The Chinese cobra is a very alert, seldom cornered, but if confronted will raise its forebody and spread its hood and strike readily if necessary. Adults can be very aggressive, but the younger tend to be more aggressive. The Chinese cobra usually escapes to avoid confrontation with humans, but strikes readily if provoked. The snake is terrestrial, diurnal and crepuscular which means it is active by day and twilight. This species has been observed hunting during all daylight periods and as late as 2–3 hours after sunset from March to October, with ambient temperatures of 20–32°C (68–90°F).
The Chinese Cobra has a widely varied diet and it mainly preys on rodents such as mice and rats, frogs, toads and even other snakes. It is active during both the day and night. The diet of this snake is highly variable. It preys on any vertebrates from fish to mammals. Juveniles eat mosly amphibians, whereas adults usually prefer reptiles and mammals - during amphibian breeding periods, however, adult cobras eat mostly frogs or toads: the Cricket frog ("Fejervarya limnocharis"), the Common tree frog ("Polypedates leucomystax"), and the Asian common toad ("Duttaphrynus melanostictus").
It is oviparous. Mating and egg-laying periods are very extended. The species has been observed mating in the mountains of the western Tonkin region, at elevations of in the months of March through May. As recorded, gravid females will lay between 6 and 23 eggs sometime between May through to the end of July.
The Chinese cobra is a highly venomous member of the true cobras (genus "Naja"). Its venom consists mainly of postsynaptic neurotoxins and cardiotoxins. Four cardiotoxin-analogues I, II, III, and IV, account for about 54% of the dry weight of the crude venom and have cytotoxic properties. The LD values of its venom in mice are 0.29 mg/kg IV, and a range of 0.53 mg/kg - 0.67 mg/kg SC. The average venom yield from a snake of this species kept at a snake farm was about 250.8 mg (80 mg dry weight). Although this is not a spitting cobra, some rare individuals (mostly specimens from Guizhou Province) are capable of ejecting venom towards a threat within a distance of .
Local symptoms in victims caused by Chinese cobra are wound darkening, localized redness and swelling, pain, insensibility, and invariably blisters and necrosis. Necrosis is a serious problem in cases of cobra bite as it may persist for many years after the general recovery of the victim. The following systemic symptoms may also occur: chest discomfort, fever, sore throat, difficulty in swallowing, loss of voice, weak feeling in limbs, walking haltingly, general ache, lockjaw, and difficulty in breathing. Fatality occasionally occurs. The antivenom is widely available and deaths are much rarer than they used to be.
Robots exclusion standard
The robots exclusion standard (also called the robots exclusion protocol or robots.txt protocol) is a way of telling Web crawlers and other Web robots which parts of a Web site they can see.
To give robots instructions about which pages of a Web site they can access, site owners put a text file called robots.txt in the main directory of their Web site, e.g. <nowiki>http://www.example.com/robots.txt</nowiki>. This text file tells robots which parts of the site they can and cannot access. However, robots can ignore robots.txt files, especially malicious (bad) robots. If the robots.txt file does not exist, Web robots assume that they can see all parts of the site.
VHF omnidirectional range
VOR, short for VHF omnidirectional radio range, is a type of radio navigation system for aircraft, enabling them to find their position and stay on course by receiving radio signals emitted by a network of radio beacons. It uses frequencies in very high frequency (VHF) from 108 to 117.95 MHz. Developed in the USA in 1937, VOR is the standard air navigational system in the world, used by both commercial and general aviation. There are about 3000 VOR stations around the world.
A VOR station broadcasts a VHF radio signal including the identifier, voice, and navigation signal. The identifier is in Morse Code. The voice will have information from the station. The navigation signal allows the equipment to find a magnetic bearing from the station to the aircraft. VOR stations in areas of magnetic unreliability are oriented to True North. A line of position is called the "radial" from the VOR. The crossing of two radials from different VOR stations provides the position of the aircraft. VOR signals have a range of about 200 miles.

The Conqueror Worm
"The Conqueror Worm" is a poem by Edgar Allan Poe. It is about human mortality and the fact that death cannot be stopped. It was first published in "Graham's Magazine" in 1843. It was incorporated into Poe's short story "Ligeia" in 1845. In the revised story, the poem is composed by Ligeia. She teaches it to the narrator during her death throes.
Weeping angels watch a play performed by "mimes, in the form of God on high", and controlled by vast formless shapes looming behind the scenes. The mimes chase a "Phantom" which they can never capture. Finally, a monstrous "crawling shape" emerges, and eats the mimes. The final curtain comes down, "a funeral pall," signaling an end to the "tragedy, 'Man'" whose only hero is "The Conqueror Worm".
Though Poe was referring to an ancient connection between worms and death, he may have been inspired by "The Proud Ladye", a poem by Spencer Wallis Cone which was reviewed in an 1840 issue of "Burton's Gentleman's Magazine". That poem contained the lines "Let him meet the conqueror worm / With his good sword by his side".
The poem plays an important symbolic role as part "Ligeia." The poem is written by Ligeia as she is dying, though it is actually recited by the narrator, her husband.
Because it emphasizes the finality of death, it calls to question Ligeia's resurrection in the story. Also, the inclusion of the bitter poem may have been meant to be ironic or a parody of the convention at the time, both in literature and in life. In the mid-19th century it was common to emphasize the sacredness of death and the beauty of dying (consider Charles Dickens's Little Johnny character in "Our Mutual Friend" and the death of Helen Burns in Charlotte Brontë's "Jane Eyre"). Instead, Ligeia speaks of fear personified in the "blood-red thing."
"The Conqueror Worm" also uses the word "evermore", which would later evolve into "nevermore" in Poe's famous poem "The Raven" in 1845.
"The Conqueror Worm" was first published as a stand-alone poem in the January 1843 issue of "Graham's Magazine". Shortly after, it was included among several other poems by Poe in the February 25 issue of the "Saturday Museum" in a feature called "The Poets & Poetry of Philadelphia: Edgar Allan Poe". It was later included in Poe's poetry collection "The Raven and Other Poems" in 1845. That same year, it was incorporated into "Ligeia" for the first time when the story was reprinted in the February 15, 1845, issue of the "New York World". "Ligeia" was again republished with "The Conqueror Worm" in the September 27, 1845, issue of "The Broadway Journal" while Poe was its editor. This was not unusual for Poe, who had also incorporated poems "The Coliseum" and "To One in Paradise" into tales.
The British horror movie "Witchfinder General" was retitled "The Conqueror Worm" for US release. It was not based on Poe's poem.
