A gripping tale of exploration aboard H.M.S. Challenger, an expedition that laid the foundations for modern oceanography From late 1872 to 1876, H.M.S. Challenger explored the world's oceans. ...Conducting deep sea soundings, dredging the ocean floor, recording temperatures, observing weather, and collecting biological samples, the expedition laid the foundations for modern oceanography. Following the ship's naturalists and their discoveries, earth scientist Doug Macdougall engagingly tells a story of Victorian-era adventure and ties these early explorations to the growth of modern scientific fields. In this lively story of discovery, hardship, and humor, Macdougall examines the work of the expedition's scientists, especially the naturalist Henry Moseley, who rigorously categorized the flora and fauna of the islands the ship visited, and the legacy of John Murray, considered the father of modern oceanography. Macdougall explores not just the expedition itself but also the iconic place that H.M.S. Challenger has achieved in the annals of ocean exploration and science.
Les poèmes de 1872 de Rimbaud se caractérisent par une opacification du rapport entre le texte et le monde. La 'réalité' y est mise à distance, la représentation mise à mal. Cet effacement relatif du ...référent n'implique cependant pas que tout 'réel' quel qu'il soit ait irrémédiablement déserté ces poèmes. Cet article se propose d'étudier ce qui, dans ces textes, demeure d'un lien physique au 'monde'. Le paradigme de la consommation s'avère central au sens où le sujet rimbaldien, pris d'une sorte de fringale de réel, perçoit moins le monde qu'il ne le dévore, l'avale. Cette poésie primitiviste élit pour objet des éclats de l'être, d'infimes morceaux de matière, dans une sorte d'arte povera. La présence 'au monde' y devient le principe d'une utopie, utopie tensionnelle au sens où coexistent en elle la possibilité et l'impossibilité d'une nouvelle communauté avec le monde.
Rimbaud's 1872 poems tend to render opaque the text's relationship to the world. 'Reality' is kept at a distance, and representation is put to the test. This blurring of the referent does not however mean that 'the real' has altogether vanished from these poems. This article looks at what remains, in them, of a physical link with the 'world', especially through the paradigm of consumption. The world is not only perceived, but devoured and swallowed by the Rimbaldian subject, in a form of craving for the real. This primitivist poetry elects as its objects fragments of being, tiny pieces of matter, as in an 'arte povera' of sorts. The self's presence to the world becomes the basis of a utopia that is constantly in tension, insofar as the possibility and impossibility of a new community with the world coexist in it.

The knowledge of the crustal strain rate tensor provides a description of geodynamic processes such as fault strain accumulation, which is an important parameter for seismic hazard assessment, as ...well as anthropogenic deformation. In the past two decades, the number of observations and the accuracy of satellite based geodetic measurements like GPS greatly increased, providing measured values of displacements and velocities of points. Here we present a method to obtain the full continuous strain rate tensor from dense GPS networks. The tensorial analysis provides different aspects of deformation, such as the maximum shear strain rate, including its direction, and the dilatation strain rate. These parameters are suitable to characterize the mechanism of the current deformation. Using the velocity fields provided by SCEC and UNAVCO, we were able to localize major active faults in Southern California and to characterize them in terms of faulting mechanism. We also show that the large seismic events that occurred recently in the study region highly contaminate the measured velocity field that appears to be strongly affected by transient postseismic deformation. Finally, we applied this method to coseismic displacement data of two earthquakes in Iceland, showing that the strain fields derived by these data provide important information on the location and the focal mechanism of the ruptures.
There are many challenges associated with enforcing the protections afforded Traditional Cultural Properties (TCPs) under the National Historic Preservation Act (NHPA). This paper examines how the ...rules and procedures that animate the law can create a striking disconnect between what the law appears to provide and what it actually delivers. After providing some brief background regarding the literature of legal geography and the protections offered to TCPs, this paper outlines some basic information regarding how administrative law polices both the entry to and operation of the formal legal space known as the federal judicial system through various jurisdictional requirements. It also addresses how mitigation requirements under Section 106 of the NHPA have been undermined as a result of legal processes and interpretive case law. As a relevant example, it uses the current controversy over proposed uranium mining on New Mexico's Mount Taylor. Deemed eligible for federal designation as a TCP in 2008, Mt. Taylor provides a case study in the challenges associated with protecting sacred lands within the processes and frameworks of the current legal system. While the NHPA gives the appearance of honoring Indigenous ontologies, its materialization often results in little more than bureaucratic procedures giving only the appearance of adequate treatment by limiting judicial enforcement.
