Biodegradable electrospun polycaprolactone scaffolds can be used to support bone-forming cells and could fill a thin bony defect, such as in cleft palate. Oscillatory fluid flow has been shown to stimulate bone production in human progenitor cells in monolayer culture. The aim of this study was to examine whether bone matrix production by primary human mesenchymal stem cells from bone marrow or...

Signals transmit information to receivers about sender attributes, increase the fitness of both parties, and are selected for in cooperative interactions between species to reduce conflict [1, 2]. Marine cleaning interactions are known for stereotyped behaviors [3-6] that likely serve as signals. For example, "dancing" and "tactile dancing" in cleaner fish may serve to advertise cleaning servic...

X-ray rocking curve and topograph measurements were carried out at CHESS in Cornell University in November 2006. The purpose of this experiment was to check if the X-ray facility at CHESS is suitable to be used for GlueX in assessing diamond crystal quality and investigating radiation damage and surface deformation induced by milling. After modifying the C1 beam line by using an asymmetry silic...

Primarily, two models are commonly used to describe rocking of rigid bodies; the Housner model, and the Winkler foundation model. The first deals with the motion of a rigid block rocking about its base corners on a rigid foundation. The second deals with the motion of a rigid block rocking and bouncing on a flexible foundation of distributed linear springs and dashpots (Winkler foundation). The...

Controlled rocking of steel braced frames has been proposed for the seismic retrofit of structures. The controlled rocking approach allows a frame to uplift from its support at the base-of-column to foundation interface while displacementbased steel yielding devices are implemented at the base location to control the response. Past studies have focused on analytical investigations of the respon...

Because of difficulty in inspection and retrofit of foundation in comparison with other elements, the common design philosophy is to avoid any nonlinear deformation in the foundation. This paper shows that by employing controlled foundation nonlinearity, in predetermined sections with arrangements for inspection and retrofit, it is possible to reduce seismic demand on superstructure. Localizing...

(1998) Rocking chair therapy for dementia patients: Its effect on psychosocial well-being and balance

During the past years, cardiac resynchronization therapy (CRT) has become a recognized treatment option for patients with heart failure and conduction delays. In the meantime, the principle of re-synchronizing a dyssynchronous ventricle can be regarded as established. The challenge of correctly identifying the patient candidates who will benefit from this costly and not completely noninvasive t...

Clinical vignette: A 76-year-old man consults you for increasing shortness of breath over the past two years and an increasing requirement for home oxygen. A video-assisted thoracoscopic lung biopsy shows findings of usual interstitial pneumonitis, and he has no identifiable cause for pulmonary fibrosis, so he is considered to have idiopathic pulmonary fibrosis (IPF). His diffusing capacity for...
