...Magma is melted rock at high pressure and temperature. Magma rises because it is initially less dense than the rock surrounding rock. It eventually equals the density of the surrounding rock and becomes a magma chamber. Tephra is pumice or ash that is blown into the air during eruptions. Volcanoes are generally found where tectonic plates converge and diverge; but are usually not created where tectonic plates slide past one another. As a result volcanoes can be found in all sorts of climate locations. There are four primary types of volcanoes which all have varying effects on the environment. This paper will explore these various types of volcanoes and show how they differ, as well as giving examples of eruptions for each of the types discussed. Principle Types of Volcanoes Cinder cones: Cinder cones are built from particles and blobs of congealed lava ejected from a single vent; they are the simplest forms of volcanoes. Gas charged lava is violently blown into the air and breaks up into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone. Most of these types of volcanoes have a bowl shaped crater at the summit and rarely rise more than a thousand feet or so above their surroundings. Lava flow can flow from a breach on the side of the crater or a vent from an outside flank. Lava actually rarely comes from the top because the unmolded cinders are too weak to support the pressure exerted by molten rock as it rises to the...

...Plumes: A Geological Controversy, Gillian R. Foulger explores the debate and evidence found by scientists surrounding “hotspots.” Scientists have found that many hotspot tracks originate from a large igneous province. Large igneous provinces (LIPs) are defined by the Encyclopedia of Geology as “massive crustal emplacements of predominantly iron- and magnesium-rich (mafic) rock that form by processes other than normal seafloor spreading; they are the dominant form of near-surface magmatism on the terrestrial planets and moons of our solar system” (p. 316). Hotspots that reach the earth’s surface may have three distinct origins as discussed by Courtillot et. al (2003). Between the boundary of the lower mantle and core is the deepest approximately 15-20% show features such as the presence of a linear chain of seamounts with an age progression, large igneous provinces (LIPs) at the origin of the hotspot track, the He3 to He4 ratio are consistent with deep origin. Pitcairn, Samoan and Tahitian hotspots all seem to occur at the top of large, transient, hot lava domes or superswells in the mantle. The rest seem to be of upper mantle origins and may be caused by breaking of plates when they...

...embodiment of regality, nobility, and holiness. It represents a form of art that seeks to depict the dimension of the transcendent. In other words, the Stupa Reliquary represents a type of view, in which earthly and material remains are oriented towards a transcendent and vertical plane of existence. That is to say that the piece, as a reliquary, functions as a housing of the remains of religious figures, yet because of the nature of religion itself, the relics contained within bear a sacred or transcendent element. This is an interesting piece, but it is difficult to understand without considering the background of the piece. This research will explore the context of the Stupa Reliquary to obtain a better understanding of the piece. It will focus on its function, origins, audience and how its design relates to a central Buddhist symbol. The present paper will argue that the Stupa Reliquary through its very composition, function and design attempts to capture precisely how the material world may turn itself towards...

...exactly how rifting comes about, but the process is so well displayed in East Africa (Ethiopia-Kenya-Uganda-Tanzania) that geologists have attached a name to the new plate-to-be; the Nubian Plate makes up most of Africa, while the smaller plate that is pulling away has been named the Somalian Plate (Figure 1). These two plates are moving away form each other and also away from the Arabian plate to the north. The point where these three plates meet in the Afar region of Ethiopia forms what is called a triple-junction. However, all the rifting in East Africa is not confined to the Horn of Africa; there is a lot of rifting activity further south as well, extending into Kenya and Tanzania and Great Lakes region of Africa. The purpose of this paper is to discuss the general geology of these rifts are and highlight the geologic processes involved in their formation. What is the East Africa Rift System? The oldest and best defined rift occurs in the Afar region of Ethiopia and this rift is usually referred to as the Ethiopian Rift. Further to the South a series of rifts occur which include a Western branch, the "Lake Albert Rift" or "Albertine Rift" which contains the East African Great Lakes, and an Eastern branch that roughly bisects Kenya north-to-south on a line slightly west of Nairobi...

...Experience of Biogas Technology in China Biogas has a long history in China. China is one of those countries, which pioneered in the research, development and utilization of biogas. Mr. Lo Guo-rui initiated his own research work on biogas in early 1920s with the aim to reduce import of kerosene and meet fuel crisis. He built the first biogas plant in his own house in Swatow city in Kuanglong province. The plant worked well and could meet the cooking need of his 6 family members. Subsequently he constructed about a dozen of digesters. Their performance was good. In 1929 Mr. Lo established a company named ‘Guo-Rui Gas Light Col’ for the marketing of his products. In 1930 his model received patent right from the Ministry of Industries. Soon after, he shifted to Shanghai and renamed his company as ‘China Guo Rui Gas General Cooperation’. With the construction of digesters, he started developing appliances like burner, lamp, valve etc. Gradually, he expanded his activities in 13 provinces. At his initiative more than one hundred plants have been built. In some cities biogas is used for lighting in stores. Some rich people used biogas for lighting and cooking. Even after 50 years, some of his digesters were found functioning. These are mainly rectangular. Only a few are cylindrical. The sizes vary from 6m3-108m3. These are made of cement and bricks/rocks. From technical point of view, the plants were successful. But, high construction cost hindered popularization of the technology....

