Warning Signs That You're Zinc Deficient
 
05:53
For more info: https://draxe.com/zinc-deficiency/?utm_campaign=Youtube-Feb-2015&utm_medium=social&utm_source=youtube&utm_term=zincdeficient Today I’m going to share with you the five warning signs that you’re zinc deficient. About 75% of people in the world are deficient, so being deficient in zinc is very common. The 5 warning signs you’re zinc deficient: 1.) If you get sick a lot or have immune system issues 2.) Have leaky gut (http://draxe.com/7-signs-symptoms-you-have-leaky-gut/) 3.) If you struggle with diarrhea or IBS 4.) Thinning hair 5.) Inflammatory skin issues like acne, eczema, dermatitis, psoriasis One of the biggest factors in causing zinc deficiency is high levels of emotional stress. The second most common cause of zinc deficiency is over-exercise. The third most common reason your zinc deficient is if you’re pregnant or breast feeding. Lastly, if you’re older, you may tend to have malabsorption, which causes a zinc deficiency. In order to get more zinc in your diet, you need to consume more zinc-rich foods. The top 5 zinc-rich foods are pumpkin seeds, oysters, grass-fed beef, sprouted nuts and seeds, and peas. Additionally, probiotics are a key supplement to take when zinc deficient because it can help your overall absorption of nutrients.

Antipsychotics for schizophrenia are not very effective, Peter Gotzsche, MD
 
01:11
Hi, this is Larry Hobbs @ FatNews.com. http://fatnews.com/ https://twitter.com/fatnews Antipsychotic drugs used for schizophrenia are not very effective notes Prof. Peter Gotzsche, MD Antipsychotic drugs used for schizophrenia have very little effect on improving the disease notes Prof. Peter Gøtzsche, MD. These drugs effect on improving symptoms of the disease when measured on a scale used for schizophrenia (the PANSS) was only 6, when the difference that is considered minimally clinically relevant is 15. Dr. Gøtzsche writes: “Trials in schizophrenia [drugs] are also disappointing. “In newer submissions to the FDA, the effect on the positive and negative syndrome scale (PANSS) was only 6 even though these trials were heavily biased by cold turkey and unblinding effects. “This is far below the minimally clinically relevant effect, which is about 15.” About Dr. Gøtzsche Dr. Gøtzsche is the author of several wonderful books including Deadly Psychiatry and Organised Denial in which he talks about the problems with psychiatric drugs. He is also author of the wonderful book Deadly Medicines and Organised Crime: How Big Pharma Has Corrupted Healthcare. Dr. Gøtzsche also cofounded the Cochrane Collaboration in 1993, which is a group of scientists around the world who analyze data to try and figure out the truth about drugs and other health topics.

Ghost Metal (Chemistry Trick) - Version 2
 
03:27
In a variation of luminol chemiluminescence, we make a coin appear to glow with ghostly trails. This is an improved version of the original video in 2011 Get 100mg of luminol and dissolve it in 100 mL of 5% ammonia solution, the exact concentration isn't critical. Then add 300 mg of disodium EDTA. Add 10 mL of 3% hydrogen peroxide and dilute the whole solution into 900 mL of distilled water. Get a piece of copper metal, a penny will do, and drop it in with the lights out. The penny will start to glow as the surface dissolves to form a copper amine complex. The complex catalyzes the reaction of hydrogen peroxide on luminol and causes the solution near the coin to glow. Bright trails can be seen if the copper is moved. The EDTA will prevent the whole solution from glowing and restrict the reaction to just near the metal. This was a big problem in the original solution. A fortunate side effect is that the useful lifetime of the solution extends out to half an hour rather than just a few minutes. A fun trick to do is to bend wire words and dip them into solution.

Drug studies exaggerate benefits of psychiatric drugs, Peter Gotzsche, MD
 
02:06
Hi, this is Larry Hobbs @ FatNews.com. http://fatnews.com/ https://twitter.com/fatnews Psychiatric drug studies exaggerate benefits of these drugs by study design says Peter Gotzsche, MD “The randomised trials [of psychiatric drugs] that have been conducted do not properly evaluate the drugs’ effects,” writes Prof. Peter Gøtzsche, MD. “Almost all of them are biased because they included patients already taking another psychiatric drug. “Patients, who after a short wash-out period are randomised to placebo, go “cold turkey” and often experience withdrawal symptoms. “This design exaggerates the benefits of treatment and increases the harms in the placebo group, and it has driven patients taking placebo to suicide in trials in schizophrenia. Dr. Gøtzsche is the author of several wonderful books including Deadly Psychiatry and Organised Denial in which he talks about the problems with psychiatric drugs. He is also author of the wonderful book Deadly Medicines and Organised Crime: How Big Pharma Has Corrupted Healthcare.

