ABSTRACT

Lacan vai dizer, sem muito argumentar, que Freud chegara mesmo a repudiar o termo "nonsense", termo este que nos é apresentado pelo próprio Freud como o que mais amplamente caracteriza o chiste, em especial, o Gedankenwitz. Verificaremos de que maneira Lacan vai lidar com essa questão. O que ficará de fora, na abordagem lacaniana, de acordo com nossas suspeitas, é a função do prazer tal como Freud a sustenta, a saber, do ponto de vista "econômico". Lacan, por sua vez, não deixa de ressaltar a importância da questão do prazer no chiste, prazer este tido por ele como autêntico, ou seja, o prazer próprio do uso do significante. Em outras palavras, Lacan faz do chiste um significante. O que se pretende esclarecer, com efeito, é a diferença de perspectivas em relação à função do prazer no chiste.


Lacan will say, without much argument, that Freud had even repudiate the nonsense word, a term that has been presented by Freud as the most widely characterized the Witz, especially Gedankenwitz. We will check how Lacan will deal with this issue. What will be left out in the Lacanian approach, according to our suspicions, it is the function of pleasure as Freud maintains, namely in terms of "economic". Lacan, in turn, does not fail to emphasize the importance of the issue of pleasure in the Witz, he had this pleasure to be authentic, the pleasure of using their own significant. In other words, Lacan makes a Witz one significant. What is intended to clarify, in fact, is the difference in perspectives on the role of pleasure in the Witz.

ABSTRACT

To achieve proper recontouring of anterior and posterior teeth, to obtain optimal morphology during enamel stripping, it is important to be aware of dental anatomy. This study aimed at evaluating crown dimensions and proximal enamel thickness in a sample of 40 extracted sound, human, mandibular, second bicuspids (20 right and 20 left). Mesiodistal, cervico-occlusal and buccolingual crown dimensions were measured using a digital caliper, accurate to 0.01 mm. Teeth were embedded in acrylic resin and cut along their long axes through the proximal surfaces to obtain 0.7 mm-thick central sections. Enamel thickness on the cut sections was measured using a perfilometer. Comparative analyses were carried out using the Student's-t test (α= 5 percent). The mean mesiodistal crown widths for right and left teeth were 7.79 mm (± 0.47) and 7.70 mm (± 0.51), respectively. Mean cervico-occlusal heights ranged from 8.31 mm (± 0.75) on the right to 8.38 mm (± 0.85) on the left teeth. The mean values for the buccolingual dimension were 8.67 mm (± 0.70) on the right and 8.65 mm (± 0.54) on the left teeth. The mean enamel thickness on the mesial surfaces ranged from 1.35 mm (± 0.22) to 1.40 mm (± 0.17), on the left and right sides, respectively. On the distal surfaces, the corresponding values were 1.44 mm (± 0.21) and 1.46 mm (± 0.12). No significant differences were found between measurements for right and left teeth. However, enamel thickness was significantly greater on the distal surfaces, compared with the mesial surfaces.

ABSTRACT

As características do leite de búfalas da raça Murrah foram investigadas, utilizando-se como parâmetros a composição, com ênfase no perfil de ácidos graxos. As análises de composição foram realizadas por meio de equipamento Bentley 2000®, o perfil de ácidos graxos por cromatografia gasosa e a qualidade da fração lipídica foi avaliada, utilizando-se os índices nutricionais, através do perfil de ácidos graxos. A composição do leite de búfala sofreu influência da fase de lactação, com aumento de teor de gordura e redução da lactos e no terço final da lactação. No total de ácidos graxos presentes no leite de búfala, as maiores concentrações de ácidos saturados foram encontrados no início da lactação. No final da lactação houve aumento da concentração de ácidos monoinsaturados. Considerando-se o perfil lipídico, a melhor qualidade nutricional foi observada na fase final de lactação.


The buffalo milk quality was evaluated based on the milk composition parameter, giving the emphasis to theprofile of fatty acids at the early and the late lactation phases. The composition analysis was carried out bythe equipment Bentley 2000®. The fatty acids profile was analyzed by means of gaseous chromatography. Thequality of the lipid fraction was evaluated based on the data of fatty acids composition, using nutritional index.The milk composition was affected by lactation phase, considering the fat increase, and lactose reductionat third part of late lactation. In the total of fatty acid contents in milk, the highest rates of saturated acidconcentrations were found in the early lactation. The increased monounsaturated acid concentration wasobserved in the late lactation phase. Taking into account the lipid profile, the best nutritional quality wasobserved at the final phase of lactation.

ABSTRACT

Este trabalho foi realizado com o objetivo de avaliar as características físico-químicas, sensoriais e microbiológicas de bebidas lácteas elaboradas com leite de búfala e diferentes níveis de iogurte e soro lácteo. Foram desenvolvidas cinco formulações à base de leite de búfala, soro de queijo tipo frescal e iogurte. Os tratamentos foram: T1=10 por cento leite, 10 por cento soro e 80 por cento iogurte; T2=10 por cento leite, 20 por cento soro e 70 por cento iogurte; T3=10 por cento leite, 30 por cento soro e 60 por cento iogurte; T4=10 por cento leite, 40 por cento soro e 50 por cento iogurte; e T5=10 por cento leite, 50 por cento soro e 40 por cento iogurte. Para o leite e soro, foram determinadas acidez titulável (°D), densidade a 15°C, gordura, EST e ESD. As bebidas lácteas foram avaliadas quanto aos parâmetros: pH, acidez titulável, gordura, proteína, viscosidade, cor (CIEL*a*b*), teste de aceitação sensorial com escala hedônica de cinco pontos, ordenação da preferência, enumeração de coliformes a 35 e 45°C e contagem de microrganismos mesófilos aeróbios. Os resultados obtidos, submetidos ao teste de ANOVA e teste de médias com nível de significância a 5 por cento, revelaram que os níveis de soro influenciaram os valores de pH, acidez, gordura, proteína, viscosidade e L* das bebidas lácteas, enquanto as coordenadas de cromaticidade a* e b* não sofreram influência. As formulações com 10 e 20 por cento de soro foram as mais aceitas no teste de aceitação sensorial, bem como na preferência pelos julgadores.


This research was carried out to evaluate the physical-chemical, microbiological and sensorial characteristics of dairy beverages elaborated with buffalo milk and different levels of yoghurt and whey. Five formulations were developed based on buffalo's milk, cheese whey and yogurt. The treatments were: T1=10 percent milk, 10 percent whey and 80 percent yoghurt; T2=10 percent milk, 20 percent whey and 70 percent yoghurt; T3=10 percent milk, 30 percent whey and 60 percent yoghurt; T4=10 percent milk, 40 percent whey and 50 percent yoghurt; T5=10 percent milk, 50 percent whey and 40 percent yoghurt. It was determined the acidity (°D), density at 15°C, fat, total solids (TS) and non-fat solids (SNF). The dairy beverage was evaluated on: pH, titratable acidity, percentages of fat and protein, viscosity, color (CIEL*a*b*), sensorial acceptance test with hedonic scale of five points and preference ordination, coliforms enumeration s at 35°C and 45°C, count of mesophilic aerobic microorganisms. The obtained results, submitted to ANOVA and Tukey Test with significance level of 5 percent revealed that the whey rates of the dairy beverage influenced pH, acidity, fat, protein, viscosity, L*, and water activity, while the chromaticity coordinates a* and b* did not suffer influence. The formularizations with 10 percent and 20 percent whey were the most accepted in the sensorial acceptance test, as well as in the preference of the judges.
