The enthalpy hberated on the VDP of parylene is real and in an adiabatic situation causes a rise in temperature of the coated substrate. For Parylene C, 229.1 kj/mol (54.7 cal/mol) corresponds to 1654 J/g (395 cal/g) whereas its specific heat at 25°C is only 1.00 J/(g-K) [0.239 cal/(g-K)] (33). In most practical situations, however, the mass of parylene deposited is dwarfed by the substrate mass, and the heat of polymeriza tion is dissipated within the coated substrate over the time required to deposit the coating with minimal actual temperature rise. 

Based on these fundamental pieces of information, the material is used on ornamentals to reduce height, producing compact plants. Additional side effects ate improved bud set and color. Experimentally, the compound has been used to dwarf fmit trees which has led to increasing the aveal planting number. 

Dwarf tapeworm (Fpiimenolepis nand) is the only human tapeworm that does not uti1i2e an intermediate host. Infection is transmitted directly from person to person, fi nana is only 2—4 cm long, it is of universal distribution in mice and humans in temperate 2ones, where children, especially those in institutions, are most frequently infected. Although an infected person is often symptomless, this tapeworm can cause abdominal discomfort and diarrhea if infection is heavy. 

Operating Costs Power cost for a continuous thickener is an almost insignificant item. For example, a unit thickener 60 m (200 ft) in diameter with a torque rating of 1.0 MN-m (8.8 Mlbf in) will normally require 12 kW (16 hp). The low power consumption is due to the very slow rotative speeds. Normally, a mechanism vi l be designed for a peripheral speed of about 9 m/min (0.5 ft/s), which corresponds to only 3 r/h for a 60-m (200-ft) unit. This low speed also means veiy low maintenance costs. Operating labor is low because little attention is normally required after initial operation has balanced the feed and underflow. If chemicals are required for flocculation, the chemical cost frequently dwarfs all other operating costs. 

The agricultural emissions of NHj, NjO and NO must be considered in context the processes which lead to net loss from the soil and vegetation are natural and form a part of the land-atmosphere cycling of this vital nutrient. The current agricultural processes, however, create conditions in which the small natural background fluxes, in the range of a few ngNm s are dwarfed by losses from fertilized land.

The evolution of a. star after it leaves the red-giant phase depends to some extent on its mass. If it is not more than about 1.4 M it may contract appreciably again and then enter an oscillatory phase of its life before becoming a white dwarf (p. 7). When core contraction following helium and carbon depletion raises the temperature above I0 K the y-ray.s in the stellar assembly become sufficiently energetic to promote the (endothermic) reaction Ne(y,a) 0. The a-paiticle released can penetrate the coulomb barrier of other neon nuclei to form " Mg in a strongly exothermic reaction ... 

World production of synthetic ammoma hos increased dramatically particularly during the period 1950-80. Production in 1950 was Mule more ihan 1 million tonnes, thou this was huge when compared with the production of most o r compounds, it is dwarfed by today s rale of production which exceeds 120 million tonnes pa. In 1990 world production capacity was 119.6 million tunoes distributed os follows Asia 35.4%, the former Soviet Umon 21,5%. North America 13 8%, Western Europe 11.3%, Ea rem Europe 9.7% Latin America 5.3%, Africa 30%. The price of NH3 (FOB Gulf Coast plants, USA) was l07/tonne in 1990. 

Chlorine is the twentieth most abundant element in crustal rocks where it occurs to the extent of 126 ppm (cf. nineteenth V, 136 ppm, and twenty-first Cr, 122 ppm). The vast evaporite deposits of NaCl and other chloride minerals have already been described (pp. 69, 73). Dwarfing these, however, are the inconceivably vast reserves in ocean waters (p. 69) where more than half the total average salinity of 3.4 wt% is due to chloride ions (1.9 wt%). Smaller quantities, though at higher concentrations, occur in certain inland seas and in subterranean brine wells, e.g. the Great Salt Lake, Utah (23% NaCl) and the Dead Sea, Israel (8.0% NaCl, 13.0% MgCU, 3.5% CaCU).

Despite vast efforts over 20 years, rice remains one of the most salt-sensitive of crops. Efforts have centred on screening the existing germplasm, and the more resistant varieties have proved to be older, traditional (and therefore non-dwarfed) land races. Although some of their resistance has been incorporated into modern varieties, these have not increased in resistance beyond that of their parents, and do not achieve the resistance of barley or wheat (Ponnamperuma, 1984).
