The Puritans and Plymouth Colony essays

The Puritans and Plymouth Colony essays Amer. governor of the Plymouth Colony for 30 years. A member of the Separatist movement within Puritanism, in 1609 he went to Holland to seek religious freedom. Finding a lack of opportunity there, in 1620 he helped organize an expedition of about 100 Pilgrims to the New World. He helped draft the Mayflower Compact aboard the group's ship, was unanimously chosen governor, and served as governor of the Plymouth Colony for all but five years from 1621 to 1656. He helped establish and foster the principles of self-government and religious freedom that characterized later Amer. colonial government. His descriptive journal provides a unique source of both the voyage of the Mayflower and the challenges faced by the settlers. Bradford was a native of Ansterfield, Yorkshire, in the north of England, where he was born in the year 1588. His pecuniary circumstances were easy, when he followed persecuted Puritans to Holland and became fully identified with them in exile. From early life he had been accustomed to their teachings; and at the age of seventeen years, he attempted to sail to the Netherlands, with some others, where their harassed brethren had gone. Betrayed, he was seized and imprisoned at Boston, in Lincolnshire, for awhile, but finally escaped and joined the fugitives at Amsterdam, where he learned the silk weaver's art and pursued it. On receiving his patrimony, he entered into unsuccessful commercial operations, and lost a greater portion of it. When the establishment of a free colony in America was projected at Leyden, he was one of the most zealous promoters of the measure; and he and his young wife were among the earliest emigrants to that land of promise. Before a site was selected for a settlement, and while the Mayflower was yet riding at anchor in Cape Cod Bay, Mrs. Bradford fell into the sea and was drowned. That was the first death among the Pilgrims after their arrival on the coast of America. Bradford was very popul...

Osmoregulation Definition and Explanation

Osmoregulation Definition and Explanation Osmoregulation is the active regulation of osmotic pressure to maintain the balance of water and electrolytes in an organism. Control of osmotic pressure is  needed to perform biochemical reactions and preserve homeostasis. How Osmoregulation Works Osmosis is the movement of solvent molecules through a semipermeable membrane into an area that has a higher solute concentration. Osmotic pressure is the external pressure needed to prevent the solvent from crossing the membrane. Osmotic pressure depends on the concentration of solute particles. In an organism, the solvent is water and the solute particles are mainly dissolved salts and other ions, since larger molecules (proteins and polysaccharides) and nonpolar or hydrophobic molecules (dissolved gases, lipids) dont cross a semipermeable membrane. To maintain the water and electrolyte balance, organisms excrete excess water, solute molecules, and wastes. Osmoconformers and Osmoregulators There are two strategies used for osmoregulation- conforming and regulating. Osmoconformers use active or passive processes to match their internal osmolarity to that of the environment. This is commonly seen in marine invertebrates, which have the same internal osmotic pressure inside their cells as the outside water, even though the chemical composition of the solutes may be different. Osmoregulators control internal osmotic pressure so that conditions are maintained within a tightly-regulated range. Many animals are osmoregulators, including vertebrates (like humans). Osmoregulation Strategies of Different Organisms Bacteria - When osmolarity increases around bacteria, they may use transport mechanisms to absorb electrolytes or small organic molecules. The osmotic stress activates genes in certain bacteria that lead to the synthesis of osmoprotectant molecules. Protozoa - Protists use contractile vacuoles to transport ammonia and other excretory wastes from the cytoplasm to the cell membrane, where the vacuole opens to the environment. Osmotic pressure forces water into the cytoplasm, while diffusion and active transport control the flow of water and electrolytes. Plants - Higher plants use the stomata on the underside of leaves to control water loss. Plant cells rely on vacuoles to regulate  cytoplasm osmolarity. Plants that live in hydrated soil (mesophytes) easily compensate for water lost from transpiration by absorbing more water. The leaves and stem of the plants may be protected from excessive water loss by a waxy outer coating called the cuticle. Plants that live in dry habitats (xerophytes) store water in vacuoles, have thick cuticles, and may have structural modifications (i.e., needle-shaped leaves, protected stomata) to protect against water loss. Plants that live in salty environments (halophytes) have to regulate not only water intake/loss but also the effect on osmotic pressure by salt. Some species store salts in their roots so the low water potential will draw the solvent in via osmosis. Salt may be excreted onto leaves to trap water molecules for absorption by leaf cells. Plants that live in water or damp environments (hydr ophytes) can absorb water across their entire surface. Animals - Animals utilize an excretory system to control the amount of water that is lost to the environment and maintain osmotic pressure. Protein metabolism also generates waste molecules which could disrupt osmotic pressure. The organs that are responsible for osmoregulation depend on the species. Osmoregulation in Humans In humans, the primary organ that regulates water is the kidney. Water, glucose, and amino acids may be reabsorbed from the glomerular filtrate in the kidneys or it may continue through the ureters to the bladder for excretion in urine. In this way, the kidneys maintain the electrolyte balance of the blood and also regulate blood pressure. Absorption is controlled by the hormones aldosterone, antidiuretic hormone (ADH), and angiotensin II. Humans also lose water and electrolytes via perspiration. Osmoreceptors in the hypothalamus of the brain monitor changes in water potential, controlling thirst and secreting ADH. ADH is stored in the pituitary gland. When it is released, it targets the endothelial cells in the nephrons of the kidneys. These cells are unique because they have aquaporins. Water can pass through aquaporins directly rather than having to navigate through the lipid bilayer of the cell membrane. ADH opens the water channels of the aquaporins, allowing water to flow. The kidneys continue to absorb water, returning it to the bloodstream, until the pituitary gland stops releasing ADH.

