Morphology and Properties of Astrocytes
2010Astrocytes were identified about 150 years ago, and, for the longest time, were considered to be supporting cells in the brain providing trophic, metabolic, and structural support for neural networks. Research in the last 2 decades has uncovered many novel molecules in astrocytes and the finding that astrocytes communicate with neurons via Ca2 ...

Morphologies and Bridging Properties of Graft Copolymers
The Journal of Physical Chemistry B, 2006Morphologies and bridging properties of graft copolymers in the bulk state were studied by using a real-space algorithm of self-consistent field theory in two dimensions. The phase transition from cylindrical to lamellar phase can be triggered by changing the position of graft points and the number of branches.

Some statistical properties of mathematical morphology
IEEE Transactions on Signal Processing, 1995Analyzes the statistical properties of the basic binary and multilevel morphological operations with both 1-D and 2D structuring elements. Very simple expressions for the output distribution of erosion and opening are derived in the case of any independent identically or nonidentically distributed inputs.

Morphological and structural properties of ZnO powders
2013 10th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE), 2013Zinc oxide (ZnO) powders were prepared by the homogenous precipitation method and then calcined at 400, 600 and 800°C for 2 and 4 h. At once the powders were milled in a planetary ball milling during 2, 4 and 8 h at a constant speed of 400 rpm. The ZnO phase was analyzed from X-ray diffraction (XRD) characterization. The morphology of the particles was

The evolution of tendon — morphology and material properties
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2002Phylogenetically, tendinous tissue first appears in the invertebrate chordate Branchiostoma as myosepta. This two-dimensional array of collagen fibers is highly organized, with fibers running along two primary axes. In hagfish the first linear tendons appear and the myosepta have developed specialized regions with unidirectional fiber orientation-a ...

Morphology, mechanical properties and viability of encapsulated cells
Ultramicroscopy, 2007The morphological and mechanical properties of encapsulated yeast cells (Saccharomyces cerevisiae) have been investigated by atomic force microscopy (AFM). Single living cells have been coated through the alternate deposition of oppositely charged polyelectrolyte (PE) layers.

Morphological and Thermal Properties of Cellulose−Montmorillonite Nanocomposites
Biomacromolecules, 2008Cellulose-layered montmorillonite (MMT) nanocomposites were prepared by precipitation from N-methylmorpholine- N-oxide (NMMO)/water solutions. Two hybrid samples were obtained to investigate the influence of the reaction time on the extent of clay dispersion within the matrix. It was observed that longer contact times are needed to yield nanocomposites

Properties of multiscale morphological smoothing by poweroids
Pattern Recognition Letters, 1994Summary: The shape semi-invariance property in the morphological filtering of grey-scale functions is defined. We show that only the poweroid family of structuring functions causes the resulting filter to possess shape semi- invariance. We demonstrate a morphological separability property for paraboloids.

Morphology and Properties of Hair
2018This chapter discusses briefly the chemistry of keratin fibers needed to understand the nature of a wider spectrum of events within these fibers. Hair fibers form a major component of the outer covering for most mammals. They create a physical barrier between the animal and its environment, and have evolved as a result of their necessary exposure to ...

Membrane morphology and transport properties
Desalination, 1985Abstract By changing properly the preparation conditions, it is possible starting from the same polymer to obtain asymmetric membranes with different morphology and U.F. performances. The SEM cross-section give us information about the overall structure.
