Prediction of the muscle strength by the muscle thickness and hardness using ultrasound muscle hardness meter
PURPOSES The present study investigated whether a combination of the thickness and hardness of muscles without muscle tension can be used to estimate muscle strength during knee extension in adult males and females. METHODS Seventy-two males and thirty-three females, whose ages ranged from 18 to 35 years, participated in this study. We measured muscle thickness and hardness in the right anter...
متن کاملEffect of resin thickness, and curing time on the micro-hardness of bulk-fill resin composites
BACKGROUND Bulk-fill resin composite has been introduced, their manufacturers claimed that they can be applied in bulks of 4mm, without necessitating a prolonged curing time, or a light curing unit with increased irradiance. Thus this study was conducted to evaluate the effect of resin thickness, and curing time on the micro-hardness of two bulk -fill resin composites; Tetric Evo-Ceram [TE], an...
متن کاملEffects of resin cements on hardness and thickness around titanium post: an intraradicular assessment
The purpose of this study was to evaluate hardness (indicator for polymerization) and thickness of two types of resin cement at coronal, middle and apical level of tooth root canal. Ten extracted maxillary incisors were instrumented and post space was prepared for cementation of titanium post. Samples were divided into two groups and each group was cemented either of the two types of resin ceme...
متن کاملA Comparative Study of Representation of Shore in the Works of Nima Yushij and Bahman Mohasses
In the modern art of Iran, painting discourse and poetry discourse (in spite of the ancient artistic tradition) are independent from each other. Nevertheless, poetry and painting sometimes join together; for instance, in the connection between the poetry of Nima Yushij and the painting of Bahman Mohasses. The aim of this paper is to study this connection and also find out the hidden common expe...
متن کاملCan a Shore Crab See a Star ?
1. The absolute-intensity threshold of the optokinetic response in the crab Leptograpsus variegatus was measured using a moving continuous monochromatic point source. The results are compared to the photoreceptor responses of the same animal (Doujak, 1984), to determine the photoreceptor signal for the same behavioural threshold stimuli. 2. Optokinetic eye movements demonstrate that at the peak...
