Improving the structural reliability of steel frames using posttensioned connections [PDF]
In this paper, various moment-resisting steel frames (MRSFs) are subjected to 30 narrow-band motions scaled at different ground motion intensity levels in terms of spectral acceleration at first mode of vibration in order to perform incremental dynamic ...

Challenges and Experiences of Managed Aquifer Recharge in the Mexico City Metropolitan Area. [PDF]
Abstract The Mexico City Metropolitan Area (MCMA) is a significant and important urban center in North America, covering an area of approximately 9500 km2 with a population of almost 23 million, yet the water supply remains unsustainable. The total water demand in the MCMA is 84 m3/s and is provided by groundwater (63% or 53 m3/s), imported water (27 ...

The Unflinching Mr. Smith and the Nuclear Age*. [PDF]
Abstract This article focuses on the U.S. diplomat and nuclear arms control negotiator Gerald (Gerry) Coat Smith in order to cast new light on the importance of diplomats in the context of the set of international activities currently labelled as “science diplomacy.” Smith, a lawyer by training, was a key negotiator in many international agreements on ...

Estimation of cyclic interstory drift capacity of steel framed structures and future applications for seismic design. [PDF]
Several studies have been devoted to calibrate damage indices for steel and reinforced concrete members with the purpose of overcoming some of the shortcomings of the parameters currently used during seismic design. Nevertheless, there is a challenge to study and calibrate the use of such indices for the practical structural evaluation of complex ...

Abstract A long‐standing aim of cinema – in particular of ‘extreme’, ‘unwatchable’ or ‘feel‐ bad’ cinema – has been to acquaint viewers with extreme suffering. In this article I first offer an explication of that aim in terms of recent work in philosophy of mind, then exploit the resulting framework to examine claims to the effect that a new ...

Long‐term processes between Classic and Postclassic populations in the Mexico basin
Abstract The study of nonmetric traits is useful for establishing biological differences or affinities between populations. This study considered 12 nonmetric cranial characters. The objective is to compare five series of two different cultural horizons: three populations of the Teotihuacán Classic period and two of the Mexica Postclassic period.

Foul Biting, or Diego Valadés and the Medium of Print
Published in 1579 in Perugia, Diego Valadés's Rhetorica christiana is best known today as the first illustrated publication to show evangelisation efforts in the Americas to audiences across the Atlantic. Yet too often the Rhetorica's status in the history of art is that of exotica, a book seen as rare and valuable due to its American subject matter ...

Human activities can be noisy, especially in urban areas, and affect animals detrimentally. Traffic noise may interfere with acoustic communication through masking and may yield noise‐dependent modification of acoustic signals. Such vocal flexibility in birds has been investigated most often for songs, but rarely for calls, even though calls are ...

The control of vibrations and damage in traditional reinforced concrete (RC) buildings under earthquakes is a difficult task. It requires the use of innovative devices to enhance the seismic behavior of concrete buildings. In this paper, we design RC buildings with buckling restrained braces (BRBs) to achieve this objective.
