ABSTRACT This article discusses the imbrications of the contemporary technological context with consumption and advertising in the Brazilian scenario. For this, we start with a theoretical review on the accelerated expansion of digital technology, which, on the one hand, initially brought democratic and inclusive promises, with broad access and sharing of information; on the other hand, over time, it had harmful effects, especially in the social, political, and ideological spheres. Consumption is centrally part of this discussion, since the possession and manipulation of data and algorithms occur by a few powerful global private companies, which have their economic model based on advertising. Finally, we will present market actions that exemplify the peripheral position of the country’s consumer-citizens in this debate. scenario technology hand promises information time effects social political spheres discussion companies Finally countrys country s consumercitizens consumer citizens debate

RESUMO Este artigo discute as imbricações do contexto tecnológico contemporâneo com o consumo e a comunicação publicitária no cenário brasileiro. Para isso, partimos de uma revisão teórica sobre a expansão acelerada da tecnologia digital, que, se, por um lado, trouxe, inicialmente, promessas democráticas e inclusivas, com o amplo acesso e compartilhamento de informações; por outro, ao longo do tempo, provocou efeitos nocivos, sobretudo em âmbito social, político e ideológico. O consumo insere-se nessa discussão de forma central, já que a posse e a manipulação de dados e algoritmos ocorrem por poucas e poderosas empresas privadas globais, que têm seu modelo econômico baseado na publicidade. Finalmente, apresentaremos ações mercadológicas que exemplificam a posição periférica dos consumidores-cidadãos do país neste debate. brasileiro isso digital se lado trouxe inicialmente inclusivas informações outro tempo nocivos social ideológico inserese insere central globais publicidade Finalmente consumidorescidadãos consumidores cidadãos debate

Resumo O contexto da pandemia da Covid-19 provocou impactos em diferentes áreas, inclusive no cenário midiático, na publicidade e no consumo. Nesse triplo entroncamento estão as chamadas lives – entendidas e delimitadas aqui como transmissões ao vivo de conteúdos musicais por plataformas digitais. Este artigo tem por objetivo jogar luz sobre este novo fenômeno, procurando compreendê-lo na sua complexidade, não apenas do ponto de vista conceitual, mas também em categorizações aplicadas em articulação com as marcas.

Abstract The meanings of lives in the context of the pandemic: from escapism and philanthropy to identity logics The context of the Covid-19 pandemic had impacts in different areas, including the media scene, advertising and consumption. At this triple junction are the so-called lives – understood and delimited here as live transmissions of musical content via digital platforms. This paper aims to shed light on this new phenomenon, seeking to understand it in its complexity, not only from a conceptual point of view, but also in terms of categorizations applied in conjunction with brands. From an interdisciplinary bibliographic review and an anthroposemiotic analysis of 36 musical lives produced and transmitted in Brazil, we found emotional (escapist and empathic), energetic (philanthropic and interactive) and logical (identity and community) lives, projecting different media and advertising environments for the brands.

ABSTRACT This study aimed to evaluate the performance and ingestive behavior of growing goats grazing on Tanzania guinea grass and fed diets containing 40% carnauba or tucum fruits. Twenty-one male castrated goats were distributed into three groups, one exclusively on pasture and the other two on pasture and fed diet supplemented at the level of 1.5% body weight (BW) in a completely randomized design. The intake of the supplements was obtained by difference between the amount supplied and the leftovers, with weighing performed every seven days, while pasture intake was determined using titanium dioxide (TiO2) as external indicator. Ingestive behavior was evaluated for three days. The supplement containing carnauba fruit resulted in a greater intake of neutral detergent fiber (0.137 kg NDF/day), with a reduction of 8.61% in the pasture dry matter (DM) intake of goats. Associated with the intake of pasture nutrients, the tucum fruit diet met the protein (0.103 kg CP/day) and energetic (0.547 kg TDN/day) requirements of goats with intake set at 0.124 kg CP/day and 0.572 kg TDN/day, with higher weight gain (0.111 kg/day) and larger loin eye area (12.76 cm2). The supplementation with fruits influenced the grazing behavior of goats, increasing the idle time by 1 h in relation to animals not supplemented. The supplementation of growing goats grazing on Tanzania guinea grass pasture with a diet containing 40% tucum fruit, in the proportion of 1.5% BW, did not meet the nutritional requirements for gain of 150 g/day; however, it met requirements for maintenance and average gain of 111 g/day. Energy supplementation reduces the grazing time of goats; thus, it is necessary to consider the level and formulation of supplements, with the possibility of increasing the stocking rate and productivity per unit area.

