Inter-element spacings

Variation of the inter element spacing and/or the reactive tuning loads of a periodic structure will result in a new resonance slightly above the unperturbed resonance and without loss, provided that no grating lobes exist. If grating lobes from the two subarrays do exist, we will experience loss at resonance. 

Fig. 24. Velocity profile for flow of water through two different regions (highlighted in Fig. 23a) of the inter-particle space within a fixed bed of spherical glass beads. The velocity profiles are measured across the inter-particle space between two packing elements. Profiles are shown for local regions associated with fast and slow fiow velocities, characterized by a local Re of 50 and 12, respectively. At low...

Extension of this methodology to porous packing elements (e.g., catalyst support pellets) is not straightforward. The challenge arises because the signal we wish to measure is associated with the liquid (water) in the bed. However, the signal intensity acquired from a specific region of water depends on its local environment, because the nuclear spin relaxation times of water in different physical environments will vary. In this system, the different environments will be (i) free water in the bulk of the inter-pellet space, (ii) water within the intra-pellet pore space, and... 

Heat pick-up from the container outer smface was performed due to natural air convection. In the model imder the cavity the inter-fuel-element space of a free-of-alloy core part was understood. The flow path between the cavity and the surrounding space was realized with assigned hydraulic resistance and cross-section. 

Ordered arrays of carbon nanotubes (CNT) on various substrates [1] seem to be one of the most promising materials of current nanotechnology. Individual tubes in such arrays are bonded by the strong Van der Waals interactions which can be affected significantly by external molecules adsorbed to the inter-nanotubes space. This leads to high value chemomechanical effect of adsorption in CNT array based nanoelectronic structures which can be used in nanosensorics for the development of chemical sensor elements with acoustic pickup [2]. 

Figure 4.7 shows the formation of dendrites in the inter-electrode space in a symmetrical lithium/PEO/lithium element the lithium accumulates, forming a cluster which grows through the electrolyte until it causes the destruction of the battery element by an internal short-circuit. 

Pharmacokinetic concentration-time curves for a drug and ifs mefabolifes are used to identify primary exposure metrics such as AUC, or which are not time-dependent unlike the sequential measurements of concentration over time. A peak plasma concentration of a drug is often associated with a PD response, especially with an adverse event. There can be large inter-individual variability in the time-to-peak concentration, and closely spaced sampling times are often critical to determining the peak plasma concentration accurately in individual patients because of differences in demographics, disease states, and food effects, if any. All these elements are clearly spelled out in the protocols written to conduct these studies. 

We now wish to extend the considerations above dealing with several different structures extending simultaneously within the same space. Thus, for example, a macromolecule attached to carbon black at one point along its length may be cross-linked to other molecules at one or more points on either or both sides of the black particle, while another may pass fairly close to the black without contacting it and be equally cross-linked at the distant points. In order to be able to develop the mathematical relationships required for the development of this theory, it is necessary to represent the state of affairs by means of a highly idealized model. However, the model proposed here is believed to contain all the elements of a uniformly filled and cross-linked elastomeric compound. The possible existence of crystallization and inter-and intra-molecular forces other than main-chain carbon to carbon links, cross links and bonds between rubber and carbon black as hypothesized earlier, is specifically neglected. 

For any data set comprising objects (e.g., sediment samples) on which a number of variables have been measured (e.g., element concentrations), an abstract composition space can be defined in which the variables are the dimensions. Within this space, the position of a sediment sample is determined by its elemental concentrations. Dissimilarity between sediment samples is measured by the Euclidean distances between them in the composition space. If all of the elements varied in concentration independently (i.e., they were uncorrelated), then the concentrations of all elements would be needed to describe the positions and inter-relationships of the samples. However, in all real sediment data sets, the element concentrations are partially interrelated sediment samples can be seen as mixtures of a small number of independent multi-element sediment components. In such a case, the composition space can be accurately represented by fewer axes (dimensions). The...
