Morphological shapes

The characterization and genesis of neoplasms on the basis of morphological (shape-related) features is needed for the evaluation of the common traits and differences among the many types of neoplasms that can affect the human body. Such identification and classification confirms that many different cell types can be involved in cancer. [Pg.201]

The investigation of the exact ECS of small particles adsorbed on a flat (monociystalhne) substrate appears to be an excellent way to determine the relative orientation dependence of y(0) and from there the relative step and step interaction energies, provided the ECS exhibits all orientations, such that the conversion to y(0) is unique [1-4]. In that sense ECS studies are an important supplement to studies of transient morphological shapes which normally yield the product of mobility x energy. [Pg.48]

It allows the obtainment of information about topography (surface features of an object, i.e., its texture and relation among these features and the material properties), morphology (shape and size of the particles and relation among... [Pg.216]

The behavior and properties of particulate material are, to a large extent, dependent on particle morphology (shape, texture etc.) size and size distribution. Therefore proper measurement, informative data presentation and correct data interpretation are fundamental to an understanding of powder handling and end-use properties. In this chapter the following questions will be addressed ... [Pg.56]

Of critical importance in the development of DPI products is the evaluation, optimization, and control of flow and dispersion (deaggregation) characteristics of the formulation. These typically consist of drug blended with a carrier (e.g., lactose). The properties of these blends are a function of the principal adhesive forces that exist between particles, including van der Waals forces, electrostatic forces, and the surface tension of adsorbed liquid layers [7], These forces are influenced by several fundamental physicochemical properties, including particle density and size distribution, particle morphology (shape, habit, surface texture), and surface composition (including adsorbed moisture) [8]. In addition,... [Pg.299]

The County of Siena coincides with the north-eastern part of southern Tuscany (Fig. 1), which in turn is defined as the part of Tuscany south of the Cecina river. This region features a varied landscape, which mirrors the complex geological history, although hilly morphological shapes prevail. [Pg.488]

Electron Microscopy Electron microscopes are instruments that use a focused beam of electrons to examine objects on a very fine scale. This examination gives information on topography (smface features and texture), morphology (shape and size of particles), composition, and crystallographic data (stmcmral arrangements). In order for the electrons to hit the sample, both the microscope column and sample chamber must be kept under vacuum. [Pg.255]

The existence of profilin II, the isoform preferentially expressed in the mammalian neuronal system, has received much attention. Like other morphogenetic cellular processes, formation and maintenance of excitatory and inhibitory synapses depend on the actin cy-toskeleton. Neurotransmitter release by vesicle exoc)4osis at the presynaptic side as well as receptor clustering and activation at the posts)maptic side both depend on microfilament networks (reviewed in Jockusch et al. 2004), and enforcement of specific synaptic connections, which are the basis for brain-specific tasks such as memory, require morphological shape... [Pg.142]

Bacteria and other prokaryotes lack the complex intracellular structures (endoplasmic reticulum, Golgi apparatus, lysosomes, mitochondria, etc.) found in plant and animal cells (eukaryotes). Bacterial morphology (shape and size) is limited to... [Pg.203]

Clearly both the electrostatic interaction 2 nd the line tension between gel and fluid phases " have been shown to dramatically affect size and morphological shapes of the domains formed. In the extreme case, arising from diffusion limited aggregation effects, even dendritic growth on pressure-jump experiments has been reported.25... [Pg.500]

Molecular clusters of different sizes were aeated by overlaying the predicted morphological shape and the optimised crystal stracture. Figure 8.6 shows the facetted molecular clusters for the a- and p-forms. [Pg.192]

The dominant mechanism of deformation depends mainly on the type and properties of the matrix polymer, but can vary also with the test temperature, the strain rate, and the morphology, shape, and size of the modifier particles (Bucknall 1977, 1997, 2000 Michler 2005 Michler and Balta-Calleja 2012 Michler and Starke 1996). Properties of the matrix determine not only the type of the local yield zones but also the critical parameters for toughening. In amorphous polymers with the dominant formation of crazes, the particle diameter, D, is of primary importance, while in some other amorphous and in semicrystalline polymers with the dominant formation of dilatational shear bands or intense shear yielding, the interparticle distance ID, i.e., the thickness of the matrix ligaments between particles, seems to be also an important parameter influencing the efficiency of toughening. This parameter can be adjusted by various combinations of modifier particle volume fraction and particle size. [Pg.1252]
