscular pain that they present in different parts of the body due to lifestyle, with the aim of providing them with comfort and convenience, avoiding chronic diseases or risks in the future and that they can carry out their daily activities without discomfort and bodily discomfort. Taking into account the problems of health and well-being, in addition to the current situation due to Covid 19, it has been decided to face one of the most common problems that plagues people, which is stress and muscle pain through therapeutic pillows that would help reduce these problems by having consider distancing and work at home. The Comoditi pillows were born under the concept of comfort and use where people prefer it the most, which is why they will be available in different points of sale where the public usually attends such as gyms, shopping malls and health centers for being a wellness product. Comoditi will start with two product lines, standard size and small, with the aim of selling 7,885 pillows in the first year, considering a seasonally adjusted sales plan. The project will be worked over a period of three years and to start it, an initial investment of S / 92,714 will be required, consisting of a 50% contribution from the four shareholders and another 50% financed over 12 months. / Trabajo de investigación

This study explores the nature of writing and the sorts of presence that writing gives us access to. This understanding of writing includes not only all speaking and all writing in the narrow sense of marks on a page, but goes beyond this to include the sense in which Derrida uses the term ‘writing’ in Of Grammatology, to mean a broad and complex process of the construction of textual traces or presences necessarily brought about through the structural mechanism of difference inherent in the writing process (Derrida, 1997). This study argues that writing is a system that creates Subjects or selves as the writing happens. It suggests that writing is a remarkable site from which to explore the construction of selves, because it gives us access to (partially) identifiable presences, in the apparent absence of the writer. It goes on to demonstrate that this identity can be distinguished through written traces of difference left for the reader to decipher, by analysing different aspects of the plot and writing devices in Peter Greenaway’s film The Pillow Book and in Kafka’s short story In the Penal Colony. These two texts are considered particularly relevant to this study, in that they both explicitly deal with the contradictory nature of writing and how it relates to the Being (there or the contextualised Being of Dasein) and being (in general), the life and death, the empowerment and destruction of the Subjects that writing sets up. Both texts explore salient aspects of writing on the human body. The study uses these texts as a platform for speculation about the kind of presence that can be traced through writing, and proposes that the written Subject is multiple, contradictory and reflexive, connected and related, and that it is impermanent and has a deferred presence. Finally, this written Subject is also explored in the context of Foucault’s expositions of the self in texts such as Technologies of the self (Foucault, 1994) and ‘What is an Author?’ (Foucault, 1977) in answer to his question Who are we in the present, what is this fragile moment from which we can’t detach our identity and which will carry our identity away with itself?

Afin de préciser l'origine des volatils terrestres et les flux actuels et passés vers l’atmosphère, de nombreuses études s’intéressent à la composition du manteau. Ce réservoir est échantillonné naturellement lors des éruptions volcaniques, mais une grande partie des gaz est alors émise dans l'atmosphère, de sorte que la composition des volatils du manteau reste peu contrainte. Nous cherchons à préciser les mécanismes de dégazage sous les dorsales océaniques afin de corriger ces fractionnements. L'analyse (He-Ne-Ar-CO2) de verres basaltiques issus de la dorsale des Galápagos, dans la zone d'influence du point chaud des Galápagos, montre que la composition en volatils des laves s'explique par distillation de Rayleigh d'une source unique. Cette source est distincte de celle du point chaud (isotopes du néon), impliquant un dégazage en profondeur du panache ou une hétérogénéité spatiale de sa composition.Plusieurs verres volcaniques issus de la dorsale Atlantique et Est Pacifique ont été imagés par micro-tomographie aux rayons X. L'étude met en évidence des mécanismes de nucléation et de croissance des bulles différents sous les deux dorsales. De la convection en périphérie de la chambre magmatique avant l’éruption a été mise en évidence par l’étude pétrologique des verres. Les vésicules imagées ont ensuite été ouvertes individuellement sous vide par ablation laser et analysées (CO2, 4He, isotopes de l'argon). La composition des bulles est hétérogène dans certains échantillons et compatible avec une distillation de Rayleigh. Les tendances de dégazage obtenues permettent d'obtenir localement la composition de la source mantellique, qui est hétérogène.L'étude permet également d'appréhender l'hétérogénéité des rapports 40Ar/36Ar dans les chambres magmatiques par la technique d’ablation laser qui diminue la contamination atmosphérique par rapport à la technique classique de broyage / The composition of mantle volatiles is related to the origin of Earth's volatiles and to the past and present volatile fluxes to the atmosphere. Although this reservoir is naturally sampled during volcanic eruptions, most of the volatiles are lost to the atmosphere during this event, thus the composition of mantle volatiles is still uncertain. We try here to precise the processes of degassing below mid-oceanic ridges to correct the lava compositions for degassing.The He-Ne-Ar-CO2 analyses of basaltic glasses sampled along the Galapagos Spreading Center, in the area of influence of the Galapagos hotspot, show that the volatile composition of lavas is fully explained by a Rayleigh distillation of a unique source distinct from the plume source. These results imply that the plume degasses at depth or is heterogeneous.Several volcanic glasses from Mid-Atlantic ridge and East Pacific Rise have been imaged by X-rays microtomography. The mechanisms of vesicle nucleation and growth appear to be different below the two ridges. A step of convection at the magma body margin has been evidenced by the petrologic study of the glasses. Imaged vesicles have been subsequently opened under vacuum by laser ablation and analysed (CO2, 4He, argon isotopes). We observe, depending on the samples, either a single composition for all bubbles, or variations in composition between bubbles consistent with a trend of equilibrium degassing in an open system. The trends of degassing allow extrapolating locally to the volatile composition of the mantle source, which is heterogeneous. We also studied the heterogeneity of 40Ar/36Ar ratios in magmatic chambers using the laser opening method, which lowers the contribution of atmospheric gases compared to the classical crushing method
