To determine the appropriate b for these experiments, we calculated growth factors for different wavelengths and matched them to the experimental data. At laser wavelengths of the order of 1 mm, successful fast ignition requires strong anomalous laser beam-pellet coupling. The structure of this 0.5-mm mode is highly periodic, implying a much narrower spectrum of wavelengths than in single wires z pinches. The initial density profile shows a spectrum with larger amplitudes at longer wavelengths. The main aspect concerns the possibility of extending the range of applicability to other absorption edge wavelengths, that is, other elements. Moreover, the atmospheric and surface conditions necessary for such life are likely to provide only a limited spectral window of transmitted wavelengths of that light. The purple bacteria, therefore, must ' make their living ' by utilizing green light and far-red light of wavelengths above 750 nm. Specifically strong lines were found at wavelengths corresponding to energies of q x 13.6 where q = 1, 2, 3, 4, 6, 7, 8, 9, 11. A second class is transformed to a solitary-wave solution where the spectrum at short wavelengths is more rapidly damped than at long wavelengths. The perturbations were assumed to be of sufficiently short wavelengths to justify the slow time and radiusfrozen-in approximation for the unperturbed systems. Accordingly, it is of practical interest to examine the wave spectra that span from long to short wavelengths. The present study investigates this possibility, that some wavelengths are more susceptible. With the exception of the enstatite, it seems that there are few specific features at wavelengths longer than y300 nm. They also find that alignment is more pronounced for shor ter wavelengths. Although wavelengths approaching the infrared range reduce ' scattering ', they have an undesirable ' heating ' effect. The viscous mode is unstable, and it is seen that the curve of the viscous mode coincides with the thermal mode at long wavelengths. The characteristic scale length of the preplasma was a few laser wavelengths. The uncertainty in the measured wavelengths is % 0.02 nm. The wavelengths over which resonant (or near-resonant) interactions occur is found to be affected strongly by current velocity. There are two dominant wavelengths that a dichromat cannot discriminate from gray. In our sample, the distribution of optimum predicted wavelengths of peak sensitivity includes a cluster. In the present study, we seek to determine the flash sensitivity of cone-driven b-waves at different wavelengths. To maximize contrast cues from objects in a monochromatic environment, the remaining visual pigments should be matched to the ambient wavelengths of light. Data are reported as the ratio of fluorescence intensity at the two emission wavelengths. Dual excitation wavelengths were used: 490 nm and 450 nm. In addition, the different horizontal cell types can be distinguished by their responses to light stimuli of different wavelengths. As we know, the best vacuum we can form is still a seething mass of virtual particles of many different wavelengths. Table 1 shows the expected pulse width for shortening until the relaxation time before and after pulse compression at four wavelengths. The results reaffirm that bound electrons can strongly influence the index of refraction of numerous plasmas over a broad range of soft x-ray wavelengths. The wavelengths are measured as the distance traveled between two adjacent local minimums. All wavelengths and the mean water depth h are measured in m ; wave amplitudes are denoted by a and are measured in mm. The travelling microscope is used to measure the position of the spark discharges, the wavelengths, and the wave amplitudes in the earliest stage of growth. Improved classifications may result for all species tested if spectra were collected using a spectrometer that measures absorbance at wavelengths above 1700 nm. More quantitatively, the corona minimum and maximum radii and the instability wavelengths agree to within 20% throughout the first 50 ns. Then the total suite of light-emitting diodes could be wired to permit the operation of individual wavelengths, depending on the remote sensing measurement required. The reversion efficiency was found practically the same with all of the investigated wavelengths. In the cases studied, twodimensional encroachment surpassed one-dimensional run-up for wavelengths less than twice the island base diameter. Figure 1depicts island geometry and lists data for the circular islands and wavelengths investigated. Finally, we consider the development of an initial disturbance composed of two different wavelengths. In the absence of surface tension, = 0, all wavelengths are unstable. Using this method the response of the surface to different wavelengths of disturbance could be observed. The theory assumes that any changes in the wave and current properties occur over a scale of several wavelengths. Capillary-gravity waves with wavelengths close to the resonance condition have been considered only for free-surface waves. The error bars give the minimum and maximum wavelengths participating in the mean. The error bars indicate the minimum and maximum wavelengths participating in the mean. Thus, certain spatial wavelengths (and corresponding temporal frequencies) dominate the sound field. At the physical level, an object has a property called surface spectral reflectance - it reflects different percentages of the incident light at different wavelengths. Visible light has wavelengths of the order of hundreds of nanometers. The statement that we have internalized light to become visible only when its wavelengths are between 300 and 800 nm, is nonsensical. Major features in