Abstract A novel trypsin inhibitor of protease (CqTI) was purified from Chenopodium quinoa seeds. The optimal extracting solvent was 0.1M NaCl pH 6.8 (p < 0.05). The extraction time of 5h and 90 °C was optimum for the recovery of the trypsin inhibitor from C. quinoa seeds. The purification occurred in gel-filtration and reverse phase chromatography. CqTI presented active against commercial bovine trypsin and chymotrypsin and had a specific activity of 5,033.00 (TIU/mg), which was purified to 333.5-fold. The extent of purification was determined by SDS-PAGE. CqTI had an apparent molecular weight of approximately 12KDa and two bands in reduced conditions as determined by Tricine-SDS-PAGE. MALDI-TOF showed two peaks in 4,246.5 and 7,908.18m/z. CqTI presented high levels of essential amino acids. N-terminal amino acid sequence of this protein did not show similarity to any known protease inhibitor. Its activity was stable over a pH range (2-12), temperatures range (20-100 °C) and reducing agents.

Avaliou-se o fluxo de biomassa em capim-tanzânia sob lotação rotativa com quatro níveis de suplementação concentrada, com período de ocupação de três dias e descanso de 21 dias, em delineamento de parcelas subdivididas, de modo que as parcelas foram os níveis de suplementação (0,0; 0,6; 1,2 e 1,8% do PV) e as subparcelas, os ciclos de pastejo (quatro), com três repetições (piquetes amostrais). Não houve efeito dos níveis de suplementação e dos ciclos de pastejo sobre a relação entre as taxas de lâmina foliar (TAlF) das folhas 1 e 2 recentemente expandidas, com média de 0,69. A suplementação e os ciclos de pastejo tiveram efeito quadrático sobre a taxa de alongamento foliar, cujas estimativas foram de 5,04; 4,95 (ponto de mínimo estimado) e 5,7 cm/perfilho·dia nos níveis de 0,0; 0,46 e 1,8% de suplementação, respectivamente. A taxa de alongamento das hastes e a altura do pseudocolmo não foram afetadas pelos níveis de suplementação. As taxas de senescência foliar anterior, posterior e total não foram afetadas pelos níveis de suplementação nem pelos ciclos de pastejo. Não houve efeito dos níveis de suplementação nem dos ciclos de pastejo sobre o filocrono. A taxa de crescimento da cultura e a taxa de acúmulo da cultura não foram afetadas pelos níveis de suplementação nem pelos ciclos de pastejo. O índice de área foliar residual foi estimado em 2,00 e de 2,72 nos níveis de suplementação de 0,0 e 1,8% PV. Não houve diferença na densidade populacional de perfilhos entre os níveis de suplementação, porém, entre ciclos, observou-se que o ciclo 4 foi superior ao 2 e semelhante aos demais. Os componentes do fluxo de biomassa do capim-tanzânia são pouco afetados pelos níveis de suplementação.

The biomass flow of Panicum maximum cv. Tanzania under intermittent stocking with four concentrate supplementation levels, with three grazing periods and 21 rest periods was evaluated. A split plot design, with supplementation level (0.0, 0.6, 1.2 and 1.8% of live weight) and grazing cycles as sub-parcels, with three replicates (paddocks) by treatment was used. There was no effect between supplementation levels and grazing cycles on the leaves 1 and 2 TAlF ratio, averaging 0.69. There was a square effect of the supplementation level on the leaf elongation rate, estimating 5.04, 4.95 (estimated minimum point) and 5.70 cm/tiller × day to the levels of 0.0, 0.46 and 1.8% LW, respectively. No effect of the supplementation levels on the culm elongation rate and culm height was observed. The supplementation levels and grazing cycles did not affect the senescence rate of leaves remaining after grazing, of the new emerged leaves, the total senescence rate. No effect of the supplementation levels and grazing cycles on the phylochron was observed. There was no effect of the supplementation levels and grazing cycles on the herbage growth and herbage accumulation rates. A residual leaf area index of 2.00 and 2.72 was estimated for supplementation levels of 0.0 and 1.8% LW. No effects of the supplementation levels on the tiller population density were observed. In relation to the cycles, cycle 4 was higher than cycle 2 and similar to the others. The biomass flows of tanzania grass are little affected by the supplementation levels.
