Was it a great continent surrounded by huge ocean as Alfred Wegener (1912) claimed? Earth is the most amazing planet in our Milky Way galaxy and may be in the universe. It is the only deformed planet that has a variable orbit around the sun and the only planet that has water on its surface. How did earth deformation take place? What does cause earth to deform? What are the results of earth deformation? How does its orbit around the sun change? First earth size computation can be achieved only considering the quantum of iron and nickel rested into earth core. This paper introduces a new theory “Earth expansion Theory”. The principles of “Earth Expansion Theory” are leading to new approaches and concepts to interpret whole earth dynamics and its geological and environmental changes. This theory is not an attempt to unify the two divergent dominant theories of continental drift, plate tectonic theory and earth expansion theory. The new theory is unique since it has a mathematical derivation, explains all the change to and around earth in terms of geological and environmental changes, and answers all unanswered questions in other theories. This paper presents the basic of the introduced theory and discusses the mechanism of earth expansion and how it took place, the forces that made the expansion. The mechanisms of earth size change from its spherical shape with radius about 3447.6 km to an elliptic shape of major radius about 6378.1 km and minor radius of about 6356.8 km and how it took place, are introduced and discussed. This article also introduces, in a more realistic explanation the formation of oceans and seas, the preparation of river formation. It also addresses the role of iron in earth size enlargement process within the continuum mechanics framework. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earth%20size" title="earth size">earth size</a>, <a href="https://publications.waset.org/abstracts/search?q=earth%20expansion" title=" earth expansion"> earth expansion</a>, <a href="https://publications.waset.org/abstracts/search?q=continuum%20mechanics" title=" continuum mechanics"> continuum mechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=continental%20and%20ocean%20formation" title=" continental and ocean formation"> continental and ocean formation</a> </p> <a href="https://publications.waset.org/abstracts/26111/first-earth-size" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26111.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">448</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1362</span> Bosporus Evolution: Its Role in the Black Sea Forming</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20V.%20Kuzminov">I.

Up till nowadays, there is no distinct picture of the historical and geographical events of the last 10 thousand years on the territory from Altai up to the Alps. The present article is an attempt to clarify and, moreover, link the presented version to the historical and climatic events of this period. The paper is a development of the basic idea stated in "Hypothesis on the Black Sea origin". The succession of events in dynamics is offered in this article. In the article, it is shown that fluctuation of the level of the World Ocean is a mirror of the basic events connected with the climate on the Earth on the one hand and hydraulic processes on the other hand. In the present article, it is come out with the assumption that at the formation of passage, there were some cycles of change in a level of the World ocean. The phase of the beginning of climate warming is characterized by an increase in the level of inland water bodies on the way of meltwater runoff and an increase in the World ocean level. The end of the warming phase is characterized by the continuation of a rise in the level of the World ocean and the drying up of inland water bodies deprived of meltwater replenishment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bosporus" title="Bosporus">Bosporus</a>, <a href="https://publications.waset.org/abstracts/search?q=Ryan-Pitman%20hypothesis" title=" Ryan-Pitman hypothesis"> Ryan-Pitman hypothesis</a>, <a href="https://publications.waset.org/abstracts/search?q=fluctuations%20of%20the%20World%20Ocean%20level" title=" fluctuations of the World Ocean level"> fluctuations of the World Ocean level</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20Paratethys%20Sea" title=" the Paratethys Sea"> the Paratethys Sea</a>, <a href="https://publications.waset.org/abstracts/search?q=catastrophic%20breakthrough" title=" catastrophic breakthrough"> catastrophic breakthrough</a> </p> <a href="https://publications.waset.org/abstracts/152551/bosporus-evolution-its-role-in-the-black-sea-forming" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152551.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">110</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1361</span> Wave Energy: Efficient Conversion of the Big Waves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md.%20Moniruzzaman">Md.

This study analysed the buying decisions of the freight forwarders and validated the process of stages that the freight forwarders’ pass through before choosing an ocean container carrier. Factor analysis was applied to data collected from 105 freight forwarding companies to unveil the influential factors the freight forwarders’ consider important when selecting an ocean container carrier. This study did not only analysed the buying behaviour of the freight forwarders but also unveiled the influential factors affecting the competitiveness of the ocean container carriers in their market share maximisation. Furthermore, the study have made a methodological contribution that helps in better understanding of the critical factors influencing the selection of the ocean container carriers from the freight forwarders’ perspective. The implications of the freight forwarders’ buying behaviour is important to the ocean container carriers because it have severe effect on the market share of the ocean container carriers and the percentage of customers they control within the liner shipping sector. The findings of this study will help the ocean container carriers to formulate relevant marketing strategies in attracting the freight forwarders in purchasing the liner shipping service. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ocean%20carrier" title="ocean carrier">ocean carrier</a>, <a href="https://publications.waset.org/abstracts/search?q=freight%20forwarder" title=" freight forwarder"> freight forwarder</a>, <a href="https://publications.waset.org/abstracts/search?q=buying%20behaviour" title=" buying behaviour"> buying behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=influential%20factors" title=" influential factors"> influential factors</a> </p> <a href="https://publications.waset.org/abstracts/53684/an-empirical-analysis-of-the-freight-forwarders-buying-behaviour-implications-for-the-ocean-container-carriers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53684.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">251</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1359</span> Developing Heat-Power Efficiency Criteria for Characterization of Technosphere Structural Elements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victoria%20Y.%20Garnova">Victoria Y.

