Figure 3 shows the TEM images of the specimens after heat treatment at 500 ��C for 2 h. All the specimens showed bright contours in the centers of spheres, which indicated the hollow morphology. The selected area electron diffraction patterns selleck chem of hollow spheres were indexed as cubic In2O3 phases. The thicknesses of shells depended on the additives, which ranged from 50 nm to 200 nm.Figure 3.TEM images and selected area electron diffraction patterns of In2O3, Sb-In2O3, Cu-In2O3, Nb-In2O3, Pd-In2O3 and Ni-In2O3 hollow spheres after heat treatment at 500 ��C for 2 h.The In2O3, Nb-In2O3, Ni-In2O3, Pd-In2O3 and Sb-In2O3 specimens after heat treatment at 500 ��C for 2 h w
Gait analysis is important for objective assessment of the effects of rehabilitation interventions.
The most accurate systems for gait analysis are camera-based systems with reflective markers [1]. These systems acquire spatial movement (3D) of many markers positioned on the body, while a software outputs the joint angles and/or other gait parameters. However, camera-based systems require a dedicated laboratory and limit the length of the analyzed walking distances. Gait laboratories also use force platforms to measure the ground reaction forces which typically record from only one or two steps in the middle of the gait sequence. The platforms are 60 �� 60 cm, so that aiming for the platforms hinders the subjects�� natural gait patterns. The alternative to camera-based systems are ultrasound systems [2] and magnetic tracking systems [3], which allow complete 3D kinematic analysis of human movements.
Over the last decade, many gait analysis systems using non-traditional methods have been developed. These systems, for example, use laser technology or measure near-body air flow [4,5] in order to estimate kinematics and spatial gait parameters. Also, electronic carpets or wearable force sensors are used for estimation of ground reaction forces, centre of pressure, and temporal gait parameters [6,7]. Since there is often a need for gait recording in various environments, portable body-mounted systems are preferred [8,9].Portable body-mounted systems allow data acquisition from many steps. The portable systems for kinematics data acquisition directly measure joint angles, or they can record accelerations or angular velocities of the body segments that carry the sensors.
Measurement of Drug_discovery joint angles Temsirolimus mechanism can be done with various electrogoniometers [9�C11]. Particularly convenient are flexible goniometers, which measure the relative angle between two small blocks that are fixed to the body segments (e.g., Biometrics flexible Penny & Giles sensors). The advantages of flexible goniometers are: their output is directly proportional to the angle and their mounting is simpler compared to some other measurement systems. However, they are not sufficiently robust for daily clinical usage.