Make Copper Sulfate from Copper and Sulfuric acid (3 ways)
 
04:01
We make copper sulfate from copper and sulfuric acid using two chemical methods and one electrochemical method. Copper does not directly react with sulfuric acid so some form of oxidant is needed. Hydrogen peroxide and nitric acid are excellent oxidants and the first two methods demonstrate this. The nitric acid method however produces toxic nitrogen dioxide gas so you'll need to perform this one outside or in a fumehood. Because both chemical methods are rather expensive. A very cheap electrochemical method can be performed by running a current through two copper electrodes immersed in sulfuric acid. The copper is converted to copper ions at the positive electrode and hydrogen gas is formed at the negative electrode. However if the electrodes are placed side by side then the copper ions will diffuse to the negative electrode and get converted back into copper. This is wasteful as you've used power to accomplish nothing. So the better way is to separate both by gravity with the positive electrode at the bottom. The denser solution of copper sulfate will remain near the bottom and thus increase efficiency. As a side note, the electrochemical method is actually very expensive if you use batteries as your power source. The charge on a battery generates a comparatively small quantity of total copper sulfate compared to the same cost of chemicals for the chemical methods. The cheapest way is to use a DC power supply. The cost of municipal electricity is very small compared to the cost of batteries and chemicals.

Make Sodium Silicate (AKA "Water Glass") from Cat Litter and Drain Opener (fixed)
 
07:28
(Fixed to be more informative for particular ratios) In this video we use cat litter and drain opener to make sodium silicate. This will be a valuable precursor to other silicon based chemicals in the future. Most cat litter is made from clay but "crystal" cat litter or "silica" cat litter is made from silica gel. Silica gel is amorphous silicon dioxide made by aqueous chemistry is very easy to convert into other silicon compounds. The process is quite straightforward: 60g of silica gel based cat litter is mixed with 100mL of water. Then 80g of sodium hydroxide is slowly added to dissolve the silica gel. What's produced is a solution of sodium silicate. Donate to NurdRage!

Make Sodium Silicate
 
01:50
We make sodium silicate from drain cleaner and those little gel beads you find packaged with electronic items for humidity control. The procedure is really simple, just make a solution of 10mL with 4-8grams of sodium hydroxide, use the full 8 grams if you want stoichiometric sodium silicate, and 4 grams if you want "liquid glass" solution for doing the chemical garden experiments. Heat the solution and add in 6 grams worth of crushed silica gel beads. The finer the better. if they aren't dissolving, you might need to add more water. Once it's dissolved, you'll have a concentrated solution of sodium silicate. For experiments using Sodium Silicate solution, check out these videos: http://www.youtube.com/watch?v=a45jZOc7PRY

6. Seeing Bonds by Electron Difference Density
 
51:10
Freshman Organic Chemistry (CHEM 125) Professor McBride uses a hexagonal "benzene" pattern and Franklin's X-ray pattern of DNA, to continue his discussion of X-ray crystallography by explaining how a diffraction pattern in "reciprocal space" relates to the distribution of electrons in molecules and to the repetition of molecules in a crystal lattice. He then uses electron difference density mapping to reveal bonds, and unshared electron pairs, and their shape, and to show that they are only one-twentieth as dense as would be expected for Lewis shared pairs. Anomalous difference density in the carbon-fluorine bond raises the course's second great question, "Compared to what?" 00:00 - Chapter 1.

Freshman Organic Chemistry II (CHEM 125B) Discoverers of the structure and biological activity of steroid hormones won seven Nobel Prizes between 1927 and 1975. Studying the steps involved in Woodward's 1951 "total" synthesis of cortisone provides a review of the organic reactions covered this semester. Many steps involved novel insights, others were based on lore from previous work In the area. The overall yield of such sequential syntheses is typically much lower than that of convergent syntheses. Practical syntheses of cortisone were based on modification of related steroids readily available from nature. Milestones in total synthesis include both purely intellectual work with natural products and commercially important synthesis of designed pharmaceuticals. The course ends with thanks to those, young and old, who have taught us all. 00:00 - Chapter 1. Steroids and the Medicinal Activity of Cortisone 07:43 - Chapter 2.

