background: infantile colic, cry-fuss and sleep problems are transient in the initial months of life, but they contribute to maternal depression, parenting stress and family mental health problems. in this randomized clinical trial, we aimed to explore the efficacy of massage therapy compared to rocking in reducing infantile colic symptoms including duration and number of cries, sleep duration ...

Residual drifts after severe earthquakes interrupt serviceability of buildings. Retrofitting of such buildings is in many cases very difficult and consumes lots of time and money. Recently, there are some attempts to develop the seismic design procedures to not only satisfy life safety criteria but also lead to more economical buildings. One of these modern methods of improving seismic performa...

Rocking stability of a rigid prismatic block standing on base subject to simple harmonic acceleration function is still an important dynamics problem, in which energy loss often not treated accurately enough. The at impacts during rocking here examined. for various slendernesses and sizes assessed numerically, where improved coefficient capable estimating the size effect considered. A number re...

Introduction. Pedicle based posterior dynamic stabilization systems aim to stabilize the pathologic spine while also allowing sufficient motion to mitigate adjacent level effects. Two flexible constructs that have been proposed to act in such a manner, the Dynesys Dynamic Stabilization System and PEEK rod, have yet to be directly compared in vitro to a rigid Titanium rod. Methods. Human lumbar ...

In Azerbaijan oil production is carried out both in the offshore and onshore. Offshore on special platforms, while onshore exploitation directly by a mechanized method. Thus, object of study downhole pumps, which consist surface mechanical transmission equipment. For direct mechanization ground equipment, device called rocking machine used, consisting converting mechanisms. The main task to ens...

In order to investigate the seismic performance of prestressed concrete rocking frame (PCRF), a theoretical model based on rigid body is established for one-story single-span PCRF. The PCRF studied in this paper has connecting interfaces set at column feet and inner faces beam–column joints, allowing columns be uplifted with accompanying separation interface rotation beam around interface. tend...
