Práticas autobiográficas contemporâneas: as videografias de si

The popularization of the recording and reproduction technological apparatus cannot be defined merely as a technical expansion becausealong the way have appeared new narrative models and new ways for the expression of subjectivity. In this context, the self videographies are samples of new autobiographic practices in which the attempt at self- writing originates a new way of narration

Is T-mobile U.S. a good target for Comcast

Throughout 2015 there was a rumor in the market that the U.S.-based cable company, Comcast, could be expanding its segments to wireless. Despite offering cable TV, broadband and voice or even by operating theme parks, the company may be after T-Mobile U.S., a Deutsche Telekom subsidiary. Despite its failed attempt to buy Time-Warner Cable, it is expected that such a deal would occur for Comcast in a near future. Therefore, following the company strategic objectives, this thesis stresses the effects of acquiring T-Mobile U.S. in both, financial and strategic terms. With total synergies expected to achieve $5,130M and a total premium of$4,429M, such a deal would bring Comcast a net benefit of $5,632M. With a final price offer of$41.61 per share, the deal is recommended and should occur as soon as possible for the sake of the companies in the process.Ao longo de 2015 houve rumores no mercado de que a Comcast - empresa de cabo que opera nos Estados Unidos, poderia expandir a sua atividade em direção à indústria de telecomunicações móveis. Mesmo tendo segmentos como televisão por cabo, internet e voz, ou até mesmo parques de diversão temáticos, é possível que a empresa esteja inclinada a comprar a T-Mobile U.S., subsidiária americana da Deutsche Telekom. Depois de falhada a tentativa de compra da Time Warner Cable, é possível que a Comcast continue a procurar novos negócios dentro do mesmo segmento num futuro próximo. Assim, e de acordo com os objetivos estratégicos da empresa, esta tese pretende identificar quais as consequências de tal aquisição, em termos financeiros e estratégicos. Com sinergias totais estimadas em $5,130M e um prémio de$4,429M, a Comcast teria um benefício líquido de $5,632M. Com um preço final de$41.61 por ação, e tendo em conta os objetivos das duas empresas, o negócio é recomendando e deve até ocorrer nos próximos tempos para beneficio das partes envolvidas

Treatment of Industrial Effluents by the Microalgae Selenastrum Sp.

High consumption of clean water results in the generation of effluents that need to be treated and then safely discarded. Conventional methods for such treatment often do not offer an economical and sustainable result; therefore, new methods are needed, such as microalgae usage. Microalgae are unicellular beings capable of rapid adaptation, growth, and production of compounds of interest (pharmaceuticals, biofuels and others). This work aimed to study the effectiveness of the microalgae Selenastrum sp. in the treatment of effluents from the textile and pulp & paper industries, as well as the respective effects on its biomass development and accumulation of compounds. Four types of culture were carried out (for each type of effluent, a control, and a control with addition of glucose) lasting eight days, in duplicate, all with the addition of a standard culture medium and controlled abiotic factors. Analyses for compound removal (chemical oxygen demand and colour readings on the 200–800nm range) and biomass development (cell number, its dimensions, and weight) were performed four times during the process. At the end of the experiments, the average removal in effluents for COD and colour were 56.6% and 32.7% respectively, in addition to a biomass accumulation of 0.45 g/L. These results were comparable to those obtained for the control cultivation using glucose as a carbon source (70.0% COD removal and 0.51 g/L biomass accumulation). These results demonstrate the effectiveness of Selenastrum sp. in the treatment of industrial effluents, its resilience in stressful environments and the potential use of its accumulated compounds for biotechnological purposes. Keywords: microalgae, Selenastrum sp., industrial effluent, textile effluent, pulp effluent, effluent treatmen

Hobbes às avessas: o direito natural e a crise da democracia liberal

Nas décadas de 1920 e 1930, Carl Schmitt e Leo Strauss estabeleceram leiturasdistintas, e em parte complementares, do legado filosófico-político de Thomas Hobbes,especialmente da fundação moderna do direito natural e da conseqüente decadência doEstado em virtude dos fenômenos da neutralização e despolitização. Nosso objetivo, naretomada de suas críticas ao liberalismo, é delimitar uma possível gênese do pensamentoconservador a partir do legado intelectual desses autores. In the 1920s and 1930s, Carl Schmitt and Leo Strauss proposed twodistinct and in a way complementary lectures on the Thomas Hobbes’ political andphilosophical legacy, mainly on his modern foundation of natural right and eventuallyon the decadency of the state thanks to the phenomena of neutralizationand depoliticization. Taking into consideration the restatement of their criticismon liberalism, our aim here is to point out the genesis of a conservative thoughtout of the intellectual background established by those authors
