PURPOSE To compare core muscle activity during resistance exercises performed on stable ground vs. the BOSU Balance Trainer. METHODS Twelve trained men performed the back squat, dead lift, overhead press, and curl lifts. The activity of the rectus abdominis, external oblique abdominis, transversus abdominis/internal oblique abdominis, and erector spinae muscles was assessed. Subjects performe...

*Correspondence: Ben J. Stuart , 122 Stocker Center, Athens, OH 45701, USA e-mail: [email protected] A novel 28 L photobioreactor for growing algae was developed using fiber optics for internal illumination.The proposed design uses the air-lift principle to enhance the culture circulation and induce light/dark cycles to the microorganisms. Optical fibers were used to distribute photons inside the...

Predicting the dispersal of pest insects is important for pest management schemes. Flight-mills provide a simple way to evaluate the flight potential of insects, but there are several complications in relating tethered-flight to natural flight. We used high-speed video to evaluate the effect of flight-mill design on flight of the red palm weevil (Rynchophorous ferruginneus) in four variants of ...

When people lift objects of different size but equal weight, they initially employ too much force for the large object and too little force for the small object. However, over repeated lifts of the two objects, they learn to suppress the size-weight association used to estimate force requirements and appropriately scale their lifting forces to the true and equal weights of the objects. Thus, se...

Abstract A description is given of recent progress in the understanding mechanisms fluid-body interactions where motion a body and surrounding fluid affect each other substantially. The mathematical modelling such unsteady for internal channel external near-wall flows two spatial dimensions time. emphasis throughout on analytical developments with accompanying reduced computation. successive as...

Aim: This paper focus is to describe and evaluate the authors' personal technique for a simplified transpalpebral eyebrow lift. Methods: We performed surgery in 179 patients (95% females and 5% males) between years of 2008 and 2009. Initially, a thorough assessment of brow stability and symmetry was performed. To achieve desirable aesthetic we agreed upon the consensus that the eyebrow lateral ...

Fran is a system for functional reactive animation. This note explores the way that some of the features of Fran can be interpreted as logical formulas, referring in particular to the example of a lift animation written in Fran. [First written November 1998; revised February and April 1999.]

background and aim:  although there have been substantial developments in dental implant therapies, achieving good implant stability (isq >60) for implants inserted in augmented sinus sites appears to be challenging in comparison with non-augmented sites due to the high prevalence of bone resorption in posterior regions of maxilla. this study aimed to evaluate and compare the time required to a...
