The author discusses globalisation form multiple perspectives. He emphasises that globalisation certainly reduces poverty in absolute sense while increases poverty in a relative sense. There are important risks inherent in the process of globalisation, which include hyper-competition, treat to the social rights of citizens, and rendering a lot of people economically irrelevant.  To cure the deficiencies of globalisation Professor Zamagni favours cosmopolitical democracy and transnational civil society, which might be able to safeguard cultural diversity, social justice and peace.

Abstract  

Minimizing plutonium measurement uncertainty is essential to nuclear material control and international safeguards. In 2005, the International Organization for Standardization (ISO) published ISO 12183 “Controlled-potential coulometric assay of plutonium,” 2nd edition. ISO 12183:2005 recommends a target of ±0.01% for the mass of original sample in the aliquot because it is a critical assay variable. Mass measurements in radiological containment were evaluated and uncertainties estimated. The uncertainty estimate for the mass measurement also includes uncertainty in correcting for buoyancy effects from air acting as a fluid and from decreased pressure of heated air from the specific heat of the plutonium isotopes.

Abstract  

An advanced neutron activation technique has been developed for the accurate analysis of elemental and isotopic fissile material required in nuclear safeguards, nuclear material standardization and other applications. It is based on reactor neutron flux spectrum differentiation by cadmium screening and multistandard calibration, including the solution of a second order equation system or of computerized calibration curve fitting, taking into account the thermal neutron flux depression. Some discrepancies at high enrichments have still to be eliminated in order to achieve the required measurement accuracy.

Abstract  

The analysis of impurities in uranium matrices is performed in a variety of fields, e.g., for quality control in the production stream converting uranium ores to fuels, as element signatures in nuclear forensics and safeguards, and for non-proliferation control. We have investigated the capabilities of time-of-flight ICP-MS for the analysis of impurities in uranium matrices using a matrix-matched method. The method was applied to the New Brunswick Laboratory CRM 124(1–7) series. For the seven certified reference materials, an overall precision and accuracy of approximately 5% and 14%, respectively, were obtained for 18 analyzed elements.

Abstract  

Decommissioning and decontamination work, safeguards related measurements for special nuclear materials, and many other in-situ applications require that the measuring system be taken to the sample and not the other way around. In addition to a portable detector, these types of measurements need a lightweight, rugged, battery operated MCA. Canberra's solution to this need is the versatile InSpector Multi-Channel Analyzer. This single instrument includes the MCA memory management, a high voltage power supply for either a NaI or a Ge detector, a spectroscopy grade amplifier, a digital stabilizer, and an ADC. It has a total weight of 3,2 kg, including batteries.

Hungary ratified Protocol No. 13 to the European Convention for the Protection of Fundamental Rights and Freedoms concerning the abolition of the death penalty in all circumstances. This event is not a surprise since the Hungarian Constitutional Court declared capital punishment unconstitutional in 1990. Retrospectively, the development of the safeguards against capital punishment in Hungary might seem as a stretch of self-evident consequences. The present paper attempts to situate the decision of the Constitutional Court in its broader context and reflect upon the significance of symbolic founding gestures in times of democratic transition.

Abstract  

The International Organization for Standardization (ISO) Guide to the expression of Uncertainty in Measurement (GUM) was developed to meet the demand for a standardized way of evaluating and expressing uncertainties. The Davies and Gray (D&G) titrimetry method is routinely used in nuclear safeguards for uranium accountability measurement and a statement of the uncertainty that can reasonably be attributed to the measured assay value is therefore of importance. A mathematical model for an uncertainty evaluation of D&G measurements in compliance with ISO GUM is presented. This is illustrated by a numerical example and the utilization of the uncertainty budget is explored.

This paper has been prepared in the hope of giving new insights into the case of C-446/03 Marks & Spencer. The author tries to explore the process of communication in the light of the legal autopoiesis theory, the final result of which is the judgment. Reading it, one can find plain arguments both for the effective protection of EC freedoms, including the freedom of establishment, one the one hand, and for stopping regulatory and tax competition, and safeguarding the national interests of Member States, on the other one. The methodology of legal autopoiesis may be useful in better understanding of the message the judgment has negotiated.

The aim of this paper is to review and emphasize the development of using the comprehensive guidelines for the latest restoration of cultural heritage buildings, in this particular case the Jashar Pasha Mosque in Prishtina, Kosovo. The importance of using specific guidelines for the restoration plans will encourage all responsible bodies to think more in a structural way as far as historical sites and architectural heritage is concerned. This includes the need to assess more profoundly the necessity of using restoration and conservation guidelines towards more successful management of projects of this nature, ensuring the effective and efficient safeguarding of cultural heritage in Kosovo, in general.

Abstract  

A novel method has been developed for the determination of the production date (age) of uranium ore concentrates (yellow cakes). The methodology is based on the measurement of trace-level 232Th and its daughter nuclide, 228Th and their variation over time. The proposed method offers a complementary dating tool to the commonly used 230Th/234U technique, which is applicable, however, only for highly purified materials. Applying the present method it is possible to determine precisely the production date of uranium samples with incomplete separation of their daughter products, such as yellow cakes, other intermediate products or scrap materials for nuclear forensics and safeguards purposes.
