BACKGROUND/AIMS The week's cycle influences sleep, exercise, and eating habits. An accurate description of weekly weight rhythms has not been reported yet - especially across people who lose weight versus those who maintain or gain weight. METHODS The daily weight in 80 adults (BMI 20.0-33.5 kg/m(2); age, 25-62 years) was recorded and analysed to determine if a group-level weekly weight fluct...

Pneumatic Artificial Muscle (PAM) yields natural muscle-like actuator with high force to weight ratio, soft and flexible structure, and adaptable compliance for rehabilitation and prosthetic appliances to the disabled. To obtain optimum design and usage, there is significance to understand mechanical behavior of the PAM. In this study, experimental results reveal empirical modeling for relation...

this study experimentally investigates the effect of multi-walled carbon nanotubes (mwnt’s), as a reinforcing material, on the physical properties of heavy-weight oil well cements. a candidate well is selected and the properties of the cement slurry used in a problematic section of the well are tested in the laboratory. carbon nanotubes (cnt’s) are added as fibers to the cement slurry and the i...

In this study, Aluminium2024- Graphite composites containing 5, 10, 15 and 20 weight percent of graphite were produced by solid assisted melt disintegration (SAMD) technique which resulted in production of Al/Gr powder mixtures which subsequently consolidated and sintered for preparation of Al/Gr composites. In this technique, powder mixture was prepared by addition of flake graphite (mean diam...

We propose an approximation algorithm for identifying communities in dynamic social networks. Communities are intuitively characterized as “densely knit” subsets of a social network. This notion becomes more problematic if the social interactions change over time. Aggregating social networks over time can radically misrepresent the existing and changing community structure. Recently, we have pr...