That is why the investigation of the Earth's rotation is very important, and it has a long history of study. The invention of quartz clocks in the 1930s, atomic time in the 1950s, and the introduction of modern technology into astronomic observation in recent years resulted in rapid development of the study of Earth’s rotation. The theory of the Earth's rotation, however, has not been up to the high level of astronomic observation due to the limitation of time. As a typical example, we can take the problems that cover the instabilities of the Earth’s rotation, proved completely by the astronomic observations as well as polar motion, the precession and nutation of the Earth's rotation axis, which have not been described in a single equation in a quantificational way from the unique law of Earth rotation. In particular, at present the problem of what is the main factor causing the instabilities of the Earth rotation has not been solved clearly in quantificational ways yet. Therefore, this paper gives quantificational proof that the main factor that causes the instabilities of the Earth's rotation is the moment of external force other than variations in the relative atmospheric angular momentum due to the time limitation and under some assumptions or the moment of inertia of the Earth’s body. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atmospheric%20angular%20momentum" title="atmospheric angular momentum">atmospheric angular momentum</a>, <a href="https://publications.waset.org/abstracts/search?q=instabilities%20of%20the%20earth%E2%80%99s%20rotation" title=" instabilities of the earth’s rotation"> instabilities of the earth’s rotation</a>, <a href="https://publications.waset.org/abstracts/search?q=law%20of%20the%20earth%E2%80%99s%20rotation%20change" title=" law of the earth’s rotation change"> law of the earth’s rotation change</a>, <a href="https://publications.waset.org/abstracts/search?q=moment%20of%20inertia%20of%20the%20earth" title=" moment of inertia of the earth"> moment of inertia of the earth</a> </p> <a href="https://publications.waset.org/abstracts/182768/main-factor-that-causes-the-instabilities-of-the-earths-rotation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182768.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">79</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1356</span> Advertising Campaigns for a Sustainable Future: The Fight against Plastic Pollution in the Ocean</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mokhlisur%20Rahman">Mokhlisur Rahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ocean inhibits one of the most complex ecosystems on the planet that regulates the earth's climate and weather by providing us with compatible weather to live. Ocean provides food by extending various ways of lifestyles that are dependent on it, transportation by accommodating the world's biggest carriers, recreation by offering its beauty in many moods, and home to countless species. At the essence of receiving various forms of entertainment, consumers choose to be close to the ocean while performing many fun activities. Which, at some point, upsets the stomach of the ocean by threatening marine life and the environment. Consumers throw the waste into the ocean after using it. Most of them are plastics that float over the ocean and turn into thousands of micro pieces that are hard to observe with the naked eye but easily eaten by the sea species. Eventually, that conflicts with the natural consumption process of any living species, making them sick. This information is not known by most consumers who go to the sea or seashores occasionally to spend time, nor is it widely discussed, which creates an information gap among consumers. However, advertising is a powerful tool to educate people about ocean pollution. This abstract analyzes three major ocean-saving advertisement campaigns that use innovative and advanced technology to get maximum exposure. The study collects data from the selected campaigns' websites and retrieves all available content related to messages, videos, and images. First, the SeaLegacy campaign uses stunning images to create awareness among the people; they use social media content, videos, and other educational content. They create content and strategies to build an emotional connection among the consumers that encourage them to move on an action. All the messages in their campaign empower consumers by using powerful words. Second, Ocean Conservancy Campaign uses social media marketing, events, and educational content to protect the ocean from various pollutants, including plastics, climate change, and overfishing. They use powerful images and videos of marine life. Their mission is to create evidence-based solutions toward a healthy ocean. Their message includes the message regarding the local communities along with the sea species. Third, ocean clean-up is a campaign that applies strategies using innovative technologies to remove plastic waste from the ocean. They use social media, digital, and email marketing to reach people and raise awareness. They also use images and videos to evoke an emotional response to take action. These tree advertisements use realistic images, powerful words, and the presence of living species in the imagery presentation, which are eye-catching and can grow emotional connection among the consumers.

