Rheological and morphological characterization of hierarchically nanostructured materials
… challenge. The development of novel quantitative characterization techniques is important to connect the underlying morphology to relevant processing parameters and macroscopic behavior. Rheological and morphological analysis can illustrate these governing structure-property relationships for …

Morphological characterization of medium spiny neuron development in vitro
… limited to in vivo manipulations in adults or characterization of global knockout of specific molecules. Research into MSN dendritic spine development and plasticity mechanisms were likely limited by the absence of an in vitro primary neuronal culture system that produced MSNs with mature in …

Structural and morphological characterization of model elastomeric ion containing polymers
… without a major loss of properties. A detailed morphological investigation of methacrylate based block ionomers was conducted. The effect of ionic block length, the architecture of the segments, and variations in the polarity of the glassy segments were investigated. Though the diblock materials …

Multicomponent network and linear polymer systems: thermal and morphological characterization
… blends, have been studied with regard to their morphological and thermal properties. Both systems take the advantage of not only the physical interactions between the components involved but also their themooxidative properties, giving rise to novel properties that have both fundamental and …

Optical low coherence reflectometery for morphological characterization of static and dynamic systems
… Optical Low Coherence Reflectometery (OLCR) for morphological characterization of static and dynamic scattering systems.OLCR is a white-light interferometric technique, developed in the mid-1980s to measure the amplitude and the signal loss due to discrete reflections within sophisticated optical …

Structural and morphological characterization of hydrozincite and its interaction with organic molecules
The morphological diversity and complexity of naturally occurring forms and patterns have been a motivation for humans to copy and adopt ideas from Nature to achieve functional, aesthetic and social value. Common biogenic materials, such as biominerals, constructed with mineral phases and an …

Budding yeast cell cycle analysis and morphological characterization by automated image analysis
Budding yeast Saccharomyces cerevisiae is a standard model system for analyzing cellular response as it is related to the cell cycle. The analysis of yeast cell cycle is typically done visually or by using flow cytometry. The first of these methods is slow, while the second offers a limited amount …

Morphological Characterization and Analysis of Ion-Containing Polymers Using Small Angle X-ray Scattering
… to manipulate scattering data to obtain desired morphological information. At room temperature, only the crystalline peak was found for Na⁺-form Nafion, while for Cs⁺-form Nafion only the ionic peak was observed. The utilization of one dimensional correlation function on different counterion …

Biomechanical and morphological characterization of common iliac vein remodeling: Effects of venous reflux and hypertension
The passive properties of the venous wall are important in the development of venous pathology. Increase in venous pressure due to retrograde flow (reflux) and obstruction of venous flow by intrinsic and extrinsic means are the two possible mechanisms for venous hypertension. Reflux is the …

Morphological characterization of the tobacco cyst nematode complex, Globodera tabacum sspp. tabacum, virginiae, and solanacearum (Nemata: Heteroderinae)
A morphological and morphometrical study was made of the tobacco cyst nematode complex, Globodera tabacum sspp. tabacum (GTT), virginiae (GTV), and solanacearum (GTS) including observations of eggs, second-stage juveniles (J2), males, females, and cysts. Observations focused on the anterior region …

Detection of viable urediniospores, morphological characterization in resistant and susceptible genotypes, and germ tube anastomosis of Phakopsora pachyrhizi
Soybean rust, caused by Phakopsora pachyrhizi, is a major foliar disease of soybean affecting soybean yields in many soybean-growing areas throughout the world. After the reports of its first occurrence in Brazil in 2001 and the continental United States of America in 2004, research on the disease …
