| In this article, we will review some behavioral, pharmacological and neurochemical studies from our laboratory on mice, which might contribute to our understanding of the complex processes of memory consolidation and reconsolidation. We discuss the post-training (memory consolidation) and post-reactivation (memory reconsolidation) effects of icv infusions of hemicholinium, a central inhibitor of acetylcholine synthesis, of intraperitoneal administration of L-NAME, a non-specific inhibitor of nitric oxide synthase, of intrahippocampal injections of an inhibitor of the transcription factor NF-κB, and the exposure of mice to a new learning situation on retention performance of an inhibitory avoidance response. All treatments impair long-term memory... |

| Mixed sediments are constituted of cohesive and non-cohesive materials with distinct behaviours that numerical models traditionally manage separately. This paper first introduces a rapid state of the Art in sediment transport modelling in order to point out the specific requirements for process-based models applied to mixed sediments. Based on a preliminary study by Waeles et al. (2007), which showed the validity of the advection approach to compute fine sand transport, a complete modelling strategy is described: it is applied to the suspended transport of sand and mud mixtures, and accounts for consolidation of mixed sediments. Special care is paid to the realistic representation of the structure and density of sand and mud mixtures, and to the... |

| Sediment transport modelling in estuarine environments, characterised by cohesive and non-cohesive sediment mixtures, has to consider a time variation of erodibility due to consolidation. Generally, validated by settling column experiments, mud consolidation is now fairly well simulated; however, numerical models still have difficulty to simulate accurately the sedimentation and consolidation of mixed sediments for a wide range of initial conditions. This is partly due to the difficulty to formulate the contribution of sand in the hindered settling regime when segregation does not clearly occur. Based on extensive settling experiments with mud-sand mixtures, the objective of this study was to improve the numerical modelling of mixed-sediment consolidation... |

| The sediment characteristics of hydrate-bearing reservoirs profoundly affect the formation, distribution, and morphology of gas hydrate. The presence and type of gas, porewater chemistry, fluid migration, and subbottom temperature may govern the hydrate formation process, but it is the host sediment that commonly dictates final hydrate habit, and whether hydrate may be economically developed. In this paper, the physical properties of hydrate-bearing regions offshore eastern India (Krishna-Godavari and Mahanadi Basins) and the Andaman Islands, determined from Expedition NGHP-01 cores, are compared to each other, well logs, and published results of other hydrate reservoirs. Properties from the hydrate-free Kerala-Konkan basin off the west coast of India are... |

| This report focuses on recent trends in the food supply chain. Chapters on food manufacturing, wholesaling, grocery retailing, and food service provide a detailed overview of structure, performance, information systems, new technology, and foreign direct investments. The report also contains a comprehensive set of appendix tables containing sales, concentration, trade, productivity, and other indicators. At the time of publication, most of the data sets used in this report included data through the year 2000. |

| Consolidation and structural changes in the food industry have had profound impacts on firms, employees, and communities in many parts of the United States. Over 1972-92, eight important food industries underwent a structural transformation in which the number of plants declined by about one-third and the number of employees needed to staff the remaining plants dropped by more than 100,000 (20 percent). The number of plants in one other industry also dropped, but that industry added jobs. Economists generally attribute structural changes such as these to rising or falling demand and shifts in technology. This report examines consolidation and structural change in meatpacking, meat processing, poultry slaughter and processing, cheese products, fluid milk,... |

| The grain/oilseed industry is undergoing considerable structural change in the form of mergers and the addition of new processing facilities to add value beyond commodity grade. The rapid structural changes in this industry call into question the relevance of previous research conducted in these areas. Focusing on two structural change events in northeast Missouri as case studies provides an incisive glimpse at the larger impact of structural change on the grain/oilseed industry. This study addresses the merger of Archer Daniels Midland and Quincy Grain, and the opening of a producer-owned ethanol plant in northeast Missouri to determine if these structural change events altered pricing patterns and linkages in Missouri grain/oilseed markets, and assess... |

| Despite extensive research and policy initiatives to increase the technical, financial, and managerial capacity of small drinking water systems, there has been little research focusing on understanding how consolidation can increase the overall capacity of the drinking water industry. Consolidation of water systems may be a mechanism that increases regulatory compliance by removing poorly performing systems from the industry and replacing inefficient management and/or capital. The US drinking water system is highly fragmented, with over 50,000 Community Water Systems (CWSs), of which the vast majority are classified as "small" by the US Environmental Protection Agency (EPA). A discrete choice model is employed to determine the characteristics shared by... |

| This paper examines the impact of farmland readjustment projects on farmland use and structural adjustment in Niigata, Japan. We use census data of rural communities for 1990 and 2000 to conduct pooled regression, first-difference, difference-in-differences, and propensity score matching estimations. We find positive impact of farmland readjustment projects in alleviating farmland abandonment and in facilitating outsourcing of agricultural works and farmland rental. The results suggest that farmland consolidation may be an effective option to resolve farmland fragmentation and to promote structural adjustment in concentrating farmland to efficient farmers which is a premise for strengthening the agricultural sector under economies of scale. |

| Napjainkban a világgazdaság egyik legfontosabb megoldásra váró problémája, hogy hogyan előzhető meg újabb globális pénzügyi és gazdasági válságok kialakulása, illetve léteznek-e olyan módszerek, eszközök, amelyek segítségével a már kialakult válságok hatásai, következményei mérsékelhetők. A módszerek, eszközök részben már rendelkezésre állnak, melyek közül célszerű kiemelni a konszern számvitel módszertanát, mert segítségével elkészíthető konszolidált éves beszámolót. E konszolidált éves beszámoló ugyanis alkalmas arra, hogy a konszerntagok közötti belső kapcsolatokból adódó halmozódásokat kiszűrve előmozdítsa a vállalatcsoportok reális megítélését. Segítségével elkerülhetővé válhat a – válság kialakulásában nagymértékben szerepet játszó – jogi, pénzügyi... |

| Meatpacking consolidated rapidly in the last two decades: slaughter plants became much larger, and concentration increased as smaller firms left the industry. We use establishment-based data from the U.S. Census Bureau to describe consolidation and to identify the roles of scale economies and technological change in driving consolidation. Through the 1970's, larger plants paid higher wages, generating a pecuniary scale diseconomy that largely offset the cost advantages that technological scale economies offered large plants. The larger plants' wage premium disappeared in the 1980's, and technological change created larger and more extensive technological scale economies. As a result, large plants realized growing cost advantages over smaller plants, and... |

| In an era of rapid consolidation in banking, the effect of mergers on the availability of credit to agricultural businesses is unclear. Commercial bank mergers have profoundly altered the urban credit marketplace and are positioned to do the same for the agricultural credit marketplace. Adjustment models are estimated with data on independent bank consolidations from 1988 through 1995. The regression results bode well for agricultural lending if acquiring banks have larger concentrations of assets in agriculture than acquired banks. Conversely, if acquiring banks have smaller concentrations than acquired banks, acquisitions have a negative impact on agricultural lending. Since most acquiring banks have smaller agricultural loan concentrations than... |
