1. Properties of Cu-Co Composite Catalysts for Synthesis of Aliphatic Alcohols
Cu-Co-containing cellulose-based carbon composite materials (Cu-Co/Cel) were formed by a matrix isolation method. Using X-ray diffraction (XRD), transmission electron microscopy (TEM), infrared-Fourier spectroscopy (IR-Fourier spectroscopy), and non-isothermal research methods, the physicochemical properties of the composites were established. The catalysts

2. Development and Validation of a Stability-Indicating Method for Perillyl Alcohol Incorporated in Poly(lactide-co-glycolide) Nanoparticles and Stress Degradation Studies
Perillyl alcohol has been studied in the treatment of cancer disease. However, its high toxicity is a drawback, which can be overcome by its incorporation in nanostructured systems. The aim of this work was to develop and validate a chromatographic method for determination of perillyl alcohol encapsulation efficiency in a polymeric nanoparticles formulation

4. The determinants of sugar and alcohol supply in Paranà State (1981 to 2006): an analysis of cointegration / Determinantes das ofertas de aÃÃcar e de Ãlcool paranaenses (1981 a 2006): uma anÃlise de co-integraÃÃo
The beginning of 90s is marked by a new dynamic of Brazilian sugar cane agribusiness. The disconnection of the State apparatus, which was responsible for the activities management at that time, forced the sector to an adjustment in a free market context that, since then, has been experiencing significant advances, both in internal and external markets. The i

5. AvaliaÃÃo do impacto do uso de agrotÃxicos nos trabalhadores rurais dos MunicÃpios de Ribeiro GonÃalves, Baixa Grande do Ribeiro e UruÃuà â Piauà / Evaluation of the Impact of the use of Pesticides on Agricultural Laborersâ Health in the Cities of UruÃuÃ, Ribeiro GonÃalves and Baixa Grande do Ribeiro
The pesticides are some of the main risky factors for agricultural laborersâ health. In the state of PiauÃ, the agricultural expansion which was implemented in the cerrados through the growth of the soy crops in the 90âs was a relevant factor that increased the use of pesticides. The unbalanced usage of pesticides is often related to acute and chronic poi

6. Análise de ecoeficiência: avaliação do desempenho econômico-ambiental do biodiesel e petrodiesel. / Eco-efficiency analysis: environmental-economic assessment of biodiesel and petrodiesel.
Biodiesel is the most likely alternative to petrodiesel. It is composed of methyl or ethyl esters from fatty acids, obtained by a transesterification reaction between any triglycerides and an alcohol with short chain, methanol or ethanol. It has almost the same properties of petrodiesel, but comparing with this, it can eliminate the sulfur oxides emissions a

7. "Dependence of the selectivity of the methanol and ethanol electrooxidation reaction on Pt/C and PtRh/C nanoparticles" / "Dependência da seletividade da reação de eletro-oxidação de metanol e etanol sobre nanopartículas de Pt/C e PtRh/C"
The methanol and ethanol electrooxidation is a subject of intense studies in electrocatalysis. The aim of such attention concerning this alcohol electrooxidation activity is due to development of new energy converter systems more efficient and less pollutant. The electrocatalysis research has been also directed to nanoparticle systems. Metallic particles in

8. Psychosis and cannabis
Alcohol and cannabis misuse is currently the most frequent co-morbidity disorder of schizophrenia. The following four issues will be dealt with: 1) the neurobiological basis of the psychosis-inducing, pathogenic effects of THC, the agent contained in cannabis products. 2) Can cannabis use - and for comparison alcohol abuse - prematurely trigger or even cause

9. Quantificação e efeitos econômicos do controle de emissões de CO2 decorrentes do uso de gás natural, álcool e derivados de petróleo no Brasil: um modelo interregional de insumo-produto / Quantification and economic effects of the control of CO2 emissions from natural gas, alcohol and oil derived products in Brazil: an interregional input-output model
This work quantifies the CO2 emissions from energy use of natural gas, alcohol and oil derived products at a national and regional level and evaluates the impacts of eventual policies for emissions control. The results pointed the connection between the activity level and the emissions of CO2 for each energy input considered for Brazil as a whole and for its

10. Study of the stability of sliced cooked ham in modified atmosphere. / Estudo da estabilidade de presunto cozido fatiado em atmosfera modificada.
The purpose of this study was to evaluate the efficiency of packaging systems with modified atmosphere to preserve the quality of sliced cooked ham. Thus the quality stability of the product at 4 +/_:t 1°C, packed in a gas barrier package with three kinds of modified atmosphere (100% CO2, 60% CO2/40% N2 and 25% CO2 I 75% N2), was studied. The shelf-life of

12. Projeto de catalisadores para reações com gas de sintese
A partir do gás de síntese (que constitui uma mistura gasosa de óxidos de carbono e hidrogênio), pode-se obter hidrocarbonetos, álcoois e aldeídos. Estes podem ser obtidos também através da via petroquímica. Portanto, a produção desses compostos a partir do gás de síntese constituem vias alternativas que podem ser exploradas em função de aspec
