"EL COBRE ES CHILENO Y DEBE SER REFINADO EN CHILE" (Por Carlos Tomic E.) | Comité de Defensa y Recuperación del Cobre Chile exporta anualmente 1 millón de toneladas de cobre fino contenido en concentrados de cobre, equivalentes a 3 millones de toneladas de concentrados que se venden al exterior sin fundir ni refinar, y que son procesados en fundiciones y refinerías del extranjero, transformándolos en cobre electrolítico a cambio de importantes descuentos que se aplican al precio del cobre fino contenido. Pero eso no es todo. Si Chile no actúa con prontitud y decisión para corregir este cuello de botella que perjudica seriamente sus ingresos por exportaciones de cobre, dentro de los próximos 4 o 5 años se verá forzado a conceder descuentos de precio equivalentes a US$ 1.500 millones de dólares anuales, una vez que se inicie la producción de concentrados proveniente de nuevos yacimientos, más las ampliaciones de otros ya existentes. Actualmente es más rentable para el propietario de un yacimiento en Chile producir concentrados de cobre que cobre electrolítico.

The Dark Side of the Moon (Landing) | earthriderdotcom Some dispute that the U.S. sent a man to the moon. Astronaut Buzz Aldrin is the second man to walk on the moon’s surface in 1969 By Judy Berman Over eight days during July 1969, all eyes were on Apollo 11, when it became the first manned mission to land on the moon. More than 40 years after this historic event, about 6 percent of Americans still dispute that we ever set foot on the moon. It fulfilled a goal set by President John F. Apollo 11 made its landing on July 20, 1969. Yet, Bill Kaysing, considered to be the father of the moon hoax, said the whole event was staged. Kaysing, himself, was not an engineer. And, yet, his story had legs. I decided to pick an engineer’s brains on this subject: my Dad. Dad had an analytical mind and addressed some of the claims in Kaysing’s book. Here’s the scoop from the web site science.howstuffworks: Conspiracy theorists also question how the flag could flap with no wind on the moon, and that the photo had to be a hoax. I just hope it’s real soon.
Why Lead Used to Be Added To Gasoline Today I found out why lead used to be added to gasoline. “Tetraethyl lead” was used in early model cars to help reduce engine knocking, boost octane ratings, and help with wear and tear on valve seats within the motor. Due to concerns over air pollution and health risks, this type of gas was slowly phased out starting in the late 1970’s and banned altogether in all on-road vehicles in the U.S. in 1995. For a more detailed explanation of why lead used to be added to gasoline, it’s necessary to understand a little bit more about gasoline and what properties make it a good combustion material in car engines. The higher the compression in the cylinders a car’s motor can produce, the greater the power it can get out of each stroke of the piston. In 1919, Dayton Metal Products Co. merged with General Motors. Another benefit that became known over time was that Tetraethyl lead kept valve seats from becoming worn down prematurely. This hasn’t completely gotten rid of leaded gasoline.
Doctoral degrees: The disposable academic ON THE evening before All Saints' Day in 1517, Martin Luther nailed 95 theses to the door of a church in Wittenberg. In those days a thesis was simply a position one wanted to argue. Luther, an Augustinian friar, asserted that Christians could not buy their way to heaven. In most countries a PhD is a basic requirement for a career in academia. One thing many PhD students have in common is dissatisfaction. Whining PhD students are nothing new, but there seem to be genuine problems with the system that produces research doctorates (the practical “professional doctorates” in fields such as law, business and medicine have a more obvious value). Rich pickings For most of history even a first degree at a university was the privilege of a rich few, and many academic staff did not hold doctorates. Other countries are catching up. But universities have discovered that PhD students are cheap, highly motivated and disposable labour. A short course in supply and demand A very slim premium

Ancient Sumerians In Ecuador: The Father Crespi Mystery… | Hidden Inca Tours In the Amazonian Ecuadorian region called Morona Santiago there is a very deep cavern, known in Spanish as Cueva de los Tayos (Cave of the Oilbirds). According to some researchers the true discoverer of the huge archaeological treasures of the Cueva de los Tayos was not the Hungarian Juan Moricz, but rather the Salesian priest Carlo Crespi (1891-1982), a native of Milan, Italy. Carlo Crespi, who arrived to the Amazonian Ecuador area of Cuenca in 1927, was able to win the trust of the natives Jibaro, and so they did deliver to him, over decades, hundreds of fabulous archaeological pieces dating back to an unknown time, many of them made of gold or golden, often masterfully carved with archaic hieroglyphs that, to date, no one has been able to decipher. From 1960 Crespi obtained from the Vatican the permission to open a museum in the city of Cuenca, where was located his Salesian mission. In 1962 there was a fire, and some pieces were lost forever.

From the Russian revolution of 1917 to Stalinist totalitarianism - Agustín Guillamón A historical essay on the transition from Russian Revolution of the Soviets to bureaucratic dictatorship under Stalin, with special emphasis on the period extending from the February Revolution to the period of War Communism. From the Russian Revolution of 1917 to Stalinist Totalitarianism – Agustín Guillamón Introduction The Russian Revolution is the most important historical event of the 20th century, and for some historians it is even accounted as one of the great events of human history. Its influence on international relations, political ideologies and word history from 1917 to 1991 is indisputable. The Russian Revolution must not be understood as a mere coup d’état, reduced to the storming of the Winter Palace, but as a historical process that began with Bloody Sunday and the revolutionary events of 1905, and underwent an uninterrupted period of development until the mid-1920s. The Three Conceptions of the Russian Revolution before 1917 From 1905 to the First World War The April Theses
