Sources that elicit a taxis response, which may cause a modification of speed, direction, or both, seem to encompass the entire range of environmental stimuli, such as gravity (geotaxis), temperature (thermotaxis), light (phototaxis), or chemicals (chemotaxis).
Variation of the plasma density causes a modification of the reflection coefficient of VLF waves from the ionosphere R, and its rate of decay in the magnetospheric resonator.
Raman spectroscopy of similar mixtures has shown that ion irradiation causes a modification of the structure of the samples which evolve towards an amorphous carbon.
Transmission electron microscopy phase-contrast images taken by amorphous carbon film-based phase plates are affected by the scattering of electrons within the carbon film causing a modification of the image-wave function.
Physical approaches may therefore ultimately be appropriate for seizure prophylaxis by causing a modification of the underlying substrate, presumably with a reduction in the intrinsic excitability of cerebral structures, or for seizure termination, by interfering with the spontaneous discharge of pathological neuronal networks.
Non-synonymous SNPs cause a modification of protein sequences that can be benign or deleterious and possibly experience selection.
These new mutations could cause a modification of the mutational landscape and reveal new pairs of SL, of course only in the treated patient sets.
In the presence of pesticides and/or heavy metals, the linkage between the toxic compound and the subunit D1 of PSII causes a modification of the signal (Fig. 9) (Giardi et al., 2008, 2009).
Probably, ethanol causes a modification of the net charge of the system and confers it some degree of steric stabilization that may finally lead to a decrease in the mean particle size [ 43].
Their application, however, can cause a modification of the gas bubble distribution in liquid, resulting in the alteration of volume fraction of gas phase and density of the system.
