  1. Hi guys, Food and clams have been taken. Yumas are still reserved, but did not hear from the person. If I don't hear from him tomorrow I'll let it go to the next interested person. Rocks are reserved. Star polyps and hairy mushrooms available. Frag of yellow sun coral going at $8. PL lights still available. PM me if anyone's interested.
  2. Hi AT, Heh... ...it really has been awhile, hasn't it. Nothing happened lar...life happened...hahaha...got married (ROMed lar but it's as good as married), bought a new flat, bought my ride, got a new job...all within 2 months.. . In fact I'm starting out at the new place next week already. I figured, you know, don't think I'll have the time to spend on the tank to maintain it, water changes and monitoring, so thought, argh, let it go first... ...I can always start out again when things aren't so hectic anymore. But wa...letting go of the tank quite heart ache...like break up with gf like that... Diving also has taken a back seat for now lar, last trip was Manado as you probably remember. Supposed to go for a Redang trip or any trip with kelstorm, but with the upcoming flat, I figure better put some attention to it... ...so we going to aim for Bali next June...hopefully that materialises...
  3. Hi guys, For those who are coming to my place tonight, I arranged with you earlier today to come after 630pm, some of you were mentioning 7-8pm. Um...now change timing abit hor, gotta go pick up my wife. I'll only be back 9pm, so meeting can only take place after that, say about 930pm ok? I've already sent out the PMs earlier, I'm just posting here just in case you didn't see it. Just drop me a msg when you're nearby, so I can update you on my status lar ok?
  4. Hi guys, Rock is reserved. Vincent, the PL I believe is 1x36w daylight, 2x18W 50/50 and the last one I'm not too sure what it is but it isn't blue lar. I'm letting go the PL and their timers for $80 if anyone's interested.
  5. Hi Guys, Yumas are reserved. Hi Vincent, PL is for 3ft...hey I'll post more details later in the afternoon ok...I rushing off for lunch now...will tell you more later...sorry...
  6. Hi Guys, Food has been reserved. I've got live rock remaining. There's some cyano on it, but some scrubbing will take care of it. I'll price that at $5 a kg. I don't have a weighing scale, but I'll make it worth your while if you're a serious buyer. I don't have much rock, I'd estimate it as 40-50kg. Best if you can take everything. Some orange yumas (14 pieces) going for $20 as well. A piece of star polyps going for $20. Oh ya, forgot to mention , have some green hairy mushrooms as well, that will go for $15. My PL lights will be up next, once the corals have been taken care of.
  7. Hi guys, Clams reserved. Hi Sam, the yumas are fire orange, but they look less orangy under my lighting. But they've been in my tank for at least three months already. PM me if you're interested, ya? I've a camera phone, but trust me, the colour will look washed out if I take pics with it.
  8. Hi everyone, I have not been visiting SRC for a very long long time. Too many things happening in my life right now.. ...and it is with a heavy heart that I've decided to let go of my tank. Sales will go slow for the moment, so that I can organise what sequence of items can be sold first. First up will be some homemade food I bought from henry before. I had bought the $50 pack from him last time, barely used at all, sold part of it before as well. I'd like to sell my remaining amount for $25. It's quite a lot, so I think $25 is a good price. I'll throw in my remaining mysis packs and dry food as well. I've also got some live rock to clear. There's some cyano on it, but some scrubbing will take care of it. I'll price that at $5 a kg. I don't have a weighing scale, but I'll make it worth your while if you're a serious buyer. I don't have much rock, I'd estimate it as 40-50kg. Best if you can take everything. Got two clams, one green and the other purple, nothing fancy, going for $20 each. Some orange yumas (14 pieces) going for $20 as well. A piece of star polyps going for $20. I've got no cam, so no pictures. (my cam died) Self collect in Punggol after office hours. PM me for my address and number. That's all for now, after I've cleared this, I'll put some more up for sale. Thanks.
