As plantas medicinais podem ser usadas como fontes alternativas de nutrientes minerais na dieta alimentar. Elementos como ferro, manganês e zinco apresentam biodisponibilidade variável em função de suas formas químicas (espécies) presentes em um alimento. Este trabalho tem como objetivo avaliar o teor e a biodisponibilidade de ferro, manganês e zinco em extratos da casca do fruto e das folhas de Caesalpinia ferrea Martius por Espectrometria de Absorção Atômica com Chama (FAAS). Os agentes extratores testados foram as soluções de NaOH 0,05 mol. L-1, tampão Tris-HCl 0,05 mol.L-1 (pH= 8), tampão Tris-HCl 0,05 mol.L-1 (pH = 8) em dodecil sulfato de sódio (SDS) 1% (m/v), HCl 0,05 mol.L-1 e água quente (60 ºC). A casca do fruto e as folhas de Caesalpinia ferrea Martius apresentaram níveis altos de ferro e manganês quando comparados aos de outras plantas medicinais. Os elementos estudados mostraram predominante associação com compostos de alta e baixa massa molecular, espécies solúveis e insolúveis em água. Dentre os elementos analisados, o ferro apresentou melhor biodisponibilidade na casca do fruto e nas folhas. Manganês e zinco se mostraram mais biodisponível nas folhas. A casca do fruto e as folhas de Caesalpinia ferrea Martius podem ser uma fonte alternativa de ferro, manganês e zinco na dieta alimentar.

We evaluated the effect of additives the basis of propolis and monensin on ingestive behavior (grazing -GRA, rumination lying -RLY, rumination in foot -RFO, rumination -RUM; idleness lying -ILY, idleness in standing -IDS, idleness -IDL, walking -WAL, posture standing -POS, posture lying -PLY, intake of supplement and water -ISW) of heifers in Tifton 85 grazing. The treatments were: no additive (NAD); propolis - PRO (33.24 mg animal-1 of total flavonoid in apigenin), and monensin -MON (100 mg animal(-1)). Were used five heifers treatment(-1) for evaluation of ingestive behavior during 12 hours of total valuation, which was divided into three periods. Used a factorial design into 3 x 3 for evaluation of ingestive behavior as a function of the evaluation periods. Were utilized three paddocks of 2.9 acres of grass Tifton 85. The additives and mineral supplement (50 g animal(-1)) were provided with 200 g of corn meal to 17 hours. For all activities of the ingestive behaviors observed the effect of period on the time spent on of different activities. The activities of GRA and ISW were higher in the third period (15hours to 19hours) compared to the first period (7hours at 11hours). For IDL and PLY, there was a higher time in minutes for heifers treatment with PRO in the period of 7hours at 11hours, compared to other treatments (NAD and MON). Thus, it is concluded that the use of the additive based on propolis enables sodium monensin replacement, to heifers maintained on pasture without changing eating behavior as well as providing greater idleness during the day the without affecting animal performance.

The literary criticism was developed in Brazil in the period that comprehends the end of the 19th century and the beginning of the 20th century. During that time, the mean of dissemination of the criticism were the footnotes of the newspapers, places in which literature was discussed and the critics expressed their personal impressions about literary works with the objective of orientating the good taste of the readers. With the progressive evolution of journalism and of the newspaper's audience, the criticism columns became incompatible with the informative part of the periodicals, being transferred to the literary supplements, during a transition phase, until it was concentrated in the universitary field. This change in the paradigms of the production of criticism also caused a change in the profile of the literary critics and in the criteria to do the criticism. Before, if the critics were professionals that only needed to have enough erudition to judge the literary works, they turn into literature experts and need to use scientific methodologies in the literary analysis, while the cultural journalist begins to look at the events and literary works as products which belong to a market that needs to be reported. This research proposes studying and comparing the critics published in the column Prosa de Sábado, of the literary supplement Sabático, produced by Silviano Santiago, critic of an academic origin, and Sérgio Augusto, journalist critic, with the objective of identifying similarities and contrasts between them, and analyse the relation of this critics with their distinct fields of literary legitimation, as well as reflecting about the presence of the literary criticism and of the critics in the current press