That is why the investigation of the Earth's rotation is very important, and it has a long history of study. The invention of quartz clocks in the 1930s and atomic time 1950s and the introduction of modern technology into astronomic observation in recent years resulted in rapid development of the study of Earth’s rotation. The theory of the Earth rotation, however, has not been up to the high level of astronomic observation due to limitation of the time such as impossibility of quantitative calculation of moment of external force for Euler’s dynamical equation based on Newtonian mechanics. As a typical example, we can take the problems that cover the instabilities of the Earth’s rotation proved completely by the astronomic observations as well as polar motion, the precession and nutation of the Earth rotation axis which have not been described in a single equation in a quantitative way from the unique law of Earth rotation. In particular, at present the problem of what the main factor causing the instabilities of the Earth rotation is has not been solved clearly in quantitative ways yet. Therefore, this paper addresses quantitative proof that the main factor which causes the instabilities of the Earth rotation is the moment of external force rather than variations in the relative atmospheric angular momentum and in moment of inertia of the Earth’s body due to the time limitation and under some assumptions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atmospheric%20angular%20momentum" title="atmospheric angular momentum">atmospheric angular momentum</a>, <a href="https://publications.waset.org/abstracts/search?q=instabilities%20of%20the%20Earth%E2%80%99s%20rotation" title=" instabilities of the Earth’s rotation"> instabilities of the Earth’s rotation</a>, <a href="https://publications.waset.org/abstracts/search?q=law%20of%20the%20Earth%E2%80%99s%20rotation%20change" title=" law of the Earth’s rotation change"> law of the Earth’s rotation change</a>, <a href="https://publications.waset.org/abstracts/search?q=moment%20of%20%20%20%20inertia%20of%20the%20Earth" title=" moment of inertia of the Earth"> moment of inertia of the Earth</a> </p> <a href="https://publications.waset.org/abstracts/192592/on-the-main-factor-that-causes-the-instabilities-of-the-earth-rotation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192592.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">19</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1354</span> A Key Parameter in Ocean Thermal Energy Conversion Plant Design and Operation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yongjian%20Gu">Yongjian Gu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ocean thermal energy is one of the ocean energy sources. It is a renewable, sustainable, and green energy source. Ocean thermal energy conversion (OTEC) applies the ocean temperature gradient between the warmer surface seawater and the cooler deep seawater to run a heat engine and produce a useful power output. Unfortunately, the ocean temperature gradient is not big. Even in the tropical and equatorial regions, the surface water temperature can only reach up to 28oC and the deep water temperature can be as low as 4oC. The thermal efficiency of the OTEC plants, therefore, is low. In order to improve the plant thermal efficiency by using the limited ocean temperature gradient, some OTEC plants use the method of adding more equipment for better heat recovery, such as heat exchangers, pumps, etc. Obviously, the method will increase the plant's complexity and cost. The more important impact of the method is the additional equipment needs to consume power too, which may have an adverse effect on the plant net power output, in turn, the plant thermal efficiency. In the paper, the author first describes varied OTEC plants and the practice of using the method of adding more equipment for improving the plant's thermal efficiency. Then the author proposes a parameter, plant back works ratio ϕ, for measuring if the added equipment is appropriate for the plant thermal efficiency improvement. Finally, in the paper, the author presents examples to illustrate the application of the back work ratio ϕ as a key parameter in the OTEC plant design and operation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ocean%20thermal%20energy" title="ocean thermal energy">ocean thermal energy</a>, <a href="https://publications.waset.org/abstracts/search?q=ocean%20thermal%20energy%20conversion%20%28OTEC%29" title=" ocean thermal energy conversion (OTEC)"> ocean thermal energy conversion (OTEC)</a>, <a href="https://publications.waset.org/abstracts/search?q=OTEC%20plant" title=" OTEC plant"> OTEC plant</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20back%20work%20ratio%20%CF%95" title=" plant back work ratio ϕ"> plant back work ratio ϕ</a> </p> <a href="https://publications.waset.org/abstracts/141985/a-key-parameter-in-ocean-thermal-energy-conversion-plant-design-and-operation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141985.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">196</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1353</span> Periodic Change in the Earth’s Rotation Velocity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sung%20Duk%20Kim">Sung Duk Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kwan%20U.%20Kim"> Kwan U.

According to the previous investigation, atmospheric circulation is supposed to be a factor affecting the seasonal variations in the Earth’s rotation velocity in many cases, but the problem has not been solved yet. In order to solve the problem, it is necessary to apply dynamics to consider the Earth’s spatial motion, rotation, and change of shape of the Earth (movement of materials in and out of the Earth and change of the Earth’s figure) at the same time and in interrelation to the accuracy of post-Newtonian approximation regarding the Earth body as a system of mass points because the stability of the Earth’s rotation angular velocity is in the range of 10⁻⁸~10⁻⁹. For it, the equation was derived, which can consider the 3 kinds of motion above mentioned at the same time by taking the effect of the resultant external force on the Earth’s rotation into account in a relativistic way to the accuracy of post-Newtonian approximation. Therefore, the equation has been solved to obtain the theoretical values of periodic change in the Earth’s rotation velocity, and they have been compared with the astronomical observation data so to reveal the cause for the periodic change in the Earth’s rotation velocity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Earth%20rotation" title="Earth rotation">Earth rotation</a>, <a href="https://publications.waset.org/abstracts/search?q=moment%20function" title=" moment function"> moment function</a>, <a href="https://publications.waset.org/abstracts/search?q=periodic%20change" title=" periodic change"> periodic change</a>, <a href="https://publications.waset.org/abstracts/search?q=seasonal%20variation" title=" seasonal variation"> seasonal variation</a>, <a href="https://publications.waset.org/abstracts/search?q=relativistic%20change" title=" relativistic change"> relativistic change</a> </p> <a href="https://publications.waset.org/abstracts/182897/periodic-change-in-the-earths-rotation-velocity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182897.