All About Carbon Fiber and How Its Made

All About Carbon Fiber and How It's Made Also called graphite fiber or carbon graphite, carbon fiber consists of very thin strands of the element carbon. Carbon fibers have high tensile strength and are very strong for their size. In fact, carbon fiber might be the strongest material there is. Each fiber is 5-10 microns in diameter. To give a sense of how small that is, one micron (um) is 0.000039 inches. One strand of spider web silk is usually between 3-8 microns. Carbon fibers are twice as stiff as steel and five times as strong as steel, (per unit of weight). They also are highly chemically resistant and have high-temperature tolerance with low thermal expansion. Carbon fibers are important in engineering materials, aerospace, high-performance vehicles, sporting equipment, and musical instrumentsto name just a few of their uses. Raw Materials Carbon fiber is made from organic polymers, which consist of long strings of molecules held together by carbon atoms.  Most carbon fibers (about 90 percent) are made from the polyacrylonitrile (PAN) process. A small amount (about 10 percent) are manufactured from rayon or the petroleum pitch process.  Gases, liquids, and other materials used in the manufacturing process create specific effects, qualities, and grades of carbon fiber. The highest grade carbon fiber with the best modulus properties are used in demanding applications such as aerospace. Carbon fiber manufacturers differ from one another in the combinations of raw materials they use. They usually treat their specific formulations as trade secrets. Manufacturing Process In the manufacturing process, the raw materials, which are called precursors, are drawn into long strands or fibers. The fibers are woven into fabric or combined with other materials that are filament wound or molded into desired shapes and sizes. There are typically five segments in the manufacturing of carbon fibers from the PAN process. These are: Spinning. PAN mixed with other ingredients and spun into fibers, which are washed and stretched.Stabilizing. Chemical alteration to stabilize bonding.Carbonizing. Stabilized fibers heated to very high temperature forming tightly bonded carbon crystals.Treating the Surface. ​The surface of fibers oxidized to improve bonding properties.Sizing. Fibers are coated and wound onto bobbins, which are loaded onto spinning machines that twist the fibers into different size yarns. Instead of being woven into fabrics, fibers may be formed into composites. To form composite materials, heat, pressure, or a vacuum binds fibers together with a plastic polymer. Manufacturing Challenges The manufacture of carbon fibers carries a number of challenges, including: The need for more cost-effective recovery and repair.The surface treatment process must be carefully regulated to avoid creating pits that could result in defective fibers.Close control required to ensure consistent quality.Health and safety issuesSkin irritationBreathing irritationArcing and shorts in electrical equipment because of the strong electro-conductivity of carbon fibers. Future of Carbon Fiber Because of its high tensile strength and lightweight, many consider carbon fiber to be the most significant manufacturing material of our generation. Carbon fiber may play an increasingly important role in areas such as: Energy: Windmill blades, natural gas storage, and transportation, fuel cells.Automobiles: Currently used just for high-performance vehicles, carbon fiber technology is moving into wider use.  In December 2011 General Motors announced that it is working on carbon fiber composites for mass production of automobiles.Construction: Lightweight pre-cast concrete, earthquake protection.Aircraft: Defense and commercial aircraft.  Unmanned aerial vehicles.Oil exploration: Deepwater drilling platforms, drill pipes.Carbon nanotubes: Semiconductor materials, spacecraft, chemical sensors, and other uses. In 2015, carbon fiber had a $2.25 billion market size. Projections have the market expanding to $31 billion by 2024. To accomplish this, costs must be reduced and new applications targeted.

Whole Foods case study Example | Topics and Well Written Essays - 1500 words

Whole Foods - Case Study Example Tri-component model which is expressed through sequence cognitive-affective-conative can be utelised by Whole Foods Market towards this effect. This denotes that Whole Foods Market should first engage in informing the potential customers of the importance of the organic food and then work towards lowering the prices. This can be achieved by packaging its foods into different sizes that would enable such customers afford to buy. When this is done, the feeling of affordability will be created to the customers and they will be eventually buy Whole Foods Market foods. At the end, customers would buy the recommended products and succeeed in weakening any misconception that bar them from buying the products. In fact, when a few of them get the experience of the products, they would recommend the products to other customers. However, this has to be accompanied by other complementing strategies. The company should produce high quality products and offer good customer service. Customers are c onsidered to be rational in consumption. Therefore, they tend to purchase from stores that meet their current needs. If Whole Foods Market is unable to meet different customer needs, there is a high possibility of the customers would shift to other companies offering similar products. For Whole Foods Market to be able to change some of the negative attitude of customers that bars them from buying the organic food, the company should concentrate on changing the motivation function. This can be achieved by offering cheap organic foods that would negate the customers’ misconception that organic foods are expensive. Additionally, this can be done strategically by focusing on the group that has such misconceptions with the intent of proving that Whole Foods Market foods are of high quality and affordable to all. Additionally, if the customers have a different belief that seems to

