Main description

Equipment commonly employed for the diying of sohds is described both in this subsection in Sec. 12, where indirect heat transfer devices are discussed, and in Sec. 17 where fluidized beds are covered. Diyer control is discussed in Sec. 8. Excluding fluid beds this subsection contains mainly descriptions of direct-heat-transfer equipment. It also includes some indirect units e.g., vacuum diyers, furnaces, steam-tube diyers, and rotaiy calciners. [Pg.1174]

The mobility is one of the more significant and readily measurable properties of the electron in a medium. Since it is sensitive to the energy and the state of the electron, a detailed study of mobility can be used as a tool for their evaluation. Knowledge of mobility can be applied to dosimeters and ionization chambers togther with a measurement of induced conductivity and free-ion yield (see Eq. 10.2). The subject of electron mobility is vast. In this chapter, we will limit ourselves to electron mobility in liquid hydrocarbons with occasional reference to other liquids. Also, the treatment will be mainly descriptive. The subject matter has been reviewed by Munoz (1991). [Pg.318]

In the early days of stable ion chemistry, the experimental measurements of parameters such as NMR chemical shifts and IR frequencies were mainly descriptive, with the structures of the carbocations being inferred from such measurements. While in cases such as the tert-butyl cation there could be no doubt of the namre of the intermediate, in many cases, such as the 2-butyl cation and the nonclassical ions, ambiguity existed. A major advance in reliably resolving such uncertainties... [Pg.6]

Because of the complications involved, this aspect of rheology is still in many respects a mainly descriptive science. However, in recent... [Pg.244]

Crombeen et al [382] and Bartha et al. [381] have suggested that the concentration of pairing ions in the stationary phase be used as the main descriptive parameter in I PC. However, this parameter is not very convenient in practice, because the distribution isotherms need to be known. [Pg.97]

Thus far we have approached MO theory from a mainly descriptive point of view. 1 o begin a more quantitative treatment, recall the LCAO approximation to the Hj ground state, Eq (11.4), which can be written... [Pg.88]

It is our purpose in this paper to place emphasis on those experiments in the course of which both solid and reactants are irradiated at the same time. The experimental part is only devoted to these works. To this end we give, mainly, descriptions of experiments carried out in our laboratories. Results by other authors are considered as well, but no systematic survey has been made of all the studies concerned with this problem. [Pg.56]

The subject of statistical mechanics is a branch of mechanics which has been found very useful in the discussion of the properties of complicated systems, such as a gas. In the following sections we shall give a brief discussion of the fundamental theorem of statistical quantum mechanics (Sec. 49a), its application to a simple system (Sec. 496), the Boltzmann distribution law (Sec. 49c), Fermi-Dirac and Bose-Einstein statistics (Sec. 49d), the rotational and vibrational energy of molecules (Sec. 49e), and the dielectric constant of a diatomic dipole gas (Sec. 49/). The discussion in these sections is mainly descriptive and elementary we have made no effort to carry through the difficult derivations or to enter into the refined arguments needed in a... [Pg.395]

The present chapter deals with frictional behavior when lubricated surfaces rub against each other. In Chapter 7 attention was called to the distinction between viscous loss in a fluid film separating two solid surfaces and the friction of the surfaces rubbing directly against one another. In this chapter we shall discuss the type of lubrication in which the rubbing surfaces that carry the lubricant participate intrinsically in the lubrication process rather than merely as the geometric boundaries of the fluid film. The treatment of lubricated friction here will be mainly descriptive detailed analysis and discussion of theoretical models for lubricated frictional rubbing is reserved for subsequent chapters. [Pg.178]

The initial observations by Enders (1954) and his collaborators that virus-cell interaction culminates in the destruction of the infected cells in culture made it possible to study these alterations at both the morphological and biochemical levels. Highly cytocidal viruses, during the process of either productive or abortive virus replication, ultimately kill the cell. Notable examples of this type of viruses are the picornaviruses, the rhabdoviruses, the herpesviruses, and the poxviruses. Early studies of virus cytopathology were mainly descriptive in nature, documenting the various types of virus-induced morphological alterations to cells. With the advent of new biochemical techniques, it became possible to scrutinize the mechanisms by which these viruses altered the infected cells. The main objective of these studies has been to define the initial step of virus-induced alteration... [Pg.391]
