Heroin, or diacetylmorphine, also known as diamorphine, is a semi-synthetic opioid drug synthesized from morphine, a derivative of the opium poppy. As with other opioids, heroin is used as both an analgesic and a recreational drug. Frequent and regular administration is associated with tolerance and physical dependence, which may develop into addiction. Internationally, heroin is controlled under Schedules I and IV of the Single Convention on Narcotic Drugs. It is illegal to manufacture, possess, or sell diacetylmorphine without a license in Belgium, Denmark, Germany, Iran, India, the Netherlands, the United States, Australia, Canada, Ireland, Pakistan, the United Kingdom and Swaziland. Under the name diamorphine, it is a legally prescribed controlled drug in the United Kingdom. It is available for prescription to long-term users in the Netherlands, United Kingdom, Switzerland, Germany and Denmark alongside psycho-social care, and a similar program is being campaigned for by liberal political parties in Norway. Some countries allow the government to sell or donate high-quality seizures of drugs and precursors which are otherwise legal for medicinal use to pharmaceutical manufacturers for use in preparing licit supplies of medical drugs and research chemicals; this was the case in Croatia prior to 2007. The onset of diacetylmorphine's effects depends upon the route of administration. Studies have shown that the subjective pleasure of drug use (the reinforcing component of addiction) is proportional to the rate at which the blood level of the drug increases. Intravenous injection provides the fastest and most intense rush within seven to eight seconds. Intra-muscular injection produces a relatively slow onset of five to eight minutes. Snorting or smoking reaches peak effects within 10 to 15 minutes. If taken orally, the effects take approximately half an hour to set in, with an absence of a rush. Large doses of heroin can cause fatal respiratory depression, and the drug has been used for suicide or as a murder weapon. The withdrawal syndrome from heroin (the so-called cold turkey) may begin within 6 to 24 hours of discontinuation of the drug; however, this time frame can fluctuate with the degree of tolerance as well as the amount of the last consumed dose. Symptoms may include: sweating, malaise, anxiety, depression, priapism, extra sensitivity of the genitals in females, general feeling of heaviness, cramp-like pains in the limbs, excessive yawning or sneezing, tears, rhinorrhea, sleep difficulties (insomnia), cold sweats, chills, severe muscle and bone aches; nausea and vomiting, diarrhea, cramps, and fever.

Gemini 9A (officially Gemini IX-A) was a 1966 manned spaceflight in NASA's Gemini program. It was the 7th manned Gemini flight, the 13th manned American flight and the 23rd spaceflight of all time (includes X-15 flights over 100 km). One of the mission objectives was to dock with an Agena Target Vehicle in the same manner as the Gemini 8 mission. However, during the launch of the Gemini 9 Agena on May 17, 1966, its Atlas booster malfunctioned like it had on Gemini 6A, and it failed to make it to orbit. The first launch attempt of Gemini 9A was on June 1. The ATDA had launched perfectly into a 298 kilometre orbit, though telemetry from it indicated that the launch shroud had failed to open properly. But the Gemini spacecraft was not able to launch the same day as planned. At T-3 minutes, the ground computers could not contact the Gemini computers for some reason and the 40 second launch window opened and closed without the launch. This earned Tom Stafford the title of "Mayor of Pad 19." The second launch attempt went perfectly with the spacecraft entering into orbit. With this launch, Stafford could say that he had been strapped into a spacecraft six times ready for launch. Their first burn was 49 minutes after launch. They added 22.7 metres per second to their speed which put them in a 160 to 232 kilometres orbit. Their next burn was designed to correct phase, height, and out-of-plane errors. They pointed the spacecraft 40° down, and 3° to the 'left'. The burn added 16.2 metres per second to their speed and put them in a 274 by 276 kilometres orbit, closing at 38 metres per second on the ATDA. The first radar readings were when they were 240 km away and they had a solid lock at 222 km. Their first sight came 3 hours and 20 minutes into the mission when they were 93 km away. They noted that they could see the flashing lights on the ATDA designed to aid identification from a distance. This made them hope that the launch shroud had in fact been jettisoned and that the telemetry was wrong. As they got closer they found that in fact the shroud had half come off. Stafford described "It looks like an angry alligator out here rotating around". He asked if maybe he could use the spacecraft to open the 'jaws' but the ground decided against it. ATDA, a.k.a. the "Angry Alligator", as seen from Gemini 9The crew described how the shroud's explosive bolts had fired, but two neatly taped lanyards were holding the shroud together. It was decided that it would be too dangerous for an astronaut to cut the lines, as there were too many sharp edges around. The reason for the lanyards was soon discovered. Douglas built the shroud, but Lockheed attached it to the rocket, while McDonnell built the ATDA. A Douglas engineer had made a practice run with the McDonnell crew but didn't give them instructions on the final procedures which involved the lanyards. The McDonnell crew had the Douglas instructions for this procedure which said, "See blueprint", but there was no blueprint. So the McDonnell technicians decided to tape down the loose lanyards as it seemed like the sensible thing to do. On their 45th revolution of the Earth, they fired the retrofire rockets that slowed them down so that they would reenter. This time the computer worked perfectly, meaning they landed only 700 metres from the planned landing site and were close enough to see the prime recovery ship, the USS Wasp. The splashdown happened closer to the recovery ship than any other manned American spacecraft. [READ THE REST OF THIS ARTICLE]



