Recent Electroweak Results from the Tevatron

Recent electroweak results from the CDF and D0 Collaborations at the Fermilab Tevatron Collider are presented. After a brief description of the \D0 measurements of W/Z production cross sections, W width, W mass and W \to \tau \nu decays, the CDF result on W(pT) distribution is outlined. The comprehensive search for anomalous gauge couplings by \D0 in 1992-96 data is presented along with a detailed description of the WW/WZ \to \mu\nu jj channel.Comment: 7 pages, 6 figures, Postscript file available from http://phyun0.ucr.edu/~gounder/Public/ewpaper.p

The Role of the Food & Beverage Sector in Expanding Economic Opportunity

The food and beverage industry has a unique role in expanding economic opportunity because it is universal to human life and health. The industry operates at multiple levels of society where billions of people grow, transform, and sell food, particularly in developing countries where agriculture dominates all other economic sectors. Yet a vast share of these workers cannot both satisfy their immediate consumption needs and earn sufficient income from food markets to improve their lives. This report applies the results of primary and secondary research to a number of case studies to draw lessons on strategies for expanding economic opportunity in the food & beverage sector. Primary research consisted of telephone interviews and secondary research included a review of reports, studies, and articles from a range of sources for each case study. The result is a paper that provides insight into how pioneering large firms are breaking this dilemma and building economic opportunity around food beverage value chains

Structural analysis of outer membrane beta-stranded porins using B-factor

Computational and statistical analysis has formed a large component of the biophysical efforts put forth to understand protein structure and function, due to the diversity and complexity of their structure. Outer membrane proteins form a diverse and complex set of proteins. Of these, porins that allow passage of molecules across the membrane interface have been analyzed here from a biophysical and structural perspective. The objective of this study is to analyze the structural organization of porins using atomic temperature factor as a parameter. Generally atomic temperature factors of molecules from crystal structures indicate the degree of mobility or disorder seen in the crystal structure. As good crystal structures have lesser possibilities of errors so there is lesser chance that errors are playing roles in temperature factors. Structures of six porins (four 16-stranded beta barrel porins and two 8-stranded beta barrel porins) were taken from the PDB for the analysis based on resolution and R-factor. Programs and scripts were written for extracting the temperature factors for the beta strands, loops and turns so that the analysis could be done for different atom-types and residue-types. The residue distribution and mobility distribution was found to be characteristic of each of the porins. The mobility and residue distribution amongst the secondary structural elements were found to follow the level of homology at the sequence and structural level. The loops that had defined functional roles in structural terms were found to have lower temperature factors than the other loops. The turn regions that are thought to face the periplasmic region in the cell, showed higher temperature factors. For both the 16 stranded and the 8-stranded barrels it was found one part of the barrel (the lower wall or 'inner' wall comprising the trimer interface in the case of the 16-stranded barrels) was more rigid and the other half of the barrel (the higher or 'outer' wall) showed more mobility as seen from the temperature factors. This seems to be an intrinsic structural component of the beta barrels

Legal and Policy Framework for Promoting Equitable Access to Documentary Heritage

The National Mission for Manuscripts of India, in association with UNESCO, completed a research study to assist in the development of legal and policy framework and protocols for promoting equitable access to documentary heritage, relevant to India and other South Asian countries. This study report seeks to accurately identify and critically examine the legal and policy framework for promoting equitable access to our documentary heritage. The National Mission for Manuscripts is the most important institution in India creating bibliographic databases of manuscripts and engaged in the conservation and preservation of valuable manuscripts. This report engages with the legal and policy framework which envelops the lifecycle of the Mission’s work: the process of access to manuscripts, digitization of manuscripts and the creation of databases. By critically examining the legal rules in the practical context of the Mission’s work, the research team has put together the first such review of any such initiative in the protection of traditional knowledge in the country. The conclusions of the report are in the form of draft legal agreements and policy recommendations located in the discussion on various parts of the Mission’s work. While this report does not set out to be the final word on these significant policy initiatives, the report definitely makes significant progress in the policy debate and legal literature in this field. This report illustrates working patterns of the Mission within the legal and policy framework in the Country. This report will be a valuable sourcebook for understanding South Asian legal and policy framework for accessing documentary heritage collections. The draft legal agreements and policy recommendations, presented in this report, will also be valuable intervention tools for South Asian countries that share similar legal and policy framework within the sub-region
