Processamento da carne do jacaré do pantanal (Caiman crocodilus yacare)

Trata-se de um estudo de algumas formas de processamento da carne de jacaré do pantanal como uma alternativa de consumo, de uma forma não convencional, da carne dessa espécie. Testa-se, ao mesmo tempo, a utilização de carne de cortes normalmente descartados tais como o tronco e os membros. Dessa forma relatam-se os seguintes processamentos: produtos de salsicharia não embutidos (tipo hambúrguer), carne em conserva (enlatado), carne curada e não cozida (defumada) e produto curado e cozido (tipo apresuntado). Avalia-se a qualidade dos produtos através da análise sensorial e mede-se estatisticamente o grau de sua aceitação.

Síntese e processamento de cerâmicas em forno de microondas doméstico

O uso de microondas no processamento e obtenção de materiais tem adquirido nos últimos anos crescente interesse por parte de diversas áreas do conhecimento como a química e a engenharia de materiais. Neste sentido, aparatos especialmente projetados têm começado a ser descritos na literatura como reatores e câmaras de processamento a microondas visando aplicação na pesquisa e na indústria. em particular o uso de fornos de microondas domésticos em atividades científicas tem se mostrado de interesse dado uma série de novas aplicações, simplicidade e baixo custo. O presente trabalho reporta um dispositivo desenvolvido a partir de um forno de microondas doméstico, capaz de efetuar sínteses e processamentos de sólidos mesmo quando os materiais envolvidos não possuem susceptibilidade as microondas. O novo dispositivo tem sido utilizado com sucesso na síntese de óxidos metálicos e, em especial na sinterização e ordenamento de redes cristalinas de filmes finos.

Distribuição vertical, danos e controle cultural de Stenoma catenifer Walsingham (Lepidoptera: Elachistidae) em pomar de abacate

Stenoma catenifer Walsingham is the major pest in avocado groves (Persea americana Mill.) in the Neotropical region. Management has been difficult for many reasons related to the reduced knowledge on its bioecology and the avocado growing systems. The goal of this work was to study the vertical distribution of S. catenifer in avocado plants, the gagging effect of infested fruit on its survival, and the losses caused. The experiments were conducted in a commercial grove located at the Sao Tomas de Aquino, State of Minas Gerais, Brazil, during the 2001/2002 and 2002/2003 growing season. S. catenifer was observed especially at the lower and central part of the plant, and the inner canopy was the least attacked in comparison with the north, south, east and west quadrants. These results may be important indicators for the use of am adequate sampling procedure. The highest percentage of attacked fruit had one to four larvae; in some cases up to eight individuals per fruit were found. The losses caused by the borer varied during the agricultural season, with figures close to 5% in a single evaluation, and the harvest loss may reach 27%. The bagging of infested fruit caused mortality of S. catenifer, as observed through the evaluation carried out four days later.

Influência da utilização da proteína texturizada de soja nas características sensoriais, químicas e funcionais e de processamento do fiambre de frango

This research was designed to study the effect of addition of 5, 10 e 15% of textured soy protein (TSP) on sensorial, chemical, and physical-chemical parameters of chicken loaf with ground meat. The sensorial properties were not affected by textured soy protein. The addition of textured soy protein in preparing chicken loaf increased the water absorption and holding capacity, and decreased the moisture and ether extract content, but did not increase the final product yield.

O processamento automático de línguas naturais enquanto engenharia do conhecimento linguístico

In this paper, we provide a brief description of the multidisciplinary domain of research called Natural Language Processing (NLP), which aims at enabling the computer to deal with natural languages. In accordance with this description, NLP is conceived as "human language engineering or technology". Therefore, NLP requires consistent description of linguistic facts on every linguistic level: morphological, syntactic, semantic, and even the level of pragmatics and discourse. In addition to the linguistically-motivated conception of NLP, we emphasize the origin of such research field, the place occupied by NLP inside a multidisciplinary scenario, their objectives and challenges. Finally, we provide some remarks on the automatic processing of Brazilian Portuguese language.

CAPACIDADE DE ABSORCAO DE AGUA, OLEO E FORMACAO DE ESPUMA DA FARINHA E CONCENTRADO PROTEICO DE FEIJAO-GUANDU (CAJANUS FLAVUS DC.)

Pigeonpea protein concentrate was prepared from full-fat decorticated raw flour. The water holding capacity of pigeonpea flour of decorticated seeds is 75% and its oil absorption capacity a 30%. The water holding capacity of the protein concentrate is three times the dry weight. The oil absorption capacity of the concentrate was 1,29 mL oil/g protein. The whipping capacity of the pigeonpea flour and its protein concentrate were evaluated.

OLEO ESSENCIAL EM ALGUMAS ESPECIES DE EUCALYPTUS

In this work we used leaves of four species of Eucalyptus - E. bicostata Maiden, E. deanei Maiden, E. dunnii Maiden and E. viminalis Labill, grown in Colombo, Parana State, Brazil. Preliminary studies were done, in the following sequence: botanic identification, olfactory research, extraction and purification of the essential oil of each species. The physical and chemical tests done were the following: relative density, refractive index, optical rotation, solubility, coagulation point and cineol percentage. The essential oils analysed through gaseous chromatography, presented the following cineol percentage: E. bicostata Maiden - 26.92%, E. deanei Maiden - 70.21%, E. dunnii Maiden - 53.16% and E. viminalis Labill - 23.05%.

Sazonalidade, tarifa mais conveniente e fator de carga em indústria de processamento de cana

This paper represents the results of the work carried out in order to study the condition of seasonal consumer, the load factor and the more convenient tariff for a sugar mill located in the Vale do Paranapanema, SP, Brazil. Therefore, data of consume and registered demand were collected during the quadriennium 1990 to 1994. The studies showed that the factory did not maintain the condition of seasonal consumer of electric energy during the analysed period. Low values of the load factor observed in the period showed a non rational use of electric energy supplied by the concessionary. The results showed that only in one situation (load retired in top equal to 90%) the most convenient tariff is the horo-sazonal azul. In the other situations the most convenient tariff is the conventional one.
