Like other natural fibers, PALF vary in their properties according to species, geographical regions, age, locations in each plant, and weather conditions among others (Bismarck et al. 2005). There are many different species under the genus of A. comosus, while in the works on PALF and PALF-reinforced polymer composites reviewed, specific species of pineapple from which PALF were extracted were barely mentioned. Only in Bhaduri et al. (1983) the chemical compositions... 

Process Licensors. Some of the well-known nitric acid technology licensors are fisted in Table 3. Espindesa, Grande Paroisse, Humphreys and Glasgow, Rhfyne Poulenc, Uhde, and Weatherly are all reported to be licensors of weak acid technology. Most weak acid plant licensors offer extended absorption for NO abatement. Espindesa, Rhfyne Poulenc, Weatherly, and Uhde are also reported (53,57) to offer selective catalytic reduction (SCR) technology. 

Other factors that affect either production cost or the consumption of fertilisers tend to be periodic and short-Hved. On the consumption side, weather conditions, prices of fertilisers, and the pohtical stabiUty of a region influence demand. The supply side is influenced by raw material availabihty, rehabihty of infrastmcture, on-stream efficiency, age of plants, and the constmction or modernisation of existing plants. 

Important factors to be considered in the study of areas and sites for plant location include raw materials, transportation, process water, waste disposal, fuel and power, and weather. These are discussed individually. 

Moisture must be considered of primary importance in soil formation, in weathering, and in all of the changes taking place within the soil. The types of soil that form depend to a great extent upon the rainfall situation. Too little rainfall will prevent development of plant and animal life with their soil-building action. Too much moisture has a similar effect in preventing normal soil formation. 

Biological and volcanic activities also have roles in the natural mobilization of elements. Plants can play multiple roles in this process. Root growth breaks down rocks mechanically to expose new surfaces to chenaical weathering, while chemical interactions between plants and the soil solution affect solution pFF and the concentration of salts, in turn affecting the solution-mineral interactions. Plants also aid in decreasing the rate of mechanical erosion by increasing land stability. These factors are discussed more fully in Chapters 6 and 7. 

Europe is divided into two zones for the purpose of registration of new plant protection products within its community. The trial location should fall within these two distinct zones, namely the Northern and Central European Zone and the Southern European and Mediterranean zone. The climatic conditions and weather influences within each of the two regions described are assumed to be comparable. However, trial data should be representative of the areas where pesticide use is to be granted. 

Sulfur enters the current geochemical cycle with the weathering of rocks and conversion to either S02 or S042 -bearing species, and subsequent uptake by plants and microorganisms and conversion into a variety of organic forms. Despite the... 

Traditionally, books dealing with sewer systems have been devoted to hydraulics and pollutant transport phenomena. In this context, urban drainage and wet-weather performance, as well as the sewer s interaction with treatment plants and receiving waters, were main focal points. 

Net uptake of heavy metals is due to the removal of heavy metals in crops or trees in the catchment and/or in aquatic plants and fish in a lake. Weathering relates to the... 

Weathering is a major H+ consuming process and pH-buffering mechanism, not only globally and regionally but it also plays a major role in local watersheds in soil processes, in nutrient uptake by plants and in epidiagenetic reactions in sediments.
