The dynamical scattering effect, which can be described as the failure of the first Born approximation, is perhaps the most important factor that has prevented the widespread use of electron diffraction intensities for crystallographic structure determination. It would seem to be quite certain that dynamical effects will also interfere with structure analysis based upon electron microscope image data, whenever the dynamical effect seriously perturbs the diffracted wave. While it is normally taken for granted that the dynamical effect must be taken into consideration in materials science applications of electron microscopy, very little attention has been given to this problem in the biological sciences.

Dynamical Effect

We show that quantum hair can alter the relation between the temperature and the mass of a black hole. A ZN electric charge on a black hole generates an electric field that is non-perturbative in ħ. A ZN magnetic charge on a black hole can be described classically, and can support a stable remnant. For global quantum hair, in contrast to gauge hair, we find no dynamical effects.

AbstractThe Poynting-Robertson (P-R) effect (Robertson, 1937, Wyatt and Whipple, 1950), assisted by a pseudo P-R effect due to the sputtering (Whipple, 1955, 1967), is known to cause small dust particles in interplanetary space to spiral toward the sun. Evaporation from the surface of such particles thus increases progressively with time and their size is being reduced accordingly. When the rate of evaporation is no longer negligibly low, it induces on the particle a measurable dynamical effect, which is associated with the implied variations in the magnitude of solar radiation pressure relative to solar attraction. By gradually reducing solar attraction, the particle evaporation tends to increase the orbit dimensions, thus acting against P-R. The P-R inward spiraling, far exceeding the dynamical effect from evaporation at larger heliocentric distances, slows gradually down as the particle approaches the sun, and virtually ceases when the critical distance is reached, where the two forces approximately balance each other. Then, typically, the perihelion distance stabilizes, while the eccentricity starts increasing very rapidly until the particle is swept out of the solar system. This, in brief, is the orbital evolution of a vaporizing particle in the absence of other potentially important but rather poorly known processes, such as particle collisions, rotational bursting, electric charging and interactions with the solar wind and with the interplanetary magnetic field.

Many researchers examined the static drapeability of textiles, they found that the textiles with different materials, structures or finishing have different drape characteristic. They analyzed also apart the static measuring the drapeability influenced with dynamical effect. They measured the dynamic drapeability during rotating the textile sample [1]. They found that the form of the draped sample is change from the dynamic effect. The Sylvie 3D Drape Tester developed at BUTE record all the surface of draped textiles with scanning technology, and the evaluating computer system define the usual drapeability parameters, like node number and drape coefficient. We complete the equipment with a tool with which we can examine the drapeability after different exactly defined dynamic effect.

Of the various names, such as “useful effect,” “dynamical effect,” “efficiency,” “ work done,” “labouring force,” “work,” which have been given to that operation of force in machinery which consists in the union of a continued pressure with a continued motion, the au­thor gives the preference to the term work , as being that which con­veys, under its most intelligible form, this idea of the operation of force, and as being the literal translation of the word “travail,” which among French writers on mechanics has taken the place of every other. The single unit, in terms of which this operation of force is with us measured, viz. the work of overcoming a pressure of one pound through one foot, he considers to be distinguished sufficiently, and expressed concisely enough, by the term unit of work , rejecting as unnecessary, and as less likely to pass into general use, the terms “dynamical unit,” and “dynam,” which it has been proposed to apply to it.
