Falls due to slips are prevalent in everyday life. The purpose of this study was to determine the reactive recovery responses used to maintain dynamic stability during an unexpected slip, establish the time course of response adaptation to repeated slip perturbations, and distinguish the proactive strategies for negotiating a slippery surface. Twelve young adults participated in the study in wh...

Inspired by ancient Near Eastern cylinder seals, we describe a method for converting images of repeating patterns, e.g., Roman friezes or Escher tessellations, into 3D-printed rollers for shaping custom-designed cookies. The rollers may be used as a math club activity to make cookies for a math event and can also be used in other creative works, e.g., imprinting ceramics and similar materials. ...

The importance of mutualism is receiving more attention in community ecology. In this study, the fire ant Solenopsis invicta was found to take advantage of the shelters constructed by the leaf roller Sylepta derogata to protect mealybugs (Phenacoccus solenopsis) against their natural enemies. This protective effect of fire ant tending on the survival of mealybugs in shelters was observed when e...

Background. Band exercise can also reduce back pain by reducing unnecessary movement of the thoracic and cervical vertebrae adjacent to the lumbar spine. Looking at previous studies, activation of the deep lumbar muscles of the lumbar spine and restoration of mobility of the adjacent skeleton have a positive effect on pain relief. Objectives. This study was to investigate the effects of self-f...

Manual lymph drainage has become the mainstay in the treatment of lymphedema for decades now. Five evolving variants have been described by Godoy & Godoy over the years: i) manual lymph drainage using rollers; ii) self-applied manual lymph drainage using rollers; iii) manual lymph drainage using the hands (manual lymphatic therapy); iv) mechanical lymphatic therapy using the RAGodoy® device; an...

Cold rolling process of a major transformation in the form of sheet metal and a wide range of steel products are produced in this way. Elastic deformation during cold rolling working rollers and the inevitable increase in the rolling force. In this study, the effect of elastic deformation during cold rolling mill rollers working on the reciprocating back and forth in tandem with the presence of...

Dung beetles belong to the superfamily Scarabaeoidea, and are mostly within the subfamilies of Scarabaeinae and Aphodiinae. They are given their name because they feed partially or exclusively on feces. Each species of dung beetles can be classified as one of several types: rollers, tunnelers and dwellers. Rollers roll the dung into round balls, which are then used for brooding chambers or as a...
