In one sentence, describe what the following article is about: Then position the free hand onto the opposite shoulder, and roll the victim onto the side with the straight leg. The raised knee/bent leg is on top and helps stop the body from rolling over onto the abdomen. The arm with the hand tucked under the edge of the hip is kept from sticking out in the way when rolling the patient onto that side. This position keeps saliva from accumulating in the back of the mouth or throat, and helps the tongue to hang to the side without it falling/flopping into the back of the mouth and obstructing the airway. This position is important for near drownings or overdose if there is a risk of vomit.
Summary: Position the patient only after the victim has been stabilized and is breathing on his/her own. Flex and raise one knee joint, push the victim`s hand that's on the opposite side from the raised knee, partially under the hip with the straight leg. Use the recovery position to help the victim to breathe more easily.

In one sentence, describe what the following article is about: A wave function or wave function is a mathematical tool in quantum mechanics that describes the quantum state of a particle or system of particles. It is commonly applied as a property of particles relating to their wave-particle duality, where it is denoted ψ(position,time) and where |ψ|2 is equal to the chance of finding the subject at a certain time and position.  For example, in an atom with a single electron, such as hydrogen or ionized helium, the wave function of the electron provides a complete description of how the electron behaves. It can be decomposed into a series of atomic orbitals which form a basis for the possible wave functions. For atoms with more than one electron (or any system with multiple particles), the underlying space is the possible configurations of all the electrons and the wave function describes the probabilities of those configurations. In solving homework problems involving the wave function, familiarity with complex numbers is a prerequisite. Other prerequisites include the math of linear algebra, Euler's formula from complex analysis and the bra–ket notation.
Summary: Learn about wave function.

In one sentence, describe what the following article is about: They can include muscle weakness, loss of mobility or acute pain in the neck. There may also be numbness, tingling or sharp pains radiating down the neck and into the arm, shoulder or hand, because the bulge is being compressed into the nerve. This has been shown to reduce swelling and decrease pain by numbing the area. Ice periodically for twenty minute periods throughout the first day or two. These include ibuprofen, aspirin or Aleve. Begin immediately after the pain starts. Take the anti-inflammatory regularly for a few days, but do not take more than 2400 mg per day. After the first day or two switch from icing the affected area to heating it. Use a bath, shower or hot towel to apply moist heat. This can help to calm the muscles. When a disc herniation occurs, the muscles surrounding the cervical spine often seize up. Typically a bulging disc will improve in a few days if allowed to recover. Bed rest is not required, but limiting rotation or bad posture for a few days and resting the neck by lying down occasionally should help.
Summary:
Learn to recognize the symptoms of a disc bulge. Ice your neck immediately after the pain occurs. Take a nonsteroidal anti-inflammatory. Switch to moist heat. Limit activities that affect your neck for a few days.
