Brown Trout Salmo trutta are widely distributed fish that display substantial interpopulation variation in fundamental reproductive traits due to differences in local environmental conditions. This wide variation necessitates regional determination o

Following on from the CGIAR study by Evenson and Gollin (published by CABI in 2003), this volume provides up-to-date estimates of adoption outcomes and productivity impacts of crop variety improvement research in sub-Saharan Africa. The book reports

Potato production is expanding rapidly in developing countries, particularly in Asia. For many poor farmers potatoes represent a staple food and an important cash crop. Potato insect pests have a substantial negative impact on the livelihood of farme

The increasing emphasis on poverty alleviation as a motivation for investing in public-sector international agricultural research is discussed from the perspective of practitioners engaged in ex-post impact evaluation. Context is largely provided fro
Measurements of W gamma and Z gamma production in proton-proton collisions at root s = 7 TeV are used to extract limits on anomalous triple gauge couplings. The results are based on data recorded by the CMS experiment at the LHC that correspond to an

A peaking structure in the J/ψφ mass spectrum near threshold is observed in B ±→J/ψφK± decays, produced in pp collisions at √s=7 TeV collected with the CMS detector at the LHC. The data sample, selected on the basis of the dimuon decay mode

The mass of the top quark is measured using a sample of t (t) over bar candidate events with at least six jets in the final state. The sample is selected from data collected with the CMS detector in pp collisions at root s = 7 TeV in 2011 and corresp

The first measurement of vector-boson production associated with a top quark-antiquark pair in proton-proton collisions at root s = 7 TeV is presented. The results are based on a data set corresponding to an integrated luminosity of 5.0 fb(-1), recor

Invariant mass spectra for jets reconstructed using the anti-k(T) and Cambridge-Aachen algorithms are studied for different jet “grooming” techniques in data corresponding to an integrated luminosity of 5 fb(-1), recorded with the CMS detector in
