O câncer é um conjunto de mais de 100 doenças que atinge todas as faixas etárias e sociais, independente do sexo. Acomete milhões de pessoas no mundo inteiro anualmente, sendo grande causadora de mortes. De maneira sucinta, é caracterizado pelo descontrole na proliferação de células anormais.Células tidas como normais em um organismo vivem, proliferam-se (dividem-se) e morrem de maneira controlada, sem danos para o mesmo. Entretanto, algumas células podem não obedecer ao controle, e por ora, dividem-se rápido e desordenadamente, devido, provavelmente, um defeito na maquinaria da mesma, acometendo o material genético. Com danos, a célula recorre ao sistema de reparo, o qual, por sua vez, pode não responder, e assim são originadas as células cancerosas. Esse crescimento exagerado leva consequentemente, a um maior número de células anormais, formando uma grande massa conhecida como tumor ou neoplasia maligna. Há dois tipos de tumores, o benigno e o maligno, sendo que a diferença entre eles está na agilidade do crescimento de suas células e também no deslocamento destas para outras partes do corpo. As células dos tumores benignos apresentam um crescimento lento quando comparado às células malignas, bem como não se deslocam do local de origem, e assim, não se propagam para outras partes do corpo. Já as células malignas apresentam características opostas às benignas; elas possuem a propriedade de se disseminar entre tecidos normais, formando tumores secundários. Tal processo de deslocamento de células cancerígenas de um determinado local para outro, implicando na formação de um novo tumor neste local, é conhecido como metástase. Aproximadamente 90% das mortes por câncer estão associadas à metástase, que mesmo com grandes avanços da ciência ainda é um processo pouco compreendido. Um fato importante na compreensão da metástase foi a divisão... (Resumo completo, clicar acesso eletrônico abaixo)

Este trabalho de Conclusão de Curso teve por finalidade investigar quais recursos interativos estarão disponíveis para o telejornalismo com a chegada da televisão digital e como esses recursos poderão ser usados como instrumentos para a ampliação do acesso à informação jornalística. Para tanto, foi feita uma reflexão sobre a produção de sentido e a prática discursiva, com ênfase nas alterações nos enunciados telejornalísticos no contexto da convergência midiática. Foram analisados dois telejornais, o “Jornal Globo News” e o “Jornal Hoje”, ambos da rede Globo. O referencial teórico-metodológico utilizado na leitura dos telejornais foi o da semiótica discursiva de linha francesa, com ênfase nas estratégias enunciativas dos conteúdos interativos, por considerar que estes referenciais sustentam o estudo dos processos de produção de sentido. O “Jornal Hoje” foi analisado enquanto produto que propõe nos conteúdos apresentados introduzir novas formas de relação de comunicação, privilegiando a perspectiva de interatividade por parte dos telespectadores. Isso porque os conteúdos remetem a audiência a interferir por meio de outra mídia, notadamente o computador, acessando o site do telejornal para poder participar. Assim, observa-se que se o conteúdo já se manifesta convergente, os suportes ainda não estão integrados, pelo menos nessa fase de transição. O “Jornal Globo News” foi analisado enquanto representante de um telejornal produzido e veiculado já na plataforma digital, o que não significa que possa ser considerado de imediato interativo. Foram ainda realizadas entrevistas com especialistas e pesquisadores da área temática da pesquisa, que contribuíram para o amadurecimento e crescimento da mesma. Por meio da análise dos objetos foi possível elaborar o “QUADRO DAS POTENCIALIDADES”, com os recursos interativos que poderão... (Resumo completo, clicar acesso eletrônico abaixo)

The collective purchases translate into new business strategies that so far are poorly studied, but they have modifyied considerably the forms of consumption through the consumers individualisation, which causes changes in society's routine. The analysis of the theme was performed by study cases of collective shopping places in the city of Campinas, country of the state of São Paulo, and on its influence in the metropolitan area, which intented to understand, through custumers interviews, the contradictions and peculiarities of this service that has increased each day more . For this purpose, the research methodology is focused on the consumer , that's because the process of productive change tied to forms of trade and distribution of goods have been transforming social values considerably, based increasingly on impulsive consumming . Thus, to understand how the electronic commerce and more specifically the collective shopping websites works, it's necessary to examine the forms of commerce and the consumer's behavior in order to explain the city organization and the contradictions of the geographic space

