Abstract: the study of preservation process of the assai pulp through the application of hurdle technology was done by the application of the following preservation factors: reduction of ph at about 3.5 by the addition of 0.5% w/w of citric acid, thermal treatment (82.5°c for 1 min), reduction of the water activity by the addition of sucrose (10, 25 and 40% w/w) and addition of potassium sorbate (0.075 and 0.15% w/w). a full factorial experimental design was used in the elaboration of the formulations of the product, that were stored at 25°c in the absence of light for 5 months. the formulations 1, 2 and 8 were discarded sensorially before 3 months storage. besides, the formulations 2 (40%w/w of sucrose), 4 (40%w/w of sucrose and 0.15%w/w of potassium sorbate) and 5 (25%w/w of sucrose and 0.075%w/w of potassium sorbate) showed a good overall acceptability shelf-life time of 5 months.
Isotermas de dessor??o de filé de bonito (Sarda sarda) desidratado osmoticamente e defumado
Hubinger, Míriam D.;Vivanco-Pezantes, David;Kurozawa, Louise E.;Sobral, Paulo J. A.;
Revista Brasileira de Engenharia Agrícola e Ambiental , 2009, DOI: 10.1590/S1415-43662009000300012
Abstract: the main objetive of this work was to obtain the desorption isotherms of atlantic bonito (sarda sarda) fillets, previously subjected to an immersion impregnation process with nacl solutions and smoked in liquid smoke. the isotherms were obtained at four temperatures (5, 25, 40 and 60 oc), using the static method with saturated salt solutions. the experimental data were fitted to four models (linearized bet, gab, henderson and modified oswin). the results showed that a type ii sigmoidal isotherm, with gab equation, gave the best fit. the isosteric heat of desorption was also calculated and a simple empirical equation has been proposed to represent this heat, as a function of equilibrium moisture content.
Displasia ectodérmica hipohidrótica: Presentación de un caso
Miranda Díaz,Belkis Tamara; Rodríguez Casas,Míriam Marlen;
Revista M??dica Electr?3nica , 2009,
Abstract: the christ-siemens-touraine syndrome or hypohydrotic ectodermal dysplasia, is the most frequent form of the so called ectodermal dysplasias; a congenital character syndrome in which one or several components of the ectoderm are affected, without presenting a progressive course. the hypohydrotic ectodermal dysplasia is an hereditary familiar syndrome, transmitted as a recessive characteristic linked to x, affecting 90 % of the males. the most common form of the ectodermal dysplasia is the hypohydrotic one, characterized by the triad hypohydrosis, hypotrichosis and hypodoncia. another finding was a fascia characterized by frontal convection, depression of the nasal bridge and proquelia for absence of teeth. we found otorhinolaryngologic manifestations, allergic disorders and from light to moderated nail dystrophy. the patient arrived to our consultation with previous familiar antecedents of father affected by hypohydrotic ectodermal dysplasia, third of four siblings (two brothers and a sister), only a nephew, son of his sister, with hypohydrotic ectodermal dysplasia. he told about antecedents of frequent respiratory infections, xerosis and blisters in oral mucosa. when we carried out the physical examination we found: sun dermatosis, stomatitis, characteristic facial features of prominent forehead and chin, everted and thick lips, and also big earlobes. the physical dermatologic examination showed smooth skin, dry and wrinkly around the eyes, giving an aspect of premature aging. the hypotrichosis is partial in the scalp, eyebrows, beard, armpits and pubis. the physical oral examination showed gums inflammation, stomatitis and abnormal dental development.

Abstract: El síndrome de Christ-Siemens-Touraine o Displasia Ectodérmica Hipohidrótica, constituye la forma más frecuente de las llamadas displasias ectodérmicas: síndromes de carácter congénito, en los que se ven afectados uno o varios componentes derivados del ectodermo y que no presentan un curso progresivo. La displasia ectodérmica hipohidrótica se trata de un síndrome heredo familiar, transmitido como un rasgo recesivo ligado a X, que afecta en el 90% de los casos a los varones. La forma más comúnmente encontrada de displasia ectodérmica es el tipo hipohidrótico, caracterizada por la triada hipohidrosis, hipotricosis e hipodoncia. Una fascie caracterizada por abombamiento frontal, con depresión de tercio medio, hundimiento de puente nasal y proquelia por la ausencia de dientes son otros hallazgos. Se encuentran manifestaciones visuales, otorrinolaringológicas, desórdenes alérgicos, infecciones respiratorias y distrofia de las u as de leve a moderada. El paciente llegó a nuestra consulta con APF de padre afectado de Displasia Ectodérmica Hipohidrótica, tercero de cuatro hermanos (dos varones y una mujer no afectados), único sobrino con Displasia Ectodérmica Hipohidrótica, hijo de su hermana. Refirió antecedentes de infecciones respiratorias frecuentes, xerosis y vesicoampollas en mucosa oral. Al examen físico encontramos: dermatosis solares, estomatitis, rasgos faciales característicos de frente y mentón prominente, nariz de punta fina, mejillas hundidas, labios gruesos y evertidos, así como pabellones auriculares grandes. Al examen físico dermatológico presentó la piel lisa, seca y arrugada alrededor de los ojos, dando un aspecto de envejecimiento prematuro. La hipotricosis es parcial en cuero cabelludo, cejas, barba, axilas y pubis. Al examen físico estomatológico presentaba inflamación de las encías, estomatitis y desarrollo dentario anormal.

