Science Fiction Investigation Essay
Have you ever wondered how long earth will exist in a livable state before it is not suitable for humans anymore? Many may have asked this question, as well as had the thought of ‘Where will everyone go?’ Supposedly in the movie Elysium, it is possible for humans to live in space on a man-made floating land. Elysium has many superhuman scenes that would never be possible in real life, however, according to science there are some aspects that may be realistic in the future.
So the question is, can humans live somewhere other than planet earth and what would happen to the human body on another planet? In the movie Elysium, Earth had become very polluted and overpopulated and as a result, the upper-class rich people moved to a large place in Earth's orbit called “Elysium.” While back

Titanium and its alloys are used in various applications due to their desirable properties. One of the main sectors where titanium is highly used is in biomedical applications where both implants and tools for surgery make use of this element due to its biocompatibility, low modulus and excellent corrosion resistance. However titanium shows poor tribological properties and therefore it is generally alloyed and undergoes a surface modification to obtain the optimum requirements needed. Biomedical implants are subjected to high clinical requirements, hence before implantation in the human body, a surface modification process is carried out. The aim of carrying such modifications include; to sterilize the implant surface form contaminants before implantation, to increase the bioactivity, increase hardness and hence promotes the reduction in the implant wear rate and the introduction of a passive layer to minimize the ion release in the body.1
Despite these advantages there are concerns which affect patient’s and surgeon’s decision to undertake metal-on-metal hip resurfacing arthroplasty. These issues range from being technically demanding, stringent patient selection criteria (11), high early incidence of femoral neck fractures(12, 13) and reported risk of high circulating metal ions(14-17). There are theoretical concerns about cancers following exposure to high levels of cobalt and chromium ions (18).
Hip implants have been utilized even longer than metal-on-plastic implants. Metal-on-Metal bearings (cobalt chromium alloy, titanium alloy or from time to time stainless steel) were in use from as distant back as 1955 nevertheless they were not agreed for use in the U.S. by the FDA till 1999. They proposal the possible for considerably decreased wear, alongside less inflammation and less bone loss. A little mechanism recalls have held negative attention to Metal-on-Metal. Metal-on-metal constituents permit the biggest heads across the whole scope of implant sizes. Colossal ball heads furnish increased scope of gesture and larger stability, that can considerably cut the chance of hip dislocation, a critical factor in the long word accomplishment of an implant.
President George Washington chose a 100 mile triangular piece of land between the Potomac and Anacostia Rivers to be the site of the newly formed nation’s capital (Pohl). One reason this location was chosen was because of two thriving ports already existing in nearby Georgetown, Maryland and Alexandria, Virginia (Washington.org). The shipping trade would be very important for the city’s growth and stability. Another reason, this location put the new capital between the northern states and the southern states. Some citizens were already divided so this site provided a location
Alumina and zirconia ceramics have been widely used in orthopaedic hip replacements for the past 30 years. The advantage of using these was lower wear rates than those observed using polymers and metals. Because of the ionic bonds and chemical stability of ceramics, they are relatively biocompatible and therefore more preferable to use than metals and polymers. Alumina is most commonly used as a femoral head component instead of a metal in a hip prosthesis because this would reduce the polyethylene wear that is generated. Alumina is a desirable biomaterial to use in hard tissue implants because of characteristics like excellent wear resistance, high hardness, bio inert, low abrasion rate and good frictional behaviour. Furthermore, it has excellent surface finish as well as high fatigue streng...
Holmium is a chemical element and is the sixty seventh element on the periodic table. It is located in Period six and it is a member of the lanthanide group. It was discovered in 1879 by a Swedish chemist named Per Theodor Cleve. Like Carl Gustaf Monsander who discovered the elements lanthanum, erbium and terbium Theodor also used similar strategy's to find contaminants in the oxides of uncommon earth elements. He first looked at the oxide of erbium and was able to split it into two types of materials one being brown and the other green. This in turn caused Theodor to find the oxide of holmium (it was the brown material which is known as holmia) and this was how the element holmium was discovered.