The search for more reliable security systems and information management of these systems is leading to a growing progress in new technologies investments that allow the implementation of equipment with a high level of reliability, but also have an agile and practical operation. This led people to turn increasingly looking for home automation systems, enterprise and industry for the automation and integration of their systems. The identification by radio frequency is very widespread today for ensuring both agility in handling records data, the reliability of their identification systems, which are increasingly advanced and less susceptible to fraud. Attached to this technology, the use of the database is always very important for the storage of information collected, the area where the MySQL platform is widely used. Using the open source Arduino platform for programming and manipulation of RFID module and LabVIEW software for the union of all these technologies and to develop a user-friendly interface, you can create a highly reliable access control and agility places a high turnover of people. This project aims to prove the advantages of using all these technologies working together, thus improving a flawed system effectively safety, cheaper and quicker

Innovation is widely recognized as important. In addition, in this context, innovation networks have gained importance in academic studies, since an organization alone, does not always have access to all necessary resources. Gobbo Junior and Olsson (2010) proposed a model of network innovation whereby the transformation networks would be the linking structures between exploration and exploitation networks. In this context, this paper presents two case studies of innovation networks, aiming to increase the understanding on transformation networks. The objective was to understand how they interconnect exploration and exploitation networks; the main actors present in this interface; and to evaluate whether these actors can act as agents, to accelerate the innovation process. It was possible to verify how the transformation networks interconnect exploration and exploitation, and identify the practices and their main actors.

The social networking sites have experienced a large and rapid growth in recent years and bring together millions of users in Brazil and worldwide. Such networks allow adding groups of people with common interests or relationships, enabling members of this group to communicate and exchange information. Some social networks have specific goals, for example, aggregate individuals with common interests and professional relationships. However, they all share information in some way, whether in the form of short texts, photos, videos, among others. Sharing information in files is also a growing activity on the Internet and can be done in various ways, from sending files via email to multiple contacts to make available areas shared by the same contacts. However, applications are not yet available to enable file sharing on Facebook, considered the premier social network today. Given the growing demand for sharing files over the Internet, and a large number of users familiar with the use of these integrated applications for Facebook there is a demand for applications that allow users to share files with their contacts in this social network. This study aims to investigate how users use Facebook, and their practices for file sharing. It is believed that the results will substantiate future projects to develop software for file sharing on Facebook. Due to the exploratory nature of this research, the choice was made for a survey to collect data, applied through the web. From the results obtained, was possible to observe a frequent use of file sharing, but no interest in paid services. Regarding Facebook, was possible to observe their extensive use in both the frequency of access as the hours spent, as well as an increased use of applications (games, quiz, etc.). The full set of results shows a favorable environment for developing applications for sharing files on Facebook.

The incipient but quickly expansion action on the Information and Communications Technologies (ICT) in Africa it is now just having different impact on these societies. One of these relates bear on how users are identified with these tools. Just like that we find individuals identify as bloggers, twitter followers or cyber activist. This contribution analyzes the Senegal’s fact where a successful use of social nets and web 2.0 tools experience (at least in repercussion) as social and political involvement while presidential elections in 2012 is tied to come back an identity: Cyber activist. Senegalese circumstance shows us how this identity has a personal and assertiveness dimension as well collective aspects of belonging to a community. One as much as the other, show us personal traits in contrast to previous beliefs, basically because it fuse and confuse virtual and reality. Due to dynamics from expanding technology, this identity is youthful and urban, but not only. This situation creates new dynamics at least in this affected group. For this reason, besides knowing emergence and evolution of this fact, it raises some of the involvement in social and political involvement from groups traditionally “invisible”. Beyond the new social behavior there are new changes in the rules of the game in order to start new social revolution.

This paper presents a study based on bibliographic research on LTE technology, chosen for the fourth generation of mobile phones, and the current status of implementation of 4G network in Brazil. The change in user behavior, which now uses data over the voice services, requires transmission networks to be increasingly robust and fast to enable the viewing of videos and use of other platforms that require internet connection. The retrospective of the development of mobile technologies, from 1G up to 4G that is currently used, shows the long road until it came to appliances and how the phone is used nowadays. Finally, the popularity of smartphones and hence the growing number of people with access to 4G networks, demanded new researchs for the development of future generations technologies in order to achieve the demand for speed enabling significant changes in user experience
