Spinning of synthetic spider silk-like fibers and ex vivo rheology of spider silk
Spider silk has been hailed as nature's super-fiber based on its mechanical properties. A synthetic analog would have numerous applications, from the textile industry to suspension cables for bridges. This thesis discusses attempts to spin a synthetic spider silk-like material (a concentrated …

Topic specific spider for taxonomic documents
… on the World Wide Web using a combination of spidering and document classification techniques. To increase the number of documents collected, two query expansion techniques have been considered and evaluated. We found that generic query expansion performed better than the taxonomically …

Fog Harvesting: Inspired by Spider Silk
… this research. This thesis topic is inspired by spider silk's ability to direct water droplets to certain locations to further enhance water collecting rate. This directional droplet movement is caused by spindle-knot and joint structure on the biomimetic silk. The spindle-knot is randomly …

Structural characterization of spider coating petide [i.e., peptide] 1 and 2 of the black widow spider, Latrodectus hesperus
<p>Spider silk is one of the most versatile material.s in nature with great mechanical properties, exceeding some of the best man made materials. Native and synthetically produced silk has been used in a wide array of applications throughout the history of mankind including nets, bandages and …

Biomimicry of the spider silk spinning apparatus
<p>Spider silk is known for its extraordinary material properties, being both very strong and extensible. Even though the fibers outperform many synthetic and natural materials, it is impractical to collect industrial amounts of silk from spiders due to their cannibalistic and venomous nature; they …

Modeling and Control of SPIDER Satellite Components
… Deployables for Engineered Reconnaissance, or SPIDER. Unlike wisps of cobweb caught in the wind, SPIDER technology will dictate the functionality and versatility of the satellite much like an arachnid weaving its own web. In the present work, a rigorous mathematical framework based on …

Fission-Fusion Dynamics in Spider Monkeys in Belize
… or most members range in close proximity, but spider monkeys (Ateles) and chimpanzees (Pan) are known for their more fluid association patterns. These species have been traditionally described as living in fission-fusion societies, because they range in subgroups of frequently changing size and …

Spider web geometry inspires long span roof trusses
… the methods and results used to learn from spider web geometries and implement them into a practical long span roof truss structure. Specifically, utilizing data and properties of spider webs found in research from Su et al. (Su I. a., 2016). The research uses and implements spider's web …

The Synthetic spider silk fibers spun from Pyriform Spidroin 2, a glue silk protein discovered in orb-weaving spider attachment discs
<p>Spider attachrnentdisc silk fibers are spun into a viscous liquid that rapidly solidifies, gluing dragline silk fibers to substrates for locomotion or web construction. Here we report the identification and artificial spinning of a novel attachment disc glue silk fibroin, Pyriform Spidroin 2 …

Head and protocerebral patterning in the spider Parasteatoda tepidariorum
Chelicerates (including spiders, scorpions, horseshoe crabs, mites and ticks) diverged from other mandibulate arthropods (insects, crustaceans, centipedes and millipedes) around 500 million years ago, making them good models to study whether traits and mechanisms of development are ancestral or …

Molecular dynamics analysis of supercontraction in spider dragline silk
Spider dragline silk is a material that has evolved over millions of years to develop finely tuned mechanical properties. It is a protein-based fiber, used as the main structural component in spider webs and as a lifeline for the spider, and it combines strength and extensibility to give it …

Indirect measures of associations and psychopathology: applications to Spider Phobia
… study was to measure fear associations towards spiders among spider phobic and non-phobic participants as well as in a group of spider enthusiasts. Results indicate that the IAT paradigm is sensitive to the strength of fear relevant associations and able to predict anxious behavior beyond the …

Fluid mechanics of bubble capture by the diving bell spider
The water spider, a unique member of its species, is used as inspiration for a bubble capture mechanism. Bubble mechanics are studied in the pursuit of a biomimetic solution for transporting air bubbles underwater. Careful experimentation is performed to understand the mechanics of bubble formation …

Imaging, Mechanics, Construction, and Sonification of Three-Dimensional Spider Webs
Spiders, silks and webs have adapted, survived, and prospered in most ecosystems for millions of years, despite being subjected to environmental and human pressures. They are the proof of an evolutionary success, in part due to the exceptional mechanical and biological properties of their silks but …