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">73</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1352</span> Interlinkages and Impacts of the Indian Ocean on the Nile River</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zeleke%20Ayalew%20Alemu">Zeleke Ayalew Alemu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indian Ocean and the Nile River play significant roles in shaping the hydrological and ecological systems of the regions they traverse. This study explores the interlinkages and impacts of the Indian Ocean on the Nile River, highlighting key factors such as water flow, nutrient distribution, climate patterns, and biodiversity. The Indian Ocean serves as a major source of moisture for the Nile River, contributing to its annual flood cycle and sustaining the river's ecosystem. The Indian Ocean's monsoon winds influence the amount of rainfall received in East Africa, which directly impacts the Nile's water levels. These monsoonal patterns create a vital connection between the Indian Ocean and the Nile, affecting agricultural productivity, freshwater availability, and overall river health. The Indian Ocean also influences the nutrient levels in the Nile River. Coastal upwelling driven by oceanic currents brings nutrient-rich waters from the depths of the ocean to the surface. These nutrients are transported by ocean currents towards the Red Sea and subsequently enter the Nile. This influx of nutrients supports the growth of plankton, which forms the basis of the river's food web and sustains various aquatic species. Additionally, the Indian Ocean's climate patterns, such as El Niño and Indian Ocean Dipole events, exert influence on the Nile River basin. El Niño, for example, can result in drought conditions, reduced precipitation, and altered river flows, impacting agricultural activities and water resource management along the Nile. The Indian Ocean Dipole events can influence the rainfall distribution in East Africa, further impacting the Nile's water levels and ecosystem dynamics. The Indian Ocean's biodiversity is interconnected with the Nile River's ecological system. Many species that inhabit the Indian Ocean, such as migratory birds and marine mammals, migrate along the Nile River basin, utilizing its resources for feeding and breeding purposes. The health of the Indian Ocean's ecosystem thus indirectly affects the biodiversity and ecological balance of the Nile River. Indian Ocean plays a crucial role in shaping the dynamics of the Nile River. Its influence on water flow, nutrient distribution, climate patterns, and biodiversity highlights the complex interdependencies between these two important water bodies. Understanding the interconnectedness and impacts of the Indian Ocean on the Nile is essential for effective water resource management and conservation efforts in the region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water" title="water">water</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=planning" title=" planning"> planning</a> </p> <a href="https://publications.waset.org/abstracts/172825/interlinkages-and-impacts-of-the-indian-ocean-on-the-nile-river" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172825.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">98</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1351</span> Crater Pattern on the Moon and Origin of the Moon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xuguang%20Leng">Xuguang Leng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The crater pattern on the Moon indicates the Moon was captured by Earth in the more recent years, disproves the theory that the Moon was born as a satellite to the Earth. The Moon was tidal locked since it became the satellite of the Earth. Moon’s near side is shielded by Earth from asteroid/comet collisions, with the center of the near side most protected. Yet the crater pattern on the Moon is fairly random, with no distinguishable empty spot/strip, no distinguishable difference near side vs. far side. Were the Moon born as Earth’s satellite, there would be a clear crater free spot, or strip should the tial lock shifts over time, on the near side; and far more craters on the far side. The nonexistence of even a vague crater free spot on the near side of the Moon indicates the capture was a more recent event. Given Earth’s much larger mass and sphere size over the Moon, Earth should have collided with asteroids and comets in much higher frequency, resulting in significant mass gain over the lifespan. Earth’s larger mass and magnetic field are better at retaining water and gas from solar wind’s stripping effect, thus accelerating the mass gain. A dwarf planet Moon can be pulled closer and closer to the Earth over time as Earth’s gravity grows stronger, eventually being captured as a satellite. Given enough time, it is possible Earth’s mass would be large enough to cause the Moon to collide with Earth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=moon" title="moon">moon</a>, <a href="https://publications.waset.org/abstracts/search?q=origin" title=" origin"> origin</a>, <a href="https://publications.waset.org/abstracts/search?q=crater" title=" crater"> crater</a>, <a href="https://publications.waset.org/abstracts/search?q=pattern" title=" pattern"> pattern</a> </p> <a href="https://publications.waset.org/abstracts/149225/crater-pattern-on-the-moon-and-origin-of-the-moon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149225.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">97</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1350</span> The Challenge of the Decarbonization of Shipping and Complex Imo Regulations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saiyeed%20Jakaria%20Baksh%20Imran">Saiyeed Jakaria Baksh Imran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The earth is being endangered by many of the climate related issues today. The most serious issue for the world today is the global warming. Increase in Greenhouse gas (GHG) emissions post-industrial revolution period is the prime reason for global warming. Shipping is the fifth largest GHG emitting sector worldwide. The key reason for this is because, over 90% of the world trade is conducted through ocean as the ocean alone covers 70% of the earth surface. While the countries continue to develop, trade and commerce continue to increase between them simultaneously. However, there is no sign of reduction in GHG emission from shipping because of many concerned issues. Firstly, there is technological barrier for which ships cannot just become environment friendly immediately. Secondly, there is no alternative fuel available as well. Thirdly, there is no proper mechanism to measure how much ships emit as emission from ships vary according to the size, engine type and loading capacity of ships. The International Maritime Organization (IMO) being the governing body of the international shipping has implemented MARPOL Annex VI. However, the policy alone is not enough unless there is a proper data available regarding ship emissions, which the IMO is yet to figure out. This paper will present a critical analysis of existing IMO policies such as the Energy Efficiency Design Index (EEDI), Ship Energy Efficiency Management Plan (SEEMP), Data Collection System (SEEMP) and the IMO’s Initial Strategy on Reduction of Greenhouse Gas emissions from shipping. Also, the challenges exist in implementing such policies have been presented in the paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GHG" title="GHG">GHG</a>, <a href="https://publications.waset.org/abstracts/search?q=IMO" title=" IMO"> IMO</a>, <a href="https://publications.waset.org/abstracts/search?q=EEDI" title=" EEDI"> EEDI</a>, <a href="https://publications.waset.org/abstracts/search?q=SEEMP" title=" SEEMP"> SEEMP</a>, <a href="https://publications.waset.org/abstracts/search?q=DCS" title=" DCS"> DCS</a>, <a href="https://publications.waset.org/abstracts/search?q=greenhouse%20gas" title=" greenhouse gas"> greenhouse gas</a>, <a href="https://publications.waset.org/abstracts/search?q=decarbonization" title=" decarbonization"> decarbonization</a>, <a href="https://publications.waset.org/abstracts/search?q=shipping" title=" shipping"> shipping</a> </p> <a href="https://publications.waset.org/abstracts/159986/the-challenge-of-the-decarbonization-of-shipping-and-complex-imo-regulations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159986.