The Khuran Channel, Southern Iran (26°45’N), is a topographically complex channel which is open at both ends. Owning to its particular geometry, this narrow channel is subjected to strong tidal currents.Across-channel distribution of the mean and tidal flows were obtained over a semidiurnal tidal cycle in the Khuran Channel where the highest tidal velocity in the third day of the seco...

variability of tidal volume and respiratory rate in normally breathing man has long been demonstrated [1]. however because of lack of knowledge and technology primary ventilators could only deliver a fixed tidal volume in a fixed rate the so called volume controlled ventilation (vcv). vcv was volume preset time triggered and cycled and there was no synchronization with patient’s breaths. at tha...

Traditionally, tidal prediction was carried out using the harmonic method, which is based on the identification of the harmonic constituents existing in the tidal record. Unfortunately, however, unless long tidal records are available at the tide gauges, some important tidal constituents may not be identified. This, in turn, deteriorates the accuracy of the tidal prediction. Additionally, tidal...

introduction: capnography, is an easy, fast and practical method which its application in the diagnosis of pulmonary thromboendarterectomy (pte) has recently been studied. this study aimed to assess the diagnostic value of end-tidal co2 (etco2) and the alveolar dead space (avds) in the diagnosis of patients suspected to pte who have been referred to the emergency department. materials and metho...

The most demanding applications are tidal gravity predictions. We examine if the nms precision can be reached. It correspond roughly to a 4.10 of the tidal range (TR) at mid latitude. High precision tidal prediction requires either tidal factors derived from tidal observations or modelled tidal factors based on the response of the Earth to tidal forces and on the ocean tides contribution. Both ...
