a Supertanker against bureaucracy in the wake of a housing crisis neoliberalizing planning in netanyahu s israel
Antipode, 2017Co-Authors: Igal CharneyAbstract:This paper critically questions the state's hostile takeover of planning regulation followed by experimentation initiated by the Israeli Prime Minister Benjamin Netanyahu who has been seeking to subordinate the planning apparatus to market calculus and to short-term political ends. To substantiate this argument, I have examined a large corpus of documents (official government documents, planning records, and court appeals and rulings, and NGO reports) and analyzed the media coverage between 2011 and 2016. By introducing fast-track planning that is firmly controlled by the central state and focusing on the fictitious delivery of housing units, the structure of the planning regulation has dramatically changed. Further, two already-dominant government ministries (Finance and Defense) have been significantly empowered, becoming the supervisors of the reformed planning system. In a state captivated by neoliberal fixation and embroiled in a housing crisis, the restructuring of planning governance has been a means to an end.

turning the carbon Supertanker sectoral feasibility of climate change mitigation in china
Energy research and social science, 2018Co-Authors: Joshua W Busby, Xue Gao, Sarang ShidoreAbstract:Abstract Whether China can slow the growth of emissions of greenhouse gases and ultimately reduce them has become a central question for climate mitigation. In previous research on India, we developed a theoretical framework to assess the structural characteristics of different sectors and identify which ones were most amenable to mitigation. In this article, we extend that approach to China and review the nine sectors responsible for most of the country's emissions. These include electricity (disaggregating renewables, nuclear, and coal), road transportation, four disaggregated industry sub-sectors (steel, cement, fertilizers, and oil refining), and buildings. We identify two sets of attributes, what we called political/organizational feasibility and techno-economic feasibility, that together shape the possibilities for emissions mitigation. Our central intuition is that fragmentation − on the government or market side or both − makes collective action more difficult. Cement, steel, and oil refining possess favorable characteristics on both political/organizational feasibility and techno-economic feasibility, while fertilizers and renewables pose the most difficult challenges on both dimensions. Buildings and road transport are mixed cases, where techno-economic feasibility is high while political/organizational dynamics are more challenging. Finally, coal and nuclear are mixed cases where political/organizational feasibility is high but techno-economic aspects are more challenging.

geochemical changes in crude oil spilled from the exxon valdez Supertanker into prince william sound alaska
Organic Geochemistry, 1994Co-Authors: Frances D Hostettler, Keith A KvenvoldenAbstract:Abstract North Slope crude oil spilled from the T/V Exxon Valdez in March 1989 and contaminated about 500 km of Prince William Sound shoreline. Aliphatic and aromatic hydrocarbons in oil samples collected in August 1990 and June 1992 from beaches on six islands impacted by the spill have been compared with the hydrocarbons from North Slope crude oil taken from the stricken tanker. Degradation processes have changed the physical appearance of this residual spilled oil; the beached oil as collected ranged from a light brown color, to a heavy black viscous oil, to a black, powder-like residue. In these physically different samples, terpane, sterane, and aromatic sterane distributions, as well as carbon isotope values, are similar and correlate with the original Exxon Valdez oil. On the other hand, n -alkanes, isoprenoids, and many of the polycyclic aromatic hydrocarbons which are present in the original crude oil are dramatically altered in the oil samples collected from the beaches.

space shuttle with common fuel tank for liquid rocket booster and main engines Supertanker space shuttle
NASA Washington Space Transporation Propulsion Technology Symposium. Volume 3: Panel Session Summaries and Presentations, 1991Co-Authors: Douglas G ThorpeAbstract:An operation and schedule enhancement is shown that replaces the four-body cluster (Space Shuttle Orbiter (SSO), external tank, and two solid rocket boosters) with a simpler two-body cluster (SSO and liquid rocket booster/external tank). At staging velocity, the booster unit (liquid-fueled booster engines and vehicle support structure) is jettisoned while the remaining SSO and supertank continues on to orbit. The simpler two-bodied cluster reduces the processing and stack time until SSO mate from 57 days (for the solid rocket booster) to 20 days (for the liquid rocket booster). The areas in which liquid booster systems are superior to solid rocket boosters are discussed. Alternative and future generation vehicles are reviewed to reveal greater performance and operations enhancements with more modifications to the current methods of propulsion design philosophy, e.g., combined cycle engines, and concentric propellant tanks.