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1349</span> Hygrothermal Properties of Raw Earth Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ichrak%20Hamrouni">Ichrak Hamrouni</a>, <a href="https://publications.waset.org/abstracts/search?q=Tariq%20Ouahbi"> Tariq Ouahbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalija%20Lhuissier"> Natalija Lhuissier</a>, <a href="https://publications.waset.org/abstracts/search?q=Sa%C3%AFd%20Taibi"> Saïd Taibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehrez%20Jemai"> Mehrez Jemai</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Crumeyrolle"> Olivier Crumeyrolle</a>, <a href="https://publications.waset.org/abstracts/search?q=Hatem%20Zenzri"> Hatem Zenzri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Raw earth is the oldest building technique used for over 11 centuries, thanks to its various benefits. The most known raw earth construction technics are compressed earth blocks, rammed earth, raw earth concrete, and daub. The raw earth can be stabilized with hydraulic binders, mixed by fibers, or hyper-compacted in order to improve its mechanical behaviour. Moreover, raw earth is characterized by a low thermal conductivity what make it a good thermal insulator, and it has a very important capacity to condense and evaporate relative humidity. In this context, many researches have been developed. They have shown that the mechanical characteristics of earth materials increase with the hyper-compaction and adding fibers or hydraulic binders. Besides, other researches have been determined the thermal and hygroscopic properties of raw earth. They have shown that this material able to contribute to moisture and heat control in constructions. Its hygrothermal properties are better than fired earth bricks and concrete. The aim of this study is to evaluate the thermal and hygrometric behavior of raw earth material using experimental tests allows to determine the main Hygrothermal properties such as the water Vapour permeability and thermal conductivity and compare the results with those of other building materials such as fired clay bricks and cement concrete is presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=raw%20earth%20material" title="raw earth material">raw earth material</a>, <a href="https://publications.waset.org/abstracts/search?q=hygro-thermal" title=" hygro-thermal"> hygro-thermal</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20conductivity" title=" thermal conductivity"> thermal conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20vapour%20permeability" title=" water vapour permeability"> water vapour permeability</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20materials" title=" building materials"> building materials</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20materials" title=" building materials"> building materials</a> </p> <a href="https://publications.waset.org/abstracts/143371/hygrothermal-properties-of-raw-earth-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143371.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">175</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1348</span> Nonlinear Internal Waves in Rotating Ocean</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20A.%20Ostrovsky">L.

Stepanyants</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Effect of Earth rotation on nonlinear waves is a practically important and theoretically challenging problem of fluid mechanics and geophysics. Whereas the large-scale, geostrophic processes such as Rossby waves are a classical object of oceanic and atmospheric physics, rotation effects on mesoscale waves are not well studied. In particular, the Coriolis force can radically modify the behavior of nonlinear internal gravity waves in the ocean having spatial scales of 1-10 kilometers and time durations of few hours. In the last decade, such a non-trivial behavior was observed more than once. Similar effects are possible for magnetic sound in the ionosphere. Here we outline the main physical peculiarities in the behavior of nonlinear internal waves due to the rotation effect and present some results of our recent studies. The consideration is based on the fourth-order equation derived by one of the authors as a rotation-modified Korteweg–de Vries (rKdV) equation which includes two types of dispersion: one is responsible for the finiteness of depth as in the classical KdV equation; another is due to the Coriolis effect. This equation is, in general, non-integrable; moreover, under the conditions typical of oceanic waves (positive dispersion parameter), it does not allow solitary solutions at all. In the opposite case (negative dispersion) which is possible for, e.g., magnetic sound, solitary solutions do exist and can form complex bound states (multisoliton). Another non-trivial properties of nonlinear internal waves with rotation include, to name a few, the ‘terminal’ damping of the initial KdV soliton disappearing in a finite time due to radiation losses caused by Earth’s rotation, and eventual transformation of a KdV soliton into a wave packet (an envelope soliton). The new results to be discussed refer to the interaction of a soliton with a long background wave. It is shown, in particular, that in this case internal solitons can exist since the radiation losses are compensated by energy pumping from the background wave. Finally, the relevant oceanic observations of rotation effect on internal waves are briefly described. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Earth%20rotation" title="Earth rotation">Earth rotation</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20waves" title=" internal waves"> internal waves</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20waves" title=" nonlinear waves"> nonlinear waves</a>, <a href="https://publications.waset.org/abstracts/search?q=solitons" title=" solitons"> solitons</a> </p> <a href="https://publications.waset.org/abstracts/28004/nonlinear-internal-waves-in-rotating-ocean" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28004.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">672</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1347</span> Extracting the Atmospheric Carbon Dioxide and Convert It into Useful Minerals at the Room Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muthana%20A.%20M.%20Jamel%20Al-Gburi">Muthana A.

