Formal and informal modifications to the US-Japan Alliance have expanded value operational structure delivers in support of US Japanese national combined naval activities Southeast Asia. This article analyzes how now serves as an increasingly powerful force multiplier which magnifies capabilities, efficiency, impact two allies’ Unlike previous studies on role United States or Japan region, it f...

in the current study the effect of casimir force and squeezed film damping on the pull-in instability and dynamic behavior of electrostatically actuated nano and micro electromechanical systems is investigated separately. linear elastic membrane theory is used to model the static and dynamic behavior of system for strip, annular and disk geometries. squeezed film damping effect is modeled using...

this study was carried out to determine some mechanical properties of barley seed including deformation, rapture force, rapture energy and toughness as a function of moisture content (10.5%, 12.5%, 14.5% , 16.5%, db), loading rate (5, 15, 25, 35 mm.min-1) and grain size (small, medium, large). tests were performed at 7 replications by the means of a factorial base plot experiment. the results s...

in this research, softening and ratcheting behaviors of ck20 alloy steel cylindrical shells were studied under displacement-control and force-control cyclic axial loading and the behavior of hysteresis curves of specimens was also investigated. experimental tests were performed by a servo-hydraulic instron 8802 machine. the mechanical properties of specimens were determined according to astm e8...

background: elastomeric chains are commonly used in orthodontics. force decay in these materials poses clinical problems. the aim of this study was to evaluate the effects of three different mouthwashes on the force decay of orthodontic chains. materials and methods: in this experimental study, elastomeric chains with two different confi gurations were divided into eight groups (two control and...
