Shortly after taking part Olympics 1998, curling became one most popular winter sports TV. reflections interest society have found response world science and an increase observed scientific studies curling. However, d...
BACKGROUND The aim of this study was to determine whether toe sliding is more likely to cause knee injuries than flatfoot sliding in curling. METHODS Twelve curlers participated in the study, each delivering 12 stones. Six stones per volunteer were delivered using a flatfoot slide and six were delivered using a toe slide. The Pedar-X in-shoe pressure system recorded the plantar pressure durin...
Given a finite nonempty sequence S of integers, write it as XY k, where Y k is a power of greatest exponent that is a suffix of S: this k is the curling number of S. The curling number conjecture is that if one starts with any initial sequence S, and extends it by repeatedly appending the curling number of the current sequence, the sequence will eventually reach 1. The conjecture remains open. ...
In this study, a two-state mechanochemical model is presented to describe the dynamic instability of microtubules (MTs) in cells. The MT switches between two states, the assembly and disassembly states. In assembly state, the growth of MTs includes two processes: free GTP-tubulin binding to the tip of protofilament (PF) and conformation change of PF, during which the first tubulin unit that cur...
The early events in the alfalfa-Rhizobium meliloti symbiosis include deformation of epidermal root hairs and the approximately concurrent stimulation of cell dedifferentiation and cell division in the root inner cortex. These early steps have been studied previously by analysis of R. meliloti mutants. Bacterial strains mutated in nodABC, for example, fail to stimulate either root hair curling o...
BACKGROUND Inward curling of the barbs of Meniscus Arrows during degradation was observed in a previous study, in which swelling, distention, and water uptake by Meniscus Arrows was evaluated. This change of configuration could have consequences with respect to anchorage capacity in bone. MATERIAL/METHODS Eight non-degraded Meniscus Arrows in the original configuration were pulled out of thaw...
