PURPOSE To evaluates the role of measuring intraocular pressure (IOP) outside office-hour in primary adult onset glaucoma. METHODS This retrospective study included 100 cases of primary adult onset glaucoma. IOP readings obtained with Goldmann applanation tonometry between 7 am and 10 pm were compared to office-hour readings. RESULTS One hundred patients were enrolled (mean age: 58.64 ± 10....

Drainage dysfunction of stenotic internal jugular veins (IJVs) is considered an etiology cough headache as a result fluctuation and imbalance intracranial pressure.

A numerical study is performed to simulate the cavitating flow, evaluating applicability of different flow fluctuation pressure (FFP) models such as Singhai FFT model, modified Singhal shear strain and present strain-vorticity model. The axisymmetric blunt-body with availability experimental data selected for simulation purpose. According results, first three FFP produce nearly similar coeffici...

The vigorous development of low-head hydraulic resources and tidal energy with greater stability predictability is drawing attention to tubular turbines. However, many problems, such as incorrect unit association relationship, insufficient output, severe vibration, occur frequently in turbines, particularly when the water head low. These phenomena cannot be known through model machine tests num...

Due to the distinctive structure of test section, open jet wind tunnel generates low-frequency pressure fluctuations (LFFs) within range typical speeds. These significantly compromise quality flow field in section. The evolution and vortex is analysed through improved delayed detached eddy simulations (IDDES). LFFs control mechanism Jilin University are then studied. interaction between large-s...
