Oxygen Cylinder Quotes

And then I found myself atop a slender wedge of ice, adorned with a discarded oxygen cylinder and a battered aluminum survey pole, with nowhere higher to climb. A string of Buddhist prayer flags snapped furiously in the wind. Far below, down a side of the mountain I had never laid eyes on, the dry Tibetan plateau stretched to the horizon as a boundless expanse of dun-colored earth.

Plodding slowly up the last few steps to the summit, I had the sensation of being underwater, of life moving at quarter speed. And then I found myself atop a slender wedge of ice, adorned with a discarded oxygen cylinder and a battered aluminum survey pole, with nowhere higher to climb. A string of Buddhist prayer flags snapped furiously in the wind. Far below, down a side of the mountain I had never laid eyes on, the dry Tibetan plateau stretched to the horizon as a boundless expanse of dun-colored earth.

In the face of the calamity, the Modi government froze. In the seven months from March to September 2020, Modi made 82 public appearances—physical as well as virtual. In the next four months, he made 111 such appearances. From February to 25 April 2021, he clocked 92 public appearances. From 25 April, after he called off the Kumbh and his Bengal rallies, Modi disappeared. He made no public appearance for 20 days.147 The prime minister of India fled the field when his people needed the government most. Through all of April and much of May, upper class Indians flooded Twitter with calls for help to find hospital beds, oxygen cylinders, drugs like Remdesivir and ventilators.148 The Union did not think to set up a helpline to guide those who needed this help. Into this space strode the youth Congress leader B.V. Srinivas (@srinivasiyc) who, with a team of volunteers, began to help people reaching out for aid on Twitter. He was so effective in the absence of the State and any government presence that even the embassies of New Zealand and the Philippines contacted him for help when staffers fell ill with Covid.149 Focussed on the government’s image, Jaishankar tweeted: ‘This was an unsolicited supply as they had no Covid cases. Clearly for cheap publicity by you know who. Giving away cylinders like this when there are people in desperate need of oxygen is simply appalling.’ The New Zealand embassy staffer who had received oxygen from Srinivas on 2 May died 18 days later.

You are God. You want to make a forest, something to hold the soil, lock up energy, and give off oxygen. Wouldn’t it be simpler just to rough in a slab of chemicals, a green acre of goo? You are a man, a retired railroad worker who makes replicas as a hobby. You decide to make a replica of one tree, the longleaf pine your great-grandfather planted- just a replica- it doesn’t have to work. How are you going to do it? How long do you think you might live, how good is your glue? For one thing, you are going to have to dig a hole and stick your replica trunk halfway to China if you want the thing to stand up. Because you will have to work fairly big; if your replica is too small, you’ll be unable to handle the slender, three-sided needles, affix them in clusters of three in fascicles, and attach those laden fascicles to flexible twigs. The twigs themselves must be covered by “many silvery-white, fringed, long-spreading scales.” Are your pine cones’ scales “thin, flat, rounded at the apex?” When you loose the lashed copper wire trussing the limbs to the trunk, the whole tree collapses like an umbrella. You are a sculptor. You climb a great ladder; you pour grease all over a growing longleaf pine. Next, you build a hollow cylinder around the entire pine…and pour wet plaster over and inside the pine. Now open the walls, split the plaster, saw down the tree, remove it, discard, and your intricate sculpture is ready: this is the shape of part of the air. You are a chloroplast moving in water heaved one hundred feet above ground. Hydrogen, carbon, oxygen, nitrogen in a ring around magnesium…you are evolution; you have only begun to make trees. You are god- are you tired? Finished?

May I ask you a question? If you have to hold your breath too long, what is it that makes you desperate to breathe again?” “I’m running out of oxygen, I guess.” “That’s the interesting fact. It isn’t the absence of oxygen. It’s the presence of carbon dioxide. Kind of the same thing, but not exactly. The point is, you could suck up any kind of gas, and as long as it wasn’t carbon dioxide, your brain would be happy. You could have a chest full of nitrogen, no oxygen at all, about to kill you stone dead, and your lungs would say, hey man, we’re cool, no carbon dioxide here, no need for us to start pumping again until we see some. Which they never will, because you’ll never breathe again. Because you’ll never need to. Because you have no carbon dioxide. And so on. So those folks started sniffing nitrogen, but you have to go to the welding shop and the cylinders are too heavy to lift, so then they tried helium from the balloon store, but you needed masks and tubes, and the whole thing still looks weird, so in the end most folks won’t be satisfied with anything less than the old-fashioned bottle of pills and the glass of scotch. Exactly like it used to be. Except it can’t be anymore. Those pills were most likely either Nembutal or Seconal, and both of those substances are tightly controlled now. There’s no way to get them. Except illegally, of course, way down where no one can see you. There are sources. The holy grail. Most of the offers are scams, naturally. Powdered Nembutal from China, and so on. Dissolve in water or fruit juice. Maybe eight or nine hundred bucks for a lethal dose. Some poor desperate soul takes the cash to MoneyGram and sends it off, and then waits at home, anxious and tormented, and never sees any powdered Nembutal from China, because there never was any. The powder in the on-line photograph was talc, and the prescription bottle was for something else entirely. Which I felt was a new low, in the end. They’re preying on the last hopes of suicidal people.

