![]() ![]() Milk of lime, Ca(OH) 2, reacts with elemental sulfur to give a " lime-sulfur", which has been used as an insecticide. Millions of tons of this calcium sulfide byproduct was discarded, causing extensive pollution and controversy. In that process sodium sulfide reacts with calcium carbonate: Na 2S + CaCO 3 → CaS + Na 2CO 3 In the second reaction the sulfate (+6 oxidation state) oxidizes the sulfide (-2 oxidation state) to sulfur dioxide (+4 oxidation state), while it is being reduced to sulfur dioxide itself (+4 oxidation state).ĬaS is also a byproduct in the Leblanc process, a once major industrial process for producing sodium carbonate. In the crystal, each S 2− ion is surrounded by an octahedron of six Ca 2+ ions, and complementarily, each Ca 2+ ion surrounded by six S 2− ions.ĬaS is produced by "carbothermic reduction" of calcium sulfate, which entails the conversion of carbon, usually as charcoal, to carbon dioxide: The high melting point is also consistent with its description as an ionic solid. In terms of its atomic structure, CaS crystallizes in the same motif as sodium chloride indicating that the bonding in this material is highly ionic. Like many salts containing sulfide ions, CaS typically has an odour of H 2S, which results from small amount of this gas formed by hydrolysis of the salt. CaS has been studied as a component in a process that would recycle gypsum, a product of flue-gas desulfurization. This white material crystallizes in cubes like rock salt. Calcium sulfide is the chemical compound with the formula Ca S. ![]()

![]() That much the faltering wireless had told. Smith, the admiral of the White Star fleet, knew there was no hope of saving her. Through the plates and timbers water rushed so swiftly that her captain, E. From a happy, comfortable vessel she was converted in a few minutes into a bedlam of misery and dreadful suffering. Running at high speed into that grim and silent enemy of seafarers, the shock crushed her bow. On her maiden trip, the Titanic, built and equipped at a cost of $10,000,000, a floating palace, found her graveyard when swinging from the westerly steamship lane, south of the Grand Banks of Newfoundland, to take the direct run to this port, she hurled her giant bulk against an iceberg that rose from an immense field that drifted from the Arctic. The great ship was the last word in modern scientific construction, but she found the ocean floor almost as quickly as a wooden ship. The White Star line believed that the Titanic was practically invulnerable and insisted until there was no doubting the full extent of the catastrophe that she could not sink. on Sunday night, her fate established that no modern steamship is unsinkable, and that all of a large passenger list cannot be saved in a liner’s small boats. When the Titanic plunged headlong against a wall of ice at 10:40 p.m. The news that few besides the women and children were saved has caused the greatest apprehension to the fate of these. Stead, the London journalist, and many more whose names are known on both sides of the Atlantic. John Jacob Astor and his wife, Isidor Straus, Maj. Smith of the Titanic is believed to have gone to the bottom with his vessel.Īmong the 1,320 passengers of the giant liner were Col. The crew numbered 860, bringing the total of those known to be aboard up to 2,180, but it is understood that at the last minute before sailing several got aboard, making the total up to a full 2,200.Ĭapt. The numbers are enough to indicate that if the women and children were saved, very few men could have survived the disaster, as there were almost enough women and children aboard to make up the 675 survivors. In second cabin there were 285 persons, including 79 women and 8 children, and in the steerage the complement of 710 was divided almost equally, it is believed, between women and men, with a small percentage of children. There were 325 first cabin passengers on the Titanic, of whom 128 were women and 15 children. All night a crowd of anxious relatives and friends of the Titanic’s passengers were massed in front of the line’s offices at No. It is probable that these names will be received in the morning. Not a name of those saved had reached the offices of the White Star line or the Cunard line at midnight, though every effort was being made to get in communication with the vessel that bore the survivors. They were picked up from small boats by Cunarder Carapthia which found, when she ended her desperate race against time, a sea strewn with wreckage of the lost ship and bodies of drowned men and women. Out of nearly 2,200 persons that she carried only 673 were saved and most of these are women and children. NEW YORK, April 13 - The greatest marine disaster in the history of the world occurred last Sunday night when the Titanic, of the White Star Line, the biggest and finest of steamships, shattered herself against an iceberg and sank with 1,500 of her passengers and crew in less than four hours. ![]() ![]() ![]() Unlike the Sharpe Ratio, the Calmar Ratio cannot be scaled to different time horizons, so portfolios that use the Calmar Ratio should have the same backtesting period. Investors will generally use Calmar ratio in conjunction with Sharpe Ratio and Sterling Ratio. If the Calmar ratio is on a downtrend, it is important for investors to review their portfolio to find whether the decrease is because of increased volatility, decreased returns or some other factors.Ĭalmar ratio is also an important ratio calculated while backtesting trading strategies.

