A new theoretical model for estimating the entrained air film thickness between a web and roller is presented for both impermeable and permeable webs. A simple closed-form formula for estimating the air film thickness, which considers the effects of air leakage from the web edges and air ...
We observed no cases of three or more males on the same female web. We most commonly observed the situation of a male staying in its own web and connecting to a female's web with its silk thread (46% of cases). Of the female webs chosen by males, 68% were decorated with both an...

Although the structure of empirical food webs can differ between ecosystems, there is growing evidence of multiple ways in which they also exhibit common topological properties. To reconcile these contrasting observations, we postulate the existence of a backbone of interactions underlying all ecological ...

I-girders with circular corrugated webs are considered as a new fabrication technology. The corrugation of the web considerably increases the stiffness of the cross-section to resist shear forces and also increases the out-of-plane stiffness. However, in
known asNephila clavipes), also called the golden silk orb-weaver. The nickname “banana spider” likely comes from their often yellow coloration and elongated abdomen. These spiders build large webs, often 3-6 feet long, out of golden silk. These webs are some of the strongest of any ...
