Phosphorus, Chemical Element

See How Foods Affect Sleep By Firas Kittaneh We all know nutrition provides our bodies with fuel for the day, but what we eat also affects how we power down at night. Research has found that certain nutrients in food can affect sleep, from how easy it is to fall asleep at a reasonable hour to the quality of rest we get throughout the night. See what you should munch on for better nights and what foods to skip. Dietary Habits and Your Sleep Have you ever caught yourself napping after a big meal or wishing you wouldn’t have had that post-dinner coffee? What we consume and when can affect our sleep in a variety of ways. One obvious avenue is by stimulating biological systems that keep us awake. Sugars, caffeine and other stimulants work on hormones and neurotransmitters to keep you wired. In the evening hours, they can delay your body’s normal routine and keep you up hours later than usual. Other foods like peppers, spices and even dairy can cause indigestion for some people.


Silicon Background Second only to oxygen, silicon is the most abundant element in Earth’s crust. It is found in rocks, sand, clays and soils, combined with either oxygen as silicon dioxide, or with oxygen and other elements as silicates. Silicon’s compounds are also found in water, in the atmosphere, in many plants, and even in certain animals.

Silicon is the fourteenth element of the periodic table and is a Group IVA element, along with carbon germanium, tin and lead.

History of Science. A few cultural facts about the evolution of scientific nomenclature and scientific notations. Mathematics, chemistry, etc.

Robert Boyle in the s ascribed it to “debilitation” of the air; in fact, it is oxygen being consumed. By the 18th century, it was known that in pure oxygen, phosphorus does not glow at all; [22] there is only a range of partial pressures at which it does. Heat can be applied to drive the reaction at higher pressures. The reaction is slow and only very little of the intermediates are required to produce the luminescence, hence the extended time the glow continues in a stoppered jar.

Since that time, phosphors and phosphorescence were used loosely to describe substances that shine in the dark without burning. Although the term phosphorescence is derived from phosphorus, the reaction that gives phosphorus its glow is properly called chemiluminescence glowing due to a cold chemical reaction , not phosphorescence re-emitting light that previously fell onto a substance and excited it. The half-integer nuclear spin and high abundance of 31P make phosphorus NMR spectroscopy a very useful analytical tool in studies of phosphorus-containing samples.

Two radioactive isotopes of phosphorus have half-lives suitable for biological scientific experiments. It is used in life-science laboratories in applications in which lower energy beta emissions are advantageous such as DNA sequencing. The high energy beta particles from 32 P penetrate skin and corneas and any 32 P ingested, inhaled, or absorbed is readily incorporated into bone and nucleic acids.

For these reasons, Occupational Safety and Health Administration in the United States, and similar institutions in other developed countries require personnel working with 32 P to wear lab coats, disposable gloves, and safety glasses or goggles to protect the eyes, and avoid working directly over open containers. Monitoring personal, clothing, and surface contamination is also required.

Shielding requires special consideration.


It is easy to fool yourself into believing that you are getting sufficient protein from a low-calorie diet when you measure protein by percentage of calories instead of by grams per calorie. Confusing these two measurements seems to have misled many fruitarians into believing that human protein needs are lower than they actually are. A pound person dieting on calories would need to increase their minimum required protein intake to Attempting to lose weight for long periods with a low-calorie diet that consists exclusively of fresh raw fruit and vegetables is not adequate in protein without adding concentrated sources from nuts, seeds, coconuts, avocados, etc.

Vetrano pointed out that the human body is equipped with organs to digest concentrated protein foods like nuts and seeds, so sufficient quantities of these foods belong in the natural diet of humans.

Copyright Franklyn E. The cruisers and the battleships routinely reported the number of rounds expended as part of their daily reports. Occasionally, my destroyer, the USS Edison DD made an ammo report when queried by the Squadron commander or other higher authority. But Edison did not routinely make ammo reports. We looked in the magazines after a concentrated firing period and, eye-balling the space, estimated the rounds fired since the last “inventory”.

When appropriate, we made it a point to tell the skipper that we did or did not need ammo. He was, therefore, always informed as to the essentials and included an ammunition report to higher authority when relevant. We just did not routinely report the “score” on ammo as was the established practice with fuel.

Match Background A match is a small stick of wood or strip of cardboard with a solidified mixture of flammable chemicals deposited on one end. When that end is struck on a rough surface, the friction generates enough heat to ignite the chemicals and produce a small flame. Some matches, called strike-anywhere matches, may be ignited by striking them on any rough surface.

How to Make Phosphorus By Larry Parr; Updated April 24, Phosphorous was invented by accident by alchemist Hennig Brandt In , while trying to make a philosopher’s stone (a mythical substance which could turn base metal into gold).

But after a few days immersed in the sadness of the future, I turned my attention back to the present … and, like a participant in some step program, I started to turn my attention to what I could control: This is why people and animals with chronic kidney disease are often given a protein-restricted diet. This is a double whammy because the body uses calcium to bind with the phosphorus as part of the excretion process.

You see, phosphorus occurs most abundantly in protein rich foods, but it occurs to some degree in almost all food and ingredients. But before I sing out my solution, there is something else to this story: Dogs still need other nutrients and in the end it is about balance — it means, to the best of our ability, equipping the dog Ben with what they need while omitting what is going to shorten life.

