A method is described for production of time series of atmospherically distorted wavefronts following Kolmogorov statistics. The method uses Taylor's hypothesis (`frozen turbulence') to generate the temporal development of the aberrations caused by an atmospheric turbulence layer. An arbitrary number of turbulence layers can be used to generate the final wavefront.

In dipteran insects the most distal telomere-associated DNA known to exist consists of long, complex tandem repeats. We have classified the 340-bp tandemly arranged repeats in Chironomus pallidivittatus. The repeats are distributed in a small number of subfamilies. One type of the repeat has the character of a master unit from which other main units can be derived usually by simple changes. The de
Early discharge and home rehabilitation (EDHR) for stroke patients seems logical as an alternative to rehabilitation in stroke units, as these patients often show impaired ability to perform activities of daily living. The objective of this review is to present the effects of EDHR for stroke patients on health, quality of life and costs, and to describe the physiotherapy provided. Seventeen random
BACKGROUND: Pin-site infection and pin loosening are complications that can cause discomfort to the patients. The purpose of present study was to evaluate pin-site infection, pain, and the use of medications using the XCaliber pin (Orthofix) with optimized thread and tip design, and the commonly used standard pin (Orthofix) during the procedure of hemicallotasis osteotomy (HCO). MATERIAL AND METHO
A method to determine the dynamic load between two rotating elastic helical gears is presented. The stiffness of the gear teeth is calculated using the finite element method and includes the contribution from the elliptic distributed tooth load. To make sure that the new incoming contacts which are the main excitation source are properly simulated, the necessary deformation of the gears is determi
Aim:To study the effects of hypobaric pressure chamber exposure on the cochlear frequency selectivity of subjects with monaural, fluctuating, low-frequency hearing loss, such as occurs in Ménière's disease.Methods:We used a hypobaric pressure chamber to create relative underpressure in the ear canal, in order to impose positive pressure gradients on the inner ear. Psychophysical tuning curves, tra
Standard lot-sizing models are often not directly applicable in practice. Different assumptions in lot-sizing models and the extent to which these assumptions are valid in various practical situations are discussed. Practitioners also tend to prefer simple standard methods even for complex problems, which means that adjustment of the lot sizes may be desirable. The ways in which such adjustments c
