Leafcutter ants cut trimmings from plants, carry them to their underground nests and cut them into smaller pieces before inoculating them with a fungus that serves as a primary food source for the colony. Cutting is energetically costly, so the amount of cutting is important in understanding foraging energetics. Estimates of the cutting density, metres of cutting per square metre of leaf, were ...
Kacelnikl proposes a puzzle for optimal foraging theorists, arising from experiments of Races and Nutiez2, who found that leaf-cutting ant (Acromyrmex lundi) workers changed their behavior in response to foragmg-quality information that was only known to scouts. The workers cut and transferred smaller pieces of parafilm when the scouts had been exposed to a 10% sugar solution than when they wer...
as follows. About thirteen mouths ago while on a journey, he happened to break one of the glasses of his master's lantern, and accidently trod on the pieces during the night, which resulted in a wound on the plantar aspect of the foot (the cicatrix of which he still bears) between the bases of the 1st and 2nd metatarsal bones, and a " great loss of blood." Being under the impression that he was...
This paper describes a method for solving one-dimensional cutting stock problem with usable leftover (CSPUL) in cases where the ratio between the average stock and average order length is less than 3. The proposed method can solve general CSPUL where standard stock lengths, non-standard stock lengths, or a combination of both are cut in the exact required number of pieces. The solutions of samp...
Single-wall fullerene nanotubes were converted from nearly endless, highly tangled ropes into short, open-ended pipes that behave as individual macromolecules. Raw nanotube material was purified in large batches, and the ropes were cut into 100- to 300-nanometer lengths. The resulting pieces formed a stable colloidal suspension in water with the help of surfactants. These suspensions permit a v...
the sac, which, on being opened, was found to contain about a foot of very much congested small intestines with a large piece of omentum. The stricture being divided, the hernia could not bp returned with gentle manipulation owing to the swollen condition of the contents of the Sac; the omentum was therefore ligatured with catgut in two pieces close to the neck, cut off, and the stump returned ...
