PURPOSE To evaluate and correlate the peaks and the fluctuation of intraocular pressure seen in the association of the ambulatory intraocular pressure curve with the water-drinking test versus the peaks and the fluctuation seen in the daily intraocular pressure curve. METHODS The sample was as follows: 77 eyes belonging to 77 patients who were divided into three groups composed of 31 eyes bel...
The water wave generation by wave paddle and a freely falling rigid body are examined by using an Incompressible Smoothed Particle Hydrodynamics (ISPH). In the current ISPH method, the pressure was evaluated by solving pressure Poisson equation using a semi-implicit algorithm based on the projection scheme and the source term of pressure Poisson equation contains both of divergence free ve...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
In water supply systems, One of the most important components as safety unit and the current controller (Switching flow and regulate the amount of flow) used in the arrangement of lines of water. In this study, according to multiple ponds in Tanguiyeh dam water pipeline to industrial and mining company Gol Gohar Sirjan Butterfly valve used in these ponds using Fluent software simulation has bee...
Observations from basal water-pressure sensors along the length of Bench Glacier, Alaska, USA, show that diurnal fluctuations of water pressure are seasonal and restricted to summer. Most notable about these fluctuations is their disappearance in the late summer and early autumn, long before the seasonal end of diurnal meltwater input. Here we present data documenting the end of diurnal water-p...
removing of ions from different water and waste water is one of the most important of nanofiltration potential for different aims, such as softening of potable water, remove of heavy metal ions and purification of waste water to reuse. in this study nanofiltration was used to remove of the most important ions (na+, k+, ca2+, mg2+, so42-, cl-) in sugar beet press water to reuse of this stream. e...
Inspiration through -7cm H2O resistance results in an increase in venous blood flow back to the heart and a subsequent increase in cardiac output and blood pressure in hypotensive animals and patients. Breathing through the impedance threshold device with 7cm H2O resistance (ITD-7) also reduces intracranial pressure with each inspiration, thereby providing greater blood flow to the brain. A new...
Generally seepage analysis and stress–strain analysis are conducted separately in the analysis of dams with varied water levels, which neglects the impact of soil deformation on seepage. The impact, however, is significant when the water level varies greatly. In this study, a simplified approach for consolidation analysis of unsaturated soil is used to conduct numerical simulations of water-fil...
S OF SCIENTIFIC AND TECHNICAL PAPERS2 Reprint 107. THE DRAINAGE OF LAND OVERLYING ARTESIAN BASINS. By W. Gardner. O. W. Israelsen, and W. W. McLaughlins • In SOIL SCIENCE, Vol. 26, No.1 (July, 1928), pp. 33-45. The methods of hydrodynamics are used in an effort to calculate the influence of drain tile and of wells on the water-logged condition of fine-textured .oils due to hydrostatic pressure in
