| Over mid-ocean ridges, the interaction between the currents and the topography gives rise to complex flows, which drive the transport properties of biogeochemical constituents, and especially those associated with hydrothermal vents, thus impacting associated ecosystems. This paper describes the circulation in the rift valley along the Azores sector of the North Mid-Atlantic Ridge, using a combination of in-situ data from several surveys and realistic high-resolution modeling. It confirms the presence of a mean deep current with an up-valley branch intensified along the right inner flank of the valley (looking downstream), and a weaker down-valley branch flowing at shallower depth along the opposite flank. The hydrographic properties of the rift-valley... |

| In order to identify initial factors that can affect shrimp postlarvae survival during larval rearing, three larval rearing facilities from the Caribbean coast of Colombia were samplesd for 71 nauplii batches during 10 months of 1996. For each batch, cualitative variables (origin, transportation mode, presence of bacteria in transport water) and quantitative variables (transportation time and density, physicochemical parameters of the water, proportion of each nauplii stage and of deformed nauplii) were monitored. Water quality and density (nauplii/l) variables were monitored during the whole process of nauplii packing, transport, reception, acclimatization and stocking. To evaluate the relationship between qualitative variables and larval rearing... |

| Based on 25 hours shipboard ADCP measurements across semi-enclosed bay mouth(Kemen Channel), time series of tidal currents over 12 sites, which distribute evenly along the transect, were constructed to improve our understanding of tidal characteristics and residuals in this region. The tidal currents in Kemen Channel were identified as the regular semidiurnal and reversing tidal flows, with its behaviour more like standing waves. Moreover, the flood currents in the lower layers were found to be ahead of that in the upper layers and vice versa for ebb tides. The major of tidal ellipse for M2 constituent was found to be larger close to the southern side of the channel, with its incline also increasing toward the south. The signs of M4 constituent were also... |

| لقد تم تطبيق نموذج حسابي لتمثيل تنقل المياه وتسرب المواد الملوثة في بحيرة بنزرت. يتكون النموذج من ثلاثة أبعاد وهو يأخذ في الحسبان تبادل كميات المياه، الأملاح والطاقة بين البحيرة والبيئة المحيطة بها. وفي هذا النموذج مثالي حسابي لتسرب المواد الملوثة اللاتفاعلية. لقد تم تطبيق النموذج لتمثيل تسرب هذه المواد من موقع في جنوب غرب البحيرة ثم في أهم المواقع حول البحيرة. ولقد استعملت الرياح التي قيست والمد والجزر من البحر. لقد أثبتت النتائج ان المواد الملوثة تتبخر في المياه في خلال بضع ساعات. |

| Nematode species from three intertidal assemblages (St Lawrence Estuary, Quebec, Canada) were studied in order to form an ecological interpretation of three allometric attributes: body width, size spectra, and morphotypes. The three assemblages were characterized by a very similar sediment grain median (Md) but different silt-clay proportions: A1 (upper-tidal level; Md=122 µm; silt=34.8%), A3 (mid-tidal level; Md=182 µm; silt=12.8%), and A5 (lower-tidal level; Md=122 µm; silt=6.8%). Silt-clay proportions were an influential factor in determining the mean nematode body width, used as a morphological discriminant between burrowing and interstitial organisms. A plot of the number of species vs the body width-classes showed two peaks: between 19.3 and 22.6 µm... |

| Based on original trader surveys, this paper examines how agricultural traders operate in Benin and Malawi. Results indicate that the largest transaction costs are search and transport. The use of modern technology is limited. Search methods rely principally on personal visits by the trader, and quality control requires the presence of the trader at the time of purchase. This increases costs, as the trader has to travel a lot, and makes it difficult for trading enterprises to grow. Since enterprises remain very small, personal transport and search time represent a non-negligible share of marketing costs. |

| Rural and urban spaces are usually regarded as “separate” in both development theory and practice. Yet there are myriad links between them. Urban areas, including regional urban centers such as local market towns, provide households with new opportunities to sell goods and services. These opportunities increase household income by employing previously unemployed household resources or because households reallocate household resources so as to take advantage of new, more profitable activities. Links to market towns improve the prices received by rural households because households can benefit from increased demand for their goods or because the larger market is better able to absorb production from rural areas without causing prices to decline. These links... |

| A globalização impôs à grande maioria dos mercados, níveis de especialização focados na eficiência como condição indispensável para sobrevivência. O surgimento desse novo cenário trouxe em seu arcabouço a necessidade de sinergia entre todas as áreas existentes na empresa. As áreas de marketing precisavam estar inteiradas da capacidade de vendas no respectivo departamento, que por sua vez, precisavam ter conhecimento das necessidades de pessoal e com que grau de qualificação, para atender às demandas dos outros departamentos e todos em perfeita sintonia com o departamento de orçamento e gestão. A sinergia, portanto, se tornou vital na maximização da utilidade dos recursos da empresa. Essas características foram fundamentais também nas atividades meio como... |
