BACKGROUND AND PURPOSE The gait speed that a patient selects is a well-known indicator of overall gait performance. The purpose of this study was to use multiple linear regression to assess the strength of association of temporal, kinematic, and kinetic gait variables with high walking speeds in patients with hemiplegia. SUBJECTS Thirty-two subjects (20 male, 12 female) with an average age of...

A symmetric Power Amplifier with an optimized impedance quarter wave transmission line is presented using a thermally enhanced high Power LDMOS FET i.e. a 140W Infineon PTFC261402 device. This implementation is realized in the operating frequency of LTE Band41 (2.496GHz-2.69GHz) applicable for LTE base stations. This design achieves a high efficiency that persists for an output power back off r...

vegetation is known to increase hillslope stability by reinforcing soil shear resistance. this reinforcement depends on the density and tensile strength of the root systems. this paper presents the results of research carried out in order to evaluate the biotechnical characteristics of the root system of parrotia persica. the profile trenching methods was used to obtaining root area ratio (rar)...
