Sommario/riassunto |
|
"As aquaculture continues to grow at a rapid pace, understanding the engineering behind aquatic production facilities is of increasing importance for all those working in the industry. Aquaculture engineering requires knowledge of the many general aspects of engineering such as material technology, building design and construction, mechanical engineering, and environmental engineering. In comprehensive book now in its second edition, author Odd-Ivar Lekang introduces these principles and demonstrates how such technical knowledge can be applied to aquaculture systems"-- |

Sommario/riassunto |
|
We employ an extended version of the Allen et al. (2002) Balance Sheet Approach to examine macroeconomic vulnerabilities in Colombia |
|
|
|
|
|
|
|
|
|
|
between 1996 and 2003, based on an unusually rich data set. We find that vulnerabilities existing prior to Colombia's 1999 recession-high levels of private debt, a large negative foreign currency position of the corporate sector, and banks' exposure to stretched households and companies-receded subsequently. New vulnerabilities emerged, however, especially the high level of public debt accumulated until end-2003, and growing exposure of the financial sector to the sovereign. |