Make Gold from Chloroauric Acid
 
03:24
In this video we make gold by reduction of chloroauric acid with sodium metabisulfite. 4 grams of sodium metabisulfite is dissolved in 10mL of water. About 2mL of water is added to 2.6g chloroauric acid to dissolve it. Now the sodium metabisulfite is added in drop by drop. The sodium metabisulfite is reacts with the chloroauric acid to produce elemental gold, hydrochloric acid and sodium bisulfate. That brown precipitate you're seeing is actually the gold. It doesn't look like common gold because the particles of gold produced here are so small and rough that they don't reflect light in the way smooth bulk gold does. Just like how very fine sand is dull but glass is clear and shiny. The gold dust is filtered and washed with water and then melted down into gold nuggets.

I must admit I have now taken some medication
 
04:06
I have now taken a little bit of medication and feel extremely tired. The medication i am taking is Zuclopenthixol. There is also a mention of crows and rooks in this video. I was so sleepy that I did find I did have to take a whole teapoon of Nescafe coffee straight to try and counteract the tiredness. To be honest I do not know what chemicals may or may not be in that either. I once bought some coffee beans on a kind of fancy York market attempt that had been soaked or had something to do with Quantro. The coffee was not to my liking. I did used to like Cappucinos but am now fearful we are drinking them in some kind of Herculaneum. I think they were named after the monk Cappuchin anyway - or however you spell that.https://en.wikipedia.org/wiki/Capuchin. I have again now taken a cup of nettle tea. I think the nettles WANT to be used for that purpose sometimes. I learned about this possibility again from Greece on the slopes of one of the mountains there.

4th of July 2017 Fireworks Boston
 
19:04
(для текста на русском - пожайлуста, пророллируйте вниз) **** 19 min (out of 20-21 min) of fireworks in Boston on 4th of July, 2017 as seen from Cambridge side not far from Longfellow Bridge - it turned out to be a good vantage point: right distance, right angle (notice how the letters 'U' 'S' 'A' appeared perfectly correctly). Filmed with iPhone6S (alas, sometimes focus is not perfect). Music was not audible there but show was visually good enough... And, at the end, just a little bit of chemistry - which chemicals produce which color... Here it is: copper oxide or cooper chloride - BLUE color (hardest color to produce, requires perfect chemistry); strontium salts (strontium chloride), lithium salts (lithium carbonate) - RED color (for even stronger color they add some magnalium (magnesium-aluminum allow) or use strontium carbonate or strontium nitrate - BRIGHT RED); mixture of strontium (red) and copper (blue) compounds – PURPLE color; strontium oxide - ORANGE-RED color; calcium nitrate (or carbonate, or chloride) - ORANGE color; sodium chloride - YELLOW color; barium acetate (or carbonate) - GREEN color; charcoal, iron, lampback - GOLD color; burning aluminum, titanium, or magnesium - WHITE/SIVER color; adding moderately coarse magnesium produces white sparks effect. ...and so on... **** Фейерверк в Бостоне 4-го июля 2017 - как он был виден со стороны набережной в Кембридже недалеко от моста Лонгфелло - нам всё было видно под правильным углом (когда в небе вспыхивают буквы 'U' 'S' 'A', то это наглядно). Видео снято на iPhone6S (к сожалению, фокус иногда подводит, но быстро исправляется). И ещё - немного химии, поскольку всегда было интересно понять откуда берутся разные цвета фейерверка. СИНИЙ цвет - самый трудный цвет в фейерверках, поскольку синий цвет легко забивается любым другим и требует идеальной химии и идеальной чистоты реактивов. Оксид и хлорид меди производят синий цвет. При этом хлорид меди (I) CuCl даёт бирюзовый цвет. Основной карбонат меди (Cu2(CO3)(OH)2) имеет цвет от светло-голубого до ярко-голубого. Однако все они не делают цвет таким насыщенным как ацетоарсенит меди (Cu3As2O3Cu(C2H3O2)2). ЯРКО-КРАСНЫЙ цвет дают след. соли стронция: карбонат SrCO3, нитрат Sr(NО3)2 или оксалат SrС2О4 стронция. Хлорид стронция и карбонат лития Li2CO3 дают КРАСНЫЙ цвет небольшой интенсивности (для большей интенсивности цвета доб. ещё и сплав магния с алюминием). Окись стронция SrO окрашивает пламя лишь в РОЗОВЫЙ цвет (иногда дают красно-оранжевый цвет). Излучение монохлорида стронция SrCl интенсивнее и ярче излучения SrO. БРЕДНО-РОЗОВЫЙ цвет дают углекислый кальций (карбонат кальция, calcium carbonate) CaCO3, сульфат кальция CaSO4, щавелевокислый кальций (оксалат кальция, сalcium oxalate) CaC2O4. Для ФИОЛЕТОВОГО цвета смешивают соли меди (синий) и стронция (красный). Нитрат, карбонат или хлорид кальция производят ОРАНЖЕВЫЙ цвет. Хлорид натрия, нитрат натрия (натриевая селитра) NaNO3, криолит Na3AlF6 - ЖЁЛТЫЙ цвет. Ацетат или карбонат бария - ЗЕЛЁНЫЙ цвет; хлористый барий BaCl+ = ярко-зеленый цвет. Искристый ЗОЛОТОЙ - железная окалина (с углеродом), древесный уголь или сажа. Электрический БЕЛЫЙ - стружка или порошок раскаленного металла, такого как магний или аллюминий окись бария, BaO. СЕРЕБРИСТЫЙ цвет - это горение порошка (стружки) аллюминия, титана (образует искры) или магния. Добавление умеренно крупного магния производит эффект белых искр. Цинк применяется в некоторых смесях для образования дыма и эффекта звёзд. И т.д и т.д.... А вот несколько простых и безопасных (как пишут) пиротехнических опытов, которые можно провести в домашних условиях. Если сдавить корку от апельсина над пламенем свечи, то воспламенятся эфирные масла, содержащиеся в корке, и при горении образуют крошечные вспышки света. А другой опыт - не домашний, а уже дачный: поскольку бананы содержат большое количество калия, то сжигание кожуры банана в костре окрашивает пламя в фиолетовый цвет, который характерен для горения калия. Опыт «ОГНЕННЫЙ» ПОРОШОК: зажечь деревянную щепку или лучинку, потом погасить её пламя, чтобы она продолжала тлеть, и посыпать на тлеющую лучину измельченного калия марганцовокислого (перманганата калия) - везде, куда попадут крупинки перманганата, вспыхнет огонь (перманганат калия способствует горению). (Ещё одна интересная новость о пиротехнике - сейчас ведутся исследования и работы, в частности в военных лабораториях в Мериленде, в направлении сделать фейерверки экологичнее, т.е. когда вместо опасных для здоровья веществ (хлориды явл. канцерогенами) будут использоваться безвредные химич. соединения.)