How might Archbishop Romero analyze (comment on) the following passage Essay

How might Archbishop Romero analyze (comment on) the following passage from Gaudium et Spes - Essay Example In his view the Church was not the name of the buildings or of the hierarchical structure of clergymen but was the name of the collective of Catholic people, most of who were poor and oppressed (Brockman). The ‘Gaudium et Spes’ (Joy and Hope) apostolic constitution adopted at the Second Vatican Council in 1965 proclaims a similar view of the Church. In this document, the laity are urged to learn what their faith demands from them in the course of their secular duties. They are told that the role of the clergy in this respect is that of a teacher. The clergy will advise them on what God may want them to do, however they should cultivate their own conscience and religious sensibility and not expect explicit guidance from the clergy on every issue (Second Vatican Council). This passage has many parallels with the work of Archbishop Romero. The ‘Gaudium et Spes’ calls for a sort of spiritual and intellectual emancipation of the laity who are to educate themselves in their religion with the help of the clergy and in many matters where the explicit guidance of the Church is not available, they are to use the wisdom of the clergy to determine for themselves what God wants from them. In this view of the Catholic clergy, the clergymen are not the autocratic leaders of the laity but their guides and spiritual advisors. Archbishop Romero too held that the Catholic clergy should not be the leaders or rulers of the people but their advisors and guides. He called for a physical emancipation of the laity from the forces of exploitation and oppression in addition to their spiritual and intellectual liberation. Another aspect of congruence between the teachings and actions of Archbishop Romero and that of the ‘Gaudium et Spes’ is in proclaiming the role of the Catholic Christianity in the secular sphere of existence for a Catholic lay person.

Acquiring a substantial market proportion will require considerable time duration since the industry is expanding gradually. Additionally, the entity does not possess a robust marketing program. The above smart analysis reveals that Point.com

