This study was to investigate the information volume of road sign and level of visibility using real road sign. Five road signs of 5and 10-letter word combinations were shown randomly to the subject for 2 to 3 seconds at 30 meters initially. The road sign was moved closer to subject, 1 meter at a time until the subject saw the road sign correctly. The distance of first correct response demonstr...

An evaluation of a low-cost, small sized solid state accelerometer is described in this paper. The sensor is intended for positioning of a mobile robot or platform. Acceleration signal outputted by the sensor is doubly integrated with time which yields the traveled distance. Bias offset drift exhibits in the acceleration signal is accumulative and the accuracy of the distance measurement deteri...

The purpose of this study was to develop a new finite element method for simulating long-term tooth movements and to compare the movement process occurring in canine retraction using a T-loop spring having large bends and with that having small bends. Orthodontic tooth movement was assumed to occur in the same manner as the initial tooth movement, which was controlled by the moment-to-force (M/...

Introduction: For some cancer survivors chemotherapy treatment is associated with lasting motor and cognitive impairments, long after treatment cessation. Cisplatin as an anti-neoplastic agent is extremely toxic and can cause severe tissue damage. In the present study, we elucidated alteration in performance of hippocampus- and cerebellum-related behaviors following acute cisplatin treatmen...

Glyphosate (N-(phosphonomethyl)glycine) is the active ingredient in a range of popular broad-spectrum herbicide formulations. Glyphosate is a chelating agent that can form stable complexes with divalent metal ions including Cu(II). Little is known about the bioavailability and ecotoxicity of glyphosate-Cu(II) complexes to aquatic organisms. In this study, we used video tracking and behavior ana...