Compare Canadian Healthcare System with US Healthcare System Research Paper

Compare Canadian Healthcare System with US Healthcare System - Research Paper Example In this essay, the author will illustrate a brief descriptive analysis and critical evaluation of the considerable merits of the two systems. While, it is generally acknowledged that Canada’s system is inexpensive, others also contend that it is inferior to the US healthcare system in terms of availability and quality of care. The aim of this paper is not to prove who is better off than the other, but to offer valuable points for improvement for the greater welfare of the people. Funding. The main difference between the US and Canadian healthcare system is the way it is funded. In the US, various insurance agencies in coordination with the concerned governmental units would pay for the hospitalization and other medical expenses of the citizen, notwithstanding his or her own personal fund to cover every item in the bill (Shi & Singh, 2008). While in Canada, the government serves as the single payer for all the expenses incurred in the medical procedures of the citizen. For most cases, no charge shall be directed to the patient, although for pharmaceutical purchases a minimal amount may come from his or her own wallet. In this context, the Canadian system earns many significant advantages as the coverage is universal, and ‘less privileged’ citizens enjoy the same medical treatment as those with the wealthy members of society. Recent statistics demonstrate that life expectancy rate in Canada is higher than in the US by two years. It was noted that the latter is among the lowest among highly industrialized nations in terms of this scientific finding (Nolte & McKee, 2008). Costs. The role of the government in Canada’s healthcare system is much noticeable than in the US. The serious responsibility of the state to pay for the medical expenses of the people poses a challenge to the officials, yet places them in the position to be of much help. Available literatures declare that with Canada’s government as sole payer, efficient administ ration of healthcare costs is achieved. In the US, the multifarious insurers may actually lead to the confusion of the patient and physician, hence precipitating hitches on the way. Access. One great disadvantage to the Canadian health system, however, is the lowered number of physicians. This plight was attributed to the fact that most Canadian doctors would opt to practice the profession in the American soil as the financial rewards are way too attractive than in their homeland. This premise may also be contributory to the imbalance of the number of generalist and specialist physicians in the US. In any event, equilibrium of these medical professionals is necessitated to provide holistic medical treatment to patients. By instituting some reforms in the American set-up, generalist doctors will proliferate and will be available to the general public (Schoen, Osborn, Doty, Squires, & Applebaum, 2009). It was also reported that in the area of technological advancement in healthcare, C anada’s system is less important. Few numbers of scanner and MRI machines may cause delay in the service and would cause for insufficient diagnostic reliability. Above all, due to these reasons, Canada’s healthcare providers are criticized for the longer wait periods that their clients experience. Another negative aspect raised against both systems is the intentional inaccuracy of diagnostic results so as to generate profit.

