War On Minerals
 
09:32
"What happens when they finish mining? They're going to leave and what will happen to the toxic pit? It needs to be detoxified every day. If it's not detoxified every day it will get overly toxic. And when it overflows as it will, that toxic water will go to our rivers and streams. And who suffers? Our community. That toxic pit is going to be there for eternity. So who is going to take care of that toxic pit? Tax payer's money? And who is taking the risk? Our people for eternity? And where are these mining industries? They just leave." ~ Gina Lopez (C) Ms. Regina "Gina" Lopez https://www.facebook.com/GinaLopezPH Documentary about "War on Minerals", the influence of Mining Corporations in Philippine Politics. The film "War on Minerals" will premiere in Manila in December 2017 under Springfilm Foundation, Directed by Jacco Groen.

Heart of the Spiral's Color & Stone Energy Reading (April 15-30)
 
08:19
Color and Stone Energy Reading for April 15 -30, 2012 On the 15th, the pink energy of the previous days becomes tinged with violet to create a pinkish lavender or light plum. One of the most soothing colors used in vibrational healing, this color brings feelings of security and helps us cope with transitions. The stress that often accompanies change will be easier to handle as the pink-lavender remains with us till nightfall on the 17 th. Just take a deep breath and go with the flow! Fluorite, especially purple or lavender fluorite, brings a calming and grounding influence to this time of transition. It enhances intuition and connection to our spiritual source. Meditating with fluorite will be beneficial and effective during these pink-lavender days. Fluorite remains the most harmonious stone when the color shifts to teal on the evening of the 17 th. Combining the green of the heart chakra and the blue of the throat chakra, teal encourages us to speak our truth. Dishonesty cannot withstand this color vibration, so lies and deception may be revealed during this period, which lasts through the 19th. Teal charges our immune system and restores our physical and psychological integrity. Sometimes teal's presence prepares us for an attack, so if you find yourself exposed to a contagious disease or faced with criticism for your actions, know that you have been energetically fortified by this infusion of teal. Green or blue shades of fluorite provide grounding and healing for this time, as well as lightening the heart and enhancing communication. The 20th brings an abrupt change in the prevailing energy, as red-orange now fills our environment. Opposite teal on the color wheel, red-orange is stimulating rather than soothing. If teal is "all talk," then red-orange is "all action." This color promotes physical vitality and activity; under its influence, group activities such as team sports gain appeal. Courage is enhanced, but beware of taking unnecessary risks if that courage borders on recklessness; otherwise, you may need the immune boost provided by the teal energy! Use red jasper to ground yourself and bring the vital energy of the universe completely into your body. It also purifies the blood and brings cheerfulness, friendliness, and romance to our lives. The 22nd dawns with a brief transitional period of pink—a rejuvenating and playful energy—but white predominates by mid-morning. White restores innocence and trust, clearing away obstacles, fears, and outworn thought patterns that hinder us from becoming the absolute best we can be. Like the white period we had earlier in the month, this is a time when the universe responds quickly to our thoughts and expectations, creating the world from that mental energy, so try to focus on the positive, not the negative; on the life you want, not the life you have, if the life you have is full of problems or disappointments. White selenite harmonizes with the energy now, cleaning energetic debris from our personal energy systems and our surroundings. The white energy stays with us until the afternoon of the 25th. However, white selenite's influence fades on the 24th, to be replaced by golden selenite. Golden tiger's eye also becomes a prominent stone at this time. Both of these stones help us feel self- assured and confident. By connecting our everyday selves with our higher selves, golden selenite brings spiritual guidance to our actions, while golden tiger's eye brings those actions through to productive, material results. If you feel inspired to take on a leadership role, now is the time to step forward and let your abilities shine. Late afternoon of the 25th finds us under the influence of light brown or tan energy, which lasts until the 28th. This is a good time to get "down to earth"—literally! A grounding color, light brown highlights earth energies. This is an ideal time for farming, gardening, hiking, and any activity that puts you in direct contact with the earth. Ecological issues demand attention, and vegan foods are particularly nutritious and delicious now. This is also a wonderful time for human/animal relationships, so spend some quality time with your pets, consider adopting a new animal companion, or get involved with rescue or preservation foundations. Golden-brown tiger's eye continues to supply beneficial stone energy, and so does agate, especially agate with bands of brown and tan. They link us to Mother Earth through our root chakras and enable us to draw sustenance from her boundless life force, while reminding us that we share our world in partnership with the plants and animals.