If you were climbing a 29000ft mountain peak and you fell down 2000 feet then the 2000 feet would be the equivalent of a drwadown. Maximum drawdown is defined as the maximum loss from a peak-to-trough during an investment period. Max Drawdowna loss in equity from a previous high. The period between the peak level and the trough is called the “length” of the drawdown.

Luckily, aside from having different masses, most other properties of different isotopes are similar. For most of our purposes in chemistry, we will do the same thing and deal with the average mass of the atoms. As a result, when he performed his measurements, he was actually observing the averaged properties of all the different isotopes in the sample. In a chunk of lithium, \(93\%\) will always be lithium with 4 neutrons, while the remaining \(7\%\) will always be lithium with 3 neutrons.ĭalton always experimented with large chunks of an element-chunks that contained all of the naturally occurring isotopes of that element. Moreover, it always contains the two in the same relative amounts (or "relative abundance"). In other words, a piece of lithium always contains both types of naturally occurring lithium (the type with 3 neutrons and the type with 4 neutrons). But if atoms of a given element can have different numbers of neutrons, then they can have different masses as well! How did Dalton miss this? It turns out that elements found in nature exist as constant uniform mixtures of their naturally occurring isotopes. According to Dalton, atoms of a given element are identical. This whole discussion of isotopes brings us back to Dalton's Atomic Theory. In contrast, the carbon isotopes called carbon-12 and carbon-13 are stable. The isotope of carbon known as carbon-14 is an example of a radioisotope. This is why radioactive isotopes are dangerous and why working with them requires special suits for protection. When they decay, they release particles that may be harmful. Many isotopes have radioactive nuclei, and these isotopes are referred to as radioisotopes. This process is called radioactive decay. Having too many or too few neutrons relative to protons results in an unstable, or radioactive, nucleus that will sooner or later break down to a more stable form. For instance, lithium exists as an isotope with 3 neutrons, and as an isotope with 4 neutrons, but it doesn't exist as an isotope with 2 neutrons or as an isotope with 5 neutrons.Ītoms need a certain ratio of neutrons to protons to have a stable nucleus. The mass number, however, is 6 in the isotope with 3 neutrons, and 7 in the isotope with 4 neutrons. Notice that because the lithium atom always has 3 protons, the atomic number for lithium is always 3. ![]() ![]() ![]() Serving: Chico Paradise Oroville Yuba City Auburn Colfax Lincoln Rocklin Roseville Loomis Citrus Heights Elk Grove Folsom Galt Isleton Rancho Cordova Sacramento PressureNet Preferred Pressure Washing ServiceĬhico Sacramento Paradise Magalia CA, CA 95969 make them part of your family when you learn they will always be there for you.California Pressure Washing Services Directoryīelow are the pressure washing companies currently listed Make them your friends when you first call them.

Pseudo-UTP, along with 5-methylcytidine-5'-triphosphate (5-methyl-CTP) has shown innate immune suppression in culture and in vivo while enhancing translation in recent publications. Pseudouridine-5'-triphosphate (Pseudo-UTP) is used to impart desirable mRNA characteristics such as increased nuclease stability, increased translation or altered interaction of innate immune receptors with in vitro transcribed RNA. Pseudouridine has been found to enhance base stacking and translation. It can be found in structural RNAs, such as transfer, ribosomal and small nuclear RNA.