Ensaio: Avalia??o e Políticas Públicas em Educa??o , 2004, DOI: 10.1590/S0104-40362004000400007
Abstract: this article has the intention of study in the social representations that the teachers of the lower school of the colégio de aplica??o build over the democratic public school having as its research field the colégio de aplica??o of the federal university of rio de janeiro and the colégio de aplica??o of the state university of rio de janeiro. the main objective of the present study was to capture the dynamics of the representation construction of a democratic school, and at the same time to search for its historical and ideological motivations and the changes it suffered along the time; and also to understand the values, the rules, the behavior, the symbols and the resistances of the lower school teachers towards the democratization process of the contemporary pedagogical practices. the lower school teachers representations about the democratic school follow the present education project that is being developed at the caps or the one that has been already applied in another historical moment. this project in itself becomes the reference of the public, democratic and the quality school. in the crossing of the speeches were born the analytical categories: alterity, power and resistance. it was concluded that the democratic education could not be based on any notion of non-history and transcendental truth or authority. the school democracy is a tension process born by the power relationship within the institution. among the investigated group, were encountered representations that maintain the caps' original selective and elitization function, and therefore reinforce the social exclusion; other representations defend a differentiated formation in line with the cap student original social class and a third group that reinforces the possibility of the implementation of an educational project that advances in the direction of the introduction and recognition of the lower class students into the school activities and daily life.
Paradoxos da identidade: a política de orienta??o sexual no século XX
Adelman, Míriam;
Revista de Sociologia e Política , 2000, DOI: 10.1590/S0104-44782000000100009
Abstract: this article works from the perspective of social constructivism on sexuality with the aim of discussing the emergence of modern "sexual identities". i identify, on the one hand, the "invention" of homosexuality (and, consequently, of heterosexuality) in the discursive production of victorian society. on the other hand, i discuss the form in which this new category becomes the basis of a political strife that vindicates sexual diversity, focusing mainly on the evolution of sexual orientation politics in 20th. century north american society.
Vis?es sobre o trabalho em transforma??o

Abstract: in this article, the changes that have marked our societies after the crisis and restructuring of capitalism since the last decades of the 20th century are seen as having had great impact over labor relations, disarraying the relations that have shaped the welfare state and reordering them under market regulation. considering the central role assigned to work in our societies, it becomes relevant to discuss different interpretations of emergent phenomena in the world of labor - from approaches that point to "the end of work" to those that argue its sustained centrality - reflecting over their social implications. it is underlined that the speedy process of current technological diffusion has been making labor relations precarious, broadening insecurities and vulnerabilities, and becoming a crucial source of social inequality. the article is closed with reflections over the development of the world of labor, postulating a critical view regarding extreme positions about the subject and underlining the unfavorable repercussions entailed by the changes under way, in order to advert to undesired social outcomes.
Vis es sobre o trabalho em transforma o
Toni Míriam de
Sociologias , 2003,
Abstract: No artigo, considera-se que as transforma es que têm marcado nossas sociedades a partir da crise e reestrutura o do capitalismo desde as últimas décadas do século XX repercutem fortemente sobre as rela es de trabalho, desordenando as rela es que conformaram o Estado de Bem-Estar Social e reordenando-as sob a égide da regula o pelo mercado. Considerando o papel central atribuído ao trabalho em nossas sociedades, torna-se relevante discutir as diferentes interpreta es sobre os fen menos emergentes no mundo do trabalho - desde enfoques que apontam para o "fim do trabalho" até os que defendem a permanência da centralidade do trabalho -, refletindo sobre suas implica es sociais. Ressalta-se que o processo veloz de difus o tecnológica em voga vem precarizando as rela es de trabalho, ampliando inseguran as e vulnerabilidades e sendo fonte crucial de desigualdade social. Encerra-se o artigo com reflex es sobre o evolver do mundo do trabalho, propondo um olhar crítico a posi es extremadas sobre o tema e ressaltando as repercuss es desfavoráveis acarretadas pelas muta es em curso, no sentido de advertir sobre conseqüências sociais n o desejadas.
