Regional factors

Naturally, the size of each segment is directly related to the production and particularly the consumption of plastics. The relative growth of the Asia/Pacific area, both as a producer and consumer of plastics, will have a significant effect on additives, and it lies behind the number of mergers and takeovers that are occurring in the additives sector. 

This is clearly driving producers of fillers and additives to follow the polymer producers and adopt a more global outlook, by direct investment in other regions, or by forming partnerships and alliances with local producers in other regions. This has been a key factor behind much of the recent restructuring in the industry.

When fuels are derived from biomass, the net increase in carbon dioxide emitted into the atmosphere is usually considered to be neutral or even negative since the plants used to produce the alcohol fuel have reabsorbed the same or more carbon than is emitted from burning the fuel. The net effect may not be as favorable when the carbon dioxide emitted by equipment for the harvesting of the biomass feedstocks is considered in the balance. Much of this depends on the differences in equipment, farming techniques and other regional factors. 

Give definitions for the following maximum, minimum, optimum, unimodal, multimodal, local optimum, global optimum, continuous, discrete, constraint, equality constraint, inequality constraint, lower bound, upper bound, natural constraint, artificial constraint, degree of freedom, feasible region, nonfeasible region, factor tolerance. 

Lastly, the uneven geographical occurrence of the disease does not suggest hypersensitivity which would presumably be distributed in an even way, but rather suggests that some other regional factor, e.g., infection, is operative.

The infection rate among the population of a country correlates with age, hygiene standards, socio-economic status and individual risk factors (drug addiction, homosexuality, close contact with infected persons, etc.). Men and women are subject to the same frequency of infection, irrespective of age or race and seasonal or regional factors. In Germany, there has been a rapid decrease in natural immunity, because far fewer juveniles become infected with HAV today. Consequently, when people contract the infection at a more advanced age, there is a higher complication rate and greater mortality (2.7% vs. 0.004%). 

The net effect may not be as beneficial when the carbon dioxide emitted by equipment for the harvesting of the biomass feedstocks is considered. This depends on the differences in equipment, farming techniques and other regional factors.
