Parts Orientation

Only applicable in rack operations, whether or not a part is allowed to cup solution and carry it away is an important factor which is sometimes open to adjustment. However, in many operations and for many parts this consideration is [Pg.215]


In the case of thicknesses larger than mentioned above the intensities must be calculated according to the more general many-beam theory. The calculation should include summation over different groups of crystals having a certain distributions of thickness and orientation. A method based on the matrix formulation of the many-beam theory was developed for partly-oriented thin films and have been successfully applied samples [2]. The main problem in using direct many-beam calculation is to find the distribution functions for size and orientation of the microcrystals. However, it is not always possible to refine these functions in the process of intensity adjustment. Additional investigation of the micro-structure by electron microscopy is very helpful in such case. [Pg.106]

Consider now the water molecules cited in the next layer. These are molecules only partly oriented by the field arising from the charged electrode, but also partly disoriented by thermal and hydrogen-bonding influences of the particles of the solution. These dipoles are able to orient themselves more, and therefore they may contribute to e, at least to that part of the dielectric constant that arises from orientation polarization. The value of ein this second hydration layer is larger than the value of 6 found in the first one. [Pg.181]

At low concentrations, surface-active additives may form a first adsorbed layer on the sol particles with the lyophobic part orientated outwards, thus sensitising the sol. At higher concentrations a second, oppositely orientated, layer would then give protection214. [Pg.240]

In 1154 Idrici prepared a map on 17 sheets and a round general map of the Earth. It is interesting to note that in its part oriented southwards, where the Russian lands located, the Black Sea was found in the upper part. [Pg.14]

This response is that of a permanent dipole that is partly oriented by a weak electrostatic field. "Weak" means that the energy put into orientation is much less than thermal energy the field gently perturbs otherwise random orientation. This response is slow x is so large that the contribution to forces from dipole orientation "counts" only in the n = 0 limit of low frequency. [Pg.222]

Again in the lubrication of moving metal parts oriented layers are produced, solidly anchored to the metal by carboxyl groups etc. Only the London interaction between the hydrocarbon tails then still acts between the two metal parts each with their layer of lubricating oil. A pure hydrocarbon (kerosene or paraffin oil) lubricates badly since this is forced away through inadequate adhesion to the metal. This is not only a consequence of too small a viscosity since a soap solution (potassium oleate etc.) is serviceable (drilling oil). [Pg.354]

When a molecule is partly oriented by dissolution in a liquid crystal solvent it is necessary to consider direct dipolar splittings, nuclear screening anisotropies, and possibly also very large quadrupolar splittings, in order to account for the spectrum. The ways in which this can affect multiple resonance experiments have been considered already. (33, 35-37, 46) In this section we discuss some applications. Naturally, proton decoupling is often used to simplify spectra of oriented molecules, although it is desirable to avoid complete decoupling of the solvent protons. [Pg.400]

If the rotating cylinder could be brought suddenly and smoothly to rest, the second term on the right would vanish, and the resulting equation would describe the process of disorientation, by free rotary diffusion, of the molecules which had previously been partly oriented by the flow. The speed of disorientation is proportional to the rotary diffusion constant, 0, and the final steady state of random distribution corresponds to the equation q = const. = Nj4 n. [Pg.146]

In addition to lipid-like molecules, polymers can also form self-assembling particulates [8]. As expected, the amphiphilic polymers do form polymeric micelles with polar part orienting towards the surface of the particle and the hydrophobic part orienting towards the core of the particle. Also, in this case, different complicated self-assembled structures can be tailored by using block copolymers with regular blocks of monomer units but, only the simpler ones have been investigated so far in the context of drug delivery. [Pg.600]

Part of this water is polarized, that is, the dipole moment is partly oriented aroimd an angle normal to the membrane surface, contributing to the surface potential. In the bilayer conformation, the low dielectric permittivity of the hydrocarbon core (s = 2) makes the membrane an electrical insulator (Montal and Mueller, 1972). The orientation of the water dipole with respect to the plane of the membrane contributes to the dipole potential (Brockman, 1994). [Pg.504]

Design for part orientation to maximize the value added in each setup. [Pg.1316]

When the dipole moment of the solute is greater in the excited state, then, although the solvent cage becomes strained, the Franck-Condon excited state is formed in an already partly oriented solvent cage, and the excited state is more solvated than the ground state. [Pg.409]

Here the ground state solvation energy results largely from dipole-dipole and ion-dipole forces, so there is an oriented solvent cage. If the solute dipole moment is increased during the transition, the Franck-Condon excited state is formed in a cage of already partly oriented... [Pg.409]

An assembly model can be considered as an advanced one when it is suitable for the description of all the information demanded by the above listed activities. The part oriented approach to the modeling of mechanical systems has been replaced by a more comprehensive and integrated approach that includes the modeling of assemblies and kinematics. In fact, assembly modeling has developed into a key position in concurrent associative modeling. [Pg.158]

Individual droplets or bubbles can also be actuated to drive assembly if parts are located on or in the droplets. Tools available for the manipulation of droplets include electrowetting, mechanical vibration, thermal capillary flow, acoustic radiation, and surface roughness modification. Parts can be transferred with the droplet along programmable paths, and the fabrication and equipment requirement is relatively simple compared to other processes. The limitation will be the part size relative to droplet size, control over part orientation, and the speed which the parts can be actuated. [Pg.1198]

Fi). 10. Stress-strain curves of polyester fibres at 65% rh, 20°C. (a) As received, after drawing which partly orients and tightens non-crystalline regions, (b) After treatment in water at 95°C under zero tension, which allows non-crystalline regions to contract and form intermolecular bonds on cooling. The rupture of these bonds gives the sigmoidal start to the stress-strain curve. [Pg.343]

Since the atom connectivities of the individual building blocks are already known from their spectroscopic characterization, the task for the supramolecular chemist is to determine the secondary structure of the noncovalent complexes formed from these building blocks. Is the binding interaction between different building blocks specific or is there some unspecific complexation observed Is the guest molecule really inside of the cavity of a capsule or does it prefer a different location, for example, does it stick to the outside Is one part really threaded through the other in a mechanically bound molecule What is the topology of such a complex How are the parts oriented relative to one another in the whole complex These are the questions to be answered. [Pg.405]
