Burdened by Proof: How the Australian Refugee Review Tribunal has failed lesbian and gay asylum seekers

Our argument in this paper is that the evidentiary practices and procedures that have been developed by the Australian Refugee Review Tribunal are operating at a routinely low standard. Such practices contribute to decisions that are manifestly unfair and potentially wrong in law. Our conclusions are drawn from our detailed study of more than 300 refugee tribunal decisions made in Canada and Australia in response to asylum claims brought by lesbians and gay men

Forced Marriage as a Harm in Domestic and International Law

This article reports on our analysis of 120 refugee cases from Australia, Canada, and Britain where an actual or threatened forced marriage was part of the claim for protection. We found that forced marriage was rarely considered by refugee decision makers to be a harm in and of itself. This finding contributes to understanding how gender and sexuality are analysed within refugee law, because the harm of forced marriage is experienced differently by lesbians, gay men and heterosexual women. We contrast our findings in the refugee case law with domestic initiatives in Europe aimed at protecting nationals from forced marriages both within Europe and elsewhere. We pay particular attention to British initiatives because they are in many ways the most far-reaching and innovative, and thus the contrast with the response of British refugee law is all the more stark

Backstreaming of Impurity Gas Through a Leak in Pressurized Vessel

The presence of a leak in a vessel containing pure gas can induce the contamination by atmospheric gas diffusing into the vessel. In order to avoid this, a gas which has to be kept pure also in presen ce of a leak is usually pressurized, to reduce the flow of contaminating gas through the leak owing to the molecular drag by the outstreaming pure gas. In this paper, a simple model calculation of ba ckstreaming based on the solution of the diffusion + drag equation in cylindrical coordinates is presented. It is shown that both the pressure difference and the dimension of the leak are critical in determining the contaminating flow, a maximum in the backstreaming flow appearing when the drag velocity of the outstreaming gas equals the diffusion velocity

Governing Global Supply Chain Sustainability Through the Ethical Audit Regime

Over the past two decades multinational corporations have been expanding ‘ethical’ audit programs with the stated aim of reducing the risk of sourcing from suppliers with poor practices. A wave of government regulation—such as the California Transparency in Supply Chains Act (2012) and the UK Modern Slavery Act (2015)—has enhanced the legitimacy of auditing as a tool to govern labor and environmental standards in global supply chains, backed by a broad range of civil society actors championing audits as a way of promoting corporate accountability. The growing adoption of auditing as a governance tool is a puzzling trend, given two decades of evidence that audit programs generally fail to detect or correct labor and environmental problems in global supply chains. Drawing on original field research, this article shows that in spite of its growing legitimacy and traction among government and civil society actors, the audit regime continues to respond to and protect industry commercial interests. Conceptually, the article challenges prevailing characterizations of the audit regime as a technical, neutral, and benign tool of supply chain governance, and highlights its embeddedness in struggles over the legitimacy and effectiveness of the industry-led privatization of global governance

Swift Highly Charged Ion Channelling

We review recent experimental and theoretical progress made in the scope of swift highly charged ion channelling in crystals. The usefulness of such studies is their ability to yield impact parameter information on charge transfer processes, and also on some time related problems. We discuss the cooling and heating phenomena at MeV/u energies, results obtained with decelerated H-like ion beams at GSI and with ions having an excess of electrons at GANIL, the superdensity effect along atomic strings and Resonant Coherent Excitation.Comment: to be published in Journal of Physics

Technical Analysis and Statistics from Long Term Helium Cryoplant Operation with Experimental Superconducting Magnets at CERN

CERN regularly uses a large number of liquid helium cryoplants for cooling the superconducting magnets of large particle detectors. They are installed in the experimental areas of the electron-positron collider LEP and the proton (and heavy ion) accelerator SPS for the observation of high-energy interactions of elementary particles. The typical cold mass of a detector magnet ranges from 1 to 40 tons, and typical cryoplant cooling capacities are between 400 and 800 W/4.5 K entropy equivalent. Operation must be very flexible to meet the varying experimental requirements. We intend to present technical data of the system and statistics from over 180'000 running hours during the four years from 1992 to 1995. Operation includes phases of cool-down, steady-state cooling, recovery after magnet quench or other incidents and warm-up of the superconducting magnets. Emphasis will be laid on the analysis of fault conditions, multiple interaction between perturbations and consequences for the users of liquid helium supply interruption

Conclusions from 12 Years Operational Experience of the Cryoplants for the Superconducting Magnets of the LEP Experiments

The Large Electron Positron Collider (LEP) has ended its last physics run in November 2000, and it is at present being dismantled to liberate the tunnel for the Large Hadron Collider (LHC) project to be completed by end of 2005. The cryogenic systems for the superconducting solenoid and focusing quadrupoles for the two LEP experiments, ALEPH and DELPHI, each supplying a cooling power of 800 W/4.5 K entropy equivalent, have accumulated more then 100'000 hours of running time. The paper summarises the 12 years cryogenic experience in the various operating modes: cool-down, steady state, recovery after energy fast dump, utilities failures and warm-up of the superconducting magnets. The detailed operation statistics is presented and compared to the other CERN cryogenic systems. Emphasis is given to the technical analysis of the fault conditions and of their consequences on the helium refrigeration production time in view of the future operation of the LHC cryogenics

The cryogenic system for the superconducting solenoid magnet of the CMS experiment

The design concept of the CMS experiment, foreseen for the Large Hadron Collider (LHC) project at CERN, is based on a superconducting solenoid magnet. The large coil will be made of a four layers winding generating the 4 T uniform magnetic induction required by the detector. The length of the solenoid is 13 m with an inner diameter of 5.9 m. The mass kept at liquid helium temperature totals 220 t and the electromagnetic stored energy is 2.7 GJ. The windings are indirectly cooled with a liquid helium flow driven by a thermosyphon effect. The external cryogenic system consists of a 1.5 kW at 4.5 K (entropy equivalent) cryoplant including an additional liquid nitrogen precooling unit and a 5000 litre liquid helium buffer. The whole magnet and cryogenic system will be tested at the surface by 2003 before final installation in the underground area of LHC

New Long-term Historical Data Recording and Failure Analysis System for the CERN Cryoplants

CERN uses several liquid helium cryoplants (total of 21) for cooling large variety of superconducting devices namely: accelerating cavities, magnets for accelerators and particle detectors. The cryoplants are remotely operated from several control rooms using industrial standard supervision systems, which allows the instant display of all plant data and the trends, over several days, for the most important signals. The monitoring of the cryoplant performance during transient conditions and normal operation over several months asks for a long-term recording of all plant parameters. An historical data recording system has been developed, which collects data from all cryoplants, stores them in a centralized database over a period of one year and allows an user-friendly graphical visualization. In particular, a novel tool was developed for debugging causes of plant failures by comparing selected reference data with the simultaneous evolution of all plant data. The paper describes the new system, already in operation with 11 cryoplants
