Delicadezas: ensino e escritura em Caio Fernando Abreu e Roland Barthes
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-graduação em Literatura, Florianópolis, 2011Esta tese trata de modos de subjetivação por meio da escrita. Subjetivação do escritor e do educador, disseminados em outras vozes. O educador, quando colocado em estado de desequilíbrio, é remetido a um espaço crítico plural como acesso a um meio de produção da escrita. De modo análogo, configura-se um plano de composição de onde rumores e murmúrios criam o imaginário afetivo entre a escritura de Caio Fernando Abreu e Roland Barthes. O jogo da escritura, portanto, liga o educador ao escritor. A escritura, neste caso, se esquiva de ser uma mediação ou uma obliteração, mas emerge como oxigênio no espaço da aula. A escrita como arte é provada como uma condição e uma necessidade

Palestra acessibilidade na comunicação
No full textA Escola Nacional de Administração Pública (Enap) realizou, nesta quarta-feira (22) de 2017, a palestra Acessibilidade na Comunicação. A atividade foi ministrada pelo coordenador-geral de Acessibilidade da Secretaria Especial dos Direitos da Pessoa com Deficiência, do Ministério da Justiça e Cidadania, Rodrigo Abreu de Freitas Machado. Na abertura do evento, o presidente da Enap, Francisco Gaetani, ressaltou a importância da inclusão como agenda governamental: “Temos que construir uma sociedade pluralista e inclusiva. Se não houver iniciativa de incluir as pessoas com deficiência, muitas delas serão excluídas da sociedade”. Em sua apresentação, Rodrigo Machado abordou os temas Deficiência, o conceito social; O que é e para que serve a acessibilidade?; O que são barreiras?; O que a lei diz a respeito?; Recursos de acessibilidade na comunicação; Dicas de comunicação inclusiva; Acessibilidade em sítios eletrônicos; e E-mails acessíveis. Rodrigo Machado explicou que deficiência é o resultado da interação entre pessoas com impedimentos e as barreiras que impedem a plena e efetiva participação dessas pessoas na sociedade em igualdade de oportunidades com as demais pessoas. “A sociedade em que vivemos exclui muita gente que não se encaixa no ‘padrão’. Porém, todos nós somos diferentes, não existem homens e mulheres padrão”, disse. Ele ressaltou também que todas as pessoas se beneficiam da acessibilidade – não só aquelas com algum tipo de deficiência – mas que algumas dependem dela para a equiparação de oportunidades. “Acessibilidade é eliminar barreiras. Quando se eliminam as barreiras, a tendência é que se elimine a deficiência”, explicou.31 p.ComunicaçãoComunicação PúblicaSobre o palestrante – Rodrigo Abreu de Freitas Machado, servidor público, é arquiteto e urbanista formado pela Universidade de Brasília.