The Research and the Goal: One of the symptoms of renal failure is an acidic tummy and nausea. The result of this is reduced food drive and weight loss which was a telling symptom in Ben. Smaller and more frequent meals have played an important role for him. The goal, therefore was to choose:

The 94 Most Badass Soldiers Who Ever Lived

He decided to look for the “magic substance” that could change lead into gold in urine. In the process of heating and purifying urine, he obtained phosphorus. The discovery was important because it was the first time someone had discovered an element not known to ancient peoples. In that regard, Brand was the first person who could be called the discoverer of an element.

The incredible “”glowing”” history of the “”Devil’s element “”phosphorus Discovered by alchemists, prescribed by apothecaries, exploited by ninth-century industrialists, and abused by twentieth-century combatants, the chemical element phosphorus has fascinated us for more than three centuries.

How to Make Phosphorus By Larry Parr; Updated April 24, Phosphorous was invented by accident by alchemist Hennig Brandt In , while trying to make a philosopher’s stone a mythical substance which could turn base metal into gold. Since the time of Brandt, newer methods for producing phosphorus have been discovered, but they require much higher temperatures and more sophisticated equipment than the average individual possesses.

This article will describe how to make phosphorous the old-fashioned way.

Etymology[ edit ] Match heads Historically, the term match referred to lengths of cord later cambric impregnated with chemicals, and allowed to burn continuously. The modern equivalent of this sort of match is the simple fuse , still used in pyrotechnics to obtain a controlled time delay before ignition. But, when friction matches became commonplace, they became the main object meant by the term.

Food Combining & Portion Sizing. The old mono-meal feeding plan helps avoid wrong food combinations of concentrated protein and starch, but as has been pointed out, eating large mono meals of high-phosphorus and high-protein nuts, high-sugar fruit, or high-acid fruit can present other health challenges by overloading the system with concentrated levels of single nutrients or acid.

Chemistry in its element: End promo Chris Smith Hello – this week fertilisers, fire bombs, phossy jaw and food additives. Nina Notman Phosphorus is a non-metal that sits just below nitrogen in group 15 of the periodic table. This element exists in several forms, of which white and red are the best known. White phosphorus is definitely the more exciting of the two. As it glows in the dark, is dangerously flammable in the air above 30 degrees, and is a deadly poison.

Red phosphorus however has none of these fascinating properties. So where did it all begin?


He had the audience fully engaged throughout his presentation.

With a worldwide push to ban the use of white phosphorus matches, the Diamond Match Company got a patent for a non-poisonous match which used sesquisulfide of phophorus. U.S. President Taft requested that Diamond Match give up their patent.

Bone density scan or X-ray Bone biopsy rare. Bone disease can cause bone and joint pain, broken bones, infections and skin problems. Having problems with the amount of calcium and phosphorus in your blood can also cause heart attacks. How can I prevent bone disease? If you have kidney disease, it is important to take steps to prevent bone disease. Limit how much phosphorus you take in each day. Ask your doctor or dietitian to tell you how much phosphorus you should have.

You can also ask for a list of high-phosphorus foods and lower-phosphorus alternatives. Write down how much phosphorus you eat or drink at each meal to make sure you are not getting too much. Take a phosphate binder. This is a medicine that you take with meals to keep your body from taking in the phosphorus that comes from your foods and drinks.

Facts About Phosphorus

January 5, Hennig Brand, a German, discovered phosphorus quite by accident in while processing urine in search of a compound that would turn ordinary metals into gold. Phosphorus is now mostly isolated from the rock phosphate. There’s even a painting devoted to phosphorus’ discovery, titled “The Alchymist, in Search of the Philosopher’s Stone, Discovers Phosphorus, and prays for the successful Conclusion of his operation, as was the custom of the Ancient Chymical Astrologers.

The painter, Joseph Wright, left out some of the details, as recorded in the paper “Phosphoros Elementals” and re-described in the textbook ” Chemistry ” by Kenneth Whitten and colleagues.

Get greener gardens and lawns! Testing your soil is the smart way to grow beautiful vegetables, flowers, fruits, lawns and houseplants. Only by knowing nutrient levels in your soil can you determine what you need to add to maximize growth.

Return to Topics Files are one of man’s simplest tools, yet are capable of an unbelievable amount of cuts, forms, and shapes. Though there are only a handful of file shapes, there are numerous sizes, cuts, and wear conditions. A worn file may still be a useful file, creating a softer cut with a smoother edged line. Cutting can benefit from liquid solutions and wax lubricants, easing clogging and reducing friction and heat.

A simple file cleaner is denatured alcohol. File handles are very important. Most are too small for comfortable use. The photo is manipulated with contrast tracing, embossing, and light solarization. What if I can’t afford your prices; can you make a cheaper knife? Yes I can, but why? Sometimes a client receives a quote from me and realizes he’s chosen features, materials, finishes, and embellishments that are out of his price range. With custom knives, the inclination is to go all-out, to get the features and materials you want, often because it’s a dream knife, sometimes even a once-in-a-lifetime investment.

The client wants his money to go as far as possible, and also wants a very fine knife, one that will appreciate in value over the years.
