BACKGROUND Single-use rocking-motion-type bag bioreactors provide advantages compared to standard stirred tank bioreactors by decreased contamination risks, reduction of cleaning and sterilization time, lower investment costs, and simple and cheaper validation. Currently, they are widely used for cell cultures although their use for small and medium scale production of recombinant proteins with...

INTRODUCTION Infantile colic is a painful condition in the first months of infancy. This study was carried out with the aim of testing the hypothesis that massage treatment has a clinically relevant effect on this condition. MATERIALS AND METHODS This randomized clinical trial was conducted among 100 infants of < 12 weeks of age with infantile colic. They were randomly assigned to either infa...

A randomized study was done to compare non pharmacological methods to reduce the pain of heel pricks in 104 stable term neonates. Non-nutritive sucking (NNS), rocking, massage, sucrose (20 percent), distilled water (DW) and expressed breast milk (EBM) were used as pain reducing agents. Duration of cry and Douleur Aiguë du Nouveau né (DAN) score were used to assess pain. Physiological parameters...

The mechanism of earthquake energy input to building structures is clarified by considering the surface ground amplification and soil-structure interaction. The earthquake input energies to superstructures, soil-foundation systems and total swaying-rocking system are obtained by taking the corresponding appropriate free bodies into account and defining the energy transfer functions. It has been...

A tuned mass rocking wall (TMRW)-frame structure system is proposed to improve the energy dissipation ability of traditional wall-frame system. Based on principle damper (TMD), a TMRW designed with proper and stiffness according dynamic characteristic host structure. Firstly, considering presence inherent structural damping, amplification factor main was derived from equations mechanism. practi...

The effects of linear vestibular stimulation on body-rocking behaviors in adults with profound mental retardation were studied. A single-system multiple base-line design across 3 subjects was used. The design included three phases spread over a period of 9 weeks. An interval time sampling procedure was used to collect data. Data from the 3 subjects were graphed and interpreted through visual in...

The large majority of three-dimensional structures of biological macromolecules have been determined by X-ray diffraction of crystalline samples. High-resolution structure determination crucially depends on the homogeneity of the protein crystal. Overall 'rocking' motion of molecules in the crystal is expected to influence diffraction quality, and such motion may therefore affect the process of...

We have performed a comparison of magnetoresistance and structure of epitaxial and textured Fe/Cr superlattices grown by molecular-beam epitaxy ~MBE! and magnetron sputtering with either ~110! and ~100! orientations on a variety of substrates. MBE samples grown along the ~100! orientation, exhibit narrower rocking curves ~mosaic spread! and lower saturation resistivities than sputtered samples....
