Terrain capability

Terrain capability If possible, the model should be able to simulate processes in complex terrain. 

Terrain capability Capable of treating complex terrain processes. 

In practical applications, dispersion calculations need to be performed in topographically complex environment. Thus, solid obstacles intervening in the area dispersion should be counting in the computations. In previous validation works, it has been proved that CFD codes constitute powerful tools for complex terrain dispersion simulation providing high accuracy results with excellent visualization capabilities, which can be helpful in quantitative risk analysis applications [55]. The dominating mixing mechanism between... 

Generally, the results obtained through the numerical simulation showed good agreement with the experimental data leading to the conclusion that CFD techniques can be effectively used in consequence assessment procedures concerning toxic/flammable dispersion scenarios in real terrains, where box models have limited capabilities. 

Bagnold classifies dunes into two forms, namely, the barchan or cres centic dune and the seif or swordlike dune. The former are perhaps the more basic form since they may be shown to degenerate into the seif type. Dunes are characterized by the fact that they are capable of moving over terrain often without change of form. While the contour of a dune affects the flow pattern of the wind (which in turn affects it), it is possible by a simple analysis to obtain a relationship of other pertinent variables. Let us refer to Figure 114 which illustrates the cross... 

Exploratory drilling in tundra or permafrost areas requires greater care because of the much slower natural recovery capability [68]. Wildcat wells in these areas require more precautions for the handling of warm drilling mud, etc., to avoid terrain collapse from the introduction of a thaw-susceptible area into permafrost [69]. 

Locations of contamination must be precisely marked and mapped so they can be relocated easily. Efficiency in survey and remediation operations is best served through the division of labor, i.e., when the detection and location task is performed separately from access and recovery, which is itself separate from the neutralization or demilitarization of the recovered items. In practice, therefore, an optimal capability would be to quickly mark and later relocate a detection "hit" with an accuracy of a few tens of centimeters, both horizontally and vertically, in a large (thousands of acres) area of reasonably rough terrain. The requisite horizontal resolution might be obtainable with a differential Global Positioning System the vertical resolution is presently not reachable with most detection instruments. 

Water Utilization Efficiency Water will quite definitely be a decisive limiting factor in the worldwide expansion of agriculture (9,54,57,58). It is therefore important that water utilization efficiency be considered in the future screening and development of herbaceous land plants as energy resources. Three factors must be assessed from the onset (a) Utilization efficiency in photosynthetic processes (b) water extracting capability from the candidate species natural terrain and (c), the specibs capacity for water conservation by anatomical means. 

The pulse induction (PI) type of detector pulses a radio frequency signal into the ground and is not affected by iron minerals (negative) and salt water (positive). It is good to use where the terrain varies from wet to dry or where uneven patches of mineral sand are found, as it does not have to be retuned. The PI detector will respond to hot rocks and is unaffected by salt water. The PI detector is often used in underwater configurations. Some larger and newer PI instruments are capable of determining the depth of an object fairly accurately. 

The report further noted the expectation that there would be great variations in state programs due to particular local characteristics, such as the nature of the terrain, the existence of geological or measurement data indicating potential problems, technical uncertainties, differing financial capabilities, and different institutional structures. 

For comparison, with the Pb concentrations of the topmost layers, the solutions collected from the deeper soil horizons all had <1 pg/L and were below the LOD provided by Q-ICP-MS. Hirao and Patterson [125] reported 0.015 pg/L in stream runoff in the Sierra Nevada Mountains, but were only able to accomplish this because of the extreme cautions taken to avoid contaminating their samples with industrial lead, and because they used ID-MS to measure the Pb concentrations. The Sierra Nevada watershed is characterized by granitic rocks, and most of the Pb in uncontaminated streamwater is probably derived from the chemical weathering of biotite and potassium feldspar [126]. Therefore, their measured Pb concentration (15 parts per trillion) is probably not an unreasonable estimate of the natural Pb concentration in uncontaminated waters from crystalline terrains. Thus, any study of soil solution Pb has to be capable of reliably measuring Pb in this concentration range.

Nonarticulated feet are typically the simplest and least expensive. The foot and ankle are combined in a single component, and shock absoiption and ankle motion are provided by the materials and structure of the foot. Since these feet are nonarticulated, diey are quiet and typically require little maintenance. These feet are also cosmetic, lightweight, and provide good shock absorption and limited inversion/eversion on uneven terrain. Disadvantages of nonarticulated feet are the limited range of plantarflexion/dorsiflexion, difficulty with inclines due to heel compression, lack of adjustability for different heel heights, and little torque-absorption capability. 

OSHA requires you to provide a safe work environment for your employees. When working around heavy equipment, your employees are at risk and vulnerable. Bulldozers, dump trucks, cranes, backhoes, and rough terrain forklifts are all capable of injuring or killing them. 

Any Special Features. The formulation should be described for any special features, e.g., the capability to deal with obstacles and/or complex terrain.
