Disadvantages. 1  IPV induces very low levels of immunity in the intestine. As a result, when a person immunized with IPV is infected with wild poliovirus, the virus can still multiply inside the intestines and be shed in the faeces, risking continued circulation. 2  IPV is over five times more expensive than OPV.
Hello, Thanks for your question. vibration in the absence of any pain in right lower abdomen is likely related to the muscle twitchings. The abdominal muscles can twitch giving vibration sensations. This can happen due to: 1. Dehydration---common cause. Plenty of fluids (sports drinks like Gatorade) should resolve the issue. 2. Nerve impingement---nerve impingement at the lower spine can cause vibration sensation. 3. Systemic conditions: diabetes, vitamin deficiencies can affect the local nerves causing this sensation. Improve your diet & take a multivitamin supplement daily.
Through resonance, a comparatively weak vibration in one object can cause a strong vibration in another. By analogy, the term resonance is also used to describe the phenomenon by which an oscillating electric current is strengthened by an electric signal of a specific frequency.An example of resonance is provided by a motor that causes vibration in a piece of furniture in another part of the same house.These vibrations occur because the furniture has a natural frequency equal to the frequency of the vibrations set up by the motor.The furniture is said to be in resonance with the motor.echanical resonance can produce vibrations strong enough to destroy the object in which they occur. For example, soldiers marching over a bridge can set up extreme vibrations at the bridge's natural frequency and shake it apart.
