Are high-temperature fractionations in the solar nebula preserved in highly siderophile element systematics of the Earth's mantle?
2004
The relative abundances of the highly siderophile elements (HSE) Os, Ir, Ru, Pt, Rh, and Pd in relatively pristine lherzolites differ from solar abundance ratios and are several orders of magnitude higher than predicted for equilibrium distribution between metal/silicate (core-mantle). The samples are characterized by a mean Ca/Al ratio of 1.18 ± 0.09 σM and a mean Ca/Si ratio of 0.10 ± 0.01 σM, overlapping with a mean Ca/Al of 1.069 ± 0.044 σM and a mean Ca/Si of 0.081 ± 0.023 σM found in chondrites (Wasson and Kallemeyn 1988). Interestingly, the CI-normalized abundance pattern shows decreasing solar system normalized abundances with increasing condensation temperatures. The abundance of …
Looking for the origin of life in cosmochemistry : asteroids and their carbon-rich meteorites
2015
Carbonaceous chondrite meteorites are carbon-containing fragments of primitive asteroids that have offered the only samples available to date giving insights into chemical evolution in laboratory analyses. Their study has revealed that abundant organic chemistry came to be in the Solar System ahead of terrestrial life and, by the input of these meteorites and comets, might have aided in the origin of our planet’s biochemistry.
The choice of a solid waste management system using the Electre II decision-aid method
1995
A multicriteria decision-aid method, Electre II, was applied to the real choice process of a solid waste management system in the Uusimaa region, Finland. The criteria used were chosen by a supervision group. The weights of the criteria were defined by the managers of environmental and technical affairs of each municipality in Uusimaa, Finland. The use of the Electre II method leads us to recommend centralized incineration as the best municipal solid waste management system for the planning region. However, the second best alternative, intermediate RDF combustion with intermediate landfilling was finally chosen by the municipalities.
ELECTRE III and IV Decision Aids in an Environmental Problem
1997
This paper gives a description and analysis of the use of ELECTRE III and IV decision aids in the context of choosing a solid waste management system in two different real applications in Finland. Both methods fit this context well in general, since the problem involves many criteria and many ‘decision makers’. The available data are imprecise, which also favours the use of outranking methods. In addition to the real applications, we also study the choice behaviour offered for decision makers in connection with these methods by looking at some test results obtained from randomly generated problems. In general, the results of ELECTRE III and IV do not differ substantially from those from the…
Recurrence of hepatocellular carcinoma after liver transplantation: an update.
2015
Liver transplantation is the only curative alternative for selected patients with hepatocellular carcinoma (HCC) who are not eligible for resection and/or with decompensated cirrhosis. According to Milan criteria the 5-year survival rate is 70–85%, with a recurrence-free survival of 75%. However, HCC recurrence rate after liver transplantation remains a significant problem in the clinical practice. The prognosis in patients with HCC recurrence is poor. The treatment of choice for HCC recurrence is surgery, but it seems that a systemic treatment based on combination of an mTOR inhibitor with sorafenib can be used. Data on safety and efficacy are limited, clinical monitoring is necessary. Th…
