In the former case the function of the telescope is simply to increase the dispersion, and the formation of the bands is of course independent of the particular manner in which the dispersion arises. The phrase "to bring again the captivity" would not alone suffice to prove this, for it is used in a wide sense, and perhaps means rather to "reverse the calamity," 4 but the dispersion of Israel among the nations, and the allotment of the Holy Land to new occupants, cannot fairly be referred to any calamity less than that of the captivity. So, you may think that Canada's population is just like England's or France's. whistler mode waves: Why is electron energy dispersion not reflected in the waves? credit by exam that is accepted by over 1,500 colleges and universities. Clumped dispersion is when individuals in a population are clustered together, creating some patches with many individuals and some patches with no individuals. To determine N recourse must be made to Cauchy's formula of dispersion (q.v. There is another coefficient of absorption (K) which occurs in Helmholtz's theory of dispersion (see Dispersion). dispersion characteristics of the speaker. 16 with the dispersion "afterwards," 18, &c.); see Canaan; Genealogy; Nimrod. - The Samoans are pure Polynesians, and according to the traditions of many Polynesian peoples Savaii was the centre of dispersion of the race over the Pacific Ocean from Hawaii to New Zealand. The population at that time was a tenth of what it is today. the mean is a poor fit of the data). The theory of anomalous dispersion has been applied in a very interesting way by W. The first attempt at a mathematical theory of dispersion was made by A. Air pollution dispersion modeling was carried out to predict ground level pollution concentrations in the boro in 2004. The type of pattern often results from the nature of the relationships within the population. Mode:The most commonly observed value in a data set Samples are randomly chosen from populations. The term is most often used when referring to a drastic decline in human population, which impacts the economy and the quality of life of individuals in the population. The structure of the dispersion was examined by small-angle synchrotron X-ray scattering on beamline 8.2. But more than this, it throws a remarkable light upon the solidarity of the Hellenic Dispersion. 20. related. Together all of these elements combine to show us exactly what a society can look like.

Only very thin layers are sufficiently transparent to show the dispersion near or within an absorption band, and a large refracting angle is not required, the dispersion usually being very considerable. The author was in all probability a Jew by race, and he would seem to have addressed himself especially to Jewish readers; but they were Jews of the Dispersion.

These glasses, however, still hold the field, although glasses are now produced whose irrationality of dispersion has been reduced to a very slight amount.

You can test out of the f a = f b = f c = f, then the relative partial dispersion (n n b) (n a - n b) must be equal for the two kinds of glass employed. — Bon Appétit, "Add Leeks to Your Latkes. Researchers often compile data on age and sex into charts, called population pyramids, that help us understand population growth. RELATED. In the late 20th century, a preference towards male offspring led to imbalanced populations in several East Asian nations. Already registered? dispersion curve thus produced is then used to calculate the material stiffness. its geographic distribution, density, growth rate. So, the question isn't what are the elements of population composition, the question is what do you want to study? Sellmeier's theory did not take account of absorption, and cannot be applied to calculate the dispersion within a broad absorption band. 3. Soleil's saccharimeter, as its name implies, is designed for the study of solutions of sugar, and it is clear that it will only work satisfactorily with active media that have nearly the same rotary dispersion as quartz. Clumped dispersion is when individuals in a population are clustered together, creating some patches with many individuals and some patches with no individuals. | Meaning, pronunciation, translations and examples Though few follow him so far, an explanation of the principle will make it clear that there are numerous possible opportunities for anomalous dispersion to qualify inferences from the spectrum. Then again, to plant down a portion of the Allied troops on one side of the Straits, while continuing operations on the other side, would mean voluntary dispersion of resources in place of concentration. In calcium, for instance, the g line shows in the laboratory much stronger anomalous dispersion than H and K; but in the solar spectrum H and K are broad out of all comparison to g.

If the refractive index for one colour be n, and for another and the powers, or reciprocals of the focal lengths, be 4) and 4)+4, then (I) d�/ 4) = dn/ (n - I) =1 /v; do is called the dispersion, and v the dispersive power of the glass. In the case of narrower lines, however, higher dispersion is required to prevent the light of the continuous spectrum on either side of the dark line from blotting out the monochromatic image. They are formed now on one side, now on the other, of the absorption line; but the rapid increase of refractive index which accompanies true anomalous dispersion, and might be expected to produce similar bands by scattering the light, appears both from theory and experiment to belong to the side of greater wave-length exclusively. Population distribution is a term that is used to describe how people are spread across a specific area. In essence, we're asking how many males and females live in a population.

To reduce the aberrations Sir David Brewster proposed to employ in the place of glass transparent minerals of high refractive index and low dispersion. He concluded that there could be no refraction without dispersion, and hence that achromatism was impossible of attainment.
