The UN blames the fact that the quake hit a densely populated capital city, knocking out many of the agencies that would have dealt with disaster relief. Geologists speaking to New Scientist explained some of the other reasons why the quake was so bad, and warned that more quakes may come, because not all the pent-up seismic energy was released in the tragedy. First, the quake was "shallow source" and so allowed less warning time to get out of buildings than deep quakes. And Port au Prince is built not on solid rock but on soil, which collapses when shaken. Finally, building standards were not adequate for major earthquakes. If a similar quake occurred in California, the death toll would almost certainly have been much lower. "Better buildings would have saved lives," says Chuck DeMets, a tectonic geologist from the University of Wisconsin-Madison. Tale of two quakes A comparison with two very similar earthquakes backs up this assertion. Both occurred in densely populated regions, but they had very different outcomes. In 1988, the Spitak magnitude-6.9 earthquake in Armenia took more than 25,000 lives. By contrast the magnitude-7.1 Loma Prieta earthquake in 3 Infoteca’s E-Journal No.99 January 2010 Sistema de Infotecas Centrales Universidad Autónoma de Coahuila California in 1989 caused only 63 deaths. "The difference in the numbers of fatalities illustrates the huge effect that high building standards can have in saving people's lives," says DeMets. The multi-storey concrete buildings that made up much of Port-au-Prince proved to be death traps when the earthquake struck. "The buildings were brittle and had no flexibility, breaking catastrophically when the earthquake struck," says Ian Main, a seismologist at the University of Edinburgh, UK. And the disaster was compounded by the earthquake's shallow source. "With deep earthquakes the primary waves arrive first, giving you a bit of warning before the shear waves [responsible for shaking the ground from side to side] arrive," says Uri ten Brink, an expert on earthquakes in the Caribbean from the US Geological Survey in Woods Hole, Massachusetts. In Haiti the epicentre was so close to the surface that the primary and shear waves arrived almost at the same time. Design and survive So what kind of buildings can withstand this kind of shake? "Engineers use more flexible materials with a built-in capacity to absorb damage, much as car bonnets are now designed to crumple, leaving the interior intact," explains Main. "This might include base-isolation shock absorbers on the first floor, to help resist or minimise dynamic shear and twisting motions." Retrofitting conventional buildings to make them earthquake-proof is expensive, but constructing new buildings to be shake-proof is not. "Seismic-resistant buildings cost a few per cent more in building materials and need a little extra designer time, but they are not a great deal more expensive than ordinary buildings," says Main. http://www.newscientist.com/article/dn18406-why-the-haiti-quake-killed-so- many.html?DCMP=NLC-nletter&nsref=dn18406 4 Infoteca’s E-Journal No.99 January 2010 Sistema de Infotecas Centrales Universidad Autónoma de Coahuila Alive and Well December 28, 2009 By Mary B. Marcy The liberal arts are higher education’s answer to Broadway, that "fabulous invalid" whose demise is predicted with both certainty and regularity. Claims that the liberal arts are in jeopardy have taken on increased urgency in the current economic climate. As students swell the ranks of community colleges, the presumption is that readily identifiable and employable skills rather than broad and deep learning are the primary focus of their educational ambitions. But in the case of the liberal arts, conventional wisdom is at odds with what experience and current data suggest. For example, the benchmark freshmen surveys conducted each year by UCLA’s Higher Education Research Institute show an increasing appetite for the kind of educational experience typically associated with the liberal arts. In 2008, for the first time since 1982, more than 50 percent of first year students identified “developing a meaningful philosophy of life” as an important or very important goal of their college experience. Similarly, the venerable pollster John Zogby has found that a growing segment -- including but not limited to the traditional college age population -- of United States citizens believes living a "meaningful life" is central to the realization of the American dream. And despite dire predictions, enrollment at most liberal arts colleges, including my own, has risen during this difficult economic year. There are likely two reasons for this gap between conventional wisdom and student decision making.

