The coloured quantum plane

We study the quantum plane associated to the coloured quantum group GL_{q}^{\lambda,\mu}(2) and solve the problem of constructing the corresponding differential geometric structure. This is achieved within the R-matrix framework generalising the Wess-Zumino formalism and leads to the concept of coloured quantum space. Both, the coloured Manin plane as well as the bicovariant differential calculus exhibit the colour exchange symmetry. The coloured h-plane corresponding to the coloured Jordanian quantum group GL_{h}^{\lambda,\mu}(2) is also obtained by contraction of the coloured q-plane.Comment: 10 pages, (AMS)LaTeX, to appear in J.

CMS Pixel Detector Upgrade

The present Compact Muon Solenoid silicon pixel tracking system has been designed for a peak luminosity of 1034cm-2s-1 and total dose corresponding to two years of the Large Hadron Collider (LHC) operation. With the steady increase of the luminosity expected at the LHC, a new pixel detector with four barrel layers and three endcap disks is being designed. We will present the key points of the design: the new geometry, which minimizes the material budget and increases the tracking points, and the development of a fast digital readout architecture, which ensures readout efficiency even at high rate. The expected performances for tracking and vertexing of the new pixel detector are also addressed.Comment: 5 pages, 7 figures, Proceedings of the DPF-2011 Conference, Providence, RI, August 8-13, 201

Use of Ecolabels in Promoting Exports from Developing Countries to Developed Countries: Lessons from the Indian LeatherFootwear Industry

This paper tries to understand whether importers in the North are able to push exporters in the South towards sustainable production, with the help of a case study of the Indian leather industry. After providing a short description of the global leather footwear industry, the first section provides insights into the competitive advantages of different countries, characteristics of developing country exporters and the difference between large and small European buyers of Indian leather footwear. The subsequent section provides an insight into the different chains of influence that exist in trying to make international trade more sustainable with the help of a broad understanding of the means, their effectiveness, their constraints and a few examples of such chains of influence. Section four studies whether ecolabels are in a position to be suitable indicators of sustainability. Further it delves into understanding the perspectives of consumers, producers and regulators on whether ecolabels are useful in promoting sustainable exports. The explanation of how ecolabels conflict with brand dynamics is quite interesting. The policy measures provide clear options for targeting sustainable production. Suggestions include use of eco-elasticity indicator, toolbox approach to environment policy, introducing comprehensive sustainability labels, maintaining a level of mandatory legislations as well as a constructive effort to increase transparency in supply chains. The annexure include the research methodology adopted for the paper, the reason for choosing Europe as destination for the research, a brief overview about types of ecolabels and a small description of integrated product policies.Ecolabels, Export promotion, Leather footwear, Market access
