Figure 2 illustrates the economic structure of the economies of the District , Northern Virginia , Suburban Maryland and the U.S. in 1991 using personal income as an indicator of the size of different sectors , The data show that the whole National Capital Region may be described as a government , and business and technical services center and that manufacturing is relatively unimportant , When the services are examined in more detail ( Figure 3 ) notable differences appear . The prices in the New York City area show that , since 1997 , natural gas has generally been less expensive than distillate fuel but more costly than residual fuel oil ( Figure 6 ) . In Taiwan , pear leaf scorch has been attributed to X. fastidiosa , and in Brazil and Argentina , X. fastidiosa-caused citrus variegated chlorosis ( figure 16 ) has become a major limitation to citrus production , and the same pathogen was identified as the causal agent of a leaf scald of coffee . Nevertheless , the obvious differences in cluster patterns between different SNPs can be explained by variations in sequence context ( Figure 4 ) , affecting hybridization of extension primers to the target molecules and to the spotted signature tags . There are three primary bins and three secondary bins in the composter ( Figure 1 ) . O. cernua is a major constraint on production , especially in Bulgaria where sunflower is the source of the national cooking oil ( Figure 31 ) .