In our present research project, we constructed our own system to extract carbon dioxide directly from the atmospheric air at the room conditions and investigated how to convert the gas into a useful mineral or Nano scale fibers made of carbon by using several chemical processes and chemical reactions leading to a valuable building material and also to mitigate the environmental negative change. In the present water pool system (Carbone Dioxide Domestic Extractor), the ocean-sea water was used to dissolve the CO2 gas from the room and converted into carbonate minerals by using a number of additives like shampoo, clay and MgO. Note that the atmospheric air includes CO2 gas has circulated within the sea water by air pump connected to a perforated tubes fixed deep on the pool base. Those chemical agents were mixed with the ocean-sea water to convert the formed acid from the water-CO2 reaction into a useful mineral. After we successfully constructed the system, we did intense experiments and investigations on the CO2 gas reduction level and found which is the optimum active chemical agent to work in the atmospheric conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=global%20warming" title="global warming">global warming</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20gas" title=" CO₂ gas"> CO₂ gas</a>, <a href="https://publications.waset.org/abstracts/search?q=ocean-sea%20water" title=" ocean-sea water"> ocean-sea water</a>, <a href="https://publications.waset.org/abstracts/search?q=additives" title=" additives"> additives</a>, <a href="https://publications.waset.org/abstracts/search?q=solubility%20level" title=" solubility level"> solubility level</a> </p> <a href="https://publications.waset.org/abstracts/166931/extracting-the-atmospheric-carbon-dioxide-and-convert-it-into-useful-minerals-at-the-room-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166931.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">80</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1346</span> Influence of Long-Term Variability in Atmospheric Parameters on Ocean State over the Head Bay of Bengal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anindita%20Patra">Anindita Patra</a>, <a href="https://publications.waset.org/abstracts/search?q=Prasad%20K.%20Bhaskaran"> Prasad K. Bhaskaran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The atmosphere-ocean is a dynamically linked system that influences the exchange of energy, mass, and gas at the air-sea interface. The exchange of energy takes place in the form of sensible heat, latent heat, and momentum commonly referred to as fluxes along the atmosphere-ocean boundary. The large scale features such as El Nino and Southern Oscillation (ENSO) is a classic example on the interaction mechanism that occurs along the air-sea interface that deals with the inter-annual variability of the Earth’s Climate System. Most importantly the ocean and atmosphere as a coupled system acts in tandem thereby maintaining the energy balance of the climate system, a manifestation of the coupled air-sea interaction process. The present work is an attempt to understand the long-term variability in atmospheric parameters (from surface to upper levels) and investigate their role in influencing the surface ocean variables. More specifically the influence of atmospheric circulation and its variability influencing the mean Sea Level Pressure (SLP) has been explored. The study reports on a critical examination of both ocean-atmosphere parameters during a monsoon season over the head Bay of Bengal region. A trend analysis has been carried out for several atmospheric parameters such as the air temperature, geo-potential height, and omega (vertical velocity) for different vertical levels in the atmosphere (from surface to the troposphere) covering a period from 1992 to 2012. The Reanalysis 2 dataset from the National Centers for Environmental Prediction-Department of Energy (NCEP-DOE) was used in this study. The study signifies that the variability in air temperature and omega corroborates with the variation noticed in geo-potential height. Further, the study advocates that for the lower atmosphere the geo-potential heights depict a typical east-west contrast exhibiting a zonal dipole behavior over the study domain. In addition, the study clearly brings to light that the variations over different levels in the atmosphere plays a pivotal role in supporting the observed dipole pattern as clearly evidenced from the trends in SLP, associated surface wind speed and significant wave height over the study domain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20temperature" title="air temperature">air temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=geopotential%20height" title=" geopotential height"> geopotential height</a>, <a href="https://publications.waset.org/abstracts/search?q=head%20Bay%20of%20Bengal" title=" head Bay of Bengal"> head Bay of Bengal</a>, <a href="https://publications.waset.org/abstracts/search?q=long-term%20variability" title=" long-term variability"> long-term variability</a>, <a href="https://publications.waset.org/abstracts/search?q=NCEP%20reanalysis%202" title=" NCEP reanalysis 2"> NCEP reanalysis 2</a>, <a href="https://publications.waset.org/abstracts/search?q=omega" title=" omega"> omega</a>, <a href="https://publications.waset.org/abstracts/search?q=wind-waves" title=" wind-waves"> wind-waves</a> </p> <a href="https://publications.waset.org/abstracts/59933/influence-of-long-term-variability-in-atmospheric-parameters-on-ocean-state-over-the-head-bay-of-bengal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59933.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">225</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1345</span> Tectonic Movements and Ecosystems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arvind%20Kumar%20Trivedi">Arvind Kumar Trivedi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Our Earth is dynamic in nature and its structure behaves like a puzzle because the interior of the Earth is in both gaseous as well as molten (liquid) form and the crust i.e. the outermost surface is in solid form. This Earth was one landmass known as ‘Pangaea’ in the beginning. With time due to complex phenomena of tectonic movements, it was broken into various landmasses along with water bodies. This Pangaea was in direct contact with the atmosphere playing dominant role in creating various ecosystems on the Earth. Ecosystems mean: Eco (environment body) and systems (interdependent complex of all the organisms interacting with each other).