  9. here's another story you can all laugh at..hahaha... sometime last year, went to parkway parade. on the way up to the car park, I saw a BMW that had mounted the low concrete divider that separates the up-lane into the carpark and the down-lane from the carpark! the car was balanced on its undercarriage along its length! and in it was a little boy... HAHAHAHA!!! the cars on the way up and down had to drive a little slower and closer to their respective sides to avoid the beemer. on the way up I saw a woman talking rather dejectedly on the phone on the grass patch next to the up-lane...*laugh*...and in my rear view mirror? the tow truck. *snicker*
  10. hmm...will try to see if I can distinguish it that way...but they look really really similar ley.. my tank too small to have 5 inside lar...haha...I just bought two only...if and when I finally figure out how to ###### them, I might trade one if I find I have two of the same gender. I was at the shop the other day looking at the show tank which had 5(I think) pyjamas in there...tried looking at the dorsal fin (for banggais the male has a longer dorsal fin), but all of them had roughly similar lengths of dorsal fins so I guess that may not be a reliable way.
  11. Just out of curiosity...does anyone know how to ###### the pyjama cardinal? Would it be similar to the Banggai or are there other attributes?
  12. no no no... ...those coming out from the rear end are the hydrogen bombs! (Actually more like methane, but explosive all the same kekeke..) 50 Megaton rating. you have been warned.
  13. I got some clarification from the net: Uranium bomb The nuclear bomb that destroyed Hiroshima was a “gun” type bomb. By this I mean that a piece of U-235 was shot by a cannon at another piece of U-235; the combination was above the critical mass. The entire bomb, including cannon, weighed 4 tons. The energy release from the chain reaction was 13 kilotons of TNT equivalent. The day after Hiroshima was destroyed, President Harry Truman mistakenly announced the yield was 20 kilotons. This was the first uranium device ever exploded. It had not been tested. (The Alamogordo test was of a plutonium bomb.) The design was so simple that a test was decided to be a waste of uranium. After the bomb was dropped, there was not yet enough new uranium to make a new one, although the Oak Ridge plants were producing enough that a new bomb could be ready soon. Plutonium bomb are more difficult (see next section). For that reason, a bomb that uses uranium is the material of choice for a terrorist, since the design is so simple. But such a bomb requires highly enriched U-235, and that is not easy to make. When you dig uranium from the ground, it is 99.3% U-238, and only 0.7% U-235. It is only the rare isotope U-235 that can be used for a bomb. Separating this isotope is extremely difficult to do. When the United States defeated Iraq in 1991, one of the conditions that Saddam Hussein agreed to was inspections of his nuclear facilities. The U.S. discovered that he had developed devices to separate U-235 from natural uranium. But these devices, in stead of being the modern centrifuge or laser systems that we had anticipated, were Calutrons. This is short for "California utron", and it was the slow but sure method invented by Ernest Lawrence (after whom is named the Lawrence Berkeley Laboratory). Lawrence had invented this method during World War II, and his system had separated virtually all the U-235 that was used in the attack on Hiroshima. Prior to the Hiroshima attack, a nuclear weapon had been tested in Alamogordo, New Mexico. That was the first nuclear explosion. But the Alamogordo test did not use U-235. It used an isotope of plutonium, Pu-239. Plutonium bomb The bomb tested at Alamogordo, and the one dropped on Nagasaki, were both plutonium bombs, using Pu-239. Plutonium is relatively easy to get: it is produced in most nuclear reactors, including those intended to produce electric power, and then it can be separated using chemistry. However it normally has a high component of Pu-240, which is highly radioactive. This radioactivity tends to pre-detonate the bomb, i.e. make it explode before the chain reaction is complete. As a result, a special design had to be used: implosion. This is extremely difficult to design and engineer and build, and probably could not be built by a small organization such as a terrorist group. The resources of a full country (Pakistan, North Korea) are probably necessary. The bomb dropped on Nagasaki yielded 20 kilotons of explosion. It used only 6 kg of plutonium (about 13.5 pounds). That much plutonium could easily fit in a coffee cup. The higher yield per gram (compared to uranium) results from the fact that plutonium emits more neutrons in fission than does uranium, so the reaction goes faster, and we get a more complete chain reaction before the plutonium is blown apart. The plutonium is often arranged as a hollow shell, with explosives on the outside. The explosives drive the shell into a little blob, and compress it (even though it is solid). The compression pushes the atoms close enough together that neutrons produced in the chain reaction are unlikely to be able to leak in between them. Thus compressed plutonium has a smaller critical mass than uncompressed plutonium. The explosives often use a special kind of explosive "lens" (a special shape in the explosive that tends to make the explosion converge on a point). According to the chief nuclear weapons designer of Saddam Hussein, a U.S. trained physicist named Khidhir Hamza, the Iraqi bomb was not going to be a gun-style design. Instead, they would use uranium, but do an implosion in order to reduce the critical mass.