the routine treatment for rotated maxillary incisor is a fi xed appliance, but in some instance the use of this method is impossible. in addition, in only limited cases of rotation, removable appliance is applicable. in this study, the use of a semi-removable appliance is presented, which has some benefi ts over the other methods. in this study, the corrections of about 70 -90° rotation of the ...

background: left ventricular (lv) twist is due to oppositely directed apical and basal rotation and has been proposed as a sensitive marker of lv function. we sought to assess the impact of chronic pure mitral regurgitation (mr) on the torsional mechanics of the left human ventricle using tissue doppler imaging. methods: nineteen severe mr patients with a normal lv ejection fraction and 16 non-...

We determine the period, p = 11.52± 0.14 h, and a light curve peak-to-peak amplitude, a = 0.029 ± 0.003 magnitudes, of the Neptunian irregular satellite Nereid. If the light curve variation is due to albedo variations across the surface, rather than solely to the shape of Nereid variations, the rotation period would be a factor of two shorter. In either case, such a rotation period and light cu...

Purpose-grown trees have the potential to be a significant portion of the bioenergy solution in the Southeastern United States. Trees are a biomass source with existing end-use markets and associated infrastructure and provide a “living inventory” with a variety of benefits over annually harvested energy crops. The economic feasibility of utilizing tree woody biomass is improved by increasing p...
