Advanced oxidation of organic matter in natural waters with TiO2 immobilized films

The purpose of this paper is to report the development of a laboratory -scale pilot based on the use of TiO2 photocatalytic thin films for degrading organic matter and pollutants from natural water. The photoreactor consists of a channel inclined with a glass plate coated by TiO2 in both faces and fixed at 1 cm from the bottom. The thin film was immobilized on the glass plates by Sputtering technique. The reactor was designed to be able of reproduce the hydraulic conditions of a water treatment plant. In experimental testing of degradation of organic matter with solar irradiation maximum efficiency of 50% was achieved. At optimal conditions it was possible to exceed the efficiencies of a full scale preozonization in a water treatment plant , thus providing a more sustainable process

Medidas morfométricas da carcaça de cordeiros de diferentes genótipos submetidos a dois sistemas de produção.

Resumo: Objetivou-se avaliar a influência do sistema de produção, bem como de diferentes grupos genéticos sobre as características morfométricas da carcaça de cordeiros. Foram observados 24 animais, machos não castrados, das raças ½Dorper x ½SPRD, ½Santa Inês x ½SPRD e ½Somalis x ½SPRD, submetidos à terminação a pasto e em confinamento. Os animais foram abatidos com peso vivo médio de 30 kg. As carcaças foram pesadas e refrigeradas a 4ºC por 24h, quando então foram mensuradas as seguintes medidas morfométricas: comprimento corporal, perímetro torácico, perímetro da perna, comprimento da perna e comprimento interno. O sistema de produção interferiu nas medidas de perímetro da perna e comprimento interno, não havendo diferença significativa (P>0,05) para as demais medidas. Os genótipos estudados não influenciaram na medida de perímetro. As medidas de comprimento da carcaça, perímetro da perna e comprimento interno não diferiram estatisticamente para os mestiços ½Dorper x ½SPRD e ½Santa Inês x ½SPRD, no entanto esses genótipos apresentaram diferença significativa para a raça ½Somalis x ½SPRD nesses parâmetros. O sistema de produção não acarretou mudanças importantes para as medidas morfométricas de comprimento de carcaça, perímetro torácico e comprimento da perna. O mestiço ½Dorper x ½SPRD apresentou as melhores médias para as medidas estudadas. [Morphometric carcass characteristics of lambs of different genotypes under two production systems]. Abstract: Objectified to evaluate the influence of production system, well as of different genetic groups on the morphometric characteristics of the carcass of lambs. 24 animals had been observed, males not castrated, of breeds ½ Dorper x ½ SPRD, ½ Santa Inês x ½ SPRD and ½ Somalis x ½ SPRD, submitted to termination grass and confinement. The animals had been abated with average alive weight 30 kg. The carcasses had been weighed and cooled 4ºC for 24h, when then following morphometric measures had been measured: corporal length, thoracic perimeter, perimeter of leg, length of leg and internal length. The production system intervened with the measures of perimeter of leg and internal length, not having significant difference (P>0.05) for excessively measures. Studied genotypes had not influenced in measure of perimeter. Measures of length of carcass, perimeter of leg and internal length hanot statistical differed for the mestizos ½ Dorper x ½ SPRD and ½ Santa Inês x ½ SPRD, however these genotypes had presented significant difference for the breed ½ Somalis x ½ SPRD in these parameters. The production system does not cause important changes for morphometric measures of carcass length, thoracic perimeter and length of the leg. The mestizo ½ Dorper x ½ SPRD presented best averages for studied measures

Características qualitativas da carcaça de cordeiros de diferentes genótipos submetidos a dois sistemas de produção.

