The United States continued fast-breeder reactor research and development with the building of the fast flux test faciHty (FFTF) at Hanford and the SEFOR reactor in Arkansas (59). The next plaimed step was to build a prototype power reactor, the Clinch River fast-breeder plant (CRFBP), which was to be located near Oak Ridge, Teimessee. 

Continuous vacuum pans have been successhiUy developed for raw sugar crystallization, and are widely appHed in South Africa, AustraHa, South America, and the United States. Continuous crystallizers, developed for beet sugar manufacture, are being adapted for use in cane sugar factories. 

The most widely used submerged-culture oxidizer is the Brings acetator (50). It uses a bottom-driven hoUow rotor turning in a field of stationary vanes arranged in such a way that the air which is drawn in is intimately mixed with the Hquid throughout the whole bottom area of the tank (51,52). In the United States, continuous cavitator units are used widely for cider-vinegar production. 

Over the next two decades, oil production within the United States continued a generally upward path as producers discovered new fields and worked established fields more intensely. By 1929, total U.S. oil output exceeded the one billion barrel per year level. Despite the Depression, and in part due to the still growing demand for automotive gasoline, oil production grew over 39 percent over the following twelve years, topping off at over 1.4 billion barrels in 1941. 

In many ways, both Canada and the United States continue to be involved in a unique experiment of co-operative management of serious environmental issues which plague a shared international resource. Despite the institutional complexity and the history of abuse that man s activities have wrought on the Great Lakes, the experiment to restore and protect them has had several successes typhoid and cholera were eradicated eutrophication problems are now largely under control and where adequate control programs for toxic chemicals have been implemented and enforced (e.g., mercury, DDT, PCBs), there have been associated declines in concentrations in the lakes. These successes have been due in no small way to the spirit of co-operation that has continued to exist between Canada and the United States and the unique institutional arrangements entered into by the two countries.

The war on terrorism has had conflicting effects on the war on drugs. For example, when the anti-terrorism efforts following September 11, 2001, led to stricter inspections along the Mexican border, drug smuggling did decline somewhat. But as cocaine became scarcer, the production of methamphetamines in criminal labs inside the United States continued to grow. 

A total of 527 million pounds and 747 million pounds of aluminum were exported by the United States in 1972 and 1975, respectively. More recently, total exports of aluminum from the United States continued to increase in 1995, reaching their highest level since 1991 (USGS 1996, 1997a). Export volumes in thousand metric tons were 1,760 (3.9 billion pounds), 1,450 (3.2 billion pounds), 1,210 (2.7 billion pounds), 1,370 (3.0 billion pounds), 1,610 (3.5 billion pounds), 1,500 (3.3 billion pounds), and 1,600 (3.5 billion pounds) (January through November total) from 1991, 1992, 1993, 1994, 1995, 1996, and 1997, respectively (USGS 1996, 1997a). 

Free world petroleum coke production has increased dramatically in the past decade. The United States continues to be a dominant factor in the petroleum coke industry, accounting for more than 75% of the total production. 

But even if the United States continues to make many of the scientific discoveries, and even if American firms were to be the first to introduce innovative new products based on superconductivity, Japanese companies could still take the lead in commercialization, as they have done in consumer electronics. Relatively quickly, the competition would come down to a matter of engineering skills and manufacturing know-how—the latter being especially important since the new high-temperature materials are difficult to work with. And in these areas, the Japanese compa-...

Once the diagnosis of VTE has been confirmed objectively (see Clinical Presentation and Diagnosis section), anticoagulant therapy with either UFH, LMWH, or fondaparinux should be instituted as soon as possible. Although LMWHs and fondaparinux are highly effective and can be administered in the outpatient setting, most patients in the United States continue to receive intravenous UFH for the initial treatment of VTE." The decision to initiate therapy with an LMWH or fondaparinux on an outpatient basis should... 

Surveillance data indicate that the incidence of certain OIs in HIV-infected persons in the United States continues to change. The three major OIs—Pneumocystis carinii pneumonia (PCP), Mycobacterium avium complex (MAC) disease, and cytomegalovirus (CMV) retinitis—all have decreased in incidence. Potent antiretroviral reg-... 

The United States continues to have the largest methanol capacity of any area of the world. However, within the past 20 years, large increments of capacity have been added in various other areas (see Table 6.8). Almost any country (or area) that has a ready supply of cheap natural gas has endeavored to exploit this re-...

Conventional (primary and secondary) recovery methods recover only a small fraction of the crude oil originally in place in a typical reservoir. The primary and secondary recovery techniques, which include pressure maintenance by gas injection and water flooding for improved recovery, leave approximately two-thirds of the original oil in the reservoir. As the conventional oil production of the United States continues to decline, enhanced oil recovery will play an important role in the utilization of our domestic resources. Conventional methods do not overcome the basic problems of oil being trapped within the rock pores and of the low mobility of the remaining oil. 

The future of soybean production and soybean utilization is bright because of the growing demand for protein. The United States continues to be the world s largest soybean producer with some of the world s lowest operating and logistics costs. New opportunities emerged with biodiesel that portend a significant new market for soybean oil. 

No adoption of compatible procedures has been reported recently. Canada and the United States continue to use different measurement procedures for dry deposition of sulphates.
