Накопление газообразных продуктов деления и соединений в микрокапсулированном топливе в сверхдлинных кампаниях

The production of b and c quarks in $e^+e^−$ annihilation has been studied with the CELLO detector in the range from 35 GeV up to the highest PETRA energies. The heavy quarks have been tagged by their semileptonic decays. The charge asymmetries for b quarks at 35 and 43 GeV have been found to be $A^b=−(22.2±8.1)$, respectively, using a method incorporating jet variables and their correlations for the separation of the heavy quarks from the back ground of the lighter quarks. For c quarks we obtain $A^c=−(12.9±8.8)$ and $A^c=+(7.7±14.0)$, respectively. The axial vector coupling constants of the heavy quarks c and b are found to be $a^c=+(0.29±0.46)$ and $a^b=−(1.15±0.41)$ taking $B^0 \bar(B^0) B^0\bar(B^0)$ mixing into account. The results are in agreement with the expectations from the standard model

Future cities: 28th eCAADe Conference Proceedings

Future Cities - the title of the 2010 eCAADe Conference describes one of the major challenges of the 21st century. The conference theme is a logical evolution from previous years in that it expands the focus of interest from the building to larger scales and higher complexity. The conference contributions describe methods and instruments that were developed in the last three decades and apply them to city and territorial planning. The eCAADe proceedings demonstrate that CAAD research and education of the past prepared the ground for the future and for the increased responsibility of the CAAD community