Gold Mine Adventure in Tenerife

Free video about gold mine. This free video was created for you by http://epsos.de and can be used for free under the creative commons license with the attribution of epSos.de as the original author of this gold mine video. Thank you for supporting the creative commons movement !! The Teide National Park occupies the highest part of the island of Tenerife and Spain In Teide National Park comprises 168 higher plants are added. Of these, 58 are considered endemic Canarian plants. At present, according to the National Catalogue of Endangered Species, three plant species are in danger of extinction and other twelve in vulnerable situation. For many endemic, walls and cavities that form the Glens stones, they are a true refuge for conservation. The similarity between environmental and geological conditions of the Teide National Park and the planet Mars have turned this enclave in volcanic benchmark for Mars related studies. The similarities between Mars and parts of Tenerife make the island the ideal place for testing instruments traveling to Mars and reveal past or present life on that planet. In 2010 a research team tested in Las Canadas del Teide, the Raman instrument to be sent in the next expedition to Mars. To determine the gold wealth in mineral veins or veins of a small pan about 20 cm in diameter is used, similar to a bucket in Chile and Argentina is often called scow ; the moderately fine ore is ground, a handful placed in the scow, stirred with water, and gold sits in the background. This way you can calculate the amount of gold contained in the ore. With a metal detector, a person can walk around an area of exploration and consistently below the surface. The sensor can give a positive measure a quantity of gold at a depth of one meter below the surface. As the device is easy to operate and highly mobile, this method of prospecting is very popular among gold diggers. The minerals extracted from the veins or veins that have a good concentration of gold, especially free and granulated particles are mixed with water and ground in a stones called quimbaletes, those with a concavity that allows use as a mortar. Then mercury is added to form an amalgam with gold, which is separated from the rest straining through a fine cloth. Then it refoga or burning mercury amalgam to evaporate, leaving the gold in the form of balls, whose size depends on the amount of metal in the ore. This procedure is not only harmful to the miner who practice, who hopes of mercury vapors removed during heating, but also to the surrounding areas, as the evaporated mercury condenses contaminating land and water. Approximately 45% of 2011 funded gold come from the People's Republic of China, Australia, the United States, Russia and South Africa. The deepest gold mines in the world are located in South Africa. There gold is mined almost 4000 meters below the surface. In early 2011 planned mining company AngloGold Ashanti already shafts in up to 5,000 meters deep. The main occupations of a mining include drilling rock with picks and shovels or using power tools to extract the mineral, shore up tunnels with wooden supports to prevent its collapse, deploy waterways to transport stone or mineral load the trucks for transport abroad. The work of a miner in the interior of the mine is hard. First, they are deprived of sunlight so they should illuminated by lights attached to their helmets. Second, it's a dirty job as mineral dust permeates the clothes, hair and skin of workers. The mining work requires physical effort and is not without risks. Often they must work in awkward postures or inclined to travel long distances or kneeling to reach the vein. Moreover, they are often exposed to landslides or rock falls that can cause fractures from small to death by crushing. Miners can also be brought rebanaduras and amputations when working with sharp tools. The agreement number 45 of the International Labour Organisation, adopted on June 21 of 1935, Article 2, prohibits the employment of women in underground mines. This agreement has been ratified by 70 countries, 28 of which have reported. Thank you for supporting the creative commons movement !!

