This article introduces an innovative system for enhancing the seismic performance of a structure through facilitating large rotational (rocking) motion to occur without risking overturning. The innovation this study is in use tendons consisting Nickel-Titanium (superelastic) alloy connected series with steel impose partial restraints when experiencing rocking motion. Importantly, fully recover...

the track stiffness experienced by a train will vary along the track. sometimes the stiffness variation may be very large within a short distance. one example is when an unsupported sleeper is hanging in the rail. track stiffness is then, locally at that sleeper, very low. at insulated joints the bending stiffness of the rail has a discontinuity implying a discontinuity also of the track stiffn...

itotic spindle positioning involves a con-formational switch in LGN, the mammalian version of the invertebrate Pins protein, duces a spindle rocking that represents the first genetically manipulable model for studying spindle positioning in vertebrates. The switch operates via the opening of LGN, which can normally fold back onto itself. The unfolding is triggered by binding to either membrane-...

Predictive relationships are offered for the response of on-ground 2D rigid blocks undergoing rocking. Among others, this is pertinent to (1) modern or classical antiquity structures that utilize rocking as a seismic protection mechanism and (2) freestanding contents (e.g., cabinets, bookcases, museum artifacts) located on ground lower floors stiff buildings. Blocks varying dimensions were subj...

This paper is a preliminary report of in vitro studies comparing platelet storage in the new polyolefin PL732 packs with the present polyvinyl PL146 packs. The parameters used to assess platelet viability in these studies were the recovery from the hypotonic stress test (HST) and the pH. The effect of the mass of concentrate was assessed by preparing 20 g, 35 g and 50 g packs. The method of agi...

In vitro mechanotransduction studies, uncovering the basic science of the response of cells to mechanical forces, are essential for progress in tissue engineering and its clinical application. Many varying investigations have described a multitude of cell responses; however, as the precise nature and magnitude of the stresses applied are infrequently reported and rarely validated, the experimen...
