Abstract: The goal of this study was to evaluate the process of salting and dry salting of fillets in pacu (P. mesopotamicus), from cultivation in cages. Fillet with skin were salted at a rate of 40% of salt in relation of the initial weight, for a period of 10 days. After processing, were evaluated for microbiological and centesimal composition of fillets subjected to salting and determining the concentration of sodium chloride (NaCl) and calculation of income. The centesimal composition were evaluated the protein, ether extract, moisture and ash of the raw material fresh and processed products by salting. The microbiological analysis included the determination of coliforms at 45 ° C, Salmonella and Staphylococcus coagulase positive. The pacus subjected to umided and dry salting were within quality control standards established by the legislation. The content of umided, protein and lipids and chlorides showed differences (P < 0.05) between the processes of salt. However both forms can be used for the development of technological processes of low investment by encouraging new options for fish consumption. O objetivo do presente estudo foi avaliar o processo da salga seca e salga úmida em filés de pacu (P. mesopotamicus), provenientes do cultivo em tanques-rede. Os filés com pele foram salgados na propor o de 40% de sal em rela o ao peso inicial, por um período de 10 dias. Após processamento, foram avaliados os parametros microbiológicos e de composi o centesimal dos filés submetidos a salga, bem como a determina o da concentra o de cloreto de sódio (NaCl) e cálculo de rendimento. Quanto à composi o centesimal foram avaliados os teores de proteína, extrato etéreo, umidade e matéria mineral da matéria-prima in natura e nos produtos processados por salga. As análises microbiológicas compreenderam a determina o de Coliformes a 45°C, Salmonella sp e Staphylococcus coagulase positiva. Os pacus submetidos a salga úmida e seca mantiveram-se dentro dos padr es microbiológicos estabelecidos pela legisla o. Os teores de umidade, proteína e lipídios e cloretos apresentaram diferen as (P < 0,05) entre os processos de salga. No entanto, ambas as formas podem ser utilizadas para o desenvolvimento de processos tecnológicos de baixo investimento incentivando novas op es para o consumo de pescado.

Abstract: The aim of this study was to evaluate the zootechnical performance and chemical composition of jundia juveniles Rhandia voulezi fed with mash, pelletized and extruded diets and cultivated in cages. One hundred and fifty fish were distributed in fifteen cages (0.20 m3), arranged in cages (5m3), in the hydroelectric plant of Governador José Richa, in Igua u River (Paraná-Brazil). The fish were fed five times a day, with mash, pelletized and extruded diets, containing 30% of protein and 3250 Kcal/kg of digestible energy/kg. At the end of 60 days, significant differences (p<0.05) were observed on fish performance. The fish that were fed with pelletized diet, presented higher average of final weight (44.08g), final length (16.51cm) and weight gain (36.65g). The different processes did not influence fish survival. The averages of protein and mineral matter of carcass chemical composition did not differ statistically (p<0.05), while the values of humidity and lipideos presented differences among treatments. The highest average of lipideos (8.59%) was observed in peletized diet. The mash diet provided fish with lower lipideo (5.45%) and higher humidity (75.98%) rates. A pelleted diet is most suitable for juvenile catfish R. voulezi cultivation in cages.

Abstract: the aim of this study was to evaluate the requirement of crude protein (cp) and digestible energy (de) in piavu?u fingerlings (leporinus macrocephalus), for a period of 45 days. it was used 150 fingerlings with average weight of 0.40 ± 0.08g, distributed in 30 aquariums (30l) in a completely randomized design in a 3x 2 two-factorial scheme composed of three levels of crude protein (25, 30 and 35% of crude protein) and two levels of digestible energy (3,250 and 3,500 kcal of de/kg), totaling six diets and five replicates. the rations were given four times a day. weight gain linearly increased while feed conversion decreased, also in a linear fashion, according to crude protein levels. digestible energy only influenced weight gain whose best result was observed on animals fed diets containing 3,500 kcal digestyble energy. feed conversion was not affected by levels of digestible energy. a significant interaction occurred among cp and de levels for body composition in moisture, protein and lipids. levels of 35% of cp and 3,500 kcal of de provide better zootechnical results without affecting chemical composition of carcass of piavu?u fingerlings, so the suggested energy:protein ratio is 10 kcal/g cp.