Leadership in Sensitive International Missions | Voices from the Field | Bill Richardson
 
01:03:13
The Decision-making: Voices from the Field webcast leadership discussion series at Harvard School of Public Health invites leaders to speak about their experiences making decisions that affect global health. Highly interactive and candid, the series is produced in The Leadership Studio for a student audience. The high-definition webcast is streamed live and posted for future viewing. Students learn from experienced leaders about decisions that were effective, decisions that failed, and which decisions, if any, could have been made differently. Watch the entire series at http://hsph.me/voices. Bill Richardson completed his second term as Governor of New Mexico in 2010. Governor Richardson moved New Mexico forward in several important areas, including making New Mexico the "Clean Energy State" by requiring that utilities meet 20% of New Mexico's electrical demand from renewable sources and expanding access to quality health care by implementing several initiatives that provide affordable coverage solution options for every child under the age of 12 years old. In his former role as Congressman, Richardson served as a special envoy on many sensitive international missions, winning the release of hostages, American servicemen, and prisoners in North Korea, Iraq, Cuba and Sudan. Governor Richardson spoke at the Harvard School of Public Health on March 30, 2011.
Environmental impact of the energy industry
 
15:22
The environmental impact of the energy industry is diverse. Energy has been harnessed by human beings for millennia. Initially it was with the use of fire for light, heat, cooking and for safety, and its use can be traced back at least 1.9 million years. In recent years there has been a trend towards the increased commercialization of various renewable energy sources. Consumption of fossil fuel resources leads to global warming and climate change. In most parts of the world little change is being made to slow these changes. If the peak oil theory proves true, and more explorations of viable alternative energy sources are made, our impact could be less hostile to our environment. This video is targeted to blind users.

This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution. The pollutant often creates a contaminant plume within an aquifer. Movement of water and dispersion within the aquifer spreads the pollutant over a wider area. Its advancing boundary, often called a plume edge, can intersect with groundwater wells or daylight into surface water such as seeps and springs, making the water supplies unsafe for humans and wildlife. The movement of the plume, called a plume front, may be analyzed through a hydrological transport model or groundwater model. Analysis of groundwater pollution may focus on soil characteristics and site geology, hydrogeology, hydrology, and the nature of the contaminants. Pollution can occur from on-site sanitation systems, landfills, effluent from wastewater treatment plants, leaking sewers, petrol filling stations or from over application of fertilizers in agriculture. Pollution (or contamination) can also occur from naturally occurring contaminants, such as arsenic or fluoride. Using polluted groundwater causes hazards to public health through poisoning or the spread of disease. Different mechanisms have influence on the transport of pollutants, e.g. diffusion, adsorption, precipitation, decay, in the groundwater. The interaction of groundwater contamination with surface waters is analyzed by use of hydrology transport models.