Diversity in America Essay Example for Free

Diversity in America Essay In an ideal world, humanity would understand that all mankind is created equally; that the underlying truth of each of us is goodness, and that through awareness, conscious choice and the willingness to create positive change, we could live in a world where diversity is celebrated. We would leave behind the substantial racist and oppressing patterns that exits in this world, specifically in the United States of America. It is said that the U. S. is a melting pot of cultures, and that we are a country of immigrants existing together as a new culture, living under the values of a democracy based on freedom, liberty and the pursuit of happiness. Yet this policy is completely disregarding the fact that as immigrants, we brutally committed genocide to the Native Americans. The dominant race in the U. S. A. is made up of white Euro-centric people, and looking at the patterns that exist in this culture is important to examine the history, the ways in which racism is alive and how and who is affected. We all must look at how, as an individual and within a community, we can work towards positive change, healing and understanding. As a society, we have committed and perpetuated the oppression of different cultures specifically the Native Americans, the Native Africans and the many immigrants from different countries. In the early history of the U. S. government, it is clear that there was a systematic method that aimed to remove the Native Americans from the land that was desired by the colonists, with the malicious intention to commit genocide. The first example of the patterns of racism that were established is seen in the fabrication of stereotypes onto the Native Americans. It was said that the Natives were â€Å"barbarians† and that they would rape and murder women and children and that they â€Å"served the devil† (Tataki, 1993, p. 41). The whites held the belief that the Natives were occupying land that the colonists felt entitled to. â€Å"White people also justified the genocide by saying that Native Americans died from diseases they were biologically unable to resist† (Kivel, 2002, p.126). It is a known fact that smallpox were given to the Natives as a way to kill them. Multiple examples exist throughout the history of the whites murdering, raping and unjustly exploiting almost every aspect of the Native’s culture. After committing such horrendous violations we are left with the inability to change all that has occurred and a great sadness that produces guilt, blame and anger that often stagnates a healing process and increases denial and avoidance. The Native American population has almost completely been destroyed. â€Å"At the time Columbus arrived in the West Indies there were approximately fifteen million indigenous people†¦ today†¦ the population of native Americans in the United States is around three million according to U. S. government census figures† (Kivel, 2002, p. 124) and the remaining Natives in America are mostly confined to reservations. This small fraction of designated land is no longer their original sacred land but it is being raped for natural resources. White settlers not only committed genocide but they also enslaved the Native Americans. This pattern of entitlement and abuse was continued with the legal capturing and enslavement of people of African decent with as much violence and oppression. The history of slavery in the United States that occurred through 1619 to 1865 began soon after the English colonists first settled in Virginia and lasted until the passage of the thirteenth Amendment to the U. S. Constitution. â€Å"Over the next twenty five years Virginia passed a series of laws that legalized slavery, producing a radically subordinate and stigmatized class below that of all whites† (Kivel, 2002, p.130). Although technically slavery was abolished in1865, a linage of abuse and inhumane treatment was installed and has been carried into this day and age providing a challenge to accept and comprehend the past. In an attempt in understanding black oppression, there are aspects that demonstrate this injustice. They are institutional racism, racist knowledge and power relations that are played out in our culture and in no way have anything to do biology. Individuals and societies have created and used race as a means to oppress and overpower other groups of people. Racial oppression is when a group of people dominates another for their own benefit disregarding justice and respect through the use of violence and defining and discriminating racial differences. This dominant group receives various benefits although in the larger picture all sides loose for the continuation of a pattern of pain and injustice is insured through these actions. African-Americans are a case of this racial oppression. They were turned into slaves because of the color of their skin. It is shocking that it did not start this way and that through the power of the U. S.government slavery laws were passed that enabled the white masters to turn the blacks into slaves. This is an example of the institutional racism used to enslave the blacks. Because of this occurrence, we, as a society, must break down the residual stereotypes that have instilled fear, pain and disconnection between the races, and to change the model that exists even at this point in time. Another example of racism in the U. S. is seen in the treatment of immigrants. This subject is personal, for on my father’s side of my family I am part of the first generation born in American. My father’s parents immigrated to the U. S. , to escape the holocaust and I am sure shared the dreams of the majority of different immigrants who traveled to the â€Å"land of opportunity,† escaping places of war and economic devastation to begin and pursue a new and better life. Through the duration of attending a class studying the diversity in America I have gained painful yet poignant knowledge of the racism that is still perpetrated upon immigrants, specifically on Jewish people. I have recently learned that groups of neo-Nazis congregate and commit acts of violence against Jewish people and immigrating races. This is terrifying to me and feels unacceptable while we live under a constitution that allows personal expression but does not permit such distinct racist and violent behavior. I am grateful and saddened that because I was raised in a protected and privileged community I have rarely experienced oppression and hateful discrimination when it so readily exists in our culture. In the past few months I find myself cycling through heartbreak, anger and disbelief of the injustice that has and still occurs, and then to a yearning for healing and equality for all. I remain in a space of wonderment, questioning the fact that although laws have been installed to prevent the acts of racism, fear, ignorance and violence is bubbling hot under the surface of our society, and we are a long way from a complete shift in humanity that I crave. I do believe there is hope. I believe that in gaining the truth of the past and diminishing ignorance of the harm that was and still is being done we open a door that may aid in the battles that are still being fought. Although the brutality of racism is alive, the potential to fight for the rights of all the people who live upon this American soil is possible, but the truth of the history and the attainment of awareness must be brought to fruition.