Individualism and Communilism Essay Example for Free

Individualism and Communilism Essay How far can a person go in life without the need of others? Is it possible for him or her to achieve success without having any sort of social dynamic to aid in the progress of their lives? Does having strong social connections aid a person in shaping his or her character to achieve their goals and can these achievement be defined as his or her own if there was intervention of any sort from a social group? It is possible to deduce answers to such notions upon a better understanding of the distinction of community and the individual and the effects of these ideas on each other. The following essay will try to define the distinction between the ideas of communalism and individualism. It will try to isolate the characteristics of each ideal in order to better comprehend their influence on a person life and try to provide an argument on why these two ideas may need to work together in order for a person to lead a fulfilling life. Communitarianism defines the idea where the individual needs of a person are secondary to the overall development of the social group he or she communes. The social group can be represents as any group of people that share common goals and ideals. Possible factors that define ideals of the group include ethnic background, social or economic status, religious and cultural beliefs. Constant social interaction is important with this ideal. It is communitarian teleology that humankind is social by nature and that this idea grows naturally to this end. Aristotle was a proponent of communitarianism and – according to class lectures on the subject – believed that being part of a community eased the burden of everyday living. He provided an example on the natural development of speech as a direct result of the necessity of humans to interact with each other to participate in a community. He also hypothesized that in order for human development to flourish there needs to be a sharing of skills and ideas within the social group. The contrasting idea to communitarianism is individualism. Individualism focuses on the idea of the promotion of an individual thoughts and desires before those of a social group. This idea believes that external involvement from others is unnecessary when trying to achieve an individual’s goals, unless the external interference aids in the achievement of the individuals goals. Advocating social isolationism is not a necessary factor under this ideal; rather the individualist is often part of a social group and adheres to the communal laws and practices set forth upon them in order to promote their own personal gain. Thomas Hobbes defines an extreme extend of complete individualism. He states, that under individualism, humans care only about themselves and have no regards for the necessity of others and have no moral concern for their actions. Under this state of reality, it seems highly unlike for human development to expand as all focus lie on achieving individual goals for the sake of individual gain rather than sharing the results of intellectual, social, economic, etc. endeavors. Hobbes realized that such a state of reality cannot naturally exist and deduced that the individualist enters society and agrees to abide by its rules and regulations with the sole purpose of expanding their own personal goals; he coined this compromise â€Å"the social contract. † Based on the interpretations of the ideals of communitarianism and individualism it is possible to obtain an idea on how these ideals shape the individual’s outlook on life. Communitarianism appears to promote the well-being of all, the question to this is at what cost? The idea that the needs of the many are more important than the needs of the one fails to account for moral responsibility. If we explore individualism further and do not use the extreme representation of the term, we realize that being an individual actually means being free to make choices outside of what other people expect or dictate. In other words, by being an individual you are free to choose and are directly responsible for your actions and their moral implications. Being an individualist is to have free will. It is impossible to deny that humans tend to gravitate toward the state of a social-collective and in fact, there is evidence that social interaction is necessary. For example, as children we tend to obtain knowledge from many others. We do not learn from one person or one experience, rather we continue to expand our knowledge and thereby our self. In this sense, communitarianism works by providing the individualist with the tools to make choices and commit to actions, but it does not dictate how this person will use the knowledge. It is up to the individual and his singular choice to decide how to use this knowledge. Communitarianism may hinder personal development. If the individual considers the needs of his community, before his own how can he or she expect to develop as a person? In fact, in some cases, the community will try to keep an individual from growing. For example, in certain communities poverty is the prevalent norm. If the person acts to try to remove him or herself from such a community through his own achievements, some in such community may see him in a different light, not wanting to be part of the group anymore. This sense of guilt can weight on the individual and create doubt on his achievements and on himself. Although he or she was free to make the conscious choice to get out from poverty, the community still has an indirect control over the person. Communitarianism may also interfere with a clear sense of moral judgment. In general, a person’s self-worth and values are defined by their individual actions. In some cases, communitarianism blurs the distinction between the values of the individuals and the values of the group. In such instances, wrongful generalizations of a person values and choices can be made based solely on the choices and values of the community they belong to; this is called stereotyping and/or racism. It is unclear how the will of others can influence the moral decisions of a person. Communitarianism can server a person in the early stages of life (when individual thought and reasoning are not fully developed) to provide the tools necessary to shape their life. However, in the end, the individualistic actions of a rational, independent, free-to-choose individual that define a person.

