Two squeeze rolls press the seam together, while two electrode rolls or sliding contacts feed the electric power to the seam for resistance heating and welding.

Some exposures, such as animal contact, were analyzed both by category ("contact/no contact") and by comparison of the risk for light contact (only feeding from the hand or bottle feeding) with more intense contact (cuddling, stroking, or kissing).
Direct contact steam condensation used in steam jet injectors, and direct contact feed water heaters, has been studied using CFD simulations.
"Some birds duet and communicate with one another, presumably to keep in contact while feeding, but mockingbirds don't seem to do that," Dr. Cracraft said.
Yet the master stroke, music and marketing executives say, was the personal touch that Mr. Timberlake brought to every aspect of the campaign, giving his fans the impression of direct contact and feeding them a steady stream of topics to amplify through social media.
The entomotoxic effects of SiO2 NPs were explored by surface contact and feeding bioassay methods.
The entomotoxic effects of SiO2 nanostructures against S. littoralis are investigated by applying surface contact and feeding bioassay methods.
In this study, we have focused on surface contact and feeding bioassay methods to evaluate the entomotoxic effect of SiO2 nanostructures against S. littoralis.
Potent entomotoxic effects of silica nanostructures were explored against cotton leaf worm (Spodoptera littoralis) for the first time by utilizing surface contact and feeding bioassay protocols.
