BACKGROUND Gradual increases in mass such as during pregnancy are associated with changes in gait at natural velocities. The purpose of this study was to examine how added mass at natural and imposed slow walking velocities would affect gait parameters. METHODS Eighteen adult females walked at two velocities (natural and 25 % slower than their natural pace) under four mass conditions (initial...

0 1 5 Frequency [GHz] 6 2 3 4 Abstract The validity of lumped element microwave class-F amplifier circuit design has been demonstrated experimentally. By means of the proposed class-F amplifier design method, more than 4th-order higher harmonic frequencies can be taken into account in class-F microwave amplifier design using only lumped element components. In this approach, miniaturization of c...

The emerging service-dominant logic requires cooperation between several partners in a value-added network or value chain. Information asymmetry and information gaps may lead to uncovered and unused knowledge. This paper addresses how this problem can be solved by suggesting an approach based on contingency theory. The core idea consists of supporting and improving value-added partnerships by e...

In conventional power plants trash-racks are provided at the intakes to protect the turbines. In pumped storage plants, the draft tube or tailrace must also have trash-racks to protect the units while pumping. Because the loads believed to cause many failures of trash-racks are dynamic in nature, it is important to understand the dynamic characteristics of trash-rack structures in general and a...