Walt has created stickers he believes will work against 5G. What seems to missing by my critics is that the 5G technology needs to be stopped period. By agreeing to this technology you are making a contract allowing a technological system to be built affording the operators the ability to target specific populations with absolutely capabilities of mind control or death. There is no reason for this system if the goal is only enhanced communications. It is NOT NEEDED. And I for one absolutely reject the concept that corporations can ramrod their technologies on entire communities and states so they can make a f’ing profit...or more likely have the ability to make us all into zombies. While Shungite makes an EM/WiFi signal safe from the destructive nature of the waves themselves, we still cannot control what those signals are doing. This 5G technology has been tested and PROVED to disrupt cells in their rate of growth, in their functions and in their overall shape. By allowing the system you are accepting ultimate control. And yes it will take a social revolution to stop it. Think it is about time.... Some articles you may want to read: - Dr. Devra Lee Davis of the Environmental Health Trust – explains: Israeli research studies presented at an international conference reveal that the same electromagnetic frequencies used for crowd control weapons form the foundation of the latest network – branded as 5G – that will tie together more than 50 billion devices as part of the Internet of Things. Current investigations of wireless frequencies in the millimeter and submillimeter range confirm that these waves interact directly with human skin, specifically the sweat glands. Dr. Ben-Ishai of the Department of Physics, Hebrew University, Israel recently detailed how human sweat ducts act like an array of helical antennas when exposed to these wavelengths. Scientists cautioned that before rolling out 5G technologies that use these frequencies, research on human health effects needed to be done first to ensure the public and environment are protected. http://www.globalresearch.ca/the-same-frequencies-used-for-pain-inflicting-crowd-control-weapons-form-the-foundation-of-the-network-that-will-tie-together-more-than-50-billion-devices-as-part-of-the-internet-of-things/5580280 - Millimeter waves are broadcast at frequencies...that require minimal power to operate and can be placed every 250 meters or so throughout cities. To prevent signals from being dropped, carriers could install thousands of these stations in a city to form a dense network that acts like a relay team, receiving signals from other base stations and sending data to users at any location. http://spectrum.ieee.org/video/telecom/wireless/everything-you-need-to-know-about-5g - A recent New York study which experimented with 60GHz waves stated that “the analyses of penetration depth show that more than 90% of the transmitted power is absorbed in the epidermis and dermis layer.” Effects on the Eyes Effects On The Heart Immune System Effects Effects on Cell Growth Rates Effects on Bacteria Resistance Effects on Plant Health Effects on the Atmosphere and Depletion of Fossil Fuels Disruption of the Natural Ecosystem Most 5G Studies Mis-Leading https://www.citizens.org/5949-2/

Fluoride salts typically have distinctive bitter tastes, and are odorless. Its salts and minerals are important chemical reagents and industrial chemicals, mainly used in the production of hydrogen fluoride for fluorocarbons. Fluoride is classified as a weak base since it only partially associates in solution, but concentrated fluoride is corrosive and can attack the skin. Fluoride is the simplest fluorine anion. In terms of charge and size, the fluoride ion resembles the hydroxide ion. Fluoride ions occur on earth in several minerals, particularly fluorite, but are present only in trace quantities in bodies of water in nature.

It is a relatively rare element in the universe, usually occurring as a product of the spallation of larger atomic nuclei that have collided with cosmic rays. Within the cores of stars beryllium is depleted as it is fused and creates larger elements. It is a divalent element which occurs naturally only in combination with other elements in minerals. Notable gemstones which contain beryllium include beryl (aquamarine, emerald) and chrysoberyl. As a free element it is a steel-gray, strong, lightweight and brittle alkaline earth metal. Beryllium improves many physical properties when added as an alloying element to aluminium, copper (notably the alloy beryllium copper), iron and nickel. Beryllium does not form oxides until it reaches very high temperatures. Tools made of beryllium copper alloys are strong and hard and do not create sparks when they strike a steel surface. In structural applications, the combination of high flexural rigidity, thermal stability, thermal conductivity and low density (1.85 times that of water) make beryllium metal a desirable aerospace material for aircraft components, missiles, spacecraft, and satellites. Because of its low density and atomic mass, beryllium is relatively transparent to X-rays and other forms of ionizing radiation; therefore, it is the most common window material for X-ray equipment and components of particle detectors. The high thermal conductivities of beryllium and beryllium oxide have led to their use in thermal management applications. The commercial use of beryllium requires the use of appropriate dust control equipment and industrial controls at all times because of the toxicity of inhaled beryllium-containing dusts that can cause a chronic life-threatening allergic disease in some people called berylliosis.

