Console Basics. Consoles are specialized, prepackaged computers designed, first and foremost, for playing video games on your TV. They tend to be much cheaper than gaming PCs, but they only work with games made for a given system. The PlayStation 4, for example, only supports PlayStation 4 games.
1. CORNEAL DIAMETER- HVID OPTOM FASLU MUHAMMED. 2. ï¨ Technique 1: ï¨ Corneal Topographer :use the biometric ruler within the corneal topography software program to measure your patientâs horizontal visible iris diameter (HVID). ï¨ It may be necessary to measure at a 45 degree oblique angle as the topographer may cut off part of the cornea in the horizontal plane.
Hydraulic Head. H is a measure of the mechanical energy that causes groundwater to flow. Hydraulic head (h) can be calculated two ways: 1. the sum of pressure head (h p) and elevation head (z), or h=(h p + z). 2. the difference between the land surface elevation and depth to water, or h=(land elevation-depth to water).elocity of Groundwater Movement Based on Darcy's work, we can estimate the velocity of water or how fast the water is moving between points. Velocity is calculated by using hydraulic conductivity, porosity, and hydraulic gradient.