B. Karu Jayasundara</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Earth’s gravity is not uniform. The satellite imageries of the Earth’s surface from NASA reveal a number of different gravity anomaly regions all over the globe. When the moon rotates around the earth, its gravity has a major physical influence on a number of regions on the earth. This physical change can be seen by the tides. The tides make sea levels high and low in coastal regions. During high tide, the gravitational force of the Moon pulls the Earth’s gravity so that the total gravitational intensity of Earth is reduced; it is further reduced in the low gravity regions of Earth. This reduction in gravity helps keep the suspended particles such as dust in the atmosphere, sand grains in the sea water for longer. Dramatic differences can be seen from the floating dust in the low gravity regions when compared with other regions. The above phenomena can be demonstrated from experiments. The experiments have to be done in high and low gravity regions of the earth during high and low tide, which will assist in comparing the final results. One of the experiments that can be done is by using a water filled cylinder about 80 cm tall, a few particles, which have the same density and same diameter (about 1 mm) and a stop watch. The selected particles were dropped from the surface of the water in the cylinder and the time taken for the particles to reach the bottom of the cylinder was measured using the stop watch. The times of high and low tide charts can be obtained from the regional government authorities. This concept is demonstrated by the particle drop times taken at high and low tides. The result of the experiment shows that the particle settlement time is less in low tide and high in high tide. The experiment for dust particles in air can be collected on filters, which are cellulose ester membranes and using a vacuum pump. The dust on filters can be used to make slides according to the NOHSC method. Counting the dust particles on the slides can be done using a phase contrast microscope. The results show that the concentration of dust is high at high tide and low in low tide. As a result of the high tides, a high concentration of heavy minerals deposit on placer deposits and dust particles retain in the atmosphere for longer in low gravity regions. These conditions are remarkably exhibited in the lowest low gravity region of the earth, mainly in the regions of India, Sri Lanka and in the middle part of the Indian Ocean. The biggest heavy mineral placer deposits are found in coastal regions of India and Sri Lanka and heavy dust particles are found in the atmosphere of India, particularly in the Delhi region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gravity" title="gravity">gravity</a>, <a href="https://publications.waset.org/abstracts/search?q=minerals" title=" minerals"> minerals</a>, <a href="https://publications.waset.org/abstracts/search?q=tides" title=" tides"> tides</a>, <a href="https://publications.waset.org/abstracts/search?q=moon" title=" moon"> moon</a>, <a href="https://publications.waset.org/abstracts/search?q=costal" title=" costal"> costal</a>, <a href="https://publications.waset.org/abstracts/search?q=atmosphere" title=" atmosphere"> atmosphere</a> </p> <a href="https://publications.waset.org/abstracts/111250/the-gravitational-impact-of-the-sun-and-the-moon-on-heavy-mineral-deposits-and-dust-particles-in-low-gravity-regions-of-the-earth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111250.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">128</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1342</span> The Ocean at the Center of Geopolitics: Between an Overflowing Land and an Under-Exploited Sea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ana%20Maria%20De%20Azevedo">Ana Maria De Azevedo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We are living a remarkable period, responsible for the thriving of the human population to unprecedented levels. Still, it is empirically obvious that sustaining such a huge population puts a tremendous pressure on our planet. Once Land resources grow scarcer, there is a mounting pressure to find alternatives to support basic human needs elsewhere. Occupying most of our planet, it’s therefore natural that, is not a so distant future, humankind look for such basic subsistence means at the Ocean. Thus, once the Ocean becomes essential to Human subsistence, it is predictable it's moving to the foreground of Geopolitics. Both future technologies and uses of the Ocean, as bidding for the exploration of its resources away from the natural territory of influence of a Country, are susceptible of raising the risk of conflict between traditional political adversaries and/or the dilemma of having to balance economic interests, with various security and defense concerns. Those empirical observations suggest the need to further research on this perspective shift of the main Geopolitical axis to the Ocean, the new sources of conflict that can result thereon, and how to address them. The author suggests a systematic analysis of this problematic, to attain a political and legal international consensus, namely on what concerns updating of the 'United Nations Convention on the Law of the Sea' of 10 December 1982, and/or its annexes. To proceed with the present research, the primary analysis was based on a quantitative observation, but reasoning thereon relied essentially on a qualitative process of prospective scenarios assessment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=marine%20resources" title="marine resources">marine resources</a>, <a href="https://publications.waset.org/abstracts/search?q=ocean%20geopolitics" title=" ocean geopolitics"> ocean geopolitics</a>, <a href="https://publications.waset.org/abstracts/search?q=security%20and%20defense" title=" security and defense"> security and defense</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title=" sustainable development"> sustainable development</a> </p> <a href="https://publications.waset.org/abstracts/96659/the-ocean-at-the-center-of-geopolitics-between-an-overflowing-land-and-an-under-exploited-sea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96659.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">154</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1341</span> Dilation Effect on 3D Passive Earth Pressure Coefficients for Retaining Wall </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khelifa%20Tarek">Khelifa Tarek</a>, <a href="https://publications.waset.org/abstracts/search?q=Benmebarek%20Sadok"> Benmebarek Sadok</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The 2D passive earth pressures acting on rigid retaining walls problem has been widely treated in the literature using different approaches (limit equilibrium, limit analysis, slip line and numerical computation), however, the 3D passive earth pressures problem has received less attention.

