Oxygen isotopes and hydrocarbon composition of gas hydrate and hydrate water from ODP Leg 165 sites

Ocean Drilling Program (ODP) Leg 164 recovered a number of large solid gas hydrate from Sites 994, 996, and 997 on the Blake Ridge. Sites 994 and 997 samples, either nodular or thick massive pieces, were subjected to laboratory analysis and measurements to determine the structure, molecular and isotopic composition, thermal conductivity, and equilibrium dissociation conditions. X-ray computed tomography (CT) imagery, X-ray diffraction, nuclear magnetic resonance (NMR), and Raman spectroscopy have revealed that the gas hydrates recovered from the Blake Ridge are nearly 100% methane gas hydrate of Structure I, cubic with a lattice constant of a = 11.95 ± 0.05 angström, and a molar ratio of water to gas (hydration number) of 6.2. The d18O of water is 2.67 per mil to 3.51 per mil SMOW, which is 3.5-4.0 heavier than the ambient interstitial waters. The d13C and dD of methane are -66 per mil to -70 per mil and -201 per mil to -206 per mil, respectively, suggesting that the methane was generated through bacterial CO2 reduction. Thermal conductivity values of the Blake Ridge hydrates range from 0.3 to 0.5 W/(m K). Equilibrium dissociation experiments indicate that the three-phase equilibrium for the specimen is 3.27 MPa at 274.7 K. This is almost identical to that of synthetic pure methane hydrate in freshwater.

Energetic performance of landfill and digester biogas in a domestic cooker

The energetic performance of landfill biogas (LB) and biodigester biogas (BB) from municipal waste was examined in consumption tests. These tests were performed in situ at a gas generation plant associated with a landfill facility in Madrid (Spain) and following the standard UNE-EN 30-2-1 (1999). The jets of a domestic cooker commonly used for natural gas (NG) or liquefied petroleum gas (LPG) were modified to operate with the biogases produced at the facility. The working pressures best suited to the tested gases, i.e., to avoid flashback and flame lift, and to ensure the stability and correct functioning of the flame during combustion, were determined by trial and error. Both biogases returned optimum energetic performance for the transfer of heat to water in a metallic recipient (as required by the above standard) at a supply pressure of 10 mbar. Domestic cookers are normally supplied with NG at a pressure of 20 mbar, at which pressure the energetic performance of G20 reference gas was higher than that of both biogases (52.84% compared to 38.06% and 49.77% respectively). Data concerning these issues involving also unexplored feedstock are required for the correct conversions of domestic cookers in order to avoid risks of serious personal injuries or property damages.

Transmission and Transport of Energy in the Western U.S. and Canada: A Law and Policy Road Map

This collection of short essays arose from the inaugural meeting of the Idaho Symposium on Energy in the West, which was held in November, 2014. The topic for this first Symposium was Transmission and Transport of Energy in the Western U.S. and Canada: A Law and Policy Road Map. The essays in this collection provide a notable introduction to the major energy issues facing the West today. Topics include: building a resilient legal architecture for western energy production; natural gas flaring; transmission planning for wind energy; utilities and rooftop solar; special considerations for western states and the Clean Power Plan; the Clean Power Plan's implications for the western grid; siting renewable energy on public lands; and implications of utility reform in New York and Hawaii for the Northwest.

A Watershed Approach to Managing the Natural Resources in South Carolina

Environmental degradation from point and non-point source pollution in the past ten years has made it increasingly clear that threats to aquatic resources cannot adequately be addressed without a more integrated watershed approach to the management. Through comprehensive, qualitative interviews of experts in the watershed approach in South Carolina, recommendations will be made to improve this holistic process. Conducting interviews to compile institutional knowledge on the incentives and barriers from professionals working within the watershed approach will show how managing the natural resources in South Carolina could be more effective and efficient. By gathering experiences of lessons learned, best approach techniques, and suggestions for future watershed planning, several recommendations were made to further the use of the watershed approach in South Carolina.

