Clothing affects heat and moisture loss. Increasing the thickness or number of layers of clothing increases its insulating capability and reduces body heat loss. Clothing insulation is usually described with the do unit. Originally, t do was defined as the thermal resistance necessary for comfort while sedentary in a uniform still air environment of 21 °C. In conventional SI nomenclature I do has a thermal resistance of 0.155 K m-/W. Some ensembles do values and associated comfort temperatures are shown in Fig. 5.4. 

The Relation between the Shell Model and Layers of Spherons.—In the customary nomenclature for nucleon orbitals the principal quantum number n is taken to be nr + 1, where nr> the radial quantum number, is the number of nodes in the radial wave function. (For electrons n is taken to be nT + l + 1.) The nucleon distribution function for n = 1 corresponds to a single shell (for Is a ball) about the origin. For n = 2 the wave function has a small negative value inside the nodal surface, that is, in the region where the wave function for n = 1 and the same value of l is large, and a large value in the region just beyond this surface. 

It will be useful to establish some general nomenclature before proceeding. We have already defined the terms slider and substrate within the context of the model in Figure 8. To properly impose shear and load, it will prove convenient to subdivide the system even further. Specifically, only the outermost layer of the slider will be coupled to an external driving device. We will refer to this layer as the top layer (tl). Similarly, the substrate will be constrained by fixing the center of mass of the bottom layer of atoms in the substrate. This layer will be called the bottom layer (bl). All other atoms will be referred to as the embedded system, regardless of whether they are in the slider, substrate, or fluid. 

The Schmidt number is the ratio of kinematic viscosity to molecular diffusivity. Considering liquids in general and dissolution media in particular, the values for the kinematic viscosity usually exceed those for diffusion coefficients by a factor of 103 to 104. Thus, Prandtl or Schmidt numbers of about 103 are usually obtained. Subsequently, and in contrast to the classical concept of the boundary layer, Re numbers of magnitude of about Re > 0.01 are sufficient to generate Peclet numbers greater than 1 and to justify the hydrodynamic boundary layer concept for particle-liquid dissolution systems (Re Pr = Pe). It can be shown that [(9), term 10.15, nomenclature adapted]... 

Triple-layered [2.2]metacyclophanes (tribenzaspiro[5.5]undecaphanes)9o) have been described by several groups 17,90,91 . Two interconvertible isomers 74 and 75 were isolated (cf. Ref. 17) and 90) for their nomenclature) with one (75 with C21l-symmetry) being thermodynamically more stable by approximately 16 kJ mol-1 as established... 

A chemical species on the top-most layer of the solid (i.e., a surface species) occupies a site. For example, an arsine molecule adsorbed on a surface occupies a site, and could be denoted AsH3(s). Another example of a surface species is a bare gallium atom, Ga(s), on the top layer of a gallium arsenide crystal. What happens if another species, say a gas-phase AsH3, lands on top of the Ga(s) As shown in Fig. 11.3, the gallium atom that was at the surface is buried it is no longer designated a surface species. In this nomenclature it has become a bulk species.
