GLaDOS continues to be voiced by McLain in Portal 2, who worked with Valve every two weeks to record the majority of the dialogue for the game. [40] The frequency of her voice sessions allowed Valve to experiment with GLaDOS's lines and how they came out within the final game. [40]
Ellen McLain (born 1952 or 1953) is an American voice actress. She is best known for providing the voice of GLaDOS , the primary antagonist of the Portal video game series, the Combine Overwatch AI in Half-Life 2 , and the Administrator, the announcer in Team Fortress 2 .
The pressure at which the control pilot relieves is the functional set pressure of the PORV. When the pilot valve reaches set pressure it opens and releases the pressure from the dome. The piston is then free to open and the main valve exhausts the system fluid. The control pilot opens either to the main valve exhaust pipe or to atmosphere ...
Pilot valves are useful because they allow a small and easily operated feed to control a much higher pressure or higher flow feed, which would otherwise require a much larger force to operate; indeed, this is even useful when a solenoid is used to operate the valve. Pilot valves are often used in critical applications (e.g., emergency and SIS ...
Valve failure or dysfunction can result in diminished heart functionality, though the particular consequences are dependent on the type and severity of valvular disease. Treatment of damaged valves may involve medication alone, but often involves surgical valve repair or valve replacement. [citation needed]
Mitral valve prolapse classification. Diagnosis of mitral valve prolapse is based on modern echocardiographic techniques which can pinpoint abnormal leaflet thickening and other related pathology. Echocardiography is the most useful method of diagnosing a prolapsed mitral valve. Two- and three-dimensional echocardiography is particularly ...
The mitral valve in cases of mitral stenosis may open with an opening snap [1] [2] on the beginning of diastole. Patients with mitral valve prolapse may have a mid-systolic click along with a murmur, referred to as apical late systolic murmur. [3] Early systolic clicks may also be present in some patients. [4]
The song is played with 1/2 step down-tuned guitars, unlike most of Velvet Revolver's catalogue. Similar to "Sweet Child o' Mine" by Guns N' Roses (Slash, McKagan and Sorum's previous band), the song is in the key of D-flat Mixolydian, and is based on an arpeggiated riff around the Dsus4 chord.
