| The purpose of this paper is to determine if hedging effectiveness can be enhanced with an understanding of seasonal and interseasonal changes in relative prices between the three wheat futures markets. The specific objectives of the analysis are to address the following questions: (1) What factors have contributed to increased variability in relative prices? (2)Do seasonal patterns in relative prices exist, and if so, how reliable is such seasonality? (3)How can hard red spring wheat hedgers use changing price spreads to increase the effectiveness of their hedging programs? (4) Can fundamental factors of supply and demand be used to predict forthcoming relative prices, and thus guide hedgers in selection of the most advantageous hedging market? |

| Annual or perennial herbs, rarely shrubs, with hollow stems. Leaves alternate or rarely opposite, simple or variously compound; petioles usually sheathing at the base. Stipules minute or wanting. Inflorescence consisting of many-flowered, simple or compound umbels, heads or spikes; umbels and umbellules often involucrate. Flowers hermaphrodite or polygamous, actinomorphic or subzygomorphic, epigynous. Calyx of small teeth around the upper edge of the ovary or wanting. Petals 5, the apex often inflexed, valvate, sometimes wanting. Stamens 5; filaments inserted below the stylopodium (disk); anthers versatile. Ovary inferior, 2-locular, crowned by a conspicuous stylopodium; styles 2, free; stigmas small. Ovules solitary in each locule, pendulous, anatropous.... |

| An econometric model of U.S. and Maine apple production and prices was estimated with ordinary least squares multiple regression. A Gauss-Seidel solution technique was used to examine the equation system goodness of fit and to forecast endogenous variable values. Results indicate that supply expansion in the U.S. and Maine will continue, but Maine's slower rate of increase will erode its market share. Apple prices for the U.S. and Maine are predicted to decline in real terms by the year 2000 if inflation rates exceed 3 percent annually during the period 1982 to 2000. |

| Au cours des deux dernières décennies, l'accent a été mis, par la communauté scientifique internationale, sur l'importance des interactions océan-atmosphère dans la genèse des phénomènes météorologiques, et sur la nécessité d'améliorer le réseau d'observations en mer : Les bouées dérivantes ou ancrées, porteuses de stations automatiques de mesures, sont à l'heure actuelle largement utilisées par les organismes météorologiques, pour combler les zones où les informations font défaut. La localisation de ces bouées, et la transmission des données sont assurées par le système ARGOS, système embarqué à bord de satellites à orbites polaires. |

| Avaliou-se a variação de peso de bovinos alimentados com silagem de sorgo (Sorghum bicolor (L.) Moench) e suplementados com vagens de faveira (Parkia playtycephala Benth) inteiras e moidas. Foram utilizados 3 grupos de 5 bezeros, mestiços de zebu x holandês, com idade de 10 a 14 meses e peso vivo medio inicial de 175+-31 kg/animal. Os animais foram confinados em baias individuais, distribuidos ao acaso, tendo a disposição os alimentos, água e sal mineral. O primeiro grupo de animais recebeu somente silagem; o segundo, silagem mais vagens inteiras;e o terceiro, silagem mais vagens moidas. A duração do trabalho foi de 106 dias, sendo o periodo inicial de 22 dias, considerados de adaptação, e os 84 dias seguintes como de coleta de dados. Os animais foram... |

| Monoecious, medium-sized to very large trees (rarely shrubby in very exposed situations). Either four independent cotyledons or two fused pairs (which may be retained in the seed after germination). The growing point of foliage shoots quite distinct between the two genera, being just a few highly reduced leaves in Araucaria and a highly organized bud formed of overlapping scales in Agathis. The leaves vary from scales or needles to broad leathery forms with many parallel veins sometimes on the same plant at different stages of growth. Pollen produced in cylindrical cones from one to as much as twenty cm long with numerous pedunculate spirally placed microsporophylls each with several to many pendent elongated pollen sacs attached to the lower side of an... |
