    Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) Biofuels have great importance to supply the global energy demand. These fuels are produced from plant biomass, emit less carbon dioxide and particulate pollutants to the environment when used and have great advantage of being renewable fuels. Among the raw materials with potential for ethanol production, is cited sweet sorghum. This study aimed to compare industrial processing of genotype sorghum CVSW80007 and the cultivar sugar cane 'RB966928' for bioethanol production in early season. The analyzes performed were: brix, pH, ART, AR, total acidity, ARRT, glycerol, alcohol content, cell viability, shoots viability and buds. Regarding the chemical-technological characteristics, raw materials were suitable for industrial processing, with higher rates for sugar cane. The development of fermentations occurred appropriately for both, and the fermented must (wine) produced from the must of sugar cane had higher alcohol content and fermentation yield. Os biocombustíveis apresentam-se com grande importância para suprir a demanda global de energia. São produzidos a partir de biomassa vegetal, emitem menor quantidade de dióxido de carbono e de partículas poluentes ao ambiente quando utilizados e possuem grande vantagem por serem combustíveis renováveis. Entre as matérias-primas com potencial para produção de etanol, cita-se o sorgo sacarino. Objetivou-se comparar o processamento industrial do genótipo de sorgo sacarino CVSW80007 e da cultivar de cana-de-açúcar 'RB966928' para produção de bioetanol em início de safra. As análises realizadas foram: brix; pH, ART, AR, acidez total, ARRT, glicerol, teor alcoolico, viabilidade celular, viabilidade de brotos e brotamentos. Quanto às características químico-tecnológicas, as matérias-primas apresentaram-se aptas ao processamento industrial, com índices superiores para a cana-de-açúcar. O desenvolvimento das fermentações ocorreu de forma adequada para ambas, sendo que o mosto fermentado (vinho), produzido a partir do mosto de cana-de-açúcar, apresentou maior teor alcoolico e rendimento fermentativo.

    O metabolismo vegetal sofre alterações com o aumento da concentração de CO2na atmosfera terrestre. Inicialmente, a taxa fotossintética aumenta pela maior disponibilidade de CO2, após determinado tempo de exposição, observa-se algumas adaptações a fim de retornar ao equilíbrio inicial, caracterizando a aclimatação. O objetivo desta revisão foi descrever os mecanismos responsáveis pela aclimatação das plantas à elevada concentração de CO2 na atmosfera. Num curto prazo, enzimas e outras substâncias importantes para a fotossíntese começam a ficar escassas pelo metabolismo acelerado. Além disso, o amido excedente da elevada taxa fotossintética acumula-se no interior de cloroplastos, podendo prejudicar a fotossíntese. Num período mais longo de exposição, observa-se um decréscimo da vantagem produtiva do ambiente com elevado CO2e uma distribuição da biomassa, que favorece as partes vegetativas. A aclimatação no longo prazo está relacionada com a capacidade de o vegetal aumentar seus compartimentos de armazenamento. The plant metabolism is altered with increasing of CO2concentration in the atmosphere. Initially the photosynthetic rate increases by the greater CO2available, after some time there is some adaptations in order to return to the initial equilibrium, characterizing acclimation. The objective of this review was to describe the acclimation mechanisms in plants to elevated CO2concentration. In the short term, enzymes and other important substances for photosynthesis are scarce by accelerated metabolism. In addition, excess starch of high photosynthetic rate, accumulated within chloroplasts can impair photosynthesis. A longer period there is a decrease in productive advantage on high CO2environment and biomass distribution that favors vegetative parts. Acclimation in the long term is related to the plant ability to increase its storage compartments.

