Não existe uma listagem precisa de quantas plantas alimentícias existem no mundo, mas existem estudos e estimativas que variam de doze mil e quinhentas a setenta e cinco mil espécies. Porem a diversidade utilizada atualmente se apresenta ínfima frente a tal diversidade existente, levando-nos a discutir a forma como a espécie humana vem se alimentando. As plantas que apresentam potencial alimentar, mas que por diversos motivos não vem a ser consumidas de forma ampla pela população recebem a denominação de Plantas alimentícias não convencionais (PANC). Diversas plantas são encaradas como daninhas, sendo a elas atribuída uma reputação pouco apreciável, porem tal relação se dá em boa parte por desconhecimento de suas utilidades e potencialidades econômicas. Espécies que normalmente se desenvolvem sem tratos culturais e que apresentam fácil dispersão estando presentes em vários tipos de ambientes alem do agrícola, como por exemplo, o meio urbano, podem ser consideradas Plantas Espontâneas. Este estudo realizou o levantamento das espécies de plantas alimentícias não convencionais de ocorrência espontânea em uma área de Sistema Agroflorestal localizado dentro do campus da Universidade estadual Paulista (UNESP) no município de Rio Claro, interior do estado de São Paulo. Das trinta e seis espécies de PANC espontâneas identificadas, vinte e oito espécies (77,7%) apresentaram-se comestíveis, revelando o potencial alimentar deste grupo

Currently there are two car models that use electricity in their propulsion systems, the electric vehicle and the hybrid electric vehicle. The electric vehicles are classified as vehicles that use electric motors in their propulsion system and batteries as a power source, on the other hand, the hybrid vehicles are classified as vehicles that use both electric motors and internal combustion engines in their propulsion system, using both batteries and líquid fuels as a power source. The main goal of this work is to analyze the characteristics of electric and hybrid electric vehicles and demonstrate the unfeasibility of the electric vehicle in the current economic, political, energetic and environmental brazilian scenario, for this purpose it was realized a study about the current brazilian situation regarding to electricity generation, current conservation status of road network, lack of electrical infrastructure for charging batteries, national lithium reserves, environmental characteristics, tax incentives, economic scenario, oil market and political positioning related to the implantation of electric or hybrid electric fleets in nacional territory. The operational characteristics analysis of electric and hybrid electric vehicles in this current scenario leads to the conclusion that currently a growth of electric vehicles fleets on a national scale is totally impractical in the Brazil, Thus, the introduction of green vehicles probably will occur primarily with hybrid electric models, motivated mainly due the bigger autonomy of this models compared to electric models, lower cost of hybrid electric models compared to electric models, factors related to the lack of recharging infrastructure and also factors related to political positioning

Recently technological resources have been used to facilitate the execution of several laboral activists. In this project it will be shown a device, which will help workers in healthy area to develop their activities, decreasing the wear of themselves and making the patient transfer to bed more efficient. Furthermore, this work will show a device project to transfer patients with motor restrictions. The focus of this device is to avoid fatigue and injury of workers, which will help the patient to decrease their discomfort and the risk of injury. In addition, the device will be developed and designed to be easy to use and with reduced fabric cost to facilitate the access of institutions as rest homes and the APAE
