Q:trucuspid valve... pulmonary valve??
Inga, Valves are flap-like structures that allow blood to flow in one direction. The tricuspid valve is located between the right atrium and the right ventricle and prevents the back flow of blood as it is pumped from the right atrium to the right ventricle. The pulmonary valve is the structure in the pulmonary artery consisting of three flaps, which open and close during each heartbeat. The flaps keep blood from flowing back into the heart from the pulmonary artery which is the artery that supplies blood to the lungs. Hope this helps matador 89
Q:bent exhaust valve?
make sure you dont have any of the spark plug wires crossed (like 5 7). If you do, you'll get a backfire out of the exhaust or carb.
Q:Is it safe to ride a motorcycle with tapping valves?
Drop off the tapping bandit at the shop. The adjustment will be made and presto back in business. Dont't be silly look around for an independent garage owner that will do it for $50 instead of the $200 the dealer will charge. What do you mean---can't stop riding long enough. Blow the tapping in to a big thump and you might end up hospitalized---cause it broke.
Q:What are the advantages of having larger valves over two smaller ones?
All else being equal, larger valves equal less pumping loss and more top end horsepower. The problem with large valves is that at lower engine speeds, the gas velocity is too low to fill the chamber quickly and efficiently thereby compromising low-end torque. The answer to this dilemma is to have multiple small valves. This is the primary reason for current high performance engines being equipped with multiple valves per cylinder.
Q:How do you put trumpet valves in?
1) Try this first and if this doesn't work, go to #2. Oil the valve's body and gently put it back into the cylinder without screwing it in yet. Then, turn the valve until it clicks, and make sure it is really seated correct. Some trumpets have two clicks, and one is not the right one. So, you have to get the right click - which tells you that your valve is seated right. When your valve is seated right, then screw it in. 2) If you don't get a click when you spin your valve - look at the tubing on your trumpet and line up the holes in your valve with the tubing. When the valve is up, it will line up with 2 holes of the tubing, and when it is down it will line up with 2 other holes in the tuning. So, you can determine the correct positioning of the valve by looking at the tubing on your trumpet. But this is a last resort. I've never seen a trumpet where the valves don't click when you turn them.
Q:Articifical Heart Valves -?
There are three of these things: the caged-ball which utilizes a metal cage to house a metal ball, tilting-disc valves, which have a single circular occluder controlled by a metal strut. They are made of a metal ring covered by a tissue, into which the suture threads are stitched, in order to keep the valve in place once implanted and there's bileaflet valves, which consist of two semicircular leaflets that rotate about struts attached to the valve housing which is the most recent type, eh? So heart valves are considered to be extremely durable. They're made of either pyrolytic carbon or titanium coated with pyrolytic carbon, and the sewing ring cuff is Teflon or polyester or dracon (probably dacron :P). They key to the materials chosen is durability because of the constant fluid flow. I see this as pure engineering, not medicine, specifically fluid mechanics: like if there are rare complications for example thrombus formation is a debilitating side effect of high shear stresses created by design of the valves. Ideal heart valve from an engineering view would produce minimal pressure drops of course have small regurgitation volumes because it's supposed to minimize turbulence and regulate the flow.
Q:Valve amps?!?
Marshall were big name in Amps when pretty well everything electronic used valves. Some valves were quite small, some larger, and some are still used today in powerful transmitters. There are those who swear that the sound produced by a valve amplifier is far better than a solid state one. Valve technology takes up much more space than solid state, so miniaturisation is a problem, and also uses much more power and produces a lot of heat. Now solid state is capable of producing high power audio amplifiers which use less power and take up less space, so have become the preferred method. Nevertheless, there is a strong following even today for a good high powered valve amplifier. And yes, it is quite possible to have a valve and solid state mix. The solid state works at the input stage, and the valves take over at high power output levels, but I am not sure what the purists would think about this hybrid usage .
Q:Mitral Valve Prolapse and headache...any relation?
Although mitral valve prolapse is a lifelong disorder, many people with this condition never have symptoms. When diagnosed, people may be surprised to learn that they have a heart abnormality. When signs and symptoms do occur with mitral valve prolapse, it's typically because blood is leaking backward through the valve (regurgitation). Symptoms can vary widely from one person to another. They tend to be mild, develop gradually and may include: A racing or irregular heartbeat (arrhythmia) Dizziness, lightheadedness Difficulty breathing or shortness of breath, often when lying flat or during physical exertion Fatigue Chest pain that's not associated with a heart attack or coronary artery disease When your heart is working properly, the mitral valve closes during contraction of the left ventricle to prevent blood from flowing back into your heart's upper left chamber (left atrium). But in some people with MVP, the mitral valve malfunctions. In these people, the mitral valve leaflets are abnormal with extra tissue, bulging (prolapsing) like a parachute into their left atrium each time the heart contracts. The bulging may keep the valve from closing tightly. This may not cause problems if only a small amount of blood leaks back into the atrium. When blood leaks backwards through the valve, it's called mitral regurgitation (MR). MR can cause symptoms. Take care always! OIRAM
Q:Intercoolers and Blow off valves, turbos?
A blow off or pop off valve controls the boost or pressure the turbo or supercharger is pushing into the engine.A turbo makes the boost.The blow off valve controls it so you wont run too much boost or pressure into your engine and leave pieces of it all over the street.The blow off valve can be adjusted to control the boost,6- 8 lbs.should be sufficient for a street application.The blow off valve simply allows the excess pressure built up in the turbo to be vented or blown off so it wont be forced into the engine.The boost on a supercharged or blower application is controlled by swapping the blower pulley to either underdrive the blower or overdrive the blower,depending on which way you want to go.
Q:artificial heart valves and CPR?
Yes, and it doesn't matter if there are artificial valves or not. The thing about CPR is that it's only done for someone who is actively trying to die. The alternative to doing CPR is to let someone pass away, which is not usually the best course of action (unless they have a terminal disease and have asked not to be resuscitated.) If you are asking whether the presence of heart valves excuses someone from NOT doing CPR... then no. If you are asking whether heart valves + CPR and a bad outcome is because CPR should not have been done, then no to that too. The right thing to do for someone who is pulseless is to start CPR, call 911 and get more definitive treatment on the way. CPR is not going to revive someone - it is only a bridge until a defibrillator and/or cardiac drugs are available. I'm sorry that you lost your wife at such a young age, and I hope you find the answers you are looking for.
