The material recovery methods used by dust-yards in early 19 th century London, England and the conditions that led to their development, success and decline are reported. The overall system developed in response to the market value of constituents of municipal waste, and particularly the high coal ash content of household 'dust.' The emergence of lucrative markets for 'soil' and 'breeze' produ...

The question of whether ocean iron fertilization (OIF) can yield verifiable carbon sequestration is often cast in terms of whether fertilization results in enhanced particle export. However, model studies show that oceanic carbon storage is only weakly related to global particle export — depending instead on an increase in the carbon associated with the pool of remineralized nutrients. The magn...

Using the data obtained from the structured interviews of 33 professionals with a high level of technical knowledge specific to the subject of intermodal rail yards and their associated operations, this study addresses 10 issues that cover not only the design and layout issues within a terminal, but also broader topics such as administration/ownership, location, and other topics that may be ove...

In order to become a mega hub port, major ports all over the world are making every effort to enhance their productivity through efficiency of internal operation. Accordingly, in order to enhance the competitiveness of a container terminal, an automated container terminal is considered as the best alternative. An automated container terminal is using such automated handling equipment as AGV (Au...

Waste water containing high levels of NaCl from cucumber fermentation tank yards is a continuing problem for the pickled vegetable industry. A major reduction in waste salt could be achieved if NaCl were eliminated from the cucumber fermentation process. The objectives of this project were to ferment cucumbers in brine containing CaCl(2) as the only salt, to determine the course of fermentation...

The current financial crisis seems to be seriously affecting the freight transport system. In this scenario, transport terminals play a crucial role to avert the risk of recession by increasing their efficiency and automation. Only in this way is it possible both to reduce the price of the services offered (loading, unloading, dwelling, logistic services ...) and increase terminal earnings. In ...

Parameters, such as oil, protein, glucosinolates, chlorophyll content and fatty acid composition, were determined using reference methods for both harvest survey samples and Canadian Canola exports. Canola harvest survey and export data were assessed to evaluate if canola harvest survey data can be extrapolated to predict the quality of the Canadian canola exports. There were some differences i...

The results of several recent investigations indicate that length of day or photoperiod is an important factor in determining the length of growing season in certain species of woody plants. The short days of late summer and autumn stop stem elongation and the production of new leaves in a number of species long before temperatures are low enough to check growth. This has been strikingly demons...
