Determination of the porosity, permeability and diffusivity of rock in the excavation-disturbed zone around full-scale deposition holes using the -PM…

1998

Abstract Three experimental holes the size of deposition holes in a KBS-3 type repository (depth 7.5 m and diameter 1.5 m) were bored in hard granitic rock in the Research Tunnel at Olkiluoto to study, among other things, the properties of the rock in the excavation-disturbed zone. In the analysis described in this report, the porosities, effective diffusivities and permeabilities of disturbed and intact rock were determined by using two novel methods: the 14 C -polymethylmethacrylate method and the He-gas method. In addition, the structure of the rock in the excavation-disturbed zone was assessed using both scanning electron and optical microscopy.

Field-induced tip–sample oxygen transfer in scanning tunneling microscopy on TiO2(110) (1 1).

2008

International audience; A study on the field-induced tip–surface oxygen transfer at room temperature and its influence on the tunneling conditions for stable STM imaging of the TiO2(110) (1 1) surface is reported. A simple model of field-induced transfer is applied to tungsten and platinum–iridium tips. The oxygen transition rates from the sample to the tip or from the tip to the sample depend on the oxygen desorption barriers formed at tunneling distance. For stable imaging the applied bias voltage has to balance the oxygen transfer probabilities in both directions. In the case of Pt/Ir tips, the tunneling conditions for images with clear evidence of bridging oxygen point defects have been…

Toward a European Eco-label brand for residential buildings: Holistic or by-components approaches?

2011

The Eco-label scheme is becoming ever more important in the environmental certification of products and services, especially in light of the recent ambitious aim of containing greenhouse emissions and improving the efficiency of utilizing energy sources. A recently-introduced hypothesis concerns the European Eco-label scheme relating to buildings, in the awareness that the construction industry is of primary importance to the whole economic and social life of states. This scheme should adopt an integrated approach to environmental problems and include construction, day-to-day management, and the possible disposal of building materials, throughout the life cycle of the building. In addition,…

The Scope of Application of Macrocyclic Polyamines Beyond Metal Chelation

2019

Recent advances in the use of radiometals for both imaging and therapy has spurred on the development of an original chemistry that endows radionuclide-chelating molecular cages with ever sharper physicochemical properties. Macrocyclic polyamines (MPAs) such as cyclen and DOTA are among the most frequently encountered cages for the design of new radiotracers, owing to their versatile chemistry that makes them customizable molecular tools. The idea of using MPAs for alternative purposes has recently emerged, with an eye towards benefiting from their unique topology, versatility, symmetry and water-solubility. This review summarizes strategies that have been recently implemented in which MPAs…

Stretching the limits in help-seeking research: Theoretical, methodological, and technological advances

2011

Abstract This special section focuses on help seeking in a wide range of learning environments, from classrooms to online forums. Previous research has rather restrictively focused on the identification of personal characteristics that predict whether or not learners seek help under certain conditions. However, help-seeking research has begun to broaden these self-imposed limitations. The articles in this special section represent good examples of this development. Indeed, help seeking in the presented articles is explored through complementary theoretical lenses (e.g., linguistic, instructional), using a wide scope of methodologies (e.g., teacher reports, log files), and in a manner which …

Global sensitivity analysis of the A-SCOPE model in support of future FLEX fluorescence retrievals

2014

In support of ESA's Earth Explorer 8 candidate mission FLEX (FLuorescence EXplorer), a Photosynthesis Study has been initiated to quantitatively link fluorescence to photosynthesis. This led to the development of A-SCOPE, a graphical user interface software package that integrates multiple biochemical models into the soil-vegetation-atmosphere-transfer model SCOPE. Its latest version (v1.53) has been successfully verified and was subsequently evaluated through a global sensitivity analysis. By using the method of Saltelli [4], the relative importance of each input variable to model outputs was quantified through first order and total effect sensitivity indices. Variations in leaf area index…

Two Times Four Integrative Levels of Analysis: A Framework

2001

Walsham (2000) urged Information Systems researchers to truly cover all levels of analysis from the individual to the societal in their research agenda. In this paper, we accept his challenge by proposing a research framework offour integrative levels of analysis: individual, group/activity, organizational, and societal. Each level is divided into two viewpoints: intra (single case) and inter (multiple cases, relational, comparative). In addition, the temporal/historical dimension should be applied on all levels and viewpoints. We argue that although all of the levels and viewpoints of the “2 × 4 + history” framework cannot be thoroughly covered in any single study, researchers should alway…

Sanctions for Legal Entities in South American and European Systems of Corporate Criminal Liability

2021

The present analysis of sanctions for cases of liability of legal entities for crimes (corporate criminal liability) adopts a two-fold comparative perspective. First, it focuses on the sanctions provided by the laws of those legal systems, in South America, which introduced such liability, especially in the last two decades after the United Nations’ treaties on organized crime and corruption. Then, it continues with a parallel overview of sanctioning choices in those Member States of the European Union which opted for such liability. The analysis highlights similar and different approaches both in the two contexts and within each of them. Overall, a process of “weak harmonization” of sancti…
