| A thick bloom of the marine prymnesiophycean, Phaeocystis globosa was observed in the central Arabian Sea during the summer monsoon period (July-August, 1996). The cells were mostly in colonial form, embedded in gelatinous matrices. The cell diameter was approximately 7 mu m and showed a distinct double feature form. The intensity of the bloom was as high as 3750 x 10(6) cells m(-2) and the carbon content ranged between 33 and 550 mu g L(-1). Almost 90% of the phytoplankton population was composed of P. globosa in the bloom area. Other common forms were chain-forming diatoms like Rhizosolenia spp., Nitzschia spp. and Chaetoreros spp. The photosynthetic pigment chlorophyll a, however did not show any concomitant rise with the bloom intensity probably... |

| The notion of indirect separability is exploited to derive a new multistage demand system. The model allows a consistent parameterization of demand relations at various budgeting stages and it fulfills the requirement of flexibility while satisfying separability globally. Two propositions are derived to characterize flexible and separable functional forms, which lead to the specification of a flexible and separable translog (FAST) demand system. The model is particularly attractive for modeling large complete demand systems, and is illustrated with an application to Canadian food demand. |

| Demand for healthy, safe and environmentally friendly food products has been increasing. In response, producers are marketing organic and other quality-differentiated foods, sometimes claiming to have followed sound environmental and animal welfare practices. These products frequently have unobservable quality attributes. If the profit-maximizing producer is able to deceive the consumer with a false claim, then he or she will enjoy a higher price with lower production costs (compared to the full disclosure outcomes). The analysis described in this paper shows that repeat-purchase relationships and third party monitoring are required for high-quality credence goods to be available. Policy implications of this analysis for national organic food standards are... |

| Huff and Hertel (2001) derive a welfare decomposition for the equivalent variation in the GTAP model. The derivation appears to be very specific to GTAP. Nevertheless, it contains nearly all the ingredients required for performing welfare decomposition for any CGE model. In this paper, the approach of Huff and Hertel (2001) is generalised to derive a welfare decomposition that can be applied to most, if not all, CGE models. General production and utility functions are accommodated, as are foreign income flows. A brief guide to coding the proposed welfare decomposition in GEMPACK is also provided. The decomposition is applied to decomposing the equivalent variation in GTAP. |

| A gueroba, gariroba ou guariroba e uma palmeira arborea nativa do bioma Cerrado que produz frutos com polpa mucilaginosa comestivel e palmito amargo muito utilizado no cardapio regional e comercializado in natura nas feiras e margens de rodovias. O extrativismo intenso para uso do palmito vem reduzindo substancialmente os guerobais nativos. Dai, este trabalho tratar de parte de um estudo de caso dessa planta, na Fazenda Pantanal dos Buritis em Aragoiania, GO. O enfoque geral deste estudo, e mostrar seu comportamento em cultivo, destacando as mais variadas maneiras de utilizar suas partes para reduzir desperdicios. Neste trabalho, sao abordados desde a descricao botanica, colheita e secagem dos cocos-semente, problemas de germinacao e desenvolvimento... |

| A gueroba, guariroba ou gariroba e uma palmeira importante para a populacao do Cerrado, sendo extraido dela um palmito de sabor amargo muito apreciado na culinaria regional. Esse produto e comercializado, geralmente, in natura e sua industrializacao ainda e artesanal. Seu principal mercado localiza-se nos Estados de Goias, Tocantins, Mato Grosso, Mato Grosso do Sul, algumas regoes da Bahia e de Minas Gerais e no Distrito Federal. Com a exploracao predatoria e a acelerada destruicao da vegetacao nativa por meio da expansao da fronteira agricola, a oferta do produto, oriunda do extrativismo, vem sendo reduzida substancialmente. No entanto, tem-se observado o cultivo dessa palmeira em alguns Estados, principalmente em Goias que, em 1999, cultivava 4.499... |

| Insulin stimulates the tyrosine kinase activity of its receptor resulting in the tyrosine phosphorylation of pp185, which contains insulin receptor substrates IRS-1 and IRS-2. These early steps in insulin action are essential for the metabolic effects of insulin. Feeding animals a high-fructose diet results in insulin resistance. However, the exact molecular mechanism underlying this effect is unknown. In the present study, we determined the levels and phosphorylation status of the insulin receptor and pp185 (IRS-1/2) in liver and muscle of rats submitted to a high-fructose diet evaluated by immunoblotting with specific antibodies. Feeding fructose (28 days) induced a discrete insulin resistance, as demonstrated by the insulin tolerance test. Plasma... |

| O ganho de peso diário, principalmente da desmama aos doze meses, é geralmente utilizado nos programas de melhoramento genético de bovinos de corte. Entretanto, as análises de dados do desenvolvimento ponderal de bovinos da raça Canchim, oriundos da Embrapa Pecuária Sudeste, São Carlos, SP e de zebuínos das raças Nelore, Tabapuã, Gir, Indubrasil e Guzerá, controlados pela Associação Brasileira de Criadores de Zebu (ABCZ), mostraram que esta característica deve ser usada com cautela pelos melhoristas. Alguns resultados evidenciam essa preocupação: a) na análise de dados do peso à desmama e aos doze meses de idade de animais Canchim e do ganho de peso diário entre essas idades, a combinação dessas três características por meio de índice mostrou que o peso... |
