Avaliação das Farinhas de Peixe e Pena, no Confinamento de Bezerros Leiteiros Desmamados, Através de Dietas Calculadas em Termos de Proteína Bruta ou de Proteína Metabolizável

The objectives of this work were to evaluate three protein sources - soybean meal, fish meal and feather meal - and two methods of calculation of rations - the calculated in terms of crude protein (CP), according to recommendations of NRC (1988); and the proposed by the AFRC (1993), and calculated in terms of metabolizable protein (MP) - through the performance of calves. The animals were confined and submitted to five diets, that varied only protein sources in its composition, thus discriminated: SM- Soybean Meal, FsM- Fish Meal, FeM- Feather Meal, FsMU- Fish Meal and Urea, and FeMU Feather Meal and Urea. A complete diet was supplied, composed of 40% of sorghum silage and 60% of concentrate. All treatments possessed about of 2.56 Mcal/kg DM of metabolizable energy, being the treatments SM, FsM and FeM calculated by the system of CP, with 18% of CP, and the treatments FsMU and FeMU, calculated by the system of MP, with 16.3% of CP and a same amount of metabolizable protein than the treatment SM, with 112.0 grams of MP/day. Individually, the treatments did not present significant differences (P > 0.05) in the final alive weight, in daily gain weight and in dry matter intake, having differences only in the feed:gain ratio. The best feed:gain ratio happened in the treatment FsM and the worst in the treatment FeMU. It is concluded that the MP method provides similar results to the method of CP. The treatments with fish meal provide larger weight gains, smaller intake and better feed:gain ratio than the treatments with feather meal, staying the treatment soybean meal with intermediary daily gain.

Complexos fosfínicos e suas aplicações na medicina

Phosphines are well known to chemists. The ligands themselves are widely used in organic synthesis (e.g. The Wittig reaction) and transition metal phosphine complexes have been studied extensively primarily for their applications as hydrogenation catalysts (e.g. Wilkinson's catalyst). In this article attention is focused on the biological properties of phosphines and metal phosphine complexes since the triethylphosphine Au(I) complex, auranofin, has been used as antiarthritic drug for clinical use. This fact has provided a stimulus for exploration of the biological chemistry of phosphines and their metal complexes. Metal phosphine complexes also offer potential as heart-imaging agents and anticancer drugs.

O comportamento fotoquímico dos complexos pentaaminas de rutênio(II) com ligantes pi insaturados

A general overview on the photochemical behaviour of [Ru(NH3)(5)L](2+) complexes (where L is a pi ligand) is presented. The proposed mechanisms and techniques employed for the study of these reactions are discussed. Emphasis is made on the mechanisms that allow the identification of the reactive excited state of the [Ru(NH3)(5)py](2+) complex.

Os complexos granitoides Cunhaporanga e Tres Corregos (PR) zoneamento magmatico e implicacoes geotectonicas

Geological, petrographic, chemical and zircon typology data from the Cunhaporanga and Tres Corregos granitoid complexes are presented and discussed. Both complexes of Late Precambrian age evolved by crystal fractionation. By its zircon typology the Cunhaporanga is classified as a low temperature calc-alkaline batholith and the Tres Corregos as a medium temperature calc-alkaline complex. This classification implies a major participation of mantle material during the generation of the Tres Corregos magma in relation to the Cunhaporanga ones. In this way both complexes define a magmatic zoning from NW to SE done by a increasing in the depth of magma generation. -from English summary

Borohidreto complexos de cobre (I) contendo difosfinas. Caracterização espectroscópica e comportamento térmico

Tetrahydroborate complexes of copper (I) with bidentate phosphines, [Cu(η 2-BH 4)(dppm)] (1), [Cu(η 2-BH 4)(dppe)] (2), [Cu(η 2-BH 4)(cis-dppet)] (3) and [Cu(η 2-BH 4)(dppb)] (4) (dppm = bis(diphenylphosphino)methane; dppe = 1,2-bis(diphenylphosphino) ethane; cis-dppet = 1,2-cis(diphenylphosphino)ethene; dppb = 1,4-bis(diphenylphosphino)butane) were prepared and characterized by elemental analysis, infrared spectroscopy, NMR and thermogravimetric analysis. The IR data for 1-4 showed bands typical of a bidentate coordination of BH 4 group to the copper atom and the 31P{ 1H} NMR spectra indicated that the phosphorous atoms are chelating the metal centre. The thermal behavior of the compounds was investigated and suggested that their thermal stability is influenced by the phosphines. Their thermal stability decreased as follows: [Cu(η 2-BH 4)(dppe)] (2) > [Cu(η 2-BH 4)(dppm)] (1) > [Cu(η 2-BH 4)(dppb)] (4) > [Cu(η 2-BH 4)(cis-dppet)] (3). According to thermal analysis and X-ray diffraction patterns all compounds decomposed giving Cu(BO 2) 2, CuO, CuO 2 and Cu as final products.
