Proyecto Naturessa

Dávila Ramírez, Jaclyn Lesly, Faya Vilchez, María De Jesús, Guillén Cueva, Erika Isabel, Rondón Camiluaga, Jennifer Sophia 29 November 2019 (has links)
El presente proyecto lleva el nombre de “Naturessa”, el cual es una empresa que ofrece al público la alternativa de adquirir una pasta dental ecológica elaborada con insumos naturales y con envase eco amigable; esto con la finalidad de brindar beneficios a la salud del consumidor y colaborar con el cuidado del medio ambiente. Para la realización de este proyecto se identificaron dos incertidumbres que existen en el mercado de salud bucal. Por un lado, identificamos que las pastas dentales tradicionales contienen insumos que son dañinos para la salud humana, ya que causan problemas como irritaciones, afecciones en los huesos, cáncer, entre otros. Asimismo, los consumidores no se encuentran informados de estos males. Por otro lado, las pastas dentales tradicionales son causantes de contaminación ambiental, ya que son producidos con micro plásticos que funcionan como agentes para eliminar la suciedad dental y están contenidos en envases de plástico. Naturessa está dirigido a hombres y mujeres del nivel socioeconómico A y B de la zona 7 de la ciudad de Lima, los cuales comprende los distritos de Miraflores, San Isidro, San Borja, Surco y La Molina. Además, estas personas se preocupen por utilizar insumos naturales y por el cuidado del medio ambiente. Para llevar a cabo el presente trabajo de investigación, se analizó factores internos y externos de la industria. Además, se desarrollaron estrategias para lograr impulsar nuestro proyecto. Para finalizar, se mostrará el plan financiero para sustentar la viabilidad de nuestro negocio. / This project is called "Naturessa", which is a company that offers the public the alternative of acquiring an organic toothpaste made with natural supplies and with an eco-friendly packaging; this with the purpose of providing benefits to the health of the consumer and collaborating with the care of the environment. For the realization of this project, two uncertainties that exist in the oral health market were identified. On the one hand, we identify that traditional toothpastes contain supplies that are harmful to human health, since they cause problems such as irritations, bone conditions, cancer, among others. Likewise, consumers are not informed of these evils. On the other hand, traditional toothpastes are causing environmental pollution, since they are produced with microplastics that work as agents to remove tooth dirt and are contained in plastic containers. Naturessa is aimed at men and women of socioeconomic level A and B of zone 7 of the city of Lima, which includes the districts of Miraflores, San Isidro, San Borja, Surco and La Molina. In addition, these people worry about using natural inputs and caring for the environment. To carry out this research work, internal and external factors of the industry were analyzed. In addition, strategies were developed to boost our project. Finally, the financial plan will be shown to support the viability of our business. / Trabajo de investigación

Development of new carbon hybrid materials for Li+ and Na+ ion batteries applications / Développement de nouveaux matériaux carbonés hybrides pour des applications dans les batteries Li+ et Na+ ion

Pana, Cristina 09 February 2018 (has links)
Au cours des dernières années, de nombreuses recherches se sont concentrées sur les batteries afin de satisfaire leur demande croissante pour de nombreuses applications. Les matériaux hybrides métal/carbone ont fait l'objet d'une grande attention en tant qu'anodes pour les batteries ioniques Li et Na en raison de leur capacité plus élevée par rapport aux anodes graphite/carbone dur. Cependant, l'expansion de la taille des NPs métalliques et la forte capacité irréversible pendant le 1ercycle sont les principaux inconvénients à surmonter et représentent l'objectif principal de cette thèse. Trois types d'hybrides ont été étudiés (C@Sn et C@SiO2pour les LIBs, et C@Sb pour les NIBs) et des voies de synthèse originales ont été développées qui ont permis d'obtenir des matériaux avec des NPs petites et homogènes distribuées dans le réseau de carbone. Plusieurs paramètres expérimentaux ont été optimisés, conduisant à une vaste palette de matériaux avec des porosités, des structures et des granulométries différentes. La température et la charge de particules se sont avérées être les principaux paramètres affectant la porosité et la taille des particules ainsi que les performances électrochimiques. L'augmentation de la température et de la charge de NPs ont conduit à une porosité plus faible qui a permis de diminuer la capacité irréversible et d'améliorer la capacité réversible. En même temps, le cycle à long terme a été affecté négativement en raison de la formation de particules non confinées et agglomérées. Un compromis entre la charge de carbone/porosité/structure a été déterminé pour chaque système et les mécanismes électrochimiques traités sur la base d'analyses post-mortem. / During the last years a lot of research has been focused on batteries to satisfy their increasing demand for a broad application. Metal-based/carbon hybrid materials received great attention as anodes for Li and Na ion batteries due to their higher capacity compared to graphite/hard carbons anodes. However, the metal particle size expansion and the high irreversible capacity during cycling are the main inconvenients to be overcome and represent the main goal of this thesis. Three type of hybrids were studied(C@Sn and C@SiO2for LIBs, and C@Sb for NIBs) and original synthesis pathways were developed which allowed to obtain materials with small and homogeneous distributed particles in the carbon network. Several experimental parameters were tuned leading to a large pallet of materials exhibiting different porosities, structures and particle size/distribution. The temperature and the particle loading were found to be the main parameters affecting the porosity and the particle size and further the electrochemical performances. The increase of both temperature and particle loading lead to smaller porosity which successfully allowed to diminish the irreversible capacity and to improve the reversible capacity. In the same time, the long-term cycling was negatively affected due to the formation of un-confined and agglomerated particles. The extent of particle agglomeration and consequently of capacity fading was found to depend on the type of metal and synthesis route. A compromise between the carbon loading/porosity/structure was determined for each system and the electrochemical mechanisms addressed based on post-mortem analyses.

