Gaz de houille : Rhône Alpes dispose de vraies ressources. L'idée d'Arnaud Montebourg d'extraire et d'utiliser le gaz de houille des anciennes mines de charbon, formulée lundi à Lyon, est-elle une alternative crédible au gaz de schiste ?
La ministre de l'énergie vient de tempérer l'ardeur du ministre du redressement productif en jugeant qu'il était "prématuré" d'y voir d'ores et déjà une nouvelle donne énergétique pour la France. "Un gaz en marinière" Arnaud Montebourg avait avançé cette solution lundi pour réduire la facture énergétique des industries chimiques.Il avait parlé du gaz de houille comme "d'un gaz made in France,un gaz en marinière en quelque sorte,qui pourrait assurer à la France entre 5 et 10 ans de consommation".Le ministre avait souligné par ailleurs qu'il n'était pas besoin de recourir à la fracturation hyfdraulique pour extraire le gaz de houille.Le plaidoyer d'Arnaud Montebourg avait déjà quelque peu agaçé les associations de défense de l'environnement, y voyant "une provocation".

Instead you’ll read why breaking an axis is a bad idea, and you’ll get a tutorial in Panel Charts, which are a more effective (and easier) means to show your data. The Problem People frequently ask how to show vastly different values in a single chart. Usually they ask because a few very large values (for instance, Paris in June or Madrid in May in the chart below) overwhelm the other, relatively much smaller, values. Logarithmic Scale One suggestion is to use a logarithmic scale.
Broken Axis Another suggestion is to “break” the axis, so that part of the axis shows the small values, then another part of the axis shows the large values, with a section of the axis scale removed. Another problem with this approach is that it’s cumbersome to create and nearly impossible to maintain charts like this. Panel Chart A better suggestion than either a log scale or a broken axis is to plot the data in a panel chart.

Etymology[edit] Compositions[edit] Potassium-Feldspar (K-spar) endmember KAlSi3O8[2] Albite endmember NaAlSi3O8[2] Anorthite endmember CaAl2Si2O8[2] Solid solutions between K-feldspar and albite are called alkali feldspar.[2] Solid solutions between albite and anorthite are called plagioclase,[2] or more properly plagioclase feldspar.
Alkali feldspars[edit] The alkali feldspars are as follows: Sanidine is stable at the highest temperatures, and microcline at the lowest.[7][8] Perthite is a typical texture in alkali feldspar, due to exsolution of contrasting alkali feldspar compositions during cooling of an intermediate composition. Plagioclase feldspars[edit] Standard Oil. Standard Oil Co.
Inc. was an American oil producing, transporting, refining, and marketing company. Established in 1870 as a corporation in Ohio, it was the largest oil refiner in the world.[6] Its controversial history as one of the world's first and largest multinational corporations ended in 1911, when the United States Supreme Court ruled that Standard was an illegal monopoly. John D. Rockefeller was a founder, chairman and major shareholder. With the dissolution of the Standard Oil trust into 33 smaller companies, Rockefeller became the richest man in the world. John D. Rockefeller. John Davison Rockefeller, Sr.
(July 8, 1839 – May 23, 1937) was an American business magnate and philanthropist. He was a co-founder of the Standard Oil Company, which dominated the oil industry and was the first great U.S. business trust. Rockefeller revolutionized the petroleum industry, and along with other key contemporary industrialists such as Andrew Carnegie, defined the structure of modern philanthropy. In 1870, he co-founded Standard Oil Company and actively ran it until he officially retired in 1897.[1] Rockefeller spent the last 40 years of his life in retirement at his estate, Kykuit, in Westchester County, New York.
Rockefeller was also the founder of both the University of Chicago and Rockefeller University and funded the establishment of Central Philippine University in the Philippines.
