A double-blind, placebo-controlled investigation of the effects of two doses of a valerian preparation on the sleep, cognitive and psychomotor function of sleep-disturbed older adults (2004)
Journal Article
Diaper, A., & Hindmarch, I. (2004). A double-blind, placebo-controlled investigation of the effects of two doses of a valerian preparation on the sleep, cognitive and psychomotor function of sleep-disturbed older adults. Phytotherapy Research, 18(10), 831-836. https://doi.org/10.1002/ptr.1574

One of the most popular herbal remedies for the alleviation of sleep problems is valerian. However, research into valerian is sparse, and studies differ greatly with respect to design, measures, and preparations used. This clinical study used standar...

The relationship between the sagitta of the anterior corneal surface and refractive error of the eye (2004)
Journal Article
Garner, L. F., & Owens, H. (2004). The relationship between the sagitta of the anterior corneal surface and refractive error of the eye. Optometry and Vision Science, 81(8), 636-639. https://doi.org/10.1097/01.opx.0000141798.41340.8b

Changes in the sagitta of the anterior corneal surface associated with a change in the corneal radius of curvature have been used to calculate the change in refractive error of the eye in two areas: the ablation depth for laser surgery, and the chang...

Posterior corneal changes with orthokeratology (2004)
Journal Article
Owens, H., Garner, L. F., Craig, J. P., & Gamble, G. (2004). Posterior corneal changes with orthokeratology. Optometry and Vision Science, 81(6), 421-426. https://doi.org/10.1097/01.opx.0000135097.99877.5d

Purpose. To investigate changes in corneal thickness and the radius of curvature of the posterior corneal surface after orthokeratology (OK) rigid lens wear. Methods. Nineteen young myopic subjects wore reverse-geometry OK lenses (BE/ABE, Ultravision... Read More about Posterior corneal changes with orthokeratology.

Speed and accuracy of head- and eye-based aiming systems at high vertical acceleration (2004)
Journal Article
Ineson, J., Durnell, L., Ebbage, J. L., Jarrett, D. N., Neary, C., & Reed, M. A. (2004). Speed and accuracy of head- and eye-based aiming systems at high vertical acceleration. Aviation, Space, and Environmental Medicine, 75(5), 420-428

BACKGROUND The benefits of using a head tracker in a fast jet to aim weapons and control sensor direction have been amply demonstrated, but head direction is difficult to control at high G. An experiment was conducted to assess whether aiming usin... Read More about Speed and accuracy of head- and eye-based aiming systems at high vertical acceleration.
