Desenvolvimento de bioblendas poliméricas a partir de gelatina bovina e de tilápia com amido de milho

The natural raw materials acquired special importance beside the mineral raw materials with the need for using alternative sources to oil, because they can be used to produce biopolymers. Gelatin, produced from the denaturation of collagen, and starch, an abundant polysaccharide in various plants, are examples of biopolymers which have several technological applications, especially in films. The objective of this work is to produce polymeric bioblends with gelatin and corn starch using two types of gelatin: commercial bovine gelatin and gelatin produced from mechanically separated flesh of tilapia (Oreochromis niloticus). For the extraction of tilapia gelatin 3 distinct pretreatments, followed by extraction in distilled water under heating were performed. The properties of gelatin extracted were similar to bovine gelatin, and the differences can be explained by the difference in extraction processes and sources. Blends of commercial gelatin and starch were produced in an internal mixer from a Haake torque rheometer, to study the behavior of the gelatin mixture with starch, thus, the same compositions were processed by twin screw extrusion, to define the mixing parameters. Subsequently, the extrusion of blends of tilapia gelatin and corn starch was carried out in the same twin screw extruder. The physico-chemical, rheological and morphological properties of the blends with thermoplastic starch and gelatin were studied. It was found that various properties vary linearly with increasing concentration of the components. The blends produced are immiscible, and among the two gelatins, tilapia gelatin showed a better interfacial adhesion with the corn starch. Regarding the morphology, gelatins formed the dispersed phase in all compositions studied, even in compositions rich in starch. Can be concluded that the procedure for tilapia gelatin extraction is feasible and advantageous, and the increasing in its scale to a reactor of 30 liters is possible, with a satisfactory yield. The bioblends of bovine gelatin/corn starch and tilapia gelatin/corn starch were successfully produced, and the processing conditions were appropriate

Corpo e gestualidade :o jogo da capoeira e os jogos do conhecimento

In the direction of questing a sociology that considers the flesh dimension of the existence, that favors to think the body while place of the production of the knowledge, our itinerary of research is characterized for the reflection on the gesture of the body as power of life and production of knowledge, recognizing the precision of the gesture as a privileged breach of comment of the collective life, of the projection and registration of the culture, of the symbolic, of the sensitivity. Our problematic can be meet in the possibility to enhance an open and sensible rationality, tattooed in the body and accessible for the gestures, that its materialized in the relations of the human being with the other and the world, in singular and collective relations. Therefore, the gesture, constructed in the intention the experience of the body, can tell us about the human being, the society and the culture, therefore the sensed of the gestures is constructed from the established and recognized mutual actions for the citizens. It is in this field of production of the knowledge, of knowing of the meat that we direct our perception, in the challenge to immerge into the intention of the gesture in the capoeira game. Of the methodological point of view, for the analysis of the gestures of the capoeira, therefore, of the body as knowledge power, we consider registers of images as well as narratives registers of the universe of the capoeira, as well as my experience of more than seven years in the group of capoeira cordão de ouro1. A epistemological exercise has as support a qualitative research where parts of the quantity of images of the investigated group, as well as interviews, daily registers in of field and over all my experience of life next to the group and to the capoeira, in intention to recognize symbols tattooed in the body and for it produced in the inter subjectivists relations. We search therefore, to evidence sensible and meanings drawn for the gesture and evidenced by the look of the researcher. We presents as objectives of this inquiry to nuance ribbings around of the social and cultural elements in the production of the knowledge of the body, of the gesture, weaveeed for the sensible rationality

O Corpo do grupo corpo: os movimentos das obras Benguelê, Lecuona e Onqotô

In this research, we invite to reflection by a phenomenological gaze on the body, through the description of some works of contemporary Brazilian dance company Grupo Corpo. This Company was chosen intentionally to give us elements in their creations to interrogate the understanding of the body and sensitive. Thus, as we launch issues in this dissertation: that body dance in Grupo Corpo? And as we can see, a phenomenological approach, an understanding of the body and sensitive works in that company? Building on this, the works are to be questioned Benguelê (1998/2003), Lecuona (2004) and Onqotô (2005). It is intended, through these works, coreological approaching the discourse of philosophical discourse and give movement to phenomenological thought of Maurice Merleau-Ponty, in special the sensitive, flesh of the body, the investment in the sensory world as a merger, calling the know body and its power to take chances, to incorporate the world, language, culture, create and choose. Thus, these openings is where thought enters this research. This consistency, we used the phenomenological attitude of Maurice Merleau-Ponty as a methodological approach, since in their study the philosopher takes a look expressive on the body, forming a sensitive language that is expressed in the movements, which deepens the arguments of the Phenomenology a new arrangement for knowledge as a result of our experience in the lived world. The reflections presented here aim to take us to the amazement, the unthinking, whom many still impose epistemological challenges, including understanding the body of knowledge and sensitive

Análise bromatológica de carnes antes e após o processamento para obtenção de charque

