Aerial density

By placing diblocks or random copolymers of aerial density X, at incompatible interfaces (Fig. 16), following the work of Creton, Brown and Kramer et al. [59,60,81-83], the percolation model predicts that XL...

A new method of forming Ge nanocrystals in Si02 based on molecular-beam epitaxy combined with rapid-thermal processing is presented. We demonstrate that the method allows the formation of a high aerial density ( 5xl0 dots/cm ) of small spherical dots ( 4nm in diameter) of a narrow size distribution located at a controlled and well-defined distance from the Si/Si02 interface, and that these dots show a significant memory effect. 

The mean size and density of the dots are measured under the same imaging conditions but on plan view specimen. An example of such plan-view TEM micrographs of a sample processed under optimized conditions is shown in Fig. 6. The dot size is around an average value which for this particular case is found to be 4.5 1.8 nm. A typical value of the aerial density is 5xl0 cm. ... 

A fabrication technique based on MBE in conjunction with optimized RTF has been demonstrated, which is capable of producing a layer of crystalline Ge-nanodots in Si02 of a high aerial density, uniform size distribution, and of a well defined distance from the Si/Si02 interface. A significant memory effect was manifested by the hysteresis in the high-frequency C-V measurements for samples produced under optimized conditions. 

The only new raw material in this study was the 3-D woven fabric. In this study, 3-D E-glass woven fabric from Parabeam-Netherlands (thickness of 12.7 mm, aerial density of 1.6kg/m, and compressive yield strength of 3.7 MPa) was used. The schematic fabric architecture and detailed fiber woven after impact damage are shown in Figure 6.54. 

Pattanayak [56] explored the relationship between various drape parameters and fabric mechanical properties using an artificial neural network technique. These various drape parameters are drape coefficient (DC), drape distanee ratio (DDR), fold depth index (FDI), amplitude and number of nodes (N). He used the fabric mechanical properties determined from KES as the input parameters where as the five drape parameters are used as the output. For this study sixty five cotton fabric samples are used with a speetrum of weave structures with a wide range of aerial densities. 

The characteristics of fluid flow and related mass transfer phenomena in the web forming systems have been simulated and compared, with the emphasis on the imiform distribution of fibers in the duct and mould chamber. The model was evaluated by comparing the actual fabric aerial density distributions of the three-dimensional nonwoven products. It was foimd that the vertically oriented web forming system significantly improved the imiformity of air velocities and fiber concentration around the moulds compared to the horizontal system. Also the experimental results for the aerial density distributions of the nonwoven products followed similar airflow pattern and fiber distribution obtained by the CFD model simulation. 

Due to its density, GA concentrates in lower ground surface elevations, the basements of buildings, and within utility conduits and sewer lines. GA is a liquid that was originally designed to be delivered by artillery munitions or aerial spray.1... 

The population distribution is often defined as population density. Sources of population data for an area are census reports, detailed maps, aerial photographs, and site inspections. Special attention must be made to various... 

Its props are cast density 1.62, Trauzl value 440cc, deton vel 6600m/sec and brisance 21mm, but the 50/50 formulation, being stronger, was used for loading aerial bombs and antitank shells (Ref 31, p 265)... 

In the United States a mixture of 60% cyclonite and 40% TNT was used under the name of Cyclitol as a filling for aerial bombs. The density of the cast explosive was 1.65-1.70, its rate of detonation 7800 m/sec, and in the ballistic pendulum it gave a value of 130 (100 for TNT). In the United States this mixture is considered to be only a little more sensitive to impact than TNT with a stability similar to that of cyclonite. This does not agree with T. Urbanski s [5] investigations according to which the sensitiveness to impact of such a mixture, in a powdered form, and its ignition temperature (225°C) approximate to the corresponding values for tetryl. 

Land Subsurface Burst. Everything which was said above about land surface burst applies exactly to the aerial cloud particle population produced by a land subsurface burst in which an aboveground fireball appears. However, a third component of the particle population is found. This component appears to result from soil material which interacted with the fireball at high temperature but which was separated from the fireball early, before the temperature had fallen below the melting point of the soil materials. The particles in this component have diameters ranging from tens of microns to several centimeters and have densities which are apt to be quite low compared with those of the original soil components. The relative abundance of radionuclides in this component is quite constant from sample to sample and is independent of particle size. If we indicate by subscript 1 this third component and by 2,3 the aerial cloud components, radionuclide partitioning can be described by a series of equations of the forms... 

Previous tests of the aerial application of synthetic sex attractant of the spruce budworm resulted in reductions of up to 90% of males captured in traps baited with virgin females and/or synthetic pheromone. However, there has been no convincing demonstration of reduction in population density in the subsequent generation (33). 

An important parameter used in studies on the degree of contamination of a crop by aerial deposition is the interception fraction (p), a dimensionless measure of the proportion of the total ground deposit initially intercepted by plants. Chamberlain (1970) determined that p is critically dependent both on the density of the intercepting herbage and an absorption coefficient which he formalised as an empirical equation, as follows ...