[19] Thermonuclear weapon or "Hydrogen Bomb" In the hydrogen bomb, deuterium and tritium are heated by a plutonium or uranium fission bomb, to the point where they overcome their natural repulsion (the nuclei of both are positively charged) and fuse. This releases energy, and neutrons. The high energy neutrons cause fission in a uranium case (usually just U-238), and that releases even more energy. The biggest hydrogen bomb ever tested (they have never been used in war) released an energy over 50 million tons of TNT. That is million, not thousand! The "secret" of the hydrogen bomb, kept highly classified until just a few years ago, is that the plutonium bomb emits enough x-rays that they can be used, after bouncing off the uranium cases, to compress and ignite the tritium/deuterium combination. There is a second secret, although this has been public for a longer period. Instead of using tritium, the bomb can contain a stable (not radioactive) isotope of lithium called Li-6. This is a solid, which means that the material is stored at high density. The neutrons from the fission weapon break up the Li-6 to make the tritium. Thus the fuel is created in the same microsecond that the bomb is exploding. The fusion fuel is usually lithium combined with deuterium, called lithium deuteride.
  14. A bomb that uses the energy of the nucleus to release energy can safely be called a “nuclear bomb.” President Harry Truman referred to the bombs dropped over Japan as “Atomic bombs.” This name is still used. The bomb based on fusion of hydrogen is often referred to as a “hydrogen bomb.” A name typically used by scientists is “thermonuclear bomb.” The word thermonuclear refers to the fact that the fusion takes place because of the high temperature (that’s the thermo part).
  15. no lar...I didn't write this myself...pulled this off the net. but I've read this stuff before and somehow after reading about the destructive effects in the various zones, the info just kinda sticks. I never forgot about this...damn scary...*shudder*
  16. Anyone out there still thinks it's beautiful?
  17. Breakdown of the Blast Zones [1] Vaporization Point (Crater) Everything is vaporized by the blast. [2] Total Destruction All structures above ground are destroyed. [3] Severe Blast Damage Factories and other large-scale buildings collapse. Severe damage to highway bridges. Rivers sometimes flow counter-current. [4] Severe Heat Damage Everything flammable burns. People in the area suffocate due to the fact that most available oxygen is consumed by the fires. [5] Severe Fire & Wind Damage Residency structures are severely damaged. People are blown around. 2nd and 3rd-degree burns suffered by most survivors.
  18. Side Affects of the Nuclear Explosion Radiation The electromagnetic spectrum consists of cosmic rays, gamma rays, x-rays, ultraviolet rays, visible light rays, infrared rays, and radio rays. Of these, gamma rays are of chief concern to us. Gamma rays, alpha and beta particles, and neutrons result from decay of radioactive substances, and all four are emitted following a nuclear explosion. Their effects are all referred to below as radiation. When ionizing radiation enters the body, some of it is absorbed. This ionizes molecules in some of the body's cells, producing chemical changes so they cease to function. What is called "radiation sickness" may then occur. Fallout With surface explosions, or at altitudes low enough for the fireball to touch the ground, huge quantities of earth and debris, together with the fission products, are sucked into the fireball. As the fireball cools, the radioactivity condenses on the particles that were lifted from the ground; many of these are large particles and they come down by the force of gravity within a day, or, at distances not too far from the burst, some hundreds of kilometers. This constitutes the "local" or "early" fallout. The extent and location of the early fallout depends primarily on the meteorological conditions, e.g. the velocity and direction of the wind. They also depend on precipitation conditions; the particles may come down to earth with the rain or snow, which is referred to as "rainout" or "snowout". In addition to surface bursts and air bursts, underwater bursts occur at times. Radioactive fission products would mainly be absorbed by the water. However, some would escape to produce radioactive materials carried in a cloud of fog/spray which could drift in over land, adding to the exposure. It should be noted that all nuclear weapons detonated in the air give rise to fallout, but where and when it occurs depends primarily on the altitude of the explosion. With explosions in the air at altitudes such that the fireball does not touch the ground, the fission products, which are initially in gaseous form, rise with the fireball to great heights into the troposphere or stratosphere. When the temperature of the fireball becomes sufficiently low, the