Flash Mob: da rede à praça

This work explores the flash mobs, which are flash mobilizations arranged by intent that involve a large number of people to do something together in a pre-arranged place. With the advent of 2.0 Internet, the sharing of information and the mobile virtual communication grown up and showed behavior of an individual person to meet for a common interest. Those affective relationships born in the social networks come to the urban space in a real-virtual space junction and the possibilities of that are unexplored yet. Studied by this work, the Y generation is the flash mob most popular public and uses those mobilizations to reinforce their fan identity and appreciation for a media product

Photoreactions of n-alkyl-3-nitrophenyl ethers with aromatic amines in SDS micelles: A laser flash photolysis study

The quenching of the triplet state of three n-alkyl 3-nitrophenyl ethers: 3-nitroanisol (3-NA), n-butyl 3-nitrophenyl ether (3-NB) and n-decyl 3-nitrophenyl ether (3-ND) by four aniline derivatives: aniline (AN), N,N-dimethylaniline (DMA), 2,4,6-trimethylaniline (TMA), and 4-tetradecylaniline (TDA), was investigated in aqueous micellar SDS solutions by laser flash photolysis. The transient absorption spectra for 3-NA and 3-NB reveal the formation of long-lived intermediate species in the presence of all four quenchers. while for 3-ND no amine-induced intermediates are observed. Comparison of the transient absorption spectra of the probe 3-NA in the presence of DMA in aqueous and micellar solutions shows that the intermediate species are favored by the SDS micelles. With DMA and TMA as quenchers the intermediates are suggested to be the ion radicals generated by single electron transfer from the amine to the probe in the triplet excited state. For the quenchers AN and TDA, the intermediates may be a-complexes. The relative quenching efficiencies generally decrease as the affinity of the quencher for the micellar phase (AN < DMA < TMA < TDA) increases and the mobility of the excited probe (3-NA > 2-NB) decreases.

Estudo de caso do programa Flash! Vidas : informação ou entretenimento?

O presente estudo de caso resulta de três meses de estágio no Grupo Cofina Media, onde foram desempenhadas funções jornalísticas na secção Vidas, do jornal Correio da Manhã (CM) e no programa televisivo Flash!Vidas, do canal Correio da Manhã TV (CMTV), desde o dia 2 de fevereiro até ao dia 2 de maio de 2015. Foi elaborado no âmbito do Mestrado em Jornalismo, no Instituto Politécnico de Lisboa, Escola Superior de Comunicação Social, e por objetivo a obtenção do grau de mestre no curso anteriormente referido. A análise tem como propósito perceber se as alegadas peças noticiosas transmitidas pelo programa televisivo Flash!Vidas, no canal Correio da Manhã TV, podem ser consideradas informação, entretenimento ou os dois géneros. É importante referir que o presente trabalho terá como base fundamental os valores-notícias estudados pelo teórico Nelson Traquina e o conceito de infotainment.

Simulador d'un processador amb Adobe Flash Player

Aquest Projecte pretén crear un simulador d’una màquina algorísmica, de caràcter didàctic amb Adobe Flash CS3 per a reproduir-lo amb Adobe Flash Lite Player, que és la versió per a dispositius mòbils. Simularà el comportament de la màquina algorísmica anomenada FEMTOPROC, que és capaç d’interpretar 4 instruccions molt senzilles: ADD, AND, NOT i JZ (jump if zero). Les diferents instruccions introduïdes que compondran un programa seran emmagatzemades en una memòria de 64 posicions de 8 bits cadascuna i hi haurà un Banc de Registres amb 8 registres de 8 bits, que es podrà inicialitzar al començament de la simulació.

Ultrahigh dose-rate FLASH irradiation increases the differential response between normal and tumor tissue in mice.

In vitro studies suggested that sub-millisecond pulses of radiation elicit less genomic instability than continuous, protracted irradiation at the same total dose. To determine the potential of ultrahigh dose-rate irradiation in radiotherapy, we investigated lung fibrogenesis in C57BL/6J mice exposed either to short pulses (≤ 500 ms) of radiation delivered at ultrahigh dose rate (≥ 40 Gy/s, FLASH) or to conventional dose-rate irradiation (≤ 0.03 Gy/s, CONV) in single doses. The growth of human HBCx-12A and HEp-2 tumor xenografts in nude mice and syngeneic TC-1 Luc(+) orthotopic lung tumors in C57BL/6J mice was monitored under similar radiation conditions. CONV (15 Gy) triggered lung fibrosis associated with activation of the TGF-β (transforming growth factor-β) cascade, whereas no complications developed after doses of FLASH below 20 Gy for more than 36 weeks after irradiation. FLASH irradiation also spared normal smooth muscle and epithelial cells from acute radiation-induced apoptosis, which could be reinduced by administration of systemic TNF-α (tumor necrosis factor-α) before irradiation. In contrast, FLASH was as efficient as CONV in the repression of tumor growth. Together, these results suggest that FLASH radiotherapy might allow complete eradication of lung tumors and reduce the occurrence and severity of early and late complications affecting normal tissue.

A limited area model intercomparison on the "Montserrat-2000" flash-flood event using statistical and deterministic methods

In the scope of the European project Hydroptimet, INTERREG IIIB-MEDOCC programme, limited area model (LAM) intercomparison of intense events that produced many damages to people and territory is performed. As the comparison is limited to single case studies, the work is not meant to provide a measure of the different models' skill, but to identify the key model factors useful to give a good forecast on such a kind of meteorological phenomena. This work focuses on the Spanish flash-flood event, also known as "Montserrat-2000" event. The study is performed using forecast data from seven operational LAMs, placed at partners' disposal via the Hydroptimet ftp site, and observed data from Catalonia rain gauge network. To improve the event analysis, satellite rainfall estimates have been also considered. For statistical evaluation of quantitative precipitation forecasts (QPFs), several non-parametric skill scores based on contingency tables have been used. Furthermore, for each model run it has been possible to identify Catalonia regions affected by misses and false alarms using contingency table elements. Moreover, the standard "eyeball" analysis of forecast and observed precipitation fields has been supported by the use of a state-of-the-art diagnostic method, the contiguous rain area (CRA) analysis. This method allows to quantify the spatial shift forecast error and to identify the error sources that affected each model forecasts. High-resolution modelling and domain size seem to have a key role for providing a skillful forecast. Further work is needed to support this statement, including verification using a wider observational data set.
