What is meant by air to open valve?
An increase in air pressure to the actuator is required to cause the valve to open. This is called Air-to-Open Valve. Otherwise normally called Fail-Closed or Normally Closed Valve. An increase in air pressure to the actuator is required to cause the valve to close. This is called Air-to-Close Valve. Otherwise normally called Fail-Open or Normally Open Valve. Another way of looking at these definitions are: When air is given from the bottom of the diaphragm, the stem will go up and flow enters from the input and flows to the output. This is called Air-to-Open. When air is given from the top side of the diaphragm, the stem will go down and the stem will close the plug into the seat, meaning that the flow would be shut-off and the valve will be closed. Basically, you need air to either open or close the valve to allow your flow to proceed or shut.
What is the difference between malthus and boserup theories?
- Ester Boserups theory was that as the generations grow so will the population and as we grow into the future we will become cleverer, smarter and learn more things. This means that we shouldn't worry about running out of resources and food, because as we grow into the future we will create a new way of avoiding the problems, increase the food supply and discover and create more resources. - Thomas Malthus's theory was that as we grow into the future people that two people will have four children, those people will have eight children and so on -it will double the amount before it. And as we double into the future the population will grow out of hand that there will not be enough resources and supplies to meet the needs of these people. So the population will overtake the amount of resources.
Why reading is good for your brain?
Sir Richard Steele once said, " Reading is to the mind what exercise is to the body." When you read, you learn. You're actually exercising your brain, because reading makes you think. Even if you're reading a work of fiction, it takes effort to translate the words on the page into mental pictures. You may not realize this as you're reading, but you've become actively involved, unlike when watching television. TV keeps you passively involved, as your brain simply soaks in what's happening on the screen, whereas with reading, you're actively participating. Studies have shown that reading stimulates your brain, allowing your mind to remain sharp even into old age. If you fail to exercise your brain, your brain will begin to fail. You've heard that if you don't exercise your body, your muscles will decline. The same goes for your mind. If it isn't exercised regularly through reading or studying, it, too, will begin to deteriorate. Learning something new, such as a foreign language, will challenge your brain and force it to create stronger links between memory cells. Reading, also, causes your brain to work harder, which builds stronger brain cell connections.
What are the factors that affect the listening skills of students?
1. Delivery. Providing a variety of tones (rather than a drone) helps people listen. If you are using powerpoint, don't have every word that you are saying on the screen--just the highlights. 2. Eye contact. Powerpoint may keep you on track, but be sure to keep your eyes on the audience and connect. 3. Wait. If you ask a question, wait 20 seconds for an answer. If the person is long winded, wait until they take a breath and then jump right back in. No one really wants to hear from the audience. 4. Move around. Not necessarily pacing, but give them something different to look at. 5. Watch your mannerisms--they can be distracting.
Importance of ninhydrin test in clinical or research laboratory?
Approximately 5% of patients with cervical dystonia receiving repeated botulinum neurotoxin A (BoNT/A) injections develop secondary loss of treatment benefit. Currently available tests to directly detect neutralizing BoNT/A antibodies (BoNT/A-AB) are either expensive or time consuming. To establish a simple, clinically useful test for antibody detection, we adapted the ninhydrin sweat test (NST). Eighteen dystonic patients with secondary nonresponse and clinically suspected BoNT/A-AB formation were tested for BoNT/A-AB in the mouse diaphragm test (MDT). In addition, the size of the anhidrotic area was determined by the NST 21 days after an intradermal dose of 10 U Dysport into the hypothenar region of the left palm. In nine patients, positive BoNT-AB titers were found in the MDT. There was a significant correlation between the BoNT/A-AB titers and the anhidrotic area (Spearman's rho = -0.9, P < 0.0001). Both tests provided comparably good results with respect to qualitative antibody detection. In the clinical situation of secondary nonresponse to BoNT/A therapy, the economical NST may be a helpful tool to detect neutralizing BoNT/A-AB.© 2004 Movement Disorder Societyhttp://www3.interscience.wiley.com/journal/107632044/abstract?CRETRY=1&SRETRY=0© 2004 Movement Disorder Society
What nerve stimulates the diaphragm?
ulna
What stimulates diaphragm?
The diaphragm is primarily stimulated to contract by the phrenic nerves, which originate from the spinal cord. The phrenic nerves send signals to the diaphragm to contract and initiate breathing. Additionally, chemical factors like excess CO2 levels in the blood can also stimulate the diaphragm to increase breathing rate.
How does the diaphagm move?
The diaphragm is a muscle. When it is contracted (i.e., tightened) it creates a relative vacuum which sucks air into the lungs (inhalation) from the environment. When it is let loose, the air is pushed back out (thus exhaled). The phrenic nerve stimulates the diaphragm to contract.
What is the major nerve stimulating the diaphragm?
While reading " Structure and Function of the Human Body" I believe the correct answer is the phrenic nerve. Hope this helps. the nerve that stimulates is the phrenic nerve but it arises from the cervical plexus
What are the effects of laughter?
Laughter appears to release tension in the diaphragm and relieve pressure on the liver and other internal organs. It stimulates the immune system, reduces stress, and helps balance the body's natural energy fields or auras.
What is the sheet of muscle located between the chest and abomen?
it is called the diaphram.
What is the human diaphragm made out of?
The diaphragm is not made out of bone, but the diaphragm is a muscle.
What is the dome-shaped muscle that aids in breathing?
The muscle you are referring to is the diaphragm. It also separates the thoracic cavity from the abdominopelvic cavity.
Muscle separating the chest and abdomen?
the diaphragm is the muscle separating the chest and the abdomen
What is diaphragm cancer?
what is diaphragm cancer
How the diaphragm helps the lungs?
Your diaphragm contracts and expands when you breath. When the diaphragm contracts, air rushes into the lungs. When the diaphragm relaxes, air is exhaled.
What stimulates vaccination?
Vaccines stimulates the immune system to make antibodies
