A pulsar (short for pulsating radio star) is a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation. This radiation can be observed only when the beam of emission is pointing toward Earth (much the way a lighthouse can be seen only when the light is pointed in the direction of an observer), and is responsible for the pulsed appearance of emission. Neutron stars are very dense, and have short, regular rotational periods. This produces a very precise interval between pulses that range roughly from milliseconds to seconds for an individual pulsar. Pulsars are believed to be one of the candidates of high and ultra-high energy astroparticles (see also Centrifugal mechanism of acceleration).
The precise periods of pulsars make them useful tools. Observations of a pulsar in a binary neutron star system were used to indirectly confirm the existence of gravitational radiation. The first extrasolar planets were discovered around a pulsar, PSR B1257+12. Certain types of pulsars rival atomic clocks in their accuracy in keeping time.

Pulsar is a fictional character in the Marvel Universe, a member of the Shi'ar Imperial Guard.
The character first appeared as Impulse in X-Men #107 (October 1977-February 1978), and was created by Chris Claremont and Dave Cockrum.
The character subsequently appears in X-Men: Spotlight on Starjammers #2 (June 1990), Quasar #32 (March 1992), Inhumans Vol. 4 #4 (September 2000), JLA/Avengers #1 (September 2003), and Uncanny X-Men #477 (October 2006) and #480 (January 2007).
Impulse appeared as part of the "Imperial Guard" entry in the Official Handbook of the Marvel Universe Deluxe Edition #6.
Pulsar is a long-time member of the Shi'ar Imperial Guard, also known as Impulse. He is made of pure energy, and his form is only contained by his costume. He can release blasts of energy from his visor.
He was with the Imperial Guard the first time they fought the X-Men.
He was seemingly killed by Vulcan, who breached Impulse's suit. Pulsar later reappeared alive, battling alongside the rest of the Imperial Guard in an assault on the Kree, where Pulsar gravely wounded the Inhuman elite warrior, Gorgon.
The human voice consists of sound made by a human being using the vocal folds for talking, singing, laughing, crying, screaming etc. The human voice is specifically a part of human sound production in which the vocal folds (vocal cords) are the primary sound source. Generally speaking, the mechanism for generating the human voice can be subdivided into three parts; the lungs, the vocal folds within the larynx, and the articulators. The lung (the pump) must produce adequate airflow and air pressure to vibrate vocal folds (this air pressure is the fuel of the voice). The vocal folds (vocal cords) are a vibrating valve that chops up the airflow from the lungs into audible pulses that form the laryngeal sound source. The muscles of the larynx adjust the length and tension of the vocal folds to ‘fine-tune’ pitch and tone. The articulators (the parts of the vocal tract above the larynx consisting of tongue, palate, cheek, lips, etc.) articulate and filter the sound emanating from the larynx and to some degree can interact with the laryngeal airflow to strengthen it or weaken it as a sound source.
Moan is a 1999 gay pornographic horror film directed by David Thompson, and written by Alex Nixx. It is based on the 1996 film Scream.
While making popcorn, Kenny is called by an unknown person, who flirts with him. The conversation turns disturbing, and ends when a man wearing a hood and face paint breaks into Kenny's house, and rapes him. The next day, Kenny's friends discuss what happened to him, revealing that he was so traumatized from being sexually assaulted that he has suffered a mental breakdown. Investigating the attack is Deputy Derek, who questions Kenny's friends, all of whom have reasonable alibis. Derek then has sex with Ricky, and afterward Ricky mentions that Kenny had recently dumped Stuart.
After Derek leaves, dismissing a nosy reporter on his way out, Sam chats with Tom, and brings up Chris, his boyfriend who had been raped and murdered almost a year ago, supposedly by a man named Steve Warner. Sam goes home, and after masturbating he is taunted over the phone by Kenny's rapist, who then attacks him. Sam fights off his assailant, and accuses Brian of being him, as he showed up right after the attack, cellular phone in hand. Brian is arrested by Derek, but is released the next day, due to a lack of evidence, and Sam getting another call from the rapist.
