Morphological and environmental data

The most important morphological and environmental data relate to  [Pg.49]

These data, including the physical or numerical model, may also be used as input for an environmental impact assessment. [Pg.49]

As a result of the presence of suspended particles, water will lose its transparency. Increased turbidity levels will alter local primary photosynthesis processes. Consequently, the oxygen and temperature levels of a water body may be affected. [Pg.49]

Because the amount of suspended particles corresponds to the intensity of scattered light, a turbidity measurement can quickly provide an estimate of the amount of suspended solids in a water body. [Pg.50]

Background turbidity data relate to the measurement of the concentration levels of suspended material in the water column prior to dredging. [Pg.50]


This section gives an overview of hydraulic, meteorological, morphological and environmental data that are relevant for dredging and reclamation projects. The... [Pg.44]

Stratum corneum, the outermost layer of mammalian epidermis, functions physiologically as the principal diflFusion barrier to molecules penetrating the skin and as a protective physical barrier to mechanical insults at the skin surface. Data suggest that these functions are critically dependent on the specific morphological and macromolecular organization of the membrane mosaic (16, 17, 18, 19, 20). Thus, alterations of biophysical properties arise from environmental factors acting directly on the membrane or upon the keratinization process, and they affect... [Pg.75]

In this study, a simple and brief technique provided results comparable to published data dependent upon to dark-adapted state. Morphological aspects of ERGs using subcutaneous electrodes are similar to ERGs using comeal lens electrodes. It seems that the effects of mechanical and environmental variables are minimized in this procedure. Artefacts seems to have a negligible occurrence. [Pg.97]

With this priority in mind, we are faced with the convergence of two historical trends. If Floras are to be at the forefi-ont of plant conservation activities, they need to be both encyclopaedic and concise. Ecologists, climate modellers, environmental scientists and land managers require detailed data on distribution, morphology and physiology. They also require concise, speedy, accessible means to effect accurate species identifications. If they are to warrant Wheeler s (2004) call for a funding shift... [Pg.17]

Note that extensive experimental data are not available to document changes in catalyst morphology for SCR and VOC catalysts in comparison with decreasing catalytic activity. These environmentally significant catalytic applications are still in their infancy as the bases for published fundamental investigations. Further, those data that are available in the open literature often are not analyzed in detail, as discussed below. [Pg.137]

Abstract We present an overview of statistical thermodynamic theories that describe the self-assembly of amphiphilic ionic/hydrophobic diblock copolymers in dilute solution. Block copolymers with both strongly and weakly dissociating (pH-sensitive) ionic blocks are considered. We focus mostly on structural and morphological transitions that occur in self-assembled aggregates as a response to varied environmental conditions (ionic strength and pH in the solution). Analytical theory is complemented by a numerical self-consistent field approach. Theoretical predictions are compared to selected experimental data on micellization of ionic/hydrophobic diblock copolymers in aqueous solutions. [Pg.57]

On the one hand, molecular taxonomy helps morphological taxonomy to reveal species complexes and potentially identify the correct units of diversity (e.g. Pons et al., 2006 Burns et al., 2008) on the other hand, environmental sequencing by cloning PCR products but mostly by ultrasequencing, is providing distributional data of many taxa otherwise unrecorded or undistinguished (e.g. Robeson et al., 2009 Creer et al., 2010). [Pg.5]

Generally, some varieties of kenaf can be found in Malaysia. These types may differ in terms of color of stem, shape of the leaf, color of the flower and seed, as well as its suitability in different environmental conditions. Kenaf sp. V36 is a kenaf variety that is widely planted in Malaysia. It is formd to be the most applicable type of kenaf for commercial use [24]. H ng et al. have examined nine varieties of kenaf including the V36 type, especially in terms of their anatomical appearance as well as cell morphology [32]. They have found that all kenaf varieties have slight differences in their length, fiber and lumen diameter. The mean values of fiber length, fiber diameter and fiber cell wall thickness of V36-type kenaf are shown in Table 22.4. Recent data reported by Nayeri et al. [33] are comparable to those published by H ng et al. [32]. [Pg.506]