The Europeanisation of Criminal Law and the Criminal Law Dimension of European Integration. Research Papers in Law, 3/2005

From the Introduction. In the academic year 1991-1992, Utrecht University, on my initiative, started to offer courses in European criminal law. This initiative came at a symbolic moment, just prior to the entry into force of the EU Treaty of Maastricht1 and the outlining of European policy in the areas of Justice and Home Affairs (JHA). The Director of the Legal Department, Paul DEMARET, was aware of the significance of this development and I have been given the opportunity to teach this subject at the College of Europe since 1995. Since then, JHA has evolved into one of the main areas of EU legislation. Now we are again on the threshold of an important historical feat. In June 2003, the European Convention reached agreement concerning a draft Treaty establishing a Constitution for Europe.2 The use of the term “Constitution” for the future EU Treaty is not simply cosmetic. The realisation has dawned that EU integration must be embedded in a treaty document which also regulates the rights and duties of citizens, not just with respect to European citizenship, but also with respect to, for example, Justice. Where JHA is concerned, this result acknowledges that the harmonisation of criminal law and criminal procedure and transnational cooperation cannot preclude the harmonisation of principles of due law and fair trial. Despite the substantial Europeanisation of criminal law, many criminal lawyers are defending the achievements and typicalities of their national criminal law like never before. EU initiatives are assessed from the perspective of the national agenda and national achievements. We are still too far removed from a European criminal law policy that is both European and enjoys national support. The core issue is therefore not how to keep our criminal (procedural) law national and free from European influences, but rather how to ensure democratic decision making, the quality of the constitutional state and the guarantees of criminal law in a national administrative model which has to operate increasingly interactively within a European and international context. In this contribution, the contours of the Europeanisation of criminal law are outlined and analysed. First, attention will be paid to the EC and, second, to the JHA. Following this, an evaluation and a look ahead at the current IGC are indicated.

Public Procurement Law and Health care: From Theory to Practice. Research Paper in Law, 2/2010

From the Introduction. This contribution will focus on the core question if, how and to what extent the EU procurement rules and principles (may) affect the national health care systems. We start our analysis by summarizing the applicable EU public procurement legislation, principles and soft law and its exact scope in relation to health care. (section 2). Subsequently, we turn to the parties in a contract, subject to procurement rules in the field of health care, addressing both the definition of contracting authorities and relevant case law (section 3). This will then lead to an analysis of possible justifications for not holding a tender procedure in the field of health care (section 4). Finally, we illustrate the impact of EU public procurement rules on health care by analysing a Dutch case study, in which the question whether public hospitals in the Netherlands qualify as contracting authorities in terms of the Public Sector Directive stood central (section 5). Our conclusions will follow in section 6.

A feigned liberalisation: Russia is restricting Gazprom's monopoly on exports. OSW Commentary No. 121, 26.11.2013

An act restricting Gazprom’s monopoly in Russian gas exports came into effect on 1 December 2013. Previously Gazprom had had a legal guarantee to its monopoly position. The changes are an effect of consultations between various ministries that had been conducted for many months and were affected by lobbying from Novatek and Rosneft (Gazprom’s competitors on the domestic gas market); they need not, though, be seen as system changes. The ‘liberalisation’ they appear to bring in is feigned. Proof of this are found for example in both the limited material scope of the new law (it concerns only exports of liquefied natural gas, LNG) and the small number of the beneficiaries of the new regulations (the new solutions will be beneficial for Novatek and Rosneft). Contrary to initial announcements, the right to export LNG has not been restricted to South-Eastern Asian markets, which means that Russian liquefied natural gas is also likely to be sold to Europe in the coming years. Although these changes have been motivated above all by the individual interests of Gazprom’s competitors, they are also to a certain extent a response to the processes taking place on regional gas markets. They may, therefore, turn out to be beneficial for the state (increasing Russia’s share on the global LNG market and attracting foreign investors to gas extraction projects being implemented in Russia). The new regulations are probably the first step down the long road to breaking Gazprom’s monopoly in gas exports via the pipeline system.
