1. The "Green" vs. Trade Debate in the Americas

Author:
Heraldo Muñoz
Source:
Journal of environment & development 1994 v.3 no.1 pp. 109-122
ISSN:
1552-5465
Subject:
environmental protection; sustainable development; trade; North America; South America
Abstract:
... The relationship between trade and the environment has been the subject of lively debate in the Americas and elsewhere. This article analyzes the principal issues involved in the current discussion. Rather than attempting to draw definitive conclusions, the major points ofdebate are highlighted. The chief conclusion is that trade and environmental protection can and should be mutually supportive a ...

Subject:
pupae; imaginal discs; metamorphosis; morphogenesis; mutagenesis; mutants; Plodia interpunctella
Abstract:
... A mutant that results in the reduced length of pupal and adult appendages was isolated from a laboratory colony of the Indianmeal moth, Plodia interpunctella (Hubner). "Reduced appendage" (rda) was determined to be an autosomal recessive mutation that affects the development of pupal and adult appendages during the larval/pupal molt. The rda mutation had no observed effect on the larval phenotype. ...

Abstract:
... The 'Little Ice Age' was an interval between about AD 1500 and 1850, characterized by advancing glaciers in mountainous regions of Europe and western North America. However, it is unclear whether this cool moist period was truly global in extent, or how it was manifested in other regions with different climatic controls. A high-resolution reconstruction of salinity fluctuations in Devils Lake, Nor ...

Genetic studies of the fission yeast Schizosaccharomyces pombe have identified two genes, rad24 and rad25, that are required for this checkpoint. These genes encode 14-3-3 protein homologs that together provide a function ...

Abstract:
... Low molecular weight globulin, which are abundant proteins in the Pinus pinaster Ait. megagametophyte, were purified and characterized. They showed a dimeric structure formed of one large and one small subunit linked by disulfide bridges. They were characterized by a high Arg and Glx content and by a relatively high Cyc content. A comparison of their characteristics with those of angiosperm 2S pro ...

Abstract:
... To assess the extent of inhibitory activity of the host compound 4-allylanisole, we conducted field studies with three scolytid species. These species are geographically widespread and economically important. Trials were completed with Dendroctonus brevicomis LeConte (California), D. ponderosae Hopkins (Oregon), and Ips pini (Say) (Wisconsin) by using multiple-funnel traps with appropriate pheromo ...

Abstract:
... 2,3-Dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one (3) is one of the main products obtained from glucose under the conditions of the Maillard reaction. Heating of 3 in the presence of primary amines leads to the formation of 5-hydroxy-2-methyl-4-(aLkylamino)-2H-pyran-3(6H)-one (11). These new aminoreductones can also be isolated from glucose/amine reaction mixtures. ...

Abstract:
... 6' gentamicin acetyltransferases detoxify aminoglycoside antibiotics containing a 6' amino group. We tested whether a 6' gentamicin acetyltransferase gene (6' gat) of Shigella sp. is suitable as selectable gene in plant transformation using kanamycin (Km) as a substrate. A comparative transformation experiment using Nicotiana tabacum SR1 protoplasts showed that 6' gat is as effective for selection ...
