Qualitative Picture

A new formulation for extending the concept of heatlines and masslines to reacting flows through use of conserved scalars has been proposed. The formulation takes into account the distinct diffusion coefficients of different species. Results have been obtained for a number of two-dimensional nonreacting and reacting free shear flows under normal and zero gravity. For nonreacting flows, total enthalpy and elemental mass fractions have been used as the transported conserved scalars. For reacting flows, mixture fractions, defined as normalized elemental mass fractions and enthalpy, have been employed. The results show this concept to be a useful tool for obtaining better insights into the global qualitative picture of scalar transport for both nonreacting and reacting flows.

Qualitative Picture

Artificial stagnant aquatic ecosystems such as reservoirs, are suitable for monitoring the succession of biocenoses because they are usually formed by rearrangement of the former current river ecosystems. The weevil assembly, as part of such a dynamic biocenose, develops following host macrophytes. In the frame of weevil fauna studies realized during 2001 and 2002 in wet habitats beside four artificial lakes in Central Serbia (Gruza, Grosnica, Sumarice and Bubanj), the aquatic adults from 13 species, divided into two families, Eryrhinidae (Tanysphyrus lemnae and Notaris scirpi) and Curculionidae (Bagous bagdatensis, B. collignensis, B. lutulentus, Pelenomus canaliculatus, P. comari, P. waltoni, Phytobius leucogaster, Rhinoncus castor, R. inconspectus, R. pericarpius and R. perpendicularis), were collected. The quantitative and qualitative picture of the studied aquatic weevil assemblies, as well as indices of similarity among them, are given and related to the dimensions and ecological characteristics of studied aquatic systems (particularly the level of eutrophication).

Qualitative Picture

The surveys of the megalithic tombs of France made by Bertrand (1864; 1875), the Sous-Commission des Monuments mégalithiques, Adrien de Mortillet (1901), and Joseph Déchelette enabled maps to be made which showed the essential features of the distribution in space of the thousands of prehistoric collective tombs in France. Déchelette listed a total of 4457 dolmens and allées couvertes: fresh regional surveys and fieldwork in the fifty years that have elapsed since the publication of the first volume of his Manuel d'archéologie préhistorique, celtique et gallo-romaine in 1908 have increased this figure to between five and a half and six thousand tombs. This quantitative increase, however, has in no way altered the qualitative picture of the distribution in space of the megalithic tombs in France, implicit in Bertrand's original essay, and explicit in the analyses of Déchelette and Adrien de Mortillet.Bertrand had emphasized that the ‘dolmens’ of France occurred mainly west of a line from Marseilles to Brussels; Adrien de Mortillet's map stressed the main axis of distribution, namely from Brittany to the Gulf of Lions, and the very large numbers of megalithic tombs that exist in the six departments of the Ardèche, Lozère, Aveyron, Gard, Hérault and Lot.

Qualitative Picture

ABSTRACTOne of the applications of high dose ion implantation is to form surface alloys or compound layers. The detailed characterization of such composite structures is of great importance. This paper tries to answer the question: how can we outline, at least, a qualitative picture from the optical properties measured by ellipsometry of high dose Al and Sb implanted silicon. Attempts are done to separate the effect of implanted impurities from the dominant disorder contribution to the measured optical properties. As the ellipsometry does not provide information enough to decide the applicability of optical models therefore methods sensitive to the structure (channeling and TEM) were applied too.

Qualitative Picture

I have already reported on the spectra of 31 radio sources [1], but since then, new observations have become available, and, in addition, I have corrected my own 38-Mc/s measurements for a nonlinearity in the response of my receiver. The qualitative picture remains the same, but from the more recent information I have found values for the spectral indices of 85 sources, and have revised some of those given previously. From the larger sample of sources now available, it is possible to suggest some relationships of sufficient interest to warrant further investigation.

The spread of flame across a liquid surface II. Steady-state conditions

Qualitative Picture

The one-dimensional spread of flame along the surface of flammable liquids confined in a parallel-sided channel has been studied and the effects of physical dimensions and initial temperature upon its rate established. When the initial temperature of the liquid is below the closed flash point, flame spread depends upon the transfer of heat to the liquid sufficient to raise its surface temperature to the flash-point value and a qualitative picture of the mechanism by which this takes place is developed. When the initial temperature is above the flash point, flame spread is dependent upon conditions in the gas phase above the liquid and these are defined.

Helium 3 ◽  
Qualitative Picture

A qualitative picture of normal 3 He is proposed, which brings together the concept of an "almost localized" liquid and the existence of ferromagnetic spin correlations. The range of these correlations is shorter than in paramagnon theory, and the spin fluctuations are never in the critical regime within our approach, even at high pressure. A lattice model is introduced, which illustrates this physical picture. We also demonstrate that a metamagnetic transition in the field-dependent magnetization is not a necessary consequence of a quasilocalized picture.
