1. Effect of Semi-Apical Angle on the Crush Mechanics of Metallic Bi-Tubular Tubes under Dynamic Axial Loading
ABSTRACT Aerospace and automotive industrial advancement demands high energy absorbing structures for the human and equipement safety during transportaion and accidental emergencies. Thin-walled metallic tubes applications in the structures serve the purpose by absorbing energy during such dynamic scenarios. A new concept is presented in this study, involvin

2. Predicting post-absorptive protein and amino acid metabolism
ABSTRACT Sustainable production of adequate quantities of food to support a growing human population is a worldwide goal. Under current feeding conditions in the United States, dairy cattle convert dietary nitrogen to milk nitrogen with 25% efficiency. The remaining 75% is excreted, which contributes to air and water quality problems and reduces economic per

3. Evaluation of cation-anion diets in calcium metabolism in ruminants
The objective of this study was to evaluate the use of the dietary cation-anion balance (DCAB) on the calcium metabolism in male Nellore steers with a mean age of 10 months. Three experimental diets were tested: a cationic diet, a diet consisting of Tifton hay only, and an anionic diet with +15.2, +23.9 and −10.0 mEq/100 g DM of DCAB values in the diet. Th

4. Avaliação de métodos para análise de nitrogênio amoniacal em fluido ruminal e de óxido crômico em amostras de fezes de bovinos / Evaluation of methods for analyses of ammonia nitrogen in rumen fluid and chromium in cattle feces
This dissertation was based on two different experiments. The first one was conducted to evaluate the accuracy of two different methods in measuring the ammonia nitrogen (N-NH3) concentration in rumen fluid: a catalyzed indophenol colorimetric reaction (CICR) and the Kjeldahl distillation (KD). Five buffered standard solutions containing volatile fatty acids

5. Estrutura eletrÃnica e propriedades espectroscÃpicas de compÃsitos polianilina/ouro: uma investigaÃÃo ab initio
In this dissertation we use ab initio quantum chemistry theoretical methods to examine possible effects that the presence of a small number of attached gold atoms could have upon the spectra of polyaniline (PANI) oligomers. We have investigated in special the theoretical fluorescence spectra of the gold-polyaniline composites, by using the Hartree-Fock appro

6. Phosphorus utilization by sheep: effects of different levels on true absorption and fecal losses / Utilização de fósforo por ovinos: efeitos de diferentes concentrações na absorção real e perdas fecais
O objetivo do presente trabalho foi determinar a absorção real de fósforo (P), as perdas totais fecais e endógenas do mineral em ovinos alimentados com diferentes concentrações de P na dieta, através da determinação do P inorgânico e radioativo em amostras de sangue, fezes, urina, saliva e líquido do rúmen. Vinte e quatro ovinos machos, castrados

7. Aproveitamento de Lodo de Estação de Tratamento de Água em Cerâmica Vermelha
The water treatment stations (WTA) have been researching solutions for the recycling of the residue generated in the water treatment process this residue is called WTA mud. Presently, the adopted solutions are the releasing of the residue into sanitary landfills or into the sewer system. The red ceramics presents an enormous potential to contribute for the s

8. On the origin of the satellite peaks in alpha particle spectra
In this work we describe the results obtained with S3590-06 and ion-implanted diodes for alpha particle spectrometry. Satellite peaks were also investigated in order to identify not only the origin of these phenomena, but also the importance of the guard ring region on their relative intensities. The preliminary results indicate that the true cause of the sp

9. STUDY OF THE STRUCTURAL AND MAGNETIC PROPERTIES OF Zn1-xMnxIn2Se4 SYSTEM / ESTUDO DAS PROPRIEDADES ESTRUTURAIS E MAGNÉTICAS DO SISTEMA Zn1-xMnxIn2Se4
This work reports a systematic study on the crystal growth and magnetic and structural properties of the diluted magnetic semiconductors (SMD) Zn1-xMnxIn2Se4. Crystals with Mn concentrations $0leqslant xleqslant 1.00$ were grown by chemical vapour transport (CVT). Through x-ray powder diffraction patterns and Laue diagrams of single crystal we studied the tr

10. Modelagem quântica de inibidores enzimáticos. / Quantum modelling of enzimatic inhibitors.
We have made a structural and electronic characterization of the enzyme inhibitors E-64 and CA030 using quantum chemistry techniques. Geometry optimizations are performed in the ab initio level with the Hartree-Fock and Density Functional Theory methods and these structures are then compared with crystallographic results obtained from the Protein Data Bank.

11. Obtenção de frações proteicas de sangue bovino : composição, valor nutritivo e propriedades funcionais
The objective of this thesis was to obtain bovine blood proteins and to study their functional and nutritional properties to be used in human foods. Blood of healthy bovines was collected from a slaughterhouse using sodium citrate to prevent coagulation and subsequently it was fractionated in a centrifuge separator into plasma and blood cell concentrate. The

12. Estudo metabólico-nutricional em alcoólatras crônicos submetidos a dietas enterais quimicamente definidas / Metabolic and nutritional effects of enteral diets on chronic alcoholic patients
The objective of this research was to determine the utilization of nitrogen from chemically defined enteral diets ( ED), compared with oral diets, by groups of chronic alcoholic patients. The effect of ED on the recovery of nutritional status by the patients was also determined. The methods used were metabolic nitrogen balance ( WE ) and amino acid analysis
