The Distribution of Cotton Fiber Length
<p>By testing a fiber beard, certain cotton fiber length parameters can be obtained rapidly. This is the method used by the High Volume Instrument (HVI). This study is aimed to explore the approaches and obtain the inference of length distributions of HVI beard sam- ples in order to develop new …

Molecular Basis of Quantitative Genetics Revealed by Cloning and Analysis of 474 Genes Controlling Fiber Length in Cotton
… billion USD. However, few genes controlling fiber quality and yield traits have been cloned and characterized to date. In this study, a large number of genes controlling the upper half mean length (UHML) of fibers were cloned using a newly-developed high-throughput gene and QTL cloning system …

Inheritance of fiber length mutants of upland cotton and relationships among lint yield, fiber quality, and economic indices
… has historically been limited by relatively poor fiber quality. Prior work at Texas Tech University identified two chemically induced mutants (TTU 202 and TTU 271) that appeared to carry at least one partially dominant gene that increased fiber length. In 1998, a series of eight crosses were made …

Controlled release of GLP-1 from affinity-based protein microspheres and quantitative analysis of the role of fiber length on phagocytosis and inflammatory response by macrophages
… trends. Quantitative analysis of the role of fiber length on phagocytosis and inflammatory response by macrophages. Asbestos fibers induce chronic lung inflammation and have been associated (WHO estimate) with 105 lung cancer deaths per year worldwide. In the lung, immune cells (macrophages) …

Modeling of Microstructures and Stiffness of Injection Molded Long Glass Fiber Reinforced Thermoplastics
… of the use of injection molded discontinuous fiber-reinforced thermoplastics. During the intensive injection molding process, severe fiber breakage arises in the plasticating stage leading to a broad fiber length distribution. Fiber orientation distribution (FOD) is another highly anisotropic …

Gas holdup in a gas-liquid-fiber semi-batch bubble column
… gas holdup and flow regime in Rayon and Nylon fiber suspensions. This study determines the effect of superficial gas velocity, fiber type, fiber mass fraction, fiber length, and aeration plate open area ratio on gas holdup and flow regime transition in various fiber suspensions.;Experimental …

Nanofiber characterization of self-assembling peptides RAD16 and RID 12
… have been shown to form a network of nanofibers that can be used in scaffold research or as templates for nanowires. However, self-assembling peptides have not been widely studied and further research is needed to fully understand the properties and organization of the peptide hydrogels. …

An Evaluation of the Thermodilution Method for Measuring Ventricular Volumes.
… law relates energy of contraction to the initial length of the cardiac muscle fiber. To apply this law directly requires some measure of fiber length. The volume of the ventricular cavity is a function of this fiber length and thus can provide such a measure. For this reason many investigators …

Structure and formation of β-sheet fibers
… organization of protein monomers into fibers, bundles and networks is central to biology. Inspired by the repetitive patterns found in the amino acid sequence of natural fibrous proteins, short peptides have been designed to self-assemble in aqueous solution into gelatinous matrices. …

The Effects of Carbon Fiber Misalignment on Composite Material Strength
… isotropic composites. On the other hand, fiber misalignment measurements are taken through via digital microscopy to satisfy a statistical approach for the determination of the same elastic modulus. The Paper Physics Approach (PPA) and Laminate Analogy Approach (LAA) are utilized to …

Effect of different production practices on the development of verticillium wilt and cotton fiber quality
… damaging disease capable of reducing yield and fiber quality of cotton (Gossypium hirsutum L.). To date, aspects of integrated disease management of Verticillium wilt on cotton yield and fiber quality are not entirely understood. In addition, limited information is available regarding the …

Growth of Textured Mullite Fibers Using Polycrystalline Precursors
… and templated into polycrystalline mullite fibers by extrusion. Textured growth of mullite fibers with elongated grains, aligned along the long-axis of the fibers, was achieved by heat treatment. Repeated heat treatment cycles of a whisker-templated fiber showed a bamboo-like microstructure. …

Extension of the Method of Ellipses to Determining the Orientation of Long, Semi-flexible Fibers in Model 2- and 3-dimensional Geometries
The use of fiber-reinforced polymer composites formed via injection molding is of increasing interest due to their superior mechanical properties as compared to those of the polymer matrix alone. These mechanical properties, however, are strongly dependent on the fiber length and orientation …

Processing-Microstructure Models for Short- and Long-Fiber Thermoplastic Composites
… data strongly suggest that the majority of fiber length degradation occurs in the earlier stages of injection molding, in the screw nozzle, runners, and gate. A better understanding of the melting and flow conditions upstream of the mold cavity, the simulation of which is beyond the scope of …

Factors Affecting Fiber Orientation and Properties in Semi-Flexible Fiber Composites Including the Addition of Carbon Nanotubes
… the orientation of injection molded long fiber composites in an end-gated plaque were investigated. Matrix viscosity was found to have a small effect on fiber orientation. The impact matrix viscosity had on orientation was dependent on fiber loading. At lower fiber loadings, the higher …

Characterization of Carbon Mat Thermoplastic Composites: Flow and Mechanical Properties
… mm long, 7.2 micrometer diameter, chopped carbon fibers in a polypropylene (PP) or poly(ethylene terephthalate) (PET) thermoplastic matrix were manufactured using the wetlay technique. This produces a porous mat with the carbon fibers well dispersed and randomly oriented in a plane. CMT composites …

Characterization of self-assembling peptide nanofibers of KLD12 and RID 12
… solutions were studied with rheology. Nanofiber structure was studied through atomic force microscopy. Sonication was found to have a minimal effect on KLD12, while pH could alter the length of the fibers formed. The presence of a second type of peptide in solution interacted with …

High-order compensation of self-phase modulation in laser communication systems
Self-phase modulation (SPM) creates a power and fiber-length dependent spectral broadening that reduces signal-to-noise ratio in free-space laser communication systems which use a fiber to connect their transmitter's high-power optical amplifier to its telescope optics. The effects of SPM can be …