    Com o objetivo de avaliar as características de distribuição de agentes hiperbáricos no líquido cérebro-espinhal (LCE) eqüino, é apresentado um modelo in vitro do espaço subaracnóide confeccionado em policloreto de vinila (PVC) transparente, no qual se adaptou um cateter para a infusão contínua de glicose a 10%, morfina hiperbárica, buprenorfina hiperbárica e metadona hiperbárica marcadas com azul de metileno para permitir a visualização da distribuição destas substâncias no LCE. Avaliaram-se a distância alcançada pelos diferentes agentes minuto a minuto e a forma de distribuição dos mesmos. Todas as substâncias testadas mostraram comportamento de distribuição vertical a partir da extremidade do cateter, quando se deu o início da migração cranial no LCE, sendo que o avanço máximo registrado foi aos 15 minutos após o término da infusão, com migração de 15cm para glicose a 10%, 13cm para a morfina hiperbárica, 18cm para a buprenorfina hiperbárica e 17cm para a metadona hiperbárica. O modelo proposto mostrou-se eficiente para a avaliação do comportamento físico dos agentes hiperbáricos no interior do espaço subaracnóide, oferecendo a possibilidade de teste de substâncias a serem utilizadas pela via subaracnóide de cavalos.The aim of this study was to evaluate the distribution characteristics of hyperbaric solutions in equine cerebrospinal fluid (CSF), in an in vitro model of the subarachnoid space. The model was made with transparent PVC in which a catheter was adapted to infuse 10% glucose, 10% hyperbaric morphine, hyperbaric buprenorphine, and hyperbaric methadone, dyed with methilene blue in order to visualize the solutions distribution in the CSF. The distance in cm reached by the different agents every minute as well as the pattern of distribution were evaluated. All tested solutions distributed itself in a forward and vertically pattern from the tip of the catheter. Maximum distance reached after 15 minutes were 15cm for 10% glucose, 13cm for hyperbaric morphine, 18cm for hyperbaric buprenorphine, and 17cm for hyperbaric methadone. The proposed model was efficient to evaluate the distribution pattern of hyperbaric solutions in equine CSF, offering a new possibility to physically test the administration of solutions in the equine subarachnoid space.

    Com o objetivo de avaliar as características de distribuição de agentes hiperbáricos no líquido cérebro-espinhal (LCE) eqüino, é apresentado um modelo in vitro do espaço subaracnóide confeccionado em policloreto de vinila (PVC) transparente, no qual se adaptou um cateter para a infusão contínua de glicose a 10%, morfina hiperbárica, buprenorfina hiperbárica e metadona hiperbárica marcadas com azul de metileno para permitir a visualização da distribuição destas substâncias no LCE. Avaliaram-se a distância alcançada pelos diferentes agentes minuto a minuto e a forma de distribuição dos mesmos. Todas as substâncias testadas mostraram comportamento de distribuição vertical a partir da extremidade do cateter, quando se deu o início da migração cranial no LCE, sendo que o avanço máximo registrado foi aos 15 minutos após o término da infusão, com migração de 15cm para glicose a 10%, 13cm para a morfina hiperbárica, 18cm para a buprenorfina hiperbárica e 17cm para a metadona hiperbárica. O modelo proposto mostrou-se eficiente para a avaliação do comportamento físico dos agentes hiperbáricos no interior do espaço subaracnóide, oferecendo a possibilidade de teste de substâncias a serem utilizadas pela via subaracnóide de cavalos.The aim of this study was to evaluate the distribution characteristics of hyperbaric solutions in equine cerebrospinal fluid (CSF), in an in vitro model of the subarachnoid space. The model was made with transparent PVC in which a catheter was adapted to infuse 10% glucose, 10% hyperbaric morphine, hyperbaric buprenorphine, and hyperbaric methadone, dyed with methilene blue in order to visualize the solutions distribution in the CSF. The distance in cm reached by the different agents every minute as well as the pattern of distribution were evaluated. All tested solutions distributed itself in a forward and vertically pattern from the tip of the catheter. Maximum distance reached after 15 minutes were 15cm for 10% glucose, 13cm for hyperbaric morphine, 18cm for hyperbaric buprenorphine, and 17cm for hyperbaric methadone. The proposed model was efficient to evaluate the distribution pattern of hyperbaric solutions in equine CSF, offering a new possibility to physically test the administration of solutions in the equine subarachnoid space.