Silica Gel in Water
 
06:31
Ever find those little white packets that say "throw away" and "Do Not Eat"? They are silica gel beads and they absorb like 60% of their mass in water. But, When they are dropped in water, they tend to absorb too much water. This causes them to "Crack" like ice sometimes does when you put it in a glass of water. Believe it or not but these "Gels" are used in making glass. You might have heard of the Chemical, Silicon Dioxide or SiO2. This is what these gels are.

37. Proving the Configuration of Glucose and Synthesizing Two Unnatural Products
 
54:47
Freshman Organic Chemistry II (CHEM 125B) Modern spectroscopic tools show not only the constitution, configuration, and conformation of glucose but also how it interconverts between isomeric hemiketal pyranose rings. One of mankind's great accomplishments was determinining its constitution and especially its configuration before such spectroscopy. By 1887 Heinrich Kiliani had established the constitution of glucose as an aldohexose, and with help from Emil Fischer, he developed a method for homologating aldoses. Fisher assembled a great deal of experimental evidence on interconversion of natural and artificial aldoses, and their derivatives, especially their crystalline osazones. In 1892 he used this evidence to prove logically which of eight aldohexose configurations corresponds to glucose and to provide definitive support for van't Hoff's stereochemical theory. In 1991 Cram, Tanner, and Thomas reported the NMR spectrum of antiaromatic cyclobutadiene, which they prepared by photolysis inside a clamshell molecule that they designed and constructed in order to isolate this highly reactive molecule. 00:00 - Chapter 1.

33. Green Chemistry. Acids and Acid Derivatives
 
49:20
Freshman Organic Chemistry II (CHEM 125B) Green chemistry needs new asymmetric reactions and safer, more environmental Mitsunobu reactions. The Mitsunobu mechanism is general and reliable, but atom inefficient, generating almost 30 times as much weight of by-products as of the water it is designed to eliminate. Admirably green processes include autoxidation of aldehydes to carboxylic acids using only O2, and oxidation of alcohols by loss of H2 using a ruthenium catalyst. Relative pKa values of carboxylic acids provide insight into the role of inductive and resonance effects in organic transformations. One analysis suggests that the special acidity of carboxylic acids owes four times as much to inductive as to resonance effects. Carboxylic acids can be prepared both by oxidation and by reduction. 00:00 - Chapter 1. Mitsunobu Inversion and Atom Efficiency 05:38 - Chapter 2.