The process of salting and drying in the sun is used to preserve meat since the beginning of civilization. There is evidence that this preservation technique has arisen in Egypt, between 4,000 and 5,000 years ago. In our country, according to literature, was the first industrial product that gave the appearance of beef jerky, beef being produced, where about 70% to 75% of the muscle is composed of water, where it will be around 45% as a final product, according to the law in his article RIISPOA No. 432 provides that the jerky should contain no more than this amount of moisture in the muscular portion, or more than 15% of total ash with tolerance of up to 5% variation . Besides this parameter, proteins, lipids, ash, and minerals were analyzed in samples before and after the manufacturing process to know the content of these nutrients. Since these are considered important in product quality, thus the concentration in these samples, respectively, in the flesh Front (CD and CHD) before and after the manufacturing process for humidity were respectively 75.28% and 47.38% , the protein was 14.17 and 22.20 g / 100 g sample, 6.360 and 4.251 of lipids g/100g of the sample, and the ashes 0.974 9.144 g/100g sample, minerals like calcium and 4.074 30 , 06 ppm, sódio0, 055 and 5.401 g / L, sodium chloride, 0.139 and 13.74 g / L, potassium 237.5 and 166.8 ppm, 1.721 and 3.295 ppm iron, 0.143 and 0.135 ppm phosphorus, zinc and 4.690 6.905 ppm; magnésio14, 63 e13, 75 ppm manganese .017 e0, 007ppm, copper 0.057 and 0.039 ppm in the case of needle-type meat (CPA and CHPA), 68.04% and 44.17%, protein 13 , 72, and 24.42 g/100g of sample, 1.137 in the ash and 12.68 g / 100g of sample, and the minerals calcium 17.11 and 12.89 ppm; sódio0, 123 and 4.871 g / L, sodium chloride 0.312 and 12.39 g / L, potassium 305.3 and 182.1 ppm; ferro1, 817 and 1.513 ppm, 0.273 and 0.139 ppm phosphorus, zinc 6.305 and 4.783 ppm, 27.95 and 15.85 ppm magnesium, manganese and 0.025 0.011 ppm, 0.057 and 0.143 ppm copper and chromium 0.014 and 0.068 ppm

Análises bromatológicas e fitoquímicas de frutos de Licania tomentosa (Benth) FRITSCH

This study conducted chemical analyzes of the fruits of Licania tomentosa Benth belonging to the Chrysobalanaceae family, order and superorder Rosiflorae Rosales. Samples were collected in February 2011 in the city of Natal - RN. The fruits were separated into peel, pulp and seed, and the samples were analyzed on moisture and ash by thermogravimetric methods, reducing and total sugars, lipids by Soxhlet extraction, minerals by ICP / OES and other analyzes by physical measurements of the fruit. The fruits for the analysis of determination of flavonoids and phenolic compounds were dried at 40 ° C and ground. For the analyzes to determine the content of phenolics and flavonols was used spectroscopy in the visible region, and also performed the characterization of ethanol extracts by high performance liquid chromatography and test for antioxidant activity hydroethanolic extracts. The results obtained are about 83.9% of the fruits have a length between 4.0 to 6.0 cm with respect to the diameter of the fruit about 97.4% of the fruits have a diameter between 2.0 - 4, 0 cm, mean weight of 36.14 g (7.86), the bark showed 60.5 (1.5)% relative humidity, the flesh 72.3 (0.9) and 44.4 seeds (0.4 )%, the bark showed 0.22 (0.00)% ash, the pulp 1.41 (0.01)% and the seed 1.18 (0.01)%, the bark showed 3.73 (0, 09) mg lipids / 100 g sample of the pulp 0.40 (0.04) and the seed 0.05 (0.00). With respect to reducing sugars and total gave the results, 16.23 (0.23) g/100g and 20.70 (0.24) g/100g. The fruit is presented with a good source of nutrients especially carbohydrates and lipids. The analysis for determining the antioxidant activity tests were performed reducing power and antioxidant capacity, the antioxidant capacity of hydroethanolic extracts of peel and pulp showed similar results, with higher concentrations however hydroethanolic bark extract. Regarding the content of phenolics and flavonoids hidroetanílico bark extract showed higher concentration values. The characterization of the extracts by high performance liquid chromatography identified the following compounds by retention time indicated by the race of the standards: galic acid, kaempferol and kaempferol derivatives. Considering the results of the fruit Licania tomentosa Benth may be an alternative food by analysis of their nutritional content and has substances with antioxidant action

Um retrato do marginal brasileiro mediante o trabalho do ator com as personagens de Plínio Marcos em “Navalha na carne"

This thesis presented is to research the actor's work in the construction of physical actions, according to the methodology developed by Constantin Stanislavski in his analysis of dramatic action, called "method of physical action", applied to questions of scenic representation of the Brazilian marginal, according to the look "cruel" and realistic / naturalistic Plinio Marcos playwright. Based on the circumstances given by Pliniano universe, the intention is to contribute to the reflection on the actor's work on the scene with the marginal characters in "Razor in the Flesh", highlighting some important aspects, to assist in the construction of this fictional world. You want to create conditions for the formation of an actor that leverages the scene the contradictions and conflicts of this work. The research aims from the theoretical and practical study as a methodological hypothesis, producing critical reflection from the creative process of the agent with the realization of a scenic experiment focused on psychophysical technique of this Russian pedagogue. Thus, we intend to have a look at the method of physical actions focusing on his last great contribution to the work, especially the procedure of active analysis by doing a reading from "Razor in the Flesh" through this creative scenic exercise, extending the studies concerning the actor's art. This research is a general explanation about the trajectory of Stanislavski to his encounter with the physical action, while, highlights the inconsistencies of understanding of his work around the world. Stanislavski initially developed the "method" having as a backdrop, the realist aesthetic - a dialogue relationship between reality and the scene - through a style which creates a theatrical reality, and consequently, artistic, not literally naturalistic way through an integral mimicry. That is, the representation of work in realistic theater aesthetics should be developed in order to create a theatrical reality. Stanislavski believes that theater is convention, since the actor's work on himself should encourage this second nature, scenic.