El Cordobés, also known as Manuel Benítez Pérez, is a Spanish bullfighter known for the quality of his strategy that was balanced by his outstanding reflexes, fearlessness, and crowd appeal.
The capital of Washington is Olympia, thought that was not always its name. In fact, for four years between the founding of Olympia, 1846, and 1850, Olympia was called Smithster, named after two people named Smith and Sylvester who were early inhabitants of Olympia. The name was changed because of the scenic Olympic Mountains creating a nice view north of the city. In 1853, Isaac Stevens appeared as Washington's first territorial governor. Isaac seemed to be a very bright man, and very able. He was first in his class in graduation, and he proved himself to be hardworking and able to handle many tasks given to him at the same time. Truly a first governor to be proud of, even if he was a little short. The current capitol building of Olympia did not appear until 1928, but the one before it was built from 1880 to 1882 and served as the town's courthouse until 1905, when it was made the Capitol building.

These kinds of polymers have both some advantages and disadvantages. Although they are bioactive and biodegradable and provide high comppressive strength, Degradation of such polymers leads to undesired tissue response due to producing acid formation in degradation process. Metallic scaffolds are another method for bone repair and regenaration. They provide high compressive strength and enormous permanent strength. Metallic scaffolds are mainly made of titanium and talium metals. The main disadvantages of metallic scaffolds are not biodegradable and also discharge metal ions. Recent studies in metallic scaffolds mainly focus on biodegradable materials which can be used improve bioactivity of metals such as titanium.
A tampering rod through the head is how 25-year-old Phineas Gage became the most notable case of Traumatic Brain injury of the 19th century. With more than 1.7 million people each year who sustain an injury, why does this one case become so interesting? The reason behind this is the result of the injury. When Gage had the tampering rod penetrate his skull it completely changed his personality. From a once mild mannered individual to a foul mouth and persistent person, Gage became interesting cases in history. Gage starts us off with our topic of Traumatic Brain Injury (TBI) because in the US there are around 50,000 deaths, 270,000 hospitalizations, and 1.36 million who are treated and released to go home (Alzheimers Organization, 2014). A TBI is defined when an external mechanical force causes brain dysfunction.
As a creator of mankind, Prometheus the titan wanted the best for the human race; however, he was still under the control of Zeus. Made from clay, humans roam around Earth learning from Prometheus the ways of life which may seem like a utopia, yet Prometheus has an obsession trying to evolve humans from lowly animals to the superior race. Prometheus, who is so focused, wanted to bestow the light of fire to his works of arts; however, before the deed, Prometheus had given a proffer of playful depravity to Zeus. The raged god had declined the request of gifting humans with fire, while Prometheus mutinously went ahead and showed the human race with the beauty and dangers of fire. From Olympus, Zeus discovered the tumult
The book of Jubilees is an ancient text that was found in the Qumran caves as well as many other Dead Sea Scrolls. Approximately fifteen Jubilee scrolls were found in different caves (two each in Caves 1 and 2, one in Cave 3, nine in Cave 4, and one in Cave 11). These manuscripts contain important information about the stories that we traditionally see in Genesis and beginning of Exodus. However, the book of Jubilees is not included in the Bible because it is considered a retelling of the stories that already existed in the two books of the Bible but written in a different context. In addition, the book of Jubilees is also known as the lesser genesis or the book of the division of times is “a retelling of the stories in Genesis and the first
Earth has served as a good home for humans for many years, and will most likely
Within the andragogical model described by Knowles, Holton, and Swanson (2015), adults need learning experiences that are different than those found in the pedagogical model. Instead of waiting for experiences that are directed and controlled by a teacher, adults need to have a clear rationale and understanding for the learning, feel past experiences are valuable, and have a developed internal system for motivation in order to help a learning experience be successful. The connection and orientation to the learning task, the readiness to learn, and self-concept are other important ideas to adult learning.