...interaction of the rigid lithosphere. Geomorphological hazard – an event causing harm to people or property, caused by Geomorphological processes e.g. plate tectonic movement. Francis Bacon 1620 As far back as 1620, Francis Bacon spotted that the west coast of Africa and the east coast of South America looked as if they would fit together, like pieces of a jigsaw puzzle. Between then and 1912 other people identified further similarities between other continental coastlines. Robert Mallet 1870s Robert Mallet was a nineteenth century scientist who managed to measure the speed at which earthquakes spread. Alfred Wegner 1911 While at Marburg, in the autumn of 1911, Wegener was browsing in the university library when he came across a scientific paper that listed fossils of identical plants and animals found on opposite sides of the Atlantic. Intrigued by this information, Wegener began to look for, and find, more cases of similar organisms separated by great oceans. Orthodox science at the time explained such cases by postulating that land bridges, now sunken, had once connected far-flung continents. But Wegener noticed the close fit between the coastlines of Africa and South America. Might the similarities among organisms be due, not to land bridges, but to the continents having been joined together at one time? As he later wrote: "A conviction of the fundamental soundness of the idea took root in my mind." Such an insight, to be accepted, would require large amounts of supporting evidence...

...The Nature of Sacrifice In The History And Ideology Of The Gush Emunim There can be no argument that by living in small settlements in the hostile and explosive West Bank and Gaza Strip, Gush Emunim settlers are making some sort of sacrifice. Surrounded no doubt by hostile Palestinians who feel that the Israelis are occupying their home, religious settlers face the potential for violence and death on a daily basis. In what is becoming a more perilous state of affairs in Israel with each suicide bombing, shooting spree, or IDF incursion into the Palestinian territories and refugee camps, perhaps no one on the Israeli side faces as constant a risk of danger than the Gush Emunim. This paper will attempt to examine the very nature of sacrifice that the Gush Emunim are involved in, as well as the biblical justification for this sacrifice. I also mean to explore the biblical justification the Gush Emunim may use to support their willingness to resort to violence against the Palestinians in defending this sacrifice. Their attitude towards their hostile neighbors is the same attitude their ancestors held about the Canaanites: “you must be expelled, whether peacefully or violently, because this is our land according to God.” In the history and ideology of the Gush Emunim, examples of both Nancy Jay’s communion sacrifice as well as Hubert and Mauss’s contractual sacrifice are plenty. The sacred violence as a cultural foundation about which Gil Bailie writes can also be found. Furthermore...

...Chapter 1 THE PROBLEM AND ITS BACKGROUND Introduction This research project serves as culmination to the problem involving the restoration of the Basilica. It seeks to summarize, explain and synthesize several highlights of the topic in dialogue with the assigned texts and other readings; it will force additional research and reflections as an instrument for clarifying, defining and augmenting the author’s understanding of the major issues addressed by the proposal. The scope of the study embraces a solution that will lead the restoration of the Basilica to realities and treat the problems involving its reestablishment. Being a national heritage and considered to be one of the first Roman Catholic churches in the Philippines, it is our objective to restore a historical edifice and preserve its cultural legacy and customs. On October 15, 2013, a 7.2 magnitude earthquake shook Bohol at approximately 8:00 in the morning. It caused millions of worth of casualties, hundreds of families devastated, destroyed numerous properties and damaged many historical landmarks and churches, including the Basilica de Sto. Nino. The earthquake crushed most of the belfry and façade; walls and frescoes are cracked, leaving the church in verge of total wreckage. To prevent an entire loss, propositions involving the repair and rebuilding of the damaged areas are to be provided as well as redesigning of the structure’s stability will furnish its constancy to be able to withstand future disastrous...

...Carbon from Latin: carbo "coal" is the chemical element with symbol C and atomic number 6. As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. There are three naturally occurring isotopes, decaying with a half-life of about 5,730 years. Carbon is one of the few elements known since antiquity. There are several allotropes of carbon of which the best known are graphite, diamond, and amorphous carbon. The physical properties of carbon vary widely with the allotropic form. For example, diamond is highly transparent, while graphite is opaque and black. Diamond is among the hardest materials known, while graphite is soft enough to form a streak on paper (hence its name, from the Greek word "to write"). Diamond has a very low electrical conductivity, while graphite is a very good conductor. Under normal conditions, diamond has the highest thermal conductivity of all known materials. All carbon allotropes are solids under normal conditions with graphite being the most thermodynamically stable form. They are chemically resistant and require high temperature to react even with oxygen. The most common oxidation state of carbon in inorganic compounds is +4, while +2 is found in carbon monoxide and other transition metal carbonyl complexes. The largest sources of inorganic carbon are limestones, dolomites and carbon dioxide, but significant quantities occur in organic deposits of coal, peat, oil...

...Luis Thompson ANTH 252 Doctor Hemphill Yokuts v. Cherokee I. Introduction This paper is a basic introduction to two native North American tribes; the Yokuts of the California cultural area and the Cherokee of the Southeast cultural area. First I we will delve in to the general backgrounds of these two tribes, followed by an in depth examination of Religious beliefs practiced by each tribe, as well as the Life cycle rituals of the Yokuts and Cherokee. Directly proceeding this we will then contrast the former in depth examinations with that of the Tlingit tribe who resided in the Northwest culture area and also we will contrast The Yokuts and the Cherokee with the Zuni tribe who reside in the Southwest cultural area. General Background: Yokuts The Yokut tribe is a group of native North Americans found in the California culture area. The Yokut tribe inhabited the San Joaquin Valley of California. The Yokut tribe has been broken up into three main groups based on the area that their territory encompassed. The are the Northern Valley Yokuts who inhabited the region beginning in the northern most San Joaquin valley, present day Stockton, to the area where the San Joaquin Valley turns northward toward the Calaveras and Mokelumne rivers, or present day Modesto. The Next division is known as The Southern Valley Yokuts. This group of Yokuts lived in the Southern San Joaquin Valley from the upper forks of the Kings River, present day ...