The objective of this paper is to outline how the thermal performance of rammed earth walls compares to conventional reinforced concrete skeleton and red brick in-fill walls. For this sake, the indoor temperature and relative humidity of a classroom built with rammed earth walls and a vaulted red brick roof in the area of Behbeit, Giza, Egypt were measured hourly over 6 months using smart sensors. These parameters for the rammed earth walls were later also compared against the values obtained using a 'DesignBuilder v5' model to verify the model assumptions. The thermal insulation of rammed earth walls was found to be 30% better than this of the redbrick infill, and the recorded data were found to be almost 90% similar to the modelled values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rammed%20earth" title="rammed earth">rammed earth</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20insulation" title=" thermal insulation"> thermal insulation</a>, <a href="https://publications.waset.org/abstracts/search?q=indoor%20air%20quality" title=" indoor air quality"> indoor air quality</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20builder" title=" design builder"> design builder</a> </p> <a href="https://publications.waset.org/abstracts/99687/a-comparison-between-modelled-and-actual-thermal-performance-of-load-bearing-rammed-earth-walls-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99687.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1339</span> Utilizing Google Earth for Internet GIS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Derambakhsh">Alireza Derambakhsh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this examination is to explore the capability of utilizing Google Earth for Internet GIS applications.

Theoretical implications of the study are that the Gaia (Earth) Education Philosophy could serve as a strong foundation for educating young learners.it present a unique approach that promotes connections with Earth-principles and lessons that can contribute to the development of social and environmental consciousness among children and help educate generations to come into a stable and balanced future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earth%20science" title="earth science">earth science</a>, <a href="https://publications.waset.org/abstracts/search?q=nature%20education" title=" nature education"> nature education</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=gaia" title=" gaia"> gaia</a>, <a href="https://publications.waset.org/abstracts/search?q=forest%20school" title=" forest school"> forest school</a>, <a href="https://publications.waset.org/abstracts/search?q=nature" title=" nature"> nature</a>, <a href="https://publications.waset.org/abstracts/search?q=inspirational%20teaching%20and%20learning" title=" inspirational teaching and learning"> inspirational teaching and learning</a> </p> <a href="https://publications.waset.org/abstracts/173514/gaia-earth-education-philosophy-a-journey-back-to-the-future" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173514.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">65</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1336</span> Fused Salt Electrolysis of Rare-Earth Materials from the Domestic Ore and Preparation of Rare-Earth Hydrogen Storage Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeong-Hyun%20Yoo">Jeong-Hyun Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanjung%20Kwon"> Hanjung Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Wook%20Cho"> Sung-Wook Cho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fused salt electrolysis was studied to make the high purity rare-earth metals using domestic rare-earth ore. The target metals of the fused salt electrolysis were Mm (Misch metal), La, Ce, Nd, etc. Fused salt electrolysis was performed with the supporting salt such as chloride and fluoride at the various temperatures and ampere. The metals made by fused salt electrolysis were analyzed to identify the phase and composition using the methods of XRD and ICP. As a result, the acquired rare-earth metals were the high purity ones which had more than 99% purity. Also, VIM (vacuum induction melting) was studied to make the kg level rare-earth alloy for the use of secondary battery and hydrogen storage. In order to indentify the physicochemical properties such as phase, impurity gas, alloy composition and hydrogen storage, the alloys were investigated. The battery characteristics were also analyzed through the various tests in the real production line of a battery company. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=domestic%20rare-earth%20ore" title="domestic rare-earth ore">domestic rare-earth ore</a>, <a href="https://publications.waset.org/abstracts/search?q=fused%20salt%20electrolysis" title=" fused salt electrolysis"> fused salt electrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=rare-earth%20materials" title=" rare-earth materials"> rare-earth materials</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20storage%20alloy" title=" hydrogen storage alloy"> hydrogen storage alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20battery" title=" secondary battery"> secondary battery</a> </p> <a href="https://publications.waset.org/abstracts/17072/fused-salt-electrolysis-of-rare-earth-materials-from-the-domestic-ore-and-preparation-of-rare-earth-hydrogen-storage-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17072.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">533</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1335</span> Dynamic Active Earth Pressure on Flexible Cantilever Retaining Wall</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Snehal%20R.%20Pathak">Snehal R.

In present paper, dynamic active earth pressure and displacement of flexible cantilever retaining wall has been evaluated analytically using 2-DOF mass-spring-dashpot model by incorporating both wall and backfill properties. The effect of wall flexibility on dynamic active earth pressure and wall displacement are studied and presented in graphical form. The obtained results are then compared with the various conventional methods, experimental analysis and also with PLAXIS analysis. It is observed that the dynamic active earth pressure decreases with increase in the wall flexibility while wall displacement increases linearly with flexibility of the wall. The results obtained by proposed 2-DOF analytical model are found to be more realistic and economical. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earth%20pressure" title="earth pressure">earth pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake" title=" earthquake"> earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=2-DOF%20model" title=" 2-DOF model"> 2-DOF model</a>, <a href="https://publications.waset.org/abstracts/search?q=Plaxis" title=" Plaxis"> Plaxis</a>, <a href="https://publications.waset.org/abstracts/search?q=retaining%20walls" title=" retaining walls"> retaining walls</a>, <a href="https://publications.waset.org/abstracts/search?q=wall%20movement" title=" wall movement "> wall movement </a> </p> <a href="https://publications.waset.org/abstracts/32549/dynamic-active-earth-pressure-on-flexible-cantilever-retaining-wall" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32549.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">540</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1334</span> A Study on Finite Element Modelling of Earth Retaining Wall Anchored by Deadman Anchor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20S.%20Chai">K.
