Evolution from a hinge actuator mechanism to an antenna deployment mechanism for use on the European large communications satellite (L-SAT/OLYMPUS)

The evolution of an Antenna Deployment Mechanism (ADM) from a Hinge Actuator Mechanism (HAM) is described as it pertains to the deployment of large satellite antennas. Design analysis and mechanical tests are examined in detail

Death Bed

Lethal injection is this country\u27s primary method of execution, adopted for use by all but one of the thirty-seven death penalty states, as well as the federal government. It is predictable, then, that questions would arise the moment such a widely accepted form of punishment becomes especially vulnerable to an Eighth Amendment attack, as recent cases have shown. This article discusses this author\u27s involvement as an expert in one of these cases, Baze v. Rees, which concerned a 2005 challenge to the constitutionality of lethal injection in Kentucky. While the Baze court upheld the constitutionality of Kentucky\u27s lethal injection procedure, the opinion also revealed some extraordinary and unprecedented statements about the flaws of lethal injection as well as recommendations for how it should be improved. For example, the court found it cruel and unusual for the state\u27s lethal injection protocol to enable an inmate\u27s neck to be catheterized, a decision influenced by a department of corrections doctor who testified he would refuse to conduct the procedure, and that those who would were unqualified to do so. Baze is one of a series of opinions demonstrating that the more we know about how lethal injection is administered, the more problems we find with this means of execution

Interrogating Michel Foucault’s counter-conduct: theorising the subjects and practices of resistance in global politics

Resistance, and its study, is on the rise: visible and politically discernible practices of dissent against sovereignty ad economic exploitation, such as protesting, agitating and occupying have received increased analytical attention in the past decade. This special issue provides much needed systematic attention to less visible practices of resistance or those not manifested in expressly political registers. It focuses on attempts to inventively modify, resist or escape the ways in which we are governed by interrogating critically the politics and ethics of resistance to ‘power that conducts’, expressed through Foucault’s notion of ‘counter- conduct.’ The contributions first, theoretically interrogate, develop, and refine the concept of ‘counter-conduct(s)’, offering a major statement its importance for both the study of resistance and also its place in Foucault’s work. Second, they provide inter/multi-disciplinary empirical investigations of counter-conduct in numerous thematic areas and spaces of global politics. Third, they explicitly reflect on variable and contingent forms of counter-conduct, examining its close relationship with conducting power. Finally, the special issue concertedly considers issues of methodology and method emerging from the study of counter-conduct and how these also recalibrate the study of governing power itself

Controls on the spatial distribution of oceanic <i>δ</i>¹³C_DIC

We describe the design and evaluation of a large ensemble of coupled climate–carbon cycle simulations with the Earth system model of intermediate complexity GENIE. This ensemble has been designed for application to a range of carbon cycle questions, including the causes of late- Quaternary fluctuations in atmospheric CO2. Here we evaluate the ensemble by applying it to a transient experiment over the recent industrial era (1858 to 2008 AD). We employ singular vector decomposition and principal component emulation to investigate the spatial modes of ensemble variability of oceanic dissolved inorganic carbon (DIC) δ13C, considering both the spun-up pre-industrial state and the transient change. These analyses allow us to separate the natural (preindustrial) and anthropogenic controls on the δ13CDIC distribution. We apply the same dimensionally reduced emulation techniques to consider the drivers of the spatial uncertainty in anthropogenic DIC. We show that the sources of uncertainty related to the uptake of anthropogenic δ13CDIC and DIC are quite distinct. Uncertainty in anthropogenic δ13C uptake is controlled by air–sea gas exchange, which explains 63% of modelled variance. This mode of variability is largely absent from the ensemble variability in CO2 uptake, which is rather driven by uncertainties in thermocline ventilation rates. Although the need to account for air–sea gas exchange is well known, these results suggest that, to leading order, uncertainties in the ocean uptake of anthropogenic 13C and CO2 are governed by very different processes. This illustrates the difficulties in reconstructing one from the other, and furthermore highlights the need for careful targeting of both δ13CDIC and DIC observations to better constrain the ocean sink of anthropogenic CO2
