Strong antibacterial polydopamine (PDA) coatings prepared by a facile shaking-assisted method is reported for the first time. It was found that a minor modification made to the conventional synthesis procedure of PDA coatings, viz. replacing the static solution condition with a shaking solution condition by using a mechanical shaker, can produce the roughened polydopamine (rPDA) coatings at dif...

The aim of the present study was to investigate the potential effects of mechanical shaking on the purity, activity, differentiation and possible apoptosis of rat bone marrow mesenchymal stem cells (BMSCs). Based on the whole bone marrow adhesion method, different durations and frequencies of mechanical shaking were used on primary cells. The biomarkers, CD29, CD90, CD45 and CD31, in addition t...

On February 27, 2010, the central-south part of Chile was affected by a strong ground motion of Magnitude 8.8, that induced moderate values of peak ground acceleration (PGA) on rock outcrops, in the range of 0.13g to 0.32g, while in soil deposits, a maximum PGA of 0.94g was recorded. The duration of the shaking was close to two minutes as it is substantiated by the available acceleration record...

Abstract The San Gabriel, Chino, and Bernardino sedimentary basins in Southern California amplify earthquake ground motions prolong the duration of shaking due to basins' shape low seismic velocities. In event a major rupture along southern segment Andreas fault, their connection physical proximity Los Angeles (LA) can produce waveguide effect strong motions. Improved estimates depth sediment‐b...

Few studies have investigated the prevalence of shaking and smothering and whether they are associated with co-sleeping. In Japan, co-sleeping is common during infancy and early childhood. This study investigates the prevalence of shaking and smothering and their associations with co-sleeping among 4-month-old infants in Japan. A questionnaire was administered to mothers who participated in a 4...

Limb-shaking is a specific clinical feature of transient ischaemic attacks that has been associated with a high-grade stenosis or occlusion of the internal carotid artery. The aim of this study was to describe the clinical characteristics of limb-shaking in patients with internal carotid artery occlusion and to investigate whether patients with limb-shaking have a worse haemodynamic state of th...

In large earthquakes, damaging ground motions may occur at large epicentral distances. Because of the relatively slow speed of seismic waves, it is possible to construct a system to provide short-term warning (as much as several tens of seconds) of imminent strong ground motions from major earthquakes. Automated safety responses could be triggered by users after receiving estimates of the arriv...
