The Gilded Age Essays - 1610 Words

When you are young and even well into your adult years people will tell you there will always be somebody who is smarter, faster, happier, or better at something than you are. This is true for all periods of time but in the Gilded Age those who were better gained more and more crushing the people below them with unprecedented greed, corruption, and power. The few exploited the many by way of opportunity. Something our nation was built on, yet the avaricious elite used it for evil methods. nbsp;nbsp;nbsp;nbsp;nbsp;In the years that followed Reconstruction many issues came up including whether laissez-faire was the correct system to follow.

Rockefeller was also a master of the rebate game. He was one of the most dominant controllers of the railroads. He was so good at the rebate that at some times he skillfully commanded the railroad to pay rebates to his standard oil company on the traffic of other competitors. He was able to do this because his oil traffic was so high that he could make or break a section of a railroad a railroad company by simply not running his oil on their lines. Another one of Rockefellers earlier mentioned but not explained tactics was his horizontally integrated monopoly. Rockefeller use d this horizontal monopoly to set prices and force his competitors to merge with him. (All with Doc. J) Document J shows that Rockefeller had his tentacles, or his influence and power around every piece of the oil industry. That, also, includes the politicians and their support. Rockefeller was an intelligent man who sought for better means in order to increase productivity. He used the opportunities of the time to take advantage of a free system. One of his best characteristics was that he lowered the cost of oil across the word by his largest scale production. To see that his oil was top quality at minimum cost he also hired specialist managers, this was a revolutionary concept at the time.Show MoreRelatedThe Gilded Age : An Analysis Of The Gilded Age793 Words   |  4 Pages The term Gilded age comes from Twain and Dudleys book named the Gilded Age.

Skeletal and Muscular System Relationship free essay sample

Pinak Patel Anatomy and Physiology Professor Jargen December 14, 2011 Skeletal System and Muscular System In anatomy and physiology we study the structure of living things and the function of living systems. In physiology, the scientific method is applied to determine how different organisms, organ systems, organs, cells, and biomolecules carry out the chemical or physical function that they have in the living system. Both anatomy and physiology are subcategories of biology. Throughout our class we have discussed many different systems of the body. One system that is very important to the human body is the muscular system, which consists of three different types of muscle tissue. Along with the muscular system is the skeletal system, which consists of the bones and the different types of tissue it contains. Both of these systems have many different functions, and can be interconnected together. These two systems work together and they form the musculoskeletal system. We will write a custom essay sample on Skeletal and Muscular System Relationship or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The muscular system consists of three different types of muscle tissue and it has four different functions. The muscular system also encompasses many properties. The three different types of muscle tissues it includes are skeletal muscle, cardiac muscle, and smooth muscle. The skeletal muscle’s main function is to move the bones of the skeleton. This muscle is voluntary and is also striated, meaning that it is striped, which is due to the muscle fibers that are combined into parallel fibers. Some of these muscles can be controlled unknowningly. For example, the diaphragm of the human body continues to alternately contract and relax while we are asleep, allowing our lungs to expand to breathe. The cardiac muscle tissue is found only in the heart. It is similar to the skeletal muscle in that it is striated, but it is also different in that it is involuntary. The smooth muscle tissue can be found within the walls of the digestive tract, blood vessels, and airways of the respiratory system. This tissue is nonstriated, which means that it is not striped and the fibers are not arranged into parallel orderly bands like the skeletal and cardiac muscle. The smooth muscle tissue is also involuntary. The muscular system has four key functions. It produces body movements, and stabilizes the body positions, for example, it holds contraction of the neck uscles that hold one’s head upright. Another function of the muscle tissue is that it is the storange and transportation of substances within the body: skeletal muscle contractions move lymph throughout the body, and help return blood to the heart. The final function of the muscle tissue is that it helps to maintain one’s posture. Each skeletal tissue is made of hundreds of t housands of cells called muscle fibers. The fascia is a component of connective tissue and it is a broad sheet of fibrous connective tissue that surrounds and supports muscles and other organs. The external part is the deep fascia that consists of theee layers of connective tissue. The epimysium is the outermost later that encircles the entire muscle. The perimysium surrounds groups of ten to hundereds or more individual muscle fibers, seperating those into bundles called fasicles. Then there is the endomysium, which seperates each individual muscle fiber. The nerve and blood supply of the muscle tissue consists of arteries, veins, and nerves that run together. There are somatic motor neurons that stimulate the muscles to contract. These neurons begin in the brain or spinal cord and extend by an axon to a group of skeletal muscle fibers. All in all, the skeletal muscle tissue contains many vital things, in order for everything to work properly. The skeletal system has many functions as well, just like the muscular system. The skeletal system has six different functions: support, protection, assistance in movement, mineral homeostasis, blood cell production, and triglyceride storage. Unlike the muscular system, posture is not a function of the skeletal system. There are also four types of cells that are present in bone tissue. The first type of cells is the osteogenic cells, which are unspecialized stem cells that are the only bone cells that divide. Another type of cells is the osteoblasts, which are the bone building cells; known as the immature bone cells. Then, there are the osteocytes, which are the mature bone cells and are the main cells in the bone. They exchange nutrients and wastes with the blood, which help maintain the bone’s normal metabolism. Finally, the osteoclasts, which are the cells that release powerful lysosomal enzymes and acids that break down the matrix (resorption). The bone tissue also has nerve and blood supply that also consists of arteries and veins. Although one can claim that there can’t be much inter-relation with the skeletal and muscular system, there are some relations to be made. First of all, vertebrates move by the actions of muscles on bones. Therefore, tendons attach many skeletal muscles across joints, allowing muscle contration to move the bones across the joint. Muscles generally work in pairs to produce movement: when one muscle flexes or contracts, the other relaxes. Next, the skeleton and muscles function together as the musculoskeletal system. This system is often treated as two separate systems, the muscular, and skeletal plays an important homeostatic role: allowing humans to move to more favorable conditions. Certain cells in the bones produce immune cells as well as important cellular components of the blood. Therefore, bone also helps to regulate blood calcium levels, serving as a calcium sink. Finally, the rapid muscular contraction is important in generating internal heat, which is another important function that can relate to bone tissue as well. There are many important systems that we study in anatomy and physiology. The skeletal system and muscular system are just two of them. Both of these systems have many functions that can be studied in depth. Although there are quite a few systems that aren’t very comparable, these two systems make an exception. In conclusion, both of these systems, bones and muscles, work together in many ways and can be inter-related to a certain degree.