radioactive materials form particles, through condensation and coagulation. These particles are very small, and as a result their descent is very slow; it may take many months before they come down to the ground. EMP (Electro-magnetic Pulse) This is a byproduct of the immediate energy release from a detonated nuclear device which, as well as the other effects mentioned above, also has the effect of altering the electrical properties of electrons in the nearby atmosphere. This can produce intense electrical and magnetic fields that can extend for considerable distances from the point of detonation. The resultant electrical current eddies which pass through these disturbed electrical fields give rise to the EMPs that can, by themselves, produce so much energy that they can severely affect electronic-based equipment and electrical and radar transmissions to the point of destroying equipment circuits, components and communications. The effects of EMP diminish sharply with distance from the point of detonation but can still cause damage at ranges greater than those for the other 3 major effects (under certain circumstances). Their main significance will be to communications; the communications networks will probably be rendered inoperative for considerable periods of time by interference from EMPs, and the results of such breakdowns can well be imagined. At the very moment when radio and other links (including land lines) between various command levels are at their most important the EMPs will render them virtually useless over large areas. Even when a nuclear explosion has passed, the reverberations produced by the EMP in the atmosphere may well linger to cause continued interruptions. Heavy concentrations of fallout will produce radiation to create further interference across radio and other communication frequencies. Mass Fires There are two types of mass fires - the conflagration and the firestorm. Both are created from the hundreds of individual fires that are started as a result of the nuclear blast. Conflagration Fire The conflagration is a large-area fire which is moved by a strong wind, devouring everything in its path. The wind causes a literal wall of flame to form and to move before it. This type of mass fire can be expected to occur in many forests and in dry grassy areas. If you consider the damage done over the last few years by brush and forest fires in California, you can begin to understand the destruction that would be caused by hundreds of such fires massing together. Firestorm The firestorm is a mass fire that burns intensely in one area. As the many smaller fires burn, they cause air to be pulled into the area, and smoke and superhot gases then escape upward. Once this airflow pattern begins, it feeds on itself, creating a sort of a chimney effect. Once the phenomenon is fully developed the air flows into the area at between 80 and 115 kilometers per hour. Temperatures reach as high as 1000 to 2000 degrees Fahrenheit, so even things that aren't actually touched by flames are consumed and destroyed. Unlike the conflagration, a firestorm doesn't travel; it moves little, if at all, due the strong winds blowing in from all sides. A firestorm can form in an area of many smaller fires in about 15 to 20 minuets and may last anywhere from 3 to 8 hours. Many parts of the area may remain too hot to enter for a couple of days after the fires have burned themselves out.
  19. A Nuclear Explosion When a nuclear weapon explodes, in about a millionth of a second a temperature of up to eighteen million degrees Fahrenheit, comparable to that inside the sun, is produced. About half of this is immediately lost in the close vicinity of the explosion as a luminous white fireball appears, expands and begins to rise. For up to a minute, energy in the forms of radiation, EMP (electromagnetic pulse), light, heat, sound, and blast is released in all directions. The fireball then ceases to be luminous and begins to cool as its cloud rises many thousands of meters at up to 480 kilometers per hour. As the cloud billows out into its eventual mushroom shape it sucks up after it a column of dust from the earth's surface. This dust mixes with residue of the weapon and becomes radioactive fallout. Components of the Nuclear Explosion Light This is largely ultraviolet and infrared, more intense than it appears to be, and liable to cause blindness, even though sight may return within a few days. Heat One third of the energy of a nuclear weapon is emitted in this form. It radiates in straight lines at the velocity of light, but has little penetrating power and is weakened by haze or mist. Its range, however, is greater than that of blast or of initial radiation, and it may cause injury or death to those exposed and damage to property by starting fires. Blast A wave of compressed air moves away from the site of a nuclear explosion at about the speed of sound. Lasting several seconds, it maintains pressure upon objects in its path in a manner more usually associated with a very high wind than the shock wave of an explosion. It is the main cause of damage to buildings, and a hazard to those outside or within. A wave of air rushes back in to fill the void seconds after the initial blast wave passes. This wave is not as strong, maybe several hundred kilometers per hour.
