Grain active

Based on the following assumptions 50 cm of saturated regolith (mantle rock), 0.5 m g" surface area of mineral grains, 40% of mineral grains active in weathering, density of minerals = 2.5 g cm ... 

There are several alternatives for the mapping of predefined partial workflow processes into dynamic task nets. On the one hand, the whole workflow process can be represented as a single task in the dynamic task net. Its activation reflects the start of the workflow instance within the workflow management system, while the termination of this task reflects the termination of the work-flow instance. In this case, the fine-grained activity structure of the workflow process is hidden black-box approach). This simple form of integration is sufficient in many situations, but because of the encapsulation it is impossible to monitor the progress of the activities in the workflow process within AHEAD. 

On the process side we have the working area model, being a part of the domain knowledge. Furthermore, we have the organization-dependent result processes model, and the fine-grained activity model. 

Process-centered, fine-grained technical tool support (see Sects. 3.1 and 2.4) needs the knowledge contained in the fi.ne-grained activity model. Indirectly, also, the middle-grained result process model is necessary, in order to see in which or between which documents the fine-grained support is to take place. As fine-grained operations also take the state of documents into account, the document contents model is needed as well.

Liquid phase adsorption is used mainly to bind turbid substances, to purify and decolor solutions, and to separate organic pollutants. Grained active carbon is employed as an adsorbent, mixed in a pulverized form with the liquid or as particles in a percolation process. 

A schematic for wastewater treatment by adsorption of waste substances, for example, is shown in Fig. 4-5. The adsorption process is carried out discontinuously with grained active carbon or continuously with grained or pulverized active carbon. 

Foods high ia sucrose, proteia, or starch (qv) tend to biad water less firmly and must be dried to a low moisture content to obtain microbial StabiHty. For example, grain and wheat flour can support mold growth at moisture contents above 15% (wet basis) and thus are stored at moisture contents below 14%. Stored grains and oil seeds must be kept at a water activity below 0.65 because certain molds can release aflatoxias as they grow. Aflatoxins are potent carciaogens (see Food toxicants, naturally occurring). 

Phytic acid (9), although restricted to a more narrow range of food products, mainly grains, complexes a broader spectmm of minerals than does oxahc acid. Decreased availabiUty of P is probably the most widely recognized result of excessive iatakes of phytic acid, yet Ca, Cu, Zn, Fe, and Mn are also complexed and rendered unavailable by this compound (47—49). Phytic acid has also been reported to reduce the activity of a-amylase and to decrease the activity of both proteolytic and Hpolytic enzymes (50).
