Processo de Preparação de Zirconia Dopada e não Dopada pela Rota Sol-Gel Usando Nitrato de Zirconila como Material de Partida compreendendo as etapas de preparação de uma solução de nitratos de zirconila e outros nitratos metálicos em solução aquosa com composto orgânico de etanol metanol ou acetona, através do controle de molaridade. Embora não limitantes, valores ideais para molaridade das soluções são: entre 1,00 e 0,29 para obtenção de pó entre 0,29 e 0,18 para obtenção de superfície recoberta e entre 0,18 e 0,13 para obtenção de filmes finos. Manter a solução a 0°C para formação de filmes finos por imersão do substrato ou monocristal com velocidade constante ("dip-coating") ou por rotação a velocidade constante ("spinning"), ou para recobrimento de superfícies metálicas através de imersões sucessivas do substrato metálico a velocidade constante ("dip-coating"). Elevar a solução a 50°C para hidrolização e formação de um gel em forma de pó, secagem de pó ou liofilização, calcinação e moagem dos aglomerados.

The purpose of this study was to evaluate the commercial cuts, loin tissues and composition proportions in meant from five racial groups: Alpine, ½ Boer + ½ Alpine (½ BA), ½ Anglo Nubian + ½ Alpine (½ ANA), ¾ Boer + ¼ Alpine (¾ BA), ¼ Boer + ¼ Alpine + ½ Anglo Nubian (Tricross), submitted to three slaughter weights (25, 30 and 35kg) in feedlot, using a complete diet. The crossing of Boer and Anglo Nubian with Alpine females only improved, in kids, the yield of cuts considered third category such as neck and rib. Slaughter body weights between 30 and 35kg should be preferred due to increase in the proportion of the loin, reduction in the proportion of the neck in Alpine and increase in the leg in Alpine and ¾ Boer, beyond the appropriate amounts of intermuscular fat and muscle.

Transparent monoliths and films of urea cross-linked tripodal siloxane-based hybrids (named tri-ureasils) were prepared by the sol-gel process, under controlled atmosphere (inside a glove box) and ambient conditions and their structure and optical features were compared. X-ray diffraction data point out that all the materials are essentially amorphous and Si-29 NMR reveal an increase in the condensation degree (0.97) for the hybrids prepared under controlled atmosphere relatively to that found for those prepared under ambient conditions (0.84-0.91). The tri-ureasils are white light emitters under UV/Visible excitation (from 250 to 453 nm) being observed for the composites prepared inside the glove box a significant enhancement (60-80 %) of the absorption coefficient and higher emission quantum yield values (similar to 0.27 and similar to 0.20 for monoliths and films, respectively) relatively to those synthesized under ambient condition.

This study was carried out to evaluate the morphometric characteristics, the yield and the centesimal composition of different cuts of the Barbado's (Pinirampus pirinampu) flesh, captured in the Itaipu Reservoir. Were used 55 animals randomly distributed into three classes of body weight [less than 620 g (n = 15), between 620 and 1.120 g (n = 16) and greater than de 1.120 g (n = 24)]. Were measured the standard length (SL), the total length (TL), the head length (HL), the head height (HH), the trunk length (TRL), the trunk height (TH) and width of the trunk (WT). Then were established the morphometric relationships: (HL/SL), (HL/HH), (SL/TL), (WT/TRL), (WT/TH) (TH/TRL). Afterwards were measured the flesh's cut yield and the residue waste yield called: trunk (TC), fillet (FILLET), abdominal fillet (AF), head (HEAD), viscera (VISC), fin, spine and skin (SKSF). The levels of moisture, ash, fat and crude protein from FILLET and AF were determined. The body weight affected (P<0.05) the WT/TRL, WT/TH, TH/TRL, TR, FILLET, HEAD and SKSF, however didn't affected the centesimal parameters. In conclusion, the Barbado (Pinirampus pirinampu) has allometric growth and the flesh processing from fishes with more than 620 g provides better yields of edible parts. In addition, the chemical composition of meat suggests its potential for use in the manufacture of artisanal or industrial products.
