Mechanisms of Movement

The seabed characterization consists of identifying the type of failure (i.e., rotation, translational, or flow), sediment stratification, and type of sediments involved. External loading can be caused by a variety of factors both man-made (i.e., construction operations or structures) or natural (i.e., waves, currents, seismic, and rapid sediment deposition). 

Analysis of instability based on the above involves considering both static and dynamic loading for both the cases of total and effective stresses. The characterization of total and effective stress analysis is presented in Table 11.2 (Chaney, 1984).

The mechanism of movement in blue-green algae is still hypothetical (cf. reviews by Walsby13 ), Castenholz12) Fogg et al.31)). 

The mechanism of movement is attributed to the rupture of oxygen bubbles creating a propulsive force driving the PDMS boat forward at the air/water interface. 

The mechanism of movement was also confirmed to be similiar. Catchmark was able to control hydrophobicity of the gold through different wet chemistries, thereby demonstrating that a hydrophobic gold surface is necessary for movement to occur. This is in agreement with the interfacial tension gradient concept in that a hydrophobic gold surface is necessary to observe platinum end forward movement. 

The anti-invasive activity of avinosol was examined using two human tumor cell lines that show distinct mechanisms of movement through the extracellular... 

Circulation Rates of Elements. The concept of cycling of individual elements, in part coupled to the hydrologic cycle, has been developed and quantified over the past half century. Besides the total quantities of the elements present in various reservoirs—bedrock (the lithosphere), soils, all forms of living matter (the biosphere), the oceans, the atmosphere, and fresh water—the rates of exchange and mechanisms of movement from one reservoir to another are considered in the cycle. This concept is highly relevant in developiog a frame of reference for evaluating possible environmental... 

Mass transfer can be definnd simply as the movement of any identifiable species from one spatial location to another. Tha mechanism of movement can be macroscopic as in the flow of a fluid in a pipe (convection) or in the mechanical transport of solids by a conveyor belt. In addition, the transport of a panicolar species may be the result of madom molecular motion (molecular diffusion) or randum microscopic fluid motion (eddy or turbulent diffusion) in the presence of a composition gradient within a phase. This chapter is concerned primarily with mass transfer owing to molecular or microscopic processes. 

The structure of splendipherin has been determined using restrained molecular dynamics and simulated annealing calculations. The resultant structure is currently being employed in molecular modelling calculations using the CHARMM package. The structure and mechanism of movement of splendipherin will be published together when this work is complete. 

Of course, electron microscopy rarely gives any information about the mechanism of movement. 

The biomechanics of human movement is a growing field, spanning many disciplines. As new techniques are developed and shared across these disciplines, the field will continue to grow, allowing us to peer deeper into the mechanics of movement. 

In penetration of the cuticle and epidermis, the mechanisms of movement involve a partition-diffusion process which involves three compartments ...
