RES Subglacial Mapping for Extraterrestrial Colonization

RES Subglacial Mapping for Extraterrestrial Colonization RES Subglacial Mapping Used to Assess Extraterrestrial Colonization Eric Phelan Successful colonization of another planet involves countless variables being addressed prior to mission launch. Water, being essential to sustaining human life, must be available in sizable quantities in order to establish a fruitful, long-term colony. But even with water filtration systems operating at one hundred percent efficiency, a viable native source of water must be identified on the planet if the colony is ever expected to prosper. Radio Echo Sounding may provide a solution to this problem. Introduction Radio Echo Sounding, Ice Penetrating Radar, or more commonly Radioglaciology, has been used for many years to map the subsurface of glaciers all across the globe. From massive canyons to pockets of trapped volcanic ash, RES has been a valuable tool in understanding how glaciers form and what they contain. In more recent years, studies have been conducted on the identification of subglacial lakes. These results may prove valuable when locating viable and continuous sources of water on otherwise desolate planets. We have already identified large ice caps on Mars [1] and that Jupiter’s Satellite, Europa, is covered in water ice [2]. We have even discovered small pockets of ice in craters on the moon [3]. The issue is that we must somehow extract usable water from these locations. It would be too costly and inefficient to continuously melt ice for use, so the next option is to identify pockets of fresh water in the ice. Radioglaciology gets us one step closer to identifying ideal colony locations by first locating large subglacial lakes. These subsurface fresh water bodies could provide just enough water for a colony to grow steadily and flourish. While scientists utilize RES here on Earth, we get one step closer to colonization of other planets. Greenland: Beneath the Ice As early as 1964, advanced RES techniques were being used in Greenland to map the subsurface beneath the mile thick ice sheet. [4] Just last year, RES surveys helped make a discovery of massive proportions. A canyon 50 percent longer than Arizona’s Grand Canyon was discovered snaking its way north toward Petermann Glacier [5][6]. This allowed scientists to extrapolate subsurface river data proving that looking beneath the surface of the ice on our own world delivers extremely valuable information that we otherwise would have failed to acquire. If we can find ancient river systems and lakes on Earth using this technique, it should be viable on other planets. Antarctica: The Hostile Habitat As more research teams explore Antarctica, the use of RES surveying is becoming more extensive. The concept that is being tested here is that liquid water can form beneath these ice sheets due to the bed being above water’s pressure melting point. These surveys have found 379 lakes in Antarctica nearly 4000 meters beneath the ice [7]. While scientists are currently more interested in finding life that miraculously escaped extinction 35 million years ago, these lakes also are important in determining whether other planets may have enough liquid water housed in their ice caps to support a human population. Although the popular and most commonly used methodology of RES surveys employs airplanes with radio equipment, satellites are also viable tools for the job. A satellite deployed in orbit around a planet can map elevation changes in ice sheets that are indicative of subsurface water movements. The more movements there are, the more active the lakes and rivers are beneath the surface. Knowing this can help us determine whether lakes are replenishing quickly or have a limited source of water. As Antarctica is arguably the most hostile surface environment on Earth, it is a good training ground for setting up an extraterrestrial colony. Exposure to the inclement weather can cause irreversible damage to the human body within minutes, testing the boundaries of what our technology and potential colonists can handle. Establishing drilling projects to extract water from these subglacial lakes may be the natural â€Å"next step† in determining our capacity to survive on other planets. If we can manage to transport liquid water from 2.5 miles beneath the surface to an outpost above, we will have tested and proved a technology that could someday be used on other worlds. Space Colonization Figure 3: Artist’s conception of a moon base http://en.wikipedia.org/wiki/Space_colonization The moon is a likely first candidate for space colonization. With the discovery of large concentrations of frozen water in deep craters on the moon in 2009 [3], humanity may have more incentive than ever before to establish a colony there. With the ability to find pockets of water in these ice pits, we are well on our way to finding a viable location on the lunar surface to establish a new home. RES surveys of the moon can be conducted from Earth’s surface, but for greater resolution we must get closer. Placing RES satellites in orbit around the moon would allow us to pinpoint liquid water access spots. The same technique would be viable on Mars and, eventually, Europa. If we can establish a stable colony on the moon first, though, we will be one step closer to reaching our full potential as a species. Conclusion The number of planets out in space is immeasurable. If only a fraction of them had water ice on the surface, it would open us up to countless possibilities. With the advancement of RES technologies, we will one day be able to detect water in places that we would have otherwise missed. Finding pockets of water buried deep beneath the ice on Mars or Europa using RES techniques would go a long way toward expanding humanity’s reach into the known universe. We could finally establish colonies on planets that were once thought to be impossible to access. It may be the stuff of science fiction today, but someday in the future this data will be used by engineers and architects to plan out large scale cityscapes that support thousands of lives. It would be the dawn of a new golden age for human civilization, and all of it made possible through the advancement of RES technologies.