Working on the summit of Mauna Kea was comparable to working on the hospital pulmonary ward with sick people sucking on oxygen cylinders.

When I was instructed to use medical oxygen to do my job at the W. M. Keck Observatory from 2001 to 2006, I was never told about the legal health information that is now posted on oxygen cylinders. My memories of the green medical oxygen cylinders that we would use daily is that they had no information on them and we were never given a recognised legal oxygen administration training course for routine daily use or a medical prescription from a doctor. We were shown the three oxygen cylinders at the facility and told to use them whenever we developed headaches, which was multiple times daily. It was common to find all three oxygen cylinders in use by other very high altitude workers and to have to line up to get a turn on the magical medical gas.

Stone went through two more corrections, and five sharp braking maneuvers. Then, maybe half a mile from the booster, he took the Apollo on a short, angular inspection sweep. The reaction control systems bit sharply, rattling York against her restraint. York watched the cluster roll with silent grace past her window. The booster cluster was squat, pregnant with fuel. Its heart was a fat MS-II booster, a Saturn second stage, modified to serve as an orbital injector. Fixed to the front of the MS-II was an MS-IVB, a modified Saturn third stage, a narrower cylinder. To either side of the MS-II were fixed the two External Tanks, fat, silvery cylinders as long and as wide as the MS-II stage itself. The supplementary tanks carried more than two million pounds of liquid oxygen and hydrogen, propellant Ares would need to break clear of Earth orbit. The MS-II and its tanks looked like three fat sausages, side by side, with the slimmer pencil shape of the MS-IVB protruding from the center. The rest of the Ares stack—the Mission Module, MEM, and Apollo—would be docked onto the front of the MS-IVB to complete the assembly of the first Mars ship, a needle well over three hundred feet long.

Schwieger ordered the submarine to the bottom so his crew could dine in peace. “And now,” said Zentner, “there was fresh fish, fried in butter, grilled in butter, sautéed in butter, all that we could eat.” These fish and their residual odors, however, could only have worsened the single most unpleasant aspect of U-boat life: the air within the boat. First there was the basal reek of three dozen men who never bathed, wore leather clothes that did not breathe, and shared one small lavatory. The toilet from time to time imparted to the boat the scent of a cholera hospital and could be flushed only when the U-boat was on the surface or at shallow depths, lest the undersea pressure blow material back into the vessel. This tended to happen to novice officers and crew, and was called a “U-boat baptism.” The odor of diesel fuel infiltrated all corners of the boat, ensuring that every cup of cocoa and piece of bread tasted of oil. Then came the fragrances that emanated from the kitchen long after meals were cooked, most notably that close cousin to male body odor, day-old fried onions. All this was made worse by a phenomenon unique to submarines that occurred while they were submerged. U-boats carried only limited amounts of oxygen, in cylinders, which injected air into the boat in a ratio that varied depending on the number of men aboard. Expended air was circulated over a potassium compound to cleanse it of carbonic acid, then reinjected into the boat’s atmosphere. Off-duty crew were encouraged to sleep because sleeping men consumed less oxygen. When deep underwater, the boat developed an interior atmosphere akin to that of a tropical swamp. The air became humid and dense to an unpleasant degree, this caused by the fact that heat generated by the men and by the still-hot diesel engines and the boat’s electrical apparatus warmed the hull. As the boat descended through ever colder waters, the contrast between the warm interior and cold exterior caused condensation, which soaked clothing and bred colonies of mold. Submarine crews called it “U-boat sweat.” It drew oil from the atmosphere and deposited it in coffee and soup, leaving a miniature oil slick. The longer the boat stayed submerged, the worse conditions became. Temperatures within could rise to over 100 degrees Fahrenheit. “You can have no conception of the atmosphere that is evolved by degrees under these circumstances,” wrote one commander, Paul Koenig, “nor of the hellish temperature which brews within the shell of steel.

There are numerous types of oxygen available for purchase. These are industrial oxygen – generally for welding and not suitable for human consumption, aviation oxygen – regulated by the FAA rules, medical oxygen - regulated by the FDA and DOT. It was unclear what type of oxygen was inside the oxygen cylinders that employees were using at the summit of Mauna Kea and most employees assumed it was medical oxygen for treating their medical conditions.

How could this be corrected? One way, Carnot argues, is to use atmospheric air as the substance that pushes the piston. Because air contains oxygen, fuel can burn and generate heat inside the cylinder and not in an external boiler as happens in a steam engine.