Almibag

Casaverde Portella, Johan Fabrizio, Wong Mendoza, Joan Sebasti, Rojas Cisneros, Edson Michelle, Huanuco Figueroa, Sandra Carolina, Zamudio Rotger, Bruno 07 July 2020 (has links)
En la actualidad la contaminación ha aumentado considerablemente, el mar se ha llenado de desperdicios y muchos animales se han visto perjudicados. Varios medios han informado que dicha situación va a ir aumentando si no se realizan cambios. Por lo tanto los diferentes países han coincidido en que se deben tomar medidas. En Perú por su parte se aprobó la ley N° 30884 que regula el plástico de un solo uso así como diferentes tipos de envases descartables. Debido a esto se creó Almibag que son la venta de bolsas biodegradables en base a almidón de yuca. Estas bolsas resultan beneficiosas para las personas debido a que ayudan al medio ambiente ya que se demoran en degradarse de 2 a 3 años y a su vez son fuertes para cargar los productos que sea necesario. Almibag se dedica a la tercerización, se ha conseguido personas que fabriquen este producto en bruto y así nosotros podemos personalizarlo y venderlo en diferentes lugares como son supermercados, tiendas, minimarkets, etc. Se espera que las ganancias aumenten año tras año con el fin de lograr rentabilidad para la empresa. Es importante considerar que Almibag al no ser fabricantes directos, deben poner empeño en sus acciones de marketing, como lo es las estrategias de las 4p así también los planes estratégicos internos e internos y por último cuáles van ser sus estrategias financieras como ya antes se mencionó ya que es importante generar rentabilidad. / Today, pollution has increased considerably, the sea has been filled with waste and many animals have been harmed. Various media have reported that this situation will increase if changes are not made. Therefore, the different countries have agreed that measures must be taken. In Peru, meanwhile, Law No. 30884 was approved, which regulates single-use plastic as well as different types of disposable packaging. Because of this Almibag was created, which is the sale of biodegradable bags based on cassava starch. These bags are beneficial for people because they help the environment since they take 2 to 3 years to degrade and are also strong enough to carry the products that are necessary. Almibag is dedicated to outsourcing, we have recruited people to manufacture this raw product and so we can customize it and sell it in different places such as supermarkets, stores, minimarkets, etc. Profits are expected to increase year after year in order to achieve profitability for the company. It is important to consider that Almibag, as they are not the direct manufacturers, must put effort into their marketing actions, as is the 4p strategies as well as the internal and external strategic plans and finally what will be their financial strategies as mentioned before because this is essential to be profitable. / Trabajo de investigación

The Eco-Smart Can V2.0

Nanto, Darack B 01 May 2019 (has links) (PDF)
On a scorching summer day in 2015, a campus maintenance worker was observed emptying a trash bin. Upon closer observation, it was noted that the bin was not full; in fact, it was less than one third full. There were other bins that were full and needed to be emptied urgently. It was confusing and problematic to see that bins that needed more attention were not prioritized. After extended research, it was found that maintenance operates on daily routes to pick up trash at designated times, regardless of the level of trash in the bins. Therefore, to tackle this issue, the author decided to use the Internet of Things (IoT) to develop a prototype that will optimize trash collection and reduce costs of waste management and pollution; this device is named the Eco-Smart Can.

