| This report evaluates the United States and world corn and soybean markets for the 2009-2019 time period using the Global Corn and Soybean Policy Simulation Model. This analysis is based on a series of assumptions about general economic conditions, agricultural policies, weather conditions, and technological change. The major influence in the corn market will be U.S. corn based ethanol production. If the production of corn based ethanol remains strong, corn prices will likely remain strong. However, if the U.S. Federal government subsidies or mandates change, the world corn market could be negatively impacted. Under the current assumptions in the model, corn price is expected to remain in a range between $3.70 and $4.10 per bushel. The level of Chinese... |

| Traffic flows in the U.S. have been affected by the substantial increase and, as of January 2009, decrease in biofuel production and use. This paper considers a framework to study the effect on grain transportation flows of the 2005 Energy Act and subsequent legislation, which mandated higher production levels of biofuels, e.g. ethanol and biodiesels. Future research will incorporate changes due to the recent economic slowdown. |

| Acetaldehyde (AAld) is a ubiquitous compound in the environment. Exposure may occur in its manufacture or use, in the consumption of alcoholic beverages and through cigarette smoke. It causes distant target effects, including DNA damage, glutathione depletion, enzyme inactivation and cell death. In the present work, its potential teratogenic, mutagenic and recombinagenic effects in somatic cells of D. melanogaster were analyzed. The white/white+ (w/w+) eye mosaic test (Somatic Mutation And Recombination Test, SMART) was applied by mating w/w females with y/Y males. Larvae of 48 ± 4 h were transferred to media with 0.01 %, 0.02 %, 0.05 % and 0.10 % AAld for 12 hs and then moved to regular media until pupation. The emerging w/w+ females were evaluated for... |

| Analysis of the potential to supply 25% of projected 2025 U.S. transportation fuels indicates sufficient biomass resources are available to meet increased demand while simultaneously meeting food, feed, and export needs. Corn and soybeans continue to be important feedstocks for ethanol and biodiesel production, but cellulose feedstocks (agricultural crop residues, energy crops such as switchgrass, and forestry residues) will play a major role. Farm income increases, mostly because of higher crop prices. Increased crop prices increase the cost of producing biofuels. |

| The objective of the present experiment was to assess ethyl alcohol (ETOH) dependence brought about by a semivoluntary intermittent intake regimen in rats. Male Wistar rats weighing 150-250 g at the onset of the experiment were assigned to the following groups: 0% ETOH (N = 11), 5% ETOH (N = 20), 20% ETOH (N = 20) and 40% ETOH (N = 18). ETOH solutions were offered at the end of the day and overnight from Monday to Friday, and throughout weekends, for 90 days. The concentration of the ETOH solutions was increased in a stepwise fashion allowing the rats to get used to the taste of alcohol. Reposition of pure water was permitted during 1-h water drinking periods in the morning. Daily volume intake (± SEM) averaged 25.4 ± 0.4 ml (0% ETOH), 23.8 ± 0.6 ml (5%... |

| A global multi-commodity simulation model was developed to estimate the impact of changes in ethanol production on the U.S. corn industry. Increased ethanol production under the Energy Acts of 2005 and 2007 resulted in a significant increase in the price of corn. However, for corn-based ethanol production, the break-even price of corn is approximately $4.52 per bushel with a federal subsidy of $0.51 per gallon of pure ethanol and $2.50 gasoline. With a corn price of $4.52, the economically desirable ethanol production is approximately 11 billion gallons. In order to produce 15 billion gallons of corn-based ethanol and to maintain the price of corn at $4.52 per bushel, supply of corn in the U.S. should be increased substantially through increases in corn... |

| The US Environmental Protection Agency announced a waiver allowing an increase in the Fuel-Ethanol blend limit (the “blend wall” ) from 10% (E10) to 15% (E15) on October,2010.Justifications for the waiver are reduced vehicle fuel prices and less consumption of petroleum gasoline, leading to energy security. In this paper, employing Monte Carlo simulations and Savitzky-Golay smoothing filter, an empirical study examines this waiver revealing an anomaly where a relaxation of this blend wall elicits a demand response. Under a wide range of elasticities, this demand response can actually increase the consumption of petroleum gasoline and thus lead to greater energy insecurity. The economics supporting this result and associated policy implications are... |

| Mauritia vinifera (buriti) is a palm tree that grows wild in different areas of Brazil, particularly in the Amazonian region. The buriti oil is rich in carotenoids, especially in β-carotene. The growing interest in other natural sources of β-carotene has stimulated the industrial use of buriti as a raw material for pulp oil extraction. Most processes are based on the conventional technologies, involving drying and pressing the pulp for oil recovery and further separation of carotenoids in a liquid phase using organics solvents. In the present work, the ethanol-based process was evaluated for simultaneous carotenoids recovering and fractionating from buriti pulp. The raw material and ethanol, 1:4 ratio, were placed in an erlenmeyer flask and maintained at... |

| We investigated whether liver injury by dual exposure to ethanol and carbon tetrachloride (EtOH + CCl4) for 15 weeks would persist after hepatotoxic agents were removed (EtOH + CCl4/8wR). After 15 weeks of hepatic injury with ethanol (5.5%, m/v) and carbon tetrachloride (0.05, mL/kg, ip), 5 of 11 female Wistar rats were sacrificed. The other 6 rats were maintained for an additional 8 weeks without hepatotoxic agents. Ultrasonography showed increased liver echogenicity and dilation of portal vein caliber in both groups (EtOH + CCl4: 0.22 ± 0.01 cm, P < 0.001; EtOH + CCl4/8wR: 0.21 ± 0.02 cm, P < 0.01) vs control (0.16 ± 0.02 cm). Histopathology showed regenerative nodules in both experimental groups. Histomorphometry revealed increased fibrosis... |

| This aim of this article is to analyze the relation of size and operational efficiency of sugar and ethanol plants in the northeastern region of São Paulo state. In order to achieve this goal, a survey was conducted to identify the consumption of the main resources (inputs) and product creation (outputs) in a random sample of twenty six units, which allowed for their classification according to size. This enabled the creation of an efficiency ranking, using Data Envelopment Analysis (DEA), whose variables were chosen by the stepwise method. The results suggest that, for the plants studied, there is no direct relation between size and operational efficiency, which can be explained by technical aspects associated to the inputs. The results provide subsides... |
