Magnesite Deposits of Central Ceará, Brazil (open access)

Magnesite Deposits of Central Ceará, Brazil

From introduction: The purpose of this study was to investigate the quantity and quality of [Central Ceara, Brazil] magnesite, and the writer concludes that this group of deposits constitutes one of the major reserves of high-grade magnesite in the Western Hemisphere. The ore could be used in the production of any commercial grade of magnesia with little or no beneficiation. Soil and alluvial overburden is thin between widespread outcrops, so all the deposits could be mined from open pits.

Carbon emissions and sequestration in forests: Case studies from seven developing countries (open access)

Carbon emissions and sequestration in forests: Case studies from seven developing countries

Deforestation in Brazilian Amazonia in 1990 was releasing approximately 281--282 X 10{sup 6} metric tons (MT) of carbon on conversion to a landscape of agriculture, productive pasture, degraded pasture, secondary forest and regenerated forest in the proportions corresponding to the equilibrium condition implied by current land-use patterns. Emissions are expressed as committed carbon,'' or the carbon released over a period of years as the carbon stock in each hectare deforested approaches a new equilibrium in the landscape that replaces the original forest. To the extent that deforestation rates have remained constant, current releases from the areas deforested in previous years will be equal to the future releases from the areas being cleared now. Considering the quantities of carbon dioxide, carbon monoxide, methane, nitrous oxide, NO{sub x} and non-methane hydrocarbons released raises the impact by 22--37%. The relative impact on the greenhouse effect of each gas is based on the Intergovernmental Panel on Climate Change (IPCC) calculations over a 20-year time period (including indirect effects). The six gases considered have a combined global warming impact equivalent to 343 to 386 million MT of C0{sub 2}-equivalent carbon, depending on assumptions regarding the release of methane and other gases from the various sources …

Uraniferous Coal and Carbonaceous Shale in Northeast Paraná, Brazil (open access)

Uraniferous Coal and Carbonaceous Shale in Northeast Paraná, Brazil

From abstract: Uraniferous coal has been found in northeast Parana', Brazil, in the Rio Bonito formation of Pennsylvanian age. In the majority of coal samples taken the uranium oxide content ranges from 0.005 to 0.030 percent, but selected screened samples have contained as much as 0.45 percent uranium oxide. The sampled thickness of the coal seam ranges from 17 to 54 centimeters and averages 31 centimeters. Channel samples across the entire thickness of the coal zone were taken in two places. All other samples were taken as grab samples from either mine waste dumps or coal zones that had high radioactivity.

Reconnaissance for Uranium in the Coal of São Paulo, Santa Catarina, and Rio Grande do Sul, Brazil (open access)

Reconnaissance for Uranium in the Coal of São Paulo, Santa Catarina, and Rio Grande do Sul, Brazil

Abstract: Uranium-bearing coal and carbonaceous shale .of the Rio Bonito formation of Pennsylvanian age have been found in the States of Sao Paulo, Santa Catarina, and Rio Grande do Sul, Brazil. The uranium oxide content of the samples collected in the State of Sao Paulo ranges from 0.001 percent to 0.082 percent. The samples collected in Santa Catarina averaged about 0.002 percent uranium oxide; those collected in Rio Grande do Sul, about 0.003 percent uranium oxide. Since the field and laboratory investigations are still in their initial stages, only raw data on the radioactivity and uranium content of Brazilian coals are given in this report.

Brazilian Trade Policy and the United States (open access)

Brazilian Trade Policy and the United States

As the largest and one of the most influential countries in Latin America, Brazil has emerged as a leading voice for developing countries in setting regional and multilateral trade agendas. Brazil is critical of U.S. trade policies such as the Byrd Amendment (repealed, but program in effect until October 1, 2007), which directs duties from trade remedy cases to affected industries, the administration of trade remedy rules, and what it considers to be discriminatory treatment in the U.S. expansion of free trade agreements in Latin America. Despite the differences, both countries recognize the potential for important gains to be had from mutually acceptable trade liberalization at all levels.

A Free Trade Area of the Americas: Major Policy Issue and Status of Negotiations (open access)

A Free Trade Area of the Americas: Major Policy Issue and Status of Negotiations

In 1994, 34 Western Hemisphere nations met at the first Summit of the Americas, envisioning a plan to complete a Free Trade Area of the Americas (FTAA) by January 1, 2005. Faced with deadlocked negotiations, the United States and Brazil, the FTAA co-chairs, brokered a compromise at the November 2003 Miami trade ministerial. It moved the FTAA away from the comprehensive, single undertaking principle, toward a two-tier framework comprising a set of "common rights and obligations" for all countries. This report follows the FTAA process and will be updated periodically.
