Domesticated plants

The nameplate capacity of worldwide methanol plants is given by country in Table 2 (27). A significant portion of this capacity is based on natural gas feedstock. Percent utilization is expected to remain in the low 90s through the mid-1990s. A principal portion of this added capacity is expected to continue to come from offshore sources where natural gas, often associated with cmde oil production, is valued inexpensively. This has resulted in the emergence of a substantial international trade in methanol. In these cases, the cost of transportation is a relatively larger portion of the total cost of production than it is for domestic plants. [Pg.281]

Information on implementation of GMP inspection plans is available in only some of the countries. Where data exist, they indicate that plans were successfully followed or even exceeded their targets. This applies to Cuba, Malaysia, the Netherlands, Uganda, Venezuela and Zimbabwe. For Cyprus, however, inspections of domestic plants fell short of the planned values. Cyprus has 10 domestic manufacturers, and nine inspections were planned, but in 1997 only seven were carried out. The Netherlands has 86 manufacturers and 28 inspections were planned in 1998 all of them were carried out. Venezuela has 41 manufacturers and 23 inspections were planned in 1997, of which 35 were carried out. So a low implementation rate does not necessarily indicate a low inspection rate. Enforcement measures are available in case of non-compliance in Cyprus, Estonia, Malaysia, Tunisia, Uganda, Venezuela and Zimbabwe. In Cuba, no enforcement measures are specified for failure to comply with GMP standards. Comparatively speaking, there is less likely to be a workplan for inspection of distribution channels than there is for GMP inspection. Only four countries — Cyprus, Estonia, Uganda and Venezuela — carry out inspection of distribution channels based on such a plan. [Pg.69]

To most people, sunflower conjures an image of a domestic plant with a large stalk crowned by a single large flower. The wild sunflower, or annual sunflower, however, exhibits a branched growing form with numerous smaller flowers at each branch tip. The average diameter of wild sunflower is about 1 cm, unlike cultivated forms, which commonly reach 30 cm. [Pg.66]

Researchers have mixed responses on the current extent of the air pollution problem in relation to its impact on vegetation. We know that injury occurs in many sensitive native and domestic plant species throughout the country. We do not know how severe the long term pollution effects will be on domestic species, on the frequency or distribution of native species, or on the complex interactions between native species and the effects of these interactions on plant communities. Much research is needed in this area before we can adequately speculate on the future of agricultural production. [Pg.130]

Three major companies accounted for the bulk of US arsenic production in the first half of the twentieth century American Smelting and Refining Co. (ASARCO both copper and lead smelting in several domestic plants), Anaconda Copper Co. (copper smelting), and US Smelting Co. (lead smelting), along with several minor producers. Notably, from 1974 to 1985, the domestic supply of arsenic was controlled by ASARCO, and since 1985 by imports primarily from China, Chile, and Mexico (Mineral Commodity Summaries, 2004). [Pg.306]

A type with ovoid fruits was introduced into South-east Asia initially from India, a globoid-fruited type later from China and the typical European cultivars much later. However, it is cultivated in the region only as a domestic plant. It was also believed that an extract of the whole plant, or fruit, could preserve a person s spirit or essence after death and, for this reason, such compounds... [Pg.190]

The oil palm, Elaeis guineensis Jacq., is grown commercially in Africa, South America, Southeast Asia, and the South Pacific, and on a small scale in other tropical areas. Until recent centuries the palm has been confined to West and Central Africa where it existed in a wild, semiwild, and cultivated state. In Africa it remained a domestic plant, supplying a need for oil and vitamin A in the diet, and it was not until the end of the eighteenth and the beginning of the nineteenth centuries that oil palm cultivation expanded to the Southeast Asian regions and strengthened the entry of palm oil into the world oils and fats trade. [Pg.989]

National security regulations, if they pass, will underscore the need for chemical companies to do more. Current draft regulations could require temporary shutdown of plants that do not meet security standards, and penalties of up to 300,000 per day of noncompliance. In addition, U.S. companies with facilities abroad will have to address vulnerabilities at these plants, which, at this point, may be even more attractive terror targets than domestic plants, Sem says. [Pg.74]

There are many foreign plants, most of them tropical, which contain, or are said to contain, DMT or harmala alkaloids. These are offered for sale from various specialty outlets. Psychotria viridis (a bush) and Banisteriopsis caapi (a large liana) are the two classical ingredients in jungle ayahuasca, but other species are also available. I will not list them here because I have no experience with them and it is my understanding that they require the kind of specialized care which is not a practical option for most North American growers. In any case, the alkaloids they contain are more easily obtainable from domestic plants which have already been described herein. [Pg.216]

Microscopes play a big role in the examples of identification we discuss below -starch grains from South America from early domesticates plants, the introduction of the sweet potato, an important crop, to the islands of the Pacific, and the fine details of floor sediments in prehistoric British Columbia. Finally, a GC/MS identifies chocolate as the contents of ceramic cups found in ancient New Mexico. [Pg.131]

Diet refers to the food and water that we consume to survive. In today s world, where a variety of foods are available at the nearest supermarket, we are a bit removed from tire necessity of finding foods in the wild through hunting and gathering, or cultivating and herding domesticated plants and animals by farming the land. In order to understand past human behavior it is essential that we know what our ancestors ate... [Pg.187]