Influence of supercritical carbon dioxide (scco2) dyeing parameters on color fastness of polyester fabric dyed with disperse dye : A study towards minimizing the energy consumption of polyester (pet) fabric dyeing with azo disperse dye

Das, Tapas January 2023 (has links)
Amid growing environmental concern and continuous depletion of natural resources (such as water), the textile industry is constantly searching for sustainable production process. Traditional dyeing processes, notorious for their enormous water consumption, have led society to search alternative dyeing method. Super critical carbon dioxide (scCO2), emerging as a promising dyeing medium shows a potential solution to mitigate water utilization, consequently raising sustainable textile material wet processing. As this innovative technology characterize by its waterless nature, no effluents are generated and conserves enormous amount of water, energy while increasing productivity. Although it has attained commercial focus in polyester fabric dyeing, the imperative remains to reduce energy demand during dyeing process including commercially available dyes. As a result, the optimization of dyeing conditions assumes crucial importance, broadening the feasibility of these eco-friendly dyeing techniques. The objective of this thesis work is to find out the optimum dyeing conditions of polyester (PET) fabric dyeing with an azo disperse dye (Corangar orange PE3330) utilizing supercritical carbon dioxide (scCO2) as a dyeing medium. The investigation aims to unravel the dynamic correlation withing scCO2 dyeing conditions and dye performance. To conduct this study, comprehensive methodology employing a statistical design of two-level three-factor (23) full factorial design was adopted. The studied factors enclose temperature, pressure and dyeing durations, enclosing ranges of 80-1200C, 10-25Mpa and 1-2 hours respectively. Dye concentration was kept constant at 0.2%. The study looks for individual conditions of studied parameters and their impacts on color strength (K/S). Moreover, an analysis of color fastness attributes, comprising washing, sublimation, rubbing and extraction, is carried out. The statistical analysis shows that the prominence of pressure and temperature as the principal factors in scCO2 dyeing medium. Differential scanning calorimetry (DSC) analysis proves the negligible morphological transition in PET fabric following dyeing (crystallinity % for dyed and undyed fabric is 28.80 and 28.42% respectively). Findings also shows that comparable color properties to the traditional standard of PET fabric can be obtained by adapting dyeing pressure (20Mpa) and time (1 hour) while keeping the dyeing temperature (1200C). The findings concluded that satisfactory color strength (K/S) and color fastness related to the standard scCO2 dyeing process can be obtain with reduced energy and pressure. The outcome of this study subtle the relationship between temperature, pressure, and time towards color strength (K/S) and color fastness properties. Nonetheless, investigation of this study remained confined to laboratory-scale and for the purpose to upscale this finding for commercial use, it is crucial to carry out rigorous industrial trials.

Risks and drivers of hybrid car adoption: A cross-cultural segmentation analysis

McLeay, F., Yoganathan, Vignesh, Osburg, V-S., Pandit, A. 04 April 2018 (has links)
Yes / Throughout the developed world, consumers are increasingly being encouraged to adopt cleaner, more eco-friendly behaviours. However, hybrid car adoption remains low, which impedes the move towards a lower carbon economy. In this paper, we examine the risks and drivers of hybrid car purchases, drawing on consumer behaviour and cultural dimensions theory to account for the heterogeneous, segmented nature of the market. As risk perceptions differ across cultures, and in order to address the lack of cross cultural research on eco-friendly cars, we focus on Australian, South Korean, and Japanese consumers. Based on a survey of 817 respondents we examine how five types of risk (social, psychological, time, financial, and network externalities) and three factors that drive purchasing behaviour (product advantages, product attractiveness, and product superiority) influence consumers perceptions of hybrid cars. Four segments of consumers are identified (pessimists, realists, optimists, and casualists) that also vary according to their environmental self-image, and underlying cultural values. Our results extend theory by incorporating self-image and cultural dimension theories into a multi-country analysis of the risks and drivers of hybrid car adoption. Our findings have practical implications in terms of marketing strategies and potential policy interventions aimed at mitigating risk perceptions and promoting the factors that drive hybrid car adoption.
