Slow fire

A slow fire is a term used in library and information science to describe paper embrittlement resulting from acid decay. The term is taken from the title of Terry Sanders' 1987 film Slow Fires: On the preservation of the human record. Solutions to this problem include the use of acid-free paper stocks, reformatting brittle books by microfilming, photocopying or digitization, a variety of deacidification techniques.

San Yisheng

San Yisheng was a top official of the early Western Zhou dynasty. Grand Counselor San has been renowned as the protector of both the Ji province and Ji Chang of Mount Singing Phoenix – who he has served for many upon many years. Throughout the many contributions of Commander/Grand Counselor San, he would be most remembered for subduing Chong Houhu's coalition with a simple letter of rationality during the Su Hu arc. After Ji Chang had been imprisoned for over the time of seven years, San Yisheng would continue to remain as a loyal sword of the Ji province. Once the news of Bo Yikao's death had reached the ears of the people of Mount Singing Phoenix, San would be the first to console the people and create a rational conclusion; the top priority would be to retrieve Ji Chang, not go to war against the Shang dynasty yet. Thus, San would compose a letter to Supreme Counselors Fei Zhong and You Hun and attain their consent that Ji Chang should be released for his loyalty and devotion to the king.

Felipe Flores

Felipe Ignacio Flores Chandía is a Chilean footballer who plays for Deportes Antofagasta as a striker. He has represented the Chilean national team at the Sub-17, Sub-20, professionals levels. In 2007, he was loaned to O'Higgins in Cobreloa in the second semester. Along with Fernando Meneses, Flores was released by Cobreloa prior to the playoffs in December 2007 due to breaking team rules. Coincidentally both players belong to Colo-Colo, he belongs to Colo-Colo where he did not receive many chances with the first team but in the three appearances he had in 2006 he scored one goal.

Operation Castle

Operation Castle was a United States series of high-yield nuclear tests by Joint Task Force 7 at Bikini Atoll beginning in March 1954. It followed Operation Upshot -- preceded Operation Teapot. Conducted as a joint venture between the Atomic Energy Commission and the Department of Defense, the ultimate objective of the operation was to test designs for an aircraft-deliverable thermonuclear weapon. Operation Castle was considered by government officials to be a success as it proved the feasibility of deployable "dry" fuel designs for thermonuclear weapons. There were technical difficulties with some of the tests: one device had a yield much lower than predicted, while two other bombs detonated with over twice their predicted yields. One test in particular, Castle Bravo, resulted in extensive radiological contamination; the fallout affected nearby islands including inhabitants and U. S. soldiers stationed there, as well as a nearby Japanese fishing boat, resulting in one direct fatality, continued health problems for many of those exposed.

Public reaction to the tests and an awareness of the long-range effects of nuclear fallout has been attributed as being part of the motivation for the Partial Test Ban Treaty of 1963. Bikini Atoll had hosted nuclear testing in 1946 as part of Operation Crossroads where the world's fourth and fifth atomic weapons were detonated in Bikini Lagoon. Since American nuclear weapons testing had moved to the Enewetak Atoll to take advantage of larger islands and deeper water. Both atolls were part of the American Pacific Proving Grounds; the high yields of the Castle weapons caused concern within the AEC that potential damage to the limited infrastructure established at Enewetak would delay other operations. Additionally, the cratering from the Castle weapons was expected to be comparable to that of Ivy Mike, a 10.4 megatons of TNT device tested at Enawetak in 1952 leaving a crater 1 mile in diameter marking the location of the obliterated test island Elugelab. The Ivy Mike test was the world's first "hydrogen bomb", producing a full-scale thermonuclear or fusion explosion.

The Ivy Mike device used an isotope of hydrogen, making it a "wet" bomb. The complex dewar mechanisms needed to store the liquid deuterium at cryogenic temperatures made the device three stories tall and 82 tons in total weight, far too heavy and bulky to be a usable weapon. With the success of Ivy Mike as proof of the Teller-Ulam bomb concept, research began on using a "dry" fuel to make a practical fusion weapon so that the United States could begin production and deployment of thermonuclear weapons in quantity; the final result incorporated lithium deuteride as the fusion fuel in the Teller-Ulam design, vastly reducing size and weight and simplifying the overall design. Operation Castle was charted to test four dry fuel designs, two wet bombs, one smaller device; the approval for Operation Castle was issued to JTF-7 by Major General Kenneth D. Nichols, the General Manager of the AEC, on January 21, 1954. Operation Castle was organized into seven experiments, all but one of which were to take place at Bikini Atoll.

Below is the original test schedule. The Echo test was canceled due to the liquid fuel design becoming obsolete with the success of dry-fueled Bravo as noted above. Yankee was considered obsolete and the Jughead device was replaced with a "Runt II" device, hastily completed at Los Alamos and flown to Bikini. With this revision, both of the wet fuel devices were removed from the test schedule. Operation Castle was intended to test lithium deuteride as a thermonuclear fusion fuel. A solid at room temperature, LiD, if it worked, would be far more practical than the cryogenic liquid deuterium fuel in the Ivy Mike device; the same Teller-Ulam principle would be used as in the Ivy Mike so-called "Sausage" device, but the fusion reactions were different. Ivy Mike fused deuterium with deuterium; the tritium was produced during the explosion by irradiating the lithium with fast neutrons. Bravo and Union used lithium enriched in the Li-6 isotope, while Romeo and Koon were fueled with natural lithium; the use of natural lithium would be important to the ability of the US to expand its nuclear stockpile during the Cold War nuclear arms race, since the so-called "Alloy Development Plants" were in an early stage at the time Castle was carried out.

The first plant started production in the fall of 1953. As a hedge, development of liquid deuterium weapons continued in parallel. Though they were much less practical because of the logistical problems dealing with the transport and storage of a cryogenic device, the Cold War arms race drove the demand for a viable fusion weapon; the "Ramrod" and "Jughead" devices were liquid fuel designs reduced in size and weight from their so-called "Sausage" predecessor. The "Jughead" device was weaponized, it saw limited fielding by the U. S. Air Force until the "dry" fuel H-bombs became common. Nectar was not a fusion weapon in the same sense as the rest of the Castle series. Though it used lithium fuel for fission boosting, the principal reaction material in the second stage was uranium and plutonium. Similar to the Teller-Ulam configuration, a nuclear fission explosion was used to create high temperatures and pressures to compress a second fissionable mass; this would have otherwise been too large to sustain an efficient reaction if it were triggered wit

Disculpa los malos pensamientos

"Disculpa los malos pensamientos" is a rock song by the Mexican band Panda. It was released in March 2006 as the third single from the band's third album, Para ti con desprecio; the song talks about bad thoughts that are caused by a girl's actions. The song reached the MTV TRL in Latin America, known as "Los 10+ Pedidos", where it peaked at number one, it topped Los 100+ Pedidos del 2006. The song was written by the vocalist of the band; the music video for the song debuted on March 4, 2006 on MTV Latin America in Mexico and South America. It was shot by Rodrigo Guardiola; the video starts with the vocalist of José Madero, who arrives to his girlfriend's house. She is carried by him throughout the video. Once inside the house, they have a dinner with her parents, who don't seem to notice she is dead; the parents act like zombies maybe ignoring the reality of the situation. In reality, Mariana Quintanilla is the ex-girlfriend of Ricardo Treviño; the video was shot in an old and dirty house in Monterrey, Mexico