Physics of the Internal Combustion Engine :: physics motor engine ICE

Background Infromation In Cambridge England, in 1820 a man by the name of Reverend W. Cecil was explaining to fellow scientists and inventors how an internal combustion engine worked. All of his fellow colleagues just laughed at him and told him it could never be done. In 1860 Jean Joseph E'tienne Lenoir made Cecil's idea come to life by building the first practical internal combustion engine. Three years later in 1863 Lenoir built one of the worlds first gas engine cars. Ignition System Have you ever wondered how turning a simple key will start a car? Well, I'll tell you. When you turn the key a small voltage from the cars battery is sent to the coil. The coil turns the small voltage into a large voltage. Then the coil sends the the voltage to the distributor. The distributor has heavy wires that send the voltage to each spark plug. The distributor, also, tells the spark plugs which one should fire and when to fire. The altenator is another part of the ignition system. The basic job of the altenator is to make more voltage to charge the battery. Fuel System Everyone knows that you need to have gas in your car for it to run. When you put gas into the car it goes into the gas tank. The gas then makes its way from the tank to the carberator via the fuel pump. The carberator mixes the gas and air together. The air is first cleaned by the air filter before going to the carberator. The air and gas mixture is then sent to the intake manifold, from there its sent to the intake valve. Combustion The camshaft opens and closes both the intake valve and the exhust valve. When the intake valve opens, the air and gas mixture rush into the cylinder. The valve closes and the mixture is traped inside. The piston is pushed up and causes compression. At just the right moment the spark plug sparks and ignites the mixture. When the gas explodes it pushes the piston back down. When the piston is at the bottom of the stroke, the exhuast valve opens sending the exhaust out through the tail pipe. Exhaust System Once the burnt fuel is throught the exhaust valve it is sent to the exhaust manifold. The exhaust maniflod is just a collecting area for the exhaust coming from the cylinders. Pressure keeps the exhaust moving to the pipes then into the muffler.

AFrican American equality Essay

From the time our country was founded, many African Americans lived a life of hardship merely because the color of their skin. In many instances they were treated as animals, being sold and traded in shackles and chains. At the time of the signing of the Declaration of Independence when the country was founded, most African Americans worked as slaves. Working conditions for slaves were inhumane, who were often forced to work long hours in the sweltering summer heat. In 1865, the ratification of the 13th amendment made slavery illegal everywhere in the United States. However, this was not the end of inequality and segregation for African Americans. The racism in the south did not stop just because slavery ended. For decades after the end of slavery, laws such as the Jim Crow laws significantly limited African American’s rights and freedoms. In addition, share-cropping allowed servitude to continue only in a different form. Former slaves were now financially bound to their land. These laws significantly disheartened American Americans right and fight for equality – a battle that did not really get started until the civil rights era. In one of the greatest moments in American history when MLK gave his speech on the inequality of races. In one line he said â€Å"the negro lives on a lonely island of poverty in the midst of a vast ocean of prosperity†. This meant that even though there was a great economic boom the blacks were not sharing the wealth. Instead of blacks sharing the great wealth of this time they were left out of the boat by being ineligible force retain perks that the white man had been innate to. In an truly inspiring line of his speech MLK says â€Å"the negro community must not lead to distrust all white people, for many of our white brothers, as evidenced by their presence here today, have come to realize that their destiny is tied up with our destiny†. This says that not all the white men are prejudice which would be just as stereotypical as anything else done against blacks at the time. This is truly encouraging saying that blacks have been persecuted for hundreds of years and some still find ways to show some remorse toward them. In one of the most famous lines of the speech MLK says â€Å"I have a dream that one day this nation will rise up and live out the true meaning of its creed: â€Å"We hold these truths to be self-evident:that all men are created equal†. He means that he hopes one day that all men with see each other not on the basis of skin color but by the content of the character which is perfectly expressed in â€Å"I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. † Martin Luther king speech expresses the inequality blacks felt. The civil rights movement took time and many brave people. However even after all the protest and laws passed to help equal the races the blacks still do not have the same freedoms as whites. Most blacks live inner cities and are not treated with dignity that they deserve in humans. They are constantly unfairly prosecuted by law enforcements and are scapegoated by many people of the root of the problem. However there has been a major increase in freedoms they have gained over time. Since MLK speech they have gained equality and it should be so far in the future that they are looked at as complete equals.
