Equilibrium Data For Systems Composed By Cottonseed Oil + Commercial Linoleic Acid + Ethanol + Water + Tocopherols At 298.2 K
The present paper reports liquid-liquid equilibrium data for the system refined cottonseed oil + commercial linoleic acid + ethanol + water at 298.2 K. The experimental data were used for adjusting parameters of the NRTL and UNIQUAC models. The global deviations between calculated and experimental concentrations were 0.80% for the NRTL model and 1.44% for the UNIQUAC equation. The influence of the solvent on the distribution coefficient of tocopherols was also studied. UNIQUAC and NRTL interaction parameters between tocopherols and the other pseudocomponents were determined assuming that the nutraceutical compound is present at infinite dilution in the liquid-liquid equilibrium system. The obtained parameter set enables the simulation of liquid-liquid extractors. © 2005 Elsevier B.V.

Equilibrium Data For The System Rice Bran Oil + Fatty Acids + Ethanol + Water At 298.2 K
This work presents experimental data for the model system refined rice bran oil + commercial oleic acid + ethanol + water at 298.2 K. These data were correlated by the NRTL and UNIQUAC models, with a global deviation of approximately 0.7% for both models. The equilibrium of crude rice bran oil + aqueous ethanol was predicted with success using the adjusted interaction parameters, with deviation between calculated and experimental results not higher than 0.54%. The results showed that the addition of water to the solvent increases the solvent selectivity, reducing the losses of neutral oil and nutraceutical compounds, and expands the region of phase splitting, allowing the refining of highly acidic crude rice bran oils by solvent extraction.482367373Rukmini, C., Chemical, nutritional and toxicological studies of rice bran oil (1988) Food Chem., 30, pp. 257-268Deckere, E.A.M., Korver, O., Minor constituents of rice bran oil as functional foods (1996) Nutr.

