River dynamics and sediment transport play an important role in river bed morphology. Building a bridge pier along the alters cross-section of causes change flow processes. These changes are mainly responsible for scour. In this paper, usage collars to reduce scour around circular piers has been investigated. The with different diameters depth positions have studied using previous data addition...

Cervical immobilisation is commonly applied following trauma, particularly blunt head injury, but current methods of immobilisation are associated with significant complications. Semi-rigid disposable cervical collars are known to cause pressure ulcers, and impede effective airway management. These collars may also exacerbate a head injury by increasing intracranial pressure as a result of exte...

BACKGROUND The use of electronic training devices for dog training is controversial. The aims of this study were to give an indication of the extent to which dog owners use these devices in England, identify factors associated with their use, and compare owner report of outcomes. A convenience sample of dog owners in England was used to identify numbers using electronic training devices and ide...

The location error of uncorrected data from Global Positioning System (GPS) collars range from ca. 45.5 to 65.5 m (Rempel et al. 1995). Improvements that potentially could reduce locational error to <10 m include correcting systematic-bias by reference to GPS data collected at a known position (differential correction), increase in the proportion of positions based on ranging 4 rather than 3 sa...

Pressure ulcers related to cervical collars are a common difficult-to-manage complication of cervical immobilization in the trauma patient. After many cases of occipital pressure ulcers occurred at our institution, a multidisciplinary task force was formed to look at this issue. The group was to identify causes for this problem and develop a plan to decrease the occurrence of pressure ulcers re...
