We developed an adequate method for the in vivo analysis of organelle dynamics in the gravity-perceptive cell (endodermis) of the Arabidopsis thaliana inflorescence stem, revealing behavior of amyloplasts and vacuolar membranes in those cells. Amyloplasts in the endodermis showed saltatory movements even before gravistimulation by reorientation, and these movements were confirmed as microfilame...

there is no doubt that augmented feedback has an important role in improvinglearning. however, it is the content of the feedback which is challenging. the aimof the present study was to examine the effect of feedback on successful versusunsuccessful trials on simple and complex tracking tasks. for this purpose, 48undergraduate right-handed male and female students of hakim sabzevari teachertrai...

BACKGROUND AND OBJECTIVE: Premature loss of mandibular first molar is a common problem in adults. Mesial tipping of second molar may occur in this situation. Various orthodontic mechanics have been proposed for molar uprighting. The aim of this study was to compare four methods of molar uprighting using Finite Element Analysis(FEM). METHODS: In first model of this finite element study, a 0.019...
