| A apicultura piauiense assume grande importância socioeconômica e ecológica, haja vista que milhares de famílias estão direta e indiretamente envolvidas nos elos da produção e do processamente na cadeia dos produtos apícolas, ao mesmo tempo em que, por ser uma atividade com características próprias de agricultores e familiares, com rentabilidade superior à maioria das atividades agropecuárias exercidas por esses mesmos agricultores, vem cumprindo papel importante na fixação dos homens e mulheres (especialmente dos jovens) no meio rural. Portanto, atividade apícola desenvolvida no Piauí apresenta-se como um bom exemplo no contexto da multiplicidade de formas de geração de dinâmicas econômicas no meio rural. |

| A case study of the effects of ship emissions on the microphysical, radiative, and chemical properties of polluted marine boundary layer clouds is presented. Two ship tracks are discussed in detail. <i>In situ</i> measurements of cloud drop size distributions, liquid water content, and cloud radiative properties, as well as aerosol size distributions (outside-cloud, interstitial, and cloud droplet residual particles) and aerosol chemistry, are presented. These are related to remotely sensed measurements of cloud radiative properties. The authors examine the processes behind ship track formation in a polluted marine boundary layer as an example of the effects of anthropogenic particulate pollution on the albedo of marine stratiform clouds. |

| The effects of anthropogenic particulate emissions from ships on the radiative, microphysical, and chemical properties of m(oderately polluted marine stratiform clouds are examined. A case study of two ships in the same air mass is presented where one of the vessels caused a discernible ship track while the other did not. <i>In situ</i> measurements of cloud droplet size distributions, liquid water content, and cloud radiative properties, as well as aerosol size distributions (outside cloud, interstitial, and cloud droplet residual particles) and aerosol chemistry, are presented. These are related to measurements of cloud radiative properties. The differences between the aerosol in the two ship plumes are discussed; these indicate that... |

| Collaboration among multiple stakeholders can be crucial to the success of natural resource management. In recent years, a wide variety of methods have been developed to facilitate such collaboration. Because these methods are relatively new and come from different disciplines, little attention has been paid to drawing comparisons among them. Thus, it is very difficult for potential users to sort through the increasingly large literature regarding such methods. We suggest the use of a consistent framework for comparing collaborative management methods, and develop such a framework based on five criteria: participation, institutional analysis, simplification of the natural resource, spatial scale, and stages in the process of natural resource management. We... |

| O presente trabalho teve por objetivo avaliar a influência da cobertura vegetal de inverno, constituída de uma associação de aveia preta (Avena strigosa Schreb) com nabo forrageiro (Raphanus sativus L.), da adubação orgânica com esterco de aves e da adubação mineral sobre o rendimento de grãos da sucessão feijão/milho numa Terra Roxa Estruturada do estado de Santa Catarina. A cobertura do solo influenciou o rendimento de grãos de feijão, mas não o de milho. Isto pode ser atribuído à produção de uma safra de feijão antes do estabelecimento da cultura do milho e ao fato de a associação de aveia preta com nabo forrageiro apresentar uma relação C/N mais estreita que a da aveia. Independentemente do uso da cobertura vegetal, a prática da adubação promoveu... |

| The MEDATLAS hydrological data base, has been created by a consortium of several data centers, including HNODC (Greece), IEO (Spain), EPSHOM/CMO (French navy), IFREMERJSISMER the coordinating center (France) and ICES (Denmark) as the supervisor of the quality control procedure, in the frame of the MEDATLAS project. This project is a MAST supporting initiative for ocean data and information management. Its objectives were to assemble a comprehensive data base of temperature and salinity profiles collected in the Mediterranean sea by t he scientific laboratories and the navies, to check them for quality and to revise the climatological statistics by using this updated date set. An important part of the work has been devoted to define a common protocol to... |

| In the present study the age-related changes of the striated muscle elastic fiber system were investigated in the diaphragm and rectus abdominis muscles of 1-, 4-, 8- and 18-month-old rats. The activation patterns of these muscles differ in that the diaphragm is regularly mobilized tens of times every minute during the entire life of the animal whereas the rectus abdominis, although mobilized in respiration, is much less and more irregularly activated. The elastic fibers were stained by the Verhoeff technique for mature elastic fibers. Weigert stain was used to stain mature and elaunin elastic fibers, and Weigert-oxone to stain mature, elaunin and oxytalan elastic fibers. The density of mature and elaunin elastic fibers showed a progressive increase with... |

| Four different programming models dealing with the agricultural sectors in Canada, The Netherlands, Sweden and Denmark are analysed. The purpose is to construct a knowledge base for the development of a new sector model for Danish agriculture. This analysis has created a valuable set of resources for use in the development of the model. |

| In an endeavour to improve the livestock production and particularly the marketing of livestock in the Northern Communal Areas of Namibia, this study analyses the perception of livestock farmers in this regard. The findings show that the decision making is significantly influenced by numerous socio-cultural considerations, which in many cases even overshadow the economic ones. This is manifested in the low off-take percentage, the lacking interest in commercial production, and the fact that the sale price offered to the farmer is not the most important consideration when deciding to whom to sell. |