Fidel Castro Essay -- essays research papers

Biography of Fidel Castro Fidel Castro was born on August 14, 1927 in Mayari, Cuba. His parents were relatively wealthy and owned a sugarcane plantation. During his childhood, he attended private Catholic Schools and graduated to attend the University of Havana in 1945. His teachers immediately noticed Fidel's amazing memory, which he used to memorize entire books. At the university, he majored in law studies and became a member of several groups that opposed the Cuban regime, aiding exiles from the Dominican Republic in their political movement. The Cuban government dissolved the group in 1947 and Fidel joined in protests in Bogota that were intended to stop the Ninth International Conference of American States. He graduated with his degree in law in 1950 and had seen the power of political movements. He became a full member of the Ortodoxo Party and campaigned for a seat in the Cuban Congress. However, his plans were disrupted when Fulgencio Batista seized control of the Cuban government in order to prevent the rise of the Orthodoxos. Under Batista, thousands of political opponents were murdered and the people were held under massive oppression. He began plotting militant action against the Batista regime, becoming the leader of nearly 200 revolutionaries from all over Cuba. On July 26, 1953, he led them in a guerilla attack on the Moncada army barracks in Santiage de Cuba. The militia seized weapons and other supplies and their success caused the citizens there to rally...

Child Study Report Essay

Introduction Early childhood educators play an important role in observing, recognizing, and supporting children’s development (Charlesworth, 2014). In this report, child E has been chose to be observed with different observing methods including running record, anecdotal record and learning story. Child E is a 3 years old boy. His father is a New Zealander, and his mother is from China. He is the only child in his family. Child E dose not speak Chinese but only English, this is due to the reason that both his parents speak English at home and his mother does not want him to learn Chinese. Child E was born in New Zealand and he dose not know much about Chinese cultural. He attends at the center five days per week. His mother often drops him in the morning around 10am and the father picks him up around 6pm. Moreover, child E has just been transferred from the toddler room to the pre-school room two weeks ago. Child E and I know each other in the toddler room. In my report, I will focus on physical and socio-emotional developments and link them with development theories and concepts. I will also discuss how these two domains inter-related to the children’s holistic development. Read more: Factors that influence child development essay Physical Development Physical development is an essential domain that is extremely important for children’s development. The physical development of child E can be seen in all the observations. G. Stanley Hall and Arnold Gesell developed Maturation theory. According to the theory, maturation and growth occur together and they are interrelated. In another word, while a child is physically growing up, the nature and quality are changing as well. â€Å"Growth is what happens; maturation is how it happens† (Gordon and Browne, 2014). Furthermore, Gessell transferred his ideas of maturational process into the developmental milestones. The milestones indicate a child’s ability achievement at a certain age (Petty, 2010). The developmental milestone is a useful tool for early childhood teachers due to the reason that teachers can know what a child should achieve at specific ages. This can help teachers to plan and implement learning experiences for children. Also, the physical growth and deve lopment are closely related to children’s essential health and wellbeing  (New Zealand Tertiary College [NZTC], 2014). The physical experience supports children’s motor skills development. Using touching as an example, in observation one, child E patted the teacher and other children to get their attention. Instead of hitting or grabbing hardly, he patted gently. Child E experienced and developed the skill of controlling his motor when touching other people. Moreover, it is stressed in Te WhÄ riki (Ministry of Education [MoE], 1996), although there is a pattern of learning and development, teacher should see each child as an individual and every child follows their own rate of development. Thus, the physical development is not always predictable. To further explain this, in observation one, the action of poking shows the skill of using fine and gross motor. Child E and children J both can poke with the brush well, but their ages are different. In observation three, all the children joined the activity (musical statues) are 3 or 4 years old. They have different levels of balancing skills. In addition, Freud’s psychosexual stages also indicate deferent stages’ main development. He stressed the daily events and experience help children’s physical development in every stage (Berger, 2001). Child E is learning and developing his physical skills in every day life. Besides the theories discussed above, there are also some other factors that influence children’s physical development. Genetic make-up is the internal factors, and there are external factors include nutrition, exercise, social-cultural context, family care and health care services (NZTC, 2014). Genetic factors have impacts on many areas of development. In observation two, child E asked for more food is an example of his body’s natural needs. Social-cultural factor plays a significant role in the physical development. A child’s family vale and believe will influence the child. For instance, in observation two, child E left all the vegetables and only ate the rice and meat. Teachers already talked to his mother about this, and his mother believes the child know what to eat or not. She dose not want to encourage him to eat more vegetables. Instead, she asked teachers to give child E more meat. I also found that in the morning, when child E’s mother drops him at the center, E often has a chocolate muffin or other food high in sugar and fat as his breakfast. A current New Zealand research (Theodore, Thompson, Wall, Becroft, Robinson, Clark, Pryor, Wild & Mitchell, 2006) found that an  unhealthy diet would lead problems like diabetes, obesity, asthma and heart disease in young children, which will influence them a life-long time. Also, an unhealthy and unbalanced diet would cause undernourished problem of children. It has a huge impact on children’s physical development (Berk, 2013). The physical development is closely associated with other development domains. In terms of cognitive development, while children develop their fine and gross motor skills, the brain is stimulated and developed as well (Gordon & Browne, 2014). Take observation three as an