background : experts and staff of rehabilitation centers often do their activities without following the appropriate ergonomic principles and the correct methods of manual load handling. therefore, gradually and with the repetition of these activities they place themselves at risk of musculoskeletal disorders. the aim of this research is the assessment of lifting capacity by the niosh equation ...

Partially Encased Composite (PEC) column is one of the recent achievements in the field of composite columns. This paper presents a combined experimental and theoretical study on the mechanical performances of six octagonal PEC columns subjected to axial compressive and bending moment loading. The major different between them was the concrete reinforcement details. The parameters studied in the...

Dual-polarized antenna (DPA) systems can provide two independent data transmissions in line-of-sight wireless channel environments. The capacity of each data stream can be affected by a rotation angle between transmitter and receiver DPAs and channel gains of vertical and horizontal receiver antennas. In this paper, we propose a user selection scheme for the DPA system. In the proposed scheme, ...

Exploring how organizational antecedents affect potential and realized absorptive capacity, this study identifies differing effects for both components of absorptive capacity. Results indicate that organizational mechanisms associated with coordination capabilities (cross-functional interfaces, participation in decision making, and job rotation) primarily enhance a unit’s potential absorptive c...

Excessive flexion and internal rotation of the hip is a common gait abnormality among individuals with cerebral palsy. The purpose of this study was to examine the influence of hip flexion on the rotational moment arms of the hip muscles. We hypothesized that flexion of the hip would increase internal rotation moment arms and decrease external rotation moment arms of the primary hip rotators. T...

High Performance Fiber Reinforced Cementitious Composite (HPFRCC) materials exhibit strain hardening behavior with multiple cracking under tensile loading. In this paper, experimental and parametric studies are performed to assess the influence of using HPFRCC material instead of normal concrete in reinforced concrete beams. After calibrating the experimental results, the analytical results inc...