anhydrous silicate mineral spectra occur at longer wavelengths than in the water spectrum, at l>9 mm. The features at longer wavelengths are more likely to be associated with the silicate component of the matrix. Adaptive optics are assumed for the two shor ter wavelengths. As can clearly be seen, the mass spectra show that the fragmentation patterns between the isomers are different for both wavelengths and polarizations. The difference between this simulation and the other two must result from the longer wavelengths of the initial inter face per turbation. Experimental work on self-absorption of femtosecond laser pulses in copper targets at 800 nm and 400 nm wavelengths is ongoing. The rule of thumb is that one can use multiple wavelengths with respect to the one-photon excitation condition accordingly with the nth photon excitation order. No emission was observed except for the low-level blackbody filament radiation at the longer wavelengths. Large wavelengths always remain stable and may only propagate as dark-type excitations. The typical wavelengths in the y-direction are about 15 km for the dust and roughly about 7 km for the neutral gas. Here r and s are the wavelengths associated with the radiation and dust acoustic velocities, respectively. An intense short laser pulse or a millimetre wave propagating through a plasma channel may act as a wiggler for the generation of shorter wavelengths. The grid length of 4.5 mm thus includes a safety margin that allows the simulation to grow longer wavelengths if required. Such wavelengths are comparable to those observed at stagnation using a random density "seeding" method. With neutrons, the absence of instrumental scattering at low s values and the use of longer wavelengths more than compensate for the lower flux. The instability occur s at longer wavelengths as increases. The intensity of 7-hydroxycoumarin fluorescence was measured at excitation and emission wavelengths of 338 and 458 nm, respectively. Excitation and emission wavelengths were set at 358 and 428 nm, respectively. Readings were taken using all of the nine standard filters, at wavelengths ranging from 425 to 685 m/x. The diode detectors were set at wavelengths of 220, 235 and 260 nm. The wavelengths of the peaks do not move significantly from 257 nm, not even at the maximum irradiation dose. Samples prepared by mixing b-carotene with powdered gypsum, halite and epsomite were analysed using two different excitation wavelengths (514 nm and 785 nm). All the samples were analysed using two excitation wavelengths. 100 ppm of b-carotene mixed with halite inside the gypsum crystal was easily detected. At the shortest laser wavelengths, there is still some incertitude concerning the scaling vs. laser intensity. The excitation/emission wavelengths for fluorescein were 488/530 nm and for tetramethylrhodamine were 514/570 nm. In the plasma based applications, it is required that intense laser light be propagated through thousands of wavelengths of underdense plasma. The two spectrometers were centred at different wavelengths, so we could obtain information on a wider spectral region for the same laser conditions. With test flashes of shor ter wavelengths, two major ar tifacts may intrude. Optical excitation was accomplished using 340-nm and 380-nm wavelengths with an emission at 510 nm. After sulpiride injection, a sensitivity decrease was found for all wavelengths tested. Relation of spatially induced brightness changes to test and inducing wavelengths. As expected, perceived brightness is reduced at longer wavelengths where the protanopes' retinal efficiency declines. The presentation order of the wavelengths was randomized. Sensitivity was measured for wavelengths between 450 and 670 nm. However, deeper into oceanic water, the longer, redder wavelengths are attenuated, and the penetrating light is predominantly blue. Reliable spectral sensitivity functions were readily recorded from such animals for test wavelengths between 360 nm and 440 nm. The dominant wavelengths of the surface colors were measured with a spectroradiometer. Numerical generation of short wavelengths violates the validity of the equations. The ratio between the fluorescence at the appropriate wavelengths allows the genotype of the resistance allele to be determined. A larger weather system will tend to produce more wave energy at longer wavelengths, corresponding to lower frequencies. The analytic solution is u = exp(ix) and the domain contains precisely five wavelengths. Recent advances include greater emphasis on experiments at optical wavelengths, and the construction of a new radio telescope that is deliberately designed for such reconnaissance. Predictions of the numerical model are compared with experimental data and excellent agreement is found to exist between measured and predicted wavelengths and velocity profiles. Particle sizing in remote sensing, which must rely on backscattering using several wavelengths, is an importani topic in experimental meteorology. Such sensitivity to external perturbations indicates that the selectivity of the instability is weak with a large bandwidth of unstable wavelengths. Similar data taking and analysis were made for water jets of different wavelengths. Based on the results, pulsed diode lasers at optimal wavelengths can be chosen for clinically adapted equipment. The action spectrum also peaks in the blue and red wavelengths. Using equations and it is possible to calculate the amplitudes and wavelengths of the stationary waves behind the head quite easily for any intrusion. Near the origin of the mixing layer, the secondary vortices had short wavelengths. The main point to observe is the divergence of "warm" and "cold" spectral sensitivities at long wavelengths.