example, while child E was finding his balancing with the motor skills, he also used his brain to control his gross and fine motor. Moreover, in the activity, he also used words like ‘move’ and ‘stop’ with his physical movements. His language learning was encouraged as well. Also, physical development inter-relate in relation to children’s social and emotional development, which will be discussed later. Social and emotional development Through all the four observations, child E showed his strong social skills and he was eager to communicate with others. A child’s social and emotional development is affected by both biological nature and the environment surrounds him or her. The different genetic factors and the other external factors influence children behave differently (NZTC, 2014). Building a positive relationship with children is essential for supporting emotions in young children. Supporting children’s emotions in a caring and social context can help the early childhood children to build a secure attachment relationship (Berk, 2013). It is stated in Te WhÄ riki (MoE, 1996), children will show their confidence only when they have built up the sense of belonging and secure at an environment. In observation one, child E chose to take a chair and set right next me. He is new to the pre-school environment, so he felt a little bit of insecure. He knows me from the toddler room a long time ago, so he feels emotionally safe and comfort around me. According to John Bowlby’s young children feels more comfortable around the person they attached to (Berger, 2001). Turning to Sigmund Freud’s theory, he considered personality as a key part of every child’s development. He  believes a newborn baby is governed by the id, which is the source of desire and motives that we born with (Berger, 2001). Erik Erikson further developed and modified Freud’s psychoanalytic perspective of development. Erikson sees the surrounding society as an important factor for every child. He believes that children develop from the interaction with surrounding environment, and a child and his/her environment have influence on each other (Berk, 2013). Most importantly, he added the parent-child relationship as a new interactive aspect. As we talked above, in the physical development part, child E’s mother’s believe obvious has an impact on child E’s eating habits. In the second observation, child E left all the vegetables in the bowl. This might be due to the reason that his parent’s allow him to choose what to eat at home. Different from both Freud’s and Erikson’s view, learning theorists emphasize the role of external forces in children’s social and emotional development. Behaviourism and social learning theory are the two most well-know learning theories. Behaviourism theory focuses on children’s behaviour and it sees culture as a key element of children’s learning. Behaviourism believes that environment can stimulate and elicit children’s responses (MacNaughton, 2003). From the four observations, child E was responding to his surrounding environment a lot. He was developing through interacting with his teachers, peers and toys in the environment. In the first observation, the teacher in pre-school room set up the painting activity to provide opportunities and encourage children to explore. Child E then chose to join the activity. E saw child J’s action and copied it. This is how child E learned from his surrounding environment. Social learning theory is closely linked with Behaviourism. It is because that socialization involves learning about how to behave in a social group. In social learning theory, children are active learners. They develop an understanding of self-awareness and social roles. Modeling, imitation, observation and self-efficacy are the main concepts of this theory. Children will then find out their abilities of doing a task. When they believe that they are good at the task, it is more likely they can overcome the difficulties. Otherwise, they could give up easily (Crain, 2000). In observation 2, child E was trying to keep balance. When he found out that balancing is little bit hard and his peers said he was out, he  stopped trying and felt emotionally uncomfortable. In the contrast, observation 3 shows that he was confident at building the station. Thus, when he needs to rebuild it, he did not give up. Same as physical development, Social and emotional development is also inter-related to children’s holistic development. It is emphasized in Te WhÄ riki (MoE, 1996) that a holistic curriculum is the development of a whole child in both individual and socio-cultural aspects. All the observations show how socio-emotional development and physical development happened in child E’s daily experience together. If E is emotional unwell, his physical development could be effect. Communication is an irreplaceable part of socio-emotional development, either verbal or non-verbal. Language skills are practiced through social experience. Cognitive domain is also influenced by socio-emotional development. Children’s brain is stimulated through interacting with others (Berger, 2001). Spiritual development is also a core part of holistic development. Children build up their sense of wondering and wisdom through social communication. Conclusion To sum up, I have discussed two developmental domains through analysing four observations. Child E has achieved a big improvement in both physical and socio-emotional developments. Moreover, all the developmental areas inter-related with each other, together, create a holistic curriculum for early childhood children. Reference list Berger, K. S. (2001).

Auditory Processing Disorder ( Adhd ) - 928 Words

Auditory Processing Disorder affects many children. It affects the way incoming sounds and speech are perceived and processed. Many times Auditory Processing Disorder goes undiagnosed and misdiagnosed as other disorders such as Attention Deficit Hyperactivity Disorder (ADHD). These Children will also be perceived as unintelligent. A majority of the time these children are of normal intelligence, but due to the difficulties they experience with hearing they are perceived as unintelligent. By examining and studying several sources I will be addressing basic information regarding this disorder, its characteristics, symptoms, diagnosis, and treatment. It is important to understand this disorder more fully in order to diagnose and treat these patients to the best of our abilities. By diagnosing and creating a treatment plan for the patient at a young age, we can help them overcome and learn how to live with this disorder. We are providing them all the tools necessary to live a succ essful life. â€Å"Auditory Processing Disorder is a measurable neurological defect located in the higher auditory neural pathways. Sound waves enter each ear canal and are passed through the middle ear where they are â€Å"prepared† for delivery to the cochlea (part of the inner ear).