Macbeth and Othello Essay -- Shakespeare macbeth Othello Essays

Macbeth and Othello â€Å"Upon my head they plac’d a fruitless crown And put a barren sceptre in my gripe, Thence to be wrench’d with an unlineal hand, No son of mine succeeding† (Macbeth, III.i.62) â€Å"Renew I could not like the moon† (Timon of Athens, IV.iii.68) What distinguishes Macbeth and Othello from other tragedies is the fact that their protagonists are neither fathers nor sons, mothers nor daughters. We know nothing of Macbeth or Othello’s parents, and neither of them has children. Lady Macbeth makes a passing reference to having once â€Å"given suck† and to â€Å"how tender ‘tis to love the babe that milks [her]† but never returns to the subject, and in any case, what remains impressed in one’s memory is the line that follows: â€Å"I would, while it was smiling in my face, have pluck’d my nipple from his boneless gums and dash’d the brains out, had I so sworn† (I.vii.54). Clearly, she is not the maternal type. This is reiterated a few scenes later, with her invocation of the spirits to â€Å"unsex me here and fill me from the crown to the toe topfull of direst cruelty; make thick my blood, Stop up th’access and passage to remorse [†¦] Come to my womanâ€⠄¢s breasts And take my milk for gall (I.v.40-47).† The notion of cruelty forming inside her cannot but be likened to that of the baby that would grow there if she were not â€Å"unsexed,† as if cruelty were somehow taking the place of the foetus. There is a definite sense of this in the phrase â€Å"stopping up th’ access and passage†, as if what is being insisted upon were the prevention of either sex/conception (â€Å"access†) or childbirth (â€Å"passage†). It is as if she will bear fruit to or cultivate cruelty rather than a son or daughter—one has the distinct impression of a misused womb and... ...o all the human sons do hate From forth thy plenteous bosom, poor root. [†¦] Teem with new monsters [†¦] Dry up thy marrows† (IV.iii..178-192). For this passage encapsulates everything I have discussed so far: the notion of giving birth to monsters and monstrous deeds instead of children, the idea of obstructing the possibility of a satisfying ending and denying that of continuation (â€Å"Dry up thy marrows† distinctly recalls â€Å"stopping up th’ access and passage†), of engendering death and wiping out everything but a transient present. There is the same bitter after-taste as in the other plays, as if we had partaken of the roots Timon is forced to live on, and that same exhaustion that comes from ranting and railing and coming to no satisfying conclusion. The bed is unmade, the sheets are tangled and dirty, our voices are hoarse, and we are none the better for it.

