Plan de emprendimiento en base a cascos plegables en la ciudad de Lima 2019

Hoy en día, nuestra sociedad está contemplando diversos problemas dentro del manejo de tiempo, salud, tráfico y medio ambiente. Es por ello, que muchas personas han dejado de utilizar el medio de transporte convencional (autos, buses, taxis, etc.)  y han comenzado a utilizar un medio de transporte alternativo que beneficia tanto a la salud del usuario como a la protección del medio ambiente. Estos medios de transporte son en su mayoría bicicletas, las cuales han tenido un aumento en su demanda de un 25% respecto al año anterior. Este incremento en la demanda está influenciado por la gran cantidad de millennials que buscan proteger su salud y el medio ambiente. Sin embargo, la mayoría de estos usuarios no utilizan implementos de seguridad. A pesar de que su uso sólo es obligatorio en ciertos distritos los usuarios de igual manera no lo utilizan, en especial el casco que es el implemento de seguridad más importante. Después de realizar entrevistas a diferentes usuarios logramos identificar cuáles eran los factores clave por lo cual no utilizaban casco como el precio y la comodidad. Con esta información, desarrollamos un casco que puede reducir su tamaño para poder llevarlo dentro de tu mochila o cartera a un precio que se encuentra dentro del rango de la competencia. Es por ello, que con el presente trabajo buscaremos validar si nuestro producto será rentable a través de validaciones, concierge y ventas para demostrar que nuestro producto si es deseado por el usuario.Today, our society is contemplating various problems within the management of time, health, traffic and the environment. That is why many people have stopped using the conventional means of transport (cars, buses, taxis, etc.) and have begun to use an alternative means of transport that benefits both the health of the user and the protection of the environment. . These means of transport are mostly bicycles, which have had an increase in demand of 25% over the previous year. This increase in demand is influenced by the large number of millennials who seek to protect their health and the environment. However, most of these users do not use security implements. Although its use is only mandatory in certain districts, users do not use it in the same way, especially the helmet that is the most important safety device. After conducting interviews with different users, we were able to identify what were the key factors, so they did not use a helmet such as price and comfort. With this information, we develop a helmet that can reduce its size to be able to carry it inside your backpack or purse at a price that is within the range of the competition. That is why, with the present work we will seek to validate if our product will be profitable through validations, concierge and sales to demonstrate that our product is desired by the user.Trabajo de investigació

The diverse meteorology of Jezero crater over the first 250 sols of Perseverance on Mars

NASA’s Perseverance rover’s Mars Environmental Dynamics Analyzer is collecting data at Jezero crater, characterizing the physical processes in the lowest layer of the Martian atmosphere. Here we present measurements from the instrument’s first 250 sols of operation, revealing a spatially and temporally variable meteorology at Jezero. We find that temperature measurements at four heights capture the response of the atmospheric surface layer to multiple phenomena. We observe the transition from a stable night-time thermal inversion to a daytime, highly turbulent convective regime, with large vertical thermal gradients. Measurement of multiple daily optical depths suggests aerosol concentrations are higher in the morning than in the afternoon. Measured wind patterns are driven mainly by local topography, with a small contribution from regional winds. Daily and seasonal variability of relative humidity shows a complex hydrologic cycle. These observations suggest that changes in some local surface properties, such as surface albedo and thermal inertia, play an influential role. On a larger scale, surface pressure measurements show typical signatures of gravity waves and baroclinic eddies in a part of the seasonal cycle previously characterized as low wave activity. These observations, both combined and simultaneous, unveil the diversity of processes driving change on today’s Martian surface at Jezero crater.This work has been funded by the Spanish Ministry of Economy and Competitiveness, through the projects no.
