The aim of this study was to verify the carrot cooking most suitable method to minimize nutrient losses. Carrot peel slices were subjected to pre cooking tests that were initiated with 0.5 min of duration and then increased in 0.5 min successively. The carrot pieces texture was monitored during the pre tests so all would havethe same texture independent of the type of cooking. The degree of softennes was evaluated by pressuring the pieces between the toes. The carrot pulp and pell were subjected to four types of heat treatment (pressure, immersion, microwave, and steam), after that they were pounded with a food processor and stored at -18 ºC. The nutritional analyses were as follow: The evalu determination of proteins, lipids, fibers, sugars reducers, total of ascorbic acid content and minerals (iron, calcium, zinc, magnesium, potassium, phosphorus, and calcium). The analyses were accomplished with fresh carrot and after cooking with the different methods. The peel of the carrot presented as amounts of proteins, lipids, fibers percentages, sugars reducers, total and ascorbic acid content equivalent to the pulp. In addition, the minerals content was superior in the peel in relation to the pulp, presenting respective percentages of 38,10%, 95,12%, 47,04%, 58,88%, 70,27% and 21,27%. There were nutrient losses in relation to the raw vegetable, when the carrot pieces were submitted to the different cooking methods. The methods of steaming and microwave had lower nutritional losses.

Ceriporiopsis subvermispora is a selective fungus in the wood delignification and the most promising in biopulping. Through the lipid peroxidation initiated by manganese peroxidase (MnP), free radicals can be generated, which can act in the degradation of lignin nonphenolic structures. This work evaluated the prooxidant activity (based in lipid peroxidation) of enzymatic extracts from wood biodegradation by this fungus in cultures containing exogenous calcium, oxalic acid or soybean oil. It was observed that MnP significant activity is required to promote lipid peroxidation and wood delignification. Positive correlation between prooxidant activity x MnP was observed up to 300 IU kg-1 of wood.

O intuito do presente artigo é analisar os resultados de uma pesquisa conduzida junto a alunos de dois cursos de alemão como língua estrangeira. A investigação se insere no marco teórico dos estudos sobre crenças. Pretende-se pôr em relevo a percepção do alunado a respeito do conteúdo programático das aulas que frequenta - e, sobretudo, os valores e pesos que deposita sobre cada elemento que integra uma aula de língua estrangeira: de um lado, que importância dedica às atividades de desenvolvimento das "quatro habilidades" (ler, escrever, falar e ouvir), ao trabalho com a gramática, com o léxico e com aspectos inter e transculturais.
