Abstract The effect of the solid–wall boundary condition on the segregation behavior of a sand ternary mixture differing in size but having the same proportion has been investigated in a gas–solid bubbling fluidized bed. A multi-fluid computational fluid dynamics model incorporating the kinetic theory of granular flow has been used. The mass fraction profiles of the different-sized partic...

N two other papers in this series (GERSTEL 1956; GERSTEL and PHILLIPS in prep.) I the segregation of artificial hexaploid combinations was described. These had been obtained by crossing tetraploid New World cottons with diploid Wild American species and subsequent doubling of the chromosome number. For certain characters these hexaploids were of duplex genotype (i.e. of the type ZZzz). Segregat...

A comprehensive mathematical model based on the discrete particle model and computational fluid dynamics was utilized to investigate mixing and segregation of particles in fluidized beds at high pressure. To quantify the extent of mixing in the bed, the Lacey mixing index was used. Simulations were carried out with different mass fractions of small particles at various pressures ranging from 1 ...

Minute plethodontid salamanders, genus Thorius, are far more diverse taxonomically than has been recognized previously. Populations of these salamanders from the Mexican states of Veracruz and Puebla are assigned to 10 species, five of which are described as new. Combinations of morphological and allozymic characters are used to sort the species and to make initial assessments of relationships....

The monophyletic origin of the ascomycete family Physciaceae, its position within the Lecanorales and the phylogenetic structure within the family were investigated using nuclear rDNA sequence analyses. The common origin of the Caliciaceae and Physciaceae as previously shown (Wedin et al 2000) was confirmed. Further it could be shown that the Caliciaceae are nested within the Physciaceae. A uni...

nity of an offspring. Let nothing of the kind be done. If T represents the dominant character Tall, d should represent the recessive character dwarf. For exactly the same reason if Y represents the dominant character Yellow, g should represent the recessive character green. There is no particular merit in being cryptic and using a code when plain language will do and in fact do better. Decoding...

HE segregation of continuous F, distributions has been demonstrated on the character cotyledon size in Part I “Monohybrid segregation” in WEBER (1959). The same methods were applied to the character primary leaf size for the parents and the F,, the single measurements length (insertion to tip) = x4 and area = x5 being used. Figure 1 shows the average sizes of hypocotyl, cotyledon and primary le...

This article aimed to highlight how polemic between Muslims and Christians on halal tourism is discussed in Indonesia. The study concerned three research questions: How do view tourism? Is the a term that has potential build segregation according Christians’ perspective? respond By reviewing related literature conducting interviews analysis using reception theory, this reached following conclus...