Thorium is silvery and tarnishes black when it is exposed to air, forming thorium dioxide; it is moderately hard, malleable, and has a high melting point. Thorium is an electropositive actinide whose chemistry is dominated by the +4 oxidation state; it is quite reactive and can ignite in air when finely divided. All known thorium isotopes are unstable. The most stable isotope, 232Th, has a half-life of 14.05 billion years, or about the age of the universe; it decays very slowly via alpha decay, starting a decay chain named the thorium series that ends at stable 208Pb. In the universe, thorium and uranium are the only two radioactive elements that still occur naturally in large quantities as primordial elements. It is estimated to be over three times more abundant than uranium in the Earth's crust, and is chiefly refined from monazite sands as a by-product of extracting rare-earth metals. Thorium was discovered in 1829 by the Norwegian amateur mineralogist Morten Thrane Esmark and identified by the Swedish chemist Jöns Jacob Berzelius, who named it after Thor, the Norse god of thunder. Its first applications were developed in the late 19th century. Thorium's radioactivity was widely acknowledged during the first decades of the 20th century. In the second half of the century, thorium was replaced in many uses due to concerns about its radioactivity. Thorium is still being used as an alloying element in TIG welding electrodes but is slowly being replaced in the field with different compositions. It was also a material in high-end optics and scientific instrumentation, and as the light source in gas mantles, but these uses have become marginal. It has been suggested as a replacement for uranium as nuclear fuel in nuclear reactors, and several thorium reactors have been built.

Global Antimony Market 2015-2019 by Market Research Store
 
00:31
Antimony is used for the production of flame retardants. It is found in its ore form and usually appears as a lustrous tin-white metal. Antimony is primarily mined in China and the country holds the majority of its reserves. In 2009, the government of China has classified antimony as a strategic metal and a rare element of the earth, resulting in supply constraints worldwide. Apart from flame retardants, the other major applications of antimony are in lead batteries, as an alloy strengthening agent, a catalyst, and in ceramics. In 2014, owing to supply constraints worldwide, the EU and the British Geological Survey listed Antimony at the top of the list for metals and minerals. Global Antimony Market to grow at a CAGR of 5.03 percent over the period 2014-2019.

It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes each conclude a major decay chain of heavier elements. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the group, lead tends to bond with itself; it can form chains, rings, and polyhedral structures. Lead is easily extracted from its ores; prehistoric people in Western Asia knew of it. Galena, a principal ore of lead, often bears silver, interest in which helped initiate widespread extraction and use of lead in ancient Rome. Lead production declined after the fall of Rome and did not reach comparable levels until the Industrial Revolution. In 2014, the annual global production of lead was about ten million tonnes, over half of which was from recycling. Lead's high density, low melting point, ductility and relative inertness to oxidation make it useful. These properties, combined with its relative abundance and low cost, resulted in its extensive use in construction, plumbing, batteries, bullets and shot, weights, solders, pewters, fusible alloys, white paints, leaded gasoline, and radiation shielding. In the late 19th century, lead's toxicity was recognized, and its use has since been phased out of many applications. Lead is a toxin that accumulates in soft tissues and bones, it acts as a neurotoxin damaging the nervous system and interfering with the function of biological enzymes. It is particularly problematic in children: even if blood levels are promptly normalized with treatment, neurological disorders, such as brain damage and behavioral problems, may result.

It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes each conclude a major decay chain of heavier elements. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the group, lead tends to bond with itself; it can form chains, rings, and polyhedral structures. Lead is easily extracted from its ores; prehistoric people in Western Asia knew of it. Galena, a principal ore of lead, often bears silver, interest in which helped initiate widespread extraction and use of lead in ancient Rome. Lead production declined after the fall of Rome and did not reach comparable levels until the Industrial Revolution. In 2014, the annual global production of lead was about ten million tonnes, over half of which was from recycling. Lead's high density, low melting point, ductility and relative inertness to oxidation make it useful. These properties, combined with its relative abundance and low cost, resulted in its extensive use in construction, plumbing, batteries, bullets and shot, weights, solders, pewters, fusible alloys, white paints, leaded gasoline, and radiation shielding. In the late 19th century, lead's toxicity was recognized, and its use has since been phased out of many applications. Lead is a toxin that accumulates in soft tissues and bones, it acts as a neurotoxin damaging the nervous system and interfering with the function of biological enzymes. It is particularly problematic in children: even if blood levels are promptly normalized with treatment, neurological disorders, such as brain damage and behavioral problems, may result.