The magnitude of the mass deficit is in principle related to the galaxy’s merger history, but the relation has never been quantified. Here, high- accuracy N-body simulations are used to calibrate this relation. Mass deficits are shown to be Mde f ≈ 0.5M12, with M12 the total mass of the binary; the coefficient in this relation depends only weakly on M2/M1 or on the galaxy’s pre-existing density profile. Hence, after N mergers, Mde f ≈ 0.5N M• with M• the final (current) black hole mass. When compared with observed mass deficits, this result implies 1 ∼< N ∼< 3, in accord with hierarchical galaxy formation models.

    SPECULATION ON ARCHITECTURE IN THE ABSENCE OF GRAVITY Speculation on Architecture in the absence of Gravity. How might architectural elements and design strategies function in outer space? Hermann Matamu 132 8392 Master Thesis explanatory document: Jeanette Budgett Abstract The evolution of architecture has been driven by a combination of elements such as style, context, materiality, aesthetic and technology. The development of materials and the technological advancements of the human race are conveyed through architecture; from the technical expertise of the ancient Egyptians in pyramid construction, to the engineering feats of the Eiffel Tower in Paris, to the physical realisation of Gehry’s Guggenheim through computer modelling. Architecture is a continuous evolution which revolves around the progression of the human race in all fields of life. Space habitation presents the next step in this architectural evolution, in which Space tourism acts as the stepping stone for the transition of architectural design beyond Earth. Space design has been produced largely without architectural input. The aim of this project is to introduce an architectural sensibility, and to investigate the impact an absence of gravitational force has on architecture. The research follows the transition of architectural design from an environment of gravity to one without, by reviewing both current literature and precedent case studies. i Acknowledgements As this chapter in my life comes to an end, I would like to thank all those who made it a memorable one. Firstly, I would like to thank my supervisor, Jeanette Budgett. Thank you for your patience, support and constant encouragement throughout my research, your knowledge and time have been instrumental in the development of this project.

To introduce such a dark energy contaminated black hole's gravitational force, a new pseudo-Newtonian potential is used. This pseudo-Newtonian force can be calculated if we know the distance from the black hole's center, spin of the black hole and equation of state of the quintessence inside which the black hole is considered to lie. This force helps us to avoid complicated nonlinearity of general relativistic field equations. Transonic, viscous, continuous and Keplerian flow is assumed to take place. Fluid speed, sonic speed profile and specific angular momentum to Keplerian angular momentum ratio are found out for different values of spin parameter and arXiv:1911.08304v2 [gr-qc] 2 Mar 2021 quintessence parameter.

  • Extracting the Gravitational Recoil from Black Hole Merger Signals
    Extracting the Gravitational Recoil from Black Hole Merger Signals Vijay Varma,1, ∗ Maximiliano Isi,2, † and Sylvia Biscoveanu2, ‡ 1TAPIR 350-17, California Institute of Technology, 1200 E California Boulevard, Pasadena, CA 91125, USA 2LIGO Laboratory, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA (Dated: March 11, 2020) Gravitational waves carry energy, angular momentum, and linear momentum. In generic binary black hole mergers, the loss of linear momentum imparts a recoil velocity, or a “kick”, to the remnant black hole. We exploit recent advances in gravitational waveform and remnant black hole modeling to extract information about the kick from the gravitational wave signal. Kick measurements such as these are astrophysically valuable, enabling independent constraints on the rate of second-generation mergers. Further, we show that kicks must be factored into future ringdown tests of general relativity with third-generation gravitational wave detectors to avoid systematic biases. We find that, although little information can be gained about the kick for existing gravitational wave events, interesting measurements will soon become possible as detectors improve. We show that, once LIGO and Virgo reach their design sensitivities, we will reliably extract the kick velocity for generically precessing binaries—including the so-called superkicks, reaching up to 5000 km/s.