Finance and policy in the realization of the church values seized in 1922
Financial and politics aspects of the realization of the church values seized in 1922 under the pretext of rendering assistance to the starving people are analyzed in the article. Author examines relationship between People’s Commissariat for Finance and three organizations of the all-Russian C.E.C. in which possession were the seized values. The conducted study gives grounds to assert that no sales of the church values abroad for purchase of bread for starving people were carried out and the fight against famine and it’s consequences was waged with the funds of the state Treasury. The seizure of the values from the churches in 1922 lasted too long time. The concentration of the values in Moscow took several years. Having “realized” values authorities initially announced preliminary and demonstrative purchase of the food at a very small amount — 1 million of gold rubles. Then the sale of the church values for soviet depreciated rubles made by the Central Committee for Famine Relief of the all-Russian С.E.C. to Narcomfi n according to agreement of 29 July 1922 was likewise presented by the soviet leaders. The article describes the history of the fruitless efforts undertaken by the members of Pomgol CC to obtain the gold credits, and points out more correct official cost of the seized values. As an important conclusion the author asserts that the policy of double standards pursued by the Narkomfin in the assessment of the seized church property let the financial department under the pretext of ‘’famine relief’’ get a signifi cant profi t
Estratégias de micropropagação de calibrachoa sellowiana (sendtn.) wijsman e rosmarinus officinalis l
TCC (graduação)- Universidade Federal de Santa Catarina. Campus Curitibanos. Agronomia.A micropropagação de plantas é uma estratégia, que se vem ao encontro das necessidades dessas duas espécies aqui apresentadas o Rosmarinus officinalis e Calibrachoa sellowiana ambas com potencial econômico a ser explorado. O Alecrim (R. officinalis) planta de origem do Mediterrâneo, possui características medicinais, podendo ser amplamente utilizado na indústria de cosméticos e medicamentos. A Petúnia (C. sellowiana) com seus atributos ornamentais, com valor de conservação e pioneira na recuperação de áreas degradadas e, por se tratar de uma espécie nativa dos campos sulinos, do Bioma Mata Atlântica tem um alto valor ecológico. Além disto, esta duas espécies possuem características para ser adotada como fonte de renda alternativa para agricultores. No presente trabalho segmentos nodais e apicais foram extraídos de plantas matrizes de Rosmarinus officinalis e de Calibrachoa sellowiana, foram utilizados em diferentes protocolos para a micropropagação através do cultivo em meio de cultura com diferentes tipos e concentrações de fitorreguladores, durante a indução, regeneração e alongamento de brotos. Para a introdução in vitro de Rosmarinus officinalis foram testados 11 tratamentos: 1) MSB isento de fitorreguladores; 2) ácido naftalenoacético - ANA (1 μM); 3) ANA (2 μM); 4) a combinados de ANA (1 μM) com Benzilaminopurina - BAP (1 μM); 5) ANA (1 μM) com BAP (4 μM); 6) ANA (2 μM) com BAP (1 μM); 7) ANA (2 μM) com BAP (2 μM); 8) ANA (2 μM) com BAP (4 μM); 9) BAP (1 μM); 10) BAP (2 μM) e; 11) BAP (4 μM). Para promover a proliferação e a regeneração múltiplas de brotos, os calos e as brotações, foram repicados em três diferentes meios de cultura: 1) ANA (2 μM) + BAP (4 μM); 2) MS + ANA (0,1 μM) + BAP (1 μM) e; 3) MS isento de fitorreguladores. Em R. officinalis observou-se que mais de 43,6% dos explantes apresentaram um tipo de contaminação e 30 % destes revelaram a presença de oxidação e a formação de calo e brotos foi de 56,4%, após 5 semanas de cultivo. A permanência de contaminações com bactérias endógenas evidencia a necessidade de uso de antibióticos no meio de cultivo. Além disto, a alta porcentagem de oxidação e necrose das culturas sugere o uso de antioxidantes durantes os subcultivos. Portanto uma das possíveis estratégias para a micropropagação do alecrim é pela via de organogênese direta, pela ocorrência de regeneração de brotos diretamente dos explantes e pela via indireta, com a indução de calo seguida da regeneração de brotos. Em C. sellowiana, a indução e estabelecimento in vitro das culturas foi conduzida em seis tratamentos, com a suplementação ao meio de cultura básico MSB com diferentes combinações de ácido naftalenoacético - ANA (0 e 0,1 μM) combinados com Benzilaminopurina - BAP (0; 0,5 e 1,0 μM). Regeneração e Multiplicação de Brotos. Brotações e culturas nodulares induzidas e estabelecidas in vitro, foram repicadas para promover a proliferação e a regeneração de brotações múltiplas, em dois diferentes meios de cultura básico MSB suplementado com a combinações dos fitorreguladores: 1) ANA (0,1 μM) e BAP (0,5 μM) e; 2) ANA (0,1 μM) e BAP (1,0 μM). Para a regeneração e o alongamento, os brotos foram repicados para frascos tipo conserva (340 ml) em meio de cultura MSB e isento de fitorreguladores. Brotações com 3-5 cm de altura foram retiradas das folhas para evitar a desidratação e imersa em solução de Ácido Indolilbutírico – AIB (50 ppm) para a indução de enraizamento e transferidas para a substratos para promover a aclimatização. O uso do meio de cultura MSB suplementado com ANA (0,1 μM) mais BAP (1,0 μM) promoveu a alta produção de brotos, e o surgimento de culturas do tipo nodular, que posteriormente regeneram em brotações múltiplas. As brotações e estas culturas do tipo nódulos induzidas e estabelecidas in vitro, quando subcultivadas com ANA (0,1 μM) mais BAP (1,0 μM) promoveram uma alta regeneração de brotos. Para a altura (cm) das plantas, as médias mais elevadas foram obtidas nos tratamentos contendo ANA (0,1 μM) e em MS sem a suplementação de fitorreguladores. Enquanto que, a suplementação ao MSB com ANA (0,1 μM) em combinação com BAP resultou em média maior e significativo número médio e micro brotos por explantes. Portanto, a estratégia para a micropropagação da C. sellowiana se caracteriza pelo modelo da organogênese via formação de nódulos como às culturas nodulares

The response surface methodology (RSM) was used to analyze the effect of the mass ratio of oil to solvent and the water content in the solvent, aiming to minimize the losses of neutral oil and maximize the transfer of free fatty acids plus carotenoids preservation. By using appropriate conditions observed in RSM analysis (mass ratio of oil to solvent equal to 0.74 and water content around 6 mass%), the deacidification of palm oil by continuous liquid-liquid extraction was performed in a perforated rotating disc contactor (PRDC). The experimental results indicate that it is possible to obtain refined palm oil with a free acidity lower than 0.1 mass% by continuous liquid-liquid extraction. © 2016 Elsevier B.V.

O uso das medidas provisórias no estado democrático de direito brasileiro
Tese [doutorado) - Universidade Federal de Santa Catarina, Centro de Ciências Jurídicas. Programa de Pós-Graduação em Direito.Análise crítica do uso abusivo das medidas provisórias pelo Poder Executivo brasileiro desde 1988 até o advento da Emenda Constitucional Nº 32/2001, com as conseqüências que isso acarretou ao Estado Democrático de Direito tal qual como configurado pela Constituição Federal de 1988, pela violação de vários princípios constitucionais conformadores deste tipo de Estado. Demonstração das inconstitucionalidades praticadas em colaboração pelos poderes Executivo, Legislativo e Judiciário, pautando-se pela apresentação de exemplos. Apreciação da regulamentação do uso das medidas provisórias feita pela EC 32/01, ressaltando as ainda excessivas possibilidades de lesão do Estado Constitucional e Democrático de Direito Brasileiro por essa espécie normativa