Diabetes and Nutrition

Diabetes mellitus is a continual disorder of carbohydrate and lipid metabolism in which blood levels of glucose and lipids are elevated. This abnormal metabolism results from a relative lack of insulin, either too little insulin is secreted or the insulin that is secreted is not effective. In addition, diabetes is associated with chronic systemic complications, which, over time, can affect the retina, kidneys, nerves, and cardiovascular system. The most common classifications of diabetes mellitus include type I, or insulin-dependent, diabetes mellitus (IDDM); type II, non-insulin-dependent diabetes mellitus (NIDDM); and gestational diabetes (GD).How it is DevelopedThe problems of diabetes originate in an organ located behind the stomach about the length of a human hand called the pancreas. The pancreas is necessary for both digesting food and regulating energy. It is the regulation of energy for the body that is important in the development of diabetes. The pancreas produces hormones that metabolize food. These hormones regulate the use of glucose, a simple sugar, which is used for most of the activities in our bodies. The pancreas regulates energy in a variety of behaviors in which humans engage such as exercise and movement, responding to trauma and stress, and infections.The pancreas emits three different types of hormones. Insulin is the first hormone that is produced when glucose rises in the blood. Insulin usually rises after eating a meal, and excess glucose that is not used is stimulated by insulin to be stored in muscles and fat cells so that energy can be used later. The liver also stores excess glucose in the form of a carbohydrate called glycogen. The second type of pancreatic hormone is glucagon. Glucagon breaks down glycogen stored in the liver so that it can be used as energy when blood glucose supplies are down. The third type of pancreatic hormone is called somatostatin, thought to be important in regulating both insulin and glucagon.When diabe tes develops, this balanced control system does not operate properly. The glucose in the bloodstream increases, and the cells are not able to utilize it. The individual develops hyperglycemia (excess glucose in the blood). This can be detected by measuring the glucose in the blood from a blood sample, or if the glucose is elevated enough, it can be detected in the urine as spillover. This sort of situation occurs when there is not enough insulin to permit the cells to utilize the glucose, or there is resistance most likely at the cellular level to the presence of insulin. Both cases produce diabetes.Symptoms of DiabetesSome of the symptoms of Diabetes Mellitus are increased thirst, increased urination, weight loss even though the individual is eating more, fatigue, nausea, and vomiting, skin infections, vaginitis, blurred vision, bladder infections, and impotence in men and cessation of menses in women.One severe symptom of diabetes is diabetic ketoacidosis. This symptom sometimes p roduces slightly sweet-smelling breath that is caused by acetone, a metabolic byproduct, when the body is forced to burn fatty acids rather than glucose. This process becomes more and more toxic to the body as it continues; the individual may develop diabetic coma and die. Ketoacidosis occurs when individuals are either not getting enough insulin or the insulin is not adequate to allow cells of the body to utilize the glucose.Effects of DiabetesDiabetes has two types of long-term effects. One type is associated with blood vessel involvement. Damage to the large vessels puts the diabetic at greater risk of stroke, heart attack, and gangrene of the feet. When small blood vessels are damaged, eyes, kidneys, and nerves become damaged. The other long-term effect is nerve damage usually in the feet, but also occasionally in the hands. This nerve damage is called diabetic neuropathy. This damage may cause a painful burning sensation with loss of sensation over time, making the body part mo re subject to injury and infection. Foot ulcers and gangrene can develop, with further damage in the extremities. In men, diabetic neuropathy may cause erectile impotence.Nutrition for DiabetesConsultation with a dietitian familiar with children and with type 2 diabetes is important for all patients. The dietitian should assess the nutritional status and practices of the patient and then counsel them to provide a meal plan which, at least initially, does not deviate in a major way from their usual eating practices. Changes made gradually, through subsequent appointments and interviews, frequently achieve compliance more successfully than does radical and rapid change.Individuals providing counseling must be clear about the differences in the management of patients with type 1 and type 2 diabetes. Because obesity is a typical finding in type 2 diabetes and caloric restriction results in improved glycemic control and insulin sensitivity, modest caloric restriction and weight loss or m aintenance are important goals: so is correction of the dyslipidemia, which frequently accompanies the metabolic syndrome or IRS.In general, calories from dietary fat should not exceed 30% of energy intake, and calories from saturated fat should not exceed 10%. An effort is also made to limit cholesterol in the diet to

Conflict Theory essays

Conflict Theory essays Conflict theory seems perhaps better suited to explain the contradictions in world trade and, even more profound, the differences that normally appear between developed and developing countries, especially in World Trade Organizations Ministerial Conferences, but also in general The tools and general trends that world trade operates with are liberalization and protectionism (protective measures). High import taxes and subsidies are among the most common protective measures and these have the role of protecting national producers against lower priced, more competitive products that may enter the country and may force the national The industrialized countries generally aim at imposing global lower import taxes on manufactured goods. This would ensure them better export capabilities to third world countries, given the fact that manufactured goods from developed countries are generally more competitive, because of higher prices. So, the only chance for national manufactured goods from third world countries would be a price advantage over Western goods. However, the price advantage is driven by the price level at which these goods are sold. The lower the import taxes, the lower the price that Western goods will be commercialized at and, as such, the lower the price advantage for manufactured goods n developing countries. The agricultural products are somewhat in a different situation. Many developing countries produce much cheaper goods, but this would tend to suffocate national producers in United States and the European Union, for example, because they would not be able to compete with cheaper grains, fruits, etc. As such, developed countries use either import taxes or export subsidies that will allow for lower price for the producers at which they will sell and will thus protect national farmers by ensuring they stay in business. Over these two d...