Abstract: This study aimed to evaluate centesimal and microbiological parameters of mandi-pintado nuggets. With the results from the biometry of the fish, it was possible to observe that the species shows high main trunk yield and low content of visceral fat. After the utilization of the body proportions, the steaks were grounded and breaded, and the samples (in natura and nuggets) were separated to carry out centesimal and microbiological composition. The patties show 14,67% protein, 10,12% lipids, 16,43% carbohydrates, 2,70% mineral matter and 56,08% humidity, therefore fitting the patterns required by the Brazilian legislation. The microbiological results indicated that both the prime matter and the nuggets developed were ready for the processing and for the consumption. Therefore, mandi-pintado shows a high yeald of main trunk and a low content of visceral fat, besides from being an ideal raw for the development of nuggets that not only are a highly nutritious kind of food, but can also be easily prepared and have a high aggregated value. Este trabalho teve como objetivo avaliar os parametros centesimais e microbiológicos de nuggets de mandi-pintado. Com os resultados da biometria dos peixes pode-se observar que a espécie trabalhada apresenta alto rendimento de tronco limpo e baixo teor de gordura visceral. Após a realiza o das propor es corporais, os filés foram moídos e empanados, e as amostras (in natura e de nuggets) foram separadas para a realiza o da composi o centesimal e microbiológica. Os empanados apresentaram 14,67% de proteína, 10,12% de lipídios, 16,43% de carboidratos, 2,70% de matéria mineral e 56,08% de umidade, ou seja, dentro dos padr es exigidos pela legisla o brasileira. Os resultados microbiológicos indicaram que tanto a matéria prima quanto os nuggets desenvolvidos estavam aptos para o processamento e/ou consumo. Portanto, o mandi-pintado apresenta alto rendimento de tronco limpo e baixo teor de gordura visceral, além de ser uma matéria prima ideal para o desenvolvimento de nuggets, sendo este um alimento altamente nutritivo, de fácil preparo e com grande valor agregado.
O lugar do inconsciente ou sobre o inconsciente como lugar

Abstract: the basic idea in this paper involves a certain elaboration on the place of the unconscious, which corresponds, to a certain extent, to the bionian theory of binocular vision. in this theory, both the conscious and unconscious emerge in the psychic apparatus and they are much more constituted by their functions than by radically different structures. what is emphasized is much more the need of functions for both than the singularity and autonomy of the locations attributed to conscious and unconscious.

Abstract: Lira (1982) estudou um aspecto morfo-sintático do português -- a varia oo entre o sujeito pronominal e o sujeito zero. Este e um tópico de interesse nas línguas romanicas, pouco estudado até hoje, podemos exemplificar esta varia o com as seguintes senten as tiradas de grava es com falantes nativos do português: (1) Nos curtimo o namoro, mas legal mesmo: 0 Ia pro Parque Lage, 0 escrevia naquelas pedras nosso nome. Olha: 0 Ficou lá anos. Eu panhava lata de tinta do meu pai, $ levava dentro da bolsa e pincel, ai 0 pintava nosso nome lá. (MC 12 A/200) Cunha (1972:204) afirma que os pronomes sujeitos s o normalmente omitidos no português pois as desinências verbais bastam para indicar a pessoa a que se refere o predicado como também o número gramatical. Ele argumenta que a referência do sujeito é clara na flex o sujeito-verbo e que o uso do pronome é devido as seguintes raz es: ênfase; para opor duas pessoas diferentes; para diferenciar duas formas morfológicamente ambígüas. Quicoli (1976) em um enfoque gerativo-tansformacional discute a regra que ele chama de apagamento do sujeito pronominal em português. Ele argumenta que esta regra apaga somente pronomes sujeitos que s o redundantes, n o-enfáticos, n o-contrastivos. Entretanto uma análise da fala de 30 falantes - 15 minutos de cada falante - mostrou a seguinte situa o:
