Why do drug traffickers fight states? In Mexico, Colombia and Rio de Janeiro, Brazil, cartel state conflict has been just as lethal, disruptive, and prolonged as civil war. Yet rebel insurgents fight for and sometimes win formal concessions or outright victory. Why fight the state if, like cartels, you seek neither to topple nor secede from it? More puzzling, recent militarized state crackdowns...

• National heritage status important driver for improved fire protection. 25% safety plan coverage in 2014, increased to 60% 2020. Stamina, i.e. systematic work over 10+ years, an success criterion. Automatic smoke alarms and IR cameras very early response. Knowledge sharing between involved parties should be strengthened. There is a genuine will protect Nordic wooden towns Norway, as they are ...

This paper presents a simplified approximate analysis of the overall collapse of the towers of World Trade Center in New York on September 11, 2001. The analysis shows that if prolonged heating caused the majority of columns of a single floor to lose their load carrying capacity, the whole tower was doomed.

A small number of fires escape initial attack suppression efforts and become large, but their effects are significant and disproportionate. In 1983, of 200,000 wildland fires in the United States, only 4,000 exceeded 100 acres. However, these escaped fires accounted for roughly 95 percent of wildfire-related costs and damages (Pyne, 1984). Thus, future research efforts logically will focus on t...

The present study was intend to track down the transitional process in which the hierarchical dominance in the urban structure of Namwon City shifted from the Namwoneupseong Walled Town to the area of Gwanghalluwon Garden by using cadastral data and various historical sources. It was aimed to find the factors regarding the transition and a sustainable development plan to the historical landscap...

reports that have appeared in Science (3, 4), these results merit further investigation. Bemer and Landis indicate that during the Late Cretaceous [75 to 95 million years ago (Ma)] the 02 content of the atmosphere was "greater than 30 percent," whereas in the Eocene-Oligocene values were 21%, as today. Lovelock (2) asserts that "at 25% oxygen even damp twigs and grass of a rainforest would igni...

Extreme global warmth and an abrupt negative carbon isotope excursion during the Paleocene–Eocene Thermal Maximum (PETM) have been attributed to a massive release of methane hydrate from sediments on the continental slope [G.R. Dickens, J.R. O'Neil, D.K. Rea, R.M. Owen, Dissociation of oceanic methane hydrate as a cause of the carbon isotope excursion at the end of the Paleocene, Paleoceanograp...

On the afternoon of 18 January 2003, a number of separate fires located to the west of Canberra, Australia, began major runs under extreme fire weather conditions, and impacted upon the city. These events were well documented by a range of instruments, including a multispectral line-scanning instrument attached to an aircraft. Analysis of the data collected revealed that a number of the fires h...

This paper provides the first comprehensive description of the Z1, the mechanical computer built by the German inventor Konrad Zuse in Berlin from 1936 to 1938. The paper describes the main structural elements of the machine, the high-level architecture, and the dataflow between components. The computer could perform the four basic arithmetic operations using floating-point numbers. Instruction...
