[1] Natural pieces of wood provide a variety of ecosystem functions in streams including habitat, organic matter retention, increased hyporheic exchange and transient storage, and enhanced hydraulic and geomorphic heterogeneity. Wood mobilization is a critical process in determining the residence time of wood. We documented the characteristics and locations of 865 natural wood pieces (>0.05 m i...

This paper analyses the influence of horizontal bracing restraints provided by the friction between pallet bases and rail beams on the static behaviour and design of steel drive-in storage racks. The pallet bracing restraints are shown to significantly influence the structural behaviour of the rack, and their effect on the bending moment distribution of the uprights is studied in the paper. The...

We prospectively studied the benefits and risks of prolonged treatment with the Pavlik harness in infants with idiopathic developmental dysplasia of the hip. Bracing was continued as long as abduction improved. It was started at a mean age of four months (1 to 6.9). Outcome measures were the number of successful reductions, the time to reduction, the acetabular index and evidence of avascular n...

The biomechanical mechanisms of lower-limb injuries in the New Zealand Defense Force were identified from the circumstances of the injuries, and injury prevention strategies that addressed these mechanisms examined for their applicability to a military setting. Many of the injuries were the result of rolling or twisting movements and ankle instability was a common causal factor. Ankle bracing a...

Objectives—To investigate the eVect of bracing and taping on selected electromyographic, kinematic, and kinetic variables when landing from a jump. Methods—Fifteen netball players performed a jump, so as to land on their dominant limb on a force plate. Electromyographic activity was recorded from the gastrocnemius, tibialis anterior, and peroneus longus muscles. Subjects were also filmed and me...

OBJECTIVE To access the acceptability of Steenbeek brace by children undergoing clubfoot correction and their parents to ensure long-term compliance. METHODS The cross-sectional study was conducted at the Indus Hospital, Karachi from October 2013 to March 2014. A trained researcher interviewed the person primarily responsible for bracing the child using a pre-coded questionnaire. Modified Ort...

Design and detailing requirements of seismic provisions for concentrically braced frames ~CBF! were specified based on the premise that bracing members with low KL /r and b / t will have superior seismic performance. However, relatively few tests investigate the cyclic behavior of CBF. It is legitimate to question whether the compression member of CBF plays as significant a role as what has bee...

Helmet-mounted systems (HMS), such as night vision goggles and helmet-mounted displays, are designed to enhance pilot performance. Using HMS, however, may also affect pilot safety by increasing the potential for neck injury during ejection due to the increase in dynamic forces generated in the cervical spine as a result of the change in helmet inertial properties. Pilot bracing techniques may a...

In this paper the authors analysed four single-layered braced barrel vaults with different types of bracing. Each vault covered area 20 m × 28 and was made from steel hollow sections. The static-strength analyses structures were conducted using Autodesk Robot Structural Analysis program, taking into account self-weight, glass cover, snow load wind load. case load, pressure perpendicular to long...

To explore the difference in impact of transverse bracing on seismic effect through concrete-filled steel tube arch bridges with non-isolated and earthquake-isolated, nine earthquake-isolated structural models under different cross-bracing arrangements were established, Elcentro waves selected. The internal force, displacement, velocity, absolute acceleration, relative separation ribs each mode...
