Future inequality in Carbon Dioxide emissions and the projected impact of abatement proposals
The authors analyze inequality in future carbon emissions using a group decomposition of the Gini index. Business-as-usual projections to the year 2100 for 135 countries show inequality in per capita emissions declining, but slowly. They also measure the impact on emissions levels and inequality of the Kyoto Protocol and other abatement proposals for Annex II (non-Eastern European high income) countries in 2010, focusing on their gap narrowing and reranking effects. Per capita emissions of Annex II and non-Annex II countries will probably not be substantially reranked unless the Annex II countries reduce their emissions by at least half (from 1990 levels) and emissions from non-Annex II countries continue growing unabated.Climate Change,Montreal Protocol,Global Environment Facility,Environmental Economics&Policies,Sanitation andSewerage,Montreal Protocol,Environmental Economics&Policies,Carbon Policy and Trading,Energy and Environment,Climate Change
No List of Political Assets
Iurii Olesha (1899-1960) was a relative late-comer to film work, if compared to several other important fictional prose writers oft he Soviet ,experimental' (modernist) 1920s. Olesha's first major filmscript (and his first script to be filmed) was "Strogii iunosha (A Strict Youth"), written in Odessa in 29 days in May und June 1934
Estimating the Minimum Number of Individuals (MNI) For Skeletal Collections With Consideration to the Introduction of Procurement Bias
Of the competing methods for the estimation of the number of individuals represented within a skeletal assemblage, variations of the calculation of MNI (Minimum Number of Individuals) are most often employed. This presentation provides the preliminary results of an exhaustive study designed to determine the minimum number of individuals represented within a collection of 1,065 skeletal elements and fragments, belonging to the Eastern Washington University Anthropology Program. Results produced by established methods of computation were reinterpreted to account for the introduction of Procurement Bias in the calculation of MNI
New Stellar Cross Sections and The "Karlsruhe Astrophysical Database of Nucleosynthesis in Stars"
Since April 2005 a regularly updated stellar neutron cross section
compilation is available online at http://nuclear-astrophysics.fzk.de/kadonis.
This online-database is called the "Karlsruhe Astrophysical Database of
Nucleosynthesis in Stars" project and is based on the previous Bao et al.
compilation from the year 2000. The present version \textsc{KADoNiS} v0.2
(January 2007) includes recommended cross sections for 280 isotopes between
H and Po and 75 semi-empirical estimates for isotopes without
experimental information. Concerning stellar cross sections of the
32 stable, proton-rich isotopes produced by the process experimental
information is only available for 20 isotopes, but 9 of them have rather large
uncertainties of 9%. The first part of a systematic study of stellar
cross sections of the -process isotopes Se, Sr,
Pd, Te, Ba, Ba, Dy, and Hf is
presented. In another application \textsc{KADoNiS} v0.2 was used for an
modification of a reaction library of Basel university. With this modified
library -process network calculations were carried out and compared to
previous results.Comment: Proceedings "International Conference on Nuclear Data for Science and

Stellar (n,gamma) cross sections of p-process isotopes PartI: 102Pd, 120Te, 130,132Ba,and 156Dy
We have investigated the (n,gamma) cross sections of p-process isotopes with
the activation technique. The measurements were carried out at the Karlsruhe
Van de Graaff accelerator using the 7Li(p,n)7Be source for simulating a
Maxwellian neutron distribution of kT = 25 keV. Stellar cross section
measurements are reported for the light p-process isotopes 102Pd, 120Te,
130,132Ba, and 156Dy. In a following paper the cross sections of 168Yb, 180W,
184Os, 190Pt, and 196Hg will be discussed. The data are extrapolated to
p-process energies by including information from evaluated nuclear data
libraries. The results are compared to standard Hauser-Feshbach models
frequently used in astrophysics.Comment: 13 pages, 4 figure
V2:Performance of the solid deuterium ultra-cold neutron source at the pulsed reactor TRIGA Mainz
The performance of the solid deuterium ultra-cold neutron source at the
pulsed reactor TRIGA Mainz with a maximum peak energy of 10 MJ is described.
The solid deuterium converter with a volume of V=160 cm3 (8 mol), which is
exposed to a thermal neutron fluence of 4.5x10^13 n/cm2, delivers up to 550 000
UCN per pulse outside of the biological shield at the experimental area. UCN
densities of ~ 10/cm3 are obtained in stainless steel bottles of V ~ 10 L
resulting in a storage efficiency of ~20%. The measured UCN yields compare well
with the predictions from a Monte Carlo simulation developed to model the
source and to optimize its performance for the upcoming upgrade of the TRIGA
Mainz into a user facility for UCN physics.Comment: 23 pages, 8 figure
