| We assess five proposals for the future of the EU greenhouse gas Emission Trading Scheme (ETS): pure grandfathering allocation of emission allowances (GF), output-based allocation (OB), auctioning (AU), auctioning with border adjustments (AU-BA), and finally output-based allocation in sectors exposed to international competition combined with auctioning in electricity generation (OB-AU). We look at the impact on production, trade, CO2 leakage and welfare. We use a partial equilibrium model of the EU 27 featuring three sectors covered by the EU ETS – cement, steel and electricity – plus the aluminium sector, which is indirectly impacted through a rise in electricity price. The leakage ratio, i.e. the increase in emissions abroad over the decrease in EU... |

| Donors support a number of targeted food-based programs in Bangladesh that are widely credited with providing poor people access to food and improving their food security. However, inefficiency in the food distribution system may be hindering the realization of the full benefits of these programs. The International Food Policy Research Institute (IFPRI) conducted a comprehensive study of the efficiency of food distribution in food aid-supported programs in Bangladesh. The study has three components: (1) food discharge at harbors, (2) the public food distribution system, and (3) food distribution to program beneficiaries. The capacity and efficiency of the food distribution system was assessed from entry ports to targeted beneficiaries. The study identified... |

| The Kyoto Protocol represents the first international agreement to reduce greenhouse gas emissions. Proposed mitigation efforts may involve the agricultural sector through such options as planting trees, crop and livestock management changes, and biofuels production. The combined use of these strategies could substantially reduce net emissions of carbon dioxide, methane, and nitrous oxide. However, countries where the Protocol imposes emissions caps have expressed concern about their competitiveness with countries that are not part of the Kyoto Protocol. In a free-trade arena, food production and exports in unregulated countries could increase and reduce market share for the producers in complying countries. We examine the effects of differential Protocol... |

| Atmospheric concentrations of greenhouse gases can be reduced by withdrawing carbon from the atmosphere and sequestering it in soils and biomass. This report analyzes the performance of alternative incentive designs and payment levels if farmers were paid to adopt land uses and management practices that raise soil carbon levels. At payment levels below $10 per metric ton for permanently sequestered carbon, analysis suggests landowners would find it more cost effective to adopt changes in rotations and tillage practices. At higher payment levels, afforestation dominates sequestration activities, mostly through conversion of pastureland. Across payment levels, the economic potential to sequester carbon is much lower than the technical potential reported in... |

| There is widespread recognition that forestry carbon credits can reduce the net emissions of carbon into the atmosphere. Designing systems to sequester carbon, however, has proven difficult due to a number of efficiency issues, including leakage. Leakage occurs when policy makers develop carbon projects in specific places which protect some parcels of land, but leave other parcels of land unprotected. This analysis uses a newly developed model of global land use change from an established forestry and land use model, described in Sohngen et al. (1999); Sohngen and Mendelsohn (2003); and Kindermann et al. (2008). To assess leakage we estimate carbon under storage under one scenario where the world is awarded carbon credits and another where tropical... |

| In comparisons of six seed lots of different F1 hybrid cultivars of cauliflower with similarly high laboratory germinations (above 90%) separation in germination was achieved after controlled deterioration (C.D.) at 24% moisture content (m.c.) and 45 0C for 24 hours. This measure of vigour was related to the position of the lots on the seed survival curve and was highly predictive of the longevity of the lots when stored at 15% m.c. and 20 0C for 12 and 16 weeks. When each seed lot was deteriorated at 24% m.c. for increasing times (from 0 to 36 hours) a reduction in the subsequent percentage germination was seen, which, using probit transformed percentages, was significantly and linearly related to the leakage of electrolytes into seed soak water over 24... |

| A qualidade das sementes colocadas à disposição do produtor é de grande importância para obtenção de altas produtividades. O objetivo do trabalho foi avaliar os efeitos causados por diferentes períodos de envelhecimento artificial na lixiviação de açúcares, proteínas, aminoácidos e íons no exsudato do teste de condutividade elétrica, e suas relações com a germinação e vigor de sementes de feijão da cultivar Pérola. O trabalho foi conduzido no Laboratório da FE de análises de sementes - Unesp Campus de Ilha Solteira. O delineamento experimental foi o inteiramente casualizados, sendo que as sementes foram submetidas a oito períodos de envelhecimento acelerado (zero, 24, 48, 72, 96, 120, 144 e 168 horas). A germinação e vigor de sementes de feijão cultivar... |

| Abstract Pan-drug resistant Gram-negative bacteria, being resistant to most available antibiotics, represent a huge threat to the medical community. Colistin is considered the last therapeutic option for patients in hospital settings. Thus, we were concerned in this study to demonstrate the membrane permeabilizing activity of colistin focusing on investigating its efficiency toward those pan-drug resistant isolates which represent a critical situation. We determined the killing dynamics of colistin against pan-drug resistant isolates. The permeability alteration was confirmed by different techniques as: leakage, electron microscopy and construction of an artificial membrane model; liposomes. Moreover, selectivity of colistin against microbial cells was... |