UNAB FACULTAD DE COMUNICACION Y ARTES AUDIOVISUALES PROGRAMA DE LITERATURA CAMILO MURCIA SALAZAR Literaturas Europeas Siglos XIX, XX ERIKA ZULAY MORENO BUENO (Docente) Del Aspecto Psico-narrativo en Madame Bovary Madame Bovary de Gustave Flaubert cuenta la historia de una mujer de la sociedad burguesa de Francia a mediados del siglo XIX llamada Emma Bovary. Que con pasion desenfrenada persigue la maravillosa vida que le dicta su imaginacion. Emma trata de llenar sus vacios con las fantasias de sus libros, entre ellas el sexo y lo material. Pero ese deseo incalculable la lleva a tal punto en donde ya no diferencia entre la realidad y la ilusion, desencadenando la destruccion de su vida. Aquel episodio "el baile en Vaubyessard", en el que el descontento de Emma sale a flote; decepcionada de su matrimonio, a causa de la magnifica exhibicion de lujos y excitacion que le produce el exuberante ambiente que la rodea; contempla la satisfaccion de vivir sus ideales sin limites. Sin darse cuenta que cada vez tiene mas temor de caer en el aburrimiento de la realidad. Flaubert proyecta en la novela los efectos contradictorios de la lectura, el vacio de las desilusiones romanticas, asi como las tentaciones que el lujo trae consigo dandole paso a la traicion. A traves de las escenas del baile en Vaubyessard utiliza tecnicas de descripcion desarrollando contrastes, connotaciones negativas, y no aparta el tono ironico con el fin de llevar a cabo su tema. En el capitulo en Vaubyessard son notables la numerosas imagenes recurrentes que describen la vida de Emma y consecuentemente van recreando acontecimientos futuros que el lector puede ir concibiendo. "Emma vestida con el meticulosos cuidado de una actriz lista para hacer su debut" (Flaubert. Pag. 67). De hecho aquel baile era un acontecimiento en la vida real el cual se convertia en el reflejo de los libros de Emma. Y de esa forma ella empezaba actuar como si fuese la heroina del cuento. Y es precisamente esa sensacion lo que ella trata de perseguir por el resto de su vida. Pero los intentos persistentes para construir un mundo deleitable la conducen a la depravacion moral y la destruccion financiera. En ultima instancia su incapacidad por satisfacer sus deseos la conducen a la total desilusion. "un sirviente que se subia a una silla rompio dos cristales de las ventanas, al oir el ruido de los cristales rotos, Madame Bovary miro a su alrededor y vio a algunos campesinos con el rostro pegado a la ventana. - Entonces el recuerdo de Les Bertaux volvio a ella, vio la granja de nuevo-". (Flaubert. Pag.69) El anterior parrafo, no es mas que un "deja vu" que Emma experimenta en aquel baile transformado en una experiencia de ensueno. Pues las imagenes de los cristales rotos pronosticaban la vida destrozada de Emma a causa de la exigencia de sus ideales romanticos. Los campesinos en la ventana representan la realidad de Emma y tambien presagian su eventual amarga decepcion al darse cuenta que todo lo que ha estado persiguiendo no le puede dar su felicidad. Esa imagen del circulo, que se repite en todo el libro representa los diferentes estados emocionales de Emma y como su vida gira en un circulo vicioso. "ellos comenzaron lentamente, luego se movieron mas rapido. Todo giraba alrededor de ellos, las luces, muebles, paneles y el suelo se movian como un disco sobre un eje". (Flaubert, Pag.70). "Emma no dijo nada y observo las ruedas girar" (Flaubert, Pag.70) estas visiones de movimiento giratorio es un imaginario del descontrol de la vida de Emma, pues paradojicamente se encuentra atrapada en una via de escape. Una y otra vez trata de escapar del aburrimiento y la frivolidad de la vida mediante la lectura de novelas, la galanteria, los suenos, los viajes y el lujo. Pero al final nada complace sus sentimientos. "a los largo de la fila de mujeres sentadas revoloteaban los abanicos pintados ocultando sus caras sonrientes y el bouquet de las botellas de perfume con tapas de oro se vertian en las manos entre abiertas. Corceles, broches de diamante y pulseras con dijes temblaban en los cuerpos, brillaban en los senos y sonaban en brazos desnudos". (Flaubert, Pag.68). "se podia escuchar el tintineo
