pressure resistance
31Vascular resistance — is a term used to define the resistance to flow that must be overcome to push blood through the circulatory system. The resistance offered by the peripheral circulation is known as the systemic vascular resistance (SVR), while the resistance… …
32Cerebral perfusion pressure — Cerebral perfusion pressure, or CPP, is the net pressure gradient causing blood flow to the brain (brain perfusion). It must be maintained within narrow limits because too little pressure could cause brain tissue to become ischemic (having… …
33Ship resistance and propulsion — A ship differs from any other large engineering structure in that – in addition to its other functions –it must be designed to move efficiently through the water with a minimum of external force. For thousands of years ship designers and builders …
34Rolling resistance — Figure 1  Hard wheel rolling on and deforming a soft surface, resulting in the reaction force from the surface having a component that opposes the motion. Rolling resistance, sometimes called rolling friction or rolling drag, is the… …
35Orders of magnitude (pressure) — This is a tabulated listing of the orders of magnitude in relation to pressure expressed in pascals. Magnitude Pressure lbf/in2 or dB Item 10−13 Pa 0.1 pPa Interstellar space pressure (approximate) 10 …
36Pulse pressure — is the change in blood pressure seen during a contraction of the heart. CalculationFormally it is the systolic pressure minus the diastolic pressure. [http://wiki.answers.com/Q/Why is mean arterial pressure not equal to systolic pressure minus… …
37Lord's Resistance Army insurgency — Date 1987–present Location Northern Uganda, South Sudan, Eastern DR Congo, Central African Republic Status The LRA have been militarily defeated …
38Jugular venous pressure — A man with congestive heart failure and marked jugular venous distension. External jugular vein marked by an arrow. The jugular venous pressure (JVP, sometimes referred to as jugular venous pulse) is the indirectly observed pressure over the… …
39Lateral earth pressure — is the pressure that soil exerts in the horizontal plane. The common applications of lateral earth pressure theory are for the design of ground engineering structures such as retaining walls, basements, tunnels, and to determine the friction on… …
40Pulmonary artery pressure — (PA pressure) is a measure of the blood pressure found in the pulmonary artery. Mean pulmonary arterial pressure is normally 9 18 mmHg.[1] Site Normal pressure range (in mmHg)[2] Central venous pressure 3–8 Right ventricular pressure systolic …
