Sommario/riassunto |
|
As a presidential candidate, Barack Obama criticized the George W. Bush administration for its unrestrained actions in matters of national security. In secret Justice Department memos, President Bush's officials had claimed for the executive branch total authority to use military force in response to threats of terrorism. They set aside laws made by Congress, even criminal laws prohibiting torture and warrantless surveillance. Candidate Obama promised to restore the rule of law and make a clean break with the Bush approach. President Obama has not done so. Why? In a thorough comparison of the Bush and Obama administrations' national security policies, Chris Edelson demonstrates that President Obama and his officials have used softer rhetoric and toned-down legal arguments, but in key areas-military action, surveillance, and state secrets-they have simply found new ways to assert power without meaningful constitutional or statutory constraints. Edelson contends that this legacy of the two immediately post-9/11 presidencies raises crucial questions for future presidents, Congress, the courts, and American citizens. Where is the political will to restore a balance of powers among branches of government and adherence to |

the rule of law? What are the limits of authority regarding presidential national security power? Have national security concerns created a permanent shift to unconstrained presidential power? |

Sommario/riassunto |

"Comprehensive and readable, this book provides the tools and techniques to properly analyze the effects of high temperature on reinforced concrete, leading to safer, more stable structures. Based on years of the author's research, Reinforced Concrete at Elevated Temperatures' four part treatment starts with an unambiguous and thorough exposition of the mechanical behaviours of materials at elevated temperature, followed by a discussion of temperature field of |

member sections, mechanical behaviours of members and structures at elevated temperature, and theoretical analysis and practical calculation methods. The book provides unique insight into: - Coupling thermal-mechanical constitutive relation of concrete - Exceptional analyses of beams and columns of rectangular section with three surfaces and two adjacent surfaces exposing to high temperature - Measurement and analysis of redistribution of internal forces of statically indeterminate structure during heating-loading process - Finite element analysis and calculation charts for two-dimensional temperature field of structural members With this book, engineers and architects can effectively analyze the result of high temperature on concrete and materials which will lead to better designs of fire resistant structures, as well as damage evaluation and treatment after fire"-- |