The Enforcement Droid Series 209, or ED-209, is a fictional robot in the RoboCop franchise. The ED-209 serves as a heavily-armed obstacle and foil for the series' titular character, as well as a source of comic relief due to its lack of intelligence and tendency to malfunction. The ED-209 was designed by Craig Davies, who also built the full size models, and animated by Phil Tippett, a veteran stop-motion animator. Davies and Tippett would go on to collaborate on many more projects. As one of the setpieces of the movie, the ED-209’s look and animated sequences were under the close supervision of director Paul Verhoeven, who sometimes acted out the robot's movements himself. Director Paul Verhoeven made it clear very early on that ED-209 should not look “cute.” He wanted the robot to look hard and mean. For this reason, various common robot features were left out. There are no eyes on the ED-209, for instance, since Craig Davies believed they conveyed too much emotion as well as being clichéd. According to RoboCop writer Ed Neumeier, the ED-209 robot was designed to resemble a bipedal Vietnam War-era Huey helicopter. The rear-facing knee joints make ED-209 a so-called chicken walker. Craig Hayes (then Davies) also incorporated his ideas about modern 1980s American design, especially car design, into the robot. He envisioned futuristic designers making the robot look good in order to make it marketable before they made it work well, “just like an American car.” The crew commentary audio track on the Criterion Collection DVD release confirms the obvious commentary on ridiculous corporate design policies, with such features as an obviously over-designed hydraulic system, over-attention paid to cosmetics and the placement of obviously vulnerable features such as the radiator grill on the very front of the robot. ED-209 is primarily featured in the first film, where it appears three times. The 209 series was an attempt to create a series of law enforcement robots, the brain child of the movie’s main villain, OCP Senior President Dick Jones. During a demonstration of the ED-209's offensive capabilities to the OCP board, it malfunctions and brutally kills an OCP executive, Kinney - even though he had complied with the robot’s orders to “surrender” and put down his gun, ED-209 appears incapable of recognising this fact. (Why this demonstration model is loaded with live ammunition on this occasion is unexplained, and could simply be a plot device). Because of this disastrous malfunction, the RoboCop program is given the green light. [READ THE REST OF THIS ARTICLE]



Cauliflower ear (also hematoma auris, perichondrial hematoma, and Traumatic auricular hematoma) is a condition most common among boxers, amateur wrestlers, professional wrestlers, rugby players, and mixed martial artists. If the external portion of the ear suffers a blow, a blood clot or other fluid may collect under the perichondrium. This separates the cartilage from the overlying perichondrium that is its source of nutrients, causing the cartilage to die. This leads to a formation of fibrous tissue in the overlying skin. When this happens, the outer ear becomes permanently swollen and deformed, resembling a cauliflower. Headgear that protects the ears is worn in wrestling and rugby (where it is called a "scrum cap"), many martial arts, and other contact sports to help prevent this condition. For some wrestlers and fighters, however, a cauliflower ear is considered a badge of courage or experience. Fluid collection in the outer ear can be treated by draining the fluid and applying a compressing tie to the outer ear to reconnect the perichondrium and the cartilage. The compressing tie will be left in place for around 9 days to prevent the fluid from building up again. The outer ear is prone to infections, so antibiotics are usually prescribed. If the pressure is left alone without medical intervention, the ear can suffer serious damage. Pressure can build up and eventually rupture the ear drum. When this occurs, the ear may further wrinkle, and can become slightly pale; hence the common term "cauliflower ear". Should the ear drum rupture, the only treatment option is to heal the existing wound with stitches. Even with treatment, significant hearing loss may occur. Cosmetic procedures are available which can greatly improve the appearance of the ear, even though internal damage may persist. [READ THE REST OF THIS ARTICLE]
