Sets of small homogeneous 18F-spheres (range 3 12 mm diameter, relevant for small lesions and lymph nodes) were suspended and covered by a 11C-silicone, which provided a scattering medium and a varying sphere-to-background ratio.
The third set was embedded in 250-mL 11C-silicone that was prepared by mixing a small volume of 11C solution into one of the silicone components using a magnetic stirrer before adding the second component, which allowed us to study the spheres at varying sphere-to-background ratios.
Under anchorage-independent culture conditions, we found that all three MPM cell lines contained a cell population that generated spheres of different sizes with varying sphere-forming efficiencies (Table 1).
In conclusion, the strong absorbed dose heterogeneity verified in this study was due to varying degree of sphere aggregation.
The method of reflections is based on an analysis of the thermal and hydrodynamic disturbances produced by a single sphere placed in an arbitrarily varying temperature field.
Concentrated sodium caseinate composites (30% w/w in water), which contained either dispersed palm fat or glass spheres varying in size and surface properties were prepared in a Brabender Do-Corder kneader.
The mean absorbed doses are given for tumour spheres varying in mass between 1 and 500 mg according to the mentioned activity and assuming the double-exponential clearance with T1/2 = 2.7 h (60%) and 150 h (40%) without tumour growth.
It consists of at least four individual filaments (right, atoms shown as spheres) with varying lateral interfilament distances (right, atoms shown as spheres, black arrows).
In addition, the model was used to observe the effect of varying sensor parameters, namely sphere size, film thickness, enzyme concentration, and mass transport of substrate and co-substrate within the sphere and film coatings, on the response of the sensors.
(D ) RMSD minimization of hard-sphere models of hexagonal close packing (HCP), cubic close packing (CCP), and body-centered cubic (BCC) packing with the nearest neighbor RuBisCO positions depicted in C. Varying the sphere diameter yields a unique minimum RMSD for each model.
