Evaluation of Fish Scale Chemistry for Determining Habitat Associations
… is the first work examining the utility of scale chemistry for determining natal origins and habitat associations. I quantified a relationship of scale chemistry to water chemistry, quantified geographic variation in scale chemistry, and evaluated stability of scale chemistry through …

Applications of fish scale analysis to understand growth dynamics of fish populations
… to derive ecological information about fish populations is a fundamental tool in fisheries assessment, specifically the back-calculation of fish lengths. This study highlights the potential errors associated with correction factors (c) because of poor sampling and provides a validation …

Finite element analysis of shear resistant mechanisms for biolaminate interfaces
… dermal armor consisting of overlapping ganoid scales. Each scale is a bilayer hydroxyapatite and collagen-based bio-laminate for protection against predation. The exoskeleton fish scale is comprised of a stiff outer ganoine layer, a characteristic "sawtooth" pattern at the interface and a …

An assessment of the use of nuclear microprobe techniques in pollution studies : quantification of elemental concentrations in fish scales
… the extent of water pollution by analyzing scales of fish that live in polluted waters. As a fish grows, ions from its immediate environment are incorporated into the matrix of the fish scale and so scales can be used as biomarkers of pollution events.

Design of flexible puncture resistant gloves inspired by natural dermal armors
… the puncture resistance and flexibility of fish scale structures. Elasmoid fish scales possess a unique balance of stiffness, strength and low weight to provide protection against predators and not interfere with locomotion. In this investigation the biological design of fish scales is …

Tissue spectroscopic characterization based on fluorescence, second harmonic generation, and reflected light
… been demonstrated in the imaging of black tetra fish scale and in ex vivo human skin. Third, interferometric second harmonic microscopy has the potential for imaging deeper second harmonic active structures in tissues.

The geology of kimberlites from the Fort a la Corne area, Saskatchewan, Canada
… Mining Corporation, sponsors of the Operation Fish Scale project, which included kimberlite research at the University of Leeds. The regional setting and geological description of six kimberlite borehole intersections are presented. In addition, the broad geodynamic conditions and the …

Heterogeneous Distribution and Corresponding Mechanical Significance of The Mineral Phase in Fish Scales
Fish scales can be considered as a laminated composite based on collagen fibrils arranged in a cross-plywood structure. This collagen-based composite is often partially mineralized (primarily hydroxyapatite) in the scale exterior in order to resist penetration and hence to enhance protection. …

Optimization of heterogeneous bio-based catalysts and synthesis of inorganic equivalent for large-scale biodiesel production
… for waste resources, waste eggshells, cow bones, fish scales and banana peels were investigated, characterized and optimized to manufacture high performing Lewis base catalysts to obtain high biodiesel yield in a transesterification reaction. Initially eggshell, fish scale and cow bone catalysts …

Bulk Ceramic-Based Biologically Inspired Composites: Design, Fabrication and Testing
… materials, by aggregating various multiscale toughening mechanisms. In challenging habitats, organisms evolve to produce remarkable multifunctional material systems that improve their "fit" and "survivability". Unlike traditional materials, natural materials employ special arrangements …