Resumo: No sistema de produção de carne, as características qualitativas da carcaça são de fundamental importância para complementar a avaliação do desempenho animal. Assim, objetivou-se avaliar a influência do sistema de produção, bem como diferentes genótipos sobre as características qualitativas da carcaça de cordeiros. Foram observados 24 animais, machos inteiros, das raças ½Dorper x ½SPRD, ½Santa Inês x ½SPRD e ½Somalis x ½SPRD, submetidos à terminação a pasto e em confinamento. Os animais foram abatidos com peso vivo médio de 30 kg. As carcaças foram pesadas e refrigeradas por 24h, quando foram extraídos os Longissimus dorsi e neles mensurados grau de marmoreio, distribuição e textura da gordura, além da cor e textura da carne. A distribuição da gordura na carcaça não sofreu influência de nenhum tratamento (P>0,05), enquanto que o grau de marmoreio e textura da gordura teve interferência do sistema de produção, assim como a cor da carne. Os genótipos avaliados não diferiram nos atributos de distribuição da gordura, como também na textura e cor da carne. Os cordeiros ½Santa Inês x ½SPRD apresentaram as menores médias para grau de marmoreio e textura da gordura. O mestiço ½Dorper x ½SPRD proporcionou os melhores resultados para os parâmetros qualitativos avaliados nesta pesquisa. [Qualitative characteristics the Carcass Lambs Different Submitted Genotypes Two Systems of Production]. Abstract: In system meat production, qualitative characteristics of carcass are basic importance to complement the evaluation of animal performance. Thus, objectified to evaluate the influence of production system, as well different genotypes on qualitative characteristics carcass of lambs. Twenty four animals had been observed, entire males, breeds ½ Dorper x ½ SPRD, ½ Saint Ines x ½ SPRD and ½ Somalis x ½ SPRD, submitted the termination the grass and in confinement. The animals had been abated with average alive weight of 30 kg. The carcasses had been weighed and cooled for 24h, when they had been extracted Longissimus dorsi and in them measured degree of marbling, distribution and texture of the fat and texture beyond the color and texture of the meat. Distribution of fat in carcass did not suffer influence from no treatment (P>0.05), whereas the degree of marbling and texture of fat had interference of the production system, as well the color of meat. Evaluated genotypes had not differed in distribution attributes of fat, as well as in texture and color of meat. The lambs ½ Saint Ines x ½ SPRD presented the average minors for the marbling attributes and texture of fat. The mixed race ½ Dorper x ½ SPRD provided the best ones resulted for the attributes evaluated in this research

Enological potential of 'Pinot Noir' grape and wine from a tropical climate, in the Chapada Diamantina - BA, Brazil.

Tropical viticulture, although relatively new, has achieved significant technological developments in Brazil, making possible cultivation of vines in areas beyond standard traditional winegrowing areas worldwide. Techniques such as irrigation, the use of growth hormones in vines and production control at different times during the year, are being applied in other regions of Northeast Brazil for the production of wines. Some varieties express the best of their viticultural and enological potential in a given ecosystem, and Pinot Noir variety is very difficult to produce because presents a high susceptibility to fungal diseases (Reynier, 2007)

Enological characteristics of ?Chardonnay? grapes produced in tropical climate in the Northeastern of Brazil.

The climate has very strong influence on the vine performance, being the main factor to determine the potentiality of wine from a new region. There is also interactions among wine quality and other factors, such as soil, variety and the management adopted in the vineyard. In tropical climates, as in the São Francisco Valley (VSF), located at 350 m of elevation and 9º S of latitude, vines grown continuously, and with the use of specific technologies, it is possible to have two harvests per year in the same vineyar

Medidas morfométricas de carcaça de cordeiros terminados sob dois sistemas de produção.

Resumo: Utilizou-se 39 cordeiros, sendo 13 cordeiros de cada genótipo, meio sangue Dorper, Santa Inês e Somalis, todos machos inteiros. Com dois sistemas de terminação em pastagem nativa e cultivada, foram encaminhados ao abate com peso mínimo de 25kg e escore corporal igual ou maior que três. O peso vivo (PV) exerce inferência sobre o peso de carcaça quente (PCQ) (r = 0,96), comprimento do corporal (CC) (r = 0,75), perímetro torácico (PT) (r = 0,91) e o comprimento interno da carcaça (CIC) (r = 0,71), indicando elevada correlação entre esses índices. O escore corporal (ECC) está fracamente correlacionado com peso de carcaça quente (PCQ) (r = 0,47) e fria (PCF) (r = 0,48), perímetro torácico (PT) (r = 0,47) e área de olho de lombo (AOL) (r = 0,41), indicando a possibilidade de usar esse parâmetro para escolher o momento de encaminhar os animais para ao abate. A área de olho de lombo correlaciona-se positivamente com todas as variáveis analisadas, predizendo uma carcaça com qualidade para o abate. Todas as outras variáveis estão correlacionadas, sendo importante na escolha do momento do abate. Morphometrics measures of carcass of lambs finished under two systems of production. Abstract: Used 39 lambs, being 13 lambs of each genotype, blood way Dorper, Santa Inês and Somalis, all entire males. With two systems termination in native and cultivated pasture, they had been directed it abates with minimum weight of 25kg and props up corporal equal or bigger that three. The alive weight (PV) exerts inference on the weight of hot carcass (PCQ) (r = 0,96), length of corporal one (CC) (r = 0,75), thoracic perimeter (PT) (r = 0.91) and the internal length of the carcass (CIC) (r = 0.71), indicating raised correlation between these indices. It props up corporal (ECC) weakly is correlated with weight of hot carcass (PCQ) (r = 0,47) and cold (PCF) (r = 0,48), thoracic perimeter (PT) (r = 0,47) and area of eye of loin (AOL) (r = 0.41), indicating possibility use this parameter to choose moment to direct the animals for it abates. The area of eye of loin positively correlates with all the analyzed variable, predicting a carcass with quality abates for it. All other variable are correlated, being important in choice of moment abate
