13. Minerais orgânicos na prevenção hiperparatireoidismo nutricional secundário em equinos / Prevention of secondary nutritional hyperparathyroidism in horses using organic minerals
Não é raro criar equinos em áreas onde baixo teor de fósforo, indisponibilidade de cálcio e teor de oxalato nas plantas podem levar a desequilíbrios resultando em hiperparatireoidismo nutricional secundário. Normalmente, os minerais atuam no organismo na forma orgânica e não inorgânica, porém, ainda há controvérsia na literatura quanto ao uso de

14. Cromatografia de afinidade por íons metálicos imobilizados (IMAC) de biomoléculas: aspectos fundamentais e aplicações tecnológicas
Immobilized Metal Ion Affinity Cromatography - IMAC - is a group-specific based adsorption applied to the purification and structure-function studies of proteins and nucleic acids. The adsorption is based on coordination between a metal ion chelated on the surface of a solid matrix and electron donor groups at the surface of the biomolecule. IMAC is a highly

15. Chelated minerals for poultry
Organic minerals have been subject of an increasing number of investigations recently. These compounds can be considered the most significant event regarding commercial forms of minerals targeting animal supplementation in the last decades. Minerals, especially metals, are usually supplemented in poultry feeds using cheap saline sources and have never requir

16. Computational histomorphometry of broiler chickens organs submitted to two distinct feeds: chelated minerals and not chelated minerals diet. / Morfometria computacional de órgãos de frangos de corte submetidos a duas dietas distintas: suplementação mineral quelada versus suplementação mineral tradicional
This research studied the influence of chelated minerals in broilers chickens nutrition as well as the constitution and morphology of bone, liver and intestine of these animals, by means of the utilization of mathematical and computational techniques including computer vision, pattern recognition and statistical analysis. Additionally, the immunological resp

20. Radiossensibilidade gama de Cladonia substellata Vainio (lÃquen) e o conseqÃente efeito sobre rochas calcÃrias / Gamma radiosensibility of Cladonia substellata vainio (lichen) and the consequent chelating effect on calcareous rocks
Soil is an unconsolidated surface that recovers the rocks and maintains animal and plant life on Earth. It is formed from climatic and biotic relationship, modified by topography that acts on original material, over a long period of time. Concerning biotic activities, one may emphasize that performed by lichens, which allow the succession of rocky substratum

22. Chemical absorption of H2S for biogas purification
This work presents an experimental study of purification of a biogas by removal of its hydrogen sulphide (H2S) content. The H2S was removed by means of chemical absorption in an iron-chelated solution catalyzed by Fe/EDTA, which converts H2S into elemental sulphur (S). Preparation of the catalyst solution and the results of biogas component absorption in the

23. Efeito da suplementação dietética com micro minerais orgânicos na produção e qualidade de ovos de galinhas poedeiras / Effects of diet supplementation with organic trace minerals on production and egg quality for laying hens
A experiment was conducted to study the effect of organic trace mineral sources supplementation on egg production and quality for laying hens. It were used 8 treatments: one treatment with every trace minerals on inorganic form, one treatment with all minerals on organic form and 6 treatments where only one mineral were organic. The trace minerals were: zinc

24. Oxidação de hidrocarbonetos com peroxido de hidrogenio catalisada por renio em fase homogenea e heterogenea
Nowadays, there has been an increasing number of studies on the oxidation of organic compounds such as olefins, phenols, anisols, alcohols and alkanes catalyzed by rhenium complexes. In the first part of this work, the oxidation of hydrocarbons with anhydrous hydrogen peroxide, catalyzed by CH3ReO3, using acetonitrile as a solvent at 80°C was studied. In th