Development of encapsulated olive leaf extracts as innovative natural and functional food ingredients
No full textThe increasing consumer concern and demand in the last decades for foods with natural ingredients and enhanced nutritional and health-promoting properties has pushed the research in the fields of nutrition and food technology in order to find, characterize, formulate and incorporate bioactive compounds into common foods or nutraceuticals. Some of the most used food bioactives are plant phytochemicals like polyphenols present in most plants as secondary metabolites. Olive biophenols, present in most parts of the plant and found in high concentrations in the leaves, are widely recognized for their bioactive properties. Thus, olive leaves, traditionally considered as a by-product, are an abundant source of olive phenolic compounds that can be recovered and further exploited as functional ingredients in food and nutraceuticals.
However, the intrinsic chemical characteristics of these and other phytochemicals compounds makes its direct use in foods very challenging. In this context, food microencapsulation has been progressively implemented to partially or totally tackle these technological and sensorial issues associated to their incorporation into foods. The large variety of bioactives (pure compounds, phenolic-rich extracts) and carriers, the specific objective of the encapsulation and the large complexity of food matrices are the reasons for the wide research and development approaches in this field. Due to the different nature of the encapsulation techniques, specific investigations on their related critical parameters and optimization of the encapsulation process and performance are needed.
The investigations carried out in this work aimed to better understand the use of phenolic extracts from olive leaves by studying its chemical stability and developing encapsulated ingredients with encapsulation techniques of different nature with the potential to be used in real food matrices.
Firstly, a phenolic extract from olive leaves rich in oleuropein, a well defined compound with significant health-promoting properties, was characterised in terms of thermal stability at varying pH conditions of the phenolic content, profile and radical scavenging properties, by implementing a kinetic model and also structural characterization using flurescence spectroscopy.The thermal degradation of the major component, oleuropein, followed first-order kinetics and was high at lowest pH values (pH = 2), while verbascoside appeared to be more labile at pH 6. Oleuropein hydrolysis products resulted in an increasing hydroxytyrosol concentration, that followed zero-order kinetics. These changes were also detected by fluorescence spectroscopy. On the other hand, no remarkable changes in total phenolic content and radical scavenging activity were observed.
Freeze-drying was studied as a method to encapsulate olive leaf bioactives in amorphous dry carbohydrate matrices. The effect of the carrier formulation and ratio bioactive:carrier on the encapsulation efficiency, the thermal, physical and structural properties of freeze-dried microencapsulated powders was assessed by using a response surface modellig approach. Also, the impact of these factors on the chemical stability of bioactive compounds was studied. Maltodextrin and trehalose were chosen as encapsulating materials as representatives of high and low molecular weight carbohydrates with good glass forming properties for encapsulation purposes. The increasing concentration of maltodextrin enhanced the encapsulation of both total phenolics and oleuropein up to an almost total retention when maltodextrin was used alone, which could be directly observed thanks to fluorescence imaging. Color and thermal properties of the microencapsulated powders depended on the maltodextrin-trehalose ratio and a plasticizing effect of olive leaf extract was also observed, especially in the glassy powders containing maltodextrin. The storage study of unencapsulated and microencapsulated olive leaf extract powders under different physical states revealed that at least for 7 weeks, the chemical stability and antioxidant properties of the bioactives were not affected.
Liposomal encapsulation of olive bioactives was investigated, first in model phospholipid membranes by evaluating the effects of oleuropein on membrane thermotropic behavior (differential scanning calorimetry) and ordering and fluidity (fluorescence polarization) in systems with passively encapsulated oleuropein (i.e., added after formation of liposomes) compared to actively encapsulated oleuropein (i.e., encapsulated during formation of liposomes). Also, the antioxidant capacity of oleuropein to inhibit lipid peroxidation. was evaluated under two types of oxidation induction. A potential food ingredient was developed by encapsulating the olive leaf extract in commercial soy phosphatidylcholine, and characterized for its morphological, physical and functional properties in model and real systems (commercial soft drink). Oleuropein and verbascoside were encapsulated with a mean efficiency of 34% and 75%, which indicated that optimization this process can be further investigated to improve the encapsulation. However, liposome encapsulation was effective for a delay of oleuropein degradation at low pH (i.e., pH 2.0), and for the maintenance of oleuropein stability over long periods at refrigeration temperatures and at different pHs. This thus shows that this lipid encapsulation indeed provides a suitable carrier in food systems, such as beverages.
Finally, the antioxidant performance of olive leaf extract and other standard and plant extracts was assessed in more challenging and real food processing conditions like those commonly employed during melt-extrusion processing/encapsulation, as opposed to classical liquid antioxidant assays. A simple and novel approach has been proposed to estimate the antioxidant performance under controlled conditions using a lab-scale extruder by implementing a solid-state adaption of the crocin-bleaching liquid assay, based on the bleaching of saffron crocins

The Construction of A Hero: Rodrígo Díaz De Vivar Through His Epic Adventures In Las Mocedades De Rodrigo And El Cantar De Mio Cid
No full textThe construction of a hero: Rodrígo Díaz de Vivar through his epic adventures in Las Mocedades de Rodrigo and El Cantar de Mio Cid Montserrat Gonzalez California State Polytechnic University, Pomona Las Mocedades de Rodrigo is a late epic poem, composed during the Middle Ages narrating the fictional adventures of Rodrigo Díaz de Vivar, El Cid, a long-standing hero in Spanish Nationalistic discourses. Its codex, found in the National Library in Paris, does not portray the mature hero that will forge the legend on El Cantar de Mio Cid but instead describes him at a young stage of his life, what enables the poet to display Rodrigo's ancestors and the conflicts his family faced when he was a young boy. Las Mocedades depicts Rodrigo as an arrogant and rude twelve-year old kid who did not had the respect of the king, the soldiers or the community, thus questioning the very foundations of the construction of the literary myth, as portrayed in El Poema de Mio Cid. While Mocedades de Rodrigo presents the early life of Rodrigo Diaz de Vivar, el Cantar de Mio Cid portrays El Cid as the brave mature leader that late nineteenth century nationalistic critics, such as Menendez Pelayo have praised. El Cid is depicted as a loyal vassal who battles his enemies on behalf of his king as well as for his own honor. Critics of Mocedades de Rodrigo such as V.A Hubert claim that such poem is an imitation of El Cantar de Mio Cid which affects the perception and reputation of this iconic idol, thus availing for a more contemporaneous reading of the poem attuned to nowadays sensibilities. Thus, it is important to compare and understand both poems in order for us to ponder the different renderings of the character, and the impact those might have as contemporary readings