The Second Voyage of Christopher Columbus

The Second Voyage of Christopher Columbus Christopher Columbus returned from his first voyage in March 1493, having discovered the New World...although he didn’t know it. He still believed that he had found some uncharted islands near Japan or China  and that further exploration was needed. His first voyage had been a bit of a fiasco, as he had lost one of the three ships entrusted to him and he did not bring back much in the way of gold or other valuable items. He did, however, have a handful of bedraggled natives he had taken on the island of Hispaniola, and he was able to convince the Spanish crown to finance the second voyage of discovery and colonization. Preparations for the Second Voyage The second voyage was to be a large-scale colonization and exploration project. Columbus was given 17 ships and over 1,000 men. Included on this voyage, for the first time, were European domesticated animals such as pigs, horses, and cattle. Columbus’ orders were to expand the settlement on Hispaniola, convert the natives to Christianity, establish a trading post, and continue his explorations in search of China or Japan. The fleet set sail on October 13th, 1493, and made excellent time, first sighting land on November 3rd. Dominica, Guadalupe and the Antilles The island first sighted was named Dominica by Columbus, a name it retains to this day. Columbus and some of his men visited the island, but it was inhabited by fierce Caribs and they did not stay very long. Moving on, they discovered and explored a number of small islands, including Guadalupe, Montserrat, Redondo, Antigua, and several others in the Leeward Islands and Lesser Antilles chains. He also visited Puerto Rico before making his way back to Hispaniola. Hispaniola and the Fate of La Navidad Columbus had wrecked one of his three ships the year before during his first voyage. He had been forced to leave 39 of his men behind on Hispaniola, in a small settlement named La Navidad. Upon returning to the island, Columbus discovered that the men he had left had angered the native population by raping local women. The natives had attacked the settlement, slaughtering the Europeans to the last man. Columbus, consulting his native chieftain ally Guacanagarà ­, laid the blame on Caonabo, a rival chief. Columbus and his men attacked, routing Caonabo and taking many of his people as slaves. Isabella Columbus founded the town of Isabella on the northern coast of Hispaniola, and spent the next five months or so getting the settlement established and exploring the island. Building a town in a steamy land with inadequate provisions is hard work, and many of the men sickened and died. It reached the point where a group of settlers, led by Bernal de Pisa, attempted to capture and make off with several ships and go back to Spain: Columbus learned of the revolt and punished the plotters. The settlement of Isabella remained but never thrived. It was abandoned in 1496 in favor of a new site, now Santo Domingo. Cuba and Jamaica Columbus left the settlement of Isabella in the hands of his brother Diego in April, setting out to explore the region further. He reached Cuba (which he had discovered on his first voyage) on April 30 and explored it for several days before moving on to Jamaica on May 5. He spent the next few weeks exploring the treacherous shoals around Cuba and searching in vain for the mainland. Discouraged, he returned to Isabella on August 20, 1494. Columbus as Governor Columbus had been appointed governor and Viceroy of the new lands by the Spanish crown, and for the next year and a half, he attempted to do his job. Unfortunately, Columbus was a good ship’s captain but a lousy administrator, and those colonists that still survived grew to hate him. The gold they had been promised never materialized and Columbus kept most of what little wealth was found for himself. Supplies began running out, and in March of 1496 Columbus returned to Spain to ask for more resources to keep the struggling colony alive. The Start of the American Indian Slave Trade Columbus brought back many native slaves with him. Columbus, who had once again promised gold and trade routes, did not want to return to Spain empty-handed. Queen Isabella, appalled, decreed that the New World natives were subjects of the Spanish crown and therefore could not be enslaved. However, the practice of enslaving indigenous populations continued. People of Note in Columbus’ Second Voyage Ramà ³n Panà © was a Catalan priest who lived among the Taà ­no people for about four years  and produced a short but very important ethnographic history of their culture.Francisco de Las Casas was an adventurer whose son Bartolomà © was destined to become very important in the fight for native rights.Diego Velzquez was a conquistador who later became governor of Cuba.Juan de la Cosa was an explorer and cartographer who produced several important early maps of the Americas.Juan Ponce de Leà ³n would become governor of Puerto Rico but was most famous for his journey to Florida in search of the Fountain of Youth. Historical Importance of the Second Voyage Columbus’ second voyage marked the start of colonialism in the New World, the social importance of which cannot be overstated. By establishing a permanent foothold, Spain took the first steps towards their mighty empire of the centuries that followed, an empire that was built with New World gold and silver. When Columbus brought back slaves to Spain, he also caused the question of slavery in the New World to be aired openly, and Queen Isabella decided that her new subjects could not be enslaved. Although Isabella perhaps prevented a few instances of enslavement, the conquest and colonization of the New World were devastating and deadly for Native Americans: the indigenous population dropped by approximately 80% between 1492 and the mid-17th century. The drop was caused mainly by the arrival of Old World diseases, but other Native Americans died as a result of violent conflict or enslavement. Many of those who sailed with Columbus on his second voyage went on to play very important roles in the history of the New World. These first colonists had a great amount of influence and power over the course of the next few decades of history in their part of the world. Sources Herring, Hubert.
